Achieving optimal efficiencies for nanoengines

first_img(PhysOrg.com) — “There’s a lot of recent interest in understanding the functioning and optimal performance of small systems,” Katja Lindenberg tells PhysOrg.com. Lindenberg is a scientist in the Department of Chemistry and Biochemistry and the Institute for Nonlinear Science at the University of California, San Diego, in La Jolla. Along with Massimiliano Esposito, also at the Institute, and Christian Van den Broeck at Hasselt University in Diepenbeek, Belgium, Lindenberg has been studying the efficiency of very small thermochemical engines. “Thermodynamics applied to small systems is different from what we are used to,” Lindenberg continues. “It’s a relatively new field, and we are trying to understand optimal performance criteria.” The results of an investigation by Lindenberg, Esposito and Van den Broeck into power generation by small thermochemical engines is presented in Physical Review Letters: “Universality of Efficiency at Maximum Power.”Lindenberg explains that “maximum efficiency is achieved only near equilibrium, where the power output is very small. Instead of focusing on maximum efficiency alone, we are studying how to achieve maximum possible efficiency at maximum power.”Esposito says that in order to explore the general rules that govern performance at maximum power, a general single framework is needed – one that can encompass many systems that on the surface appear very different from one another. “The systems of interest all produce a workflow, or power, fueled by a heat flow through the system generated by a temperature gradient,” he says. “Optimal efficiency at maximum power is obtained when the heat and work fluxes are strongly coupled. For instance, if the workflow is a flow of particles against a chemical potential gradient, strong coupling occurs when the only carriers of heat are the same particles.” “This strong coupling between the work and heat flows is a natural feature of small systems — nanosystems,” Esposito continues, “but would be difficult or impossible to achieve in a macroscopic system.” The team has illustrated this concept in a paper appearing in Europhysics Letters, in which they consider electrons flowing through a quantum dot.Both Lindenberg and Esposito emphasize that, so far, their work is purely theoretical and only illustrated in model systems. “It might be difficult to build a device that satisfies the conditions we have set out,” Lindenberg admits, “but on a fundamental level it gives a conceptual basis for what is possible. It provides an idea of what the ultimate goal would be when it comes time to design a device.”What sort of devices might be possible? Like many theorists, Esposito and Lindenberg hesitate to prognosticate. However, Esposito mentions at least one idea regarding the use of thermochemical engines: “Perhaps a device could be created to recover the energy from heat loss in a car’s engine.”For now, though, work moves forward in trying to understand small systems and their properties. “With continued interest in the smallest of systems,” Esposito points out, “it is increasingly important to learn how one can use extremely small systems to achieve optimal efficiencies at maximum power.”More information: Esposito, Lindenberg and Van den Broeck, “Universality of Efficiency at Maximum Power.” Physical Review Letters (2009).

National security expert warns of Asian space race

National security expert warns of Asian space race

first_img More information: Technology: Asia’s space race, Nature 480, 171–173 (08 December 2011) doi:10.1038/480171a Journal information: Nature China Xichang Satellite Center; The launch of Tianlian I-01 satellite (a Data Relay & Tracking Satellite); The newly developed Long March 3C Carrier Rocket. Image: Wikipedia. Explore further Moltz writes that despite denials by the major Asian players, there exists the beginnings of a space race among the most technologically advanced countries in the area. In the lead of course is China, which besides the United States and Russia, is the only country to have put a person in space on its own. Other Asian countries actively involved in space technology include India, South Korea and Japan, though others such as Vietnam, Indonesia, Malaysia, Thailand and Taiwan are working on building a presence as well.Japan of course, has been actively involved with the International Space station, and India has been putting nerves on edge by mixing its space technology with military goals by building rockets capable of carrying a payload all the way to Beijing. The country has also launched its own rockets into space to deliver satellites, though it’s not yet achieved the broad range of successes of the Chinese program.The problem with an Asian space race, Moltz contends, is that it builds an arena of unhealthy competition bred out of historic geopolitical rivalries. It also wastes resources, but that’s not something that should concern other countries. What should he writes, is the possibility of an Asian space race morphing into an Asian arms race, something that could impact virtually every nation on Earth.The current situation, he explains, is a collection of Asian countries who are unwilling to work together to meet mutual goals such as can be seen with the European Space Agency (ESA). Instead, individual countries work independently, quite often duplicating work done by other countries both in Asia and in the west, resulting in secretive programs that have as a goal beating one another to the next level, rather than building programs that serve the national, or international good.What is perhaps most chilling about an Asian space race is the way China, which is the clear leader, has gone about its space program, highlighted not by its triumphs in manned exploration, but in it’s destruction of one of its dead weather satellites by an anti-satellite weapon back in 2007. Not only did that action contribute to the vast collection of space junk, but it sent shock waves through the entire international community as it demonstrated very clearly the types of technology China has been secretly working on. And because of its leadership role in the Asian community, the action has likely set other countries to develop their own such weapons.One other worrisome offshoot of the space race is the impact it might have on those Asian countries unable to join in. Pakistan, for example, a country with nuclear weapons, has voiced concerns over the missile technology that India has developed and has repeatedly made it clear that any actions by India it deems a threat to its own survival would be met with all out war, including the use of nuclear bombs. (PhysOrg.com) — James Clay Moltz, an associate professor in the department of national security affairs at the Naval Postgraduate School in Monterey, California, has published a commentary paper in the journal Nature where he warns of a possible space race involving many Asian nations, possibly leading to an arms race.center_img This document is subject to copyright.

