considerable investments have been made in establishing wastewater treatment plants (wwtps). however, evaluation of the performance of plants during recent years, when more wwtps have become operational, shows that effluent quality criteria were not met in many instances. preliminary assessment of the operational problems of wwtps in iran disclosed that numerous factors affect this issue of eff...

Considerable investments have been made in establishing wastewater treatment plants (WWTPs). However, evaluation of the performance of plants during recent years, when more WWTPs have become operational, shows that effluent quality criteria were not met in many instances. Preliminary assessment of the operational problems of WWTPs in Iran disclosed that numerous factors affect this issue of eff...

in the past, medical device design always was performed with medical engineers, technicians and physicians in all design stages and the industrial design role was pale in this field. today the industrial design responsibilities in designing of these devices are considered increasingly. the industrial design role in medical device design was investigated in two fields. first are aesthetic and it...

OBJECTIVES To describe participation and health-related quality of life of Dutch children and adolescents with congenital lower limb deficiencies in comparison with typically developing children, and to explore differences between various degrees of limb loss and between parental reports and self-reports on health-related quality of life. DESIGN Cross-sectional study. METHODS Participation ...

From the available evidence, alsohol ingestion per se does not appear to be carcinogenic. While alcoholism constitutes a major and serious social problem, it is not clear to what extent it constitutes a major health problem. We suggest that excessive alcohol ingestion coupled with a nutritional deficiency or some other insult (e.g., smoking) may be carcinogenic. Alcohol and/or several nutrition...

If the role of software libraries is to communicate information about software artefacts between software engineers, it is vital that the information be stored in such a manner as to be readily understandable. The designs of existing software libraries present several cognitive impediments to a software engineer, hindering the understanding of library organisation and content. In this paper, a ...

The objective of this research was to study and identify ergonomic deficiencies in computer workstation design in typical offices. Physical measurements and a questionnaire were used to study 40 workstations. Major ergonomic deficiencies were found in physical design and layout of the workstations, employee postures, work practices, and training. The consequences in terms of user health and oth...

all practical digital circuits are usually a mixture of combinational and sequential logic. flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. the concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...
