Mrs. Fonnie had more than 30 years of experience treating Lassa fever, a hemorrhagic illness with many symptoms similar to Ebola, and specialized in the management of severe Lassa cases in pregnant women. She began her career working at Nixon Memorial Methodist Hospital in Segbwema, Sierra Leone, and participated there in Lassa fever research trials conducted by the Centers for Disease Control and Prevention. “Aunty Mbalu was a mother figure to the entire staff,” Garry says. She had survived Lassa fever. She was infected with Ebola while caring for one of her fellow nurses, who was pregnant and had Ebola. Sidiki Saffa, who died of a stroke unrelated to Ebola while the paper was in press, was a laboratory technician who collected blood samples and processed them. Mr. Saffa had more than 20 years of experience collecting blood samples from Lassa fever patients. “Very well organized and great with the record keeping … [he was] always on the move from the clinic to the laboratory and back,” Garry says. “He was the lifeblood of the operation.”*The Ebola Files: Given the current Ebola outbreak, unprecedented in terms of number of people killed and rapid geographic spread, Science and Science Translational Medicine have made a collection of research and news articles on the viral disease freely available to researchers and the general public. The ongoing Ebola virus disease outbreak is taking an appalling toll on health workers in West Africa. More than 240 have been infected and more than 120 have died. At Kenema Government Hospital (KGH) in Sierra Leone, where the country’s first case was diagnosed, more than 2 dozen nurses, doctors, and support staff have died of Ebola. KGH is where many of the samples were collected for a paper published online today in Science that analyzes the genetics of the virus responsible for the disease. Highlighting the danger to those caring for infected people, five of the paper’s co-authors—all experienced members of the hospital’s Lassa fever team—died of Ebola before its publication. (A sixth co-author, uninfected, also recently died as well.) Sheik Humarr Khan was the director of the national Lassa fever program for the Ministry of Health and Sanitation in Sierra Leone and an expert on treating viral hemorrhagic fevers like Lassa fever and Ebola virus disease. He studied medicine at the University of Sierra Leone and completed a residency in internal medicine at Korle Bu Teaching Hospital in Ghana. He worked with the African Centre of Excellence for Genomics of Infectious Disease, the Human Heredity and Health in Africa Initiative, and was a founding member of the Viral Hemorrhagic Fever Consortium. Khan had treated Lassa fever patients for more than 10 years. At the time of his death, he was helping coordinate his country’s response to the Ebola outbreak. Widely respected by colleagues, President Ernest Bai Koroma hailed him as a “national hero.” His death sparked widespread discussion about whether he should have been treated with the untested drug ZMapp. “I will miss his smile and good nature, and will always admire his exceptional bravery, loyalty, and strength,” writes Pardis Sabeti of the Massachusetts Institute of Technology, who led the published genetics study, in a tribute page dedicated to Dr. Khan. Mohamed Fullah, a laboratory technician who helped on the study, was an instructor at Eastern Polytechnic College in Sierra Leone, where he served for more than 10 years. Extremely popular with his students, Mr. Fullah had worked part time in the Lassa fever laboratory for 6 years. Mr. Fullah was intense, disciplined, and very hard-working, Garry says. He was “very dedicated and serious about the laboratory and science in general.” He lost several of his close family members to Ebola and presumably contracted the disease from one of them.center_img CREDIT: Kelly Krause, AAAS Alice Kovoma was helping Mrs. Fonnie treat the pregnant nurse when she, too, became infected. A Lassa Ward nurse for more than 6 years, Ms. Kovoma was “a wonderful person … very dedicated and professional with a devotion to the patients and her teammates,” Garry says. Alex Moigboi, a registered nurse with more than 10 years of experience caring for Lassa fever patients, was also infected while treating the same colleague. Mr. Moigboi “loved to interact and raise everyone’s spirits with his great sense of humor,” Garry says. “Always with a smile on his face … the last one off the dance floor.”last_img read more

