The SPectrometer for Ice Nuclei (SPIN): an instrument to investigate ice nucleation

first_imgThe SPectrometer for Ice Nuclei (SPIN) is a commercially available ice nucleating particle (INP) counter manufactured by Droplet Measurement Technologies in Boulder, CO. The SPIN is a continuous flow diffusion chamber with parallel plate geometry based on the Zurich Ice Nucleation Chamber and the Portable Ice Nucleation Chamber. This study presents a standard description for using the SPIN instrument and also highlights methods to analyze measurements in more advanced ways. It characterizes and describes the behavior of the SPIN chamber, reports data from laboratory measurements, and quantifies uncertainties associated with the measurements. Experiments with ammonium sulfate are used to investigate homogeneous freezing of deliquesced haze droplets and droplet breakthrough. Experiments with kaolinite, NX illite, and silver iodide are used to investigate heterogeneous ice nucleation. SPIN nucleation results are compared to those from the literature. A machine learning approach for analyzing depolarization data from the SPIN optical particle counter is also presented (as an advanced use). Overall, we report that the SPIN is able to reproduce previous INP counter measurements.last_img read more

SA, European scientists ‘in synch’

first_img23 May 2013 South Africa’s National Research Foundation (NRF) has signed an agreement with the European Synchrotron Radiation Facility (ESRF) in Grenoble, France to promote scientific collaboration and knowledge sharing. The NRF has become a full international scientific partner to the ESRF through the agreement, which will facilitate the access of South African scientists to the ESRF and of European scientists to South Africa’s research opportunities and expertise. “This is a remarkable achievement and it recognises the excellence of our local scientists as well as the global research opportunities that can be accessed from South Africa,” NRF chief executive officer, Albert van Jaarsveld, said in a statement on Wednesday. South Africa is the first African country to become a member of the ESRF. ‘Strong scientific collaboration’ Scientists from South African research organisations and the ESRF have enjoyed strong collaborations since the early 1990s. Several of the country’s industries have also conducted research at the ESRF – Sasol, for example, has experts based at the facility. Local scientists’ achievements using synchrotrons have also been featured in leading international journals such as Nature and Science. “A synchrotron is a brilliant source of near laser quality ‘light’, which covers the spectrum from the infra-red to the hard X-ray regime in a continuous manner,” the NRF said. It allows for research in numerous fields, including nanoscience, medicine, the biosciences, environmental sciences and geosciences. Synchrotrons have also driven innovation in palaeontology, enabling fossils to be studied more closely, even if they are still partially enclosed in rock. “South African paleontology recently made international headlines when the brain of an early human ancestor Australopithecus sediba specimen nicknamed Karabo was visualised and studied in the fossilised skull buried in stone,” the NRF said. This was a world-first for syncrhotron technology. “For some years now, we have seen a new growth trajectory in science in South Africa and the agreement between the NRF and ESRF serves to further build human capital and research capacity for sustainable growth and development in South Africa,” said the Science and Technology Department’s Thomas Auf der Heyde.

Zelda Goes To The Symphony

first_imgTags:#geek culture#Nintendo#video games Both the music and multimedia presentation are preapproved by Nintendo, and Jason spent a great deal of effort to maintain the integrity of legendary Nintendo game composer Koji Kondo’s work. “That’s a heavy responsibility and I take that very seriously,” he said.Seriously indeed. Before the show, Jason showed me around backstage, where members of the 66-piece orchestra (featuring not one but two harpists because, well, it’s Zelda) and 24-voice choir were preparing for the two-act performance featuring nine pieces (and, spoiler alert: several encores) from the original Zelda themes. The orchestral adaptations were arranged by composer Chad Seiter, who’s no stranger to geek sounds with a résumé that includes Star Trek Into Darkness, Fringe, and Lost.In fact, there was no shortage of geekery in Davies Symphony Hall: the Skywalker Symphony Orchestra was the performing group on stage that night, the conductor wielded a Wind Waker baton, and the auditorium was full of fans dressed in cosplay. It felt less like going to a classical performance and more like a mini, Zelda-exclusive Comic-Con.Fans dressed as Link and Zelda (not at the symphony, though)“Once you walk through the door, you have the feeling that you’re at a video game concert. You see people dressed up… from the green tunics to Ganon costumes to Link costumes. It’s quite an atmosphere and it’s something that I strongly encourage,” Jason said.The fandom is, perhaps, the most innovative thing about Symphony of the Goddesses. The show breathes new life into the classical format, introducing the grandeur of a live orchestra to a different audience. The crowd cheered through the performance, a reminder that these were not conventional golf-clapping concertgoers. Attendees of all ages were present that night, from young symphony first-timers to grown-up geek couples — there was even a proposal during intermission!More stories from PopSugar Tech:The Californication of Mac OS X: What Could Come After MavericksHow Superman ShavesMicrosoft Office Finally Debuts To iPhone UsersInappropriate and Sexist Vintage Comic Book MomentsTumblr of the Day: Jony Ive Redesigns ThingsThe Zelda Symphony season is just kicking off touring the rest of the country through October, including tonight’s performance at the Greek Theatre in LA.

