The iron alloy even returns to its former shape when under almost twice the strain levels endured by current shape memory alloys. The alloy also exhibits changes in ductility and a large reversible change in magnetization during shape transitions. The alloy’s stress level is around double that of the shape memory alloy nickel-titanium, which means it can be formed into extremely thin wire. At present the nickel-titanium alloy is the only superelastic alloy available for practical use. Superelastic properties make a shape memory alloy ideal for delivering stents to parts of the body such as the heart since they can expand to a wider diameter when warmed by the body. Stents are tubes that are surgically implanted into blood vessels to prevent them collapsing. One of the engineers, T. Omori, said stents are currently delivered to the heart using nickel titanium wire, but its diameter is too thick to allow it to be used in the brain. The new iron alloy could be made thin enough to be used for brain stents.Omori said the elastic iron alloy may have other uses, such as in buildings in earthquake zones where a material that is both strong and flexible is needed. The buildings are deformed during the earthquake, but the iron alloy’s property of remembering and returning to its original form means the super-elastic alloy could return the building to its former shape. Other potential uses of superelastic alloys include blast protection, noise reduction, and vibration isolation.The paper was published in the journal Science last Friday.

Mpemba effect Why hot water can freeze faster than cold

first_img Freezing point of supercooled water varies with electric charge © 2010 PhysOrg.com Theories for the Mpemba effect have included:faster evaporation of hot water, which reduces the volume left to freeze formation of a frost layer on cold water, insulating it different concentrations of solutes such as carbon dioxide, which is driven off when the water is heatedThe problem is that the effect does not always appear, and cold water often freezes faster than hot water.Radiation safety officer with the State University of New York, James Brownridge, has been studying the effect in his spare time for the last decade, carrying out hundreds of experiments, and now says he has evidence that supercooling is involved. Brownridge said he found water usually supercools at 0°C and only begins freezing below this temperature. The freezing point is governed by impurities in the water that seed ice crystal formation. Impurities such as dust, bacteria, and dissolved salts all have a characteristic nucleation temperature, and when several are present the freezing point is determined by the one with the highest nucleation temperature.In his experiments, Brownridge took two water samples at the same temperature and placed them in a freezer. He found that one would usually freeze before the other, presumably because of a slightly different mix of impurities. He then removed the samples from the freezer, warmed one to room temperature and the other to 80°C and then froze them again. The results were that if the difference in freezing point was at least 5°C, the one with the highest freezing point always froze before the other if it was heated to 80°C and then re-frozen.Brownridge said the hot water cools faster because of the bigger difference in temperature between the water and the freezer, and this helps it reach its freezing point before the cold water reaches its natural freezing point, which is at least 5°C lower. He also said all the conditions must be controlled, such as the location of the samples in the freezer, and the type of container, which he said other researchers had not done.The effect now known as the Mpemba effect was first noted in the 4th century BC by Aristotle, and many scientists have noted the same phenomenon in the centuries since Aristotle’s time. It was dubbed the Mpemba effect in the 1960s when schoolboy Erasto Mpemba from Tanzania claimed in his science class that ice cream would freeze faster if it was heated first before being put in the freezer. The laughter ended only when a school inspector tried the experiment himself and vindicated him. Mpemba Effect.

