Cannabinoid hyperemesis syndrome (CHS) is recurrent nausea, vomiting, and cramping abdominal pain that can occur due to prolonged, high-dose cannabis use. These symptoms may be relieved temporarily by taking a hot shower or bath. Complications may include kidney failure and electrolyte problems, and the condition can be fatal if not properly managed.
|Cannabinoid hyperemesis syndrome (CHS)|
|People with CHS often find some relief with hot baths or showers|
|Symptoms||Nausea, vomiting, stomach pain|
|Causes||Long term cannabis use|
|Diagnostic method||Based on the symptoms|
|Differential diagnosis||Cyclical vomiting syndrome|
|Treatment||Cannabis cessation, hot baths and showers|
Weekly cannabis use is generally required for the syndrome to occur; synthetic cannabinoids can also cause CHS. The underlying mechanism is unclear, with several possibilities proposed. Diagnosis is based on the symptoms, as well as the history of cannabis use (including a urine screen test if necessary). The condition is typically present for some time before the diagnosis is made. Another condition that presents similarly is cyclic vomiting syndrome (CVS).
The only known effective treatment for CHS is to stop using cannabis. Two weeks (or possibly more) may be required to see a benefit. The primary differentiation between CHS and CVS is that cessation of cannabis use only relieves CHS.
The syndrome was first described in 2004, and simplified diagnostic criteria were published in 2009.

The Late Bronze Age (c. 1500-1200 BC) was a period of international trade relations between the Mediterranean world and the Near East. The trade connected and saw the exchange of goods from Central Asia to the middle Mediterranean. The nexus of this trade was the Levantine coast where ships moved luxury goods such as ivory, perfumes, copper, tine, bronzes, glass, precious stones, wine, oils, and other objects. The Uluburun shipwreck is an example of the types of ships and contained the types of cargo exemplary of this trade.

French nationalist historian best known for his monumental Histoire de France (1833–67). Michelet’s method, an attempt to resurrect the past by immersing his own personality in his narrative, resulted in a historical synthesis of great dramatic power. Michelet was the son of a modest printer who managed to give Jules an education. A brilliant student, Michelet at 29 was teaching history and philosophy at the École Normale Supérieure. He had already published textbooks and a translation (1827) of Giambattista Vico’s Scienza nuova (“New Science”). The July Revolution (1830) confirmed Vico’s influence on Michelet in stressing man’s own part in the making of history, conceived as a continuous struggle of human freedom against fatality. This, the main theme of the Introduction à l’histoire universelle (1831), was to underlie Michelet’s later writings. After the Histoire romaine, 2 vol. (1831), Michelet devoted himself to medieval and modern history; his appointment as head of the...

Reflexive pronoun denotes the reflected action upon the subject like a mirror which is done by that subject. Reflexive pronoun is a type of pronoun. It refers back to the subject of a sentence that is noun, pronoun, adjective or adverb.
These are referred to the subject used as object of a verb.
Reflexives are formed by adding -self to singular and –selves to plural personal pronouns.
There are eight reflexive pronouns in English.
Let’s have a look-
Examples of Reflexive Pronoun
We can see that we have used reflexives in the following examples.
We can use these in singular as well as plural form.
Singular Number Plural Number I educate myself. We educate ourselves. You educate yourself. You educate yourselves. He educates himself. They educate themselves. She educates himself. They educate themselves. It educates himself. They educate themselves.
In above sentences,

Hiram Rhodes Revels (September 27, 1827 – January 16, 1901) was the first African American to serve in the United States Senate. Because he preceded any African American in the House, he was the first African American in the U.S. Congress as well. He represented Mississippi in 1870 and 1871 during Reconstruction. As of 2011, Revels is one of only six African Americans ever to have served in the United States Senate.
Revels was born free in Fayetteville, North Carolina, of a free father of mixed white and black ancestry, and a white mother of Scottish heritage. He was tutored by a black woman for his early education. In 1838 he went to live with his brother, Elias B. Revels, in Lincolnton, North Carolina, and was apprenticed as a barber in his brother's shop. Elias Revels died in 1841, and his widow Mary turned over her assets to Hiram before she remarried.
Revels attended the Union County Quaker Seminary in Indiana, and from 1856–57, Knox College in Galesburg, Illinois. He also studied at a black seminary in Ohio. Revels was ordained a minister in 1845. As a minister in the African Methodist Episcopal Church, Revels preached in Indiana, Illinois, Ohio, Tennessee, Missouri, Kansas and Maryland in the 1850s. "At times, I met with a great deal of opposition," he later recalled. "I was imprisoned in Missouri in 1854 for preaching the gospel to Negroes, though I was never subjected to violence." In 1845 he became a minister in Baltimore, Maryland, and set up a private school.


The vast majority of the world’s youth are literate: 87 percent of young women and 92 percent of young men have basic reading and writing skills.
168 million child labor workers aged 5 to 17. This is one reason many children cannot attend school.
Conflict and natural disasters have disrupted the education of 75 million children.
What does #QualityEducation mean as a goal?
We have a couple of targets that we are trying to hit by 2030, the world’s major deadline. Meaning, if we hit them, we achieve the overall goal.
1.) Every child gets 12 years of education.
By 2030, ensure that all girls and boys complete free, equitable and quality primary and secondary education leading to relevant and effective learning outcomes.
2.) Equal access to education for all.
By 2030, eliminate gender disparities in education and ensure equal access to all levels of education and vocational training for the vulnerable, including persons with disabilities, indigenous peoples and children in vulnerable situations.
3.) Your education gets you employed.
By 2030, ensure that all men and women, in particular, the poor and the vulnerable, have equal rights to economic resources, as well as access to basic services, ownership and control over land and other forms of property, inheritance, natural resources, appropriate new technology and financial services, including microfinance.

Sheath mite injury showing up on white pine
Sheath mites can cause misshaped needles on white pine. Here are some tips on scouting for them.
of white pine sheath mite, Setoptus
spp (Acari: Eriophyidae), involves two distinctly different phases of activity.
Now as the candles are elongating, mites inhabit the needle sheath and feed on
the elongating needles. This causes the needles and the new growth to be
stunted or curled. The mites feed openly on mature needles, causing them to
turn yellow and later turn brown, die and drop off, leaving naked branch tips.
This damage can mimic other problems such as environmental or nutritional
issues and herbicide injury, and needs to be taken into consideration when
diagnosing the problem.
To check if you are having a problem with these tiny mites, look inside the needle sheath at the base of the needles. You may need to pull the needles apart in order to see the mites. They are very small and you will need a hand lens (15 to 20X) or microscope to see them. They are creamy white and about 1/125 of an inch (0.2 mm) in length. Their bodies gradually taper toward the end and are somewhat shaped like a carrot.
Most trees usually support small populations that cause no visible damage. Flare-ups often occur on stressed trees or after applications of broad spectrum insecticides that kill mite predators.


The United States is a representative democracy where people vote for politicians to govern on their behalf – but voting in the direct democracy of ancient Athens was a very different process.
Academy of American Democracy
Created in partnership with the New York Historical Society as part of their Academy of American Democracy project, this series looks at the links between the roots of democracy in ancient Athens and modern day democracy in the USA
We often think of ancient Greek society as White, but it was a lot more diverse than we give it credit for.
How do elections actually work in the United States?
The lives and rights of women in Greece, from a modern perspective, seem severely limited; yet, they played important roles in society.
In ancient Athens, symbols were used to promote religious and democratic ideals and beliefs. Thousands of years later these symbols helped to define the United States.
Greece was home to hundreds of open-air arenas where citizens came together to discuss the important issues of the day. Like Broadway today, they were a place for both entertainment and important social commentary.
What forms of government preceded democracy and how did this pave the way for the ancient Athenians to invent democracy?
Citizenship allows people to participate in the democratic process, but the road to inclusive citizenship has not been a smooth one.
How the The Stonewall Inn became the focus of the LGBTQ+ community’s fight for rights in the 1960s
Why are public spaces – places that are open to everyone, where people can gather – necessary for democracy?


