  • What controls photochemical NO and NO2 production from Antarctic snow? Laboratory investigation assessing the wavelength and temperature dependence

    first_img[1] Laboratory experiments were conducted to determine the wavelength and temperature dependence of NO and NO2 release from Antarctic snow. This photochemically driven process has been observed during recent field measurements in polar regions. In this work the photochemical production of NO and NO2 was reproduced under laboratory conditions with NO2 dominating the production. The wavelength of incident light was varied over the range 295-385 nm. We observed a lambda dependence where NO and NO2 release ceases when the snow was illuminated with lambda > 345 nm. Comparing these data with the aqueous absorption cross section of the nitrate ion (NO3-) indicates that NO3- is the precursor N-oxide species, which is photolyzed in snow. The temperature of the experimental system was varied over the range 253-243 K with no effect on NO and NO2 production. The occurrence of these photochemical processes followed by release to the atmosphere will impact the chemistry of the boundary layer over any snow-covered region. In addition, understanding these processes is essential for accurate ice core interpretation.last_img read more

  • MLB hammers Astros hitting coach Alex Cintron with historic suspension for ‘escalating conflict’

    first_imgCintron, who spent nine MLB seasons as an infielder, hid behind his players when Laureano came at him. Astros catcher Dustin Garneau tackled Laureano, preventing the scene from getting uglier.Laureano charges the Astros dugout and the brawl breaks out pic.twitter.com/CQ2K8kFnlb— A’s on NBCS (@NBCSAthletics) August 9, 2020Laureano said Monday that he should not have attacked Houston’s bench, even if he felt provoked. MLB has been clear about limiting physical interactions during the COVID-19 pandemic.The A’s and Astros won’t face each other again until Aug. 28. Astros hitting coach Alex Cintron received a 20-game suspension Tuesday for his role in a fight with the A’s this past Sunday, meaning he’ll be away from his club for one-third of the abbreviated 2020 season. It’s the longest MLB ban for a game-related incident in 15 years and particularly notable for being assessed to an assistant rather than a player or manager. Cintron goaded A’s outfielder Ramon Laureano into charging the Astros’ dugout after Laureano was hit by a pitch for the second time in Sunday’s game. He motioned with his finger for Laureano to fight him, and Laureano said Cintron made a comment about his mother, which Cintron denies. Laureano was suspended six games for his role in the altercation.MLB wrote in a statement that Cintron’s suspension came for “inciting and escalating the conflict between the two clubs.””I accept MLB’s suspension and will learn from this,” Cintron wrote in a statement. “Although I never referenced Ramon’s mother, my actions were inappropriate. I apologize for my part in Sunday’s unfortunate incident.”As coaches, we are held to a higher standard and should be an example to the players.”MORE: Why Laureano was suspended fewer games than Joe Kellylast_img read more

  • Why Academia Leans to the Left

    first_imgWhy do PhDs in academia tend to be politically liberal?  A paragraph in Science magazine’s feature “Random Samples” on December 21 suggested a reason: conservatives value other goals, like going into business to make money, or choosing to stay home and raise a family.1    “Why are academics in the United States so politically liberal?  Are conservative students oppressed by a biased professoriate, or are liberals simply smarter?  Neither,” was the conclusion of two scientists in Pennsylvania who surveyed 15,000 college students.The Woessners found that self-described liberals and conservatives report no difference in grades or in the quality of their education.  Yet liberal college students are twice as likely as conservative ones to pursue Ph.D.s  The main reasons, the authors conclude, are differences in values, goals, and preferences.  Liberals placed higher values on creativity; conservatives were more oriented toward raising families and making money.The findings apparently held for the hard sciences as well as for social sciences and humanities.    An accompanying graph shows a steep rise on the “far left” side for those seeking doctorates, while moderates and “far right” individuals could care (somewhat) less.  Another visually-apparent result on the graph is that conservatives and moderates, as seniors, tend to feel the same way about their goals as they did as freshman.  Liberals, however, tend to warm up to a doctoral program as they approach their senior year.1.  “Random Samples: Left on Campus,” Science, Volume 318, Number 5858, Issue of 21 December 2007.Surveys and graphs have only limited credibility because of the possibilities of biased sampling and leaving out relevant causes (see Baloney Detector on statistics).  At least Science admitted that liberalism is rampant at the university (see 12/02/2004), and also confessed that liberals (and PhDs) are not necessarily smarter.  (The vulgar translations for the acronyms B.S., M.S. and Ph.D. may be apropos here.)*    It appears that conservatives are the fittest, working hard to pass on their genes, while liberals are like parasites, advancing primarily by taking over the host (the classroom) and churning out clones to infect other cells.  A university setting is a contrived, unnatural environment where the parasites thrive.  In the open air of true academic freedom, where the parasites would have to compete in the real world, the results might be quite different. (Visited 33 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

