(Press-News.org) Washington, D.C. (January 11, 2011) -- A straightforward new way to calculate, compile, and graphically present solar radiation measurements in a format that is accessible to decision makers and the general public has been developed by researchers at the University of Texas at Austin.
The method presents solar data in a framework that "can be used by policymakers, businesses, and the public to understand the magnitude of solar resources in a given region, which might aid consumers in selecting solar technologies, or policymakers in designing solar policies," says David Wogan, a graduate student in mechanical engineering and public affairs at the University of Texas at Austin and the first author of a paper about the work in the American Institute of Physics' Journal of Renewable and Sustainable Energy.
Wogan's coauthors on the paper are Michael E. Webber, an assistant professor of mechanical engineering and the associate director of the Center for International Energy and Environmental Policy, and Alexandre K. da Silva, an assistant professor of mechanical engineering.
The method uses calculated estimates of solar insolation—the amount of solar radiation incident on the earth's surface—and the total energy in each of Texas's 254 counties, and presents the data in a geographic information system (GIS) format. Included in the model are daily, monthly, and yearly averages. This allows the method to be used, for example, to estimate the potential amount of solar-generated electricity that could be produced at a given location, in a given month.
In the paper, the researchers use Texas to illustrate the new method, "because its geography is very diverse," Wogan says, "but the framework is not limited to Texas and can be expanded to other states and countries to understand how renewable energy resources are distributed, both geographically and through time."

Washington, D.C. (January 11, 2011) -- High energy costs are one drawback of making clean water from waste effluents. According to an article in the journal Biomicrofluidics, which is published by the American Institute of Physics, a new system that combines two different technologies proposes to break down contaminants using the cheapest possible energy source, sunlight. Microfluidics – transporting water through tiny channels -- and photocatalysis -- using light to break down impurities – come together in the science of optofluidics.
"These two technologies have been ...
Washington, D.C. (January 11, 2011) -- Whether the object of attention is a novel aspect of the universe or an enigmatic and distant colleague, listening is key to nearly any effort to seek understanding. And not just with your ears. Spectroscopy, the study of how atoms absorb and emit electromagnetic radiation, is like listening, too. The technique is central to a range of physics experiments and can be thought of as an attempt to filter out useful information from what various sensors and detectors often first "hear" as undifferentiated electromagnetic noise.
Now, ...
Under the electron microscope, a coronavirus may resemble a spiny sea urchin or appear crownlike, (the shape from which this family of pathogens takes its name). Previously recognized as the second leading cause of the common cold in humans and for economically important diseases in many domesticated animals, a new disease form abruptly emerged as a major public health concern in 2002, when the SARS coronavirus (CoV) surfaced in Asia.
The rapid spread of the virus caused significant social and economic disruption worldwide , infecting over 8000 people with Sudden Acute ...
Multiple sclerosis (MS) is a disease caused by damage to myelin – the protective covering wrapped around the nerves of the central nervous system (CNS).
Previous studies have shown that certain white blood (immune) cells, called leukocytes, infiltrate the CNS and play a significant role in causing the damage that contributes to MS symptoms. It has also been shown that these leukocytes enter the CNS with help from a family of molecules called MMPs.
Using a mouse model, researchers have discovered that a molecular switch called EMMPRIN plays an important role in MS. The ...
Tampa, Fla. (Jan. 10, 2011) – Transplanting their own (autologous) bone marrow-derived stem cells into 48 patients with end-stage liver disease resulted in therapeutic benefit to a high number of the patients, report researchers publishing in the current issue of Cell Transplantation (19:11). Yet, the mechanism by which the infusion of CD34+ stem cells improves liver function remains elusive, they say.
The study, carried out by a team of researchers in California and in Egypt, is now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/.

A team of chemists headed by Thomas Loerting from the University of Innsbruck and Hinrich Grothe from the Vienna University of Technology (TU Wien) in Austria have prepared and isolated gas-phase carbonic acid and have succeeded in characterizing the gas-phase molecules by using infrared spectroscopy. The results were published in the journal Angewandte Chemie International Edition.
In textbooks and other media the widespread belief still prevails that stable carbonic acid cannot be produced in pure form and is practically non-existent as it immediately decomposes to ...
Small children are capable of engaging in issues concerning sustainable development.Their interests and rights must be better safeguarded in rules and policy decisions that concern the education of the youngest groups of children within the EU.
This is emphasised in the report "Taking children seriously – How the EU can invest in early childhood education for a sustainable future", which was presented at a seminar in Brussels on Friday 17 December.
The body behind the report is the European Panel on Sustainable Development (EPSD), an independent research-based network ...
Berkeley — It will come as no surprise to dog owners that their four-legged friends have a flair for sniffing out the excrement of other animals. Now, biologists at the University of California, Berkeley, have trained dogs to detect the scat of other critters for the greater good – to conduct more accurate surveys of wildlife.
"Wildlife detection dogs have been mostly used in airports to detect contraband, including endangered species and wildlife products, but in recent years, interest has grown in using the dogs to help scientists track biological targets in natural ...
One of the challenges of gene therapy - a set of methodologies aimed at treating several nucleic acid diseases (DNA or RNA) - is to assure that this material arrives directly to the nucleus of the cell without losing a substantial amount along the way and without producing any undesired side effects. With this aim, scientists experiment with the use of different types of vectors, molecules capable of transporting genetic material to the correct place. Presently, natural "deactivated" viruses are the most commonly used vectors in clinical trials, their side effects however ...
Researchers at the University of Gothenburg, Sweden, have developed new methods for analysing medical databases that can be used to identify diagnostic markers more quickly and to personalise medication for allergic disorders. They could also reduce the need for animal trials in clinical studies.
Published in the journal PLoS Computational Biology, the study builds on data analyses of freely available medical databases representing studies of countless numbers of patients in the
PubMed database, and microarray data in another major database. The use of microarrays is ...
