Geothermal heat flow in Antarctica: current and future directions

first_imgAntarctic geothermal heat flow (GHF) affects the temperature of the ice sheet, determining its ability to slide and internally deform, as well as the behaviour of the continental crust. However, GHF remains poorly constrained, with few and sparse local, borehole-derived estimates and large discrepancies in the magnitude and distribution of existing continent-scale estimates from geophysical models. We review the methods to estimate GHF, discussing the strengths and limitations of each approach; compile borehole and probe-derived estimates from measured temperature profiles; and recommend the following future directions. (1) Obtain more borehole-derived estimates from the subglacial bedrock and englacial temperature profiles. (2) Estimate GHF from inverse glaciological modelling, constrained by evidence for basal melting and englacial temperatures (e.g. using microwave emissivity). (3) Revise geophysically derived GHF estimates using a combination of Curie depth, seismic, and thermal isostasy models. (4) Integrate in these geophysical approaches a more accurate model of the structure and distribution of heat production elements within the crust and considering heterogeneities in the underlying mantle. (5) Continue international interdisciplinary communication and data access.last_img read more

Grant funding helps UK exhibitors at Anuga

first_imgBritish bakery companies are being urged to take advantage of grant funding made available to businesses planning to exhibit at international food and drink trade show Anuga.The exhibition, which is marketed as housing 10 trade shows under one roof, runs from 10-14 October 2009 at the Cologne Exhibition Centre in Germany. Eligible exhibitors can claim a UKTI grant of £1,400 towards their participation costs.The show features a bread & bakery and hot beverages section, as well as fine food and organic, and has an exhibition space of 300,000sq m.The last Anuga show in 2007 saw 163,348 trade visitors attend – 54% of which came from abroad. This year, 60 companies are expected to exhibit across the UK pavilions, with 21 first-timers signed up, including Glebe Farm, which produces gluten-free bakery products and mixes. Dorset-based Honeybuns will also be exhibiting for the first time.Formerly organised by Food from Britain, the UK pavilions are now organised by PS8, run by directors Sandra Sullivan and Paddy Edwards.“PS8 is thrilled to be working with so many exciting companies at Anuga this year and our hard work has paid off, with the group almost sold out,” commented Sullivan. “With such strong international opportunities available to all levels of exporters, we urge anyone who has not yet booked their stand to contact us urgently to check availability.”PS8 Ltd is the UKTI-appointed Accredited Trade Organiser (ATO) for Anuga.

North Korea: Country behind a curtain

first_imgAs the world watches the succession process unfold in North Korea, countries such as China, Japan, and Russia, whose interests diverge on many important global fronts, are unified in hoping the process goes smoothly for the perennially troubled, nuclear-armed nation.“Everyone wants stability,” said Reischauer Institute of Japanese Studies Director Andrew Gordon, summing up views from the neighboring states.Harvard authorities on China and Russia said during a panel discussion Monday that although those nations’ relations with North Korea are better than the West’s are, even Beijing and Moscow are left confused when trying to figure out North Korea.And when Russians — who know something about running a country that keeps outsiders guessing — describe a country as opaque, you know that clues are hard to come by, said Mark Kramer, program director of the Project on Cold War Studies at the Davis Center for Russian and Eurasian Studies.The situation isn’t much better in China, which is North Korea’s major — and perhaps only — ally, according to Anthony Saich, the Daewoo Professor of International Affairs at Harvard Kennedy School and director of the Ash Center for Democratic Governance and Innovation.“Most Chinese officials are just as baffled as we are by North Korea,” Saich said.Saich, Kramer, and Gordon, together with Carter Eckert, the Yoon Se Young Professor of Korean History, aired their views on events in North Korea since the death of leader Kim Jong-il in December and the succession of his youngest son, Kim Jong-un, as “supreme leader.”The program, “Succession in North Korea: Perspectives from Harvard,” filled the Center for Government and International Studies’ Tsai Auditorium. It featured Eckert, Kramer, and Saich, and was moderated by Gordon. Korea Institute Director Sun Joo Kim introduced the event, which was sponsored by seven Harvard organizations, including the Ash Center, the Asia Center, the Davis Center, the Fairbank Center for Chinese Studies, the Kim Koo Forum on U.S.-Korea Relations at the Korea Institute, the Reischauer Institute, and the Program on U.S.-Japan Relations at the Weatherhead Center for International Affairs.China wants a stable North Korea because it may have more at stake than other nations with respect to that nation’s future. Bound to North Korea by treaties and trade, China could face major problems if destabilization leads to war, Saich said. Japan, meanwhile, sees itself as a likely target if destabilization occurred and led to a desperate search for a common enemy to unify the people behind a North Korean leader, Gordon said. Stability is critical because the north has nuclear weapons, the further development of which those nations would like to see limited.While instability and war represent the darkest outcomes for a botched succession process, modernization and economic reform are possible positive outcomes, panelists said. China, which provides a large percentage of the country’s power and food, is hopeful that the north will undergo a Chinese-style economic awakening, Saich said. Russia is also hoping to see economic reforms, Kramer said.All that is in the hands of the new regime, which Eckert said may have been better prepared for succession than some give it credit for. One fear voiced about the accession of Kim Jong-un to power is that he has not had a lot of time to consolidate his own clout, unlike his father, who was groomed as a successor to the nation’s founder, Kim Il-sung, for 20 years.Though the process would have been invisible to outsiders, Eckert said that Kim Jong-il’s 2007 stroke may have sounded a warning that put preparations for succession in motion, meaning that Kim Jong-un may have a stronger grasp on power than it might appear.“The rapidity with which the North Korean state has embraced Kim Jong-un suggests plans have been in place for some time,” Eckert said.Eckert, who said the succession process seems to be proceeding well so far, also said that North Korea’s elite, who are taken care of by the regime, have a lot to lose if the government destabilizes.Though it has communist roots and has been run as a dictatorship, North Korea may be best understood if thought of as a monarchy, Eckert said. A member of the Kim family has ruled the nation since its founding in 1948. In monarchical succession, if the bloodlines are right, it doesn’t matter how old the new ruler is or what he looks like. If the ruler is considered too young, a regent can be appointed to help run things. In North Korea’s case, Kim Jong-un, who is not yet 30, has a prominent uncle to help him.Eckert warned, however, that North Korea remains such a closed country that all prognostications need to be taken with a large grain of salt.“There’s a good need for some modesty and humility about what we can say,” Eckert said.last_img read more

