The lamp charges in about three or four hours of direct sunlight, and then the 0.18-watt solar cells provide six hours of LED lighting. The lamp, covered in a weatherproof UV-ABS casing, has an adjustable head that can easily be turned to face the sun. A sensor switches the light on when it detects darkness, so the lamp doesn’t waste energy during the day. By filling the bottle up with water, users can further amplify the light, and also weigh it down in windy locations. The company hopes that the solar-powered 0.07-watt high-output LEDs with a magnifying lens will provide an energy-efficient and visually appealing alternative as outdoor walkway lights and other applications. The Solarbulb is not yet for sale, but is expected to cost about $25 and come in a variety of colors.More information: Miniwiz.comvia: Ecogeek.com Solarbulb will come in a variety of colors and screw onto a typical water or soda bottle to diffuse the light.

Combination of technologies works best against E. coli Scientists Han Uhm of Ajou University in Korea, along with Kwang Lee and Baik Seong of Yonsei University in Korea, have published the results of their study on the H1N1 disinfectant in a recent issue of Applied Physics Letters. Besides being environmentally benign, AOW also has the advantage that it may cost significantly less to prepare compared with chemical disinfectants.During the past several months, H1N1 has infected thousands of people worldwide and has proven to be a highly contagious disease. Attempts to combat the disease have included preventative vaccines and the use of disinfectants to prevent the spread of the disease. However, most of these disinfectants have chemicals that can harm the environment.In the current study, the researchers found that they could make neutral water acidic by mixing a very small amount of hydrochloric acid into the water. Adding just 22 grams of hydrochloric acid to one ton of neutral water can change the pH value of the water from 7 to 4. As the scientists explain, the negative chlorine ions have a sterilizing effect on viruses, and a strong acidity in general also has a sterilizing effect. Although acidic water itself can partially inactivate the H1N1 virus, the scientists also added an ozone gas concentration of more than 10 mg/liter to the water to enhance the sterilization effect. All the viruses were killed after five minutes of mixing the acidic ozone water with about 430,000 viruses in the environment. When observing the number of viruses killed in a given time, the researchers found that the acidic ozone water had a synergic effect, outperforming the sum of the individual effects of acidic water and ozone water. Part of the reason for the enhanced sterilization is that, while ozone decays over time due to impurities, the acidification of water slows the decay, prolonging the time of disinfection. In another experiment, the researchers found that E. coli cells treated with acidic ozone water at pH 4 and an ozone concentration of 20 mg/liter destroyed the cell envelopes. Based on this observation, the scientists speculate that acidic ozone water may work by destroying the H1N1 virus envelopes, disabling their ability to establish an infection.“Most of the virus inactivation experiments in our lab have been conducted using the host cells for viruses,” Uhm told PhysOrg.com. “The host cells used were the cells from advanced animals like green monkey kidney cells, human cells, or egg cells. These cells are breeding well even after the exposure to acidic ozone water. Meanwhile, the microbe cells are killed very effectively by AOW. I believe that some kinds of antioxidant in the advanced cells may protect the cells from ozone attack. But the microbe cells without the antioxidant may be destroyed by the strong oxidation activity of ozone in AOW.”Uhm added that the AOW could be used in a variety of areas to avoid the spread of H1N1.“AOW may be abundantly available due to its easy preparation,” he said. “I am not an industrialist, but a scientist. I do not have any specific plan to make it available by myself, but some capable people may do. The AOW may be useful in hospitals, in livestock industries, in dairy farms, in seafood industries, or in agriculture. I initially studied the AOW for protection of mankind from an attack of bio weapons.”More information: Han S. Uhm, Kwang H. Lee, and Baik L.

