West Bengal Chief Minister Mamata Banerjee on Friday called the Rafale deal a “big scam” and said that she supported the views of the Congress party on this issue.One of the most vocal critics of the BJP-led government at the Centre, Ms. Banerjee has not spoken much about the Rafale deal. Asked about The Hindu’s revelations on the deal, the West Bengal Chief Minister said Mr. Modi is used to taking unilateral decisions and interfering in every issue and referred to demonetisation.“I was not sure how much money was involved but something has happened behind the curtains in the deal. Rafale is a big scam and I support Congress on this,” she said. The Trinamool Congress chairperson said Mr. Modi turns out to be a chaiwala (tea vendor) during the polls and becomes Rafale-wala after it. During his public meeting at Jalpaiguri Prime Minister Narendra Modi had said he had a deep bond with north Bengal which produces tea as he had once been a tea vendor. Row over circuit courtMs. Banerjee also took strong exception to the Mr Modi’s inaugurating the Circuit Bench of the Calcutta High Court at Jalpaiguri during the day.Speaking to journalists Ms Banerjee said neither the State government nor the High Court was informed of the inauguration. “The manpower for the Circuit Bench has to be provided by us. The High Court will send judges. It is like the groom and the bride are missing and the band party comes and plays a political tune,” the Chief Minister said.During his rally Mr. Modi had criticised the State government for the delay in opening up the Circuit Bench.
A railway court here has framed charges against Gurdaspur MP Sunny Deol and actor Karisma Kapoor in a 22-year-old case of alleged chain pulling in a train at the Naraina Railway Station in Rajasthan during the shooting for a film. The two actors challenged the order through a revision petition in a sessions court on Wednesday.Mr. Deol and Ms. Kapoor, along with stuntman Tinu Verma and Satish Shah, had allegedly entered the station and stopped train 2413-A Uplink Express by pulling its emergency chain in 1997, causing its delay by 25 minutes. The film unit was shooting for a movie Bajrang at Sanvarda village near Phulera in Jaipur district. The Assistant Station Master said in his complaint that a few persons from Mumbai shooting for a movie in a nearby village had illegally stopped the train.After framing the charges under the Railway Act earlier this week, the Additional Chief Metropolitan Magistrate (Railways) summoned three witnesses for the next hearing on September 24. The actors have been accused of violating Sections 141 (needlessly interfering with the means of communication in a train), 145 (drunkenness or nuisance), 146 (obstructing a railway servant in his duties) and 147 (trespass and refusal to desist from trespass) of the Railways Act.The revision petition filed in the sessions court stated that the railway court had framed the same charges for the second time after its charges read out earlier in 2009 were set aside in 2010. A.K. Jain, counsel for Mr. Deol and Ms. Kapoor, contended that the September 17 order for framing of charges was against the law.
Facebook Twitter Google+LinkedInPinterestWhatsAppProvidenciales, TCI, October 18, 2016 – The fourteenth governor since 1973 was sworn in Monday in Grand Turk and his welcome was both cordial and cautioning… both major party leaders assured the new His Excellency that the people of these islands are ready to support a mutually beneficial relationship, and both informed the Governor that there are some areas ripe for change.From the Opposition Leader, Hon Sharlene Robinson who spoke first and more extensively, there was talk about the now gone governor, being too soft on the current PNP Administration; she reminded the new Governor that his salary comes from the public purse. Hon Robinson addressed constitutional reform, calling for the Chief Financial Officer to be removed, for the Governor’s House of Assembly appointments to be reduced from two and said that crime is the top concern and the response has not been vigorous enough by the British who head the country’s National Security.The Premier, Hon Dr Rufus Ewing similarly wants the CFO gone, said the UK needs to prove itself honorable and support a bill to make that happen, that there should also be a bill to return the powers of land distribution to elected leaders and a crime strategy and lead appointments should also be managed by those elected to serve.The new Governor is Dr John Freeman and he was complimentary to the islands, adding that he is here as a guardian of our way of life. His wife, Corinna was presented a special bouquet by 7-year-old Maliha Lightbourne of Susanna Wesley Methodist School, from the A company of the Brownies & Girl Guides. HE Dr. John Freeman was sworn in by Chief Justice, Margaret Ramsey-Hale at the now refurbished House of Assembly, NJS Francis Building in the Capital.

