Predicting the success of an invader: Niche shift versus niche conservatism
(Wiley, 2019)Invasive species can encounter environments different from their source populations, which may trigger rapid adaptive changes after introduction (niche shift hypothesis). To test this hypothesis, we investigated whether ... -
Preliminary data on the age structure of Asaccus barani (Baran's leaf-toed gecko) from southeastern Anatolia, Turkey
(2015)In this study, the age structure of an Asaccus barani sample from Şanlıurfa (southeastern Anatolia, Turkey) was determined by skeletochronology for the first time. A total of 17 preserved adults (7♂♂, ... -
Preparation and antimicrobial activity evaluation of some new bi- and triheterocyclic azoles
(Springer Birkhauser, 2013)Synthesis of the carbothioamides (5, 13, 22) was performed starting from 3H-1,2,4-triazol-3-ones (2, 17) by several steps, and then, these carbothioamides was converted to triheterocyclic compounds incorporating 1,2,4-triazole, ... -
Preparation and antimicrobial activity evaluation of some quinoline derivatives containing an azole nucleus
(2012)Quinoline-2-carbohydrazide (2) obtained from quinaldic acid (1) was converted to the corresponding carbothioamide 3 and carboxamide 6 by treatment with benzyliso(thio)cyanate. The basic treatment of 3 and 6 yielded the ... -
Preparation and characterization of "green" hybrid clay-dye nanopigments
(Pergamon-Elsevier Science Ltd, 2015)We obtained a low cost and abundant nanopigment material composed of Rhodamine B (Rh-B) organic dye compound and Unye bentonite (UB) clay from Turkey. the characterization of the nanopigment was investigated using scanning ... -
Preparation and characterization of a novel activated carbon component via chemical activation of tea woody stem
(Springer, 2019)The novel activated carbon materials were synthesized by the carbonization and chemical activation of agricultural bio-waste from tea woody stems (TWS), and these materials were characterized by using FTIR, SEM, TG/DTA and ... -
Preparation and characterization of new window material CdS thin films at low substrate temperature (<300 K) with vacuum deposition
(Elsevier, 2011)Low-temperature vacuum deposition instead of the commonly used vacuum deposition at high substrate temperatures has been applied to prepare new window material CdS thin films. The structural, optical and electrical properties ... -
Preparation and characterization of the highly efficient tetraphenylimidazole substituted Phthalocyanine/ZnO composite and investigation of its effect on the photocatalytic degradation of Rhodamine B and 2,4,6-trichlorophenol
(Elsevier, 2024)Growing concerns about industrial waste-induced environmental degradation have driven research towards sustainable solutions. Photocatalytic degradation, fueled by light and avoiding harmful chemicals, offers a promising ... -
Pretreatment with polyamines alleviate the deleterious effects of diuron in maize leaves
(Akademiai Kiado Rt, 2015)The effects of diuron, a photosystem II inhibiting herbicide, on lipid peroxidation, photosynthetic pigments, soluble protein, proline contents and some antioxidant enzymes in maize leaves were studied and protective effects ... -
Prevalence and phylogenetic analysis of Ascosphaera apis (Maassen ex Claussen) LS Olive & Spiltoir (1955) isolates from honeybee colonies in Turkey
(Springer, 2022)Ascosphaera apis (Maassen ex Claussen) Olive et Spiltoir is a causal agent of chalkbrood disease and is widely found in mainly honeybee colonies worldwide. Chalkbrood disease rarely causes colony death, but severe infections ... -
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 ... -
