- Publisher's Summary
- Conventional wisdom holds that freedmen's education was largely the work of privileged, single white northern women motivated by evangelical beliefs and abolitionism. Backed by pathbreaking research, Ronald E. Butchart's "Schooling the Freed People" shatters this notion. The most comprehensive quantitative study of the origins of black education in freedom ever undertaken, this definitive book on freedmen's teachers in the South is an outstanding contribution to social history and our understanding of African American education.

New text book on Nuclear Chemistry
The Publisher Walter de Gruyter, Berlin / New York, will publish a new text book on
Nuclear Chemistry for University students, to be edited by Frank Rösch.
This text book is conceived to meet the demand of state-of-the-art literature to teach the
fundamentals as well as the modern applications of nuclear chemistry. The work will consist of two
volumes: the first one covering the basics of nuclear chemistry such as the relevant parameters of
instable atomic nuclei, the various modi of radioactive transmutations, the corresponding types of
radiation including their detection and dosimetry, and finally the mechanisms of nuclear reactions. The
second volume addresses relevant fields of nuclear chemistry, such as the chemistry of radioactive
elements, application of radioactive nuclei in life sciences, nuclear energy, waste managements and
environmental aspects, radiochemical separations, radioanalytical and spectroscopic methods, etc.
Here, leading experts will contribute the recent knowledge on individual aspects.
Frank Rösch is author of more than 200 peer-reviewed papers and book chapters on fundamental and
applied radiochemistry and editor of the 5-volume Handbook of Nuclear Chemistry. In 1996 he was
appointed professor of Nuclear Chemistry and Radiopharmaceutical Chemistry at the Institute of
Nuclear Chemistry of the Johannes Gutenberg-University of Mainz, Gemany.


1. The problem statement, all variables and given/known data A man stands on the roof of a building of height 14.1 m and throws a rock with a velocity of magnitude 31.6 m/s at an angle of 25.0 above the horizontal. You can ignore air resistance. Calculate the maximum height above the roof reached by the rock. Calculate the magnitude of the velocity of the rock just before it strikes the ground. Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground. 2. Relevant equations V^2 = V initial ^2 + 2a(x-xo) 3. The attempt at a solution The first part is the part, that I am getting stuck on, the other two parts of the question following it hopefully I will be able to do, as I encountered that type of problem before. Anyways, my attempt: Max height = unknown Angle : 25 degrees Vy = 0 m/s (at the highest point, Velocity is 0. Vy initial is 13.35 m/s. ( I got this using 31.6 sin 25) Height at beginning is 0. (Ignoring the fact that's the building is 14.1m) 0 = 13.35^2 + 2 (-9/8)(y-0) -178.22 = -19.6y y = 9.09 m does this seem right?


COVID-19 has posed unprecedented challenges to governments and civil society worldwide. Before effective treatments and vaccines become available, nonpharmaceutical interventions (NPIs), including digital contact tracing technologies, are critical for delaying or controlling the spread of COVID-19. This paper investigates the practices, discussions, and legal and ethical issues of the contact tracing measures imposed in Taiwan during the COVID-19 pandemic. Read more
By analyzing official documents from the Ministry of Health and Welfare website, media reports, legal regulations, international organizations’ ethical guidelines, and research on contact tracing measures, this paper categorically presents the applications, effectiveness, and legal and ethical concerns of these measures in Taiwan. Results: Although the rates of confirmed cases and deaths from COVID-19 are low in Taiwan, the Electronic Fence of Surveillance, a digital contact tracing measure implemented by the National Health Command Center, was found to lack legal certainty. Some proactive deployments by public and private organizations that have used location-based services, the National Health Insurance system, and the center’s data on of the digital footprints of confirmed cases do not meet ethical and scientific validity standards. Oversight mechanisms have not been established, and public reflection has not been addressed. Conclusions: This paper argues that the choice of upholding individual privacy rights versus performing digital contact tracing is not binary. To make digital technologies part of measures against COVID-19, and future public health crises, it is crucial to include diverse experts not only of information technology and biomedicine, but also of epidemiology, public health, law, ethics, and social sciences, as well as civil organizations in the design, application, oversight, and evaluation of new public health technologies.


Scientists have found fossils in China of the earliest known birds with well-preserved plumage and features associated with both flight and wading.
Archaeornithura meemannae lived about 130.7 million years ago, five to six million years before the previous oldest-known bird specimens.
The two well-preserved fossils, announced in the journal Nature Communications, are the oldest known records of Ornithuromorpha, the same evolutionary branch which gave rise to all bird species now living.
Fossilised bird specimens from the Mesozoic era are rare with little being known about the early evolutionary history of the ancestors of modern birds.
Min Wang of the Chinese Academy of Science and colleagues describe this new species, found in the Sichakou basin in Hebei, as having a near-completely preserved plumage with anatomical features characteristic of an aerodynamic lifestyle and manoeuvrability during flight.
The absence of feathers on the upper leg is also indicative of a wading lifestyle, consistent with other fossil bird species found in similar deposits.


The Illinois State Museum has an active research program in Entomology.
The strengths of the program include research on Lepidoptera
(butterflies and moths) and Odonata (dragonflies and damselflies) of
Illinois and the Midwestern United States.
One of the most exciting areas of current research is on the
distribution, ecology, behavior, and genetic variation of
Hine's emerald dragonfly (Somatochlora hineana).
This species is on the Federal and Illinois State endangered
species list. Two ISM scientists are on the Recovery Team
for this species.


Cognitive skill development in children involves the progressive building of learning skills, such as attending, memory and thinking. These crucial skills enable children to process the sensory information they experience and eventually learn to evaluate, analyze, remember, make comparisons and understand cause and effect.
Ivanov, V.K. and Geake, J.G. (2003) ‘The Mozart Effect and Primary School Children’, Psychology of Music, 31(4): 405–13.
This study found some evidence for the existence of a Mozart Effect with upper-primary school-aged children in a school setting. Scores on a Paper Folding Task (PFT) for a class which listened to Mozart during testing were significantly higher than the PFT scores of a control class. Moreover, a similar result was obtained for another class which listened to Bach during testing. The musical educational experience of the children, ascertained by a Musical Background Questionnaire, did not significantly contribute to the variance in PFT scores. We believe that this study is the first to find a Mozart Effect for school children in a natural setting, in contrast to the original study of Rauscher, Shaw and Ky (1993) who examined the effects of listening to Mozart on the spatial task performance of university students in a laboratory.


In normal circumstance, the voltage wave is sine wave. When there is lighting strike ,or inappropriate operation, even the system setting may cause some part of the system has the voltage over the durability.The rate voltage and the environment have to be considered before design the insulation structure. The product has to test the withstanding voltage to make sure the insulation structure is strong enough. A HI POT Tester checks for “goodisolation”and makes surety of no current will flow from one point to another point.
When short happened on coil, it may change the parameter of inductance , capacitance, and resistance. The insulation ability reduce. Usually, the problem will be discover under high voltage. Without the high voltage, the defection point is hard to be penetrated. About The Impulse Tester. “Pulse voltage and waveform comparison” is the way we detect layer short. The pulse voltage is non-destructive/instant voltage that apply on both side of winding and detect the DUT without damage it. By compare the wave with the golden sample, we can judge the DUT.


A strategic evaluation framework to guide the planning and evaluation of food systems programming
The CFS team’s strategic evaluation framework has been developed through a series of steps. First the CFS coordinating committee was introduced to the concept of Whole Measures for Community Food Systems in two trainings with the consultant who co-developed at the Center for Whole Communities. The CFS coordinating committee then introduced Whole Measures to the CFS team at the northern regional meeting in January 2013. After, the CFS coordinating committee used a participatory process at various meetings and through email communication to draft the following for each value field: 1) Definition of each value-field, 2) Examples of county educators and state specialists’ programming, and 3) Examples of outcomes & indicators. The CFS coordinating committee used this gathered information to draft definitions, activities, outcomes, and indicators for each value-field and developed this Whole Measures planning and evaluation framework for food systems programming. Please note the CFS Team adapted the framework by adding an additional value field, Innovative Collaborations.
Whole Measures for Community Food Systems. 2009 Community Food Security Coalition
Description: This evaluation and planning tool provides communities with methods to measure and connect indicators that define a healthy, connected food system. Indicators consider justice issues, health, farm health, human health, local economics, and community building issues.


