The Archaeology of Ocmulgee Old Fields, Macon, Georgia Publication Year: 2005 A Dan Josselyn Memorial Publication A 17th-century trading post and Indian town in central Georgia reveal evidence of culture contact and change. Ocmulgee Old Fields near Macon, Georgia, is the site of a Lower Creek village and associated English trading house dating from the late 17th and early 18th centuries. It was excavated in the early 1930s as part of a WPA project directed by A. R. Kelly, which focused primarily on the major Mississippian temple mounds of Macon Plateau. The specific data for the Old Fields was not analyzed until nearly 30 years after the excavation. Part of the significance of this site lies in its secure identification with a known group of people and the linkage of those people with recognizable archaeological remains. The Old Fields site was among the very first for which this kind of identification was possible and stands at the head of a continuing tradition of historic sites archaeology in the Southeast

Circles in a Square Date: 09/15/2001 at 14:00:48 From: Ash Thotambilu Subject: Circles and squares A circle of radius 1 is inside a square whose side has length 2. Show that the area of the largest circle that can be inscribed between the circle and the square is (pi(17 - 12sqrt(2))). Date: 09/15/2001 at 15:03:25 From: Doctor Jubal Subject: Re: Circles and squares Hi Ash, Thanks for writing Dr. Math. The little circle is inscribed in the corner of the square so that it touches the big circle and both sides of the square. Its diameter lies along one of the square's diagonals. Draw in that diagonal of the square, and label the following points: A: the center of the big circle B: where the diagonal intersects both the big and the little circles. The two circles are tangent at this point C: the center of the little circle D: where the diagonal intersects the little circle, opposite B E: the corner of the square that the little circle is inscribed in A,B,C,D,E should lie on the diagonal in that order.

The Clinton administration and Congress are discussing how to best help Colombia win a narco-guerrilla war. The White House has proposed a $1.3 billion aid package over the next two years, which includes funds for judicial and economic reforms. Republicans in Congress want most of the package devoted to military spending. A third voice opposes all military aid for Colombia, arguing that it will only intensify the fighting and lead to more human rights abuses. This opinion is shared by U.S. human rights groups and liberal think tanks. What to do? Colombia is a tough problem, but it is one the United States cannot afford to ignore. This is because both countries share a drug problem. Colombia provides the United States with 80 percent of its cocaine and an increasing portion of its heroin. The United States provides Colombia with consumers who crave illegal drugs and have the means to buy them. Thus, the jungles of Colombia and the streets of America interact every day. The drug trade also has strengthened Colo

Just days after the nation's governors, state commissioners of education, school administrators and education experts proposed draft common core standards for K12 in English and math, major education groups responded. The National Education Association, the National School Boards Association and the Alliance for Excellent Education tout the new standards as promoting 21st- century skills of collaborating, problem solving and critical thinking. "This will be a Good Housekeeping seal of approval," says Bob Wise, president of the Alliance for Excellent Education. "This will say to businesses that want to relocate or parents considering to where they might move, 'This district, this state adheres to the very rigorous standards recognized across the country.'" On March 10, the state-led effort coordinated by the National Governors Association (NGA) Center for Best Practices and the Council of Chief State School Officers (CCSSO) proposed the two drafts: one for math, which is 71 pages long, and one for English-langu

07/22/2004 10:00 AM ET Cooperstown's myth endures By Barry M. Bloom / MLB.com Based on current knowledge, the National Baseball Hall of Fame probably shouldn't be nestled in Cooperstown, N.Y. But the out-of-the-way hamlet, just 70 miles west of Albany, the state's capital, remains the small town at the heart of baseball. Cooperstown was bestowed with that honor because of the mistaken belief that, sometime around the middle of the 19th century, a local resident named Abner Doubleday was the first American to turn the English game of "rounders" into a semblance of what would eventually become baseball. "The Doubleday thing is a total myth. We've got proof in writing. We've got all the papers here," said Ted Spencer, vice president and chief curator of the museum since 1982. The Mills committee, convened in 1905 at the behest of early baseball owner and sporting goods merchandiser Albert G. Spalding, commenced a three-year study of the matter and endorsed Doubleday as baseball's founder. Three decades later, th

From the Farm of Harvey Firestone Aug 20, 2012 It’s a place where Harvey Firestone, Henry Ford and Thomas Edison would hold gentlemen’s camp outs. The 400-acre property in Columbiana, Ohio was deeded to the Firestone family by President Thomas Jefferson and in 1952 was established as the Firestone Test Center. Today, the grounds are used for testing by Firestone Corporation as well as leased to a local farmer for production. Many of the tests are head-to-head comparisons of new Firestone tires vs. the previous design as well as new Firestone tires vs. the competition. With the facilities, Firestone test engineers can simulate four years of wear and use in three months.\ The tests are run 12 months a year on the indoor equipment as well as the five circles with concrete, black top and limestone surfaces. The test circles are the site for wear and durability tests, and the test tractors are run without an operator. The equipment is mounted with the tires for testing, the steering is locked in position, and usin

Posted on Wednesday 27th July 2011 Professor Carole Torgerson from the School of Education, has led a major evaluation of Every Child Counts (ECC), a numeracy programme that was introduced into English primary schools in 2008. The evaluation project, conducted by Researchers from the Universities of Birmingham, Durham and York for the Department for Education, has shown a positive short term effect on children’s numeracy skills and equated the improvement to seven additional weeks’ progress in numeracy skills for each child. Every Child Counts (through the Numbers Count intervention) provides intensive support to the lowest-achieving Year 2 children. Children are taught on a one-to-one basis by a specialist teacher for half an hour a day over the course of a term. The programme is currently being provided to over 20,000 children in about 1700 schools. A randomised controlled trial (RCT) involving 409 children in 44 schools across England assessed the effect of receiving Numbers Count (NC) teaching compared wi

In an effort to solve a problem in rechargeable lithium (Li)-ion batteries that prevents them from quickly accepting or discharging energy, engineering researchers at Rensselaer Polytechnic Institute intentionally engineered defects in a sheet of graphene, resulting in a graphene anode material that can be charged or discharged 10 times faster than conventional anodes used in current li-ion batteries. “Li-ion battery technology is magnificent, but truly hampered by its limited power density and its inability to quickly accept or discharge large amounts of energy. By using our defect-engineered graphene paper in the battery architecture, I think we can help overcome this limitation,” said Nikhail Koratkar, the John A. Clark and Edward T. Crossan Professor of Engineering at Rensselaer. “We believe this discovery is ripe for commercialization, and can make a significant impact on the development of new batteries and electrical systems for electric automobiles and portable electronics applications.” According to

The Field of Motion and the Equation of Continuity The Field of Motion. Among vector fields the field of motion is of special importance. Several of the characteristics of the field of motion can be dealt with without considering the forces which have brought about or which maintain the motion, and these characteristics form the subject of kinematics. The velocity of a particle relative to a given coordinate system is defined as ν = dr/dt, where dr is an element of length in the direction in which the particle moves. In a rectangular coordinate system the velocity has the components The velocity field can be completely described by the Lagrange or by the Euler method. In the Lagrange method the coordinates of all moving particles are represented as functions of time and of a threefold multitude of parameters that together characterize all the moving particles. From this representation the velocity of each particle, and, thus, the velocity field, can be derived at any time. The more convenient method by Euler