Toyota Motor Corp’s Executive Vice President Mitsuhisa Kato speaks in front of the company’s fuel cell vehicle (FCV) concept car at the 43rd Tokyo Motor Show in Tokyo November 20, 2013. Toyota and Honda are taking the lead in this largely untested market.Toyota’s FCV Concept is inching closer to reality and the car which has been the talk of the town is all set to dazzle at the 2014 Consumer Electronics Show (CES) in Las Vegas on 6 January. The latest FCV which made its first appearance at the recently concluded 2013 Tokyo Motor Show is expected to go into production in 2015.The FCV; a hydrogen fuel-cell passenger vehicle from the renowned auto maker Toyota, will draw power from its fuel-cell stack and two 70 MPa high-pressure hydrogen tanks beneath the specially-crafted body. It will run on the compressed hydrogen power, which is a clear alternative to the usual gasoline-powered and plug-in cars, but the success of the hydrogen fuel-cell concept is still debated. In a world where the fossil fuel is running out, fuel-cell cars seem to be the only way. Toyota Motor Corp’s FCV concept car is seen at the 43rd Tokyo Motor Show in Tokyo November 20, 2013. Toyota wants this on the road by 2015.(Reuters)Although Hydrogen vehicles have been in news for a while now and many companies have been considering the idea, the concept has been tantalizing because of the many hurdles. Now companies like Toyota, Hyundai and Honda could clear the stumbling blocks and introduce the all-new hydrogen cars into the auto world.When Toyota FCV becomes a reality, the car will rival the Honda FCEV concept, which is also expected to mark its entry in 2015. But road to success is not straight and problems like supply of hydrogen still need to be addressed more seriously. The vehicle is also likely to boast a high price tag.Toyota Motor Corp’s FCV concept car is seen at the 43rd Tokyo Motor Show in Tokyo November 20, 2013.

Representational image.PixabayThe bulls are on the rampage on the Street revved up by foreign buying and the brightening prospects of the return to power of Prime Minister Narendra Modi after the Balakot bomb run in retaliation to Pulwama attack. Sensex, the 30-scrip benchmark index of Bombay Stock Exchange (BSE) surged about 1,000 points in six sessions of March in what is seen as the beginning of a long rally to close on Tuesday at 37,535 points. The broader 50-index National Stock Exhange (NSE) Nifty clocked about 400 points to close at 11,301 points.Indian rupee touched a new 2-month high on the back of strong foreign buying of both debt and equity. Market observers see renewed risk appetite in foreign institutional investors (FII), who have poured in about Rs 8,000 crores so far this month, according to a report in the MoneyControl website. FIIs sustained net inflows in February and January pumping in Rs 13,564 crores and Rs 127 crores respectively. Foreign portfolio investors (FPI) have also been supporting net inflows having brought in a net amount of Rs 11,182 crores last month.Market watchers are confident of a continued bull run this time unless there is a disastrous political turn as the rally has been broad based with strong movement in all sectors. The Nifty Bank index on Tuesday surpassed its all-time closing high of 28,320 hit on August 9, 2018, to hit a high of 28,363 in the intra-day trade, the Business Standard website said. The most active stocks on NSE were Reliance Industries (RIL), ICICI Bank, Axis Bank, Titan Company and UPL hitting their high.The bullish turn is attributed in part to the market euphoria over polls that have predicted a return of the Bharatiya Janata Party under Prime Minister Narendra Modi.The mid-and small-caps have been gaining traction among the investors after having bled for more than a year. Experts are bullish on the segment because of their favourable valuation. Prime Minister Narendra Modi addresses during a programme at Greater Noida, Uttar Pradesh on March 9, 2019.IANS/PIBChandresh Nigam, managing director and chief executive officer (CEO) of Axis Mutual Fund, had told Business Standard recently: “We have seen increased flows from HNIs in the mid- and small-cap schemes in the last four-five days. Sophisticated investors are taking tactical calls on the mid- and small-cap categories. There has been sustained correction in some of these categories. Some wealthy investors see this as a good time to deploy their funds.”The bulls have also found traction in the revised notes by foreign brokerages such as HSBC, BNP Paribas and Morgan Stanley on Indian equities. HSBC recently raised its weightage on India from ‘neutral’ to ‘overweight’ and remains bullish on financial, metal, and consumer discretionary sectors in the Indian context, according to a report.”Aside from the elections, the macro backdrop is looking better in 2019 than in 2018. Inflation is low, and our economists are now looking for a rate cut in April. We expect overall GDP (gross domestic product) growth to accelerate, possibly supported by reforms (such as GST) starting to bear fruit,” Herald van der Linde, head of equity strategy for the Asia Pacific at HSBC wrote in a note along with Devendra Joshi and Prerna Garg. The global cues have also been conducive for the Indian bull run. The Asian shares have been upbeat after the European Commission’s nod for changes to a Brexit deal ahead of a vote in the British parliament. European Commission head Jean-Claude Juncker agreed to additional assurances in an updated Brexit deal with British Prime Minister Theresa May on Monday, according to Reuters. The easing of trade war clouds between the US and China have also helped the global markets, reflecting the shine on Indian equities.