FlyNano electric sea plane takes first test flight

first_img“When the FlyNano concept was presented last year at the Aero 2011 trade fair in Friedrichshafen, Germany, it was envisioned to be primarily powered with a combustion engine,” said the Finnish aeronautics firm by the same name, FlyNano.“ However, the development of electric motors and batteries has been immense during the past year and the demand for electric powerlines has been increasing continuously.”The cruising speed is around 140 km/h (87 miles per hour). The rudder is controlled by pedals. “Elevons” (ailerons + elevators) and throttle are controlled intuitively by a stick with the right hand. The designers say their electric sea plane is quiet, and power-train vibration is reduced.FlyNano’s goal is to start production and deliver the first 35 planes to dealers by the end of 2013. The FlyNano plane has an ex-factory price listed on the company site as 32,000 euro ($40,000). Transport and storage trailer charges are extra.A promotional portion of text on the site tells prospective customers that, “If you’ve ever had a pilot’s licence you’ll fly Nano right out of the box.” For the rest, knowledge of simple rules of the air will be required, says the team. The FlyNano FAQ page, however, directly answers the question of whether customers need a pilot’s license to fly the plane. According to the European Aviation Safety Association regulation. FlyNano is below the necessary weight of 70kg, which means that national authorities decide on the classification. “Nevertheless a good understanding of water plane operation, rules and aviation safety is requested.” The company adds that “We will clear the situation in several countries around the world within the following months.”FlyNano does not have a windshield, but in keeping with the company’s philosophy of “feel the wind,” the recommended gear includes helmet or at least goggles and drysuit/wetsuit or similar clothing. FlyNano has stated that due to advances in batteries and electric motors, they ditched combustion models. The carbon fiber-bodied aircraft is now electric. Citation: FlyNano electric sea plane takes first test flight (2012, June 18) retrieved 18 August 2019 from https://phys.org/news/2012-06-flynano-electric-sea-plane-flight.html The 70 kilo single person plane (Phys.org) — A single-seat carbon-fiber airplane designed for water operations and proposed as a “fun flyer” has taken its first test flight at Finland’s Lake Hepari. The June test flight comes after more than a year since its introduction at an air show in Germany in 2011. The earlier FlyNano was showcased as a single-occupant petrol/electric microlight amphibious aircraft. The new FlyNano has undergone key changes to advance its readiness for takeoff. Gone are the petrol-engine models. The new engine, propeller, controller and batteries combine to produce a stronger model than the earlier structure. center_img This document is subject to copyright.

Physics team suggests possible way to make quantum cryptography available in handheld

first_img Being able to encrypt data and the key that allows for unlocking it has become important in modern life. Companies spend millions attempting to protect sensitive information while hackers work non-stop trying to overcome such hurdles to access that information. The current system (RSA) is believed to be, at least for now, just ahead of the hackers. It relies on public key encryption of plain text and privately encrypted keys. This system has two weak points. The first is that it assumes that a hacker has not been able to gain access to a private key through nonconventional means and the second is that it’s based on mathematical algorithms that can be cracked given fast enough computers. To gain the upper hand, cryptologists have turned to quantum key distribution (QKD), where quantum bits are used to represent private keys. The main advantage here is that according to the laws of physics, it should be impossible for a hacker to use the key without their interception being detected, which would prevent the sensitive data from being sent.Up till now, the main hindrance to using QKD has been that it requires a lot of heavy duty equipment and a straight line mode of transport between the sender and receiver due to its sensitivity to noise. In their paper, the team from Bristol claim to have come up with a scheme that should allow a way to overcome such restrictions, at least on the receiver side. It’s based on what they call a reference frame independent QKD protocol for polarization of qubits in polarization maintaining fiber—which in essence means they use math (based on measurements made in random directions) to describe a way for moving photons through fiber cables without disturbing their polarizationThe team has not yet built such a device of course, that will need to be done by applied physicists, engineers and computer professionals—thus it’s not yet a certainty that such a device will work as imagined. One sticking point in particular might be whether the real-world system is actually able to overcome the inherent noise sensitivity. (Phys.org) —A team of physicists at Bristol University in the U.K. has proposed a possible way to allow for quantum cryptography between a large station and a small hand held device. They describe such a technique in a paper they have uploaded to the preprint server arXiv. © 2013 Phys.org Experimental set-up for client-server rfiQKD. The server side holds a telecom wavelength (1550 nm) laser with a 1 MHz pulse generator (PG) and fixed polariser, to send light pulses to the client through a polarisation maintaining fibre (PMF). At the client side, an integrated polarisation controller (PC) encodes qubits into the polarisation of the attenuated (Att.) light. A fibre beam splitter (FBS) and photodetector (PD) continuously monitor power for malicious attacks. Qubits received back at the server side are measured with a similar PC, fibre polarising beamsplitter (FPBS), and superconducting single photon detectors (SSPDs), all controlled by an electronic board synchronisation (Sync.), function programmable gate array (FPGA), and processor. The Bloch sphere illustrates the effects of an unstable environment on polarisation.

