our goal: to alleviate poverty by expanding access to digitally-based financial tools and services.
At A Glance
Increasing poor people’s access to financial services can help them weather personal financial crises and increase their chances of climbing out of poverty.
About 80 percent of the world’s poor adults do not have a bank account or use other formal financial services—not only because of poverty but also due to costs, travel distance, and other barriers.
Our strategy aims to capitalize on rapid advances in mobile communications and digital payment systems to connect poor households to affordable and reliable financial tools.
Our Financial Services for the Poor strategy, updated in 2012, is led by Rodger Voorhies, director, and is part of the foundation’s Global Development Division.
Poor people do not live in a static state of poverty. Every year, many millions of people transition out of poverty by successfully adopting new farming technologies, investing in new business opportunities, or finding new jobs. At the same time, large numbers of people fall back into poverty due to health problems, financial setbacks, and other shocks. If available at critical moments, effective tools for savings, payment, credit, and insurance can help households capture an opportunity to climb out of poverty or weather a crisis or emergency without falling deeper into poverty.
Worldwide, approximately 2.5 billion people do not have a formal account at a financial institution, according to the World Bank’s Global Financial Inclusion Database. As a result, most poor households operate almost entirely in the cash economy, particularly in the developing world. This means they use cash, physical assets (such as jewelry and livestock), or informal providers (such as money lenders and payment couriers) to meet their financial needs—from receiving wages to saving money for fertilizer. However, these informal mechanisms tend to be insecure, expensive, and complicated to use. And they offer limited recourse when major problems arise, such as a serious illness in the family.
A growing body of evidence suggests that increasing poor people’s access to better financial tools can help accelerate the rate at which they move out of poverty and help them hold on to economic gains. However, it is costly to serve poor people with financial services, in part because most of their transactions are conducted in cash. Storing, transporting, and processing cash is expensive for banks, insurance companies, utility companies, and other institutions, and they pass on those costs to customers.
A foundation-supported initiative allows Rwandan farmers to access markets for their beans and maize using mobile phones.
In wealthier countries, people conduct most of their financial activities in digital form, and value is stored virtually and transferred instantaneously. The global revolution in mobile communications, along with rapid advances in digital payment systems, is creating opportunities to connect poor households to affordable and reliable financial tools through mobile phones and other digital interfaces.
In fact, research has shown that the most effective way to significantly expand poor people’s access to formal financial services is through digital means. In addition to cost savings, digital financial services offer a wide array of benefits:
- They connect poor people to the formal financial sector and enable them to become customers and suppliers within the wider economy.
- Financial flows can be accurately tracked, resulting in safer and speedier transactions and less corruption and theft.
- Providers can use financial histories to develop products that are better suited to customers’ needs, cash flow, and risk profiles, including fee-for-service offerings and smaller-unit transactions.
- Direct deposits (including wages and government assistance) allow money to “bypass” the home, helping users save rather than spend and often giving women more financial authority within the family.
- Automatic reminders, positive default options, and other choices offered via mobile phone menus offer convenience and save time.
The Bill & Melinda Gates Foundation’s Financial Services for the Poor program aims to play a catalytic role in broadening the reach of digital payment systems, particularly in poor and rural areas, and expanding the range of services available on these platforms. Until the infrastructure and customer base are well established, this might involve a combination of mobile banking services that are accessible via cell phones and brick-and-mortar stores where subscribers can convert cash they earn into digital money (and vice-versa).
Our approach has three mutually reinforcing objectives:
- Reducing the amount of time and money that poor people must spend to conduct financial transactions
- Increasing poor people’s capacity to weather financial shocks and capture income-generating opportunities
- Generating economy-wide efficiencies by digitally connecting large numbers of poor people to one another, financial services providers, government services, and businesses

We are not focused on a particular product or distribution channel, but rather on innovative ways to expand access and encourage markets. At the same time, we are aware that interventions in this and other areas too often involve technologies that are made available to the intended users but are not adopted. To address this demand-side challenge, we are supporting research and product design experiments to identify design features, price incentives, and marketing messages that will encourage poor people to adopt and actively use digital financial services. We are also supporting policymakers as they work to develop policies and regulations that facilitate these developments.
We believe that the combined effect of these interventions will accelerate the rate at which poor people transition out of poverty and decrease the rate at which they fall back into poverty. Our strategy also recognizes that countries are at different stages in developing an inclusive digital financial system and that we must tailor our interventions accordingly.
Areas of Focus
Our work falls into four areas:
Digital payment systems
In countries with a minimum level of connectivity in poor and rural areas, we work with in-country providers to extend the reach of digital payment systems into those communities and encourage poor people to adopt these systems through a mobile phone or other digital interface. Payment systems are crucial because they enable people to collect payments from customers, buy goods, pay for water and electricity, and send money to friends, family, and business partners. They also enable governments to collect taxes and disburse social payments. When these transactions are costly and inconvenient, economic activity is impeded.
Digital financial services
In countries where digital payment systems have taken hold in poor and rural communities, we work with banks, insurance companies, and other providers to increase the range of financial services that people can access in digital form. Many of these services are designed to meet the specific household management needs of low-income people, particularly smallholder farmers and women.
We work at the global level with governments, donors, financial standards-setting bodies, and the private sector to maximize our collective impact on poor people’s access to financial services.
Research and innovation
We collect data to measure the impact of our grants and interventions and to help key stakeholders make better decisions. We also conduct research and nurture innovations that could lead to longer-term improvements in delivering digital financial services on a broad scale.

Discovered in 1988, the Roman Hippodrome in Beirut is situated in Wadi Abou Jmil, next to the newly renovated Jewish Synagogue in Downtown Beirut. This monument, dating back for thousands of years, now risks to be destroyed.
The hippodrome is considered, along with the Roman Road and Baths, as one of the most important remaining relics of the Byzantine and Roman era. It spreads over a total area of 3500 m2.
Requests for construction projects in the hippodrome’s location have been ongoing since the monument’s discovery but were constantly refused by former ministers of culture of which we name Tarek Metri, Tamam Salam and Salim Warde. In fact, Tamam Salam had even issued a decree banning any work on the hippodrome’s site, effectively protecting it by law. Salim Warde did not contest the decree. Current minister of culture Gabriel Layoun authorized constructions to commence.
When it comes to ancient sites in cities that have lots of them, such as Beirut, the current adopted approach towards these sites is called a “mitigation approach” which requires that the incorporation of the monuments in modern plans does not affect those monuments in any way whatsoever. The current approval by minister Layoun does not demand such an approach to be adopted. The monument will have one of its main walls dismantled and taken out of location. Why? to build a fancy new high-rise instead. Minister Layoun sees nothing wrong with this. In fact, displacing ruins is never done unless due to some extreme circumstances. I highly believe whatever Solidere has in store for the land is considered an “extreme circumstance.”
The Roman Hippodrome in downtown Beirut is considered as one of the best preserved not only in Lebanon, but in the world. It is also the fifth to be discovered in the Middle East. In fact, a report (Arabic) by the General Director of Ruins in Lebanon, Frederick Al Husseini, spoke about the importance of the monument as one that has been talked about in various ancient books. It has also been correlated with Beirut’s infamous ancient Law School. He speaks about the various structures that are still preserved and only needing some restoration to be fully exposed. He called the monument as a highly important site for Lebanon and the world and is one of Beirut’s main facilities from the Byzantine and Roman eras, suggesting to work on preserving and making this site one of Beirut’s important cultural and touristic locations. His report dates back from 2008.
MP Michel Aoun, the head of the party of which Gabriel Layoun is part, defended his minsiter’s position by saying that: “there are a lot of discrepancies between Solidere and us. Therefore, a minister from our party cannot be subjected to Solidere. Minister Layoun found a way, which is adopted internationally, to incorporate ancient sites with newer ones… So I hope that media outlets do not discuss this issue in a way that would raise suspicion.”
With all due respect to Mr. Aoun and his minister but endangering Beirut’s culture to strip away even more of the identity that makes it Beirut is not something that should concern him or Solidere. What’s happening is a cultural crime to the entirety of the Lebanese population, one where the interests of meaningless politicians becomes irrelevant. Besides, for a party that has been anti-Solidere for years, I find it highly hypocritical that they are allowing Solidere to dismantle the Roman Hippodrome.
The conclusion is: never has a hippodrome been dismantled and displaced in any parts of the world. Beirut’s hippodrome will effectively become part of the parking of the high-rise to be built in its place. No mitigation approach will be adopted here. It is only but a diversion until people forget and plans go well underway in secrecy. But the time for us to be silent about this blatant persecution of our history cannot continue.
If there’s anything that we can do is let the issue propagate as much as we can. There shouldn’t be a Lebanese person in the 10452 km2 that remains clueless about any endangered monument for that matter. Sadly enough, this goes beyond the hippodrome. We have become so accustomed to the reality of it that we’ve become very submissive: the ancient Phoenician port is well behind us, there are constructions around the ancient Phoenician port of Tyre and the city itself risks of being removed off UNESCO’s list for Cultural Heritage Sites.
The land on which ancient monuments are built doesn’t belong to Solidere, to the Ministry of Culture or to any other contractor – no matter how much they’ve paid to buy it. It belongs to the Lebanese people in their entirety. When you realize that of the 200 sites uncovered at Solidere, those that have remained intact can be counted with the fingers of one hand, the reality becomes haunting. It’s about time we rise to our rights. Beirut’s hippodrome will not be destroyed.

Types of Builds
Millard Fuller used to say that a home is the foundation on which human development occurs. It is also an important, positive step in working on a safer, healthier and more responsible future. Many people struggling to put food on the table, pay bills, purchase school supplies and clothing and maintain transportation to work are not thinking about repairing their homes, even though those homes might be dangerous, literally crumbling around them and their children.
The Fuller Center is an organization devoted to partnership, renewed opportunity and providing a hand up instead of a hand out. The construction and rehabilitation of simple, decent houses are the two basic ways we do this.
The work of The Fuller Center allows the elderly to live out their rest of their days comfortably in their own homes, gives families a fresh start, enables the handicapped to maintain a level of independence in accessible homes and, in some cases, transforms entire neighborhoods.

Biochemical Conversion Processes
The diagram below depicts a high-level view of the primary units of operation in the biochemical conversion process. Specific process operation conditions, and inputs and outputs within and between each unit, vary in practice. These process variations can impact the key performance outcomes (titer, rate, and yield), which determine economic viability when the process is scaled up. The following descriptions highlight issues in each key process step.
During pretreatment, biomass feedstock undergoes a process to mechanically or chemically fractionate the lignocellulosic complex into soluble and insoluble components. Soluble components include mixtures of five- and six-carbon sugars (mainly xylose, arabinose, mannose, galactose, and glucose) and some sugars oligomers. Insoluble components include cellulosic polymers and oligomers and lignin (and any other components that may be linked to the constituents). Depending on the exact chemistry chosen for this step, variable amounts of the biomass may be solubilized. The main purpose of this step is to open up the physical structure of the plant cell walls to permit further deconstruction during the hydrolysis stepyea. The more open structure of the resulting material makes the remaining carbohydrate polymers more accessible for hydrolytic conversion to soluble sugars by enzymes or chemicals. The specific mix of sugars and oligomers released depends on the feedstock used and the pretreatment technology employed.
In some process configurations, the pretreated material goes through a hydrolysate conditioning and/or neutralization process to adjust the pH of the biomass slurry and remove undesirable by-product from pretreatment that are toxic to the downstream fermenting microorganism. In some cases, this step and hydrolysis, the next step, are combined into a single process.
In hydrolysis, the pretreated material, with the remaining solid carbohydrate fraction, primarily cellulose, is guided through a chemical reaction that releases the readily fermentable sugar, glucose. This can be accomplished with enzymes, such as cellulases, or with strong acids. Addition of other enzymes in this step, such as xylanases, may allow for less severe pretreatment conditions, potentially resulting in a reduced overall pretreatment and hydrolysis cost. Depending on the process design, enzymatic hydrolysis requires several hours to several days, after which the mixture of sugars and any unreacted cellulose is transferred to the fermenter. Current processes use purchased enzymes or enzymes manufactured on site, based on the economics of the specific process. For technologies using strong acids, acid recovery is important for the economics to be viable.
Currently, the most common approach to biological processing is to employ a fermentation step, wherein an inoculum of a fermenting microorganism is added to the biomass hydrolysates. Fermentation of all sugars is then carried out, and after a few days of continued saccharification and fermentation, nearly all of the sugars are converted to biofuels or other chemicals of interest. The resulting aqueous mixture or two-phase broth is sent to product recovery. Some processes combine the hydrolysis and fermentation steps (i.e., simultaneous saccharification and fermentation [SSF]).
Chemical or catalytic conversion can be used in place of, or in addition to, fermentation to convert the hydrolysis products, such as sugars, alcohols, or a variety of other stable oxygenates, to desired end products. The addition of a catalyst makes the reaction less energy intensive, thus making the entire process more efficient. Different reactions achieve different yields and intermediates while targeting different end fuels and chemicals, so current research is aimed at identifying optimal process combinations with respect to efficiency, feedstock utilization, cost, sustainability, finished product characteristics, and anticipated market demands.
Product Upgrading and Recovery
Product upgrading and recovery varies based on the type of conversion used and the type of product generated, but in general, involves any biological and chemical transformations, distillation or any other separation and recovery method, and some cleanup processes to separate the fuel from the water and residual solids. Residual solids are composed primarily of lignin, which can be burned for combined heat and power generation or chemically converted to intermediate chemicals or intermediates for other uses.

European Painting before 1900, Johnson Collection
Triptych showing scenes from the Martyrdom of Saint Barbara and scenes from the Life of Christ
Master of the Laufen High Altarpiece, Austrian (active Salzburg), dated work 1467
Oil and gold on panels
EW1993-127-2a--cPurchased with the W. P. Wilstach Fund, the George W. Elkins Fund, and Museum funds, 1993
As described in The Golden Legend, written in about 1267 by Jacopo da Voragine, Saint Barbara converted to Christianity against the wishes of her pagan father. Locked in a tower by him, she ordered workmen to construct a third window inthe building to symbolize the Christian trinity. Enraged, her father turned her over to the Roman authorities for torture, and when her execution was ordered,he himself beheaded her. The left and right panels on the front of this triptychillustrate episodes from Barbara’s gruesome martyrdom.
These graphic depictions are intended to help the viewer equate Barbara’s physical torments with those of Christ, whose crucifixion is depicted in the top center composition. The figures at the top left and right, probably the apostles John and Luke, hold sayings taken from the last words of Christ on the cross, which here apply also to Barbara’s death. The bottom center panel shows Barbara enthroned in heaven, wearing a crown and holding a palm frond as symbols of victory over death. A tower and chalice, her identifying attributes, appear nearby.
Barbara’s martyrdom is paralleled on the reverse by the resurrected Christ standing in the tomb. The left and right panels of the back, which are movable and can be folded shut to appear on the front, show the angel Gabriel announcing the incarnation of Christ to the Virgin Mary.

