Simulated ADCP vertical velocity fields from the foray-type scenario resembled field observations, particularly with regard to the occurrence of positive anomalies in deeper waters and negative anomalies in shallower waters. The model illustrates that active vertical flux of zooplankton FP can occur at high latitudes even when no synchronised VM is taking place.last_img read more

Scott Minium relieved Capt. John Russ as commander of the squadron.Rear Adm. James F. Caldwell, Jr., Commander, Submarine Force U.S. Pacific Fleet, was the guest speaker and spoke on Russ’ diligence, tenacity and sense of ownership as commander of the submarine squadron.“The success of the team depends on the leadership at the helm and the commitment of the team,” Caldwell said. “To the crews of our Guam submarines: Your mission cycle is demanding. It is unlike any other submarine homeport in our nation. I think of it as a proving ground for the best and most operationally focused submarines in our force.”Following his remarks, Caldwell presented Russ with the Legion of Merit for impressive leadership of the Navy’s only forward-deployed submarine squadron. Russ oversaw 36 voyage repair periods for visiting submarines and managed four forward-deployed submarines that supported 13 U.S. 7th Fleet operations. Russ also oversaw three inter-fleet transfers and laid the groundwork for three more.During his remarks, Russ expressed great satisfaction with CSS 15’s mission priorities of “war fighting first, operate forward and readiness.”“I’ve been blessed with the best submarine skippers and crews in the fleet; they are motivated, talented and ingenious submarine warriors,” Russ said. “As our Navy’s only forward-deployed submarine squadron, operating at the tip of the spear in Guam is exactly what this amazing staff and our forward-deployed submarines and tenders do best.”As Minium assumed command of CSS-15, he praised Russ for the squadron’s efforts in improving submarine operations in Guam.“There is the towering legacy of the past, a strong pattern of success and improvement that started with the standing up of Squadron 15 in 2001,” Minium said. “Since then, each successive commodore and his staff have worked to improve submarine operations in Guam, and the benefits of their efforts have often reached far beyond the submarine force. Taking command of a successful organization is both humbling and daunting, and I’m sure I speak for every member of the squadron when I say the best we can do to honor your work is to add our own chapter to this fine legacy.”Russ’ next assignment is chief of staff of Commander, Submarine Group 7.CSS-15 provides maintenance, training, logistics and administration support for the submarines assigned to U.S. 7th Fleet.[mappress]Naval Today Staff , March 14, 2012; View post tag: Ceremony View post tag: change View post tag: City View post tag: boardcenter_img View post tag: Command Back to overview,Home naval-today Submarine Squadron 15 Holds Change of Command Ceremony on Board USS Oklahoma City View post tag: Navy View post tag: holds Submarine Squadron 15 Holds Change of Command Ceremony on Board USS Oklahoma City Authorities View post tag: submarine View post tag: Naval Share this articlelast_img read more

Uni Parks in murder search

first_imgOxford was the scene of a large-scale police operation over the Bank Holiday weekend as around 100 officers searched for a man suspected of killing three people in Didcot. The body of Jed Allen, 21, was discovered by two members of the public in a wooded area next to a cycle path off Marston Ferry Road shortly before 5pm on Monday 25th May. Allen had been sought by the police following the discovery of the bodies of his mother, Janet Jordan, her six-year-old daughter Derrin, and her partner Philip Howard, 44, at an address in Vicarage Road, Didcot, on Saturday evening. All three had suffered fatal stab wounds. Police later recovered a knife, believed to be the murder weapon, from the scene. Officers are not looking for anyone else in connection with the murders, and an inquest will be opened in due course. The head of thames Valley Police’s Major Crime Unit, Det Supt. Chris Ward, said in a statement, “My condolences go out to the families and loved-ones of Janet Jordon, Philip Howard and Derrin Jordon. We have specially trained officers with the families and we will continue to support them at this extremely difficult time. “I would like to thank the public for all their help during this investigation, as well as their patience while we have been carrying out searches across Oxfordshire. I would especially like to thank the residents of Didcot who have cooperated with the police during this tragic period.” University Parks were closed to the public on Sunday as part of the police search. A police helicopter was seen hovering over the area, whilst officers undertook searches inside the 70-acre site. Some of the police officers were wearing riot gear or being assisted by sniffer dogs. Armed officers were also sighted at the parks. The site reopened to the public on Monday morning.  “Looking back, it’s pretty eerie to think how close it all was. These awful things don’t normally happen so close to home.” Another Merton student and Oxford native, Charles Graham, told Cherwell, “I was walking my dogs on Wolfson College land, and walked into the line of eight or so police officers, all with guns, and some others with police dogs. “They said I could continue on my walk as long as my dogs were on their leads, and said I had to go behind the police line – so I was allowed to walk my dogs back towards University Parks. “A helicopter stayed above us all the way during our walk, until we returned to our car.” Allen is believed to have moved from Didcot to Oxford on Saturday evening. Police had not previously searched the area off Marston Ferry Road where Allen’s body was found. Police were also seen searching the grounds of Lady Margaret Hall on Sunday. A second-year LMH student told Cherwell, “It all suddenly felt a bit more real when I saw two armed police and a porter walk past my window. I didn’t feel nearly as safe after that.” On the day when Allen’s body was discovered, Merton students were playing cricket in the Merton Recreation Grounds close to where the body was found. Charlie Atkins, a second-year Mertonian, commented, “We were playing cricket in a field just across from the where they supposedly found Allen. The helicopter was very close by, but I didn’t really sense what was happening at the time.last_img read more

