Magnetospheric line Radiation (MLR) events are relatively narrowband VLF signals that sometimes drift in frequency, and have been observed in both ground based and satellite data sets. Line radiation has been attributed by some authors to be power line harmonic radiation (PLHR), generated from harmonics of the power transmission frequency (50 or 60 Hz) and radiated into the ionosphere and magnetosphere by long power lines. We present the result of a survey undertaken on the basis of measurements made of MLR events observed at Halley station, Antarctica (75°30′S, 26°54′W, L ≈ 4.3) in part of June 1995. Particular attention is given to the frequency spacing, drift rates, and amplitude of the MLR lines. MLR is present in 7.0% of the minute-long VLF recordings made at Halley. The MLR lines rise in frequency as often as they fall. However, these lines do not necessarily rise or fall monotonically and can oscillate while drifting. The Halley MLR has a wide range of line spacings and does not preferentially show spacings near harmonics of electrical transmission frequencies, either 50 Hz or 60 Hz. There is no correlation between the frequency drifts of the local 50 Hz Halley electrical supply and those of the observed MLR lines. The distribution of MLR line spacings observed in the Halley data has a roughly exponential form, suggesting a different mechanism for MLR than for PLHR.

Kennedy Airport to London, with a stop on his way to Yemen, but British authorities returned him to the United States.He continued plotting along with his co-conspirator, 19-year-old Justin Kaliebe, who was later arrested at JFK airport while trying to fly to Yemen to join al-Qaeda. Kaliebe has pleaded guilty to similar crimes and was sentenced to 30 years in prison.Upon learning that he was under investigation, Zea tried to destroy electronic evidence on his computer, but forensic experts recovered it anyway. The materials included violent Islamic extremist materials, such as issues of Inspire, al-Qaeda’s English-language magazine.The two men are the third and fourth Long Islanders to be arrested for trying to join the global terrorist group since its Sept. 11, 2001 attacks. The other two include Samir Khan, a 25-year-old Westbury native, who had been editor of that magazine when he was killed in a U.S. drone missile strike in Yemen in 2011. The first local resident known to join al-Qaeda was Bryant Neal Vinas, a Patchogue native who pleaded guilty to helping the group plot to blow up the Long Island Rail Road in 2008.

Antonio Conte wants to see ‘enthusiasm and desire’ against SPAL on Thursday, to help Inter secure ‘three important points’ in a congested top-four battle. Inter bounced back with a 3-1 win against Torino last time and sit two points behind second-placed Atalanta with one game in hand. With Lazio and Inter on 68 points so far, Conte stressed that his players must continue to give everything to win in Ferrara tomorrow. “Absolutely. We must arrive with the same enthusiasm and desire that we have been showing, doing our best, and try to get the three points that would be very important.” Inter sit eight points behind Juventus but have picked up the most points after 32 games since 2008-09, have 18 different goalscorers, and match the Old Lady on only four defeats all season. “These are numbers that testify the excellent things this team are doing. They must stimulate us to continue like this and do even better going forward.” But Conte is wary of the possible pitfalls ahead of the match against SPAL, who sit rock-bottom in Serie A. “The pitfalls are those of facing the match without the right determination and focus from the off. We face a team that has a poor position in the table, but let’s not forget that they will have great motivation because they play Inter. “We must pay close attention and our attitude will count a lot.” Promoted Content6 Incredibly Strange Facts About Hurricanes7 Universities Where Getting An Education Costs A Hefty PennyBest & Worst Celebrity Endorsed Games Ever MadeLil Nas X Is About To Beat A World Record!7 Non-Obvious Things That Damage Your Phone9 Facts You Should Know Before Getting A TattooEveryone Was Stunned To See How Little Anakin Looks Today10 Risky Jobs Some Women DoWho Is The Most Powerful Woman On Earth?7 Worst Things To Do To Your Phone2020 Tattoo Trends: Here’s What You’ll See This YearA Soviet Shot Put Thrower’s Record Hasn’t Been Beaten To This Day Loading… The Nerazzurri are playing their ninth match in just over a month and Conte has thanked his staff for helping him with the preparation. “It’s a big task, for which I have to thank all my staff who prepare the videos on the opponents and beyond. “We need great collaboration and a quality staff, which, luckily, is what I have.” Conte confirmed that Victor Moses will be back against the Biancazzurri tomorrow and revealed that Nicolò Barella could return against Roma. “Moses is available, Barella has started training with the ball and we hope to have him back against Roma,” Conte explained. “[Stefano] Sensi is healing, [Romelu] Lukaku is getting rid of the contracture and we hope to have him back as soon as possible. “[Matias] Vecino still struggles with his knee and I can’t give any information on that.” read also:Conte: ‘Inter on the right track’ SPAL coach Luigi Di Biagio, who was the Italy Under-21 coach during Conte’s spell at the helm of the Azzurri, is under pressure in Ferrara and the Inter tactician thinks he will learn from the difficulties. “We are talking about a very serious and prepared man, who knows what he wants.