Scientists uncover universal features of first passage under restart

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Sample applications of first passage under restart: (Top) During a search and rescue mission, a team of searchers might need to temporarily stop searching, return to base, and start again. (Middle) A computer algorithm performing a random search may start down the wrong path, but programmed restart could give it a second chance. (Bottom) A molecule prepared in an excited state may decay to a low-energy state without forming a desired product, but the molecule could be excited again by a laser pulse. This time, a different chemical reaction could occur in which the desired product is formed. Credit: Pal et al. ©2017 American Physical Society While first passage under restart has been used to describe a wide variety of processes, part of the problem with this variety is that currently there is no general, unifying approach that could be applied regardless of the particular details of the process or restart mechanism.By developing a general framework for first passage processes under restart, Pal and Reuveni have addressed this problem. Using this framework, they then identified an optimal strategy, called sharp restart, that outperforms all possible restart strategies in terms of attaining the shortest average first passage time. As the researchers explain, sharp restart is very simple in essence: simply stop the process and start it anew after some fixed amount of time, with the exact amount of time depending on the problem. The results have a wide variety of potential applications.”In foraging theory, one studies the movement of animals searching for food, mates and shelter in the wild, and it’s quite fascinating to see how animals try to optimize their foraging activities,” Pal said. “First passage under restart can then be used as an idealized description for some of these activities. One possible, yet unexplored, direction in which this could be taken is the study of prehistoric migration patterns of human groups searching for new and more accommodating territories. “Another application is in the development of more efficient search strategies that may aid in finding lost objects, or help construct rescue operations for crashed airplanes or lost submarines. Search processes also naturally appear in the context of biochemical reactions when one molecule searches for a reactive target site, and first passage under restart could also be used to describe enzymatic reactions.”Currently, one drawback of the sharp restart strategy is that it may be hard to implement using molecules due to the high energetic cost. In the future, the researchers plan to further analyze this problem to come up with nearly optimal restart strategies that perform almost as well but consume less energy. These strategies could become especially important in living cells or in man-made molecular devices.”Restart is routinely used to expedite the completion of randomized computer algorithms, but its importance in physical, chemical, and biological processes is just starting to be realized,” Pal said. “We intend to explore restart in these contexts and are particularly interested to find out if biological systems have found a way to also take advantage of restart and the benefits it can offer.” © 2017 Phys.org Journal information: Physical Review Letters (Phys.org)—Discovering the ways in which many seemingly diverse phenomena are related is one of the overarching goals of scientific inquiry, since universality often allows an insight in one area to be extended to many other areas. Citation: Scientists uncover universal features of ‘first passage under restart’ (2017, February 1) retrieved 18 August 2019 from https://phys.org/news/2017-02-scientists-uncover-universal-features-passage.html Working along these lines, researchers in a new study have developed a general framework for the “first passage under restart” model, which describes a wide range of statistical phenomena in physics, chemistry, biology, finance, and other fields. By identifying an optimal strategy and showing that it cannot be outperformed by any other strategy, the researchers have taken steps toward improving the performance of many diverse processes with a wide range of applications, such as efficient computer coding, biochemical reactions in cells, and wildlife foraging.The researchers, Arnab Pal at Technion-Israel Institute of Technology and Shlomi Reuveni at Harvard Medical School, have published a paper on their development of a general theoretical framework for first passage under restart in a recent issue of Physical Review Letters.”We have developed a theoretical framework for first passage under restart,” Pal told Phys.org. “The framework is extremely general and offers applications to a wide and diverse class of problems in computer science, computational physics, biophysics, non-equilibrium statistical physics, and more.”First passage under restart is a variation of the “first passage time” framework, which was originally developed in the context of non-equilibrium systems and used, for instance, to study the time it takes for a particle with random motion to reach a certain location. More generally, the first passage time is the time taken for any random variable to reach a certain threshold value. It is especially useful for accounting for the inherently probabilistic nature of statistical processes, such as neuron firing, fluorescence quenching, or stock market activity.More recently, researchers have investigated what happens when a process is stopped and started again from its initial starting point. Studies have shown that restart can have advantages for certain problems that “get off to a bad start”—for example, a search algorithm that randomly scans for a solution to a problem, but starts off searching along a path that goes in the wrong direction. Restart could then help rescue a futile search by starting it anew. More generally, restart could help in a situation when it is unclear if the process will end quickly or only after a long period of time.

