a mathematical model was developed to predict the effects of wind speed, light, ph, temperature, dissolved carbon dioxide and chemical oxygen demand (cod) on dissolved oxygen (do) in fish ponds. the effects of organic feeds, aeration and fish activity were added to the model developed by kayombo et al. for waste stabilization ponds (ecological modeling 127(2000): 21-31) to reflect the situat...

mathematical models have the potential to provide a cost-effective, objective, and flexible approach to assessing management decisions, particularly when these decisions are strategic alternatives. in some instances, mathematical model is the only means available for evaluating and testing alternatives.  however, in order for this potential to be realized, models must be valid for the applicati...

conclusions we concluded that the fcchl scales are valid and reliable, and can be used to measure health literacy among iranian diabetic patients. however, further research is needed to establish stronger psychometric properties for the use of this questionnaire in iran. results exploratory factor analysis (efa) identified three main factors with 27.07%, 22.46%, and 16.23% of extracted variance...

objectives we aimed to translate the bapt into farsi, assess its content validity, and examine its reliability and validity to identify exclusive breastfeeding discontinuation in iran. materials and methods the bapt was translated into farsi and the content validity of the farsi version of the bapt was assessed. it was administered to 356 pregnant women in the third trimester of pregnancy, who ...

background good knowledge, attitude and practice (kap) of the physicians allow them to handle their patients in such a way that they prevent themselves from contracting, and their patients from spreading, the infection. however, the iranian standardized kap questionnaire of physicians about viral hepatitis is not available. so, we developed a standard questionnaire. objectives the purpose of th...

Cloze was officially introduced in a journal on Journalism as a technique for estimating text readability and as "a new psychological tool for measuring the effectiveness of communication" (Taylor, 1953: 415). Different varieties of cloze have since been developed and experimented upon as measures of such diverse traits as reading comprehension and language proficiency. The findings of numerous...