Forward, into the past

first_imgIf you’re an undergraduate or graduate student and have an essay to share about life at Harvard, please email your ideas to Jim Concannon, the Gazette’s news editor, at [email protected] This summer I worked on an intriguing research project on active galactic nuclei (AGN) at the Harvard Smithsonian Center for Astrophysics (CfA). AGNs, which include quasars, are some of the most interesting and spectacular phenomena in astrophysics and rank among the most luminous, distant, and oldest objects in the universe. AGNs can be distinguished from normal galaxies by the fact that they typically radiate energy from a compact central source, a black hole, which is equal to or brighter than all of the stars in its galaxy.I have been interested in astronomy and physics since I was 5 years old, and in particle physics, cosmology, and astrophysics in more recent years. So when I was offered the opportunity to conduct research at the CfA this summer with support from a Herchel Smith Harvard Summer Undergraduate Research Fellowship, I was thrilled.The CfA is a remarkable place where, in addition to being home to the Harvard Astronomy Department, more than 500 astrophysicists conduct some of the most advanced astrophysics research in the world.  My research advisers at the CfA were Martin Elvis, a senior astrophysicist and a leading authority on quasars and AGNs, and Francesca Civano, a postdoctorate fellow and rising figure in the field.The CfA also operates ground-based telescopes in Arizona and Chile and is heavily involved with space-based telescopes like the Chandra X-ray Observatory, launched from the Space Shuttle in 1999. Earth- and space-based telescopes are important to astrophysicists because they allow them to look out great distances (and therefore far back in time) to study complex questions, including how the universe developed and evolved.In my own research, data from the COSMOS Survey, obtained by the powerful Keck telescope in Hawaii, allowed me to look back billions of years in time at the light and physical properties of AGNs as they existed when the journey of their light began. So, in a very real sense, telescopes can be thought of as virtual time machines, since we view light that was emitted long ago.There are a number of reasons why active galaxies can be considered among the most spectacular of all astronomical objects. Perhaps the most prominent is that the source of AGNs’ power is thought to come from super-massive black holes at their centers that produce tremendous amounts of radiation from gravitational energy. In the process, matter falls into the black hole. But much of it (in the form of hot winds and high-energy jets) explodes away from the center, producing enormous luminosities.While quasars can look as if they are point-like stars, they can outshine all the stars in their galaxies by a factor of 100 to 1,000 times, making it difficult, if not impossible, to see the stars of the galaxy.Because the oldest quasars are so far away (for example, 12 billion light-years), we would never be able to see them if not for the tremendous power-producing abilities associated with their super-massive black holes. Some of these can weigh up to 10 billion times more than our star, the sun.Interestingly, the area that the AGN super-massive black hole occupies, from which its enormous power is created, is of relatively small size compared with its host galaxy.  An analogy used by the Chandra X-ray Center, for example, compares the compact central region to a small flashlight generating as much power as all of the homes and businesses in greater Los Angeles.With these key AGN characteristics in mind, the purpose of my research, titled “Optically Faint X-ray Selected Active Galactic Nuclei,” was to take certain astrophysics measurements of a sample of about 150 AGNs in the COSMOS field that had not been measured previously, as well as to perform more specialized analysis on a sample subset.Some of the basic findings of the research were that the sample AGNs are an average of 8 billion light-years away from Earth, which is typical for AGNs of this kind. The results from the overall sample also showed a correlation between luminosity and the quality of the sample fit. In addition, spectral analysis of the AGNs that contained oxygen and neon emissions lines indicated that star formation was taking place that would be consistent with current models of active galaxy evolution.During the summer, I learned that astrophysics research is very expensive and takes time (lots of it), in part because of the complexity of the questions being asked, the huge distances involved, and the precision that is essential to the process.Also, while much has been written about the field, the issue of how to approach the key questions of astrophysics is only indirectly discussed. The guidance and “handing down of knowledge” from mentors is a central tenet, without which one could not make the important connections necessary for true understanding.Much is written in the popular press about the need for collaboration and globalization. But in astrophysics, such cooperation is a norm, as evidenced by the many papers written with 10 or more colleagues around the world.Perhaps this close collaboration should not be surprising, since astrophysicists are among the few researchers trying to understand the very beginnings of the universe, its structural formations, and its likely future course. Then again, maybe it’s just fun getting to work with colleagues using a virtual time machine.last_img read more

