Greeks find Olympic Village situation ’tragic’

first_imgThe Greek athletes and officials who have arrived in Rio ahead of the start of the Olympic Games on Friday have come up against terrible conditions in the Olympic Village, to the extent that they had to move to another floor in their building due to their original rooms flooding.The warnings from the international press about the poor preparation by the Brazilians have proved accurate, as the Greek mission testifies, with its head, Isidoros Kouvelos speaking on Sunday about major problems never seen before in Olympic Villages.“The situation is tragic, as far as our accommodation at the Olympic Village is concerned,” said Kouvelos at an interview with Athina 984 radio station.“Outside it is like a jewel, but inside it is like a building site. The plumbing is out of order, water runs everywhere, there are no mirrors in the bathrooms… Consider that we had to move to another floor because ours flooded.“That’s nothing in front of what other missions are suffering, such as the Japanese one that had to deal with a gas leak. Every morning at the meeting of the mission chiefs there are many complaints heard, and the hosts simply assure us that the problems will be solved.“What we have come up against is unprecedented, and of course we never faced anything like it in London or in Beijing, and certainly not in Athens. Workers have abandoned their work at the Village because they have not been paid and some of them have even made off with some of the materials,” said Kouvelos, who is also the head of the Hellenic Olympic Academy.The men’s national water polo team faced another problem, as the coach driver grated to it by the organizers was unable to find the way to the training center, meaning the team missed its training session.“The problem with transport is huge, and the team missed its training. They [the organizers] apologized a thousand times, but what good is that to us?” Kouvelos stated.Source: KathimeriniTweetPinShare0 Shareslast_img read more

Grants to Support Community Gambling Support Projects

first_imgThe Gambling Awareness Foundation of Nova Scotia is seeking applications for $300,000 worth of grants to fund projects to help Nova Scotian adults harmed by gambling. The one-year grants of up to $50,000 will be used to help address the factors that contribute to risk, improve local environments and deliver programming to prevent gambling harms. “There are many dedicated organizations across the province that have a good understanding of what’s happening in their communities and some really interesting ideas about how they can help people who are at risk or who struggle with gambling,” said Health and Wellness Minister Leo Glavine. “We know some people don’t think they are experiencing harm, or are reluctant to reach out to the formal health system. “That’s why we launched the Take 5 awareness campaign last year, and why I am looking forward to seeing new projects that could help even more.” Registered charities, community health boards and non-profit organizations are invited to submit proposals to address unmet needs, fill gaps in service or create awareness surrounding problem gambling. The grant program will be co-ordinated by the Nova Scotia Health Research Foundation. The foundation has more than 15 years of experience in conducting funding competitions and high-calibre peer review services in Nova Scotia. For more information on the grants, visit or contact Leslie Power at 902-424-4193 or . A 2013 adult gambling surveillance report found 73 per cent of Nova Scotians aged 19 years and older engaged in one or more gambling activities. This represents a 14.2 per cent decrease in gambling participation since 2007, primarily due to a reduction among low and no-risk participants. It is estimated that 50,000 Nova Scotians are at some risk of harm related to their gambling, and 5,000 could be experiencing severe harm. The 2013 adult gambling information collection report and the 2011 adolescent gambling surveillance report can be found at Take 5 is an interactive website with live chat, online forums, and motivational text messages in addition to traditional telephone support.

