  • Nova Scotia and British Columbia Work Together to Meet Labour Needs

    first_img promoting supplier development and industry engagement sharing of best practices in trades training evaluating international training models and assessing joint training ventures in the shipbuilding and marine industries promoting participation in shipbuilding and industrial marine trades training among youth and aboriginal people Nova Scotia and British Columbia have formalized an agreement to enhance partnerships across their shipbuilding and marine industries, and increase the mobility of apprentices. “We share a strong shipbuilding industry,” said Karen Casey, acting Minister of Labour and Advanced Education. “We need to take advantage of this and work together to help grow our two provinces’ economies. This partnership helps our businesses to build their export capacity and take full advantage of spin-off opportunities coming out of the industry.” In the memorandum of understanding, the two provinces commit to helping businesses tap into the supply chain, improving shipbuilding and industrial marine trades training, and removing barriers for apprentices training in the trades. “Shipbuilding and marine industries are important to the economies of both our coastal provinces,” added Shirley Bond, Minister of Jobs, Tourism and Skills Training for British Columbia. This partnership aligns with recommendations from the ONE Nova Scotia Coalition to take advantage of the economic opportunities presented by the shipbuilding project and to support the participation of Nova Scotia businesses in national and global supply chains. These include opportunities for more than 150 Nova Scotia businesses. The coalition predicts that the shipbuilding project will drive employment and supply chains across the province. “Cooperation between provinces on training to meet the increasing demand for skilled trades people is fantastic,” says Paul Phillips of Hawboldt Industries Ltd. “We are proud to have worked with shipyards on both coasts. We see lots of similarities that Nova Scotia and British Columbia businesses and apprentices can benefit from.” Commitments under the agreement also include: This partnership is consistent with government’s commitment to reduce regulatory burden to enhance and improve the province’s economic climate.last_img read more

  • Government of Canada experiments with new ways of managing wireless spectrum

    first_img Facebook The research being conducted at the Big Data Analytics Centre will allow the Government to predict where on the wireless spectrum there are unused radio waves that can be put to work to ensure that the wireless networks Canadians depend on are reliable and accessible, regardless of traffic load.Spectrum is a scarce resource, especially as the amount of data traffic on wireless networks continues to grow exponentially. In particular, the ubiquity of smartphones and other wireless devices has triggered an explosion in the amount of data travelling over wireless networks. That’s why the Government is investing in technology and infrastructure that allow Canada to optimize the limited amount of wireless spectrum available.The research being conducted at the Big Data Analytics Centre has potential applications in many other sectors of the economy beyond telecommunications. The technologies that enable wireless spectrum to be managed dynamically can be used for connected cars and other systems that rely on merging advanced machinery and networked sensors and software, known as the Internet of Things.Quotes“To power their smartphones, tablets, TVs and radios, Canadians rely on the judicious use of wireless spectrum. We can’t make more wireless spectrum, but we can make better use of it. To do that, we need to understand exactly how it’s being used and where. We need to know, in real time, where there are unused radio waves that could be put to work. Big data is the key to understanding that. It gives us the power to turn data into useful insights that allow us to predict where the surplus capacity will be at any given time. The research being conducted at the Big Data Analytics Centre has the potential to transform not only the telecommunications sector but all sectors of the economy.”– The Honourable Navdeep Bains, Minister of Innovation, Science and Economic Development Canada“The Communications Research Centre is honoured to have Minister Bains here to officially open the Big Data Analytics Centre, the first visualization laboratory of its kind within the Government. Using big data analytics, cloud computing, crowdsourced information, data fusion and state-of-the-art visualization, the Centre enables our researchers to work with big data in ways that were previously not possible to support sustainable spectrum management and help foster innovation in Canada.”– Dr. Jean Luc Bérubé, President, Communications Research Centre“Canada is fortunate that Innovation, Science and Economic Development Canada is focused on extending the benefits of our increasingly critical wireless infrastructure. Cognitive Systems is delighted to collaborate with the CRC, a world-class research organization, to better understand and monitor spectrum for effective use and growth.

