Particle acceleration by fluctuating electricfields at a magnetic field null point

first_imgParticle acceleration consequences from fluctuating electric ields superposed on an X-type magnetic field in collisionless solar plasma are studied.Such a system is chosen to mimic generic features of dynamic reconnection, or the reconnective dissipation of a linear disturbance.Explore numerically the consequences for charged particle distributions of fluctuating electric ields superposed on an X-type magnetic field.Particle distributions are obtained by numerically integrating individual charged particle orbitswhen a time varying electric field is superimposed on a static X-type neutral point. This configuration represents the effects of the passage of a generic MHD disturbance through such a system.Different frequencies of the electric field areused, representing different possible types of wave. The electric field reduces with increasing distance from the X-type neutral point as in linear dynamic magnetic reconnection.The resulting particle distributions have properties that depend on the amplitude and frequency of the electric field. In many cases a bimodal form is found. Depending on the timescale for variation of the electric field, electrons and ions may be accelerated to different degrees and often have energy distributions of different forms. Protons are accelerated to gamma-ray producing energies and electrons to and above hard X-ray producing energies in timescales of 1 second. The acceleration mechanism is possibly important for solar flares and solar noise storms but is also applicable to all collisionless plasmas.last_img read more

Redknapp looks to transfer window

first_img Redknapp believes chairman Tony Fernandes will back him in the transfer market provided the Hoops are not way off the pace in the relegation scrap. “We are trying, we felt we have to make sure we are still in there,” Redknapp said on talkSPORT. “If you are cut adrift at Christmas, you don’t want to be going and getting yourself into trouble, but if we are still in there with a chance, which I think we will be, then the chairman will go out and let us get one or two players who could make the difference for us. “We have got one or two targets, and are just waiting to see if we can get them over the line.” QPR, who drew 2-2 at home with champions Manchester City before the international break, host Newcastle on Saturday, with the Magpies now very much on the up having at one time looked set for a survival battle themselves. Redknapp added “I look at the table and think there are going to be seven or eight teams involved in that scrap. “Burnley had a win last week, there is no-one cut adrift yet, it is too early, and if anyone could get back-to-back wins like Newcastle have done, it could all turn quickly. “We brought a few new players in and it took them time to settle, but they are finding their feet at the club now. “I think we we have deserved more points with the form we are in, but I would rather play poorly and pick up a few wins.” Queens Park Rangers manager Harry Redknapp is hoping to bring in some new additions when the January transfer window opens who “could make the difference” in terms of Barclays Premier League survival. The west London club, promoted back to the top flight after winning the Sky Bet Championship play-off at Wembley, are second from bottom of the table, but only a point behind 17th-placed Crystal Palace. QPR have been linked with a move for former England striker Jermain Defoe, who is with Toronto in the Major Soccer League. center_img Press Associationlast_img read more

Microsoft Rolls Out Office Web Apps

first_imgIT + Project Management: A Love Affair 3 Areas of Your Business that Need Tech Now Tags:#enterprise#news#Products Microsoft rolled out Microsoft Office Web Apps on Skydrive to users in the U.S., U.K., Canada and Ireland yesterday.

However, we found that we were able to create and save documents from Chrome on a Windows 7 desktop.This offering will doubtlessly bring comparisons with Google Docs. Office Web Apps feels quite similar, and is at least as functional as Google Apps but is lacking in major functionality, such as the ability to create charts and graphs in Excel (see comments below).The on-premise option, desktop integration, and the familiar features and interface of Microsoft Office, makes Office Web Apps a strong competitor against Google’s Google Apps and ZoHo as they market their office in the cloud solutions to the enterprise.Last month, Pascal-Emmanuel Gobry writing for Business Insider, called on Google to buy to improve their enterprise penetration. “Google Docs just can’t compete with Microsoft Office on features, and while it’s better at collaboration, that advantage will vanish as Microsoft moves these features to the cloud,” he wrote.Many other analysts disagreed, citing Google and Salesforce’s radically different corporate cultures.