The sense of balance typically worsens with age. It can be further compromised by certain medical conditions and medications, uncorrected vision problems, or a lack of flexibility. Poor balance often leads to falls, which can cause head injuries and other disabling injuries. Hip fractures, in particular, can lead to serious health complications and threaten independence. A combination of activities such as walking, strength training, and specific workouts can improve balance and prevent falls, especially in older adults.
Walking helps build lower-body strength, an important element of good balance. Walking is safe exercise for most people and, in addition to improving balance, counts toward your aerobic activity goals. If health problems make walking especially difficult for you, a physiatrist or physical therapist can suggest other options.
A good walking plan should be designed to safely boost physical activity whether you're sedentary or fairly active. The minutes count, not the miles. Here's how to tailor a walking plan to your needs:
If you aren't in the habit of exercising, start at the beginning. If you normally use a cane or walker, be sure to do so. As you feel stronger and more comfortable, gradually add more minutes to your walks.
If you already exercise, start with a walking plan that best matches your current routine and build from there. If the plan seems too easy, add time, distance, or hills. Aim for at least 150 minutes of walking per week, but don't hesitate to add more.

Numbering Your Fretboard
In this guitar lesson we are going to learn about the numbers of the frets on the guitar. This may seem like a simple topic, but if you are a beginner it is pretty important. If you can quickly understand where to put your fingers during a lesson, you won’t get frustrated and you will learn faster. We have provided you with a diagram of the fretboard with each of the frets numbered.
If your guitar has a different number of frets from the one you see in this video, don’t worry. Most electric guitars have 21, 22, or 24 frets. Fenders and Gibson style guitars usually have 21 or 22 frets. Ibanez and Jackson style guitars usually have 22 or 24 frets. If you have an acoustic guitar it will probably have around 20 frets.
Let’s look at a few examples to learn how to count the frets on the guitar. Let’s say that someone told you to put your 1st finger on the 5th fret of the 1st string. You would start counting on your open high E string as 0. From there, count 5 frets up. Now you would put your index finger on that 5th fret. Here is a diagram that shows the 1st finger on the 5th fret of the 1st string.
Now put your 2nd finger on the 12th fret of your 2nd string. Here is a diagram to show you where you should put your 2nd finger.
Learning how to count the frets is pretty simple so you probably won’t have to spend much time on getting the hang of it. You should realize that once you get to the 12th fret of your guitar, the notes just start repeating. For example, the 12th fret of your open high E string is another E. This E is just one octave higher. Most guitars will have fret markers to help you kind of keep your place when you are playing. These markers come in all different shapes and sizes. The most common shapes are dots, blocks, trapezoids, and shark fins.


SOURCE: Northwestern University, news release, Nov. 19, 2015
WEDNESDAY, Dec. 2, 2015 (HealthDay News) -- MRIs can spot the warning signs of knee osteoarthritis in people who have normal X-rays, researchers report.
They looked at 849 people, average age of 60, who showed no evidence of arthritis in either knee in X-rays. They were deemed at high risk due to factors such as being overweight or having a history of knee injuries.
The Northwestern University team also assessed cartilage damage, bone marrow lesions and meniscus tears on MRI images taken three years apart. If the MRIs showed worsening damage during that time, the patients were at increased risk of developing knee arthritis or symptoms such as pain, stiffness and/or swelling.
Depending on the type of lesion revealed by MRI, the risk of developing knee arthritis within three years was three to 20 times greater, the researchers said.
"These worsening lesions are an early warning sign and an opportunity to intervene before a person develops the debilitating disease," lead investigator Dr. Leena Sharma, a rheumatologist and professor of medicine, said in a university news release.
"If we employ aggressive prevention strategies in persons with these lesions before they develop knee osteoarthritis, we may be able to delay disease development or alter its course," she added.
Those preventive measures include weight control and avoiding potentially harmful physical activity.
The study was published recently in the Annals of the Rheumatic Diseases.
The U.S. National Institute of Arthritis and Musculoskeletal and Skin Diseases has more about osteoarthritis.


When we do exercises, we usually have two sessions here at the Emergency Operations Center (EOC). The first session is a "workshop" designed to run through checklists and procedures, make sure we catch any updates/changes and talk through the scenario. The second session is, generally, the real-time run through complete with injects designed to complicate the response or to test specific aspects of our procedures we want to stress, break, etc., so that we can fix them.
Today, we are conducting a workshop for a flood. The intent is to flood at a level large enough to stress local response capabilities and explore how the State might coordinate resources and offer support to affected populations.
In Colorado, we are familiar with flooding. It is a necessary component of what happens when snow melts. Thankfully, we rarely see the massive, overwhelming flood conditions that some areas the country seem to be routinely plagued. For more info on floods, flash floods and things you can do to be safe, check out DEM's flood page. In preparation for a flood or any disaster, remember to check out READYColorado for guidance and thoughts on how to prepare your family's emergency kit and communication plan.

Baragnosis is an inability to accurately judge weight with the cutaneous and muscle senses. It is usually a result of damage to the primary somatosensory cortex. This damage is commonly caused by a lesion or a subdural hemorrhage of the middle cerebral artery.
This should not be confused with the term barognosis which relates to the sense of weight or the ability to judge lifted weights.


Signs & Signifiers
Graffiti is a recurrent detail in Ferdinand’s crime scenes, with walls and fences covered in the signs and symbols of a violent underworld. “A name crossed out with an X shows someone killed by a rival gang, a name inside a tombstone is a tribute to a gang member or a friend,” he once told an interviewer. “A lot of times I use people I’ve known who’ve died on the street.” While often stark, Ferdinand’s drawings are marked by irony, metaphor, and a sometimes startling humor. Street signs are a favorite detail—in many pieces STOP, ONE WAY and DEAD END stand behind young men wearing gang colors and holding weapons. “I use telephone poles too—the crosses are like a symbol for crucifixion.” For over a decade, a Baptist church in New Orleans paid for a billboard at the intersection of Claiborne Avenue and Martin Luther King Jr. Boulevard, stating “Thou Shall Not Kill” as a grassroots response to the city’s murder rate. Ferdinand used this and much other signage in his art, adding background commentary to his scene at hand. Cemeteries are a cultural touchstone in New Orleans and, along with their tombstone crosses, frequently appear in his work.

Haberlea rhodopensis plants, growing under low irradiance in their natural habitat, were desiccated to air-dry state at a similar light intensity (about 30 μmol m(-2) s(-1)) under optimal (23/20°C, day/night) or high (38/30°C) temperature. Dehydration of plants at high temperature increased the rate of water loss threefold and had a more detrimental effect than either drought or high temperature alone. Water deficit decreased the photochemical activity of PSII and PSI and the rate of photosynthetic oxygen evolution, and these effects were stronger when desiccation was carried out at 38°C. Some reduction in the amount of the main PSI and PSII proteins was observed especially in severely desiccated Haberlea leaves. The results clearly showed that desiccation of the homoiochlorophyllous poikilohydric plant Haberlea rhodopensis at high temperature had more damaging effects than desiccation at optimal temperature and in addition recovery was slower. Increased thermal energy dissipation together with higher proline and carotenoid content in the course of desiccation at 38°C compared to desiccation at 23°C probably helped in overcoming the stress.

What are the risk factors for prostate cancer?
A risk factor is anything that increases a person's chance of getting a disease. Different cancers have different risk factors. Some risk factors, such as smoking, can be changed. Others, like a person's age or family history, can't be changed.
But risk factors don't tell us everything. Many people with one or more risk factors never get cancer, while others with this disease may have had few or no known risk factors. While we do not yet know exactly what causes prostate cancer, we do know that certain risk factors are linked to the disease.
- Age: Risk of prostate cancer goes up as men get older
- Race: In the US, African-American men are more likely to get prostate cancer and die of it than in men of other races.
- Nationality: Prostate cancer is most common in North America, northwestern Europe, Australia, and the Caribbean and less common in Asia, Africa, Central and South America.
- Family history: Men with close family members (father or brother) who have had prostate cancer are more likely to get it themselves, especially if their relatives were young when they got the disease.
- Genes: Scientists have found some inherited genes that seem to raise prostate cancer risk, but they account for only a small fraction of cases.
- Diet: Men who eat a lot of red meat or high-fat dairy products seem to have a greater chance of getting prostate cancer.
- Obesity: Some studies have found that obese (very overweight) men may be at greater risk for having more advanced prostate cancer and of dying from prostate cancer, but not all studies have found this.