  • SouthEast European States agree at UN summit to use waterways to promote

    13 June 2008The leaders or representatives of nine South-East European countries have pledged today at a United Nations-organized meeting to use the region’s waterways to encourage greater cultural understanding. The Athens Declaration, adopted by seven Heads of State and two high-level representatives, emphasizes the importance of rivers, lakes and maritime routes in contributing to regional cooperation.“No civilization and no culture is monolithic as both are the result of millennia of contacts and exchanges,” according to the declaration, which was reached at a summit in the Greek capital co-organized by the UN Educational, Scientific and Cultural Organization (UNESCO).Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Montenegro, Romania, Serbia and Turkey committed themselves to developing a pool of joint projects involving the waterways to contribute to regional peace and stability. read more

  • Slow pace of returns to northern Yemen two months after ceasefire –

    23 April 2010More than two months after a ceasefire was struck and one month after the official end to hostilities in northern Yemen, locals have been cautious and slow in returning to the area due to continuing security concerns, the United Nations refugee agency reported today. Nearly 300,000 people have been uprooted from their homes in the region by fighting between Government forces and rebels in recent years.Some 7,000 uprooted civilians sheltering in camps at Al Mazraq in Hajjah governorate have visited their homes in the north to assess damage to their farms and property, but the UN High Commissioner for Refugees (UNHCR) estimates that only one quarter have decided to stay in their hometowns and villages.“Most remain displaced amid continuing concerns about insecurity, ongoing skirmishes, landmines, lack of basic services and lack of shelter, as many homes were either destroyed or partially damaged,” agency spokesperson Melissa Fleming told journalists in Geneva.Internally displaced persons (IDPs) have also told UNHCR that they are unsure whether the peace will last.Their fears of landmines and unexploded ordnance in their home villages are being reinforced by frequent reports of deadly incidents, Ms. Fleming noted. This month alone, at least two children died and nine children and adults were injured.“In addition to the loss of lives, these incidents are adversely affecting the safety of returns and school attendance in areas which were affected by the conflict,” she said, adding that campaigns to raise awareness about are taking place in all areas where IDPs are sheltering to minimize casualties.Most of those displaced by clashes have been living in host communities with friends, relatives or neighbours, but the situation for many in Hajjah and Amran governorates is becoming untenable as resources are becoming depleted.Those without identification documents cannot register with authorities in Hajjah, preventing them from receiving humanitarian assistance, forcing them to sell their belongings, including their remaining cattle.“We fear that this group is becoming increasingly vulnerable and a potential target for abuse or exploitation,” Ms. Fleming said. UNHCR is working with the Yemeni Government to ensure their registration as IDPs and enhance their access to relief.The agency also warned today about the funding gap it faces for its operation in Yemen. Between August and December last year, it reached 100,000 displaced people, while this year it has helped 50,000 so far and has enough resources to assist an additional 30,000 by June.Just over one third of the nearly $40 million it needs for 2010 has been received. “Unless new funding is provided urgently, UNHCR will not be able to provide protection, shelter and humanitarian assistance to some 170,000 refugees and 280,000 IDPs in Yemen,” its spokesperson said.Earlier this month, a UN human rights expert cautioned that without an urgent injection of funds, IDPs in Yemen are in danger of “a grave humanitarian crisis.”Walter Kälin, the Secretary-General’s Representative on the Human Rights of Internally Displaced Persons, wrapped up a week-long visit to Yemen with a call for all sides to the conflict in the country’s north to observe and implement a ceasefire so that civilians in the region can enjoy a measure of peace.Mr. Kälin said in a statement at the end of his trip that the international humanitarian response over the past year and ongoing cooperation between the Yemeni Government and the UN had averted a disaster.“These achievements are now threatened by a dramatic shortfall of funding,” he said, noting that some aid agencies have announced they will have to close their operations within the next few months without new funds.“The consequences of such a withdrawal would be severe. IDPs by the very nature of their displacement, and in particular those who have suffered multiple displacements, have no more capacity to cope with their situation.” read more