  • Virgin Australia on the up despite turbulence

    first_imgVirgin Australia has recorded a significantly wider net loss of A$228.4 million for last financial year after taking a hefty charge for cost-cutting and fleet restructuring.The result compared to a 2014-15 statutory loss of $93.8 million and translated to underlying profit before tax of $41 million, which was in the middle of the airline’s $30m to $60m guidance.The airline said this was an improvement of $90.1m on its fiscal 2015 underlying pre-tax performance and an $118.6m rise if calculated on a like-for-like basis taking assuming 100 per cent ownership of Tigerair Australia.It did not specify the magnitude of the charges but has previously indicated they were expected to be between $410 and $450 million. The airline is streamlining its management. Improving procurement and simplifying its fleet as part of moves to repair its balance sheet.It plans to cut between four and six ATR turboprop aircraft, quit its Embraer E190 fleet and progressively move Tigerair Australia from Airbus A320s to Boeing 737s. This in addition to eight Fokker regional aircraft that have already gone.The changes are part of a strategy targeting net free cash flow savings of $300m per year by the end of fiscal 2019 and cumulative cost savings of $1.2 billion by the end of the 2017 financial year.The annual figures were revealed in fourth-quarter results showing an underlying pre-tax loss of $21.9m, a $15m improvement on the same quarter last year.Virgin’s decision to keep a tight rein on capacity saw the group load factor rise 4.5 percentage points for the quarter to 79.7 per cent as group passenger numbers rose 4.2 per cent. Virgin’s domestic load factor rose by 5.8 per cent as passenger numbers increased 4.6 per cent compared to the previous fourth quarter, while low-cost offshoot Tigerair Australia saw a 3.3 point load factor increase off a 15.4 per cent jump in passengers. “The Group improved its underlying performance, passenger numbers and load factors in the fourth quarter in a challenging operating environment’’ chief executive John Borghetti said. “During the quarter, the group took action in response to operating conditions through strategic capacity reductions in line with demand.’’Macquarie Equities analyst Sam Dobson said the increase in domestic load factors and a two per cent reduction in capacity reflected a rational response to demand weakness.Virgin Australia will report its 2015-16 annual results in full on August 5.last_img read more

