Background According to the general health policies issued in 2014, Health Impact Assessment (HIA) or Health Annex should be implemented in Iran. The present study provided a model for executing HIA in the Iranian context as a developing country. Methods This is a system design study with the qualitative approach. The data on the system components were gathered via reviews of the literature, ...
National and international pressure is growing for public policies and programmes to be prospectively evaluated to determine what their impacts will be on public health. This is evident from statements from bodies including the WHO, 1 the European Union, 2 and the British Medical Association 3 and may be seen as a natural development of evidence-based principles that are currently being applied...
BACKGROUND Transport and its links to health and health inequalities suggest that it is important to assess both the direct and unintended indirect health and related impacts of transport initiatives and policies. Health Impact Assessment (HIA) provides a framework to assess the possible health impacts of interventions such as transport. Policymakers and practitioners need access to well conduc...
The nonlocal enhancement in the velocities of charge carriers to ionization is shown to outweigh the opposing effects of dead space, increasing the avalanche speed of short avalanche photodiodes (APDs) over the predictions of a conventional local model which ignores both of these effects. The trends in the measured gain–bandwidth product of two short InAlAs APDs reported in the literature suppo...
BACKGROUND Thomson Institute for Scientific Information's journal impact factor, the most common measure of journal status, is based on crude citation counts that do not account for the quality of the journals where the citations originate. This study examines how accounting for citation origin affects the impact factor ranking of dermatology journals. METHODS The 2003 impact factors of derma...
the aim of the paper presented here is to develop the ti - micralloyed steel in otrer to oprtmize the mechanical properties after direct quenching from hot forging temperature. for this purpose, seven melts containing various amounts of titanium were prepared and cast in metal and sand molds. from the ingots, cast in metal mould, tractor links were produced by hot forging. the produced links we...
purpose: to evaluate the effect of fullerene on chemical properties of naphazoline drug in water by density functional theory (dft) methods. materials and methods: naphazoline belongs to the imidazoline class of sympathomimetics. the present study on naphazoline drug and its fullerene connected form were carried out using computerized calculations of gaussian program in b3lyp/6-31g leve...
Abstract: mechanical properties of AISIH 13 hot-work tool steel have been studied. Cast samples made of the modified new steel were homogenized and austenitized at different conditions, followed by tempering at the specified temperature ranges. Hardness, red hardness, three point bending test and Charpy impact test were carried out to evaluate the mechanical properties together with characteriz...
BACKGROUND The aim of this study was to measure the oral health-related quality of life (OHRQoL) after maxillary sinus augmentation to determine the physical and psychological impact of this procedure for the patient. METHODS Three hundred sixteen patients treated with an external or internal maxillary sinus augmentation and a total of 863 implants in the Department of Oral and Maxillofacial ...
Earthworms are an important component of soil fauna because of their fundamental impact on soil physical, chemical and biological properties. To evaluate the effects of earthworms on some soil chemical properties as well as plant growth indicators, an experiment was carried out in a completely randomized design in greenhouse conditions. The first factor involved the presence or absence of earth...