Tallness in Herzegovinian men linked to gene passed down from ancient big

first_img(Phys.org)—A team of researchers with members from Montenegro, the Czech Republic and Croatia has found a possible genetic link between early big-game hunters of the Upper Paleolithic Gravettian culture and modern Herzegovinian men. In their paper published in the journal Royal Society Open Science, the group describes how they surveyed a large number of Bosnian and Herzegovinian men and compared what they found with a gene believed to be at least partly responsible for causing people to grow taller than average. More information: Pavel Grasgruber et al. The mountains of giants: an anthropometric survey of male youths in Bosnia and Herzegovina, Royal Society Open Science (2017). DOI: 10.1098/rsos.161054AbstractThe aim of this anthropometric survey, conducted between 2015 and 2016 in Bosnia and Herzegovina (BiH), was to map local geographical differences in male stature and some other anthropometric characteristics (sitting height, arm span). In addition, to investigate the main environmental factors influencing physical growth, the documented values of height would be compared with available nutritional and socioeconomic statistics. Anthropometric data were collected in 3192 boys aged approximately 18.3 years (17–20 years), from 97 schools in 37 towns. When corrected for population size in the examined regions, the average height of young males in BiH is 181.2 cm (181.4 cm in the Bosniak-Croat Federation, 180.9 cm in Republika Srpska). The regional variation is considerable—from 179.7 cm in the region of Doboj to 184.5 cm in the region of Trebinje. These results fill a long-term gap in the anthropological research of the Western Balkans and confirm older reports that the population of the Dinaric Alps is distinguished by extraordinary physical stature. Together with the Dutch, Montenegrins and Dalmatians, men from Herzegovina (183.4 cm) can be regarded as the tallest in the world. Because both nutritional standards and socioeconomic conditions are still deeply suboptimal, the most likely explanation of this exceptional height lies in specific genetic factors associated with the spread of Y haplogroup I-M170. The genetic potential for height in this region could then be the greatest in the world. Future studies should further elucidate the roots of this intriguing phenomenon, which touches an important aspect of human biodiversity. Human chromosomes during metaphase.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. It has been noted that men from Herzegovina are taller on average than men in other places—the average male height is just over six feet. But why the men there are so tall has been a mystery, especially considering the relative poverty of the area for very long periods of time. The region, in the Dinaric Alps, actually boasts the tallest average male height, though the Netherlands, a country that has enjoyed a high standard of living and thus a strong diet for a very long time, holds the record for tallest average for an entire nation. To understand why men in Herzegovina are so tall, the researchers started by looking at the I-M170 chromosome, which prior research has shown is highly prevalent in Herzegovinian people—approximately 70 percent have it.The new research entailed surveying 3,207 Herzegovinian men between the ages of 17 and 20 regarding details on height and other body measurements—they found the average male height to be 181.2 cm. They then noted that prior research has shown that people of the Gravettian culture were exceptionally tall, as well, many of them averaging over six feet. They also noted that people in Herzegovina tend to ingest more calcium than people elsewhere due to minerals in the limestone bedrock in the area making their way into food sources. Putting all the data together, the researchers concluded that the most likely cause of larger-than-average height of Herzegovinian men is lifestyle during the Paleolithic—men hunted large animals such as mammoth for survival—such a diet, heavy in protein, combined with small population densities, would have provided ideal conditions for height selection, resulting in increasingly taller men who passed the trait down through their I-M170 chromosome to future generations.

Central govt employees complain of language barrier over Panchayat election duty

first_imgKolkata: With notices having started reaching different Central government offices for engaging its employees to conduct the forthcoming Panchayat polls, the issue of “language-barrier” has started cropping up, with most employees having a “non-Bengali” background.According to the sources in the State Election Commission (SEC), directives have been given to engage Central government employees to conduct the Panchayat polls. The Central government employees of all ranks would be required to get involved in the election process, apart from the state government employees. Also Read – Heavy rain hits traffic, flightsThe issue related to the “language barrier” has cropped up as most officials in the Central government offices are from non-Bengali backgrounds and hence, they would face trouble in communicating properly with people in the grassroot level, in the rural parts of the state.In a bid to conduct the Panchayat polls, the officials need to visit different villages of the state, where they would have no other option apart from speaking in the local language. Communicating in local language will also be essential to make the people from the area understand what they actually have to convey.

