Lawrence is one of three Clemson players suspended by the NCAA for a failed drug test before the team’s national semifinal against Notre Dame.Lawrence reportedly tested positive for a banned substance.He, tight end Braden Galloway and offensive lineman Zach Giella are in the process of appealing the NCAA’s decision, but it looks like the process is still ongoing.Because of that, all three won’t be able to play.Clemson DT Dexter Lawrence will not play in the CFP championship. pic.twitter.com/QyUGtNhaUX— Ralph D. Russo (@ralphDrussoAP) January 3, 2019Lawrence finished the season with 44 tackles (7.5 for loss), 15 quarterback pressures, three pass breakups and 1.5 sacks in 13 games.Clemson and Alabama will play for the national championship at Levi’s Stadium in Santa Clara, Calif. on Monday night.Kickoff is set for 8 p.m. ET on ESPN.last_img read more

MTU, Fairplay to Test MTU SCR System in Real Life

first_imgzoom On of the most difficult tasks for maritime engineers is posed by the upcoming emission regulations pushing for cleaner and more efficient engines compliant with IMO Tier III/IV NOx emission  standards, Dr. Ulrich Dohle,President and CEO of the Rolls-Royce Power Systems subsidiary MTU Friedrichshafen GmbH said during a press briefing at the SMM.Mr Dohle said that MTU and Fairplay Towage are going to test an MTU diesel genset with SCR exhaust aftertreatment in real life. The first test will take place in two years time and will involve a harbor tug in order to verify compliance with IMO Tier III emission requirements that come into force as of 2016. The nitrogen oxide (NOx) emissions are expected to be reduced by 90% in comparison with the IMO Tier I regulation that was introduced in 2000.“This is one of the world’s first tests of high-speed diesel engines equipped with an SCR system designed to meet the NOx levels required by IMO Tier III,” said Dr. Michael Haidinger, Chief Sales Officer of Rolls-Royce Power Systems. “We are proud to have this opportunity to demonstrate to our customers a pre-series and cost-saving solution.”The new Fairplay tug featuring a bollard pull of 90 tons is currently being built at the Spanish shipyard Astilleros Armon and is scheduled to go into service in the Port of Rotterdam as of 2015.MTU is supplying the two main 16V 4000 M63L propulsion engines, each with 2,000 kW, a 16-cylinder 4000 M23F diesel genset rated at 1,520 kW, and the SCR system. The exhaust aftertreatment system, with selective catalytic reduction (SCR) technology, is connected to the diesel genset. As with modern commercial vehicle drive systems, an aqueous urea solution reacts with the nitrogen oxides in the exhaust gas to neutralize them.The tests on the Fairplay tug, which will run continuously for 10,000 hours, are designed to enable MTU to get ready for the series solution for IMO Tier III marine engines. As of 2016, newly built ships that operate in Emission Control Areas (ECA) in North American coastal waters and in the U.S. Caribbean will have to comply with the NO x limits specified in the IMO Tier III emission standards and the MARPOL Annex VI regulations of the International Maritime Organization.“MTU is well-prepared for IMO Tier III, be it with SCR exhaust aftertreatment systems for diesel engines or with gas engines,” explains Dr. Michael Haidinger, Chief Sales Officer at Rolls-Royce Power Systems.The Rolls-Royce brand MTU will be presenting its propulsion and systems portfolio for yachts, merchant vessels and navy ships at the international maritime trade fair SMM from 9 12 September, 2014. MTU will also be showcasing variable-speed gensets for yacht and merchant fleet applications.