Sex and the After Shock June 1, 2010 Sex: it’s such a small word, but has so many meanings, feelings, opinions, beliefs and consequences, both positive and negative, attached to it. Most people, no matter what their age or level of maturity, find it difficult to discuss sex and often shy away from doing so. Parents often reduce a discussion of sex to the “birds and the bees” talk, when in fact it is a wonderful umbrella topic for sexuality, reproductive health, relationships, interpersonal dynamics, intimacy, body image, gender roles, broken hearts, abuse, violence, unwanted sexually transmitted diseases (STDs), pregnancy, addiction and growing up in general. Sex is laden with religious and spiritual beliefs, cultural upbringing, media imaging and peer review. Because sex is a complex human interaction, the effects of becoming sexually active vary depending upon whether the sex was truly consensual, made under pressure, exploitive, honest, protected against STDs and pregnancy, and aligned with one’s internal

"This scientific collaboration between the United States and Australia represents another important step in our quest to gain a better understanding of the human genome," said NHGRI Director Francis S. Collins, M.D., Ph.D. "As we build on the success of the Human Genome Project, it has been increasingly clear that one of the best tools for identifying crucial elements in the human genome is to compare it with the genomes of a wide variety of other animals." Comparing the human genome sequence with those of other organisms, such as the roundworm, mouse or kangaroo, enables scientists to identify regions of similarity and difference that can provide clues about the structure and function of genes vital to human health and development. The type of kangaroo chosen for sequencing is the tammar wallaby (Macropus eugenii), a relatively small member of the kangaroo family found on islands along Australia's southern and western coasts. Researchers are studying the tammar wallaby to gain insights applicable to human re

I have a pseudo random counter that looks like below. Briefly what it does is to generate a "random" number every time the system is clocked. I say "random" and not random because the register values in the counter follows the same pattern every time, if you start from 0. If the feedback to the first register is done correctly throe the three XNOR logical blocks, the next number that appears in the register will not be similar to any other you can generate. Meaning that if you have 12 bits, you get 2e12 different combination's. With one exception, the very last clock is not correct, so it has to be skipped. So what you end up with using a counter like this is 4095 pseudo random numbers reaching from 0 to 4094 in binary. What I want to do is to calculate how many clock cycles it took to reach any of the values that can be in the 12 bit register. This can be done with a lookup table. Or with logical block working like a transform from the scrambled numbers to the binary order [00 0000 0000], [00 0000 0001], [00

||Issue Date: 12 / 2007 Elephant Grass for Biomass Energy Developments in Brazil Elephant Grass or Pennisetum Purpureum at the Hawaii Ecosystems at Risk project. FOREST & KIM STARR(USGS) Click image to enlarge. Sugarcane is gradually being edged out of pole position for biofuel efficiency, as studies by the Agrobiology Centre at the state Brazilian Agricultural Research Corporation (Embrapa) are finding that elephant grass has even greater potential. Its dry biomass, burned in ovens, can generate 25 times as much energy as the amount of fossil fuel used to produce it, while sugarcane converted into ethanol only produces nine times as much. But these two energy balance leaders face different challenges and must travel down different paths before they can compete, for instance, as fuels for electricity generation. Elephant grass (Pennisetum purpureum) has only recently captured the interest of large energy consumers and companies, after decades of scientific research. It is a cane-like species of grass, brought

Fracture patterns and their origin in the Upper Devonian Antrim Shale gas reservoir of the Michigan basin: A review Robert T. Ryder Open-File Report 96-23 PATTERNS OF GAS PRODUCTION AND CHEMISTRY OF ASSOCIATED RESERVOIR WATER The influence of fractures on gas production is demonstrated by a plot of fracture frequency, measured from fracture-detection logs in three wells in Otsego County, against gas production from these wells (Decker, 1992). The plot shows a direct relationship between fracture frequency and gas production. The three wells used in the plot were also used in fracture studies by Decker and others (1992) and Caramanica (1993). Gas production from the three wells, measured over 24 hours, ranged from 243 to 500 thousand cubic feet of gas per day (MCFGPD). Accompanying water production from the wells ranged from 25 to 85 barrels of water per day (BWPD). All the wells are vertical, received similar stimulation treatment, and were tested for their gas yield at similar times in their production histo

She has also served the community as a teacher, principal and school board member. Throughout her career, Congresswoman Wilson has stood up for those without a voice. As a school principal she stood up for her students and their families and fought against an environmentally dangerous composting plant that was built across the street from her school. She won the battle, and the Miami Dade County Commission was forced to close the plant. She also took a stand when Haitian refugees were incarcerated in a local detention center in 1984.

Obscured populations ISO and SCUBA observations of the HDF and other fields have revealed an energetically important population of dust-obscured objects. Interpretation of these results has been the subject of considerable debate, because of ambiguities in source identification and in distinguishing starbursts from AGN. The ISOCAM (6.7 and 15 µm) and SCUBA (850 µm) observations bracket but do not sample the wavelength regime 100 < p < 200 µm near the peak of the far-IR emission, making it difficult to assess reliably the source contribution to the global emissive energy budget of galaxies. Although strong mid-IR emission accompanies vigorous star formation in many nearby galaxies, the unidentified IR emission bands carry most of the energy in the wavelength range sampled by ISOCAM at z ~ 1. The bulk of re- emitted radiation, however, emerges near p, and there is considerable diversity in f (10 µm) / f(100 µm) flux ratios am

The Peace Corps The Peace Corps was founded in 1961 by President Kennedy to challenge our nation to look beyond our borders and to serve our country by serving the people of other nations. Fifty years later, we are reminded of the power of service and how we can best invest in development, public diplomacy and our global community. Peace Corps Response is a program within the Peace Corps that has specialized short-term, high-impact assignments ranging in length from three to twelve months. Volunteers arrive in the field with the language, technical and cross-cultural skills identified by our host country partners. Peace Corps Response grew out of an effort established in 1996 at a White House ceremony by President Clinton. The President announced the establishment of Crisis Corps, a program designed to quickly mobilize Returned Peace Corps Volunteers and provide short-term disaster relief and humanitarian aid to countries in need.

The pioneering British photographer Eadweard Muybridge (1830-1904) will be the subject of a major retrospective at Tate Britain in autumn 2010. Bringing together around 150 works, this exhibition will demonstrate how Muybridge broke new ground in the emerging art form of photography. From his iconic images of animals and humans in motion to depictions of the sublime landscapes and life of the dynamic America of the later nineteenth century, the exhibition will explore the ways in which Muybridge created and honed his remarkable images that continue to resonate powerfully with artists and photographers. Born in Kingston upon Thames in April 1830, Muybridge studied photography in Britain and built his career in America. Perhaps best known for his extensive photographic portrayal of animals and human subjects in motion, he was also a highly successful landscape and survey photographer, documentary artist, inventor, and war correspondent. Muybridges revolutionary techniques produced timeless images that have prof

It's Only Natural: Evaluating Natural Language Dialogs Your decision on whether to use a natural dialog approach instead of a directed dialog in an IVR application will directly affect the cost, effort and maintenance of the system. This article will give you a process that you can use to make the right decision. Natural Dialogs versus Directed Dialogs A natural dialog is one in which the prompts, grammars and dialog flow are modeled and designed to more closely simulate a real conversation between two people. Natural dialogs allow the human to participate in controlling the dialog flow. Directed dialogs on the other hand use a pre-defined set of steps and usually occur in a sequential, linear fashion. Directed dialogs are modeled in a dialog-flow fashion, similar to a call-flow for touch tone IVRs. Natural dialogs, on the other hand, typically utilize a finite state model where dialogs are executed based on the state of one or more variables. There isn't a clear dividing line between directed dialogs and nat

Project Leader: Tiziano Bandiera, PhD The natural cannabis-like substance, anandamide, is produced in injured tissues and activates specialized receptors on pain-sensing terminals, called cannabinoid receptors, which prevent the access of pain- carrying signals to the brain. Working with research groups in the USA and Italy, we identified compounds that selectively stop the degradation of anandamide, caused by the enzyme fatty acid amide hydrolase (FAAH), outside the brain. By doing so these compounds produce profound analgesic effects in animal models of pain. Indeed, even though fact these molecules do not enter the brain and spinal cord, their pain-killing actions are equal or superior to those of centrally active analgesics such as morphine. Because of their remarkable efficacy and favorable safety profile, these compounds have been advanced to preclinical development for post-operative and nociceptive pain.