The audience is in cosplay and the music of The Legend of Zelda begins, triggering memories of swashbuckling through Hyrule.But it’s nothing like the 246-megabit soundtrack I grew up with. No, this is Symphony of the Goddesses, a reimagining of the beloved Nintendo franchise, filling San Francisco’s Davies Symphony Hall with heroic sounds inspired by the game, while scenes from a selection of Zelda titles are projected above the musicians. The concert, now touring the US and Canada, is a must-see music experience that’s not just for gamers.After The Legend of Zelda: A Link Between Worlds‘ recent release on Nintendo 3DS, it seems fitting to relive the best musical moments of the 27-year-old franchise with the grandeur of the symphony.Even if you’ve never channeled the justice-seeking, princess-avenging, Ganon-destroying hero, Link, the spectacle of this performance and score will move you. But executive producer Jason Michael Paul wants to reassure Nintendo fans that Symphony of the Goddesses is a completely authentic Zelda experience. 5 Outdoor Activities for Beating Office Burnout 9 Books That Make Perfect Gifts for Industry Ex…last_img read more

Watch how Croatia players celebrated on board their flight back home

first_imgCroatia achieved their best ever finish in a World Cup and they were thrown a grand party on their arrival in Zagreb on Monday.But, that was not all. The players had a party of their own and enjoyed on their way back home as well. Vedran Corluka uploaded a short video on Instagram, where he, Mateo Kovacic and Marcelo Brozovic can be seen singing a song and enjoying a few drinks inside the aircraft.The trio didn’t start each and every game for the Croates but they played an important role in Croatia’s run to the final. Kovacic and Brozovic especially were vital cogs in Croatia’s midfield that was ably carried by Luka Modric, who also won the Golden Ball award in this year’s tournament.Speaking about their campaign in Russia, Modric said: “Our dream came true.”2018 FIFA WORLD CUP: FULL COVERAGEFans gathered in the streets to welcome their heroes, who bettered Croatia’s ‘golden generation’, who lost to France in the semi-final in 1998 in France. Till date, that was the best Croatian team according to the people of Croatia but Luka Modric’s men have done one better and as they returned home, they were treated like superstars in the streets of Zagreb.A heroes’ welcome. #BeProud #WorldCup | CFF (@HNS_CFF) July 16, 2018A nation united.

Modric’s side won all three group matches as they defeated Nigeria, Argentina and Iceland to finish at the top of their group.In the knockouts, the Croatians registered three consecutive come-from-behind victories as they reached their first World Cup final.Modric was the standout of the team and can still earn the title of world player of the year, breaking the stranglehold of Cristiano Ronaldo and Lionel Messi.Croatia almost failed to qualify for the tournament in Russia, needing a 2-0 victory at Ukraine in their last group match to earn second spot that sent them into a playoff against Greece. Croatia reached their first ever World Cup final in this year’s tournament in Russia (@HNS_CFF Photo)It was the start of Zlatko Dalic’s term at the helm and the coach managed to guide them to Russia where they displayed some of the finest soccer on show.And after the brilliant show in Russia, expectations will be high and fans would hope that this team can do wonders and finally win a major tournament in the coming years and make their nation prouder.last_img read more