Everton face a battle to hang on to Leighton Baines after Manchester United had an opening bid for the England left-back rejected. United boss David Moyes, who does not technically begin work at Old Trafford until Monday, returned to his former club with a bid of about £12million for the defender, but Press Association Sport understands it was dismissed out of hand by Everton, who have stressed the 28-year-old is not for sale. While the Toffees are determined to maintain that stance it is unlikely to deter United, who can offer Baines Champions League football at a time when he is probably at the peak of his career. Press Association Last season the left-back created 116 chances – more than any other player in Europe’s top five leagues – and was named in the PFA Premier League Team of the Year for the second successive season. Baines has been Everton’s most consistent performer over the last couple of years and while they are not prepared to consider a sale the club value the player, who is close to deposing Ashley Cole as first choice in the national team, much higher. Manager Roberto Martinez, who succeeded Moyes at Goodison Park, is due back in the country on Friday after his commitments as an American television pundit for the Confederations Cup are over. He will meet his full squad for the first time when they return for pre-season training on Wednesday. The Spaniard stressed from the moment he was appointed he wanted to keep his squad intact – with midfielder Marouane Fellaini the other player linked with a number of clubs. Chairman Bill Kenwright reiterated that view on Wednesday when he said: “He (Roberto) wants to hold onto it but he also wants to bring in two or three players in the positions were we need them. “He hasn’t met the squad yet. The first step is to get the players back and get to know them and bring in two or three.” Kenwright reportedly claimed, in 2011, Baines was one of the four players he dare not sell – the others being Fellaini, new captain Phil Jagielka and goalkeeper Tim Howard.

Astrobiology, the science in search of a subject, has major hurdles to overcome in its quest to explain everything from hydrogen to high technology. Despite being one of the most active interdisciplinary research projects around the world (see 01/07/2005 entry), a leading researcher this week conceded that several promising leads of the past are now considered unlikely. Because the biochemicals we know (proteins and nucleic acids) are so advanced and improbable under prebiotic conditions, attempts to generate them or build living systems based on them have proved fruitless. Astrobiologists are having to imagine simpler, hypothetical precursor molecules as stepping stones. If square one was the Miller experiment in the 1950s, this puts them behind square one. Dr. Pascale Ehrenfreund leads a team of astrobiologists at Leiden University in the Netherlands. In the third presentation in a “Life Detection” seminar series at the Jet Propulsion Laboratory (see 12/03/2004 and 11/05/2004 entries for first two), Dr. Ehrenfreund, a specialist in complex molecules in space, who described herself as an experimentalist rather than a theorist, first put astrobiology into the larger context cosmology and astrophysics. Prebiotic molecules either had to be formed in situ on the early earth, or had to be delivered via comets, asteroids, or interstellar dust. She listed 137 molecules that have been identified in space (see Astrochemistry.net), including a number of complex carbon compounds such as polycyclic aromatic hydrocarbons (PAH). Also of interest are some 80 varieties of amino acids identified in meteorites (living things only use 22 of them). So far, this is all chemistry, not biochemistry; but if such molecules could arrive on earth by extraterrestrial special delivery, presumably they could contribute to the “prebiotic soup,” she speculated. Most of the talk consisted of typical astrobiology scenarios and the details of carbon chemistry and interstellar clouds. What really got interesting were the results of her team’s own specific laboratory experiments. They put thin films of amino acids (glycine and D-alanine) into a chamber made to simulate a Martian environment, complete with the UV radiation expected at the surface. The goal was to determine, even if such molecules could form in early Martian lakes, whether they could survive long enough to contribute to prebiotic chemistry. The answer was depressing: the amino acids had a half-life of only eight hours under those conditions. They repeated the experiment ten times with the same results. “We have to implement that knowledge into models of regolith mixing,” she said, “to understand what kind of results that would give, and how long amino acids can survive….” She quickly changed the subject to future Mars missions, but other problematical facts came to light during the presentation and the Q&A session following:Mars: Dr. Ehrenfreund agreed that the Martian Meteorite that sparked the modern astrobiology