Dynamic thermal methods and microprocessing units for measuring the rates and properties of material flows

A multifunctional measurement system utilizing a noncontacting, thermal-tracer primary detector is described. It provides for the automatic acquisition of information on volumetric and mass flow rates and the properties of fluid flows.Translated from Izmeritel'naya Tekhnika, No. 8, pp. 10–11, August, 1994.     

Calculation method for percolation thresholds in modeling porous and composite materials

A method is suggested for calculating percolation thresholds in two- and three-dimensional materials allowing for remote interaction and elongation of particles forming these materials. Calculated results are compared with known data. It is shown that it is possible to use the method when simulating elastic and plastic properties of porous materials.     

Nanoparticles and Their Effective Use in the Technology of Highly Concentrated Binding Suspensions (HCBS) and Refractory Castables. Part 1

General aspects (including terminology) related to the use of ultradisperse particulates (nanosystems) are discussed. The important role of nanoparticles in the technology of highly concentrated binding suspensions (HCBS) and refractory castables is emphasized. Using nanoparticles provides a route toward improving the rheotechnologic properties of HCBS and HCBS-based molding mixtures as well as the structure and service properties of the end product.     

On studying methods for cleaning dielectric oil for impregnation of high-voltage pulse capacitors with film dielectric

Methods for cleaning commercial T-1500 dielectric oil with different adsorbents are studied. The oil is intended for impregnation of high-voltage pulse capacitors with film dielectric.     

An experimental superconducting magnetic system with an adjustable winding inductance and a 5 MJ energy capacity

An experimental superconducting magnetic system (MS) with an energy capacity of 5 MJ and an output power of no less than 130 MW is described. The MS winding is sectioned in the axial and radial directions. Owing to sectioning in radial direction, the MS may be used as an adjustable inductance enabling the stabilization of the amperage. The adjustable inductance may also be used as an efficient instrument for leveling the ratio of the active and reactive power in electric mains intended for different purposes (transport, energy industry, and emergency systems).     

Complete analysis of ionic staining of glasses by transition-metal compounds

The data on the ionic staining of glasses are analyzed from the standpoint of ligand field theory. New information is added to the existing information on the staining of glasses by transition-metal compounds. Data on the structure of glass-forming melts and the conditions for the formation of staining complexes are presented. A possible mechanism for amber staining in glasses is discussed. __________ Translated from Steklo i Keramika, No. 5, pp. 7–12, May, 2007.