International Women’s Day (IWD) was founded in 1910 in order to confront the great inequalities women faced in the labor force and society as a whole. Unfortunately, one hundred years later, women still make up a majority of the world’s poor.
Women’s wages in the U.S. are only 76% of men’s, but the disparity of long-term earnings between men and women is far worse. A study comparing total earnings between 1983 and 1998 showed women averaging just 38% of men’s wages (Institute for Women’s Policy Research, 2004).
In large part, this is because 80% of American women under 40 are mothers, according to the U.S. census. Without adequate paid maternity leave, mothers are frequently forced to quit stable jobs and disrupt career plans. Add to that $611 in average monthly childcare costs (U.S. Department of Labor), which is more than two weeks pay at the federal minimum wage.
Eighty-seven percent of single parent households are headed by women and of those 37% are in poverty (Association for Women’s Rights and Development). Once a family falls into poverty it is astoundingly hard for them to escape. Sixty percent of families that are in the bottom fifth of income remain there a decade later (Association for Women’s Rights and Development).
The impact of the financial crisis, however, is worldwide. Of the 1.5 million people living on a dollar or less per day, 70% are women (UN.org). Forced into the factories with the worst working conditions, women make up 90% of the world’s sweatshop labor (Women Thrive Worldwide). Often being laid off, these women are accustomed to making 13 cents to one dollar per hour (Powell and Skarbek 2004). Forced to work, women are less likely to attend school or leave the home before marriage. Seventy-seven million girls of primary school age worldwide are out of school, compared to only 55 million boys (The World Bank).
Women around the world are bound together by discrimination and economic servitude created by capitalism. Their work is devalued down to pennies, and often the largest use of their time - household labor - goes unpaid. IWD is a chance to remember and celebrate the struggles of women, which have won huge improvements in our lives. If women united internationally and with the wider struggles of working people to fight for equal rights, better working conditions, wages and stronger social services such as health care, child care and food support, we could collectively improve conditions for all.

A Soyuz rocket launched two Galileo satellites into orbit on Friday, marking a crucial step for Europe’s planned navigation system, operator Arianespace announced.
The launch took place at the Kourou space base in French Guiana, at 3:15pm (6:15pm GMT).
Three and three-quarter hours later, the 700kg satellites were placed into orbit.
The new satellites add to the first two in the Galileo navigation system, which were launched on Oct. 21, last year.
Together they create a “mini-constellation.” Four is the minimum number of satellites needed to gain a navigational fix on the ground, using signals from the satellite to get a position for latitude, longitude, altitude and a time reference.
Galileo will ultimately consist of 30 satellites, six more than the US Global Positioning System.
By 2015, 18 satellites should be in place, which is sufficient for launching services to the public, followed by the rest in 2020, according to the European Space Agency.
It is claimed that the system will be accurate to within one meter. The US Global Positioning System, which became operational in 1995 and is currently being upgraded, is currently accurate to between three and eight meters.
In May, the European Commission said the cost by 2015 would be 5 billion euros (US$6.45 billion).
As a medium-sized launcher, Soyuz complements Europe’s heavyweight Ariane 5 and lightweight Vega rockets.

Forget the batteries for a second, thats just one of a thousand analogies you could use to describe voltage/current and the reason that no current flows has nothing to do with the electro-chemical properties of batteries, its far simpler.
The easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for current to return to its source, there will be no current flow.
In your battery example, there is no return current path so no current will flow. There is obviously a more deep physics reason for why this works but as the question asked for a simple answer I'll skip the math, google Maxwell's Equations and how they are used in the derivation of Kirchhoff's voltage law.
Batteries do make a good example for this simply because they are current sources with completely isolated grounds. This example would be equally true of any other power source with a completely isolated "ground".
However, this is not an easy thing to find, for instance doing this with 2 bench supplies would likely make one of the bench supplies very unhappy, but thats not because the effect is different, the difference is that the bench supplies are likely both grounded to the electrical wiring in the building and as such there is a return path for current to flow through.
The water analogy for this also effective. Think of your battery example this way:
You have a water pump (battery A) connected to a pipe (the wire), and you have another water pump (battery B) connected to the same pipe (the wire) . Now in your example the there is no return path in the system so imagine that the pipe is full of water but capped off on both ends.
You hit the power switch on the pumps, what happens?
The answer is nothing, there is no where to move the water to, the pumps don't even spin. (ignore water turbulence like effects for this analogy).
Now if you were to connect the pipe in a loop and hit the switch the pumps would spin up (voltage) and water would flow (current).
If you used 2 difference speed pumps (different voltage batteries) and faced them toward each other one will over power and cause the other to spin in the wrong direction (burn out just like connecting a 9V and 6V battery in parallel).
If you connected both pumps pointing in the same direction you would get more water pressure (voltage) because the pumps are helping each other out (2 batteries in series).

Problem 367Published on Saturday, 14th January 2012, 10:00 pm; Solved by 247
Bozo sort, not to be confused with the slightly less efficient bogo sort, consists out of checking if the input sequence is sorted and if not swapping randomly two elements. This is repeated until eventually the sequence is sorted.
If we consider all permutations of the first 4 natural numbers as input the expectation value of the number of swaps, averaged over all 4! input sequences is 24.75.
The already sorted sequence takes 0 steps.
In this problem we consider the following variant on bozo sort.
If the sequence is not in order we pick three elements at random and shuffle these three elements randomly.
All 3!=6 permutations of those three elements are equally likely.
The already sorted sequence will take 0 steps.
If we consider all permutations of the first 4 natural numbers as input the expectation value of the number of shuffles, averaged over all 4! input sequences is 27.5.
Consider as input sequences the permutations of the first 11 natural numbers.
Averaged over all 11! input sequences, what is the expected number of shuffles this sorting algorithm will perform?
Give your answer rounded to the nearest integer.

Quincy’s first permanent Jewish resident was Abraham Jonas, an English-born Jew, who prior to his arrival in 1838 had lived in Cincinnati with other members of the Jonas family, had moved to Williamstown, KY where he was merchant and representative in the Kentucky state legislature, and where he had been the Grand Master of Kentucky Lodge of Masons in 1832. Why Jonas uprooted his family and came to the wilds of Illinois remains unclear. Beginning as a carriage, chair, window, and paint merchant, Jonas quickly plunged into local Masonic and political affairs. In 1840 he was elected the first Grand Master of the Illinois Masonic Lodge and in 1841 he was elected to his only term in the Illinois legislature as a member of the Whig Party. Jonas has characterized as quick in perception, a brilliant debater, and a formidable opponent. It was during this one term that he met Abraham Lincoln and their political friendship was solidified. Historians have said that Jonas was Lincoln’s closest Jewish friend, and it was Jonas who helped propel Lincoln’s candidacy for President.
Two of Jonas’s brothers, Samuel and Edward, followed him to Quincy at the end of 1840 or early 1841. These three English Jews quickly blended into the small town, with Samuel becoming one of the founders of the Quincy Public Library. Abraham studied law and was admitted to the bar. His activities on behalf of the Whig Party resulted in his appointment as Postmaster of Quincy in 1849.
At about the same time the first wave of German born Jews began to settle in Quincy. Several had been peddlers and decided to settle down in Quincy. Men like David Hermann who arrived in 1846 and Moses Jacobs in 1847 became successful merchants. When recalling those early years, Moses Jacobs noted that by 1849 there were enough Jews to conduct high holiday services on an annual basis, usually in someone’s home. By 1851 the little community had collected enough funds to allow Edward Jonas to purchase a parcel of land overlooking the Mississippi River for a cemetery. By 1852 it was reported that “the Israelites of Quincy had commenced a congregational organization, by electing a Schochet…” When Rabbi Isaac Mayer Wise made a one day stop in Quincy on July 16, 1856, he noted that “there are about 40 souls of the Jewish persuasion hailing from Germany, Poland and England. They do a flourishing business.” He also wrote that they would have a nice little congregation if they could overcome their business jealousy.
By the end of that year, those jealousies had been set aside as 26 families founded K. K. B’nai Abraham, and one year later Reverend Israel Worenski became their spiritual leader as Chazzan and Schochet. The congregation met in the third floor of the Jonas building at the southeast corner of Fifth and Hampshire, across from the town square. This “traditional” congregation grew as more Jews settled in Quincy because of its economic prospects. By 1859 Moses Jacobs reported that there were thirty members, or about 100 residents of all ages. Regular Sabbath services were led by the Chazzan, and the congregation supported the services of a Schochet.
Until this point there is nothing to show that Jews faced any kind of discrimination, and the onset of the Civil War acted to further integrate Jews into the life of the community. Lincoln appointed Jonas to the position of Postmaster, Jewish men enlisted in the military, and several of Quincy’s Jewish women helped to found and to activate the Needle Pickets to assist families of Union soldiers. However, there were stirrings of secession within the Jewish community. When the congregation met in 1861 to elect a Chazzan and lecturer, and a Schochet, Mohel, and Shamus, eight members, mostly Bavarians, threatened to leave. Differences were set aside and Nathan Hainsfurther, a resident of Winchester, Illinois, who attended high holiday services in 1861, said, “None of the greater congregations of the country could offer any more to the devout mind than is the case here. The place of worship is a nice hall supplied with everything necessary to a synagogue, and was very well attended.”
One year later the members of B’nai Abraham had collected enough funds to begin the process of building their own house of worship. Such a place was found across from Jefferson Square. Edward Jonas solicited more funds through the newspaper The Occident in which he noted 45 paying members comprising two hundred persons, a Chazzan and teacher, and “a location in a beautiful city of 20,000 on the banks of the Mississippi which offers a peaceful and prosperous home.”
The rift in the congregation had not healed and on October 18, 1864, seventeen members held a meeting in their place of worship to elect officers and establish a new congregation. These “reformers” wanted to break from the old ways and establish a congregation that reflected the American way. This congregation called itself K.K. B’nai Sholom, and by 1866 it was renting an old Baptist Church as its home.
Meanwhile, just prior to the high holidays in 1866, B’nai Abraham dedicated its synagogue. Designed to hold 200 persons, the sanctuary was 18 feet high, with seats on both sides of a central aisle, one for men and the other for women. The building was lit with gas and handsomely carpeted. The dedication was service was attended by both Jews and Gentiles, but noticeably absent were members of B’nai Sholom.
Perhaps in an attempt to placate the secessionists, B’nai Abraham in 1868 introduced an organ and choir into its services. But B’nai Sholom was already planning its own synagogue on Ninth Street between Broadway and Spring. None other than Rabbi Isaac Mayer Wise dedicated the cornerstone on July 18, 1869. Just prior to this, in May 1869, B’nai Abraham suffered a mortal blow, when fire damaged its wooden synagogue. When Temple B’nai Sholom was dedicated on September 8, 1870, it literally towered over B’nai Abraham. Costing $25,000, this red brick structure followed a neo-Byzantine style of architecture, dominated by six story high Moorish towers. At nine stories in height, this building was easily recognizable in the Quincy skyline. Some traditionalists had left B’nai Abraham to become charter members of B’nai Sholom.
Reasonable individuals began to conduct behind the scenes negotiations, but it took Rabbi Adolph Ollendorf of B’nai Abraham to effect a merger. He gradually introduced reforms in B’nai Abraham and his eloquent speeches probably spurred the members to bring about a merger of the two congregations. On July 29, 1872, the two congregations passed resolutions of merger. The following Friday evening the first joint Shabbat service was held at B’nai Sholom, with the final Shabbat day service at B’nai Abraham the next day. Herman Hirsch wrote that "Peace, harmony and good will now exists among the members of the united congregations…for in union lies strength….”
This moment was the apex of Jewish life in Quincy. Social and economic forces in the wider country were having an effect. Quincy’s river traffic gave way to the railroad, Quincy’s was no longer a frontier community, and Quincy’s younger generation of Jews sought to make their fortunes and find their spouses elsewhere. Orthodox Judaism as a mode of worship for Quincy’s Jews had been cast aside in favor of Reform. The size of the Jewish community inexorably declined, and Rabbi Elias Eppstein, Quincy’s rabbi in the 1890s thought that the community was on the verge of death. But Congregation B’nai Sholom has survived, now numbering approximately 65 members, and its building, although changed in appearance, remain the second oldest continuously used synagogue west of the Allegheny Mountains and the oldest in Illinois.

Nausea and vomiting - adults
Nausea is the feeling of having an urge to vomit. It is often called being sick to your stomach.
Vomiting or throwing up is forcing the contents of the stomach up through the esophagus and out of the mouth.
Emesis; Vomiting; Stomach upset; Upset stomach
Many common problems may cause nausea and vomiting:
Nausea and vomiting may also be early warning signs of more serious medical problems, such as:
Once you and your doctor find the cause, you will want to know how to treat your nausea or vomiting
. You may be asked to take medicine, change your diet, or try other things to make you feel better.
It is very important to keep enough fluids in your body. Try drinking frequent, small amounts of clear liquids
If you have morning sickness during pregnancy, ask your doctor about the many possible treatments.
The following may help treat motion sickness:
- Lying down
- Over-the-counter antihistamines (such as Dramamine)
- Scopolamine prescription skin patches (such as Transderm Scop) are useful for extended trips, such as an ocean voyage. Place the patch 4 - 12 hours before setting sail. Scopolamine is effective but may produce dry mouth, blurred vision, and some drowsiness. Scopolamine is for adults only. It should NOT be given to children.
Call your health care provider if
Call 911 or go to an emergency room if:
- You think vomiting is from poisoning
- You notice blood or dark, coffee-colored material in the vomit
Call a health care provider right away or seek medical care if you or another person has:
Been vomiting for longer than 24 hours
Been unable to keep any fluids down for 12 hours or more
Headache or stiff neck
Not urinated for 8 or more hours
Severe stomach or belly pain
Vomited three or more times in 1 day
Signs of dehydration include:
- Crying without tears
- Dry mouth
- Increased thirst
- Eyes that appear sunken
- Skin changes -- for example, if you touch or squeeze the skin, it doesn't bounce back the way it usually does
- Urinating less often or having dark yellow urine
What to expect at your health care provider's office
Your health care provider will perform a physical examination, and will look for signs of dehydration.
Your health care provider will ask questions about your symptoms, such as:
- When did the vomiting begin? How long has it lasted? How often does it occur?
- Does it occur after you eat, or on an empty stomach?
- What other symptoms are present -- abdominal pain, fever, diarrhea, or headaches?
- Are you vomiting blood
- Are you vomiting anything that looks like coffee grounds?
- Are you vomiting undigested food?
- When was the last time you urinated?
Other questions you may be asked include:
- Have you been losing weight?
- Have you been traveling? Where?
- What medications do you take?
- Did other people who ate at the same place as you have the same symptoms?
- Are you pregnant or could you be pregnant?
The diagnostic tests may be performed:
Depending on the cause and how much extra fluids you need, you may have to stay in the hospital or clinic for a period of time. You may need fluids given through your veins (intravenous or IV).