  • Women more likely to die after heart attack because doctors see it

    first_imgThe research found that women were less likely than men to receive the recommended treatments after a heart attack.Women who had a the type of attack where the coronary artery is completely blocked by a blood clot, were 34 per cent less likely than men to receive procedures which clear blocked arteries and restore blood flow to the heart, such as bypass surgery or a stent.They were also 24 per cent less likely to be prescribed statins, which help to prevent a second heart attack, and 16 per cent less likely to recommended aspirin, which helps to prevent blood clots.Critically, when women did receive all of the treatments recommended for patients who have suffered a heart attack, the number of women dying decreased dramatically.Previous BHF research has also shown that women are 50 per cent more likely than men to receive the wrong initial diagnosis and are less likely to get a pre-hospital ECG, which is essential for swift diagnosis and treatment.Professor Jeremy Pearson, Associate Medical Director at the British Heart Foundation, said: “Heart attacks are often seen as a male health issue, but more women die from coronary heart disease than breast cancer in the UK.“The findings from this research are concerning – women are dying because they are not receiving proven treatments to save lives after a heart attack.“We urgently need to raise awareness of this issue as it’s something that can be easily changed. By simply ensuring more women receive the recommended treatments, we’ll be able to help more families avoid the heartbreak of losing a loved one to heart disease.” A large percentage of women were not prescribed statins Women were less likely than men to receive artery opening surgery or a heart bypass  Researchers worked with the Karolinksa Institutet in Sweden, and the findings are based on Swedish health records between 2003 and 2013.  But Sweden has one of the best healthcare systems in the world, so the experts believe the situation could be even worse in Britain.“Sweden is a leader in healthcare, with one of the lowest mortality rates from heart attacks, yet we still see this disparity in treatment and outcomes between men and women,” added Prof Gale.“In all likelihood, the situation for women in the UK may be worse.”The research was published in the Journal of the American Heart Association. Women are being left at risk of repeat heart attacks and early death because doctors see heart disease as a male problem, a new study has shown.Researchers from The University of Leeds and the British Heart Foundation claim women are dying because many are not offered stents to unblock arteries, or prescribed statins, after their first heart attack.Around 42,000 men and 28,000 women die from coronary heart disease in Britain each year, with most deaths related to an original heart attack.But the new study, which looked at data from more than 180,000 people over 10 years, found three times the expected number of women died in the first year of a heart attack, compared to men. Experts claim women are being denied life saving treatment because they are not considered at high risk.“We need to work harder to shift the perception that heart attacks only affect a certain type of person,” said Professor Chris Gale, Professor of Cardiovascular Medicine and Honorary Consultant Cardiologist at the University of Leeds who co-authored the study.“Typically, when we think of a heart attack patient, we see a middle-aged man who is overweight, has diabetes and smokes. This is not always the case. Heart attacks affect the wider spectrum of the population – including women.“The findings from this study suggest that there are clear and simple ways to improve the outcomes of women who have a heart attack ­­– we must ensure equal provision of evidence-based treatments for women.” Women were less likely than men to receive artery opening surgery or a heart bypass  Want the best of The Telegraph direct to your email and WhatsApp?

