Do I dial 911 if grandma falls or should I call my mother atwork? What do I do if there’s another hurricane and our powergoes out? What will happen if a world crisis happens close tohome? Children of all ages have questions like these. With the help ofthe Nova Scotia Emergency Measures Organization (EMO) and theCanadian Red Cross, educators and parents throughout Nova Scotiacan help find the answers they need. Teachers, families and children may also Prepare Now! and LearnHow! during this week, Emergency Preparedness Week (May 1 to May7). The 911 Activity Pack, available on the province’s EMO website,is used to help teach younger children about the 911 service andhow they can properly identify an emergency. Nova Scotia’s 911 service is one of EMO’s key programs. Thisprovincewide service is the first of its kind in Canada. “Having guides like the 911 Activity Pack in the classroom and athome is an important step toward improving emergency preparednessamong all Nova Scotians,” said Mike Myette, manager of theprovince’s 911 service. Activities like field trips and role-playing exercises givestudents the opportunity to learn about emergency preparedness ina fun and interactive way. The activities in the 911 ActivityPack are also designed to help reassure students that emergencyhelp is available when they need it, even if a parent isn’tnearby. The pack also contains simple household chores and activitiesthat parents can complete with their youngsters at home. Theactivities– which include things like preparing a familyemergency kit and making a list of emergency phone numbers andaddresses — are only some of the many ways parents can helptheir children prepare for the unexpected. “The 911 Activity Pack fits in well with the curriculum andlearning objectives for my students and can be easily taught byparents as well,” said Mary Osborne, who teaches grades two andthree at Sir Charles Tupper Elementary School in Halifax. “Younever know when a child will have to be the one to make a 911call and this pack is very helpful in teaching young people whatthey need to know in order to feel comfortable making that call.”The Canadian Red Cross is also doing its part to encourageemergency preparedness among students, teachers, and families. Children between the ages of five and 16, for example, canbenefit from the Expect the Unexpected and the Facing Fearprograms. Available on the Canadian Red Cross website, theseprograms are filled with lesson plans, videos and other toolsthat help students prepare for and cope with emergencies liketerrorist attacks and natural disasters. The Expect the Unexpected program focuses on helping youths andfamilies learn disaster preparedness techniques and deal withunexpected natural disasters, like Hurricane Juan, which struckNova Scotia on Sept. 29, 2003 as one of the most powerful anddamaging storms in Canada. But children not only need to be prepared for an emergency, theyneed to know how to cope with one. The Facing Fear program, themost recent emergency preparedness program offered by theCanadian Red Cross, helps young people deal with the aftermath ofa tragic event. It encourages teachers to talk to their studentsabout managing their feelings. It also deals with the role of themedia and their impact on public opinion, and with internationalhumanitarian law. “Our programs help teach young people how to be prepared foremergencies and how to cope with them as well,” said JoanneLawlor, manager of community development for the Canadian RedCross. “These programs give teachers the opportunity to preparechildren for emergencies, build their confidence in their ownskills and give them the techniques to deal with an emergency.” For more information on the Expect the Unexpected and Facing Fearprograms, see the Canadian Red Cross website at www.redcross.ca .For more information on the 911 Activity Pack and emergencypreparedness, see the province’s EMO website at www.gov.ns.ca/emo. -30- EMERGENCY MEASURES ORGANIZATION–Keeping Young People Safe andPrepared in an Emergency
Darjeeling: The transporters’ associations of Darjeeling have given a clarion call to all drivers to discard the coupon system of the police and not to collect passes to Tiger Hill from Wednesday. They have also threatened to launch an agitation if the system is not rolled back by Saturday.Incidentally, the Darjeeling police have implemented a number of changes to the traffic system from September 1 to ease the traffic problem that the town faces, especially during tourist season. Also Read – Bengal family worships Muslim girl as Goddess Durga in Kumari Puja”We request all drivers not to collect coupons to Tiger Hill from Wednesday as we do not support this system. The system has to be rolled back in the next two days. The administration and police have assured us that this was a trial and that a review