Ordinary differential equations with power boundary layers

Asan ÖMÜRALİEV | Ella ABILAYEVA

The regularized asymptotics of a solution of the Cauchy problem for systems of singularly perturbed ordinary differential equations is constructed. It is shown that a power boundary layer appears in such problems in addition to other boundary layers.

Serum biochemical reference values of Kyrgyz donkeys (Equus asinus)

Nurcamal ÖMÜRZAKOVA

The aim of the study was to determine the some serum biochemical values of Kyrgyz donkeys and present the reference values. Fifty (50) healthy donkeys in different ages (6–24 months, 2–15 years, and > 15 years old) and gender (male and female) were clinically examined and blood samples were taken. Serum triglycerides (TG), creatine phosphokinase (CPK), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), total bilirubin (TBil), total protein (TP), albumin (Alb), creatinine (Creat), urea (Urea), amylase (Amy), lipase (Lip), calcium (Ca), magnesium (Mg) ...Более

The Optimal Vector Control for the Elastic Oscillations Described by Fredholm Integral-Differential Equations

Elmira ABDILDAYEVA

In this paper, we investigate the nonlinear problem of the optimal vector control for oscillation processes described by Fredholm integro-differential equations in partial derivatives when function of external sources nonlinearly depend on control parameters. It was found that the system of nonlinear integral equations,which obtained relatively to the components of the optimal vector control, have the property of equal relations. This fact lets us to simplify the procedure of the constructing the solution of the nonlinear optimization problem. We have developed algorithm for constructing the s ...Более

The web-based learning environment in general physics course in a public university in Kyrgyzstan

Gülşat MUHAMETJANOVA | Azat AKMATBEKOVA

This study was conducted to see the attitudes of students toward web-based learning environment in General Physics course. The study was conducted in a public university in Kyrgyzstan in 2018. 144 students from the faculty of Science and Engineering participated in the study. Online questionnaire was completed online at the end of the spring semester 2017-2018. In addition, in-depth interviews with 12 students were conducted. Results showed that students’ success in online Physics course depends on gender and academic major of students. Factors, that were defined in this study: advantages over ...Более

EVALUATION OF ALUMINUM STRESS INDUCED ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES IN ROMAN NETTLE

İbrahim İlker ÖZYİĞİT

In this current work, Roman nettle (Urtica pilulifera L.), a traditional medicinal plant that is very common and widespread species throughout Asia, Europe, and Northern Africa, was used as a model plant to investigate changes in antimicrobial activity following the application of aluminum stress. U pilulifera seedlings were grown in growth-room conditions and 0, 100, and 200 M AlCl3 were applied to the plants together with Hoagland solution (20 ml) for two months. The antimicrobial activities were tested against nine strains of bacteria (Salmonella sp., Staphyllococcus aureus, Escherichia col ...Более

ECOPHYSIOLOGICAL PROPERTIES OF TURKISH ENDEMIC CENTAUREA CONSANGUINEA DC

İbrahim İlker ÖZYİĞİT

This physiological and ecological study was performed on Centaurea consanguinea DC. to acquire information about certain characteristics (bioclimatic, edaphic, topographic, biotic etc.) of its habitat and distribution in Turkey, determine the requirements for germination, explore the soil-plant relations and obtain data on certain aspects of its population biology. Plant and co-located soil samples were collected from Amasya and Havza District (Samsun) in Turkey using standard methods. Various analyzes were employed for determining of physical, chemical and biological properties of the plant s ...Более

DNA fingerprinting and assessment of some physiological changes in Al-induced Bryophyllum daigremontianum clones

İbrahim İlker ÖZYİĞİT

Aluminum (Al) is one of the most important stress factors that reduce plant productivity in acidic soils. Present work thereby analyzed Al-induced genomic alterations in Bryophyllum daigremontianum clones using RAPD and ISSR markers, and investigated responding changes in photosynthetic pigment (chlorophyll a, b, a/b, total chlorophyll and carotenoid) contents and total soluble protein amounts in plant leaves. The main reason for the use of bulbiferous spurs originated clone plants was to increase reliability and acceptability of RAPD and ISSR techniques in DNA fingerprinting. Raised 40 clone ...Более

Exact estimates for Faber polynomials and for norm of Faber operator

Fahreddin ABDULLAYEV

Exact estimates for Faber polynomials, norm of Faber operator, and -norm of the generating function for the sequence of Faber operator of univalent functions of class sigma are found. The description of continua of the complex plane for which the norm of Faber operator take the value 1 or 3 is obtained.

Two-dimensional parabolic problem with a rapidly oscillating free term

Ella ABILAYEVA | Asan ÖMÜRALİEV

The aim of this paper is to construct regularized asymptotics of the solution of a two-dimensional partial differential equation of parabolic type with a small parameter for all spatial derivatives and a rapidly oscillating free term. The case when the first derivative of the phase of the free term at the initial point vanishes is considered. The two-dimensionality of the equation leads to the emergence of a two-dimensional boundary layer. The presence in the free term of a rapidly oscillating factor leads to the inclusion in the asymptotic of the boundary layer with a rapidly oscillating na ...Более
