The issues of waste generation in batch process plants differ in many aspects to continuous plants. Despite the smaller-scale of processing, complexities from unsteady state profiles, discontinuities, and run-to-run variations make waste minimization in batch plant more challenging. In this paper, we present a systematic methodology for waste minimization analysis of a batch process. The method...

THE existing experimental studies of small task-oriented groups have generally employed noise-free communication, in the sense of information theory (i, 2, 5). One exception is the work of Heise and Miller (4) in which measured amounts of acoustic noise were introduced into the telephone network connecting the members of a small group. The experiments reported here investigate the effects of se...

This paper re-introduces the concept of in situwashing of wire mesh demister screens that are used in the separation of entrained juices from vapour streams. The use and the positioning of proprietary spray nozzles are explained and the visual observations are noted. screens tend to be roughly handled and suffer, in some cases, quite severe mechanical damage. With today's prices of screens bein...

Automated medical concept recognition is important for medical informatics such as medical document retrieval and text mining research. In this paper, we present a software tool called keyphrase identification program (KIP) for identifying topical concepts from medical documents. KIP combines two functions: noun phrase extraction and keyphrase identification. The former automatically extracts n...

The globalization of the economy is leading to greater diversification among user groups. Product designers will therefore have to take account of the cultural differences between these user groups. This article first defines the construct of culture with regard to human–computer interaction and presents various possible cultural influences. It then considers how the concept of culture is defin...

Introduction / objectives Healthcare-associated infections affect hundreds of thousands of patients worldwide every year. Hand washing is a basic measure to reduce infections. The aim of this study was to evaluate the adherence to hand washing opportunities among the multidisciplinary team and to search for possible causes or situations that might promote hospital infections, including cross in...

GREICE OLIVEIRA: Influence of tooth age and application time on the microtensile bond strengths of different adhesive systems to dentin. (Under the direction of André V. Ritter) This study evaluated the effect of tooth age and application time on the microtensile bond strengths (µTBS) of different adhesives to dentin. One-hundred twenty intact human teeth were mechanically ground to expose mid-...
