Riometer and HF radar signatures of polar patches

first_imgPolar patch was the name given originally to a spatially limited enhancement of the 630-nm emission observed in the dark polar cap. More recently, the term has been applied to related phenomena observed by other experimental techniques. The interrelationship between patches observed by differing methods has yet to be determined fully. In this paper the signatures of a series of polar patches observed by Halley HF radar and the South Pole broad-beam and imaging riometers are presented. Most frequently, the HF radar patch signature immediately precedes that of the riometer polar patch signature. The interpretation is that the leading edge of the electron concentration structure that forms the patch is steeper than its trailing edge. On a few occasions, HF radar polar patch signatures coincide with the trailing edge of riometer patches and sometimes are seen throughout the riometer patch. Halley digital ionosonde data are used to show that riometer patches are more common over South Pole when the maximum F region plasma concentration is considerably in excess of 5×1011 m−3, which often occurs in the afternoon plasma convection cell.last_img read more

Politico’s Maggie Haberman says 2013 elections hold little ‘predictive value’

first_img Read Full Story Reflecting on the 2013 elections and what they might mean for 2014 and 2016, Maggie Haberman, senior political reporter for Politico, shared with the Shorenstein Center three key outcomes that might shed light on future political developments.The three elections she pointed to were Bill de Blasio in the New York mayoral race, and the gubernatorial races of Terry McAuliffe in Virginia and Chris Christie in New Jersey. The conventional wisdom that has followed de Blasio’s election, Haberman said, is that his win “spells a more liberal tilt in the electorate at large, and certainly in politics in New York City.” However, she pointed out, the percentage of voters in this election was a small percentage of the electorate, and so the win “doesn’t speak about a larger theme in either 2014 or 2016.”A narrative that emerged from McAuliffe’s win, Haberman said, is that “the hard-right candidate can’t win.” Yet she sees that instead of a Democratic win, the election showed how close the Republicans came to winning, and as a result, “instead of seeing a dispirited Tea Party, you’re seeing a more invigorated Tea Party and a dispirited Wall Street and a dispirited donor class.”Christie’s reelection, Haberman said, was more a result of unique circumstances than a sign of things to come. Even though he won by a large margin, she said, “the suggestion that there’s a larger lesson that can be learned or tried elsewhere in the Republican Party…is hard to see.”Listen to the audio on SoundCloudlast_img read more

Radish oil

first_imgBy Sharon DowdyUniversity of GeorgiaCorn and soybeans are excellent crops for use in ethanol and biodiesel production, but chickens, cows and people like to eat the crops, too. University of Georgia engineers are searching for non-food crops that can be used to make alternative fuels.The oilseed radish is one crop that could be used to produce biodiesel in Georgia, said Dan Geller, a biological engineer with the UGA College of Agricultural and Environmental Sciences.Canadian cover cropThe radish is widely grown in Canada as a cover crop, or one that is planted to improve the soil and prevent erosion in fields. But it isn’t typically grown for food.Its seed is about 40 percent oil by weight, said Nicholas Chammoun, a CAES graduate student working with Geller. This makes it an excellent candidate for the biodiesel market. For his research, Chammoun had oilseed radish seeds crushed by the U.S. Department of Agriculture National Peanut Research Laboratory. The oil was then converted into biodiesel by the CAES biological and agricultural engineering department.“This sounds like a short and easy process,” he said. “But it actually took a long time since there was very little data on converting oilseed radish oil to biodiesel.”Engine-testedNext, he had to prove the new biodiesel would actually work in diesel engines and perform as well or better than No. 2 diesel and other existing biodiesels.The oilseed radish biodiesel passed the engine tests, performing much like No. 2 diesel, he said.With the help of the UGA Center for Agribusiness and Economic Development, Chammoun determined whether farmers would benefit economically from growing the crop.“No matter the crop, it will take land to produce it,” said John McKissick, director of the center. “It’s still a battle for food production over fuel production on the same limited land. In Georgia, food is still more economically viable.”The economic research data on the radish as a biodiesel crop was also used to assess its economic potential as a Georgia cover crop. “They would harvest in the spring, and the crop would also protect the soil in the winter,” Geller said. Roots aerate soilAnd as a cover crop, its extra-long tap root breaks up and aerates soil and draws up nutrients for the following crop, or one grown for food or fiber.Georgia farmers could grow peanuts and cotton in the summer months and follow with a crop of oilseed radish in the fall.“Oilseed radish isn’t grown for the food market, but it can be grown for the fuel market,” Geller said. “And it can be grown cheaper with a greater oil yield per dollar than soybean, and with lower inputs.”The economic evaluation showed the oilseed radish had potential to be an economically viable crop for Georgia, McKissick said. But more research is needed to determine the yield and costs of producing the crop. Crushers neededGeller calls the university’s research results promising but notes there is one large missing piece to the puzzle. “We can get the seed, and the agronomic data is available,” he said. “The farmers just need someone to crush the seed. The big kicker is which comes first, the farmer or the crusher?”Crushers are companies that process seeds to extract oil.If crushers are found, Geller says Georgia farmers could begin growing these new crops in a few years. CAES researchers are also studying the use of algae, switchgrass and sunflower as oil sources for biodiesel production.last_img read more