10 Tips for Parents of Prospective College Students
1. Choosing a Career/Choosing a Major
Ultimately, your son or daughter should make the choice. Of course, you may want to mention factors to consider, such as job market demand, salary ranges, long-range opportunities, skills required, etc. Just because an occupation is "hot" now does not mean it will be equally in demand in 10 years or that your child has the aptitude or motivation for it.
2. Choosing to Double Major/Choosing a Major and Minor
Most employers do not place a premium on a double major. It usually requires an extra one or two semesters to obtain a second major and does not particularly enhance a student's marketability. Exceptions would be a second major or a major and minor chosen for a specific career, such as English and chemistry for technical writing, or a health policy major and business minor for hospital administration.
3. Grade Point Average (GPA)
Some students who get off to a rocky start eventually pull up their grades; however, this can be very difficult to do. Many employers stress the student's overall background: work experience, number of hours worked during the school year to finance college, leadership activities, etc. Encourage your son or daughter to make academics a high priority beginning with his or her freshman year. It is important to remember that it may take him or her a while to adjust to the rigorous academic demands of college.
4. Obtaining Marketable Skills
Most employers today put more emphasis on graduates' skills than on their academic majors. Encourage your son or daughter to develop strengths in at least two or three of the following areas:
- Computer skills (e.g., programming, word processing, spreadsheets, data base management, e-mail, Internet);
- Quantitative skills (e.g., accounting, statistics, economics);
- Communication skills (e.g., written and oral);
- Marketing/selling skills (e.g., sales, publicity, fundraising);
- Scientific skills (e.g., lab skills, scientific research);
- Foreign language skills (e.g., especially Spanish, Portuguese, Chinese, or Russian);
- Leadership skills (e.g., supervisory, extracurricular leadership roles, teamwork/team leader).
5. Leadership Activities
Many employers rate leadership activities even more highly than GPA. Students who were very active in high school activities may be less involved in college extracurricular activities. However, employers regard high school as "ancient history" for a college senior. It is more valuable for a student to be involved in a few meaningful leadership roles on campus than to be in a "laundry list" of many campus clubs.
You may want your son or daughter to work in his or her hometown every summer. However, the experience gained as a lifeguard or ice cream shop counter clerk does not compare to that which comes from an internship (paid or unpaid) in the career field that he or she aspires to enter. Future employers will seek graduates with relevant, real-world work experience. Some students have little to write about on a resume if their summers were spent in school, traveling, or working at low-level jobs. We strongly suggest that students seek career-related experience for their sophomore and junior summers even if they must live away from home or accept an unpaid internship. Students needing financial support can combine an unpaid internship with a paid job such as waiter/waitress, etc.
7. Graduating Early, Graduating Late
Some students graduate early through advanced placement credits, heavy course loads, and summer school courses. The advantages are lower educational expenses and the ability to start employment or graduate school earlier. The disadvantages may include the sacrifice of academic honors, work experience, and extracurricular and volunteer activities that may contribute to a student's maturity level and qualifications. Other students graduate late due to light course loads, academic difficulties, changing majors, poor academic advising, lack of direction, or reluctance to leave the cocoon of the college environment. Advantages to late graduation include the ability to improve grades with light class loads, extra time to change majors, the ability to take additional electives to improve marketability, and extra time to gain more career-related or leadership experience. Disadvantages to late graduation are increased college costs and possible disapproval of employers and graduate schools.
8. Planning for Graduate/Professional School
About 88 percent of the nation's college freshmen indicated in a recent survey that they plan to go to graduate or professional school, yet only about 24 percent do so within a year of completing their bachelor's degree. Students aspiring to graduate or professional school should: Be clear about the reasons they want to go on for further education; research the qualifications required for admission and be realistic about their chances of acceptance; and always have a "Plan B" or back-up plan in case they are not accepted. Students should discuss their interest in graduate or professional school well before their senior year with their academic adviser; the college's graduate or professional school adviser (e.g., the pre-law or pre-med adviser); and a college career adviser to obtain advice and guidance from three different perspectives.
9. Taking Time Off
Many students want to take time off after college graduation from college before attending graduate school or taking a career-related job. Future employers will want to know how the student has spent the intervening time. Do activities during this period demonstrate relevance to future career goals and/or a good work ethic? While short-term travel may be personally broadening, it does not increase a student's marketability to employers unless it is seen as career related. Therefore, the time off may result in a longer job search. For example, management trainee programs, which often begin shortly after graduation and hire large numbers of new graduates, may be filled by the time your child is ready to begin a job search.
10. Using the College Career Services Office
Students should begin using their campus career office in their freshman year. Virtually all career offices provide individual career counseling/advising, career planning workshops, internship assistance, and career fairs and programs. Your son or daughter should seek help early with choosing a career and preparing for it. Competition for good jobs, particularly in certain fields, is stiff. The career office can advise students about how to become a strong candidate for their field of interest.

Press Release: First Comprehensive National Study Finds Centers Safest Form of Childcare
Child care centers are much safer than all other forms of child care, according to a new national study.
Sociologists Julia Wrigley and Joanna Dreby of the City University of New York Graduate Center created a comprehensive database of child care failures, including fatalities, between 1985 and 2003. They found that child care is quite safe overall, and child care fatalities are rarer than outside of paid care. But the fatality rate for children who receive child care in private homes is sixteen times higher than the fatality rate for children in child care centers.
The study appears in the October issue of the American Sociological Review . It was funded by the Foundation for Child Development.
While more than 8 million children are in paid child care every day, until now little has been known about their safety. Wrigley and Dreby analyzed reports of 1,362 fatalities (among 4,356 caregiving failures) from 1985 to 2003. The fatality data was gathered from media reports, legal cases, and state records. Three forms of child care were investigated: child care centers, nannies working in children's homes, and family day care providers working in their own homes.
"While accidents can happen anywhere, child care centers are almost 100% protective against children's deaths by violence. They are much safer than arrangements in private homes," explains Wrigley.
Infants are by far the most vulnerable children in care. Their fatality rate from both accidents and violence is nearly seven times higher than that of children from one to four. Equally striking are differences in infant fatality rates across types of care. The infant fatality rate in the care of nannies or family day care providers is more than seven times higher than that in centers.
Why are centers the safest form of child care?
Wrigley and Dreby conclude that centers are the safest form of child care because they afford children multiple forms of protection. Most importantly, staff members do not work alone. They have others watching them and helping them cope with fussy infants or whining toddlers. This helps them maintain their emotional control. It also helps identify and remove unstable or volatile workers. Center teachers also have more training than most caregivers in private homes and they are supervised by professionally-trained directors. Finally, centers control access by outsiders more effectively to keep out people who might pose risks.
These protections help reduce risks of accidental deaths, such as suffocation and drowning. But they are especially important in preventing violent deaths. Not a single shaken baby fatality was found in a child care center, while 203 were reported in arrangements in private homes. The stress of infant crying, in particular, can drive caregivers to impulsive acts of violence. With little professional training, without supervisors or coworkers, and often paid very little for long hours of work, even some experienced caregivers can lose emotional control. Once children are past the toddler years, safety differences between centers and other forms of child care diminish.
Wrigley says, "Child care is quite safe overall, but it could be made safer. We need to recognize what a stressful and demanding job it is to look after young children. Improved safety will only come with more resources and closer regulation of care."
How can we improve child care safety?
A complete copy of the article, titled: "Fatalities and the Organization of Childcare," can be found beginning November 1 on the website of the American Sociological Association www.asanet.org which will also be linked from The Graduate Center's website www.gc.cuny.edu . Hard copies may be obtained from by contacting Johanna Ebner at the American Sociological Association, 1307 New York Avenue, NW, Suite 700, Washington, D.C. 20005.
While working on this research, Julia Wrigley was a Professor of Sociology at the CUNY Graduate Center, where she was recently appointed Acting Associate Provost. Her work focuses on social class and inequality. She is the author of Class Politics and Public Schools , on conflicts over the control and funding of Chicago's schools, and Other People's Children , on relations between middle-class parents and their children's caregivers. She edited Sociology of Education and chaired the ASA section on Children and Youth.
Joanna Dreby is a Ph.D. student in Sociology at the CUNY Graduate Center. Her research interests include child care, the sociology of children, gender and families and immigration/transnational communities. She recently spent a year in Mexico on a Fulbright doing research for her dissertation on parent-child separation in Mexican transnational families.
The Foundation for Child Development is a national, private philanthropy dedicated to the principle that all families should have the social and material resources to raise their children to be healthy, educated, and productive members of society. PK-3, the Foundation's signature focus, seeks to create a new beginning for public education from prekindergarten through third grade. For more information, visit the Foundation's website, http://www.fcd-us.org.
The Graduate Center is the doctorate-granting institution of The City University of New York. The only consortium of its kind in the nation, the school draws its faculty of more than 1,700 members mainly from the CUNY senior colleges. Established in 1961, The Graduate Center has grown to an enrollment of about 4,000 students in 32 doctoral programs and six master's degree programs in the humanities, social sciences, and sciences. The Graduate Center also houses 28 research centers and institutes, administers the CUNY Baccalaureate Program as well as a number of other university-wide academic programs, and offers a wide range of continuing education and cultural programs of interest to the general public.

Daily Planet's Ingram discusses prion disease 0
Discovery Channel's Daily Planet co-host Jay Ingram visits Grande Prairie today to offer behind-the-scenes details of a mysterious and contagious series of diseases.
The lecture takes place at the Grande Prairie Regional College at 7 p.m., where Ingram discusses fatal prion diseases.
"Here at this very microscopic level, strange things are happening and just now we are beginning to figure out what they are," he said.
The most well-known form of a prion disease is bovine spongiform encephalopathy (BSE), widely known as the mad cow disease.
Prion diseases spread when malformed proteins attach themselves to healthy tissue. Unlike other infectious ailments, they are incurable.
"It is a protein that has gone wrong," said Stefanie Czub, a scientist with the University of Calgary and the Canadian Food Inspection Agency who will be present at the lecture.
"For other infectious diseases we have a cure or the body heals itself quite efficiently.prion diseases, once infected, they are invariably fatal."
A prion disease of current concern to Western Canadians is chronic wasting disease (CWD), affecting deer and elk in southern Saskatchewan and Alberta. Unlike mad cow disease, which infects the animal's brain, spinal cord and central nervous system, chronic wasting disease spreads to several parts of the animal, and is even present in urine and saliva.
Animals infected become very thin, and can carry the disease for two years before these signs become evident.
Prion diseases can only be formally diagnosed by sampling infected tissue.
"With all these diseases, it takes quite a long time for the symptoms to show," Ingram said. "You could hunt and kill a deer and eat it, and it might have the chronic wasting disease prions in it."
"The ultimate diagnosis can only be done on a piece of tissue, not in blood," Czub said.
Twenty deer have been identified in Alberta with CWD since monitoring of the disease began in 2005. While the cause of mad cow disease is generally believed to be the use of recycled beef and bone meal material in livestock feed, which became a common practice in the 1980s, CWD's cause remains unknown.
"Nobody really knows," Ingram said. "It could be that an infected deer goes to a salt lick, licks it, and the prions are in the saliva."
Ingram said that the disease is currently not an issue for the Peace Country, but infected deer and elk are bringing it into southern Alberta as they travel along the valleys of the South Saskatchewan and Red Deer Rivers.
"If chronic wasting disease spreads far enough north, especially in Saskatchewan, that it intersects with the caribou migration routes, and if caribou are susceptible, then you've got a huge problem on your hands," Ingram said.
The medical community is taking a close look at CWD due to the similarities prion diseases have with the degenerative Alzheimer's, Parkinson's and Lou Gehrig's diseases.
"The way that they spread is somewhat similar," Ingram said. "In Alzheimer's and Parkinson's and Lou Gehrig's disease, you get an accumulation in the brain of junk basically; they're called plaques, these sort of dark deposits if you look at brain tissue after autopsy."
"They are all part of the so-called protein-misfolding diseases," Czub said. "One might be a very good model for the other, so we need to keep that in mind. Especially with this enormous increase in Alzheimer's in the future to be expected. One in three over the age of 65 is going to develop Alzheimer's disease in the next 10 years."
Hosted by the Alberta Prion Research Institute, Ingram's lecture is open to the public free of charge in the Collins Recital Hall, room L106 today at 7 p.m.

Intellectual knowledge appears to be innate and privy to the few, but in fact, access to information, development of intellectual work skills, time investment, and the maintenance of intellectual appearances are key to being perceived as an intellectual.
To make education more equitable, professors must go beyond knowledge transmission and instruct students in the concrete skills of knowledge acquisition and knowledge presentation. Instruction in intellectual skills-acquisition implies the breakdown of the traditional professor-student relationship and of the academic intellectual hierarchy and professors must learn to cope with the consequences of adopting new pedagogies. If we wish to share the secrets of our professions, how do we prepare our students for such a democratic approach and at the same time maintain our professional status?
The author, a professor of Spanish language and literature, presents strategies for democratizing education and demystifying intellectual work through the application of skills-based pedagogical methodologies to the teaching of literature. The implications that these strategies have for a new type of learning and the impact that they have on social stratification will also be discussed.

Beta Pictoris planet finally imaged?
21 November 2008
A team of French astronomers using ESO's Very Large Telescope have discovered an object located very close to the star Beta Pictoris, and which apparently lies inside its disc. With a projected distance from the star of only 8 times the Earth-Sun distance, this object is most likely the giant planet suspected from the peculiar shape of the disc and the previously observed infall of comets onto the star. It would then be the first image of a planet that is as close to its host star as Saturn is to the Sun.
The hot star Beta Pictoris is one of the best-known examples of stars surrounded by a dusty 'debris' disc. Debris discs are composed of dust resulting from collisions among larger bodies like planetary embryos or asteroids. They are a bigger version of the zodiacal dust in our Solar System. Its disc was the first to be imaged — as early as 1984 — and remains the best-studied system. Earlier observations showed a warp of the disc, a secondary inclined disc and infalling comets onto the star. "These are indirect, but tell-tale signs that strongly suggest the presence of a massive planet lying between 5 and 10 times the mean Earth-Sun distance from its host star," says team leader Anne-Marie Lagrange. "However, probing the very inner region of the disc, so close to the glowing star, is a most challenging task."
In 2003, the French team used the NAOS-CONICA instrument (or NACO ), mounted on one of the 8.2 m Unit Telescopes of ESO's Very Large Telescope (VLT), to benefit from both the high image quality provided by the Adaptive Optics system at infrared wavelengths and the good dynamics offered by the detector, in order to study the immediate surroundings of Beta Pictoris.
Recently, a member of the team re-analysed the data in a different way to seek the trace of a companion to the star. Infrared wavelengths are indeed very well suited for such searches. "For this, the real challenge is to identify and subtract as accurately as possible the bright stellar halo," explains Lagrange. "We were able to achieve this after a precise and drastic selection of the best images recorded during our observations."
The strategy proved very rewarding, as the astronomers were able to discern a feeble, point-like glow well inside the star's halo. To eliminate the possibility that this was an artefact and not a real object, a battery of tests was conducted and several members of the team, using three different methods, did the analysis independently, always with the same success. Moreover, the companion was also discovered in other data sets, further strengthening the team's conclusion: the companion is real.
"Our observations point to the presence of a giant planet, about 8 times as massive as Jupiter and with a projected distance from its star of about 8 times the Earth-Sun distance, which is about the distance of Saturn in our Solar System ," says Lagrange.
"We cannot yet rule out definitively, however, that the candidate companion could be a foreground or background object," cautions co-worker Gael Chauvin. "To eliminate this very small possibility, we will need to make new observations that confirm the nature of the discovery."
The team also dug into the archives of the Hubble Space Telescope but couldn't see anything, "while most possible foreground or background objects would have been detected", remarks another team member, David Ehrenreich.
The fact that the candidate companion lies in the plane of the disc also strongly implies that it is bound to the star and its proto-planetary disc.
"Moreover, the candidate companion has exactly the mass and distance from its host star needed to explain all the disc's properties. This is clearly another nail in the coffin of the false alarm hypothesis," adds Lagrange.
When confirmed, this candidate companion will be the closest planet from its star ever imaged. In particular, it will be located well inside the orbits of the outer planets of the Solar System. Several other planetary candidates have indeed been imaged, but they are all located further away from their host star: if located in the Solar System, they would lie close or beyond the orbit of the farthest planet, Neptune. The formation processes of these distant planets are likely to be quite different from those in our Solar System and in Beta Pictoris.
"Direct imaging of extrasolar planets is necessary to test the various models of formation and evolution of planetary systems. But such observations are only beginning. Limited today to giant planets around young stars, they will in the future extend to the detection of cooler and older planets, with the forthcoming instruments on the VLT and on the next generation of optical telescopes," concludes team member Daniel Rouan.
Only 12 million years old, the 'baby star' Beta Pictoris is located about 70 light-years away towards the constellation Pictor (the Painter).
NACO is one of the instruments on ESO's VLT that make use of Adaptive Optics (AO). Such systems work by means of a computer-controlled deformable mirror that counteracts the image distortion induced by atmospheric turbulence (see e.g. ESO Press Release 25/01).
The astronomers can only see the projected separation between the star and the planet (that is, the separation projected on the plane of the sky).

Many policy problems (from road congestion to water and electricity shortages) can be greatly improved through the proper application of a simple concept–pricing. In this USA Today article, Reason's Bob Poole explains how to apply pricing to air traffic control: By charging planes to use the most congested airports and airways, the system would give its customers economic incentives to reschedule flight times or choose less-congested airports without such charges. That easing of demand would provide breathing room to address the looming shortfalls in air-traffic-control capacity. All sorts of new technology can increase this capacity, both cross-country and on the approaches to airport runways. "Synthetic vision" systems can permit pilots to land at socked-in airports at nearly the same rate as in clear weather. So the air-traffic system need not break down just because Chicago has a bad-weather day. Other advanced technologies can reduce the size of the protective bubble needed around planes en route to keep them safely separated.

