Cushwa Center to award Hesburgh Research Travel Grants

first_imgThe Cushwa Center for the Study of American Catholicism announced its new Rev. Theodore M. Hesburgh Research Travel Grants program, a three-year initiative to help support research projects that consider archival information pertaining to University President Emeritus Fr. Theodore Hesburgh, according to a University press release.According to the Center’s website, the grants will help cover travel and lodging costs for researchers traveling to the Notre Dame Archives to access information about the life and legacy of Hesburgh. This opportunity is open to researchers of any academic discipline. Applicants must clearly demonstrate how their projects will relate to Hesburgh.The Cushwa Center offers a number of annual research grants, designed assist scholars who wish to use Notre Dame’s archival collection in Catholic Americana.Hesburgh served as president of the University for 35 years from 1952 through 1987 and died last February at the age of 97. Over the course of his life, Hesburgh was an influential figure in higher education, Catholicism, the civil rights movement and international affairs. During his time as president of the University, he doubled enrollment and allowed women to attend Notre Dame.“Hesburgh’s unique perspective and prodigious contributions stand to inform and enrich a broad range of narratives in American social, religious and political history, as well as ongoing discussions in public policy, philosophy of education, peace studies and theology,” according to the Center’s application page.The Notre Dame Archives, housed in Hesburgh Library, contains primary source documents about the work and life of Hesburgh. According to the website, Hesburgh often sent his papers to the Archives once they were no longer needed for his ongoing work. After his time as University president, he sent the files representing his years in office in addition to many documents from his outside activities.“The Cushwa Center has a longstanding tradition of providing financial support to scholars who are conducting research into the Catholic history of the United States,” Kathleen Sprows Cummings, director of the Center, said in the press release. “Through the creation of the Hesburgh Research Travel Grants, we are looking forward to making new connections with scholars of education, peace studies, political science, policy studies, theology and other fields.“Thanks to this new funding opportunity, Father Ted continues to act as a catalyst and a connector, drawing people from different disciplines and perspectives together to advance our understanding of the world.”The deadline to apply for the first rounds of grants is April 1. Applicants must submit a description of their project and how it pertains to Hesburgh, as well as a proposed budget of estimated travel, lodging and research costs. Grants will be awarded twice yearly, each April 1 and Oct. 1, through 2018.Tags: Father Hesburgh, ND archives, research grants, Rev. Theodore M. Hesburgh Research Travel Grantslast_img read more

