background: hospitals are the central entity of each health care system and health promoting hospitals (hph) was launched by who in 1988. however, there has not been any accurate and detailed model for establishing a hph in iran up to now. therefore, this study aimed to determine factors affecting the establishment of a health promoting hospital in iran using factor analysis method. methods: th...

trichomoniasis, a worldwide prevalent infection, is a perfect example of interplay between the infecting parasite and the host, on which the presentation of disease depends. to study the pathogenesis, animal model is required for establishment of infection. in this study, by using strains of trichomonas vaginalis isolated from vaginal swabs and/or urine samples and maintained in axenic form fro...

the separation of olefin/paraffin mixtures is an important process in petrochemical industries, which is traditionally performed by low temperature distillation with a high-energy consumption, or complex extractive distillationand adsorption techniques. membrane separation process is emerging as an alternative for traditional separation processes with respect to low energy and simple operation....

objective: to study the mechanisms involved in amyloid formation processes, we made a mammalian cell culture model of amylin aggregation and characterized its properties. materials and methods: amyloid fibrils were extracted from cho cells and binding affinity to thioflavin t and congo red was investigated. then the apple-green birefringence of extracted fibrils was detected under polarized li...

hepatitis b (hb) is an infectious disease occurring worldwide which can be transferred by some professions, including hairdressers. health education is an essential component of public health campaign about this disease. the purpose of this study was to test the utility of the health belief model (hbm) in understanding and predicating the intention of hairdressers in prevention of hb in their c...

in this paper, a five–dimensional mathematical model is proposed for the transmission dynamics of hiv/aids within a population of varying size. in writing the model, we have divided the population under consideration into five sub classes of susceptible, infective, pre-aids, aids related complex and that of aids patients. the model has two non- negative equilibria namely, a disease free and the...

This paper describes the rainfall data generation processes, which were used to simplify the recharge model developed by Khazai and Spink. The principles of techniques used for single and two sites generation are discussed. The application of the techniques for extending the rainfall records at the existing stations and increasing arbitrarily the numbers of rain gauges within the catchment are ...
