INNOVATIVE WIND TURBINE

Rahmanov Valijon Turdaliyevich, Alijonov Jasurbek Rustambek o‘g‘li

An innovative wind turbine has a half-cylinder that aligns the vertical wind turbine with the direction of rotation of the rotating impeller. The function of the semi-cylinder is to direct the influencing wind onto the arm of the wings rotating in the direction of the wind. The semi-cylinder rotates completely on the windmill support, and a weather vane is attached to its rear. The wind roller function adjusts the rotating blades inside the half-cylinder in the direction of the wind.

MORPHOLOGY AND PROPERTIES JUTE FIBERS

Gafurov Adkhamjon, Korabayev Sherzod, Alimov Orif

Among all bast fibers, jute is one of the most significant and versatile fibers of commercial and technical importance. Jute, also a cellulosic fiber, ranks next to cotton in terms of production. Jute is an annual herbaceous plant mainly cultivated in the equatorial, the tropical and the sub-tropical zones. Jute plays a vital socio-economic role in producing countries. About 12 million farming families, mainly in South East Asia, are dependent on this crop. Out of over 30 important species belonging to the genus Corchorus, only two – C. capsularis commonly known as ‘White jute’ and C. olitorius known as ‘Tossa jute’ – are utilized for fiber production on a commercial scale. This chapter discusses almost the whole gamut of jute starting from its origin, history, agro-climatic condition and production area, economic importance, botanical description, different stages of cultivation, fiber extraction, fiber quality and grading, fiber morphology, structure, chemical composition, properties, products, traditional/unconventional uses, etc. In addition, the chapter briefly describes the environmental advantages and the socioeconomic impacts of jute along with its future potential.

Butaboyev Alimardon Alimjonovich, Qilichev Sunnatillo Toxir o‘g‘li

In practice, there are such problems that the simple differential equations taken as a mathematical model or their system of integration of the interval are solved not at all points, but at one or several given points (for example, at the last point of the interval). One of the most common problems of this type is the problem of searching for attractors of dynamic systems (attractor is an English word meaning aspiration to a single point).
