Modeling the wave power distribution and characterisitics of plamaspheric hiss

first_imgWe simulate the spatial and spectral distributions of plasmaspheric hiss using a technique that involves extensive ray tracing. The rays are injected in the equatorial chorus source region outside the plasmasphere, are power weighted as a function of L-shell, frequency, and wave normal angle, so as to represent the chorus source distribution, and are propagated throughout the simulation domain until the power in each ray is effectivelyextinguished due to Landau damping. By setting up a large number of virtual observatories, the rays passing each observation location are counted, and a distribution isconstructed. Our simulated plasmaspheric hiss spectrum reproduces the main observed features, including the lower and upper frequency cutoffs, the behavior of the bandwidth as a function of L-shell, the spatial extent, and even the two-zone structure of hiss, although the intensity is lower than observed. The wave normal distribution shows that at high latitudes, the wave normals are predominantly oblique, but near the equator, the wave normal distribution can be either predominantly field-aligned (lower L shells), or bebimodal, having a maximum in the field-aligned direction, and another maximum at very oblique angles, comprised of those rays that have broken out of their cyclical trajectories. This distribution of wave normals seems to reconcile the apparently contradictory observations that have been reported previously.last_img read more

Royal Moroccan Navy’s FREMM Frigate Undergoes Sea Trials

first_imgBack to overview,Home naval-today Royal Moroccan Navy’s FREMM Frigate Undergoes Sea Trials View post tag: trials View post tag: Missiles Royal Moroccan Navy’s FREMM Frigate Undergoes Sea Trials The FREMM multimission frigate on order for the Royal Moroccan Navy is pursuing sea trials off the French coast in preparation for delivery later this year. In June, French naval shipbuilder DCNS successfully completed a third series of trials to test the performance of the ship’s combat system.The crew and DCNS specialists completed the latest trials off the Brittany coast. This series of tests was designed to check the performance of the combat system’s main sensors.Operational scenarios were executed to check the consistency of the data analysed and displayed by the combat system sensors with the results obtained during shore-based simulations. Specific tests included target engagement sequences using Aster anti-air missiles and MM40 anti-ship missiles, fire control tests for the 76-mm main gun and exhaustive testing of the multifunction radar. Other vessel capability tests involved helicopter approach control and the deployment of various towed devices. “This third series of sea trials represents a major milestone for the overall programme and more particularly for the ship’s combat system. Our crews thoroughly tested the full suite of combat system hardware and software that makes FREMM frigates among the most versatile and advanced on the world market”, says Gilles Raybaud, DCNS’s FREMM programme manager for Morocco.To acquaint them with shipboard operations, members of the crew that will take over once the vessel enters service with the Royal Moroccan Navy participated in the trials. Working in tandem with the French Navy crew, they took part in activities ranging from bridge and propulsion watchkeeping to safety exercises and platform management. The Moroccan crew members had previously completed simulation-based training at DCNS’s Lorient and Le Mourillon centres to familiarise them with the FREMM platform management systems.Vice-Admiral Laghmari, inspector-general of the Royal Moroccan Navy, toured the future Mohamed VI FREMM at Lorient, meeting members of the Moroccan crew assigned to the trials and congratulating them on the tasks already completed. He encouraged them to continue to familiarise themselves with the new ship prior to delivery, and indicated that he was fully satisfied with the programme’s progress and the results of the sea trials.The first series of sea trials, conducted in April, demonstrated the full compliance of the ship’s propulsion and navigation systems with the relevant performance requirements.FREMM, a major programme for DCNS and partnersThe French FREMM programme calls for 12 ships – 11 for the French Navy and one for the Royal Moroccan Navy.DCNS delivered the Aquitaine, the first FREMM multimission frigate, to the French Navy in November 2012.In accordance the contractual provisions, the second-of-type is scheduled for delivery to the Royal Moroccan Navy by the end of this year. The ship will be named the Mohammed VI.DCNS is currently working on four FREMM frigates at different stages of completion: third-of-type FREMM frigate Normandie will begin sea trials later this year and is scheduled fordelivery to the French Navy in 2014fourth-of-type FREMM frigate Provence is approaching completion and scheduled to be floated out of her building dock later this yearthe fifth and sixth of type are at earlier stages of construction.FREMM technical dataThese heavily armed warships are being built under DCNS prime contractorship to deploy state-of-the- art weapon systems and sensors including the Herakles multifunction radar, MdCN cruise missiles, Aster anti-air missiles, Exocet MM40 anti-ship missiles and MU90 torpedoes.Length overall: 142 mBeam: 20mDisplacement (approx.): 6,000 tonnesMax. speed: 27 knotsComplement: 108 (including helicopter crew)Accommodation: 145 men and womenRange: 6,000 nm (at 15 knots)[mappress]Press Release, July 11, 2013; Image: DCNS View post tag: Anti-ship Share this article View post tag: FREMM View post tag: Undergoes View post tag: Frigate View post tag: Royal View post tag: Moroccan July 11, 2013 Industry news View post tag: Navy View post tag: Naval View post tag: Multimission View post tag: Ministry of Defence View post tag: sea View post tag: News by topic View post tag: DCNSlast_img read more

