The 800 year long ion record from the Lomonosovfonna (Svalbard) ice core

first_imgWe present a high-resolution record of water-soluble ion chemistry from a 121 m ice core spanning about 800 years. The core is well dated to 2/3 depth using cycle counting and reference horizons and a simple but close fitting model for the lower 1/3 of the core. This core suffers from modest seasonal melt, and so we present concentration data in decadal running means to minimize percolation effects. Sea-salt ions (Na+, Cl−, Mg2+, and K+) account for more than 70% of all ions. In general, sea-salt ion concentrations are rather variable and have no clear association with climatic variations. Sulfate, with 74% being from non-sea-salt sources, has higher concentrations than seen on Vestfonna ice cap but lower than in Ny-Ålesund aerosols, suggesting central Spitsbergen receives more marine (westerly) air masses than Ny-Ålesund but more sulfate enriched (easterly) air masses than Nordaustlandet. Clear anthropogenic impacts are found for sulfate, nitrate, and ammonium (and probably excess chloride) after the mid twentieth century, with sulfate showing a significant rise by the end of the nineteenth century. Sulfate and methanesulfonate concentrations correlate well during the twentieth century, and it is clear that most of the preindustrial sulfate is of biogenic origin. Terrestrial component (Ca2+) has the highest concentrations in the coldest part of the Little Ice Age, suggesting more windy conditions, transporting local terrestrial dust to the ice cap. All ion concentrations decrease at the end of the twentieth century, which reflects loss of ions by runoff, with non-sea-salt magnesium being particularly sensitive to melting.last_img read more

US Navy Growler flies on 100-percent biofuel

first_img View post tag: US Navy Share this article September 19, 2016 Back to overview,Home naval-today US Navy Growler flies on 100-percent biofuel View post tag: Biofuel US Navy Growler flies on 100-percent biofuel Authorities View post tag: EA-18G U.S. Navy’s EA-18G “Green Growler” completed flight testing of a 100-percent advanced biofuel at Naval Air Station Patuxent River, Maryland, in early September. “From takeoff to landing, you couldn’t tell any difference,” said Lt. Cmdr. Bradley Fairfax, project officer and test pilot with Air Test and Evaluation Squadron (VX) 23, after the first test flight Sept. 1. “The information presented to us in the airplane is pretty simplified but, as far as I could tell, the aircraft flew completely the same as [petroleum-based] JP-5 for the whole flight.”Using the Naval Air Warfare Center Aircraft Division’s (NAWCAD) Real-time Telemetry Processing System (RTPS) at the Atlantic Test Ranges, flight test engineer Mary Picard monitored the ground and test flights and confirmed Fairfax’s observations. “What we have seen is that the 100-percent bio-JP-5 appears to be basically transparent. It looks just like petroleum JP-5 in the airplane. So far, everything looks good and we haven’t noticed a difference.”And that’s the technical premise of the Navy’s alternative fuels test and qualification program: the JP-5 produced from alternative sources must be invisible to the user, said Rick Kamin, energy and fuels lead for Naval Air Systems Command (NAVAIR). Kamin also leads the alternative fuel test and qualification program for the Navy.The catalytic hydrothermal conversion-to-jet (CHCJ) process 100-percent alternative fuel performed as expected during a ground test Aug. 30 at NAWCAD’s Aircraft Test and Evaluation Facility (ATEF), followed by the first test flight Sept. 1, Rick Kamin, energy and fuels lead for Naval Air Systems Command (NAVAIR), said.The fuels program supports SECNAV’s operational energy goal to increase the use of alternative fuels afloat by 2020.“As the owner of the JP-5 aviation jet fuel specification, our job at NAVAIR is to make sure that whatever source our JP-5 is made from, we know it will work in our aircraft,” said Kamin.“This is the first time we’ve looked at a process that can produce a fuel with all the properties and chemistry of JP-5 jet fuel without having to blend with petroleum based JP-5,” said Kamin.CHCJ, the 100-percent drop-in renewable jet fuel that was tested, is produced by Florida-based Applied Research Associates (ARA) and Chevron Lummus Global. ARA’s process uses the same feedstocks as the Hydroprocessed Esters and Fatty Acids (HEFA) 50-percent advanced biofuel blend previously approved by the Navy, but goes through a conversion process that provides a fully synthetic fuel that does not need to be blended, Kamin said.The fuels team has evaluated five alternative sources for JP-5 and four F-76 sources since SECNAV kicked-off the program in 2009. The team, however, was already researching advanced biofuels in response to interest from the U.S. Air Force and the commercial airline industry in 2008.last_img read more

