Laboratory study of the migration of methane sulphonate in firn

Posted On May 9 2021 by

first_imgTwo 10cm lengths of firn core from the Dyer Plateau (700° 3l’S, 65°0l’W), Antarctic Peninsula, were used to carry out a laboratory experiment to investigate the migration of methane sulphonate, the anion of methane sulphonie acid (MSA), in natural fim. Each length was cut vertically into tour pieces, and a dopant solution containing Cl-, NO3,-, SO4 2, F and MSA pipetted onto the top of three sections, the fourth being kept as a blank. The doped sections were stored vertically, with the doped end uppermost, for R months at a range of temperatures (nominally -5°, -10° and -22°C) before subsampling at 1em resolution and analysis by ion chromatography. The two firn lengths were treated identically and the results were consistent. Profiles of the doped fim sections showed that Cl-, NO3,-, SO4 2, remained in the uppermost subsample, although the NO3 concentrations were variable compared to the blank. The yo profile shows slightly elevated concentrations in the second sample down compared to the blank, at temperatures of -l0°C and above. The MSA- showed higher concentrations in the second, third and fourth samples down at -10°C and above, which indicates that some percolated downwards from its original position at the top of the core. This experiment shows that MSA is mobile in warm fim even over a short period of time. We propose that the mechanism tor the mobility of MSA in natural fim is via liquid MSA drainage, though we cannot yet discount vapour phase transport.last_img read more

The only guy to do that recently has been Tom Brady, so I have such respect for both of those guys, I can’t pick against either one of them,” he said with a laugh.Manning did make a different prediction about Brady’s career no matter the outcome in Tampa.When asked if Brady should retire if he wins, Manning said, “I don’t think he will.”“It’s such an individual decision, nobody can make that decision for you, I have so much respect for Tom, the battles we had on the field, we formed a friendship off the field as well, always felt he brought out the best in me and vice versa for him,” he said. “I don’t think he will because it’s his first year in Tampa. He’s having a lot of fun, he’s happy, he’s joyous and I can see him doing it for a few more years no matter what happens on Super Bowl Sunday.”Another superstar athlete stressing the importance of happiness, and making an appearance by way of the new Michelob Ultra ad, will be Serena Williams.The 23-time Grand Slam winner, who is currently quarantining with her husband Alexis Ohanian and her daughter Olympia ahead of the Australian Open, told GMA that they are “a huge contribution” to her success.“For me, I win because I’m happy,” she said. “I love being around Olympia — It’s so good to have this experience with her, because I’ve gotten so much time to spend with her that I wouldn’t have had otherwise — so it’s been really good to have an opportunity to just be with her 24/7.”She and her 3-year-old have enjoyed time on the tennis court as well as exercising their imaginations.“We, like, make up things — l look at something and say, ‘oh, that’s a giraffe,’ or that we’ll go to the fake zoo. And my imagination has been pushed to its limits,” Williams said. “And so it’s kind of cool because I feel like I can be a kid again and have imagination.” Copyright © 2021, ABC Audio.

He’s put in the time, sacrificed, he’s formed a bond with his new teammates in a short period of time, in a pandemic offseason, so he’s earned the right to have his team in a Super Bowl in his hometown,” Manning said.He explained that this matchup will make for “a great Super Bowl.”“It’s kind of the new guard vs. the old school guard — Mahomes is just exciting to watch — a guy that plays with a lot of joy and that’s a big part of him playing so well. I can tell you those Chiefs are having a lot of fun,” Manning said. “But Tom is Tom, he’s been doing it for so long and there’s nothing he hasn’t seen before. So it’s going to be a battle of those two quarterbacks.” January 25, 2021 /Sports News – National Peyton Manning weighs in on Tom Brady, Patrick Mahomes Super Bowl matchupcenter_img Is Peyton happy because he wins, or does he win because he’s happy? pic.twitter.com/G1oqqQLcA2— Michelob ULTRA (@MichelobULTRA) January 24, 2021“When I look back on my football career, I felt our teams won a lot of games and I played my best games when I was happy. I had a lot of joy during my football career,” Manning told Good Morning America on Monday. “There’s the old saying, enjoy the journey not the destination. And when I think back on my memories during my 18 years of playing, I think about those plane rides with my teammates, I think about hanging around the locker room, laughing with each other, I think about taking the offensive linemen out to eat on Thursday nights, keeping them well-fed, maybe having a couple of cold beverages and that was well worth it.”He continued, “Those are some of my greatest takeaways. Those happy moments that I felt brought our team together and helped us win more games on Sunday and help us win a championship. And then of course you’ll have the happiness after, but I think you can certainly do both.”Manning, who retired in 2016 after leading his Denver Broncos to a Super Bowl title, said “I have no regrets. I left it all out there on the field. But I do miss my teammates.”Now one of his longtime competitors and close friends, Tom Brady, is headed to Super Bowl LV with Tampa Bay in his first year with the Buccaneers to face defending champion Patrick Mahomes and the Kansas City Chiefs.

