quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. this study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in gorgan city. cross-section survey data were gathered...

the occurrence of chatter vibrations in boring operation has a great influence in improving workpiece dimensional accuracy, surface quality and production efficiency. in this paper instability analysis of machining process is presented by dynamic model of boring machine. this model, which consists of machine tool’s structure, is provided by finite element method and ansys software. the model is...

We explore how the dilepton production rate is modified near critical temperature of color superconductivity and QCD point by soft modes inherently associated with phase transitions second-order. It shown that affect photon self-energy significantly through so called Aslamasov-Larkin, Maki-Thompson density states terms, which are known responsible for paraconductivity in metalic superconductivi...

intrbackground and objectives: good medical nutrition therapy (mnt) is crucial to inpatients' health and treatment, and is part of routine hospital cares. surgery ward is a highly danger-prone section in any hospital. the present study was conducted for a proactive risk analysis of nutrition and food distribution in mashhad qaem hospital’ women’s surgery ward in 2013 through health care fa...

Many social researchers measure multidimensional variables, such as rural leadership, by aggregating the scores of individual dimensions / sub-dimensions. These dimensions / sub-dimensions are highly correlated and have inherent problem of multicolinearity which causes attenuation in measurement. In order to overcome this problem, the M-K-J-B-D method developed by a group of researchers, has be...
