METHODS Ornidazole(20mg/kg body weight) were fed to rats. At the given time points,the serum and pancreatic tissue samples were collected. The concentrations of ornidazole in the serum and pancreatic tissue were measured by HPLC.
The five factors of pump unit maintainability are determined: maintenance objects,given conditions,given processes and means,given time,and given function.
The problem of spacecraft reorientation from its initial angular position into a desired final position within a given time interval with a minimum value of the angular moment is considered and solved analytically in this work.
The variation of the frequency at which the spectral intensity is maximal within a given time interval with the amplitude of an applied femtosecond pulse is simulated.
A system of nonlinear differential difference equations is derived, which describe the behavior of an oscillator with delay and inertia under the action of complex oscillations in a given time interval.
An algorithm for construction of the reachability domain by the given time instant ? for a nonlinear third order system under the condition of preliminary approach to a predefined point is proposed.
