Investigating the use of milk fatty acids to detect dietary changes: a comparison with faecal analysis in Antarctic fur seals

first_imgWe compared the use of fatty acid signature analysis with results from traditional faecal methods using milk samples and enemas concurrently collected from 8 female Antarctic fur seals Arctocephalus gazella foraging from Bird Island, South Georgia. The seals were serially sampled throughout the 1998/1999 breeding season, with collections taken after every foraging trip when possible. The total lipid content of the milk increased throughout the season. A general linear model using 4 principal components showed that it was the point within the breeding season at which a milk sample was collected that had the biggest influence on its fatty acid composition. There were also significant differences in the milk composition of individual seals. However, the results of faecal analysis, which are themselves subject to potential biases, were not correlated with the relative amounts of individual fatty acids. It has been suggested that seasonal changes in the milk fatty acids, previously observed in the same population of seals, are a result of increased consumption of fish. We found no evidence of this in the faecal material and suggest that the seasonal variability may be a result of changes in the fatty acid composition of the seals’ main prey (krill), or because of the changing needs of the developing pups. This study highlights the need for comprehensive testing of milk fatty acid signature analysis before the full potential of this technique can be realised.last_img read more

Has the Mediterranean Sea felt the March 11th, 2011, Mw 9.0 Tohoku-Oki earthquake?

first_imgThe possibility that the tsunami, generated as a consequence of the large Mw 9.0 Tohoku-Oki earthquake of March 11th 2011, could be recorded by the tide gauge stations located in the Mediterranean Sea has been investigated. We find two kinds of transient signatures which should be attributed to the far-field destabilizing effect of the tsunami on the usual tidal components: 1) the excitation of a broad spectrum of frequency fluctuations, superimposed to the diurnal and semidiurnal tidal components, 2) the change of amplitude of the low-frequency tidal components in the Mediterranean, related to the sea surface fluctuation perhaps caused by the direct transmission of the tsunami across Gibraltar.last_img

Eric Holcomb discusses the plans for improvement that DCS will undergo.Photo by Brynna Sentel, TheStatehouseFile.com Holcomb Has A $6 Million Head Start On The 2020 Governor’s RaceJuly 19, 2019 By Brandon BargerTheStatehouseFile.comINDIANAPOLIS – With a year and a half to go until the 2020 election, Republican Gov. Eric Holcomb has more than $6 million in his campaign coffers.That, his campaign said, surpasses the fundraising totals of any previous governor at this point in their re-election bid.Among his contributions: $100,000 from Roger Penske, owner of the winningest team in Indianapolis 500 history.Campaign finance reports due Monday showed that Holcomb began 2019 with about $4 million, and raised another $2.265 million from Jan. 1 through June 30. He spent about $245,000.Holcomb, who kicked off his re-election campaign Saturday with a rally in the Knightstown gym where much of the movie “Hoosiers” was filmed, has added to his account since then, including $15,000 from the Indianapolis law firm Krieg DeVault and $10,000 from Lawrence C. Beck, president of Beck Hybrids in Atlanta, Ind. Beck was recently re-appointed by Holcomb to the Purdue University board of trustees.Holcomb’s single largest contribution came from his running mate, Lt. Gov. Suzanne Crouch, who transferred $1 million from her account to his. She closed the reporting period with about $185,000 left.No Democrat was officially in the race for governor in the first half of the year, so did not have to file a report. So far, the only Democrat to file to challenge Holcomb is Dr. Woody Myers, who announced his candidacy last week.Also filing his campaign finance report was Attorney General Curtis Hill. Hill raised more than $223,000 in the first half of this year, but spent more than $137,000 including more than $33,000 to a Wichita, Kansas, consulting firm.Combined with the $120,000 Hill had at the start of the year, he has more than $206,000 in his re-election fund.While Hill does not yet have a Democrat opponent, he has faced calls from some fellow Republicans, including Holcomb, to resign in the wake of allegations from women, including a Democrat legislator and legislative staff of both parties, that he touched them inappropriately at an end-of-session party in 2018. The women have filed a civil suit and Hill also is facing a disciplinary hearing this fall as a result of the allegations. If found to be at fault, he could lose his license to practice law – something an attorney general has to have.FOOTNOTE: Brandon Barger is a reporter for TheStatehouseFile.com, a  news website powered by Franklin College journalists.FacebookTwitterCopy LinkEmailSharelast_img read more