Ironies and pressure points

first_imgThere are doubts in the minds of foreign policy minions in the Indian government who, till now, were elated with having told the visiting US Secretary of State Mike Pompeo that there was no scope of cancelling the S400, Air Defence Weapon System procurement deal with Russia as it was in their National Interests to procure the S400. This issue had grown out from the CATSAA in an otherwise placid relationship. The US Congress had passed this as a law on August 2, 2017, and President Donald Trump had acquiesced albeit, gingerly. “Title II of the Act primarily deals with sanctions on Russian interests such as its oil and gas industry, defence and security sector, and financial institutions, in the backdrop of its military intervention in Ukraine and its alleged meddling in the 2016 US Presidential elections”. Section 231 of the Act empowers the US President to impose at least five of the 12 listed sanctions—enumerated in Section 235 of the Act—on persons engaged in a “significant transaction” with Russian defence and intelligence sectors. Two of the most stringent of these sanctions are the export licence restriction by which the US President is authorised to suspend export licences related to munitions, dual-use, and nuclear-related items; and the ban on American investment in equity/debt of the sanctioned person. Also Read – A special kind of bondThe US President has delegated his powers to the Secretary of State to implement Section 231 in consultation with the Treasury Secretary. In this section, the Department of State has notified 39 Russian entities, dealings with which could make third parties liable to sanctions. These include almost all of the major Russian companies/entities such as Rosoboronexport, Almaz-Antey, Sukhoi Aviation, Russian Aircraft Corporation MiG, and United Shipbuilding Corporation which are active in manufacturing defence items and/or their exports. These are all major suppliers to the Indian Government Also Read – Insider threat managementThis pressure point from the US was jarring as it arose whilst an Indian External Affairs brief had extolled that “India-U.S. bilateral relations have developed into a “global strategic partnership”, the Defence relationship has emerged as a major pillar of India-US strategic partnership with the signing of ‘New Framework for India-US Defence Relations’ in 2005 and the resulting intensification in defence trade, joint exercises, personnel exchanges, collaboration and cooperation in maritime security and counter-piracy, and exchanges between each of the three services. The Defence Framework Agreement was updated and renewed for another 10 years in June 2015″. And that the two countries now conducted more bilateral exercises with each other than they did with any other country. Bilateral dialogue mechanisms in the field of defence were all pervasive and it included Defence Policy Group, Defence Joint Working Group, Defence Procurement and Production Group, Senior Technology Security Group, Joint Technical Group, Military Cooperation Group, and Service-to-Service Executive Steering Groups. The agreements signed during the past one year include, Logistics Exchange Memorandum of Association (LEMOA) signed in August 2016, Fuel Exchange Agreement signed in November 2015, Technical Agreement (TA) on information sharing on White (merchant) Shipping signed in May 2016 and the Information Exchange Annexe (IEA) on Aircraft Carrier Technologies signed in June 2016. In February 2017, the LEMOA led to a Master Ship Repair Agreement between the Indian firm Reliance Defence and Engineering Ltd (RDEL) and the US Navy to provide repair and alteration service at its Pipavav Shipyard for the ships of the US Seventh Fleet consisting of some 100 vessels operating in the Western Pacific and the Indian Ocean regions. This contract is likely to generate in excess of 10,000 crores in revenue to RDEL in the next five years. On the other hand, one does not see a planned reciprocal opportunity accruing to the Indian Navy in the near future. The aggregate worth of defence acquisition from U.S. Defence has crossed over US$ 13 billion( 2017) and they included 13 C 130 J Hercules aircraft, 10 C -17 Globemaster, 12 P-8 Poseidon aircraft from Boeing, 22 AH 64 Apache helicopters, 15 CH 47 Chinook helicopters, 145 M777 Howitzers. Also in 2012, Tata Advanced System Ltd (TASL) and Lockheed Martin established a JV to produce C 130 airframes components. TASL also established a JV with M/s Sikorsky to produce S-92 helicopter cabins. The United States agreed to supply India with the General Atomics MQ-9 Guardian/Predator-B long-range unmanned combat aerial vehicle (UCAV). This UCAV equipped with advanced marine avionics has both air and sea variants and can be armed with up to four AGM-114 Hellfire air-to-surface missiles and laser-guided bombs. But at this stage, the US government insisted on signing the COMCASA agreement. Without this agreement, the US indicated that it could not part with highly coded communication equipment with the military platforms they sell to India, whilst claiming it will also allow India access to the big database of American intelligence, including real-time imagery. In fact, it went on to include all previous acquisitions of aerial platforms including the C-130Js, Globemaster, P-8 Poseidon, AH 64 Apache helicopters and CH 47 Chinook helicopters in this agreement. We would recall that during the C -130J contract Indian Defence Minister had declined to sign COMCASA and had accepted to function without the special communication equipment. The COMCASA will effectively mean that, like it or not, India also shares real-time intelligence it acquires with the USA. (The author is a retired Air Commodore and strategic affairs commentator.

Northern Health warning residents about bluegreen algae

first_imgPRINCE GEORGE, B.C. – Northern Health has issued a bulletin to remind residents about precautions they need to take if they encounter blue-green algae when they head out for a swim in their favourite lake.The health authority said that with temperatures getting warmer during the summer months blooms of cyanobacteria, or blue-green algae, may appear in lakes across Northern B.C. Blue-green algae are naturally occurring and can look like scum, grass clippings, fuzz or globs on the surface of the water. The blooms can be blue-green, greenish-brown, brown, or pinkish-red, and often smell musty or grassy.People who come in contact with visible blue-green algae, or who ingest water containing blue-green algae, may experience skin irritation, a rash, a sore throat, sore red eyes, swollen lips, and potentially develop a fever, nausea and vomiting, or diarrhea. Symptoms usually appear within one to three hours and resolve in one to two days. Residents living near the shores of lakes, as well as visitors and those making day-use of lakes, are advised to take the following precautions:Avoid all contact with blue-green algae blooms. If contact occurs, wash with tap water as soon as possible.Do not swim or wade (or allow your pets to swim or wade) in any areas where blue-green algae are visible.As a reminder, Northern Health recommends that visitors and residents do not drink or cook with untreated water directly from any lake at any time. Boiling lake water will not remove the toxins produced by blue-green algae.An alternate source of drinking water should also be provided for pets and livestock.  Pet owners should be wary of allowing pets to walk off-leash where they may be able to drink lake water – illnesses are a common outcome.Anyone who suspects a problem related to blue-green algae can connect with the Ministry of Environment at If you require further information on health concerns, please call Environmental Health at 250-565-2150.

RIM stock on fire in New York after big Toronto gains

Justin Sullivan/Getty Images TORONTO — Research In Motion shares in New York played catch-up Friday to the dramatic surge seen in Toronto a day earlier.On the Nasdaq market, which reopened after being closed Thursday for the U.S. Thanksgiving holiday, RIM shares closed up almost 14% at US$11.66 during a shortened trading session.After surging 17% on the Toronto Stock Exchange on Thursday, RIM shares on that market gave back 44 cents, or 3.7%, to $11.56 in early afternoon trading.“People are looking at that stock in two ways,” said Sadiq Adatia, chief investment officer of Sun Life Global Investment.“One way is that (RIM is) tightening its belt,’ Adatia said, adding that the company is ”doing a bit of reputational damage repair“ either in hopes of being bought out or ”they truly feel the new product launch they will be having should actually do quite well.“We think there is more money to be made ahead of the 2013 launch of BB10The Waterloo, Ont., company’s new BlackBerry 10 operating system — which will be unveiled at a Jan. 30 event along with its new line of smartphones — is widely considered a make or break product launch for Research in Motion.The Thursday spike in Toronto came after a week of steady gains amid more positive sentiment, but analysts are still guarded about the potential success of RIM’s new operating system.On Thursday, National Bank Financial analyst Kris Thompson said he was boosting his price target for RIM to US$15 per share from US$12.“We think there is more money to be made ahead of the 2013 launch of BB10,” Thompson said in a research note.Earlier this week, prominent tech analyst Peter Misek gave RIM’s new operating system a small but improved chance of success as he raised his target price to US$10 from US$5.Misek, of New York-based Jeffries & Company, said he was surprised by the strongly positive initial feedback on RIM’s new BB10 handset from carriers. Still, he’s giving the BlackBerry 10 operating system only a 20 to 30% probability of successfully taking on Apple and Android-based phones.There have been repeated delays in bringing the new RIM smartphones to market and the company has suffered two embarrassing service outages.RIM’s latest outage was in September, the same day that Apple’s new iPhone launched in stores. In Oct. 2011, RIM’s outage lasted several days affecting millions of users globally. read more