meeting would be called soon. If the review meeting is not called then on Saturday we will hold a meeting with the stakeholders and announce our agitation programmes. We could even drive up to Tiger Hill without coupons and if they turn us back we might leave our vehicles there and return,” threatened S N Pradhan, president, Himalayan Transport Coordination Committee. Also Read – Bengal civic volunteer dies in road mishap on national highwayThe Darjeeling police have capped the number of vehicles to the world famous sunrise point Tiger Hill at 300 from September 1. Coupons are issued the previous day from the traffic police office in Darjeeling town to visit Tiger Hill. A drop gate has been put up at Jorebungalow on the access road to Tiger Hill, where police conduct checks. Vehicles without valid coupons are not allowed to Tiger Hill. Recently, a team representing the travel and tourism industries of this region met state Tourism minister Gautam Deb in Siliguri and handed him a memorandum appealing for a rollback. The minister had subsequently assured them of a review meeting. “We had even given a memorandum to the Superintendent of Police. The whole of Darjeeling depends on tourism directly or indirectly. This system is just causing glitches and is not practical. It has to be rolled back immediately,” said Pradeep Lama, spokesperson of the West Bengal Tourism Forum. The travel trade industry representatives claim that with the Forest department allotting space for car parking at Tiger Hill, around 1,000 vehicles can fit without causing a traffic snarl. The police have called for a meeting with the stakeholders on Saturday at 11:30 am in the conference hall of the Police Lines, Dali. “Our system will stay in place. We will not allow any vehicles without valid passes,” stated Dorjee Sherpa, Traffic OC.
Melissa RidgenAPTN NewsIndigenous people have been “let down” by the electoral system and a way to fix it would be having better representation in the province’s legislature, says Steven Fletcher, and independent MLA for the riding of Assiniboia in Manitoba.The Indigenous Representation and Related Amendments Act 2019 is to being introduced Monday.It calls for four Indigenous seats in addition to the 57 seats that exist in the province.“In general terms there would be one seat in the north, one seat in rural southern Manitoba and two seats in Winnipeg (Winnipeg North and Winnipeg South),” the document reads.To pay for the new seats, he says all MLA salaries and expenses should be cut back 7.5 per cent to maintain current spending levels.Support for the act would mean MLAs from the Progressive Conservatives, NDP and Liberals would vote themselves a pay and expense cut.“I am hopeful that the government and the opposition will give this bill their due consideration,” Fletcher said.The Legislative Assembly Act would be amended to allow each individual Indigenous representative to consider themselves a political party.Fletcher said the act was inspired by New Zealand’s electoral system, which guarantees Maori a certain number of seats in parliament.Currently seven out of 120 seats are occupied by Maori politicians.“The idea is that with four seats created for indigenous representation in our legislative body, the system will do better for all Manitobans,” the document says.After being introduced today, it’s on the order sheet to be advanced to second reading.“Assuming it passes a vote on second reading, it will go to Standing Policy Committee where it will undergo scrutiny and be opened to public consultation,” Fletcher said. “If the bill does not go for second reading, the government who votes against it will need to have a really good reason to explain why they won’t allow it to proceed.” Any Manitoban, regardless of their ethnicity, could vote in their constituency or in an Indigenous constituency, but not both says the proposed legislation.Fletcher is a former Member of Parliament and served under Stephen Harper as a cabinet minister as the minister of State (Transport) before switching to provincial politics where he joined the Conservatives.He was removed from caucus after a series of disagreements with leader Brian Pallister and is the leader of the Manitoba Party in the email@example.com