Harvard’s hand in shaping education

first_imgHONG KONG — On the first day of a weeklong visit to Asia, Harvard President Drew Faust on Monday called knowledge “the most important currency of the 21st century,” highlighting faculty research, student engagement, and online learning as central to Harvard’s global strategy.Faust met with alumni and business leaders in Hong Kong to discuss Harvard’s online learning initiative, HarvardX, and the edX platform developed in partnership with the Massachusetts Institute of Technology.“This is a moment of transformation for education, and we want to be able to lead in a way that allows us to enhance our outreach to the world, even as it helps us understand new ways to teach our students on campus,” said Faust.Of more than 700,000 enrollments through edX, about 60 percent come from outside the United States.“The hunger for knowledge is so strong around the world,” said Faust.  “I feel [HarvardX] is a magnificent opportunity, but it is also a big responsibility for us to set a standard for online learning that upholds the most important aspects of higher education and its values, and allows Harvard to play a leadership role in shaping how education changes in the years to come.”Professor Robert Lue, the HarvardX faculty director, presented the latest thinking on HarvardX and its global presence. He told 30 attendees that 102 Harvard faculty members had demonstrated an interest in developing programs as part of HarvardX, noting that the initiative would allow Harvard to expand its reach and impact globally.Lue said the flexibility of online learning and the edX platform would create opportunities to go beyond MOOCs (Massive Open Online Courses) and develop smaller modules that would encourage collaboration and target particular audiences.“Already, public health faculty who developed the first HarvardX courses are discussing taking one of the modules and tailoring it specifically to bring it to families in Boston, with the possibility of a focus on one key issue, such as childhood obesity,” said Lue. “That was not in the original plan for the course, but we see tremendous potential in the ability to adapt content from its original form.“This is an example of the content bringing people together rather than keeping them apart,” he said.The discussion was moderated by Victor Fung, group chairman of the Li & Fung Group, who has a doctorate in business economics from Harvard and was a professor at Harvard Business School (HBS) in the early 1970s.During her first visit to Hong Kong, President Drew Faust hosted a lunch for leaders from six local institutions of higher education. Faust (left) spoke with Tony F. Chan, president of Hong Kong University of Science and Technology, about the trends in education.Fung said that bringing together online education and traditional, place-based education — whether on campus or in communities — could herald new opportunities and engagement throughout the world.“When you can use the Web to form communities of interest at the local level that can enhance experiences on the Web, you begin to realize that the ‘bricks and clicks’ potential is tremendous,” said Fung.During her first visit to Hong Kong, Faust also hosted a lunch for leaders from six local institutions of higher education, who discussed trends in education.The local leaders told Faust that the continued evolution of Hong Kong’s economy from manufacturing-based to knowledge-based was creating a need for new thinking in higher education, including curriculum reform shifting from three-year to four-year undergraduate degrees, along with a greater emphasis on international issues, service-oriented learning, and the liberal arts.Faust also visited the Harvard Business School’s Asia-Pacific Research Center, the first overseas HBS research center, located in Hong Kong’s Central neighborhood.  The center has contributed to more than 150 research projects and 175 cases since it was founded in 1999, and it encourages engagement with local experts and institutions to support faculty research.Michael Shih-Ta Chen, the center’s executive director, said HBS Dean Nitin Nohria’s emphasis on internationalization had brought even greater focus on Asia, with 370 students coming to the continent as part of the new FIELD global immersion initiative introduced by Nohria to expand students’ exposure to global business.President Drew Faust’s visit to Asia continues throughout the week, including meetings with local alumni groups, and travel to South Korea.last_img read more