The Endeavour Project at the University of Cambridge (the project formerly known as VBRAD) is investigating the use of computer vision and related technologies in the automotive world, and in particular how we can develop a better understanding of the driver's activities, emotions, and environment.
The aim is to allow cars and their related systems to make more intelligent decisions about how to keep the driver informed, comfortable, safe, and heading in the direction they want to be going!
Here's an example...
Smarter vehicle-initiated communication
My current focus is on the process by which a car communicates with the driver. There are many things a car may want to tell you during your journey, and they all have different degrees of importance or urgency. Some examples might include:
- Your brakes have failed.
- You need to turn left in 100 metres.
- Your phone is ringing. It's your mother.
- You need to take the next exit, in 5 miles.
- You need fuel in the next 50 miles.
- A service is due in the next 1000 miles.
- That was 'Shake it off' by Taylor Swift.
- You're crossing the River Don, an important navigational canal serving the city of Sheffield.
At present, your car will typically just inform you of such things as soon as the information becomes available. But if you're negotiating a difficult junction with fast oncoming traffic, the last thing you need is to hear a 'ping' and see a warning light flash to tell you that you need a service in the next thousand miles.
We think we can do better.
(This project has some factors in common with my Augmented Vehicles work, many years ago at AT&T.)

Direct Loans Could Save Billions in First 5 Years With Proper Implementation
HRD-93-27: Published: Nov 25, 1992. Publicly Released: Nov 25, 1992.
- Full Report:
Pursuant to a congressional request, GAO reviewed potential savings to the government by using direct rather than guaranteed loans to provide assistance to postsecondary school students, focusing on: (1) how direct loans achieve cost savings; and (2) the impact of direct lending on financial institutions.
GAO found that: (1) direct student loans could save the federal government about $4.8 billion for loans made in fiscal years 1994 through 1998; (2) the government could use interest earnings from direct student loans to curtail program costs; (3) lower program costs would lessen start-up and administrative costs, but not offset federal cost savings; (4) savings derived from Stafford loans could total $3.2 billion; and (5) there were concerns about whether the Department of Education could efficiently administer the program nationally.

Royal Dutch Airlines (KLM) is investing in a new technology for supersonic flight, the first such effort since British Airways shut down the Concorde in 2003. An outside investor has chipped in $164 million to kick-start the project, Space Tourism Curacao, which could theoretically connect any two cities on Earth within two hours' flight.
A test model of the space jet is set to debut next spring, and its owners aim to start commercial flights from the Caribbean island of Curacao in 2014. That said, regularly scheduled flights from major cities may take another two decades to appear.
The craft is essentially a spaceship, with the breakthrough technology of a reusable engine.
Passengers will be required to pass physical tests to fly on the craft just as a flight attendant must for today's ordinary planes. Passengers must be prepared to travel at speeds of up to 13,750 mph.
The new craft—called the Lynx—hasn't even been built yet, but about 40 people have already bought $90,000 tickets for rides on an early version. One of them, Anton Kriel, explained to British papers: "I will no longer have to listen to people who brag about their new Aston Martin."
One of the problems that the Concorde faced was its sonic "boom" whenever it broke the sound barrier, which tended to scare the heck out of residents down on earth. New technology could minimize the sound of the boom, allowing this new craft to fly above populated areas without frightening locals.
The Concorde flew 2.5 million passengers in its years of service.
Here's an (over-the-top) promotional video for the new two-hours-to-anywhere-flights:

Where seismic data is recorded in populated areas, it is common to have high-amplitude harmonic noise contaminating the data. This noise is produced by power transmission lines and other equipment and often has amplitudes several orders of magnitude higher than the amplitudes of desirable signals in the seismic data. The harmonic noise present in our data contaminates different parts of the spectrum and, therefore, simple notch filtering is not effective. We used a time-domain-based method of automatic estimation of noise frequencies and their amplitudes, followed by subtraction of these estimated anomalous harmonics from the data. Filtering reflection data from a transect across the Archean - Proterozoic terrane boundary in southern Wyoming and northern Colorado in this way significantly improved data quality even in areas where first breaks were completely obscured by the noise.

Scituate Reservoir Watershed
The largest fresh waterbody in Rhode Island, the Scituate Reservoir is the source of Providence Water’s supply. The Y-shaped reservoir is nearly 6 miles long and has a storage capacity of nearly 37 billion gallons at the Gainer Dam spillway elevation. Its average depth is about 32 feet, while it reaches a depth of 90 feet just upstream of the dam.
Water flows into the Scituate Reservoir from five smaller tributary reservoirs (Barden, Moswansicut, Ponaganset, Regulating, and Westconnaug) and an extensive network of rivers and smaller streams. In total, Providence Water owns surface reservoirs covering about 5,000 acres and another 13,000 acres of surrounding forestland.
Providence Water works to conserve the entire Scituate Reservoir watershed, or area of land that water flows across or under on its way to the main reservoir. The watershed is located primarily within the rural towns of Scituate, Foster, and Glocester, and also includes parts of western Cranston and Johnston. The total drainage area covers 93 square miles or nearly 60,000 acres.
Land use influences the water quality in the reservoir and private wells within the watershed. Maintaining forest cover and practicing and promoting wise stewardship help ensure cleaner water entering the reservoirs. Since Providence Water only owns about one third of the land in the watershed, it relies on local municipalities and private landowners as stewardship partners.
Protecting the source of the water supply saves ratepayers’ money by reducing treatment costs, while providing many other benefits.


What is a map service?
The map service is the way that you publish maps to the Web using ArcGIS. You'll make the map in ArcMap, then publish the map service to ArcGIS Server. Internet or intranet users can then use the map service in Web applications, ArcMap, ArcGIS Explorer, and other applications.
What can a map service do?
A map service makes maps, features, and attribute data available inside many types of client applications. ESRI provides .NET, Java, SOAP, and REST interfaces for working with map services. One common use of a map service is to show business data on top of basemap tiles from ArcGIS Online, Bing Maps, or Google Maps.
Additionally, when you publish the map service, you can choose to expose it through the KML or OGC WMS specifications. This can make your map service available to a broader variety of clients, such as Google Earth.
How do I start creating a map service?
All map services begin inside ArcMap, where you create your map. When you've finished the map and are ready to publish it, open the Map Service Publishing Toolbar. The items on the toolbar help you publish your map as a service. See Publishing a map service for full instructions.


Genetic testing for cystic fibrosis, fragile X syndrome and spinal muscular atrophy is recommended for all would-be parents by a study in Australia.
The research is based on data from the Victorian Clinical Genetics Services (VCGS) which began to offer genetic testing in 2012 for these common and severe disorders.
Researchers anaylsed screenings of 12,000 individuals, and discovered that about 5 percent of them - 610 - were carriers of these diseases. This rate is on par with the population risk for Down's syndrome, and supports the stance that people should be routinely tested for these conditions, they said. Of the carriers, 88 percent had no family history and had no reason to suspect they were carrying these genetic disorders.
'There is also a misconception that these types of disorders are only relevant where there is a family history of the condition...but most parents who have a child with one of these disorders have no family history,' said senior author Professor David Amor, who is at the VCGS and Murdoch Children's Research Institute.
Genetic screening is typically done before pregnancy, but can be done during the first 12 weeks of gestation. Couples who are carriers of cystic fibrosis or spinal muscular atrophy have a 25 percent chance of having a baby with that disorder. Women who are carriers of the fragile X syndrome have a 50 percent change of passing on that mutation.
'It's important that all carriers are given the option of genetic counselling so they can discuss the implications of their results with an expert,' said Dr Alison Archibald at the VCGS, and joint first study-author.
Professor Amor added: 'Some couples will decide that [carrier screening] is not for them…but we know from experience that a lot of couples want this type of information.'
The study was published in Genetics in Medicine.


