  Results of researches of gas sensitive properties of zinc oxide films grown by reactive rf magnetron sputtering was shown. Process parameters, affected on the gas-sensitive ratio, response time, recovery time and the type of electrical conductivity of obtained films were identified. Optimal modes of magnetron sputtering of zinc oxide for implementing gas sensors (RF sputtering Zn target in a gas mixture of oxygen and argon at a concentration of 80% oxygen, a chamber pressure of 0.8 Pa and the magnetron power 100 W) were established. Avarage response time on NO2 gas was 5-15 sec.  The obtained values ​​of the gas-sensitivity were in the range 30-67% for NO2 concentrations from 20 to 100 ppm, CO and CO2 from 50 to 100 ppm and 81-97% for higher gas concentrations from 500 to 1000 ppm.

Article focuses on the use of statistical models to predict tolerability surgery using intracavitary hyperthermic chemotherapy (IHCT) and the definition of indications and contraindications to perform operations and tolerability for patients with cancer based on the hemostatic patient. This technique allows a high enough accuracy to prediction portability planned surgery, duration of disease-free period, the period and quality of life in the immediate and late postoperative period.Improve treatment of patients with malignant tumors of the abdomen and pelvis, is one of the priorities of modern health care. Relevance of various parameters of immunity, clinical and biological parameters of homeostasis and prognosis of malignant disease in humans will significantly reduce the proportion of late diagnoses of relapses. Recently there has been increased research to find a method of complex cytoreductive surgery and the use of cytotoxic drugs, and physical therapies, one of which is a local intraoperative hyperthermic chemotherapy. With the help of statistical methods has been studied the degree of influence on the parameters IHCT immunity and an estimate of the nature of the immunological changes in different types of surgery. Methods of binary logistic regression analysis was calculated diskriminatnogo forecast portability operation - patient survival probability. Based on the method of multiple regression were obtained algorithms calculate the duration of life of patients after surgery, and the duration of DFS. Studies based on the factor analysis showed that the main factors affecting the prognosis of disease-free period and the period of life are the morphological structure of the tumor volume cytoreduction, the sum of your immune system and cancer markers. Peritoneal cancer index, sex and age of the patient does not have a significant effect on these parameters. Thus, the introduction into clinical practice of the proposed computer systems and statistical forecasting models allow physicians to objectively evaluate the performance of homeostasis, the portability of the planned surgery, more accurately predict the course of the cancer disease and the likelihood of recurrence of the disease and the duration and quality of life.

  The purpose of investigation is to examine the effect of adaptation to difficult-house physical stress on the regulation of the vertical posture of man. For the analysis of the ability to maintain a vertical position used stabilographic hardware-software complex "Stabilan-1-02" (JSK Rhythm ", Russia). The ability to maintain a vertical position was evaluated in two static positions: 1) the main stand (OS) in the presence and absence of visual information, and 2) dip (PP) in the presence of visual information. Revealed that an increase of physical performance ability to maintain balance in static positions, especially in the complicated conditions (deprivation of visual information and static muscle tension) increases.