TSX falls as worrying China data drives down commodities

TORONTO — Mining stocks pushed the resource-heavy Toronto stock market slightly lower Monday while commodities fell amid weak Chinese trade data and disappointing Japanese growth figures for the fourth quarter.The S&P/TSX composite index gave back 14.89 points to 14,284.19, following a 0.6 per cent rise last week.The weak economic data from overseas coupled with Friday’s weak employment report pushed the Canadian dollar down 0.17 of a cent to 90 cents after sliding 0.1 per cent last week.New York indexes were also in the red as the Dow Jones industrials lost 78.9 points to 16,373.82, the Nasdaq was down 12.92 points to 4,323.3 while the S&P 500 index was off 6.3 points to 1,871.74.Data released on the weekend showed China’s exports fell by an unexpectedly large 18 per cent in February.China’s official 2014 economic growth target of 7.5 per cent assumes trade also will grow by 7.5 per cent. But customs data show combined imports and exports so far this year have shrunk by 4.8 per cent.“The focus will likely remain on China in an otherwise quiet week, with January-February activity data due on Thursday,” said a commentary from Barclays Research.“We expect the message to be moderately slower growth, given the soft demand outlook suggested by the recent PMI readings, and lower inflation.”Meanwhile, Japan reported Monday a record current account deficit for January, and lowered its economic growth estimate for the October-December quarter to 0.7 per cent from one per cent.The base metals sector led TSX losers, down 2.4 per cent as copper prices fell for a second session in the wake of the Chinese data, with the May contract in New York losing another three cents to US$3.05 a pound. Prices for the metal tumbled 14 cents Friday after Chinese authorities allowed the country’s first corporate bond default, which fuelled speculation as to how many more companies may be in a similar situation.The energy sector lost 0.3 per cent while the weak overseas data pushed the April crude contract on the New York Mercantile Exchange down $1.48 to US$101.10 a barrel.Bullion prices were little changed with the April contract off 20 cents to US$1,338 but the gold sector eased 0.5 per cent.There were minor gains in the consumer staples and financial sectors.On the corporate front, Quebecor (TSX:QBR.B) shares dipped four cents to $25.26 a day after Pierre Karl Peladeau, until recently the head of the media conglomerate, announced that he’s going to run for the Parti Quebecois. Peladeau resigned Sunday morning as vice-chairman of the conglomerate founded by his father. Peladeau remains a shareholder.The Second Cup Ltd. (TSX:SCU) recorded net income of $1.18 million or 12 cents a share, improved from the year earlier loss of $12 million a year ago when Second Cup recognized the impaired value of its assets. Adjusted earnings per share was 17 cents, down from 18.2 cents per share a year earlier. Its shares were down 23 cents $38.58.In the U.S., Chiquita agreed to combine with Dublin-based Fyffes to become the world’s top banana company. The stock-for-stock transaction creates a global banana and fresh produce company with $4.6 billion in annual revenues. Chiquita rose $1.48, or 12.8 per cent, to US$12.23. read more

Lawyer to investigate significant misconduct by BC real estate agents

Volunteers can contribute to the new global development agendas success – UN

“By creating environments for people to volunteer their time, it is possible to use their skills and knowledge for the common good in the sphere of governance,” Richard Dictus, UNV Executive Coordinator said today on the release of the report.“Change will occur with greater civic engagement broadening the number of people who have voice, who can participate and who can hold governance actors to account.”The State of the World’s Volunteerism Report 2015 is the first global survey of the contribution of volunteers to better governance, a prerequisite for the success of the new sustainable development goals to be agreed at the United Nations in September. According to the study, the new agenda will only succeed if it looks into ways to engage communities more effectively, including through the power of volunteers and volunteering.More than 1 billion people volunteer globally, the majority of them working in their own countries. Drawing on evidence from countries as diverse as Brazil, Kenya, Lebanon and Bangladesh, the UN report, entitled Transforming Governance, shows how ordinary people are volunteering their time, energies and skills to improve the way they are governed at local, national and global levels.“Volunteers have a critical role to play in representing the voices of those who are often excluded from development decisions, including women and other groups who may be marginalized,” said UN Development Programme (UNDP) Administrator Helen Clark at the launch of the report in New York today.The report finds that countries such as Peru, Mozambique and Norway that provide a supportive “enabling environment” for volunteers tend to reap the rewards of their inclusion in decision-making.But too many others are failing to acknowledge – and leverage – the immense potential of volunteers. Therefore, the study calls on all governments to “go beyond the rhetoric of participation” and take concrete steps to help the world’s volunteers actively contribute to the decisions that affect people’s lives.Engaging more volunteers in the process of crafting policies and putting them into action would help would be a first step, notes the report. Integrating them into national development frameworks and sustainable development goals (SDGs) strategies would be another, as well as engaging more volunteer women and marginalized groups in local and national decision-making, it concludes. read more

