Ebola Claims another Victim

first_imgThe Ministry of Health and Social Welfare (MoH&SW) has disclosed that the remaining sister who provided one of the two blood samples that were tested positive out of seven sent to Lyon, France for laboratory testing, has died.On Sunday, March 30, Health and Social Welfare Minister, Dr. (MD) Walter Traub Gwenigale told the Daily Observer the Ebola virus was in the country and had claimed a life, which was the sister of the lady, who passed late Wednesday evening.“On April 3, the second lady whose case was confirmed died at Firestone; bringing the death toll to seven. This includes the two [Ebola] confirmed cases and five probable cases. Since March 24, 14 suspected cases of the Ebola Virus Disease have been reported, pending laboratory confirmation,” the Health Ministry said in its daily updates on the situation. The lady, who died in Harbel, Firestone, might have contracted the virus from her sister, who she (the Firestone deceased) looked after when she was sick.The World Health Organization (WHO) indicates that the virus has a case fatality rate of 90 percent: meaning that out of every 10 persons, who contract the virus, nine die.Providing an update at the Ministry of Information, Culture Affairs and Tourism (MICAT) regular Thursday press briefing, Health Minister Gwenigale said the other lady (name not mentioned) had succumbed to the Ebola virus.The latest victim, according to the Health Ministry’s authorities, reportedly traveled from Foya in Lofa County to Chicken Soup Factory in Monrovia and then to Harbel in Firestone before she was quarantined. They disclosed that the deceased travelled with her daughter, who it is now assumed contracted the virus from her mother after coming down with its symptoms.According to Minister Gwenigale, his worries are now centered on the surviving daughter (identity withheld) and others the deceased might have possibly come in contact with while traveling from Lofa to Monrovia and then to Firestone.This opens a possibility that some of the people she interacted with on her way and since her arrival in Firestone have also become infected.The health boss indicated that casualties of suspected Ebola cases in the country have now reached seven, including another woman who was quarantined in Foya, but was taken away by relatives to an unidentified pastor for delivery prayers.He said another 25-year-old young man, who was suspected of contracting the virus has also died in Tappita, Nimba County, though he said that health practitioners are still investigating his death to ascertain the truth as to if it is Ebola related.“Also under investigation is the death of a Bassa man in Grand Gedeh, who was suspected of having the virus. We have to take this thing very seriously. It saddens me that people are saying that we are only looking for money to enrich ourselves,” he lamented.Minister Gwenigale also disclosed at the press conference that experts have begun to arrive in the country to help his team battle the deadly Ebola virus.He said two medical experts from medical organization Medicin San Frontier (MSF) arrived in the country Wednesday, April 2, to help his team battle the virus.“They will be helping medical practitioners prevent themselves from contracting the virus while at the same time attending to patients,” Min. Gwenigale said.Meanwhile, Dr. Gwenigale disclosed that the Health Ministry has received US$250,000 from the Ministry of Finance to begin the exercise of containing the virus.The Ministry has budgeted US$1.2 million for its fight against the virus; but to date only US$300,000 from the GOL plus a US$10,000 from the Mano River Union Secretariat in Monrovia, has come in so far.Dr. Gwenigale again urged everyone within Liberia’s borders to adhere to these preventive actions such as do not eat animals that are found dead in the bush, and avoid contacts with fruit bats, monkeys, chimpanzees, antelopes and porcupines. Limit as much as possible, direct contact with body fluids of infected persons or dead persons. Wash your hands with soap and water as frequently as possible. Treat your water with chlorine before drinking. The Ministry’s hotline numbers including 0770198517, 0777549805, 0886530260 and 0886549805 are still active for people to call and report any suspected Ebola case(s).Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)last_img read more

Generous Jennie still making her ‘presents’ felt at 90!

