Analysis of U.S. Senate Web Sites For Disability Accessibility

U.S. federal government web sites have increased significantly the level of services and information offered to various internal and external stakeholders. The Workforce Investment Act of 1998 amended Section 508 of the Rehabilitation Act of 1973, which complemented the intent and aims of the 1990 Americans with Disabilities Act (ADA). As a result, federal agencies and departments were mandated to provide disabled stakeholders with access to key information from federal web sites. However, since this enactment, some federal web sites still do not meet fully the legal requirements to accommodate users with disabilities. Additionally, web sites of members of the U.S. Congress technically do not fall under regulation. Without regulation, non-adherence to accessibility standards by congressional web sites may result in poor or ineffective utilization by citizen consumers or other stakeholders with disabilities. The purpose of this study is to examine the accessibility statistics for a pseudo-random sample of 50 web sites of U.S. Senators. The main web page of each site was evaluated with an online web site analysis software tool – Truwex. Three factors were used to gauge the level of accessibility: criteria based on Section 508, WCAG 1.0 standards, and WCAG 2.0 standards. Results suggest that the vast majority of the U.S. Senate web sites do not meet the federal legal guidelines that otherwise are imposed on other U.S. governmental agencies and departments. Many of the sites contain consistent patterns of non-compliance, and some minor changes could result in increased accessibility for disabled stakeholders

Ingot beryllium-microstructural and mechanical property changes during can- rolling

Microstructural and mechanical property observations of ingotsource beryllium at selected points in the can-rolling process are reported. Recrystallization occur s concurrently with rolling at temperatures above 1800 deg F, and only partial recrystallization is observed during reheats at 1400 deg F. Most grain refinement induced by the rolling schedule occurs in the first 15 rolling passes. These represent 88 percent reduction from the ingot. A relatively small contribution comes from the final six passes which bring the total reduction from the ingot to 95 percent. Information was also obtained on the effects of the rolling schedule on the properties of the stainless steel can. (auth

Can-rolling of beryllium ingots

Aspects of hot-rolling cast-beryllium billets canned in 304 stainless steel are examined. Emphasis is placed on the development of the proper rolling schedule to completely convert the columnar cast structure to a uniform equiaxed one. Also emphasized are curling difficulties found in rolling this two-metal composite. The curling is found to depend chiefly on friction between ths billet and work rolls. Lubrication and roll surface finish are found to be the key variables which in turn control friction. Curling is best prevented by having a higher friction coefficient on the bottom billet surface than on the top during rolling. (auth