Rohingya refugees drown as boat capsizes in rough waters off coast of

AUDIORohingya refugees receiving mental health first aid “UNHCR [the Office of the UN High Commissioner for Refugees] staff and our partners rushed to the scene to provide medical support, food, blankets and clothes to the survivors,” spokesperson Babar Baloch told reporters at the regular press briefing in Geneva. According to survivors, six families – 42 people in total, many of them women and children – left on a fishing boat from Gozon Dia south of Maungdaw town in Myanmar’s northern Rakhine state around 2 am Tuesday morning. They ran into rough seas and approached shore in the Imamerdail area of Ukhia sub-district in Bangladesh around 8.30 am local time when they ran into rough seas. A 15-year-old boy died on the spot and 22 were injured, several when they hit the engine Three were reported to have died en route to hospital, Mr. Baloch reported, adding that the remaining 19 injured were taken to UNHCR’s transit centre near Kutupalong camp. “We will ensure that families are not separated in the course of the medical treatment.” Meanwhile, the UN International Organization for Migration (IOM) reported that although the number of new arrivals is now slowing, people continue to arrive in the makeshift settlements of Bangladesh’s Cox’s Bazar every day, bringing the total Rohingya population of the district to over 820,000. The settlements are dangerously congested and overcrowded and the pressure on sources of clean drinking water and basic sanitation are enormous. Having walked for days without water and food, the refugees arrive to the settlements exhausted and thirsty. Many are ill, IOM stated. “All of the spontaneous and makeshift sites where the Rohingya have sought shelter are in urgent need of water, sanitation and hygiene (WASH) support to prevent diseases and to restore basic human dignity,” explained IOM WASH expert Antonio Torres. “Existing [sanitation and hygiene] facilities are not yet sufficient to cope with this number of people,” he noted. “All of the spontaneous and makeshift sites where the Rohingya have sought shelter are in urgent need of water, sanitation and hygiene (WASH) support to prevent diseases and to restore basic human dignity,” says IOM WASH expert Antonio Torres. “Existing WASH facilities are not yet sufficient to cope with this number of people,” he noted. IOM is providing vital relevant services to both the Rohingya and the communities hosting them, while scaling up its work to meet the needs of new arrivals. Since early September, the agency has, among others, constructed around 785 latrines for the refugees. It has also constructed 14 wells with hand pumps providing over 14,000 people with clean drinking water. read more

He was also ordered to pay £8,000 (over €9,000) in costs.Detective Inspector Neil John, from the Met’s Sexual Offences, Exploitation and Child Abuse Command (SOECA), said Amrani “used his status and position to indecently and sexually assault his victims, believing he could act with impunity”.“This was aggravated by his senior position … and the victims’ fear that if the matters were reported, they would not be believed or supported.“Evidence was heard at the court of instances of bullying, intimidation and threats of staff not being able to progress within their chosen careers if they made formal complaints. “Amrani was a gifted doctor and surgeon but for someone who is supposed to care for people, he showed absolutely no regard for his victims.“I would urge anyone who has suffered sexual abuse or violence to come and speak to us – we will listen and no matter who the offender is or their position, they will be brought to justice.”Suspicion of rape Detectives launched their investigation into Amrani in April 2015. Amrani was initially arrested on suspicion of rape in May 2015 and he denied the allegations. However, during the course of the investigation, officers identified other victims who alleged that they had been indecently assaulted by Amrani.The offences relate to his time working at Harefield Hospital and the Cromwell private hospital in Kensington, west London.In one account, officers were told that after Amrani had indecently assaulted a colleague whilst a patient was undergoing treatment in an operating theatre, he then told her that she should be ‘careful’ as he may be sitting on a forthcoming interview panel she was attending.Amrani was eventually charged in June 2016 with rape, sexual assaults and indecent assaults.He was found not guilty of one count of rape, four counts of indecent assault, two counts of assault by penetration, and one count of sexual assault.Read: Sterling tumbles in wake of UK electionRead: May’s gamble backfires as Corbyn surge sees hung parliament Dr Mohamed Amrani Image: Metropolitan Police Short URL Tweet thisShare on FacebookEmail this articlelast_img read more

Autisme létude qui le liait à un vaccin aurait été truquée

first_imgAutisme : l’étude qui le liait à un vaccin aurait été truquéeEn 1998, une étude publiée publiée dans la revue médicale britannique The Lancet établissait un lien entre le vaccin ROR (rougeole-rubéole-oreillons) et l’autisme infantile. Une découverte qui avait semé la panique en Grande-Bretagne, et avait entraîné une importante baisse des vaccinations. Douze ans plus tard, le British Medical Journal accuse les auteurs de cette étude de “trucage élaboré”.En février 2010, The Lancet s’était formellement rétracté et avait décidé de retirer l’article, cinq ans après avoir déjà regretté la publication de cette étude dirigée par le Dr Andrew Wakefield. Ce dernier évoquait un possible lien entre le vaccin ROR et l’autisme infantile, engendrant une importante polémique et une forte diminution de cette triple-vaccination dans le monde anglo-saxon. Suite à la publication de cet article, d’autres études ont été menées en Grande-Bretagne, au Canada, et aux Etats-Unis notamment. Aucune de ces recherches n’a permis d’établir une corrélation entre l’autisme et le vaccin ROR.À lire aussi3 idées reçues totalement fausses sur les vaccinsLa revue scientifique a retiré l’article suite à un jugement du Conseil général de la médecine britannique. Celui-ci évoquait certains éléments “inexacts” et dénonçaient des méthodes de recherche “non éthiques” lors d’une étude qui avait été réalisée sur douze enfants seulement.”L’article était en fait un trucage élaboré”, a affirmé mercredi le British Medical Journal, évoquant “de difficiles leçons à tirer pour beaucoup de monde de cette saga très regrettable”. Des accusations qu’Andrew Wakefield a formellement démenti, lors d’un entretien diffusé par CNN.