Takin, national animal of Bhutan and you are going to see during your tour to Bhutan. Government from Bhutan is well preserving Takin in Thimpu as it is also associated with religious history and mythology. It is a very rare mammal with a thick neck and short muscular legs. It lives in groups and is found above 4000 meters on the north- western and far north eastern parts of the country. They feed on bamboo. The adult Takin can weigh over 200 kilogram. Their habitat range is from rocky, grass covered alpine zones to the forests with undergrowth of bamboos and Rhododendrons. They are strong, unique and distinct, perhaps making them considered as the national animal of Bhutan.

The takin has a rich Bhutanese mythology dating to the 15th century. A Tibetan saint by the name Drukpa Kunley (aka, “The Divine Madman”) is credited with creating the takin with unique features. The people of Bhutan requested that Drukpa Kunley perform a miracle before them. The saint agreed to do so provided he was fed for lunch: a whole cow and a whole goat. Once served, he devoured the food of both animals and left out the bones. He then took out the head of the goat and fixed it to the skeleton of the cow—with a snap, he created a live animal.

Most viruses take over the cell's replicative machinery. The cell dies after 1-2 days when it contains masses of virus particles and is unable to repair itself. The masses of virus particles appear as inclusion bodies by staining.
A common problem in diagnosis is that the tissue homogenate is toxic . If the toxicity is of viral origin the medium above the dying cells can usually be diluted at least one millionfold and then kill new cell cultures.

the relationship that exists between the two.
2.) Discuss why the process of perception is crucial to living creatures and
how our system prevents us from experiencing sensory overload.
3.) Explain the sequential chain of events precipitating perception. Specify
the key components to this sequence and explain each in detail.
4.) Compare and contrast materialism and dualism as two alternative philosophical
explanations for perceptual experience and specify the individuals associated
with each perspective.
5.) Discuss the relationship between perception and action. Explain why this
relationship is important and include any problems which may result.
6.) Discuss the important "real life" implications for the study
7.) Discuss the relationship between perceptual experience and reality.

Nurses are crucial to fighting climate change and protecting the health of patients, communities, and future generations. There are several simple (but meaningful) actions that nurses can take to support climate-friendly environments at work, in communities, and in daily life. And, as you expand your range of actions, there are many other ways you can move your leadership forward for larger impact.
Nurses can move forward in addressing climate change by:
- Increasing awareness on how climate change impacts health
- Supporting climate-friendly practices in healthcare and academic institutions
- Reducing the pollution created by your homes, buildings, and transportation
- Advocating for health-protective climate and clean energy policy.
- Joining with others in calling for urgent action on climate change.
This toolkit provides an online repository of tools, resources, and more to support your climate leadership. Also included are ideas, resources, and evidence-based communication tools to engage your colleagues and other health professionals in climate and health solutions. Check out the climate champion section to learn best practices with tips and ideas from other nurses who have successfully implemented initiatives and engaged communities and practice settings in promoting sustainable environments.


Barite is the primary, naturally occurring, barium-based mineral. Barium, atomic number 56, derives its name from Greek and means heavy. Barite is also known as baryte. The primary countries in which commercial deposits of barite are currently found are the United States, China, India and Morocco. Barite’s high density and chemical inertness make it an ideal mineral for many applications.
The chemical formula for barite is BaSO4. To be economically viable for extraction, barite usually needs to be the predominant material in a deposit. The types of deposits in which it is normally found include vein, residual, and bedded. Vein and residual deposits are of hydrothermal origin, while bedded deposits are sedimentary.
The overwhelming majority of the barite that is mined is used by the petroleum industry as a weighting material in the formulation of drilling mud. Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for high-pressure zones experienced during drilling, thus suppressing high formation pressures and preventing blowouts.


1. The problem statement, all variables and given/known data While at a country fair, you decide to ride the Ferris Wheel. Having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. To take your mind off your stomach, you wonder about the motion of the ride. You estimate the radius of the big wheel to be 15m, and you use your watch to find that each loop around takes 25s. a) What are your speed and magnitude of your acceleration? b) What is the ratio of your weight at the top of the ride to your weight while standing on the ground? c) What is the ratio of your weight at the bottom of the ride to your weight while standing on the ground? 2. Relevant equations where T= period, r=radius v = 2(pie)r/T a = v^2/r 3. The attempt at a solution For part a) I got v= 3.7699 m/s and a= 0.947 m/s^2 For part b) since we are dealing with a ferris wheel, the FBD has normal force and weight pointing in the downward direction at the top of the ferris wheel. Would the apparent weight, which is the normal force, be (note: I made the positive y coordinate pointing down so n and w are positive): n+w=ma n=ma-mg Wapp=m(a-g) and because Wtrue=mg Wapp/Wtrue= (m(a-g))/mg m's cancel so, (a-g)/g (0.947-9.8)/9.8 = -0.9 However, that number should be positive. So, I am assuming that it should not have been n=ma-mg BUT instead n=mg-ma so n=m(g-a) so that Wapp/Wtrue= (g-a)/g so the ratio is 0.9. IF SO, WHY would n= mg-ma??? for part c) I got n-mg=ma so n=mg + ma so Wapp/Wtrue= (g+a)/g so ratio= 1.1 PLEASE HELP this question is due tomorrow morning, so help asap would be GREATLY appreciated!


The Oman-based data artist Marcelo Duhalde has taken information from the CIA’s World Factbook and the Encyclopedia Britannica and used it to chart human life expectancy at birth.
Take a look at the bottom-right part of this chart for “life expectancy along history.” For the reference (from Wikipedia): “The Neolithic Age, Era, or Period, or New Stone Age, was a period in the development of human technology, beginning about 10,200 BC, … and ending between 4,500 and 2,000 BC.”
Therefore, in less than 10,000 – 8,000 years, human lifespan increased from 20 years to 71. Not too bad. But we should do better!


Search For A Disorder
This is an ill-defined syndrome with the primary features of facial weakness and limited ocular abduction, usually bilateral and nonprogresssive. Those who first described this entity in the 19th century, von Graefe and M√∂ebius, accepted only cases with facial diplegia and bilateral 6th nerve palsy. Since then, however, a large number of associated nerve palsies and systemic malformations have been reported. More than a third of patients have features of Duane’s syndrome. Beyond the oculomotor dysfunction, no ocular abnormalities are consistently associated.
A large number of neurological and skeletal anomalies have been reported in association with what is called M√∂ebius syndrome. Orofacial dysmorphism, limb malformations and other cranial nerve palsies are the most common. The lack of specific diagnostic criteria for this ‘syndrome’ may explain why many of these associations have been reported, and it is beyond the scope of this database to enumerate or document the validity of including coexistent malformations as part of the M√∂ebius sequence. A significant number of patients have more general motor and coordination disabilities. It is not unusual for young patients to have respiratory difficulties and to suffer an early demise. Necropsy findings often reveal diffuse brainstem pathology.
This is either a clinically heterogeneous disorder or a category with multiple disorders. Familial occurrence is uncommon and recurrence risk is generally higher among families with simple 6th and 7th nerve palsies suggesting that cases in which other major anomalies occur are more likely to be the result of environmentally-induced maldevelopment. Both autosomal dominant and autosomal recessive inheritance patterns have been reported in familial cases.
Based on the pattern of chromosomal aberrations found in a multigenerational family, it has been proposed that a locus for Moebius syndrome resides somewhere in 13q12.2-q13.

Legionnaires' disease is a lung infection. It is a form of pneumonia. It got its name after it struck at the American Legionnaires Convention in 1976.
This disease is caused by the bacterium Legionella pneumophilia in most cases. The bacteria are most often found in sources of standing water. It may be found in cooling towers, HVAC systems, and air conditioners.
Legionnaires' disease can be contracted by breathing water vapor from a standing water source that contains Legionella bacteria.

Chapter 7: Organisation and management (The role of management…
Line managers: have direct responsibility over people below them in the hierarchy of an organisation. They have the authority to give orders and to have their decisions put into effect in their department.
Staff managers tend to be very well-qualified experts. They often know more about their particular specialist subject than they do about running the business.

