In this paper, solution of the following difference equation is examined
x(n+1) = x(n-13)/1+x(n-1)x(n-3)x(n-5)x(n-7)x(n-9)x(n-11),
where the initial conditions are positive real numbers.

In the recent years, there has been a lot of interest in studying the global behavior of, the socalled, max-type difference equations; see, for example, [1-17]. The study of max type difference equations has also attracted some attention recently. We study the behaviour of the solutions of the following system of difference equation with the max operator:paper deals with the behaviour of the solutions of the max type system of difference equations,
x(n+1) = max {A/x(n-1) , y(n)/x(n)}; y(n+1) = max {A/y(n-1) , x(n)/y(n)}, (1)
where the parametr A and initial conditions x(-1), x(0), y(-1), y(0 ...More
In this article the results of calculations of experimental-statistical methods are given, using the optimized contents of components in "Puff buns" and "Grain bars" recipes. The proposed products are balanced in the content of nutrients (proteins, fats, carbohydrates), contain a wide range of vitamins and essential amino acids, which allows expanding the consumer food market and more efficiently using vegetable resources. In order to obtain the percentage ratio of the components in the flour products composition, the complete factor experiment - a central compositional rotatable planning expe ...More

Mycoplasma haemocanis (Mhc) and Candidatus Mycoplasma haematoparvum (CMhp) have been investigated using species specific PCR and sequencing in 170 dogs from Kyrgyzstan. Maximum likelihood estimation (MLE) of the infection rates with 95% confidence intervals (CI) was calculated. The molecular prevalence of hemoplasma infection was 5.29% (CI 2.57-9.34). It was found that, five (2.94%, CI 1.06-6.22) samples were found to be infected with Mhc, one (0.59%, CI 0.03-2.57) sample with CMhp and three (1.76%, CI 0.44-4.52) samples with both species. These results demonstrate that dogs can be exposed to ...More
A novel molecularly imprinted polymer was synthesized on magnetic halloysite nanotube via surface initiated reversible addition-fragmentation chain transfer polymerization in the presence of 2-aminoethylmethacrylamide, 2-Cyano-2-propyl benzodithioate, ethylene glycol dimethacrylate (EGDMA) and azobis(isobutyronitrile) for sensitive and selective spectrophotometric determination of metoclopramide in urine samples. The synthesized imprinted polymer was characterized by several surface characterization techniques and the results indicated there was a thin polymer network on the magnetic halloysit ...More

BACKGROUND: Regular exercise activities affect blood cells. OBJECTIVE: The purpose of this study was to evaluate the seasonal evaluation of some hematological and biochemical parameters of the Olympic Greco-Roman wrestlers. METHODS: A total of 3 measurements were performed on wrestlers: immediately before the training period, three months and six months after the training session. Hematological and biochemical parameters were analyzed by taking sufficient blood samples from the athletes before and after exercise. RESULTS: The total leukocyte, lymphocyte, and neutrophil values were found to be ...More
Empati, başkalarının düşüncelerine ve duygularına ilişkin içgörüler elde etmek amacıyla; gözlem, hafıza, bilgi ve akıl yürütmenin birleştirildiği karmaşık bir psikolojik perspektif alma becerisidir. Kişinin yaptığı eylemlerin olumsuz sonuçlarını görebilmesi de büyük ölçüde empati becerisinin düzeyi ile ilgilidir. Bencillik; kişisel çıkarlarını korumak ve gözetmek ötesinde, bir başkasının zarar görmesi adına kişisel çıkar arayışıdır. Narsist kişiliğin en önemli göstergeleri ise kendisinin önemine dair büyüklenmeci bir duygu, hak sahibi olduğuna inanma kişilerarası ilişkilerde sömürücülük, amaçl ...More
This study was performed to evaluate the end systolic wall stress/end-systolic volume index ratio (ESWS/ESV-I) for LV systolic function in Anatolian shepherd dogs (ASHs) with stage B2 degenerative mitral valve disease (DMVD). Thirty-eight adult ASHs with DMVD (experimental group; 20 B1 dogs and 18 B2 dogs) and 30 weight-matched adult healthy ASHs (control group) were used as subjects. There was no overlap for the ESW5/ESV-I ratio (0.83 +/- 0.03, range: 0.61-1.09 for B2 dogs, 1.34 +/- 0.05, range: 1.11-1.89 for B1 dogs, 2.171 +/- 0.0 range: 1.91-3.02 for the control dogs) among the groups. ESWS ...More
In this study a novel and smart multi-functional hydrogel (MFH) was synthesized from N, N dimethyl acrylamide (DMAAm), gelatin, citric acid (CA) and pomegranate extract (PE) for instant and easy monitoring of the color change in MFH due to changes in medium conditions such as pH and temperature. MFH was utilized as food packaging material, equipped with the developed properties. MFH was synthesized with a redox polymerization technique in film form on petri dishes. Mechanical and water resistance properties of MFH were improved by CA and N, N, methylenebisacrylamide, while PE was used to gain ...More

The work is devoted to the construction of the asymptotics of the solution of a singularly perturbed system of equations of parabolic type, in the case when the limit equation has a regular singularity as the small parameter tends to zero. The asymptotics of the solution of such problems contains, along with parabolic boundary layer functions, and power boundary layer functions.
Developing gene transfer technologies enables the genetic manipulation of the living organisms more efficiently. The methods used for gene transfer fall into two main categories; natural and artificial transformation. The natural methods include the conjugation, transposition, bacterial transformation as well as phage and retroviral transductions, contain the physical methods whereas the artificial methods can physically alter and transfer genes from one to another organisms
Electrochemical and spectroelectrochemical properties of newly synthesized diazonium salt of 2-(2-(1,3-dioxo- 3,3a-dihydro-1H-isoindol-2(7aH)-yl)-1-(3 methyl-3-phenylcyclobutyl)ethylidene) hydrazinecarboxamide (DDPHC-DAS) were studied using glassy carbon (GC) electrode. In the current study, surface characterization was performed by cyclic voltammetry (CV). Besides electrochemical impedance spectroscopy (EIS) was used for the electrochemical and spectroelectrochemical characterization. Surface images were obtained using scanning electron microscopy (SEM). After completion of modification and c ...More