New Delhi: Concern over the suicides of their staff, a department of Delhi Police has written to all districts and units asking them to submit the list of the police personnel who needs medical care and special attention.The city police said that they have taken different measures for the welfare of their staff. Police sources told Millennium Post that a letter was written from the office of the Special Commissioner of Police Welfare and Estate Oversight to all the districts, units including Principal PTC with the subject regarding psychological disorders of police personnel in Delhi Police. Also Read – Odd-Even: CM seeks transport dept’s views on exemption to women, two wheelers, CNG vehicles”It has been noticed that a considerable number of police personnel posted in different districts and units of Delhi Police are facing psychological disorders which restrict them from active police duties as well as developing the tendency of committing suicide,” sources said quoting the letter. Recently two cases of suicides of police personnel have come to notice in which they had been facing some psychological problems. They further added that it is directed that a list of police personnel posted under your control having psychological disorders, who need medical care and special attention, be provided to this office within a week. This has the approval of Special CP/Welfare and Estate Oversight. Also Read – More good air days in Delhi due to Centre’s steps: JavadekarThe data accessed by Millennium Post revealed that in the year 2017 more than 10 suicides were reported whereas last year as many nine police personnel took the extreme step. According to police, they took various initiatives including yoga to ease out the stress of the police personnel. A press statement of city police said that at the grass root level, yoga for the personnel shall not only improve productivity but also keep them mentally and physically fit. In the year 2018, yoga cell of Delhi Police conducted 122 camps in which 2,155 personnel participated. Another major initiative is Sampark Sabha, where senior police officers interact with the different ranks to gather information on field-oriented issues being faced by the lower functionary. By holding Sampark Sabha the grievances of police personnel can be addressed and further action can be initiated. “We also conduct health awareness camps for the police personnel,” police said. In a bid to motivate police personnel, the city police always reward cops for their bravery.
By Kevin KriedemannLondon – Egypt’s prosecutor general has ordered the release of Al Jazeera Arabic journalist Abdullah Elshamy on medical grounds, ending almost a year of imprisonment without charge.A statement from the prosecutor’s office on Monday said Elshamy, who has been on hunger strike since January, would be set free due to “health conditions.” The statement said 13 other people would be freed on the same grounds. Elshamy, born in Egypt but raised in Nigeria, has been on hunger strike for 147 days in protest of his prolonged imprisonment without charge. He was arrested on 14 August 2013 while covering the violent dispersal of a sit-in by supporters of Islamist president Mohamed Morsi, who was overthrown by the army in July.Commenting on the Egyptian prosecutor’s statement that Elshamy will be released, Al Jazeera spokesperson Osama Saeed said, “This is a relief rather than a cause for celebration. Abdullah has been through a terrible ordeal for over ten months. He’ll want to spend time with his family and recuperate. When he’s ready, we look forward to seeing him back in action, doing the vital job of journalism that he so clearly loves.”Al Jazeera English journalists Peter Greste, Baher Mohammed and Mohammed Fahmy are still behind bars, and Al Jazeera continues to call for their freedom. A verdict in their case is due on 23 June 2014.In a final plea from defence lawyers, the court yesterday was reminded that this “trial is not a trial for these defendants alone – but a trial of all journalists.”Fahmy, who was allowed to address the judge before the case was adjourned, also said: “This case is a political case.”Saeed said, “Yesterday was the final summation by the defense. Again the weaknesses of the prosecution case have been exposed. On the balance of arguments, Al Jazeera hopes the judge will take into consideration the facts presented to him and acquit Peter, Baher and Mohammed of any wrong doing. On June 23rd, the entire world will be watching Egypt to see whether they uphold the values of press freedom.”Previous court dates have bizarrely included the prosecution showing footage of Sky News Arabia tourism reports, BBC podcasts, songs by Gotye, photoshopped images of Fahmy, Greste’s family photos, and some of Greste’s award-winning work from East Africa.Calls for the release of the Al Jazeera staff have been made from the White House, the British Foreign and Commonwealth Office and the European Union. Similarly public calls of support for the #FreeAJStaff campaign have been made from prominent media personalities with over 60,000 people supporting the #FreeAJStaff campaign, which has had over 1.2 billion impressions on Twitter. Various media freedom and human rights groups have also issued statements ranging from the Committee to Protect Journalists, the International Press Institute, Amnesty International and The Foreign Correspondents Association of East Africa.
