Investigation of heavy metals in tissues and habitats of three edible frogs from Turkiye
(Springer Link, 2024)The soil, water, and organisms have been contaminated by heavy metals due to human activities and industrialization, which has produced a major environmental problem that has a deleterious effect on human health and food ... -
Binding energies of shallow donors in polar ZnO/ZnBeO quantum well
(Elsevier, 2024)This study examines a single wurtzite ZnO/ZnBeO quantum well structure oriented in the polar c -direction. The focus is on investigating the binding energies associated with an impurity donor atom within this system. To ... -
Theoretical determination of electronic, geometric and spectroscopic properties of some 1,2,4-triazol derivatives
(2023)In this study, molecular geometric optimization of five 4,5-dihydro-1H-1,2,4-triazol-5-one derivative compounds was obtained using Density Functional Theory, (DFT, B3LYP)/ Hartree Fock, (HF, B3LYP) methods on the basis set ... -
Congruence relations and direct decomposition of uninorms on bounded lattices
(World Scientific, 2023)In this paper, the concept of U-compatible congruence and its related properties are studied. We also focus on homomorphism theorems for uninorms. Decomposition of uninorms is investigated via factor congruences, at first. ... -
Cellulose ester-based aerogel: lightweight and highly water-absorbent
(American Chemical Society, 2023)Cellulose was extracted from waste generated by pruning tea stem wastes. The interaction between pure cellulose and homophthalic acid produced a light (0.22 g·cm-3) and eco-friendly hybrid aerogel product that is highly ... -
Determination of bioremediation potentials and plant growth-promoting properties of bacillus species isolated from the rhizosphere of dactylorhiza urvilleana
(Namik Kemal University - Agricultural Faculty, 2023)Industrial activities have been one of the biggest factors of environmental destruction by affecting natural resources for decades. Heavy metals, which are one of the greatest dangers especially for the biosphere, can be ... -
Comparison of the Marsh Frog (Pelophylax ridibundus) populations living in different altitudes in terms of age, size, and some growth parameters
(Springer, 2024)Abstract: Ectothermic animals like amphibians have unique life histories that are impacted by a variety of eco-geographical variables. In this study, the impacts of altitude, which is one of the most frequently used ... -
The easternmost record of the Anatolian banded newt: The distribution of ommatotriton nesterovi (Caudata: Salamandridae) expands eastward in Türkiye
(Springer Link, 2024)Abstract: The Anatolian banded newt is an endemic amphibian species to the western and northern parts of Türkiye. The present study provides the new locality records of Ommatotriton nesterovi, which constitutes the species’ ... -
Tragopogon davutii-turanii: a new species of Tragopogon from Anatolia
(Wiley, 2024)A new salsify species, Tragopogon davutii-turanii, is described from Anatolia based on micro-/macro-morphological and molecular evidence. The new species is morphologically similar to T. vvedenskyi and T. abbreviatus, but ... -