Lovewells Logic Are we heading for the death of email

first_imgHappy New Year!Earlier this week, I read an interesting article exploring whether 2016 will finally see the end of the office email.The idea of banning email for work has been floating around for a few years now, but several organisations have now begun to bite the bullet and move to alternative forms of communication.I have to admit the idea is certainly appealing (not least when I returned from holiday at the end of last year to find close to 2,000 emails waiting for me in my inbox!)As technology means employees are increasingly always switched on, the temptation to check for email or read messages as soon as they ping into their inbox can adversely impact productivity. We all know the theory about only checking email at designated times during the day, but, in practice, how many of us actually achieve this?But what would the demise of email as we know it mean for workplace communications strategies? There is no denying that email is a quick and easy way of sending messages to a mass audience with the minimum of effort.But in this era of information overload and ‘death by email’, how many truly engage with email messages as intended by the sender? Are there more effective ways of ensuring employees sit up and take notice? Is it time for employers to consider other communication methods, such as Whatsapp or other messenger apps or online channels?Or should employers be considering quirkier methods altogether as a means of grabbing employees’ attention, even if it’s only in the first instance before returning to more traditional methods to communicate the details?On days when my inbox runs away from me, the idea of not having to deal with email is certainly tempting. Yet given how entrenched it has become, not only in the business world but also in everyday life, for alternatives to become the norm, a significant shift in culture and mindset may be needed.Debbie Lovewell-Tuck Editor Tweet: @DebbieLovewelllast_img read more

