Background: Multidrug resistant Enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. The main objective of the present study was to investigate the prevalence of antibiotic resistant Enterobacteriaceae in the domestic food related environments. Methods: Resistance to ampicillin, chloramphenicol, ...
background: although borage ( borago officinalis l.) is a valuable medicinal plant, no information is available on the responses of this plant to salinity. for this reason, it is necessary to determine responses of this plant to salinity . objective: since germination and early growth stage is one of the most critical phases of plant life under salinity condition this experiment was conducted ...
In the real world, many of the optimization issues are dynamic, uncertain, and complex in which the objective function or constraints can be changed over time. Consequently, the optimum of these issues is changed nonlinearly. Therefore, the optimization algorithms not only should search the global optimum value in the space but also should follow the path of optimal change in dynamic environmen...
background: water, sanitation and hygiene have a very important role in public health. poor sanitation is the cause of water contamination, which causes many types of diseases. the aim of this paper was to present the attributable death and disability adjusted life year (dalys) of untreated water and insanitary environments from 1990 to 2010 in iran. methods: in the global burden of disease 2...

Methodology of this research was baesd on synthesis of supervised and unsupervised classifications in GIS and ENVI softwares. Based on studies and calculat...
Virtual Geographic Environment Cognition is the attempt to understand the human cognition of surface features, geographic processes, and human behaviour, as well as their relationships in the real world. From the perspective of human cognition behaviour analysis and simulation, previous work in Virtual Geographic Environments (VGEs) has focused mostly on representing and simulating the real wor...
Background: Laboratories, workshops, and operational and field environments, as the most important practical training units in most academic disciplines, have a very important role in learning the necessary experience and skills of students. This study aims to investigate the principles and ethical challenges in these environments and is the result of experience, work and research of authors ov...
Background: Interaction is considered a necessary, and integral part in all forms of distance learning and web -based learning environments. That how much technologies can support and help interactions is one of the most important issues that should be considered in the web-based environment. These interactions seek to engage students with other students, teachers and also non-human contex...
nowadays, previously performance-oriented architecture of healthcare centers has been switched to creating a healing environment; and one of the most important pillars to create such an environment is omitting sound pollutions. today's hospital have chaotic situation regarding noise pollution not only in our country, but also in all over the world. the present study aims to provide a compl...