first_imgTwo of Donegal’s favourite charities received a timely boost this week thanks to a wonderful donation from generous Raphoe woman Jennie McCarron who celebrated her 90th birthday recently.The St. Eunan’s Terrace resident Jennie (nee Devenney) was born on 14th August 1927 and was delighted to have celebrated her 90th birthday in Friels of Raphoe, surrounded by family and friends.But when Jennie asked for no presents, her guests kindly donated €1617.40 that she decided would immediately be donated to charity. The two local charities to benefit from Jennie’s wonder generosity are Pieta House and the Donegal Hospice.Some of Jennie’s great-grandchildren gathered during the week to hand over cheques for €808.70 to the well-loved charities, while Jennie’s family once again extended their sincere thanks to everyone who donated.Great grandchildren of Jennie McCarron from Raphoe pictured presenting a cheque for €808.70 to Joan Kane and Dominck Gallagher of Pieta House. The money was raised through donations made at Jennie’s recent 90th birthday party.Generous Jennie still making her ‘presents’ felt at 90! was last modified: August 23rd, 2017 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:90th birthdaycharitydonegalJennie McCarronRaphoelast_img read more

More Fakes in the Science Laboratory

first_imgFake news is not just a problem in politics.by Dr Jerry BergmanThe problem of fake research in science has long been recognized as serious threat to science, especially in the field of evolution. (See the new book by Jerry Bergman Darwinism’s Frauds, Blunders and Forgeries. Atlanta, GA: CMI Publishing. 2017). A new study has now even found evidence of fake reagents, chemicals central to much science research! The review, titled “The Secret War Against Counterfeit Science” was published in Nature (545:148-149; May 15, 2017). The story begins:In 2013, Huang Song walked into a printing shop in northwestern Beijing and stumbled upon evidence of a brazen and widespread criminal enterprise. Huang was just 15 kilometers from Beijing’s National Institute of Biological Sciences, where he does synthetic-biology research. Scouting out a small desktop machine to produce the hundreds of labels needed for his experiments, he asked if a certain model could print on heat-resistant paper. The shop owner proudly pulled out some samples he had made for customers using the same machine.These labels looked exactly like those found on expensive antibodies and reagents produced by the leading Western Labs, including Abcam and Cell Signaling Technology. They were produced in order to fool buyers into thinking that the products they were purchasing were the pure quality product. For Professor Huang, it directly corroborated what he and his colleagues had long suspected: many of the antibodies sold by Chinese distributors were counterfeits. As a result, the diluted research reagents, or even outright fakes, were on the world market. This means an untold number of medical and biological research results were suspect. The problem could also undermine China’s efforts to become a world leader in science research.The only way to find out what studies have been compromised is to replicate many thousands of past research studies, something that will never happen.Antibodies are proteins produced by the body in response to encountering a specific antigen, such as bacteria, viruses, and toxins. Antibodies can also be produced by various artificial means, such as when antibodies specific to a pathogen or toxin obtained from humans, horses, or other animals are transferred to non-immune persons. Antibodies chemically combine with things that the body recognizes as a problem to destroy or neutralize them.An example of what can happen when inferior antibodies are used is, six months after publishing a paper, one scientist discovered that he could not repeat the results of his experiments. After reviewing the normal trouble shooting problems, he discovered that a reagent used to introduce DNA into cells was likely counterfeit. The only way to find out what studies have been compromised is to replicate many thousands of past research studies, something that will never happen. How many other similar examples have occurred will likely be forever unknown, partly due to the reason that much research is not replicated because the rewards in science are for new discoveries, not for repeating some other scientists’ research. This problem just adds to the already well documented problem of research results that were deliberately faked in order to prove some theory or result to obtain research grants or other rewards.(Visited 635 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