Report The effect of peanuts on cholesterol and heart health

first_imgResearchers from California and Spain have concluded that regular peanut consumption improves cholesterol levels and contributes to heart health, following data collated from 25 nut consumption trials across seven countries.A total of 583 men and women took part in the trials, which revealed that people with higher levels of ’bad’ cholesterol (LDL) and triglycerides (blood fats) and those consuming poorer-quality diets, would gain the greatest benefit from regular nut consumption, according to the researchers.The studies showed those consuming the nuts frequently about 67g per day reduced their total cholesterol by 5.1% and LDL by 7.4%. Their ratio of LDL to ’good’ HDL cholesterol also changed by 8.3% in a favourable direction.Dr Joan Sabaté from Loma Linda University, California, lead investigator for the study, recently published in Archives of Internal Medicine, said: “Results of this study provide the best evidence yet that eating nuts reduces LDL cholesterol and improves the blood lipids profile. So a simple change of eating nuts regularly can make a big difference to people’s health.”Ellen Mason, a senior cardiac nurse with the British Heart Foundation, said that adding nuts in place of saturated fats could help to improve cholesterol levels for many people.last_img read more

Press release: Isle of Axholme to benefit from £35m flood protection investment

first_imgAndrew Haigh, the Environment Agency’s senior advisor for flood risk management, said: The contract to design and build the improved flood defence has been awarded to GBV, a joint venture between Galliford Try and Black & Veatch. The Isle of Axholme will benefit greatly from this £35m government funding which will better protect the local community and businesses from flooding for years to come. I am pleased to see the plan will not only bring more protection against flooding, but also have environmental benefits for wildlife and improve the health of the rivers in the area. I look forward to seeing the work completed. The £35m investment in a new state-of-the-art pumping station at Keadby will enable us to continue to protect over 15,000 homes, businesses and agricultural land from the risk of flooding across the Isle of Axholme. We have been working in partnership with the local authorities and the Internal Drainage Boards on our plans to upgrade the current facility with new electric pumps and equipment that will increase reliability and efficiency, leading to more effective water level management in this area. It also offers improved access for fish and eels to migrate between the ‘Three Rivers’ and the River Trent. An 80-year-old pumping station is to be given a new lease of life, bringing environmental and flood-risk benefits to an area almost twice the size of Birmingham, the Environment Agency has announced.The work is part of a £35m investment to upgrade Keadby Pumping Station near Scunthorpe and construction is set to get underway from mid-April. Preparation work on the site is currently underway.The improvements will see the facility’s diesel pumps replaced by more reliable and efficient electric versions. As well as reducing flood risk, the new pumps will also lessen the station’s carbon footprint and are designed to be safe for fish and eels.Keadby Pumping Station is used to manage water levels across the Isle of Axholme – around a 500 kilometre square area of North Lincolnshire, South Yorkshire and North Nottinghamshire.The facility helps reduce the risk of flooding by transferring flood water from the ‘Three Rivers’ into the River Trent during high tides.The Pumping Station reduces flood risk to more than 15,000 homes, 30,000 hectares of high-grade agricultural land, businesses, internationally important habitats, and critical infrastructure such as transport links, a power station and Doncaster Sheffield Airport.The current station has reached the end of its working life. The current pumps and equipment are unreliable, costly to maintain and are increasingly at risk of breaking down.The scheme also includes the construction of new electrical equipment buildings within the existing site and rebuilding of the outfall headwall, where the ‘Three Rivers’ discharges to the River Trent.The introduction of ‘fish-friendly’ pumps will mean both fish and eels can pass safely through the facility, helping them overcome man-made obstacles to their natural migration. The measure is recognised as vital to protecting wildlife and improving the health of rivers.Environment Minister Thérèse Coffey said:last_img read more

