Surface state of sacrificial copper electrode by electropolishing in hydrophobic ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide.

Anodic dissolution of natural surface-oxidized, air-annealed, cathodically reduced, and cathodically deposited copper in hydrophobic ionic liquid 1-buthyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide under galvanostatic conditions by means of gravimetric measurements was studied. The resulting samples were mirror-like oxide-free copper pattern. The mechanism of the electropolishing of oxidized copper surface was considered.

[Urgency of comparative spectral analysis of noises in sanitary inspection].

Spectrum (presentation, an image) is a set of all values of any that characterizes, for example, sound-wave propagation. In exact sciences, the expansion of oscillatory function in terms of harmonics, by calculating the Fourier coefficients denotes a spectral analysis. The paper discusses how to further improve the existing sanitary document regulating the order of noise measurement in the area of an apartment block and in residential and public buildings.

[Infusion-transfusion therapy of acute blood loss during early surgeries in children with severe thermal trauma].

Research results of the central hemodynamics, microcirculation and of oxygen status are described for 48 children (aged 8 months to 14 years) as observed during surgeries aggravated by massive hemorrhage in the routine infusion-transfusion therapy plus a 6% solution of INFUKOL GEK. Solution dosages of 6% were approved; the drug's positive effect on the central-hemodynamics condition, microcirculation and on the oxygen regime, as observed in the process of the infusion therapy made to compensate for a massive blood loss, was demonstrated; besides, the related shrinking of the infusion therapy total volume and the possibility to give up totally or to significantly reduce the blood-drug preparations, administered intraoperatively, were shown.

[On methods for unambiguous assessment of occupational environmental factors in occupational medicine].

Suggested system to formalize hygienic information is designed for definite and unambiguous assessment of varied totality of occupational environmental parameters in specific object of sanitary supervision; for study and analysis of physiologic, hygienic and clinical dependencies of workers' health state on the work conditions; for further specification of scientifically based prophylactic measures and social economic protection of workers.
