A steel-concrete beam was taken as the study object. The algorithm of selecting number stiff supports for loaded with a concentrated lateral force in middle span has been refined. Stiff served to join steel strip concrete ensure their joint performance. refined based on condition equality longitudinal from action calculated load and maximum obtained after setting supports. In this case, forces ...

The relation between the activity of cells in the motor cortex and static force has been studied extensively. Most studies have concentrated on the relation to the magnitude of force; this relation is more or less monotonic. The slope of the relation, however, shows considerable variation among different studies and seems to be inversely associated with the range of forces over which the cell a...

OBJECTIVE The aims of this study were to compare different surgical approaches to rapid canine retraction by designing and selecting the most effective method of reducing resistance by a three-dimensional finite element analysis. MATERIAL AND METHODS Three-dimensional finite element models of different approaches to rapid canine retraction by reducing resistance and distraction were establish...

  Blackleg in cattle has been recognized since 1938 in Iran that mostly affects cattle in enzootic farm. Main object of this study was to prepare and formulate a concentrated potent vaccine for immunization of cattle against blackleg in Iran. Experimental concentrated blackleg vaccine was prepared according to the method described by FAO. The medium (Modified medium for production of experiment...

This paper develops a model of the geographic distribution of crime in an urban area. Agents select their occupation, residence, consumption, and housing. The paper is the first to formally study how the location of crime, the residence of workers, and housing prices are affected by the spatial allocation of police protection. It examines two opposite strategies of police deployment: concentrat...
