A general criterion for the release of background potential energy through double diffusion

first_imgDouble diffusion occurs when the fluid density depends on two components that diffuse at different rates (e.g. heat and salt in the ocean). Double diffusion can lead to an up-gradient buoyancy flux and drive motion at the expense of potential energy. Here, we follow the work of Lorenz (Tellus, vol. 7 (no. 2), 1955, pp. 157–167) and Winters et al. (J. Fluid Mech., vol. 289, 1995, pp. 115–128) for a single-component fluid and define the background potential energy (BPE) as the energy associated with an adiabatically sorted density field and derive its budget for a double-diffusive fluid. We find that double diffusion can convert BPE into available potential energy (APE), unlike in a single-component fluid, where the transfer of APE to BPE is irreversible. We also derive an evolution equation for the sorted buoyancy in a double-diffusive fluid, extending the work of Winters & D’Asaro (J. Fluid Mech., vol. 317, 1996, pp. 179–193) and Nakamura (J. Atmos. Sci., vol. 53 (no. 11), 1996, pp. 1524–1537). The criterion we develop for a release of BPE can be used to analyse the energetics of mixing and double diffusion in the ocean and other multiple-component fluids, and we illustrate its application using two-dimensional simulations of salt fingering.last_img read more

Larry Friedel, of 7th Street, Heads to N.J. Surfing Hall of Fame

first_imgBy Donald WittkowskiTwo knee replacements in the past three years and a ripped left hamstring aren’t going to prevent the 65-year-old Larry Friedel from doing what he loves.“I will be back this summer. I will be surfing as soon as the water warms up a touch,” he vowed.Should anyone doubt him, they need only look at his involvement in the surfing community in the past 50 years or so – first as a young competitive surfer and then as a surfing mentor, coach and the owner of Ocean City’s iconic 7th Street Surf Shop.Friedel’s lengthy contributions to the sport will be recognized when he is inducted into the New Jersey Surfing Hall of Fame on Friday night in ceremonies at the Flanders Hotel in Ocean City.Since 1986, Friedel has been a surf shop owner in Ocean City.The New Jersey Surfing Hall of Fame stated that the 12 inductees in this year’s class, including Friedel, have met the “highest level of distinction.”Friedel, who served as a judge for last year’s Hall of Fame class, said he was “kind of surprised” to learn that he was selected as an inductee this year.Although Friedel is being honored, he likes to point out that Ocean City also deserves a lot of credit in the surfing world.“Ocean City is, and always was, a surfing town,” he said. “My doctor is a surfer, my attorney is a surfer, half of the contractors in town are surfers.”He also called Ocean City one of the surfing hotspots on the entire East Coast. He explained that a combination of storms, wind and low-pressure systems can create ideal waves at the Jersey Shore.“There’s been world-class (surfers) in Ocean City that have gone international,” Friedel said of the global buzz in the surfing community.Friedel, center surfer, collects his trophy at a 1968 competition (Mike Monroe is to his right).Friedel and his wife, Becky, oversee four surfing shops in Ocean City under the 7th Street Surf Shop banner. The name is derived from the first shop Friedel opened on the Boardwalk in 1986, overlooking what was then Ocean City’s first designated surfing beach at 7th Street.Long before he became a businessman, Friedel got his first taste of surfing in the 1960s. He transitioned from boogie board-style rafts that he rode as a child to real surfboards when he was still a boy.There were no formal surfing lessons available in those days, so he learned the sport mainly by imitating more experienced surfers.“I grew up surfing,” he said. “You watched people and gave it a shot by emulating them.”Surfing is far more technical these days. As part of Friedel’s mentoring program, the 7th Street Surf Shop offers surfing lessons and also has surfing teams to cultivate young talent.Some of the team members he has coached have advanced to the professional ranks, while others have done well in the amateur East Coast championships.Friedel never surfed professionally, but did have a stellar amateur career, advancing to the East Coast championships in his teens and 20s. In his heyday, he was ranked in the top three among surfers in the New Jersey-New York district and the top 20 in the East Coast standings, he said.He made a comeback in his 30s, when he placed second in the men’s 35-and-over competition in the National Scholastic Surfing Association championships in California in the late 1980s.Friedel holds his surfboard outside the window while riding in an old VW Beetle.Part of the allure of surfing, he explained, are the bonds and camaraderie shared with “like-minded people,” including their affinity for the ocean.Friedel, whose primary residence is Jupiter, Fla., said he still stays in touch with surfers he competed against when he was a teenager. One brand of surfboards he sells at the 7th Street Surf Shop is made by Bill Stewart, an old high school buddy of his from Florida.Friedel attended South Broward High School in Hollywood, Fla., but spent his summers in Ocean City working at his parents’ Boardwalk business. In 1976, he opened his own arcade business on the Boardwalk.When 7th Street became Ocean City’s first official surfing beach, Friedel envisioned opening a Boardwalk surf shop in the heart of the town’s surfing hub. So, in 1986, the 7th Street Surf Shop was born. Over the years, he expanded to three other surf shops in Ocean City.The Boardwalk location suffered a devastating fire in May 2015 caused by an electrical malfunction. A little more than a year later, the shop was reopened after the building was restored. Friedel noted that it was a huge challenge getting the shop back in business.In between the demands of running his shops, Friedel still finds time to surf. Even at 65, he considers himself a competitive surfer.“When you love something that simple, it has a tendency to reach into your soul,” he said.In a recent photo, Friedel shows he’s still got it. In a 1967 competition, Larry Friedel shows off the form that made him a top amateur surfer. (Photos courtesy Larry Friedel)last_img read more