Mr. Deiss met yesterday with Ambassador Hardeep Singh Puri of India, which holds the rotating Council presidency this month, according to a statement issued by the Assembly President’s spokesperson.The ambassador and Mr. Deiss discussed the Council’s upcoming debate on peacekeeping, scheduled for 26 August, as well as current hotspots such as Syria, Libya, Yemen, Sudan and Somalia.The two officials also discussed how to strengthen coordination and interaction between the 193-member Assembly and the 15-member Council.In a separate meeting with Ambassador Lazarous Kapambwe of Zambia, the current President of ECOSOC, and members of ECOSOC’s bureau, Mr. Deiss discussed reform of the 54-member Council so that it can more effectively implement its resolutions.Mr. Kapambwe also briefed Mr. Deiss on ECOSOC’s recent annual substantive session, which wrapped up at the end of last month in Geneva. 12 August 2011General Assembly President Joseph Deiss has met with the heads of the Security Council and the Economic and Social Council (ECOSOC) to discuss increased cooperation, United Nations reform, regional crises and other issues.
SASKATOON — Potash Corp. of Saskatchewan Inc. says it earned $53 million in its latest quarter, down from $81 million a year ago, as it works to close its merger with Agrium Inc.Chief executive Jochen Tilk says the company has obtained regulatory approvals in four jurisdictions with only the U.S. and China remaining.Tilk says the company still expects to close the deal by the end of the year.The company says the profit amounted to six cents per diluted share for the quarter ended Sept. 30 compared with a profit of 10 cents per share a year ago.Sales in the quarter totalled $1.23 billion, up from $1.14 billion.PotashCorp (TSX:POT) and Agrium (TSX:AGU) announced a deal to merge last year.The combined company, to be named Nutrien, will have its official head office in Saskatoon while keeping a corporate office in Agrium’s home city of Calgary.

Sandvik is introducing a new 3-t narrow-vein LHD that, it says, “offers reliability, productivity and increased safety that has not previously been seen in its size class globally.” The new Sandvik LH202 loader is targeted for narrow-vein mining applications with drift widths between 2 and 2.5 m. It has been designed to help reduce dilution and improve flexibility and operator safety when working in narrow-vein operations.The LH202 is full of features to help mines maximize tonnes and minimize extraction costs. It has been engineered to optimize machine width, length and turning radius. Sandvik says the “LH202 can reduce cost per tonne by up to 36% thanks to its reduced operating width and larger capacity compared to other loaders in the same size class.”“Due to its compact size and advanced transmission, Sandvik LH202 is both easy to drive and manoeuvre in confined spaces typical of narrow-vein tunnels”, says Kimmo Ulvelin, Product Line Manager, Narrow Vein & Low Profile loaders at Sandvik Mining and Rock Technology. Ashleigh Braddock, Global Sales and Marketing Support Manager, Product Area Load and Haul at Sandvik Mining and Rock Technology, says an operator compartment located in the loader’s rear frame helps improve operator safety and comfort.“With this safety design, we have moved the operator further away from falling rocks during bucket loading,” Braddock says. “Improved visibility and powerful LED lights help reduce collision risk while ground-level daily maintenance reduces risk of slips, trips and falls. Enhanced ergonomics in the operator compartment keeps the operator more comfortable during the shift, enabling to focus on production”.With sustainable operation in mind, and to enable the use of this LHD in markets with low engine emission requirements, the new loader will be available with either a standard Tier 2 engine or a lower-emission Tier 4 engine in the future.The new LH202 completes a comprehensive offering of Sandvik loaders engineered for narrow-vein operations. These range from the LH201, the smallest loader with a payload of 1 t and capable of operating in drifts as narrow as 1.5 m, up to the Sandvik LH307, with a tramming capacity of 6.7 t in drifts that are greater than 3 m wide.

