MS Dhonis number 7 jersey to be retired Indian players might not


first_imgIn the upcoming Test championship, players will sport their numbers and name on the back of their white shirt. However, when it comes to the Indian team, it will not see two numbers – 10 and 7. While number 10, which is Sachin Tendulkar’s jersey, has been unofficially retired by the BCCI, MS Dhoni’s number 7 jersey might also not be opted for by the players.It is now learnt that most of the Indian players will opt for their limited-overs jersey numbers.”Virat is expected to wear 18 while Rohit wears 45. Most of the players will wear their respective ODI and T20 numbers. Since MS is no longer playing Test cricket, jersey No.7 is available but there is very little chance that any of the players will wear it,” a senior BCCI official told PTI on condition of anonymity.’BCCI’s gesture to pay tribute to Dhoni’ MS DhoniHannah Peters/Getty Images”People relate jersey No 7 with MS. The consignment of numbered jerseys will only arrive in the Caribbean only after ODI series,” he further added.It should be mentioned here, that a jersey cannot be officially retired, but the BCCI could opt for a move which pays respect to a player of MS Dhoni’s stature in Indian cricket. As far as his international career is concerned, the former Indian captain is not part of India’s limited-overs squads for the West Indies tour. There are speculations over his retirement, but statements by few BCCI officials have suggested that the wicket-keeper is not yet keen to move on.Former Indian captain Mohammad Azharuddin too said that communication between the selectors and Dhoni will be vital as he enters the final lap of his career.”About big player, the player is also taken into confidence and spoken to. I feel some decision will come. Otherwise, people will keep writing that (he) should retire, not retire. Because, no statement has come from Dhoni,” Azhar said. File photo of MS DhoniSydney Seshibedi/Gallo Images/Getty ImagesHe also said that if the wicket-keeper batsman is fit and wants to continue playing, he should be backed to come good.”My opinion is that if he is fit and playing well, he should play. If he is fit and performance is good, he can play. Sometimes what happens is, interest is lost after playing so much cricket. If his interest is still 100 per cent, I feel, he is good player and he should play,” he further added.Even as the Indian team travels to West Indies, Dhoni has opted to train with the Territorial Army battalion of the parachute regiment and this request has been approved by Indian Army chief Bipin Rawat.last_img read more