ConocoPhillips fined 180000 for 2016 leak of condensate in northwest Alberta

first_imgCALGARY – Oil and gas producer ConocoPhillips Canada is being fined $180,000 for a 2016 pipeline leak that spilled a light petroleum liquid into a remote area of northwestern Alberta.The leak of 380,000 litres of condensate resulted in 38 observed fatalities to unspecified species of wildlife and hundreds of potential wildlife deaths as it affected nearly three square kilometres of land as well as nearby waterways, the Alberta Energy Regulator said on its website.The AER assessed a $165,000 fine against the Canadian arm of Houston-based ConocoPhillips Co. to account for the 33 days in May and June 2016 that the company failed to report the release to the regulator as it should have.It also fined the company $5,000 each for three counts related to failing to develop and maintain a leak-detection manual for the pipeline, failing to take reasonable measures to remedy and confine the leak and for allowing the release to damage public land.Not noticing the leak when it began and then not reporting it immediately made worse environmental damage that included the loss of all fish spawning output in Webb Creek for the year, said AER director Mark Miller in his decision posted on the website.“The failure to report and take remedial actions as soon as ConocoPhillips ought to have known very likely resulted in a greater degree of adverse effects to the environment that could have been mitigated if dealt with sooner,” said Miller.The company has received the AER’s notice and is reviewing it, said spokeswoman Katherine Springall.She said clean-up activities at the spill site began when it was discovered in 2016 and the company has since worked closely with the AER to mitigate environmental impacts.The asset was included as part of a package sale to Cenovus Energy Inc. in 2017, she added, with responsibility for any remaining remediation transferred along with ownership.The leak took place near ConocoPhillips’ Resthaven gas plant about 65 kilometres northeast of Grande Cache, Alta.Staff noticed lower pressure in the pipeline but couldn’t see a leak right of way because the condensate had travelled underground to a less visible area, Miller said in his decision.They concluded wrongly that the lower pressure resulted from overnight ambient temperature changes and minor leaks from inlet and outlet valves on the pipeline, he noted.Follow @HealingSlowly on Twitter.Companies in this article: (TSX:CVE)last_img read more

HRD to implement 10 quota for general category sans funds

first_imgNew Delhi: The government’s decision to implement 10 per cent reservation for economically weaker sections of the general category may cost dearer to the public institutions as the Human Resource Development (HRD) Ministry has put on hold the fund allocation procedure to higher institutions for meeting the expenses to be incurred in implementing the quota.The HRD Ministry’s proposal to provide financial assistance of about Rs 4,000 crore has been stuck in the model code of conduct. As per official sources, the ministry in its communication with institutions has stated that the proposal would be approved only after the formation of the government and till then the institutions would have to bear the additional expenditure of their own. Also Read – Uddhav bats for ‘Sena CM’Citing the enforcement of model code of conduct due to ongoing general elections in the country, sources in the HRD Ministry said, “Given the value of the amount, the Election Commission is reluctant in approving the proposal.” The sources further that the EC is reluctant in permitting the HRD ministry to provide funds to institutions as the proposal has not been passed by the Cabinet. The sources also said that institutions would have to implement the quota without any dedicated funds for it.

Soon after the decision, the HRD Ministry had announced that it would increase 25 per cent seats in all higher education institutions to accommodate the beneficiaries of 10 per cent quota to poor upper caste without disturbing seat share of other reserved categories. The HRD Ministry had also sought details from higher institutions about the financial burden on them for increasing 25 per cent seats. As per the HRD officials, all higher institutions, including IITs, IIMs, Central universities, NITs, IISER, had sought Rs 5,676 crore financial support for creating 2.15 lakh additional seats.last_img read more

Indian eves beat Malaysia 30 in series opener

first_imgKuala Lumpur: Striker Vandana Katariya scored a brace to help Indian women’s hockey team beat hosts Malaysia 3-0 in the opening game of the five-match series here on Thursday. Vandana struck in the 17th and 60th minutes before Lalremsiami (38th) scored in the third quarter to hand India the easy win. It was Malaysia who got a head start with a penalty corner in the third minute of the match, but it was well-saved by an experienced Savita guarding the Indian goalpost.

Two minutes later, Navneet Kaur attempted a shot on goal but was denied by an alert Malaysian goalkeeper. Soon India got a penalty corner but the resultant try went wide. After a goalless first quarter, India broke the deadlock in the 17th minute when Vandana scored a fine field goal. With a one goal cushion, India maintained a good structure and controlled the proceedings in the third quarter too. The Indians kept the Malaysian attack in check and under pressure the hosts conceded three penalty corners but all the chances went in vain. India doubled their lead in the 38th minute through another field strike by young striker Lalremsiami. The 2-0 lead put India in a comfortable position in the fourth quarter and the visitors increased their lead just seconds from the final hooter through Vandana.