Statement to parliament: Second additional provision to the High Speed Rail (West Midlands – Crewe) Bill

first_img an insertion to allow easements over land to be for the benefit of a third party (ie utility companies) rather than for the benefit of the Secretary of State dis-application of some sections of the Building Act 1984 in relation to demolitions which are already otherwise authorised by the bill increasing the controls on the nominated undertaker in relation to low-volume lorry movements the lowering of the viaduct at Kings Bromley which reduces environmental effects such as visual impact a revised and more simple Handsacre junction layout, where Phase One connects to the West Coast Main Line a new traction power connection, requiring over 7 km of high voltage electricity lines, from the HS2 line at Newlands Lane to the east of the route – this change ensures the necessary resilience and redundancy required for traction power on a high speed railway temporary and permanent power supply routes to the Whitmore and Madeley tunnels, to support the operation of the tunnel boring machines during construction and later, the operation of the tunnels a southward extension of the southern end of the tunnel at Whitmore, to avoid the need for complex surface works where the A53 crosses the route works at and around Crewe station including the extension of platform 5 to accommodate 400m HS2 trains – these changes support the realisation of the Crewe Hub vision I would like to inform the House about the introduction of a second additional provision to the High Speed Rail (West Midlands – Crewe) Bill, which is currently before a Select Committee.As part of this government’s industrial strategy we are investing in High Speed 2, a transformational infrastructure project that will improve people’s journeys, create jobs, generate economic growth and help to rebalance our country’s economy. HS2 is more than a railway and the project’s vision is to be a catalyst for economic growth. It has cross-party support and support from councils, local enterprise partnerships, metro mayors and businesses who can see the transformational potential.HS2 is making progress and the benefits are already being seen in towns and cities in advance of HS2 services. Around 2,000 businesses have been awarded HS2 contracts and over 7,000 jobs have been supported, a figure that will increase to around 30,000 at peak.The additional provision proposes a number of changes to the powers in the bill for the select committee’s consideration. These changes have arisen as a result of requests from petitioners, directions from the select committee currently considering the bill, and further design development, principally in relation to utility works.Those directly and specially affected by these changes may petition against them, and once any petitioners have been heard, the committee will decide whether the amendments to the bill should be made. The main changes in the additional provision are as follows: The additional provision also includes works and powers related to utilities following detailed discussion with utility companies. Other changes relate to highway safety and capacity improvements.All of these changes require additional land to be acquired, and/or works to be carried out. In some cases land now affected is at some distance from the line of route. Full details are shown in the plans and sections deposited alongside the additional provision. Affected landowners will receive notification this week, including information on how to petition against the changes, should they decide to do so.The following amendments are also included in this additional provision: I am also publishing an environmental statement setting out the significant effects and mitigation from the changes in the additional provision, alongside a supplementary environmental statement reporting new environmental information relating to the scheme. In accordance with standing orders, there is a public consultation on these documents which will run until 29 March 2019. The documents will be put in the Public Bill Office of the House, and will also be made available in locations open to the public in all local authorities and parishes affected by the changes.In October 2018 I committed to updating the House regularly on the progress of HS2. I intend to make further statements to this House to update colleagues on HS2’s progress during the course of 2019.last_img read more