South Africa sets off on Transport Month

first_img30 September 2015Under the theme “Together we move South Africa forward”, the Department of Transport will launch its annual October Transport Month (OTM) campaign on 1 October.OTM focuses on infrastructure projects that have major socio-economic spin-offs, for all modes of transport such as road, aviation, maritime, rail and public transport.Focus areasThis year, emphasis will be placed on four pillars:Jobs created through infrastructure and other service delivery programmes;Major infrastructure developments and improvements and links to local economic developments;Special programmes aimed at youth and women; and,Rallying all sectors of society to improve road safety with an opportunity to market programmes to be implemented by the Road Safety Advisory Council.Ongoing transport projectsKey projects will include the official opening of road infrastructure projects, such as the R71 Moria Project (interchange safety improvement), Umgeni Interchange and Denneysville Sasolburg Road in Free State.Minister Jeff Radebe, the minister in the Presidency responsible for planning, monitoring and evaluation, said OTM was also an opportunity to increase road safety awareness. In addition, traffic officers will rotate work shifts for a 24-hour day to help decrease the number of road accidents.“(The) government has also developed a qualification for traffic officers from National Qualifications Framework (NQF) 4 to NQF 6 in order to further professionalise the traffic fraternity,” he said.EcomobilityGauteng’s business hub, Sandton, will take part in the Ecomobility World Festival during OTM. The aim is for a car-free CBD for the duration of the festival.“We want to close off certain streets in Sandton, our second largest CBD, to car traffic and instead use these lanes for public transport, walking, cycling and other forms of ecomobility during the entire Transport Month,” said Johannesburg Executive Mayor Parks Tau.“We want to show residents and visitors that an ecomobile future is possible and that public transport, walking and cycling can be accessible, safe, attractive and cool!”The city is providing alternative modes of transport to Sandton.@Sandton_News@CityofJoburgZA I think #joburgecomobility is a fantastic initiative; it’s definately the direction we need to move in.— David Klompas (@dave_klompas)September 29, 2015Looking forward to #JoburgEcoMobility month, ready to cycle to work off the Gautrain bus. Sandton should be interesting.— mzo ntuli (@mzolisto_n) September 28, 2015For more information, visit the Ecomobility World Festival website.Cape Town suburb goes car-freeIn Cape Town, Open Streets Bellville takes place on 4 October, when Kruskal Avenue and part of the very busy Voortrekker Road become a car-free corridor for residents to explore, use and play on their streets.“October is Transport Month,” explains Marcela Guerrero Casas, Open Streets Cape Town co-founder and director, “and everyone is encouraged to use public transport. In addition to trains and minibus taxis, there are already 140 cyclists confirmed to be riding from the centre of Cape Town to the Bellville CBD along Voortrekker Road.Watch Open Streets Cape Town take over the city’s Bree Street:In addition to promoting alternative modes of transport, the programme – which is supported by the city of Cape Town – aims to help connect different communities, support local businesses and expose people to healthy and creative ways of using streets as public space for recreation.Activities on the day will include local performers and artists, a reading corner, street soccer, skateboarding and children’s games. The Cape Cobras cricket team will also be launching their season with an appearance on the day, to play street cricket with children as part of their community development activities.Open Streets Cape Town is a citizen-driven initiative, working to change how streets are used, perceived and experienced. It was founded in 2012. Open Streets is a 40-year-old global movement inspired by Bogota’s Ciclovia.Watch what happens when Open Streets Cape Town gets going:Source: SAnews.gov and SAinfo reporterlast_img read more

Govt slams Team Anna, says Lokpal draft will be ready by June 30

first_imgThe logjam over Lokpal bill continues. Soon after Team Anna criticised it over lack of transparency, the government on Thursday lashed out at the civil society members over the anti-corruption ombudsman, saying “they want to run a parallel government”. The government also said it will be ready with the Lokpal draft by June 30.  A day after the joint Lokpal panel meeting ended in a deadlock, anti-corruption crusader Anna Hazare had said the government had no intention to fight the graft and that he would start another satyagrah on August 16. Team Anna has said there are no discussions at the meetings and the government is simply trying to push its version through. “We are analysing their views in the context of the framework of the Constitution,” Human Resource Development Minister Kapil Sibal shot back.  “We have agreements on many issues, but there is a divergence of views about the structure of the Lokpal bill. They want to create an independent Lokpal. We asked ‘where will you find the manpower?’ Can there be a change of heart among the same people who will work under you?” asks Sibal, flanked by Home Minister P. Chidambaram and Salman Khursheed, Minister of Water Resources and Minister of Minority Affairs. “Why do you want audio/video recordings – to flash it on TV channels, to castigate ministers? This is a very serious business (drafting of the bill),” Sibal asked, referring to RTI activist Arvind Kejriwal’s remarks a while ago that the government was not sharing the clippings. Chidambaram said the political process must be respected and promised that the government would complete the Lokpal draft by June 30.  “There is big gap between what is desirable and what is feasible. We must respect the laws of Parliament. We must respect the political process,” he said. Earlier, Anna, who announced to go ahead with his fast from August 16, had castigated the government over lack of any discussions at the meetings and the government’s two-draft theory.  “What is the point of a joint panel, if there are two drafts,” Hazare, who was flanked by other civil society members, including RTI activist Arvind Kejriwal and lawyer Prashant Bhushan, said on Thursday. “I was surprised by the government stand on the Lokpal bill,” said Hazare, who has threatened to go on a hunger strike again accusing the government of being uninterested in a strong bill. Referring to the government announcements on two drafts in case of disagreements, Hazare had stated earlier that he was not optimistic about expecting anything from the government anymore. Hazare had led a mass indefinite hunger strike at Delhi’s Jantar Mantar in April.  Kejriwal said the government has refused to listen to the arguments of the civil society members, saying even 20% of the basic issues were not discussed at the meetings. Calling the Lokpal meetings a farce, Kejriwal said if the Lokpal bill was introduced in Parliament without civil society’s grievances beings addressed, it would be ‘a jokepal bill’. He said the government has also refused to give any promise on sharing the audio recordings of the meetings. Meanwhile, Law Minister Veerappa Moily said, “I am the convenor of the Lokpal drafting committee. We are keen to bring the bill. It is our genuine intention to bring the bill in Parliament in the monsoon session. But we observe that after every meeting is over, the civil society members go to public attacking us. This is not right.”advertisement- With inputs from Headlines Today For more news on India, click here.For more news on Business, click here.For more news on Movies, click here.For more news on Sports, click here.last_img read more

