Tradeshows Post Moderate Growth in 2014


first_img “We are optimistic for the performance of the industry overall this year. Economic and job growth should continue to drive expansion in exhibitions,” says Allen Shaw, CEIR economist and chief economist for Global Economic Consulting Associates, Inc. The tradeshow industry continued its steady recovery following the market collapse in the late 2000s, according to the Center for Exhibition Industry Research (CEIR). The CEIR Index, a composite figure that accounts for net square footage (NSF), number of exhibitors, attendance and revenue of all major U.S. tradeshows, was up 1.8 percent last year. While the growth is slightly off the projected 2.0-percent return, it marks the fourth-consecutive year of positive gains. The group is forecasting continued improvement over the next three years, as well. Projections show 2.8-percent growth this year, followed by 2.4- and 2.0-percent gains in 2016 and 2017, respectively. Market-by-market performance varied considerably in 2014. Up 5.2 percent, financial, legal and real estate shows were at the top of the industry, followed by building, construction, home and repair (5.1 percent) and food (4.4 percent). Education (-3.0 percent), machinery and finished business outputs (-1.0 percent) were at the opposite end of the spectrum.last_img read more

IBTimes Special Revisiting all Cricket World Cup Finals 1975


first_imgClive Lloyd lifting the maiden World Cup trophyTwitter/Cricket World CupThe upcoming ICC 2019 World Cup will be the 12th edition of one-day international cricket’s biggest event. 11 previous chapters have produced many memorable moments as well as some really disappointing ones. This 12th episode of the event promises to be one of the best, if the weather doesn’t play spoilsport – a possibility that can never be ruled out in England.The Final of this mega event has seen many different types of contests and performances. From some utterly sublime to those extremely anti-climactic. The 11 Finals have not always lived up to the expectations but have often produced great displays of batting and bowling skills.As we get ready for the latest edition of ODI cricket’s showpiece event, let’s walk through the pages of history and remember the most important features of the Finals of all 11 previous World Cups. In the first part we look at the decider of the very first World Cup.1975 – Australia vs West Indies (Lord’s)When the first edition of World Cup was played, most teams were not sure how to approach the tournament. It may not have been seen as that important also. West Indies, then starting to emerge as a powerful team and developing a formidable pace attack took on a strong Australian side in the Final at Lord’s. A large crowd of West Indian supporters, largely immigrants from the Caribbean, descended on cricket’s most hallowed arena to support their team. ICC World Cup 2019 – Team India Squad West Indies batted first and the most important moment of the Final came when Clive Lloyd was dropped off the bowling of Dennis Lillee on 26. This mistake proved to be very costly and the West Indian skipper, in the words of his Australian counterpart, Ian Chappell, ‘caned’ Australia. At a time when Sunil Gavaskar was happy to bat out all 60 overs of an ODI to score 36 not out, Lloyd smashed 102 off just 85 balls. West Indies ended up with 291/8.The Caribbean side didn’t have their famed four-man pace attack then. The only prominent name in the bowlers list was Andy Roberts. But a man destined to become one of the greatest players of all time made a huge difference. Except that he did it in a different capacity than the one he is known for. Vivian Richards played a key role in Australia’s inability to chase the target by producing three run-outs, including a brilliant one of Ian Chappell, the leading run-scorer for his team in that match. At a time when fielding was largely an afterthought, Richards showed his athleticism to great effect. Ian Chappell was left gobsmacked by the fact that Richards could even get to the ball which he thought was easily going to the boundary.At 233/9, it seemed all over for Australia but then, the legendary duo of Lillee and Jeff Thomson started resisting with the bat and suddenly, Australia seemed to be in with a chance. But that was snuffed out by, quite aptly, another run-out, the fifth in the Innings. With Australia falling short by 17 runs and 8 balls remaining in the innings, West Indies became the first World Champions in the sport, a harbinger of things to come.center_img Closelast_img read more