Forum considers religious education

first_imgThe second installment of the Notre Dame Forum “What do Notre Dame graduates need to know?” evaluated the role of theology at Catholic universities Monday, featuring Huisking professor of theology at Notre Dame Cyril O’Regan and chairwoman of Boston College’s theology department Catherine Cornille.Emmet Farnan | The Observer University President Fr. John Jenkins said he hoped the discussion would emphasize the importance of theology for Notre Dame and inform the University’s decisions during the current curriculum review.“In a sense, as we think about curriculum review, we’re thinking about also the minds and character of the students who graduate,” Jenkins said. “We want them to be people informed by the Christian tradition — theology, as well as people who can intelligently engage in the conversation between faith and reason.”O’Regan said Notre Dame emulates the theological education described in Cardinal Deacon John Henry Newman’s reflections.“Newman’s reflection on the Catholic university especially bears on the inspiration to found the University of Notre Dame,” he said. “Newman and Fr. Sorin knew that the idea of a Catholic university could not be an oxymoron.”O’Regan said although many believe that theological and secular education cannot coexist, it is not only possible but necessary to include both in a Catholic university education.“There was a sense that all forces secular put pressure on the whether and how ‘Catholic’ … and ‘university’ appeared to be in conflict,” he said. “It made the logic that of a zero-sum game – the more of one, the less the other and vice versa. The pressure to pull apart [‘Catholic’] and [‘university’] will intensify and will likely continue to intensify. … Newman thought that the pressure not only had to be resisted, but could be.”Cornille said it is also necessary to teach students about other faith traditions.“I think it’s important for our students to learn how to engage other religious traditions in a constructive way, how to open oneself up to learning from other religious traditions and in turn, reflect constructively on what that means for the Christian faith or for one’s understanding of that particular theological topic,” Cornille said.Cornille said ultimately, Catholic university students must learn how to engage and approach theology as a spiritual pursuit, rather than a simply factual one.“I think we have this challenge to teach theology as a spiritual discipline, to expose our students to the spiritual richness and depth of the tradition to the radicalness of theology,” she said. “Most students don’t regard theology as a radical discipline, but once they are exposed to [it] I think that this could really awaken them in new ways to what theology could mean and how it could contribute to their own lives.”Tags: Catholic university, Notre Dame Forum, What do Notre Dame graduates need to know?last_img read more

Retirement planning 101: Your top 401k questions answered

first_imgby: Kristen HicksWe all know we want to retire, but figuring out the right retirement plan to get there can seem pretty complicated. If you have questions about how a 401k works or how to make sure your retirement plan is solid enough, hopefully our 401k FAQs can help. How does a 401k work?A 401k plan is a benefit commonly offered by employers to ensure employees have money to retire with. A set percentage is automatically taken out of each paycheck and invested in a 401k account made up of investments (usually stocks, bonds, mutual funds) that the employee can pick themselves.Depending on the particulars of the plan offered by employers, the money invested may be tax-free and matching contributions may be made by the employer. If either of those benefits are included in your 401k plan, financial experts recommend contributing the maximum amount each year, or as close to it as you can manage.How much can you contribute to a 401k?

