Results of 120 pancreatoduodenal resections are analyzed. Early postoperative period complications were seen in 51 (42.5%) patients. Overall lethality during 30 days after surgery was 13.3%. Over the last decade lethality reduced to 5%. Life time was

An investigation was made of steady-state propagation of laser beams which had an intensity dip on the axis (annular beams) on entering (z = 0) a defocusing medium. The transverse structure of the beam was calculated and studied experimentally for va

A two-layer model of an inhomogeneous medium is used in a study of the influence of a change in the transverse component of the velocity of wind on the nonlinear thermal effects (defocusing and refraction). Numerical calculations and experimental res

On the basis of linearized equations for perturbations in a one-dimensional light beam propagating in a moving medium with thermal nonlinearity, the article shows the possibility of an exponential growth of these perturbations with an intensity above

Numerical modeling methods are used to analyze thermal self-interaction of scanning optical beams in a moving medium. It is shown that the existence of a stagnant zone in the path increases considerably the nonlinear effects compared with the self-in

A theoretical analysis is made of the simultaneous influence of refractive index inhomogeneities and thermal nonlinearity of a medium on the broadening of a light beam. It is shown that the presence of a defocusing dielectric waveguide increases the
