Prevalence of integrons and a new dfrA17 variant in Gram-negative bacilli which cause community-acquired infections
(Wiley, 2010)A hundred and eleven Gram-negative bacilli from community-acquired infections were characterized by antimicrobial susceptibility testing, screened for class 1 and 2 integrons, and statistically evaluated for the association ... -
Prevalence of microplastics in commercially sold soft drinks and human risk assessment
(Elsevier, 2023)Due to the increasing global plastic production and use in recent years, the amount of microplastic (MP) accumulating in the environment has also increased. This microplastic pollution potential has been documented mostly ... -
Processing CdS- and CdSe-containing window layers for CdTe solar cells
(Elsevier, 2021)The influence of heat treatment steps on the characteristics of (CdS, CdSe) junction partners and on solar cell performance was studied. CdS films were obtained by chemical bath deposition, and CdSe layers were evaporated. ... -
Production and characterization of activated carbon foams with various activation agents for electrochemical double layer capacitors (EDLCs) applications
(Elsevier, 2024)Sucrose-based activated carbons were obtained by carbon foams with sugar and cobalt (II) nitrate as precursors, followed by using different chemical activation agents. The effect of Co(NO3)2 concentration, the carbonization ... -
Protective effect of a natural ally on simultaneous mild heat and salt episodes in maize seedlings
(Springer Heidelberg, 2018)Abiotic stresses occur together in several combinations in nature and do not usually act alone. However, studies on plants mainly are limited to a single stress type. Yet, atmospheric trends make it indispensable to expand ... -
Pseudomonas putida KT2440 induces drought tolerance during fruit ripening in tomato
(University Centroccidential Lisandro Alvarado, 2022)The current study investigated the effects of Pseudomonas putida strain KT2440 on the drought tolerance of tomato plants during fruit maturation. Plants at the ripening stage of the mature-green were not watered for 20 ... -
A psychometric scale for determining university students' attitudes towards the statistics courses they take: Statistical attitude scale (SAS)
(2014)The aim of this study is to develop a Likert type scale to measure the attitudes of university students towards the statistics course they take. Firstly, first and third grade students from Ondokuz Mayis University Arts ... -
Purification and characterisation of a polyphenol oxidase from Boletus erythropus and investigation of its catalytic efficiency in selected organic solvents
(Elsevier, 2010)Polyphenol oxidase (PPO) was purified from Boletus erythropus using a Sepharose 4B-L-tyrosine-p-amino benzoic acid affinity column. Optimum pH and temperature were found to be 8.0 and 20 °C, respectively, using 4-methylcatechol ... -
Purification and characterization of a polyphenol oxidase from cimin grape (Vitis vinifera spp., Cimin)
(Research Journal Biotechnology, 2016)A polyphenol oxidase (PPO) from Cimin grape was purified 11.2-fold by using a Sepharose 4B-L-tyrosine-p-aminobenzoic acid affinity column. the optimum pH and temperature of PPO purified from Cimin grape were 7.5 and 30 ... -
Purification and characterization of an extracellular lipase from Mucor hiemalis f. corticola isolated from soil
(Elsevier, 2012)We have screened 39 microfungi isolates originated from soil in terms of lipolytic activity. Out of all screened, a novel strain of Mucor hiemalis f. corticola was determined to have the highest lipase activity. The ... -