Your mail just got a little bit greener

first_imgThe recent conversion of a Harvard Mail Services truck to a hybrid electric vehicle has dramatically reduced fuel consumption. As a result, the eight-month pilot program has cut the vehicle’s greenhouse gas emissions by nearly 22 percent. Now, in addition to delivering thousands of pieces of mail across the University, the van is also delivering a win for the environment.In June 2013, Harvard Fleet Management joined with Boston-based XL Hybrids to retrofit the Mail Services Chevrolet Express van with an innovative, hybrid electric powertrain. The new technology increases efficiency and reduces fuel usage without sacrificing performance.“We chose to pilot the use of this hybrid technology so that we can do our part to support Harvard’s commitment to sustainability, including the goal to reduce greenhouse gas emissions across campus,” said David Harris Jr., director of Harvard Transit and Fleet Services. “Instead of buying a brand-new hybrid vehicle we were able to save money and increase the fuel efficiency of our existing fleet, resulting in an immediate return on investment.”To convert the Mail Service van, XL Hybrids added an electric motor with a lithium ion battery pack and cutting-edge control software that increases fuel efficiency by charging the battery when drivers brake and releases energy to the motor when drivers accelerate. A review of the van’s on-road operational data showed a nearly 22 percent fuel and greenhouse gas emissions reduction over conventional cargo vans, yielding an annual CO2 reduction of over one metric ton per vehicle.

Crop update

first_imgBy April SorrowUniversity of GeorgiaGeorgia Vidalia onions and peaches need wintry temperatures to produce their best in spring and summer. So far, conditions have been excellent, say University of Georgia experts. “Right now, the Vidalia onion crop is progressing very nicely. We expect acreage to be pretty stable,” said Reid Torrance, the UGA Cooperative Extension coordinator in Tattnall County, where 60 percent of the crop is grown. Approximately 80 percent of the expected 12,000 acres has been planted. Recent rain has made planting more difficult. “We are having to hop around to find fields dry enough for planting,” he said. He expects farmers to grow 600 acres of organic Vidalia onions, a 50 percent increase over last year.“Onions are very tolerant to cold when they are young,” Torrance said. “But, we don’t want a real cold winter. Temperatures in the low teens and single digits bring a risk of cold injury. By the same token, a warm fall and early winter can cause onions to grow too much too soon.” Several winters in the 1980s wiped out the crop. But more cold-tolerant varieties now help prevent that, he said. The last devastating freeze happened in 1996. Improved varieties and management has helped farmers control diseases in recent years, too.Onion farmers seed planting beds in September and transplant the young plants from the beds to fields in November and December. They harvest onions in April and May. To be an official Vidalia onion, the onion must grow in one of only 20 counties in southeast Georgia designated by the Vidalia Onion Act of 1986.While onions use the cool winter months to mature underground, Georgia peach trees need chill hours, or hours below 45 degrees Fahrenheit, to stay dormant. This helps them bloom properly in the spring and produce fruit in the summer. “Depending on the variety, Georgia peaches like to get between 400 and 1,100 chill hours between October and Feb. 15,” said Frank Funderburk, UGA Extension coordinator in Peach County.Georgia has 12,000 to 14,000 acres of peaches scattered throughout the state. But most grow in central Georgia. As of Dec. 8, Peach County had received 375 chill hours. “We are ahead of the last three years. We are looking good,” he said.In recent years it hasn’t been a lack of chill hours, but rather a late freeze that hurt the crop. Freezes in 2007 and 2008 cut the crop by half, he said. “We can make a crop with low chill hours, but we won’t make a crop if temperatures drop too low after buds start to develop,” Funderburk said. A freeze in 1996 destroyed the entire crop.“We are hoping for a better year in 2009. By mid-January we will have a good idea of where we are,” he said.

