Dirty Politics in Karnataka ? What's cooking up??
Almost everybody is aware of the dirty politics in Karnataka recently that shook the entire country and its political scenario. It was only in the month of October 2010 that Karnataka Chief Minister B.S.Yeddyurappa terminated few of his cabinet ministers for rebelling and withdrawing their support to his 29 months old government. Owing to this burning issue, more BJP MLAs withdrew their support for Yeddyurappa government, followed by five more independent MLAs rebelling against him. With such displeasure in Karnataka political scenario, a confidence vote has to be conducted on 12th October 2010.
However, there were more displeasures to follow, revealing the dirty politics in Karnataka. The state governor H R Bharadwaj gave advice to Karnataka assembly speaker K G Bopaiah not to terminate or disqualify any MLAs.
But in 12th October 2010 morning, the speaker disqualified all the 16 MLAs rebelling against Karnataka Chief Minister. The assembly strength reduced to 208 from 224 members, calling for a voice voting that was conducted by the assembly speaker and BJP, who has support of 106 MLAs. No wonder, BJP was declared a clean winner with its support from the MLAs. Again this trust vote results induced dissatisfaction among JD party and the so called ruled party, Congress as well, declaring the process to be unfair and a blot on Indian democracy.But this was not the end to it. The Karnataka Governor, Bharadwaj, a pro-Congress member, came to the limelight for some time due to all wrong things happening in the state political scenario.
Owing to Karnataka?s Chief Minister?s win in disqualifying 16 MLAs from the assembly and BJP winning the trust vote with the support of 106 MLAs, Bharadwaj took a politically motivated and unprecedented decision by sanctioning the petition to prosecute Karnataka Chief Minister, B S Yeddyurappa. The state cabinet had passed a resolution earlier, urging the governor to terminate the prosecution petition, but Bharadwaj stick to his political collision and declared that the cabinet is trying to hide the corruption allegations.According to some experts and top politicians, Karnataka Governor is acting much beyond the true nature of a state governor, and this incident is again portraying how Congress is actually misusing the power in their hands. This party has been in limelight for some time now, owing to several scams and political displeasure. It is believed that by prosecuting Yeddyurappa, Congress is trying to ward off the scam attention from them, and put BJP on the same dock as theirs. This clearly reflects the dirt politics in Karnataka building up for some time now.

Zoocasa Real Estate Blog: Before you buy, consider the ?heart and ...
With interest rates at all time lows and given the compelling and encouraging trend towards energy efficiency and green products in the new home building market, there really has never been a better time to buy a brand new home
New homes offer attractive features: bright, big windows; fresh, clean designs; modern, family-oriented layouts; and, of course, all the latest technical elements such as thick blankets of insulation and carefully controlled air leakage. Dig a little deeper and you will learn that there have also been some remarkable advances in the mechanical systems that provide for the comfort needs of new home buyers.
The heating, ventilation and air conditioning (HVAC) systems in modern, high performance homes have undergone a transformation from what you may remember as that big, noisy sheet metal beast in the basement to being an integral part of a safe, healthy, controlled cozy living environment for the busy family looking for a peaceful oasis at home. You really owe it to yourself to consider carefully the options available in what might best be described as the ?heart and lungs? of the home.
First, the energy efficiency of heating and cooling equipment has increased by about 30% over the last decade or two. Virtually all new homes boast furnaces with efficiencies of at least 90% and the most progressive home builders will be offering equipment that squeezes up to 96% of the available energy out of every dollar you spend on energy.
More remarkable is that these new heating systems are able to maintain that efficiency throughout the entire season. New variable output technologies allow furnaces to adapt to changing weather to ensure you get just the amount of heat you need to keep your family comfortable throughout your home. Even better, variable output furnaces employ a breakthrough fan motor technology that cuts the electrical consumption of your gas or oil furnace by as much as 60%. These new fans are much quieter, last longer and provide an even flow of conditioned, filtered air year round.
Similarly, a new generation of air conditioning equipment is ideally suited to new homes. The ?seasonal energy efficiency rating? (SEER) of new air conditioning systems is up 30% as well over the last decade. The latest Energy Star rated AC systems have a SEER rating of 14.5, a 45% improvement over commonly sold AC units just 10 years ago. Combined with the new variable speed fan motors in the furnace, advanced cooling systems effectively suck humidity out of the air. This means no more sweaty, sleepless nights and damp, musty basements in the summer time.
