More Efficient Production Of Electricity, Cold And Heat
Some large installations - sports centre, hotels and large industry - already use systems capable of generating both electricity and refrigeration for air conditioning and heat for heating and hot sanitary. This integrated, trigeneration system provides significant energy and environmental advantages. However, for domestic use, its installation meets a number of problems. With its participation in PolySMART, the IKERLAN-IK4 Centre for Technological Research aims to overcome these difficulties and barriers to the home installation of the energy-saving technology and demonstrate that is economically, technically and environmentally viable to adapt these installations to individual household consumption. Its main objective is to achieve a single installation that supplies all the energy demands in our homes. To this end, other centres of reference in the field of energy in buildings are collaborating, such as the German Fraunhofer-ISF or the Dutch ECN. Another two companies from the Spanish State are working together with IKERLAN-IK4 - Rotartica and Besel......... Posted by: Tom Permalink Source Insights Into Scientific Revolution
"Einstein did not achieve this revolution by means of a single stroke of genius-rather, he stood on the shoulders of dwarves and giants", says Jürgen Renn. Volumes 1 and 2 contain the facsimile and transcription of, as well as a scholarly commentary on, Einstein's famous Zurich Notebook from 1912-1913. The research by Einstein recorded in this notebook forms a pivotal part of his creation of the theory of general relativity. Complementing this core material are essays re-evaluating the genesis of Einstein's theory in light of the analysis of this notebook. Volumes 3 and 4 contain additional sources by Einstein and his contemporaries, who from the late nineteenth to the early twentieth century contributed to this groundbreaking development. These sources, most of which are presented here in translation for the first time, are accompanied by essays by leading historians of relativity offering new insights into the broader scientific context from which Einstein's theory emerged. The result of more than a decade of research, these four volumes provide a study of unprecedented depth of one of the most important revolutions in the history of science......... Posted by: Tom Permalink Source Hurricane Season Adds to Red Tide
The four hurricanes that crossed the Sunshine State in August and September 2004 dumped as much as 27 inches of rain (nearly double the historical values) in central Florida, which increased groundwater levels and rates of surface runoff. These two factors are thought to create conditions ripe for the bloom of a red tide. Red tides, which may or may not be harmful, are primarily caused by the toxic phytoplankton, Karenia brevis on the west Florida Shelf. This species of phytoplankton can produce toxins that can kill marine organisms and lead to irritation of the eye and respiratory systems of animals and people. Researchers Chuanmin Hu and Frank Muller-Karger of the University of South Florida, St. Petersburg, Fla., and Peter Swarzenski of U.S. Geological Survey, St. Petersburg, Fla., noted that several factors may have contributed to the 2005 red tide: the 2004 hurricanes and their heavy rain, runoff, and submarine (below the ocean floor) groundwater discharge. The researchers used NASA satellites, as well as observations from ships, buoys from the National Oceanic and Atmospheric Administration (NOAA), and geochemical tracers to study red tide.........

The research is presented in a symposium entitled "Gapology and the Presidential Vote," edited by Laura R. Olson (Clemson University) and John C. Green (University of Akron). In four articles, scholars explore a different voter gap in detail. The entire symposium appears in the recent issue of PS: Political Science & Politics, a journal of the American Political Science Association (APSA), and is available online at /section_694.cfm. "We aim to show that 21st-century Americans are divided on a wide range of political fronts that go far beyond the. 'red state, blue state' rubric that has become so popular," state the editors; "reality. is far more complex". The religion gap was one of the most significant recent trends among voters. In their article, Olson and Green reflect on the tendency of the most religious Americans to espouse conservative political beliefs and support the GOP. Their analysis finds there was "no sustained 'religion gap' in voting behavior until 1992," after which "differences within religious communities were. apparently more politically significant than differences among religious traditions." The 2004 voting data reveal a significant gap where "one-half of all Bush's ballots were cast by weekly worship attendees, whereas some two-thirds of Kerry's votes were cast by less-than-weekly attendees." However, the authors argue for a nuanced interpretation of the data given that 41.2% of weekly worship attendees claim they have a moderate political ideology and nearly as a number of chose economic issues as their top policy concern (34.3%) as did moral issues (34.4%).........

