Carbon Nanotube Supported CdM(S, Se)/CdTe Anode Catalysts for Electrooxidation of Glucose in Alkaline Media

Hilal DEMİR KIVRAK | Nahit AKTAŞ

The sequential sodium borohydride (SBH, NaBH4) reduction method was utilized to prepare the 0.1 CdSe/CNT, 0.1 CdS/CNT, 0.1 (CdS-CNT)/CdTe, and 0.1 (CdSe-CNT)/CdTe catalysts. The XRD, SEM-EDS, TEM, and XPS analyses were used to characterize the catalysts. The electrochemical measurements were examined by cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) analyses for glucose electrooxidation. The characterization analyses revealed that the desired structure was formed on the support material. The electrochemical analysis results indicated that the ...Daha fazlası

The effects of novel electrical teat dipping on some mastitis parameters in dairy herds

Ali RIŞVANLI

Electrical teat dipping (ETD) is a novel, patented method developed by the authors to control mastitis in dairy cows. Here we evaluate the efficacy of ETD in reducing the incidence of clinical mastitis and bulk tank milk somatic cell count (BTMSCC) on three dairy farms over 6 months. ETD was applied for morning and evening milking on three farms, while conventional teat dipping (CTD) was applied on the other three farms. The number of animals and quarters with clinical mastitis and monthly BTMSCC measurements were recorded. We found that the incidence of clinical mastitis was lower on farms us ...Daha fazlası

Estimated Prevalence of Tuberculosis in Ruminants from Slaughterhouses in Constantine Province (Northeastern Algeria): A 10-Year Retrospective Survey (2011-2020)

Ulaş ACARÖZ

Tuberculosis (TB) is considered one of the most widespread and devastating zoonotic diseases in low-income countries, with a cosmopolitan distribution. The aim of this 10-year retrospective survey (from 2011 to 2020) was to determine the frequency of bovine, ovine, and goat tuberculosis in different local slaughterhouses across Constantine Province, Algeria. The control of livestock carcasses was systematically performed by veterinarian inspectors, after each stage of the slaughter process. The routine abattoir inspection included the detection of visible abnormalities on different organs and ...Daha fazlası

The relationship between Th1/Th2 cytokine polarization and milk composition in the postnatal period in Kyrgyz mares and foals

Fatih Ramazan İSTANBULLUGİL | Ali RIŞVANLI | Ruslan SALIKOV | Nariste KADIRALİYEVA | Ayday CUNUŞOVA

Immune compatibility between mare and foal is one of the important topics of reproductive immunology. At this point, although there are many studies on antibodies, there are not many publications on the relationship between the cytokine levels of mare, foal and milk and the effects of milk composition on this relationship. Here we investigate the relationship between Th1/Th2 cytokine balance and milk composition in Kyrgyz mares and foals. Samples were taken soon after the foal was born and on days 5, 10 and 20 after birth. Th1 (IFN-γ, IL-2, TNF-α) and Th2 (IL-4, IL-5, IL-10) cytokine levels in ...Daha fazlası

How social media affecting the mental health of Gen-Z: A mixed method study

The goal of this study was to examine how social media affecting the mental health of Gen-Z. This study uses a systematic search method to identify the effects of social media on mental health. We use previous research articles for this study, the relevant effect of social media on mental health has been discussed and highlights how excessive use of social media is damaging our generation. Social media like Facebook, twitter, Instagram, YouTube etc. were considered for this study. From the studies and analysis, we find that the use of social media has the following effect on mental health on t ...Daha fazlası

The Consecutive Substitution Method for Boundary Value Problems (BVPs) with Retarded Argument

Ercan ÇELİK

In this study, we applied an approximate solution method for solving the boundary value problems (BVPs) with retarded argument. The method is the consecutive substitution method. The consecutive substitution method was applied and an approximate solution was obtained. The numerical solution and the analytical solution are compared in the table. The solutions were found to be compatible. Keywords: approximate solution; boundary-value problem; numerical solution; retarded argument; solution methods; substitution method; boundary value problems

The power of retrotransposons in high-throughput genotyping and sequencing

Yılmaz KAYA

The use of molecular markers has become an essential part of molecular genetics through their application in numerous fields, which includes identification of genes associated with targeted traits, operation of backcrossing programs, modern plant breeding, genetic characterization, and marker-assisted selection. Transposable elements are a core component of all eukaryotic genomes, making them suitable as molecular markers. Most of the large plant genomes consist primarily of transposable elements; variations in their abundance contribute to most of the variation in genome size. Retrotransposon ...Daha fazlası

Fabrication of molecularly imprinted cotton fibers for quantification of streptomycin in honey samples

Nahit AKTAŞ

Streptomycin is a type of aminoglycoside used in treatment of several infections and with serious side effects in humans and animals, such as ototoxicity and nephrotoxicity. In the present study, we focused on the preparation of streptomycin-imprinted cotton fiber for rapid, sensitive and selective quantification of streptomycin in honey samples. The imprinted cotton fibers were characterized by attenuated total reflectance-Fourier transform spectroscopy, scanning electron microscopy, and x-ray photoelectron spectroscopy. In addition, the imprinted cotton fibers showed high adsorption capacity ...Daha fazlası

Impact of Subclinical Mastitis-causing Bacterial Species on the Composition and Chemical Properties of Milk

Ali RIŞVANLI

Background: Here we investigate whether the composition and some chemical properties of milk can correlate with bacterial species causing subclinical mastitis in cows.Methods: One hundred and eighty cows were used in the study. The California Mastitis Test (CMT) was applied to the selected cows. The cows were divided into four groups: cows with negative CMT (n45), the Escherichia coli (n45), Streptococcus agalactiae (n45) and Staphylococcus aureus (n45) groups.Result: Milk composition and some chemical properties were measured. The highest fat ratio (5.82 /- 0.34) was found in the Escherichia ...Daha fazlası
