background: cervical spondylotic myelopathy (csm) is a common cause of significant clinical morbidity. the japanese orthopedic association cervical myelopathy evaluation questionnaire (joacmeq) is a measure of health-related quality of life in these patients. objectives: this study aimed to cross-culturally translate and validate the joacmeq in iran. patients and methods: this study was a prosp...

the present study pursued two goals: first, to discover the subscales underlying the teacher status scale (tss); and second, to reveal the status of the teachers of persian, arabic, and english in iranian junior high school students’ perceptions in order to determine the relative roles of national, religious, and western influences in the identity construction of the students. the data was coll...

the objective of the study was to develop a simple, specific and stability-indicating hplc method for the simultaneous determination of creatine phosphate sodium (cps) and its related substances in pharmaceutical formulation. separation of creatine phosphate sodium from its major process impurities and degradation products was achieved on a hypersil bds c18 column (250 × 4.6 mm, 5 μm) with an a...

runoff and sediment measurement is difficult in mountain watershed because of many different problems such as time and financial limitations. so using simulation model is necessary in this regard. accuracy and precision evaluation of models for different watershed of iran is necessary. the aim of this study was the evaluation of swat model efficiency in simulation of runoff and sediment yield i...

in this study, application ofweap model (soil moisture method) have been investigated for simulating hydrological behavior in ahar-chai basin. according to the development of pressurized irrigation systems in this basin, since 2005, two models were carried out for two periods, pre-pressurized period (1998-2006) and pressurized period (2006-2013). irrigation method in first model was surface irr...

since the change of land use accrued in the iran, especially in northern iran, this research aims tocompare the spatial variability of soil properties in three adjacent land uses including cultivated by wheat lands, grazing lands and forest lands covered by juniperus sp,  fagus orientalis, quercus castanifolia, and acer velotinum species in kiasar region, mazandaran province, northern iran. som...

the purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the ctpa on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, q...

conjugation of methotrexate (mtx) (mw 454) with different molecular weights of polyethylene glycol (peg) including methoxy-peg (mpeg) 750 d and 5000 d and diol-peg 35000 d led to compounds that are physicochemically highly different from the parent compound, mtx. in this study, an hplc system consisting of c8 column and uv detector (?=342 nm), using a mixture of 30:70 v/v phosphate-citrate buff...

heretofore, a vast spectrum of pattern recognition methods has been considered by researchers to design credit scoring models. but what has not been considered enough in these studies is the lack of consideration of the needs of this subject which differentiate it from a simple classification. it is necessary to observe the costs of a wrong classification, because practically the cost of improp...