Fight fire ants

first_imgBy Faith PeppersUniversity of GeorgiaFootball games aren’t the only struggles cranking up on grass battlefields now. University of Georgia experts say fall is an ideal time to fight fire ants, too.”It’s appropriate to treat for fire ants anytime that they’re active,” said Dan Suiter, an entomologist with the UGA College of Agricultural and Environmental Sciences. “They’re active in warm months.”Since it stays warm well into the fall in the South, keep up the fight.”You hear about fall treatments sometimes in light of baiting programs,” Suiter said. “Many of the baits registered for fire ant control are very slow-acting growth regulators. It may take a half year or more to eliminate the colonies. So, the thinking is to bait in the fall, and the next spring the ants will not return.”New weaponsRed imported fire ants first made an appearance in Georgia in the early 1950s. By 1987 they had spread to 143 of 159 counties. Today the entire state is infested, as is much of the East Coast to southern Virginia.”While the basic biology of fire ants hasn’t changed, there have been some advances in control techniques and materials,” said UGA entomologist Will Hudson.”Baits remain the best options for large areas (more than 1 acre or so),” he said.Many brands fall into two basic groups: those with active ingredients that are toxic to the ants (like Amdro) and those that have as active ingredients insect growth regulators that sterilize the queen and stop development of the immature ants in the colony.”Baits work by taking advantage of the ants’ behavior,” Hudson explained, “so we can apply a small amount (1 to 1.5 pounds per acre) of material and let the workers take it back to the mound and feed it to the colony.”No mounds v. no antsApplied every six months, they often carry a guarantee of “no mounds” if applied correctly. Not “no ants,” but “no mounds.””As it happens, it takes about six months for a colony to grow from the founding queen to a size where there are enough workers to build the characteristic mound,” he said, “and the baits are good at breaking the cycle. There will, however, be ants there between applications, just not all that many.”Bait treatments generally cost $20-30 per acre.For smaller areas, or where you need zero ants, Hudson recommends a broadcast application of a contact insecticide.”The best of these include fipronil products such as Over’n’Out for homeowners or those with pyrethroids as active ingredients,” he said.Pyrethroids are active ingredients ending in -thrin such as bifenthrin, permethrin, cypermethrin or cyfluthrin.”There are lots of these on the shelves, as they’re all off patent now,” Hudson said.”Fipronil will usually give a season of ‘no ants,'” he said. “The pyrethroids are less long-lasting, but will give 1 to 3 or even 4 months of control. After that, the cycle starts over if the ants are flying (almost all year in south Georgia and April through October in Atlanta).”Costs range from less than $50 per acre for pyrethroids to more than $150 per acre for fipronil. “But, if your yard is 5,000 square feet, they aren’t that expensive,” Hudson said.A newcomer to the fire ant control market is indoxacarb, which is sold as Advion for commercial use and in the Spectracide line for homeowners. “It’s a bait, but instead of weeks to see a reduction in ants, they start to disappear in a couple of days. It’s still a ‘no mounds’ type, but fast,” Hudson said.last_img read more

