Theoretical description of electric fields in three-dimensional multipole ion traps.

In this paper, the principle of forming the spatial distribution of the potential in multipole three-dimensional ion traps of a general type is considered. A matrix method for describing the electric fields in ion traps for the th order of multipole is proposed. Typical electrode geometries for hexapole and octupole traps are considered.

Nanoscale Engineering of Inorganic Composite Scintillation Materials.

This review article considers the latest developments in the field of inorganic scintillation materials. Modern trends in the improvement of inorganic scintillation materials are based on engineering their features at the nanoscale level. The essential challenges to the fundamental steps of the technology of inorganic glass, glass ceramics, and ceramic scintillation materials are discussed.

Effect of Engineered Nanoparticles on Enhancement of Composite Properties Relevant to Oilfield Applications.

Materials with enhanced properties permitting operations under increasingly harsh conditions such as high pressure, high temperature, high salinity, and sour environments are in critical need for the oil industry. The recent progress in composite materials has been facilitated by engineered nanoparticles dispersed or in situ generated in different matrix media. The cases representing examples considered in this paper include elastomers filled with carbon nanotubes, both in as-received and surface-functionalized compositions; metal matrix composites with added diamond nanoparticles; and scintillating glass ceramic nanocomposites.

The efficacy of a brief intervention in reducing hazardous drinking in working age men in Russia: the HIM (Health for Izhevsk men) individually randomised parallel group exploratory trial.

Background: Russia has particularly low life expectancy for an industrialised country, with mortality at working ages having fluctuated dramatically over the past few decades, particularly among men. Alcohol has been identified as the most likely cause of these temporal variations. One approach to reducing the alcohol problem in Russia is 'brief interventions' which seek to change views of the personal acceptability of excessive drinking and to encourage self-directed behaviour change.
