Two possible pyramid complexes might have been found in Egypt, according to a Google Earth satellite imagery survey.
Located about 90 miles apart, the sites contain unusual grouping of mounds with intriguing features and orientations, said satellite archaeology researcher Angela Micol of Maiden, N.C.
One site in Upper Egypt, just 12 miles from the city of Abu Sidhum along the Nile, features four mounds each with a larger, triangular-shaped plateau.
The two larger mounds at this site are approximately 250 feet in width, with two smaller mounds approximately 100 feet in width.

The site complex is arranged in a very clear formation with the large mound extending a width of approximately 620 feet -- almost three times the size of the Great Pyramid.
"Upon closer examination of the formation, this mound appears to have a very flat top and a curiously symmetrical triangular shape that has been heavily eroded with time," Micol wrote in her website Google Earth Anomalies.
Intriguingly, when zooming in on the top of the triangular formation, two circular, 20-foot-wide features appear almost in the very center of the triangle.

Some 90 miles north near the Fayoum oasis, the second possible pyramid complex contains a four-sided, truncated mound that is approximately 150 feet wide.

"It has a distinct square center which is very unusual for a mound of this size and it almost seems pyramidal when seen from above," Micol wrote.
Located just 1.5 miles south east of the ancient town of Dimai, the site also contains three smaller mounds in a very clear formation, "similar to the diagonal alignment of the Giza Plateau pyramids," Micol stated in a press release.
"The color of the mounds is dark and similar to the material composition of Dimai's walls which are made of mudbrick and stone," the researcher wrote.
HOWSTUFFWORKS: Building the Pyramids
Founded in the third century B.C. under the Ptolemaic king Ptolemy II Philadelphus (309 B.C.–246 B.C.), Dimai was built on top of an earlier neolithic settlement.
Also known as Dimeh al-Siba, Dimeh of the Lions, the town is surrounded by a mudbrick wall that stretches up to 32 feet high and 16 feet thick, and features at its center a ruined stone temple dedicated to the crocodile god Soknopaios.
Indeed, the town's Greek name, Soknopaiou Nesos, means "Island of Soknopaios."

Well known to scholars for the amount of papyri and other inscribed material found among its ruins, Dimai reached its peak during the first and second century A.D. thanks to a major trade route. It was abandoned during the mid-third century A.D.
According to Micol, both sites have been verified as undiscovered by Egyptologist and pyramid expert Nabil Selim, whose findings include the pyramid called Sinki at Abydos and the Dry Moat surrounding the Step pyramid complex at Saqqara.
Selim found that the smaller 100-foot mounds at the site near Abu Sidhum are a similar size as the 13th Dynasty Egyptian pyramids, if a square base can be discovered.

"The images speak for themselves. It's very obvious what the sites may contain but field research is needed to verify they are, in fact, pyramids," Micol said.
The researcher has previously located several possible archaeological sites with Google Earth, including a potential underwater city off the coast of the Yucatan peninsula.
She believes the use of infrared imagery will allow scientists to see the extent of the complexes in greater detail.
The sites have been sent to Egyptologists and researchers for further investigation and "ground truthing," she said.

Cipla launches four in one drug for HIV patients

Cipla launches four in one drug for HIV patients

MUMBAI: India's second largest drug company Cipla has launched Qvir, a combination of four HIV drugs in one single strip that would be used for a single day's treatment. The four drug kit contains Tenofovir and Emtricitabine and Atazanavir and Ritonavir. These drugs will be used for both first and second line treatment of HIV AIDS.

Cipla said by the end of 2010 close to 34 million people were living with HIV and that same year saw 2.7 million patients getting infected by the disease. "Every year about 5-10% of patients fail their first line treatment due to various reasons such as missing doses and the virus developing resistance", said Cipla.

The company said since the tablets are in one strip, there won't be a possibility of patients missing their dosage.