Forage Management

first_imgAccording to Lisa Baxter, University of Georgia Cooperative Extension’s newest forage agronomist, an unusually wet winter will cause problems with summer forage crop quality in Georgia.Baxter, who started work on the UGA Tifton campus on March 1, expects to field her share of questions about forage management and quality concerns from Georgia producers this year.“This year, with all the rain we’ve had, we’re going to see fertility issues, weeds and potentially diseases like we haven’t seen in a long time. It’s something that we’re gearing up and preparing for,” Baxter said.Many of the issues facing forage producers will be discussed in greater detail at this year’s Georgia Forages Conference, held in conjunction with the Georgia Cattlemen’s Association Convention in Perry, Georgia, on April 4.As an Extension forage agronomist, Baxter serves as the southern counterpart to UGA Extension forage agronomist Dennis Hancock, who is based in Athens, Georgia, and serves farmers in the northern part of Georgia. Baxter will serve south Georgia’s farmers with concerns ranging from pests and diseases to forage management and grazing issues.Because of south Georgia’s warmer climate and different soil types, the crops grown in Tifton, Georgia, and other south Georgia areas vary from what’s produced in more northern locations such as Blairsville, Georgia. For example, Bahiagrass is a long-lived perennial grass that’s grown in south Georgia but not north Georgia. Bermudagrass is used more extensively in the southern part of the state than in north Georgia.Baxter believes that these warm-season crops will be impacted significantly by the excess rain experienced this winter.“When Bermudagrass starts greening up, it’s may be struggling this year. We have already seen reports of warm-season weed species. It’s going to be competing with crabgrass and warm-season broadleaf species, and ryegrass is going to be hanging around with these cool, cloudy conditions. We are preparing for anything in the textbook that could potentially hit us this year,” Baxter said.One problem producers have had in managing their crops this year was the use of preemergence herbicides. To combat the weed pressure in most fields, producers normally apply chemical treatments, but it was too wet for many farmers to get in the fields during the winter. If the treatments were not applied at the right time, weed pressure will be high this summer.Baxter also expects the Bermudagrass stem maggot to be a problem again this year. Since first being discovered in 2010 in southern Georgia, the pest has damaged Bermudagrass hayfields and pastures throughout the Southeast U.S. If left untreated, Bermudagrass stem maggots can cause farmers to lose up to 80 percent of their yield during the peak season, which runs from late July to early September.Although farmers can’t fully control the pest, taking an integrated biological, cultural, physical and chemical approach will reduce economic damage.Baxter hopes to coordinate research projects in her new role so that growers will have additional options to combat this pest. “It’s a major problem throughout the Southeast. So much of our state’s hay production is Bermudagrass, so it hits Georgia a lot harder than other areas,” Baxter said.She also plans to continue several collaborative research projects, including those with Jennifer Tucker, a UGA Extension beef nutrition and forage management specialist; Bill Anderson, U.S. Department of Agriculture plant research geneticist; Tim Grey, UGA weed scientist; and Brian Schwartz, UGA Extension turfgrass breeder.For more information about Bermudagrass stem maggots, see UGA Extension Bulletin 1484, “Managing Bermudagrass Stem Maggots,” at more information about forages, visit read more

NFL owners approve diversity measure and potential play-off expansion | NFL News

‘Stop blaming us’: Surabaya mayor kneels down and cries over rising case number

first_imgThe doctor said that the hospital was overwhelmed with patients while also highlighting that there were still many residents of Surabaya who ignored the required health protocol to prevent further transmission of the highly infectious virus.The statement led to a temporary halt of the meeting as Risma started to kneel down and cry.“If you blame us [Surabaya administration], I won’t take it. We can’t even enter the hospital,” she said in tears as reported by argued that her office faced hurdles in reaching out to the hospital even when it tried to offer aid, without explaining the details. She also said that her administration had undertaken various efforts to control the spread of the coronavirus. Surabaya Mayor Tri Rismaharini knelt down on the ground and broke into tears as she held a meeting with doctors and hospital directors in Surabaya amid the spike of COVID-19 cases in East Java’s capital city, which has become Indonesia’s epicenter of the outbreak.Risma, as the mayor is affectionately known, was holding a meeting with the Indonesian Medical Association (IDI) and local authorities to discuss COVID-19 management at the Surabaya City Hall on Monday.In the video, which went viral shortly after the meeting, the mayor, known as Risma, was seen kneeling down, crying and apologizing after a pulmonologist from Dr. Soetomo Hospital in Surabaya shared in the meeting that the hospital was overloaded with COVID-19 patients. “Please don’t keep blaming us,” she said while crying.Read also: ‘COVID-19 is real’: Virus ravages family in Indonesia’s second-largest cityEast Java is currently Indonesia’s COVID-19 epicenter with a tally of 11,805 confirmed cases as of Monday, surpassing the capital city of Jakarta that has recorded 11,114 cases.Based on the East Java COVID-19 task force report on Sunday, Surabaya recorded half of the case of the province with 5,510 cases and 418 fatalities.Despite the worsening situation of the pandemic in the region, the Surabaya mayor has been long caught in the ongoing feud with the East Java Governor Khofifah Indar Parawansa over how to handle the pandemic in the region. An official at the East Java COVID-19 task force suggested that the city reinstate the large-scale social restrictions (PSBB) in the wake of soaring new cases. However, Risma said PSBB reinstatement was not in her administration’s plan for the time being as she would shift the focus to more testing and shutting down markets of shopping centers if positive cases were found, claiming that the numbers showed ‘downward trend’.
