Realization of students' adaptation possibilities at group forms
The degree of influence of purposeful realization of group forms is considered on the correction of adaptation possibilities on employments by a physical culture. In an experiment 326 students of the first course took part with violation of locomotorium. Physical exercises were examined as a health mean. Therefore regular employments were sent to maintenance of high capacity and strengthening of functional possibilities of organism. The indexes of psychomotor and sensory organization of personality must be purposefully formed on group employments on a physical culture already from the first semeste
MO CVD obtaining composite coatings from metal of platinum group on titanium electrodes
In the present paper we report obtaining composite coatings based on platinum metals by means of CVD technique. Platinum-, iridium- and ruthenium-containing coatings were deposited onto titanium substrates. Platinum bis-(2,4-pentanedionate), iridium tris-(2,4-pentanedionate), and ruthenium tris-(2,4-pentanedionate) were used as precursors. Corrosion resistance of the obtained samples is investigated with respect to the deposition conditions (substrate temperature and flow rate of the gas reagent – oxygen). Investigation was carried out using the electrolysis in sea water simulated solutions under active evolution of oxygen. It is stated that platinum coatings exhibit longer mean lifetime, in comparison with iridium and ruthenium samples. Service lifetime of the best electrodes exceeded 600 hours