"While we are committed to making drugs affordable and accessible, we also endeavour to have more options for HIV infected patients which are potent, effective, patient-friendly and easy to take", said Y.K.Hamied, Chairman and Managing Director, Cipla.

lue Sugars claims first cellulosic RIN, extends Petrobras deal


Blue Sugars Corp., formerly KL Energy Corp., can lay claim to a first in the world of cellulosic ethanol technology developers. “It was surprising to us when EPA confirmed [we got] the first RIN [renewable identification number] credit for cellulosic ethanol in the U.S.,” CEO Peter Gross said. The ethanol was produced at the company’s subsidiary demo plant, Western Biomass Energy LLC, in 2011 as part of Blue Sugars’ development agreement with Petrobras SA. The cellulosic ethanol was shipped to Brazil for testing and used during the Rio+20 Conference. Petrobras used the second-generation ethanol to fuel a dedicated minivan fleet servicing the United Nations-sponsored international meeting on sustainable development in June.
The Rapid City, S.D.-based company revamped its cellulosic ethanol demonstration plant to adapt its process technology for sugarcane bagasse after signing the initial development agreement with Petrobras in 2010. "Producing ethanol from waste is an achievement. It means more energy with the same acreage,” said Petrobras Biocombustível President Miguel Rossetto in a statement announcing the ethanol’s use at Rio+20. “Applying this technology of second-generation ethanol, Petrobras has already produced 80,000 liters of ethanol in a second-generation demonstration plant located in the United States. Research has been conducted by the Research Center of Petrobras (Cenpes) since 2004, in partnership with scientific institutions and technology companies nationally and internationally, achieving yields of 300 liters (80 gallons) of ethanol per ton of dry bagasse.”
With the goals of the original development agreement met, Blue Sugars signed a technology and patent license agreement with Petrobras. The company has begun engineering work on Petrobras’ first commercial plant, which is to be completed in 2013.
Last week, Blue Sugars announced it has extended its development agreement with Petrobras to do further work on process optimization. Part of the product produced this year will stay in the U.S., Gross said.  “We may have the first cellulosic ethanol actually produced and sold in the U.S.”
The name change, from KL Energy Corp. to Blue Sugars Corp., took place June 27 to reflect the changes in the past two years and a new business focus. “Our core product is sugar,” Gross said. “Those sugars can be converted to ethanol, plus there are companies converting sugars to all kinds of biochemicals. That is a market as big and interesting to us as ethanol.”
After two years of working with bagasse, the company is also poised to return to its earlier work with woody feedstocks. In February, Blue Sugars started a joint development program with Finland energy company St1 Group Oy and its biofuels division St1 Biofuels Oy to convert pine wood residues into fuel-grade ethanol. Following a dispersed biofuels production model, St1 has seven ethanol plants in Finland using its trademarked Etanolix process to convert food industry waste and side streams into ethanol, using waste streams from food processing industries such as potato, bakery, dairy and brewing.
 

Coffee May Help Protect against Skin Cancer

Coffee May Help Protect against Skin Cancer

At least three cups of caffeinated coffee a day appear to protect against basal cell carcinoma, the most common form of skin cancer, but more studies are necessary to confirm the association