Bolder energy policies needed to tackle climate emergency, warns IEA

Posted On May 7 2021 by

first_imgExisting energy policies will fall short of addressing future problemsThe IEA’s World Energy Outlook report published today assesses the current state of energy policies and industry developments around the world in the context of tackling climate change.It finds that if the stated policy intentions and targets of governments are carried out alongside existing measures, it will be the case in 2040 that “hundreds of millions of people still go without access to electricity, pollution-related premature deaths remain around today’s elevated levels, and carbon dioxide (CO2) emissions would lock in severe impacts from climate change”.In this scenario, energy demand is expected to increase by 1% annually to 2040, with low-carbon sources able to supply more than half of this growth, while oil demand flattens out in the 2030s and coal continues its steady decline.The US will account for 85% of global oil production through to 2030, and for 30% of predicted increases in gas output – overtaking Russia in production of the combined fossil fuels by 2025, according to the IEA. The IEA says more needs to be done to reduce emissions from the energy sector if claimte goals are to be achieved Current energy policies set in motion by governments around the world are “well off track” from achieving a secure and stable energy future, according to the International Energy Agency (IEA).Energy-related greenhouse gas emissions hit a “historic high” in 2018, according to the watchdog – revealing the depth of the disparity between demand for climate action and the persistence of a “stubbornly high” reliance on fossil fuels.And with these emissions expected to continue beyond 2040 – albeit at a slower rate than now – existing momentum behind clean energy will be rendered “insufficient” in the effort to offset the effects of an expanding economy and population.IEA executive director Dr Fatih Birol said: “The world urgently needs to put a laser-like focus on bringing down global emissions.“This calls for a grand coalition encompassing governments, investors, companies and everyone else who is committed to tackling climate change.”If global policy ambitions are carried out as currently stated, the IEA warns that the world will “fall far short” of its shared sustainability goals as identified by the Paris Agreement.Growing risks associated with cybersecurity and extreme weather pose additional threats to international energy security, while a slowdown in energy efficiency improvement is proving an impediment to change in the electricity sector at a pace required to meet climate targets. IEA sets out a more ambitious ‘sustainable development’ scenarioGiven the expected shortfalls of current efforts to address the climate emergency through decarbonisation of the energy system, the watchdog outlines its vision for a “sustainable development” scenario that is fully aligned with the goals of the Paris Agreement.For this model to be made a reality, the IEA says “rapid and widespread changes across all parts of the energy system” will be required, alongside “sharp” emission cuts which can be made with new fuels and technology.Renewable forms of electricity generation will play an important role in tackling climate changeDr Birol adds: “What comes through with crystal clarity is there is no single or simple solution to transforming global energy systems – many technologies and fuels have a part to play across all sectors of the economy.“For this to happen, we need strong leadership from policymakers, as governments hold the clearest responsibility to act and have the greatest scope to shape the future.” The International Energy Agency has called for a “grand coalition” of governments and investors to implement the widespread and rapid changes needed to adequately decarbonise global energy infrastructure Energy efficiency must improve to meet climate targetsIt will also require more rapid improvements in energy efficiency – something that can have a significant influence over global efforts to reach the sustainable model presented by the watchdog.In 2018, “global primary energy intensity”, a key metric used to observe how heavily the world’s economic activity uses energy, declined for the third year in a row – up by just 1.2% during the year.The IEA has set a target of a 3% annual improvement, which it believes is necessary to meet Paris Agreement targets.“The historic slowdown in energy efficiency in 2018 – the lowest rate of improvement since the start of the decade – calls for bold action by policymakers and investors,” said Dr Birol.“We can improve energy efficiency by 3% per year simply through the use of existing technologies and cost-effective investments.“There is no excuse for inaction – ambitious policies need to be put in place to spur investment and put the necessary technologies to work on a global scale.”last_img read more