Schools (and many adults) introduce another barrier, which is a profound misunderstanding of what it means to be fluent in math and science (the misunderstanding is usually in the form of thinking that math and science are fact and pattern based, and that learning the facts and the patterns is what is required)This confused me. If science and maths were not about facts and pattern recognition, then what were they about?
- Alan Kay, Squeakland list reference
Short answer: Making better maps
Thoughts about teaching science and mathematics to young children
the maps "are always subject to improvement and rediscovery: they never completely represent the territory they are trying to map ..."Computers are seductive. I may have been focusing too much on motivation, or game making or programming as goals in themselves.
"... helping children actually do real science at the earliest possible ages is the best known way to help them move from simple beliefs in dogma to the more skeptical, empirically derived models of science"
"... as Piaget pointed out, it is best to think of children as thinking beings in their own right ..."
our culture is confusing and the science is often not central, it can easily be missed
Also, computers are marketed as productivity tools with applications that attempt to do it all for us. Is that the best thing for learning? Probably not, but its more seduction.
Alan Kay points out that science knowledge in particular is a more expansive goal, perhaps a better pathway to help young children. The goal is to find child appropriate ways of teaching science. Computers can help here but that is just one possibility.


Q: Why did the composer only compose while lying in bed?
A: Because he was composing sheet music!
Years ago, when composers wrote music, they would write the music on sheets of paper that the musicians could read and perform. This music written on sheets of paper is called sheet music. Lots of music is written now using computers programs such as Notion or Sibelius. (I do not write music and do not know anything about these programs.) For musicians to perform, the music is most often printed out in sheets, sheet music. There are probably musicians who use a computer or tablet to read their music.
Sheets, though, has another meaning. When you make your bed, you put sheets on your bed, along with pillows and blankets.
This joke is funny because of the different meanings of sheets–sheets for your bed and sheet music. I wouldn’t recommend, however, using bed sheets for writing music; it might be difficult for the performer to read the music!
If you would like to learn to read sheet music, you could start here:


Why do South America and Africa seem to fit together like puzzle pieces? Why do volcanoes and earthquakes cluster in belts that girdle the globe? Why are all the ocean basins extremely young? Plate tectonics — the unifying concept of geology answers these questions and many others by explaining the dynamic motions and interactions of Earth’s tectonic plates. Find out how scientists fit together the pieces of the plate-tectonic puzzle.
Some of the clearest images of the ocean floor come from space! This one of the Atlantic Ocean was made by a satellite that can detect subtle differences in the height of the ocean surface. Amazingly, the height reflects the topography of the sea floor.


After the American Revolution several patriotic societies sprang up to promote various political causes and economic interests. Among these were the Tammany societies, founded in New York, Philadelphia, and other cities. The societies took the name of a Delaware chief, Tamanend, who is said to have welcomed William Penn and to have signed with him the Treaty of Shakamaxon.
The Tammany Society, or Columbian Order of New York City, the only Tammany society to have a long life, was formed c.1786 and was incorporated in 1789. Divided into 13 tribes, corresponding to the 13 states, it had as its motto "Freedom Our Rock"; its rites and ceremonials were based on pseudo–Native American forms, and the titles of its officials were also pseudo–Native American. Although its activities were at first mostly social, ceremonial, and patriotic, the society gradually became the principal upholder of Jeffersonian politics in New York City.

The use of carved wooden ancestor and protective figures was widespread across the islands of Indonesia. Protective figures, now known as 'hampatong', were placed at entrances to their villages and communal longhouses. Each 'hampatong' was carved for a specific purpose and personified a particular spirit or deity. They were made and displayed to celebrate occasions such as a successful headhunting expedition or the funeral of an important person.
This figure of a woman standing on a pedestal is decorated in relief with an 'aso' (a kind of underworld dragon-dog representing the very powerful female spirits), stylised leaves and lotus flowers. In this case, her regalia comprises an elaborate headdress extending down her back and prestige necklace, bracelets and earrings. A small animal clings to the side of the pedestal at her feet and a serpent-like creature is grasped at the waist. The other hand clasps what is possibly a 'kris', or sword. Many 'hampatong' have aggressively exaggerated features such as bulging eyes, gaping mouths and long protruding tongues, but this one is more naturally rendered and exudes a calm and reflective quality.

After touring Senegal and Gambia, Cooper returned to Toronto to begin her MA degree. Her thesis, which began her career studying Black Canadian history, was a study of Black teachers in Ontario from 1850 to 1870.
In 2000, she completed a Ph.D. dissertation about the life of Henry Bibb, a fugitive slave from Kentucky, who became an abolitionist in Canada. As a result of this original research, Cooper was named a “Kentucky Colonel,” the Commonwealth of Kentucky’s highest award. In tandem with this award, the Canadian government recognized Cooper’s dissertation by designating Bibb a person of national historic significance.
The Hanging of Angélique: The Untold Story of Canadian Slavery and the Burning of Old Montréal (HarperCollins, 2006) is the result of years of Cooper’s original research. It is the first account of this story published in English, as well as the first history of slavery in Canada written in English. The Hanging of Angélique, based on Marie-Joseph Angélique‘s trial record, was shortlisted for the 2006 Governor General’s Literary Award nominations for non-fiction.

Management of serious incidents
- Emergency response plans
- Necessary information
- Managing serious incidents
- Communicating with news media
It is important that everyone who is involved in outdoor adventure-based programs accepts the possibility that there could be a serious incident or a fatality during their activities. Understanding the implications of such incidents, the planning which is required beforehand to effectively manage the difficult circumstances, and the actions which must be taken will help everyone involved in a traumatic event.
Death on a trip is usually cited as the worst scenario which outdoor leaders and party members will ever have to face. However, if not well managed, serious injuries, psychological problems or even delays in groups returning from activities can all have very serious consequences for organisations running outdoor activities and the individuals involved.
As in most things, dealing with serious incidents effectively relies on planning, and the level of detail required depends upon the activity itself, the nature of the organisation running the activity and the nature of the participants. Prudent and professional trip organisers consider potential scenarios to deal with the immediate requirements and the inevitable aftermath of a serious incident.

Bobby Jackson has received much recognition for engaging students in the classroom, including an award for “Texas history of the year.” A look at one very popular history teacher’s classroom:
He starts challenging kids’ expectations the first day of school. ‘We do a brainstorming activity where I put the kids on a timer and ask them to give their perceptions of a Texan. Then we talk about stereotypes, myths, and legends. I tell them that a lot of our stories could or could not be true. The kids need to know there’s more to every story.’ Then he stays as personal, passionate, and interactive as he can. He has his students write letters to Stephen F. Austin applying to be among the first three hundred colonists. He reenacts Gonzales, Goliad, and San Jacinto in his classroom. ‘I portray a survivor of the Battle of San Jacinto, Stephen Franklin Sparks, who lived and died in Rockport. He was sixteen when he fought for Ben Milam, and he ended up being the second-to-last survivor of the Texas Revolution to pass away. And he was just about their age when he did all this.’ When he gets to the 1919 hurricane, he plays interviews with aging eyewitnesses that he recorded as part of his master’s thesis at Corpus Christi State. He also tells the students his own family’s hurricane stories, all while dressed in a two-piece, striped bathing suit and straw boater that look like an outfit Buster Keaton would have worn to the beach.


Plant nutrient requirements
Use this tag for questions about the nutrients required by plants. A lack of certain nutrients can cause problems which often appear like disease. An over-abundance of certain nutrients can also cause problems and may even act like poisons (e.g. copper).
The most significant nutrients in terms of volume, are atmospheric (carbon & oxygen, absorbed from the air) and water (typically absorbed by roots from the soil). The remaining nutrients are all mineral nutrients and are typically absorbed from the growing medium:
- Primary Macro-nutrients (Nitrogen, Phosphorus, Potassium)
- Secondary Macro-nutrients (Calcium, Sulphur, Magnesium)
- Micro-nutrients (trace-minerals): Boron, Chlorine, Manganese, Iron, Zinc, Copper, Molybdenum, Nickel, Selenium, Sodium.
Note that most of these are listed by their elemental names. Most are poisonous in this form and can only be absorbed in their ionic form. E.g. Chloride ions rather than chlorine gas.

