introduction: since nurses are the largest group of health care providers playing an important role in responding to disasters, evaluating the state of nursing and nursing knowledge about common patterns of disasters is undeniable in importance and necessity. however, based on studies conducted by researchers, there are few models for nursing that show nurses’ disaster readiness. this study was...

in this paper the real time operation of an automatic teller machine (atm) is analyzed using atimed petri net (tpn) model. in the modeling, the probability of arrivals, the speed andattentiveness of customers (clients) are taken to account. different parameters are based onthe statistical data. the model is simulated for 24 hours. the diagrams of number ofsucceeded customers, failed references ...

background: a good animal model for coronary surgery experiments has been difficult to establish. an ideal model should have the closest morphological resemblance to human beings. the objective of this study is to establish sheep as a model for these experiments. methods: the anatomical aspects of left anterior descending coronary artery (lad) and right internal thoracic artery (rita) in the sh...

The purpose of this study was to examine the expected returns of Carhart model compared to the capital asset pricing model and the implicit capital cost model based on cash and capital returns of growth and value stocks. The statistical population consisted of the companies listed in Tehran Stock Exchange and the time domain is between 2007 and 2016. By choosing Cochran sampling, 126 companies ...

Infiltration process plays an important role in water cycle of the nature. Conducting field experiments is necessary to determine the coefficients of infiltration equations due to the dependence of these coefficients to the soil type, soil surface conditions and the amount of initial soil moisture content. This study has been carried out in a field located in Islamic Azad University, Marvdasht ...

one of the main objectives of quantitative researches is assessment of models developed by qualitative studies. models validation through their testing implies that the designed model is representative of the existed facts. hence, this study was conducted to assess the clinical nurses' productivity model presented for iranian nurses' productivity. the sample of the study consisted of 360 nurses...

we study the history and recent developments in nonelementarymodel theory focusing on the framework of abstractelementary classes. we discuss the role of syntax and semanticsand the motivation to generalize first order model theory to nonelementaryframeworks and illuminate the study with concrete examplesof classes of models. this second part continues to study the question of catecoricitytrans...

introduction: in-service training of nurses plays an indispensable role in improving the quality of inpatient care. need to enhance the effectiveness of in-service training of nurses is an inevitable requirement. this study attempted to design a new optimal model for in-service training of nurses. methods: this qualitative study was conducted in two stages during 2015-2016. in the first stage, ...

in this paper we propose a simple non-parametric model for multiple crite-ria supplier selection problem. the proposed model does not generate a zeroweight for a certain criterion and ranks the suppliers without solving the modeln times (one linear programming (lp) for each supplier) and therefore allowsthe manager to get faster results. the methodology is illustrated using anexample.
