The prognosis of the professional fitness of sailors for action under extreme conditions]

The researches described in this article made it possible to substantiate a number of important professional qualities of seamen which are indispensable in extreme situations. Three professional categories, namely command duty officers, operators and specialists of the local posts were the matter of these researches. A combination of symptom complexes of individual qualities which predetermines a successful duty performance in extreme situations was disclosed. A complex of valid methods was substantiated for quantitative estimation of individual psychological qualities. On the basis of these symptom complexes the authors worked out the estimation criteria for prognostication of professional ability of seamen to act in extreme situations.     

Measurement of absolute intensities of some prompt gamma-lines from the 91Zr, 143Nd, 177Hf and 116,118-120,122,124Sn(n,gamma) reactions and isomeric cross-sections of 123m,125mSn by in-beam gamma-spectroscopy method.

The previously unknown absolute intensities of 28 prompt gamma-rays from the thermal neutron capture in 91Zr, 143Nd, 177Hf and 116,118-120,122,124Sn were measured by an in-beam gamma-spectroscopy method at the WWR-M reactor (PNPI, Gatchina). Cross sections of the production of isomers 123m,125mSn were also measured.     

Clinico-anatomical basis for using the variants of proximal gastric vagotomy in the treatment of gastroduodenal ulcers

Anatomical examinations (33 cadavers) for studying parasympathetic innervation of the upper abdominal organs formed the basis for developing a new variant of proximal gastric vagotomy--anterior seromyotomy of the body and fundus of the stomach in combination with posterior truncal or posterior selective vagotomy. This variant excludes mobilization of the esophagus and makes it possible to preserve the ligament apparatus of the esophago-gastric junction as well as the parasympathetic innervation of the pancreas, small and large intestine, kidneys, and adrenals, which may be a measure for the prevention of some ++post-vagotomy complications.     

Experience in the organization of heart surgery services to patients with disorders of heart rhythm and conduction in large cities

The article generalizes 17-year experience in the organization of surgical service for patients with disturbed rhythm and conductivity of the heart in Leningrad and the northwest region of the USSR. The work of the city center of surgery of arrhythmias is analysed. Prospective calculations were made. Basically new approaches to determining the regular number of persons on the staff and the number and type or operative interventions are suggested.