In their paper published in the journal Physical Review Fluids, the group describes the factors they took into consideration in developing their model and how well it worked in experiments conducted with pig blood and sponges. Explore further More information: P. M. Comiskey et al. Prediction of blood back spatter from a gunshot in bloodstain pattern analysis, Physical Review Fluids (2016). DOI: 10.1103/PhysRevFluids.1.043201ABSTRACTA theoretical model for predicting and interpreting blood-spatter patterns resulting from a gunshot wound is proposed. The physical process generating a backward spatter of blood is linked to the Rayleigh-Taylor instability of blood accelerated toward the surrounding air, allowing the determination of the initial distribution of drop sizes and velocities. Then the motion of many drops in air is considered with governing equations accounting for gravity and air drag. Based on these equations, a numerical solution is obtained. It predicts the atomization process, the trajectories of the back-spatter drops of blood from the wound to the ground, the impact angle, and the impact Weber number on the ground, as well as the distribution and location of bloodstains and their shape and sizes. A parametric study is undertaken to predict patterns of backward blood spatter under realistic conditions corresponding to the experiments conducted in the present work. The results of the model are compared to the experimental data on back spatter generated by a gunshot impacting a blood-impregnated sponge. When a person is shot dead and there are no witnesses, forensic investigators attempt to use every bit of evidence they can find at a crime scene to figure out what happened; one source is blood spatter that occurs when a victim’s blood is sent flying against walls or onto the floor as a bullet enters the body and then again as it exits. In this new effort, the researchers have developed a model to help better describe spattering events which could lead to a more accurate depiction of a crime scene.Up till now, forensic experts have used three basic types of spatter results to assist in identifying the type of bullet wound that caused it: high, medium and low velocity. Using such categories helps to identify the type of weapon used to propel the bullet. But this approach, the researchers claim, fails to take into account other factors such as gravity and air resistance which can cause blood to follow an arc as it falls. To correct that problem, the researchers built theoretical models meant to describe what happens when a dense liquid such as blood runs directly into a gas such as air. They also factored in the mass of the bullet, its speed and its angle as it strikes the body. The result was a mode that describes a resulting “blood cloud” for a given set of circumstances.To test their model, the researchers soaked sponges in pig blood and shot them, taking measurements of the blood spatters that resulted. They report that their results were mixed, though they were within an order of magnitude of predictions. They plan to run more experiments using different types of guns and bullets to make their model progressively better. They believe that at some point the model will be good enough for use with real crime scenes.

I had come to Bhadreshwar following the death of Bikhari Paswan, a worker of Kanoria Jute Mill. I have seen how CPI(M) had unleashed a ‘Reign of Terror’ in different areas in Hooghly and Howrah. The anti-social elements of CPI(M) have now joined the BJP,” she maintained. At the Amdanga rally, without naming Arjun Singh, the BJP candidate from Barrackpore Lok Sabha seat, Banerjee said: “Do not to cast a single vote to the gaddar (traitor). Vote for the Trinamool candidates as they are secular and the party will play a major role in the formation of the new government in Delhi.” In Amdanga, TMC’s Dinesh Trivedi took a lead of 83,233 votes from here in 2014 Lok Sabha elections. Banerjee urged the people to ensure that the lead of Trivedi goes up from the segment. She cautioned the people against BJP and RSS workers who would try to buy their votes. “Don’t take money from them and inform the police if they try to buy your votes,” she said. The election in Barrackpore Lok Sabha seat will be held on May 6.last_img read more