Eclipse Safety

first_imgOn the afternoon of Aug. 21, Georgians will have the opportunity to share in the experience of seeing the summer afternoon sky darken as the moon’s shadow covers the sun, and they are excited.It’s going to be quite a show, but it’s important that eclipse viewers don’t get so caught up in the hype that they abandon safety, said Pam Knox, University of Georgia Cooperative Extension agricultural climatologist.It sounds obvious, but no one should look directly at the sun — even during the eclipse — without eclipse glasses from a reputable source, she said.“Even at 99 percent coverage, the sun is so strong that it can do some real, permanent damage to your eyesight,” Knox said. “No one should look at the eclipse without glasses.” Everyone in the continental United States will experience some level of solar eclipse on Aug. 21, but the total solar eclipse will be only visible in a wide swath stretching from Salem, Oregon, to Charleston, South Carolina.Only viewers in the very northeast corner of Georgia will see the sun completely blocked by the moon’s shadow. The rest of the state will see an 87 to 99 percent eclipse between 1 and 4 p.m. No matter where viewers are in the state, it is not safe to look at the sun without eye protection.Even occasional quick glances up at the sun can damage the eyes and cause burns to the retina — these cells at the back of the eye are responsible for processing light information. The damage, which appears as blurry spots in the field of vision, may be temporary, but very well could be permanent, according to NASA.gov.Eclipse-viewing glasses or solar shields are necessary to prevent eye damage. Dark or polarized sunglasses will not protect your eyes.“The eclipse glasses are so dark that if you put them on and look outside now, you wouldn’t be able to see anything,” Knox said. “If you can see anything through your eclipse glasses, they’re not strong enough.”Consumers should only buy glasses from reputable dealers. Earlier this summer, NASA.gov posted a list of eclipse glasses manufacturers that they have certified as safe. That list is available at eclipse2017.nasa.gov/safety.Consumers should be wary of noncertified glasses because there are a lot of fake eclipse-viewing classes out there this year, Knox said. Consider joining a group viewing party at an area park or nature center. Many schools and parks departments around the state and across the country will host organized eclipse-watching parties where they will provide glasses, eclipse shields or other safe ways of viewing the eclipse.Knox is helping to host UGA’s Eclipse Viewing Party at Sanford Stadium from 1 to 4 p.m. on Aug. 21. Sponsored by the UGA Athletic Association, UGA Atmospheric Sciences Program, Frankin College of Arts and Sciences and Department of Geography, the event includes disposable eclipse glasses that will be available for the crowd.Another option for safely watching the eclipse includes building an eclipse projector out of wood or cardboard. “Pinhole viewers” allow people to safely watch the projection of the eclipse on a piece of paper or board. NASA.gov features directions for some of these viewers and there are many other project tutorials online as well.For more information about eclipse safety and the path of the eclipse through Georgia, visit eclipse2017.nasa.gov/safety.

