Hybrid materials based on MF-4SK membranes modified with silicon carbide and carbon nanotubes

The effect of hydrophobic silicon carbide nanoparticles and carbon nanotubes on the mechanical and transport properties of MF-4SK perfluorinated cation-exchange membranes has been studied. It has been shown that the modification of the membranes with a small amount of silicon carbide and carbon nanotubes enhances both their mechanical strength and selectivity of transport processes. An increase in the dopant concentration leads to deterioration of these parameters and the destruction of the membranes. This change in the properties is attributed to the implantation of nanoparticles into the hydrophobic membrane matrix, which results in a decrease in its elasticity.     

Structure and Fracture Resistance of Zirconium Alloys for Atomic Power Engineering

The effect of structure on the processes of deformation and fracture of zirconium alloys and on the characteristics of crack resistance and resistance to stress corrosion cracking of articles produced from them is studied. Methods for controlling fracture resistance by changing the structure of the alloys are considered. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 5, pp. 8 – 17, May, 2005.     

Experience in using ultrasonic and laser therapy in surgical diseases

Experience is presented gained with the use of ultratonotherapy, low-intensity laser radiation of infrared actions, and a number of drug electrophoreses in the treatment of 358 surgical patients over 1994-1996. A complex of combinations of different techniques common in physiotherapy has been designed with those of drug therapy during different phases of surgical disorders. Methods and complexes of the therapy treatments to be administered are submitted together with relevant indications. The proposed variants of complex physiotherapy make for earlier recovery, shorter treatment courses, longer remission.     

Streaming techniques: revealing the natural concurrency of the lattice Boltzmann method