HMS St Albans escorts Russian frigate through the Channel

first_img Royal Navy frigate escorts Russian frigate through the English Channel Authorities A Royal Navy frigate on fleet escort duty followed a Russian frigate as it passed through the North Sea and areas of UK interest on Christmas Day.HMS St Albans, a Portsmouth-based Type 23 frigate, was called upon to sail on December 23 and keep watch on the new Russian frigate Admiral Gorshkov as it passed close to UK territorial waters.HMS St Albans remained at sea on Christmas Day to monitor the Russian frigate, keeping track of its activity in areas of national interest.According to the Royal Navy, St Albans will return to Portsmouth on December 26 [Boxing Day] and remain ready for very short notice tasking over the holiday period.UK defense secretary Gavin Williamson said: “I will not hesitate in defending our waters or tolerate any form of aggression.“Britain will never be intimidated when it comes to protecting our country, our people, and our national interests.”The festive season has seen an upsurge in Russian units transiting UK waters. HMS Tyne was also called to escort a different vessel, a Russian intelligence-gathering ship, through the North Sea and the English Channel on Christmas Eve, the navy said.A Wildcat helicopter from 815 Naval Air Squadron, based at RNAS Yeovilton, was then dispatched to monitor two further Russian vessels.“My ship’s company take great pride in serving Great Britain and the role they play dealing with both the routine and unexpected,” Commander Chris Ansell, the commanding officer of HMS St Albans, said. “Missing parts of Christmas and New Year with our families is never easy, but it is absolutely required as part of our duty to keep Britain safe all year round.”The 190-strong ship’s company of HMS St Albans join more than 4,000 sailors and Royal Marines who are deployed across the globe or on heightened readiness to respond to anything that may come their way.

Phraeda’s Love

first_imgSeduction, suicide, and sadism: based on a Greek tragedy, Phaedra’s Love has been updated to depict a disturbingly dysfunctional family. Phaedra becomes obsessed by her desire for her stepson Hippolytus who is a selfish, unfeeling lothario and the exboyfriend of Phaedra’s daughter. Phaedra’s Love does possess Sarah Kane’s “trademark ultra-violence” with the play starting as an uncomfortably intimate drama and moving through incest, rape, imprisonment and rebellion, to a bloodbath resulting in the death and destruction of a Greek royal family. However, the director believes Phaedra’s Love to be Kane’s “most accessible play” though some areas regarding sexual acts and mutilation seem uncomfortably drawn out. As disturbing as Phaedra’s Love is at points, it is well-directed by Lucy Burns. The destructive mood is conveyed well by a set which has waste emerging from wounds in the black walls. The acting is of high quality. Hippolytus is well acted by Philip Contos, who makes himself hateful in his selfish boredom. Matthew Trueman and Kate Donald deliver strong performances, and Valentina Ceschi portrays Phaedra’s varying moods and emotions powerfully. Worth seeing, this psychological roller coaster will send you reeling. Be warned, it is not for the faint of stomach, and if you plan to sit near the front, wear clothes you do not mind staining with the remains of the dead.ARCHIVE: 3rd week TT 2004last_img read more

