Mycobacterium avium complex (MAC) and rapidly growing mycobacteria (RGM) such as M. abscessus, M. mucogenicum, M. chelonae, and M. fortuitum, implicated in health care-associated infections, are often isolated from potable water supplies as part of the microbial flora. To understand factors that influence growth in their environmental source, clinical RGM and slowly growing MAC isolates were gr...

In order to improve the overall efficiency of building energy usage, a grey water energy-recovery system, which adopted a multiple-function heat pump system, was proposed for domestic water heating, and space heating and cooling of buildings. A numerical model has been developed for investigation of annual energy and water consumptions of the proposed system and the conventional building energy...

The ability of public institutions to provide efficient and equitable potable water services is key to reducing water-borne diseases, one of the leading causes of morbidity and mortality in the developing world. In this article, a case study of potable water and public health programs in Tijuana, Mexico, is used to direct attention to practical examples of policy and institutional incapacities....

Growing demands for potable water have strained water resources and increased interest in wastewater reclamation for potable reuse. This interest has brought increased attention to endocrine-disrupting chemicals (EDCs) as emerging water contaminants. The effect of EDCs, and in particular natural steroid hormones, on humans is of heightened interest in the study of wastewater reuse in advanced l...

The objective of this work was to investigate the interactions between the level of concentrations of Ca, V Cr, Mn, Fe, Ni, Cu, Zn, As and Pb in potable water, soil, vegetation and school children hair and disease incidences of neoplasms, diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism, endocrine, nutritional and metabolic diseases, mental and...

This historical review traces the con­ cept of work throughout the develop­ ment of occupational therapy. Para­ digm shifting is used as a framework for describing the conceptual defini­ tions and therapeutic uses of work in four developmental stages. T he concept of work is funda­ mental to our profession; the terms occupation and therapy con­ note the strong relationship be­ tween healing and...

T he field of neurotrophin biology has made great advances in recent years to include a greater understanding of signaling pathways and broader understanding of the diverse biological roles of these molecules. This review will focus primarily on the nerve growth factor family of neurotrophins and how recent descriptions of the molecular function of both the ligands and the receptors have helped...

number of new drugs which have appeared during the last three years have been included and the author has been very wise in exercising a judicious caution in their selection. The sulphanilamide group of drugs which, is still in an experimental stage has received adequate attention. The book has been well written and brings out with great clarity the really important actions and therapeutic uses...