How many times did you hear that today? Probably a lot. But why are adults so hung up on hand washing? Why are they so in love with lather?
Washing your hands is the best way to stop germs from spreading. Think about all of the things that you touched today — from the telephone to the toilet. Maybe you blew your nose in a tissue and then went outside to dig around the dirt.
Whatever you did today, you came into contact with germs. It's easy for a germ on your hand to end up in your mouth. Think about how many foods you eat with your hands.
You can't wear rubber gloves all day long, but you can wash your hands so those germs don't get a chance to make you or someone else sick. When germs go down the drain, they can't make anyone sick.
So when are the best times to wash your hands?
when your hands are dirty
before eating or touching food (like if you're helping cook or bake, for example)
before and after visiting a sick relative or friend
Now you have the when and the why of hand washing. But did you know that a lot of people don't know how to get their paws perfectly clean? The next time you're told to step up to the sink and scrub up, remember these handy hints:
Use warm water (not cold or hot) when you wash your hands.
Use whatever soap you like. Some soaps come in cool shapes and colors or smell nice, but whatever kind gets you scrubbing is the kind you should use. Antibacterial soaps are OK to use, but regular soap works fine.
Work up some lather on both sides of your hands, your wrists, and between your fingers. Don't forget to wash around your nails. This is one place germs like to hide. Wash for about 10 to 15 seconds — about how long it takes to sing "Happy Birthday." (Sing it quickly two times or just once if you go nice and slow.)

A Box of Universe
Watch the cosmos evolve in a cube one billion light-years wide
Isaac Newton’s universe was a cozy, tidy place. Gathered around the sun were six planets, a handful of moons and the occasional comet, all moving against a backdrop of stationary stars. Newton provided us with the mathematical tools needed to compute the motions of these bodies. Given initial positions and velocities, we can calculate the forces acting on each object, using Newton’s law of universal gravitation. From the forces we can determine accelerations, and then update the positions and velocities for the next round of calculations. This scheme of computation is known as the n-body method. Perhaps Newton himself could have put it to work if he had had suitable computing machinery.
Today we have the computers. On the other hand, our universe is far larger and more intricate than Newton’s. Now the solar system is merely a speck in a spiral galaxy of several hundred billion stars. Our galaxy drifts among billions of others, which form clusters and superclusters and a whole hierarchy of structures extending as far as the eye (and the telescope) can see. Those objects are getting farther away all the time because the universe is expanding, and moreover the expansion is accelerating. Strangest of all, the luminous matter of the galaxies—everything we see shining in the night sky—makes up less than one-half of 1 percent of what’s out there. Most of the universe is unseen and unidentified stuff known only as “dark matter” and “dark energy.”
Given this profound change in the nature and the scale of the known universe, I find it remarkable that computer simulations of cosmic evolution can still rely on n-body algorithms rooted in the principles of Newtonian mechanics. The same techniques that predict planetary motions here at home in the solar system also describe the gravitational process that assembles thousands of galaxies into filaments a hundred million light-years long.
A major new series of cosmological simulations is now beginning to release its findings. The project, known as Bolshoi, is led by Anatoly Klypin of New Mexico State University and Joel Primack of the University of California, Santa Cruz. “Bolshoi” is Russian for “big” or “grand,” and the name is apt: This is a large-scale computational project, consuming six million CPU hours and producing a hundred terabytes of data. And yet, when you ponder the vast sweep of space and time being modeled, it seems a marvel that so much universe can be squeezed into such a small box.

The Burden of Kidney Failure
Each year in the United States, more than 100,000 people are diagnosed with kidney failure, a serious condition in which the kidneys fail to rid the body of wastes.1 Kidney failure is the final stage of chronic kidney disease (CKD).
Diabetes is the most common cause of kidney failure, accounting for nearly 44 percent of new cases.1 Even when diabetes is controlled, the disease can lead to CKD and kidney failure. Most people with diabetes do not develop CKD that is severe enough to progress to kidney failure. Nearly 24 million people in the United States have diabetes, 2 and nearly 180,000 people are living with kidney failure as a result of diabetes.1
People with kidney failure undergo either dialysis, an artificial blood-cleaning process, or transplantation to receive a healthy kidney from a donor. Most U.S. citizens who develop kidney failure are eligible for federally funded care. In 2005, care for patients with kidney failure cost the United States nearly $32 billion.1
African Americans, American Indians, and Hispanics/Latinos develop diabetes, CKD, and kidney failure at rates higher than Caucasians. Scientists have not been able to explain these higher rates. Nor can they explain fully the interplay of factors leading to kidney disease of diabetes—factors including heredity, diet, and other medical conditions, such as high blood pressure. They have found that high blood pressure and high levels of blood glucose increase the risk that a person with diabetes will progress to kidney failure.

The Course of Kidney Disease
Diabetic kidney disease takes many years to develop. In some people, the filtering function of the kidneys is actually higher than normal in the first few years of their diabetes.
Over several years, people who are developing kidney disease will have small amounts of the blood protein albumin begin to leak into their urine. This first stage of CKD is called microalbuminuria. The kidney's filtration function usually remains normal during this period.
As the disease progresses, more albumin leaks into the urine. This stage may be called macroalbuminuria or proteinuria. As the amount of albumin in the urine increases, the kidneys' filtering function usually begins to drop. The body retains various wastes as filtration falls. As kidney damage develops, blood pressure often rises as well.
Overall, kidney damage rarely occurs in the first 10 years of diabetes, and usually 15 to 25 years will pass before kidney failure occurs. For people who live with diabetes for more than 25 years without any signs of kidney failure, the risk of ever developing it decreases.
Diagnosis of CKD
People with diabetes should be screened regularly for kidney disease. The two key markers for kidney disease are eGFR and urine albumin.
eGFR. eGFR stands for estimated glomerular filtration rate. Each kidney contains about 1 million tiny filters made up of blood vessels. These filters are called glomeruli. Kidney function can be checked by estimating how much blood the glomeruli filter in a minute. The calculation of eGFR is based on the amount of creatinine, a waste product, found in a blood sample. As the level of creatinine goes up, the eGFR goes down.
Kidney disease is present when eGFR is less than 60 milliliters per minute.
The American Diabetes Association (ADA) and the National Institutes of Health (NIH) recommend that eGFR be calculated from serum creatinine at least once a year in all people with diabetes.
Urine albumin. Urine albumin is measured by comparing the amount of albumin to the amount of creatinine in a single urine sample. When the kidneys are healthy, the urine will contain large amounts of creatinine but almost no albumin. Even a small increase in the ratio of albumin to creatinine is a sign of kidney damage.
Kidney disease is present when urine contains more than 30 milligrams of albumin per gram of creatinine, with or without decreased eGFR.
The ADA and the NIH recommend annual assessment of urine albumin excretion to assess kidney damage in all people with type 2 diabetes and people who have had type 1 diabetes for 5 years or more.
If kidney disease is detected, it should be addressed as part of a comprehensive approach to the treatment of diabetes.
Effects of High Blood Pressure
High blood pressure, or hypertension, is a major factor in the development of kidney problems in people with diabetes. Both a family history of hypertension and the presence of hypertension appear to increase chances of developing kidney disease. Hypertension also accelerates the progress of kidney disease when it already exists.
Blood pressure is recorded using two numbers. The first number is called the systolic pressure, and it represents the pressure in the arteries as the heart beats. The second number is called the diastolic pressure, and it represents the pressure between heartbeats. In the past, hypertension was defined as blood pressure higher than 140/90, said as "140 over 90."
The ADA and the National Heart, Lung, and Blood Institute recommend that people with diabetes keep their blood pressure below 130/80.
Hypertension can be seen not only as a cause of kidney disease but also as a result of damage created by the disease. As kidney disease progresses, physical changes in the kidneys lead to increased blood pressure. Therefore, a dangerous spiral, involving rising blood pressure and factors that raise blood pressure, occurs. Early detection and treatment of even mild hypertension are essential for people with diabetes.
Preventing and Slowing Kidney Disease
Blood Pressure Medicines
Scientists have made great progress in developing methods that slow the onset and progression of kidney disease in people with diabetes. Drugs used to lower blood pressure can slow the progression of kidney disease significantly. Two types of drugs, angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), have proven effective in slowing the progression of kidney disease. Many people require two or more drugs to control their blood pressure. In addition to an ACE inhibitor or an ARB, a diuretic can also be useful. Beta blockers, calcium channel blockers, and other blood pressure drugs may also be needed.
An example of an effective ACE inhibitor is lisinopril (Prinivil, Zestril), which doctors commonly prescribe for treating kidney disease of diabetes. The benefits of lisinopril extend beyond its ability to lower blood pressure: it may directly protect the kidneys' glomeruli. ACE inhibitors have lowered proteinuria and slowed deterioration even in people with diabetes who did not have high blood pressure.
An example of an effective ARB is losartan (Cozaar), which has also been shown to protect kidney function and lower the risk of cardiovascular events.
Any medicine that helps patients achieve a blood pressure target of 130/80 or lower provides benefits. Patients with even mild hypertension or persistent microalbuminuria should consult a health care provider about the use of antihypertensive medicines.
In people with diabetes, excessive consumption of protein may be harmful. Experts recommend that people with kidney disease of diabetes consume the recommended dietary allowance for protein, but avoid high-protein diets. For people with greatly reduced kidney function, a diet containing reduced amounts of protein may help delay the onset of kidney failure. Anyone following a reduced-protein diet should work with a dietitian to ensure adequate nutrition.
Intensive Management of Blood Glucose
Antihypertensive drugs and low-protein diets can slow CKD. A third treatment, known as intensive management of blood glucose or glycemic control, has shown great promise for people with diabetes, especially for those in the early stages of CKD.
The human body normally converts food to glucose, the simple sugar that is the main source of energy for the body's cells. To enter cells, glucose needs the help of insulin, a hormone produced by the pancreas. When a person does not make enough insulin, or the body does not respond to the insulin that is present, the body cannot process glucose, and it builds up in the bloodstream. High levels of glucose in the blood lead to a diagnosis of diabetes.
Intensive management of blood glucose is a treatment regimen that aims to keep blood glucose levels close to normal. The regimen includes testing blood glucose frequently, administering insulin throughout the day on the basis of food intake and physical activity, following a diet and activity plan, and consulting a health care team regularly. Some people use an insulin pump to supply insulin throughout the day.
A number of studies have pointed to the beneficial effects of intensive management of blood glucose. In the Diabetes Control and Complications Trial supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), researchers found a 50 percent decrease in both development and progression of early diabetic kidney disease in participants who followed an intensive regimen for controlling blood glucose levels. The intensively managed patients had average blood glucose levels of 150 milligrams per deciliter-about 80 milligrams per deciliter lower than the levels observed in the conventionally managed patients. The United Kingdom Prospective Diabetes Study, conducted from 1976 to 1997, showed conclusively that, in people with improved blood glucose control, the risk of early kidney disease was reduced by a third. Additional studies conducted over the past decades have clearly established that any program resulting in sustained lowering of blood glucose levels will be beneficial to patients in the early stages of CKD.
Dialysis and Transplantation
When people with diabetes experience kidney failure, they must undergo either dialysis or a kidney transplant. As recently as the 1970s, medical experts commonly excluded people with diabetes from dialysis and transplantation, in part because the experts felt damage caused by diabetes would offset benefits of the treatments. Today, because of better control of diabetes and improved rates of survival following treatment, doctors do not hesitate to offer dialysis and kidney transplantation to people with diabetes.
Currently, the survival of kidneys transplanted into people with diabetes is about the same as the survival of transplants in people without diabetes. Dialysis for people with diabetes also works well in the short run. Even so, people with diabetes who receive transplants or dialysis experience higher morbidity and mortality because of coexisting complications of diabetes-such as damage to the heart, eyes, and nerves.
Good Care Makes a Difference
People with diabetes should
- have their health care provider measure their A1C level at least twice a year. The test provides a weighted average of their blood glucose level for the previous 3 months. They should aim to keep it at less than 7 percent.
- work with their health care provider regarding insulin injections, medicines, meal planning, physical activity, and blood glucose monitoring.
- have their blood pressure checked several times a year. If blood pressure is high, they should follow their health care provider's plan for keeping it near normal levels. They should aim to keep it at less than 130/80.
- ask their health care provider whether they might benefit from taking an ACE inhibitor or ARB.
- ask their health care provider to measure their eGFR at least once a year to learn how well their kidneys are working.
- ask their health care provider to measure the amount of protein in their urine at least once a year to check for kidney damage.
- ask their health care provider whether they should reduce the amount of protein in their diet and ask for a referral to see a registered dietitian to help with meal planning.
Points to Remember
- Diabetes is the leading cause of chronic kidney disease (CKD) and kidney failure in the United States.
- People with diabetes should be screened regularly for kidney disease. The two key markers for kidney disease are estimated glomerular filtration rate (eGFR) and urine albumin.
- Drugs used to lower blood pressure can slow the progression of kidney disease significantly. Two types of drugs, angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), have proven effective in slowing the progression of kidney disease.
- In people with diabetes, excessive consumption of protein may be harmful.
- Intensive management of blood glucose has shown great promise for people with diabetes, especially for those in the early stages of CKD.
Hope through Research
The number of people with diabetes is growing. As a result, the number of people with kidney failure caused by diabetes is also growing. Some experts predict that diabetes soon might account for half the cases of kidney failure. In light of the increasing illness and death related to diabetes and kidney failure, patients, researchers, and health care professionals will continue to benefit by addressing the relationship between the two diseases. The NIDDK is a leader in supporting research in this area.
Several areas of research supported by the NIDDK hold great potential. Discovery of ways to predict who will develop kidney disease may lead to greater prevention, as people with diabetes who learn they are at risk institute strategies such as intensive management of blood glucose and blood pressure control.
Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research. For information about current studies, visit www.ClinicalTrials.gov.

Understanding SQL's underlying theory is the best way to guarantee that your SQL code is correct and your database schema is robust and maintainable. On the other hand, if you're not well versed in the theory, you can fall into several traps. In SQL and Relational Theory, author C.J. Date demonstrates how you can apply relational theory directly to your use of SQL. With numerous examples and clear explanations of the reasoning behind them, you'll learn how to deal with common SQL dilemmas, such as:
- Should database access granted be through views instead of base tables?
- Nulls in your database are causing you to get wrong answers. Why? What can you do about it?
- Could you write an SQL query to find employees who have never been in the same department for more than six months at a time?
- SQL supports "quantified comparisons," but they're better avoided. Why? How do you avoid them?
- Constraints are crucially important, but most SQL products don't support them properly. What can you do to resolve this situation?
Database theory and practice have evolved since Edgar Codd originally defined the relational model back in 1969. Independent of any SQL products, SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL will benefit from the many insights in this book.

World War I (abbreviated as WW-I, WWI, or WW1), also known as the First World War, the Great War, and the War to End All Wars, was a global military conflict that embroiled most of the world's great powers, assembled in two opposing alliances: the Triple Entente and the Triple Alliance. Over 70 million military personnel were mobilized in one of the largest wars in history. The main combatants descended into a state of total war, pumping their entire scientific and industrial capabilities into the war effort. Over 15 million people were killed, making it one of the deadliest conflicts in history.
The immediate or proximate cause of war was the assassination on 28 June 1914 of Archduke Franz Ferdinand of Austria, heir to the Austro-Hungarian throne, by Gavrilo Princip, a Serbian nationalist. Austria-Hungary's resulting demands against the Kingdom of Serbia activated a sequence of alliances. Within weeks the major European powers were at war; their global empires meant that the conflict soon spread worldwide.
By the war's end, four major imperial powers—Germany, Russia, Austria-Hungary, and the Ottoman Empire—had been militarily and politically defeated, with the latter two ceasing to exist as autonomous entities. The revolutionized Soviet Union emerged from the Russian Empire, while the map of central Europe was completely redrawn into numerous smaller states. The League of Nations was formed in the hope of preventing another such conflict. The European nationalism spawned by the war, the repercussions of Germany's defeat, and the Treaty of Versailles would eventually lead to the beginning of World War II in 1939.