Of late, almost every author who has studied the subject has come to this conclusion. The case of America alone would almost suffice to prove its truth; for if we exclude the arctic and northern temperate parts, all authors agree that one of the most fundamental divisions in geographical distribution is that between the New and Old Worlds; yet if we travel over the va

The increasing reliance on online courses at California’s community colleges is contributing to the grade gap between Latino and white students, according to a recent study that examined millions of student records. The study, conducted by Raymond Kaupp, director of workforce development in Cabrillo College near Santa Cruz, found that while Latino students lag behind white students in the grades they get in regular courses, the gap is far wider in online courses. Kaupp’s findings cast a shadow over the impact of online courses, which have become a standard feature of campus offerings and are growing in popularity at California’s 112 community colleges. (See this website on “California’s Virtual Campus” for online courses offered at community colleges and CSU and UC campuses.) The performance of Latinos on online courses is especially worrisome. Almost two-thirds of college-bound Latino high school graduates start their college education at a community college. Because many of them work and have families, they

The Future Lies in Wood Pulp There are so many good things to say about nano-crystalline cellulose, it's hard to know where to begin. It's lightweight, it conducts electricity, it's strong as Kevlar, it's not harmful to humans, and it's made cheaply from a resource we've got in spades. And as of July, it's being produced at a Wisconsin factory run by the U.S. Forest Service's Forest Products Laboratory, the third of its kind and the first in the United States. Executives from IBM, Ecolab, and Lockheed Martin attended the opening of the $1.7 million facility in Madison, which is expected to support the burgeoning nanocellulose market and contribute to what the USDA thinks will be a $600 billion industry by 2020. In this video from the local NBC news station, experts predict a "domino effect across all industries," and called the plant a "game-changer." So what is it exactly?

Second-generation Americans—the 20 million adult U.S.-born children of immigrants—are substantially better off than immigrants themselves on key measures of socioeconomic attainment, according to a new Pew Research Center analysis of U.S. Census Bureau data. They have higher incomes; more are college graduates and homeowners; and fewer live in poverty. In all of these measures, their characteristics resemble those of the full U.S. adult population. Hispanics and Asian Americans make up about seven-in-ten of today’s adult immigrants and about half of today’s adult second generation. Pew Research surveys find that the second generations of both groups are much more likely than the immigrants to speak English; to have friends and spouses outside their ethnic or racial group, to say their group gets along well with others, and to think of themselves as a “typical American.” The Pew Research surveys also find that second-generation Hispanics and Asian Americans place more importance than does the general public on

for National Geographic News Cuttlefish have been captured on film exhibiting sophisticated camouflage strategies at night, according to scientists who are using new high-resolution cameras to bring these dramatic changes into focus. They are also using underwater spectrometers to measure color wavelength to determine how other marine creatures perceive these shifts. The findings are helping to crack the code of cephalopods, including cuttlefish, which also employ shape-shifting strategies to conceal themselves as coral or algae. For the last nine breeding seasons, Roger Hanlon, senior scientist at the Marine Biological Laboratory at Woods Hole, Massachusetts, and a National Geographic Society grantee, has closely studied their camouflage strategies. (National Geographic News is owned by the National Geographic Society.)

By Arthur Max, Associated Press AMSTERDAM, Netherlands Only a few years ago, oil from palm trees was viewed as an ideal biofuel: a cheap, renewable alternative to petroleum that would fight global warming. Energy companies began converting generators and production soared. Now, it's increasingly seen as an example of how well-meaning efforts to limit climate-changing carbon emissions may backfire. Marcel Silvius, a climate expert at Wetlands International in the Netherlands, led a team that compared the benefits of palm oil to the ecological harm from destroying virgin Asian rain forests to develop lucrative new plantations. His conclusion: "As a biofuel, it's a failure." Scientists and policymakers from more than 100 countries are meeting in Brussels, starting Monday to report on the impact of global warming, including storms, flooding and the extinction of plants and animals. Then in May, the group intends to issue recommendations on how best to fight it, through new technologies and possible use of alterna

Peanuts are among the most common allergy-causing foods, and they often find their way into things you wouldn't imagine. Take chili, for example: It may be thickened with ground peanuts. Peanuts aren't actually a true nut; they're a legume (in the same family as peas and lentils). But the proteins in peanuts are similar in structure to those in tree nuts. For this reason, people who are allergic to peanuts can also be allergic to tree nuts, such as almonds, Brazil nuts, walnuts, hazelnuts, macadamias, pistachios, pecans, and cashews. What Happens With a Nut or Peanut Allergy? The body's immune system normally fights infection. But, when someone is allergic to tree nuts or peanuts, the immune system overreacts to proteins in these foods. Every time the person eats (or, in some cases, handles or breathes in) a peanut or tree nut, the body thinks the proteins are harmful invaders. The immune system responds by kicking into high gear to fend off the "invader." This causes an allergic reaction, in which chemicals

Radar during World War II Radar during World War II It has been said that radar won the war for the Allies in World War II. While that’s an overstatement, it is true that radar had a huge impact on how World War II was fought on both sides. Radar is, in essence, a very basic way of obtaining information. That very simplicity makes it highly adaptable—during the war scientists and engineers found dozens of ways of using it. During World War I (1914-1918) airplanes played a relatively small role, being used mainly for reconnaissance. But as airplanes increased in size, range, and speed in the 1920s, it became clear that they would become major weapons in future wars. Bombing was the major concern. Airplanes might carry enormously destructive bombs, and there was little to prevent enemy aircraft from reaching a nation’s cities. The words of British Prime Minister Stanley Baldwin, spoken in 1932, were well known: “the bomber will always get through.” The threat of bombing revived interest in a technology that had

- Adaptation of hepatitis C virus to mouse CD81 permits infection of mouse cells in the absence of human entry factors (2010) - Hepatitis C virus (HCV) naturally infects only humans and chimpanzees. The determinants responsible for this narrow species tropism are not well defined. Virus cell entry involves human scavenger receptor class B type I (SR-BI), CD81, claudin-1 and occludin. Among these, at least CD81 and occludin are utilized in a highly species-specific fashion, thus contributing to the narrow host range of HCV. We adapted HCV to mouse CD81 and identified three envelope glycoprotein mutations which together enhance infection of cells with mouse or other rodent receptors approximately 100-fold. These mutations enhanced interaction with human CD81 and increased exposure of the binding site for CD81 on the surface of virus particles. These changes were accompanied by augmented susceptibility of adapted HCV to neutralization by E2-specific antibodies indicative of major conformational changes of virus-