Post-traumatic stress disorder (PTSD) is a mental health condition that's triggered by a terrifying event. Symptoms typically start within three months of that event. In a small number of cases though, PTSD symptoms may not appear until years later. Symptoms may include flashbacks, nightmares, and severe anxiety, as well as uncontrollable thoughts about the event.
Many people who go through traumatic events have difficulty adjusting and coping for a while. But with time and taking care of yourself, such traumatic reactions usually get better. In some cases though, the symptoms can get worse or last for months or even years. Sometimes they may completely shake up your life. In a case such as this, you may have post-traumatic stress disorder. Getting treatment as soon as possible after post-traumatic stress disorder symptoms develop may prevent long-term PTSD.
People of all ages can have post-traumatic stress disorder. However, some factors may make you more likely to develop PTSD after a traumatic event, including:
• Experiencing intense or long-lasting trauma
• Having experienced other trauma earlier in life
• Having other mental health problems, such as anxiety or depression
• Lacking a good support system of family and friends
• Having first-degree relatives with mental health problems, including PTSD
• Having first-degree relatives with depression
• Having been abused or neglected as a child


Powering Homes in Denmark with Surplus Heat
Meet the team behind this innovation. From left to right: Peter Sorensen, Steen Blenstrup, Bo Hoeg Olesen, Jorgen C. Kock and Henry Beck Hansen
DuPont Nutrition & Health in Grindsted, Denmark was screening possible energy saving projects for its site when it discovered a major potential win-win. During the production phase at the Grindsted plant, surplus heat was wasted in cooling towers. The energy team decided to make better use of this surplus heat by distributing it to the Grindsted Electricity and Heating Plant (GEV). GEV delivers heat and electricity to private households and other buildings in Grindsted where it is used for water and space heating during winter. District heating is common in most cities in Denmark as they are densely populated with little sprawl. This makes it possible to produce heat efficiently at combined heat and power plants and subsequently supply this to customers through a network of insulated pipes. The result of the project was an estimated heat energy supply to GEV of 12,627 megawatt hours (MWh), which is enough to power 900 homes in the community. This generated savings of 1,200,000 normal cubic meters (Nm3) in natural gas in GEV and 195 MWh electricity at the Grindsted plant.
In terms of carbon footprint, this is equivalent to a reduction of 2,700 tons (MT) of carbon dioxide at GEV and 70 tons carbon dioxide at the Grindsted site. The case shows that it is possible to find win-wins for both the economy and the environment. Furthermore, it is an example of industrial symbiosis where a by-product, initially perceived as waste, in one company can be turned into a valuable resource input for another company.


Although Escher did not have mathematical training—his understanding of mathematics was largely visual and intuitive—his art had a strong mathematical component, and several of the worlds that he drew were built around impossible objects. After 1924, Escher turned to sketching landscapes in Italy and Corsica with irregular perspectives that are impossible in natural form. His first print of an impossible reality was Still Life and Street (1937); impossible stairs and multiple visual and gravitational perspectives feature in popular works such as Relativity (1953). House of Stairs (1951) attracted the interest of the mathematician Roger Penrose and his father, the biologist Lionel Penrose. In 1956, they published a paper, "Impossible Objects: A Special Type of Visual Illusion" and later sent Escher a copy. Escher replied, admiring the Penroses' continuously rising flights of steps, and enclosed a print of Ascending and Descending (1960). The paper also contained the tribar or Penrose triangle, which Escher used repeatedly in his lithograph of a building that appears to function as a perpetual motion machine, Waterfall (1961).


Department of Chemistry
Chemistry is a discipline that lies at the heart of the natural sciences, whose goal is to create new substances by transforming molecular structures and to explore the structure, properties, and reactivity of those substances. This goal is what drives the Department of Chemistry. Because the applications of modern chemistry are so broad and diverse, including the development of chemical materials and materials used in electronic devices, as well as other applications in space, the life sciences, and the environment, this department has established three separate research programs in inorganic and analytical chemistries, organic chemistry and biochemistry, and physical chemistry to support a wide range of academic pursuits. The graduate school cultivates researchers and engineers who are equipped with advanced knowledge in cutting-edge fields of chemistry, grounded in a deep level of expertise, as well as a broader, more comprehensive sense of judgment that goes beyond their field of specialization.

Premenstrual syndrome (PMS) is a combination of emotional, physical, psychological, and mood disturbances that occur after a woman's ovulation and normally end with the onset of her menstrual flow.
It is thought that PMS may be caused by hormonal changes (fluctuations in oestrogen and progesterone) that occur during the menstrual cycle.
The most common mood-related symptoms are irritability, depression, crying, oversensitivity, and mood swings with alternating sadness and anger.
The most common physical symptoms are fatigue, bloating, breast tenderness (mastalgia), acne and appetite changes with food cravings.
PMS is also known as late luteal phase dysphoric disorder.
The mood changes surrounding this condition have been described as early as the time of the ancient Greeks. However, it was not until 1931 that this disorder was officially recognised by the medical community. The term "premenstrual syndrome" was coined in 1953.


Scientists in Oregon and Washington State are reporting the development and successful testing of a new method for determining the extent of illicit drug use in entire communities from water flushed down toilets that enters municipal wastewater treatment plants.
The technique may be an effective tool for comparing drug use in different regions of the United States and the world, they note in a study is scheduled for the December 15 issue of ACS' Environmental Science & Technology, a semi-monthly journal.
In the study, Aurea C. Chiaia and colleagues note that the new test eliminates the need for sample preparation — saving time and money and decreasing the risk of sample contamination. They proved the test's effectiveness by measured levels of illegal drugs like methamphetamine and legal drugs like prescription painkillers in wastewater from seven U.S. municipalities. The research team also tested the levels of 'urine indicators' such as creatinine, a metabolic byproduct that can be used as an indicator of drug use.
The scientists determined the 'index loads' of the different drugs — the amount of drug per person per day —based on estimates of the population served by each wastewater facility. These calculated index loads generally reflect known illegal drug use patterns in the US and worldwide. The loads for methamphetamine in western and southern U.S. were much larger than previous reports from Europe, for example.
The authors proposed that urine indicator compounds like creatinine could be used in place of population estimates — which can fluctuate and be unreliable — to determine more accurate community-level drug index loads, which can then be compared between municipalities.

Category:Peeragogy Handbook V1.0
Peeragogy is a framework of techniques for peer learning and peer production. As pedagogy theoretically articulates the transmission of knowledge from teachers to students, peeragogy describes the way peers produce and utilize knowledge together. We have been working together as a volunteer team since January, 2012 to build a public domain Peeragogy Handbook that communicates practical strategies for successful collaboration, learning, and adaptation. We see Wikimedia as a living case study in peeragogy. In the six-month project we propose, we would use peeragogical methods to enhance Wikimedia as a peer-learning platform.

