Socio-Political, Spiritual And Moral Views Of Zainiddin Vasifi, Ravshanbek Jalilovich Mahmudov, Temur Bobir Ogli Abdullaev
Bulletin of Gulistan State University
Zainiddin Abdujalil Vasifi, a young contemporary of Alisher Navoi, lived in the late 15thand early 16thcenturies. It is known from the sources that Zainiddin Vasifi wrote a number of works, but his work "Badoe ul-Wakoe" ("Rare Events") was translated from Persian and has come down to us. The thinker provides valuable information about the social and political life of Khorasan, the cultural life of Herat, Alisher Navoi, Hussein Vaz Kashifi, Fakhriddin Ali Safi, Hussein Boykaro. This work presents valuable information about the cultural life of the 16th century, the spiritual heritage of scientists, worldview, morality, human qualities of people of …

The visual arts used in history lessons have their own requirements, just like other history textbooks, and the process for fulfilling these requirements is different. The visual arts used in history lessons solve a number of problems. The bulk of the teaching of history is conducted in the form of lessons. That is, students receive the main content of educational materials in the classroom, that is, during the lesson. While the use of historical documents and art collections with historical themes in history lessons is illustrated through the teacher's speech, visual aids provide students with a vivid and clear picture …

Prior to sowing seeds of agricultural crops, awareness of the thermal, water, and light regimes of the land is of great importance. In this article, we studied the thermal and temperature conditions of flat and inclined lands through the heat transfer equations in the soil. At the same time, the temperature invariance at a certain depth from the soil surface was mainly obtained, on the basis of which a formula for calculating the soil temperature from the sediment was derived by the method of harmonic analysis. In addition, formulas for flat Land and temperature regimes of 10˚, 20˚, 30˚ slopes …
Features Of Liquid-Phase Epitaxy Of (Gaas)1-X(Znse)X Solid Solution From The Tin Solution-Melt, Amin Safarbaevich Saidov, Dadazhon Valikhanovich Saparov, Shukrullo Negmatovich Usmonov, Kurban Gulmuratovich Gaimnazarov, Mansurbek Kilichovich Sultanov

Layers of (GaAs)1-x(ZnSe)x (0 x 0.80) molecular substitution solid solutions with a smoothly (but not monotonically) varying composition on monocrystal GaAs (100) substrates were grown by liquid-phase epitaxy from a limited volume of a tin solution-melt. Based on the results of the solubility of GaAs, ZnSe in tin and the phase diagram of binary systems Ga-Sn, As-Sn, Zn-Sn and Sn-Se, it is shown that binary compounds in the tin solvent at temperatures of 650-750°C are below the melting point of the corresponding materials are found mainly in the form of GaAs and ZnSe molecules. Moreover, in the temperature …

Applications Of The Improper Integrals To The Physical Process, Husanboy Norjigitov, Iroda Dustnazarova
Bulletin of Gulistan State University
Studying the magnetic field of current, Bio and Savar came to the conclusion that the force with which the current acts on the magnetic charge can be considered as equal to the forces, as if coming from individual infinitesimal current elements. In this paper, we study the physical applications of definite and improper integrals. It also provides an in-depth analysis of the famous Bio-Savard Laplace's law in physics. It was calculating that this is the power acting on the current through l long conductor and the gravitational attraction of the body. Various descriptive schemes were used to describe computational processes. …
Automodeled - Solution To The Problem Of Ground Water Dynamics In The Presence Of Nonlinear Evaporation, Kengash Jamuratov
Automodeled - Solution To The Problem Of Ground Water Dynamics In The Presence Of Nonlinear Evaporation, Kengash Jamuratov
Bulletin of Gulistan State University
The problem of determining the level of groundwater near reservoirs, taking into account evaporation from the surface of groundwater, is reduced to a boundary value problem with an unknown boundary for a parabolic equation. The condition for the problem (motion) to be self-similar is established. A problem with an unknown boundary is distinguished and investigated, which differs from the well-known problems of Stefan, Verigin, Florin. The problem under consideration describes the filtration process near new canals and reservoirs, taking into account evaporation, which is a nonlinear finite function of time and groundwater level. A separate method of linearization of the …

This article proposes a simple and rapid method for the spectrophotometric determination of iron (III) using a physiologically active compound - the mono ammonium salt of glycyrrhizic acid (MASGA). The spectral characteristics of the MASGK-Fe (III) complex - absorption maxima (λmax = 440nm) and the actual molar extinction coefficient (ε = 3,425 × 102) were determined. The experimental results showed that when using a universal buffer solution, the complex compound had the maximum optical density. Therefore, in subsequent studies, a universal buffer solution with pH = 5 was used. The experimental results showed that the optical density of the complex …

In irrigated lands of the Aral Sea Basin, salt-affected areas are increasingly rising and this negatively impacts agricultural development and food security in such countries located in the basin. Drivers, increasing salt-affected areas, are assumed to be climate change, unregulated high groundwater levels and its increased mineralization, poor functioning of the collector-drainage system, and insufficient compliance with agro-technical requirements. These drivers, in turn, lead to the withdrawal of arable land from agricultural purposes and a significant drop in crop yields. This is especially the case in the irrigated areas of the lower reaches of the Amu Darya and Syr Darya …