Image:
Protection against skin cancer can be added to the list of health benefits that come with drinking coffee, a new study says.
Women who drank more than three cups of coffee daily were 21 percent less likely to develop basal cell carcinoma (BCC), compared with women who drank less than one cup of caffeinated coffee per month, the study showed. For men, this risk reduction was 10 percent.
"Most likely, the protective effect is due to caffeine," said lead author Jiali Han, an associate professor at Harvard Medical School and Harvard School of Public Health in Boston. People in the study who drank decaffeinated coffee did not appear to have a lower risk of developing the skin cancer.
Additionally, the researchers found that the more caffeinated coffee that people in the study drank, the lower their risk of developing BCC, the most common type of skin cancer.
But the findings don't mean that your cup of joe can substitute for daily sunscreen.
"I would hope that people would not decide to spend a lot more time in the sun because they are drinking coffee," said Lorelei Mucci, an associate professor of epidemiology at the Harvard School of Public Health, who was not involved in the study. "There is a lot more about the prevention of BCC that we need to understand," Mucci said.
Caffeine and skin cancer
BCC accounts for about 80 percent of all skin cancer cases, according to the American Cancer Society. An estimated 2.8 million cases are diagnosed each year in the U.S., according to the Skin Cancer Foundation. BCC does not readily spread to other parts of the body, and so it is rarely deadly. Chronic exposure to the sun or ultraviolet radiation in tanning booths is the major environmental factor that causes BCC.
The researchers analyzed data gathered from 113,000 nurses and health professionals during two long-term studies. Study participants completed questionnaires about their diets, and provided information regarding their cancer risk factors, including family history of melanoma, sunburn reactions, complexion and exposure to direct sunlight. They were also monitored for signs of skin cancer.
Over the 20-year study, 22,786 participants developed basal cell carcinoma, while 1,953 developed squamous cell carcinoma and 741 participants developed melanoma.
The researchers found that the reduction in the risk of developing BCC seen in those who drank coffee was similar to the reduction in risk in people who consumed similar amounts of caffeine from other sources, including tea, chocolate and soda. Still, coffee was the major source of caffeine among the study population, accounting for 78.5 percent of all caffeine intake.
No link was found between caffeinated coffee intake and melanoma, the most deadly form of skin cancer, or squamous cell carcinoma (SCC). However, because the number of study participants diagnosed with melanoma or SCC were small, it is unclear whether caffeine truly has no effect on these skin cancers, or whether more time would be needed to see an effect, Han said.
"In another 10 years or more, it may be clearer whether caffeine also helps stave off these other types of skin cancer," Han said.
The study is not conclusive — it showed an association, not a direct cause-and-effect relationship between caffeinated coffee and skin cancer risk. Although mouse studies have shown that caffeine may prevent the development of SCC due to UV exposure, there is still no direct, convincing data showing coffee prevents skin cancer in people.
Han also emphasized that while it seems likely the benefit of the coffee comes from caffeine, researchers cannot yet know for sure. "There are lots of compounds in the coffee, including antioxidants. The process of decaffeination can wash out other compounds in the coffee, so we cannot 100 percent tease out that caffeine is the only factor responsible for the effect," Han said.

