One of the main components in the production of building materials is silicon, and an increase in the production of building materials means an increase in the number of workers engaged in their processing. Silicon is a brown powder or gray crystals. It is a part of sandstone, graphite, sand, coal mine waste rock, molded earth and porcelain pieces. Silicon is also one of the main components of dust in many industries, especially porcelain and abrasive. Silicon dioxide is a component of quartz, quartz and other materials. Human inhalation of silicon-containing dust leads to the development of silicosis, which manifests itself in the form of pulmonary fibrosis and increasingly impairs their function.
This study delves into the intricate dynamics of bean pod production by investigating the effects of varying doses of silicon, nitrogen, and molybdenum. Employing a comprehensive experimental approach, the research aims to unravel the optimal conditions for maximizing bean pod yield. Results from controlled experiments showcase the nuanced interplay between these essential elements and their impact on the growth and development of bean pods. The findings contribute valuable insights for agricultural practitioners seeking to optimize cultivation practices and enhance bean pod production in a sustainable and efficient manner.
In this paper problems of chemical and physical activation of local raw materials caoline and bentonite, and textural characteristics of high silicon zeolites and surface morphology were studied. The effect of the activation method of caoline and bentonite on the colloidal and sorption capacity was also studied. During the studies, the heat of wetting, adsorption linked water content and effective relative surface area were determined. Calculated distribution of pores by cycles (loops) of isothermal hysteresis r ≈ 8.5 nm. The volume of porosity of the sorbent when the capillaries were filled with water was determined as Vn= 0.135 cm3/g.
This review was done in Totally Randomized Plan with three replications. It was discovered that silicon (Si) supply levels essentially expanded the quantity of panicles, number of filled grains/panicle, 1000-grain weight and grain yields per pot. The most extreme grain yield 46.50 g/pot acquired from 10 g for every pot Si application level. In fine it was seen that wise stockpile of silicon altogether impact development, chlorophyll content and yield possibilities of rice.
In this study, the basic thermoelectric properties of granulated silicon with alkali metal atoms were studies in the process of temperature change. When analyzing the changes in the Seebeck coefficient (a), electrical conductivity (s) and thermal conductivity (c) under the influence of temperature, which are the main thermoelectric parameters.
The article discusses the physical processes, the related temperature dependencies of conductivity and the Zeebek coefficient in granular silicon and the influence of alkali metal atoms on them at a temperature of 300 K to 800 K. that the conductivity and Zebeck coefficient do not depend only on temperature, it depends on the crystal structure at the boundary of the two contacting regions, and the development of recombination centers in them with an increase in temperature. In the process of temperature growth, desorption of alkali metal atoms is observed, which leads to structural inhomogeneities of crystal lattices at the border of two contacting regions and at the same time increase in structural heterogeneity of crystal lattices of the desorption layer of alkali metal atoms, lead to electron scattering, which leads to a change in sign.
Clinical characteristics are given for 47 patients with pneumococcal pneumonia at the age from 1 to 7 years. Data analysis showed that pneumococcal pneumonia is more common in children under 3 years of age (42.5%). The use of modern test systems immunochromatographic test (Binax NOW S.pneumoniae test) along with the bacteriological method increases the etiological interpretation of pneumococcal pneumonia in children. The activation of neutrophils and the release of endogenous antimicrobial granules from the granules, aggravate the course of pneumonia, promote longer peptides (alpha defensins and cathelicidins) in the blood plasma, which locally protect the epithelial cells of the respiratory tract, continuing and often becoming one of the factors of mixed infection
The results of determining the strength of granules, hygroscopic point, sorption kinetics of water vapor and sorption moisture capacity of NS-fertilizers obtained by mixing melt ammonium nitrate with powdered natural gypsum (PG) and (NH4)2SO4.
The work carried out systematic research to create a technology for restoring the original properties of used oils. Adsorption purification of waste oils using the bentonite-vermiculite method was carried out. based on the use of the ability to retain oily contaminants penetrating through the outer surface and internal capillaries - the pores of the sorbent granules.
This article presents the results of examination of horses for helminthiasis in Ellikkala district. The average incidence of helminth infestation in the examined horses was 6.6%, stronglidiosis -6.6%, and parascaridiosis -20%. The overall infestation with helminths averaged 33.3 percent. “Panafenb”, a 22.2% drug for helminthiasis in horses, was found to be effective when given orally (per os) in the form of granules to horses in the amount of 1.0 g per 34 kg of live weight.
Starch consists of two types of molecules namely, amylosse and amylopectin .Amylose, a linear chain polymer constitutes about 20% of starch. It is more soluble in water, soluble in hot water but does not form gel while amylopectin is a branched chain polymer that constitutes about 80% of the starch. It is less soluble in water, soluble in hot but forms gel, hence the need for modification. In this study, Cassava starch was modified with distilled water, glycerol and vinegar. The cassava starch, distilled water, vinegar and glycerol were all weighed in required proportions into the beaker. 50g of cassava starch was weighed into a beaker, 10mls of vinegar was added. 20mls of glycerol was also added. The resulting mixture was thoroughly stirred to form a uniform suspension, the suspension was heated, and it was continuously stirred to avoid coagulation with increasing viscosity until gelatinization was achieved at about 100°C. The gel was spread on a smooth, hard surface and mechanically pressed to form sheets. The sheets were air dried to cure for 72hrs to 5% moisture content. The sheet was subjected to tensile test. Water was used as a solvent to first get the biopolymer (starch) into solution. When the solution was heated, the water helped the starch molecules to become disrupted and disordered (denatured). The reduction of starch hydrogen bonding was achieved in the presence of water. Water diffused into the starch granules and hydrogen bonds breaking down the intermolecular bonds of the starch molecules. Water helped the starch molecules to become disrupted and disordered. When the starch was heated with water, water interacted with hydroxyl
The main purpose from this paper, in semiconductor technology silicon oxide is to study notable of the surface and catalysis process. As a result, cluster fragmentation processes, we obtained information about the emission of the clusters and the chemical and physical properties of the clusters. We found during the study that oxide clusters are heterogeneous clusters. In heterogeneous clusters, the bonds in the main chain are different from the bonds in the side chain, as in organic polymers. We tried to prove on the basis of the analysis of experimental data that the formation, excitation and molecular decomposition of SinO2n + 1Hk- (k = 1-3) cluster ions are based on the model of the combinatorial synthesis mechanism.