Floras & Field Guides
Published floras have traditionally been the main means of synthesizing information on the species of plants in an area—their habitats, phenology, classification, common names, and practical identification. The Herbarium has published three comprehensive floras: the Flora of Virginia, coauthored with Chris Ludwig and Johnny Townsend, the Flora of the Southern and Mid-Atlantic States, and the recently released Flora of the Southeastern United States. The Flora of Virginia has won several awards, including the Thomas Jefferson Award for Conservation.
Through these and other major accomplishments, the Herbarium and allied researchers are today viewed as primary sources for information on southeastern U.S plants—information that is a foundational tool used by botanists, foresters, horticulturists, conservationists, and students throughout the U.S.
In 2015, the UNC Carolina Apps Program teamed up with NCU Herbarium and NCBG staff to develop the iPhone/iPad application FloraQuest. This app allowed for mobile identification of over 7,000 plant species in a 14-state region through an interactive interface. In 2022, The Southeastern Flora Team, led by Alan Weakley and Michael Lee, developed plans to phase out FloraQuest with a new and improved flora app, working closely with collaborator Katie Gibson (developer of High Country flora apps). As of December 2022, this app is being tested in beta form by various users in the northeastern region of the FSUS (Virginia northward), and the app will be available for public use in spring of 2023.


KUSA - Researchers at Carnegie Mellon University say telomeres may predict our ability to fight off the common cold.
Telomeres are protective caps made of DNA proteins found on the ends of our cells' chromosomes.
A new study shows that the length of telomeres may predict risk for the common cold.
"If the DNA is your shoestring, the telomeres is the tip of your shoestring," 9NEWS Medical Expert Dr. John Torres said. "It's the end parts of the DNA that we didn't used to think much about, but now we're finding out that they actually have a lot of impact. The shorter they are in people the more likely they are to get colds."
If you seem to get colds more often than most people, just recognize that and be more careful. Try to boost your immune system through exercise and eating healthy foods. The research was published Tuesday in the Journal of the American Medical Association.


The bank messenger had a great deal of responsibility
The Bank of Montreal Rules and Regulations of 1817 stated that the messenger “shall be accountable for whatever may be entrusted to his charge and for all sums of money collected by him. He shall also be responsible to the bank or to the parties concerned, as the case may be, for all losses arising from his negligence, errors or omissions in performing the duties assigned to him.” In smaller branches, the duties of the messenger were taken on by the porter, who already had his own long list of responsibilities.
Over the years, the role of the messenger changed significantly. While they would sometimes be called on to deliver sensitive documents and securities that had to be dispatched quickly, they would more often be kept busy delivering mail within the branch, helping customers fill out paperwork or directing them to the right teller.


2010 is the year of the tiger, an Asian astrological sign known for its charisma and courageousness. Astrological tigers may be all around us, but two tiger sub-species have gone extinct since 1930, and many believe the South China Tiger is “functionally extinct” because it hasn’t been seen in 20 years. Even for the remaining five tiger subspecies—Sumatran, Bengal, Indochinese, Siberian, and Malayan—the prognosis isn’t good: the WWF recently announced that the 3,200 tigers living in the wild are among the most threatened creatures on Earth.
Wild tigers live in isolated pockets of jungle, usually inside wildlife refuges, in a handful of Asian countries. Tigers need a few things to survive: lots of prey like deer and pigs, water, and some dense vegetation. However, habitat encroachment has been epic in recent years and since 1900, tigers’ range has decreased by 95% (see a map here).
However, I doubt that these majestic animals will disappear entirely. Their size, beauty, and potential deadliness make them popular, and lucrative, zoo exhibits around the world. In China, thousands of the big cats live in cages on tiger “farms” where tourists can visit them and where (it’s been reported) tiger blood, bile, bones, paws, and other parts are harvested for the black market, for use in expensive traditional medicines. International regulations prohibit trafficking or selling any tiger parts, but China has lobbied for a suspension of the rule in the case of farmed tigers, arguing that the sale of legal tiger parts could reduce poaching and fund conservation efforts. So far, their appeals have been unsuccessful, and the black market in tiger parts continues to thrive. Like the Giant Panda, the tiger may go extinct in the wild, but its monetary value to zoos and the black market means it will likely be around for decades to come. To learn more about tigers and how to save them, check out the World Bank’s conservation program and comprehensive threat analysis here.


Swans Woodworking Classes
Our Swans class have started their Woodworking classes again! They carefully listened to the safety instructions and how to use the equipment, and popped on their safety goggles to protect their eyes.
The woodwork classes are fantastic for developing their hand-eye co-ordination, mathematics and problem-solving skills which was particularly present when measuring out square shapes on the rectangular piece of wood using a ruler!
When we began to use the saw, the children behaved wonderfully around the equipment, holding it with both hands to ensure full control of the tool and used the saw across the line. The class also looked at how to handle a hammer safely, and learnt about screws and nails, identifying the differences between them and when you would use them.
They all showed a brilliant display of teamwork, helping each other to complete the task!

The reconstructed house is typical of those during Polk’s childhood. The kitchen and house are authentically furnished with period pieces from the early 1800s. The visitor center features exhibits on the life and times of President Polk and a twenty-three minute film "Who is Polk?" tells of his accomplishments.
The Mecklenburg Chapter of the Daughters of the American Revolution erected a stone monument at the site in 1904. It was the first monument dedicated in North Carolina to the eleventh president. Special events commemorate Polk’s birthday in November and focus on eighteenth-century Christmas customs in December. Special programs and activities are planned for scheduled school groups upon request. Visitors are invited to take guided tours of the main house and kitchen which are provided throughout the day.

For many years, it has been speculated that adult tarpon migrate vast distances during their annual runs. Last week, the University of Miami (FL) publish the results of an 18-year long study which shows just how far adult tarpon move.
MIAMI—The results of an 18-year study of Atlantic tarpon by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science revealed that these large silvery fish take extensive seasonal migrations—1,000s of kilometers in distance—beyond U.S. borders. The new findings can help protect the fish, which is listed as vulnerable by the IUCN–International Union for Conservation of Nature, and the main draw of a more than $6 billion catch-and-release sportfishing industry in the United States.
Using electronic satellite tags, the UM research team tracked nearly 300 Atlantic tarpon (Megalops atlanticus) in coastal waters of the western central Atlantic Ocean, the Gulf of Mexico and the Caribbean Sea, including as far away as Mexico, Belize, and Nicaragua. The results showed that the mature tarpon make extensive seasonal migrations along a warm, seasonally moving ocean-water feature known as the 26o C isotherm where temperatures remain constant. They also found the fish use both freshwater and estuarine habitat throughout their life and identified several previously unknown spawning locations in Florida and the Gulf of Mexico.
“Our findings show that there is international connectivity in the U.S. multibillion-dollar recreational tarpon fishing industry,” said Jerry Ault, UM Rosenstiel School professor and a co-author of the study. “This is of great importance to anglers and scientists alike to better understand and protect this valuable—and vulnerable—fish and the people who rely on it.”

The Book of Daneil
Daniel was among the young men of noble birth who were taken captive in 606 B.C. by the Babylonians in their first of three invasions of southern Palestine. Daniel, whose name means “God is my judge,” lived through the entire 70-year period of exile. He witnessed the decline and fall of the mighty Babylonian Empire as well as the rise of the Medo-Persian Empire.
In addition to serving as God’s prophet, he also served as a powerful political leader under Nebuchadnezzar and Darius. His personal spirituality and dedication to God are seen in his serious prayer life and in his willingness to serve God regardless of the people or laws that were hostile toward him.
Like Ezekiel, Daniel focuses on God’s authority and power. (Indeed, “the Most High rules in the kingdom of men”—4:17,25,32; 5:21). God’s will and purposes cannot be thwarted. He will accomplish His intentions no matter what happens in human history. Daniel shows the importance of staying faithful even in tough situations.
God took care of His children (even in captivity), and He promised them the ultimate care of salvation in the future through Christ. In the book of Daniel the Jews are restored to their homeland after 70 years of captivity, but long-term spiritual restoration would come with Christ about 500 years later.