Best of the Web “A History of New York in 50 Objects” If you ask 50 people “What happened?” you will likely get 50 slightly different stories. The facts and the context of the story may be the same, but how one relates to the facts and the context determines one’s own version of the story. So there is something to the notion of there’s my version, there’s your version and there’s the truth. The New York Times enlisted historians and museum curators to find 50 objects that could embody the story of New York. They included a 13,000-year-old mastodon tusk that was discovered in the Bronx in 1891; a boombox like the one Radio Raheem carried everywhere in Spike Lee’s movie “Do the Right Thing”; and a jar of dust from the 9/11 site where two jet planes were flown into the World Trade Center towers by terrorists. Though inanimate, the objects provide a glimpse into the history and culture of New York City. With so many new methods and media for storytelling, “Story(us)” was founded in the belief that shared stories

County Structure & Powers There is a fundamental distinction between a county and a city. Counties lack broad powers of self- government that California cities have (e.g., cities have broad revenue generating authority and counties do not). In addition, legislative control over counties is more complete than it is over cities. Unless restricted by a specific provision of the state Constitution, the Legislature may delegate to the counties any of the functions which belong to the state itself. Conversely, the state may take back to itself and resume the functions which it has delegated to counties (e.g., state funding of trial courts). Types of Counties The California Constitution recognizes two types of counties: general law counties and charter counties. General law counties adhere to state law as to the number and duties of county elected officials. Charter counties, on the other hand, have a limited degree of “home rule” authority that may provide for the election, compensation, terms, removal, and salary o

Destinations in Indonesia The Sade Village, the Sasak of Lombok and their Way of Life The Sasak are the indigenous people of the island of Lombok. Like many ethnic groups in Indonesia, they belong to the Austronesians who migrated from mainland Asia some 5,000 years BC to populate South East Asia all the way to the South Pacific Islands. Today 85% of the Lombok population is Sasak. Although Bali has greatly influenced Lombok, yet unlike in Hindu Bali, most Sasak embrace Islam. A distinct feature of religion here is what is known as Wektu Telu, a syncretic belief of Islam intertwined with elements of Hinduism, Buddhism, and ancient traditional beliefs, unique to Lombok. Many Sasak have, nonetheless, also come to embrace the Wektu Lima, or the mainstream Islamic obligatory five time prayers in a day. There is also a small minority whose faith is called Bodha, a syncretic belief of animism and Buddhism. Nonetheless, despite differences in religious beliefs, the Sasak live in harmony among themselves. The most an

Tree of life (biblical) - See also Tree of life for other cultural interpretations, and Tree of life (disambiguation) for other meanings. The tree of life (Heb. עץ החיים Etz haChayim) in the Book of Genesis is a tree planted by the Abrahamic God in midst of the Garden of Eden (Paradise), whose fruit gives everlasting life, i.e. immortality. Together with the tree of life, God planted the tree of the knowledge of good and evil (Genesis 2:9). According to some scholars, however, these are in fact two names for the same tree. In the biblical story, the serpent, who is regarded as Satan in Christianity but not in Judaism, tempted Eve into eating a fruit from the tree of the knowledge of good and evil. Eve and Adam both ate the fruit, despite God's warning to Adam that "in the day that you eat from it you shall surely die" (Genesis 2:17). As a consequence of their transgression, the land, the Serpent, Adam, and Eve were each cursed by God. To prevent them access to the tree of life, God cast Adam and Eve out of th

Every ten years or so, environmental problems come to the fore and governments use a lot of energy trying to find solutions to problems such as global warming, global cooling, natural resource extraction and over-fishing. We are going through one such phase at the moment. As Catholics, we should of course think of the needs of future generations and we should care for the created universe. Indeed, our own local Bishops conference published a document on the environment in 2002 though it left much to be desired. There are three concepts in Catholic Social Teaching that are often held in constructive tension and that are relevant to environmental issues. The first is the primacy of private property and the autonomy of individuals and families. Secondly, there is the universal destination of goods and the recognition that private property, though very important, is not sacrosanct. Thirdly, there is the notion that government should always behave in such a way that promotes the common good: generally through supp

What LEED Measures LEED is a voluntary certification program that can be applied to any building type and any building lifecycle phase. It promotes a whole-building approach to sustainability by recognizing performance in key areas: Choosing a building’s site and managing that site during construction are important considerations for a project’s sustainability. The Sustainable Sites category discourages development on previously undeveloped land; minimizes a building’s impact on ecosystems and waterways; encourages regionally appropriate landscaping; rewards smart transportation choices; controls stormwater runoff; and reduces erosion, light pollution, heat island effect and construction-related pollution. Buildings are major users of our potable water supply. The goal of the Water Efficiency credit category is to encourage smarter use of water, inside and out. Water reduction is typically achieved through more efficient appliances, fixtures and fittings inside and water- wise landscaping outside. |Energy & At

Over 1 million individuals, in the United States, are affected by kidney stones each year. The pain in your Kidney, abdomen, or flank is some of the worst you can have. Just ask anyone whose ever had a kidney stone. It isn’t surprising the lengths people will go to – to avoid kidney stones. Recently studies have looked at the reason why certain people get kidney stones and others don’t. Genes are only partly to blame. Often kidney stones form when urine becomes too concentrated. This pushes substances together, such as calcium and other materials link together and soon crystallize. The resulting kidney stone begins. Diet, of course, plays a significant role in kidney stone formation. Water intake, Sodium intake, Excessive caffeine or soda. – Just to mention a few. Treatment for kidney stones often depend on the size of the stone and the amount of pain. Often, a recommendation to just let the stone pass is the most prudent. But in some cases, surgery is required. After treatment – often patients forget about t

Combat is an ancient human and even pre-human practice, and is certainly among the oldest of human social endeavors. That's correct, social. The two basic types of combative behavior- affective and pseudo-predatory-have very primary social aims: establishing position within the group hierarchy for the former, and protecting the group (and self) from enemies in the case of the latter. Today, in polite society, affective combative behavior is, of course, frowned upon as being socially dysfunctional, while pseudo-predatory combative behavior is generally not even acknowledged by anyone other than the professionals who deal with it. However, the pseudo-predatory combative behavior of the professional is the only appropriate form of combative behavior for law enforcement and the In spite of combat's negative political correctness, its audience appeal obviously continues unabated from well before the era of gladiatorial combat in the arenas of the Roman Empire.

Swimmer's ear is an infection of the ear canal. Doctors call it external otitis. Symptoms of swimmer's ear include: - Itching of the ear canal - Redness of the skin of the outer ear or ear canal - Drainage from the ear canal (often yellow, green or possibly cheesy) - Pain when touching the ear or moving the jaw while chewing or talking - Decreased hearing from debris that clogs the ear canal Swimmer's ear can be caused by bacteria or fungi. It is called swimmer's ear because it is associated with frequent swimming. Long and frequent exposure to water makes the skin of the ear canal more susceptible to infection. Warm and humid conditions can do the same thing. That's why swimmer's ear is most common in the summer. Sometimes swimmer's ear can be treated by clearing the ear canal of debris and keeping it dry. However, doctors usually prescribe ear drops to promote quicker healing. The most commonly used drops combine medications to fight the infection and calm the inflammation.