NASA's Chandra Delivers New Insight into Formation of Star Clusters
Using data from NASA’s Chandra X-ray Observatory and infrared telescopes, astronomers have made an important advance in the understanding of how clusters of stars come into being.
The data show early notions of how star clusters are formed cannot be correct. The simplest idea is stars form into clusters when a giant cloud of gas and dust condenses. The center of the cloud pulls in material from its surroundings until it becomes dense enough to trigger star formation. This process occurs in the center of the cloud first, implying that the stars in the middle of the cluster form first and, therefore, are the oldest.
However, the latest data from Chandra suggest something else is happening. Researchers studied two clusters where sun-like stars currently are forming – NGC 2024, located in the center of the Flame Nebula, and the Orion Nebula Cluster. From this study, they discovered the stars on the outskirts of the clusters actually are the oldest.

In light of Alex Trebeck’s death there has been a national conversation on pancreatic cancer. According to the National Institutes of Health, roughly 47,000 deaths this year have been due to pancreatic cancer, and there have been roughly 58,000 new cases of pancreatic cancer confirmed this year.
Pancreatic cancer is caused by the formation of malignant cells (cancer cells) in the tissues of the pancreas.
So who is at risk? Individuals older than 45 years old, both males and females (but especially males), people of color, persons with Ashkenazi Jewish heritage, individuals who are very overweight, have a family history of pancreatic cancer or pancreatitis (inflammation of the pancreas), personal history of diabetes or chronic pancreatitis, smoke or have a history of smoking, or hereditarily conditions such as multiple endocrine neoplasia type 1 (MEN1) syndrome, hereditary nonpolyposis colon cancer (HNPCC; Lynch syndrome), von Hippel-Lindau syndrome, Peutz-Jeghers syndrome, hereditary breast and ovarian cancer syndrome, familial atypical multiple mole melanoma (FAMMM) syndrome, or ataxia-telangiectasia, according to the National Institutes of Health.
The signs and symptoms of pancreatic cancer are mild in the first stages, which makes diagnosis difficult. However, the National Institutes of Health states that the signs and symptoms to watch out for can include: jaundice (yellowing of the skin and whites of the eyes), light-colored stools, dark urine, pain in the upper or middle abdomen and back, weight loss for no known reason, loss of appetite, and/or feeling very tired.
However, there are preventive strategies individuals can use to prevent their chances of getting pancreatic cancer. They include avoiding smoking, managing your diet, weight, and physical activity, and avoiding alcohol use, as well as limiting exposure to certain chemicals.

This project examined the skeletal remains of a 3, 000-year-o/d preagricultural population to determine whether a sexual division of labor existed. Cortical bone remodels itself throughout an individual's lifetime in response to the stresses experienced by activity patterns. Cortical bone morphology, therefore, discloses the nature of the stresses caused by different activity patterns. Computer tomography was used to obtain femoral cross-sections for 30 females and 34 males, taken at two levels along the diaphysis of the bone in order to determine the direction from which the major bending stresses are created. Student's t-tests and Analysis of Variance were used to analyze the differences in means and variances of the ratios for the sexes. The statistical tests revealed that two of the four ratios showed a significant difference between males and females. It is suggested that males were doing more traveling than were females. Females were probably participating in food preparation close to a home base.

Cybersecurity needs for the government, businesses and other parts of society are constantly growing, making cybersecurity training and education a vital need. There is a distinct lack of skilled and trained workers in this specialty area. “Teaching Cybersecurity Using the Cloud”, a technical paper from the IEEE Xplore® Digital Library, explores a solution to this problem that utilizes a cloud computing system to conduct a course for students on cybersecurity.
Teaching students about cybersecurity involves more than reading from a textbook and learning about theories. Students must also have practical and hands-on experiences dealing with cybersecurity threats. The article authors used cloud computing through Amazon Web Services to teach a senior course on cybersecurity across two campuses in a virtual classroom with live audio and video. They studied how cloud-based laboratory exercises could teach students the skills they would need to pursue a career in cybersecurity.
The goal of the course was to expose students to modern network security issues, protocols and technologies, as well as analyzing security solutions and countermeasures. The students were able to learn and perform lab activities all within the cloud. This cloud model of learning can enable students to gain invaluable cybersecurity skills, without having to be at a specific location. In turn, this way of teaching can help to educate more students, without the need for a traditional classroom and lab setup, leading to a growing workforce of cybersecurity experts.

The human ear is sensitive and delicate and can detect very small changes in sound pressure. Loud noise, whether continuous or impulse, can cause permanent damage to the ear and result in hearing loss.
Many countries have legislation in place to protect workers at risk of being exposed to dangerously loud noise, usually deemed to be 90dB(A) and above. In welding and allied industries noise levels are likely to exceed these, and it is often difficult to engineer a reduction in noise.
Hearing protection, in the form of ear plugs and ear muffs, is available and must be worn in noisy areas if workers are to prevent themselves suffering noise induced industrial deafness.


The pharynx -- the throat -- may be one of the most underappreciated organs in the body. This muscular tube is not only an integral part of both the digestive and respiratory systems, but it is also in contact with four body cavities. The pharynx produces antibodies when exposed to antigens, serves as the resonating chamber in speech production, and assists with hearing. Additionally, it contributes to balance and sense of taste.
The pharynx is a hollow, primarily muscular tube with moist, mucus-rich walls. It rests behind the mouth and the nasal cavity, between the larynx and the esophagus. It measures about 5 inches long, starting at the base of the skull and extending to the upper esophageal sphincter. Circular muscles called constrictors make up its outer layer. These muscles aid in the swallowing process by cutting off air passageways to prevent aspiration of food. Longitudinal muscles lie beneath the pharynx's outer layer of muscles, consisting of three flexible outer bands which aid in shortening and widening the pharynx during the swallowing process.

Clarity is determined by measuring the water depth at which an 8-inch diameter white disk disappears from view. The Lake owes it extraordinary natural clarity mainly to its exceptional depth and volume, a relatively small watershed and favorable climatological conditions. In 2013, clarity averaged 70.1 feet, far less than the maximum 105 feet of clarity measured in 1968. In the last 10 years, the rate of loss of clarity has decreased due to environmental improvements in the watershed.

matched pair study
Case-control studies are often used to investigate causes of health conditions that are serious and rare. This is because other study designs, such as randomized studies, would need to be very large to have enough statistical power to detect an effect.
Case-control studies are also sometimes undertaken to evaluate effects that are subsequently confirmed by other studies.
For example, a comparison of people admitted to hospital with heart attacks (cases) with others admitted with different diagnoses found that the people with heart attacks were less likely to have used aspirin. The apparent protective effect of aspirin against heart attack was subsequently confirmed in randomized studies.

NCD Global Monitoring Framework
Ensuring progress on noncommunicable diseases in countries
Following the Political Declaration on Noncommunicable Diseases (NCDs) adopted by the UN General Assembly in 2011, WHO developed a global monitoring framework to enable global tracking of progress in preventing and controlling major noncommunicable diseases - cardiovascular disease, cancer, chronic lung diseases and diabetes - and their key risk factors.
NCD targets and indicators
The framework targets and indicators
The framework comprises nine global targets and 25 indicators and will be up for adoption by Member States during the World Health Assembly in May 2013. Once adopted, Member States are encouraged to consider the development of national NCD targets and indicators building on the global framework.
The 9 voluntary global targets are aimed at combatting global mortality from the four main NCDs, accelerating action against the leading risk factors for NCDs and strengthening national health system responses. The mortality target - a 25% reduction in premature mortality from noncommunicable diseases by 2025 - has already been adopted by the World Health Assembly in May 2012.
The framework goals
The framework is expected to drive progress in prevention and control of NCDs and provide the foundation for advocacy, raising awareness, reinforcing political commitment and promoting global action to tackle these deadly diseases. The framework will also help shape a new development agenda that advances the three dimensions of sustainable development: economic development, environmental sustainability, and social inclusion.
NCDs are the leading cause of death in the world. The four main noncommunicable diseases - cardiovascular disease, cancer, chronic lung diseases and diabetes - kill three in five people worldwide. Premature deaths from NCDs, however, can be prevented by changed policies and active engagement not only in health but also in other sectors. Effective action will save millions of lives and avoid suffering.