Trump plans to declare national emergency


first_imgIn this file photo taken on February 12, 2019 US President Donald Trump speaks during a cabinet meeting in the Cabinet Room of the White House in Washington, DC as Deputy Secretary of State John Sullivan (L) and Commerce Secretary Wilbur Ross(R) look on. Photo: AFPPresident Donald Trump plans to declare a national emergency to fund his controversial border wall, the White House said Thursday, a move that alarmed US lawmakers shortly before they passed legislation to avert a government shutdown.Trump has signaled he will sign the massive spending measure keeping federal agencies operational through 30 September.But it does not specifically fund a wall on the US-Mexico border, and Trump’s emergency declaration would help him bypass Congress to locate and redirect billions of dollars in funding to build it.Trump will take the action “to ensure we stop the national security and humanitarian crisis at the border,” White House press secretary Sarah Sanders said shortly before the Senate passed the spending bill.The House of Representatives followed suit hours later, and Trump has until a midnight Friday deadline to sign it and prevent the government from going into shutdown for the second time this year.Signing the spending bill would bring an end to a rolling, two-month battle over government funding. But by declaring an emergency, Trump opens a new confrontation — and creates some of the riskiest legal peril of his term.House Speaker Nancy Pelosi, Trump’s Democratic nemesis in Congress, said members of her caucus were “reviewing our options” about how to respond to Trump’s move.”Declaring a national emergency would be a lawless act, a gross abuse of the power of the presidency and a desperate attempt to distract from the fact that president Trump broke his core promise to have Mexico pay for his wall,” Pelosi and senate minority leader Chuck Schumer said in a statement.Senate majority leader Mitch McConnell said he backs the president, but several others in the Republican camp have expressed deep reservations.”I have concerns about the precedent that could be set with the use of emergency action to re-appropriate funds,” veteran Republican senator Chuck Grassley said in a statement.Senator Susan Collins said it “would be a mistake on the part of the president” to declare such an emergency, warning it would “undermine” lawmakers’ all-important role as financial appropriators.Many lawmakers have said they have no idea from where Trump will draw the funding. Democrats in particular have signaled that the move would open the door to future presidents declaring emergencies on various topics, from gun violence to climate change to the opioid crisis.Court challenges likelyUnder the National Emergencies Act, the president can declare a national emergency, providing a specific reason for it.That allows the mobilization of hundreds of dormant emergency powers under other laws, which can permit the White House to declare martial law, suspend civil liberties, expand the military, seize property and restrict trade, communications and financial transactions.Trump has repeatedly stated he will look to other federal sources to fund his wall, one of his top campaign trail promises from 2016.There is broad expectation that Trump’s move would be challenged in court.And house judiciary committee Jerry Nadler expressed support for a joint congressional resolution to “terminate” Trump’s emergency declaration.That resolution would likely pass the Democratically-controlled House, but it would face a tough road in the Senate, where several Republicans may not wish to cross the president.Even if it passed, Trump could veto it.The spending measure includes only $1.375 billion for border barriers or fencing, far from the $5.7 billion that Trump has sought for his long-promised border wall — a demand that led to the recent 35-day government shutdown, the longest in US history.The compromise package funds until 30 September the 25 per cent of the government whose operations would lapse if the bill is not signed by Trump by the midnight Friday deadline.Pelosi expressed disdain for the president’s upcoming emergency declaration, warning that he was doing “an end run around Congress.””It’s not an emergency, what’s happening at the border,” she said in comments echoed by multiple Democratic lawmakers.Conservative ireTrump is widely seen to have suffered politically more than Democrats over the previous shutdown fight.But he also needs to assuage conservatives livid that the president retreated from his wall-funding demand, a longtime campaign pledge.”This bill must NOT be signed by @realDonaldTrump,” tweeted Fox News host Laura Ingraham, warning it would serve as a “stimulus” for illegal immigration in part because it puts limits on law enforcement’s ability to deport some undocumented immigrants.The bipartisan spending measure, negotiated for weeks, notably does not contain the word “wall” in its 1,165 pages, instead calling the structures physical barriers and pedestrian fencing.last_img read more