Strong credit union loan growth in 2017

first_imgCredit unions can plan for another year of solid loan growth in 2017.Loan portfolios at the nation’s not-for-profit financial cooperatives increased at a hefty 10.6% rate in 2016 and have increased at double-digit rates annually since 2015 – a three-year feat not seen since the mid-1980s.Some find themselves wondering if recent strong loan increases are sustainable.  An increasing number of observers are voicing concern about the outlook for 2017 and beyond.  The current economic recovery has been slow; inflation pressures are more obvious and interest rates are drifting up. Meanwhile, talk of trade war and rising geopolitical risks are further stoking uncertainty.However, there are five key reasons to remain optimistic about credit union loan growth:Credit union members will likely demand more credit to finance purchases in 2017For evidence that consumer demand for credit will be relatively high in 2017, look no further than recently-released data for the Bureau of Economic Analysis (BEA).  The BEA has been tracking the average age of fixed assets and durable goods since the 1920s.  Current data – released late in 2016 – shows that the average age of consumer durable goods now sits just a tick under post-WWII highs.The ability to handle more borrowing is quite highAlthough debt in the household sector has been generally increasing since the middle of 2011, consumer debt-to-income and debt-payment burden ratios are both sitting near cyclical lows.  This means that consumers can afford to take on more debt in the current environment.The economy created at least 2.2 million new jobs in each of the past five years and is on pace to tally 2.1 million in 2017.  Nearly every industrial sector is adding positions. Consumer confidence – by every measure – is soaring.  The Conference Board Consumer Confidence index increased in both February and March of 2017 – hitting its highest level since year-end 2000 with the March reading of 124.4.  And the stock market has been bouncing around near all-time highs; it’s up 6.6% in the first four months of 2017, 15% higher than a year ago.Credit unions have a lot of new membersStrong growth in credit union memberships also will help to fuel loan growth in 2017 and into 2018.  Collectively, credit unions reported an astounding increase of 4.25 million memberships in 2016 – a 4.1% increase which is the fastest annual jump since 1986.Members are willing to take on more debt during the yearAll these new members are keeping loan departments very busy.  The CUNA Monthly Credit Union Estimates report shows the dollar amount of loans in credit union portfolios grew by 11.5% in the year ending February 2017 – an increase in the momentum seen over theThe nation’s member-owned cooperative depositories are delivering increasing valueThe credit union value proposition helps to maintain those numbers.  One example: According to Datatrac, a firm that tracks financial institution pricing, credit union new car loan rates remain well below those at the nation’s for-profit banks.Looking forward, the Federal Reserve will likely be increasing its Federal Funds target rate further in 2017 and 2018. However, those rate increases are unlikely to resemble the increases in previous cycles given relatively weak overall economic growth and still-obvious labor market dislocations.To stay up to date on credit union economics, visit cuna.org/economicupdate. 39SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,Mike Schenk Mike Schenk has over 25 years of experience in the financial services industry.
