Abstract Background The present study was designed to test the hypothesis that chronic very mild prenatal carbon monoxide (CO) exposure (25 parts per million) subverts the normal development of the rat cerebellar cortex.Studies at this chronic low CO exposure over the earliest periods of mammalian development have not been performed to date.Pregnan
We study the necessary and sufficient conditions on Ping Pong Tables the masses for the periodic solution of planar 4-body problems, where three particles locate at the vertices of an equilateral triangle and rotate with constant angular velocity about a resting particle.We prove that the above periodic motion is a solution of Newtonian 4-body prob
In crank presses, an important role is played by the presence of actuators with dwell, in which, with continuous movement of the input links, the output working link remains stationary at some part of the work.The use of a high-class structural group (fourth class) expands the functionality of the crank press, including it can ensure the link dwell
The great attention of scientific researches about vancomycin- resistant Enterococcus faecalis due to the great healthy problems in the world.Evaluation of E.faecalis virulence factors showed that all isolates (100%) were hemolysin, protease and aggregation substance producer, 30% were a gelatinase producer, and 40.7% were a lipase producer.The res
