Cyclists Beware of Wind Noise

first_img Cyclists Ever think about how all the wind rushing past your ears could be slowly damaging your hearing? For Michael Seidman, MD, otolaryngologist and head and neck surgeon at Florida Hospital, the answer is yes. It occurred to him recently when he was out biking with his brother.“We were riding 18 to 20 mph and we couldn’t hear each other speak,” Dr. Seidman says. “I knew this had to be bad for hearing; I’ve determined that wind noise at speeds higher than 10 mph creates enough sound to damage the ear.”Michael Seidman, MD“People don’t think about it,” he adds. “We know about motorcyclists and wind noise when the rider doesn’t wear a helmet, but when it comes to cycling it just doesn’t seem as harmful. We should be aware of it, though. It’s not as innocuous as you think.”Dr. Seidman was so interested in the topic that he went on a bike ride in the wind tunnel at Ford Motor Company to examine it more closely.“I was riding at 50 to 60 mph, which is achievable on a bike when you go downhill,” he says. “Basically, if you are riding 1 to 2 hours at 10 mph with wind you could be damaging your hearing.”It’s similar to being at a noisy concert. Your ears recover each time, but over time the more concerts you go to, more and more permanent damage is being done.Dr. Seidman, who was the lead author of the study, Evaluation of Noise Exposure Secondary to Wind Noise in Cyclists, reported the findings with his colleagues on September 18 at the American Academy of Otolaryngology – Head and Neck Surgery annual meeting in San Diego, California.He warns, earplugs aren’t the answer since you won’t be able to hear vehicles as they approach.

US mayor says invest in staff to keep top talent

first_imgRelated posts:No related photos. Previous Article Next Article Comments are closed. The former Mayor of Atlanta, US, told local government HR professionals thatthe only way to recruit and retain staff in the public sector is to make themfeel valued. William Campbell, speaking at the annual Socpo conference, said although localgovernment cannot match the pay levels of the private sector, it can stillcompete for talent by investing in its employees. Campbell, who has just finished his second term as mayor of Atlanta, saidthat after one of the city’s colleges bought a piece of land from the councilhe negotiated educational credits for his staff, allowing them to sign up foras many courses as they wanted free of charge. “The move showed we valued our staff and were prepared to invest intheir learning and development,” he said. Under Campbell’s leadership, Atlanta also introduced four paid days off ayear for staff to take health scans and introduced an annual bonus for staffwho did not take any time off for illness. “We were not only investing in the health of our employees, but thesustained quality of the council’s services.” US mayor says invest in staff to keep top talentOn 26 Mar 2002 in Personnel Todaylast_img read more

HMAS Toowoomba returns from seven-month deployment

first_imgThe Royal Australian Navy’s (RAN) Anzac-class frigate HMAS Toowoomba has returned to its homeport of Fleet Base West, Rockingham, after the ship’s longest deployment to date, contributing to seven task groups in seven months.Commanding Officer, Commander Mitchell Livingstone, said Toowoomba achieved many milestones since February, supporting an extensive series of exercises, international engagements and training activities.“Toowoomba has participated in three exercises, the Principal Warfare Officer Assessment Week, and two regional deployments to engage with our regional partners and further Australia’s interests abroad,” Livingstone explained.Toowoomba has sailed 40,125 nautical miles, or more than 74,000km, equivalent to 1.85 times around the world.“The commitment shown by the ship’s company has allowed us to do much this year, with highlights being our role as Commander of the Exercise Bersama Shield Task Group Maritime Component and the multiple weapons and missile firings we conducted at Exercise RIMPAC,” he added.Throughout the deployment, the ship visited various ports around Australia, Guam, Malaysia, Vietnam, Brunei, Singapore, Vanuatu, the United States, and the Solomon Islands.HMAS Toowoomba is the seventh of eight Anzac-class frigates built by Tenix Defence Systems for RAN.