BNP chairperson and former prime minister Khaleda Zia holds a Rohingya child in her arms while visiting Rohingya camp in Balukhali of Ukhia, Cox’s Bazar. Photo: BNP Bangladesh Nationalist Party chairperson Khaleda Zia on Monday urged the government and international community to intensify diplomatic efforts to resolve the Rohingya crisis, reports UNB.She made the call while talking to newsmen after distributing relief materials among displaced Rohingyas at Moynargona Rohingya camp in Ukhiya.The BNP chief also urged Myanmar to take back its nationals ensuring their security and citizenship for the sake of humanity.”We think the Rohingya crisis won’t be resolved only by distributing relief materials. The Rohingyas will have to be repatriated through discussions and strong diplomatic efforts so that they can live their own country with security and without fear,” she said.Mentioning that the government could not yet take any effective step to resolve the Rohingya problem, Khaleda said, “The Bangladesh government must strengthen its diplomatic efforts to send back the Rohingyas. Alongside, the international organisations will have to take responsibility for repatriating them on humanitarian ground.”The BNP chief called upon the international community to come forward to ensure the safe return of Rohingyas to their own country. “I appeal to the international organizations: You please translate your words into actions to overcome the problem.”Khaleda said the international community should understand Bangladesh is a poor, small and densely populated country. “Though we’re poor, we have got the big heart and we love people. That’s way locals are making their best efforts and providing money from their pockets to ease the pains and sufferings of the Rohingyas.She further said, “But it’s not possible for us to bear it for a long time. So, Myanmar should take steps to take their citizens back to their country as early as possible as winter is approaching fast as the rainy season is over.”Khaleda Zia arrived at Ukhia around 1:00pm to visit four Rohingya camps and a medical camp set up by pro-BNP physicians’ body, Doctors’ Association of Bangladesh (DAB). She will return to Chittagong later in the evening.
The bus service with Rajshahi from 12 districts including Dhaka, Pabna, Natore was halted for almost 12 hours on Thursday without any prior announcement, subjecting commuters to tremendous trouble throughout day. Photo: Prothom AloThe major opposition and Jatiya Oikya Front ally Bangladesh Nationalist Party (BNP) alleged that bus service from 12 districts with Rajshahi was halted in order to obstruct the Oikya Front’s rally scheduled on Friday.Jatiya Oikya Front (National Unity Front) is to hold a public rally at around 2:00pm at the Madrasa grounds in Rajshahi.The bus service with Rajshahi from 12 districts including Dhaka, Pabna, Natore was halted for almost 12 hours on Thursday without any prior announcement, subjecting commuters to tremendous trouble throughout day.Members of Natore Bus Owners Association and Rajshahi Transport Workers Union have given contradictory statements in this connection.Earlier on Tuesday, the Oikya Front organised a rally in Suhrawardy Udyan in the capital. A number of vehicles were prevented from entering Dhaka for ‘security reasons’ on the day.Passengers and vehicles drivers complained that they had to face interminable traffic congestion due to the police checks along the way. Also, bus movement was closed at one stage on the Dhaka-Chittagong Highway in the Signboard area at the time.Earlier, BNP chairperson’s adviser Mizanur Rahman Minu talked to the media in a press conference at Rajshahi BNP’s office at noon on Thursday.“We got written permission for the rally on 12 conditions just 14 hours before the due date. Bus service was halted to hamper the gathering,” Minu told the media.Alleging that the police have been arresting BNP leaders and activists ahead of the rally, the adviser to the BNP chairperson said, “Police raided the houses of hundreds of BNP leaders and activists. Some over enthusiastic and ambitious police officers are creating obstacles before the rally in many ways.”In response to BNP’s allegations, Rajshahi metropolitan police spokesman Ifte Khair Alam said, the police were performing their regular duties and were not creating any obstacle. There was no incident of politically motivated arrests.Natore Bus Owners’ Association general secretary Sajidul Islam told Prothom Alo that they received a letter from the transport workers union saying a bus driver of Desh Travels was assaulted on Wednesday and they would close the bus service until legal action was taken.However, when the Prothom Alo correspondent contacted Desh Travels counter officials, they said that they did not know of any such incident of a driver being assaulted.Meanwhile, several bus drivers told Prothom Alo that they started out with passengers from Rangpur in the morning. After reaching Bogura, the owners and workers blocked their buses.A transport owner of Bogura said on condition of anonymity that police and Awami League-backed transport owners had restricted them to drive to Rajshahi.Bogura highway police denied such allegations.On the other hand, the convener of Rajshahi District Motor Workers Union Kamal Hossain said, the bus service was halted due to the dispute between the two Bus Owners’ Association of Rajshahi and Natore.