Come on Feel the Music

first_imgThat means you can run demanding, graphics-intensive applications like 3D rendering at the fastest speeds possible. And, if you’re a fan of the Linux operating system, you’ll be able to get that Precision 5720 preloaded with Ubuntu 16.04 LTS. Our “Project Sputnik” lead Barton George has more details on that in his blog.You don’t have to be a professional creator to want to amplify your experience, however.“Several self-described audiophiles that came through the booth at CES were surprised at how much better our system sounded compared to the iMac,” Peeler said.Just how much better? Well, it’s two times louder and with up to 50 percent better bass than the iMac 27.Want a closer look? Here’s a video overview of the XPS 27 AIO:&nbsp;</p><p> A lot of the talk heard around audio at #ces2017 earlier this month centered on things like sound bars, speakers and headphones. Cnet said “You could argue that, apart from the proliferation of Alexa speakers, there was a lack of any real innovation this year.”I guess their audio editor didn’t get to spend time in the sound booth at our #DellExperience pictured below. If they had, they would have seen, and heard, the Innovation Awards Honoree Dell XPS 27 All-in-One (far left). Hot Hardware called it “one of the fastest all-in-on PCs we’ve tested to date.” But the real innovation in this system isn’t speed – it’s sound.Hopefully you read award-winning record producer Jack Joseph Puig’s guest post here about how he spent 18-months with our designers, developers, engineers to create the XPS 27’s sound. But you probably haven’t seen the system used like The Glitch Mob showed us at the #DellExperience:&nbsp;</p><p>That was one of my favorite parts of the press event we held. (Sorry Tom Holland, you’re just too young for me.) To see our product in use so creatively excites me, and hearing it really excited others who stopped by the event.“More than the words they said, it was the facial expressions that conveyed ‘wow,’” said 20-year Dell audio veteran Doug Peeler who spent most of CES in that sound booth I mentioned. “You could see this emotion come over people when they would hear a song they liked and they would say ‘Man, it’s like I’m there.’”So while the new XPS 27 AIO, and its soon-to-come Precision business sibling, crank sound to a whole new level, Peeler says it’s less about decibels and more about feeling the music.“Factor in a 27-inch 4K touch display that can be laid flat, and you’ve got a spectacular all-in-one for artists, musicians or simply anyone who wants their content to both look and sound fantastic,” said Tom’s Guide when they named it “Best PC” in their CES 2017 Awards.Those creators are who our team had top-of-mind during years of development that led to this system’s audio. Six years ago Dell and Waves Audio started working together to create some of the greatest sounding laptops, but a meeting with Puig at the National Association of Music Merchants (NAMM) event brought his vision for a professional audio system together with Dell’s.“This is more like an actual reference monitor system that music producers use to make critical decisions on audio,” said Peeler.Such decision makers in the media and entertainment industry often use sophisticated software programs that demand an optimized workstation. And that is why we’re adding the first-ever all-in-one (AIO) to our Precision lineup – the number one workstation in North America according to IDC Worldwide Workstation Tracker Q3 2016.Precision 5720 AIO will have the same 10 speakers pumping out sound at 50W per channel and beautiful 4K Ultra HD (3840 x 2160) edge-to-edge touch display supporting 100 percent Adobe RGB color gamut as the XPS 27; but also more performance options with Intel Xeon processors, AMD Radeon Pro graphics capable of powering virtual reality and outstanding reliability with ISV certifications for top programs like AVID and SolidWorks, as well as leading security and manageability software.last_img read more