movement did not contain signs of life. It was useful in retrospect for arousing interest in astrobiology, she said, but the consensus of scientists is that the alleged biogenic markers were produced by purely physical processes.Water: The primary source of water in our oceans was probably not comets, she agreed, but outgassing or water-rich planetesimals from 2-3 AU (see 03/02/2002 entry).Chirality: She agreed that polypeptides have to be 100% one-handed to function, and suggested that maybe adsorption on minerals provided the sorting of otherwise mixed-handed molecules; she conceded, however, that minerals are often heterogeneous.Dilution: The concentration of amino acids in meteorites is exceedingly low; they would have been hopelessly diluted if a meteorite landed in the oceans.Fellowship: She admitted that molecules delivered from space would have to collect somehow in small areas where they could “meet” one another. She suggested small basins or rock layers, but failed to explain how a rapidly-moving meteorite could protect its precious cargo, or how the molecules, once delivered, could be protected from the same UV radiation that her experiments showed were rapidly destructive.Real vs. Virtual: She agreed with Benner (see 11/05/2004 entry) that ribose is very unstable in all conditions, and so are phosphates, the essential backbones of nucleic acids. This forced her to suggest that the biomolecules with which we are familiar were not involved in the origin of life, and that astrobiologists must seek simpler, more stable, more abundant, more primitive building blocks to get life started. Even PNA, a popular alternative to RNA, is already fairly “evolved” and therefore unlikely to be the first, she said. What these more primitive, more abundant molecules must have been to produce something that could be considered alive, she did not specify.Takeover: When confronted with Benner’s argument that you cannot invoke so many ad hoc “genetic takeovers” in an origin-of-life scenario, she dismissed it by claiming Benner is a theorist, not an experimentalist. (Yet Benner’s team had tried hundreds of alternatives to ribose, and all the popular alternatives to RNA, and said they don’t work.)During the Q&A, this reporter mentioned that Benner (11/05/2004) had suggested a desert environment was necessary to stabilize ribose, yet Russell (12/03/2004) countered that was the worst environment because of the radiation, which her experiments seemed to confirm. What was her take on these mutually exclusive scenarios? All she could offer were vague suggestions that comets or meteorites might deliver simpler materials to concentrated areas somehow, perhaps in environments alternating hot and cold between impacts. Most of her answer discussed problems #4, 5 and 6, above. The audience was polite and receptive to Dr. Ehrenfreud, who, given the challenge of the subject matter, was knowledgeable and personable. If they were expecting encouraging laboratory evidence, however, to support astrobiology’s contention that life can originate spontaneously on a planet, most of what they got was, “more work needs to be done.” The entire presentation can be viewed in streaming video from JPL Multimedia. As a footnote, Huygens scientists announced this week that the methane found on Titan was not produced by life, in case anyone was hoping. See the story on Space.com.Astrobiology is a totally bogus science built on the assumptions of Darwinism and naturalistic philosophy. Its only bright side is to motivate more experimental work in chemistry, physics, geology and astronomy – which is good, but assumes no other motive would do so. And its track record is abysmal. Of the biomolecules we know, Dr. Ehrenfreund said, “I wouldn’t really fix on this modern biochemistry thing, and on one component [like ribose or RNA]; we have done that for 50 years, and we didn’t succeed to go any step further with that; so I think you have to think a little bit in a new way.” So 50 years after Stanley Miller proudly announced the formation of amino acids in a laboratory flask, we now know all that was irrelevant hype. Today, the wizards of chemistry are into visualization. They ask us to envision hypothetical simpler entities, yet to be discovered, that might self-organize into self-reproducing machines. So what do you think? Is the “useful lie” tactic the only way to get funding for science? (see 05/02/2003 entry). The Miller experiment used it. The Mars Meteorite used it. Both are now defunct. Is astrobiology a welfare program for scientists who ought to be studying the real world, not hypothetical sci-fi landscapes where primitive molecules “get together” and start living? What if Wall Street acted this way? Would you continue patronizing a financial adviser who, after 50 years, admits that you have lost money on every investment he tried, and said that now you need to think of new, unspecified, unknown, untested investments?(Visited 19 times, 1 visits today)FacebookTwitterPinterestSave分享0