  • Germany joins SKA Organisation

    first_img7 January 2013Germany has become the 10th member of the organisation that will participate in the detailed design of the Square Kilometre Array (SKA) telescope, joining existing members Australia, Canada, China, Italy, the Netherlands, New Zealand, South Africa, Sweden and the United Kingdom. India is an associate member.Construction on what will be the world’s largest and most sensitive radio telescope is due to begin in South Africa and Australia in 2016.Professor John Womersley, chair of the board of the SKA Organisation, welcomed the membership of the Federal Ministry of Education and Research (BMBF), representing Germany.‘Excellent track record in science megaprojects’“Germany has an excellent track record not only in radio astronomy but also in the management and delivery of science megaprojects and associated engineering. This expertise will be of great benefit to the SKA project as we move towards the construction phase of this inspirational telescope”, Womersley said in a statement last monthDr Beatrix Vierkorn-Rudolph, Deputy Director General, Federal Ministry of Education and Research and Professor Michael Kramer, Director of Max-Planck-Institut fur Radioastronomie, an institute of the Max-Planck-Gesellschaft (MPG), have been appointed to represent Germany on the SKA Board of Directors.Germany will contribute €1-million to the SKA Organisation, financed 50% each by the BMBF and the Max-Planck-Gesellschaft (MPG).Professor Michael Kramer, director of the Max-Planck-Institut fur Radioastronomie, an institute of the MPG, said the unprecedented scale of the multi-national SKA project “ensures that we will continue to be able to push the boundaries of physics and astronomy.“The SKA genuinely has the potential to completely transform our understanding of the universe as we know it today”, Kramer said in the statement.Dual site to maximise on investmentsIn May 2012, the members of the SKA Organisation agreed on a dual site for the SKA to maximise on investments already made at the candidate sites in Australia and South Africa.“Both sites offer exceptionally radio quiet environments for detecting very faint radio waves from the early universe, and many thousands of SKA receptors will soon be constructed across these two desert regions,” the UK-based organisation said.As a member of the SKA Organisation, Germany has voting rights and is eligible to appoint two representatives to the board of directors, which has the authority to appoint senior staff, decide budgets, admit new project partners to the organisation, and direct the work of the global work package consortia in the SKA pre-construction phase.The Square Kilometre Array will have a total collecting area of approximately one square kilometre, giving it 50 times the sensitivity and 10 000 times the survey speed of the best current-day telescopes. It will have thousands of receptors extending to distances of 3 000 kilometres from its core regions.The telescope is expected to address fundamental unanswered questions about our Universe, including how the first stars and galaxies formed after the Big Bang, how dark energy is accelerating the expansion of the Universe, the role of magnetism in the cosmos, the nature of gravity, and the search for life beyond Earth.SAinfo reporterlast_img read more