Animals Overcome Limitations of Physics

first_imgThe limits of human engineering have been overcome by animals in surprising ways worth imitating.Cochlea secrets improve sound reception:  Why does the cochlea in the mammalian inner ear have two fluid-filled chambers?  Prof. Marcel van der Heijden at Erasmus Medical Center, University Medical Center, Rotterdam, wanted to know.  He found that the leading “resonance theory” is wrong; experiments have shown that lab imitations can either get frequency tuning or amplification, but not both.  Van der Heijden’s new model based on the cochlea’s two-chamber design can carry waves and do spectral analysis simultaneously, because it “displays strong structural and behavioral similarities to the cochlea.”  The living cochlea, though, still excels in its ability to perform “multiband dynamic range compression” and “automatic gain control,” among other advanced features.  The new work relies on the theory of “optical coherence tomography.”  The article goes into some detail about how the cochlea works.Shrimp sees cancer:  The mantis shrimp has been a frequent focus of engineering interest for its amazing eyes (1/29/14, 3/31/08 #5) and claws (7/06/14).  Now, an interdisciplinary team at the University of Queensland believes that sensors modeled on the mantis shrimp eye could detect cancer.  PhysOrg says, “Mantis shrimp eyes are inspiring the design of new cameras that can detect a variety of cancers and visualise brain activity.”  That’s because “the shrimp’s compound eyes are superbly tuned to detect polarised light, providing a streamlined framework for technology to mimic.”Butterfly photonics:  One of the early biomimetic stories concerned “photonic crystals” found on insect wings and bird feathers – structures that manipulate light without pigment (1/29/03).  PNAS just published a paper by Harvard scientists who made “Bioinspired micrograting arrays mimicking the reverse color diffraction elements evolved by the butterfly Pierella luna.”  Although evolution was on the lips of the UK team (“In the course of evolution, many organisms have developed unique light manipulation strategies…”), it was not in their techniques.  Those involved intelligent design: “Exploiting and improving the butterfly’s strategy, we create photonic materials that increase our basic understanding of the optical interplay of hierarchical structures and provide a platform for the development of novel photonic devices.”  Among them, Live Science reported, could be “counterfeit-proof tech” because the material is “difficult to create”.Beetle paint:  A related article on PhysOrg discusses a more “natural route” to photonics being investigated across the pond by Oxford scientists: “Researchers take cells from chrysalis and use them to grow butterfly wings in the lab.”  Judging from the durability of these photonic crystals in fossils, it should be possible to create long-lasting colored surfaces that could be painted on.  “They point out that such materials would never fade, noting that similar beetles from millions of years ago that have been unearthed, still have the same colors that had when alive,” the article concludes. “They also note that they believe what they’ve discovered is only the beginning—they envision a host of products grown from a wide variety of cells from fish, peacocks, and many types of insects.”Membrane tech:  A researcher at the University of Leeds sees “endless possibilities for bio-nanotechnology,” says PhysOrg, thanks to the imitation of lipid membranes that cells use to enclose their systems.  That “thin skin” that surrounds biological cells “can be applied to synthetic surfaces,” also mimicking the active transport cells use to control what goes in and out.  The university is using nano-lithography and atomic force microscopy in its attempts, “with high precision, to create novel hybrid bio-electronic devices.”Dolphin sonar:  A physical limitation that challenged man-made sonar systems has been overcome by imitating dolphins.  PhysOrg headlined its story, “Dolphin-inspired sonar overcomes size-wavelength limitation.”  That limitation arises when the size of the sonar arrays is much larger than the wavelength.  The article attributes mastery of sonar to evolution, winning an “Amazing” award as well as “Stupid Evolution Quote of the Week” –While this problem plagues man-made sonar, Yangtze finless porpoises don’t seem to have the same limitation. Through millions of years of evolution and natural selection, the animal has developed a relatively small head (compared to man-made sonar) that can manipulate acoustic waves into a beam with high directivity. Porpoises and dolphins use these highly efficient biosonars for foraging, avoiding predators, and group coordination. Studies have shown that, despite serious vision degradation in water, dolphins can locate centimeter-sized objects 100 meters away using echolocation.Don’t forget us plants:  A clumsy-looking electric “plant” named PLANTOID begins an article on Science Daily about “Robotic solutions inspired by plants.”  The prototype in the picture has “a 3D-printed ‘trunk‘, ‘leaves‘ that sense the environment and ‘roots‘ that grow and change direction.”  Why would a robot designer make like a leaf?  “Humans naturally understand problems and solutions from an animal’s perspective, tending to see plants as passive organisms that don’t ‘do’ much of anything, but plants do move, and they sense, and they do so in extremely efficient ways.”  Because “plants are very efficient in terms of their energy consumption during motion,” using no muscles, your future surgery could benefit from this research.The shrilk joy of it all:  New Scientist has an updated account of Shrilk, a new bio-friendly replacement for plastic made from spider silk and shrimp exoskeleton.  This might be a far better replacement than the current material that Salee Adee says is still inhabiting a landfill somewhere with your baby diapers.  That old polyethylene plastic may last a few centuries more.  A photo shows what shrilk looks like: “a tough, biodegradable replacement for world-choking plastics.”Nano-mold:  Harvard’s Wyss Center for Biologically Inspired Engineering achieved a “significant breakthrough” in nano-technology.  PhysOrg says they have constructed tiny structures made from a familiar biological molecule: DNA.  This ability allows them to “form tiny 3D metal nanoparticles in prescribed shapes and dimensions using DNA, Nature’s building block, as a construction mold.”  A sheet of paper is 100,000 nanometers thick; these DNA molds are as small as 25 nanometers.  “The properties of DNA that allow it to self assemble and encode the building blocks of life have been harnessed, re-purposed and re-imagined for the nano-manufacturing of inorganic materials,” one of the team members said. “This capability should open up entirely new strategies for fields ranging from computer miniaturization to energy and pathogen detection.”Pitcher this:  The Wyss Center also came up with a bio-inspired material for coating medical devices, PhysOrg said.  The material, called SLIPS, repels blood, prevents clotting, and resists bacterial biofilms.  Where’d they get the idea?  “Inspired by the slippery surface of the carnivorous pitcher plant, which enables the plant to capture insects, SLIPS repels nearly any material it contacts.”Design is everywhere from Atlanta to Zoo:  Georgia Tech’s Center for Biologically Inspired Design has created an iPhone app called ZooScape to raise public awareness about biomimetics and to encourage conservation of the animals that have inspired new technologies.  Though usable anywhere, the app becomes interactive at the Atlanta Zoo, where visitors can interact with the lessons in physics coming from animal inspiration.  PhysOrg has a short video clip where Marc Weissburg, professor of Biology at Georgia Tech, says, with feeling, “Animals are really amazing in the things that they do, and we learn so much from them, that there’s actually not one that I don’t look at and say, ‘Wow, that’s really cool!’”  The clip gives an example: flamingoes have a water filter in their beaks that we don’t fully understand, but it might help us improve water faucets some day.  Joe Mendelson, adjunct professor and herpetologist at the zoo, echoed Weissburg’s sentiments. “There’s so much we have learned and still have to learn about animals,” he said. “They’re experts at navigating their environments successfully, and it turns out that sometimes all we have to do to improve our own systems and efficiency is to sit back and watch them do what they already do so well.”Read how Evolution News & Views responded to the Darwinians’ efforts to insert themselves into biomimetics where they don’t belong, trying to make themselves look relevant to the Design Revolution.

