The objective of this report is to highlight the impact of long-term aging effects on parts, assemblies and equipments by investigating characteristics of aging as they impact specific material classes.

This Part of YY/T 0681 specifies the guide for designed accelerated aging solutions. This Part applies to the rapid determination of the sterile integrity of the sterile barrier system specified in GB/T 19633.1-2015 and the effects that physical properties of its packaging material components are affected by the elapsed time.

This is a report on the state of the art of research on the phenomenon of the aging of asphalt-aggregate mixtures. Compared to research on the aging of asphalt cement, there has been little research on the aging of asphalt mixtures. Binder studies are considered as well as mixture sutdies, the relationship between laboratory aging tests and field performance, and the relationship between chemical composition and field performance. Recommendations are made for aging procedures which show promise for laboratory investigation. Test methods to evaluate aging are also considered. It is noted that extended heating procedures show the most promise for short-term aging and pressure oxidation and/or extended heating the most promise for long-term aging.

The Second Edition of Security Strategies in Web Applications and Social Networking provides an in-depth look at how to secure mobile users as customer-facing information migrates from mainframe computers and application servers to Web-enabled applications. Written by an industry expert, this book provides a comprehensive explanation of the evolutionary changes that have occurred in computing, communications, and social networking and discusses how to secure systems against all the risks, threats, and vulnerabilities associated with Web-enabled applications accessible via the internet. Using examples and exercises, this book incorporates hands-on activities to prepare readers to successfully secure Web-enabled applications.