  • Taking a look at the role of USDA reports in the market

    first_imgShare Facebook Twitter Google + LinkedIn Pinterest The USDA report last week held few surprises. Corn carryout was slightly lower and beans were slightly higher than expected. There are still feed usage questions with all of the excess milo and wheat in the market, but that might not be resolved until sometime in the future.The corn crop continues to look amazing throughout most of the Corn Belt. Beans are also looking good, but have slipped slightly. Hot and dry forecasts dominate one day and then rain forecasts are shown the next day. Expect concern over corn kernel fill to continue while bean potential to be wide open. Weather’s effects on the corn market may be nearly over after this week.Corn harvest started in southern Texas, and so far the yields are the best ever for this region. As harvest moves north expect the basis to drift lower as corn is more available. Also with the impressive wheat harvest, storage space may be at a premium this year.While some are calling for above trend-line yields, I expect the national corn yield to be trend-line at this point. Even if a heat wave drops yields by five bushels, overall production would still leave balance sheets with more than ample supply. Above trend-line yields would likely suppress prices further. Market actionPotentially the market could trade sideways through the end of the year. So, on 5% of my planned 2016 production, I sold Dec futures at $3.72 and then sold a $3.50 Dec CALL and a $3.50 Dec PUT for 48 cents. This trade expires near Thanksgiving. What Does That Mean?• If corn is below $3.50 near Thanksgiving I sell nothing but collect 68 cents premium (Futures gain of $3.50 to $3.72 = $.22 + $.48 in option premium). This can be added to a later trade.• If corn is between $3.50 and $3.72 I’ve sold corn for $3.98 to $4.20. I collect 48 cents at $3.50 and lose 1 cent for every penny the market is off that number. For instance, I lose 22 cents premium if it is $3.72.• If corn is above $3.72 I’ve sold 5% of my production for $3.72 and I have to sell another 5% of production for $3.98. If this happens I would move this additional sale to 2017 for a 20-cent premium (which is what is available in the market today) and have a sale near $4.20.I don’t really like selling $3.72 futures, but if prices go lower I’m protected with this trade to an extent. However, if prices rally, this trade doesn’t hurt me either. I think the chance of a sideways market is really high at this point. If I’m right, this could be one of my best trades of the year. Market equilibriumUSDA reports can send significant ripples through the market after they are published. Following provides a simplistic overview of how prices are determined, USDA’s role and why it seems impossible to predict future prices with any kind of accuracy. What is job of the market?The job of the market is to “guess” final production and demand levels. The market consists of “futures” for a reason. It’s forward looking and constantly addressing new information to help it place prices at the right point. How does the USDA factor in?The USDA is an independent report that estimates grain production as accurately as possible in the U.S. and around the world. While conspiracy theorists think the USDA puts out numbers to control prices, that shouldn’t be the goal. It is in our nation’s best interest to not have any surprise shortages of food around the world, because this could lead to unstable regimes and security issues for the U.S. Providing accurate and timely reporting on crop production stabilizes prices. If prices were artificially too low, then too much grain would be sold (causing shortages). If prices are too high, it would create a situation similar to what China is currently facing, grain goes unused and begins to deteriorate. How accurate is the USDA?Every year we hear analysts say that the USDA balance sheet is tight and has “no room for margin of error.” This is pretty much the story every year. It’s the job of the market to predict the final outcome of production before it’s ever really known. Realistically, the corn balance sheet has the potential for a 10-bushel per acre swing, which is usually narrowed leading up to harvest. Thus for each bushel the USDA is off, it could cause a price swing of 20 cents.Soybeans only need a two-bushel per acre swing to cause massive volatility in the markets. So a two-bushel drop in trend-line bean yields could push prices $2 per bushel higher (and same with a two bushel increase — a  $2 decrease). This means each tenth of a bushel represents 20 cents to the market price. What happens when the USDA is off on their estimates?If the USDA is off even a bushel on its bean estimate, it’s a 2% miss. For corn a 2% mistake means missing the estimate by 3.32 bushels per acre. This narrower margin for beans is why prices are more volatile around reports. What other information in the USDA report affects prices?Many other demand components affect prices beyond yield estimates:Export counts for last year and estimates for next yearOther country’s weather conditions and crop production can affect supply and demand from that countryFeed demand, which is hard to predict because weather can change demand throughout the year needed for livestock. Maybe we shouldn’t follow the USDA reports so closelyMaybe, but what is the next best substitute? Information from private firms could easily be manipulated for their personal financial gain. Plus, how would private numbers be much better than the USDA? While there may be frustration around the USDA, most traders still use the USDA numbers for estimates as well as private firms.The bottom line is that market prices are based upon “guessing” what will be produced and what will be used. It’s supply and demand. It’s not complicated in theory, but at the same time, very complicated in reality. Weather has a huge impact, and it is still impossible to predict more than two weeks out (if that). So, until weather can be predicted more long-term, it will be virtually impossible to predict prices any better than we currently do.This is why it’s so important to have a plan in place. As a grain producer you need to sell big rallies and certainly when prices move into profitable levels. A $1 per bushel drop in less than a month, for the second year in a row should make every farmer realize that next time around. However each time the market rallies nobody ever thinks it will go back down.Jon grew up raising corn and soybeans on a farm near Beatrice, NE. Upon graduation from The University of Nebraska in Lincoln, he became a grain merchandiser and has been trading corn, soybeans and other grains for the last 18 years, building relationships with end-users in the process. After successfully marketing his father’s grain and getting his MBA, 10 years ago he started helping farmer clients market their grain based upon his principals of farmer education, reducing risk, understanding storage potential and using basis strategy to maximize individual farm operation profits. A big believer in farmer education of futures trading, Jon writes a weekly commentary to farmers interested in learning more and growing their farm operations.Trading of futures, options, swaps and other derivatives is risky and is not suitable for all persons.
