The role of upstream ULF waves in the generation of quasi-periodic ELF-VLF emissions

first_imgRecent work suggests that the quasi-periodic (QP) modulation ~10–50 s of naturally occurring ELF-VLF radio emissions (~0.5–5 kHz) is produced by the compressional action of Pc3 magnetic pulsations on the source of the emissions. Whilst it is generally accepted that these magnetic pulsations have an exogenic source, it is not clear what the mechanism of their generation is. A study of QP emissions observed during 1988 at Halley, Antarctica, in conjunction with IMP-8 satellite solar wind data, shows that the occurrence and modulation frequency of the emissions are strongly dependent upon the direction and strength of the IMF, respectively. The observed relationships are very similar to those previously reported for Pc3 pulsations associated with upstream ion-cyclotron resonance, involving proton beams reflected at the bowshock. In comparing the observed QP modulation frequencies with upstream wave theory, agreement was found by considering wave excitation exclusively associated with a proton beam reflected from a position on the bowshock at which the shock normal is parallel to the ambient IMF direction. Other geometries were found to be either impropitious or uncertain. The work indicates the useful diagnostic role QP emissions could play in the study of compressional ULF waves in the upstream solar wind and in monitoring the IMF conditions responsible for their generation.last_img read more

Lance C. Lantier, Rentz’ commanding officer.Rentz’ interdictions were:Aug. 10, 2013, A U.S. Navy aircraft spotted a suspicious fishing vessel approximately 260 miles north of the Galapagos Islands. Rentz intercepted the vessel and a U.S. Coast Guard LEDET 104 boarding team and Rentz crew members boarded the vessel and discovered some 963 kilograms of cocaine in the fish hold. The contraband was seized and four suspected smugglers were taken into custody.Nov. 30, 2013, the Coast Guard Cutter Rush and LEDET 401 aboard the USS Rentz teamed up to seize some 460 kilograms and detain three suspected smugglers from a Costa Rican fishing boat approximately 50 miles South of Isla de Cohiba, Panama. The vessel had been spotted by a Navy aircraft. Cocaine was discovered hidden in fishing buoys on the boat.Dec. 17, 2013, U.S. Coast Guard LEDET 401 aboard USS Rentz seized approximately 313 kilograms and detained three suspected smugglers from a fleeing Ecuadoran vessel some 240 miles northeast of the Galapagos Islands. The suspected smuggler’s boat was stopped by airborne marksman shooting out their engines.Jan. 20, 2014, U.S. Coast Guard C-130 aircraft spotted a suspicious vessel and coordinated with USS Rentz to intercept it. Coast Guard LEDET 406 aboard the USS RENTZ seized 243 kilograms and detained three suspects who stopped their boat after a Coast Guard marksman aboard one of the USS Rentz’ helicopter fired warning shots.“The reach and impact of our law enforcement teams is greatly expanded by our partnerships with the U.S. Navy, other agencies and nations in the region,” said Rear Adm. Karl Schultz, commander of the 11th Coast Guard District. “The cartels, or transnational criminal organizations behind this smuggling, are engaged in wide-ranging illegal activities, destabilize the regions in which they operate, and engage in brutal and ruthless violence to further their criminal activities. They threaten the security of our homeland and we need to aggressively thwart their smuggling operations. Every shipment stopped denies these criminal organizations the funds and resources they need to perpetuate their violent, destructive practices,” he said.Overall coordination of counter narcotics patrols and surveillance in the Eastern Pacific region is done by an interagency joint task force based in Florida. U.S. law enforcement and the interdiction phase of operations occur under the tactical control and authority of the 11th Coast Guard District headquartered in Alameda, Calif.During their deployment Rentz also transited through the Panama Canal for a port visit to Cartagena, Colombia and to participate in the multinational exercise UNITAS 54-13 from Sept. 7-15, 2013. UNITAS, Latin for “unity,” is a combined South American and U.S. sponsored annual exercise series that incorporates several North and South American nations and fosters friendly, mutual cooperation and understanding between participating navies.Rentz will conduct operations and training within 3rd Fleet’s 50-million square mile AOR upon return.