Sanders focuses on Vermont jobs in keynote speech at energy conference

first_imgUS Senator Bernie Sanders (I-VT) delivered the keynote address Tuesday at a conference on a cutting-edge Vermont initiative to improve energy efficiency, save consumers money and create good-paying jobs.Vermont was awarded $69 million in federal funds in 2009 to match an equal investment by the state’s utilities to develop a more efficient and more reliable electric system. The so-called smart-grid project will make Vermont the first state in the nation to provide high-tech meters in virtually all businesses and homes. By 2013, real-time information on energy consumption will let consumers make smarter choices.Sanders spoke at the conference hosted by the University of Vermont and Sandia National Laboratory, a world leader in energy research working with the state on implementation of the smart grid.‘I am excited about the partnership with the Sandia National Lab because of what that partnership can do to not only make us a leader in energy efficiency and sustainable energy but also in the process to create good-paying jobs for Vermonters,’ Sanders said afterward.A member of the Senate energy committee, Sanders has been instrumental in persuading the New Mexico-based national energy lab to open a New England satellite center at the University of Vermont.‘This is a big deal. We have before us an extraordinary opportunity â ¦ to be a leader for the nation,’ Sanders told the conference. ‘If we can pull off half of what I think we can, this will be a significant step forward.’A new Sandia-Vermont Center for Excellence would conduct advanced research that will bring the nation closer to energy self-sufficiency, increase energy efficiency, and develop a new green economy. This partnership will work with businesses and academic researchers to develop new technologies, new policies and new procedures.‘What Vermont offers Sandia, the Department of Energy, and the nation is a real-world model for this new research and technology,’ Sanders said.‘Over the long-term, this center will help create jobs and new educational opportunities for Vermont students and workers. It will make Vermont’s and America’s businesses more competitive both in the new technologies of the smart grid and locally distributed sustainable energy.’  Source: Sanders’ office. BURLINGTON, Vt., May 17, 2011last_img read more

Uruguay and the U.S. Train to Enhance Peacekeeping Missions

first_imgBy Dialogo August 14, 2015 Uruguay is a country with a population of less than 3.5 million, but is generally considered the top provider of peacekeeping Troops per capita in the world. Its Military is considered a worldwide leader in peacekeeping operations, as it continually provides Troops to many United Nations peace missions. The training helps service members perform tasks more efficiently and safely. “Our Army is fortunate. We live in a peaceful region, and deploying for peace missions presents a challenge,” said Uruguayan Army Colonel Carlos Frachelle, ENOPU’s director. “So receiving this training, which is the result of years of practical experience from U.S. personnel, is an opportunity we find to be very valuable.“The context of the peace missions is continually evolving; the operational environment is always changing. So, the challenges our personnel face are more and more complex,” he added. “Training courses like this help them perform these missions more effectively and efficiently, and will help avoid unnecessary risks and even save lives.” The training included debates as well as practical exercises, demonstrations, and events based on possible scenarios with the course culminating in closing ceremonies that gave students a chance to share experiences about what they learned. Varied and relevant training GPOI, which is a U.S. State Department assistance program executed by the Department of Defense, strives to enhance international capacity to effectively conduct United Nations and regional Peace Support Operations (PSO) by building partner nation capabilities to train personnel and sustain peacekeeping proficiencies. It also works to increase the number of capable Military Troops and Formed Police Units (FPU) available for deployments, in addition to facilitating the preparation, logistical support, and deployment of Military units and FPU to PSO. As of January 31, there were 1,459 Military and police personnel working in UN peacekeeping missions, including MINUSTAH, the UN Stabilization Mission in the Democratic Republic of the Congo (MONUSCO), the UN Mission in Liberia (UNMIL), the UN Military Observer Group in India and Pakistan (UNMOGIP), and the UN Operation in the Ivory Coast (UNOCI), according to the UN report “Troop and Police Contributors.” The dismantling of the base after eight years of service was an extended effort involving 80 service members working night and day for 28 days. The base’s closure coincided with a reduction in the contingent of Uruguayan service members at MINUSTAH. Uruguay began contributing Troops and police officers to MINUSTAH in June 2004, and at one point had four bases in Haiti. In 2010, after a magnitude 7 earthquake struck Haiti, killing an estimated 225,550 people, injuring 350,000, and leaving about 1.5 million people homeless, the South American country had 1,200 Troops in Haiti. The training developed in Uruguay improves the ability of service members to protect civilians during peace missions and is intended to reduce the need to use force, lowering the odds that a peacekeeping unit or civilians will be injured. Using behavioral indicators, peacekeeping forces are taught to identify those who could harm the general population. They also facilitate the protection of human rights. Other peacekeeping missions But after meeting the mission’s objectives, MINUSTAH’s command directed Uruguay to reduce its contingent from 700 to 250 in January 2015. center_img “It is imperative that the United States support [Uruguay’s] brave efforts in peacekeeping operations,” said U.S. Navy Lieutenant Commander Shannon Souma, in charge of the GPOI at the Office of Security Cooperation in Montevideo. Ninety percent of the service members in the Uruguayan Armed Force have or will participate in a foreign mission. Uruguay is participating in other international peacekeeping missions as well. Uruguay’s contribution to MINUSTAH Among those, is the UN Stabilization Mission in Haiti (MINUSTAH). As part of the MINUSTAH Military component’s draw down plan, Uruguayan service members closed the LTC Gonzalo Martirené Base in the commune of Mirebalais on February 4. “The service members’ operational environment is usually complex and often very dangerous,” Lt. Cmdr. Souma said. “It is really important for them to be able to identify potential threats so they can protect themselves and the civilian population. Ultimately, in the future, Uruguay will be able to train independently, and all service members will receive this training before leaving on a peace mission.” The course was developed by a team of experts from the U.S. Naval Research Laboratory who were led by one of the laboratory’s sociology professors, Nathan Meehan, Ph.D. Uruguay’s National School for Peace Operations (ENOPU) and human behaviorists from the United States who participate in the Global Peace Operations Initiative (GPOI) sponsored a training mission from July 13-17 in the South American nation for Soldiers who serve as international peacekeepers. The training program leverages the vast experiences of Uruguayan service members, some of whom have been on various missions, to create a course of instruction that prepares future service members efficiently. The training was also attended by a member of the Brazilian Army, as provided in the framework of the Latin American Association of Training Centers for Peace (ALCOPAZ), which in turn has facilitated the exchange of students and instructors with neighboring countries. The team’s principle tasks included conducting broad research on human behavior, including interviewing Uruguayan peacekeeping service members, during which researchers asked the service members to recount their experiences in peace operations to determine what types of behavior indicated potentially hostile intentions. “At this time, there are civilian, police, Navy, Air Force, and Army personnel filling a wide variety of functions,” Col. Frachelle said. “It is because of them that we can proudly say that we have a cumulative experience in peace missions that few countries possess.” last_img read more

