In this paper, we construct exact traveling wave solutions of the loaded Korteweg-de Vries and the loaded modified Korteweg-de Vries by the functional variable method. The performance of this method is reliable and effective and gives the exact solitary and periodic wave solutions. All solutions to these equations have been examined and 3D graphics of the obtained solutions have been drawn using the MATLAB program. We get some traveling wave solutions, which are expressed by the hyperbolic functions and trigonometric functions. The graphical representations of some obtained solutions are demonstrated to better understand their physical features, including bell-shaped solitary wave solutions, singular soliton solutions, and solitary wave solutions of kink type. Our results reveal that the method is a very effective and straightforward way offormulating the exact traveling wave solutions of non-linear wave equations arising in mathematical physics and engineering.

The article presents data on the substantiation of a new design of gaskets for saw gins, characterized by a lightweight type and a composite structure of individual steel elements (disk with splines, rim), welded after preliminary assembly.
The steel structure of the inter-saw gasket, as shown by experimental studies on axial compression, in contrast to aluminum design, is characterized by high strength, less permanent deformation, increased hardness and the ability to maintain performance for a long time under repeated operation without violating the technological conditions of ginning.

Today, with the development of the construction industry, the demand for cement is also increasing. In increasing the volume of construction, cement is one of the resources available at the price of finished objects is achieved through cost reduction due to the use in the construction of modern high-quality building materials and products with lower energy consumption and with improved characteristics. Of particular importance is the production of effective cements based on industrial waste. On a global scale, special attention is paid to the development of new compositions of cements that increase the fire resistance of building structures and the most important task of research in this direction is the development of compositions based on industrial waste for Portland cement. When developing composite additives and based on them new compositions of highly effective composite Portland cement, in this direction it is necessary to substantiate a number of the following scientific solutions, in particular: development of new methods for the production of effective types of building products based on composite additives; development of new compositions for the production of nanocements with the participation of secondary raw materials; increase of concrete strength indicators on sulfate-resistant cements; optimization of the composition of raw materials in obtaining energy saving clinkers and cements; modernization of production technologies for white and decorative Portland cement; to increase the production of auxiliary cements, the use of alternative sources of active mineral additives and filler additives.
