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” ...

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.

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.

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 ...

Human activity recognition (HAR) is a technique that somehow senses the human activities, analyzes the relevant information, and identifies the corresponding behaviors mode. This text introduces a kind of human physical activity recognition system based on frequency features.

Magnesium plays a role in the activation of various transporters and enzymes. The present study aimed to investigate the possibility of applying magnesium to enhance the eficacy of cisplatin which is still ranked as one of the major chemotherapeutic drugs for bladder cancer patients. Our indings reveal that magnesium could contribute to cisplatin-based chemotherapy bymoderately ...

Ferrite absorbing metamaterials designed with metamaterial structures can effectively broaden the absorption bandwidth of electromagnetic waves. The current mainstream approach is to compound ferrite with other materials to produce ferrite absorbing metamaterials with better performance.

The article presents the trends in the development of China's energy construction and analyzes the reasons for significant technological advances in this field of activity. Based on marginal analysis, the efficiency and sustainability of the functioning of China's energy field is shown.