AlQaeda says Pakistani security forces detained wife of its chief Zawahiri


first_imgScreen capture from the video showing al-Qaeda leader Ayman al-Zawahiri.SITE Intelligence GroupPakistani security forces have detained the wife of Al-Qaeda chief, Ayman al-Zawahiri, and two other family members of the groups ‘martyrs’ for nearly a year, according to a statement released by the insurgent group on Friday.Al-Qaeda claimed that “treacherous Pakistani forces” captured the family members including Al-Zawahri’s wife a year ago as they left Waziristan, a former Taliban base bordering Afghanistan due to airstrikes, reported Associated Press.”We … hold Pakistan’s government and its treacherous army and their American masters responsible for their criminal acts,” the statement said.The current leader of Al-Qaeda, al-Zawahri is an Egyptian who took over the group’s leadership after US military forces killed Osama bin Laden in Pakistan’s Abbottabad region in 2011. While Pakistan has not commented on the statement, Zawahiri is said to be hiding in the country.Al-Qaeda’s statement came a day after US Secretary of Defense Mark Esper confirmed the death of 9/11 mastermind’s son, Hamza bin Laden.The US official confirmation comes weeks after it was reported that he was killed during the last two years in an operation that involved the United States. Hamza who is believed, to be 30 years old, may have been killed before the US announced a $1 million bounty on him in February 2019.According to the documents found in the Abottabad house, Bin Laden was preparing Hamza to replace him as the terror outfit’s leader. Later on, Hamza was assumed to have donned the role of a deputy to the Alqaeda’s current chief, Al-Zawahiri.The United Nations Security Council reported that the deteriorating health of Al-Zawahiri has raised doubts about the global terrorist organisation’s succession.Pakistan’s war on terrorPakistan has often been accused of supporting terrorists in Afghanistan including the Al-Qaeda. Yesterday, the terror watchdog Financial Action Task Force’s (FATF) Asia Pacific Group placed Pakistan in its “enhanced expedited follow-up list”.The list, which is believed to be similar to be blacklisted, APG found the country non-complaint to 32 of the 40 parameters on money-laundering and terror financing.The announcement came a day after Prime Minister Imran Khan said that 40 different militant groups were operating in Pakistan when the country joined US war on terror after the 9/11 attacks in 2001.”We were fighting the US war on terror. Pakistan has nothing to do with 9/11. Al-Qaeda was in Afghanistan. There were no militant Taliban in Pakistan. But we joined the US war. Unfortunately, when things went wrong, where I blame my government, we did not tell the US exactly the truth on the ground,” the Pakistani PM said as quoted by news agency PTI.However, India has accused Pakistan of its state-sponsor of promoting cross-border terrorism in the disputed Jammu and Kashmir region.Earlier this month, Indian intelligence reports stated Pakistan’s Inter-Services Intelligence (ISI) has given terrorist group, Jaish-e-Mohammad (JeM) full permission for conducting suicide bomb attacks in the valley and cause as many casualties as they can, without worrying about “collateral damage”.US President Donald Trump in the middle of negotiating peace talks in Afghanistan with the Taliban and the Afghan government.The US government have stated that the withdrawal of US troops in a bid to end the 19-year war will be done over a period of time to ensure political stability and avoid security resurgence of Taliban’s state control in the region.last_img read more


UN warns of worsening humanitarian situation in Libya


first_imgUN warns of worsening humanitarian situation in LibyaFierce fighting for control of Libya’s capital that has already displaced tens of thousands of people threatens to bring a further worsening of humanitarian conditions, a senior UN official has warned.”As long as the situation continues, even if it just stagnates and continues like this, we can expect to see a continuing deterioration,” UN humanitarian coordinator for Libya Maria do Valle Ribeiro told AFP.Strongman Khalifa Haftar’s self-styled Libyan National Army (LNA) launched an offensive against Tripoli, the seat of the internationally recognised Government of National Accord (GNA), on 4 April.”When we see the use of air power, the indiscriminate shelling of densely populated areas, it is very difficult to be optimistic,” do Valle Ribeiro, who is also the deputy UN envoy to Libya, said late Sunday.She was speaking after air raids by the LNA on Tripoli on Saturday killed four people and wounded 20 others, according to the GNA.”We continue to call for a respect of civilians, we continue to call for humanitarian pauses and most of all we continue to hope that the situation can return to a more peaceful settlement of the crisis,” she said.The fighting has killed at least 278 people and wounded more than 1,300, according to a toll released Wednesday by the World Health Organization.It has also forced 41,000 people to flee combat areas around Tripoli, do Valle Ribeiro said, while many remain trapped and in need of humanitarian assistance.Migrants at riskAmong the most vulnerable are about 3,500 migrants and refugees held in detention centres near the combat zone who are at “risk”, the UN official said.She said that 800 considered most in danger had been evacuated, after the UN and rights groups said gunmen attacked a detention centre south of Tripoli last week.Doctors Without Borders (MSF) said several migrants and refugees were shot and wounded in the attack.Libya has been mired in chaos since the NATO-backed uprising that deposed and killed dictator Moamer Kadhafi in 2011.People smugglers have taken advantage of the lawlessness, ferrying mostly sub-Saharan Africans from Libyan shores to Europe.According to the International Organization for Migration some 6,000 migrants are held in official detention centres in Libya. Hundreds more are held by armed groups elsewhere in the war-hit country.On Sunday Pope Francis called for “humanitarian corridors” to be opened to evacuate them.The UN official also voiced concern over a breakdown in basic services, including electricity and water supplies, and said more relief funds were needed for Libya.”We appealed for an additional 10.2 million (dollars) which doesn’t cover all that we foresee… but it covers at least the essential response for the first three, four weeks,” she said.During the first week of fighting, she said, “over a million schoolbooks” that were stored in a warehouse of the ministry of education were destroyed when the compound was hit.”Symbolically, it says a lot about the impact of such strife and clashes on not just the immediate survival of people but on the future of Tripoli children.”last_img read more

