introduction: the efficiency of muscular function is directly related to energy consumption. maintaining the dynamic equilibrium and fatigue during walking and other daily activities are the main problems in spastic cerebral palsy patients. recognition of mechanism and muscular function in these patients is important from a clinical and rehabilitational perspective. the objective of this study ...

This paper does research on order quantity and profits of members in cooperative and non-cooperative supply chains. First, the supply and demand model of members of non-cooperative supply chains is established, and optimization research on order quantity and price variables in this model has been carried out. Then the cooperation model in returnable cooperative supply chain is built by introduc...

In 2009, Röglin and Teng showed that the smoothed number of Pareto optimal solutions of linear multi-criteria optimization problems is polynomially bounded in the number n of variables and the maximum density φ of the semi-random input model for any fixed number of objective functions. Their bound is, however, not very practical because the exponents grow exponentially in the number d+1 of obje...

the aim of the present study was to evaluate the efficiency of the computer and internet training course from the viewpoint of dental students of kermanshah university of medical sciences in 2014. in this descriptive survey, the study sample included 39 dental students who entered university in 2011 and 2012. the required data were collected through a reliable and valid questionnaire using cens...

A deterministic model based on the gene flow method, considering the features of Iranian Holstein cattle population, was implemented in this study to evaluate the effect of altering the number of age-classes in the dams of future sire (DS) path and the number of dams required for breeding a young bull (YB), to be evaluated as future sire, on genetic gain and resultant economic efficiency of a g...

Two trials were conducted to study the effect of multi-steps phase-feeding (PF) program on growth performance of broiler chickens from 1 to 24 and 1 to 39 d of age. The control group was the nutrient recommendation of Aviagen (2019) with a three-step PF program (1-10, 11-24 and 25-39 d of age). In the first trial, the control group was compared with an eight-step PF program (PF8), and in the se...

abstract objective children suffering from cerebral palsy (cp), exhibit movement limitations and physiological abnormalities as compared to normal individuals. the objective of this study was to assess mechanical efficiency and certain cardiovascular indices before and after an exercise-rehabilitation program in children with dipelegia spastic cerebral palsy (experimental group) in comparison w...