They include the host team, Ghana, Cameroon, Côte d’Ivoire, Algeria, Egypt, Mozambique, Togo and Tunisia.It is hoped that the Togolese national team, which fell victim to a deplorable shooting attack just before the start of the tournament and has since returned home, will rejoin the group shortly.Saving the planetAfrica is home to nine of the planet’s 35 biodiversity hotspots, many of which are under threat.The continent also harbours two of the five most important wilderness areas on earth – the Congo Basin, and Southern Africa’s Miombo-Mopane woodlands and savannas, which spans 10 countries and is considered to be the largest known contiguous area of dry woodland.Speaking at the Play for Life launch, Puma CEO Jochen Zeitz said: “Biodiversity and therefore valuing and protecting all life on our planet is a huge issue, not only in Africa, but around the world.”He added that the sportswear giant was proud to partner with UNEP to raise both awareness and funds, as all proceeds from the worldwide sale of the replica kit, as well as Puma’s other Unity products, will be used to support biodiversity projects.The Unity range includes clothing, shoes and accessories inspired by the work of American artist Kehinde Wiley, whose designs have been incorporated into the trendy items.The Play for Life partnership will also feature popular football stars communicating with their fans through public service announcements, entrenching the conservation message and encouraging greater action.Cameroon’s national football team, the Indomitable Lions, attended the launch. Team captain and Internazionale striker Samuel Eto’o said the new kit was an inspiration to him and his team.“Not only are we very proud to wear a shirt that helps bring the continent of Africa together, but to do so for such an important cause is truly an honour,” he said. “Supporting the Africa Unity Kit sends out a positive message for Africa – we are uniting as a continent to help life and the planet.”Colours of AfricaThe strip features earthy colours and elements of nature, designed to inspire and educate.At the shoulders the shirt is a light blue, but further down there is a gradual transition from blue to a rich brown – this represents the African sky and earth. Actual soil samples from Ghana, Ivory Coast, South Africa and Cameroon were the source of the brown tone, which is smoothly and seamlessly carried through to the shorts.The shirt is further adorned with Puma’s yellow Life badge, while other elements – such as the Puma mascot and the player’s number – are also in yellow to represent the African sun.last_img read more