Scientists go to great lengths to extend superlow friction


first_img Citation: Scientists go to great lengths to extend superlow friction (2015, February 13) retrieved 18 August 2019 from https://phys.org/news/2015-02-scientists-great-lengths-superlow-friction.html Researchers investigated the superlow friction of the chain structures above. They found that superlubricity can theoretically hold for tens of cemtimeters and disappears above a critical chain length, which depends on a material’s intrinsic properties. Credit: Ma, et al. ©2015 American Physical Society In the new study published in Physical Review Letters, researchers Ming Ma, et al., have theoretically investigated the maximum length of a chain of particles that exhibits superlubricity. Their model shows that this critical length depends on the experimental parameters and the material’s properties, especially its stiffness. For very stiff materials, such as carbon nanotubes, the scientists found that superlubricity may hold for up to tens of centimeters, after which it abruptly disappears. “These results indicate an avenue for achieving superlow friction at the macroscale, and can potentially aid in the rational design of superlubric materials for nanomechanical applications,” Michael Urbakh, a professor at Tel Aviv University and one of the study’s lead authors, told Phys.org.As the scientists explain, superlow friction relies on a special arrangement of atoms on a material’s surface. In graphite, for instance, the surface atoms have a bumpy hexagonal arrangement like egg cartons/boxes. In certain orientations, two surfaces of graphite can mesh in such a way that the “bumps” can slide past one other effortlessly, and friction drops to almost zero. In contrast, when the same pieces of graphite are slightly rotated with respect to each other, their surface atoms can no longer easily slide, and the materials exhibit the familiar effects of friction. This kind of change in geometrical configuration can explain the abrupt transition between the frictionless and friction regimes in the researchers’ models. A shorter nanotube, or chain, exhibits superlubricity because its particles are mismatched, or incommensurate, with the underlying substrate atoms. Since the atoms avoid interlocking with each other, the chain easily slides on the surface. But for a longer chain, a mechanical instability triggers lattice matching at the chain’s leading edge. As a result, the particles become in registry, or commensurate, with the atoms in the substrate lattice, and friction suddenly increases.The researchers’ simulations also revealed that the critical chain length forms a sharp boundary between two phases based on interparticle distance: the distance between particles is smaller in the shorter chain than in the longer chain. At exactly the critical length, an abrupt jump in this distance occurs, along with the abrupt jump in friction. By better understanding superlubricity and its limits, the researchers hope to extend the effect to as large a scale as possible. Superlubricity could prove very useful for designing nanoscale systems with low wear and tear, and it could be even more useful if it could be extended to larger scales. “The challenge here is to scale up the size of the sliding objects without losing the perfect egg-box geometry necessary for superlubricity,” said coauthor Andrea Vanossi at the CNR-IOM Democritos National Simulation Center and the International School for Advanced Studies (SISSA), both in Trieste, Italy. “Normally, as the size of the objects grows, defects and imperfections comes into play. Only recently, thanks to the impressive advances in the synthesis techniques, has it been possible to produce defect-free, atomically perfect elongated nanostructures such as carbon nanotubes, graphene nanoribbons, and conjugated polymers. Once it is possible to have two large-scale, geometrically perfect surfaces rub against each other without friction, and to apply this material as a coating to ball bearings and moving machine parts, there will be huge savings ahead in the areas of energy, resource consumption, and maintenance.”The researchers are currently working to expand their approach to understand mechanisms limiting superlow friction between 3D materials. © 2015 Phys.org (Phys.org)—When nanosized pieces of graphite slide against each other, there can be virtually no friction between them. For many years, superlow friction, or “superlubricity,” was known to exist only on the nanoscale. Then in 2012, scientists first demonstrated superlubricity beyond the nanoscale when they discovered the phenomenon in micrometer-sized graphite. Building on this and related research, scientists in a new study have now theoretically shown that superlow friction could extend to lengths of tens of centimeters.