  • LETTER Gaskin exposes himself hangs AFC out on a limb

    Dear Editor,I have read with interest the comments made by President David Granger’s son-in-law, Minister Dominic Gaskin, in attempting to justify, and poorly so, the AFC denial of being consulted on President Granger’s unilateral appointment of Reverend James Patterson as the GECOM Chairman and denial of playing any part in the selection process, in face of the presence of AFC leader, Raphael Trotman, at the October 19th, 2017 meeting between the President and the Opposition Leader.The report by Stabroek News (November 13, 2017) states, and rightly so, that, as Natural Resources Minister, Trotman would have had no reason to be present at the meeting, in any capacity, other than that of AFC leader.Dominic Gaskin and Gail TeixeiraGaskin confirms that Trotman was present at the meeting between the President and the Opposition Leader because he is “the leader of the AFC” and “it is a recognition that we are a coalition government.”However, he then contradicts himself in defending the unilateral appointment of a GECOM Chairman by his father-in-law, by saying that the Constitution does not provide for consultations with any party, as the decision to choose a chairman is placed on the President.Gaskin cannot defend the AFC when it says it was not consulted and not part of the selection process used to arrive at a GECOM Chairman and at the same time defend his father-in-law as President. He cannot, using the proverbial term, “chew cane and blow whistle at the same time”. The AFC cannot be physically present when this egregious breach of the Constitution takes place and then pretend like “Pontius Pilate” that it washes its hands of its sin.This latest pronouncement by yet another AFC leader points clearly to another manifestation of the ‘PNC faction’ in the AFC. Dr. Henry Jeffrey and members of the AFC Canada Chapter recently publicly warned about this PNC faction.Gaskin has exposed himself as an apologist for his father-in-law, President Granger, and the PNC, and, has gone so far as to hang his own party, the AFC, out on a limb.Regards,Gail Teixeira, M.P.

  • Ausdrill develops walking drill rigs for salt lake gold exploration

    first_imgInnovative technology developed by Ausdrill is opening up previously inaccessible salt lakes for exploration drilling. Custom-built drill rigs, nicknamed lake walking machines, allow drilling for potential mineral deposits to be carried out in lakes and other locations with deep mud covering. The lake walking machines are designed and manufactured by Ausdrill subsidiary, Drill Rigs Australia, at a facility in Canning Vale in Perth’s southern suburbs.They are already in use on salt lakes in the Goldfields of Western Australia, with Ausdrill conducting drill campaigns for major clients such as Gold Fields and AngloGold. To date exploration has taken place at both Lake Carey and Lake Lefroy. To overcome the problems inherent in drilling in locations where there is substantial mud coverage, the lake walkers have been designed to “walk” on the surface of a lake. A key to the technology is the use of 2.2 m wide tracks which stop the rigs sinking in to the mud.“The rigs weigh up to 25 t each,” said Eddie Banner, General Manager of Drill Rigs Australia (DRA). “A traditional drill rig would sink straight into the mud.” Ausdrill has been developing equipment over the past 15 years to access the salt lakes around Kambalda, in order to explore for gold deposits. A range of different technologies have been employed in the past to allow drilling to be carried out in the lakes. This has included the use of hovercraft platforms, and the construction of temporary causeways to move conventional drill rigs out onto the lake.“If you build a causeway, you have to remove it later. These new machines eliminate the need for the whole process of building and removing a causeway, and they save the mining companies a lot of money as a result,” Banner said. DRA are leaders in the design and manufacture of these specialised machines. With growing demand, Ausdrill now has eight of the rigs available. “We are seeing increasing interest from our clients for exploration drilling in lakes and sandy areas,” said Ausdrill General Manager Brian Mann. “Our expertise in this field, combined with the specialised equipment we have developed, has put Ausdrill in a very strong position to deliver drilling programs in what would otherwise be fairly inaccessible locations.”Riding on their super-wide tracks, the lake walking rigs have a footprint of 53 square metres in order to minimise the pressure on the lake surface. This is approximately 90 times the foot print that an average car has on the road via its four tyres. The drill rigs are accompanied by a number of support vehicles which carry drill rods and other equipment, fuel, water and personnel. “Once we’ve set up on site, the drill rig and the support vehicles must remain stationary for days or even weeks at a time to complete each hole, so it is vitally important that they do not sink into the muddy lake surface,” Mann said.last_img read more