Facebook Twitter: @NeosKosmos Instagram After a landmark deal in 2014 which created a direct labour agreement with the Australian government to sponsor 20 Greek nationals per annum, Fronditha Care held a recruitment conference in Greece last week.The existing agreement with the Department of Immigration and Border Protection allows Fronditha Care to sponsor people qualified in nursing and aged care, and when a rare opportunity presented itself, CEO George Lekakis told Neos Kosmos the community care organisation took advantage of direct links to hold a conference in the Greek capital. “We took the opportunity to host a seminar in Athens to raise further awareness of the labour agreement provisions that we have and the need to recruit future personal care workers on a 457 visa at Fronditha Care,” he said.“This once-off seminar was hosted by one of our HR officers, Yiannis Androulakis, who was in Greece for personal holiday reasons, but I wanted him to use the opportunity to spread the word and to recruit future employees for our wonderful organisation.”The event, advertised via student recruitment networks, was hailed a success, with large numbers pouring into the Royal Olympic Hotel in Athens, many of whom, he said, have made further enquiries into prospective employment.“A lot of people in the networks now know of the availability of this 457 visa and people are referred appropriately. People make direct contact through us and also look out our website for necessary information and follow the appropriate steps, which are what steps one needs to take in order to qualify for employment, and also the recruitment processes as well.”Along with the conference, Fronditha Care is also appealing to people locally who are keen to work in personal care and can comfortably speak Greek.

DALLAS — Freezing rain and stinging winds slammed the Southwest on Friday and made a strangely blank landscape out of normally sun-drenched North Texas: mostly empty highways covered in a sometimes impassable frost, closed schools and businesses, and millions of residents hunkered down for icy conditions expected to last through the weekend.Earlier this week, many in Texas were basking in spring-like temperatures that hit the 80s. By Thursday, Texas faced the same wintry blast that has slammed much of the U.S., bringing frigid temperatures, ice and snow.The weather forced the cancellation of Sunday’s Dallas Marathon, which was expected to draw 25,000 runners, some of whom had trained for months. A quarter of a million customers in North Texas were left without power, and many businesses told employees to stay home.Rob Yates, 44, of the Dallas suburb of Rowlett, had trained for four months to participate in the half-marathon Sunday — his first time competing at that distance. His wife and three children were going to attend the race to volunteer and cheer him on, he said.Now, “I’ll probably be catching up on some work,” Yates said, laughing.Yates spent Friday at home with his children, who were outside pulling off icicles and wishing more snow had fallen. But Yates, originally from near Manchester, England, said he stayed inside with his wife.
EXCLUSIVE: Charlotte Frost, benefits and wellbeing manager, HR at asset management organisation Schroders will speak about how reward and benefits professionals can engage a worldwide employee base using a global wellbeing strategy at Employee Benefits Connect 2019.The session, titled ‘Creating a workplace culture that fosters employee health and wellbeing’, will form part of the recognition and motivation conference stream on Wednesday 27 February 2019.Frost will discuss the key challenges in preparing and implementing a wellbeing strategy or campaign when the goal is to engage and appeal to employees from different cultures and locations.She said: “One of the biggest challenges that wellbeing programmes have is engaging with organisations globally around wellbeing, and the fact that some topics don’t lend themselves very easily to a consistent message. It can be due to cultural differences, including stigma [and] languages. It’s just being mindful that not everywhere uses the same terminology and positioning.”Frost will also share her own experiences of rolling out wellbeing initiatives in locations such as Asia, Canada, the UK and US, providing real-life examples of approaches that work, pitfalls to avoid and key learnings she has gleaned to date.“I’ve got some good stories to tell, and some real-life examples of what has worked, but [I will also be] honest about what hasn’t worked and how we’ve taken learning from that,” Frost said.For example, Frost plans to discuss a cancer awareness initiative she launched in Asia and the US where differing terminology was a factor. She will also talk about a wellbeing programme she was tasked to roll out in the UK which was created by a Canadian organisation, and why this proved difficult.“Despite having all the best efforts and doing something which is morally the correct thing to do, because [the organisation] didn’t take the time to engage locally and find out what would be suitable for different audiences, the take up or the engagement with the [campaign was] lower. It was a missed opportunity really,” she explained.Frost’s session will emphasise the importance of communications. “[HR professionals] only get one time to get it right,” she noted. “Communication is key, and [organisations should] take the time to get it right up front.”Employee Benefits Connect 2019 will take place on Wednesday 27 February 2019 at the Park Plaza Westminster Bridge, London.Click here for more information or to book your place.
