Saint Petersburg, Russia

The National Mineral Resources University, formerly known as the Mining Institute, is Russia's oldest technical university, and one of the oldest technical colleges in Europe. It was founded on October 21, 1773, by Empress Catherine the Great, who realised an idea proposed by Peter the Great and Mikhail Lomonosov for training engineers for the mining and metals industries. Having a strong engineering profession was seen by many Russian rulers as a vital means of maintaining Russia's status as a great power. As historian Alfred J. Rieber wrote, "The marriage of technology and central state power had a natural attraction for Peter the Great and his successors, particularly Paul I, Alexander I and Nicholas I". All three had had a military education and seen the achievements of the engineers of revolutionary and imperial France, who had reconstructed the great highways, unified the waterways and erected buildings throughout Europe in a more lasting tribute to the French than all of Napoleon's victories.Though located in St. Petersburg, the University is on a federal rather than local level, and has partnerships with global oil, gas and mining companies and governments. Its museum is home to one of the world's finest collections of gem and mineral samples and the university building is a Neoclassical masterpiece by Andrey Voronikhin. Wikipedia.

The energy spectra of fast electrons resulting from pair collisions between metastable atoms and from collisions of the second kind with electrons are observed in the afterglow of a helium-filled microplasma collisional electron spectroscopy (CES) detector at a pressure of 5-40 Torr. It is demonstrated that impurities present in the main inert gas can be detected and their composition can be determined using a planar double-electrode detector in which the cathode simultaneously serves as an analyzer of electrons in the afterglow. © 2012 Pleiades Publishing, Ltd.

Geoelectrical methods measure resistivity and induced polarization (IP) effects in the subsurface. The differentially normalized electromagnetic method (DNME) detects geochemical alteration zones due to anomalous electrical responses which are often located above a hydrocarbon accumulation. Leakage above a non-perfect top seal is postulated to change the pH in the overlying sediments where a shallower mobility barrier is encountered. Epigenetic pyrite mineral growth is stimulated when iron and sulfur ions are available. Leakage and mineral growth are modelled by mathematical formulae assuming diffusion migration through the overburden. Effects of time and tectonic faulting are examined. Pyrite is highly polarizable and easily detected by an electrical IP survey in the field, whereby a current is introduced into the ground and subsequently turned off. Decay of the potential difference over the receiver electrodes is monitored in time. Special parameters facilitate detection of IP anomalies related to the presence of hydrocarbons. An inverted electrical depth model is computed using the Cole-Cole formula. The impact of geo-chemical modelling and predicted epigenetic mineral growth is demonstrated for the Severo-Gulyaevskaya dataset (Siberia). The overall DNME track record shows a reduced risk attached to hydrocarbon prospects, with a more reliable ranking at reasonable costs. © 2012 EAGE/Geological Society of London.

Geology of Ore Deposits | Year: 2010

Mineralogical indications of high-pressure crystallization of Li-F granites from Russia, Kazakhstan, and Mongolia are discussed. Syngenetic deformation of minerals (protoclasis) in these rocks has been revealed and described for the first time. A possible cause of the effect of high pressure on the solid phase during its crystallization from melt is considered. A progressive increase in pressure and manifestation of fluid overpressure in the course of crystallization is established. It is suggested that the idea of overpressure stated by V. S. Sobolev and N. L. Dobretsov may be applied to rare-metal magmatism. © 2010 Pleiades Publishing, Ltd.

The most widespread inorganic pigments are red iron oxides. Production of red iron oxide pigment based on haematite ores of the Yakovlevskoe deposit is promising and it makes it possible to satisfy the demand for high quality and inexpensive pigment. A waste-free scheme is developed for separating iron ore into two types, i.e., red (pigment) and metallurgical. The technology involves ore crushing, fine grinding in a ball mill and product classification. © 2010 Springer Science+Business Media, Inc.

The paper examines the application of information fragments to the development of computer-aided theoretical courses and training tasks as part of computerized training tools. State-of-the-art web-oriented and associated technologies used in combination with data warehouses of enterprises are considered as a basic method for designing training tools. Generalized structure of training courses and attributes of typical information fragments are described. © 2013 Pleiades Publishing, Ltd.

Ceramic samples based on ZnO-Nb2O5-TiO2 compositions have been prepared using solid state ceramic route. The work was carried out over a wide range of initial ZnNb2O6 and Zn0.17Nb0.33Ti0.5O2 compounds concentration. The crystal structure and microstructure developments were studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was shown that the phase compositions of the samples present itself a columbite type and mixture of two phases-solid solutions of columbite and rutile types.The sintering behavior, permittivity, its temperature coefficients and quality factor had been characterized for ceramic samples in depending on compositions. The permittivity of the samples in this system is within the limits from 24 to 80, τe{open} from 150 to -560ppm/°C. For the samples with τe{open}~0, e{open}r~43.8 and Q·f=35000GHz at f=9GHz. The comparatively low sintering temperature (≤1080°C) and high dielectric properties in microwave range make these ceramics promising for application in electronics. © 2010 Elsevier Ltd.

A combined method for numerical computation of the electromagnetic field in induction-heating systems is proposed and used. The method consists in a combination of methods of integral equations for the computation of the electromagnetic field in the area outside the load and methods of finite elements or finite differences for the computation of the electromagnetic field inside the load. A method of simulation of electrotechnical systems with simultaneous solving of circuit and field problems is proposed based on this method. Using the example of induction-heating devices, an external problem associated with the computation of circuit inductors, power supplies, and balancing capacitors and an internal problem related to the computation of the electromagnetic field and internal heat sources inside the load are formulated. The simulation of induction heaters is considered taking into account features of thyristor frequency converters with a parallel inverter. © 2014, Allerton Press, Inc.

The repeated isotopic and geochemical study of zircons of the eclogite from Stolbikha Island (Gridino settlement area) allows one to interpret the U-Pb age value of about 2700 Ma by central parts of zircon grains as a magmatic event time, probably rejuvenated to a degree by intense manifestation of the eclogite metamorphism of about 1880 Ma age. The Svecofennian high-pressure metamorphism caused a partial recrystallization of zircons of magmatic origin and the appearance of their rims showing typical geochemical characteristics of eclogite zircons. © 2011 Pleiades Publishing, Ltd.