  • DESWIK launches new survey functionality for underground mining

    first_imgDeswik has announced the launch of new survey functionality with its latest software release, Deswik.Suite 2016.1. “Integrating seamlessly with Leica instruments, Deswik.CAD now features in-built survey functions commonly used by underground surveyors internationally. Built on the powerful CAD and plotting engine, the new functionality includes: survey job management, in-built stations database, attribute values varying along polylines as well as advanced features such as automatic solids creation from tunnel as-builts.” These allow for dynamic data updating and rapid plot generation.In May 2015, Stephen Rowles and Luke Waller from Independence Group NL began work at the new Nova Project in Western Australia. They were tasked with setting up best of breed systems for the survey department. As Deswik was already in use by the planners, its survey functionality was reviewed and found to show potential. Working in conjunction with the Deswik development team, their core CAD platform was enhanced to suit the site needs and simplify the typical surveying processes. “At Nova, we began working with Deswik in July 2015, the purpose was to provide technical assistance to the development team to create a platform for underground surveying” explains Stephen Rowles, Senior Surveyor at the Nova Project. “This would allow data in the mining sequence to flow seamlessly between the departments, while at the same time performing all of the functions that we need as surveyors.  Several core software functions have been built into the CAD package which has improved our processing time and the integrity of the data.  The lateral development side of Deswik.CAD is now robust and a proven commodity, we are now focusing our attention to the production side of the package and get it to the same standard already in place.”“The feedback on site has been very positive from all parties involved and we are looking forward to building on the quality product that is already in place.  The opportunity to create a new survey package has been a rewarding endeavour and being the first mine in the world to use this for surveying is quite an experience”. The survey functions in Deswik.CAD enable data generated by the engineers and surveyors to be used by each other without the need for file conversions. This has allowed seamless integration when transferring data between the mining departments.The new survey functionality was released with another 141 enhancements to the Deswik software suite and two new underground tools: Deswik.Caving (cave flow modeling) and Deswik.UNO (underground network optimisation).last_img read more

  • Eurogroup dashes Greek hopes for funding gap fix

    first_imgTop-ranking European officials meeting in Luxembourg suggested on Monday that no decision regarding Greece’s bailout program would be made before the end of the year, while also dashing Greek hopes of rolling over bonds due to mature next spring in order to cover a funding gap next year.On arriving at a summit of eurozone finance ministers in Luxembourg, ECB executive board member Joerg Asmussen ruled out the possibility of rolling over bonds due to mature next spring to cover a funding gap which Greece estimates at around 4.4 billion euros. Asmussen put the funding gap closer to 6 billion euros and said that other methods must be found to plug it.“We must find a way to close the financing gap and there is absolutely no way it can be done in a way of roll-over bond or whatsoever which results in monetary financing; this is not possible for the ECB and not for the whole euro system,” he said.Asmussen said officials meeting in Luxembourg were to have “a first exchange of views” on how to close the financing gap of the existing program.European Monetary and Economic Affairs Commissioner Olli Rehn struck a similar tone. “We will reflect in the coming weeks to see and decide how to proceed with Greece concerning its financing needs and potential fiscal gap,” he said.Source: ekathimerini Facebook Twitter: @NeosKosmos Instagramlast_img read more

