Mutual influence of intermodal and fundamental four-wave mixing of 1.0 µm and 1.5 µm nanosecond pulses in a dual-wavelength fiber laser.

We introduce the experimental and theoretical investigation of the mutual influence of two four-wave mixing (FWM) processes during the propagation of high-power nanosecond pulses at 1030 nm and 1562 nm wavelengths in the few-mode optical fiber. Both fundamental mode FWM (FM FWM) of laser pulses at these wavelengths, and intermodal FWM (IM FWM) of 1030 nm pulses, have common anti-Stokes components at 1003 nm wavelength. This leads to the mutual influence of FWM effects.

Social-Psychological Satiety: Empirical Study of a New Phenomenon.

This article is devoted to the development of a new phenomenon in the field of social psychology of the city-satiety with living conditions in a metropolis. The study involved 87 people aged 18-30 years. The aim of the study was to identify and analyze the expression of the satiety of young Moscovites with living conditions in the metropolis, and its dependence on the sources of experience of this state.

[COMPARATIVE ANALYSIS OF TIGHT JUNCTIONS OF EPITHELIUM OF RATS JEJUNUM UNDER THE EFFECT OF LIPOPOLYSACCHARIDE AND CHOLERA TOXIN].

Aim: Comparative study of tight junctions and ultrastructure alterations of enterocytes of mucous membranes of jejunum of rats under the effect of lipopolysaccharides and cholera toxin.

Materials And Methods: Lipopolysaccharides (Sigma-Aldrich, Germany) and cholera toxin (Sigma-Aldrich, Germany) were used. The study was carried out in Wistar line rats.

[Calculi in artificial urethra].

The article presents a successful experience of the treatment of long-term complication of ure-throplasty performed by the modified Cecil-Culp procedure using flap of skin of the scrotum with preserved hair follicles. The removal of calculi in artificial urethra occurring decades after the surgery was required. The use of combined method oftreatment led to a good clinical outcome.

[Early progressive organ failure in patients with severe acute pancreatitis].

The aim of the study was to investigate the role of early multiple organ failure in 152 patients with severe acute pancreatitis admitted to the intensive care unit for the period from 2002 to 2009. The group of patients with early progressive multiple organ failure had high early (29%) and overall mortality (45%) rate, infectious complications rate (39%) and long intensive care unit stay (median - 8 (5; 18) days). Based on the statistical analysis of data the criteria to predicted risk progression of multiple organ failure on admission were: APACHE II score ≥12, SOFA score ≥4, failure >2 organs/systems, Ranson score ≥7.