Political unrest leads to peril for Madagascar's lemurs
Madagascar's lemurs are facing a crisis, the result of a perfect storm of factors that have left them perilously close to extinction. Our colleague Robyn Dixon reports on the damage that's been done, and what one Madagascan scientist-turned-spy is doing to try to repair it; here's an excerpt:
There are dozens of lemur species in Madagascar, 99 at last count, some of them not much bigger than a mouse, most of them critically endangered. The largest lemurs are most vulnerable, because they need more food.
Environmentalists predict that Madagascar will be the next Haiti, a country suffering catastrophic deforestation and environmental degradation because of poor governance.
The lemurs face multiple threats.
In some parts of the country they're considered bad luck, which means that villagers kill them on sight. In other parts, where they're not taboo, they're hunted for food.
Climate change and deforestation are leaving the landscape parched and are destroying habitats.
Logging mafias, alleged to have close links to the government and to Chinese traders, bribe or threaten overstretched, poorly paid park rangers and take precious timber, with devastating results.
The current government was installed in March by the military, which toppled President Marc Ravalomanana and replaced him with his rival, Andry Rajoelina, then the mayor of the capital, Antananarivo. Negotiations on a power-sharing compromise have stalled.
The U.S., the European Union and the World Bank responded to the coup by imposing sanctions, including suspension of USAID's environmental programs. USAID, the U.S. State Department's development agency, had been supporting the Ministry of the Environment, Water, Forests and Tourism, helping the country protect its forests and fauna.

Enterobacteriaceae is a family of bacteria commonly found in the human gut. There are several species of bacteria within the Enterobacteriaceae family, which include but are not limited to Escherichia, Klebsiella, Enterobacter, Salmonella, Shigella, Citrobacter and Yersinia. Many species of Enterobacteriaceae are necessary for digestion and are usually harmless when contained in the gut.
CRE stands for carbapenem-resistant Enterobacteriaceae. Specifically, three species of the Enterobacteriaceae family - Klebsiella, Enterobacter and Escherichia - have developed resistance to a group of antibiotics called carbapenems. Carbapenems are often used as the last line of treatment when other antibiotics are not effective in treating Enterobacteriaceae infections.

What are the basic themes in the poetry of John Ashbery?
1 Answer | Add Yours
John Ashbery's poetry is mainly about the play and process of the mind interacting with the world. This is his largest theme, arguably as demonstrated in masterpieces such as "The System" and "Flow Chart." In the system we see Ashbery's mind reach out and try and interpret life, love, perspective, and reality. This long poem is an enigma and offer many a literary theorist with ripe matter for mining. It is more of an expression of the mind in action as it reaches out, embraces, then contemplates anything that is "outside" of the mind. Ashbery is also concerned with the process of artistic creation and appreciation. "Self Portrait in a Convex Mirror" is one such a poem, amongst others. Since he is an art critic amongst other roles, he often writes about painting and the act of inspiration and creation. His themes are numerous since the mind perceiving subjects is numerous. Other themes include: love, loss, alienation, the everyday, painting, art, emotions, homoeroticism, emotions, etc.

Yesterday morning started well as the students prepared for the 8th grade writing assessment. While I can’t elaborate upon yesterday’s topic or any other specifics, I didn’t hear any student complain about it being difficult. That is certainly promising! I just hope that everyone did their best and feels proud of his or her work.
After the testing, the students began the basics of our next unit, which will be focused on the students producing researched-based assignments. They worked to present questions that they had about a couple of segments in MythBusters. They then recorded the answer they figured out by watching those exact segments which focused on how to escape a sinking car (how do you escape a car that is sinking underwater?) or on the 7-Paper fold myth (can you fold a sheet of paper more than 7 times?). Some students in my 7th period started trying to bust the 7-Paper Fold myth on their own.

Londyn Lewis Coloring Pages May 02, 2022 07:33:14
Problems with hyperactivity and attention deficit disorders, as well as attention deficit hyperactivity disorder, also known as ADHD, are diminished, psychologists believe, in children who devote a good portion of their time to coloring pages.
As already stated that alphabet coloring pages are specially designed for preschool children, however they can also be used for toddlers, kindergarten students, and also for first grade students who are little slow in learning.
Such images on the pages reinforce letter and numeric figure recognition and also improve writing skills.
The world of web has been really delightful in these matters.
Coloring pages have been around for many years, but with the ever-evolving technology that we are all so in awe of, it is the high-tech games and toys that generally catch the attention of parents, while the advantages that coloring pages have to offer very young or even elementary age children, are ignored.
In order for a child to be happy and develop well, the role that parents play is extremely critical.


1. For instance, applicants with Computer Science degrees would not only be qualified for jobs in high-tech companies, they would also be well prepared for any job with computer skills as a prerequisite.
2. A good education is supposed to include everything from languages to mathematics to science, etc.
3. A well-rounded education leads to well-balanced people, which in turn leads to a tolerant, knowledgeable society.
4. There are a great many children thinking the main purpose of education should be to afford them pleasure and enjoyment. (注意there be句型后的名词再加动词不能用原形。)

1. Jackie Chan once told that when he was still a teenager, he and his partners were required to practice more than 12 hours a day; and it was said Jet Li was sent to be an apprentice when he was hardly four years old.
2. Bill Gates, as we know, dropping out from university when he found the possibility of earning money in a new massive market - personal computer market. As a result, he succeeded.
3. Steven Jobs found Apple company when he was young, and when his business reached the peak, he was fired by directors of board. However he never lost hope and didn't give up. Jobs set up a new company named Pixar and made several famous animation movies. Finally when Pixar was bought by Apple, Jobs returned to Apple.

Queen gives Canadian Museum for Human Rights a piece of history
Published Saturday, July 3, 2010 10:56AM CST
Queen Elizabeth II is using the Winnipeg stop on her Canadian tour to unveil the cornerstone of the Canadian Museum for Human Rights, which was crafted with a piece of British history.
Charles Brunet, a third generation craftsman with Brunet Monuments carved the cornerstone of the museum to incorporate a stone from the ruins of the St. Mary's Priory near Windsor, where some believe the Magna Carta was signed. The stone was a gift from the Queen.
Brunet has carved out piece of Tyndall stone to create a space where the St. Mary's stone rests, covered and protected by sandblasted and etched glass.
The local craftsman said he appreciates the work done centuries ago on the historic stone.
"What I really particularly enjoy seeing in this piece is the chisel marks the holes drilled here and there, you wonder what has gone on over the years," Brunet said.
Patrick O'Reilly, the chief operating officer of the Canadian Museum for Human Rights said that while the St. Mary's stone is literally a cornerstone for the new museum, it has symbolic significance as well.
"That her majesty has decided to grace us with her presence is one thing, but then to bring this incredible gift – metaphorically it's a cornerstone for human rights and that's amazing."
Brunet said the stone is tied to the beginning of human rights in the English-speaking world.
"This stone was present when King John signed the Magna Carta in 1215," Brunet said. "It's a real honour and a privilege to touch this stone. We realize how important this stone is for all of Winnipeg and Manitoba."
The stone will remain on public display at the legislature until the museum officially opens in 2012.