Accordingly, orders have been issued in this connection as usual and there is no such exemption in the set norms for the Central government employees. The district magistrates play a major role in preparing the list of the manpower needed to conduct the polls. The SEC has held meetings with district magistrates and superintendents of police of all the districts in March, in connection with the Panchayat polls.It may be mentioned that the elections will be held on May 1, 3 and 5. The process of filing nomination has already started from April 2 and it will continue till April 9. The last date of withdrawal of candidature is April 16. The districts where the election will be held in the first phase, include all the South Bengal districts, apart from Murshidabad and Birbhum. Polls in these two districts will be held on May 3, while the same in the North Bengal districts, starting from Malda to Cooch Behar, will be held on May 5.last_img read more

153yrold Shipwreck Successfully Removed Remarkably Intact

first_imgIt took five days — and it reportedly cost more than $1 million — to remove a 153-year-old shipwreck from a beach in West Auckland, New Zealand, but miraculously it was lifted almost fully intact. The 55-foot schooner Daring was driven ashore by gale force winds in March 1865. It was uncovered by the shifting sands at Muriwai Beach in May 2018, and removed by the “Daring Rescue Team” in mid-December.Photo by Daring Rescue Team“The shipwreck is a significant find, and provides archaeologists with a rare opportunity to record and gather information toward analysis of colonial ship construction and adaptations. The Daring is a great example of this,” says Heritage New Zealand’s Mid Northern Manager, Bev Parslow.Larry Paul, from the Classic Yacht Charitable Trust, told media that volunteers slept on the beach between tides as the ship was excavated.“It’s a beautiful piece of work,” Paul said. “The Daring was made in an earlier era of boat building, and it is the only kind probably in the world that is still fully intact.”Photo by Daring Rescue TeamA shoe, coins, a cup, clay pipes, and multiple wine bottle caps dating to the 19th century were found on the ship.The Daring belonged to Onehunga storekeeper David Kirkwood, according to Recon, commissioned by Heritage New Zealand to laser scan the ship.In its 18 months of service it proved to be a solid, reliable “workhorse,” said Recon. Its final journey was transporting a cargo of grass seed from Taranaki up to the Manukau.Paul said it took months of paperwork to get the necessary approvals to remove it. On December 10th, the removal of the Daring from the sand began when artifacts were taken out of the vessel.Photo by Daring Rescue TeamThe next day, two big excavators on each side of the vessel managed to wiggle out sand from inside the ship.On day three, the Daring was successfully lifted from the sand and placed above the water level mark.“It was a huge challenge, mainly because we had to get it ready and work with the tide,” Paul said. “We had four hours to work on each day and some of the crew slept on the beach waiting for the tides.”Photo by Daring Rescue TeamThe Daring was moved 25 miles (40 kilometres) across Muriwai Beach with a big loader truck.“It took 45 minutes to move it to hard sand, and another two and half hours more after that using road track maps,” he said in the interview with Stuff.Recon reported the events that sent the ship to its resting place of more than 100 years. “Things were going to plan but as the Daring hove off the entrance to the Manukau a strong south-west gale developed and blew the ship off course until the crew found themselves off the Kaipara,” says Parslow.Photo by Daring Rescue TeamDespite all their efforts, Captain Phipps – who was at the helm of the Daring – realized that the ship was being driven onto land. With no chart of the Kaipara on board, Phipps decided to put the ship ashore in as controlled a manner as they could by dropping the anchor just prior to the ship striking the sand in order to ease its landing.Phipps’ decision saved his own life, the lives of his crew, the ship and its cargo.Photo by Daring Rescue Team“The Daring was undamaged, and the crew escaped safely and sheltered on the beach,” said Parslow. “Phipps, two passengers and a seaman set off for Onehunga the next day to get help.”After the ship re-emerged in May 2018, it attracted media attention. Unfortunately, part of the wreck was damaged by scavengers – “one of whom used a chainsaw to cut part of the structure off and take it away.” One of the reasons for the aggressive plan for removal was to protect it from more criminal acts.After being excavated, the Daring was taken to the edge of Muriwai forest and hosed down by the Muriwai Volunteer Fire Brigade.Read another story from us:  Barbra Streisand and Elvis Presley Almost Starred and Sang TogetherIt was then moved to a location in Hobsonville, where it will remain until plans for its preservation and final destination were finalized.last_img read more
