Water is an effective additive to fuel oil to reduce the concentration of soot in the gas phase

Mirlan MOLDOBAYEV | Kubat KEMELOV | Zarlık MAYMEKOV

Soot is one of the products of incomplete combustion of hydrocarbon fuels. It has the property of adsorption of active and carcinogenic substances on the surface of soot particles. In this regard, in burner equipment of medium and small power, it is required to develop and implement effective environmental measures to reduce emissions of soot particles. In this paper, the fuel oil-water-air system at a wide temperature range (T500-3000K) was studied and the ratio of gas-liquid flows (water content in fuel oil 5-15) at the maximum entropy of the system and the formation of soot in flue gases wa ...Daha fazlası

Asymptotics of the solution of the hyperbolic system with a small parameter

Asan ÖMÜRALİEV | Ella ABILAYEVA

Asymptotic study of singularly perturbed differential equations of hyperbolic type has received relatively little attention from researchers. In this paper, the asymptotic solution of the singularly perturbed Cauchy problem for a hyperbolic system is constructed. In addition, the regularization method for singularly perturbed problems of S. A. Lomov is used for the first time for the asymptotic solution of a hyperbolic system. It is shown that this approach greatly simplifies the construction of the asymptotics of the solution for singularly perturbed differential equations of hyperbolic type.

Investigation of chemical, sensory, and rheological properties of Kyrgyz ethnic fermented beverage from cereals during cold storage

Canıl İSKAKOVA

Maksym is a Kyrgyz ethnic beverage made from milled cereals such as wheat, barley, or maize, boiled in water, and then fermented using yeast and lactic acid bacteria as a starter culture. The aim of this study was to investigate the changes in the consistency and sensory properties of Maksym after industrial production during refrigerated storage. The acidity of the beverage increases and the total soluble solids decrease after 21 days. The amount of lactic acid bacteria (LAB) and yeast after production were 9.36 and 9.46 log cfu/mL, respectively. After 21 days it is indicated that the amount ...Daha fazlası

Antibiotic residuals removal via novel fabricated hydrogel from 2-hydroxyethyl methacrylate and sodium methacrylate

Urmat Coldoşbek Uulu | Nahit AKTAŞ

In this study, poly(2-hydroxyethyl-sodium methacrylate) (p(HEMA-SMA)) hydrogels were synthesized as a novel adsorbent to remove antibiotic residues from environmental samples. [p(HEMA-SMA)] co-polymers were synthesized by the free radical photopolymerization method. Synthesized hydrogels were characterized by different methods such as Fourier-transform infrared spectroscopy (FTIR), elemental and scanning electron microscope (SEM), and surface area calculations. The average size surface area of the synthesized hydrogels were 1.515 µm. Penicillin G (Pen. G) was used as the sample antibiotic for ...Daha fazlası

Biotechnological valorization of sugar beet wastes into value-added products

Acar Makambay Kızı | Ayçürök MACİTOVA

The sugar beet processing in the sugar production industry releases huge amounts of sugar beet pulp, lime residue, and molasses, which can be considered a valuable by-product as a source of cellulose, hemicellulose, and pectin. Sugar beet pulp is often used as a high-energy, low-protein supplement for ruminants to promote optimal rumen health and increase milk production. However, it cannot be used in large quantities and is thrown away, causing environmental pollution. Valorizing sugar beet processing wastes via biotechnological approaches into value-added products is cost-effective and eco-f ...Daha fazlası

A new approach for the bigeometric newton method

Ercan ÇELİK

In this study, quadratic convergent new bigeometric Newton's method (nBGNM) was developed. For this, the basic definitions and theorems of bigeometric analysis, which is one of the non-Newtonian analysis, were used. Using the bigeometric Taylor expansion, a convergence analysis of this new method was given. Also, the new bigeometric Newton method (nBGNM) was compared in detail with the geometric (multiplicative) Newton method (GNM) and the classical Newton method (NM). Keyword: bigeometric analysis; bigeometric newton method; quadratic convergence; bigeometric taylor expansion

Environmental pollution size of the Bishkek Solid Waste Landfill and treatment of generated leachate wastewater

Nurzat ŞAYKİYEVA

The disposal of municipal solid wastes (MSW) is one of the important issues today. The MSW is generally disposed of in a landfill. The disintegration of wastes in landfill generates the wastewater known as leachate and it became one of the budding environmental impacts. The landfill leachate seeps into natural ponds next to the Bishkek (Kyrgyzstan) landfill. The MSWs are dumped with an irregular landfill in Bishkek, and it has been observed that this situation creates many environmental pollution problems (air pollution due to the combustion of wastes and generated biogas, due to leakage of le ...Daha fazlası
