A new production technology is proposed for VT16 alloy fasteners. The destructive loads in fracture and shear are considerably greater than those of comparable mass-produced fasteners. The technological parameters and weight of the fasteners produced meet the requirements of aerospace engineering.

In the modern educational process aimed on preparing professionals in the applied areas, it’s crucial, along with purely professional training, to provide students both with solid theoretical background and help them to develop “soft skills” that will facilitate their smooth and efficient adaptation to the industry realities when they start their professional careers. In this paper we consider practical cases of acquiring soft skills through intensive field experience in two areas related to mathematical education.

Abstract Ingashi lamproite dykes are the only known primary sources of diamond in the Irkutsk district (Russia) and the only non-kimberlitic one in the Siberian craton. The Ingashi lamproite field is situated in the Urik-Iya graben within the Prisayan uplift of the Siberian craton. The phlogopite-olivine lamproites contain olivine, talc, phlogopite, serpentine, chlorite, olivine, garnet, chromite, orthopyroxene, clinopyroxene as well as Sr-F-apatite, monazite, zircon, armolcolite, priderite, potassium Mg-arfvedsonite, Mn-ilmenite, Nb-rutile and diamond. The only ultramafic lamprophyre dyke is composed mainly of serpentinized olivine and phlogopite in the talc-carbonate groundmass and is similar to Ingashi lamproites accessory assemblage with the same major element compositions. Trace element and Sr-Nd isotopic relationships of the Ingashi lamproites are similar to classic lamproites. Different dating methods have provided the ages of lamproites: 1481 Ma (Ar-Ar phlogopite), 1268 Ma (Rb-Sr whole rock) and 300 Ma (U-Pb zircon). Ingashi lamproite ages are controversial and require additional study. The calculated pressure of 3.5 GPa max for clinopyroxenes indicates that lamproite magma originated deeper than 100 km. A Cr-in-garnet barometer shows a 3.7–4.3 GPa min and derivation of Ingashi lamproites deeper than 120 km in depth. Based on the range of typical cratonic geotherms and the presence of diamonds, the Ingashi lamproite magma originated at a depth greater than 155 km.

The experience of using the LWD production complex of Research and Production Company VNIIGIS-ZTK LLC, which allows you to track the lithology and thickness of the layers in the direction of drilling, to predict the point of entry into the reservoir, to conduct the well on the most productive part of the reservoir, is considered.

This paper is aimed to find a connection between i-dimensional spaces (i=0,…, ‘n') and the long-range j-dimensional attractive forces (j=0,…, ‘m') creating these spaces. The connection is fundamental and unrelated to any processes going in the spaces being studied. A theorem is formulated and strictly proved showing in which cases the long-ranged attractive forces can form real spaces of different dimensions ( i=0,…,n). The existence of the attraction between masses is defined by divergence of the vector of interaction between masses. Weak anisotropic real spaces are studied by rotating an ellipsoid for (3 ζ)D-cases when its eccentricity e<<1. Such spaces cannot be in equilibrium, the time of their existence is substantially limited. The greater is anisotropy, the shorter is the lifetime of such substance. The latter cannot be in equilibrium, the time of their existence is substantially limited.

Prospects of oil and gas content of the Riphean deposits of the Nizhnyaya and Podkamennaya Tunguska interfluves from the point of view of the prerequisites for the formation of reservoir rocks, the presence of oil deposits and the conditions for reservoir preservation are considered. Based on a complex interpretation of seismic data and deep drilling wells, the geological map of the pre-Vendian erosion surface served as a basis for identifying zones of possible development of reservoirs in the Riphean deposits for the Baikit, Katanskaya and Severo-Tunguska oil and gas regions. A forecast is given for the distribution of hydrocarbon deposits by the phase composition in the Riphean complex

At any stage of development of subsurface resources there are uncertainties of geological and technological nature that cause economic risks for the subsoil user. The report describes the author's algorithmic approach, which makes it possible to objectively evaluate these risks and make balanced management decisions at all stages of studying and developing hydrocarbon resources. The suggested methodology includes interplay with geological and geophysical data bases, detailed hydrodynamic modeling of the field development processes, and also takes into account the complexity of the geological structure of the objects.

The requirements on preproduction and the control software for various digital machining systems (numerically controlled machine tools, robot manipulators, additive manufacturing equipment) in flexible production are considered. By analysis of existing programming languages for digital equipment, UNCL (Uniform Numeric Control Language) has been developed for standard representation of control commands. The use of UNCL in verifying program operation on a machining simulator is considered. Software for the translation of control programs (specified in CLDATA formats and in ISO code) to the invariant format of the universal language is described. The postprocessing of control software from the universal language into programs in commonly used digital control systems is also considered.

Summary The geological exploration consistency lies in the successive study of a sedimentary basin, an oil and gas accumulation zone, exploration targets, and than a field. Thus, as the knowledge is being gathered, the studied territory is repeatedly localised, geological approaches and criteria evolve, the exploration maturity improves, the uncertainty level decreases, and principally different management tasks are set. The economic appraisal, as a constitutive of the elaboration of corporate solutions, shall consider the specifics described. In particular, for two different types of hydrocarbon objects and geological exploration stages, there must be different objectives, tasks, methods, and sought indicators of economic analysis. The authors suggest a conceptual methodological approach to defining feasibility of diverse oil and gas projects and the conditions of cost-effective development, and consider its application on various scales: to a macroregion (southern Siberian Platform), separate highly promising zones within a macroregion (Baikit, Nepa-Botuoba, etc.), prepared and identified structures (Kapaevskaya and Katskaya-2 within the Verkhnekatangsky block), and a developed field. The authors conclude that feasibility study methods must be applied correctly in terms of methodology.