Despite most commonly being found in women, breast cancer can also be diagnosed in men. That is why breast cancer is often considered one of the most common types of all diagnosable cancers. Fortunately, if you are diagnosed as having cancer, there are a number of treatment options that may help you become cancer free. However, before that can occur, you need to be diagnosed as having breast cancer. When it comes to being diagnosed with breast cancer, a large amount of focus is placed on the signs and symptoms. While it is important to focus on the symptoms of breast cancer, they are not the only things that you should keep in mind. Although an exact cause of breast cancer has yet to be determined, there are a number of risk factors associated with the cancer.

We easily understand how beating a child may damage the developing brain, but what about the all-too-common psychological abuse of children? Because the abuse was not physical, these children may be told, as adults, that they should just “get over it.” But as developmental neuropsychiatrist Martin H. Teicher reveals, scientists are discovering some startling connections between abuse of all kinds and both permanent debilitating changes in the brain and psychiatric problems ranging from panic attacks to posttraumatic stress disorder. In these surprising physical consequences of psychological trauma, Teicher sees not only a wake-up call for our society but hope for new treatments. We know that the abuse or neglect of children is tragically common in America today. Nor are most of us surprised when studies point to a strong link between the physical, sexual, or psychological maltreatment of children and the development of psychiatric problems. To explain how such problems come about, many mental health professio

After a month-long run on American banks, Franklin Delano Roosevelt proclaimed a Bank Holiday, beginning March 6, 1933, that shut down the banking system. When the banks reopened on March 13, depositors stood in line to return their hoarded cash. This article attributes the success of the Bank Holiday and the remarkable turnaround in the public's confidence to the Emergency Banking Act, passed by Congress on March 9, 1933. Roosevelt used the emergency currency provisions of the Act to encourage the Federal Reserve to create de facto 100 percent deposit insurance in the reopened banks. The contemporary press confirms that the public recognized the implicit guarantee and, as a result, believed that the reopened banks would be safe, as the President explained in his first Fireside Chat on March 12, 1933. Americans responded by returning more than half of their hoarded cash to the banks within two weeks and by bidding up stock prices by the largest ever one-day percentage price increase on March 15--the first tra

Wood plastic composite material In this study some of the important properties of experimentally manufactured wood– plastic composites (WPC) were determined. Specimen having 60% and 80% particle and fibre of radiata pine (Pinus radiata ) were mixed with polypropylene (plastic) and four different additives, namely Struktol TR 016 which is coupling agent, CIBA antimicrobial agent (IRGAGUARD F3510) as fungicide, CIBA UV filter coating (TINUVIN 123S), CIBA blue pigment (IRGALITE), and their combinations. Based on the initial finding of this work static bending properties of the samples enhanced as above chemicals were added into both particle and fibre-based specimens. Thickness swelling of the samples were also improved with having additives in the panels. Micrographs taken on scanning electron microscope (SEM) revealed that coupling agent and pigment resulted in more homogeneous mixture of wood and plastic together.

I have the same problem when I am listening to something challenging(i.e. not the undergraduate math club). For me, one of the most helpful things I can do is that once a definition is given, I construct both examples and constructions that almost fit the definition but do not fit one of the criteria. I then check how these work(or fail) with the theorems presented and the claims made. If you find a simple example and are having trouble following, the person lecturing will probably be happy explaining how the concepts presented relate to your example. Another idea that helps is for me to read all the material beforehand, no matter how confused I am. Then I can pay attention to how it is structured in class. Even if I do not understand the lecture, contrasting the structures of the reading and of the lecture can give me deeper understanding of the material. In addition, since I (like to think I ) understand how to structure a lecture, it gives me something I can understand to pay attention to. Lastly, I think

December 28, 2010 > Empowering students to save lives Empowering students to save lives Story and Photos by Miriam G. Mazliach An excited group of 160 students piled into the multi-use room at Walters Junior High in Fremont on the morning of December 16. Throughout the day, the school's 7th graders would take part in CPR training. What they were about to learn had the potential to save many lives. Jamie Hintzke, Community Relations Coordinator for Alameda County Health Care Services Agency, explained that in 2007 Alameda County tested a pilot program with both 7th and 10th grade students. The results showed that twice as many 7th graders participated or did outreach to community members than 10th grade students; the 7th graders trained an average of five family members and friends. As a result, it was determined that the CPR7 program would focus on 7th graders.

Hazelwood Fogging Mosquitos to Minimize West Nile Virus Risk With indications that the recent West Nile virus outbreak is the largest seen in the U.S., Hazelwood officials want residents to know that the city has taken proactive measures to control the mosquito population and the likelihood of a West Nile virus epidemic breaking out in the community is minimal. “We’ve been fogging for mosquitoes twice a week covering the whole city since the month of May,” said Paul Williams, Hazelwood Street Maintenance Department supervisor. “The extreme heat and drought conditions we had this summer cut down on the number of mosquitoes in our area because there was very little standing water where their larvae could hatch. But the milder temperatures may cause the mosquito population to grow which is why we’re prepared to continue our mosquito fogging efforts until October.” In addition to fogging, the City of Hazelwood has been using “dunks” which are products that kill mosquito larvae.

A big brother allows the baby sitter to misunderstand his little sister in this Scottish import. Small Jessie is just learning words, and when she says “please” it sounds just like PEAS. Mum and Dad are off to a ceilidh (Dad's in his kilt and Mum's in her dancing boots), and they tell Rachel, the baby sitter, to give Jessie anything she asks for, as she is just getting over a cold. So when she asks for “Orange juice peas” Rachel gamely finds some leftover cooked peas in the fridge and drops a few in the juice. Jessie is not pleased, and she asks for a “Boon peas!” Ben translates “spoon” but not the other, so Jessie gets a spoon with peas, which she uses to get the peas out of her juice. Alas, though, now the orange juice tastes of peas. “Yack!” says Jessie. This continues. While Ben tries to hold in his giggles, Jessie grows ever more frustrated, and Rachel gets increasingly mystified. There are peas all over the place. Finally, Ben explains that Jessie means “please,” not that she wants peas with everything.

The Earth in its orbit at the solstices and equinoxes. Click on image for full size The Seasonal Merry-Go-Round The tilt of Earth's rotational axis and the Earth's orbit work together to create the seasons. As the Earth travels around the Sun, it remains tipped in the same direction, towards the star Polaris. This means that sometimes the northern half of the Earth is pointing towards the Sun (summer ), and sometimes it is pointing away (winter ). These points in the Earth's orbit are called solstices Notice that when the northern hemisphere is tilted towards the Sun, the southern hemisphere is tilted away. This explains why the hemispheres have opposite seasons. Halfway in between the solstices, the Earth is neither tilted directly towards nor directly away from the Sun. At these times, called the equinoxes, both hemispheres receive roughly equal amounts of sunlight. Equinoxes mark the seasons of autumn and spring and are a transition between the two more extreme seasons, summer and winter. Shop Windows to t