About the book
A new book focusing on the world’s most important charnel sites goes on sale this month, examining morbid masterpieces of art created from human remains between the 16th–19th centuries.
During this period great charnel houses were built on consecrated ground to preserve the bones of the dead which had been disinterred to make room for the newly buried, and it was widely believed that they would be resurrected and clothed in divine glory at the Second Coming of Christ.
The 224-page hardback book is written by Paul Koudounaris, who spent three years visiting 18 countries to see the phenomenen for himself – from the crypts of the Capuchin monasteries in Italy to the ossuary in Évora in Portugal. The book is richly illustrated with modern and archive images.
The Empire of Death: A Cultural History of Ossuaries and Charnel Houses by Paul Koudounaris is published by Thames & Hudson on 17 October 2011, priced at £29.95. For more information, visit the Thames & Hudson website.

Delivered as eight lectures before the University of Oxford, Edwin Hatch’s The Organization of the Early Christian Churches is an engrossing historical account of the formation of ecclesiastical polity. Addressing such controversies as the secular influence within the creation of the early church as well as adopting systems already engaged by civil organizations of the time, Hatch’s lectures have been an integral and contentious resource for early Church historians and theologians.

About Edwin Hatch
Edwin Hatch (1835–1889) studied at Cambridge and then graduated from Pembroke College at Oxford University. Ordained in 1859, Hatch proceeded to teach at a number of schools and universities, including Trinity College in Toronto and Oxford University, where he returned as vice-principal of St. Mary Hall. A noted theologian and scholar, his books regularly provoked controversy and criticism.


The purpose of this project is to scope the potential of phytostabilisation – planting designed to keep materials in place - as an environmentally sensitive, inclusive and low-cost strategy that will allow for an enhanced social resilience in the face of food insecurity and economic precariousness (keeping roads working) while at the same time enhancing the ecological resilience of much needed arable lands (designing roadsides that mediate erosion and can potentially even become productive in their own right) and the long-term social resilience of communities that are precariously connected via these roads.
This foundation-building project brings together a range of expertise to produce a cohesive inter-disciplinary strategy for enhancing a ‘slow’, socio-ecological resilience by engaging social arts and public pedagogies with environmental sciences to help bridge the gap between immediate needs and sustainable futures. This dynamic involves an engagement with: 1. Public and community based pedagogies to understand and educate those involved in the possibilities, requirements, and implications; 2. The arts to engage social imaginations of alternative futures, civic belonging, and community cohesion; 3. Geochemistry, engineering, and agronomy to ensure the appropriate and effective design of techniques and selection of organisms; 4. Geopolitics and environmental governance as a means of envisioning the broad social, political and cross-border contexts within which these can be proffered; and 5. Community, cross-cultural, and multimodal facilitation.

Fort Ringgold Post Cemetery
Starr Co. TX
The Ringgold Barracks Post Cemetery had fifty US
colored troops who died there in 1865. Before 1874, these bodies were removed
from Fort Ringgold to the Brownsville National Cemetery. In 1911, a total of 146
bodies (16 unknown) were moved to the Alexandria (Louisiana) National Cemetery.
Bivouac of the Dead by Mark Hughes.
And in 1947, the remains of the abandoned Fort Ringgold Post Cemetery were reinterred at the San Antonio National Cemetery. The name was in honor of Bvt. Maj. Samuel Ringgold, the first United States Army officer to die from wounds received in the battle of Palo Alto (May 8, 1846); he died on May 11. Handbook of Texas online.


Radical New Theory Could Kill the Multiverse Hypothesis by Natalie Wolchover.
Though galaxies look larger than atoms and elephants appear to outweigh ants, some physicists have begun to suspect that size differences are illusory. Perhaps the fundamental description of the universe does not include the concepts of “mass” and “length,” implying that at its core, nature lacks a sense of scale.
This little-explored idea, known as scale symmetry, constitutes a radical departure from long-standing assumptions about how elementary particles acquire their properties. But it has recently emerged as a common theme of numerous talks and papers by respected particle physicists. With their field stuck at a nasty impasse, the researchers have returned to the master equations that describe the known particles and their interactions, and are asking: What happens when you erase the terms in the equations having to do with mass and length?

Centres of Gravity
Every body has a point through which the whole mass of the body can be considered to act. If the body is held tat the centre of gravity it will not move or tilt. If the body is suspended from some arbitrary point, the centre of gravity will hang below the point of suspension. This is illustrated below for the triangular piece of card CDE suspended by a string AB. The centre of gravity is at O, vertically below AB.
The centre of gravity of an object can be found by suspending an object from two different points.
The centre of gravity can be found from the intersection of the lines PQ and XY when the pictures of the chair are superimposed. Notice the centre of gravity does not have to be inside the chair.
If the vertical through the centre of gravity lies outside the base then an object will topple. This is illustrated below. The objects in pictures 1 to 3 are stable but the object in picture 4 will topple.
Notice the difference between pitures 3 and 4. The centre of gravity of the object on the right is higher than for the one on the kleft. When they are both tilted through an ever increasing angle, the object on the right will topple before the object on the left. It's centre of gravity is higher so it is less stable.


THE AUSTRALIAN Government is investing $2.12 million for specialist scientists to investigate Australia’s unique array of plants and animals through taxonomic research.
The Australian Biological Resources Study’s National Taxonomy Research Grant Programme is a competitive, merit-based process led by an External Expert Assessment Panel of seven taxonomy experts. Taxonomy – the science of naming, describing and classifying organisms to include all plants, animals and microorganisms – will help fill large gaps in current knowledge and possibly open up new innovation across a braod spectrum.
A spokesperson for Parks Australia, the body which administers the National Taxonomy Research Grant Programme, said research in taxonomy was vital for biodiversity conservation, particularly within Australia’s Commonwealth reserve estate.
“The discovery and documentation of Australia’s biodiversity can have many applications including: the recovery and management of threatened species; identifying and understanding the risks of pest species or vectors of pathogens to people, plants and animals; and the potential for discovery of novel new biological resources with medicinal or other properties,” the spokesperson said.
“Taxonomy is an important and often overlooked branch of science.
“Taxonomists’ work to describe and classify plants and animals which supports many areas of biology, ecology and conservation science.”
This year the panel assessed 83 applications and selected 19 projects to receive funding over the next three years.
“These 19 research projects will help us fill gaps in our current knowledge and understanding of Australia’s unique and incredibly rich biodiversity and will support the study of a wide variety of Australian species including millipedes, frogs, and everlasting daisies,” the spokesperson said.
“In previous years this funding has enabled researchers to discover and describe thousands of new species including algae, insects, plants and reptiles.”

The geological history of the surficial units of the Seaford East Quadrangle and the Delaware portion of the Seaford West Quadrangle was the result of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to sea-level fluctuations during the Pleistocene. The geology reflects this complex history by the cut and fill geometry of the middle and late Pleistocene deposits incised into the Beaverdam Formation. The geology is further complicated by periglacial activity that produced dune deposits and the Carolina Bays in the map area, which modified the land surface.