Emilie Griffin prunes apple and pear trees in anticipation of a good crop next year
When pruning apple and pear trees, you need to make sure they are dormant – from December to late February, between leaf fall and bud break.
The way you prune your fruit tree depends on whether it is tip- or spur-bearing. And to determine this you will need to know how it has fruited in previous years.
Tip-bearing trees tend to fruit on the tips of branches. However you can get a partial tip-bearer that fruits both on the tips and the spurs.
Spur-bearing trees produce small stubby sideshoots along the branches.
Step 4 for spur-bearing trees
Step 4 for tip-bearing trees
Previously fruited shoots will look as though they have a callus (repaired wound) at the tip


Padre Gaspar Ignacio de Guevarra was the parish priest of San Juan Nepomuceno in what is now the Municipality of Biliran around 1765-1774.The community he has built and led was said to be the earliest recorded settlement in the island of Biliran. Researches pointed out that Padre Gaspar led a religious revolt against the ruling Spanish regime. Upon his death, local folks accorded him the status of a saint, and continue to venerate his burial site.

This collection gathers all the stories that talk about changemaking. A changemaker is someone who is taking creative action to solve a social problem. And changemaking involves empathy, thoughtfulness, creativity, taking action and collaborative leadership. But although these skills are essential to our thriving, they are almost entirely absent from the educational experience of most young people, with often a narrowing focus on reading, maths and the acquisition of academic grades.
Ashoka's vision and mission, then is to catalyse the transformation of education systems so that every child and adolescent is provided with educational environments and experiences that are explicitly designed to ensure they become changemakers. Its strategy involves:
- finding and selecting a network of pioneering schools, entrepreneurs and other key actors that are alread putting changemaking at the heart of everything they do - and that have the leadership capacity to influence widely across the education system.
- Convening and organising these pioneers into Change Teams which will make sharply-focused, strategic moves that catalyse rapidly self-multiplying changes in education practice.
- Supporting and connecting each team to maximise their impact - with an emphasis on developing their capacity to build further teams and to lead change; finding oportunities to scale, building an internationally recognised movement; showcasing a new norm in education; and changing mindsets about the purpose, practice and policy of education.
For further information, please go to Ashoka changemakers page, which activates a global network of social entrepreneurs, innovators, business leaders, policy makers and activists to build the movement towards an Everyone A Changemaker world.


Leg pain while walking or doing other activities could be a sign of peripheral artery disease, an expert says.
Peripheral artery disease (PAD) develops silently, narrowing blood vessels until a shortfall in the supply of nutrients and oxygen causes cramps and leg pain, explained Dr. Faisal Aziz, chief of vascular surgery at Penn State Health Milton S. Hershey Medical Center.
“Pain with physical exertion is a classic, hallmark sign,” Aziz said in a Penn State Health news release. “When it gets really bad, it can form wounds on the legs that do not heal or cause blackening of the foot or toes.”
Risk factors for peripheral artery disease include age and gender. Men and all people 65 and older are most likely to develop the condition. Other risk factors include smoking, high blood pressure, high cholesterol, uncontrolled diabetes and heart disease.


Romero, backed by ultraconservatives, won an election wracked by bloodshed and clouded by accusations of voting fraud. A staunch anticommunist, he defended the use of military force to ensure political order. His inauguration was boycotted by the archbishop of San Salvador to protest the military’s treatment of the church. Dozens of priests had been killed, kidnapped, expelled, or arrested by the military since the Feb. 20, 1977, elections.
In 1978 Romero attempted to improve his administration’s image abroad by abrogating the hated Law of Defense and Public Order, but government repression continued, as did the protests of a populist coalition of workers, peasants, and students called the Popular Revolutionary Bloc. On May 18 Romero convened a national forum on the problem of violence, but, since he did not invite the Popular Bloc (which he had declared illegal), the forum was boycotted by the entire opposition, including political parties, labour unions, and the church. A general amnesty was declared on Aug. 16, 1979, but this move failed to avert violence.
Guerrillas assassinated his brother and, on September 23, attacked the president’s residence. The October 1979 coup against Romero was influenced by the fall of the government of Anastasio Somoza Debayle in Nicaragua. Romero was deposed by a group of younger military officers led by Col. Adolfo Arnoldo Majano Ramos, and Romero fled to Guatemala. On May 2, 1980, he backed an unsuccessful rightist coup against the military-civilian junta which had ruled since he was ousted from office.


Now, raising this issue, I know, is sensitive for many people and that the obstacles standing in the way of protecting the human rights of LGBT people rest on deeply held personal, political, cultural, and religious beliefs.....
The ... perhaps most challenging, issue arises when people cite religious or cultural values as a reason to violate or not to protect the human rights of LGBT citizens. This is not unlike the justification offered for violent practices towards women like honor killings, widow burning, or female genital mutilation. Some people still defend those practices as part of a cultural tradition. But violence toward women isn't cultural; it's criminal. Likewise with slavery, what was once justified as sanctioned by God is now properly reviled as an unconscionable violation of human rights.
In each of these cases, we came to learn that no practice or tradition trumps the human rights that belong to all of us. And this holds true for inflicting violence on LGBT people, criminalizing their status or behavior, expelling them from their families and communities, or tacitly or explicitly accepting their killing.
Of course, it bears noting that rarely are cultural and religious traditions and teachings actually in conflict with the protection of human rights. Indeed, our religion and our culture are sources of compassion and inspiration toward our fellow human beings.....LGBT rights advocates called the speech historic. (Dallas Voice.) The State Department also issued a Fact Sheet outlining more broadly its accomplishments in promoting LGBT human rights. Meanwhile at the White House yesterday, President Obama issued a Memorandum to executive departments and agencies (full text) "directing all agencies engaged abroad to ensure that U.S. diplomacy and foreign assistance promote and protect the human rights of LGBT persons."


Mosquito-Transmitted Chikungunya Virus Detected For First Time In Caribbean
“A nasty virus first detected in Africa that is spread to people by the bite of infected mosquitoes is being locally transmitted in the Americas for the first time on the tiny French Caribbean dependency of St. Martin, health officials said Tuesday,” the Associated Press reports. “Epidemiologists have so far confirmed about a dozen cases of locally acquired chikungunya virus in St. Martin,” but “[t]here are dozens more suspected cases,” the news agency writes. “On Tuesday, the [CDC] sent out a health advisory to doctors in the United States to consider chikungunya infection in patients with acute onset of fever and joint pain, ‘especially those who have recently traveled to the Caribbean,'” the AP notes. “Health officials on … the island are responding to the outbreak by reducing mosquito breeding sites, enhancing epidemiological surveillance and enlisting the help of the public to clear out stagnant water,” the news agency states (McFadden, 12/17).


Identification and containment are the goals for public health officials when it comes to dealing with a new coronavirus that originated in Wuhan, China, as the number of cases surged over the weekend.
But at this point in the outbreak, there are still more questions than answers about the virus, which causes respiratory illnesses like pneumonia.
tap here to see other videos from our team.
“This is primarily a virus of particular interest because it is a novel, new coronavirus and we don’t want it to become established in the human population. So we are very focused on the early identification of cases and trying to contain those,” said Dr. Danuta Skowronski, lead of the influenza and emerging respiratory pathogens team at the B.C. Centre for Disease Control.
There have been no confirmed cases of the coronavirus in Canada, although three people who had travelled to Wuhan were investigated as possibly having the virus, and were ruled out within the past week.


The Plain Whorl
The plain whorl consists of the simplest form of whorl construction
and is the most common of the whorl subdivisions. It is designated by
the symbol W for both general classification and extension purposes.
The plain whorl has two deltas and at least one ridge making a
complete circuit, which may be spiral, oval, circular, or any variant
of a circle. An imaginary line drawn between the two deltas must touch
or cross at least one of the recurving ridges within the inner pattern
area. A recurving ridge, however, which has an appendage connected
with it in the line of flow cannot be construed as a circuit. An
Figures 194 to 211 are typical examples of the plain whorl type.


