“Watermark Ink” device identifies unknown liquids instantly

first_imgMaterials scientists and applied physicists collaborating at Harvard’s School of Engineering and Applied Sciences (SEAS) have invented a new device that can instantly identify an unknown liquid.The device, which fits in the palm of a hand and requires no power source, exploits the chemical and optical properties of precisely nanostructured materials to distinguish liquids by their surface tension.The finding, published in the Journal of the American Chemical Society (JACS), offers a cheap, fast, and portable way to perform quality control tests and diagnose liquid contaminants in the field.“Digital encryption and sensors have become extremely sophisticated these days, but this is a tool that will work anywhere, without extra equipment, and with a very wide range of potential applications,” says co-principal investigator Marko Lončar, associate professor of electrical engineering at SEAS.Akin to the litmus paper used in chemistry labs around the world to detect the pH of a liquid, the new device changes color when it encounters a liquid with a particular surface tension. A single chip can react differently to a wide range of substances; it is also sensitive enough to distinguish between two very closely related liquids.Watch a video of the new process.

Sunbelt Expo

first_imgThousands of high school and college students visited the University of Georgia building at the Sunbelt Ag Expo in Moultrie, Ga. last week.Brice Nelson and his group of student ambassadors from the College of Agricultural and Environmental Sciences were there to greet them. Nelson, a student recruitment coordinator on the UGA campus in Athens, is hopeful something he or one of the college students said during the three-day event swayed the thought process of a prospective student.“It’s more of a visibility, public relations type of thing and an awareness event for our potential students,” Nelson said. “I think we’ve been able to give out some information that they can use, either through the freshman process or transfer process, and hopefully it can make the application process to the University of Georgia a little bit easier.”The recruiting tools at Nelson’s disposal were the CAES Student Ambassadors at the Expo. Potential students talked with the current UGA students to get first hand advice.“Certainly having the CAES Ambassadors here is a highlight of our exhibit, with them interacting with potential students and potential students being able to ask our current students questions that are relevant to the campus, student life and academics,” Nelson said. “We hope they can get it from a first-person prospective. Our students enjoy coming here and providing information to the public.”One of those students is Sarah Harrison, a CAES junior from Tifton. Though Thursday wasn’t her first visit to the Expo, it did mark her first time as a Student Ambassador from Athens. “Some people around here, they might not know about the (college). We’re making sure everyone is just aware of what we have to offer them,” Harrison said. To learn more about CAES undergraduate program, visit the website students.caes.uga.edu.Cooperative ExtensionAcademics is just one aspect the college tried to showcase during the event, which attracts about 100,000 people annually. Another program on display was UGA Cooperative Extension. Thomas County Extension agent Andrew Sawyer attended the Expo and still finds there are those that aren’t fully informed about Extension’s existence. Weeks like this allow Sawyer and other agents to get the word out about the program.“This is a super-educational opportunity for us, just to let folks know that we’re there. No matter where they’re at, in whatever county, they can call somebody,” Sawyer said.For more information about UGA Extension, see extension.uga.edu.Forages and ForagersUGA’s Expo theme this year was Forages and Foragers. The college used the three days to highlight its forage research programs, the beef cattle industry and dairy program. UGA beef cattle specialist Jacob Segers and his colleagues talked about how cattle digest forages and animal by-products like shampoos, conditioners and nail polish.“Interactions with people at the Sunbelt are usually brief so you try to cram as much information as possible into as few minutes,” Segers said. “It’s a great way to connect with the public. A lot of it is very foreign to a lot of people that come through here. It’s good to get them exposed to it.”To learn more about the UGA beef program, see ugabeef.caes.uga.edu. Information on UGA’s forage program can be found at georgiaforages.com.Cotton pickingUGA faculty members were also in the Expo fields manning demonstration areas. Glen Harris, an Extension agronomist and expert in environmental soils and fertility, assisted with cotton-picking demonstrations and shared cotton research trial results.“Cotton is a huge crop for us, of course. We actually get a lot of people that have never seen cotton harvested,” Harris said. “I’ve got a lot of research plots. The Expo staff is really good to me, helping me all year with my research plots. In return, I help direct the picking demonstrations where to go. It’s a lot of fun for me.”The Expo included information for farmers of all ages.“You get somebody that’s a little older, they like to talk about how they used to do it,” Harris said. “In fact, my research plots, I use a one-row Case machine that’s a 1952 model. You compare that to the six-row pickers, it’s a huge change.”last_img read more

