A new World Bank Group report finds that India set the pace for regulatory reform in South Asia in 2013/14 India with 20 — the region’s largest reforms during the period.India was followed by Sri Lanka with 16 reforms while three countries — Bangladesh, Nepal, and Pakistan — focused their efforts on adopting modern electronic systems to facilitate business activity.The Doing Business 2015: Going Beyond Efficiency report released on Wednesday found that four of eight economies in South Asia implemented at least one regulatory reform making it easier for local entrepreneurs to do business in 2013/14.”Doing business is easier in economies with administrative efficiency and strong regulatory protections,” said Rita Ramalho, Doing Business report lead author, World Bank Group.The report noted that in India a little over a decade ago, an entrepreneur seeking a loan to grow his business would have had little luck, because financial institutions lacked access to information systems to assess creditworthiness.”Today, thanks to the creation and expansion of a national credit bureau offering credit scores and coverage on par with those in some high-income economies, a small business in India with a good financial history is more likely to get credit and hire more workers,” it said.Three of India’s regulatory reforms benefiting local entrepreneurs were in the areas of starting a business, getting electricity, and protecting minority investors, including through the adoption of the new Companies Act of 2013.India made starting a business easier by considerably reducing the registration fees, but also made it more difficult by introducing a requirement to file a declaration before the commencement of business operations, the report said.These changes apply to both Delhi and Mumbai. In addition, the electricity utility in Mumbai made getting electricity less costly by reducing the security deposit for a new connection.Finally, India strengthened minority investor protections by requiring greater disclosure of conflicts of interest by board members, increasing the remedies available in case of prejudicial related-party transactions, the report said.It also introduced additional safeguards for shareholders of privately held companies. This reform applies to both Delhi and Mumbai.This year, for the first time, Doing Business collected data for a second city in economies with a population of more than 100 million.In India, it now analyses business regulations in Delhi and Mumbai; in Bangladesh, in Chittagong and Dhaka; and in Pakistan, in Lahore and Karachi.The report covering 189 economies worldwide, found that Singapore tops the global ranking on the ease of doing business.Joining it on the list of the top 10 economies with the most business-friendly regulatory environments are New Zealand; Hong Kong SAR, China; Denmark; the Republic of Korea; Norway; the United States; the United Kingdom; Finland; and Australia.
By Mark F. Gray, Special to the AFROA rainbow covered the skies following the game-stopping thunderstorms signaling a smile from the heavens, when Maryland and Texas returned to play after an unexpected weather delay in the fourth quarter at Fed Ex Field. Perhaps it was the presence of the late Jordan McNair who needed to give the Terps a lift after they had blown a 22 point lead on an emotional day where his teammates remembered him from start to finish.McNair, the offensive lineman who passed away from heat stroke in June, was honored by his teammates with #79 decals on their helmets, a moment of silence with his image on the jumbotron, and by lining up with only 10 players for the game’s opening play. The late lineman may have been the intangible they needed to win.Jordan McNair was remembered by fans and teammates during a pregame moment of silence before their season opening game vs. Texas at FedEx Field. (Photo by Mark Gray)Maryland is playing for more than wins and losses this season, they are playing for McNair. Emotion can take teams a long way in sports and perhaps this was the start of a special season in College Park. The Terps had several chances to give in but ultimately pushed through a series of challenges that may have broken one of their lesser teams to beat Texas 34-29 for the second consecutive year on September 1.“We just stayed together which has been our motto through everything that’s happened,” said wide receiver Taivon Jacobs during the postgame press conference. “Everybody in our building just packed our parachute and stuck together.”Any doubts that Maryland was up to this emotional challenge was put to bed on their first drive. The Terps’ march downfield was choreographed better than the performance by their band. With Kasim Hill starting at quarterback for the first time since his season ended last year in Austin the offense was almost flawless.Maryland football players honored his memory with his jersey on the field after their 34-29 victory over Texas at FedEx Field. (Photo by Mark Gray)“Its been a long time since we played a football game and it was good just to be back out on the field with your brothers,” said Hill.Maryland’s freshmen were massive. The neophyte Terps contributed to every score. Jeshaun Jones, from D.C.’s Friendship Collegiate high school, was the star. He busted through the Texas defense for 28 yards and the game’s first touchdown to cap their opening drive. Jones also went deep against the Longhorn secondary for a 65-yard scoring reception. In the