first_imgQuod is one of those places that just oozes sophistication. I remember coming up to Oxford a year a go and thinking that, thanks to the uplighters on the outside of the building, the soft lighting inside and the (largely) well turned out clientele, that the restaurant must be ridiculously overpriced: suitable only for overpaid North Oxford types or financially overendowed Brookes students. How wrong I was. Quod is, in fact, perfectly affordable. True, you couldn’t ‘do lunch’ there everyday, but there’s no reason why you can’t treat yourself (or get your parents or partner to do the same) every once in a while. It’s Fifth Week, after all. So wash away those blues with a good bottle of moderately priced wine and a steak which will make the idea of writing your fifth (or tenth) essay of the term sail away into a medium rare haze of hedonism.On the whole, the food is very good and the menu is nicely varied. The average main course will only set you back ten to fifteen pounds, and the portions are large enough to warrant the fact that you don’t usually get a side portion of vegetables. Among the best things on the menu are the steak (arguably the best in Oxford), the sea bass, the fishcakes and their confit du canard. All top quality ingredients, all very tasty and filling. Nevertheless, if you do have space for pudding – sample their cheesecake. It’s probably the best I’ve ever had.Moreover, even if their current attire makes them look like pirates, the waiting staff achieve that balance between being too attentive, and ignoring you completely.  But if there’s anything wrong about Quod, it’s that their coffee isn’t strong enough, particuarly if you’ve just had a bottle of wine and full plate of food.  But this is a minor detail. All in all, Quod deserves its reputation as one of the nicer restaurants in Oxford. So, go on: push the boat out this week and indulge yourself. And definitely choose the cheesecake.By Daniel Rollelast_img read more

Eric Mazur wins Minerva Prize

first_imgThe Minerva Academy on Tuesday named Eric Mazur the first winner of the Minerva Prize for Advancements in Higher Education. In announcing the $500,000 award, the academy specifically noted Mazur’s development of “peer instruction,” an innovative teaching method that incorporates interactive pedagogy into the classroom and has been recognized worldwide for driving dramatic improvements in learning outcomes.Mazur is the Balkanski Professor of Physics and Applied Physics and Area Dean for Applied Physics at the Harvard School of Engineering and Applied Sciences (SEAS). The Minerva Prize recognizes one faculty member from any institution worldwide who has made a significant impact on student learning experiences through extraordinary innovation in higher education.“Members of the academy unanimously and enthusiastically agreed on the selection of Dr. Mazur as the first recipient of the Minerva Prize,” said Roger Kornberg, a Nobel laureate and the governor of the Minerva Academy. “His development of the peer-instruction teaching methodology, now broadly adopted, embodies the innovation in teaching excellence that the Minerva Prize was conceived to recognize and promote. We are pleased to bestow this honor upon an individual who has contributed so greatly to the advancement of teaching and with such passion for improving student learning outcomes.”The academy considered a large number of nominations. The three primary criteria in selecting the winner were the innovation itself; its impact on students, faculty, and institutions around the world; and how the innovation has inspired both faculty and students to achieve better learning experiences more generally.More than 20 years ago, Mazur developed peer instruction as an alternative to the lecture-driven class. In peer instruction, the instructor “flips” the classroom, engaging students in interactive discussions about the subject material. Students prepare for class by either reading or watching videos covering the content. Classroom time is devoted to deepening the understanding of the material from the pre-class assignment. Presentations by the professor are interspersed with conceptual questions designed to expose common difficulties in understanding the material. Students are given a few minutes to think about the question and formulate their answers; they then discuss their answers in groups of three to four, attempting to reach consensus on a viable answer.Two decades of research support the effectiveness of peer instruction across disciplines.The methodology has been covered in nearly 1,500 papers in peer-reviewed journals and in numerous books. Mazur’s “Peer Instruction: A User’s Manual” (1997) has been translated into four languages.“Eric Mazur’s innovative thinking has been disruptive in the best sense of the word,” said Dean Cherry A. Murray of SEAS. “He has used a scientist’s mindset to formulate and perfect a new approach to teaching that complements what we already know about how students learn. That’s catching on internationally because it prepares graduates to engage with difficult problems beyond the classroom walls.”Mazur will receive the prize at an academy gathering in October.For more, click here.last_img read more

Alumni Awards

first_imgThe CAES Alumni Association presented the 2019 awards at the 65th  University of Georgia College of Agricultural and Environmental Sciences (CAES) Alumni Association Awards banquet on Oct. 4 at the Classic Center in downtown Athens, Georgia.”The awards banquet was an extremely special celebration as we recognized two men who changed the face of agriculture in Georgia. We acknowledged several alumni who have achieved greatness in their professions and their service to others, and applauded numerous students who received scholarships from the association,” said CAES Alumni Association President Brent Marable. “The night was an accumulation of salutes, all in recognition of many individuals who have contributed mightily to our state’s number one industry and to our college we so dearly love. ” The banquet was headlined by the induction of two new members into the Georgia Agricultural Hall of Fame.Bill Brim, a Tift County farmer and strong advocate for Georgia agriculture, and Foster Rhodes, who was instrumental in establishing the Georgia National Fairgrounds and Agricenter in Perry, Georgia, are the newest inductees into the Hall of Fame. Readers can learn more information about Brim and Rhodes’s accomplishments at year’s Alumni Awards of Excellence were presented to four CAES alumni who have achieved excellence in their chosen fields or their communities. This year’s winners are:Charlie Broussard, BSA 1978, MS 1980, national account manager of Merck Animal Health, launched his storied career in the poultry industry after receiving his bachelor’s and master’s degrees in poultry science from CAES and his Master of Avian Medicine and Doctor of Veterinary Medicine from the UGA College of Veterinary Medicine.