Notre Dame professor publishes study with new insights on fatherhood

first_imgCourtesy of r A father from the BaYaka tribe poses for a photo with his young sonin the northern Republic of Congo, where Boyette did his field work.Boyette did his dissertation research in a remote region in northern Republic of the Congo —accessible by a weeklong journey from the capital city of Brazzaville. There he studied the BaYaka and Bondongo people who live a very different lifestyle than one we’re used to. Although located in the same village, the two tribes have their own distinct cultures. The BaYaka people are a more egalitarian society, focused on cooperative living, whereas the Bondongo people are fisher-farmers whose society is hierarchical and status-based.Boyette noted that the differences between these two communities who live in such close conjunction is really what drew their study to this remote corner of the world.“Our interest was to work with both groups and try to understand differences and look to see if there were differences in fathering that are related to cultural differences, including things like variation in the family systems and what fathers do in the community,” Boyette said.They hypothesized that the testosterone levels of the BaYaka men and Bondongo men were different. Testosterone, a hormone which has been shown to decrease in men when entering fatherhood in some cultural settings, can be associated with physical strength and aggression. Gettler’s team hypothesized that since the BaYaka fathers place more emphasis on community and generosity, their testosterone levels will be lower than the Bondongo fathers, who are valued more for their strength and being a good resource provider.When the researches had an opportunity to collaborate via funding from the Jacobs Foundation, Boyette said that he and Gettler jumped at the chance.“[The Jacobs Foundation] offered us this opportunity to apply for funding to work on projects together,” Boyette said. “It was a really fantastic opportunity and Lee and I right away saw a really good opportunity to collaborate because we both had different skill sets that we recognized would work well together.”Before the two could conduct any formal research, they had to connect with the communities and get settled.“The first summer of our grant, [Boyette] went to field site and just basically was hanging out to gain trust with the communities to talk to them about ‘Here’s what we’re interested in, we’re interested in learning about your communities and here’s what we would do,’” Gettler said. “[Boyette was] getting permission from the communities, particularly the elders and the leadership councils in the community, to make sure that they were that it was acceptable to them, ethically, that we do this work.”Boyette said that the work was challenging, and it would not have been possible without the help of others who blazed the trail for him.Another challenge faced by the team was how to transport their materials. Gettler explained that this was an especially difficult project because they needed to transport large liquid nitrogen jugs to store saliva samples containing information about testosterone from the BaYaka and Bondongo men.“If we look at testosterone in saliva, it correlates really strongly to what is circulating in the blood in the body, but it’s obviously much less invasive than collecting blood so that’s the benefit,” Gettler mentioned. “Part of the reason that there are few studies in this kind of relatively remote setting is because of the challenges of dealing with the biological markers.”Boyette explained that they had to modify their travel plans in order to transport the materials to the remote communities because the canisters of liquid nitrogen need to be closely monitored at all times to prevent spillage.The researchers also struggled with the problem of how to quantify how the different cultures viewed fatherhood and how to decide who were the “good fathers.”Gettler explained that the team conducted a series of long interviews with the villagers to get a sense of the values that were sought after in a good father.“[Boyette and his team] spent a lot of time doing semi-structured qualitative interviews—we’d call that data ethnography,” Gettler said. “Our real goal was to try to understand how these communities are defining what a good father is and then can we find a way to operationalize that to get at whether good fathers, based on local values, have healthier kids.”Once they had sorted out the cultural ideas of fatherhood, the researchers had each respective father rank each other on the main values pointed out by each community. The questions that the fathers ranked each other by varied between the BaYaka and Bondongo groups: The BaYaka cultural ranked good fathers based on how they shared resources, how hard they worked, whether they had any spousal arguments, whether their children were healthy and if they contributed to community teaching. On the other hand, the Bondongo people ranked good fathers based on fishing/hunting abilities, how big their gardens were, if they traveled to get commercial goods for the community, if they had healthy children and if they contributed to social education.Boyette said that the different questions actually revealed a lot about the communities.  He explained that they found that the Bondongo fathers were actually sorted into two groups: one of the groups of fathers focused more on the hard, laborious chores of fishing and hunting, and the other group focused on the teaching of children and staying closer to the community. As Boyette and Gettler expected, the group of Bondongo fathers that focused on the strength intensive tasks had higher levels of testosterone than the group that focused more on the children. With the BaYaka tribe who are more focused on cooperative communities, the researched noted lower levels of testosterone in men who were ranked as better fathers.The team also noted a correlation between testosterone levels and martial arguments. They found that fathers in both communities who were rated as having more martial conflicts had higher testosterone levels.Gettler and Boyette both agree that their study has impacts outside the remote village in the Republic of Congo. Boyette said that he believes this study shows us that there is not just one way to be a great father.“There’s not one good way that men should be contributing to their families and we have to recognize that men see themselves as coming from particular different cultural backgrounds and that these may also suit their biology better or are promoted by their biology in different ways,” Boyette said. “We should be able to welcome various ways of being fathers and different ways of contributing to the child development and supporting.Tags: anthropology, Fatherhood, Jacobs Foundation Recently published in Nature Magazine’s Scientific Reports, Dr. Lee Gettler, an associate professor of anthropology at Notre Dame, has completed a new study which links testosterone levels in fathers with their broader cultural settings.Gettler said that he became interested in his research when he met Dr. Adam Boyette, who is now a senior researcher at the Max Planck Institute for Evolutionary Anthropology, at a conference put on by the Jacobs Foundation.“[The Jacobs Foundation] put together a conference that was specifically bringing together a really large group of scholars who specifically studied fathers from diverse perspectives —psychology, sociology, neuroscience, anthropology — to try to get all these people in the same room to talk about how we can begin to kind of best understand the way that fathers impact human children,” Gettler said.last_img read more

