Government defers scrap metal legislation to 2019

first_imgGovernment has deferred the deadline for bringing legislation to govern the scrap metal trade to the National Assembly, to next year.This was revealed during the second day of consideration of the Budget 2019 estimates when Business Minister Dominic Gaskin was questioned about allocations to various agencies under the Ministry.He was previously optimistic of bringing the scrap metal legislation to the House by this year end, following much back and forth after the trade was halted by Government.The ban was temporarily lifted in February 2017, after it was imposed in JuneBusiness Minister Dominic Gaskin2015. The Business Minister revealed in September that Government would be reopening the trade of scrap metal for three-month stints at a time until the relevant legislation was tabled. In June 2018, he had said that the new legislation was taken to the Cabinet and approved at that level. The next step, he had noted, would have been to approach the National Assembly.“Hopefully, before the end of the year, we will have a new legislation.  We will have a new software system that we are using, and we will have a Board of Directors to oversee the scrap metal unit, and I believe we’ll have something firm and solid in place to regulate the scrap metal industry,” Gaskin had told the media earlier this year.However, following that declaration, the legislation was finalised in the Attorney General’s Chambers and has since been awaiting passage in the National Assembly. Government had approved a restart of the scrap metal trade in Guyana during February 2017 after closing down the industry one year prior to that.The main reason for this was to allow exporters to ship out the existing stock over a limited period of three months, to ensure that there was no pile-up of these materials. However, in April 2018, after several months of delays, Government decided to reopen the trade to facilitate the clearance of some of the accumulated scrap metal across the country.While a date for the full resumption of the trade had not been announced, Gaskin had told this publication that the date depended on several important factors.The Minister disclosed that a meeting was held with exporters and dealers to introduce them to a new system that the Business Ministry was trying to implement.According to him, it is a software-based system that was specially designed to help the Ministry to monitor and regulate the trade once it resumed, creating a level playing field for all.Gaskin said the resumption of the trade would give the Ministry the opportunity to test the system to ensure that it was working and would also help to clear some of the accumulated scrap metal that has been legitimately acquired from some of the exporters or dealers’ yards.It was after a forensic audit conducted by the Scrap Metal Unit (SMU) that Government had removed the responsibility for the trade from the Central Housing and Planning Authority (CH&PA) to the Business Ministry.last_img read more

In Weyl semimetals, however, the electrons near the Weyl points form quasiparticles that, in a magnetic field, can contribute to heat conduction without transporting charge [1, 2]. This charge-less transport arises because the contribution of charge from two pairs of Weyl points cancel each other out (inset). Credit: APS/Alan Stonebraker A pair of researchers at the Hong Kong University of Science and Technology has found that a chiral zero sound (CZS) effect can be induced in Weyl semimetals. In their paper published in the journal Physical Review Letters, Zhida Song and Xi Dai describe their experiments with Weyl semimetals and what they found. © 2019 Science X Network , arXiv Weyl semimetals have only recently been discovered, though they were predicted to exist in 1929 by Herman Weyl. They are topological materials in which electronic excitations exhibit massless behavior. Prior research has shown that fermions that adhere to Weyl’s theorem exist as quasiparticles in some solids—those that have electron energy bands that cross at points close to the Fermi energy. Notably, they behave differently than electrons in metals—they exhibit the chiral magnetic effect. This effect is observed when a Weyl metal is exposed to a magnetic field—a current is generated where positive and negative particles move in parallel and anti-parallel to the magnetic field. In such situations, the flow of current is zero because the particles cancel each other out. This changes, however, when the semimetal is placed in a parallel electric current resulting in a quasiparticle flow—an effect known as the chiral anomaly. In this new effort, Song and Dai have shown that the chiral magnetic effect can also lead to a phenomenon called the chiral zero sound (CZS), a newly discovered heat transport mechanism that can be seen in Weyl semimetals. Zero sound comes about due to vibrations, but it is carried by the momentum distribution of electrons when they exist near the Fermi Level. The study reports that they have existed all along, occurring when researchers place a Weyl semimetal in a magnetic field—now, the researchers have observed them in action. They report that the effect contributes to the thermal conductivity of such materials. They also note that its velocity can be modulated by altering the magnetic field. And they note that the effect can be measured using a variety of techniques, such as employing pump and probe. They describe their discovery as a “completely new sound mode carried by Weyl fermions under a magnetic field.”last_img read more
