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 ... -
O 18 + Ti 48 elastic and inelastic scattering at 275 MeV
(American Physical Society, 2024)Background: In recent years, the NUMEN project has highlighted that the systematic study of double charge exchange (DCE) nuclear reactions could provide precious information on the nuclear matrix elements of neutrinoless ... -
Impact of CdSeTe and CdSe film deposition parameter on the properties of CdSeTe/CdTe absorber structure for solar cell applications
(Institute of Physics, 2024)In this study, the effect of depositing CdSeTe and CdTe layers at different substrate temperatures (STs) by evaporation in vacuum on the properties of the CdSeTe/CdTe stacks was investigated. First, CdSeTe layers in stack ... -
Human health risk assessment of heavy metals accumulation in different genders and tissues of whiting fish (Merlangius merlangus euxinus Nordmann, 1840) from Rize, Turkey
(Elsevier, 2024)The contamination of fish resulting from marine pollution is a major concern, as it poses potential adverse effects on human health. Therefore, heavy metal concentrations (Cr, Fe, Ni, Cu, Zn, and Pb) in different genders ... -