On the plus side, he is wearing a hard hat. Also, if you look carefully at the boulder's 4 o'clock, you'll see a plastic drink bottle propped on another rock, so he is also staying hydrated. And maybe that boulder is actually 20 feet long, so that's just the tip sticking out. Yeah, that's it......... Posted by: Tom Permalink S-VIEW SV510 portable video key
Should the USB key be lost or stolen, this device can be disconnected remotely. Movie studios should look into this offering from Cinea in order to reduce the risk of piracy. The S-VIEW SV510 comes with a six to twelve digit access code for security purposes and can be deregistered should the situation call for it......... Posted by: Gina Permalink Source iOPS BlueQ Digital Audio Player
So here we have the iOPs BlueQ, the DAP formerly known as Q18. Obviously equipped with a color screen (1.8-inch, 262k colors) and (supposedly so) runs for about 30 hours when playing audio (MP3/WMA). Most "unique" feature would have to be the bluetooth support, enabling us all to jam through our 70s'esque living rooms, kicking furniture through the plastic ceiling and all that - without being bothered by those nasty headphone wires. It remains to be seen if iOPS can actually crank up the capacity volume to the respectable 4GB level (as promised before) - but all in all, the BlueQ doesn't look half bad. Some will call it a toy, others are likely to nickname it "fatty". that's the way life is, even for DAPs. At least it's smaller than a coffee mug......... Posted by: Gina Permalink Source Solving Mysteries in Helicopter Parts
Under a NASA Space Act Agreement, the Materials and Processes Laboratory of Marshall Space Flight Center's Engineering Directorate is partnering with the Army Aviation Engineering Directorate, U.S. Army Aviation and Missile Research, Development and Engineering Center at Redstone Arsenal to conduct failure analysis on helicopter parts. The project taps Marshall's capabilities and expertise in metallurgy -- the science of metals. The lab is analyzing such items as engine parts, main rotor parts and fasteners from Army helicopters that have flown in the war in Iraq and Afghanistan. The parts under scrutiny are those that have experienced some type of failure with the metal product forms such as castings, forgings or extrusions. The helicopter hardware is studied on a microscopic level, because most problems in the metal can't be seen with the naked eye. Parts from Apache, Blackhawk, Chinook and Observation helicopters are analyzed in Marshall's state-of-the-art failure and analysis diagnostic facility. The facility uses high-powered microscopes to uncover the root cause of the problem, whether it's the way the part was machined, heat-treated or formed and fitted. The engineers also use fractography to characterize the fracture surfaces of the failed parts......... Posted by: Jim Permalink Source Policing Baghdad
Davis' paper, "Policing, Regime Change and Democracy: Reflections From the Case of Mexico," also offers a cautionary tale to policymakers: Establishing security at the expense of civil rights can "set a country on a downwardly spiraling slippery slope of armed conflict and deteriorating rule of law," she writes. Q: How are the cities of Baghdad today and Mexico City in 1910 similar? A: Both have been capital cities caught in the crossfire of national struggles for regime change. Both cities also struggled with the general goal of establishing democracy in the face of conflicts over the new political order. New political leaders in both cities and countries have had to replace the military with police forces. Both faced political turmoil and chaos following the departure of their former regime leaders, and citizens in both Mexico City and in Baghdad clamored for protection from violence and for a viable police force to restore domestic security. As in Iraq today, in the face of a partially armed citizenry and a still unconsolidated regime change, Mexico's post-revolutionary political leaders had little recourse but to..... patch together a rough and tumble police force comprised of personnel they thought they could trust. A number of of the police were rural folk, with little understanding of policing, of city life, of the law or how to guarantee it......... Posted by: Tom Permalink Source The Man Who Created The Look And Feel Of 'bladerunner'
Easily in my all-time top 10 pantheon of movies, "Bladerunner" blew me away when I first saw it. I watched the long-awaited "Director's Cut" last year and though it was a much more understandable narrative, oddly enough it wasn't nearly as compelling a film as the original version. Perhaps the suits in the executive suites get it right once in a while. But I digress. A documentary, "Visual Futurist: The Art and Life of Syd Mead," premieres this coming Sunday, July 23 in Los Angeles......... Posted by: Gina Permalink Source |
