Differential scanning calorimetry studies on an Antarctic nematode (Panagrolaimus davidi) which survives intracellular freezing

first_imgDifferential scanning calorimetry was used to characterize thermal events associated with freezing and melting of suspensions and extracts of Panagrolaimus davidi, an Antarctic nematode which can survive intracellular freezing. Nematode suspensions produced a single freezing exotherm with a shoulder on the peak representing the freezing of the nematodes. A shoulder on the peak of melting endotherms indicates the melting of the nematodes and of the water surrounding them. Exotherms were also detected from individual nematodes mounted in liquid paraffin. The freezing of nematodes was very rapid and in marked contrast to that of freezing-tolerant insects and vertebrates, which take hours or days to freeze. Eighty-two percent of the nematodes’ body water froze. High levels of survival were obtained in nematodes exposed to temperatures down to -40 degrees C. No additional thermal events were observed after the freezing event and before the melting of samples cooled to -40 degrees C, indicating no changes in the proportion of body water frozen. Ice nucleating activity is present in nematode suspensions but not in supernatants from nematode extracts. No thermal hysteresis activity was detected in nematode extracts.last_img read more

Notre Dame looks to start stadium construction in 2014

first_imgThe University is hoping to begin massive construction on Notre Dame Stadium after the conclusion of the 2014 football season, University President Fr. John Jenkins said in an interview with The Observer.The Notre Dame Board of Trustees has endorsed a plan to build three buildings totaling 750,000 square feet that will surround the Stadium. The project, titled the “Campus Crossroads Project,” is expected to cost $400 million, Jenkins said. Courtesy of the University of Notre Dame Pending approval from the Board of Trustees, the Campus Crossroads Project will add a new student center, a digital media studio and academic offices to the existing StadiumWhile gaining the Board’s endorsement is a big step forward for the University, Jenkins said Notre Dame would still need to raise the funds for the project. Notre Dame’s policy to have 100 percent of the funding promised and 50 percent in hand before construction begins.“We need to find benefactors who will support this project because we won’t go ahead unless the funding is in place,” Jenkins said. “So, it’s contingent on that. We’re optimistic about getting that done. … But until we get that, we can’t say definitely, we’re doing it.”Jenkins said about half of the funding would come from benefactors and the rest would come from various sources, including revenue from football tickets. The project would not be funded by revenue from existing seating, a release from the University said.Student ticket prices would not be directly influenced due to the new construction, instead the new premium seating (3,000 to 4,000 additional club seats) would help fund the project, Jenkins said.According to Jenkins, the project is expected to take 33 months from start to finish but the Irish will still be playing all scheduled home games in the Stadium. Ideally, Jenkins said the University would make the decision to go ahead with the project in August and start building after Notre Dame’s home finale against Louisville in November.Commencement ceremonies, which are typically held in Notre Dame Stadium, may have to be moved elsewhere during the 33-month construction, possibly the Joyce Center, Jenkins said.“I don’t want to say because it’s not definite yet,” Jenkins said. “We’re going to play football there, but there may be a problem with graduation so we’ll have to gather people together and see what we need to do.”Jenkins said the University would need South Bend’s approval but that he expects they won’t take exception to it.The University expects to employ all local construction trades locally, spokesperson Paul Browne said. Notre Dame could also contract some Chicago-area companies to help with construction.“The demand for skilled trades and crafts building will probably exhaust the local area and beyond,” Browne said. “But who the entities doing that, whether it’s Chicago or elsewhere, that hasn’t been decided yet.”Jenkins said Notre Dame would look first towards South Bend for construction companies.“I know primarily we are going to look [in South Bend], we want to give the opportunities for jobs to the local community,” Jenkins said. “I know we’ve worked with these companies before. My understanding is this project will just tap out all of the available resources, so I don’t know if we will need to go beyond that. We’re certainly going to start here.”Vice President of Student Affairs Erin Hoffmann Harding said the companies 360, Slam and Workshop Architects have been some of the firms Notre Dame has worked with so far.Last May, Notre Dame commissioned a feasibility study to decide if additional buildings were needed around the Stadium. Jenkins said the University had a concept that evolved over time.“What we had to do is ask ‘What are our needs?’” Jenkins said. “What are our needs for buildings? We had a strategic plan and each of the buildings we’re envisioning were part of that plan. They were envisioned as these were the things we need. We don’t know where it’s going to be. We don’t know the design. These are the facilities we need. So our question is ‘Could our needs fit this structure?’”Jenkins said the original plan was to have buildings on all four sides of Notre Dame Stadium but only ones on the east, south and west sides are in the plans. He said Hesburgh Library and “Touchdown Jesus” could have been kept visible with a building there but there simply was not a need for one.Tags: Board of Trustees, Campus Crossroads, Commencement, Erin Hoffmann Harding, football, Fr.