This section provides primary sources that document how Indian and European men and one English and one Indian woman have described the practice of sati, or the self-immolation of Hindu widows.
Although they are all critical of self-immolation, Francois Bernier, Fanny Parks, Lord William Bentinck, and Rev. England present four different European perspectives on the practice of sati and what it represents about Indian culture in general, and the Hindu religion and Hindu women in particular. They also indicate increasing negativism in European attitudes toward India and the Hindu religion in general. It would be useful to compare the attitudes of Bentinck and England as representing the secular and sacred aspects of British criticism of sati. A comparison of Bentinck’s minute with the subsequent legislation also reveals differences in tone between private and public documents of colonial officials. Finally, a comparison between the Fanny Parks and the three men should raise discussion on whether or not the gender and social status of the writer made any difference in his or her appraisal of the practice of self-immolation.
The three sources by Indian men and one by an Indian woman illustrate the diversity of their attitudes toward sati. The Marathi source illuminates the material concerns of relatives of the Hindu widow who is urged to adopt a son, so as to keep a potentially lucrative office within the extended family. These men are willing to undertake intense and delicate negotiations to secure a suitably related male child who could be adopted. This letter also documents that adoption was a legitimate practice among Hindus, and that Hindu women as well as men could adopt an heir. Ram Mohan Roy’s argument illustrates a rationalist effort to reform Hindu customs with the assistance of British legislation. Roy illustrates one of the many ways in which Indians collaborate with British political power in order to secure change within Indian society. He also enabled the British to counter the arguments of orthodox Hindus about the scriptural basis for the legitimacy of self-immolation of Hindu widows. The petition of the orthodox Hindu community in Calcutta, the capital of the Company’s territories in India, documents an early effort of Indians to keep the British colonial power from legislating on matters pertaining to the private sphere of Indian family life. Finally, Pandita Ramabai reflects the ways in which ancient Hindu scriptures and their interpretation continued to dominate debate. Students should consider how Ramabai’s effort to raise funds for her future work among child widows in India might have influenced her discussion of sati.
Two key issues should be emphasized. First, both Indian supporters and European and Indian opponents of the practice of self-immolation argue their positions on the bodies of Hindu women, and all the men involved appeal to Hindu scriptures to legitimate their support or opposition. Second, the voices of Indian women were filtered through the sieve of Indian and European men and a very few British women until the late 19th century.
- How do the written and visual sources portray the Hindu women who commit self-immolation? Possible aspects range from physical appearance and age, motivation, evidence of physical pain (that even the most devoted woman must suffer while burning to death), to any evidence of the agency or autonomy of the Hindu widow in deciding to commit sati. Are any differences discernible, and if so, do they seem related to gender or nationality of the observer or time period in which they were observed?
- How are the brahman priests who preside at the self-immolation portrayed in Indian and European sources? What might account for any similarities and differences?
- What reasons are used to deter Hindu widows from committing sati? What do these reasons reveal about the nature of family life in India and the relationships between men and women?
- What do the reasons that orthodox Hindus provide to European observers and to Indian reformers reveal about the significance of sati for the practice of the Hindu religion? What do their arguments reveal about orthodox Hindu attitudes toward women and the family?
- How are Hindu scriptures used in various ways in the debates before and after the prohibition of sati?
- What is the tone of the petition from 800 Hindus to their British governor? Whom do they claim to represent? What is their justification for the ritual of self-immolation? What is their attitude toward the Mughal empire whose Muslim rulers had preceded the British? What is their characterization of the petitioners toward those Hindus who support the prohibition on sati? How do the petitioners envision the proper relationship between the state and the practice of religion among its subjects?
- Who or what factors do European observers, British officials, and Indian opponents of sati hold to be responsible for the continuance of the practice of sati?
- What were the reasons that widows gave for committing sati? Were they religious, social or material motives? What is the evidence that the widows were voluntarily committing sati before 1829? What reasons did the opponents of sati give for the decisions of widows to commit self-immolation? What reasons did opponents give for widows who tried to escape from their husbands’ pyres?
- What are the reasons that Lord Bentinck and his Executive Council cite for their decision to declare the practice of sati illegal? Are the arguments similar to or different from his arguments in his minute a month earlier? What do these reasons reveal about British attitudes toward their role or mission in India? Do they use any of the arguments cited by Ram Mohan Roy or Pandita Ramabai?
- What do these sources, both those who oppose sati and those who advocate it, reveal about their attitudes to the Hindu religion in particular and Indian culture in general?

Inflammation Key to the Asthma-Sinus Connection
People with asthma frequently experience problems with their sinuses. And more than half of those who have chronic sinusitis also suffer from asthma.
Is there a connection? Each condition is marked by inflammation, which is to blame for both the symptoms of asthma—cough, chest tightness, shortness of breath, and wheezing—and sinusitis. Researchers speculate inflammation in the lungs or sinuses affects both. As a result, people with lung symptoms likely will eventually get symptoms in the nose, and vice versa. Plus, sinusitis can trigger asthma attacks.
What is sinusitis?
Sinusitis occurs when air-filled spaces behind the nose, forehead, cheeks, and eyes become inflamed and blocked with mucus. Often, infection results.
Symptoms usually occur after a cold that fails to improve or gets worse after five to seven days. They include:
People with asthma who experience sinus problems should talk with their doctor about treatment. Studies show that resolving sinusitis often improves asthma and decreases the need for asthma medication.
How you can protect yourself
Those with asthma need to be vigilant about colds and the flu. Viral respiratory infections often worsen asthma. Some prevention tips:
Avoid smoke and pollution.
Drink plenty of fluids.
Take decongestants for upper respiratory infections.
Get help for allergies.
Use a humidifier to increase moisture in nose and sinuses.

One-Legged (Single Limb) Stance Test
The One-Legged Stance Test (OLST)1,2 is a simple, easy and effective method to screen for balance impairments in the older adult population.
You may be asking yourself, "how can standing on one leg provide you with any information about balance, after all, we do not go around for extended periods of time standing on one leg?"
True, as a rule we are a dynamic people, always moving, our world always in motion, but there are instances were we do need to maintain single limb support. The most obvious times are when we are performing our everyday functional activities.
Stepping into a bath tub or up onto a curb would be difficult, if not impossible to do without the ability to maintain single limb support for a given amount of time. The ability to switch from two- to one-leg standing is required to perform turns, climb stairs and dress.
As we know, the gait cycle requires a certain amount of single limb support in order to be able to progress ourselves along in a normal pattern. When the dynamics of the cycle are disrupted, loss of balance leading to falls may occur.
This is especially true in older individuals whose gait cycle is altered due to normal and potentially abnormal changes that occur as a result of aging.
The One-Legged Stance Test measures postural stability (i.e., balance) and is more difficult to perform due to the narrow base of support required to do the test. Along with five other tests of balance and mobility, reliability of the One-Legged Stance Test was examined for 45 healthy females 55 to 71 years old and found to have "good" intraclass correlations coefficients (ICC range = .95 to .099). Within raters ICC ranged from 0.73 to 0.93.3
To perform the test, the patient is instructed to stand on one leg without support of the upper extremities or bracing of the unweighted leg against the stance leg. The patient begins the test with the eyes open, practicing once or twice on each side with his gaze fixed straight ahead.
The patient is then instructed to close his eyes and maintain balance for up to 30 seconds.1
The number of seconds that the patient/client is able to maintain this position is recorded. Termination or a fail test is recorded if 1) the foot touches the support leg; 2) hopping occurs; 3) the foot touches the floor, or 4) the arms touch something for support.
Normal ranges with eyes open are: 60-69 yrs/22.5 ± 8.6s, 70-79 yrs/14.2 ± 9.3s. Normal ranges for eyes closed are: 60-69 yrs/10.2 ± 8.6s, 70-79 yrs/4.3 ± 3.0s.4 Briggs and colleagues reported balance times on the One-Legged Stance Test in females age 60 to 86 years for dominant and nondominant legs.
Given the results of this data, there appears to be some difference in whether individuals use their dominant versus their nondominant leg in the youngest and oldest age groups.
When using this test, having patients choose what leg they would like to stand on would be appropriate as you want to record their "best" performance.
It has been reported in the literature that individuals increase their chances of sustaining an injury due to a fall by two times if they are unable to perform a One-Legged Stance Test for five seconds.5 Other studies utilizing the One-Legged Stance Test have been conducted in older adults to assess static balance after strength training,6 performance of activities of daily living and platform sway tests.7
Interestingly, subscales of other balance measures such as the Tinetti Performance Oriented Mobility Assessment8 and Berg Balance Scale9 utilize unsupported single limb stance times of 10 seconds and 5 seconds respectively, for older individuals to be considered to have "normal" balance.
Thirty percent to 60 percent of community-dwelling elderly individuals fall each year, with many experiencing multiple falls.10 Because falls are the leading cause of injury-related deaths in older adults and a significant cause of disability in this population, prevention of falls and subsequent injuries is a worthwhile endeavor.11
The One-Legged Stance Test can be used as a quick, reliable and easy way for clinicians to screen their patients/clients for fall risks and is easily incorporated into a comprehensive functional evaluation for older adults.

APTA Encouraged by Cap Exceptions
New process grants automatic exceptions to beneficiaries needing care the most
Calling it "a good first step toward ensuring that Medicare beneficiaries continue to have coverage for the physical therapy they need," Ben F Massey, Jr, PT, MA, president of the American Physical Therapy Association (APTA), expressed optimism that the new exceptions process will allow a significant number of Medicare patients to receive services exceeding the $1,740 annual financial cap on Medicare therapy coverage. The new procedure, authorized by Congress in the recently enacted Deficit Reduction Act (PL 109-171), will be available to Medicare beneficiaries on March 13 under rules released this week by the Centers for Medicare and Medicaid Services (CMS).
"APTA is encouraged by the new therapy cap exceptions process," Massey said. "CMS has made a good effort to ensure that Medicare beneficiaries who need the most care are not harmed by an arbitrary cap."
As APTA recommended, the process includes automatic exceptions and also grants exceptions to beneficiaries who are receiving both physical therapy and speech language pathology (the services are currently combined under one $1,740 cap).
"We have yet to see how well Medicare contractors will be able to implement and apply this process. Even if it works well, Congress only authorized this new process through 2006. Congress must address this issue again this year, and we are confident that this experience will demonstrate to legislators that they must completely repeal the caps and provide a more permanent solution for Medicare beneficiaries needing physical therapy," Massey continued.
The therapy caps went into effect on Jan. 1, 2006, limiting Medicare coverage on outpatient rehabilitation services to $1,740 for physical therapy and speech therapy combined and $1,740 for occupational therapy.
The American Physical Therapy Association is a national professional organization representing more than 65,000 members. Its goal is to foster advancements in physical therapy practice, research and education.
New Mouthwash Helps With Pain
Doctors in Italy are studying whether a new type of mouthwash will help alleviate pain for patients suffering from head and neck cancer who were treated with radiation therapy, according to a new study (International Journal of Radiation Oncology*Biology*Physics, Feb. 1, 2006).
Fifty patients, suffering from various forms of head and neck cancer and who received radiation therapy, were observed during the course of their radiation treatment. Mucositis, or inflammation of the mucous membrane in the mouth, is the most common side effect yet no additional therapy has been identified that successfully reduces the pain.
This study sought to discover if a mouthwash made from the local anesthetic tetracaine was able to alleviate the discomfort associated with head and neck cancer and if there would be any negative side effects of the mouthwash. The doctors chose to concoct a tetracaine-based mouthwash instead of a lidocaine-based version because it was found to be four times more effective, worked faster and produced a prolonged relief.
The tetracaine was administered by a mouthwash approximately 30 minutes before and after meals, or roughly six times a day. Relief of oral pain was reported in 48 of the 50 patients. Sixteen patients reported that the mouthwash had an unpleasant taste or altered the taste of their food.

A view can become a page or a block. There is no difference in work between a page and a block. A page needs a path to display the page. A block is assigned to a region to display the page. There might be a few seconds different to set them up. After that, you can blocks in far more ways than usually shown in tutorials.
Blocks have their uses including constructing complex pages. The content of a page is usually the content of a node in the content region. A view replaces the node to display a list or some other small variation of content.
Next you are asked to make the view more complicated. You scratch your head. What you really need is a collection of views displaying different content. You could use panels and a bunch of other complex approaches. Think about the format again.
If you want a list of different views. You can make each one a block then place them one after the other down the page. Consider a shop.
A shop might list the top selling product in each category with a view sorted by category. The marketing manager then asks for the categories in a different order. The CEO wants some categories to list the top three. The product manager wants one category to list only one product but all the colours for the product.
You could make each category a separate view with each view in a block. Each view can have different criteria. You can give your CEO, sales manager, and marketing manager access to the block admin page and let them fight over the sequence of the blocks.
What method do you use to determine when to use multiple views?
Use the one view when you list data one set of data. Use multiple views when people want different data selection. For example, some product categories have colours but not all product categories. Some product categories have multiple packs but not all product categories.
If the one list has to be by category then colour or pack size and all the products use the same content type, you could use one view to sort by category then colour then pack size. There will be no overlap or conflict or missing data.
The same list becomes more complicated when each product category has a different content type and each content type has a different set of attributes. You might be able to product one list in one view but it will be sensitive to change and management will want change. Start with two views or more views stacked as blocks to form one list.
Another example is a book shop where novels have different descriptions and content types compared to other books. Cook books may have a special content type to allow listing by food type, country, major ingredients, and the reality television show paying for the cook book.
If the data is exactly the same for each view but the display is different, consider multiple displays on one view. The technique is described in another page. you make the first view a page to list the data and validate your data selection. You then add some displays to create the blocks. Each display might vary by as little as selecting a different content type.
Top ten lists are popular and soon take up too much space. People start talking about variations. Perhaps the top three items, including teasers, followed by the next seven without teasers.