Great American Beer Fest Winners

first_imgThe Great American Beer Festival took place in Denver over the weekend. It’s the largest beer festival in the country, with the most widely respected competitions in the world. Breweries from coast to coast converge on the Mile High City to see who has the best IPA, best amber, best fruit beer…And the Southern Appalachians had a strong showing in that competition.Hi-Wire Brewing, out of Asheville, pulled down gold for their Zirkusfest Oktoberfest, a malt-forward lager with a crisp finish. NoDa won a medal for their Nodajito, an herbal/spiced beer, and there was plenty of hardware to pass around for the Virginia breweries too, with Devils Backbone landing two golds, and Ornery and Ocelot Brewing each winning a gold.zirkusfest-oktoberfest-lager-pBut the biggest winner from our region has to be the tiny Brown Truck Brewing out of High Point, which won a gold for their #10 American Lager and two silvers in the saison categories. They even walked away with the honor of being Champion Brewery in the “Very Small Brewing Company” category.You can see the full list of winners here. You’re going to have to make the trip to High Point to drink one of Brown Truck’s lagers or saisons, but bottles and cans of Hi-Wire’s marzen and Devils Backbone are around. And it just so happens to be prime marzen season, so Zirkusfest should be at the top of your beer hunting list. The beer is rich without being heavy, and packs all kinds of biscuit notes before finishing rather dry. Consider this a “bridge beer” to get your palate warmed up for the maltier, heavier beers of winter. Related:last_img read more

UK reports H5 flu outbreak in turkeys

first_imgNov 12, 2007 (CIDRAP News) – Veterinary officials in England today announced an avian influenza outbreak in turkeys at a farm in Norfolk, after initial tests showed that the birds were positive for an H5 strain of the virus.Officials are awaiting full test results to determine if the turkeys have the highly pathogenic H5N1 strain of the virus, according to a press release from England’s Department for Environment, Food and Rural Affairs (DEFRA). Fred Landeg, acting chief veterinary officer, told BBC News today that he expects test results in the next 24 hours.To date, the deadly H5N1 strain has been identified in British poultry just once, at a turkey farm in February of this year.The site of the new outbreak is a farm 107 miles northeast of London, near the town of Diss, that also has ducks and geese, DEFRA said. All of the birds will be slaughtered. The number of birds slated for culling is about 5,000, according to the BBC report.Authorities have established a 3-km protection zone around the farm, along with a 10-km surveillance zone. “We are also urgently considering with ornithological and other experts what wider measures may be needed,” DEFRA said.Landeg said the disease was discovered yesterday when a veterinarian noted an increasing number of turkey deaths in one of the farm’s five barns, according to the BBC report. He said the affected birds had access to the outdoors and may have been at increased risk of contracting the disease from wild birds, which migrate in autumn.A few weeks ago, the chief veterinarian for the United Nations Food and Agriculture Organization warned that apparently healthy geese and ducks in Europe could be harboring the H5N1 virus. He advised authorities in regions that have significant duck and geese production to reinforce their monitoring and surveillance systems.In the UK’s February outbreak, the lethal H5N1 virus was found at the Bernard Matthews turkey operation in Suffolk, about 70 miles northeast of London. The source of the virus, which led to the culling of 152,000 birds, was never conclusively identified, but authorities said it was probably contaminated turkey meat imported from Hungary.The UK had an outbreak of a different avian flu type in March. In that case, a low-pathogenic H7N2 virus was detected at two small farms, one in northern Wales and one in northwest England. The outbreaks were linked to a handful of mild cases in humans.The lethal H5N1 virus has turned up in wild birds in Britain once, in a swan found dead on the coast of Scotland in March 2006. Also, the virus was identified in October 2005 in a parrot that had been imported from Suriname and quarantined in Essex with birds imported from Taiwan.See also:Feb 5 CIDRAP News story “England reports first H5N1 poultry outbreak”May 29 CIDRAP News story “Welsh officials announce four H7N2 flu cases, suspect human-to-human transmission”Oct 26 CIDRAP News story “FAO warns H5N1 may be lurking in Europe”Apr 6, 2006, CIDRAP News story “Avian flu reaches Scotland as FAO reports progress”last_img read more

