Exploration of seasonal metal pollution in Karacaören II Dam Lake sediment samples using X-ray Fluorescence method
(Sivas Cumhuriyet Üniversitesi, 2023)In this study, the seasonal metal pollution of sediment samples taken from twelve distinct notes of the Karacaören II Dam Lake was examined. The quantity of metal in soil samples was determined using energy dispersive ... -
Exploring codon usage patterns and influencing factors in ranavirus DNA polymerase genes
(Wiley, 2024)Ranaviruses, members of the genus Ranavirus within the family Iridoviridae, have become a significant concern for amphibian populations globally, along with other cold-blooded vertebrates, due to their emergence as a ... -
Expression in poplar of dehydroshikimate dehydratase induces transcriptional and metabolic changes in the phenylpropanoid pathway
(Oxford Academic, 2024)Modification of lignin in feedstocks via genetic engineering aims to reduce biomass recalcitrance to facilitate efficient conversion processes. These improvements can be achieved by expressing exogenous enzymes that interfere ... -
An extended model for coexistence of superconductivity and paramagnetism in high-Tc superconductors
(2008)In the present work, the total magnetization in superconducting state is separated into critical state and paramagnetic components in terms of an H(x)-dependent magnetic flux density. Utilizing this model, we reproduce ... -
An extension method for t-norms on subintervals to t-norms on bounded lattices
(Kybernetika, 2019)In this paper, a construction method on a bounded lattice obtained from a given t-norm on a subinterval of the bounded lattice is presented. the supremum distributivity of the constructed t-norm by the mentioned method is ... -
Extension of TODIM method based on distance measures of decomposed fuzzy sets
(Springer, 2024)Fuzzy sets allow elements to have partial membership in a set, represented by a membership value between 0 and 1. This feature enables fuzzy sets to model imprecise or vague concepts. Decomposed fuzzy sets, an extension ... -
Fabrication and characterization of Au/n-ZnO/p-Si/Al sandwich device with Sol-gel spin coating method
(Springer, 2019)ZnO thin films with the n-type properties were obtained on the p-Si substrates for multi-layered sandwich device depositing by sol-gel method. Au and Al were conducted on two side of hetero-junction by PVD technique. From ... -
Fabrication of CdS nanospheres-based hybrid solar cells having increased efficiency
(Springer, 2022)The impact of surface modification through diverse dyes (Eosin-Y, D205, N719 and N3) on structural, morphological, optical, and electrical properties of CdS/P3HT hybrid solar cells is studied. X-ray diffraction (XRD) pattern ... -
Fabrication of gold thin films on cooled glass substrates
(Springer, 2024)In this article, gold (Au) thin films were fabricated on glass substrates under vacuum conditions (4.5 x 10(-6) Torr) within a temperature range of 100-300 K, incrementing in steps of 50 K. Analyses through Field Emission ... -
A facile and sensitive coprecipitation method coupled with flame atomic absorption spectrometry for quantification of Cu(II) ions in complex matrices
(Serbian Chemical Society, 2023)In the present investigation, the application of an organic coprecipitant, 2-[5,6-dichloro-2-(2-bromobenzyl)-1H-benzimidazole-1-yl]acetohydrazide (DIBBA), for separation and preconcentration of Cu(II) ions in fruit and ... -
Facile synthesis and characterization of CdS thin films doped by yttrium atoms
(Springer, 2023)A facile preparation and structural, optical and electrical characterization of undoped and Y-doped CdS thin films are demonstrated through spray pyrolysis changing doping concentration of yttrium atoms in CdS structure. ... -
A facile ultrasonic synthesis approach to 3-H-quinazolinethione derivatives and their urease inhibition studies
(Taylor & Francis Ltd., 2024)In this study, a new series of 3H-quinazoline-4-thione derivatives were synthesized under ultrasonic irradiation conditions with high yield in a short time. The new compounds were characterized by FT-IR,H-1, and C-13 NMR ... -
Family of surface with a common null geodesic
(2009)We analyzed the problem of finding a surfaces family through a null curve with Cartan frame. We constructed a differential equation system such that a given null curve is an isogeodesic curve on a surface. In addition, ... -

(Elsevier Science Bv, 2016)A new ferrocenyl-substituted heterocyclic hydrazide ligand and its Cu(II) complex were prepared. the DFT calculations were performed to determine the electronic and molecular structures of the title compounds. the electronic ... -
Fifty years of adventure: Relations between Turkey and Iceland
(Pamukkale Üniversitesi, 2021)This study deals with Turkey-Iceland relations between 1930 and 1980. Relations between these two countries, which have completely different cultures and geographies, have always been limited because they have a long-distance ... -
The fine spectral tuning of plasmon mode and quantum emitter coupling and its comparison with the dark-hot resonances
(Scientific Technical Research Council Turkey - TUBİTAK, 2022)Localization of incident fields into very small volumes (hot-spots) allows strong light-matter interactions at the hot spots. This makes path interference effects, Fano resonances, visible. Fano resonances can appear due ... -
Fine-tuning the element dose in nanoparticle synthesis is the critical factor determining nanoparticle's impact on plant growth
(Elsevier, 2024)This study elucidates the impact of element dose during nanoparticle (NPs) synthesis on plant growth indices. Novel NPs containing two essential micro-nutrients, zinc (Zn) and manganese (Mn), were co-doped on cerium oxide ... -
First data on DNA barcoding of the Agamidae (Reptilia: Squamata) from Anatolia, Turkey