The government's human rights record remained poor. Although there were no reports that the government or its agents committed politically motivated killings, security forces committed extrajudicial killings and acted with impunity. There was little political will to address the failure by government authorities to adhere to the rule of law. Detainees were abused, often to extract confessions, and prison conditions were harsh. Human rights monitors reported arbitrary arrests and prolonged pretrial detention, underscoring a weak judiciary and denial of the right to a fair trial. Land disputes and forced evictions, often accompanied by violence, were a continuing problem. The government restricted freedom of speech and the press through the use of defamation and disinformation suits, controlled or influenced the content of television and radio broadcasts, and at times interfered with freedom of assembly. Corruption was endemic and extended throughout all segments of society, including the executive, legislative, and judicial branches of government. Domestic violence and child abuse occurred, education of children was inadequate, and trafficking in women and children persisted. The government offered little assistance to persons with disabilities. Antiunion activity by employers and weak enforcement of labor laws continued, and child labor remained a problem. In a positive turn, on June 12, the Extraordinary Chambers of the Courts in Cambodia for the Prosecution of Crimes Committed during the Period of Democratic Kampuchea adopted its internal rules to begin prosecuting senior leaders of the Khmer Rouge regime and those most responsible for committing serious crimes. On July 31, the ECCC charged Kaing Guek Eav, alias Duch, with crimes against humanity and subsequently charged four other senior officials; at year's end all were in detention awaiting trial. In addition, on December 10, the government permitted a Human Rights Day march of 500 human rights activists, monks, and other persons and rally of an estimated 2,500 persons in Phnom Penh. RESPECT FOR HUMAN RIGHTS Section 1 Respect for the Integrity of the Person, Including Freedom From: a. Arbitrary or Unlawful Deprivation of Life There were no reports that the government or its agents committed politically motivated killings. However, human rights nongovernmental organizations (NGOs) reported that extrajudicial killings continued to occur. The Cambodian Human Rights and Development Association (ADHOC) recorded 53 cases of extrajudicial killings, 14 of which were committed by police, nine by soldiers, six by fishery officials, and the remaining 24 by unidentified government forces. Police arrested perpetrators in four cases. Political activists continued to be the victims of killings. On February 27, Eang Sok Thoeurn, a Khmer Kampuchea Krom monk, was found dead with his throat cut in the Tronum Chhroeung Monastery in Kandal Province. The deceased monk was discovered the morning after he participated in a demonstration in front of the Vietnamese embassy in Phnom Penh for the rights of Khmer Kampuchea Krom persons living in Vietnam. Police quickly declared the death a suicide and disposed of the body without further investigation. NGOs and Khmer Kampuchea Krom groups suspected the killing was politically motivated. Active members of political parties were killed during the year, but NGOs and police could not confirm their deaths were politically motivated. On February 14, three unidentified persons killed Sam Rainsy Party (SRP) activist Chea Sovin, spouse of an SRP candidate for the April commune council elections in Battambang Province. On July 27, three unidentified persons shot and killed Kleb Un, SRP commune‑level vice party chairperson in Banteay Meanchey Province. A local police chief reported that the perpetrators fled without robbing the victim or taking anything from the scene. Police arrested one suspect in the case but released him after questioning. In both killings, police stated that investigations continued. On April 4, police officer Siv Soeun allegedly shot and killed a person he claimed was illegally fishing on private property in the Kompong Siem District of Kampong Cham Province. The victim's family filed a complaint against the police officer but later withdrew the complaint after Siv Soeun allegedly paid the family $3,000 (12 million riel) in compensation. At year's end Siv Soeun had not been charged or arrested. On November 15, during the eviction of squatters from state land in Choam Ksan commune, Preah Vihear Province, unidentified government forces killed two villagers who protested the eviction. Approximately 150 police, military police, and soldiers evicted 317 families. There was no official investigation into the killings. Police arrested 18 of the squatters, including a deputy governor, on charges of encroachment on state land. The 18 villagers were imprisoned and awaited trial at year's end. In June the Prey Veng Provincial Court sentenced one suspect in the November 2006 killing of SRP activist Man Meth to 10 years in prison and two others to six months in prison for conspiring in the killing. On July 18, the Phnom Penh Municipal Court sentenced Heng Pov, former Phnom Penh police commissioner and under secretary of state of the Ministry of Interior (MOI), to an additional 22.5 years in prison for the 2005 illegal detention of a person, use of illegal weapons, and possession of counterfeit currency. Heng Pov was already serving an 18‑year sentence for the 2003 murder of Judge Sok Sethamony, multiple counts of premeditated killings, and involvement in illegal arrests and detentions. During his July trial, Heng Pov stated that Born Samnang and Sok Sam Oeun, the two suspects he ordered arrested in 2005 and who later were convicted for the killing of union activist Chea Vichea, were innocent of the crime. On April 12, the appeals court had upheld 20‑year sentences each for Born Samnang and Sok Sam Oeun. Their lawyers submitted grievances to the Supreme Court, and at year's end they awaited Supreme Court action. There were no developments in the 2006 cases of SRP activists Koent Chhuon and Thoeung Thear, killed in Preah Vihear and Kampong Cham provinces, respectively. Likewise, there were no developments in the cases of Pao Rum and Khat Thoeun, who died in police custody in Kandal Province in 2006, or the 2006 cases of attempted prison breaks in Kampong Thom and Battambang that left 10 inmates dead. In the case of Nong Sam, who reportedly died June 2006 in a Siem Reap hospital from head injuries received during a beating by police officers, a provincial court prosecutor closed the case, declaring Nong Sam's death a suicide. There were no developments in the 2005 killings of five SRP activists or in the 2005 case of an attempted escape from Trapoeung Phlong Prison in which 19 prisoners and the prison director were killed. The appeals court took no action in the 2005 deaths of five villagers and injuries to others by government security forces during a mass eviction from disputed land in the village of Kbal Spean in Banteay Meanchey Province. On February 8, in Prey Veng Province, district‑ and commune‑level deputy police chiefs Bun Samphea, Suos Bunthat, and Hay Chivon, charged in a 2000 killing, failed to appear for their provincial court trial, reportedly stating they were too busy. The court rescheduled the trial to June but postponed it again after the officers said they were too busy to come to the June trial. A new trial date was not set. Mines dating from the Indochina conflict and Khmer Rouge period continued to cause casualties. According to the Cambodia Mine/UXO Victim Information System, during the year mines and unexploded ordnance caused 63 deaths, 56 amputations, and 222 other injuries. Vigilante justice and mob killings persisted. ADHOC reported that mobs killed five persons during the year. Few suspects were arrested. In some instances authorities could not protect suspects from angry mobs. NGOs noted that a majority of mob killings were related to thefts, robberies, or suspected witchcraft. On June 9, Yos Chor villagers in Kampong Speu Province killed a person for stealing a neighbor's chickens. On June 21, a mob killed a traditional healer in the Boribo District of Kampong Chhnang Province because they suspected him of witchcraft. Police made no arrests in either case. On June 27, the Kratie Provincial Court sentenced six persons to sentences ranging from seven to 10 months in prison for the 2006 vigilante justice killing of Sam Roeun. The court convicted them on charges of causing injury, reduced from investigation findings of murder. There were no developments in the February 2006 case of a person beaten and killed for allegedly practicing witchcraft. On June 30, Khmer Kampuchea Krom monk Tim Sakhorn, head of a pagoda in the Kirivong District of Takeo Province for more than 10 years, disappeared. Previously, on orders of the country's top Buddhist leader, Great Supreme Patriarch Tep Vong, monks from Phnom Penh had defrocked Tim Sakhorn, after which unidentified persons believed to be attached to the MOI pushed him into a vehicle and drove away. The defrocking order stated Tim Sakhorn "broke the solidarity" between Cambodia and Vietnam by using pagodas to spread propaganda that affects the dignity of Buddhism. The monk was known locally for providing food and shelter to Khmer Kampuchea Krom coming from Vietnam. The MOI stated that Tim Sakhorn volunteered to go to Vietnam after he was defrocked, and ministry officials produced a document stating this intent. While signed by Tim Sakhorn, the handwritten document appeared not to be in his writing. On August 2, Tim Sakhorn reappeared in court custody in Vietnam, held on charges of destroying political solidarity. In September the Information Ministry stated that the Cambodian consulate in Ho Chi Minh City was investigating Tim Sakhorn's condition in detention. On November 8, a Vietnamese newspaper reported that a court in Vietnam convicted Tim Sakhorn of undermining solidarity between Cambodia and Vietnam and sentenced him to one year in prison. On August 10, Land Border Protection Unit 504 soldier Im Bun Ny disappeared in Pailin. According to witnesses, that night four soldiers from his unit invited him to a rubber plantation owned by their unit commander, Brigadier General Pol Sinuon. After Im Bun Ny arrived, the four soldiers beat him and accused him of stealing a gun. Unconfirmed witness reports said Im Bun Ny died from the beating and the soldiers buried his body. At year's end Im Bun Ny was still missing. According to a human rights NGO, local police completed an investigation and submitted findings to the court. The court took no action, and the four soldiers remained at large. c. Torture and Other Cruel, Inhuman, or Degrading Treatment or Punishment The constitution such practices; however, beatings and other forms of physical mistreatment of police detainees and prison inmates continued to be a serious problem. There were credible reports that military and civilian police officials used physical and psychological torture and severely beat criminal detainees, particularly during interrogation. Based on interviews with 1,293 detainees from 18 of the country's 26 prisons, the Cambodian League for the Prevention and Defense of Human Rights (LICADHO) reported that during the year authorities tortured 155 prisoners, of whom 125 were tortured in police custody and 30 in prisons. Kicking, punching, and pistol whipping were the most common methods of physical abuse, but techniques also included electric shocks, suffocation, caning, and whipping with wire. NGOs reported that it was not uncommon for police to torture detained suspects until they confessed to a crime. Courts used forced confessions as legal evidence during trial despite admissibility prohibitions under the law. NGOs noted that during the year there were 180 cases of physical assaults by local authorities, government agents, or private bodyguards, compared with 164 cases in 2006 and 154 cases in 2005. On May 27, military police officer Prak Vutha of Phnom Sruoch District, Kampong Speu Province, reportedly arrested Sok Soeun after a small scuffle at a restaurant, kept him in military detention overnight without a warrant, and beat him unconscious. According to ADHOC, Sok Soeun's family gave Prak Vutha two cases of beer in return for Sok Soeun's release. Sok Soeun later filed a complaint with local police that the police did not accept. There was no investigation into the case or legal action against Prak Vutha. No legal action was taken against two policemen from Border Protection Unit 701 implicated in a February 2006 beating of a 13‑year‑old boy. Likewise, there was no action against officials and no progress in the police investigation of an April 2006 case involving Police Commissioner Team Sangkriem in Preah Vihear Province and three other police agents who detained Kong Salath without a warrant and beat him. No disciplinary or legal action was taken against abusive officers in the April 2006 beating of a motorist by Battambang military police. Regarding the December 2006 case of Tous Sdoeung, whom two military police officers allegedly tortured to death while in detention, early in the year a provincial court prosecutor completed an investigation and forwarded it to an investigating judge. The court investigation continued. The two alleged perpetrators continued to work in their positions as military police officers. Prison and Detention Center Conditions Prison conditions did not meet international standards. Conditions remained harsh and at times were life threatening. Government efforts to improve them continued to be hampered by a lack of funds and weak enforcement. Human rights organizations cited a number of serious problems, including overcrowding, medical and sanitation problems, food and water shortages, malnutrition, and poor security. According to LICADHO, the 18 prisons they monitored had a designed capacity of approximately 6,440 inmates but held a total 9,582 inmates. There were reports at some prisons that cells of 40 by 20 feet held up to 110 prisoners. At CC1 prison, cells of 26 by 26 feet held an average of 50 prisoners. In some prisons authorities used shackles and held prisoners in small, dark cells as a form of harsher punishment. LICADHO reported that 56 prisoners in 18 of the country's prisons died during the year. Government ration allowances for purchasing prisoners' food routinely were misappropriated and remained inadequate, exacerbating malnutrition and disease. One NGO claimed that in some cases prison authorities sold the NGO's donations of supplemental food intended for prisoners. According to rights organizations, families had to bribe prison officials in order to visit prisoners or provide them food and other necessities. NGOs reported that prisoners whose families bribed prison authorities received preferential treatment including access to visitors, transfer to better cells, and the opportunity to leave cells during the day. There were reports that officials demanded bribes before allowing prisoners to attend trials or appeal hearings and before releasing inmates who had served full jail terms. In most prisons there was no separation of adult and juvenile prisoners, of male and female prisoners, or of persons convicted of serious crimes and persons detained for minor offenses. Pretrial detainees were routinely held together with convicted prisoners. LICADHO reported that there were 622 incarcerated minors ages 13 to 17, many of whom were held in prisons that did not have facilities to separate minors from adult prisoners. The government generally continued to allow international and domestic human rights groups, including the International Committee of the Red Cross, to visit prisons and provide human rights training to prison guards. However, NGOs reported that at times cooperation from local authorities was limited. Authorities curtailed access to pretrial detainees, in particular. The MOI continued to require that lawyers, human rights monitors, and other visitors obtain permission prior to visiting prisoners. The MOI withheld such permission in some politically sensitive cases. NGOs were not allowed to interview prisoners in private. d. Arbitrary Arrest or Detention The law prohibits arbitrary arrest and detention; however, at times the government did not respect these prohibitions. On June 7, the National Assembly passed a criminal procedures code, and in August the king signed the law into effect. The new code went allows for pretrial detention of up to six months for misdemeanors and 18 months for felonies. Prior to enactment of this code, the maximum length of pretrial detention for an adult person was six months under the UN Transitional Authority in Cambodia (UNTAC) code, although the government sometimes held pretrial detainees for longer periods. ADHOC reported that at least 100 persons were illegally arrested and detained during the year. ADHOC stated that 32 of those illegally detained were subsequently freed following detainee complaints, interventions by human rights NGOs, or payment of bribes. ADHOC believed that the actual number of arbitrary arrests and detentions was somewhat higher, because some victims in rural areas did not file complaints due to difficulty in traveling to the NGO's offices or out of fear for their family's security. According to ADHOC, no legal or disciplinary actions were taken against the persons responsible for the illegal actions. Role of the Police and Security Apparatus The General Commissariat of the National Police, which is under the supervision of the MOI, manages all civilian police units. The police forces are divided into those who have the authority to make arrests, those without such authority, and the judicial police. Military police are permitted to arrest civilians on military property or when authorized by local governments. Police officers acted with impunity, and in most cases the government took little or no action. There were reports that police, prosecutors, investigating judges, and presiding judges received bribes from owners of illegal businesses. The law requires police, prosecutors, and judges to investigate all complaints, including those of police abuses; however, in practice judges and prosecutors rarely conducted an independent investigation prior to a public trial. Presiding judges passed down verdicts based only on written reports from police and witness testimonies. In general police received little professional training. Police who failed to prevent or respond to societal violence were rarely disciplined. There were no developments in the April 2006 case of an antidrug department and military police officer who shot and injured a well‑known singer, Sovansocheata. No legal action was taken in the April 2006 case of two Brigade 70 military unit officers who shot and injured a person in Phnom Penh. There were no developments in the June 2006 case in which a military officer shot and injured a garment factory worker. In February an investigating judge in Siem Reap Province issued a warrant for the arrest of three police officers who allegedly raped a 12‑year‑old girl in November 2006; however, the suspects remained at large. There were no developments in the pending appeal of the April 2006 acquittal of three judges, two deputy prosecutors, and two court clerks originally convicted, then retried after appeal on finding of a mistrial, on charges of corruption and corruption‑related conspiracy. Arrest and Detention The law requires police to obtain a warrant from an investigating judge prior to making an arrest, but police may arrest without a warrant anyone caught in the act of committing a crime. The law allows police to take a person into custody and conduct an investigation for 48 hours, excluding weekends and government holidays, before charges must be filed. In felony cases of exceptional circumstances prescribed by law, police may detain a suspect for an additional 24 hours with the approval of a prosecutor. However, authorities routinely held persons for extended periods before charging them. Many prisoners, particularly those without legal representation, had no opportunity to seek release on bail. Under the new criminal procedures code, accused persons may be arrested and detained for up to 24 hours before meeting with a lawyer, but prisoners routinely were held for several days before gaining access to a lawyer or family members. According to government officials, such prolonged detention largely was a result of the limited capacity of the court system. LICADHO reported that as of midyear at least 101 pretrial detainees had been detained longer than the six‑month limit. Under the allowable pretrial detainee periods stipulated by the new code, at year's end there were at least 34 such prisoners. On May 19, two military police officers in Banteay Meanchey Province detained Kim Heang for three days after Kim Heang had a dispute with his neighbor, a regional military official. The two officers made the arrest without a warrant. After an NGO intervened, the officers' commander ordered Kim Heang released. No administrative or legal action was taken against the officers. On May 25, the Ratanakiri Provincial Court sentenced a 13‑year‑old Jarai ethnic minority youth to eight months and 10 days in prison for stealing brass gongs. The youth was 12 years old when arrested, under the minimum age for imprisonment, but spent more than eight months in pretrial detention. According to ADHOC, on May 25, a prosecutor filed a suit with the appeals court, but at year's end the youth remained in jail. On August 9, the Phnom Penh Municipal Court convicted six persons and acquitted two charged with planning bombings at the November 2006 Water Festival. Two of the convicted were sentenced in absentia to 12 years in prison. The remaining four received six‑year sentences. Lawyers and NGOs maintained the police did not serve arrest warrants or tell the suspects the charges against them. e. Denial of Fair Public Trial The constitution provides for an independent judiciary, but the government did not respect judicial independence. The courts were subject to influence and interference by the executive branch, and there was widespread corruption among judges, prosecutors, and court officials. The court system consists of lower courts, an appeals court, and the Supreme Court. The constitution also mandates a constitutional council, which is empowered to review the constitutionality of laws, and a supreme council of the magistracy, which appoints, oversees, and disciplines judges. The composition of both councils heavily favored the CPP. There is a separate military court system, which suffered from deficiencies similar to those of the civilian court system. While civilians may fall under military court jurisdiction in some cases, the legal distinction between the military and civil courts sometimes was ignored in practice. Civilians have been called for interrogation by military courts with no apparent jurisdiction in their cases. On June 12, the Extraordinary Chambers in the Courts of Cambodia (ECCC) adopted its internal rules to begin prosecuting egregious crimes of the 1975‑79 Khmer Rouge regime. On July 31, the ECCC coinvestigating judges charged Kaing Guek Eav (alias Duch), former Khmer Rouge director of the S‑21 torture prison, or Tuol Sleng, for crimes against humanity and placed him in an ECCC provisional detention center. The ECCC later arrested and detained four more Khmer Rouge leaders and charged them with crimes against humanity and war crimes: Nuon Chea (also known as "Brother Number 2"), Khieu Samphan, Ieng Sary, and Ieng Thirith, who was charged only with crimes against humanity. In August Duch's lawyers filed an appeal against his provisional detention. On December 3, the ECCC pretrial chamber decided unanimously to affirm the detention order and dismiss the appeal. Trials are public. Juries are not used; the presiding judge possesses the authority to pass a verdict. Defendants have the right to be present and consult with an attorney, confront and question witnesses against them, and present witnesses and evidence on their own behalf. If a defendant cannot afford an attorney, the court is required to provide the defendant with free legal representation; however, the judiciary lacked the resources to provide legal counsel, and most defendants sought assistance from NGOs or went without legal representation. Trials typically were perfunctory, and extensive cross‑examination usually did not take place. Defendants and their attorneys have the right to examine government‑held evidence relevant to their cases; however, at times it was difficult for them to obtain such access, especially if the case was political or involved a high‑ranking government official or well‑connected member of the elite. Defendants are entitled by law to the presumption of innocence and the right of appeal, but due to pervasive corruption, defendants often were expected to bribe judges to secure a verdict. A citizen's right to appeal sometimes was limited by difficulty in transferring prisoners from provincial prisons to the appeals court in Phnom Penh. Many appeals thus were heard in the absence of the defendant. A lack of resources, low salaries, and poor training contributed to a high level of corruption and inefficiency in the judicial branch, and the government did not ensure due process. From January through September, the Center for Social Development monitored 1,420 felony and misdemeanor hearings with 2,437 defendants and found trial procedure abuses in the Supreme Court, appeals court, and four lower courts. In a report of trials observed from January to March, the center stated that courts tried 34 percent of 740 defendants in absentia. At the appeals level, defendants were not present during trial in 69 percent of cases. Of defendants charged with felonies, 37 percent had legal representation, compared with 7 percent

