hypothermia generates potentially severe complications in operating or recovery room. forced air warmer is effective to maintain body temperature. extremely low frequency electromagnetic field (elf-emf) is harmful to human body and mainly produced by electronic equipment including convective air warming system. we investigated elf-emf from convective air warming device on various temperature se...

in order to investigate effective factors on bread waste and determine effect genial of each factor on probability of being each family in three categories of low-medium, high and extra high bread waste, the order logit model and the 352 families data from mashad city were taken in use. the samples have been selected using a simple random sampling method. the survey of marginal effect in order ...

abstract: this work presents a numerical study to investigate the heat transfer characteristics of a 2-d rectangular composite porous radiant burner (cprb). in the construction of porous burner, the porous layer is considered to be composite consisting of upstream and downstream layers with equal thickness but with different physical and radiative properties. in the present work, a two dimensio...

in this paper, we describe our implementation of an interior point algorithm for large scale systems. first we identify system with small and medium methods convex optimization, then we use interior point method for identification. finally we offer an interior point method that uses nonlinear cost function and see that we achieve a good trade-off between error and cpu time. actually, in this pa...

There are different models for mapping and evaluation of desertification condition, such as global FAO_UNEP model. There are also several models for evaluation of desertification in Iran. In this study, tow fol/owing methods was used: 1-ICD method, (Iranian Classification of Desertification). 2- MICD method, (Modified Iranian Classification of Desertification). In this research, at first, these...

conclusions the current study revealed that a significant difference existed in hgs among the low, medium, and high bmi groups. a positive correlation existed between hgs and weight and height, while sex was the most significant factor affecting hgs. these findings can serve as a reference to assess hgs prediction, whereby the sex effect should be considered. results the results showed that the...