Wildlife Costa Rica – 9 Truths About Raccoons Raccoons are medium-sized mammals that learned to live close to humans. And have a reputation of nocturne thieves. In real life they are just animals trying to adjust to the changes men are producing. They are found throughout different landscapes of Costa Rica such as rainforests, cloud forests and beaches. Here are some things that will make you understand them a little bit better: 1. The dense under-fur is almost 90% of the raccoon’s grayish coat. Two of its most distinctive features are its black paws and its facial mask. 2. Females often share a common area, while unrelated males live together in groups of up to four animals to maintain their positions against foreign males during the mating season and other potential invaders. 3. Although captive raccoons have been known to live over 20 years, their average life expectancy in the wild is only 1.8 to 3.1 years. 4. After a gestation period of about 65 days, two to five young are born in spring. The kits are ra

A video conference is a live communications connection between people in separate locations involving audio, video, and often data transmission (text, graphics, PowerPoint presentations, sharing Word or Excel documents, etc.). At its simplest, video conferencing provides transmission of static images and text between just two locations. At its most sophisticated, it provides transmission of full-motion video images and high- quality audio between multiple locations. Video conferencing systems typically consist of cameras, microphones, a codec (coder-decoder, which handles the video, audio, and data signals), network access equipment, a network, and other specialized equipment. It is important to distinguish between conferences with only two remote sites and those conferences where a larger number of sites are involved. A point-to-point video conference is only between two sites. A multi-point video conference includes more than two sites, and requires some method for each site to receive the communications fro

There is nothing more fascinating than yesterday's vision of tomorrow — especially when it comes to city design. Here are some of the most incredible futuristic cities imagined by great European designers of the twentieth century and before. We hope that they came to fruition in some alternate timeline. Le Corbusier: Contemporary City For Three Million Inhabitants, 1922 This was the world-famous architect's first big urban project, exhibited at the 1922 Autumn Salon in Paris. The city is a series of concentric belts. In the center was the administrative and business section (24 60-floor towers).

Living > Health Banning tobacco product displays Out of sight out of mind. When it comes to smoking, does it work? Research says it does. A recent study found that keeping tobacco products hidden and out of sight makes it less likely underage youth will purchase them. Cigarettes and tobacco products have been banned from television and radio ads since 1971. Still, you can hardly go to a gas station or convenient store without being bombarded by tobacco ads - cigarettes, cigarellos, smokeless tobacco. In 2011, 14% of Lorain County youth said they smoked sometime in the past 30 days and of those, 60% said they tried to quit, according to the 2011 Community Health Assessment. What might help them quit? How about a little less temptation? In fact, removing tobacco products and displays out of sight can make a huge difference. A recent study found that 85% of adolescents were likely to purchase tobacco products when they were openly displayed. But when the products were hidden away, only 32% purchased them. The st

The human body has twelve pairs of ribs; ten pairs attach to the spine and wrap around to attach to the sternum in the front of the chest, and the two lower pairs only attach to the spine in the back. The ribs serve to protect the internal organs, lungs, heart, liver, kidneys, spleen, from injury. The bones have a lot of nerve endings so when damage occurs, pain is significant. A patient with an isolated rib fracture or a minor costochondral separation usually has a history of falling on the side of the chest, being struck by a blunt object, coughing violently or leaning over a rigid edge. The initial chest pain may subside, but over the next few hours or days pain increases with movement, interfering with sleep and activity and becoming severe with coughing or deep inspiration. The patient is often worried about having a broken rib, and may have a sensation of bony crepitus or abnormal rib movement. Breath sounds bilaterally should be normal unless there is substantial splinting or a pneumothorax or hemothor

Ever had an urge to once in a Blue Moon buy me an Icom-706? Well, lands sake & glory be, your time opportunity has arrived! On New Years Eve we will be treated to a Blue Moon. The current definition of a Blue Moon is a second full moon in a calendar month. Blue Moons occur every two and a half to three years, the next one being on August 21, 2012. New Years Eve Blue Moons are more rare, the last being in 1971. Where the term “Blue Moon” originated no one knows, but it dates to the days of Shakespeare. Back then it had little to do with the calendar cycle, but with an actual visibly blue moon appearance, which of course signaled global calamities in the near future. Sort of a Middle Ages version of Y2K, the 2012 Mayan calendar end of the world & Global Warming. So enjoy the moon and thank you in advance for my new radio.

Diversity Keeps Grasslands Resilient to Drought Climate Change For much of the year drought has been plaguing American grasslands. But a recent study found that grasses do not appear to be losing the turf war against climate when it comes to surviving with little precipitation. The Kansas State University-led study looked at the drought tolerance of 426 species of grass from around the world. The goal was to better understand how grasslands in different parts of the world may respond to the changes in frequency and severity of drought in the future. Grasslands have several important ecological functions, according to Joseph Craine, research assistant professor of biology and the study's lead author. Grasslands convert and store carbon dioxide, are a food source for grazing animals like cattle and bison, and help cool the surrounding atmosphere. "The idea is that if you maintain a diverse grassland, you'll have a large number of drought-tolerant species ready to take over critical functions if there is a chang

AFRICA: One step nearer to cure for river blindness NAIROBI, 12 March 2002 (IRIN) - It is bacteria inside parasitic worms, and not the worms themselves, that cause river blindness, according to the latest research published by British-based Nature magazine. Onchocerciasis, more commonly known as river blindness, earned its name because of its most extreme manifestation. Its variety of symptoms range from serious visual impairment, including blindness; rashes, lesions, intense itching and de-pigmentation of the skin; lymphadenitis, which results in hanging groins and elephantiasis of the genitals; and general debilitation. The World Health Organisation reports that of the 36 countries where the disease is endemic, 30 are in sub- Saharan Africa (plus Yemen) and six in South America. An estimated 17 to 18 million people suffer from it. The minute offspring of parasitic worms - carried by black flies endemic in fertile riverside areas - called microfilaria were believed to cause the disease, Nature reported, with

The Regionalist art movement reflects a distinct period in U.S. history, including the efforts by artists to define a uniquely American style. This concentration on a specific geography and culture would emanate, in its purest form, from the American Midwest of Thomas Hart Benton, John Steuart Curry, and Grant Wood. Regionalism and the Art of the WPA includes works by these and other artists who drew their inspiration from their immediate surroundings, both rural and urban. In a collaborative endeavor between GVSU and the Muskegon Museum of Art, the Art Gallery will host this exhibition of more than 40 works drawn from the MMA’s collection. The collaboration is in conjunction with the MMA’s hosting of 1934: A New Deal for Artists, organized and circulated by the Smithsonian American Art Museum, Washington, D.C., and scheduled in Muskegon for February 16 through May 6, 2012.