Ampere's 1824 Laws
Theserelative motion laws greatly simply all of science:
These laws are essentially Ampere's simple 1824 long wire laws with a frequency modification. .These are universal laws that unify all the forces by seeing all forces as space-time creations similar to the way it's done in general relativity. . These laws, though, visualize different space-time intervals (different gauges) being created at various different spin/orbit frequencies.
Despite the fact that quantum theory does not see our type of spin causing angular momentum in the microcosm, these laws show it is there nevertheless but at a different space-time interval (different gauge - - different spin/orbit frequency level).
The "A" Laws
[The reason these "A" Laws work relates to the superposition principle that there is no repulsive force with in phase waves but a repulsive force (space) is always generated by out of phase waves].
You must also understand Dr. Milo Wolff's concept that particles (andtime) are manufactured by Spinning, Scalar, Standing Wave, Resonances with an immense, finite number of similar surrounding SSSWRs (Mach's principle).
Force (space) exists not DIRECTLY via scalar resonances but because of individual vector spin and orbital resonances between two similar Spinning, Scalar Standing Wave Resonances.
Remember, these"A" Laws (Ampere or Aufbau) have unified ALL the forces so these are now the NEW laws for everything, from the smallest spinning particle to the largest spinning super cluster of galaxies even where high relativistic speeds and mass are encountered. For simplicity, we must return to the Bohr concept of the electron. I have shown why in numerous other papers.
*The 1st. "A" Law shows us where all SSSWRs in relative motion produce the least space-time between themselves:
The space time interval is created theleast between any two SSSWRs, the closest sides of which "see" themselves spinning or moving on parallel paths in the same direction at the same frequency (like gears meshing) or a close harmonic thereof. You can also say these two objects will attract each other.
*The 2nd. "A" Law shows us where all SSSWRs in relative motion produce the most space-time between themselves:
Both space and time are created themost between any two SSSWRs, the closest sides of which "see" themselves spinning or moving on parallel paths in opposite directions at the same frequency (like gears clashing) or a close harmonic thereof. You can also say these two objects will repel each other.
I use the quoted word "see" to emphasize the particular spacetime realm in which these entities actually find themselves although this will NOT be the way it is seen from our particular spacetime reference frame realm.
Of great importance, in the two preceding laws, is that these laws arefrequency laws and they work separately for each separate spin/orbit frequency level which means these individual wave-particles must "see" themselves doing these things from their viewpoint in their local gauge environment. It does not matter how some other spin/orbit frequency level views these things because space and time and indeed the average space time interval is entirely different for each different spin/orbit frequency level (gauge).
These two laws look equal and opposite but they are not: The 1st"A" law "locks on" while its opposite 2nd sister law never does. This is because the total force is generally centralized and you can feel this 1st "A" law "lock on" when two magnets come together. These two laws result in limits of aggregation being established all throughout this universe: This is why there are limits to the size of atoms and limits to the size of stars as well.
*The Aufbau or Ampere Corollary
The aforementioned forces, or space-time intervals, between two SSSWRs will vary proportionally with the cosine of the angle of their paths. And they will have a torque that will tend to make the paths parallel and to become oriented so that SSSWRs on both paths will be traveling in the same direction.
All SSSWRs that "see" themselves traveling in the same direction on parallel paths at the same frequency will attract and/or space and time, at that frequency, between them is created the least.
All SSSWRs that "see" themselves traveling in opposite directions on parallel paths at the same frequency will repel and/or space and time between them, at that frequency, increases or is created the most.
And please don't forget this:
Why electrons, stars & galaxies repel each other
Remember, we have completely chucked out all those invisible forces you are familiar with and all we have now are these two"A" Laws.
Please remember, in thisnew "big picture" of everything, ALL FORCES ARE NOW UNIFIED so there are no such things as gravity, magnetic lines of force or plus and minus charges or for that matter even the strong force.
Pleasepay particular attention to the following.
Electrons can exhibit either an attraction or repulsion when they are "locked" spin up or spin down on orbitals such as like or unlike charges; like or unlike poles OR they may even display a gyroscopic type repulsive behavior when they are "free". Our"A" Laws show us why this is so and in the next 6 paragraphs you have the best explanation of why electrons and even stars & galaxies repel each other.
Lets look at these free electrons first: They spin and hence they have inertial qualities and this includes gyroscopic inertia which always provides this force 90 degrees to any external force acting on such a spinning item.
Completely forget about charge now and only look at our new"A" Laws and what they say.
The 1st "A" Law tells us that there is a possibility that two free electrons can attract each other providing that any portion of their closest sides are spinning in the same direction at the same frequency. This means either their sides can be spinning in the same directions or they can be lined up so that both of their poles can be spinning in the same directions: Any such two electrons will attract each other (magnetism also sigma and pi bonding).
Then we see that there is something else: This torque twisting force - on BOTH free items - depends on the cosine of the angle of their respective spin planes.
As this force begins to act, it in turn causes this 90-degree gyroscopic torque to twist both of those totally free electrons away from this initial attracting position, doesn't it?
So because of this gyro torque, two free electrons can never remain in a full attracting position and they will therefore be forced to stay more in arepelling position. Therefore free electrons will always end up repelling each other and this repelling is not explained by using this thing called charge: it is explained only by simply using global inertial qualities and our new global "A" Laws.
The above6 paragraphs explain not only why electrons repel each other but they also explain why any two perfectly free similar spinning SSSWRs of the same size must repel each other. So now you know why both electrons and galaxies stay well away from each other.
Thisis Einstein's cosmological constant.
Something somewhere has to be"locked" in place and synchronized in frequency (such as the electron's spin with another electron's spin) or a close subharmonic to get any kind of attracting force:
Yes, the proton attracts an electron but instead of charge please see it this way:
When two up quarks combine with one down quark to form a proton then the two up quarks are able to synchronize in with the electron's spin frequency and
This is why aggregations come together(gravity) and larger aggregations come together and accumulate because as these things grow in size there are more things "locked" in place strengthening the attractive force of the 1st "A" Law.
Once we knew about quarks then we should have realized how those two 'up quarks' in the proton are set up spin up-spin down (The 'up quark' does not signify orientation). Those two spin up--spin down 'up quarks' are spinning - in the same equatorial plane - at a higher frequency but all 'up quarks' spin at a harmonic of the electron's spin frequency allowing a spin up and spin down electron to be attracted to them in the same equatorial plane. We will soon know even more about theattractive quark strong force binding functions. Attraction is always a synchronized frequency attraction and it is not simply the old idea of plus and minus charges.
Allattractions in this theory must be synchronized frequency attractions.
Both light and inertial mass are caused by these synchronized frequency attractions.
As quantum theory shows us, the orbital of an electron on a distant star goes down a certain amount while the orbital of the electron receiving this quantum of energy---in your eye---goes up the exact same amount. But what quantum mechanics does not tell you is that these two energy-exchanging orbitals must be in the same exact plane. Not only that but each orbital must be a mirror image of the other with the electrons in each rotating and revolving in the exact opposite directions so that at the time the energy exchange takes place the closest sides of both electrons are going in the same direction. You can see from this that this energy change is merely a MOMENTARY DIRECT PULL from the electron, on the star, to the electron in your eye. These electrons will make many revolutions, rotations and wobbling oscillations during each change of those orbitals giving you the light that you see.
If two distant quarks are lined up so that their closest sides are in the same directions as the two aforementioned electrons then they too will momentarily bind with each other---even from a vast distance---and cause what we see as inertial mass. But since the quarks in the proton and neutron tri-quark entities do not oscillate and wobble quite like the electron then this pull of the two quarks is a steady momentary binding pull where BOTH quarks are pulled away from the other two quarks but NO PERMANENTEnergy CHANGE is made in either tri-quark entity (neutron or proton).
When you spin a flywheel and notice the gyroscopic inertia, you should also notice that the gyroscopic torque that is always 90 degrees to the axis of rotationcan also be seen as a linkage with the rim of the rapidly spinning flywheel to a path projected in the sky (macrocosm surroundings). The rim tries to stay in this path. This is showing you that you do have an absolute reference frame, which is Mach's principle. Billions of quarks in BOTH the flywheel and in the macrocosm are both being momentarily extended more than normal thus giving you this added gyroscopic inertia.
You might have to read the long TOE athttp://www.rbduncan.com/TOEbyFitzpatrick.htm to get the full picture of what happens when you crank up a gyroscope or a flywheel or ride a bicycle and produce gyroscopic inertia. It's similar to the reason you need cyclic pitch on a helicopter. When a helicopter moves forward then the blades on one side travel through the air faster than the blades on the other side and this tries to tip the helicopter over. (Igor Sikorsky had to invent cyclic pitch to prevent this).
The same thing happens to certain quarks whose rims line up with the rim of the gyroscope, flywheel or bicycle wheels. The speed that these items are turning---in respect to the macrocosm---now adds to portions of the quark rim speed which before was close to the speed of light and now gets even closer to the speed of light (becoming more massive hence at a higher frequency). So you are moving up an asymptotic curve close to that unsurpassable speed of c. And this---even with a miniscule number of quarks involved---gives us this gyroscopic inertia. It does this because the mass of these few quarks increase tremendously as portions of their rim speed approach the speed of light. As Einstein has shown us, mass increases with speed and especially increases when on that asymptotic portion of the curve.
Of available electrons, only the smallest fraction link with others a distance away to transfer light and heat. The same with the spinning quark that causes gyroscopic inertia. All spinning quarks link to cause inertial mass. All these binding linkages are momentary with the electron's oscillations causing a permanent transfer of energy and the various momentary quark bindings causing inertial mass. This could be seen---in gyroscopic inertia---as only a temporary transfer of inertial mass. But if you could increase our surroundings---as will be the case when our Milky Way galaxy finally collides with the Andromeda galaxy---then anyone here on earth will find both inertial mass, gyroscopic inertia and centrifugal force have all become stronger with the more crowded surroundings.
Now let's go to the stars and you will see the same"A" Laws apply there as well and, as you can see, these too will always have to remain in a repelling position with each other.
Recently Perlmutter discovered this acceleration and showed we must have Einstein'scosmological constant---a repulsive force---between all the stars and galaxies.
Scientists have been recently wracking their brains to figure out why we have Perlmutter's acceleration because nothing in our present science has even predicted such a thing.
But read those preceding blue sentences again! Now I hope you can finally see that our "A" Laws tell you exactly why we have Einstein's "cosmological constant" not only in the sky but in the microcosm as well. And they tell you why we have gravity too. Your present science doesn't even do this.
The reason these "A" Laws work is that this universe is built on an extraordinarily simple principle via an endless supply of vector wave resonances producing lower frequency spherical standing wave, scalar wave resonances that, in turn, produce space-time by spinning, orbiting and precessing.
Aminimum of space (at that particular frequency) is produced between the closest sides of spinning entities that are in the same scalar phase.
Scalar phaseis more like a movie frame than voltage phase, which pertains to a waveform.
These "A" Laws show us the production of the most important vector forces between the closest sides of such spinning spherical resonances and in the direction of the axis of each spin. There are also vector forces via orbits and spin and orbital and spin precessions.
This universe equalizes the energy vector force input to vector force output of these scalar wave resonances by balancing them on specific spin and orbital geodesics.
These vector forces, in turn, combine to produce lower frequency, hence lower energy, scalar resonances, which in turn, spin, precess and orbit producing still lower frequency space-time and its related vector forces and this goes on and on: Thus is our universe built from the microcosm to the macrocosm and may continue indefinitely because higher frequency waves would always be producing lower frequency, lower energy scalar wave resonances and they, in turn, would be producing even lower energy, lower frequency resonances.
This seems to be an infinite frequency universe with each spin/orbit frequency having inertial and gyroscopic qualities but yet with each spin/orbit frequency having its own distinct symmetry laws.

- science (n.)
- c.1300, "knowledge (of something) acquired by study," also "a particular branch of knowledge," from Old French science, from Latin scientia "knowledge," from sciens (genitive scientis), present participle of scire "to know," probably originally "to separate one thing from another, to distinguish," related to scindere "to cut, divide," from PIE root *skei- (cf. Greek skhizein "to split, rend, cleave," Gothic skaidan, Old English sceadan "to divide, separate;" see shed (v.)).
Science, since people must do it, is a socially embedded activity. It progresses by hunch, vision, and intuition. Much of its change through time does not record a closer approach to absolute truth, but the alteration of cultural contexts that influence it so strongly. Facts are not pure and unsullied bits of information; culture also influences what we see and how we see it. Theories, moreover, are not inexorable inductions from facts. The most creative theories are often imaginative visions imposed upon facts; the source of imagination is also strongly cultural. [Stephen Jay Gould, introduction to "The Mismeasure of Man," 1981]
Modern sense of "non-arts studies" is attested from 1670s. The distinction is commonly understood as between theoretical truth (Greek episteme) and methods for effecting practical results (tekhne), but science sometimes is used for practical applications and art for applications of skill. Main modern (restricted) sense of "body of regular or methodical observations or propositions ... concerning any subject or speculation" is attested from 1725; in 17c.-18c. this concept commonly was called philosophy. To blind (someone) with science "confuse by the use of big words or complex explanations" is attested from 1937, originally noted as a phrase from Australia and New Zealand.

