This paper briefly considers the application of the principles of Empirical Modelling to an analog mechanical computer of WWII, and puts forward the theory that this primitive early computer, that followed such different principles to today's all-purpose computers, had properties of its design in common with EM models. The computer and system in question are related briefly to the principles of...

to evaluate integrated weed management on yield and weed biomass of bean an experiment were conducted as a split plot based on randomized complete block design with three replications at the research station of agriculture  in damavand in 2014.main plot of the mechanical control (cultivation)levels including the application and no application of cultivator and sub-plots chemical control levels ...

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 ...

rice is among the most important food crops throughout the world. hybrid rice benefits from about a 30 percent yield advantage over the conventional pure line varieties and this phenomenon can play an important role in fighting world hunger. to diminish the damage of rice pests, development of insect pest management strategies in hybrid rice is necessary. this study was aimed at evaluating the ...

introduction: cholestasis is impairment of normal bile excretion into the duodenum and classified as mechanical and non mechanical cholestasis. mechanical cholestasis presents with increase in bile duct diameter or obstruction in bile duct in an ercp. cholestasis leads to different complications. one of these complications is mucosal peptic erosion leading to gastrointestinal bleeding, perforat...
