Surgical removal of Coenurus cerebralis cysts located in the brain of sheep

Abuzer TAŞ | İsmail ŞEN | Fatih HATİPOĞLU | Hasan Hüseyin ARI | Ruslan SALIKOV | Nur ABDIMANAP UULU | Ayperi Aytmırza Kızı

Coenurosis caused by Coenurus cerebralis poses a significant economic threat to sheep. To date, no effective treatment has been identified for this parasitic infection once it has settled in the brain. This study aimed to investigate the surgical removal of C. cerebralis cysts from the brains of infected sheep. Twenty sheep were utilized in the experiment, and the animals underwent a 24-hour fasting period before the surgical procedure. Various biochemical parameters, including TP, ALP, BUN, AST, CK, LDH, RBC, WBC, Hb, and Hct, were measured in the animals both before and one month after the o ...More

Effect of Impact Angle and Speed, and Weight Abrasive Concentration on AISI 1015 and 304 Steel Exposed to Erosive Wear

Refik POLAT

This study investigated parametrically the erosive wear behavior of AISI 1015 and 304 steel in different environmental conditions. The erosive wear tests were designed according to the L9 orthogonal array design of the Taguchi fractional factorial method. The experiments were carried out with the parameters of 3-level slurry concentration formed with silica powder (5, 15, and 25 wt.), 3-level impact velocity (265, 397.5, and 530 rpm), and 3-level impact angle (30°, 60°, and 90°). Surface roughness and weight loss were considered performance criteria in the experimental data assessed using the ...More

Selective Electrochemical Determination of L-Cysteine by a Cobalt Carbon Nanotube (CNT)-Modified Glassy Carbon Electrode (GCE)

Nahit AKTAŞ

L-Cysteine is a semi-essential and proteinogenic amino acid, with the formula HO2CCH (NH2) CH2SH. L-cysteine is mostly found in protein-rich foods. In this study, catalysts consisting of cobalt (Co) supported on carbon nanotubes (CNTs) were prepared using the sodium borohydride (NaBH4) reduction method. These catalysts were characterized by means of energy-dispersive x-ray (EDX) with scanning electron microscopy (SEM), temperature-programmed reduction (TPR), and temperature-programmed oxidation (TPO) techniques. Characterization results confirmed the successful preparation of the desired catal ...More

Human Exposure to Naturally Occurring Bacillus anthracis in the Kars Region of Eastern Türkiye

Mitat ŞAHİN

Environmental contamination with Bacillus anthracis spores poses uncertain threats to human health. We undertook a study to determine whether inhabitants of the anthrax-endemic region of Kars in eastern Türkiye could develop immune responses to anthrax toxins without recognised clinical infection. We measured anti-PA and anti-LF IgG antibody concentrations by ELISA in serum from 279 volunteers, 105 of whom had previously diagnosed anthrax infection (100 cutaneous, 5 gastrointestinal). Of the 174 without history of infection, 72 had prior contact with anthrax-contaminated material. Individuals ...More

Influence of boundary conditions on the behavior of laminated glass curved beam with delamination effect: An experimental and numerical investigation

Ebru DURAL

The delamination phenomena of laminated glass structures are issues that are not perfectly understood and remain problematic to predict due to the nonlinearity of the geometric response. A research study is undertaken to investigate the behavior of laminated glass curved beams with initial delamination exposed to different boundary conditions. A mathematical model which contains nonlinear field equations and boundary conditions is developed. An iterative procedure for the solution of field equations is implemented. In addition, experiments are conducted and finite element model is developed to ...More

Renewable-based treatment solution of Reactive Blue 21 dye on fly ash as low-cost and sustainable adsorbent

Mehmet KOBYA

This study investigated the removal of Reactive Blue 21 (RB 21) dye from aqueous solutions by adsorption, evaluating the waste fly ash (FA). The effects of the parameters, such as initial dye concentration (100–750 mg/L), initial pH (2.0–8.0), adsorbent dose (1.0–4.0 g/L), and temperature (298–323 K) on the adsorption process were investigated. The optimum initial pH value was 2.0 for the highest RB21 dye removal (75.2 mg/g). At optimized conditions (pH 2.0, an adsorbent dosage of 1.0 g/L, a dye concentration of 750 mg/L, and an equilibrium time of 72 h), the highest adsorption capacity was fo ...More

Exploring the impact of university support on students' entrepreneurial intentions: evidence from Kyrgyzstan

Azamat MAKSUDUNOV

Whether university support is meaningful in increasing students' entrepreneurial intentions (EI) remains largely under-investigated, especially in the context of Central Asian countries. In this study, we attempted to address this question by examining the effects of university support (comprised of educational support, concept development support, and business development support) on students' EI. We employed a structured questionnaire to collect data from 793 student respondents enrolled in 13 universities in Kyrgyzstan and performed descriptive and inferential statistical analyses. Our anal ...More

The Role of Bee Products in the Control of Antimicrobial Resistance and Biofilm Formation

Ulaş ACARÖZ | Fatih Ramazan İSTANBULLUGİL | Damla ARSLAN ACARÖZ

The discovery of antibiotics saved many lives. Infections were not as deadly a problem for clinicians as they once were. However, due to inappropriate and excessive use of antibiotics, antibiotic resistance has increased dramatically worldwide. Infectious diseases are becoming more challenging to control, and they cause increased morbidity and mortality. Also, a significant risk to human health is posed by infections associated with biofilms. To combat these drug-resistant microorganisms, several novel and alternative strategies have been identified. Bee products such as honey, bee pollen, pro ...More

A 2,2-dichloropropionic acid-degrading novel Pseudomonas fluorescence strain fatsa001: isolation, identification, and characterization

Gülbübü KURMANBEKOVA | Yılmaz KAYA

There are mounting concerns over the high concentrations of non-biogenic, toxic halogenated organic compounds being liberated into the ecosystem. Therefore, this study’s isolation of a novel bacterium from a contaminated stream in Fatsa, Ordu, Turkey, adept in degrading 2,2-dichloropropionic (of 2,2-DCP) is a welcome endeavor. The ability of the bacterial isolate to utilize 2,2-DCP as the sole carbon and energy source was discovered when the bacterium was observed to grow well on liquid minimal media containing 20 mM of 2,2-DCP, showing a doubling time of 14.2 h. The following genetic and bioc ...More

On the Solvability of a Boundary Value Problem for Nonlinear Optimization of Oscillatory Processes

Elmira ABDILDAYEVA

The paper investigates the solvability of a boundary value problem in the control of an oscillatory process described by control in partial derivatives of the first order. It has been established that there are an infinite set of controls, as solutions to the system of nonlinear Fredholm integral equations of the first kind, each of which transfers the controlled process from the initial state to the final specified state in a specified time. Sufficient conditions for the existence of a nonlinear optimization solution are found.