Mediabistro.com owner WebMediaBrands said Monday it has agreed to sell its Internet.com division to vertical media and marketing firm QuinStreet Inc. for $18 million in cash. The sale effectively ends WebMediaBrands’ standing in the online tech trade business sector.WebMediaBrands’ board of directors unanimously approved the transaction and recommended that the company’s shareholders approve it, too. The company said the deal is not subject to a financing condition and is expected to close free of taxes.According to chairman and CEO Alan Meckler, the sale will “significantly improve our balance sheet and at the same time allow us to focus on growing b-to-b communities in the non-tech space.” Meckler and a number of other shareholders—who collectively hold a roughly 40 percent stake in the company—have already agreed to support the deal, the company said. In April, WebMediaBrands, the company formally known as Jupiter Media, folded its two bi-monthly design magazines: Dynamic Graphics+Create and Step Inside Design. The closures effectively marked the company’s exit from traditional print publishing.WebMediaBrands will continue to produce Mediabistro.com, Graphics.com and their related job boards.
Popular on Variety Facebook Watch will launch a slate of new shows boasting interactive features like polls and quizzes to make good on the social platform’s intent to foster a greater sense of community between creators and users.The new features will be employed across content like “Outside Your Bubble,” a new series set to premiere next month from Buzzfeed News that lets contestants guess what their opponents from the other side of the cultural divide are thinking. Other new programs include game shows that let viewers play along across live and on-demand video on Watch.Fidji Simo, VP of product at Facebook, believes interactivity hasn’t advanced much in traditional TV beyond voting for contestants on shows like “American Idol.” “I think this is a mega-trend we’re seeing in this industry, where video doesn’t have to be passive or one way,” she said. “Now that video is happening on mobile devices, where there is input possible from people, you can imagine a whole range of genres for content to be reinvented with audience participation.” The new functionality will be unveiled at Facebook’s first-ever “Creator Day” in Los Angeles where influencers the social giant has been more aggressively courting in recent years will convene to learn new monetization techniques as they attempt to build businesses on the platform. The features will also likely be touted at Vidcon, the annual online video confab taking place in Anaheim, Calif., later this week.Facebook will also be unveiling other new initiatives thi week intended to help influencers including the launch of Brand Collabs Manager, a new program intended to help marketers find the right creators for branded content efforts. Influencer monetization will also be helped by expansion of already launched initiatives to allow creators to implement ad breaks and subscriptions tolls. ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.

The researchers, led by Professors Peter Nordlander and Naomi J. Halas of Rice University in Houston, Texas, and Professor Emily A. Carter of Princeton University, New Jersey, have published their study on the technique to improve catalytic chemistry in a recent issue of Nano Letters.In their method, the researchers used a visible-light laser to illuminate a gold nanoparticle surface (the catalyst surface) at room temperature. The incoming laser light optically excites surface plasmons on the metal surface, and the plasmons then decay into hot electrons. Because of their high energies, the hot electrons extend further away from the nanoparticles than electrons with lower energies do. If another atom or molecule that can accept the electron is nearby, the hot electron can transfer into that acceptor’s electronic states. In these experiments, the researchers adsorbed H2 molecules on the gold nanoparticle surface, a procedure that is commonly performed in heterogeneous catalysis, in which the adsorbed molecules act as reactants. The researchers found, as the main result of their study, that some of the hot electrons could transfer into the closed shells of the H2 molecules and cause the two hydrogen atoms to separate, or dissociate. This process, called “plasmon-induced dissociation of H2 on Au,” could improve the efficiency of certain chemical reactions.”In many important chemical reactions, the rate limiting step is the dissociation of closed shell molecules like a hydrogen molecule,” Nordlander told Phys.org. “If this reaction step can be ‘dealt with’ (using our demonstrated hot electron process), the reaction may proceed much faster and require less energy.” (Phys.org)—From petroleum refining to food processing, the vast majority of commercial chemical applications involve catalysts to control the rate of chemical reactions. Anything that