CDC funds work on rapid tests for avian flu

first_imgDec 4, 2006 (CIDRAP News) – The Centers for Disease Control and Prevention (CDC) has awarded four contracts worth $11.4 million in an effort to develop a 30-minute test for H5N1 avian influenza.The CDC said it awarded the funds to spur development of tests that doctors and field epidemiologists could use to test patients for both H5N1 and other flu viruses. Currently, testing for H5N1 in the United States must be done in 1 of about 100 designated laboratories and takes from 4 to 24 hours, depending on shipping time, the CDC said.Last month the World Health Organization (WHO) listed a rapid diagnostic test as one of the top priorities in avian and pandemic flu research. The CDC said it hopes a rapid test can be ready and licensed within 2 to 3 years.”The creation of a point-of-care test to rapidly detect human cases of H5N1 avian influenza would be a major step forward in our ability to protect public health,” Health and Human Services Secretary Mike Leavitt said in a news release.The four companies, their tests, and the contract amounts are as follows:Cepheid, Sunnyvale, Calif.—GeneXPert Flu assay, $2.4 millionIquum, Marlborough, Mass.—LIAT, Lab-in-a-Tube, $3.8 millionMesoScale, Gaithersburg, Md.—Multi-Array Detection, $706,241Nanogen, San Diego—a novel point-of-care immunoassay system, $4.5 millionOver the next year, the companies will work to develop tests that can detect flu viruses and distinguish seasonal strains from H5N1 within 30 minutes, the CDC said. Existing rapid tests can tell only if a patient has a seasonal influenza A or B virus.CDC spokeswoman Christine Pearson told CIDRAP News the contracts are intended to fund the first two of five development phases.The goal for the first two phases is to produce a prototype test that can be evaluated by the CDC, said Dr. Ruben Donis, chief of the molecular virology and vaccines branch in the CDC’s influenza division. He said the agency will fund further development only if the prototype has “acceptable performance characteristics.”In a news release, Nanogen said that if the CDC funds all five development phases, the company would receive a total of about $12.5 million over the next 2 to 3 years.The four companies were chosen from 13 applicants, the CDC said. Selection criteria included the technical specifications of the test, experience in developing diagnostic tools, staff expertise, and access to labs with sufficient security to handle H5N1 viruses.The agency also promised to provide funds for a repository of influenza reagents and other materials to help in development of the tests.See also:Dec 4 CDC news releasehttp://www.cdc.gov/media/pressrel/r061204.htmlast_img read more

Lothian may ‘subsume’ transport scheme amid merger considerations

first_imgThe strategy shift would also establish a distinct fixed income asset class, targeting an exposure of 22% by 2021, rather than the estimated 10% of fixed income assets held within alternatives, as at present.The consideration to merge comes after Lothian Pension Fund successfully implemented a second, standalone investment strategy for certain employers sponsoring the fund.The report said the unitisation strategy allowed for a 100% exposure to index-linked Gilts, while its current strategy would be employed for the remainder of the scheme’s employees.It added that there was scope to increase the number of different strategies managed by Lothian.“The unitisation functionality could help with implementation of the new investment strategy for the Lothian Buses Pension Fund, as it allows more flexible allocation of investments,” the report adds.“It would also bring other efficiencies such as accounting, actuarial valuations and investment manager arrangements.”Dunn’s report added that the merger should happen at the “most appropriate timing” but that further consultation with stakeholders – such as Lothian Buses – was needed before it progressed.The changes would have no affect on a third pension fund managed by Edinburgh Council.The local authority is also responsible for the management of the £155m Scottish Homes Pension Fund, sponsored by the devolved Scottish government.English and Welsh local authority funds have been discussing mergers over the last few years as part of the UK government’s desire to increase scale in the LGPS sector, but the Scottish LGPS remains exempt.The plans were eventually dropped in favour of the creation of asset pools, of which between seven and eight are now emerging following talks within the sector. Lothian Pension Fund may soon merge with a smaller scheme for transport workers, in plans being considered by the City of Edinburgh Council.The council is responsible for the management of two local government pension schemes (LGPS) – the £4.4bn (€6bn) Lothian Pension Fund and the £386m Lothian Buses Pension Fund – but it has allowed both to remain standalone funds.In a report prepared for the respective funds’ most recent pensions committee, the council’s acting director of resources Hugh Dunn said the buses fund was established as a sub-fund of the larger LGPS, with a clause within the regulation allowing for it to be “subsumed” into Lothian Pension Fund.Dunn said the option of merging with the larger fund had been “highlighted and explored” as part of an ongoing review of the transport scheme’s investment strategy, which proposed that it gradually reduce its equity allocation in favour of bonds, while lengthening the exposure of its fixed income portfolio.last_img read more
