Computer and storage systems contain many printed circuit boards that utilize common pieces of logic and technology. New technologies are signaling faster, with increased edge rate, clocking off both edges, leading to reduced system level timing and noise margins. The reuse of signal integrity and timing analysis environments with their associated models results in significant savings in manpow...

Organization of Entries This publication is a compilation of select journal articles and reports from years 1988 through 2010 that are related to the need for condoms in the prison system. The bibliography was developed by conducting an extensive literature search utilizing MEDLINE (The National Library of Medicine's premier bibliographic database) and web-based resources. The entries are group...

Textbooks often come as printed, linear, standalone, monolithic resources. However, teachers, more often than not, tend to draw from various sources to prepare their courses and modify or complement existing content. We describe a web platform for textbooks based on features of source-control management systems to enable teachers to tailor a specific textbook to their needs. Teachers can each c...

A networked learning environment to support health education in five institutions was developed using XML, SQL and object databases and Zope. Paragraphs from curriculum documentation, communication tools and learning resources are assembled dynamically from distributed databases (with distributed authorship) into a unified student portal. Information can be dynamically reconfigured for differen...

When library consortiums are formed, the existing environment about users’ preferences and difficulties need to be studied. Initiating such studies would enable to incorporate the findings as the major input in consortium formation. Introduction The web resources and the use of web as a tool is changing the way users live and learn. While in the early phase, the World Wide Web was mainly used f...

The unibody lab-on-a-chip (ULOC) concept entails a fast and affordable micro-prototyping system built around a single monolithic 3D printed element (unibody). A consumer-grade stereo lithography (SL) 3D printer can configure ULOCs with different forms of sample delivery, transport, handling and readout, while minimizing material costs and fabrication time. ULOC centralizes all complex fabricati...

This paper an presents analysis of metals in waste of printed circuit boards (PCB) covering types of PCB, segregated from PC computers, mobile phones, and mixed. The presented data identifies metals and other substances found in PCB waste based on elemental and technical analysis of PCBs. PCB categorization based on gold concentration is presented, resulting in two groups: electric and electron...

This article is focused on the determination of lidocaine hydrochloride as a local anaesthetic drug. A potentiometric method based on modified screen-printed and modified carbon paste ion-selective electrodes was described for the determination of lidocaine hydrochloride in different pharmaceutical preparations. It was based on potentiometric titration of lidocaine hydrochloride using modified ...