Halloween Horror Nights Returns to Universal Orlando

first_imgI had not heard much about Dead Waters before attending this year’s event, but once I spoke with the creators; I was told it was A MUST. You first approach a full-size riverboat that is run down and half sunken in the swamps of the bayu. Alligators infest the waters around the boat as lightning crashes in the night sky. Once inside you can really feel the hot muggy swamps the boat has been sitting in all these years. This is the home of the infamous Voodoo Queen. She is all about sacrifices, and you are next on her list. Since this house is a half sunken ship, the floors in areas are sideways and really mess with your equilibrium. This helps push you a tad closer to the creatures that lurk within. The attention to detail was breathtaking in this house and I loved that most of the lighting is just flickering candles. I’d easily put Dead Waters in my top three houses of the event! House Rating: 4½There you have it kiddies! My review of all the houses of fright this year at Halloween Horror Nights 27. Now also keep in mind that the scare zones are themed as well, and one of them is based on one of my favorite horror films of all time. Trick r’ Treat! I’ve always loved what Universal has done with their Central Park area by hanging flicking jack o’lanterns throughout the park’s trees. But to combine this with the music of Douglas Pipes and the iconic characters from the mind of Michael Dougherty was the smartest move the theme park could have ever done. Front porches line the streets as trick or treaters from the film haunt the neighborhood. I know there are four other scare zones (Festival of the Deadliest, INVASION! Altars of Horror and The Purge) But Trick r’ Treat blows them away! The event runs from now until November 4th on select nights and there is a slew of different ticket packages you can choose from. I was invited out to cover this year’s event with a slew of other members of the press as we tackled all nine houses, all five scare zones and checked out the farewell tour of the parks longest running pop culture laugh riot, Bill & Ted’s Excellent Halloween Adventure. I’ve been going to Halloween Horror Nights since 1991 (back then it was called Fright Nights) when the park had one haunted house and a random mix of monsters in the streets. Since then I have seen the event grow into a completely different monstrous beast. Below I have listed out all nine haunted houses and have graded them by how terrifying they are. Now keep in mind, every attendee’s walkthrough may be different. Sometimes an effect may go off after you have walked by it, or a cast change may happen as you walk through a room. Universal usually stays pretty tight when it comes to these kind of occurrences, but it happens. This is simply my personal take on the haunted houses. But don’t fret! I tagged along with a friend who is terrified of all things spooky, so she was a great fear gauge. I consider myself an expert on all things horror… But I’m pretty sure I screamed like a little baby more times than she did so I still find the event scary as hell! Let’s begin. AMERICAN HORROR STORY: VOLUME 2This is Universal Orlando’s second time using the AHS license. Last years house cumulated specific seasons Murder House, Freak Show and Hotel all under one roof. This year the house includes Asylum, Coven, and Roanoke. The FX series has always been hit or miss for me, but walking through these stories was ultimately terrifying! This was one of the more pleasing adaptations. Tortured witches howled in cages, while men wearing severed pig heads tried to chase us down. While transitioning from one season to the next, Cordelia lunged at me screaming after she had just stabbed her own eyes out with a pair of scissors. This easily gave me the ultimate scare! Universal combined the marketing looks of AHS with an actual event that occurred in the show which made for an ultimately trippy experience of terror. House Rating: 4½  HORRORS OF BLUMHOUSE I hope you all are not over SAW yet? After seven films and a new one on the way this October, James Wan’s classic comes to life including traps from each of the film series. I will admit, this was the one I felt I would not care about at all. But it actually was a lot of fun! In the settings that you are provided, SAW looks great! There are interactive elements to this house that I have never seen done before, which proves Universal is always trying to reinvent their frights. There is even a trap from the newest entry in the series at the very end. Definitely keep an eye out for that. Play the game. I promise you won’t be disappointed. House Rating: 3½THE FALLEN Remember when I said earlier there is a severe lack of farmsteads and pumpkin patches in Orlando? Well, this house transports you to a gruesome decaying farm during the great depression era. You walk past dilapidated scarecrows not knowing which ones are props and which one is alive! Once in the farmstead, the second floor has all but collapsed. Maybe this was planned? Or maybe this was left after Hurricane Irma? It was tough to tell the difference. Once through the farm, it looks as if humans and pigs have somehow mended themselves together and they’re not pleased with your arrival. I won’t spoil the last room, but it messes with you as you almost get lost trying to find your way out. House Rating: 4    ASH VS. EVIL DEADEasily one of the BEST shows on television for horror fans has come to life at Universal Orlando. Years ago there was a theater haunted house that took you into different films, and one of those films was The Army of Darkness (specifically the well scene). This was the first time Ash appeared at the event. Now with the help of STARZ Ashy Slashy is back in the same building coincidentally and ready to party! For fans of the series, this house is top notch. You’ll find the book of the dead coming to life and ready to turn you into a Deadite. You’ll also find Ash’s sidekicks Pablo and Kelly ready to fight off the possessed hordes. Make sure to look out for the Eligos. He definitely got me, and I loved every second of it. As I said before, fans of the series will dig this one a lot. But if you have no idea who Ash or what Evil Dead is, this will be the most confusing and probably unscary house of them all. House Rating: 3½ SAW: THE GAMES OF JIGSAW Of all the haunted houses universal has the privilege of licensing. This is the one that fans have been wanting for years. Just imagine walking down the halls of the overlook hotel. Well, we finally get our chance. But this house wasn’t one that could be pulled off easily. It is based on the Stanley Kubrick film so elements from the film had to be near exact. From the twin sisters stalking the halls, to the iconic Room 237; it’s all here and made to mess with you! Let’s also not forget the elevator full of blood. Yes, it happens and it is spectacular! There is also a fun element to the overlook hotel’s ballroom I will not give away that you just have to see! All the Jack’s here wear iconic Jack Nicholson forehead and hair pieces that really give them the deranged look as opposed to just some guy in a brown jacket. This was the cream of the crop for me and a must for any fans attending the event this year. House Rating: 5 DEAD WATER In this house, you are caught in the crossfire of an eternal war between the light and the dark. This is the vampire-haunted house, and I’m not talking about the seductive kind. These are disgustingly disfigured Nosferatu looking creatures of the night who have taken up shop in what looks to be a demonic church. As you walk past the hot coals and bodies stabbed through with pikes, you’ll witness horrors beyond your wildest dreams. Misdirection is key in this house and that is what these beasts want. Since this house is inside a soundstage, the creatures of the night fly! From overhead, to right in your face. This is easily one of the coolest effects at the event and the house itself comes together great. Beyond that, the house did feel a bit short as the soundstage shares itself with another house. House rating: 3THE SHINING From the production company that brought you Sinister, Insidious and The Purge films, Universal combines these three franchises into one pretty interesting house. This one sadly fell a tad flat for me. The outside facade captures the iconic Blumhouse opening logo perfectly, which makes your mind race with anticipation for what is to come. But this house was not very large. Especially when trying to cram all three films together. Just as you are getting into one setting, you are then thrust into another. The Purge is also a scare zone this year which makes you feel like this mediocre film series is being crammed down your throat at the event. This part of the house should have been replaced with a different Blumhouse film with a completely different style compared to the other two. My vote would have been for Lords of Salem or The House That Dreaded Sundown. Get Out would have also been great, but I’m sure that would have been too much of a hot-button topic for Universal to work with. House Rating: 2 SCARECROW: THE REAPING In sunny Orlando Florida, it can be quite difficult trying to capture that special Halloween feeling. The fall weather does not peak its head out until mid-November (if lucky), and there is a severe lack of pumpkin patch hayrides. Luckily for “The City Beautiful,” it is the theme park capital of America, and we do Halloween a bit differently here. We embrace the frightening side of All Hallows ‘Eve with a special event called Halloween Horror Nights! Chainsaws, werewolves, specters and all the horrors that accompany my favorite time of the year are all brought to life by the film studio that started it all back in the early 1920’s; Universal Studios. When it comes to scaring the tighty whities off you, the art & design team at Universal Orlando Resorts are the professionals. This is the event’s twenty-seventh year in a row throwing the ultimate Halloween party for horror fans! With each passing year, the-the park annually outdoes itself by breaking out all the best tricks & treats in their arsenal. For this year’s event, a handful of major properties from film and television were acquired that instantly transport you into your darkest fears. Along with our favorite horror franchises, Universal also cooks up their own original stories brought to life in some of the most breathtaking haunted houses you have ever seen. The streets are filled with maniacs & madmen stationed deep within their own specific zones ready to attack without second thought. Truly nowhere is safe from frights once you enter through the iconic Universal archway. Last but not least, this was the final year for Bill & Ted’s Halloween Adventure. This is a show full of comedy that spoofs on the current years “pop culture hits.” The live show takes place in the Fear Factor venue where the show has access to an enormous lighting rig, pyrotechnics and the most uncomfortable benches you could ever imagine sitting on. As cute and hilarious as Bill & Ted are, they are a bit outdated for today’s youth (come on man, where’s my third installment guys!?) There are jokes every year that cater to the locals that poke fun at Disney and the surrounding area. But for folks out of town, these are all a bit too niche for America’s number one haunt destination. With this being the last year for the show, folks are already predicting what is next. This is the End took over the B&T show in Hollywood which tried out the same pop culture gags. I guess only time will tell for now.Sadly, the second show Academy of Villains: Afterlife was not up and running on media night. Though honestly, I was completely alright with that seeing as how it’s right next to Trick r’ Treat, and it helped me suspend my disbelief for just a little bit longer in this years number one scare zone.All in all, Halloween Horror Nights 27 was an absolute treat this year, and our R.I.P. tour guides were some of the best I’ve ever worked with. You can absolutely see the love and hard labor that the entertainment department puts into this event all year long, and it passes with orange and black colors! I want to thank Universal Orlando again for having us for this event, and I look forward to the horrors that await next year. I’ve already heard the wheels are in motion after all.Make sure to check out the tv spot directed by Eli Roth below.