A DIY project to monitor Internet downtime

first_imgShare this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Communications, Industry, Solutions These days, having access to the Internet is almost as necessary as having access to food and water. Without the Internet, many activities like worldwide communication, journalism, education, business, and financial operations would simply stop working. But, what if your Internet connection is less than perfect? How can Internet quality be measured or defined?This article describes a project to measure Internet connection quality by counting total network downtime. The project’s features are as follows:Use the ThingSpeak platform to display continuously measured downtimes.When a downtime event occurs, automatically send a Tweet to your Internet provider to alert them regarding the failure in your Internet connection.Register a report of all downtimes that exceed a certain specified limit.This project can also be run using a headless approach if you so desire.Requirements In order to replicate this project, you will need an understanding (at a basic-intermediate level) of the following topics:Embedded Linux (command line interface, basic commands, file system structure, and text editors).The Python programming/scripting language.Basic knowledge of computer networks.At a minimum, you should have heard about ThingSpeak and Twitter. If not, then this would be a really good time to start Googling them.Regarding the hardware, this project was developed on a Raspberry PI, but it can be easily ported to any single-board computer (SBC) that supports Embedded Linux distro, Python programming, and some form of Internet connection. This means that this project will easily work on a BeagleBone Black, a BeagleBone Green, a Linit Smart 7688, and… the list goes on.Note that the remainder of this article assumes that you already have full access to a single-board computer via a physical keyboard, mouse, and monitor (or by SSH and/or VNC access).What is Internet connection downtime? When we talk about Internet connection downtime, we are referring to the total time an Internet connection is not available — the more the Internet goes down, the greater is the total downtime. Thus, Internet connection quality is inversely proportional to total downtime.Ok, but what can I do with downtime measurement? Well, this depends on where you live and your local laws and regulations. In Brazil, for example, there is a regulatory agency for telecommunication issues called ANATEL (this stands for Agência NAcional de TELecomuniações in Portuguese). In resolution number 514/2013 (article 46), ANATEL specifies that every Internet service interruption with a duration greater than 30 minutes will result in in proportional discounts on the Internet provider’s bill. Therefore, claiming discounts due to poor Internet service is a very good usage for downtime measurement, and also a good way to drive Internet providers to increase their service quality.So, how can a downtime be determined? Based on our earlier discussions, you should now be comfortable talking about downtime and what it represents with regard to Internet connection quality measurement, so now it’s time to begin the project itself.First, we need to define a method with which to measure downtime. The most intuitive and logical method is to periodically ping a reliable server. Actually, I bet almost everyone has done this to check Internet connectivity at least once!Ping test to check the Internet’s availability (Source: Pedro Bertoleti) This sounds simple and obvious, right? But, not so fast: the time interval between pings matters A LOT! The reason for this is that, if the time interval between two pings is too short, then your IP address may be blocked by the server you’re pinging. This blocking policy makes sense, because multiple pings too close together might indicate a very, very simple DDoS attack (even though pings sound silly for a DDoS attack). So, to avoid the risk of being blocked, a good time interval between two ping/ICMP requests is 20 seconds. Of course, this implies that any downtime measurement will be equal to the number of consecutive downtimes (unanswered pings) multiplied by 20 seconds.In my opinion, one of the most reliable servers for doing this is Google’s DNS server (the famous This choice was made based on two facts as follows:This DNS server is one of the most used DNS servers worldwide, which leads to the that highly stable and reliable. Due to its heavy usage, we can infer that it has almost no downtime.The number of requests each day is huge! To figure out how huge, just imagine almost every computer, smartphone, and tablet in the world requesting Googles DNS’s service to browse webpages. It’s massive! Considering this, the chance of a project like ours being blocked by continuous access is minimal.Finally, to determine a downtime, all our project has to do is count how many pings fail (have no response) and multiply this by 20 seconds (the time interval between consecutive pings). Although this technique doesn’t result in the exact Internet connection downtime, it does provide a pretty good estimate.Following a downtime event (when the Internet resumes its response), the duration of the downtime event is sent to ThingSpeak. Also, a Tweet is sent to the Internet provider (using a web app from ThingSpeak called ThingTweet). Therefore, two actions are taken as follows:ThingSpeak stores the incoming data and displays it on a chart (in the user’s Thingspeak channel).By means of ThingTweet functionality (a ThingSpeak App) and the user’s Twitter account integration, ThingSpeak will automatically send a tweet to the Internet provider informing them that a downtime occurred and detailing its duration.To sum things up, the way in which this project works is illustrated below:How this project works (Click Here to see a larger image. Source: Pedro Bertoleti) As a plus, all tweeted messages are followed by the hashtag #DownTimeDetected , resulting in a very interesting feature: the more people use this project, the more Internet providers will be monitored regarding their Internet connection quality. So, if you search for this hashtag in Twitter, you’ll automatically see a list of Internet providers that failed to serve good Internet connections. To sum up: you’ll be able to use faithful old Twitter as a tool to check which Internet providers provide good or bad service!First things first: setting-up the Cloud As discussed this projects requires access to a ThingSpeak account and a Twitter account in order to perform its magic. Therefore, these accounts must be established and available before proceeding further with this project.Twitter Account: There’s no mystery here. Just go to the Twitter website at Twitter.com and create an account. It’s as simple as it sounds.ThingSpeak Account: This includes channel creation and ThingSpeak integration with Twitter. In order to do this, please perform the following steps:Go to the ThingSpeak website at ThinkSpeak.comClick on “Sign Up” at the top of the webpage and fill the form to create an accountOnce your account has been created and you’re logged in, click on “My Channel” at the top of the webpage and then click on “My Channels”.You will be redirect to your channel’s administration webpage. Click the “New Channel’ button.Fill in the form to create your ThingSpeak channel. Be sure to enable just one field to the channels.Now it’s time to integrate ThingSpeak and Twitter by means of the ThingSpeak App. Before you proceed, open a new tab in your browser, log into your Twitter account, and keep it logged in.In the ThingSpeak browser tab, click on “Apps” and then on the “ThingSpeak” icon as shown below.In ThingTweet’s webpage, observe the “Example API Endpoint” section. Copy the API Key of this section and save it (or keep in a safe place). This API Key will be required in the project’s code, which we will discuss shortly.Click the “Link Twitter Account” button and follow the instructions to link your Twitter account to ThingTweet.That’s it! Now you’re ready to proceed to the project itself.Talk is cheap, show me the code! It’s code time! Open your favourite text editor (in my case, nano) and enter the following code into the editor (Click Here to access a Notepad/text version of this code):(Click Here to access a Notepad version of this code) Save this as a .py file and, to execute it, just type the following into your CLI (command-ine interface): python NAME_OF_YOUR_SOURCE_CODE_FILE.pyNote: Some Linux distros don’t allow common (non-privileged) users to send pings / ICMP packets. In this case, it will be necessary for you to execute this command as a super-user (using sudo).Nice! But, what’s next? Well, considering the points we’ve already discussed, there are a lot of possibilities we can explore! A few things you can do based on this project are as follows:Configure your Linux distro to execute this program in boot (auto-start). By doing this, you can dedicate a single-board computer to this task and ensure Internet connection monitoring 24 hours a day, 7 days a week, 365 days a year.You can generate some complementary data of your “Internet connection health” and send it to ThingSpeak as well. In fact, I’m sure you’ll want to get more data about your internet connection at some point.A nice hack for a rainy weekend would be as follows: most modern routers support OpenWRT (a very lightweight Linux distro focused on working in network devices, such as routers, IP cameras, and IoT devices). So, if you were to burn OpenWRT firmware into your router, you’ll have a router and a Linux embedded system at your service in the same hardware. This means you could embed this project into your router and let the router automatically monitor its Internet connection.Conclusion This article presented a project to monitor Internet downtime. This project uses very simple network concepts and ThingSpeak Cloud platform functionalities. Also, Tweets regarding downtimes are sent, thereby transforming Twitter into a worldwide database of Internet providers’ quality.

