Occurrence of microplastics in herpetological museum collection: Grass snake (Natrix natrix [Linnaeus, 1758]) and dice anake (Natrix tessellata [Laurenti, 1769]) as model organisms
(Springer, 2022)Microplastics are plastic fragments with a size less than 5 mm in length. In addition to a threat to the marine environments where these are abundantly present, these have also started polluting freshwater ecosystems. ... -
Demographic life-history traits in two populations of Cyrtopodion scabrum (Squamata: Gekkonidae)
(Society Brasileria Herpetologia, 2022)In the present study, some demographic life-history parameters (e.g., age structure, age upon attaining sexual maturity, longevity, adult life expectancy, growth, and survival rate) and body size were investigated for the ... -
Morphological variability and age structure in a population of Bufo verrucosissimus (Anura: Bufonidae) from Artvin, Turkey
(University Sao Esalo, 2022)Morphological variability and age structure in a population of Bufo verrucosissimus (Anura: Bufonidae) from Artvin, Turkey. We investigated morphological diversity (external body traits, coloration patterns and skin ... -
Evaluation of the chemical composition in different plant parts of Scorzonera Papposa
(Parlar Scientific Publications, 2022)Scorzonera papposa, a member of the Scorzonera genus, is not investigated deeply regarding its volatile oil composition and seconder metabolite content in Turkey. In our study we were able to distinguish Scorzonera papposa ... -
Catalytic activity of palladium doped activated carbon from waste coffee on some environmental pollutants
(Elsevier, 2022)The presence of nitro compounds and such commercial dyes as Congo red, methylene blue, methyl orange and methyl red in water/wastewater causes environmental issues. The treatment of such industrial contaminants, new efficient ... -
The study of superconducting and magnetic properties of bis oxalate (C22H22O6) added bulk MgB2
(Elsevier, 2022)The effect of bis oxalate (C22H22O6) addition on critical current density (J(c)), lattice parameters, microstructure, superconducting temperature (T-c), magnetic levitation force (F-z) and lateral force (F-x) properties ... -
Compactness of quadruple band matrix operator and geometric properties
(Sciendo, 2022)In this work, we characterize the class of compact matrix operators from c(0)(Q), c(Q) and l(infinity)(Q) into c(0), c and l(infinity), respectively, with the notion of the Hausdorff measure of noncompactness. Moreover, ... -
Isolation, characterization, and comparative genomic analysis of vB_PlaM_Pd22F, a new bacteriophage of the family Myoviridae
(Springer, 2022)The use of phage and phage-based products for the prevention and treatment of bee disease is one of the promising natural alternatives to chemical or antibiotic treatments in beekeeping. A novel lysogenic bacteriophage, ... -
Inhibition and purification of acetylcholinesterases from adults and nymphs of Ricania simulans (Walker, 1851) (Hemiptera: Ricaniidae)
(Springer, 2022)Ricania simulans (Walker, 1851) (Hemiptera: Ricaniidae) has been causing damage in agricultural areas along the eastern Black Sea coastline since 2006. As there are not enough studies on managing this pest, it continues ... -
Investigation and mapping of natural and artificial radioactivity in sediment samples from Borcka Black Lake, Artvin-Turkey
(Taylor & Francis Ltd., 2022)All living creatures in nature are constantly exposed to ionising radiation, which is emitted from natural and artificial radiation sources. For this reason, it is important to monitor the levels of radioactivity in living ... -
Monitoring and distribution of kdr and ace-1 mutation variations in Culex pipiens L., 1758 (Diptera: Culicidae) in artificial sites and agricultural fields in the central and eastern Black Sea Region of Türkiye
(Türkiye Entomoloji Derneği, 2022)Culex pipiens L., 1758 (Diptera: Culicidae) is one of the most important pests and disease vectors in the world. It is of major importance to monitor the development of insecticide resistance in order to effectively control. ... -
Synthesis of quinazolinone derivatives containing an acyl hydrazone skeleton as potent anti-urease agents enzyme kinetic studies and anti-oxidant properties
(Sage Publications, 2022)This paper covers the synthesis, in vitro urease inhibition, enzyme kinetic parameters, and anti-oxidant studies of a novel series of quinazolinone derivatives containing an acyl hydrazone skeleton. Compounds 3a, 3b, 5a, ... -
Generalized osculating curves of type (n-3) in the n-dimensional Euclidean space
(Ankara University, 2022)In this paper, we give a generalization of the osculating curves to the n-dimensional Euclidean space. Based on the definition of an osculating curve in the 3 and 4 dimensional Euclidean spaces, a new type of osculating ... -
Trace element bioaccumulation and health risk assessment derived from leg consumption of the marsh frog, Pelophylax ridibundus (Pallas, 1771)
(Ege University, 2022)Amphibians, which can live in aquatic and terrestrial environments, are a good indicator of pollution in these areas. Although frog leg is not consumed frequently in some cuisines, including Turkey, it is important in terms ... -

Some notes on crossed semimodules
(Scientific Technical Research Council Turkey, TÜBİTAK, 2022)In this paper, we introduce the notion of lifting via a homomorphism of monoids for a crossed semimodule and give some properties. Further, we characterize actions and coverings of Schreier internal categories in the ... -
Explicit formulas for exponential of 2×2 split-complex matrices
(Ankara University, 2022)Split-complex (hyperbolic) numbers are ordered pairs of real numbers, written in the form x + jy with j(2) - 1, used to describe the geometry of the Lorentzian plane. Since a null split-complex number does not have an ... -
