Cornerstone to the W3C Speech Interface Framework is Nearly Complete
Giving voice to the Web, the World Wide Web Consortium (W3C) has published VoiceXML 2.0 as a W3C Proposed Recommendation. The goal of VoiceXML 2.0 is to bring the advantages of Web-based development and content delivery to interactive voice response applications.
Advancement of a W3C technical report to Proposed Recommendation indicates that the Working Group has successfully completed both public and W3C Wo
In der Praxis werden Biodiesel (RME) und fossiler Dieselkraftstoff (DK) sowohl in reiner Form als auch im Mischbetrieb eingesetzt. Es erhebt sich die Frage, inwieweit Mischungen beider Kraftstoffe eine nichtlineare Änderung der Emission über dem Mischungsverhältnis zur Folge haben. Verschiedentlich waren in der entsprechenden Literatur überproportionale Effekte vermutet bzw. sogar messtechnisch ermittelt worden.
Wenn sich die Emissionen von Mischungen aus Biodiesel und DK nicht proportional
The fog today is hanging heavy on the Yangtze River making conditions for navigation rather difficult, however one ferry goes forward with no special worries. The captain is using the highly accurate satellite navigation system, EGNOS.
The European Geostationary Navigation Overlay Service (EGNOS) is an initiative of the European Space Agency (ESA), the European Commission and Eurocontrol.
This boat trip is the first trial testing satellite navigation with EGNOS in China and is the first
Reducing the amount of fat in lamb amongst the Navarra variety of sheep in order to breed weightier animals, suitable for market demands and with a lower production cost for the farmer, is the aim of the project being developed by a research team from Navarre Public University’s Department of Agricultural Production and Department of Health Sciences.
The Navarre breed – previously known as Rasa Aragonesa – is found in the midlands region of Navarre and the extensive Ebro river basin region
Research into the reasons for the recent world-wide spread of the devastating animal disease, bluetongue, could have major implications for the long-term future of Australia’s sheep industry.
According to a senior epidemiologist at CSIRO Livestock Industries’ Australian Animal Health Laboratory in Geelong, Dr Peter Daniels, bluetongue disease is spreading rapidly in Europe and new strains of bluetongue virus have been detected in Australia.
“While Australian sheep are cu
The European Commission today adopted an action plan on GMES – Global Monitoring for the Environment and Security. The plan outlines firm steps towards the establishment of a system that will harness, co-ordinate and enhance existing Earth observation and monitoring information from satellites and Earth-based sensors, in order to support better decision-making for the environment and security. The initiative aims at providing independent, cost-effective, and user-friendly services that can help to a
For years, scientists theorized that a molecule called ClOOCl in the stratosphere played a key role in destroying ozone. Now, using measurements from a NASA aircraft laboratory flying over the Arctic, Harvard scientist Rick Stimpfle and colleagues observed the molecule for the first time. They report their discovery in the Journal of Geophysical Research-Atmospheres, published by the American Geophysical Union.
“We knew from observations dating from 1987, that the high ozone loss was link
The well-known extrasolar planet HD 209458b, provisionally nicknamed ’Osiris’, has surprised astronomers again. Oxygen and carbon have been found in its atmosphere, evaporating at such an immense rate that the existence of a new class of extrasolar planets – ‘the chthonian planets’ or ‘dead’ cores of completely evaporated gas giants – has been proposed.
Oxygen and carbon have been detected in the atmosphere of a planet beyond our Solar System for the first time. Scientists using th
The outermost layer of the skin – the epidermis – is a rapidly renewing tissue and relies on the regenerative capacity of keratinocytes. Skin grafts using human cultured epidermal cells have been successful in treating patients with severe skin wounds. The notion that the ability to regenerate functional epidermal tissue is an exclusive property of epidermal stem cells is a general assumption in the stem cell biology field. In the February 2 issue of the Journal of Clinical Investigation, Pritinder K
More research needed to identify those for whom benefit could outweigh risk of side effects
A new study has found that regular intake of aspirin does appear to be associated with a reduced risk of the type of colon polyps that can develop into cancer. However, since risk reduction was strongest with aspirin doses higher than those used to prevent cardiovascular disease, the researchers say further study is needed to determine for whom the benefits of such treatment would outweigh any
Downward trend likely to continue says international research team
Stomach cancer rates fell by half in the European Union between 1980 and 1999 and by 45% in Eastern Europe and 40% in Russia, according to research published (Tuesday 3 February) in Annals of Oncology[1].
Encouragingly, the downward trend is set to continue, at least for the near future according to researchers, because the fall is seen in younger and middle aged people as well as the elderly.

In a report set for publication in the journal Biology of Reproduction, scientists at the University of Pennsylvania and the University of California, Davis, describe a technique that yields fertile primate sperm when tissue from the testes of young rhesus monkeys are grafted into mice.
The research team, headed by Dr. Ina Dobrinksi of the Center for Animal Transgenesis and Germ Cell Research in the School of Veterinary Medicine, University of Pennsylvania, believes that this method could b
A Portland company is using an emerging microtechnology from Oregon State University to develop a portable kidney dialysis machine that will make in-home treatment a reality, enabling hundreds of thousands of people afflicted with kidney failure to treat themselves at home instead of traveling to dialysis clinics three days a week.
“Current dialysis machines are based on 30-year-old technology and employ filter systems that are only about 28 percent efficient,” said Michael Baker, chief exec
After years of searching for a rare African primate, anthropologist Scott McGraw and his colleagues believed that the Miss Waldron’s red colobus monkey, Procolobus badius waldroni, was probably extinct. They had written a paper in 2000 saying so.
But recent hard evidence of the Miss Waldron’s red colobus’ existence has rekindled McGraw’s hopes of finding the primate, reportedly last seen in 1978. McGraw, an associate professor of anthropology at Ohio State University, det
An MIT device that makes the world’s most precise rulers—with “ticks” only a few hundred billionths of a meter apart—could impact fields from the manufacture of computer chips to space physics.
The Nanoruler is 10 to 1,000 times faster and more precise than other methods for patterning parallel lines and spaces (known collectively as gratings) across large surfaces more than 12 inches in diameter. Such large surfaces are key to a number of applications involving gratings, such as larger waf
Scientists from the Glenn T. Seaborg Institute and the Chemical Biology and Nuclear Science Division at the Lawrence Livermore National Laboratory, in collaboration with researchers from the Joint Institute for Nuclear Research in Russia (JINR), have discovered the two newest super heavy elements, element 113 and element 115.
In experiments conducted at the JINR U400 cyclotron with the Dubna gas-filled separator between July 14 and Aug. 10, 2003, the team of scientists observed atomic decay