The Importance of WATER

The Importance of WATER



Water is the common name applied to the liquid form (state) of the hydrogen and oxygen compound H2O. Pure water is an odorless, tasteless, clear liquid. Water is one of nature's most important gifts to mankind. Essential to life, a person's survival depends on drinking water. Water is one of the most essential elements to good health -- it is necessary for the digestion and absorbtion of food; helps maintain proper muscle tone; supplies oxygen and nutrients to the cells; rids the body of wastes; and serves as a natural air conditioning system. Health officials emphasize the importance of drinking at least eight glasses of clean water each and every day to maintain good health.
Since water contains no calories and can serve as an appetite suppressant and helps the body metabolize stored fat, it may possibly be one of the most significant factors in losing weight. In his book, titled "The Snowbird Diet" Dr. Donald Robertson says the body will not function properly without enough water and discusses the importance of drinking plenty of water for permanent weight loss: "Drinking enough water is the best treatment for fluid retention; the overweight person needs more water than the thin one; water helps to maintain proper muscle tone; water can help relieve constipation; drinking water is essential to weight loss."
Water is a key component in determining the quality of our lives. Today, people are concerned about the quality of the water they drink. Although water covers more than 70% of the Earth, only 1% of the Earth's water is available as a source of drinking. Yet, our society continues to contaminate this precious resource. Water is known as a natural solvent. Before it reaches the consumer's tap, it comes into contact with many different substances, including organic and inorganic matter, chemicals, and o ther contaminants. Many public water systems treat water with chlorine to destroy disease-producing contaminants that may be present in the water. Although disinfection is an important step in the treatment of potable water, the taste and odor of chlorine is objectionable. And, the disinfectants that are used to prevent disease, can create byproducts which may pose significant health risks. Today, drinking water treatment at the point-of-use is no longer a luxury, it is a necessity! Consumers are taking matters into their own hands and are now determining the quality of the water they and their families will drink by installing a drinking water system that will give them clean, refreshing, and healthier water.
Properties: The freezing point of water is 0° C (32° F), and its boiling point is 100° C (212° F). Water reaches its maximum density at 4° C (39° F) and expands upon freezing. Water combines with salts to form hydrates and reacts with metal oxides to form acids (see Acids and Bases).
Occurrence: Water is the only substance that occurs at ordinary temperatures in all three states of matter: solid, liquid, and gas. As a solid, ice, it forms glaciers, frozen lakes and rivers, snow, hail, and frost. It is liquid as rain and dew, and it covers three-quarters of the earth's surface in swamps, lakes, rivers, and oceans. Water also occurs in the soil and beneath the earth's surface as a vast groundwater reservoir. As gas, or water vapor, it occurs as fog, steam, and clouds.
Water in Life: Water makes up 50 to 90 percent of the weight of living things. Protoplasm is a solution of water and fats, carbohydrates, proteins, and salts. Water transports, combines, and chemically breaks down these substances. Water also aids the metabolic breakdown of proteins and carbohydrates.
Natural Water Cycle: The continuous movement of water between the earth and the atmosphere is the hydrological cycle. Water vapor from water and land surfaces and from living cells circulates through the atmosphere and falls as rain or snow. When it reaches the earth, water either flows into streams and then into oceans or lakes, or it enters, or infiltrates the soil. Some water becomes soil moisture, which may evaporate directly or move up through the roots of plants and be released by leaves. Some water percolates downward, accumulating in the so-called zone of saturation to form the groundwater reservoir, the upper surface of which is the water table. Under natural conditions, the water table rises in response to inflowing water and then declines as water drains into natural outlets such as wells and springs.
Composition: Because water dissolves numerous substances in large amounts, pure water rarely occurs in nature. Precipitation absorbs carbon dioxide and other gases, as well as traces of organic and inorganic material from the atmosphere. Because water reacts with minerals in the soil and rocks, surface and groundwater may contain many different dissolved substances. Surface waters may also contain domestic sewage and industrial wastes. Groundwater from shallow wells may contain nitrogen compounds and chlorides, but water from deep wells generally contains only dissolved minerals. Seawater contains many soluble compounds in addition to salt.
Water Purification: Impurities are removed from water by screening, sedimentation, filtration, chlorination, or irradiation. See also Sewage Disposal. Aeration saturates water with air, usually by spraying fountains of water into the air. Aeration removes odors and tastes caused by decomposing organic matter, industrial wastes, and some gases. Various salts and metals cause hardness in water. Hardness may be removed by boiling, by adding sodium carbonate and lime, or by filtering through natural or artificial zeolites.
Water Desalinization: Three desalinization processes, which involve evaporating salt water and then condensing the resulting steam, are known as multiple-effect evaporation, vapor-compression distillation, and flash evaporation. Freezing is another desalinization method, based on the different freezing points of fresh and salt water. Ice crystals are separated from the salt brine, washed, and melted into fresh water. In reverse osmosis, pressure forces fresh water through a membrane that does not allow minerals to pass. In electrodialysis, the positive and negative ions of the dissolved salt are removed from water by an electric current through special membranes.
These fine drinking water systems reduce a wide range of contaminants of health concern for a low cost per gallon. The superior effectiveness of solid carbon block systems is confirmed by testing and certification by NSF International; independent laboratory tests; certification by the State of California Department of Health Services; and more importantly, by the more than two million satisfied customers throughout the world. The performance of the solid carbon block filter technology exceeds that of all other filter types and meets only the highest standards for quality!