  • Maladie de Parkinson de nouvelles pistes pour diminuer les troubles de la

    first_imgMaladie de Parkinson : de nouvelles pistes pour diminuer les troubles de la marcheFrance – Deuxième cause de handicap d’origine neurologique chez les personnes âgées, la maladie de Parkinson touche près de 150.000 personnes en France. Les tremblements et les raideurs caractéristiques de la maladie sont dus essentiellement à l’altération dans le cerveau d’un type particulier de neurones. Aujourd’hui, l’équipe de Chantal François et d’Etienne Hirsch suggère que les troubles de la marche, observés chez les patients à un stade avancé de la maladie, seraient liés à la dégénérescence d’un autre type de neurones, lesquels pourraient constituer une nouvelle cible potentielle pour le traitement pharmacologique des patients.  Dans la maladie de Parkinson, les symptômes moteurs sont dus à la mort de certains neurones  utilisant la dopamine comme messager chimique : les neurones dopaminergiques. Ces symptômes disparaissent généralement grâce au traitement par la dopamine. Cependant, dans les formes avancées de la maladie, une résistance à ce traitement apparaît : des troubles de la marche et des chutes surviennent alors. L’hypothèse la plus probable est qu’il existe une structure non liée à la dopamine et impliquée dans le contrôle de l’équilibre. Le noyau pédonculopontin (PPN), structure cérébrale constituée en partie de neurones dont le messager chimique est l’acétylcholine  (neurones cholinergiques), constituait alors un candidat potentiel pour les chercheurs.Pour déterminer son rôle dans le contrôle de la marche et de la posture, les chercheurs et cliniciens ont utilisé une approche expérimentale multidisciplinaire originale. Celle-ci combine des techniques d’IRM fonctionnelle, d’anatomie et de neurochirurgie. Sur la base d’analyses réalisées chez les sujets sains et malades, plusieurs observations ont permis de conclure à l’importance de ce noyau dans le contrôle de la marche et de la posture. Elles ont aussi permis de conforter l’hypothèse selon laquelle les troubles de la marche observés au cours de la maladie de Parkinson étaient dus à une lésion ou à un dysfonctionnement de cette petite structure cérébrale.Grâce à des études réalisées sur des sujets sains, les chercheurs ont montré que le noyau “s’active” lorsque les sujets s’imaginent marcher le long d’un couloir. Cette activation croît d’autant plus que la marche imaginaire s’accélère. Une analyse du tissu cérébral prélevé post-mortem a par ailleurs montré que seuls les patients parkinsoniens ayant souffert de troubles de la marche et de l’équilibre présentent une perte de neurones cholinergiques dans le noyau pédonculopontin. Chez des primates âgés parkinsoniens, on observe également une forte corrélation entre la perte d’équilibre et la perte de neurones cholinergiques du noyau. Enfin, les chercheurs ont prouvé que la lésion expérimentale des neurones cholinergiques dans cette structure conduit à des troubles de la marche et des déficits posturaux.”Ces résultats sont très prometteurs et constituent une nouvelle piste de recherche pour développer des stratégies thérapeutiques différentes. Par exemple, chez les patients parkinsoniens à un stade avancé de la maladie, on peut imaginer stimuler les neurones cholinergiques au niveau du tronc cérébral pour améliorer de façon efficace leurs troubles de l’équilibre” concluent Chantal François et Etienne Hirsch.  Le 18 juillet 2010 à 12:33 • Emmanuel Perrinlast_img read more

  • Rare Jungle Island gator undergoes CT scan

    first_imgWATSON ISLAND, Fla. (WSVN) — South Florida’s Jungle Island brought in some high-tech help to care for one of the park’s most popular residents, Friday.Casper is a rare leucistic alligator, and his caretakers are concerned because he’s losing weight. “For about six weeks he’s been, you know, loss of appetite, a little bit lethargic and a little bit a loss of weight,” Jungle Island spokesperson Jason Chatfield said.The 19-year-old reptile has a history of melanoma cancer, so the park called Mobile Pet Imaging, a South Florida-based mobile veterinary imaging service, to give Casper a CT scan.“These guys are mobile, so they can drive up to us,” Chatfield, “We only have to take Casper 35 yards instead of 15 miles, which is great, less anesthesia, less stress.”The scan works by reconstructing a three-dimensional image of Casper’s head to better diagnose him. Doctors receive a scan with details and angles that wouldn’t be seen in a traditional X-ray.“We’ll probably get the results, look at them and send them off to a radiologist who’s done gators before on a CAT scan,” Chatfield said, “And they’ll compare them to see what’s normal and what’s abnormal.”Veterinarians will study the results of the scan and determine what course of medical action to take, if any.