Cheat day during keto diet damages blood vessels

Cheat day during keto diet damages blood vessels

first_imgHaving just a plate of fries or a bottle of soda while following a ‘keto diet’ may damage your blood vessels, say scientists who warn against going for a ‘cheat day’ while following the popular weight loss regime. The ketogenic or keto diet has become very common for weight loss or to manage diseases like type 2 diabetes. “It consists of eating foods rich in fats, moderate in protein, but very low in carbohydrates and it causes the body to go into a state called ketosis,” said Jonathan Little, associate professor at University of British Columbia (UBC) in Canada. Also Read – Add new books to your shelfThe diet can be very effective because once the body is in ketosis and starved for its preferred fuel glucose, the body’s chemistry changes and it begins to aggressively burn its fat stores, Little said in a statement. This leads to weight loss and can reverse the symptoms of diseases like Type 2 diabetes. The often embraced ‘cheat day’ is a common theme in many diets. However, researchers found just one 75-gramme dose of glucose – the equivalent a large bottle of soda or a plate of fries – while on a high fat, low carbohydrate diet can lead to damaged blood vessels. Also Read – Over 2 hours screen time daily will make your kids impulsive”We were interested in finding out what happens to the body’s physiology once a dose of glucose is reintroduced,” said Cody Durrer, doctoral student at UBC. “Since impaired glucose tolerance and spikes in blood sugar levels are known to be associated with an increased risk in cardiovascular disease, it made sense to look at what was happening in the blood vessels after a sugar hit,” said Durrer. For their test, the researchers recruited nine healthy young males and had them consume a 75-gramme glucose drink before and after a seven-day high fat, low carbohydrate diet. The diet consisted of 70 per cent fat, 10 per cent carbohydrates and 20 per cent protein, similar to that of a modern ketogenic diet. “We were originally looking for things like an inflammatory response or reduced tolerance to blood glucose. What we found instead were biomarkers in the blood suggesting that vessel walls were being damaged by the sudden spike in glucose,” said Durrer. The most likely culprit for the damage is the body’s own metabolic response to excess blood sugar, which causes blood vessel cells to shed and possibly die. “Even though these were otherwise healthy young males, when we looked at their blood vessel health after consuming the glucose drink, the results looked like they might have come from someone with poor cardiovascular health,” said Little. The researchers point out that with only nine individuals included in the study, more work is needed to verify their findings, but that the results should give those on a keto diet pause when considering a cheat day. “My concern is that many of the people going on a keto diet – whether it’s to lose weight, to treat Type 2 diabetes, or some other health reason – may be undoing some of the positive impacts on their blood vessels if they suddenly blast them with glucose,” Little said. “Especially if these people are at a higher risk for cardiovascular disease in the first place. Our data suggests a ketogenic diet is not something you do for six days a week and take Saturday off,” he added.last_img read more

Exim Bazaar makes its way to Kolkata

Exim Bazaar makes its way to Kolkata

first_imgThe fourth edition of Exim Bazaar, an exhibition that showcases specially curated ethnic products handmade by craftspeople across rural India, opened in Kolkata recently. Debasish Mallick, Deputy Managing Director, Export-Import Bank of India (Exim Bank) while inaugurating the exhibition said, “Handicrafts and handloom products are a manifestation of the roots, culture and identity of the people and perhaps the richest creative traditions of any country.” Also Read – Add new books to your shelfMallick conveyed that every handicraft item holds stories myths and faiths transferred through generations of craftspeople or through people related to this field. The exhibition-cum-sale will be on until April 14, 2019, between 10:00 am and 8:00 pm at the Ice Skating Rink, Kolkata. Exim Bank, through its Grassroots Initiatives programme has been supporting artisans, master craftsmen, weavers, grassroots and micro enterprises, in their capacity-building programs and in helping them secure access to institutional finance and technology, aimed at promoting operational efficiency, achieving higher value addition and enhanced market reach. Also Read – Over 2 hours screen time daily will make your kids impulsiveOne of the innovative activities initiated by Exim Bank in its continuing market outreach effort is the Exim Bazaar. First launched in September 2017, Exim Bazaar is a unique platform for artisans who have been supported by bank in the past through workshops, finance, training programmes, exhibitions and trade fairs. The bank has already conducted three editions of Exim Bazaar in Mumbai and Ahmedabad and the response generated a great deal of interest in the artisanal community. “Encouraged by the response of the earlier editions of Exim bazaar, the bank decided upon extending its reach to Kolkata. It is in this context that we are here today inaugurating the fourth edition of Exim Bazaar in Kolkata coinciding with the onset of the Bengali New Year,” said Mallick. ” Typically, the rural artisans face high physical and transaction costs in accessing distant markets. They are also constrained by lack of information about markets, business skills and collective organisation that can interact with large market intermediaries. This platform is a part of Exim Bank’s endeavour to make a difference to the livelihoods of those participating, by affording a vibrant market in this part of the country,” he added.last_img read more