second quarter, Jones converted a jet sweep option by connecting with Tavion Jacobs for a 20-yard touchdown pass to give Maryland its biggest lead at 24-7.Jones scored three times in the first half placing himself in elite company. He became the first college player to score on a rush, reception and pass in his first game in 20 years.The Longhorns used their uptempo, offense to change the game’s momentum and took the lead. Texas scored 22 unanswered points behind sophomore quarterback Sam Ehlinger. Texas’ defense also stopped Maryland’s Jake Funk in the end zone for a safety which closed the gap to 24-22 at halftime. Ehlinger found Collin Johnson in the endzone on for a touchdown then Kyle Porter’s two-yard score gave Texas its only lead.Interim head coach Matt Canada’s leadership was tested also after both teams went to the locker rooms as the mini monsoon hit. He first had to re-establish the Terps offense after overcoming an 86 minute weather delay and conservative play calling that kept Texas alive. The Terps went 75 yards in just under five minutes for the game’s final and decisive score while their defense produced three fourth quarter turnovers to seal the game.The adversity of their offseason seems to have prepared them for challenges of the season to come at least for one big game.
Digitally programmable perovskite nanowire-block copolymer composites Citation: Ultra-Fast Quantum-Dot Information Storage (2008, March 21) retrieved 18 August 2019 from https://phys.org/news/2008-03-ultra-fast-quantum-dot-storage.html Explore further This document is subject to copyright.

The information-storage market is dominated by two main types: Flash memory, used in memory sticks and cell phones, and dynamic random access memory (DRAM), which is the main memory in a personal computer. Both types have their advantages and disadvantages, but a new type of memory, based on tiny atom clusters, called quantum dots, may soon displace both of them. In research published in the March 4, 2008, online edition of Applied Physics Letters, scientists from the Technical University of Berlin, in Germany, and Istanbul University, in Turkey, describe how they created a type of quantum-dot-based memory device that can save information at speeds of only a few nanoseconds (billionths of a second).The paper’s lead author, Technical University of Berlin scientist Martin Geller, explained to PhysOrg.com, “Flash memory, which is today’s market-driver in the semiconductor industry, and which everybody knows from memory sticks, digital cameras, and mp3-players, has a slow write time. The semiconductor industry is seeking faster Flash memories, but hasn’t found an ultimate solution yet. Our quantum-dot-based memory may provide long storage time without power consumption of Flash memory, as wells as a fast write time and better scalability to real-life devices.”To be fair, the other established predecessor of quantum-dot memory, DRAM, does have some excellent qualities. It offers very fast information-access times—under 20 nanoseconds—and the information can be repeatedly written and rewritten on a DRAM; it has excellent so-called endurance. But a DRAM device has a big disadvantage: It is volatile, meaning the information has to be refreshed every ten milliseconds to be maintained, also resulting in a high power consumption.“The very first prototype of our new quantum-dot-based memory scheme is already almost as fast as DRAM,” said Andreas Marent, a physicist at the Technical University of Berlin who took part in the research. “And in contrast to DRAM or Flash, the physical characteristics of quantum dots limit the write time to the picosecond, or trillionth of a second, range. That means a better device prototype should be more than 100 times faster than today’s DRAM.”The prototype consists of quantum dots of indium arsenide (InAs), a compound of the metals indium and arsenic, embedded in a layer of gallium arsenide (GaAs; gallium is also a metal). The GaAs layer is “p-doped,” which means it contains impurity atoms that impart it with excess free positively charge called holes. This InAs/GaAs structure is topped with a layer of “n-doped” GaAs, which contains extra electrons. Altogether, the structure is a p-n diode, an electrical device that allows current to flow only in one direction.When a voltage is applied across this structure, the quantum dots become charged, which allows them to store bits of information, i.e. “0” or “1” values. Whether the quantum dots represent a 0 or 1 depends on the capacitance of the diode—how much charge it is holding. A larger capacitance indicates the quantum dots do not hold much positive charge, which equates to a “0.” A smaller capacitance means that the dots are filled with holes, representing a “1.”Geller, Marent, and their colleagues say that the write times of their quantum-dot schemes are currently limited by the experimental setup and certain physical characteristics of the memory structure. In the future, after they make improvements to the structure, they expect that write times faster than 1 nanosecond may be possible. Even picoseconds seem possible, since the structure’s physical limitation is in that range.Said Prof. Dieter Bimberg, who is the group’s leader at the Technical University of Berlin and co-author on the paper, “Our results and patents demonstrate that quantum dots like these we are studying might, in just a few years, revolutionize semiconductor memory.”Citation: Appl.