Finally, be sure to ask your new home builder about the benefits of a ?fresh air machine?, known in the industry as a ?heat recovery ventilator? or HRV. These devices can be described as the mechanical lungs of your home and have become the appliance of choice for builders who want to ensure homeowners are getting a steady supply of fresh, filtered air in the home. These devices are a Canadian technology that in the past was reserved for only the most advanced, energy-efficient homes. Now they are a critical part of a healthy indoor environment. Homeowners now have control over the air their family breathes without having to worry about opening windows on cold, wet or hot humid, smoggy days.
These are just three of the exciting new HVAC options available as you research and identify features of your new home. Be sure to ask your builder about other options available, such as zoning, smart thermostats and controls and other technologies that will enhance the safety, comfort, health and durability of your new home.

From the ashes, the oldest controlled fire
South Africa cave yields earliest evidence of human ancestors lighting blaze
Web edition : 4:16 pm
A 1 million-year-old fire lit by human ancestors has flickered back to life in a South Africa cave.
Microscopic plant ashes and burned bone bits in Wonderwerk Cave come from soil that previously yielded several dozen stone tools, say archaeologist Francesco Berna of Boston University and his colleagues. A member of the Homo genus, perhaps Homo erectus, made a fire that produced those remains, the researchers write April 2 in the Proceedings of the National Academy of Sciences.
Berna?s team regards its data as the oldest secure evidence for controlled fire use. The ashes and charred bone ? unearthed earlier in Wonderwerk Cave by Peter Beaumont of the McGregor Museum in Kimberley, South Africa ? show no signs of having been carried there by wind, water or wildfires.
Although it?s unclear exactly how members of an extinct Homo species used this fire, the new findings fit with an idea that Homo erectus began to cook food nearly 2 million years ago, the scientists propose.
And human ancestors may have had other reasons for taming fire. ?Socializing around a campfire might be an essential aspect of what makes us human,? says archaeologist and study coauthor Michael Chazan of the University of Toronto.
An age estimate for the Wonderwerk fire largely comes from measurements of radioactive elements in soil that signal how long ago dirt covered the burned material. Molecular characteristics of burned bone fragments show they were heated to about 500? Celsius, consistent with a controlled fire of some kind, the researchers say.
Several stone artifacts from the same ancient soil display fractures produced by heating during tool production.
Human ancestors were probably responsible for the Wonderwerk Cave fire, but fires were not produced regularly that far back in the Stone Age, say archaeologists Wil Roebroeks of Leiden University in the Netherlands and Paola Villa of the University of Colorado Boulder. Remains of a hearth or campfire area, where fires would repeatedly have been lit, have not turned up in Wonderwerk Cave.
?Fire use was not a skill that was transmitted from generation to generation, over long periods of time, all over the Old World prior to about 400,000 years ago,? Roebroeks and Villa say.
Early Homo species survived in cold parts of Europe more than 400,000 years ago without habitually using fires, Roebroeks and Villa wrote in a recent review of hundreds of archaeological sites dating to between 1.2 million and 40,000 years ago.

Coral links ice sheet collapse to ancient 'mega flood'
ScienceDaily (Apr. 3, 2012) ? Coral off Tahiti has linked the collapse of massive ice sheets 14,600 years ago to a dramatic and rapid rise in global sea-levels of around 14 metres.
Previous research could not accurately date the sea-level rise but now an Aix-Marseille University-led team, including Oxford University scientists Alex Thomas and Gideon Henderson, has confirmed that the event occurred 14,650-14,310 years ago at the same time as a period of rapid climate change known as the B?lling warming.
The finding will help scientists currently modelling future climate change scenarios to factor in the dynamic behaviour of major ice sheets.
A report of the research is published in this week's Nature.
'It is vital that we look into Earth's geological past to understand rare but high impact events, such as the collapse of giant ice sheets that occurred 14,600 years ago,' said Dr Alex Thomas of Oxford University's Department of Earth Sciences, an author of the paper. 'Our work gives a window onto an extreme event in which deglaciation coincided with a dramatic and rapid rise in global sea levels -- an ancient 'mega flood'. Sea level rose more than ten times more quickly than it is rising now! This is an excellent test bed for climate models: if they can reproduce this extraordinary event, it will improve confidence that they can also predict future change accurately.'