Photo: AFPSaudi Arabia dismissed on Saturday accusations that Jamal Khashoggi was ordered murdered by a hit squad inside its Istanbul consulate as “lies and baseless allegations”, as Riyadh and Ankara spar over the missing journalist’s fate.As the controversy intensified, the Washington Post reported Turkish officials had recordings made from inside the building that allegedly proved their claims Khashoggi was tortured and killed at the consulate.A Saudi delegation arrived in Turkey for talks, officials said on Friday, with the case risking fragile relations between the two.In the first Saudi ministerial reaction to the accusations about Khashoggi’s killing, interior minister prince Abdel Aziz bin Saud bin Nayef said that “what has been circulating about orders to kill him are lies and baseless allegations”.The Kingdom “is committed to its principles, rules and traditions and is in compliance with international laws and conventions”, he added according to the official Saudi Press Agency.The case risks damaging the image of the kingdom and its ties to the West as crown prince Mohammed bin Salman promotes a reform drive at home.Big names from media and business have already cancelled appearances at a major conference in Riyadh this month.Saudi journalist and Washington Post contributor Khashoggi vanished on 2 October after entering the consulate to obtain documents for his upcoming marriage.Turkish government sources say police believe he was killed but Riyadh denies that.Did he leave?The Saudi delegation, whose composition was not immediately clear, is expected to meet with Turkish officials in Ankara at the weekend, state media said on Friday.It is likely that they will take part in a joint working group on the case, whose creation was announced Thursday by Turkish presidential spokesman Ibrahim Kalin following a request by Saudi Arabia.A Saudi official source quoted by SPA news agency said it was “a positive move” Turkey had agreed to the creation of what it described as a “joint action team” over Khashoggi’s disappearance.The Turkish leadership has so far stopped short of accusing Saudi Arabia, although pro-government media have published sensational claims, including that an “assassination team” was sent to Istanbul to kill Khashoggi.In a rare public comment on the case by a Saudi official, Saudi Arabia’s ambassador to Britain, prince Mohammed bin Nawaf al Saud, told the BBC that Riyadh was “concerned” about its citizen.Turkish president Recep Tayyip Erdogan has challenged Saudi Arabia to provide CCTV images to back up its account that Khashoggi left the consulate safely.Khashoggi, a Saudi national living in the US since September 2017 fearing arrest, criticised some policies of Mohammed bin Salman and Riyadh’s intervention in the war in Yemen.The Washington Post reported the Turkish government has told US officials it has audio and video recordings which show how Khashoggi was “interrogated, tortured and then murdered” inside the consulate before his body was dismembered.Turkish officials contacted by AFP refused to comment on the veracity of the report.Visual’ search onlyAnkara and Riyadh have been on opposing sides in the region on key issues, including the ousting of the Islamist Egyptian government and last year’s Saudi-led blockade on Turkey’s regional ally Qatar. Yet as key Sunni Muslim powers they have maintained cordial relations.But despite Riyadh’s agreement on Tuesday to let Turkish authorities search the Saudi mission, the probe has not yet taken place. The two sides have been in intense contacts to resolve the issue, local media reported.Pro-government Turkish newspaper Sabah said the search of the consulate had not yet happened because Saudi officials would only allow a superficial “visual” probe.The Turkish side did not accept the offer and Sabah said officials wanted to search the building with luminol, a chemical that allows forensic teams to discover blood traces.Officers were looking into sound recordings sent from a smart watch that Khashoggi was wearing when he was inside the consulate to a mobile phone which he gave to his Turkish fiancee waiting outside, Hatice Cengiz.Milliyet daily reported that “arguments and shouting” could be heard on the recordings, but Sozcu newspaper said only “some conversations” could be heard.Chilling effectBloomberg, the Financial Times, The Economist and The New York Times withdrew as media sponsors from the second Future Investment Initiative to be held between 23-25 October in Riyadh dubbed “Davos in the Desert” after the World Economic Forum in the Swiss resort.The CEO of ride-hailing app Uber, Dara Khosrowshahi, said that he will no longer be attending the event unless “a substantially different set of facts emerges”.British entrepreneur Richard Branson said he would suspend two directorships linked to tourism projects in Saudi Arabia over concerns about the missing journalist.Amnesty International demanded the Saudi authorities reveal what happened to Khashoggi as it said Riyadh was “responsible at a minimum for enforced disappearance”.