Series examines gender in theology

first_imgSaint Mary’s Theology on Fire series examined gender’s role in Christian theology with a discussion on “American Women and the Permanent Diaconate” facilitated by Katherine Harmon, a theology professor from Marian University.Harmon began the conversation by recalling a project given to her by a former professor at Notre Dame called “On the Archives.” She said the assignment was fairly open-ended and meant to delve into a particular subject of the student’s choice.Harmon said she researched the word “women” and soon came across “woman diaconates.”Harmon asked the event’s attendees if they could recall the role of a deacon. The audience said deacon’s responsibilities include teaching, reading and assisting with baptism.“The role of the deacon has to do with service,” Harmon said.Harmon listed statistics pertaining to the average American deacon, including level of education, age and marital status.“One-hundred percent of contemporary deacons are male,” she said.Harmon said the historically, this hegemony was not always the case. Harmon said various sources, like unclear passages from books in the Bible like Timothy and Romans, as well as letters from Church authority recognized the role of deaconesses.Given this public information, Harmon said she pondered why the idea of a woman in the role of deacon seem so foreign to Catholics today.“The issue, it seems, is dealing with the word ordination,” Harmon said. “If you took the present definition and tried to apply it to the past, these women were not ordained.”Harmon said although she was unaware of a specific modern-day movement to return women to the role of deaconess, she was personally motivated to share this information because it is the unknown truth.“To me, it is crucial to see that women were there and to see where they were. It is important to recognize the presence of women in history, especially in the liturgy,” Harmon said.Tags: theology on firelast_img read more

Peruvian Armed Forces Report Operations Against Organized Crime

first_imgBy Yolima Dussán/Diálogo November 16, 2020 In operations carried out September 8-21, the Peruvian Armed Forces dealt several blows to narcotrafficking and illegal mining.On September 21, thanks to intelligence gathered by an elite group of the Peruvian National Police, service members found 433 kilograms of cocaine buried in Huanta province, Ayacucho department, as reported by the Peruvian newspaper El Comercio.During a mega operation against illegal mining on September 8, Peruvian authorities seized and destroyed 30 engines like the one pictured, in La Pampa, Madre de Dios, Peru. (Photo: Peruvian Armed Forces Joint Command)The Peruvian Armed Forces Joint Command (CCFFAA, in Spanish) told the press that on September 17, the Amazon Operational Command detained four Colombian nationals who were carrying 11 kg of cocaine, military rifles, pistols, grenades, and ammunition. The operation took place in Loreto department, near the Colombian border, where the detainees were identified as members of the criminal group E-48, dissidents of the Revolutionary Armed Forces of Colombia (FARC, in Spanish).In another operation on September 13, the Apurímac, Ene, and Mantaro Rivers Valley (VRAEM, in Spanish) Special Command found a lab, where “law enforcement forces seized 200 kg of cocaine hydrochloride and 150 kg of liquid drugs,” according to a  press release. “In addition, about 3 tons of chemical precursors to manufacture drugs were found,” the CCFFAA said online. The operation took place in Huanta province, Ayacucho department.On September 9, police seized 231 kg of cocaine coming from the VRAEM that “were going to be shipped to Brazil and Bolivia by air, from a clandestine airstrip,” El Comercio reported. During the operation, eight adults and one minor were detained and three trucks that were used to move the drug were seized, the newspaper reported.Narcotrafficking seems to be growing in the region, according to a July 31, 2020 report from the White House Office of National Drug Control Policy indicating that, “Coca (the plant used to make cocaine) cultivation in Peru significantly increased to 72,000 hectares in 2019, with potential pure cocaine production of 705 metric tons.” In 2018, the number of cultivated hectares was 52,100, with a potential production of 505 tons, the report added.Regarding the Peruvian security forces’ operations against illegal mining, authorities found and destroyed 22 illegal mining campsites in just one day.On September 8, patrols comprising members of the Peruvian Armed Forces, the National Police, and the Office of the Attorney General specializing in the Environment conducted a mega operation in the Vuelta Grande and Laberinto sectors, in La Pampa, Madre de Dios region, the CCFFAA indicated.On site, authorities found 30 engines, 26 rafts, and 11,916 liters of fuel, among other equipment. All the material and equipment were destroyed, the CCFFAA added.La Pampa has become a large mining enclave as a result of the construction of the Brazil-Peru Interoceanic Highway, which opened in December 2010, according to the report Conversion of Forest Landscapes to Amazonian Wetlands by Gold Mining, published in February 2020 by the Center for Amazonian Scientific Innovation, a Peruvian NGO dedicated to environmental and social research in the Amazon. “Between 2016 and 2019, 5,377 water wells were polluted by minerals as a result of gold mining; about 28 percent of the area has been degraded by illegal mining,” the report says.last_img read more