World Cup: Croatia 4 Greece 1

first_imgCroatia 4 Greece 1: Kalinic leads play-off rout in Zagreb Rob Lancaster Last updated 2 years ago 05:55 11/10/17 Luka Modric_cropped Srdjan Stevanovic/Getty Images Greece’s hopes of reaching Russia look bleak after a series of defensive mistakes proved costly in Zagreb. Croatia seized control of their World Cup qualifying play-off against Greece as they claimed a commanding 4-1 home victory in the first leg on Thursday.Despite being without Mario Mandzukic, who was only fit enough for a seat on the bench due to a hamstring strain, the hosts cruised to victory on a cold night in Zagreb, putting them within touching distance of a place at the finals in Russia next year.Having had a hand in the first goal, forcing a foul from goalkeeper Orestis Karnezis to win a penalty that was converted by Luka Modric, Nikola Kalinic steered home a second from close range.

A Liverpool legend in the making: Behind Virgil van Dijk’s remarkable rise to world’s best player Greece briefly responded with a header from Sokratis Papastathopoulos, only to leak a third before the break when Ivan Perisic – left alone at the far post – headed home.Andrej Kramaric’s third goal in his last two international appearances early in the second half extended Croatia’s advantage even further – leaving their opponents with a mountain to climb ahead of the return fixture on Sunday.#WCQ | FTNorthern Ireland 0-1 SwitzerlandCroatia 4-1 Greece:https://t.co/SpQDWJq93q pic.twitter.com/0addSNjGLa— FIFA World Cup (@FIFAWorldCup) November 9, 2017Greece’s issues were all of their own making, with any plan to keep the tie close ahead of the return leg disappearing when they gave away two avoidable goals in the opening 20 minutes.Karnezis’ decision to take a touch with the ball at his feet backfired spectacularly when he presented possession to Kalinic, with the goalkeeper compounding the initial error by carelessly flattening the Croatian forward inside the area.Modric converted from the spot – sending Karnezis the wrong way – and the home fans were soon celebrating again when an unmarked Kalinic converted Ivan Strinic’s low cross from the left wing.Reeling on the ropes after taking Croatia’s one-two on the chin, Greece briefly countered when Sokratis’ looping header from a corner cut the deficit in half.However, having worked so hard to grab an away goal, Michael Skibbe’s side conceded again within five minutes, Sime Vrsaljko’s deep cross from the right presenting Perisic with the simple task of nodding the ball in.The gap would have been greater at the break were it not for Karnezis, who went some way to redeeming his earlier error with a fine double save to deny Kramaric and Kalinic in quick succession.Yet Greece’s calamitous defending was not just confined to the first half.Konstantinos Stafylidis’ attempt to chest a deep cross back to his own goalkeeper served up a fourth goal on a plate, the alert Vrsaljko nipping in to square the ball across for the waiting Kramaric to convert.Sokratis headed over under pressure from Dejan Lovren in a rare moment of concern for Croatia, while Danijel Subasic was required to turn away a 90th-minute header from Konstantinos Mitroglou.Perisic wastefully blazed over when well placed at the other end as Greece narrowly avoided conceding what surely would have been the knockout blow. As it is, they still require a remarkable turnaround in the home leg in Athens. read morelast_img read more

