Heart rate and estimated energy expenditure of flapping and gliding in black-browed albatrosses

first_imgAlbatrosses are known to expend only a small amount of energy during flight. The low energy cost of albatross flight has been attributed to energy-efficient gliding (soaring) with sporadic flapping, although little is known about how much time and energy albatrosses expend in flapping versus gliding during cruising flight. Here, we examined the heart rates (used as an instantaneous index of energy expenditure) and flapping activities of free-ranging black-browed albatrosses (Thalassarche melanophrys) to estimate the energy cost of flapping as well as time spent in flapping activities. The heart rate of albatrosses during flight (144 beats min-1) was similar to that while sitting on the water (150 beats min-1). In contrast, heart rate was much higher during takeoff and landing (ca. 200 beats min-1). Heart rate during cruising flight was linearly correlated with the number of wing flaps per minute, suggesting an extra energy burden of flapping. Albatrosses expend only 4.6% ± 1.4% of their time in flapping during cruising flight, which was significantly lower than those during and shortly after takeoff (9.8% ± 3.5%). Flapping activity, which amounted to just 4.6% of the time in flight, accounted for 13.3% of the total energy expenditure during cruising flight. These results support the idea that albatrosses achieve energy-efficient flight by reducing the time spent in flapping activity, which is associated with high energy expenditure.last_img read more

The exercise will also permit to test and verify the interoperability of Spanish Navy warships with similar US and allied platforms.The main purpose of CSSQT is to assess and certify the ship’s combat system for command and control, anti-air warfare and anti-missile defense.The Spanish Navy said the qualification trials will conclude with the launching of Standard (SM-2) and Evolved Sea Sparrow (ESSM) missiles during three scheduled air defense exercises.The F-105 is the fifth of the AEGIS-equipped Spanish Navy frigates launched in 2010 and commissioned into active service in October 2012. Her crew consists of 201 sailors who perform humanitarian and peace-keeping missions in addition to conventional operations. The F-105 has participated in many international operations like ‘Ocean Shield’ and has been flagship of the Standing NATO Maritime Group Two (SNMG-2).center_img June 14, 2016 View post tag: Spanish Navy View post tag: Cristobal Colon View post tag: F-105last_img read more

Unprepared hikers rescued as winter-like conditions persist

first_imgAppalachian Trail hiker Christopher Lebel, 38, of Phippsburg, wrapped in a sleeping bag, walks out with assistance by rescuers through the woods to a waiting ATV. (Maine Warden Service photo)WELD – With the weather is still very much like winter on Maine’s mountains, emergency personnel were called Saturday night to rescue multiple people who were unprepared to hike in below freezing temperatures.The Maine Warden Service and emergency service personnel rescued one stranded family on Tumbledown Mountain in Weld, and in a separate incident, one severely hypothermic Appalachian Trail hiker in Township E.Wardens and emergency service personnel rescued a hiker on the Appalachian Trail Saturday who, rescuers said, likely would not have survived the night after falling into the water.Christopher J. Lebel, 38, of Phippsburg was hiking south with his dog on the Appalachian Trail in Letter E Township when approximately four miles into his trip, he fell into the water.Lebel changed his clothes but was unable to get warm and became severely hypothermic with temperatures below freezing, winds blowing, and ice and snow on the ground. Lebel was able to text a friend that he needed help, who in turn contacted 911 at 9:42 p.m. Saturday night. Game wardens and rescuers were able to take an ATV to get closer, then hiked through the woods to reach Lebel.Rescuers found Lebel unable to walk when they reached him. Wardens started a fire, provided hot liquids and food to Lebel, and were able to re-warm him to the point that he was able to walk out of the woods to the waiting ATV at approximately 4:30 a.m. Sunday morning.“Lebel did not have appropriate clothing or hiking gear for this time of year,” said Sgt. Scott Thrasher of the Warden Service. “Had Lebel been unable to send a text for help, it is unlikely he would have survived the night in the woods.”The Maine Warden Service was assisted in the rescue by members of the Rangeley Fire Department, U.S. Border Patrol and North Star EMS. Lebel was not transported to a hospital.In Weld, a family of five was also rescued on Saturday night after they had become stranded on the summit of Tumbledown Mountain.The family, Don Lantona, 53, Meena Latona, 52, Connor Latona, 18, Meaghan Latona, 20, and Ashley Latona, 22, all of Freehold, N.J., had climbed to the top of Tumbledown Mountain on Saturday. Due to the snow and ice at the summit, they could not find the trailhead to descend back down the mountain.With the sun going down, improper clothing, and not enough food, water or lighting to attempt to climb down the mountain, they called 911 at 6:46 p.m.Game wardens and first responders hiked up the mountain, where it was windy with temperatures in the low 30s. Upon reaching the summit, rescuers found the family huddled together for warmth. After starting a fire and warming members of the family, rescuers and the family hiked back down the mountain, getting to the base of the mountain approximately at midnight.“This family was not prepared for the conditions they experienced on this hike. There still is ice snow, and sub-freezing temperatures on the trails of many Maine mountains,” Thrasher noted. “These conditions can be extremely dangerous for those who are unprepared.”The Warden Service was assisted by members of the Weld Fire Department and Franklin Search and Rescue.last_img read more