Berry sweet

first_imgBy Gerard KrewerUniversity of GeorgiaWith berry and grape farming expanding in Georgia, opportunitiesto harvest fresh strawberries, blueberries, blackberries andmuscadine grapes are getting easier to find.Harvesting your own berries and grapes is one of the realdelights of a day in the Georgia countryside. And picking berriesis an art you improve the more you harvest.Here are some tips to help make your farm forages more fruitfulwith the sweetest Georgia berries and grapes.Pick strawberries that are red ormostly red. A berry with a green tip will ripen, but the sweetestberries are those that are fully red at picking. Push back theleaves of the plant to reveal the succulent berries tucked intothe canopy.The sweetest blueberries are thosethat have been on the bush four or five days after they turnedblue. To identify those, hold your hands with the palms up andtickle the berry clusters containing a mixture of green and blueberries. The ripest fruit will drop into your hands.If you plan to keep the berries for a long time, pick all of theblue ones. Some of the fruit won’t be as sweet but will keeplonger. Hand-picked rabbiteye blueberries, the type most commonlygrown in Georgia, may last for three or four weeks in the fridge.The best blackberries are thosethat have gone from a shiny black to a dull black. You can pickdull black berries like blueberries: hold your hand under thefruit clusters and tickle them with your fingers to make theripest ones fall.The shiny black berries have a longer shelf life. To pick shinyblackberries, gently bend the fruit over until it snaps off.When you pick thorny blackberries, wearing latex gloves may helpreduce the number of thorns sticking in your hands. Look deepinside the canopy to find some of the best berries. You can use asmall stick to lift the thorny canes.Muscadine grape season will startin August. Muscadines are usually picked as individual berries.However, late in the season, clusters can be clipped off of somecultivars.Look for bronze grapes that have a bronze or greenish-bronzecolor. Some cultivars such as “Fry” are good whengreenish-bronze, while others should be fully bronze before youpick them. Black-fruited cultivars should be fully black.The fruit of all muscadines should be slightly soft beforeharvest.You can usually find the farmsselling berries by looking in the local newspaper’s classifiedads, calling your University of Georgia Extension Service countyoffice, reading the Farmers &Consumers Market Bulletin or contacting your local Farm Bureau office.(Gerard Krewer is an Extension Service horticulturist with theUniversity of Georgia College of Agricultural and EnvironmentalSciences.)last_img read more

Italian regulators okay Enel plan to close 605MW coal-fired unit at Brindisi plant

first_img FacebookTwitterLinkedInEmailPrint分享Argus Media:Italian utility Enel will shut down one of the four units of its 2.4GW Brindisi south coal-fired plant starting from next year.The Italian economic development ministry authorised the closure of the 605MW unit 2 from 1 January 2021, the company announced today. Enel presented the request in January this year as the first step towards shutting down the whole facility by 2025, aligned with the deadline set in the national energy and climate plan.The company also started the permitting process to convert the site to gas. This would be done in three phases. The first phase will be the installation of an open-cycle gas turbine (OCGT) unit and the phase-out of coal. The second phase will be the installation of a second OCGT, and the third phase will be to convert the OCGTs to combined-cycle gas turbines (CCGTs).The CCGTs will have an installed capacity of 1.7GW and an efficiency of 60pc.The move is part of a plan the company disclosed in May last year to replace its coal capacity in the country. Enel owns about 6.3GW of coal capacity in Italy — more than three-quarters of the total.[Fabio Roccon]More: Italy’s Enel to close one Brindisi coal unit in 2021 Italian regulators okay Enel plan to close 605MW coal-fired unit at Brindisi plantlast_img read more

Honduran Government Seeks Rapprochement with Unasur by Naming Ambassador

first_imgBy Dialogo August 04, 2010 Honduran president Porfirio Lobo’s administration announced Tuesday evening that jurist Jorge Arturo Reina has been named ambassador to the Union of South American Nations (Unasur). “Jorge Arturo Reina has been confirmed as a roving ambassador to handle all aspects of our relationship with all the Unasur countries,” foreign minister Mario Canahuati affirmed in statements to the press. Due to their close and friendly relations with deposed president Manuel Zelaya, the majority of Unasur countries have not recognized Lobo’s administration, which took office on 27 January. Lobo needs the support of the thirty-two other member countries of the Organization of American States (OAS) in order for Honduras to be reintegrated into the inter-American organization, from which it was suspended as a result of the 28 June 2009 coup d’état against Zelaya. Reina, known as a leftist political activist, has close ties to Zelaya, who even named him ambassador to the United Nations, despite the fact that the United States had cancelled his visa due to his ideological militancy.last_img read more