Irrigation Maintenance

first_imgTo avoid disaster due to subfreezing winter temperatures, leaky pipes and uninvited rodents, University of Georgia Cooperative Extension irrigation specialist Wes Porter recommends that Georgia growers inspect their irrigation systems before planting their crops this spring.“We’ve got to get our irrigation systems in top shape, up and ready to run. Once the crops are up, the last thing you want is an irrigation system to break down,” Porter said.Planting season is just weeks away for Georgia corn growers, who normally start planting at the beginning of March. Now is the best time to inspect irrigation equipment, Porter said.“I encourage (growers) to do a quick search online or go to their county (Extension) office and ask for our spring center-pivot checklist,” he said. “It goes through the components (that growers) should check very thoroughly, has detailed pictures of the critical areas to check, discusses what to look for and even how to correct most of the problems.”The center-pivot maintenance guide can be found online in UGA Extension Bulletin 1452, located at extension.uga.edu/publications/detail.html?number=B1452.After farmers begin planting their crops, they may apply irrigation to establish proper plant stands or activate herbicides, and a leaky pipe or flat tire can delay those plans.“If farmers take care of these maintenance procedures before the growing season begins, it will save them much-needed time during critical water-use periods and prevent potential yield loss to their crops due to moisture stress,” Porter said.Growers should test irrigation systems and let them run to make sure they are operating efficiently prior to their initial use on this season’s crops, he said.“Start the system up and make sure it’s working with proper operating pressure. It’s a good idea to check the flow rate to make sure (it’s) where it is supposed to be. You can also visually check all the nozzles to ensure they’re all working properly,” Porter said.Growers should also make sure that sprinklers are rotating properly, in a uniform pattern.Change the oil and clean the air filters on motors that run on diesel, gas or propane. Make sure that pumps are ready and free of overwintering animals or insects, their nests and cobwebs.UGA Extension water educators can come to growers’ fields to take uniformity tests. Through these tests, they can check water distribution across a pivot and find where growers can potentially save money.To learn more about UGA Extension water educators, visit http://bit.ly/2BHrncS.last_img read more

East Moriches Man Made Child Porn from Public Photos, Feds Say

first_imgSign up for our COVID-19 newsletter to stay up-to-date on the latest coronavirus news throughout New York Federal authorities arrested an elderly East Moriches man they said cut-and-pasted faces of children he photographed in public into hundreds of adult pornographic images—some in which he added his own face.Jay Lockett Sears, a 73-year-old high-profile architect, was scheduled to be arraigned Friday at Central Islip federal court after being charged with possessing child pornography. He faces up to 10 years in prison if convicted.“Sears victimized countless children by using their innocent images to create child pornography,” said Loretta E. Lynch, U.S. Attorney for the Eastern District of New York. “He then went so far as to use his own image to virtually join in the exploited scenarios he created.”Suffolk County police became aware of his case Jan. 11 when numerous bags containing hundreds of child porn images were found in trash removed from his apartment. The images were discarded in anticipation of Sears vacating his apartment.Parents who believe that their children may have been the victims of child pornography should contact the Suffolk County Computer Crimes Squad at 631-852-6279 or the Federal Bureau of Investigation at 631-501-8600.last_img read more

Wake up! These three things are keeping you tired

first_imgThere are days when I’m filled with energy, ready to take on the day. And then there are some days where no matter what, I’m sleepy. Are you habitually sluggish and in need of an energy boost? Consider these three things you may be doing that are keeping you tired and whether certain simple changes can perk you up.Not eating enoughSwimsuit season is around the corner and many of us feel the need to drop some weight. Remember that your body needs certain nutrients throughout the day to stay healthy and alert. Just because you’re trying to lose weight, doesn’t mean you should cut out things your body needs to be effective. Instead, look into certain simple diets to help you shed the pounds, while still allowing you to enjoy eating.Strange sleep scheduleIt can be difficult to go to sleep at the exact same time every day. Sometimes you want to stay up and binge on Netflix. Other times your children can’t stay asleep so your nighttime routine is out of whack. The key to feeling rested the next day is doing the best you can to limit inconsistent bedtimes. It’s not always easy but the more structure you have, the more appreciative your body will be.Avoiding exerciseWhen you’re sleepy and want to relax, the last thing you’ll feel motivated to do is exercise. If you can muster the strength and get moving, trust me, you’ll be glad you did. I’m one who doesn’t care to exercise, but when I do, I feel a great deal better. Working out may be hard to initiate but the health benefits are undisputed. So whether it’s heading to the gym, the outdoor track, or simply a nice walk through the neighborhood, take time out of your day to stay active. Making this a part of your regular routine is a sure-fire way to feel less tired in the days to come.Save 55SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,Wendy Moody Wendy Moody is a Senior Editor with CUInsight.com.