Will Hamilton’s Jordan Fisher Play Benny in the In the Heights Movie?

first_img from $149.00 Jordan Fisher Tomorrow there’ll be more of us, telling the story of tonight the Heights! Hamilton mastermind Lin-Manuel Miranda wants Grease: Live heartthrob and current Hamilton star Jordan Fisher to play Benny, the role originated by Tony nominee Christopher Jackson, in the film version of In the Heights. The certified genius recently sat down with The Huffington Post to discuss In the Heights’ tenth anniversary; the Tony-winning musical opened off-Broadway on February 8, 2007 before transferring to the Great White Way in 2008.“There’s certainly some incredible young Latino talent that were still babies when we were opening off-Broadway. But I hadn’t thought about it,” he told HuffPo. “I think Jordan Fisher would be a pretty good Benny. He’s playing Laurens for me on Broadway, and he’s a super-talented young man.”As previously reported, the Weinstein Company-produced big screen adaptation of Miranda’s musical is set to begin production in the spring. Also as reported, Fisher is scheduled to play his last Hamilton performance on March 5.As for whether or not Miranda will take his portrayal of Usnavi to the screen, the Oscar nominee said, “I don’t want to play the role if it feels like it’s not age-appropriate with the rest of the cast. But Chris Jackson and I can be in the background playing dominoes during ‘When You’re Home,’ and that would be f*ing great.”Spying Heights and Hamilton Broadway alums on the big screen sounds like our new favorite game. Here’s hoping we get to play it soon! In the meantime, check out Broadway.com’s One on One sesh with Fisher below.

Study shows rooftop solar pushing fossil fuels off of Australian electricity grid

first_imgStudy shows rooftop solar pushing fossil fuels off of Australian electricity grid FacebookTwitterLinkedInEmailPrint分享Renew Economy:Strong growth in rooftop solar installations has continued to push coal fired generation out of the Australian electricity market, a new audit of the National Electricity Market has shown.The latest edition of the National Energy Emissions Audit published by The Australia Institute found that the initial impact of disruptions caused by the Covid-19 pandemic has had a small impact on electricity consumption. At the same time, the continued strong growth in uptake of rooftop solar, which supplied more than 16 per cent of South Australia’s total electricity consumption over the last summer, and 7.7 per cent of Queensland’s consumption over the same period, has worked to drive fossil fuel generators out of the market.Analysis of the rooftop solar market has shown that 2019 was another record year for new installed capacity on homes and small businesses, with the accelerating pace of installations continuing for at least the first four months of 2020.To illustrate that growth, the audit showed the share of rooftop solar in total generation in South Australia has jumped from 10.1 per cent to its latest level of 16 per cent in the first quarter, while in Queensland it jumped from 5 per cent to 7.7 per cent.“Without rooftop solar, gas generation in South Australia would have had to supply 20 per cent more electricity in summer 2017-18 and 44 per cent more in summer 2019-20,” it says. Coal would have had to rise by 10 per cent last summer.Based on this strong growth, the National Energy Emissions Audit predicts that the annual share of renewable energy in Australia will top 25 per cent for the first time in the year to April 2020. This growth in rooftop solar, along with growth in generation from large-scale wind and solar projects, is succeeding at pushing coal fired generation out of the market. Over the 2020 Easter weekend, the share of electricity consumption in Australia’s main grid being supplied by renewable energy projects exceeded 50 per cent for the first time.[Michael Mazengarb]More: Record growth in rooftop solar pushing coal out of Australia marketlast_img read more

Berger demands data security accountability ahead of House Equifax hearing

first_imgNAFCU President and CEO Dan Berger yesterday urged congressional action to ensure that credit unions do not bear the cost of negligent data practices by entities like Equifax.Berger made his call for increased data security responsibility in a letter sent to House Energy and Commerce Subcommittee Chairman Bob Latta, R-Ohio, and Subcommittee Ranking Member Jan Schakowsky, D-Ill., ahead of the Subcommittee on Digital Commerce and Consumer Protection’s hearing today on the Equifax data breach. The hearing begins at 10 a.m. Eastern.In the letter, Berger said the frequency with which data breaches occur is “unacceptable,” as these events “have become a constant concern of the American people.”Berger urged that all entities that handle personal financial data be subject to the same standards credit unions and other financial depository institutions follow under the Gramm-Leach-Bliley Act (GLBA), and he specifically called for credit rating agencies already subject to the GLBA, like Equifax, to undergo the same examinations for compliance as credit unions. 11SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr continue reading »last_img read more