Dingaan Thobela established himself as a charismatic, gifted fighter and a favourite of the South African public.Former boxing champion Dingaan Thobela is known as “The Rose of Soweto”.(Image: Cara Viereckl, via IOL)Brand South Africa reporterDingaan Thobela has proved himself as one of South Africa’s most talented boxers, although perhaps not the most hardworking fighter. The charismatic Thobela started his professional career in 1986 as a junior welterweight, but has since moved up to the light heavyweight ranks – representing a rise of almost 16 kilograms.He has even spoken of possibly campaigning as a heavyweight whether he was serious or not remains to be seen.After an amateur career that saw him win 80 times and lose just three bouts, Thobela’s first professional fight pitted him against Quinton Ryan, a bout he won in four rounds. The slick-punching Thobela was held to a draw in his fourth fight, but proceeded to win 25 fights in a row over the next five years, registering 19 wins by knockout along the way.Dingaan Thobela starts his professional career in 1986 as a junior welterweight, but later moved up to the light heavyweight ranks – representing a rise of almost 16 kilograms. (Image: African Ring)Fighting outside South AfricaAs he scored more and more wins, Thobela became increasingly marketable and began to fight outside of South Africa. In 1990, three of his five fights were in the United States and all three ended in victories, two by knockout over Pascual Aranda and Mauricio Aceves who he both disposed of in the fifth round.In 1991, Thobela’s three contests were all won on points, and in 1992 he fought only twice, defeating Tony Foster over eight rounds and stopping Peter Till in nine rounds.At the beginning of February 1993, “The Rose of Soweto” took on Tony Lopez for the WBA lightweight title. Lopez had previously fought twice against South African boxing legend Brian Mitchell. Mitchell, who retired as WBA champion after 13 successful title defences, had fought Lopez in Sacramento on both occasions. The first bout ended in a controversial draw and Mitchell left the matter in no doubt the second time around.Controversial lossThobela discovered how difficult it was to win in Lopez’ backyard when he lost on a controversial points decision. Four months later he faced Lopez at Sun City, and this time he captured the title.Thobela made his first defence in October, but came up against a superior fighter in the unbeaten Orzubek Nazarov, who claimed a convincing 12-round decision. Thobela challenged for the title again in March 1994, but Nazarov had his number and won over 12 rounds in a repeat of his previous victory. Later in the year Thobela faced journeyman Karl Taylor in England and was surprisingly knocked out in the eighth round of their contest.In 1995 Thobela got back on track with five victories, all of them by knockout, and added a further two KO victories by June 1996. However, matters went haywire again for “The Rose” when he faced Geoff McCreesh in November. McCreesh, who came into the fight with a record of 15 wins and three losses, mostly against little-known British opponents, stunned Thobela in the second round, sending the South African to the canvas for a huge upset victory.Beaten by a journeymanIn his next fight, in March 1997, Thobela was beaten by American journeyman Willy Wise, who came into the fight with 21 wins – only six by knockout – three losses and four draws. The South African was favoured to win, but Wise secured a points victory.Questions were being asked about Thobela’s commitment, but he secured a big win later in the year, defeating fellow South African Gary Murray on a fourth-round TKO. In 1998 he fought only once, drawing against Carlos Baldomir over 12 rounds. Thobela looked rusty and out of shape and doubts grew about his boxing career.However, he returned for two fights in 1999. He won in seven rounds against Walter Danett, but was beaten on points by Cornelius Carr for the WBF middleweight title.World title winIn early 2000 he won a points decision over Soon Botes to earn a crack at Glen Catley’s WBC super middleweight title. The Briton was heavily favoured to retain his crown, but Thobela, way behind on all three judges’ scorecards, staged a strong finish, dramatically knocking Catley out with only seconds remaining in the bout. He was once again a world champion.As had happened previously, Thobela was unable to defend his world title, losing to Canada’s Dave Hilton on a controversial points decision in Montreal. Shortly afterwards, Hilton was jailed for rape and Thobela was given another crack at the title against Eric Lucas in November 2001. He struggled to make the weight, however, and Lucas dominated the fight before winning on a TKO in the eighth round.Thobela was a natural: a gifted boxer who, at the the height of his career, established himself as a charismatic, gifted fighter and a favourite of the South African public.Would you like to use this article in your publication or on your website?