Purplebricks share price jumps 6% after bank’s positive rating

The fund currently stands at £6,085 with five weeks to go to reach to its target total. Purplebricks share price berenger October 13, 2017Nigel LewisWhat’s your opinion?

The information is obtained from both the assets it controls and the networks it manages, and, based on that situational awareness, for conducting operations such as counter-piracy Operation OCEAN SHIELD, counter-terrorism Operation ACTIVE ENDEAVOUR, and the various activities carried out by the four Standing Naval Forces.He attended the daily operations brief and met with MARCOM’s Deputy Commander, Vice Admiral Bruno Paulmier, before sitting down for a roundtable briefing and discussion with MARCOM’s five deputy chiefs of staffs. He concluded his visit to MARCOM with a visit to the NATO Shipping Centre, which is MARCOM’s link to the merchant shipping industry.Vice Admiral Johnstone said: “I warmly welcome Major General Blotz’s visit to MARCOM today. As the principle maritime advisor to the Alliance, we embrace the opportunity to discuss maritime elements of the Readiness Action Plan and the operationalization of the Alliance Maritime Strategy with our distinguished NATO Headquarters colleague.”Major General Blotz has served in the German Army since 1975, including operations in the Balkans and Afghanistan. As IMS Director of Operations, Major General Blotz is responsible for supporting the Military Committee with regard to NATO operations, and reports to the Director General of IMS.center_img View post tag: NATO View post tag: MARCOM Share this articlelast_img read more


Winter’s Last Gasp?

Posted On May 2 2021 by

first_imgFriday’s Winter StormAfter a nice stretch of weather, winter is making a return in what could be its final act. Strong NW winds with gusts to 40 mph is ushering in cold air and temperatures will drop into the 20s tonight so bundle up.A colder day for Thursday but less wind! Highs will only make it into the 30s. Clouds will increase ahead of the next storm system that will bring a little snow (and rain) our way. The low pressure system will move off the Carolinas late Thursday and intensify offshore Friday morning. Snow will move into the area late Thursday night into the overnight hours. Snow is expected to mix or change to rain (depending on exact track) Friday morning and winds will increase once again with gusts over 30 mph but this time winds will be blowing in from the northeast. Regardless of any mixing, snow accumulations are expected to be light as temperatures rise above freezing during the day, keeping slushy and wet (Less than 2”).Once this storm departs, chilly air remains through the weekend. Overall the weekend will be dry except Saturday night when a quick clipper swings through with a chance of a rain and/or snow shower.Next week a spring surge! Strong High Pressure will build offshore pushing temperatures into the 60s by midweek.last_img read more


