The energy spectra of the secondary ion emission (SIE) for transition metals of the fourth period are calculated under the assumption that SIE is caused by the joint action of electron-exchange and kinetic ion emission (KIE) mechanisms. Some improvement of the KIE theory is carried out for the cases of high (of the order of tens of keV) and low (less than 2 keV) energies EO of bombarding ions. It is found that the KIE plays an essential role in SIE, starting from the EO value of the order of tens of keV. It is shown that the KIE energy spectra (1) are broader than the sputtering energy spectra by an order of magnitude, (2) differ essentially in both cases indicated, (3) show a peak (at high EO in accordance with an experiment) or a break (at low EO) near to the secondary ion energy corresponding to the KIE threshold. 相似文献

The combined anterolateral osteoplastic fixation of the spine was carried out on 17 cases out of 73 operated upon for pathological spinal changes of various etiology. The tibial crest rigid homograft and the rib autograft on vasoneuromuscular feeding pedicle were used. Such a combination of bone grafts possessing different mechanic and osteogenic properties permitted to obtain a reliable fixation of the spine for all the period necessary for anatomic and functional reconstruction of the grafts. 相似文献

Flexner's dysentery is often accompanied with intestinal dysbacteriosis. Disbiotic changes in the intestine contribute to specific shigella endotoxins entering blood flow thus prolonging clinical symptoms of the underlying disease. Administration of bacterial biological preparations (bifidumbacterin forte, lactobacterin) relieves specific endotoxemia, reduces the duration of the disease and has an immunomodulating action. 相似文献

Reaching the goals moving with different speed (from 1 to 400 mm/sec), the chimpanzee revealed respective behavioural, emotional, instrumental, and cardiovascular responses. When obscuring the goal for a certain time, the chimpanzee nevertheless managed to reach it, the relations between the speed of approaching goal and behavioural or instrumental responses being preserved. Thereupon, the chimpanzee are able to reach the goal provided the latter's trace exceeds 5-10-fold the time of really acting stimulus. 相似文献

The authors elaborated measures aimed to lower mortality and higher life expectancy among workers of able-bodied age. The recommendations involve changes in technology of drift mining, improved electric safety of technologic equipment, annual analysis of mortality parameters among miners, accomplishment of prophylactic recommendations on treatment of functional cardiovascular disorders, provision of workers with pectin as a therapeutic and prophylactic nutrient. 相似文献

In the article the final analysis of organization of surgical care during the local military conflict in northern Caucasus was presented. The real possibilities of different medical units such as single medical company and medical squadron of special assignment was described. Also concrete contents of emergency specialized surgical care and its role in improvement of outcomes in patients with combined combat injuries was reflected. Mortality in this patients was decreased from 25.2 to 12.8%. The defects of surgical care were analyzed and the main ways of improvement of surgical care in local military conflict were presented. In the result of using the principle of moving the medical care closer to the wounded in the whole system of consecutive care the mortality was decreased up to 1.3%. 相似文献