Lletget returns to scene of career-altering injury with USMNT

first_imgSebastian Lletget should be feeling all the positive vibes of enjoying a homecoming this week, but his first match back at Avaya Stadium in almost two years will also bring back painful memories along with plenty of good ones.Having grown up in San Francisco, and played youth soccer in nearby Santa Clara, Lletget knows the area well, and his family and friends will gather at Avaya Stadium on Saturday to watch him play for the U.S. national team against Costa Rica. Some of those same supporters were also in attendance on March 24, 2017, when Lletget scored a goal to help spark the USMNT to a desperately-needed win in World Cup qualifying. It was that same night when Lletget was the victim of a brutal tackle that left him injured, and eventually sidelined for almost a full year.”It’s one of the best moments, and one of the worst in a way,” Lletget said on Friday. “But I’m moving forward from these things and I think I wouldn’t have been so eager to come back if it was something that was going to hurt. It’s a special place, but for sure it has some bad memories.” Article continues below Editors’ Picks ‘There is no creativity’ – Can Solskjaer get Man Utd scoring freely again? ‘Everyone legged it on to the pitch!’ – How Foden went from Man City superfan to future superstar Emery out of jail – for now – as brilliant Pepe papers over Arsenal’s cracks What is Manchester United’s ownership situation and how would Kevin Glazer’s sale of shares affect the club? The LA Galaxy midfielder tried to avoid spending too much time discussing the injury, though he knew from the moment the friendly was announced that he would be facing some familiar emotions upon his return to Avaya Stadium.”I think it will be in the back of his mind, for sure,” USMNT coach Gregg Berhalter said. “When you get injured that (severely) it leaves a lasting impression on your memory. I’ve talked to Sebastian at length about his injury and it’s a tough one. Lisfranc (fracture) is very uncommon in soccer players, but when it happens it’s potentially devastating.”Almost two years later, Lletget has worked his way back into the national team picture, ending a 19-month absence from the USMNT when he came on as a substitute against England in November. He came on as a substitute in the USMNT’s recent 3-0 win against Panama, and Lletget has enjoyed his time under the new U.S. coach.”I feel really good in that system, Lletget said of Berhalter’s preferred playing system. “I can play a couple of positions, but definitely in the midfield is where I belong so I’m really excited.”I think (a number 10 role) is the way forward, especially in this system,” Lletget said. “I think that’s where Gregg likes me and hopefully it works out (on Saturday) too.”Berhalter is still working out where best to deploy Lletget, and Saturday’s match against Costa Rica should a more clear idea of where Lletget will fit the best.”We’re still working on his positioning because we know if we can get him the ball in dangerous positions he can be very effective,” Berhalter said.  I think he’s done a good job of really building his performance throughout the camp.”Lletget will look to close out his latest national team camp with a strong showing against Costa Rica, and is determined to focus on his performance rather than thinking about the ghosts of past painful memories.”Emotionally you have to block that stuff and put up a wall,” Lletget said. “You don’t need to think about that too much because it can mess with your energy. I just want to enjoy being back on the field with the national team.”last_img read more

Deshaun Watson Was Asked If Clemson Is A “Dynasty”

first_imgDeshaun Watson of the Clemson Tigers celebrates with the trophy after defeating the Alabama Crimson Tide to win the 2017 College Football Playoff National Championship Game.TAMPA, FL – JANUARY 09: Deshaun Watson #4 of the Clemson Tigers celebrates with the trophy after defeating the Alabama Crimson Tide to win the 2017 College Football Playoff National Championship Game 35-31 at Raymond James Stadium on January 9, 2017 in Tampa, Florida. (Photo by Streeter Lecka/Getty Images)There is no question that Deshaun Watson enjoyed watching the Clemson Tigers dismantle the Alabama Crimson Tide in the national championship.  Although the superstar quarterback is about to enter his third season in the NFL, it’s clear that he’s still connected to his former team.Watson finished his collegiate career with 10,168 passing yards, 1,934 rushing yards and 116 total touchdowns.The statistics are definitely worthy of praise and recognition, but the most notable moment during his time at Clemson was his title victory over Alabama. In fact, Watson’s game-winning touchdown pass to Hunter Renfrow will go down as one of the most clutch plays in the history of the sport.Clemson has shown its a powerhouse program, making four consecutive trips to the College Football Playoff.Instead of thinking this recent stretch is just a testament to the Tigers’ dynamic quarterbacks in Watson and Trevor Lawrence, it might be time to consider them one of the few dynasties in the country.When asked about whether or not Clemson deserves that label, Watson was very confident in his answer.From 247Sports:The Houston Texans quarterback did exactly that in his latest media appearance. Is Clemson officially a dynasty? “For sure,” Watson told the team Thursday morning on ESPN’s Get Up!“The things that Coach (Dabo) Swinney is bring to that university, the recruits coming in, the things on the field each and every year, it’s one of the top, if not the best, program in the country,” Watson said.With Lawrence leading the Tigers for at least two more seasons, the odds of them adding another title are strong.Alabama was considered the gold standard of college football for almost a decade, but now it might be time to pass the torch to Clemson.Clemson will likely start the 2019 season ranked No. 1 in the country.last_img read more