can increase the efficiency of catalysts could have a widespread impact in these areas. In a new study, scientists have shown that an efficiency improvement may be possible by creating “hot” electrons (those with a very high energy) from a metallic surface on which the chemical reaction occurs, and using the electrons to control the chemical reaction and make it more efficient. Copyright 2012 Phys.org All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of Phys.org. To measure the dissociation, the researchers exposed the nanoparticle substrate to both H2 and D2 (two atoms of deuterium, a hydrogen isotope containing one neutron). If the hot electrons dissociated these molecules, it would result in the formation of HD molecules. The researchers found that, as soon as they turned the laser on, the rate of HD formation on the nanoparticle surface increased by a factor of 6. They also measured that the rate was strongly dependent on the concentration and size of the gold nanoparticles. The researchers explained that, in a sense, the electrons “do the impossible” because there would be no dissociation without them.”A hydrogen molecule adsorbed on a macroscopic gold surface does not dissociate spontaneously, even at elevated temperatures,” Nordlander said. “It is an impossible chemical reaction. The energy for dissociation is simply too large. We picked the hydrogen-gold system exactly for this reason. We wanted a system where the interpretation of the effect was straightforward. On other metals, like transition metals, a hydrogen molecule can dissociate spontaneously, in particular near defects and at elevated temperatures. But not on gold.”These results demonstrate how the field of plasmonics – which involves interactions between photons and nanostructures – can have applications in the field of catalytic chemistry, particularly photocatalysis, The researchers hope that this demonstration of the ability to control chemical reactions using light could be extended for specific uses. By using the laser frequency to tune the surface plasmon resonances, it may be possible to create hot electrons with specific energies that populate specific electronic states of molecules adsorbed on the nanoparticle surface. “The immediate application is to improve the efficiency of metallic catalysts by illuminating them with light,” Nordlander said. “Our groups have a very ‘green agenda’ and our intent is to design novel types of catalysts that are driven by sunlight. This is something we have an abundance of here in Houston. “Another important application is to investigate to what extent we can steer and control chemical reactions by having hot electrons of particular energies transferring into specific molecular orbitals. This is a relatively unexplored research topic. Normal electrons have positive energies and are much ‘hotter’ that our hot electrons. Such high-energy electrons typically do not stay on a molecule sufficiently long for the atoms to start to move.” In (a), (b), and (c), surface plasmons excited by a laser generate hot electrons on a gold nanoparticle surface. In (d), (e), and (f), hot electrons transfer to H2 molecules and cause them to dissociate. Since dissociation is the rate-limiting step in many chemical reactions, this hot electron process can increase the reaction efficiency.

Reviving the melodious folk songs of Arunachal Pradesh, Indira Gandhi National Art Center (IGNCA) organized the third series of ‘Sanjari’ program in New Delhi this Saturday. This program is organized every month and attempts to preserve the essence of the folk music of different states in its original form. On its 30th foundation day, original folk music was presented for the common people in Delhi. This edition of ‘Sanjari’ focused on Arunachal Pradesh’ cultural heritage. It is the country’s only state, where 26 major tribes and more than 100 sub-tribes reside. It is richest in terms of language, art, and culture. Arunachal has 90 languages and more than 100 folk tradition. The glimpse of Arunachal in its folk music was mesmerizing. Also Read – Add new books to your shelfDelong Padung, the first folk artist from Arunachal who is honoured with Bismillah Khan Award performed with his team. Their efforts engaged the young generation and created awareness of folk music losing its identity. “Today, we will sing the songs of ‘Adi tribe’. In the folk music tradition of Arunachal, these songs are sung all day and night and therefore, we do not have a short version of folk. But we are making it for the new generation,” said Delong Padung.

We are afraid that if we do not preserve it today, we will lose the identity of Arunachal. I am very grateful to IGNCA, who gave us this platform in the country’s capital and supported our movements of folk music,” he added.Delong Padung and his team from ‘The land of rising sun’ proved through their folk songs and folk dance that no matter what the language is, the music is appreciated and unite people.