Swiss pension funds cautious of ‘captive’ relationship with local banks

first_imgSwiss pension funds are increasingly aware they must not be seen as captive clients of the country’s largest banks, a locally active currency manager has argued.James Wood-Collins, chief executive at Record Currency Management, attributed some of his company’s growth in Swiss hedging mandates to an increasing awareness of the counterparty risk inherent in employing the custodian bank to safeguard against currency fluctuations.According to IPE’s annual survey of managers of Swiss institutional assets, the company has seen local institutional assets increase from €14bn to €25.4bn, while assets managed on behalf of pension clients more than doubled to €22bn in the nine months to the end of June.“One of the many changes that has taken place throughout the financial crisis is the standing of at least some of the Swiss banks in their local community has taken quite a hit,” said Wood-Collins, noting that the institutions were no longer as well regarded as they used to be.  “As a result of that, pension funds are increasingly aware they can no longer be seen to be captive clients of any one bank relationship – and that goes both to the prices they receive for the hedging and the concentration of counterparty risk that arises if they only have one bank relationship.”Despite such concerns, asset managers associated with two of Switzerland’s largest banks – UBS Global Asset Management and Credit Suisse Asset Management – have seen their assets under management increase in the nine months since September 2013.The IPE survey showed that UBS Global AM had seen its share of Swiss pension assets increase from €38.6bn to €52.7bn over the period.Assets disclosed by Credit Suisse AM were harder to compare across 2014 and 2013’s surveys, as the company did not disclose like-for-like data.However, it said corporate and institutional Swiss clients entrusted it with €215bn at the end of June 2014.Wood-Collins predicted his company would continue to see interest in hedging, but not only due to the requirement of Swiss funds to ensure they protected themselves against rate changes.He questioned how long Switzerland’s central bank (SNB) would be able to maintain its “loss-making” cap to the euro, which pension funds initially welcomed, despite concerns over inflation.“If the SNB were to change that policy, the market would immediately price it in, almost instantaneously – far more quickly, certainly, than anyone could react,” he said.“All our clients are maintaining their hedge on the euro.”For more on the Swiss pensions sector and the 2014 IPE survey of Swiss institutional managers, see the current issue of IPElast_img read more

‘Joke’ community work sentence for man who beat, deafened wife

first_imgNZ Herald 7 August 2016Family First Comment: “We’re never going to change the culture if we don’t give a strong message to violent offenders.”A man who beat his wife as she held their baby, hitting her so hard in the head that he deafened her, has been sentenced to just 130 hours of community work.But he will likely be deported before he can complete the sentence, described as a “joke” by his victim.Jone Vuetaki, 26, was sentenced to 130 hours of community work in the Timaru District Court on Tuesday for the vicious assault of his wife in November last year.The Fiji-born meat worker denied the charge but was found guilty after a trial before Judge Joanna Maze.Victim advocate Ruth Money was appalled at Vuetaki’s sentence.“This joke of a sentence simply serves to enable and grow New Zealand’s notorious family violence epidemic.”“It is no wonder that the victims of such violence in New Zealand have little faith in the system and are reluctant to report violence when offenders are given such nonsense sentences.”She said the courts needed to come down harder on perpetrators of family violence in order to make any difference.“This disgraceful family violence behaviour is not deterred when some judges in New Zealand continue to make a mockery of the system and community that they are there to serve.”Family First national director Bob McCoskrie echoed Money’s message.“The judiciary needs to reflect the disdain the New Zealand public have for family violence by giving a sentence that reflects the seriousness of the crime,” he said.“In this case… there is also the aggravating issue that a baby was present during this particular altercation who could have easily been seriously harmed by the violence.”He said Vuetaki’s sentence was inadequate, and he doubted whether it would have any real impact on the offender.“Doing some community service simply doesn’t communicate the seriousness of the situation.“We’re never going to change the culture if we don’t give a strong message to violent offenders.”“This is a weak sentence with a weak message,” he said.READ MORE: http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=11688724last_img read more