Members of the Assembly say they’re hearing more complaints from constituents about shop-lifting, break-ins and car theft. Committee chair Eric Croft suspects that an uptick in opioid and synthetic cannabinoids like Spice may be playing a role.“Is this epidemic fueling some of the property crime and car thefts that we’re seeing? I don’t know the answer, but I’d like to get to it,” Croft said.The city has seen an uptick in both both Spice and opioid overdoses the last few weeks. Though nowhere near levels of the “Spice crisis” in 2015, medics treated more than 60 people for suspected cannabinoid overdoses in June. Neither police nor fire department officials, who are in charge of ambulance crews, can say what’s prompting the resurgence.There’s also a new spike in opioid overdoses. Since April, the number of times paramedics treated patients with the over-dose reversing drug Nalaxone has shot upwards, nearly doubling over recent years — up to five per day. Public safety officials think the rise might be because of the synthetic opioid Fentanyl hitting Anchorage, but can’t say definitively.Anchorage Police Chief Justin Doll said the department doesn’t have conclusive proof there’s a connection between drugs and property crime. But he said violations like car thefts are overwhelmingly connected to other illegal behavior.“Typically what we’re seeing is they’re being used to commit other crimes, and just as a means of transport to and from other crimes,” Doll said.APD said so far this year they’ve recovered 92 percent of all the vehicles reported stolen, but that for the second year in a row the level of thefts is surging.No policy solutions were offered at Wednesday’s meeting. Instead, Assembly members are hoping to get a more accurate diagnosis of how addiction might be affecting crime and figure out a course of action from there.Chief Doll said his department is in the process of deciding on the most effective way to deploy the newly expanded force, which has seen a wave or new hires from recent police academies.last_img read more

  • Stop it now The kid will go blind Saif Ali Khan loses

    first_imgSaif Ali Khan, Kareena Kapoor and son TaimurInstagramSaif Ali Khan and Kareena Kapoor Khan’s son Taimur is paparazzi’s favourite, but recently the star kid’s father lost his cool over his son being constantly clicked.Saif and Kareena, along with Taimur, were recently spotted at the airport. As usual, photographers jumped in to click pictures of the kid, but too much flash on Taimur’s eyes irked Saif.An angry Saif told the shutterbugs to stop clicking so many pictures, saying “the child will go blind”. “Bas karo yaar, bachcha andha ho jayega (Stop it now! The kid will go blind),” Saif told the camerapersons, according to Desi Martini.The drama did not end there. When the photographers asked Saif and Kareena to pose, the actor replied in negative saying, “Aap ko lena hai toh lo, ye pose karna thoda weird hai (You can take pictures, but it’s weird to pose)”.Well, too much of attention from media often gets into stars’ nerves, but shutterbugs too have to do their job, isn’t it?Taimur is just 2 years old, but the star kid’s popularity is unmatchable. He often remains in news for various reasons. Recently, it was reported that Madhur Bhandarkar was planning to make a film titled “Taimur”.The film-maker reportedly had registered the title for one of his upcoming films. However, it was not clear if the film would actually be based on Kareena’s son, or it is about something else.last_img read more

  • 8Bitdo Will Release an Arcade Stick for Nintendo Switch on August 20

    first_img The Nintendo Switch has become a great platform for fighting games. Titles like Ultra Street Fighter II, Garou: Mark of the Wolves, Samurai Showdown IV, and even Arms work wonderfully on the Pro controller. Despite that, even this controller doesn’t replicate the classic arcade feel of a proper arcade fight stick. Thankfully, our friends over at 8Bitdo are about to release an arcade stick for Nintendo’s latest (and greatest?) system.The NES30 Arcade Stick is everything a fighting game fan could ever want. It features eight 30mm sized buttons, and of course, a standard joystick. This controller is also highly customizable. Users can swap out the joysticks with Sanwa joysticks and even customize the buttons. It also features turbo functionality and joystick/d-pad modes.AdChoices广告Like 8Bitdo’s other controllers, the NES30 Arcade Stick is wireless. Those who prefer to play wired can use the 3 meter USB cable that comes with the controller, or any USB cable of their choice. Though this arcade stick is being marketed to the Switch audience, it is compatible with many other devices. This includes Windows PCs, Android, macOS, and Steam. Considering how this controller costs $80, it’s nice to know it can be used on multiple platforms.While the NES30 Arcade Stick is decidedly on the expensive side, it will be worth every penny to fighting game aficionados. Like I said earlier, the Switch has a ton of kick-ass (pun intended) fighting games. I’m sure the selection of fighters will only continue to grow over time. Because of that, this arcade stick will be essential for those who want to play fighting games the way they were meant to be played.The NES30 Arcade Stick will be released on August 20. You can pre-order it now from Amazon. Expect a full review from us soon.Let us know what you like about Geek by taking our survey.