5 Series From Marvel NOW You Should Be Reading

first_imgStay on target ‘Avengers: Endgame’ Director Explains Thanos’ Faceoff With Captain America‘Marvels’ Expands Marvel’s Podcast Universe While DC Comics has recently been going through their Rebirth initiative, meant to take the DC Universe back to its roots, with legacy characters and renumbering, Marvel seems to be going a different route. Adopting a system of short creative runs with a new #1 fairly often, it almost resembles a TV season in format than it does the superhero comics of years past. Their branding for this, since 2012, has been Marvel NOW! Here, we take a look at five of the best series that the line is currently publishing.Black WidowComing hot on the heels of their Eisner award-winning, critically acclaimed run on Daredevil, writer Mark Waid and writer/artist Chris Samnee have taken over Natasha Romanoff, aka the Black Widow. A perfect spy thriller, the series really stands as something special due to Chis Samnee’s art with colors by Matt Wilson. A true marriage of writing and visual art, Samnee understands exactly how the eye follows a comic page, especially for action. Be it in a dark room or in the middle of the sky, Samnee can do anything, following characters well and never losing the reader’s attention. It takes a very bare bones approach to the character, using only what a reader may know from the movies, and builds from there. It is the kind of comic that makes you want it as a movie so bad, if only because of how well it approaches Natasha as a character. Black Widow Volume 1 is available for download now or in print.Moon KnightMoon Knight is written by Jeff Lemire and drawn by Greg Smallwood as well as an assortment of other artists. The need for multiple artists arises from the story diving into the most fractured elements of Moon Knight’s psychology, starting off with him in a mental institution. Different artists are used to portraying different personalities or how they view the world, giving this book a very distinct voice. While Lemire’s team books have been lackluster, Moon Knight feels more in line with his creator-owned work like Sweet Tooth or the Under Water Welder. Moon Knight is available for download now. Volume 1 will be out in print this Wednesday (11/30).The Amazing Spider-Man: Renew Your VowsSet in an alternate universe where the marriage of Peter Parker and Mary Jane stayed intact, and where they went on to have a daughter, The Amazing Spider-Man: Renew Your Vows is one of the best new series of the year and without a doubt the best Spider-Man story in a long time. Fun, cute, full of heart and warmth, this series follows the Spider-Family as they are forced to deal with new villains on top of the struggles of two parents trying to raise a daughter. Matters get more complicated when Peter and Mary Jane realize that their daughter has inherited her father’s powers. Renew Your Vows is a must read for fans of the characters, or for anyone looking to get into superhero comic books. Available now to download from Comixology or in print.Ultimates 2Al Ewing is an underappreciated gem at Marvel Comics. Consistently getting put on team books or series that are not considered “flagship” makes it feel as if Ewing does not get enough credit as a writer. Every book he has written in the past few years for Marvel has been a blast, and Ultimates is no exception. Currently, on its second “season,” called Ultimates 2, Ewing has taken a team of cosmic superheroes and geniuses and turned it into one of the most insane epics of the Marvel Universe. The first season had Ewing paired with artist Kenneth Rocafort, and the current volume features artist Travel Foreman, both of whom have very distinct styles that make Ultimates feel unlike anything else on the shelf. The first issue is available for download or in print now.ChampionsWriter Mark Waid has a long resume in the comic book industry, but some of his best work can be found in his Impulse series for DC Comics back in the 1990’s. Capturing the idealistic, fun personality of a teenager can be a tough act to balance, but he did it well. He does it again on Champions for Marvel, with artist Humberto Ramos. Ramos’ style is as fun and energetic as one can get without seeming like it isn’t serious. A team of legacy heroes and diverse teenagers, Champions feels like a mission statement for the current era of Marvel Comics. Colorful, fresh and exciting, and filled with a sense of optimism, Champions is exactly the kind of superhero comic that the world needs right now. Issue #1 is out now and can be downloaded here or found in print here.last_img read more

Investigating the dynamics of nanoparticle formation from a precursor at atomic resolution

first_imgFor TEM observation, K2PtCl4 was first dissolved in deionized water in preparation to image its crystal structure. In the bright field TEM image, the crystallite was 50 nm x 60 nm in size. Gao et al. weakened the electron beam dose to the angstrom scale for less than 1 e/A2∙s to limit beam-induced sample reduction during the process of imaging. The scientists conducted high-resolution electron microscopy (HREM) at 300,000 x magnification to obtain 64 images from the same area. By averaging the images, the atomic columns were clearly resolved in the study. The high-resolution TEM image showed periodic lattice squares with an atom (yellow) surrounding those without bright atomic contrast (blue) in the center. Gao et al. compared the atomic resolution images with the existing atomic structure of K2PtCl4 to identify each individual element. The scientists identified the atoms in the corners as potassium (K), atoms in the middle of the edges of the squares as chlorine (Cl) and those in the center of the square in yellow as platinum (Pt). When Gao et al. increased the electron beam dose to 30 e/A2∙s, the lattice from K2PtCl4, which was originally viewed across the entire area developed into individual Pt clusters. In time, the nanoclusters grew more pronounced under the microscope. Low-dose atomic resolution imaging of K2PtCl4.