Misbah-ul-Haq likely to pip Dean Jones for Pakistan head coach job

first_img Next Indo-Asian News Service LahoreAugust 30, 2019UPDATED: August 30, 2019 13:36 IST Former Pakistan captain Misbah-ul-Haq likely to be appointed their head coach (Reuters Photo)HIGHLIGHTSMisbah-ul-Haq favourite for Pakistan head coach jobDean Jones might not be considered as Pakistan not keen on foreign coachWaqar Younis, Courtney Walsh in race for bowling coach roleFormer skippers Misbah-ul-Haq and Waqar Younus appear to be the frontrunners for the head coach and bowling coach posts of the Pakistan national team, respectively .The interviews of candidates for the post of head coach were conducted on Thursday in which Misbah, former Test opener Mohsin Hasan Khan and ex-Australian batsman Dean Jones (through video-link) were interviewed.As per Dawn report, both Mohsin and Dean Jones may not be successful for different reasons. The age factor in 65-year-old Mohsin’s case could go against him while Jones could miss the bus on the ground that he is a foreigner as experiment with foreign coaches has not been good for Pakistan in the past.On Friday, the interviews for the post of bowling coach are likely to be conducted by the five-member panel of the Pakistan Cricket Board (PCB).Waqar, who has earlier served as the Pakistan head coach, also appeared for the post of bowling coach. Mohammad Akram withdrew his name in Waqar’s favour, thus enhancing Waqar’s chances.However, former West Indies great Courtney Walsh, who is likely to appear for the interview through video-link, could prove to be competition for the legendary Pakistan pacer.However, PCB would be wary of the fact that dealing with Waqar has not been easy during the past as he quit the post as head coach twice (in 2011 and 2016) and as bowling coach in 2007 in controversial circumstances.His relationship with the current captain Sarfraz Ahmad was also not an ideal one.The coaching posts of Pakistan cricket team have been lying vacant ever since PCB decided not to extend contracts of Mickey Arthur and others, following dismal performance of the Men in Green in the 2019 World Cup.advertisementAlso Read | Watch: Ravi Shastri attempts to sing Bob Marley’s iconic Buffalo SoldierAlso Read | Ambati Rayudu comes out of retirement, says he has enough cricket left in himAlso See:For sports news, updates, live scores and cricket fixtures, log on to indiatoday.in/sports.

3 Miss America officials resign 1 apologizes to exwinner

first_imgATLANTIC CITY, N.J. – The top leadership of the Miss America Organization, implicated in an email scandal that targeted past pageant winners for abuse based on their appearance, intellect and sex lives, resigned on Saturday, with the outgoing president apologizing to a winner whose weight he ridiculed.The president, Josh Randle, told The Associated Press his comment responding to an email to his private account about the physical appearance of 2013 winner Mallory Hagan came months before he started working for the Miss America Organization in 2015. But he said it was wrong.“I apologize to Mallory for my lapse in judgment,” Randle said on Saturday. “It does not reflect my values or the values I worked to promote at the Miss America Organization. Although this terrible situation was not caused or driven by me, in light of recent events and new developments, I am no longer willing to continue in my capacity as president and earlier today offered my resignation to the MAO Board of Directors.”Randle said his resignation was voluntary and had not been requested by the board of Miss America, which is based in Atlantic City.Hagan did not immediately respond to a message seeking comment on the resignations of Randle, CEO Sam Haskell and Chairman Lynn Weidner. But on her Facebook page, she posted a message asking anyone who was warned away from her to come forward and send her a direct message, in what might be a precursor to legal action against the Miss America Organization or its former officers regarding her post-Miss America work as a pageant interview coach.“If you have ever been told to not work with me, communicate with me, hire me, etc. Will you send me a DM?” she wrote.The scandal began Thursday, when the Huffington Post published leaked emails showing pageant officials ridiculing past Miss Americas, including crass and sometimes vulgar comments about them.The emails included one that used a vulgar term for female genitalia to refer to past Miss America winners, one that wished that a particular former Miss America had died and others that speculated about how many sex partners Hagan has had.Randle noted that the worst communications were exchanged in 2013 and 2014, years before he joined the Miss America Organization, and said the article’s implication of “complicit participation on my part in a years long array of inappropriate email communication” is untrue.Haskell’s resignation is effective immediately, while Randle and Weidner will remain for a few weeks to help with a leadership transition. Dan Meyers, who had been vice chairman of the board, was named interim chairman.The organization announced the resignations a day after dozens of former Miss Americas, including Hagan, signed a petition calling on the group’s leadership to step down because of the emails.The emails already cost the pageant its television production partner and raised questions about the future of the nationally televised broadcast from Atlantic City’s Boardwalk Hall the week after Labor Day each year. Dick Clark Productions told the AP on Thursday that it cut ties with the Miss America Organization over the emails, calling them “appalling.”Also on Saturday, one of the main recipients of fundraising from the Miss America Organization said it was reviewing its association with Miss America. The Children’s Miracle Network Hospitals said it was “conducting an immediate review of the situation and will take appropriate actions.”And New Jersey officials are reviewing their Miss America Organization contract, in which the state still owes $4 million toward the cost of next year’s pageant.___Follow Wayne Parry at http://twitter.com/WayneParryAClast_img read more

Côte dIvoire UN envoy certifies results of first round of presidential poll

Y. J. Choi said the electoral process during the first round held on 31 October was “peaceful and democratic, and that the results of the elections were determined through fair and transparent process.”The “anomalies, irregularities and errors” brought to his attention were “of such minor nature as to affect in no significant way the overall results of the elections,” he added in a statement made in Abidjan. The two candidates in the forthcoming run-off are incumbent President Laurent Gbagbo and former prime minister, Alassane Ouattara.The elections, originally scheduled for as far back as 2005, were repeatedly postponed. They are a major step in restoring stability in the country, which was split by civil war into a Government-held south and rebel Forces Nouvelles-controlled north in 2002.An additional 500 troops were sent to the country to reinforce the 8,650-strong UN peacekeeping force (UNOCI) and assist with security during the election period.Mr. Choi, the Secretary-General’s Special Representative for Côte d’Ivoire and head of UNOCI, noted that polling day during the first round was “marked as much by enthusiasm of the population as by the respect for human rights and democratic principles.” He called on all stakeholders to remain committed to the holding of an open, free, fair and transparent second round of the presidential elections, in order to bring the Ivorian crisis closer to a conclusion.Cote 12 November 2010The United Nations envoy to Côte d’Ivoire today certified the results of the first round of the presidential election in the West African country, paving the way for the run-off on 28 November between the two candidates who garnered the highest number of votes. read more