Valerie Plantes election signals a move away from oldstyle politics analyst

first_imgMONTREAL – Valerie Plante’s election as Montreal mayor sends a clear message that people are tired of old-style politics, according to one political scientist.Concordia University’s Daniel Salee described former mayor Denis Coderre as “a sort of grumpy old bear” who thought he knew what was best for Montreal.“Coderre is an old politician in a sense that his approach is one that’s been favoured by the older generation of politicians, which is essentially smear campaigns and attacking or essentially trying to delegitimize the positions of their adversaries,” Salee said in an interview Monday.‘I think we’ve reached the point where people are not interested in these types of old tactics where politics appears to be a competition, a fight to the finish.”Enter Plante who, with her constant smile, appeared to connect with Montrealers over the last few months on her way to becoming the city’s first female mayor.“You don’t have to be a professional politician to do this job and that’s the message people are sending, that you are going to have to be more attentive to what the people are saying and you’re going to have to listen to what they have to say,” Salee said.The political analyst added that if Coderre had been re-elected, what Montrealers would have seen in the next five years is more of a man who thinks he owns the city.“He was already going in that direction,” Salee added.While Montreal’s economy boomed during his mandate, Coderre was often branded by opponents as an arrogant leader who made hasty decisions with little consultation.About a week before the election, he addressed head-on the arrogance allegations.“Listen, to be arrogant is to be determined,” Coderre said, adding it’s not easy running a city with a $5-billion budget and 28,000 employees. “Sometimes you have to have somebody who can take the heat and can make a difference.”Plante’s victory is considered historic in a city where municipal politics has long been male-dominated.“It’s changed a little over the past few decades, but it’s changing slowly,” Salee said.Youssef Amane, Plante’s press secretary, says the new mayor’s trademark smile is not fake, adding she’s like that all the time.“So definitely what you see is what you get,” he said in an interview Monday. “It’s genuine.”Amane said Plante, 43, actually began a pre-election campaign back in August and has been on the hustings non-stop for three months.“Her level of energy was just flabbergasting,” he said, adding she was always willing to listen to what people had to say.“Her sense of humour and her ability to find positives in every situation is really helpful in terms of dealing with the crazy life on the campaign trail.”Amane admitted Plante raises the bar and expects everyone to come prepared for meetings.“I’ve been working with her for many months now and I’ve never seen her lose her temper,” he said.Plante, who was born in Rouyn-Noranda in northwestern Quebec, spent a year as a teenager in North Bay, Ont., to learn English.She moved to Montreal at the age of 19 and attended university where she received degrees in anthropology and museology.She then worked for a number of non-profit organizations.Plante entered municipal politics in 2013 when she won a council seat in a contest that pitted her against former provincial cabinet minister Louise Harel.In 2016, she was elected leader of the left-leaning party Projet Montreal.The mother of two began the mayoral race as a relative unknown but opinion polls showed her steadily gaining on Coderre as the campaign continued.Her signature campaign promise was the new subway line that would link the city’s densely populated northeast to downtown.last_img read more

Sinking Fund getting too much Police getting too little says Five Cays

Hon. Sean Astwood: “What I am understanding is that the Police Force is saying to somebody, whether it is the government or the CFO, that they need these set of equipment in order to properly conduct their business in terms of the safe keeping of this country and someone is deciding what they can get and what they cannot get.”During the recent Appropriations Committee meeting it was exposed that some equipment is denied by the Government during consideration of the Royal Turks and Caicos Police budget.Deputy Commissioner Rodney Adams: “Madame Chair and Members that is correct. I can certainly speak to some issues where some requests have been made and was not approved as it relates to a number of pieces of equipment that was needed for the department.”Permanent Secretary of Finance, Athenee Harvey aimed to explain the dynamics of decisions. Athenee Harvey, PS Finance: “The Ministry of Finance, the Department heads, the accounting officers I lift my hat to them because there are a lot of difficult decisions – even the leaders of the Opposition and Members of the House of Assembly. It is very difficult to actually have to decide what you have to forego for a temporary period of time.”Hon Astwood posed another problem, “I thank you for that explanation Madame PS but surely there is someone who is deciding it is more prudent and beneficial to put extra money above and beyond what is budgeted for into the Sinking Fund than providing the equipment what that they needed; someone is making that decision.”It was recommended by chairperson of the Appropriations Committee, Hon Ruth Blackman that the issue be brought up in a more appropriate forum, namely, the House of Assembly. last_img read more

Sean Dyche admits Burnley are playing with fear

first_imgBurnley are struggling to maintain the heights of last season and are playing with fear, according to manager Sean Dyche.The Clarets are currently in the relegation zone after 14 games and the 2-0 defeat at Crystal Palace condemned them to their fifth defeat in six Premier League games.With games against Liverpool, Tottenham, and Arsenal to come before the festive period, Dyche said hard work and a bit of luck are the only things that can improve the club’s situation.“[Crystal Palace] deserved to win,” he told Sky Sports. “The performance: there was a bit of fear attached to it. The eye of the tiger we had last year – it was a collective unit – has softened quite obviously – and that can happen with tough results.Burnley FC v Manchester City - Premier LeagueMatch Preview: Burnley vs Liverpool Boro Tanchev – August 30, 2019 Premier League leaders Liverpool travel to Burnley for the Matchday 4 of the 2019-20 Premier League campaign.“There’s a lot of demand on this season, a different kind of demand that is new to the players and new to the club as well.“I think that that affects the way a group works sometimes, and I think they’ve found a challenge within that. So each game has that bit of trepidation to it and instead of that professional enjoyment that you want from your players, it becomes huff and puff, ‘just get through it’ and that mentality.“I’ve been through it myself down my career as a player and as a manager as well. To get that eye of the tiger back, it usually – not always – comes from hard work. The reason I say not always is that now and again you get it from a lucky one.“It’s strange football, you nick a lucky win and all of a sudden it looks different, but you don’t want to rely on them. You want to rely on the good work that the players can do to turn things around.”last_img read more