During the B?lling warming high latitudes of the Northern hemisphere warmed as much as 15 degrees Celsius in a few tens of decades. The team has used dating evidence from Tahitian corals to constrain the sea level rise to within a period of 350 years, although the actual rise may well have occurred much more quickly and would have been distributed unevenly around the world's shorelines.
Dr Thomas said: 'The Tahitian coral is important because samples, thousands of years old, can be dated to within plus or minus 30 years. Because Tahiti is an ocean island, far away from major ice sheets, sea-level evidence from its coral reefs gives us close to the 'magic' average of sea levels across the globe, it is also subsiding into the ocean at a steady pace that we can easily adjust for.'
The research is part of a large international consortium, the Integrated Ocean Drilling Program (IODP), and the coral samples were obtained by drilling down to the sea floor from a ship positioned off the coast of Tahiti.
What exactly caused the B?lling warming is a matter of intense debate: a leading theory is that the ocean's circulation changed so that more heat was transported into Northern latitudes.
The new sea-level evidence suggests that a considerable portion of the water causing the sea-level rise at this time must have come from melting of the ice sheets in Antarctica, which sent a 'pulse' of freshwater around the globe. However, whether the freshwater pulse helped to warm the climate or was a result of an already warming world remains unclear.

Study shows bariatric surgery improves, reverses diabetes
Monday, March 26, 2012
Overweight, diabetic patients who underwent bariatric surgery achieved significant improvement or remission of their diabetes, according to new research from Cleveland Clinic.
In a randomized, controlled trial, some weight loss surgery patients achieved normal blood sugar levels without use of any diabetes medications. In others, the need for insulin to control blood sugar was eliminated. Recent observational studies had demonstrated that bariatric surgical procedures reduce the incidence of type 2 diabetes and lead to substantial improvement for many patients with pre-existing disease.
"After one year, patients who underwent gastric bypass or sleeve gastrectomy lost more weight and were significantly more successful at controlling their diabetes, compared to those who simply took medications," said lead investigator Philip Schauer, M.D., Director of the Cleveland Clinic Bariatric and Metabolic Institute. "We believe that bariatric surgery represents a potentially valuable strategy for control of diabetes that should be considered in more patients who do not respond to conventional treatment."
Results of the STAMPEDE (Surgical Therapy And Medications Potentially Eradicate Diabetes Efficiently) trial were published today in The New England Journal of Medicine and presented today at the Annual Scientific Sessions of the American College of Cardiology in Chicago.
The STAMPEDE trial involved 150 patients with obesity and poorly controlled diabetes. The patients were divided into three groups of 50: those who received intensive medical therapy of their diabetes, those who received intensive medical therapy plus gastric bypass surgery, and those who received intensive medical therapy plus sleeve gastrectomy.
"This trial demonstrates that bariatric surgery can eliminate the need for diabetes medications in many obese patients whose diabetes is poorly controlled," Schauer said. "Furthermore, the surgical patients showed major improvements in other measures of heart health, including reduced need for high blood pressure and cholesterol medications, while significantly boosting HDL ? the so-called 'good' ? cholesterol."
Effectiveness was gauged by the percentage of patients who achieved an average blood sugar within the normal range 12 months after treatment (measured using the hemoglobin A1c ? HbA1c ? a standard laboratory test that reflects average blood sugar over three months).
After 12 months, a normal HbA1c (less than 6.0) was achieved in 42.6 percent of patients who underwent gastric bypass and 36.7 percent of patients who underwent sleeve surgery, but just 12.2 percent of medically treated patients. The HbA1c of less than six is a more aggressive target than the American Diabetes Association guidelines.
Participants entered the study taking an average of three medications each for diabetes. In all of the gastric bypass patients who achieved the target level, the normal blood sugar was attained without use of any diabetic medications. Seventy-two percent of sleeve patients who reached normal blood sugar also did so without the use of any diabetic medications. In surgically-treated patients who continued to require drugs, researchers observed a substantial reduction in the need for diabetic medications.
As expected, the patients who received bariatric surgery lost more weight during the 12-month study, averaging 64.7 pounds for patients who received gastric bypass, 55.2 pounds for patients who had stomach reduction surgery, and 11.9 pounds for patients treated with medications.
The study authors reported some complications of surgery, but most were not serious. However, four patients did require a second operation. The study authors caution that the favorable results were observed after a relatively short follow-up period (12 months) and that long-term studies are needed to determine the durability of the findings. The authors will continue to follow these patients for four years to attempt to answer these questions.