“A remote Indian village is responding to global warming-induced water shortages by creating large masses of ice, or “artificial glaciers,” to get through the dry spring months. (See a map of the region.)
Located on the western edge of the Tibetan plateau, the village of Skara in the Ladakh region of India is not a common tourist destination.
“It’s beautiful, but really remote and difficult to get to,” said Amy Higgins, a graduate student at the Yale School of Forestry & Environmental Studies who worked on the artificial glacier project.
“A lot of people, when I met them in Delhi and I said I was going to Ladakh, they looked at me like I was going to the moon,” said Higgins, who is also a National Geographic grantee.
People in Skara and surrounding villages survive by growing crops such as barley for their own consumption and for sale in neighboring towns. In the past, water for the crops came from meltwater originating in glaciers high in the Himalaya.”

Mount Hope Cemetery: Restoring history
If you visit the Chinese Immigrant Memorial at Mount Hope Cemetery in Mattapan, Mass, you will notice that a lot of the headstones are in poor condition. This is due to aging, but it is also because of vandalism and lack of care for many years. Many of these headstones belong to the Chinese immigrants that created the Chinatown that we are able to enjoy today.
The first Chinese settlers of Boston Chinatown came from San Francisco, Ca, to North Adams, MA around the 1870s. These settlers consisted of about 75 workers who started working at the Sampson Shoe Factory in North Adams and later traveled to Boston. Chinese laundries and Chinese restaurants were soon established along Harrison Avenue. Overtime, Chinatown slowly began to evolve to include many other infamous streets such as Kneeland Street and Hudson Street.
Like many immigrants, the Chinese Settlers came to the United States for a better life for themselves and their family. Unfortunately, many of the early settlers were bachelors who did not have families in the United States nor were they able to have a family before they deceased. Many of these settlers that passed away were buried in Mount Hope.
Without family members, these headstones remained in Mount Hope Cemetery for decades without proper care. As any item with age, the heads stone deteriorated and some were even vandalized. Perhaps, it was fate for us to keep our history when the cemetery experienced financial burden which led the city to contact the Chinatown community. This attention was brought to two active members of the Chinatown community, Davis Woo and David S.Y. Wong, in 1989. And in 1992, when The Chinese Historical Society of New England (CHSNE) was established, they began the project to restore history. CHSNE and along with many efforts of volunteers had started a project in hopes to restore these burial grounds, build a memorial alter, and find a way to restore the damaged tombstones. With ambition and hard work, CHSNE and volunteers alike were able to raise an amazing amount of money.
On March 2007, the Chinese Immigrant Memorial was complete.
Although the Chinese Immigrant Memorial is complete, many efforts are still involved in this project. Every year, a group of students from UMASS Boston (UMB), led by Peter Kiang, Director of the Asian American Studies Program at UMB and co-president of CHSNE, try to maintain and clean the Chinese Immigrant Memorial. In addition, since the tombstones are privately owned by the descendants of the Chinese setters, it is considered private property. Currently, efforts are being made to contact these descendants. However, if efforts has been made but failed, these tombstones could be replaced.
For more information or if you would like to volunteer, please contact CHSNE: (617)338-4339 or email@example.com.

Oct. 3, 2011 -- Children who are overweight compared to their peers are nearly three times more likely to have high blood pressure, a new study shows.
The study, published in the journal Hypertension, followed 1,111 school-aged children in Indiana for an average of four years.
Twice each year, researchers visited schools to take blood pressure measurements and record the kids’ heights and weights.
About 40% of the children in the study were above the 85th percentile on growth charts for their height and weight. When children are above the 85th percentile, doctors consider them to be overweight.
Among the overweight kids, 14% had blood pressure that was higher than normal, while only 5% of normal-weight kids had elevated blood pressure.
The study also found that extra pounds are especially dangerous for kids who are already big.
"For an overweight and obese child, if you increase your BMI [body mass index] percentile a little bit, that would increase your blood pressure strongly,"says researcher Wanzhu Tu, PhD. Tu is a research scientist at Regenstrief Institute and professor of biostatistics at Indiana University School of Medicine, both in Indianapolis.
"In the same way," Tu says, for just a little bit of weight loss "you could benefit greatly in terms of blood pressure."
The risks of overweight were the same, regardless of the child’s sex or race. About 42% of the kids in the study were black.
Pediatricians say the study is wake-up call.
"We’ve tended to look at the overweight category as a lower-risk category," says Stephen R. Daniels, MD, PhD, chairman of the department of pediatrics at the University of Colorado School of Medicine in Denver. He was not involved in the research.
"This suggests to me that we really need to worry about kids who are in that overweight category," says Daniels, who is also pediatrician-in-chief at Colorado Children’s Hospital.
Other experts say the findings are concerning because having high blood pressure has been shown to set kids up for health complications.
Not only are children with high blood pressure much more likely to turn into adults who have high blood pressure, but newer studies have shown that kids can get the same kinds of organ damage -- to the heart, blood vessels, and kidneys -- that doctors once thought was only a problem for adults with the condition.
One study even found that kids with high blood pressure have subtle changes in the brain area that controls attention, problem solving, and working memory.
"For physicians, we have to take much more seriously this concept of the childhood origins of adult diseases and look beyond the weight and beyond the blood pressure level because we’re finding more evidence, subtle evidence, of injury," says Bonita Falkner, MD, professor of medicine and pediatrics at Thomas Jefferson University in Philadelphia.
"So it’s not going to be a risk that’s going to be in the future. It’s a risk that’s now," says Falkner, who wrote an editorial on the study, but was not involved in the research.
"It jacks up the concern about preventing childhood obesity and also not waiting until they are obese," she tells WebMD. "Even overweight can be problematic for children."

Blocking production of a pyruvate kinase splice-variant shows therapeutic promise
Cold Spring Harbor, N.Y.
– Cancer cells grow fast. That’s an essential characteristic of what makes them cancer cells. They’ve crashed through all the cell-cycle checkpoints and are continuously growing and dividing, far outstripping our normal cells. To do this they need to speed up their metabolism.
CSHL Professor Adrian Krainer and his team have found a way to target the cancer cell metabolic process and in the process specifically kill cancer cells.
Nearly 90 years ago the German chemist and Nobel laureate Otto Warburg proposed that cancer’s prime cause was a change in cell metabolism – i.e., in cells’ production and consumption of energy. In particular cancer cells have a stubborn propensity to eschew using glucose as a source to generate energy. This is known as the Warburg Effect.
While metabolic changes are an important feature in the transformation of normal cells into cancer cells they are not now thought to be cancer’s primary cause. Despite this, metabolic changes remain an attractive target for cancer therapy, as Krainer and colleagues show in a paper published online today in Open Biology
, the open-access journal of Great Britain’s Royal Society.This image compares glioblastoma cells untreated or treated with antisense oligonucleotides (ASO) that modulate splicing for PK-M. The cells are visible under light microscopy in the left column, and the DNA in their nuclei shows up when using the blue dye DAPI in the second column. PK-M2 is visualized using a red stain in the third column, with the merge of the images in each row in the forth column. The 2nd and 3rd rows show cells that have been treated with ASOs. The red dye is nearly all gone indicating that there is less PK-M2 and that the ASOs have worked. Image courtesy of Zhenxun Wang and Adrian Krainer. (click to enlarge)
One difference between metabolism in cancer and normal cells is the switch in cancer to the production of a different version, or isoform, of a protein produced from the pyruvate kinase-M (PK-M) gene. The protein version produced in normal cells is known as PK-M1, while the one produced by cancer cells is known as PK-M2.
PK-M2 is highly expressed in a broad range of cancer cells. It enables the cancer cell to consume far more glucose than normal, while using little of it for energy. Instead, the rest is used to make more material with which to build more cancer cells.
PK-M1 and PK-M2 are produced in a mutually exclusive manner -- one-at-a-time, from the same gene, by a mechanism known as alternative splicing. When a gene’s DNA is being copied into the messenger molecule known as mRNA, the intermediate template for making proteins, a cellular machine called the spliceosome cuts and pastes different pieces out of and into that mRNA molecule.
The non-essential parts that are edited out are known as introns, while the final protein-coding mRNA consists of a string of parts pasted together known as exons. The bit that fits into the PK-M1 gene-coding sequence is known as exon 9, while it is replaced in PK-M2 by exon 10. In this way alternative splicing provides the cell with the ability to make multiple proteins from a single gene.
Krainer, an authority on alternative splicing, previously published research
on the protein regulators that facilitate the splicing mechanism for PK-M. His team showed that expression of PK-M2 is favored in cancer cells by these proteins, which act to repress splicing for the PK-M1 isoform. In the study published today the team explains that it decided to target the splicing of PK-M using a technology called antisense, rather than target the proteins that regulate the splicing mechanism.
Using a panel of antisense oligonucleotides (ASOs), small bits of modified DNA designed to bind to mRNA targets, they screened for new splicing regulatory elements in the PK-M gene. The idea was that one or more ASOs would bind to a region of the RNA essential for splicing in exon 10 and reveal that site by preventing splicing of exon 10 from occurring.
Indeed, this is what happened. “We found we can force cancer cells to make the normal isoform, PK-M1,” sums up Krainer. In fact, a group of potent ASOs were found that bound to a previously unknown enhancer element in exon 10, i.e., an element that predisposes for expression of the PK-M2 isoform, thus preventing its recognition by splicing-regulatory proteins. This initiated a switch that favored the PK-M1 isoform.
When they then deliberately targeted the PK-M2 isoform for repression in cells derived from a glioblastoma, a deadly brain cancer, all the cells died. They succumbed through what is known as programmed cell death or apoptosis -- a process whereby the cell shuts down its own machinery and chops up its own DNA in committing a form of cellular suicide.
As to why the cells die when PK-M2 is repressed: the team found it was not due to the concomitant increase in PK-M1 (the cells survived even when extra PK-M1 was introduced). Rather, it was the loss of the PK-M2 isoform that was associated with the death of the cancer cells. How this works is still unclear but a subject of investigation in the Krainer laboratory.
The next step will be to take their ASO reagents into mouse models of cancer to see if they behave the same way there. While there are some technical and methodological obstacles to overcome, Krainer is optimistic.
“PK-M2 is preferentially expressed in cancer cells, a general feature of all types of cancer -- it’s a key switch in their metabolism,” he says. Thus targeting the alternative splicing mechanism of PK-M2 using ASOs has the potential to be a cancer therapeutic with many applications.

Cyber Bullying Leaflet Launch
Sue Ball Consultant for BRAG and Parents from Nechells Parents Forum launched a leaflet of advice for parents and carers about how to prevent and tackle cyber-bullying. Cyber-bullies use the internet, mobile phones or any other form of digital technology to threaten, tease or abuse someone.
This useful resource, produced by Birmingham City Council’s Young People and Families Directorate, in association with Nechells Parents Forum and the POD, helps parents understand how to be cyber-safe, how to spot the signs if their child is a victim of or an instigator of cyber-bullying and what steps to take to stop it. The leaflet provides useful, practical advice with local and national contacts for further support and guidance.
The launch took place at Nechells Zone Olympics at the Alexander Stadium on June 15th Noran Flynn, Director of the POD, and organiser of the Olympics Event said “Nechells parents are keen to support their children at our Olympics, and promote the values of respect, excellence and friendship. They are also very concerned about the rise in cyber-bullying and have worked hard, with Birmingham’s Bullying Reduction Action Group (BRAG) to produce this leaflet to help parents across Birmingham deal with cyber-bullying and keep their children safe”
How to tackle cyber-bullying:
New technologies are amazing. Mobile phones, smart phones, the internet and social networking slites like facebook allow us to keep in touch with our friends and family more easily and to have access to a wide range of information on the world-wide web. They can help children with their learning, prepare them for life in a technological world and improve their communication skills.
But as well as the positives, we all know that there are some negatives and that cyber-bullying is on the increase. Because many children and parents are worried about cyber-bullying Nechells Parents Forum have worked with Birmingham City Council’s Bullying Reduction Action Group (BRAG) to produce an advice leaflet for parents called How to Tackle Cyber-bullying.
This leaflet helps parents understand what cyber-bullying is, how to spot the signs if their child is a victim of or an instigator of cyber-bullying and what steps to take to stop it. It also gives useful, practical advice with local and national contacts for further support and guidance.
Sue Ball said “The Olympic values of respect, excellence and friendship are important to us all. Thank you to the POD and all the members of Nechells Parents Forum, who helped to create this leaflet. It gives great advice to parents and carers across Birmingham about how they can best help their children to lead happy and bully-free lives, build respectful friendships and stay safe from cyber-bullying.”

Some pupils from year 5 in our Nechells EAZ schools: Cromwell, Nechells, St Clement's, St Joseph's and St Vincent's all went to Aston University today for a day of fun, experiments, experiences and inspiration for their future careers. The young people learnt all about team work, had a tour of the campus and then became mini scientists extracting DNA from kiwi fruits. The Nechells Schools and their pupils would all like to say a big thank you to Bal and her team of student volunteers at Aston University for the opportunity they give every year to some our most Gifted and Talents pupils, they really enjoy this fantastic experience, we hope that our pupils will all continue to study hard and in time become the graduates of the future.

Information for Students
Welcome to the Flint Regional Science Fair! We look forward to seeing you at the Fair in March.
Taking part in a science fair is fun, educational, and rewarding. This part of our web site provides information and links that can help you get started, conduct your research and enter the Flint Regional Science Fair.
The FASF is held every Spring. This means you should begin planning in the Fall and Winter prior to the Fair to ensure you pick a good research topic, and have plenty of time to do a good job and present a quality project.
Parents, teachers, and mentors are important helpers to identify projects, collect the resources required for your project, and track your progress. Ask your parents and your teachers for assistance. They are your best bet for one-on-one direction and support in your Science Fair experience.
Elementary Division and Junior Division projects follow simpler rules than Senior Division projects.

Dermatology is the a branch of medical science dealing with the skin, its structure, functions, and diseases.
Dermatologists specialize in diagnosing and treating conditions related to the skin, hair, and nails, including concerns related to cosmetic issues, such as sun damage and aging, as well as skin cancer, and other medical skin conditions.
Dermatologists who have additional interest and skill in performing surgical procedures are referred to as dermatologic surgeons or dermasurgeons.
Specialty terms like "dermatologist" and "dermatologic surgeon" are often unregulated and may be used in some states by any doctor, regardless of their training and credentials.
So, for instance, a doctor who has an active medical license and is board certified in Internal Medicine but who has not undergone any specialty training in dermatology may refer to him or herself as a dermatologist or dermasurgeon, despite the fact that their training and credentials may not reflect specialization in this area of medical practice.
The skin is the largest organ of the human body, and as a result, dermatologists typically offer a wide variety of treatments for it.
Whether you wish to correct wrinkles, crepey skin, or razor bumps, a board certified dermatologist or dermasurgeon may help you by offering a single treatment or any combination of the following:
Cosmetic dermatology - Non-surgical procedures
- Laser treatments
- Chemical peel
- Injectable fillers
- Botox and Dysport
- Lip augmentation
- Non-surgical nose job
- Non-surgical facelift
- Acne treatment
- Acne scar removal
- Vein treatment
- Scar removal
- Skin tightening
Cosmetic dermatology - Surgical procedures
Most dermatologists and dermasurgeons also offer treatments for a variety of medical skin conditions, in addition to cosmetic treatments. Although most skin problems can create aesthetic concerns, the following conditions are usually considered medical issues, and treatment may be covered by insurance.
Medical dermatology - Conditions treated
- Skin cancer