Biologist suggests carbon monoxide as an energy source for microbes on Mars


first_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. In order for life to have existed on Mars (or if it still does in a place we have not found yet) it would have to have an energy source of some kind. Prior research has suggested such a source might be nitrogen, the same energy source for most plants here on Earth—a recent report by researchers studying data from Curiosity rover, describes nitrates found in the soil. In this new effort, King takes a different approach, he believes that carbon monoxide may hold the key to life on Mars.King took soil samples from three places here on Earth that have very dry climates and very salty soil, the Atacama desert in Chili, the Bonneville Salt Flats in Utah and a part of the big island in Hawaii. In studying the samples, he found that the soil did indeed pull carbon monoxide out of the air and held onto it. He suggests the same process could occur on Mars, as its atmosphere has more carbon monoxide in it than does ours. He goes further to suggest that the mysterious, recurring slope lineae—dark streaks that change color seasonally on Mars, might be due to carbon monoxide being pulled into the soil. He believes that carbon monoxide could represent the missing piece in the search for life on Mars: the energy source. As evidence of the possibility, he points out two microbes (Halorubrum str. BV1 and Alkalilimnicola ehrlichii MLHE-1) that live on Earth that use carbon monoxide as an energy source, one of which has also been shown able to tolerate salt concentrations that are similar to those found in Martian soil.Unfortunately, there is no mechanism for testing King’s ideas, neither of the rovers on Mars has the equipment needed for that kind of test. He will have to wait until 2021, when NASA plans to send a probe to the Red planet that is capable of detecting microbes in the soil. Explore further Valles Marineris, Mars. Credit: NASA (Phys.org)—Gary King, a biologist at Louisiana State University has put forth the idea that if life did exist on Mars, it very possibly could have survived by using carbon monoxide. In his paper published in Proceedings of the National Academy of Sciences, he discusses his study of microbes in soil samples collected here on Earth that are able to pull in carbon monoxide and why it might relate to life on Mars. Journal information: Proceedings of the National Academy of Sciencescenter_img More information: Carbon monoxide as a metabolic energy source for extremely halophilic microbes: Implications for microbial activity in Mars regolith, Gary M. King, PNAS, DOI: 10.1073/pnas.1424989112AbstractCarbon monoxide occurs at relatively high concentrations (≥800 parts per million) in Mars’ atmosphere, where it represents a potentially significant energy source that could fuel metabolism by a localized putative surface or near-surface microbiota. However, the plausibility of CO oxidation under conditions relevant for Mars in its past or at present has not been evaluated. Results from diverse terrestrial brines and saline soils provide the first documentation, to our knowledge, of active CO uptake at water potentials (−41 MPa to −117 MPa) that might occur in putative brines at recurrent slope lineae (RSL) on Mars. Results from two extremely halophilic isolates complement the field observations. Halorubrum str. BV1, isolated from the Bonneville Salt Flats, Utah (to our knowledge, the first documented extremely halophilic CO-oxidizing member of the Euryarchaeota), consumed CO in a salt-saturated medium with a water potential of −39.6 MPa; activity was reduced by only 28% relative to activity at its optimum water potential of −11 MPa. A proteobacterial isolate from hypersaline Mono Lake, California, Alkalilimnicola ehrlichii MLHE-1, also oxidized CO at low water potentials (−19 MPa), at temperatures within ranges reported for RSL, and under oxic, suboxic (0.2% oxygen), and anoxic conditions (oxygen-free with nitrate). MLHE-1 was unaffected by magnesium perchlorate or low atmospheric pressure (10 mbar). These results collectively establish the potential for microbial CO oxidation under conditions that might obtain at local scales (e.g., RSL) on contemporary Mars and at larger spatial scales earlier in Mars’ history.

Musical lessons for Sarah Jane


first_imgTaking her passion for music a step forward, actress-singer Sarah Jane Dias is learning the acoustic guitar to hone her musical skills. “I always had a nag to learn an instrument since my childhood. However, I never got to do so… I believe that learning of any kind of music…be it instrumental or vocal… enhances your ability as an artist,” Sarah Jane said in a statement. She is taking vocal lessons from Samantha Edward and instrument from a Parsi musician. The former Miss India, who released her first single Forgot to be me on Valentine’s Day this year, shared that she is an ‘obedient student’. “I’m very happy to have found someone who has learnt the art of acoustic guitar from the golden era of guitar. I’m an obedient student,” she added.last_img