PR Insight: The power of awards and the art of winning them

first_img 6SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr Five steps to increase your chancesby: Mary CoxReceiving an award – whether an industry award or local – can be extremely valuable for a credit union. Awards recognize excellence and validate the relevance and success of products, services, initiatives and even executives. They have the power to enhance a credit union’s image and strengthen visibility among members and potential members, thus increasing membership and loyalty.But securing an award can be challenging as competition tends to be fierce. Increase your chances of being selected by developing and executing a carefully crafted and strategic award campaign.1. Execute an Email and Social Media CampaignThere is an art to securing awards. While most require an application form, awards are often discussed by the association or publication months before the deadline. For these, credit unions should begin campaigning for the award early – before the award is officially announced.Develop an email and social media campaign that targets the award decision makers. Craft emails, tweets and posts that specifically speak to the reasons your credit union should be recognized. For example, if the award is recognizing credit unions that exemplify green initiatives, send regular updates about what your credit union is doing to be more eco-friendly. continue reading »last_img read more

Shelby relief bill to advance to full Senate

first_imgThe “Financial Regulatory Improvement Act,” a NAFCU-backed regulatory relief bill authored by Senate Banking Committee Chairman Richard Shelby, R-Ala., was approved by the committee in a party-line vote of 12-10 after mark-up on Thursday.The package, which Shelby first released last week, includes several NAFCU-backed provisions for credit union relief and transparency at NCUA. The bill would require public NCUA budget hearings and require the agency to study the impact of its risk-based capital proposal on mortgage servicing assets.Before the final committee vote, panel members approved an amendment from Sen. Pat Toomey, R-Pa., to raise the asset threshold for institutions subject to CFPB examinations from $10 billion to $50 billion. NAFCU supports this amendment, although the association has always advocated the exemption of all credit unions from CFPB regulation. Also added was a NAFCU-backed amendment from Sen. Mike Crapo, R-Idaho, to bar federal financial institution regulators, including NCUA, from participating in the Justice Department’s Operation Choke Point initiative.A substitute amendment to the bill from Ranking Member Sherrod Brown, D-Ohio, released Tuesday, was rejected along party lines, with 10 voting aye and 12 nay. continue reading » 7SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblrlast_img read more
