Development Smithsonian.jpg Temperature rise 'slows economy in poor countries' Last Updated on 2012-08-20 00:00:00 Paula Park reports in SciDev.Net on August 16, 2012, that [s]mall increases in temperature may have reduced the industrial and agricultural production of poor countries, according to a study by Melissa Dell and Benjamin A. Olken at MIT and Benjamin F. Jones at Northwestern University. Temperature rise 'slows economy in poor countries' Higher temperatures may also have contributed to political instability in these countries — defined as those with below-median per capita income, adjusted for the purchasing power of the country's currency — according to the study published in the American Economic Journal: Macroeconomics last month. In contrast, rich countries have so far shown no measurable economic or political consequences resulting from temperature change. "Temperature fluctuations can have large negative impacts on poor...

Namib Desert USGS.jpg Landsat at 40 Years Last Updated on 2012-07-24 00:00:00 The Longest Continuous View of Earth From Space Hits 40 The National Aeronautics and Space Administration (NASA) and the Interior Department have marked the 40th anniversary of the Landsat program, the world's longest-running Earth-observing satellite program. The first Landsat satellite was launched July 23, 1972, from Vandenberg Air Force Base in California. The 40-year Landsat record provides global coverage that shows large-scale human activities such as building cities and farming. The program is a sustained effort by the United States to provide direct societal benefits across a wide range of human endeavors, including human and environmental health, energy and water management, urban planning, disaster recovery and agriculture. Landsat images from space are not merely pictures. They contain many layers of data collected at different points along the visible... More »
MicrobeSampling NASA.jpg Advancing indoor microbial sampling Last Updated on 2012-06-05 00:00:00 Report Details Efforts to Improve, Advance Indoor Microbial Sampling Humans spend greater than 90 percent of their time indoors, but we're never alone there. Bacteria and viruses, scientists estimate, make up half of the world's biomass—some 10 nonillion (1 followed by 31 zeros) microorganisms—and we most often meet them within enclosed spaces. So, that's where the modern microbe hunter often looks first. A report issued by the National Institute of Standards and Technology (NIST) offers guidance to make the hunting more effective. A fundamental understanding of the microbial community in the built environment—including estimates of diversity, function and concentration—is necessary to accurately assess human exposure, and in turn, the potential impacts on human health. To address the many challenges associated with characterizing this... More »

ContentImg.jpg Amine gas treating Last Updated on 2011-10-07 00:00:00 Amine gas treating refers to a group of processes that use aqueous solutions of various alkanols (commonly referred to as simply "amines") to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gases. It is a common process unit used in petroleum refineries, natural gas processing plants, petrochemical plants and other industries. The process is also known as acid gas removal and gas sweetening. Processes within petroleum refineries or natural gas processing plants that remove hydrogen sulfide and/or mercaptans are commonly referred to as sweetening processes because they result in products which no longer have the sour, foul odors of mercaptans and hydrogen sulfide. There are many different amines used in gas treating: Monoethanolamine (MEA) Diethanolamine (DEA) Methyldiethanolamine (MDEA) Diisopropylamine... More »