New programming video courses for March 2019


first_imgIt’s not always easy to know what to learn next if you’re a programmer. Industry shifts can be subtle but they can sometimes be dramatic, making it incredibly important to stay on top of what’s happening both in your field and beyond. No one person can make that decision for you. All the thought leadership and mentorship in the world isn’t going to be able to tell you what’s right for you when it comes to your career. But this list of videos, released last month, might give you a helping hand as to where to go next when it comes to your learning… New data science and artificial intelligence video courses for March Apache Spark is carving out a big presence as the go-to software for big data. Two videos from February focus on Spark – Distributed Deep Learning with Apache Spark and Apache Spark in 7 Days. If you’re new to Spark and want a crash course on the tool, then clearly, our video aims to get you up and running quickly. However, Distributed Deep Learning with Apache Spark offers a deeper exploration that shows you how to develop end to end deep learning pipelines that can leverage the full potential of cutting edge deep learning techniques. While we’re on the subject of machine learning, other choice video courses for March include TensorFlow 2.0 New Features (we’ve been eagerly awaiting it and it finally looks like we can see what it will be like), Hands On Machine Learning with JavaScript (yes, you can now do machine learning in the browser), and a handful of interesting videos on artificial intelligence and finance: AI for Finance Machine Learning for Algorithmic Trading Bots with Python Hands on Python for Finance Elsewhere, a number of data visualization video courses prove that communicating and presenting data remains an urgent challenge for those in the data space. Tableau remains one of the definitive tools – you can learn the latest version with Tableau 2019.1 for Data Scientists and Data Visualization Recipes with Python and Matplotlib 3. New app and web development video courses for March 2019 There are a wealth of video courses for web and app developers to choose from this month. True, Hands-on Machine Learning for JavaScript is well worth a look, but moving past the machine learning hype, there are a number of video courses that take a practical look at popular tools and new approaches to app and web development. Angular’s death has been greatly exaggerated – it remains a pillar of the JavaScript world. While the project’s versioning has arguably been lacking some clarity, if you want to get up to speed with where the framework is today, try Angular 7: A Practical Guide. It’s a video that does exactly what it says on the proverbial tin – it shows off Angular 7 and demonstrates how to start using it in web projects. We’ve also been seeing some uptake of Angular by ASP.NET developers, as it offers a nice complement to the Microsoft framework on the front end side. Our latest video on the combination, Hands-on Web Development with ASP.NET Core and Angular, is another practical look at an effective and increasingly popular approach to full-stack development. Other picks for March include Building Mobile Apps with Ionic 4, a video that brings you right up to date with the recent update that launched in January (interestingly, the project is now backed by web components, not Angular), and a couple of Redux videos – Mastering Redux and Redux Recipes. Redux is still relatively new. Essentially, it’s a JavaScript library that helps you manage application state – because it can be used with a range of different frameworks and libraries, including both Angular and React, it’s likely to go from strength to strength in 2019. Infrastructure, admin and security video courses for March 2019 Node.js is becoming an important library for infrastructure and DevOps engineers. As we move to a cloud native world, it’s a great tool for developing lightweight and modular services. That’s why we’re picking Learn Serverless App Development with Node.js and Azure Functions as one of our top videos for this month. Azure has been growing at a rapid rate over the last 12 months, and while it’s still some way behind AWS, Microsoft’s focus on developer experience is making Azure an increasingly popular platform with developers. For Node developers, this video is a great place to begin – it’s also useful for anyone who simply wants to find out what serverless development actually feels like. Read next: Serverless computing wars: AWS Lambda vs. Azure Functions A partner to this, for anyone beginning Node, is the new Node.js Design Patterns video. In particular, if Node.js is an important tool in your architecture, following design patterns is a robust method of ensuring reliability and resilience. Elsewhere, we have Modern DevOps in Practice, cutting through the consultancy-speak to give you useful and applicable guidance on how to use DevOps thinking in your workflows and processes, and DevOps with Azure, another video that again demonstrates just how impressive Azure is. For those not Azure-inclined, there’s AWS Certified Developer Associate – A Practical Guide, a video that takes you through everything you need to know to pass the AWS Developer Associate exam. There’s also a completely cloud-agnostic video course in the form of Creating a Continuous Deployment Pipeline for Cloud Platforms that’s essential for infrastructure and operations engineers getting to grips with cloud native development. Learn a new programming language with these new video courses for March Finally, there are a number of new video courses that can help you get to grips with a new programming language. So, perfect if you’ve been putting off your new year’s resolution to learn a new language… Java 11 in 7 Days is a new video that brings you bang up to date with everything in the latest version of Java, while Hands-on Functional Programming with Java will help you rethink and reevaluate the way you use Java. Together, the two videos are a great way for Java developers to kick start their learning and update their skill set.last_img read more