(PhysOrg.com) — Scientists have found that acidic ozone water can deactivate H1N1 viruses very effectively, offering a promising disinfectant for the millions of people trying to avoid the disease. Acidic ozone water (AOW) is made from regular tap water mixed with a small amount of acid such as hydrochloric acid, along with an ozonized gas that can be produced in the lab. After deactivating the virus, the substance eventually decays into plain water, leaving no residue or harmful materials in the environment. Explore furtherlast_img read more

Shumway is also described as “an HTML5 technology experiment” that explores building an efficient renderer for the SWF file format without native code assistance. (The term SWF, a Flash file format, originally was used to abbreviate ShockWave Flash.)Using JavaScript to create the Flash virtual machine, it works in taking an SWF file and running it in a HTML5-compliant browser in a way that you no longer need the plug-in, and Flash developers continue to have their content run. The hope is that it will work well enough to enable a smooth transition where Flash development stays alive for a few more years if Flash fades as a standard browser plug-in.“Shumway is community-driven and supported by Mozilla,” says the project statement. “Integration with Firefox is a possibility if the experiment proves successful.” If Shumway does become part of Firefox, Mozilla will enjoy Flash compatibility as standard without having to collaborate with Adobe. Shumway is described as a “clean” solution in that it sidesteps any security issues in the Flash player; there is no Adobe code being run in order to render the content. Developers have had to put up with a series of reports and fixes of vulnerability exploits stemming from outdated versions of Adobe Flash Player. Flash is nonetheless pervasive; most online video content uses Flash, which continues to be a key part of browsing; the Web browser plug-in is still popular and is with all the grousing a principal addition for desktop browsing. As one tech site put it, a browser without Flash support in 2012 is a crippled browser. Microsoft has announced an “embedded”, not a plug-in, technically, of Adobe Flash Player in the Metro version of IE10 in Windows 8 and Windows RT.

If Shumway, still a work in progress, does prove to be a dependable way to translate SWF-based content on the fly, says the blogger, then it will be to Mozilla’s great credit. (Phys.org) — Mozilla’s experimental project on GitHub, a hosting service for development projects, is taking on a happy buzz where developers look at a future that may not include Adobe Flash. The project, called Shumway, is designed to try to interpret SWF (Flash files) using browser-standard technologies such as HTML5 and JavaScript. Said one anonymous Slashdot writer—reflecting general developer response– “All I can say is please and thank you!” The Shumway project replaces Flash player with a virtual machine. Those familiar with Shumway say that it is an open way to translate Flash content. More information: github.com/mozilla/shumwaylast_img read more

Experiment investigates how classical physics may emerge from quantum physics

first_img(Phys.org) —In order to better understand how the laws governing the quantum and classical regimes are related to one another, physicists have performed an experiment allowing them to observe a quantum-to-classical transition in a simple closed quantum system. The results suggest that classical behavior may be an innate property of certain isolated quantum systems such as the one studied here, and can emerge from quantum physics under certain conditions. (a) Illustration of a Bose-Einstein condensate exposed to a series of pulses from two incommensurate optical lattices that act as kicked rotors. (b) Diffraction spectra of atoms released after 1 kick and 40 kicks, when driven with a single lattice. The graph shows the momentum distribution after 40 kicks. (c) As in (b), but for driving with two lattices. The dashed black line in the graph at the bottom is a Gaussian profile corresponding to diffusive spreading, which signals classical behavior. Credit: Bryce Gadway, et al. ©2013 American Physical Society Although other demonstrations of quantum-to-classical transitions have been previously reported, the researchers explain that this demonstration is particularly interesting because it occurs in a closed system. More information: Bryce Gadway, et al. “Evidence for a Quantum-to-Classical Transition in a Pair of Coupled Quantum Rotors.” PRL 110, 190401 (2013). DOI: 10.1103/PhysRevLett.110.190401Professor Dominik Schneble’s webpage: Ultracold Physics at Stony Brook University “Thus far, most demonstrations of a quantum-to-classical transition have taken place in open quantum systems, where a purely quantum mechanical subsystem (such as a qubit) is coupled to some macroscopic reservoir, with the end result being decoherence of the pure subsystem,” Gadway said. “This is somewhat artificial because it relies on divorcing the reservoir from the system that decoheres; it assumes that information lost to the reservoir will never be returned. “What we’ve been able to show is that such quantum-to-classical transitions can emerge even in the dynamics of simple closed quantum systems. By coupling two quantum chaotic subsystems—so-called ‘kicked quantum rotors’—they both go from being localized due to destructive interference to displaying diffusive energy transport in a completely classical fashion. This is despite that the fact that all the dynamics are strictly unitary and time-reversible.”In the future, the physicists hope that the experiment can be extended to three or more coupled rotors using additional optical lattices. As Gadway explained, these experiments and others could provide further insight into the transition from localization to delocalization in nonlinear, disordered quantum systems.”One future line of investigation would be to simply scale this up to coupling three or more quantum kicked rotors, where we expect that the transition to classical behavior may happen for weaker driving and/or weaker rotor-rotor coupling,” he said. “We are also looking to couple the external motion of these particles to their internal states (i.e., their spin) to study quantum chaos in ‘spinful’ systems.” Illustration of the simple quantum system consisting of two incommensurate optical lattices that “kick” a macroscopic atomic matter wave (an optically trapped Bose-Einstein condensate).

