3D modeling was carried out to determine the optimal diameters of grinding wheels for backing the back surface of the tooth of a disk gear cutter with a module m = 1...16 mm. A linear relationship has been established between the height of the tooth, the angle of the flute of the cutter and the diameter of the grinding wheel. It has been proven that the formation of a “saddle” ...

For regenerative medicine, a paste for 3D printing of tissue-engineered frames based on sodium alginate and hydroxyapatite has been obtained, which combines the advantages of both materials. The optimal content of hydroxyapatite in a paste based on alginate gel is 25–33 %. With an increase in the concentration of alginate in the gel from 3 % to 5 %, the rheological properties of ...

Clustering analysis is fundamental for determining dominant discontinuity properties in rock engineering. This study proposes an improved netting algorithm for identifying discontinuity sets based on multiple discontinuity properties. The new method is believed to be a potentially useful tool for rapidly obtaining dominant discontinuity sets in rock engineering.

China and Belarus are a comprehensive strategic partnership of coordination in the field of diplomacy. The two countries also have natural advantages in trade exchanges and have huge potential for development. China and Belarus have different resource advantages, and the trade between the two sides has good economic and trade complementarity. ctively expand the fields of economic ...

Since the COVID-19 pandemic, cooperation between China and Belarus has been affected, especially in tourism. Currently, the two sides can build digital tourism cooperation to promote development. This paper analyzes the previous ways of cooperation and proposes digital ways of enhancing tourism cooperation and the problems that need to be solved.

Green building is one of the important contents of sustainable development, and the research and application of BIM technology plays an important role in realizing the life cycle of green building, this paper analyzes the integration of BIM technology and sustainable development – green building and explores the significance of BIM technology to the sustainable development of ...

In this article there is a completed description of a calculation of a reinforced concrete construction with finite element modeling located in soil. The calculation was carried out on an electronic computer complex using software. Physical and mechanical properties of soil and reinforced concrete construction were taken into account.

In recent years, e-commerce has flourished in China and even the global trade market, and has been integrated into every corner of our lives. With the rapid development of e-commerce, the prevailing “20–80 law” in economics has been well verified. Many economists believe that the 20 % of customers who create 80 % of corporate profits are the true value of corporate customer loyalty.

The development of organic farming around the world and in Belarus in the last 10–15 years has shown the importance of studying and introducing biological methods for combating plant diseases. For this, studies of various microorganisms are carried out throughout the world, which can become the basis for modern plant protection products that do not damage the environment and human ...

Garbage enzymes rationally using of waste from fruits and vegetables are rich in nutritionally active substances and microbial groups and positively affect the growth of agricultural crops. In this project, by studying the effect of different classes of garbage enzymes on plant growth at different concentrations, and study on molecular biological mechanism will provide sufficient ...