Rogers to open lab in Waterloo Region to develop commercial uses for

WATERLOO, Ont. — Rogers Communications Inc. says it will open a new innovation lab in Waterloo, Ont., in September to advance the commercialization of fifth-generation wireless networks that will begin to roll out next year.The initiative includes a three-year partnership with Communitech, which promotes and supports Waterloo Region as a community for innovative startups and larger technology players.Rogers says its Waterloo lab will complement other 5G research work it has been doing at the University of British Columbia.The Toronto-based company, which owns one of Canada’s three national wireless networks as well as cable television, internet and media businesses, has also been working with Swedish 5G network vendor Ericsson.5G wireless networks are expected to carry vastly more data traffic than current 4G networks, opening up a wider array of uses for collecting and transmitting information through connected devices.Rogers says the Waterloo 5G innovation lab will help it bridge the gap between the conceptual potential of the technology and commercialization.

Competition in Big Ten womens volleyball difficult

The Ohio State women’s volleyball team celebrates a victory against Michigan Sept. 27 at St. John Arena. OSU won, 3-1.Credit: Mark Batke / Lantern photographerWhen it comes to women’s volleyball, the Big Ten rules the rankings.As of Monday, seven of the conference’s 12 teams are ranked in the American Volleyball Coaches Association Top 25 Poll, with three others in the conference receiving multiple votes. That means 10 of 12, or more than 83 percent of all Big Ten women’s volleyball teams are either ranked or close to it. The conference with the second-highest number of teams either ranked or receiving votes is the Pac-12, with seven.Currently leading the pack is No. 2 Penn State, while Minnesota, Nebraska, Michigan State and Wisconsin all sit in the top 15. Purdue and Michigan come in at 16th and 17th, respectively, and Ohio State, Illinois and Northwestern each received votes.Northwestern coach Keylor Chan, who has led the Wildcats to a 5-5 conference record, said rankings are thrown out the window when it comes to Big Ten play.“It’s just difficult,” he said. “Every weekend you have great teams coming in, you never have a break.”Chan added that his team prepares for each opponent the same, no matter its national standing.“We prepare for everyone,” he said. “You’re preparing for each team, I don’t think rankings tell you what a team is like.”Chan’s Wildcats have not yet been ranked this season, but they have topped multiple teams featured in the AVCA poll. Northwestern beat then-No. 20 Purdue Oct. 12 and on Oct. 16, the Wildcats beat then-No. 17 Ohio State. The Buckeyes, who have been ranked as high as No. 12 this season, currently sit outside of the top 25 after finding out just how tough the competition is.OSU is currently 2-8 in Big Ten play, which includes six consecutive losses. The Buckeyes opened their conference season with a 3-1 home victory over then-No. 10 Michigan Sept. 27, but have not topped a ranked opponent since then.Even taking into account the team’s recent struggles, OSU still received 43 votes in the most recent AVCA poll.So Buckeyes have already played seven matches against current teams in the top 25. They are scheduled to play six of their final 10 Big Ten matches against currently ranked opponents.Freshman defensive specialist Valeria León said the competition is high in the Big Ten and that she and her teammates always have to be on top of their game.“You know, Wisconsin can beat Nebraska and Nebraska can beat Penn State,” León said. “You never know, we have to play hard every game.”Despite a tough schedule, OSU coach Geoff Carlston said he is “proud to be part of the Big Ten.”“It’s fun to figure out the problems and try to figure out what we need to do,” he said.Freshman middle blocker Taylor Sandbothe said playing in such a tough conference creates stronger players.“Honestly, playing in the Big Ten, it’s the best volleyball conference,” she said. “I think you’re going to be the best player you can be by coming out of it.”Four members of the 14 players named to the 2012 AVCA Division I First-Team All-America squad came from Big Ten schools. Six players from the conference made the second-team, four made the third-team, including Mari Hole from OSU, and four more made the honorable mention list.Senior outside hitter Kaitlyn Leary said the level of play is never a burden.“I love playing in the Big Ten, it’s one of the reasons I chose Ohio State,” she said. “Every single game you’re playing a top 20 team. It’s awesome, it’s fun and it definitely prepares you for the tournament.”Carlston, his players and Chan all said they agreed that winning a Big Ten title is tougher than winning a national championship.“(To) win the Big Ten title, you have to be good for 10 weeks,” Chan said.As is often the case, the Buckeyes are scheduled to return to the court this weekend for two more ranked matches.OSU is set to travel to East Lansing, Mich., Friday for a match against No. 14 Michigan State, before heading to Ann Arbor, Mich., Saturday for a date with No. 17 Michigan. read more