Up from the ruins, slowly

Posted On Mar 1 2021 by

first_imgJoyce Klein Rosenthal, an assistant professor at the Graduate School of Design and an instructor in the School’s Risk and Resilience Master in Design concentration, spoke to the Gazette about lessons from past disasters and possible first steps toward rebuilding following the devastation of last Monday’s massive tornado in Moore, Okla.GAZETTE: After a natural disaster like the tornado that hit Moore, how soon should officials start planning for rebuilding?ROSENTHAL: It’s hard to pin down, it can be weeks or months, but you have this recovery period where people lost homes and are finding a place to live or are just trying to get in touch with loved ones and let everybody know they’re OK.After Katrina, there were some urban planners who came in a week or two afterward, saying, “OK, let’s talk about rebuilding,” and it was really too early.When you do come into this recovery phase, though, there are some precedents that are outstanding. You may remember a couple of years ago, Greensburg, Kan., was virtually wiped off the map by a devastating EF5 tornado. It destroyed homes and businesses, but the whole community came back together and worked with a creative architect, Bob Berkebile, who’s been one of the pioneers of green design. He worked with Greensburg to design better, “to build back better.”I’m an urban planner who’s really interested in process and that’s why I’m interested in Greensburg. Because it was very much community-based, with multiple charrettes and residents deciding, “OK we have the opportunity to rebuild our whole town, how should we do it?”GAZETTE: What was good from a planning standpoint about what happened in Greensburg?ROSENTHAL: When it was the right time — and certainly the week after may not be the right time — but when it was the right time they sat down and had community-based meetings and charrettes and asked, “OK, how are we going to rebuild?” There were a lot of different types of buildings destroyed — schools, businesses, and homes. They did a very green design, but you can also ask questions like, “Will we require that every home have an above-ground, concrete-lined, very heavy-duty shelter?” They really went through an intensive process of public deliberation.GAZETTE: You teach courses in the risk and resilience concentration. Can you talk a bit about what a resilient city is?ROSENTHAL: Resilience is a concept with a long history in ecology. Its specific meaning is when an ecosystem is disturbed, it can reach equilibrium again, though perhaps a different equilibrium.A community might encounter shocks, whether through social conflict, or economic or natural disaster, like the Oklahoma tornado, but they find a way to provide basic services and come back to some level of functioning and stability. Flexibility and redundancy of urban systems are characteristics of resilient cities.We find that social isolation is a real risk factor in many disasters and social networks are particularly important [in building resilience]. I’m doing research in the Rockaways [in Queens, N.Y., post-Sandy] and you can see where these informal social networks were important, where people had to rely on their neighbors for the first weeks to feed themselves, to meet basic needs.GAZETTE: Can resilience be planned or designed for?ROSENTHAL: A lot of designers will say yes, because we know how not to plan for it. If you said, “How can we alienate people or make it more difficult to visit your neighbors?” you might invent an automobile-based, low-density city. You’d make it difficult to cross the street and walk through your neighborhood, especially for senior citizens who might not be able to drive anymore.If you design small-scale street grids, clusters and mixed uses, urban greens and pedestrian ways, you’ll get more social connections between neighbors. We need to collect more empirical data, but I don’t think there’s any doubt that making it hard to walk makes it difficult to visit your neighbors. Design isn’t the only factor in social connectedness, but it is one worth investigation and experimentation.There is also a substantial role for urban planners in integrating hazard mitigation, or resilient design, into plans and designs for urban redevelopment. We need to work with communities before disasters to prevent as many hazards as possible and to ensure a healthy recovery.last_img read more

Shumlin announces $575,000 for J & L remediation project in Springfield

Posted On Jan 1 2021 by

first_imgOn Monday Governor Peter Shumlin announced $575,000 in grant funding to begin the environmental remediation process at the former J & L Plant 1 in Springfield.The Governor presented the awards, one for $400,000 from the Southern Windsor County Regional Planning Commission and the other, totaling $175,000 from the Vermont Agency of Commerce and Community Development, to Bob Flint, executive director of the Springfield Regional Development Corporation. SRDC purchased the former J & L property in 2002.The funding will allow work to begin on cleaning up the contamination on the property, specifically the removal of the former chip shed and associated soils behind the building as well as the removal of asbestos from the former office area.The $575,000 was made available to the State and the SWCRPC through ARRA awards from the U.S. Environmental Protection Agency.  Governor Shumlin lauded the strong partnership between SRDC, the Southern Windsor County RPC, the Agency of Commerce and Community Development and the Department of Environmental Conservation.‘This is a great example of how collaboration among local, regional and state entities can be a catalyst for bringing this part of Springfield back to life,’ the Governor said.Flint said, at Monday’s announcement, that the J & L property was a core part of Springfield identity and would now start the path toward becoming part of its future once again.He indicated that the remediation work would begin this summer and this portion would be completed by year-end.last_img read more