Our Model Of The Solar System Has Been Wrong This Entire Time!
If you walk into any classroom today, and likely ever since you were a kid yourself , there is one model being taught regarding the structure of our Solar System. It’s the model that looks like this:
It’s the traditional orbiting model of the Solar System, or the Heliocentric Model, where our planets rotate around the sun.
While this isn’t entirely wrong, it’s omitting one very important fact. The sun isn’t stationary. The sun is actually travelling at extremely fast speeds, upward of 828,000 km/hr, or 514,000 miles an hour.
Our whole Solar System is orbiting the Milky Way Galaxy. In fact it takes 220-Million Years for the Sun to orbit our Galaxy.
Knowing this to be true, our visual model of the Solar System needs to change, and has been inaccurate this whole time. In fact, our planets are barreling through space with the sun, and literally creating a giant Cosmic DNA Helix, and a vortex similar to our Milky Way Galaxy.
Like this but in space, creating a never ending Sine Wave;
This entails that our Sun & the Planets of our Solar System are never in the same place. When we make one rotation around the sun, we have already traveled millions of miles through space, meaning these Cosmic Cycles are far grander than we might have previously imagined.
Here are two video examples of the Helical Model of our Solar System:
This is one by Physicist Nassim Haramein, which clarifies the difference;
Here is a beautiful digital representation of how our solar system is actually a vortex;

After entering someone’s body—usually via the eyes, nose or mouth—the influenza virus begins hijacking human cells in the nose and throat to make copies of itself. The overwhelming viral hoard triggers a strong response from the immune system, which sends battalions of white blood cells, antibodies and inflammatory molecules to eliminate the threat. T cells attack and destroy tissue harboring the virus, particularly in the respiratory tract and lungs where the virus tends to take hold. In most healthy adults this process works, and they recover within days or weeks. But sometimes the immune system’s reaction is too strong, destroying so much tissue in the lungs that they can no longer deliver enough oxygen to the blood, resulting in hypoxia and death.

What Does Mortgagee Insurance Mean?
Mortgagee insurance refers to a policy that is included when a person gets a loan from a financial institution such as a bank to buy a property. The policy is for the lending institution’s protection and is meant to retrieve the property in case of dispute.
Insuranceopedia Explains Mortgagee Insurance
When a person borrows money from the bank to buy a property, they might also be forced to buy and sign a mortgagee policy. The policy can also be included as a provision in the papers that they have signed to get the loan. In this case, it becomes a mortgagee clause.
It is there to recognize the name of the lender. It also gives the lender the power over the property once the borrower fails to fulfill his or her financial obligations to the former.


Dark matter makes up more than 80 percent of the matter in the universe. But up until now, it’s eluded scientists. Yesterday, however, NASA announced a possible breakthrough. A particle detector mounted on the International Space Station may have detected dark matter. Theoretical physicist Michio Kaku explains.
From a very young age, we’re told to be honest, to tell the truth, and not to cheat. In most cases, we know when we’re breaking those rules. But in others, it’s not always so clear. Take, for example, journalism in the digital age.
The New York Times’ latest technological gadget is the haikubot, a poetry-seeking piece of software engineering that combs the text of every New York Times article as it’s published in search of the 5-7-5 syllable pattern that identifies a haiku.
Think about this: Nearly 15 percent of people aged 71 or older, about 3.8 million people, have dementia. By 2040, that number will balloon to 9.1 million people. And costs are expected to rise accordingly.
Technology can turn dry reporting into poetry and can revolutionize newsrooms, but it can drive us crazy — and make us less unproductive too. Evgeny Morozov says the trouble might not be in the technology itself, but how we think about it.

Polymers are macromolecules that consist of building blocks called monomers.
There are two methods by which polymers are made:
- Addition polymerisation
- Condensation polymerisation
In addition polymerisation, alkenes add to themselves. As this addition proceeds further a long molecular chain is formed. The alkene is the repeating unit in the chain (the monomer). The chain itself is the polymer.
If ethene is allowed to add to itself by the breaking open of the double bond, the polymer polyethene is formed.
In condensation polymerisation the addition of two monomers releases a small molecule, usually water.
In the formation of Polyester the two monomers used are ethane-1,2-diol and benzene-1,4-dicarboxylic acid. When these add, an ester link is formed and water is released:
Proteins and polypeptides are to be found in living organisms. Polypeptides are formed by a condensation polymerisation reaction between two amino acids. These two amino acids join by a peptide link and release a water molecule.
Polypeptides and proteins consist of long chains of amino acids.
Hydrolysis of a protein involves breaking the peptide link by a reaction with water.

The main objective of this session is to help you perform snow and ice removal duties safely to prevent accidents, injuries, or illness. By the time this session is over, you will be able to recognize snow and ice removal hazards; inspect equipment properly and use it safely; avoid slips, trips, and falls; shovel and lift safely to prevent back injuries; remove snow safely from roofs; and understand and prevent cold-related illness.
Why “Snow and Ice Removal Safety” Matters:
Whether your job duties involve snow and ice removal tasks during the winter months or you are clearing snow and ice around your own home, you need to work safely to prevent accidents and injuries. There are quite a few potential hazards involved in snow and ice removal—some you may already know about and others that you may not have been aware of.
- Snow and ice removal operation can be hazardous unless you take proper precautions to protect your safety and health.
- Operate all equipment safely as you have been trained to do and wear appropriate personal protective equipment (PPE).
- Shovel and lift safely, and be extra careful when removing snow from roofs.
- Dress warmly and watch for signs of cold-related illness and fatigue.
- Do not use drugs or alcohol on the job or before coming to work.


The Brisbane Cricket Ground
, commonly known as The Gabba
, — Cricinfo
is a major sports stadium
, the capital of Queensland
. It is named after the suburb of Woolloongabba
, in which it is located.
The land on which the ground sits was first set aside for use as a cricket ground
in 1895. The first cricket match was held on the site on 19 December 1896 between Parliament and The Press. The Gabba was not used for interstate or international cricket until 1931. The first Sheffield Shield match scheduled for The Gabba was to be played between 31 January 1931 and 4 February 1931. However, it was washed out without the captains' even bothering to toss a coin. The first cricket Test
match at The Gabba was played between Australia
and South Africa
between 27 November and 3 December 1931.
Over the years, The Gabba has hosted athletics
, Australian rules football
, cricket, cycling
, rugby league
, rugby union
and greyhound races
Between 1993 and 2005, The Gabba was redeveloped in six stages at a cost of A$128,000,000. The dimensions of the playing field
are now 170.6 metres (east-west) by 149.9 metres (north-south). The seating capacity
of the ground is now 42,000. In its appearance the Gabba now almost resembles a mini Melbourne Cricket Ground
complete with light towers and a gigantic modern grandstand ringing the ground providing an intimidating and noisy atmosphere for visiting......

Fixed Bridges - Bay Shore
A bridge replaces a missing tooth or teeth. It is called a fixed bridge because it is not removable.
A bridge is a structure, supported by teeth on either side of a space.
It spans the gap between teeth, just as a bridge spans a river.
How is a bridge made?
The first step is to prepare the supports for the bridge.
Replacement crowns are placed over existing teeth as supports for a bridge.
The dentist pares down the teeth on either side of the gap, and takes an impression of the prepared teeth.
This is then sent to the dental technician where the bridge is made.
The technician will make a replacement crown for each prepared tooth.
These crowns are joined to an artificial tooth, which replaces the missing tooth.
dentist will then cement the completed bridge over the prepared teeth.
How will my pared down teeth be protected until I receive my bridge?
The dentist will make and install a temporary acrylic bridge that will protect the teeth and prevent sensitivity.
You can eat normally with a temporary bridge. It will also look good.


Direct-writing systems will be leading the future of additive manufacturing in that they have simple and cost-effective processes. There are various types of direct-writing systems, such as the roll-to-roll (R2R), microdispensing deposition write (MDDW), maskless mesoscale materials deposition (M3D), and ink-jet systems. These technologies are being used for the production of radio frequency identification tags (RFIDs), organic light-emitting diodes (OLEDs), light-emitting diodes (LEDs), flexible electronics, solar cells, antennas, etc. Recently, the standardization of printing materials and equipment has become a key issue in the printed electronics industry. The standardization of printed electronics can be categorized into four parts: equipment, materials, testing methods, and the education of this technology.