Faster through the curves on JR-Central

first_imgINTRO: Since Japanese National Railways was divided into separate companies in 1987, JR-Central has put into service around 600 new vehicles for its 1067mm gauge network that carries over half a million passengers a day. Tilting trains have helped cut journey times on key routesBYLINE: Kazuhiro YoshikawaManager, Rolling Stock DepartmentConventional Lines Operations DivisionCentral Japan Railway CoIN THE 10 YEARS since Japanese National Railways was broken up, JR-Central has worked hard to develop rolling stock for its 1067mm gauge lines that will lift comfort standards, reduce operating costs and permit faster journey times. Running on 12 routes serving central Japan to cities such as Nagoya and Shizuoka, the JR-Central narrow gauge fleet comprises around 1500 vehicles. Of these, 1130 are EMU cars and 240 are DMU vehicles used on the 490route-km of non-electrified track. Every day around 520000 people ride JR-Central’s narrow gauge trains.The first type of train developed independently by JR-Central was the Series 85 Kiha DMU. This was launched on express services in 1989.Powered by two British 350hp engines giving balancing speeds in excess of 100 km/h on gradients of up to 2%, Series 85 had a major impact on Japanese DMU design. The choice of engine was central to the Series 85 development process; power plants from many different countries were assessed against the criteria of high performance and good fuel economy. To combine a maximum speed of 120 km/h with adequate acceleration and deceleration on medium-speed sections in mountainous territory, a torque converter was used to increase the number of gear stages. Power control and gear changing is managed by computer.Right from the start of development work, careful attention was paid to the bodyshell and interior design rather than adopting the latest fashionable shapes and colour schemes. A stainless steel body combining attractive lines with easy maintenance was eventually chosen.Introduction of the Series 85 DMU brought Hida Limited Express journey times down by 41min to 2h 9min, and cut Nanki Limited Express timings by 51min to 3h 22min. Thanks to the shorter timings, traffic on these routes has been steadily increasing.Lower maintenance costsThe Series 373 Limited Express EMU was introduced in 1995, following development work that focused on reducing maintenance costs. The Series 373 is a three-car EMU, to which extra cars can be added if required. A total fleet of 42 Series 373 cars replaced 57 older vehicles, with drive maintenance costs reduced by the adoption of a format of one motor car and two trailers.Class 373 has a monitoring system for equipment that was specified with low maintenance costs in mind. This ensures that the performance of equipment on board the train is checked whenever the train is in use; it monitors the VVVF inverter control and brushless traction motors, the inverter-based auxiliary power supply, contactless master controllers, scroll air compressors, vacuum toilets and electric water pumps.The bogies have been designed so that they are compatible with automated robots.These design features have reduced maintenance costs by 50% compared with earlier types of train. Future rolling stock development is likely to pay even closer attention to lower vehicle life cycle costs.Second generation tilting trainsDeveloped to replace the Series 381, Japan’s first train incorporating passive tilt technology introduced in 1973, the Series 383 EMU first entered service in December 1996. This 1·5 kV DC tilting train was developed to provide faster, more comfortable services, and to be easier to operate.Higher speeds through curves remains an important goal for the railways in Japan, which is a mountainous country. The Class 381 was able to operate at maximum speed on only 16% of the 175 km Nagoya – Shiojiri section of the Chuo line, as 58% of the route is subject to curve-related speed restrictions.Work began in 1989 on improving speeds through curves, concentrating on rail load forces, ride quality and stability in side winds. The fruits of the development programme applied to the Class 383 included a lightweight body with a low centre of gravity, new self-steering bogies and active body tilting.Self-steering bogieJR-Central developed and introduced a self-steering bogie based on the theories of Yoshihiro Suda, an associate professor at Tokyo University. The support stiffness of the leading axle has been made softer than that of the trailing axle, reducing the angle of attack between wheel and rail in curves and cutting load forces applied to the rail. The average reduction in lateral force, which tends to be high on curves with a radius of less than 500m, is around 30%.The support stiffness of the axles in each Series 383 car was initially configured in a soft-hard-soft-hard arrangement, with the first soft axle leading and the configuration reversed when the train changed direction. During test runs with the prototype in 1994, we found that there was no need to make the third axle soft when bolsterless air sprung bogies were used. The axle stiffness configuration was accordingly modified to soft-hard-hard-soft, removing the need to switch the configuration when the train reverses.Designed with a low centre of gravity, the Series 381’s passive body tilting works by centrifugal force. Ride comfort was impaired by the delay in tilting when the train entered a curve and the ’overtilt’ experienced on leaving it.Active tiltSeries 383 has active tilt, with the body smoothly angled by air cylinders following the instructions of an on-board computer programmed with track data (above). The roller guides supporting the body on the Series 381 were replaced on the Series 383 by bearing guides. Series 383 has a maximum speed of 130 km/h and the fastest curving speed of any Japanese narrow gauge train. It can negotiate a 600m radius at 125 km/h, 35 km/h above the usual speed for such a curve. It was put into service on the Shinano Limited Express in December 1996 and has cut 10min from the Nagoya – Nagano run. Tilting services operated with Series 383 EMUs are expected to play an important part in transporting people to and from the 1998 Winter Olympics in Nagano. oCAPTION: Kiha 85 DMU in use on Limited Express services is powered by Cummins enginesCAPTION: Series 373 three-car EMUs have made an important contribution to cutting JR-Central’s maintenance costslast_img read more

Santos leaves Arsenal

first_img The 30-year-old Brazil international returns to the club where he had a short period on loan earlier in his career after spending two seasons with Arsenal. He joined the Gunners from Turkish side Fenerbahce in August 2011 and made 33 appearances in total with Arsene Wenger’s side. Arsenal left-back Andre Santos has joined Brazilian side Flamengo in a permanent deal, the Barclays Premier League club have announced on their website. The attacking full-back, who cost Arsenal £6.8million, was sidelined by a knee injury for a spell during his first campaign at the Emirates Stadium, during which he made 21 appearances in all competitions, scoring three goals. Last season he played 12 times for the north London outfit before falling down the pecking order behind England left-back Kieran Gibbs. Then, following the £8.5million signing of Spaniard Nacho Monreal on the final day of January’s transfer window, he joined Brazilian side Gremio on loan for the rest of the 2012/13 campaign. He has now returned to the Campeonato Brasileiro with Flamengo, who he played 22 matches for while on loan from Figueirense during the 2005/06 season. Santos has also played for Corinthians and Atletico Mineiro in his homeland. Arsenal said in a statement on their website: “Everybody at Arsenal would like to thank Andre for his contribution to the club and wish him well for his future career.” center_img Press Associationlast_img read more