Advances in cognitive science are leading to new knowledge of human language development and its underlying mechanisms. The contributions in this book apply recent advances in neurobiology, developmental neuropathology behavioral neurology, psycholinguistics, and computational models of learning and cognition to outstanding questions about the acquisition of language in humans, with special emphasis on dyslexia and related developmental disorders.
The formal approach to developmental disorders of cognition presented here promises to help answer outstanding questions about human linguistic disposition, language acquisition, developmental deviance, diversity, and breakdown.

1.1.L.33 Legal responsibility
This definition applies to all payments.
Legal responsibility is the right to have and to make decisions concerning the day-to-day care welfare and development of a child. Both parents are legally responsible for their child, except where:
- they agree that one parent should have greater or sole responsibility, or
- a court makes an order that changes their responsibility in a particular matter.
Example: Mr Brown and his ex-partner Ms Black have a court order which details the care arrangements of their children. The court order states that the children will have contact with their father on alternate weekends and half the school holidays as well as on Father's Day. The children are to have contact with their mother on Mother's Day. Legal responsibility for the children may be deemed to be joint as the court order does not specify otherwise.
When a person is granted sole custody of a child, then that person has the legal responsibility for the care, welfare and development of that child. The child is a dependent child (1.1.D.70) of that person, regardless of who has access to the child, if the child is in the person's care.

|area:highway = steps|
|An area representation of steps.|
|Used on these elements|
|Status: in use|
|Tools for this tag|
Some steps take up a significant areas - or mappers are interested in super-accurate mapping - so this tag was developed to precisely map this, in addition to highway=steps way tagged through their middle.
How to map
- If it's a simple steps area, just draw outline around it, and add tag area:highway=steps.
- If it's a more complicated one, draw an outline around it, draw all inner parts, then select all elements and make a multipolygon relation from it. Add tag area:highway=steps to multipolygon.
- Remember about joining area's edges to surrounding buildings, walls, etc.
Linear routable way
- Always create also a linear highway=steps way along the centerline of the area:highway=steps as described in area:highway=*


The Dutch Colonial Army was the main defense against the Japanese invading the Netherlands East Indies during World War II. In December 1941, Dutch forces in Indonesia numbered around 85,000 troops, a combination of European and indigenous regular soldiers, locally organized militia, territorial guard units and civilian volunteers.
March 20, 1602: The Dutch East India Company is founded. The Dutch East India Company (Vereenigde Oost-indische Compagnie) was founded through the sponsorship of the Dutch government, who granted it a monopoly over trade in the East Indies through a charter that was set to expire after twenty-one years. The company could, through this charter, build forts and conduct military and diplomatic activities in the area, which would help to protect and direct Dutch trade in the East Indies


This paper reports on what differentiates the field of soft (i.e. soft-bodied) robotics from the conventional hard (i.e. rigid-bodied) robotics. The main difference centres on seamlessly combining the actuation, sensing, motion transmission and conversion mechanism elements, electronics and power source into a continuum body that ideally holds the properties of morphological computation and programmable compliance (i.e. softness). Another difference is about the materials they are made of. While the hard robots are made of rigid materials such as metals and hard plastics with a bulk elastic modulus of as low as 1 GPa, the monolithic soft robots should be fabricated from soft and hard materials or from a strategic combination of them with a maximum elasticity modulus of 1 GPa. Soft smart materials with programmable mechanical, electrical and rheological properties, and conformable to additive manufacturing based on 3D printing are essential to realise soft robots. Selecting the actuation concept and its power source, which is the first and most important step in establishing a robot, determines the size, weight, performance of the soft robot, the type of sensors and their location, control algorithm, power requirement and its associated flexible and stretchable electronics. This paper outlines how crucial the soft materials are in realising the actuation concept, which can be inspired from animal and plant movements.


Prime Factors and Square Products
Date: 10/05/2003 at 15:59:25 From: Alexander Subject: Creating a square number What is the smallest number that you can multiply by 540 to make a square number? I know the answer is 15, which I found by trial and error. That is, I worked out the prime factors and they are 2^2, 3^2, and 5. Juggling these brings me to 90 x 90 = 8100, which is 540 x 15. What I cannot work out for numbers other than 540 is the correct method of juggling. My working was random and I'd love to be able to apply this to other numbers. Thanks.
Date: 10/05/2003 at 19:20:29 From: Doctor Luis Subject: Re: Creating a square number Hi Alexander, You were on the right track. The prime factorization of 540 is 540 = (2*2)*(3*3*3)*(5) = 2^2 * 3^3 * 5^1 Now, when you square a number, the exponents get multiplied by two. Therefore, the prime factors of a square number appear an even number of times. So, to make the product of 540 and something else a square number, you have to make the prime factors of the product appear an even number of times. You can see that there are already two 2's, so you don't worry about the 2. But there are three 3's and only one 5. That's why you need an extra 3 (so there are four instead of three) and an extra 5 (so you have two instead of just one). Of course, 3*5 = 15, which was your guess. 540 * (3*5) = 2^2 * 3^4 * 5^2 Since the exponents of the prime factors are all even, we can also find what number it squares 540 * 15 = 2^2 * 3^4 * 5^2 = (2 * 3^2 * 5)^2 = (10 * 9)^2 = 90^2 A square number, just like you wanted! Hopefully, you can now apply this method to numbers other than 540. Let us know if you have any more questions. - Doctor Luis, The Math Forum http://mathforum.org/dr.math/

Potato Bug / Jerusalem Cricket
|Potato Bug/Jerusalem Cricket|
Jerusalem crickets are found throughout the western United States, along the Pacific Coast, and south into Mexico. They can be introduced to worm bins when they are in yard waste which is fed to the system.
Believed by some to be fierce and poisonous, this nocturnal cricket is actually non-aggressive and possesses no poison glands, although its jaws can inflict a painful bite.
Potato Bugs have been found in worm bins but are usually found while preparing the ground for spring or winter planting, this insect never appears in large numbers and is not considered a pest that requires control. Their numbers are kept in check by birds and rodent predators, fly and worm parasites, curious cats and gardeners' hoses.
The Jerusalem cricket spends most of its life underground. Its large, almost humanoid head supports the necessary muscles that assist the jaws in digging in the soil and feeding on living and dead plant materials. Like most crickets, this insect also produces sound, called drumming, by hitting its spiny legs against its body.
Jerusalem crickets complete a generation within a year, beginning with the hatching of eggs in the spring and the development of adults by fall.
WE DO NOT SELL Jerusalem crickets


Yanomamo is an ecological musical for soloists, chorus, narrator and musical accompaniment.
Yanomamo vividly tells of the destruction of the Amazon Rainforest and its effect on the Yanomamo, the oldest Indian tribe living there. They lead a way of life in harmony with nature which, undisturbed, would survive with the forest indefinitely. However, their existence, and that of millions of animals and plant species, is threatened by the arrival of outsiders who assume that the forest soil is permanently rich and that once the trees are cleared, the land will be very productive. But after two years, no crops will grow because the richness of the jungle is in the trees, not in the soil.
The delicate balance of nature is being systematically removed and soon the rainforests, which are crucial to the world's eco-system, will disappear together with the Indians and the wildlife. Is there the time or the will to save them?
Yanomamo was filmed as Song Of The Forest and shown in Channel 4's Fragile Earth series, narrated by Sting.

While working for the FDR administration in 1936, photographer Dorothea Lange took the following photograph:
You’ve likely seen it before…it’s called Migrant Mother and it’s one of the more famous American photos. When she took the photo, Lange neglected to note the woman’s name (or other details) so her identity remained anonymous while the photo went on to become a symbol of the Great Depression. In the late 1970s, Florence Owens Thompson revealed herself to be the woman in the photo after she wrote a letter to her local paper saying that she didn’t like the image. In an AP story about the ensuing flap, Thompson stated:
I wish she hadn’t taken my picture. I can’t get a penny out of it. [Lange] didn’t ask my name. She said she wouldn’t sell the pictures. She said she’d send me a copy. She never did.”
In addition to not taking her subject’s name, Lange got something else wrong. Thompson and her family weren’t typical Depression migrants at all; they’d been living in California for almost 10 years. Like all photographs, Migrant Mother is neither truth nor fiction but somewhere in-between.