Namal rubbishes allegations

Parliamentarian Namal Rajapaksa has rubbished the allegations raised against him over the break-in at the Bambalapitiya residence of journalist Mandana Ismail Abeywickrema.Some websites had alleged that the men who forced their way into Abeywickrema’s house had been looking for some files involving MP Namal Rajapaksa. The United Nations High Commissioner for Human Rights Navanethem (Navi) Pillay commenced her weeklong visit on the 25th of August to Sri Lanka which is on the Reporters Without Borders lists of “countries under surveillance” and ranked 162nd out of 179 countries in the 2013 Reporters Without Borders press freedom index. (Colombo Gazette) However MP Namal Rajapaksa denied he had any involvement in the incident and that an intelligent person would not believe such rumours. “The pen is mightier than the sword. Unfortunately one can write any fictitious story and spread any rumour but it is for the intelligent mind to believe so otherwise,” MP Rajapaksa told the Colombo Gazette.Meanwhile Reporters Without Borders (RSF) and its partner organization, Journalists for Democracy in Sri Lanka (JDS) called upon the head of United Nations human rights body visiting Sri Lanka to be uncompromising in her search for accountability on grave crimes committed against journalists and media freedom including on the incident involving journalist Mandana Ismail Abeywickrema. While the police insist that the men were part of a robber gang, UNP leader Ranil Wickremesinghe and others have been quoted as saying it was not a mere robbery attempt. read more

ABB gearless conveyor drive for wider range of motors

first_imgInnovative solution fulfills eco design requirements, improves reliability, saves energy costs and reduces overall maintenance costs for mining operators.ABB’s innovative gearless conveyor drive is available for use on a wider range of conveyor systems. Already proven on larger motors, the newest drive is designed for medium power range motors (1 to 3 MW per motor) to make this technology economically feasible for a broader range of conveyor systems, including the use on mobile equipment in mining operations. The new solution can be applied for both greenfield and brownfield systems, and significantly decreases the cost threshold for gearless conveyor technology.Fewer parts and new motor technology increase the reliability and efficiency of the overall conveyor system. A permanent magnet motor specifically designed for mining applications is a core element of this system that contributes to its reliability and ability to perform in the most challenging environments.The gearless conveyor drive system eliminates the gearbox from the drive. This reduces the number of main wear parts, so less maintenance is needed, and lengthens the lifespan of the equipment. The expected lifespan for the drive train increases by more than 10 years when compared to traditional geared systems, to a projected in service life of 25 years.Other advantages include a considerable reduction in the drive system’s footprint, so it can be installed in smaller spaces, less weight, and a reduction in the instrumentation required to operate the system. The gearless drive design is also more energy efficient, requiring less power, and operates more quietly, thus reducing noise emissions.In July 2017, the pilot project of this solution was installed in collaboration with Lausitz Energie Bergbau AG (LEAG) in the open-pit lignite mine Jänschwalde, located close to Cottbus, Germany. The new gearless solution was installed on a high capacity (15.000 t/h) discharge conveyor of a bucket chain excavator in parallel with the existing geared drive. Both drives connect to the same pulley shaft to allow for exact benchmarking. The gearless solution has performed better in regard to dynamic accuracy and overall efficiency than the existing traditional solution.The operational data demonstrate the advantages of the gearless solution with less components .A gearless solution is more reliable (with a 50% lower failure rate) and requires less maintenance. It is meeting eco design and energy performance requirements according to international standards to support mine site’s environmental approvals or certification. The new drive also consumes 5% less energy than the other installed drive.“The interest of LEAG in this pilot project mainly lies in the expectations related to higher efficiency, lower wear and hence less expenses for repairs and maintenance,” said Peter Scholze, Head of Service Open Pit Mines, LEAG.  “These results were verified from measurements and analytics taken during operations in the past few weeks. At the same time, the project proves LEAG’s interest in a future-oriented and innovative technical approach. Thanks to the close cooperation between LEAG and ABB, the project could be finalized within a short period of time. Since commissioning has taken place, the drive has been running smoothly.”The onsite team was impressed with ABB’s quick and flawless project commissioning, The operations and maintenance team also found the new system to be easy to learn, understand, and use, without any major difference in operation or handling when compared with the existing systems/ technology.last_img read more
