background: numerous studies have assessed risk factors for multiple sclerosis (ms), but regarded to paradoxical results & specific ethnical- cultural circumstances in ahvaz, as a city in iran, this case-control study was aimed to assess some factors related to lifestyle (consumption & exposure with cigarette smoking, duration & surface of sun light exposure, exposure to pets and farm animals) ...
We introduce an algorithm to estimate the optimal exposure parameters from the analysis of a single, possibly underor over-exposed, image. This algorithm relies on a new quantitative measure of exposure quality, based on the average rendering error, that is, the difference between the original irradiance and its reconstructed value after processing and quantization. In order to estimate the exp...
Background & Objectives: Some case-report studies in Iran showed probable association between anthracosis and smoke exposure due to baking homemade bread, population. Therefore we estimated the population attributable fraction (PAF) for this probable association in Iranian population. Methods: A hospital-based case-control study, including 83 anthracotic subjects (cases) with 72 controls f...
In this issue of the European Respiratory Journal, DUMAS et al. [1] describe associations between occupational disinfectant exposure and asthma control in US nurses. Asthma control was defined by using the Asthma Control Test (ACT) and based on responses to five questions on activity limitations, frequency of symptoms and frequency of use of quick-relief medication in the past 4 weeks (β-agonis...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
