Gov’t not Reliant on Mega Projects – Dr. Phillips

first_imgMinister of Finance and Planning, Dr. the Hon. Peter Phillips, says the Government is not relying solely on mega projects to grow the economy, but is also investing in areas such as small and micro businesses, as these are important in achieving economic growth. Dr. Phillips told journalists at a post budget news conference at the Office of the Prime Minister, on Friday (May 3), that the Government has committed significant sums to the small and micro business sector through various initiatives in the budget. These he noted include: $2 billion, through the Development Bank of Jamaica (DBJ) and the US$20 million to be used in facilitating the construction of Information and Communications Technology (ICT) centres, from which these businesses will also benefit. He further noted that the sector will also benefit from commitments in Agro Parks as well as from sustained low interest rates through fiscal consolidation. The latter, he said, would “provide the incentives to the hundreds of thousands of small medium and large investors to get into the act of producing.” Dr. Phillips announced on April 18, as he opened the 2013/14 Budget Debate in the House of Representatives, that the DBJ would commit $2 billion to the micro and small business sector this year, to ensure that some 12,250 enterprises can gain access to credit through its network of intermediaries. This is a significant increase over the $650 million that was disbursed in 850 loans in the last financial year. He had also announced that the DBJ would help to increase the number of institutions that are extending credit to micro and small enterprises. Contact Andrea Brahamlast_img read more

Serena Williams Announces Engagement to Reddit Cofounder Alexis Ohanian

Throughout the tennis pro’s year, Ohanian has been her biggest supporter, frequently posting messages of support online. When Williams tied Steffi Graff’s Grand Slam record at Wimbledon this past summer, Ohanian shared how proud he was on Instagram. Ohanian, 33, also commented on the Reddit post, which was accompanied by a graphic showing the proposal. He wrote, “And you made me the happiest man on the planet.” Additionally, he confirmed the news on his Facebook page by sharing his fiancée’s post and commenting, “She said yes.”The newly engaged couple, who began dating in Oct. 2015, are notoriously private, but Williams has occasionally mentioned Ohanian on social media. Most recently, the Olympian shared an image of the couple in costume on Nov. 28. Serena Wiliams and Alexis Ohanian (@serenawilliams Instagram/@alexisohanian Twitter)Tennis star Serena Williams is engaged to her boyfriend of a year, Alexis Ohanian. The 22-time Grand Slam champion announced the news on her official Reddit page, marking a very public showing for the very private couple.Williams, 35, detailed the story on Thursday, Dec. 29, explaining that she and the Reddit co-founder took a trip to Rome, where they first met. read more

Quantum thermal transistor can control heat currents

The content is provided for information purposes only. World’s first successful use of an electric circuit to compensate for distortions in electric signals due to heat The researchers, Karl Joulain et al., at the University of Poitiers and CNRS in France, have published a paper on the quantum thermal transistor in a recent issue of Physical Review Letters.”To manage electricity, one uses electronic diodes, transistor and amplifiers,” Joulain told Phys.org. “We would like to do the same thing with thermal currents. We would like to make logical thermal circuits in the same way electronic thermal circuits have been designed. In this way, wasted heat could be guided, switched on or off, amplified or modulated.”Although this is not the first thermal transistor, it is the first that is made of quantum objects. Other thermal transistors are made with macroscopic materials, such as solids or phase change materials. The new quantum thermal transistor consists of three two-level systems, meaning they have two states. These systems can be implemented as spins, where each spin can be in either the up state or the down state. Any one of these spin systems can control the heat current flowing through the other two. The researchers theoretically demonstrated that the thermal current can be controlled, modulated, and amplified by a sufficiently large amount so that it can switch the spins between their two states, producing a transistor effect. The transistor could be used to control thermal currents in a variety of nanostructures made of quantum objects. In the future, for instance, the device could in principle be fabricated with quantum dots embedded in nanoparticles.”My future research plans are to optimize the device and of course to find collaborations to make the experiment at the quantum level,” Joulain said. The quantum thermal transistor consists of three two-level systems, which can be implemented as spins with an up and a down state. Any one of these systems can control the heat current that flows to the other two, resulting in switching their spins. Credit: Joulain et al. ©2016 American Physical Society (Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in applications that recycle waste heat that has been harvested from power stations and other energy systems. Currently, there are methods for transporting and guiding this heat, but not for controlling, amplifying, and switching the heat on and off, as the quantum thermal transistor can do.