Even when companies implement entirely cloud-based systems, they often use data backups and on-site storage in some way. These systems also fall under your responsibility.Just look at February’s StreetEasy breach, in which hackers stole information from a million accounts. Hackers didn’t access this information during the real estate company’s day-to-day operations; they stole it using a database backup from 2016. Personal information from those accounts — including email addresses, usernames, the last four digits of credit cards, expiration dates and more — is now available for sale on the dark web. This lesson is hard (and costly) for entrepreneurs: You have to protect data every step of the way.Related: 7 Surprising Places Hackers HideIronically, the myriad benefits of cloud-based data storage can become risks if businesses aren’t careful. Transactional data requests can be made and fulfilled from virtually anywhere in the world, using any connected device — when a physician’s office requests access to a patient’s hospitalization records, for instance, or when a customer purchases shoes online.This rapid-fire communication makes business operations run smoother, faster and far more efficiently. It also means that data can be left exposed unless you take the proper precautions. To protect your data through every transaction, take the following measures:1. Practice internet safety.Using virtual private networks (VPNs) and secure socket layer/transport layer security (SSL/TLS) helps ensure that your internet connection doesn’t leave you exposed when working with data that travels from one system to another. A VPN makes your connection private and keeps your online activity, IP address and device information anonymous. Use VPNs to access computers or networks remotely, especially if you or your employees are using public Wi-Fi.SSL/TLS encrypts and safeguards sensitive data as it’s transferred between two systems (such as client/server or shopping cart/browser), preventing would-be criminals from reading and modifying that information. When accessing a website to make a purchase, make sure that the address begins with “https,” which verifies that the site is encrypting and hiding your data from prying eyes.Related: 12 Simple Things You Can Do to Be More Secure Online2. Encrypt connected devices.Your encryption processes need to extend beyond the information you store in the cloud, especially with so many connected and external devices used in normal business operations. As a business owner, you must make sure that you encrypt any connected devices, hard disks, USB drives and related devices. Any unencrypted data stored on these devices endangers the privacy, finances and identity of your company and your customers.Some of the biggest international data breaches in history have been tracked back to infected USB drives, notably including a U.S. Department of Defense breach in 2008. For example, we had a healthcare client that was legally required to safeguard any devices that might contain patient health information (PHI). Unfortunately, someone stole a physician’s unencrypted laptop that contained patient records from his car during a lunch break, resulting in a violation that incurred a hefty fine (HIPAA violations can range from $100 to $1.5 million).Unencrypted data is like handing your wallet over to a stranger, including your credit cards, insurance cards and forms of identification. By encrypting your devices, you ensure that people cannot retrieve sensitive data from a stolen or lost hard drive without an encryption key.3. Multiple factors are better than one.What training does your company currently give employees about creating, storing and protecting their passwords? How does your company offer password-protected customer accounts? The reality is that most passwords aren’t secure — easy to remember usually means easy to hack.Businesses should use multifactor authentication (MFA) as a baseline. The principle behind MFA is that no single authentication factor is perfect. A second or third factor can compensate for the weaknesses of others. Supplement your password with one or two authentication factors that aren’t easy for other people to guess, using an authenticator on your mobile device, for example, or a biometrics factor like fingerprint or voice.Related: What You Need to Know About Multifactor Authentication4. Protect backups in the face of ransomware.When ransomware attacks a machine, backups are usually the last line of defense. This is why modern attackers are using more sophisticated programs to penetrate safeguards. In March 2018, the cybersecurity world was introduced to ransomware Zenis, which not only encrypts files but also purposely deletes backups until the victim meets the hacker’s demands.A 2017 Malwarebytes report found that ransomware detections were up 90 and 93 percent for businesses and consumers, respectively, and that these attacks are becoming more prevalent. Always protect hardware and software with anti-virus and anti-malware applications, or you’ll be an easy target.With the number of connected devices, data transfers and backups required to perform typical business operations, companies need to protect data every step of the way. Even with cloud storage or a cloud computing system, data can be vulnerable when it’s in transit, in backups or stored on unencrypted devices. Take the above steps to protect your data and your customers’ information.