Spending a Day With Energy Policy Geeks

first_imgI recently attended a small, one-day meeting in Atlanta of individuals and organizations involved in energy efficiency throughout the southeast U.S. Hosted by SEEA, the Southeast Energy Efficiency Alliance, the group responsible for distributing much of the ARRA money for efficiency throughout the region.Along with the typical discussions of successes and challenges (or failures) in the region, there were a few standard utility company party-line comments and, somewhat surprisingly, a few off-the-wall comments that suggested a little bit of revolutionary thinking going on in the industry.Opening act: the sky is fallingThe morning keynote address was given by Dr. Marilyn Brown of Georgia Tech and Oak Ridge National Laboratory, who is the author of too many books and reports on energy to mention. Although her slides were almost illegible, she presented some pretty frightening statistics including her calculations that we have used up our carbon budget and only have about five years left to change our direction before climate change takes an irreversible course to someplace we don’t want to go.Since 2005, per capita U.S. energy use has decreased, primarily because the most energy-intensive industries are now mostly in other countries.Finally, addressing our regional audience, the southeast US has about 36% of the country’s population but uses 44% of total energy generation. What a lovely way to start the day.Rethinking public policiesThe most interesting information came out of two panel discussions. The morning session included a discussion of how public policy affects energy industry decisions. The moderator started with a review of current public policy: Electric utilities should produce reliable power at the lowest cost to the consumer; and a potential alternate policy to consider: Electric utilities should produce reliable power at the lowest cost to the environment. Kind of mind-blowingly simple concept, but changing core public policy is not easy, especially when it would likely increase energy costs to the end user.There was a good discussion on renewable energy standards, few of which currently exist in the southeast. North Carolina, one of the few states with a standard, is required to provide 12.5% of its energy from renewable sources by 2021, which has been calculated to cost $34 annually per household – a surprisingly reasonable cost.One panelist suggested that utilities should just charge all their customers for efficiency programs and then ask them if they want to take advantage of them. There’s something about that idea that appeals to me.There was a good discussion of how to effectively finance energy efficiency programs, including on-bill financing. It was pointed out that nationally, the default rate on power bills is 3/10 of 1% – seems like a great place to finance energy efficiency and renewable energy projects.A discussion of time-of-use dynamic pricing was interesting. Some utilities that have tried it were not successful because customers didn’t want to think about it. The consensus was that customers don’t want to make decisions on their power purchases.Duke Energy found that dynamic pricing led to overcharging for peak and undercharging for off peak power to provide enough incentive for customers to change their behavior. Utility managed controllers on HVAC and water heating equipment tends to work better to reduce peak loads.Getting efficiency doneThe afternoon panel included the director of the Charlottesville, Virgina, efficiency program; a developer from New Orleans; the Nashville, Tennessee director of sustainability; and a representative from Duke Energy, discussing the challenge of financing energy efficiency improvements.New Orleans has a program (supported by grant money) that provides financing for less than 4%. Non-subsidized loan programs find it almost impossible to get rates below 6%, due to administrative costs on small loans.Duke Energy threw out one of the best wild ideas of the day – a concept they are working on but have not yet implemented – offering a fixed monthly total bill to their customers based on historical costs. Not a fixed rate, but an actual fixed amount they will pay per month. They believe that it is possible to calculate a figure for each customer that will allow them to include the cost of performing efficiency improvements to a building in a monthly bill while still making a profit and lowering demand. If utilities were to do this, they would have an incentive to do improvements that really work, as they would benefit directly from good work and suffer from poor work.Probably my favorite comment of the day came towards the end of the afternoon panel. It was suggested that utilities should be able to withhold energy from inefficient buildings to help cut demand and incentivize people to improve their efficiency. Now, I don’t think anyone was seriously considering implementing this policy, but it was refreshing to hear uncensored, creative thinking, particularly from usually staid utility companies. I hope that some of the wild ideas I heard help move things forward in the not-too-distant future.last_img read more
