The subject of 'gas bubbles in liquids' has many applications in industry. Examples include separating oil from water in the oil industry, how ink drops behave in printers and the manufacture of products in the food industry, such as mayonnaise. 'This subject of course also applies to natural processes such as rainfall and boiling water,' PhD student Jok Tang adds.
Experiments
Waltham, MA–Scientists today sent the first beam of protons zooming at nearly the speed of light around the 17-mile Large Hadron Collider. The LHC, located at the CERN laboratory near Geneva, Switzerland, is the world's most powerful particle accelerator.
BOSTON, Mass. (Sep. 10, 2008)—In recent years, private equity investors have increasingly targeted nursing homes as investment opportunities. Spurred by investigative reports and anecdotal evidence that these deals led to worsened quality of care, many companies have found themselves under increased federal scrutiny.
Philadelphia, PA (Sept. 10, 2008) On the seventh anniversary of the September 11th attacks, what is the nature of the terrorist threat against the United States and other nations of the world and how should the next President address that threat upon taking office in January 2009? These questions are at the center of a special volume of The Annals edited by Richard A.
The phenomenon of "shimmering" in giant honeybees, in which hundreds—or even thousands—of individual honeybees flip their abdomens upwards within a split-second to produce a Mexican Wave-like pattern across the bee nest, has received much interest but both its precise mode of action and its purpose have long remained a mystery.
Bacteria can be used to break down used sheep dip, preventing bees and fish from dying because of soil and river contamination, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
Microbes that break down oil and petroleum are more diverse than we thought, suggesting hydrocarbons were used as an energy source early in Earth's history, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin. These microbes can change the composition of oil and natural gas and can even control the release of some greenhouse gases. Understanding the role of microbes in consuming hydrocarbons may therefore help us access their role in the natural control of climate change.
A new report co-authored by Rice political scientists Mark Jones and William Reed with colleagues at the University of Houston finds patterns and/or aberrations in the use of Tasers related to ethnicity, gender, race and geography.
COLUMBIA, Mo. -Without a way to measure religious beliefs, anthropologists have had difficulty studying religion. Now, two anthropologists from the University of Missouri and Arizona State University have developed a new approach to study religion by focusing on verbal communication, an identifiable behavior, instead of speculating about alleged beliefs in the supernatural that cannot actually be identified.
The world's intellectual property system is broken. It's stopping lifesaving technologies from reaching the people who need them most in developed and developing countries, according to the authors of a report released in Ottawa today by an international coalition of experts.
Anti-virus companies play a losing game. Casting their nets wide, they catch common, malicious viruses and worms (known to the industry as "malware"), but it may take days before their software updates can prepare your computer for the next attack. By then it could be too late. And some insidious programs prove immune to anti-virus software, residing inside your computer for months or even years, collecting personal information and business secrets.
Yeast fungus cells that kill thousands of AIDS patients every year escape detection by our bodies' defences by hiding inside our own defence cells, and hitch a ride through our systems before attacking and spreading, scientists heard today (Tuesday 9 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
A first-ever, national study conducted in South Africa found that 27.5 percent of men who have ever been married or lived with a partner report perpetrating physical violence against their current or most recent female partner. This study http://www.cmaj.ca/press/pg535.pdf,led by researchers from Harvard School of Public Health, Yale School of Public Health, and the University of Cape Town in South Africa, appears in the September 9, 2008, issue of CMAJ (Canadian Medical Association Journal.)
Patients visiting an ophthalmologist report that prayer is important to their well-being and that God plays a positive role in illness, according to a report in the September issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
A video lottery terminal In Montreal, a video lottery terminal (VLT) is often less than three minutes away by foot from a compulsive gambler, who is usually a male between 18 and 44 with little education and low revenues.
For instance, 96 percent of the Park Extension neighborhood has a business with a VLT permit less than three minutes away from the residential area, according to Université de Montréal geographer Éric Robitaille.
