Dependence of defect introduction on temperature and resistivity and some long-term annealing effects

The effort reported here represents data of lithium properties in bulk-silicon samples before and after irradiation for analytical information required to characterize the interactions of lithium with radiation-induced defects in silicon. A model of the damage and recovery mechanisms in irradiated-lithium-containing solar cells is developed based on making measurements of the Hall coefficient and resistivity of samples irradiated by 1-MeV electrons. Experiments on bulk samples included Hall coefficient and resistivity measurements taken as a function of: (1) bombardment temperature, (2) resistivity, (3) fluence, (4) oxygen concentration, and (5) annealing time at temperatures from 300 to 373 K

Shortcomings in ground testing, environment simulations, and performance predictions for space applications

This paper addresses the issues involved in radiation testing of devices and subsystems to obtain the data that are required to predict the performance and survivability of satellite systems for extended missions in space. The problems associated with space environmental simulations, or the lack thereof, in experiments intended to produce information to describe the degradation and behavior of parts and systems are discussed. Several types of radiation effects in semiconductor components are presented, as for example: ionization dose effects, heavy ion and proton induced Single Event Upsets (SEUs), and Single Event Transient Upsets (SETUs). Examples and illustrations of data relating to these ground testing issues are provided. The primary objective of this presentation is to alert the reader to the shortcomings, pitfalls, variabilities, and uncertainties in acquiring information to logically design electronic subsystems for use in satellites or space stations with long mission lifetimes, and to point out the weaknesses and deficiencies in the methods and procedures by which that information is obtained

Le vêtement professionnel et l'inspection du travail, entre normes et pratiques

At the end of the 19th century and the beginning of the 20th, when the rules and the professional norms had to be established, the question of the clothing is a more carefully discussed question. We can find an inventory of these rules in the annals of the French Health and Safety Inspection. Indeed, the Health and Safety inspectors wrote a lot of reports in which they related, implicitely, both the existing speeches about the professional clothing and the habits of clothing that prevailed on the working places. The aim of this article is to show what were the roles of the inspectors, taken between the industrials and the Government, in the definition and the application of the laws. The experiments taken in the foreign countries make up a fundamental inspiring influence for the application of the clothing rules by the managers and the French government. The concern is then to outline the norms – in matter of security, of well-being and of gender – which were applied to the professional clothing, through the observable deformations between the law close to norms and the reality, at a time when the state intervenes more directly in the world of working to supervise it

En Toques! L'apparence des cuisinier.e.s, entre pratiques et représentations en France (XIXe-XXe siècles)

In the 19th century, professional constraints in French kitchens were many and various. Norms and practice required chefs to wear a professional uniform codified through a long process of historical construction. This outfit seems fixed in its form and colour, making it possible to identify the cook’s professional status by his clothing. Symbol of resistance of a male-considered activity, the French chef’s clothing underwent changes in order to meet the profession’s economic evolution and feminization during the 19th and 20th centuries in France

Annual Compendium of Disability Statistics: 2015

Statistics are a powerful tool—in research, policymaking, program evaluation, and advocacy. They are used to frame the issues, monitor current circumstances and progress, judge the effectiveness of policies and programs, make projections about the future, and predict the costs of potential policy changes. In the United States, statistics about the population with disabilities and about the government programs that serve people with disabilities—disability statistics—are often difficult to find. Numerous government agencies generate and publish disability statistics, and as a result, disability statistics are scattered and buried in documents and websites all across the federal government. The Annual Disability Statistics Compendium is a publication of statistics about people with disabilities and about the government programs which serve them. It is modeled after the Statistical Abstracts of the United States, published yearly by the U.S. Department of Commerce. The Compendium is designed to serve as a summary of government statistics