Almost all cannabis on Britains streets super strength and could be driving

first_imgNearly all cannabis on Britain’s streets is now super-strength skunk that could be fuelling the rise in mental health problems, scientists have warned.Researchers at King’s College London tested almost 1,000 police seizures from Kent, Derbyshire, Merseyside, Sussex and the capital in 2016 and found 94 per cent were of a dangerously high potency.In 2005 just 51 per cent of cannabis sold on the street was sinsemilla, also known as skunk.Dr Marta Di Forti, Medical Research Council Clinician Scientist at King’s College warned that the powerful drug placed Britain’s 2.1 million cannabis users at risk of schizophrenia, bipolar disorder, depression, psychosis, delusions and hallucinations.‘The increase of high-potency cannabis on the streets poses a significant hazard to users’ mental health, and reduces their ability to choose more benign types,’ she said.“It is of  concern that 94 per cent of seized cannabis is now of skunk type as this potentially could increase the number of people using it and consequently the number of people experiencing harm.“Regular users of high-potency cannabis carry the highest risk for psychotic disorders, compared to those who have never used cannabis.” A selection of skunk seized by British police forces in 2016  In contrast, the ratio of antipsychotic cannabidiol (CBD), which helps mitigate the drug’s psychoactive effects, had fallen dramatically.Skunk has around 14 per cent THC and is more dangerous because it contains very small amount of CBD.In 2015 Kings College showed that in South London, 24 per cent of new cases of psychosis could be attributed to skunk use. Researchers now fear that the countrywide problem could be partly responsible for the growing number of mental health issues in Britain.Latest figures shows there were 7,545 hospital admissions in 2016/2017 for drug-related mental health and behavioural disorders, 12 per cent higher than in 2006/2007.There were also 14,053 admissions for poisoning by illegal drugs last year, a 40 per cent increase compared to a decade earlier. The researchers also found that in normal cannabis resin, the average concentration of tetrahydrocannabinol (THC) – the main psychoactive component – had risen by 50 per cent since 2005, from four per cent to six per cent.

Toshiba to make Lytrostyle camera for smartphones

first_imgSince the release of the incredibly cool Lytro camera, the big question has been when we will see this kind of technology in our existing mobile devices. According to Toshiba, we need only wait until the end of 2013 to see this tech in smartphones and tablets.The way we take photos with smartphones, it stands to reason that most of us could benefit from a camera that allowed us to adjust focus after the image was captured. That’s the power of the Lytro camera, being able to shift focus even after the photo has been taken. Some have even used this to create images that reveal more when you shift focus, placing some items out of view intentionally for fun. Lytro cameras, however, are roughly the size of a can of Red Bull. It can’t be easy to shrink that experience down and maintain even close to the same quality. Toshiba seems convinced that they can fit the technology into a 1cm cube to replace the rear camera on smartphones being released late next year.It’s difficult to imagine 500,000 lenses in a 1cm space, but that is exactly what Toshiba claims will happen with their camera. The camera will be able to measure the distance between you and the objects in the shot, and allow you to apply focus after the shot has been taken between those objects. Toshiba says that the sensor for this camera is still a work in progress, so we have no idea what the quality of the image will be. A lower quality sensor will mean a lesser quality image to adjust focus in, which may ruin the feature altogether. Over the last year there have been tremendous strides in the quality of smartphone cameras and the software that drives it, and moving backwards in either of those places for the sake of a new feature will not go over well with consumers.There’s also the thickness of the phone to consider. Much like the massive bulge on the back of the Nokia PureView, the camera unit Toshiba is proposing is in and of itself nearly 2.5mm thicker than the current generation iPhone. After you wrap that lens in plastic and stick it on the other side of a smartphone, you wind up with a phone that will be noticeably thicker than most current generation smartphones.If smartphone manufacturers pick up the technology from Toshiba, we’ll see a return to the camera bulge that had finally gone away in the second half of 2012, but we’ll also see some very impressive images.Asahi via Engadgetlast_img read more

La France restitue à la NouvelleZélande une tête maorie

first_imgLa France restitue à la Nouvelle-Zélande une tête maorieLe lundi, la ville de Rouen a reçu l’ambassadeur de Nouvelle-Zélande afin de lui remettre lors d’une cérémonie une tête maorie momifiée. Une pièce de collection que leMuséum d’Histoire Naturelle de la ville conservait depuis 1875.Alors que quinze autres têtes maories sont conservées dans diverses villes françaises, Rouen est la première à avoir rendu à la Nouvelle-Zélande celle qu’elle possédait. Cette restitution a eu lieu lundi à l’Hôtel de Ville de Rouen, en présence de l’ambassadeur de Nouvelle-Zélande et de représentants de familles maories, rapporte le site de France 3 Haute-Normandie. Cette tête momifiée était conservée depuis 136 ans par le Muséum d’Histoire Naturelle de Rouen.À lire aussiUne momie égyptienne vieille de 5500 ans renverse nos croyances sur l’embaumementLa Nouvelle-Zélande procédera à une expertise afin de déterminer les origines familiales de la tête, puis de l’inhumer selon les rites maories. Déjà, lundi, des chants et incantations ont accompagné la restitution de la pièce, avant que les familles maories présentes à la cérémonie ne remercient les élus de la ville en les saluant selon la tradition, nez à nez. Si cette tête est la première rendue par la France à la Nouvelle-Zélande, deux autres ont déjà été restituées, le 5 mai, par la Faculté de Médecine d’Oslo et un musée norvégien. Voilà trente ans que la Nouvelle-Zélande tente de récupérer ses têtes, emportées au fil des siècles par les colons européens. L’année dernière, après plusieurs années de refus, la France a adopté une loi autorisant le retour dans leur pays, de la quinzaine de têtes momifiées qu’elle détient.Le 10 mai 2011 à 10:04 • Emmanuel Perrinlast_img read more