It is the largest power plant in the North Caucasus and the highest arch dam in Russia. The Sulak river, the dam of the Miatlinskaya hydro-electric power plant and its reservoir. The Chirkeiskaya hydro-electric power plant has been built in the gorge 200m deep (the width of the gorge in its lower part is 15m, in the upper one – 300m). The conditions of the construction were rather hard due to the uneven relief. The construction works were started in 1966. During the construction of the power plant, for the first time in the USSR, there was widely applied a blasting by presplitting method. Grade 8 earthquake in 1970 became a serious interruption of the building work and it was suspended nearly for a half of a year. Thanks to a high scale of the building mechanization there was achieved the highest efficiency of that time – 12 m3 per 1. The Chirkeiskaya hydro-el

The Millennium Development Goal on water has been met. This is a major global achievement and we should all feel pride in the part that our governments have played to get us to this milestone. That over 2 billion people have gained access to clean water to drink since 1990 shows that aid is working. This essential service is transforming lives. Nadia from Rwanda is just 16; she sums it up well when she says, "before this pump was working we had to get our water from the swamp, it was far away and we would get tired going there. I had to collect water when I was pregnant, which was difficult. We would get sick a lot, we would often get worms. Before all the little children would always fall sick, and I was worried that my baby would also have fallen sick. The clean water has made a big difference. The future is brighter for me and my son". While this and countless other stories provide meaning to this success, there is no time for complacency. We cannot forget that 783 million people are still without access t

If you wear headphones or watch TV while you exercise, you could be missing out on one of the most valuable benefits of working out: the opportunity to boost your brain health. That’s also true if you stick to the same fitness routine until you can perform it on New scientific evidence shows that physical fitness is the key to staying mentally sharp as you age—but it’s crucial to pay attention to what your body is doing, says Michael Gonzalez-Wallace, author of Super Body, Super Brain and and body fitness expert. “There’s lots of research showing that at any age, physical movement boosts brain health and memory, but to get the best cognitive results, you need to be mentally focused and engaged during your workout,” reports Gonzales- Wallace, who recommends exercises that use several muscles at once, requiring precision and coordination. “Traditional exercises, such as biceps curls, are boring because you only use a very limited area of the brain, while more complex movements, such as simultaneously raising you

The arrival of the Prophet Joseph Smith in Kirtland, Ohio, marked the beginning of a period of rapid growth in the membership of the Church. By early June 1831, the Church had grown to about two thousand members. Among those who joined the Church at this time were Sidney Rigdon’s mother and oldest brother; Luke S. Johnson, one of the first missionaries in the Church; and Ezra Booth, who joined the Church after witnessing a miracle. Civic leaders, ministers, newspaper editors, and parishioners joined together in an effort to stop the conversion of their neighbors to the new religion. The Prophet recorded, “Many false reports, lies, and foolish stories, were published in the newspapers, and circulated in every direction, to prevent people from investigating the work, or embracing the faith” (History of the Church, 1:158). During these trying times of slander and abuse, the Lord blessed the Saints with revelations of comfort, peace, and assurance. One of these revelations was section 45, of which the Prophet wro

Finished wood products such as cabinets, floors, or furniture, plywood, particle board, fiberboard, or even paper do not present an obvious environmental hazard. Wood is plentiful at our homes and workplaces, provides us with warmth and stability, and can be highly useful in several industries. However, wood manufacturers must embrace extreme methods to make wood product manufacturing less harmful for their employees and prevent accidents. In October of 2005, a wood products plant exploded in Schofield, WI killing one worker. According to OSHA statistics in 2009, 21 fatalities occurred in the Wood Industry alone. OSHA also reports that “since 1980, more than 130 workers have been killed and more than 780 injured in combustible dust explosions.” Using robots in the wood industry allows wood manufacturers to remove their employees from these dangerous environments and utilize them more effectively, while at the same time trim production costs. Wood manufacturing hazards include dust inhalation during sanding an

The Fossil Record Verifies Creation: Stasis In The Fossil Record Paleontologists conducting research in ancient strata encounter very important fossils that are millions of years old, yet the duplicates of living spiders, flies, frogs, turtles and fish. According to the theory of evolution, these life forms should have exhibited changes over the course of millions of years. They lived in the most ancient periods in the most complex forms, and have come down unchanged to the present day. In other words, they never evolved. There is a stasis or stability in the fossil record, which—according to evolutionists—should not be there at all. Darwin foresaw that life forms that had remained the same for untold millions of years would represent a major difficulty for his theory, and he frequently referred to this. These special species were even given the name of "living fossils" by Darwin himself! The evolutionist paleontologist Peter Douglas Ward emphasizes this problem of Darwin's: Still, Darwin's central tenet was

04.12.2012Migration as a Topic in German MuseumsFrom the Periphery to the Center With a surfeit of history on their hands, many German museums are only now discovering migration as a theme. It's a step in the right direction, says Austrian historian Regina Wonisch, but isn't enough. An interview by Klaudia Prevezanos Why does the issue of "migration" belong in a museum? Regina Wonisch: Because immigrants are a very important part of our society. And when a museum fully understands itself as an institution that addresses societal questions, then migration is a very important component of our history – and therefore of the museum's content, as well. As a theme, has migration been traditionally handled differently in Germany than in other countries? Wonisch: In Germany, France and the Anglo- American countries it was approached very differently. In Germany, the topic surfaced via a wide range of organizations dealing with various aspects of immigration. These organizations wanted to bring their own particular his

Supermoon Saturday Pics Submit your supermoon photos! The moon was about as close as possible to Earth, making it appear bigger and brighter than the average full moon Saturday evening, May 5, 2012. The so-called “supermoon” happens when the moon turns full and it is at its closest approach to earth at 221,802 miles away. The combination of the two effects results in a supermoon. NASA says the supermoon May 5 would appear up to 16 percent larger and 30 percent brighter than a usual full moon. Unusually high and low tides are expected in the days surrounding the supermoon. The bright moonlight might make it more difficult to see the Eta Aquarid meteor shower, which is also peaking at the same time. NASA still predicted up to 60 of the brightest meteors will still be visible each hour Saturday night into early Sunday. The Eta Aquarid meteor shower happens when the Earth passes through a stream of debris left behind by the famed Halley’s comet, and will be visible until May 28.Submit Your Photo

|Is BPA to blame for a lack of friends?| In a new study, researchers at the University of Virginia and University of Missouri found that mice exposed to BPA weren’t as social as other mice. The scientists injected a dose of BPA into maternal mouse plasma and evaluated their offspring’s behavior. The dose reflected the concentrations that can be found in the blood of most Americans. Starting with the first generation of offspring – and lasting the next four generations of mice – the BPA- exposed mice weren’t interacting as much with their peers, didn’t want to spend as much time with adult males when they were juvenile males. Since BPA is an endocrine-disrupting chemical, these results are to be expected, according to the researchers. The endocrine system regulates chemicals such as oxytocin, which helps us trust others. If that system is disrupted, social behavior may be affected. More research is needed to see if human exposure to BPA produces similar outcomes, of course. Source: Fast Company Air purifiers to

What a Positive Test Result Means A positive test result means your body is leaking fetal fibronectin, a sign that your body may be getting ready to deliver. There is an increased chance that your baby is going to arrive early — but not everyone with a positive test result delivers early. The test can be repeated as often as every two weeks to monitor your ongoing risk. Developing a plan of action Knowing this information will help you and your doctor prepare for a possible preterm birth, and take appropriate steps to help manage your pregnancy. Depending on what week of pregnancy you are in, some recommendations your doctor may suggest include: - Limiting activities - Reducing stress - Bed rest - Finding and treating any undiagnosed infection(s) - Watching for cervical changes that would signal onset of labor - Consulting with a high-risk pregnancy specialist - Tocolytic drugs, which are used to alleviate preterm contractions - Corticosteroids, which may aid in your baby's lung development - Monitoring for o

Source: Economic and Political Weekly 7 October 2012 | EN India needs to improve implementation of its Biodiversity Act. Ten years after introducing a Biodiversity Act, India is yet to put it to serious use although several large "development" projects have invited controversy for their likely impact on biodiversity, say Shalini Bhutani and Kanchi Kohli. A National Biodiversity Authority (NBA) was created in 2003, but the government is not bound by its recommendations. The Act was meant to "provide for the conservation of biological diversity," in line with the primary objective of the Convention of Biodiversity (CBD). But, given the reality in which it operates, the question is whether the Act will come anywhere near effecting biodiversity justice. The central government is required by the CBD and the Act to develop national strategies, plans and programmes for conservation and sustainable use of biological diversity. Between 2000 and 2003, a civil society group was commissioned to help prepare India’s Natio

One of the more surprising aspects of the early missions of the NX class Enterprise during the 2150s was the number of hostile alien species which the ship encountered. One of the more mysterious of these incidents came in 2151, during the ship's first year of exploration. Enterprise was deploying Subspace Amplifiers to expand Earth's communications network when an alien vessel approached. The ship refused all attempts at communication, simply observing Enterprise for a short time before departing. Over the next few days the vessel returned several times, but on subsequent visits it scanned Enterprise and then launched a series of unprovoked attacks on the ship. The alien vessel was fitted with a defensive energy screen which Enterprise's torpedoes had little impact upon. The initial haste to get Enterprise out of dock in time to return the Klingon courier Klaang to his home world had meant that there was no time to install the ship's most powerful weapons - three five hundred Gigajoule phase cannon.