Or is it just a very big rock? © 2016 Phys.org Explore further Citation: Archaeologist sees Bosnia stone sphere as the most massive in Europe (2016, April 17) retrieved 18 August 2019 from https://phys.org/news/2016-04-archaeologist-bosnia-stone-sphere-massive.html Prehistoric rock art engraving discovered in Brecon Beacons A stone ball in Podubravlje village near Zavidovici, Bosnia and Herzegovina was seen earlier this month, in the ground, in a forest.What can it tell us? Archaeologist Sam Osmanagich, who called his Bosnian stone ball the most massive in Europe, has some interesting answers.”I’ve been researching prehistoric stone ball phenomenon for 15 years,” he blogged last month.”By the mid of March 2016, it became obvious that the most massive stone ball in Europe has been discovered. Name of the location is village Podubravlje.”He said actually less than half of the ball is uncovered. “Preliminary results show the radius to be between 1.2 – 1.5 meters. Materials have not been analyzed yet. However, brown and red color of the ball point to very high content of the iron. So, the density has to be very high, close to the iron which is 7,8 kg/m3. If we take value of only 5 kg/c.c. we have all the elements for the preliminary calculation of the mass. Mass comes to be over 30 tons!”Why does he view this discovery as significant? “First, it would be another proof that Southern Europe, Balkan and Bosnia in particular, were home for advanced civilizations from distant past and we have no written records about them. Secondly, they had high technology, different than ours. Finally, they knew the power of geometrical shapes, because the sphere is one of the most powerful shapes along with pyramidal and conical shapes. No wonder, that pyramids and tumulus phenomena can also be found in Bosnia.”News.com.au said Osmanagich had examined granite stone balls in southern Costa Rica, volcanic stone spheres in western Mexico and Easter Island, and then turned his attention to Bosnia.If the huge stone in Bosnia is found to be hewn by human hands, it would be the largest man-made stone ball ever found – twice as heavy as the Costa Rican ones, said MailOnline.Do other experts see the rock formation as proof of an ancient civilization which thrived there? Voice of America reported that some scientists said the rock was likely a natural formation and not a human construct.Experts were quoted in MailOnline as saying they believed the boulder was not man made. A lecturer at the University of Manchester School of Earth, Atmospheric and Environmental Sciences told MailOnline that the spherical stone may be an example of concretion. This is when a compact mass of rock is formed by the precipitation of natural mineral cement within the spaces between sediment grains. The result is often spherical in shape, with the process forming the famed Koutu boulders in New Zealand. Experts at the Geological Society, according to MailOnline, said the round shape of the rock could come from spheroidal weathering. This is a type of weathering affecting jointed bedrock. The result is formation of concentric or spherical layers of highly decayed rock. This document is subject to copyright.