Pressure mounts for Australian pension funds to divest fossil fuel holdings

first_img FacebookTwitterLinkedInEmailPrint分享Bloomberg:The world’s fourth-largest pension pot — with about $1.9 trillion — is facing mounting calls to ditch fossil fuels.UniSuper, which manages A$85 billion ($56 billion) in retirement savings for university researchers and academics in Australia, on Wednesday faced protests demanding the fund scrap investments in companies that are undermining the goals of the Paris climate agreement. The protests took place at a UniSuper-sponsored Universities Australia event in Canberra and coincided with a full-page advertisement from campaigners in the Australian Financial Review.UniSuper “is directly undermining our work and our future by driving climate change through its continued funding of fossil fuels,” Florian Busch, who researches carbon dioxide absorption in plants at the Australian National University, said in a statement.Offices of Health Employees Superannuation Trust Australia, known as HESTA, a fund managing A$55 billion in retirement savings for health and community services workers, also faced demands to take more action on climate change. Protesters occupied the building’s entrance in Melbourne on Wednesday to pressure it to divest of fossil fuels.The demonstrations are adding to pressure on custodians of Australia’s A$2.95 trillion retirement savings to catch up to peers like Europe’s Stichting Pensioenfonds ABP in cutting exposure to high-emitting companies. Those calls have gained traction after the nation’s deadly wildfires heightened concerns about the impact of climate change. Australia’s pensions industry has largely resisted exiting a whole segment of the economy amid pressure to meet minimum return targets. While funds have lifted investment in renewable energy projects, they also believe that by maintaining positions in climate-change offenders they can pressure companies to start altering their practices.[Matthew Burgess]More: Pressure mounts on Australia pensions to drop fossil fuels Pressure mounts for Australian pension funds to divest fossil fuel holdingslast_img read more

Operation ‘Project Nefarious’ arrests 637 members of 168 gangs

first_imgBy Dialogo April 27, 2012 WASHINGTON, D.C. — U.S. Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI) arrested 637 gang members and associates from 168 different gangs during Project Nefarious, an HSI-led operation executed in 150 U.S. cities and Honduras targeting transnational street, motorcycle and prison gangs involved with human smuggling and trafficking organizations. Project Nefarious began in February with threat assessments, intelligence gathering, information sharing and target identification, which resulted in enforcement operations from April 9 to April 21, ICE said on April 25. “By ridding our streets of 637 gang members and associates, we are putting a dent in the violence these transnational criminal street gangs bring to our communities,” said HSI Executive Associate Director James Dinkins. In addition to the arrests, during the operation special agents seized 52 firearms, 5,463 pounds of marijuana, 6.5 pounds of cocaine, US$201,437 in cash and 14 vehicles.