Greg Banks, M.D. always has been passionate about boxing and mixed martial arts. But being a doctor is what forced him into a corner … literally. An intimate knowledge of the dangers of ring competition, as both participant and spectator, inspired the family and urgent-care physician to moonlight as a guardian of these combatants.Greg Banks moonlights as a ringside doctor in Richmond Va. (Courtesy photo)Banks has been a Washington, D.C.-area ringside doctor at boxing and MMA events for a decade. He is driven by his love of these sports and his commitment to help people.“I would see these guys ringside in a corner and wonder: ‘Who’s that with a stethoscope?’”That curiosity ultimately led Banks to secure his license through the Association of Ringside Physicians. He soon became that guy ringside, with the stethoscope.“It’s a very significant job because of the physical nature of the sports,” said Dr. Gregory Pleasants, who has served for 15 years as a Richmond, Va.-based ringside doctor. “I have worked some fights with Greg, and he has a real passion for the sports to go with his passion for service.”“For me,” said Banks, 52, “as someone who loves the sports and studied taekwondo, too, it’s a great opportunity to have a great seat to see the matches. Most important, though, it’s very dangerous to compete in these sports, and the ringside doctors are there to help minimize injury — especially brain injury.”The native Washingtonian and Howard University College of Medicine graduate said his job is both entertaining and gratifying.“The doctor is mostly in the shadows — until something happens,” he said. “It’s scary sometimes. But, most of the time, the injuries are cuts or maybe a broken bone, sprains. When I’m not worried about the fighter, I’m actually having a great time because I have the best seat in the house.”But Banks said there are many factors in boxers or MMA fighters who suffer serious brain damage — and it’s not just because of hard punches. Participants often undergo dramatic weight loss just before fights to meet weight requirements. Banks explained that quickly losing and regaining weight can spell trouble.“Dehydration comes with weight-cutting,” Banks said. “Their whole goal is to come into the fight as big and strong as possible, to inflict as much pain as possible. But with weight-cutting, you lose weight all over.“In the brain, there is something called CSF [cerebrospinal fluid] that helps cushion the brain. But when you’re dehydrated, there is less of that cushion, that fluid. Quick weight gain won’t allow you to function at your premium and you won’t be as protected. So, your brain can get hit with the first blow and then bounce off the other side of the skull. So that’s a double concussion that can cause tearing of the blood vessels in the brain, causing bleeding, which is never good.“It’s a big science. [Doctors are] looking at it each year: ‘What can we do to prevent [traumatic brain injuries] from happening?’ One thing we’re looking at is dates, so boxers have a deadline to make the weight that’s not so close to the fight, giving the body enough time to replace that fluid.”Banks said that doctors continue to seek ways to detect performance-enhancing drugs. They contribute to severe injuries because they “allow guys to train longer, get more muscle mass on their bodies and withstand more injuries. And they are able to inflict more injuries on their opponents because their strength is off the scales.”Banks started his medical journey as a teenager. He hoped to become a marine scientist. But when that discipline bored him, Banks’ physician father asked him several questions and then said: “You want to help people? Then maybe you should be a doctor.”“Then he walked away,” Banks said. “No pressure.”But the idea took root. At age 18, he began the trek that led him to his family-medicine practice in Front Royal, Va. His service as a ringside doctor has been just as rewarding.“Back in the day, getting your residency was like going through war,” he said. “And with that, you got something engrained in your character: Everyone’s a patient. When you see someone who looks like they are about to get into trouble, that stuff from my training kicks in. … And trouble is where the ringside physician steps in. No. 1, above all, is to protect the fighter. That’s more of a thrill than watching the fights.
