Solid Fuel Chemistry | Year: 2017

The possibility of controlling the ash content of fuel based on a carbon/oxygen ratio taking into account variable carbon content out of the organic matter was demonstrated. An algorithm was proposed for the determination of the ash content with the use of a pulsed neutron method with the detection of gamma rays from inelastic neutron scattering on the nuclei of carbon, oxygen, and calcium with an instrumental correction for the variable chemical composition of the mineral matter of coals. The procedure was recommended for the operational quality control of coarse dispersed fuel whose chemical composition varies over wide limits. © 2017, Allerton Press, Inc.

Frequency-temperature spectra of the complex permittivity are studied for proton semiconductors and dielectrics using the methods of a quasi-classical kinetic theory of dielectric relaxation (the Boltzmann kinetic theory) in the linear approximation with respect to the polarizing field in the radio frequency range at temperatures T = 50-450 K. The effect of the quantum transitions of protons on the Debye dispersion relations is taken into account for crystals with hydrogen bonds (HBC) at low temperatures (50-100 K). The diffusion coefficients and the mobilities under electrical transfer of protons in the HBCs are constructed at high temperatures (100-350 K) in a non-linear approximation with respect to the polarizing field. © 2017 Springer Science+Business Media New York

The article focuses on the specifics of the development and implementation of a dual system consisting of a subsystem for designing production units' power supply and a subsystem of assessing knowledge of coal mine electrical services employees. The paper identifies quantitative and qualitative changes of recent years at the companies engaged in underground coal mining. Furthermore, the paper provides a rationale for the dual system and describes an algorithm for generation of a single database, which includes calculation subsystem database, subsystem database for knowledge assessment and a virtual simulator for assessing staff readiness to work with coalmines producing areas power supply. We consider testing algorithms (knowledge control), further training and authorization of coalmine electrical services personnel for maintenance, calculations, mounting, dismantling and adjustment of power supply systems of coalmine producing units. Moreover, we propose dual system's operating procedures and consider a beneficial impact due to introduction of the dual system. © 2016 IEEE.

Due to the reduced number of hours dedicated to General Physics within the undergraduate program, there is an evident need for new approaches to teaching the basics of physics. Authors formulated requirements for and developed a fundamentally new set of educational laboratory equipment. The emphasis is placed on analyzing the results of experiments, as opposed to the methodology and process of experimentation. Lab execution times are minimized. Equipment pieces are autonomous, mobile, do not require premises setup and are highly damage-resistant. Some equipment can be used for experiments related to different sections within the General Physics course. © 2016 IEEE.

Halloysite clay nanotubes loaded with corrosion inhibitors benzotriazole (BTA), 2-mercaptobenzimidazole (MBI), and 2-mercaptobenzothiazole (MBT) were used as additives in self-healing composite paint coating of copper. These inhibitors form protective films on the metal surface and mitigate corrosion. Mechanisms involved in the film formation have been studied with optical and electron microscopy, UV-vis spectrometry, and adhesivity tests. Efficiency of the halloysite lumen loading ascended in the order of BTA < MBT < MBI; consequently, MBI and MBT halloysite formulations have shown the best protection. Inhibitors were kept in the tubes buried in polymeric paint layer for a long time and release was enhanced in the coating defects exposed to humid media with 20-50 h, sufficient for formation of protective layer. Anticorrosive performance of the halloysite-based composite acrylic and polyurethane coatings have been demonstrated for 110-copper alloy strips exposed to 0.5 M aqueous NaCl for 6 months. © 2013 American Chemical Society.

In the paper there is studied stressed-and-strained state formed in a billet by fullering in a tool with movable elements. It is determined that compressing stresses prevail in the studied tool; they improve the quality of the processed billets. Even maximum main normal stresses have compressing characteristics at slight tensile stresses. Stressed-and-strained state was studied by using the computer simulation method which was performed in the DEFORM 3D software. The obtained results confirm the efficiency of the new tool in processing cylindrical billets. © 2016, Faculty of Metallurgy. All rights reserved.

Designs of multichannel belt-conveyor weighers are considered. A technique for verification of such weighers using a reference load is presented. It is shown that in the course of inspection multichannel belt-conveyor weighers may be represented by a combination of two-channel weighers without halting the technological process. © 2016, Springer Science+Business Media New York.

Interlaboratory comparisons need a reference value of the measurand to be assigned. It is necessary to have some procedure that allows to determine the reference value at a maximum number of participating laboratories results to be included into the determination and, at the same time, unreliable laboratory results must be disregarded. It is shown in the paper that this procedure can be implemented using a preference aggregation approach.


In the economy of the Republic of Kazakhstan there still continues orientation towards raw materials and dependence on the world raw materials markets conjuncture. The key causes of the low level of the economy competitiveness are related to the decoupling between science and production, insufficient financing of innovation projects, absence of the efficient mechanisms of bringing scientific-technical production to the level of goods, high capital consumption.Renunciation of the raw materials model requires modernization and simultaneous transition to the innovation economy, as Kazakhstan relates its constant stable growth, first of all, to the transition to the innovation way of development. Today Kazakhstan is actively forming a new economy which is being built on the present day knowledge and competitive innovations. Besides, the purpose of institutional transformations is the establishing of the market innovative-active subjects. However, till nowadays the program of reduction of home economy dependence of on raw materials does not give the expected results and until this key problem is left unsolved, it will effect negatively economy’s development, especially in case of the sharp worsening of the environment. Unconditionally, there are other domestic problems that will prevent from supporting a stable growth.Kazakhstan’s transition to the innovation type of development can be conditionally divided into two stages. The beginning of the first stage is connected with adoption of the Strategy of industrial-innovation development in 2003, formation of the institutional base and the key moments of the national innovation system. In 2010, having adopted the State program of forced industrial-innovation development of the country for 2010–2014 there began the stage of accelerated building of the innovation economy, strengthening of legislative and financial stimulation of the innovation activity.At present the efforts of the state innovation policy are aimed to, firstly, the development of innovation clusters and innovation environment, secondly, the increase of the innovation infrastructure efficiency, thirdly, the development of principally new system of scientific-technological developments’ commercialization.Up to 2015 the main priority trends of the state policy on the country’s forced industrialization will become realization of innovation-investment projects in traditional export-oriented sectors of economy. The main accent will be made on development of new instruments of the state-private partnership in the sphere of innovations development, as well as target technological programs for co-funding prospective research.Within the frames of the article there is shown the state role in development and support of the innovation sphere, the accent is made on the state regulation of Kazakhstan’s industrial enterprises innovation activity. © 2014, Kaunas University of Technology.
