The millipede fauna of the Stavropol Territory, northern Caucasus comprises at least 19 species; 12 of them are new to the regional list, including two new to the fauna of Russia: Brachydesmus assimilis Lohmander, 1936 and Cylindroiulus arborum Verhoeff, 1928. Faunistic records of all these species in the Territory are presented and mapped. © 2014 ARTHROPODA SELECTA. Source

Determination of particle size distribution of the magnetic colloids according to the static and dynamic light scattering and magnetic birefringence were produced. Shown that the magnetic colloids with a low concentration of the solid phase are characterized by steady bimodal distribution, including individual nanoparticles with a size of 10-20 nm and aggregates of particles with a size of 40-80 nm. © 2014 Sumy State University.

In modern conditions commercial banks expand the list of services to clients with various methods. One of new, unoccupied segments of the banking market, having the name of blue oceans, is the customer service proceeding from their gender differences. The priority should be given to women as they are more loyal in a choice of banking products, accept considerable part of finance solutions, pay a large number of accounts, manage family budgets. In article the directions of perspective banking servicing of women are characterized, world and Russian experience is considered. Source

The peculiarities of scattering and extinction of light by colloids with different concentrations of magnetite nanoparticles are investigated. The light absorption effect on spectral dependencies of optical density of magnetic colloid are observed. According to dynamic light scattering experiments, particle size distributions for samples with different concentration of nanoparticles are defined. © 2015 Sumy State University. Source

The optical properties of colloidal solutions of nanosized magnetite particles in kerosene were studied by optical methods (birefringence and light scattering). The data on the birefringence kinetics in nonstationary magnetic fields is used to determine the size distribution of magnetite particles and aggregates. It is shown that the particle size distribution essentially depends on the type of magnetic moments of the particles and aggregates. Static and dynamic light scattering experiments confirm the conclusion about the existence of a significant fraction of nanoparticles in the form of aggregates with sizes of several tens of nanometers. © (2015) Trans Tech Publications, Switzerland.