Just 16minute sleep loss may put your job at risk

Just 16minute sleep loss may put your job at risk

first_imgLosing just 16 minutes of sleep could be the difference between a clear-headed day at the office or one filled with distractions, say scientists. A study found that reducing your sleep routine during the work-week greatly interferes with job performance. The researchers found workers are more likely to have poor judgement and fall off-task the next day. Researchers surveyed 130 healthy employees who work in IT and have at least one school-aged child. Also Read – Add new books to your shelfParticipants reported that when they slept 16 minutes less than usual and had worse quality sleep, they experienced more cognitive issues the next day. That raised their stress levels, especially regarding issues related to work-life balance, resulting in them going to bed earlier and waking up earlier due to fatigue. “These cyclical associations reflect that employees’ sleep is vulnerable to daily cognitive stress and also a contributor to cognitively stressful experiences,” said Soomi Lee, assistant professor at University of South Florida. Also Read – Over 2 hours screen time daily will make your kids impulsive”Findings from this study provide empirical evidence for why workplaces need to make more efforts to promote their employees’ sleep. Good sleepers may be better performers at work due to greater ability to stay focused an on-task with fewer errors and interpersonal conflicts.” Researchers also compared work-days to weekends. They conclude the consequences of less sleep is not as apparent when one has the next day off.last_img read more

Severe air pollution may cause birth defects deaths

Severe air pollution may cause birth defects deaths

first_imgHarmful particulate matter in the atmosphere may lead to birth defects and even fatalities during pregnancy, according to a study conducted in mice. Researchers at Texas A&M University in the US examined the adverse health effects of exposure to fine particulate matter consisting of ammonium sulphate commonly found in many locations around the world. During winter months in India and China, where severe haze events frequently occur, fine particulate matter levels are especially high at several hundred microgrammes per cubic metre, they said. Also Read – Add new books to your shelfAccording to the World Health Organization (WHO), nine out of 10 people worldwide breathe air containing high level of pollutants. One out of every nine global deaths can be attributed to exposure to air pollution, totalling over seven million premature deaths a year, researchers said. “People typically believe that ammonium sulphate may not be terribly toxic, but our results show large impacts on female pregnant rats,” said Renyi Zhang, a professor at Texas A&M University. Also Read – Over 2 hours screen time daily will make your kids impulsive”It is unclear yet what is causing these profound effects, but we speculate that the size of nanoparticles or even the acidity may be the culprit,” Zhang said. Sulphate is mainly produced from coal burning, which is a major energy source for much of the world in both developed and developing countries. Ammonium is derived from ammonia, which is produced from agricultural, automobile, and animal emissions, “so this certainly represents a major problem worldwide,” Zhang said. “However, our results show that prenatal exposure to air pollution may not dispose offspring to obesity in adulthood,” said Guoyao Wu, Texas A&M University Distinguished Professor and one of the lead authors of the study. “Nutrition and lifestyle are likely major factors contributing to the current obesity epidemic worldwide,” Wu said. Numerous previous studies have shown that air pollution is a serious public health threat throughout the world, with millions of people breathing air that is far less than standards set by the WHO. Previous studies have shown such pollution to impair metabolic and immune systems in animal offspring. However, the study shows definitive proof of decreased foetal survival rates, and also shortened gestation rates that can result in smaller body weight, in addition to damage to brains, hearts and other organs in the adult rat models. The findings present obvious concerns and challenges on a multi-scale level, the researchers said. “While epidemiological studies have been widely adopted to assess the health effects of air pollution, these tend to yield little insight into adverse outcomes and long-term effects,” Zhang said. “Furthermore, there is an absence of clinical recommendations for prevention and treatment of air pollution-related health issues. “Our study has demonstrated that well-controlled exposure experiments using animal models offer major advantages for future air pollution control and are promising in the development of therapeutic intervention and treatment procedures,” he said.last_img read more