Homophobia forces us to act "macho" if we are a man or "feminine" if we are a woman. This limits our individuality and self-expression.
Homophobia puts pressure on straight people to act aggressively and angrily towards LGBTQ people.
Homophobia makes it hard to be close friends with someone of the same sex.
Homophobia often strains family and community relationships.
Homophobia causes youth to become sexually active before they are ready in order to prove they are "normal." This can lead to an increase in unwanted pregnancies and STDs.
Homophobia prevents vital information on sex and sexuality to be taught in schools. Without this information, youth are putting themselves at a greater risk for HIV and other STDs.
Homophobia can be used to hurt a straight person if they "appear to be gay."
Homophobia makes it hard for straight people and LGBTQ people to be friends.
Homophobia along with racism, sexism, classism, etc. makes it hard to put an end to AIDS.
Homophobia makes it hard to appreciate true diversity and the unique traits that are not mainstream or "normal."

Primary Pollutants of Concern
Poor air quality often affects Sequoia and Kings Canyon National Parks, especially during summer. Ozone and particulate matter 2.5 microns and smaller (PM2.5) are the most harmful pollutants here. In summer months, ground level ozone and PM2.5 often exceed federal health standards, which are described using the Air Quality Index (AQI). The AQI was developed by the Environmental Protection Agency (EPA) for air quality communications and has color-coded categories that provide health statements based on measured pollutants in a given area.
This dial represents the current condition Air Quality Index (AQI) for the Sequoia and Kings Canyon National Parks reporting area. Also included on this air quality outlook is the pollutant that is contributing most to the AQI condition. To see the ratings for both ozone and PM 2.5, an air quality map for California, plus a two-day forecast, please visit AirNow website info for Three Rivers, California.
Understanding Air Quality Data
Looking For Respite From Poor Air Quality?
For higher elevations above 8,500 feet (2,438 meters), these areas typically retain good air quality even when lower-elevation monitors show poor air quality. Additionally, some days with poor air quality will have moments of healthier air. Daily and regional weather patterns may cause conditions to change rapidly so checking monitors for hourly pollutant patterns can help inform activities during your visit.

Every effort must be made to integrate the child with nystagmus into a normal school setting in order to prepare the child for adult life, even if cosmetic concerns may instinctively lead the parent to want to protect the child.
Diagnosis of nystagmus is made primarily by patient history as reported by a parent, the age of onset, and observation of any accompanying signs such as a head turn, tilt or tremor, or oscillopsia.
A periodic alternating nystagmus (PAN) is observed in primary gaze when the patient is looking straight ahead and is characterized by eye movements that continuously change direction and speed.
Children with nystagmus who have their the null point located at a position in which the eyes are positioned inward may develop an esotropia, a form of strabismus or eye turn.
Chiari II malformation: Impaired swallowing and gag reflex, loss of the breathing reflex, facial paralysis, uncontrolled eye movements (nystagmus), impaired balance and gait.
Other causes of acquired nystagmus are Arnold-Chiari malformations, vitamin deficiencies, syphilis, Wernicke's encephalopathy, Behcet's syndrome, and Meniere's disease.
Children with nystagmus are not aware that they may have a visual deficiency and as they get older must be helped with the restrictions that nystagmus places on them.
Drugs called GABA agonists, such as baclofen and carbamazepine, are useful in treatment of seesaw nystagmus and PAN, if the nystagmus is acquired and not congenital.
There is some reason to believe that a peculiar condition found in the majority of human albinoes, and known as nystagmus, is correlated with the absence of pigment in the central nervous system.
In complete human albinoes, albinism is correlated, in addition to nystagmus, with a peculiar roughness of the skin, making it harsh to the touch.


Disease surveillance and Burden
Assessing the health and economic impact of disease on a given population is the first step towards prioritization and adoption of appropriate vaccination policies and disease control strategies.
After a vaccine has been introduced, assessing the impact of vaccination on disease is an effective way to measure progress, guide programme development and advocate for continuing program support.
These impact assessments require reliable data on disease burden, measured by indicators such as morbidity and mortality rates, and collected through ongoing surveillance and reporting activities.
This section includes general as well as disease-specific information and guidance on methods for:
- Surveillance for Vaccine Preventable Diseases (VPDs)
- Morbidity and Mortality estimates (disease burden)
- Laboratory Networks

Liver organoids are functional 3D in vitro model consisting of native hepatic cell types. They are widely used as a platform to answer research questions ranging from hepatic development and regeneration, detoxification and metabolism studies, liver disease modelling, and adult stem cell biology. Liver organoids preserve the key physiological features of the liver and are composed of spherical monolayer epithelium. They are obtained through isolation and expansion of stem and progenitor cells from liver stem cell niches.
In a recent study, researchers from Switzerland have developed a new chemically defined stable and non-immunogenic matrix that supports the growth of human liver organoids. It is a potential breakthrough for current treatments against non-alcoholic fatty liver disease but also a crucial step in future transplantations.

Now I will show you how to draw bricks. This lesson will be very simple, at the same time very useful for you.
In this lesson, you will train your ability to make smooth, straight lines and gain useful skills that will be useful to you in the future. You will learn how to draw bricks and use this in your next drawings.
For example, you can easily draw a house that is made of bricks, or you can use brickwork for decorative purposes. Drawing bricks is very easy. It is enough to remember the sequence of steps and make straight lines.
In the picture, you can see that the brick wall consists of horizontal and vertical lines that are interconnected in a certain way. Make sure that there is the same distance between the rows of bricks and that all bricks are the same size.
- Coloring supplies
Time needed: 15 minutes.
How to Draw Bricks
- Draw the frame.
Determine what size your drawing will be and draw an even square.
- Add the first row of bricks.
Determine the height of the bricks and draw a horizontal line across the top of the frame.
- Depict the next row of bricks.
Draw another straight line as in the previous step.
- Add the next row of bricks.
Repeat the previous step and draw a straight horizontal line below.
- Continue adding rows of bricks.
Sketch out another straight line at the same distance.
- Finish drawing the horizontal lines.
At this stage, depict the last horizontal line.
- Start drawing the side outlines of the bricks.
Draw short vertical lines between the top rows.
- Add side outlines at the bottom of the frame.
Repeat the previous step and depict the same vertical lines at the bottom of the frame.
- Color the bricks.
You will need brown.
For your convenience, I have prepared a PDF file with a short version of the lesson. Download the file and enjoy drawing at any convenient time.

Allegheny Energy Supply Company (a subsidiary of FirstEnergy Corporation) have closed the coal-ash landfill for the former R. Paul Smith coal-fired power plant, located in West Virginia, based on the recent ruling by the West Virginia Department of Environmental Protection that environmental monitoring at the landfill could end.
The coal-ash had been used in cement manufacturing for the past 20 years. Mon Power, (another subsidiary of FirstEnergy Corporation) plans to build a 6MW Solar Facility at the 26-acre site as part of their plan to construct five utility-scale solar facilities in West Virginia, totaling 50 MW of renewable generation.
The R. Paul Smith coal-fired power plant was located in Maryland, between the Potomac River and the Chesapeake and Ohio Canal – north of Lock 44, but its coal-ash landfill was across the Potomac River in West Virginia, which explains why the West Virginia Department of Environmental Protection was involved. The 116 MW power plant was commissioned in 1927 and decommissioned in 2012. Efforts to close the landfill began in 2015. The landfill’s closure was the conclusion of a 20-year effort to reuse the plant’s coal-ash byproduct in cement manufacturing, harvesting 3.1 million tons of the coal-ash.