Credit: Science Advances, doi: 10.1126/sciadv.aau9590. In a recent study, now published in Science Advances, interdisciplinary materials scientists Wenpei Gao and co-workers in the USA and China, studied the reaction kinetics of a solid-state platinum (Pt) precursor compound. In the study, they used an aberration-corrected transmission electron microscope (TEM) combined with low-dose electrons and in situ imaging. The scientists imaged the beam-sensitive Pt precursor; potassium tetrachloroplatinate (II) (K2PtCl4), at the atomic resolution to determine the individual atoms (K, Pt and Cl) involved in the synthesis of platinum nanoclusters. Gao et al. captured the material’s transformation to Pt nanoclusters in real time to show three-stage reaction kinetics, including (1) breaking of the ionic bond, (2) formation of PtCl2 and (3) reduction of the divalent Pt to Pt metal nanoclusters. In the new method, the scientists combined techniques to understand the transformation of chemicals at the atomic scale in real time without damaging the substrates and provided a new platform to study reaction kinetics. Gao et al. captured, identified and revealed the dynamics at different stages of decomposition, reduction and nucleation of the material. The work allowed them to understand the transformation kinetics of platinum from precursor to nanocluster as a promising avenue to study atomic-scale reaction dynamics.

Credit: Science Advances, doi: 10.1126/sciadv.aau9590 Then PtCl42- decomposed into PtCl2 and Cl-, a reaction which had not previously been reported in experimental studies. Gao et al. revealed this process using FFT of the high resolution image under a low electron dose and high acquisition efficiency. On removal of the K species from the precursor, the lattice became unstable and compounds including PtCl2, KCl and Cl2 could move freely. When PtCl2 was reduced in to Pt, the molecules of Cl2 transitioned into the gas phase for removal from the TEM column. The zerovalent Pt species formed small nuclei or migrated and grew into large Pt nanoparticles.In this way, the scientists elegantly demonstrated the reduction kinetics in the study and illustrated the concept using atomic models. The observed findings of nucleation and reduction of Pt agreed with that of previously calculated free energy in the chemical reaction. This method can be applied to study additional material transformations in depth. The results will benefit the applications of nanostructures in nanophysics for new materials development, new energy processes in environmental remediation and in nanomedicine.

Nanocluster nucleation is a key process of growth kinetics in the solid state of materials synthesis. Manipulating the kinetics has allowed the synthesis of a group of nanoparticles shaped as nanorods, nanocubes, octahedra, octopod-shaped nanoparticles, icosahedra and other surface features. center_img , Angewandte Chemie International Edition Scientists develop method for observing nanocrystal formation at atomic resolution They then observed further formation of the Pt nanoclusters across extended time periods under low-dose imaging conditions. The scientists selected a sub-area of the sequential images and applied a fast Fourier transform (FFT) to discern the structure and the constituents. Gao et al. were able to obtain a time series of FFT patterns in the K2PtCl4 lattice, which also reflected the radial distribution function (RDF) (to find adjacent particles). The scientists then investigated the additional surface orientation of atoms in the material, aside from the Pt nanoclusters, to understand the location of K and Cl species. In the work, they used a series of imaging and analytical methods of materials science, starting with high-angle annular dark-field (HAADF) scanning transmission electron microscopy (STEM) and the 2-D energy-dispersive spectra (EDS) map to characterize the material. The results showed the signals from K and Cl in the background as evenly distributed across the area. When the scientists used electron energy loss spectroscopy (EELS) they further observed the existence of K and Cl from KCl, after the formation of Pt nanoparticles. Gao et al. gathered sufficient information from the reaction dynamics captured in real space via spectroscopy and characterization techniques in materials science. They proposed a microscopic process of reduction kinetics for K2PtCl4. Accordingly, the precursor K2PtCl4 first decomposed in to K+ and PtCl42- by breaking the weak ionic bond.

While nucleation is the initial step in materials synthesis, it is difficult to control nucleation kinetics without understanding how atoms interact. Platinum nanoparticles are usually synthesized in a liquid-phase reaction with C-H or Cl- as a precursor. During growth in such a system, the precursor is reduced by the reducing agent to form metal monomers with atomic arrangements based on metal-metal interactions. However, a microscopic mechanism that details the intermediate reaction steps is yet unavailable. As an alternative to materials synthesis in the liquid phase, nanostructures can also be grown in the solid phase. Studying the reduction process in the solid state can decipher materials transformation for fine control of materials synthesis. Understanding the kinetics of materials transformation from precursors to nanostructures at the atomic scale based on ionic bond breaking is therefore of considerable significance. The scientists opted to study the nucleation process in the solid phase without the liquid environment using characterization tools of X-ray nanodiffraction and TEM, which offered ultra-high resolution. The method resolved the evolving structures in real and reciprocal space, although the sensitivity of most chemical precursors to the electron beam due to photo illumination had previously made it nearly impossible to observe the initial atomic structure of the precursor. Explore further A key to materials synthesis is the ability to control the process of reduction kinetics and nucleation (phase transition) in materials. Understanding the reduction dynamics during the initial stage of material synthesis is limited due to the difficulty of investigating chemical reactions at the atomic scale. This is mainly because the chemical precursors used to synthesize materials can degrade when exposed to electron beams that are typically used to image compounds at atomic resolution.