John takes over as High Performance Director of Indian hockey

first_imgNew Delhi, Nov 29 (PTI) Former exercise physiologist of the senior national mens team David John of Australia was today officially appointed as the High Performance Director of Indian hockey. John, whose appointment was officially confirmed by Hockey India today, will take over the charge of High Performance Director from Roelant Oltmans, who has been relieved from the post after being named as the chief coach of the Indian mens hockey team till 2020 Tokyo Olympics. John has previously worked with the senior national mens team as an exercise physiologist and scientific advisor prior to 2012 London Olympics. In his previous role, John had implemented and introduced new strength and training programs for the Indian men hockey team, which is responsible behind the much-improved fitness of the national players. John has also worked in a similar role — as a High Performance Director — for two teams in the Hockey India League, most recently for Kalinga Lancers in the 2016 season where the team finished runners up. John has vast experience across various sporting disciplines, which includes hockey, rugby, Australian Rules Football and triathlons. Speaking about Johns appointment, Hockey India secretary general Mohd Mushtaque Ahmad said: “We welcome Davids (John) inclusion into a role that has over the years become one of great importance for Hockey India. A High Performance Directors role is one that is not just demanding in the present but also has to include a vision for the future. “We are confident with Davids extensive experience and background in sports science, out athletes will have the best planning and assistance ahead of the 2020 Olympic Games.” John himself said he was looking forward to his new demanding job. “The role comes with its own unique set of challenges. I am hopeful that my previous experience as well as presence of people who share a deep and long history with the game in the country will help me fulfil my role,” he said. “One of the crucial areas is the identification and nurturing of talent in the country and look to develop the team for the 2020 Games. I look forward to working towards that,” John added. PTI SSC SSCadvertisementlast_img read more

Chennai, Minerva get direct entry into I-League

first_imgChennai City FC and Chandigarh-based Minerva Academy FC were on Sunday handed direct entries into the I-League, sources at the All India Football Federation’s (AIFF) bid evaluation committee meeting said.Minerva Academy had finished behind Dempo in the I-League second division in 2016. They have since then renamed themselves as Minerva Punjab FC.Chennai City FC, on the other hand, play in the local league in Chennai. AIFF has also incorporated Goa’s Churchill Brothers to play in the I-League, making it a 10-team contest.The 2016-17 edition of the tournament is scheduled to start in January next year.Chennai City FC, it was learnt, had submitted a bid for direct entry in the league but failed to meet the financial criteria which needed a performance bank guarantee of Rs 100 crore.But they were given the nod after AIFF watered down the bank guarantee to a mere Rs 1 crore.Popular Goan club trio of Salgaocar, Sporting Clube de Goa and Dempo SC recently pulled out of the I-League citing AIFF’s lack of vision.The withdrawls left AIFF with barely seven teams in the I-League top division, which included the relegated Aizawl FC and Churchill, who are being recalled after a two-year hiatus.Churchill were denied permission to play in the top division for failing to follow strict Asian Football Confederation (AFC) guidelines.They were part of the I-League till 2014 but were dumped for failing to fulfil the mandatory club licensing criteria.Since then, Churchill filed four petitions in the Delhi High Court and earned a relief last week when the court asked AIFF to consider their application.advertisementGoa’s FC Bardez and Neroca FC from the North East region of the country also submitted their bids but failed to make the cut.last_img read more