The physicists, Bryce Gadway, et al., led by Professor Dominik Schneble at Stony Brook University in New York, have published their paper on the quantum-to-classical transition experiment in a recent issue of Physical Review Letters. Gadway is currently at the University of Colorado in Boulder.”Our results suggest that classical physics may emerge in a very natural way in large quantum systems—in this case, ‘large’ meaning just two coupled subsystems—without the invocation of an external ‘environment’ responsible for decoherence,” Gadway told Phys.org. “These results are certainly suggestive that classical behavior—specifically diffusive random-walk-like transport at the expected classical rate—is an innate property of this simple, quantum chaotic system.”The scientists’ observation confirms a prediction from 1988 by S. Adachi, et al., that classical behavior will emerge in a driven quantum system consisting of two coupled kicked rotors. In the new study, the researchers realized the kicked rotors by “kicking” a macroscopic atomic matter wave (an optically trapped Bose-Einstein condensate) with two periodically pulsed optical lattices. By spacing the pulses a certain way, the researchers could create coupling between the two optical lattices, which act as the rotors. The physicists found that the system’s momentum is affected differently when kicked by two coupled rotors compared with being kicked by a single rotor. Specifically, coupling causes a transition from localization to delocalization. In this context, localization means that the matter wave does not diffuse, or spread. On the other hand, delocalization corresponds to the emergence of classical diffusion, as well as fully chaotic behavior. Essentially, the coupling of the two kicked rotors results in a localization-to-delocalization transition, signaling a quantum-to-classical transition, just as predicted 25 years ago.

Study shows intense deep sea trawling leading to ocean floor desertification

first_img Journal information: Proceedings of the National Academy of Sciences Microscopic view of nematodes. Credit: Cristina Gambi, Marche Polytechnic University © 2014 Phys.org Explore further Over the past several decades, fish populations near shore have been severely reduced, forcing fishermen who wish to stay in business, to move farther out to sea. Those who catch fish using nets dragged along the seabed (trawling) now routinely trawl at depths up to 650 feet below the surface. Worse, they repeatedly trawl the same areas over and over until no more fish can be had, before moving on to a new spot. This, the researchers with the study, report, is not only reducing fish populations, but is also reducing the populations of all types of fauna that live on or near the seafloor.To better understand the impact of modern deep sea trawling, which includes repeated trawling over the same parts of the ocean, the researchers obtained sediment samples off the coast of Spain in areas known to be heavily trawled, with sediment samples taken from a sea canyon that had not been trawled and then compared the two for differences. They found that the heavily trawled area had 50 percent less biodiversity than the pristine area, which included 80 percent fewer sea worms. They also found that there was 52 percent less organic matter, and 32 percent slower carbon consumption. This they claim, suggests that daily carbon deposited onto the seafloor and removed by trawling may be as high as 60 to 100 percent, which of course, is unsustainable. The researchers liken it to the problem of soil erosion on lands that are over farmed.The researchers point out that their findings suggest that the continuation of intensive deep sea trawling represents a major threat to the biodiversity of the ocean sea floor and is likely to result in serious environment effects, one of which would presumably be a serious reduction in fish populations.

