Genetic data to describe the hybrid zone between Bufo bufo (Linnaeus, 1758) and Bufo verrucosissimus (Pallas, 1814) in northeastern Türkiye
(Brill Academic Publishers, 2023)Hybrid zones are geographic areas where individuals from distinct taxa meet, mate, and hybridize. These zones may have complex histories, but many of them originated relatively recently, during climatic oscillations in the ... -
One-neutron transfer reaction in the O 18 + Ti 48 collision at 275 MeV
(American Physical Society, 2023)The present article reports new data on the 48 Ti ( 18 O , 17 O ) 49 Ti reaction at 275 MeV incident energy as part of the systematic research pursued within the NUMEN (NUclear Matrix Elements for Neutrinoless ... -
Changing the conductivity type of ultrasonically sprayed ZnO thin films: comparison of the effects of Li, N, and B dopants
(Springer, 2023)ZnO is a material widely used in technological applications. However, the difficulty of preparing p-type ZnO creates a bottleneck for developing ZnO-based devices. In this study, Li, N, and B-doped ZnO thin films were ... -
Indole-pyridine carbonitriles: multicomponent reaction synthesis and bio-evaluation as potential hits against diabetes mellitus
(2023)Background: Diabetes mellitus is a significant health disorder; therefore, researchers should focus on discovering new drug candidates. Methods: A series of indole-pyridine carbonitrile derivatives, 1-34, was synthesized ... -
Effect of precursor solution molarity on electrical and optical properties of spin-coated titanium dioxide (TiO2) thin films
(Springer, 2023)In our study, we investigated the electrical and optical properties of TiO2 thin films deposited on p-type c-Si using the spin coating method at different molarities. We observed that as molarity increased, reflectance ... -
Comparative phytochemical and bioactivity studies on two related Scorzonera L. species: A chemotaxonomic contribution
(Elsevier, 2023)Scorzonera L. (Asteraceae) is considered a taxonomically difficult genus with its more than 160 species. Scorzonera bella (SB) and S. veratrifolia (SV) species have been treated as synonyms since 1975. Recent botanical ... -
Determination of biocontrol properties of two local trichoderma isolates
(Springer, 2023)Many plant pathogens, especially Rhizoctonia solani, Pythium spp. and Alternaria spp. can seriously affect seedling growth and crop production. Trichoderma is recognized as a suitable biological plant protection product ... -
Moment-based approximations for stochastic control model of type (s, S)
(Taylor & Francis Ltd., 2023)In this study, we propose an approximation for a renewal reward process that describes a stochastic control model of type (s, S) based on the first three moments of demand random variables. Various asymptotic expansions ... -
On the eigenstructure of the q -Durrmeyer operators
(TUBITAK, 2023)The purpose of this paper is to establish the eigenvalues and the eigenfunctions of both the q -Durrmeyer operators Dn,q and the limit q -Durrmeyer operators D∞,q introduced by V. Gupta in the case 0 < q < 1. All moments ... -
Modeling disease transmission dynamics with random data and heavy tailed random effects: Rhe zika case
(Isik University, 2023)In this study, we investigate a compartmental model of Zika Virus transmission under random effects. Random effects enable the analysis of random numerical characteristics of transmission, which cannot be modeled through ... -
Determination of the chemical composition in different plant parts of S. Mollis taxa
(Babes-Bolyai University, 2023)The volatile oil composition and secondary metabolite content in different parts of S. mollis ssp. mollis and S. mollis ssp. szowitzii were investigated in this study. Based on their chemical composition, the components ... -
Growth and characterization of CT(S,Se) thin films and Al/n-Si/p-CT(S,Se)/Mo heterojunction diode application employing a two-stage process
(Elsevier, 2023)Cu2SnS3 (CTS), Cu2Sn(S,Se)3 (CTSSe), and Cu2SnSe3 (CTSe) thin films were deposited on n-type silicon wafer substrates using a two-stage process. This process involved drop-coating Cu-Sn precursors, which is different from ... -
Stereo- and Regio-selective benzo- and Benzohalo-conduritols: Anti-diabetes & anti-tumor activity investigation, kinetic and molecular docking studies
(Elsevier, 2023)In this study, benzoconduritols, benzohalogenoconduritol, and benzodihalogenoconduritols with conduritol-A and –C structures from oxo-norbornene derivative endo-10 b, exo-11 b cleavaged by Lewis acids (BBr3, BCl3, BF3· ... -
Hyper dual number matrices
(Maejo University, 2023)We study hyper dual numbers and hyper dual number matrices. Firstly, we give some basic properties of dual numbers and hyper dual numbers. Next, we investigate hyper dual number matrices using the properties of dual number ... -
A comprehensive study on a medicinal and edible plant scorzonera incisa DC., discussing the natural limits of phytochemical profiling
(Wiley, 2023)Leaves of Scorzonera incisa DC. (Asteraceae) are eaten raw against diabetes and headache. Evaluation of medicinal, edible plants using profiling methods has become a common phenomenon. Petroleum ether (PE), ethyl acetate ... -
Dynamics of a plant-herbivore model subject to allee effects with logistic growth of plant biomass
(World Stientific Publishing, 2023)This paper examines the relationship between herbivores and plants with a strong Allee effect. When the plant reaches a particular size, the herbivore attacks it. We use the logistic equation to model plant growth and ... -
Non-native and native tree species plantations and seasonality could have substantial impacts on the diversity of indigenous soil fauna in a semi-arid forest ecosystem
(Springer, 2023)The temporal and spatial dynamics of soil fauna in many terrestrial ecosystems are still not fully understood, while soil fauna is one of the most critical characteristics in assessing soil quality. Therefore, the efects ... -