Martinez proud of new Everton role

first_img The Spaniard has signed a four-year contract to take over from Manchester United-bound David Moyes, and while he sees similarities with his other jobs in football, he knows this one is different. “I know what it means to play for this club in terms of the amount of families (involved) and passion which comes across, so I understand how honoured I am to have this position,” said the 39-year-old, who left Wigan after four years. Press Association “I can’t describe it but when we (Wigan) played here in the quarter-final of the FA Cup (winning 3-0), there was a feeling that you can develop and know you belong and, funnily enough, now I can start exploring it and finding out what the fans want. “It is very important in modern football not to lose the real values in the modern game and it is important to understand the fans, and Everton have really strong football values with an incredible passion. “When I arrived at Goodison, I got that feeling right away. I know I can fit in quickly and feel part of it straight away.” Martinez is confident he can retain the club’s in-demand stars, like midfielder Marouane Fellaini and England left-back Leighton Baines, and fulfil a Champions League dream. “In the game when you are successful – and Everton were clearly successful last season – you will always get good performers who attract interest from other clubs,” he said. “That not only happens here, it happens at every football club in the land and abroad, so we’re not worried about that.” Kenwright has already promised to back his new manager as best he can financially this summer “I’ll give him a few quid to spend. The others are not for sale. We don’t want them to go, they have worked massively hard for this club,” he said. “Roberto doesn’t want them to go, he has all their numbers and he will be on the phone asking them not to go. Not one person has even half-indicated they want to go.” center_img New manager Roberto Martinez already feels at home at Everton and believes he is privileged to have the opportunity to take charge of the club.last_img read more

FH : Syracuse uses strong second half to advance to second round of NCAA tournament

first_img Facebook Twitter Google+ Ange Bradley said her Syracuse team showed early jitters in its first-round game against Richmond in the NCAA tournament.The SU head coach watched the Orange try to find its comfort zone as the Spiders fired six shots and challenged SU goalkeeper Leann  Stiver in a scoreless first half.‘In the first half we looked apprehensive and held back,’ Bradley said in a phone interview. ‘It took us a while to figure out their pressing patterns that they did and then once we did that we got our confidence and we did well.’No. 3 Syracuse (19-3, 5-1 Big East) found its confidence and used two goals from Heather Susek in the second half to earn a 2-0 victory over the Spiders Saturday in front of 529 in College Park, Md. The Orange made defensive adjustments at halftime to counter Richmond’s effective pressing approach to advance to the second round of the tournament Sunday, where it will face No. 4 Maryland at 2 p.m.SU held off Richmond in the first half despite the Spiders holding a 6-3 shot advantage.AdvertisementThis is placeholder textRU senior forward Katelin Peterson launched four first-half shots, two of which tested SU junior goalkeeper Leann Stiver. Stiver made both saves to keep the Spider off the board.And at halftime, the Orange calmed down and made the necessary adjustments. Bradley said the backs reshaped different in the second half and the forwards — most notably Susek — made a concerted effort to link players in all three sections of the field.With those adjustments made, Syracuse created more scoring opportunities, and outshot Richmond 9-3 in the second half.Susek broke the scoreless tie in the 50th minute, off a pass from senior midfielder Martina Loncarica. And just five minutes later she struck again, this time with an assist from freshman forward Jordan Page.‘She just was one of those forwards that popped back into the hole and served to be a connector between the backs and the forwards,’ Bradley said. ‘So she really was the impetus for change in our second half.’Susek’s performance coupled with the stifling effort in net from Stiver led SU into the second round.Bradley said the Orange will use the time before Sunday’s game to rest up and prepare for the next step toward the team’s ultimate goal of winning a national championship.‘We’re taking care of our bodies right now, and getting ready,’ Bradley said. ‘We want to be national champions so we’ve got to win. That’s what our mindset is.’[email protected] Published on November 12, 2011 at 12:00 pm Contact Stephen: [email protected] | @Stephen_Bailey1center_img Commentslast_img read more
