This book was released on 2012-12-06 with total page 938 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space missions subject human beings or any other target of a spacecraft to a radiation environment of an intensity and composition not available on earth. Whereas for missions in low earth orbit (LEO), such as those using the Space Shuttle or Space Station scenario, radiation exposure guidelines have been developed and have been adopted by spacefaring agencies, for exploratory class missions that will take the space travellers outside the protective confines of the geomagnetic field sufficient guidelines for radiation protection are still outstanding. For a piloted Mars mission, the whole concept of radiation protection needs to be reconsidered. Since there is an increasing interest of many nations and space agencies in establishing a lunar base and lor exploring Mars by manned missions, it is both, timely and important to develop appropriate risk estimates and radiation protection guidelines which will have an influence on the design and structure of space vehicles and habitation areas of the extraterrestrial settlements. This book is the result of a multidisciplinary effort to assess the state of art in our knowledge on the radiation situation during deep space missions and on the impact of this complex radiation environment on the space traveller. It comprises the lectures by the faculty members as well as short contributions by the students given at the NATO Advanced Study Institute "Biological Effects and Physics of Solar and Galactic Cosmic Radiation" held in Armacao de Pera, Portugal, 12-23 October, 1991.

Download or read book The Early Effects of Radiation on DNA written by E.M. Fielden and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the biological effects of ionising radiation closely followed the identification of such radiation. The realisation that DNA is the site of genetic infonnation in cells subsequently focussed attention on DNA as an important target in the lethal and mutagenic effects of ionising radiation. Thus radiation effects upon DNA became an important area for fundamental scientific studies by radiation biologists, chemists and physicists. To a first approximation, the concerns of the three disciplines can be divided by time scales: the physical process of energy deposition from photon or charged 16 12 particle and subsequent relaxation (-10- to 10- secs), followed by chemical 12 2 reactions (- 10- to 10 secs), and fmally, the expression of biological effect (minutes to years). Thus, the concept of 'early processes' conveys different ideas to different scientists, although they are all interrelated. To attempt to describe in any detail all these processes is a mammoth task which is not made easier by the different conventions and experimental approaches of the three disciplines. However, the recent advances in all these scientific areas seemed, to the organisers at least, to offer the opportunity to stimulate more active interaction between physicists, chemists and biologists. With this in mind, a multi-disciplinary workshop was organised, which brought together some fifty scientists to present their own specialist interests and, through extensive discussion, explore which problems are of high priority and require input from the different disciplines to resolve them.

Download or read book The Computer Boys Take Over written by Nathan L. Ensmenger and published by MIT Press. This book was released on 2012-08-24 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contentious history of the computer programmers who developed the software that made the computer revolution possible. This is a book about the computer revolution of the mid-twentieth century and the people who made it possible. Unlike most histories of computing, it is not a book about machines, inventors, or entrepreneurs. Instead, it tells the story of the vast but largely anonymous legions of computer specialists—programmers, systems analysts, and other software developers—who transformed the electronic computer from a scientific curiosity into the defining technology of the modern era. As the systems that they built became increasingly powerful and ubiquitous, these specialists became the focus of a series of critiques of the social and organizational impact of electronic computing. To many of their contemporaries, it seemed the “computer boys” were taking over, not just in the corporate setting, but also in government, politics, and society in general. In The Computer Boys Take Over, Nathan Ensmenger traces the rise to power of the computer expert in modern American society. His rich and nuanced portrayal of the men and women (a surprising number of the “computer boys” were, in fact, female) who built their careers around the novel technology of electronic computing explores issues of power, identity, and expertise that have only become more significant in our increasingly computerized society. In his recasting of the drama of the computer revolution through the eyes of its principle revolutionaries, Ensmenger reminds us that the computerization of modern society was not an inevitable process driven by impersonal technological or economic imperatives, but was rather a creative, contentious, and above all, fundamentally human development.