Why DSPs are suddenly everywhere

first_imgWhen ARM CPU cores were first validated though adoption by some of the premier names in computing including Apple, usage exploded especially for mobile applications. In retrospect the advantage was obvious – any device could be made much more flexible and feature-rich with an embedded processor. At the same time, that capability could be upgraded in software: A single hardware platform could drive multiple product releases through software-only upgrades.(Source: CEVA)These compute engines are very flexible and are perfect for many of the management and general-purpose compute tasks in our smartphones and other mobile products, but that generality comes with a drawback. There are certain operations which on a general-purpose computer would run far too slowly and consume far too much power to be practical. The modem in the wireless communication part of your smartphone was an early example. This has to process radio signals in real-time, dealing in each case not with the familiar digital words and bits used inside the computing part of the phone, but rather with a digitized version of the continuously varying analog signals used in radio transmission and reception.Digital signal processors (DSPs) are designed for this kind of analysis. They have the built-in floating-point representation needed for digitized signals and they have strong support for the math functions needed in signal processing, such as multiple-accumulate (MAC) functions. They’re also optimized to process streaming data, rather than the more batch-oriented processing common in conventional compute, an essential feature in this case for handling continuous radio transmission and reception.Audio processing needs share many of the same features seen in wireless signal processing. This application of DSPs became common in high-end audio applications such as equalization and range compression (for example Dolby compression), then increasingly in functions like the noise cancelling headphones which allow you to sleep undisturbed during your flight.Then AI took off, initially only in datacenters but now more and more in mobile and other edge applications. Our cars can now detect pedestrians and potential collisions, and they can detect lane markings to guide steering in a basic form of self-driving. We can control our TVs or our smart speakers through voice commands, to find a song or a movie or lower or raise volume. We can even control the GoPro on our bike safety helmet through voice commands to start or stop taking pictures.All of these capabilities depend on processing streaming data (voice) or images (camera still images) or possibly both (video), each in real-time or very close to real-time. Look first at audio processing. First you need to capture a high-quality streaming audio signal – through audio beamforming from multiple microphones, echo cancellation and noise suppression – all areas where there are already years of experience in DSP implementations.Then you must recognize commands using a trained neural network, the basis of almost all of these AI techniques. These algorithms look very different from those you would run on a CPU; and while they can run on a CPU, they would be slow and run down the battery quickly. A better approach is to program the neural net on an architecture which offers a high level of parallelism, allowing many computations to run at the same time rather than serially as on a CPU. This is another core strength of a DSP – parallelism in computation.You might wonder if, despite all these advantages, DSPs may be simply too complex to use to be adopted by anyone other than the specialists who have no choice but to use them. Certainly they’re not quite as simple to use as CPUs but the differences are not so big. You write C-code for both, though you need to be a little more thoughtful in the code you write for a DSP to get full advantage of performance.(Source: CEVA)As for widespread adoption, every radio on your phone – Bluetooth, Wi-Fi and cellular – uses one or more DSPs. Bluetooth earbuds use DSPs, for the Bluetooth and also the audio. Many smart speakers use a DSPs. Voice controlled remotes use DSPs. Home security systems use DSPs to detect anomalous movement on cameras and unusual sounds such as a dog barking or breaking glass. Smart sensors in your car use DSPs to detect forward and backup hazards and to detect lane markings.Why not use GPUs for all these functions? GPUs are indeed very well-known especially for AI and have been widely used in data centers for neural net training. But they’re too big, too power hungry and too expensive for many edge applications. There’s a big push to move more AI functions to these devices for reasons of power, security and privacy. But these have to be very cost-effective solutions. In most cases there’s little appetite to add significantly to the cost of the total solution (car, TV, home security).Which is why embedded DSPs are getting everywhere. You can add voice control, object detection, audio quality control and much more to your product at a low cost and at low power and still with the flexibility of software programmability. They won’t replace CPUs for management and general processing, but it looks like they’re taking over everything to do with smart audio and video/imaging.This blog is the first in a series and continues with the next post: “When a DSP beats a hardware accelerator”.Guy Givoni works with CEVA Inc.
