Systematic Types of Fungi of Allocated and Determined Types from Decorative Flowers in Conditions Region Tashkent

For the first time, the introduction and adaptability of the Felionopsis variety, an orchid (Orchidaceae J.) imported from Malaysia, was analyzed. When using 0.4 l/mg of BAP (quinitine) as part of a nutrient medium for growing orchids in vitro from seeds and vegetative parts, the number of flowers at the 18th month was 10 or 2 times compared with the preparation Trichoderma vrayde and it was found that it is possible increase activated carbon by 2.5 times. It has been proven that up to 60% of explants can be obtained in 2 weeks using the MS+1NAA+1BAP hormone when cultivating an orchid flower stem in vitro.

“…So, the famous synthesis of hydrocarbons from carbon monoxide and hydrogen showed, which was later called the Fischer-Tropsch synthesis. A mixture of CO and H 2 in various proportions, called synthesis gas, can be easily obtained from carbonaceous or other coal raw materials [2].…”

Study of the process of obtaining hydrocarbons on the basis of synthesis gas and the fischer-tropsch synthesis reaction

The Fischer–Tropsch process is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300°C (302–572°F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons. In the usual implementation, carbon monoxide and hydrogen, the feedstocks for FT, are produced from coal, natural gas, or biomass in a process known as gasification. The process then converts these gases into synthetic lubrication oil and synthetic fuel. This process has received intermittent attention as a source of low-sulfur diesel fuel and to address the supply or cost of petroleum-derived hydrocarbons. Fischer-Tropsch process is discussed as a step of producing carbon-neutral liquid hydrocarbon fuels from CO2 and hydrogen. The article is devoted to the use of synthesis gas as an alternative petroleum raw material for obtaining artificial liquid fuels, hydrocarbons (Fisher-Tropsch synthesis) and aldehydes (hydroformylation or oxo-synthesis). The mechanisms of the considered reactions are discussed.

“…As a result of frequent stops of the plow cleaning unit, the quality of plowing significantly worsens, productivity decreases and machine operators ' fatigue increases. Therefore, machine operators often work without preplows, which, although it reduces the clogging of plows, significantly worsens the embedding of crop residues in the soil [3][4][5].…”

Investigation and substantiation of the parameters of the plow body angle lift

Currently plowing fields from under various agricultural crops is carried out with reverse plows in Uzbekistan. Their use can dramatically reduce labor and money costs for conducting current and capital field planning. With the supply of energy-rich wheeled tractors to the Republic of Uzbekistan, one of the most effective ways to increase the productivity of plowing units at present is to increase the plow's working width by increasing the number of housings. Increasing the number of hulls on revolving ploughs, equipped with pre-ploughs, this leads to a sharp increase in the metal and energy consumption of ploughs, since the latter have a double number of working elements. Therefore, an important role is played by the optimal placement of plow bodies along the plow course and the maximum reduction of distances between them, when using angle plates on the bodies instead of traditional pre-plows. The article discusses experimental influence of the angle-lift radius of curvature, the installation height, and the installation angles in the longitudinally-vertical and transversely-vertical planes on the traction resistance of the hull and the depth of embedding of plant remains was studied by MRI.