NASA la mission TESS partira à la recherche dexoplanètes dès 2017

first_imgNASA : la mission TESS partira à la recherche d’exoplanètes dès 2017La NASA vient de sélectionner un projet du Massachusetts Institute of Technology (MIT) pour lancer un satellite permettant de récolter des informations sur des exoplanètes. Après trois ans de compétition, la NASA vient de choisir le Transiting Exoplanet Survey Satellite, alias TESS, un projet du Massachusetts Institute of Technology (MIT) qui devrait être lancé en 2017. L’agence spatiale a annoncé que le projet serait financé par une subvention de 200 millions de dollars accordée à l’équipe de TESS par la NASA elle-même.Mené par George Ricker, chercheur au MIT Kavli Institute for Astrophysics and Space Research (MKI), le projet utilisera de nombreuses caméras grand angle afin de capturer une vue d’ensemble du ciel la plus large possible. L’objectif ? Découvrir des exoplanètes en transition près du système solaire, dont la taille irait de la Terre aux géantes gazeuses, précise le MIT.”TESS sera la première étude d’origine spatiale permettant d’analyser les objets en transit dans le ciel, en couvrant 400 fois plus de terrain que les missions précédentes. Nous serons capables d’identifier des centaines de nouvelles planètes situées dans le voisinage du système solaire, en nous focalisant particulièrement sur des planètes dont la taille est comparable à celle de la Terre” explique George Ricker.De nouvelles innovations pour TESSLe satellite permettra d’étudier la masse, la taille, la densité, l’orbite et l’atmosphère d’une multitude de petites planètes, y compris les nuages de rochers. Il sélectionnera un ensemble de cibles intéressantes dont les données seront transmises notamment au James Webb Space Telescope. Des études précédentes, réalisées à l’aide de télescopes basés sur Terre, avaient déjà permis de découvrir des exoplanètes géantes. De même, le télescope spatial Kepler de la NASA a récemment découvert des exoplanètes plus petites, mais ces dernières sont difficiles à étudier. TESS devrait lui permettre d’examiner un grand nombre de petites planètes, situées autour des étoiles les plus brillantes du ciel. “Nous avons pu déterminer un nouvel orbite “Goldilocks”, ni trop éloigné, ni trop loin de la Terre et de la Lune pour TESS”, précise M. Ricker. Ainsi, environ toutes les deux semaines, le satellite sera assez proche de la Terre pour envoyer ses données, tout en restant à l’abri des radiations, gardant les caméras à une température stable. Le projet TESS prévu pour 2017 sera réalisé en partenariat avec l’Instituts for Astrophysics and Space Research du MIT Kavli, le Lincoln Laboratory du MIT, le Goddard Spaceflight Center de la NASA, l’Orbital Sciences Corporation, le Ames Research Center de la NASA, le Harvard-Smithsonian Center for Astrophysics, l’Aerospace Corporation et le Space Telescope Science Institute. Outre George Ricker, l’équipe sera composée de Josh Winn, professeur de physique au MIT et Sara Seager, professeur en sciences et physique planétaire au MIT. “La sélection de TESS par la NASA a accéléré nos chances de découvrir des formes de vie sur une autre planète dans les prochaines décennies”, s’enthousiasme Sara Seager.Le projet NICERÀ lire aussiDes chercheurs auraient découvert l’origine de la mystérieuse lumière verte observée par la NASAMais la NASA a également sélectionné un autre projet baptisé NICER pour Neutron Star Interior Composition Explorer. Celui-ci consiste à équiper la Station Spatiale Internationale (ISS) d’un instrument pour observer les rayons X des étoiles. Ce dernier permettra de mesurer la source des rayons X cosmiques, grâce à un procédé, appelé X-ray timing, explique la NASA. L’objectif est d’explorer les différents états de la matière à l’intérieur des étoiles à neutrons afin de révéler leurs compositions intérieure et extérieure. NICER sera dirigé par Keith Gendreau du Goddard Space Flight Center de la NASA, grâce à une subvention de 55 millions de dollars. La NASA a déjà financé plus de 90 missions. La première, Explorer 1, a été sélectionnée en 1958. Elle a permis de découvrir les anneaux de radiation de la Terre.(Crédits photo : MIT Kavli Institute / Nasa / TESS Team) Le 8 avril 2013 à 18:20 • Emmanuel Perrinlast_img read more

Teen in need of kidney transplant keeps eyes on prize

first_imgThe prize has been waiting for Jade Samples since Halloween.Hidden on the top shelf in the back of Samples’ freezer is a bag of milk chocolate M&M’s. Samples, a 17-year-old Vancouver resident, won the candy for her costume at a church youth group function in October. She dressed up as Edward Scissorhands, and made the claws herself with duct tape and black gloves.Samples didn’t finish first for best costume, but she nabbed second place — and the winner happened to already have left the costume party. Samples won the chocolate by default. She’s OK with that.But Samples has to wait on the M&M’s because she’s experiencing kidney failure and is in need of a lifesaving kidney transplant. In May 2017, Samples was diagnosed with Lupus, a disease that causes the body to attack its organs. She has been undergoing dialysis treatment three days a week, waking up before 6 a.m. to make it to her 3 1/2 -hour appointments in Portland.“This is a new thing. I’m not ready for new things yet” is how Samples remembers reacting to her diagnosis. “I’m one of those people, if I can stay in one spot as much as possible, I’m OK. So a lot of different new things isn’t my cup of tea.”She also has plenty of diet restrictions, which have robbed her of a favorite food (mashed potatoes), and prohibits two other favorites: dairy and chocolate.last_img read more