Consistency is key for Killingbeck in quest for Big Daddy Southern Region rookie title

first_imgBig Daddy Race Cars Southern Region IMCA Sunoco Hobby Stock Rookie of the Year Richard Killingbeck. (Photo by Crimson ‘n Cream Photography) CORTEZ, Colo. – A decade after hanging up his helmet, Richard Killingbeck returned to racing to earn rookie of the year honors in the Big Daddy Race Cars Southern Region for IMCA Sunoco Hobby Stocks.From Cortez, Killingbeck became the first Colorado driver to win the regional ROY prize for the division on the strength of one feature victory and another 10 top five finishes in just 24 starts.“I’d driven a Ford Escort years and years ago in a non-sanctioned wasp class. It had been 10 years since I raced but I’d been wanting to get back in it,” he said. “I was out on the golf course one Saturday and heard the cars on the track hotlapping. I caught the bug and got pulled back in.”Getting a car was first on the to-do list. Killingbeck used Facebook to locate a pure stock in Price, Utah, got it home and converted it to an IMCA legal ride.He rebuilt it in just three days after a crash only six starts into the season. Killingbeck found victory lane five weeks later, in the July 6 show at Aztec Speedway.“That was an exciting race. I was very pleased with the way my rookie season went and hopefully we can build on our success next year, he said. “I’ve got a lot of family and friends who have helped me this season. Jerry and Archie Clark let me use their shop for both the original build and the rebuild.”Killingbeck finished third in point standings at both Aztec Speedway and his hometown Montezuma County Fairgrounds Speedway.He was also third in the Border State Challenge for drivers at the two tracks.“My biggest goal at the start of the season was to stay in the top 10 points for that. Then I adjusted my goal to stay in the top three,” said Killingbeck. “I looked on the IMCA website and in the IMCA newsletter and saw my name rising in the rookie standings and kept racing for points.”Wins-1                    Top Five Finishes-11         Starts-24HIS CREW: Father Gene Ring and Justin Lewis.HIS SPONSORS: Advantage Glass, Champion Graphics and Sparks Plumbing, all of Cortez.last_img read more

DOJ: No charges in Chokehold Death of Eric Garner, family “Can’t Breathe”

first_imgFederal prosecutors are not going to file civil rights charges against the NYPD cop involved in the death of Eric Garner.Garner died while being arrested for suspicion of selling single cigarettes from packs without tax stamps.He denied selling the cigarettes and said, “he was tired of being harassed.”Garner, a 43-year-old, 350-pound father of six, was held in a chokehold for 15 seconds during his arrest.He previously worked for the parks department but had to quit due to health reasons.Garner’s mother Gwen Carr was outraged after officials told her about the decision during a meeting in Brooklyn on Tuesday.“Five years ago my son said ‘I can’t breathe 11 times,’ and today we can’t breathe,” Carr said at a press conference Tuesday.We can’t breatheThe decision comes one day before the fifth anniversary of Garner’s death and the expiration of the statute of limitations.In July 2015, the family received $5.9 million in an out of court settlement from the city of New York.Garner’s family members were hoping to get one last chance to convince federal prosecutors that they should criminally charge Officer Daniel Pantaleo.Garner’s death was ruled a homicide by the city medical examiner’s office, but a grand jury on Staten Island did not charge Pantaleo.Protests are set to take place in Manhattan and Staten Island on Wednesday.Carr said via Twitter Tuesday that “This is not the end.”last_img read more
