The bearing capacity and settlement of pile foundation were greatly influenced by the temperature variations of soil ground around pile foundation. This paper presented a short report about laboratory static load tests by model precast concrete piles (cross-section 4 × 4 cm and length of 60 cm) in seasonally freezing soil ground. The depth of frozen soil was 10 cm, temperature ...

An energy efficient technology and a method for the production of foam concrete products have been developed. They involve the use of solar energy in the process in order to reduce energy consumption for heat treatment, which allows to produce high-quality products with a low production cost with a daily production cycle. The technical and economic evaluation of the developed ...

The issues of digitalization of the mining industry, including open-pit mining, are considered. The issues of the use of semantic systems as an element of information flows, allowing to determine and select the right decisions in the process of mining management, in particular, in the mining of minerals by open mining, are covered. The article formulates requirements ...

A mathematical model of an electric drive of a centrifugal borehole pump is proposed for evaluating its energy consumption in operating conditions. The model is based on the use of minimum set of technical parameters of the pump, presented in the public data of the manufacturer. The correctness of the calculated formulas is confirmed by experimental data provided in the ...

In modern conditions the building can not only consume energy from the outside, but also produce its own. A new role has acquired such energy sources as the sun and wind. Energy saving in architecture follows from the requirements of regulatory documents and includes: the use of alternative energy sources, the installation of energy-saving equipment. Using examples of ...

The article evaluates current trends in the development of science and innovation in Kazakhstan. Analysis of scientific and innovation activities in Kazakhstan show that among the main sources of financing science there are almost no business representatives. An assessment of the current state of the national innovation system demonstrates that with the existing system ...

The article shows that the implementation of oil and gas companies will be implemented in many sectors of the global economy, including the main development sector-manufacturing industry. In Kazakhstan, “positive” experience has been accumulated in connection with the implementation of the oil and gas sector, because it is one of the main aspect of the global industries ...

Management and regulation of public debt for many years is an urgent problem of the functioning of the financial system of the state, as it is a component of the financial systems of the vast majority of countries. In this regard, the priorities and areas of the debt policy, in the framework of which the formation and servicing of public debt are gaining particular importance. ...

The article discusses the issues of financial stability of enterprises in unstable economic conditions. The authors propose a formal model of the gradual quantitative assessment of the financial stability of enterprises based on the use of regression equations with determination coefficients. The financial stability of enterprises is described by the indicators of their ...

The article presents measure to optimize the operating modes of power transformers in order to minimize losses of electrical energy. The influence of actual voltage and service life of power transformers on electric power losses is shown. It was proposed to determine the economic capacity of power transformers taking into account the indicated factors, as well as taking ...