A home schooling parent lists the attitudes toward technology he tried to impart to his eighth grader:
Every new technology will bite back. The more powerful its gifts, the more powerfully it can be abused. Look for its costs.
Technologies improve so fast you should postpone getting anything you need until the last second. Get comfortable with the fact that anything you buy is already obsolete.
Before you can master a device, program or invention, it will be superseded; you will always be a beginner. Get good at it.
Be suspicious of any technology that requires walls. If you can fix it, modify it or hack it yourself, that is a good sign.
The proper response to a stupid technology is to make a better one, just as the proper response to a stupid idea is not to outlaw it but to replace it with a better idea.
Every technology is biased by its embedded defaults: what does it assume?
Nobody has any idea of what a new invention will really be good for. The crucial question is, what happens when everyone has one?
The older the technology, the more likely it will continue to be useful.
Find the minimum amount of technology that will maximize your options.

Resource-oriented systems provide an interaction mechanism that is based on resources and simple operations that use HTTP methods.
The most representative model for a resource-oriented system is the REST model, combined for example with XML. The objects inside this model have a set of attributes that are related to their state. To invoke methods on the target system (communication mechanism), you must use the standard HTTP methods such as GET, POST, PUT, and so on, and follow some conventions.
You can consider the following when you develop plug-ins for resource-oriented systems.
If you use REST or only HTTP with XML, you get one or more XML schema files to be able to read and write messages. From these schemas, you can generate a set of classes that define the object model. This set of classes only defines the state of the objects because the operations are defined implicitly with the HTTP methods, for example, as defined in the vCloud Director plug-in, or explicitly with some specific XML messages, such as the Cisco UCSM plug-in.
You need to implement the communication mechanism in another set of classes. This set of classes defines a new object model that interacts with the original object model. The object model for the communication mechanism consists of objects and methods only.
You can expose both the original object model and the object model for the communication mechanism inside Orchestrator. This might add some complexity depending on how both object models are exposed, and on whether you are merging related objects from both sides (to simulate an object-oriented system) or keeping them separate.


There's no truer statement than the old adage "you can't control the weather." You can't even predict it with complete certainty. As advanced as our meteorological forecasting techniques are these days, weather systems are changeable forces of nature. They can come on quickly, switch direction without notice and build in intensity in a short period of time. Whether you're at home, on foot, in your car or at work, a winter snowstorm can catch you off guard.
The National Snow and Ice Data Center defines a blizzard as a "violent winter storm, lasting at least 3 hours, which combines below freezing temperatures and very strong wind laden with blowing snow that reduces visibility to less than 1 km."
If a blizzard is bad enough, snow plows and salt trucks won't even brave the elements. Roads become desolate ice paths, businesses shut down, schools close and grocery stores get picked clean. If your home loses power and you have no backup heating system in place, your very life becomes at risk. In this article, we'll give you 10 tips on how to survive a snowstorm.


WHEN it comes to the cosmos, gravity is the big attraction. The same force that keeps our feet on the ground also shapes the universe. It takes clouds of gas and sculpts them into planets and stars. It fashions hundreds of billions of stars into galaxies, which clump together to form clusters, then superclusters. Yet gravity isn’t the only player in the game – another force operates across the cosmic landscape, and that is magnetism.
Magnetic fields stretch for vast distances in the near-nothingness of deep space, even spanning the billions of light years between galaxies. Admittedly, these fields are feeble. A fridge magnet is more than a million times stronger than the weak, all-pervading sea of magnetism in the Milky Way and beyond. That might explain why cosmology has largely ignored magnetism. After all, how could something so puny influence a galaxy?
Times and minds are changing, however. Yes, gravity holds things together, but key physical processes in the universe need magnetism – from star formation to black holes pumping out high-energy jets. “It turns out that many previously unsolved problems in astronomy suddenly make sense once one includes the effects of interstellar magnetism,” says Bryan Gaensler of the University of Sydney in Australia.
Could the same be true for the universe at large? What makes fields on the galactic scale and beyond so enticing is that they appear to be the legacy of processes that happened shortly after the big bang. What’s more, most of the visible …

A Land Cover Atlas of the United Kingdom (Document)
journal contributionposted on 03.11.2017, 16:42 by Alasdair Rae
This Atlas accompanies a much larger set of maps, published simultaneously here on Figshare. In the map set, there is one map for each local authority in the United Kingdom.
This report provides an introduction to the project, explains what Corine data is and provides an overview of land cover in the United Kingdom. It also looks a little more closely at land cover in England, Northern Ireland, Scotland and Wales.
It includes some local maps of land cover plus two Appendices. Appendix 1 provides further details on the Corine Land Cover 2012 classification used herein and Appendix 2 provides some further supplementary data tables.
Overall, the UK is nearly 29% pasture land and just over 27% non-irrigated arable land. In terms of land cover, the UK is less than 6% urban. See this report and the associated maps for more detail.

An art exhibition which explores the earliest recorded history of Australia and its neighbouring islands has landed at the John Curtin Gallery in Bentley.
Lisa Reihana: Emissaries hit Australian shores for the first time this year after debuting to up to 450,000 people in Venice last year, and comes to Perth after first showing in Sydney.
The exhibition features works from the earliest points in the region’s recorded history, including cabinets used to store specimens from Captain Cook’s first voyage to Australia, and prints and drawings based on those by artists on the HMS Endeavour.
At the centre of the exhibition is Ms Reihana’s major piece – the 64-minute long film, In Pursuit of Venus [infected].
In Pursuit’s panoramic depiction of the earliest meetings between indigenous peoples and British explorers in the south Pacific reveals the people, cultures, and experiences recorded over four voyages, and the interactions upon meeting.
The feature took Ms Reihana seven years to complete, and involved more than 100 actors and production crew.
“This is the centrepiece of the work,” she said.
“Venus is to do with Captain Cook, as it was the global moment they were recording the travel of Venus – which set longitude and helped fill in the map of the world.
“Infected brings a whole other complexion.”
Ms Reihana said she went to great lengths to include a variety of recorded historical references within the work.
“I found a sea shanty written by one of the crew members, and I had it recorded,” she said.
“I wanted to balance up the idea of performances and sounds – Polynesian dancers, as well as European cultural practices.
“There’s lots of different pieces in it.”
Ms Reihana said Emissaries had been tailored to a Perth audience, and will run until April 29.
Entry is free.
Ms Reihana is also hosting a free floor talk on the creation of In Pursuit with collaborator James Pinker on February 7 from 12.30pm to 1.30pm at the John Curtin Gallery.


Malta's history and geography had an important influence on its cuisine. Having had to import most of its foodstuffs, positioned along important trade routes and having to cater for the resident foreign powers who ruled the islands, opened Maltese food to outside influences from very early on. Foreign dishes and tastes were absorbed, transformed and adapted. Italian (specifically Sicilian), Middle Eastern and Arabic foods exerted a strong influence, but the presence in Malta of the Knights of St John and, more recently, the British brought elements from further afield.
Traditional Maltese food is rustic and based on the seasons. Italian influences are probably the strongest, particularly Sicily and the South. Pasta dishes are really popular, but the Maltese them with a softer texture
Mediterranean ingredients such as fresh and sundried tomatoes, parsley and garlic, wine, olive oil and fresh cheese are the base of most traditional Maltese recipes. Traditional cuisine is recognizable by the cheap cuts of meat and dishes that can be served as two meals, which does not make it any less tasty, quite the opposite. The basis of the Maltese cuisine is what is known as the Cucina Povera - the poor man's kitchen.
Maltese desserts have strong Arabic influences with the use of dates and almonds. Traditionally you finish your meal with fresh fruit and some soft fresh Maltese cheese called ġbejniet. An aged version of this hand-made cheese is eaten as a snack or appetizer in a Maltese platter - both have a sweet slightly nutty taste.
