The division irto subject groups is borrowed from the biographical section of the "Encyclopedia of American History" with the addition of "Presidents" and includes fields in science, social science, arts and humanities, and public life. A person versatile in more than one field is categorized under the field which reflects his greatest achievement. Scientists who were more effective in the diffusion of knowledge than in original and creative work, appear in the tables as "Educators." Each bibliographic entry includes author, title, publisher, place and data of publication, and Library of Congress classification.

· R·I·T NEWSVol. 19, No. 8 & EVENTSDecember 17, 1987 Event Honors Horton, Benefits Future Scholars A gala testimonial dinner celebrating 25 years in Congress for U.S. Rep. Frank Horton has raised $500,000 for RIT scholarships. An estimated 1,200 people gathered at the Rochester Riverside Con vention Center, Friday, Dec. 11 , for the black-tie event. A bipartisan group of national politi cians, including President Reagan, corpo rate and civic leaders, and friends , offered tributes, accompanied by military bands, high school bands, bagpipers, a chamber quartet and the Glenn Miller and Roger Eckers orchestras. At the event, the Congressman an nounced the creation of The Frank Horton Endowed Scholarship Fund. He selected RIT to receive the scholarships established in his name and based on proceeds from the event. Individuals and corporations from Washington, D.C., and throughout the 29th Congressional District gave gifts ranging from $250 to $50,000 to honor Horton's quarter century of public service. "Creation of the RIT Horton Scholars program at RIT reflects my long-standing and deep interest in the economic develop ment of greater Rochester and RIT's role in providing business and industry with highly qualified graduates," Horton said. "Frank has a long history of support for RIT," said President M. Richard Rose. "He participated in the founding of the National Technical Institute for the Deaf and is a member of NTID's National Advisory Group. He supported the Insti tute·~ new Center for M icroelec-tronic ancl Computer Engineering and has applauded RIT's professional career programs, which impact on this country's productivity." Tribute festivities at the convention center included a video message from President Reagan, who said "Frank, you are a man of great personal conviction, and you demonstrate integrity and leadership second to none. -

Basic Principle A.C. generators or alternators (as they are DC generator usually called) operate on the same fundamental principles of electromagnetic induction as d.c. generators. They also consist of an armature winding and a magnetic field. But there is one important difference between the two. Whereas in d.c. generators, the armature rotates and the field system is stationary, the arrangement Single split ring commutator in alternators is just the reverse of it. In their case, standard construction consists of armature winding mounted on a stationary element called stator and field windings on a rotating element called rotor. The details of construction are shown in Fig. 37.1. Fig. 37.1 The stator consists of a cast-iron frame, which supports the armature core, having slots on its inner periphery for housing the armature conductors. The rotor is like a flywheel having alternate N and S poles fixed to its outer rim. -

E-mail address: kovalentek.ru Abstract RF DEMO-S reactor is a prototype of commercial fusion reactors for further generation. A blanket is the main element uit of the reactor design. The segment structure is the basis of the ceramic blanket. The segments mounting/dismounting operations are carried out through the vacuum vessel vertical port. The inboard/outboard blanket segment is the modules welded design, which are welded by back plate. The module contains the back plate, the first wall, lateral walls and breeding zone. The 9CrMoVNb steel is used as structural material. The module internal space formed by the first wall, lateral walls and back plate is used for breeding zone arrangement. The breeding zone design based upon the poloidal BIT (Breeder Inside Tube) concept. The beryllium is used as multi lier material and the lithium orthosilicate is used as breeder material. The helium at 0. 1 MPa is used as purge gas. The cooling is provided by helium at 10 MPa. -
Historical Loss Experiences in the Global Power Industry August 2014 Contents
MARSH RISK MANAGEMENT RESEARCH HISTORICAL LOSS EXPERIENCES IN THE GLOBAL POWER INDUSTRY AUGUST 2014 CONTENTS 1 INTRODUCTION 2 PART ONE: PRINCIPLES OF GENERATING ELECTRICITY 8 PART TWO: HISTORICAL LOSSES 48 CONCLUSION HISTORICAL LOSS EXPERIENCES IN THE GLOBAL POWER INDUSTRY ii marsh.com MARSH RISK MANAGEMENT RESEARCH INTRODUCTION At Marsh, our claims management and power industry experience enables us to present an accurate description of the types of events that commonly lead to insurance claims. To compile this study, we used data and an analysis of global trends that many power clients will already be acquainted with. The purpose of this document is to provide commentary on the world of power generation, the risks affecting that industry, and the importance of effective risk management in preventing or mitigating these risks. The report is divided into two parts: ȫ Part one provides a brief overview of some of the key technologies being used in power generation, including details of some areas that are either emergent or in the research-and-development stage at the time of writing. ȫ Part two features a narrative description of some of the historical loss experiences that have affected the power generation industry in recent years. It may be helpful to review this document along with the following recent Marsh Risk Management Research briefings on power generation: ȫ The Impact of Large Losses in the Global Power Industry. ȫ Common Causes of Large Losses in the Global Power Industry. We trust that you will find this document both illuminating and helpful as you consider the risks your own organization faces. -