(Phys.org) — Since the first demonstration of microelectromechanical systems (MEMS) in the mid-‘80s, the technology has not proven as useful as originally anticipated. One of the problems is that the tiny components tend to stick together due to strong surface adhesion forces on the nanoscale, an effect that engineers call “stiction.” Now in a new study, scientists suggest that this problem might be solved by inducing quantum levitation between components, which they demonstrate by simply adding a thin metallic coating to one of the interacting surfaces. Journal information: Applied Physics Letters Explore further Researchers see exotic force for first time More information: Mathias Boström, et al. “Ultrathin metallic coatings can induce quantum levitation between nanosurfaces.” Applied Physics Letters 100, 253104 (2012). DOI: 10.1063/1.4729822 By preventing stiction, quantum levitation may offer a way to prevent surfaces used in MEMS and nanoelectromechanical systems (NEMS) from crashing together due to other attractive van der Waals forces that exist between them. Since the thickness of the nanocoating changes the dielectric properties of the interacting surfaces, researchers would have to precisely determine the correct thickness for a desired levitation distance. If the technique works, it may provide a much needed revitalization of the fields of MEMS and NEMS.In the future, the researchers plan to extend their investigations to other materials, such as zinc oxide and hafnia, which are widely used in microelectrical and microoptical devices. They also have an upcoming paper (arxiv.org/abs/1206.4852v1) in which they investigate the repulsive and attractive forces between excited Cesium atoms that are confined in a nanochannel, which are very different from those in free space.“Two Cesium atoms that are close together and in an excited state can form unusually large molecules when they are between two gold surfaces,” explained coauthor Mathias Bostrom of the Norwegian University of Science and Technology in Trondheim, Norway, and Australian National University in Canberra, Australia. “The effects from retardation for these excited state interactions between atoms are very similar to what we found for the Casimir-Lifshitz force between a gold-coated silica surface and a silica surface in toluene. Hence we found long-range attraction that brings the atoms together and short-range repulsion enabling bound states (preventing the atoms from crashing together, i.e., forming super large molecules).”Finally, the researchers plan to further investigate how quantum levitation may be used for NEMS systems by looking at anisotropic effects, which are the different properties that arise when parallel or perpendicular to the material interface.“Our colleagues in Oslo (Professor Clas Persson of the University of Oslo and his team) have calculated the actual optical properties of the materials (the dielectric function) for thin gold sheets which will be used to investigate how anisotropic effects may influence NEMS systems with gold nanocoatings. It is likely that the range with repulsive forces (preventing the system from crashing together) may be influenced in such improved calculations. Our aim is to do such calculations this autumn.” Two pieces of silica – one with a gold nanocoating – will experience a repulsive Casimir-Lifshitz interaction beyond a critical distance. Without the gold nanocoating, the interaction would be attractive at the same distance. Image credit: Boström, et al. ©2012 American Institute of Physics The team of researchers, from institutions in Norway, Australia, and Sweden, has published the study on quantum levitation between nanosurfaces in a recent issue of Applied Physics Letters.The odd thing about this levitation is that it stems from the Casimir-Lifshitz force, which has the unusual property of being either attractive or repulsive. As a type of van der Waals force, it arises between nearby particles due to their inherent electrical properties. In this study, the scientists looked at the Casimir-Lifshitz force that occurs between two silica surfaces in a liquid (either bromobenzene or toluene). Normally, this force is attractive, but it weakens as the silica particles move further apart. This weakening is called retardation, and the researchers found that they could decrease the distance at which retardation occurs by coating an ultrathin layer of gold on one of the silica surfaces. This small modification shifts the retardation regime from a separation distance of several nanometers down to a few nanometers by modifying the dielectric properties of the coated silica surface. In fact, retardation weakens the attraction so much that the force becomes repulsive when the surfaces are separated by a few nanometers or more, at a critical distance called the levitation distance. Below the levitation distance, the force again becomes attractive, while above this distance it becomes increasingly repulsive up to a maximum point. At still larger distances, the repulsion stabilizes below the maximum value. The ability to control the Casimir-Lifshitz force is not completely new. Scientists have known about these effects theoretically since the 1970s, but only recent advances in nanotechnology have allowed for experimental investigations. “The interaction between two silica objects in toluene is attractive,” coauthor Bo Sernelius of Linköping University in Sweden told Phys.org. “Previous studies have shown that, if one of the objects is replaced by a solid gold object, the interaction turns repulsive for distances beyond the levitation distance. Thus there is a potential barrier that reduces the chance for the objects to come close and stick to each other. We found, and this is new, that if instead of having a solid gold object we had a silica object with a thin gold coating, the levitation distance shrunk and the barrier became higher. The chance of preventing stiction increased considerably.” Copyright 2012 Phys.org All rights reserved.