(2014) Chronic and intensive bottom trawling impairs deep-sea biodiversity and ecosystem functioning. Proceedings of the National Academy of Sciences, www.pnas.org/content/early/2014/05/14/1405454111AbstractBottom trawling has many impacts on marine ecosystems, including seafood stock impoverishment, benthos mortality, and sediment resuspension. Historical records of this fishing practice date back to the mid-1300s. Trawling became a widespread practice in the late 19th century, and it is now progressively expanding to greater depths, with the concerns about its sustainability that emerged during the first half of the 20th century now increasing. We show here that compared with untrawled areas, chronically trawled sediments along the continental slope of the north-western Mediterranean Sea are characterized by significant decreases in organic matter content (up to 52%), slower organic carbon turnover (ca. 37%), and reduced meiofauna abundance (80%), biodiversity (50%), and nematode species richness (25%). We estimate that the organic carbon removed daily by trawling in the region under scrutiny represents as much as 60–100% of the input flux. We anticipate that such an impact is causing the degradation of deep-sea sedimentary habitats and an infaunal depauperation. With deep-sea trawling currently conducted along most continental margins, we conclude that trawling represents a major threat to the deep seafloor ecosystem at the global scale.Press release A research team with members from Spain, Argentina and Italy has found that intense deep sea trawling cuts seafloor biodiversity in half. In their paper published in Proceedings of the National Academy of Sciences, the team reports on what they found in sediments taken from heavily trawled areas compared with seafloor areas that have not been trawled at all.

234 cattle genomes sequenced in Phase I of 1000 bull genomes project

first_img More information: Whole-genome sequencing of 234 bulls facilitates mapping of monogenic and complex traits in cattle, Nature Genetics (2014) DOI: 10.1038/ng.3034 . http://www.nature.com/ng/journal/vaop/ncurrent/full/ng.3034.htmlAbstractThe 1000 bull genomes project supports the goal of accelerating the rates of genetic gain in domestic cattle while at the same time considering animal health and welfare by providing the annotated sequence variants and genotypes of key ancestor bulls. In the first phase of the 1000 bull genomes project, we sequenced the whole genomes of 234 cattle to an average of 8.3-fold coverage. This sequencing includes data for 129 individuals from the global Holstein-Friesian population, 43 individuals from the Fleckvieh breed and 15 individuals from the Jersey breed. We identified a total of 28.3 million variants, with an average of 1.44 heterozygous sites per kilobase for each individual. We demonstrate the use of this database in identifying a recessive mutation underlying embryonic death and a dominant mutation underlying lethal chrondrodysplasia. We also performed genome-wide association studies for milk production and curly coat, using imputed sequence variants, and identified variants associated with these traits in cattle. Scientists take animal breeding to the next level (Phys.org) —A large team of researchers with members from Australia, France, Denmark, the U.S., Germany, Canada and the Netherlands, is reporting that 234 cattle have had their genomes sequenced as part of Phase I of the 1000 bull genomes project. In their paper published in the journal Nature Genetics, the researchers highlight the goals of the project, how it’s carried out and describe some of their initial findings.

