AT&T fleet program provides case study ANN ARBOR, Mich., Oct. 6 /PRNewswire-USNewswire/ -- The "greening" of corporate vehicle fleets presents an opportunity to move a substantial number of highly efficient, clean fuel vehicles onto the road in a relatively short timeframe -- with results that are both environmentally and economically positive. A newly released report by the Sustainable Transportation and Communities group at the Center for Automotive Research (CAR), an Ann...

Nuclear magnetic moment is one of the most important physical observables. The precise measurement of nuclear magnetic moment and its understanding in microscopic way are quite a challenge in nuclear physics. The research team at Peking University, who has dedicated to the study of nuclear structure and astrophysics for the last decades, has applied the configuration-fixed deformation constrained RMF approach with time-odd component to investigate the ground-state properties of 33Mg and...

Researchers from the Helmholtz-Zentrum Berlin fr Materialien und Energie have, in cooperation with colleagues from Dresden, St. Andrews, La Plata and Oxford, for the first time observed magnetic monopoles and how they emerge in a real material. They publish this result in the journal Science within the Science Express web site on Sept. 3. Magnetic monopoles are hypothetical particles proposed by physicists that carry a single magnetic pole, either a magnetic North pole or South pole. In the...

Researchers from Wageningen University used the warm days in August to map out the urban climate in two Dutch cities. The research team drove two cargo bicycles with measurement equipment during various times of a 24 hours' day through Rotterdam and Arnhem. The results may indicate to which extent heat stress may become a problem for the inhabitants.Future projections of climate change show  that frequency of heat waves will increase substantially in the next decades. Particularly in...

The Chevrolet Volt electric car may earn a fuel-efficiency rating of 250 miles per gallon, U.S. automaker General Motors Co. said Tuesday. GM has been working with the Environmental Protection Agency for several years on how to rate the mileage of the Volt, which runs on electricity, but includes a gas-powered engine that generates extra electricity for trips longer than 40 miles, CNNMoney.com reported. Essentially, the Volt will drive the first 40 miles on an electric charge alone. After...

Water is familiar to everyone"”it shapes our bodies and our planet. But despite this abundance, the molecular structure of water has remained a mystery, with the substance exhibiting many strange properties that are still poorly understood. Recent work at the Department of Energy's SLAC National Accelerator Laboratory and several universities in Sweden and Japan, however, is shedding new light on water's molecular idiosyncrasies, offering insight into its strange bulk properties.In all,...

Yale University researchers say they've discovered a repulsive light force that can be used to control components on silicon microchips. The scientists said their finding is important because it means future nanodevices might be controlled by light rather than electricity. The same Yale team of scientists previously discovered an attractive force of light and showed how it could be manipulated to move components in semiconducting micro- and nano-electrical systems. Now they've discovered a...

Since its discovery just a few years ago, graphene has climbed to the top of the heap of new super-materials poised to transform the electronics and nanotechnology landscape. As N.J. Tao, a researcher at the Biodesign Institute of Arizona State University explains, this two-dimensional honeycomb structure of carbon atoms is exceptionally strong and versatile. Its unusual properties make it ideal for applications that are pushing the existing limits of microchips, chemical sensing instruments,...

Leaving a child in a hot car is like leaving a child in a lit oven, a U.S. emergency physician warns. Dr. Nick Jouriles, president of the American College of Emergency Physicians, says children throughout the country die each year as a direct result of being left alone in a hot vehicle. The most important thing to know is that it does not have to be brutally hot outside for it to be brutally hot inside the car, Jouriles said in a statement. A vehicle's window will act like a greenhouse,...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
