Habitat modelling is a tool for regionalisation of biotic information by predicting the spatially explicit distribution of species on the basis of environmental properties. Since this recent method has a high relevance in questions of nature conservation and ecological research, there is a need to teach it in environmental studies. The multimedia GIMOLUS-environment provides all elements necess...

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...

Questions: How can the productivity of a generalist brood parasite be estimated? Does an invasive brood parasite have greater productivity (defined as fledglings/egg and fledglings/area) in a recently invaded habitat than in a habitat similar to its original range? Features of model: We developed a simulation model that uses Bayesian and Monte Carlo methods to integrate brood parasite productiv...

a study was conducted to determine habitat suitability of goitred gazelle (gazella subgutturosa) in kalmand-bahadoran protected area during four seasons of year 2003-2004.the geographic position of dispersal points of gazelle herds was recorded with global position system. the data were transmitted into attributed tables in arc view software and their layers were created. the maps of slope, alt...

Animal venoms have been used for therapeutic purposes since the dawn of recorded history. Only a small fraction, however, have been tested for pharmaceutical utility. Modern computational methods enable the systematic exploration of novel therapeutic uses for venom compounds. Unfortunately, there is currently no comprehensive resource describing the clinical effects of venoms to support this co...

fungal biomass of a. niger, the byproduct of citric acid fermentation, proved to be a worth biomaterial which can be so beneficial and practical. in environmental case, it can be a useful biosorbent for decolorization and detoxitation of wastewater samples. it can also be used as a cheap and suitable source for commercial production of some expensive and useful biopolymers such as chitin, chito...