Experimentation. Entertainment. Instilled with energy. The third phase of Short and Sweet, organised by Shoelace Productions was a complete stunner. Not the conventional words to use in a play review maybe. But these are thoughts that came to mind as the festival draws to a close.Held at Epicenter in Gurgoan, these set of ten plays rocked, as festival director Deepak Dhamija made sure that festival-cum-competition sailed through smoothly.Unbelievably funny, Also Read – ‘Playing Jojo was emotionally exhausting’Dickheads (offended anybody?) was my personal favourite, which was dished out as a surprise. Written by Ashwath Bhatt and directed by Vivek Shrivastava, this play is about the lives of two street children who eventually become superstars. The story is simple yet compelling, with splendid performances. While 2922, written and directed by Arnav Nanduri and Pranay Manchanda, gets audience attention through a musical journey laced with humour.Who’s the Boss makes you laugh all through, with a secretary sitting on her boss, caught in an uncomfortable situation, being tied together. The lesser said about Also Read – Leslie doing new comedy special with NetflixNine types of Ice the better. Designed and directed by Himanshu Mehta, Chup was more compelling.So was Chairpersons, written and directed by Rajiv Rajaram. It is a political satire, which encapsulates the contemporary Indian political scenario, comparing power dynamics to a game of musical chairs.Smart and slick writing, executed by amazing performances by Rajaram Sandeep John and Nikhil Sriram make this play a treat for theatre lovers.Solitary Creeper , which captures Delhi life as people bump into each other during metro rides was a fun watch. Arvind Gaur’s Khol Do was a compelling watch too with some actors making a lasting impact which includes Shilpi Marwaha and Gaurav Mishra. The evil effects of smoking was nothing more than a over-dramatic monologue. But even A Different Client directed by Vivek Mansukhani, experiments with a different concept complimented by a powerful performance by Mansukhani.After these three rounds, the list of ten plays who have made it to the finale of Short and Sweet, to be held this Friday at Kamani, was announced which includes – 2922, Chairpersons, Dickheads and A Different Client from this round. While from the earlier two rounds, plays which have made it include the superbly humorous Lyra directed and written by Aishwarya Jha Mathur, the amazingly directed The sum of your experiences with the stunning performance of Damandeep Sidhu, well conceptualised and executed Unit Test, superbly performed Between Romeo and Juliet, interestingly executed Gandhi, Chaplin and Salt and Juhi Goel’s fabulous Dhalti Shamein.Catch the the Gala- finale at Kamani on 14th December 7:30 pm, log on to www.bookmyshow.com

The optimization thing is in my blood,’” Richey said.With Slide Contacts, users can see their associates in a “favorites” list, and slide right on a contact to call them, slide left to text message or slide way left to email. (Check out this quick tutorial.)Slide Contacts debuted in Apple’s App Store in June, with a more cleanly designed version launching last month. Richey plans to roll out an Android version next year.Market opportunityA review from Appsfire, an app for discovering other apps, helped spur 12,000 free downloads of Slide Contacts when it first hit the App Store, Richey says.Kyle Richey launched Pure Signal to feed his need to create apps. The company’s second app, Slide Contacts, helps people reach out to favorite contacts in a jiffy.Slide Contacts has since been selling for 99 cents a pop, and has more than 15,000 users.“All the positive feedback emails have been very encouraging, especially the people that have put it in their dock. … I’ve noticed a lot of people saying they’ve completely stopped using the phone and messages app on their home screen,” Richey says.He suspects that it is not as much an app for social networking, the app’s original category, in which it reached No. 6 in the App Store. Rather, Slide Contacts is more a time-saving tool for people who are juggling work and family commitments. It has since been moved to the productivity category.Related: Independent App Developers, Meet TrepLabs“It’s productivity all the way,” Richey said. Plus, he’s found that users really like the “cool” factor of the app’s sliding gestures, minimalist design and 10 themes to customize the look and feel of the interface.ChallengesStill, great design doesn’t always translate into more sales. Richey learned this lesson the hard way with his last app, CalcForm. About $19,500 in development expenses produced $500 in revenue over two years.With Slide Contacts, he says he has been much more conscientious about getting his idea validated. For instance, he tapped his friends and family and of course random strangers to test out the app.“The validation is key,” says Richey. “Show people the prototypes. Ask people a bunch of questions.”Strengths Seems simple enough, but Richey has proven himself to be a strategic thinker. He started Conquer Apathy two years before his college graduation, and then flipped the profits over to his new Pure Signal venture in 2011. He learned from the stumble over CalcForm.And Pure Signal already has a beta version of a goal tracker app called Strides that has been quietly selling for $2.99 in the App Store with little to no promotion. The official launch of Strides is planned for December, before the New Year’s resolutions season, and a web version is in the works so users can sync their goals across all their devices.Related: In Mobile Gaming, the ‘Eyes’ Have ItEven so, the task at hand is Slide Contacts and how to position it. One possibility could be to give it up for free, then sell premium versions of the app with more customization options. “We’ve talked about doing it as a mass market thing,” Richey says.What do you think he should do?

Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now 5 min read For many people, digital currency is an abstract concept that’s seemingly beyond understanding. For Jackson Palmer, a full-time marketing product manager at Adobe, however, cyber currency took on a whole new dimension when a well-timed joke ballooned into the $30-million network known as Dogecoin, an open-source, peer-to-peer digital currency.To get the inside scoop on this incredible story, I sat down with Dogecoin founder Palmer for some interesting insights into the world of digital currency and his unexpected rise to fame.The launch of Dogecoin.Palmer didn’t set out to launch a new currency — all he did was make an innocent Twitter joke proposing “Dogecoin” in the wake of Bitcoin’s intense press coverage and an article on the Gawker website marking 2013 as the year of the Doge meme. Digital-currency enthusiasts latched on to the idea, and Palmer was able to change Bitcoin’s code to include the Comic Sans exclamations that are part of the Shiba Inu-based meme.Image credit: DogecoinThis was enough to launch the currency and corresponding website in just a few hours and, according to Palmer, “The rest, as they say, is history.”Related: Bitcoin Is Now Classified as a Commodity in the U.S.Understanding digital currency.To understand the massive impact of Dogecoin, you first need to understand how digital currency works.“Just think of it as a digitized credit,” Palmer says.Essentially, cryptocurrencies such as Bitcoin and Dogecoin operate by creating a massive, open ledger that records every transaction that has ever occurred on the currency’s network. Individual users are given a “public key” (basically, a long stream of digits than can be represented as a QR code), which can be used to either send or receive funds for a small fee.Where things get really interesting, though, is that every single device that records a balance in a given digital currency — whether Bitcoin, Dogecoin or another alternative — maintains a record of the full network’s transactions. So while traditional banks and services such as Paypal are vulnerable to system-wide outages stemming from major hacks, digital-currency markets can carry on as usual, thanks to their decentralized nature.Is digital currency safe?For the most part, cryptocurrencies’ infrastructure keeps them safe, as developers would need to get more than 51 percent of the network to agree to changes in the way that the currency operates. Even the fees generated by digital-currency transactions contribute minimally to fraud because the fees go to the data miners who push updates to the network successfully, not to owners or investors who could abuse the system for profit.That’s not to say that safety issues don’t exist. The Mt. Gox bankruptcy, for instance, demonstrates that services built of digital currencies can be as susceptible to hacking attacks as traditional banking institutions. PCWorld also acknowledges that digital currencies aren’t protected or insured by anybody, so if your computer (or your cryptocurrency wallet-hosting service, as in the case of InstaWallet) is hacked, these irreversible transactions could result in losses.However, programs such as these can also be used for good. Palmer attributes the growth of Dogecoin to the early creation of a bot that lets website readers “tip” site writers with small amounts of real currency (rather than just a Facebook “Like”).“People liked the idea so much that they started tipping their friends who had never heard of Dogecoin, so it created a sort of built-in virality,” he says.Related: Citigroup Is Testing Its Own Bitcoin: ‘Citicoin’Lessons from Dogecoin’s growth.As a technical marketer by trade, Palmer had quite the learning curve to get up to speed with cryptocurrency basics. His overnight education, along with the network’s surprising success, led him to a few interesting revelations:1. Be innovative.Now an advocate for online payments as a whole, Palmer estimates that cash could be obsolete in as little as 20 years. Getting there, however, will require both innovative new technologies such as Dogecoin and the adoption of these new products and services by a wide enough pool of customers to become self-sustaining.Palmer sees tremendous potential in these technologies, and encourages others to look forward to the possibilities that the future holds for digital currencies.2. Be aware of what you’re selling.Palmer argues that all marketers, including those in cryptocurrencies, should be aware of what they’re selling. He’s made it a point to take on small side projects throughout his career that give him the opportunity to learn new skills. Apart from his endeavors in digital currency, he also learned web development to ensure that he could communicate clearly with Adobe’s customers.You can do the same. Look for opportunities to develop complementary skill sets, then pursue them, even if you have to do so in your off hours.3. Don’t be afraid to fail.“All too often, people are afraid to get something off the ground because of what might happen, but you never know until you try,” Palmer says. “Don’t worry about what will happen if something fails, but think about what you’ll get out of it in terms of personal growth.”For more great insight, check out the full interview with Dogecoin’s Palmer:Have you ever used Dogecoin or any other cryptocurrency?