The aim is to seek out and identify the genes responsible for both positive and negative attributes of both male and female cattle. The idea is to get ranchers and others with access to cattle to submit genetic samples for analysis, the results of which can be added to a single large database that will be made available to anyone interested in the results. In more specific terms, the goal is to reduce the number of cattle that have what are considered to be genetic defects to increase the percentage of healthy cattle that can be used in beef and dairy products production.In Phase 1 of the project, team members report that 234 (232 bulls and 2 cows) cattle have had their genomes sequenced—all from three breeds: Jersey, Fleckvieh and Holstein-Fresian. Each of the animals selected for inclusion in the project were prescreened—each needed to be representative of “key ancestors” which means they have the majority of the genetic variations for their breed.The team reports finding (among 28.3 million variants) genetic mutations responsible for conditions that lead to embryonic loss, curly fur and chondrodysplasia. Adding such information to a database can help beef and dairy product producers determine if newborn calves will grow to become viable and productive bulls or cows—culling those that are not increases revenue and profits.Eventually, millions of cattle from across the globe will be included in the project with the genome database growing larger and more productive along the way. Cattle raisers interested in joining the project must have at least 25 animals that are likely to be approved by the group’s steering committee.

Oppn has no organisational strength hence the allegations of violence

first_imgKolkata: Partha Chatterjee, secretary general of Trinamool Congress, said on Monday that the opposition leaders are making allegations of violence since they, as parties, do not have a strong organisational strength at the grassroot level.Chatterjee said in areas where the opposition parties have “some organisational strength”, they have fielded candidates there but in those where they are weak, the party leaders have alleged violence.Chatterjee said over the years, the Trinamool Congress has increased the organisational strength in the state. “There is not a single household in the rural areas that are not getting benefits from the various schemes taken up by the state government. Rs 2 a kilo rice has helped the rural populace immensely. Schemes like Kanyasree, Sikshasree, Sabuj Sathi, Rupasree have changed several lives forever. The rural populace has understood that to ensure development in their areas, there is no substitute for the Trinamool Congress,” he added.

But we did not give hope and continued to fight for the masses,” he said.Coming down heavily on BJP state president Dilip Ghosh, he said: “It is most unfortunate that Ghosh’s language is not only provocative but also unparliamentary. A few days ago, he had said on the day of polls, Trinamool workers and leaders will have to go back to their homes on stretchers. Such irresponsible statements are uncalled for. Instead of addressing a Press conference and making allegations, he should go to the villages and develop contacts with the people there and increase his organisational strength.” Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedChatterjee reiterated that the people of Bengal are the true strength of the Trinamool Congress and they will continue to support the party for its various developmental programmes.On Monday, the nomination process for elections to Bengal’s local bodies concluded with the ruling Trinamool Congress gaining control of a Zilla Parishad even before a single vote was cast.Panchayat elections in the state are scheduled to be held on May 1, 3 and 5 respectively.

Cylinder explodes wife of CRPF jawan dies

first_imgKolkata: The wife of a CRPF jawan died after a cylinder used for filling up gas balloons exploded during Raising Day celebration of the Central Force under New Township Police Station in Durgapur on Wednesday evening. A number of persons including some children were injured.Senior officers of CRPF visited the spot soon after the incident and also went to the hospital to take stock of the injured persons. CRPF personnel has filed a complaint with the New Township Police Station in Durgapur in connection with the incident. The balloon seller has been detained and the articles that he was using for inflating the balloons have been seized. According to police sources, the 50th Raising Day celebration was going on at the CRPF camp based in Durgapur. A fair was also held to commemorate the occasion. At that time, a cylinder that was being used for pumping helium gas in balloons exploded with a loud noise. More than 20 persons were injured, including some children. They were rushed to a local private hospital where Renu Singh(36), the wife of a CRPF jawan died. The doctors have, however, said the woman died of a heart attack that resulted due to her terrible fear when the cylinder exploded with a loud noise. A 15-year-old girl Sunita Kumari suffered serious injuries on her hand. She had an operation on Thursday morning. “We will conduct a probe to find out how the incident occurred. A police complaint has also been lodged,” a senior CRPF officer said. The balloon seller Subhash Chandra Majhi, a resident of Durgapur Township, has been detained by the police. Preliminary investigation has revealed that excess gas in the cylinder triggered the explosion.last_img read more