The January 2008 issue of Scientific American includes an interesting article by Michael Shermer, Evonomics: Evolution and economics are both examples of a larger mysterious phenomenon. In it Shermer writes, As with living organisms and ecosystems, the economy looks designed — so just as humans naturally deduce the existence of a top-down intelligent designer, humans also (understandably) infer that a top-down government designer is needed in nearly every aspect of the economy. But just as living organisms are shaped from the bottom up by natural selection, the economy is molded from the bottom up by the invisible hand.SKUs are Stock Keeping Units, a measure of the number of types of retail products available. The correspondence between evolution and economics is not perfect, because some top-down institutional rules and laws are needed to provide a structure within which free and fair trade can occur. But too much top- down interference into the marketplace makes trade neither free nor fair. When such attempt

In Cuba, computerized information technology is coming to the rescue of physicians and medical workers. Project InfoMed is the embodiment of this development. Cuba's long-term involvement with health care was bolstered in the early `70s when President Fidel Castro proclaimed his objective that "Cuba will become a world medical power." To a considerable degree this has come to pass (with fifty-seven thousand physicians, Cuba has one doctor for each 192 inhabitants.) Based on a high level of general and specialized education Cuba has invested heavily in medical technology--biotechnology, pharmaceuticals, and medical instrumentation, as examples.

Christmas became a national holiday in 1870. In 1889, the first indoor decorated Christmas tree was placed in the White House, and in 1895, electric lights were added. In 1923, the first National Christmas Tree Lighting Ceremony was held. In 1953, the first White House Christmas card was created by President Dwight Eisenhower who was also an artist/painter. President Kennedy’s 1963 Christmas card was the first to include an explicitly Christian aspect: the nativity. In 1982, Ronald Reagan said, “My fellow Americans, the Christmas and Hanukkah decorations are up around the country, and in a moment we’ll be lighting the National Christmas Tree here in the Nation’s Capital… Some celebrate the day as marking the birth of a great and good man, a wise teacher and prophet, and they do so sincerely. But for many of us, it’s also a holy day, the birthday of the Prince of Peace, a day when ‘God so loved the world, that He sent us His only begotten son to assure forgiveness of our sins.’” (John 3:16) In 2001, the first

At the present day it might perhaps be vain to look in civilised Europe for customs of this sort observed for the explicit purpose of promoting the growth of vegetation. But ruder races in other parts of the world have consciously employed the intercourse of the sexes as a means to ensure the fruitfulness of the earth; and some rites which are still, or were till lately, kept up in Europe can be reasonably explained only as stunted relics of a similar practice. The following facts will make this plain. For four days before they committed the seed to the earth the Pipiles of Central America kept apart from their wives in order that on the night before planting they might indulge their passions to the fullest extent; certain persons are even said to have been appointed to perform the sexual act at the very moment when the first seeds were deposited in the ground.

Though the exact details of his life and expeditions are the subject of debate, John Cabot (or Giovanni Caboto, as he was known in Italian) may have developed the idea of sailing westward to reach the riches of Asia while working for a Venetian merchant. By the late 1490s, he was living in England, and gained a commission from King Henry VII to make an expedition across the northern Atlantic. He sailed from Bristol in May 1497 and made landfall in late June. The exact site of Cabot's landing has not been definitively established; it may have been located in Newfoundland, Cape Breton Island or southern Labrador. After returning to England to report his success, Cabot departed on a second expedition in mid-1498, but is thought to have perished in a shipwreck en route. John Cabot's Early Life Giovanni Caboto was born circa 1450 in Genoa, and moved to Venice around 1461; he became a Venetian citizen in 1476.

Evidence is growing that trauma-focused cognitive-behavioral therapy (TF-CBT) is an effective treatment for sexually abused children, including those who have experienced multiple other traumatic events. This article reviews the research that has examined treatments for sexually abused children and suggests future research priorities in this regard. Most of the studies that have evaluated TF-CBT have been well designed. This treatment model represents a synthesis of trauma-sensitive interventions and well-established CBT principles (Cohen et al., 2001; Deblinger and Heflin, 1996). Trauma-focused cognitive- behavioral therapy was jointly developed by two groups of researchers who have recently worked together to conduct multisite, treatment-outcome studies for sexually abused and otherwise traumatized children. The therapy was developed to resolve posttraumatic stress disorder, and depressive and anxiety symptoms, as well as to address underlying distortions about self-blame, safety, the trustworthiness of othe

Nutrient to Know: Vitamin B12 by Dana Angelo White in Nutrients to Know, June 5, 2012 - Comments (1,103) There are a lot of misconceptions about this vitamin. Get the facts about B-12. What is it? Less commonly known as “cobalamin” this water- soluble vitamin is almost always found in multi-vitamins and B-complex supplements. Unlike most other water-soluble vitaminss, B-12 requires stomach acid for absorption. It’s also stored within the body for many years, unlike others like riboflavin and thiamin that are quickly passed in the urine. Why is it good for you? Your body needs B-12 to help form DNA, to build your nervous system and keep red blood cells healthy. Since the body likes to store B-12, large amounts of supplements are often not necessary – there’s just one catch. B-12 is mostly found in animal products, so folks that follow a long-term vegan diet might need to consider a daily supplement. Since you need stomach acid for absorption, your ability to break it down decreases with age. Folks who take a lo

Design aspects specified by the industrial designer may include the overall shape of the object, the location of details with respect to one another, colors, texture, sounds, and aspects concerning the use of the product ergonomics. Additionally the industrial designer may specify aspects concerning the production process, choice of materials and the way the product is presented to the consumer at the point of sale. The use of industrial designers in a product development process may lead to added values by improved usability, lowered production costs and more appealing products. Product Design is focused on products only, while industrial design has a broader focus on concepts, products and processes.

Chicken feathers, as unlikely as it seems, have turned out to be a wonderfully useful material. Among other things, researchers have found they make for great circuit boards and cheap, efficient storage tanks for hydrogen. Now it turns out they could also be used to create biodegradable, petroleum-free plastics. Researchers at the University of Nebraska-Lincoln say that the protein keratin in chicken feathers, which is strong and durable, as well as the fact that so many of them end up as unused waste, is what makes them such an appealing material. When making the plastic, the scientists heat-treated the feathers to clean them and then pulverized them into a fine powder.
