Evaluation of the convolution sum ∑al+bm=nσ(l)σ3(m) for (a,b)=(1,7),(7,1),(1,8),(8,1),(1,9),(9,1) and representations by certain quadratic forms in twelve variables
(Springer, 2023)For a positive integer n we evaluate the convolution sum Sigma(al+ bm=n) sigma(l) sigma(3)(m) for (a, b) = (1, 7), (7, 1), (1, 8), (8, 1), (1, 9), (9, 1) . We then use these evaluations together with knownevaluations of ... -
On the injectivity with respect to q of the Lupaş q-transform
(Taylor & Francis Ltd., 2023)The Lupas q-transform has first appeared in the study of the Lupas q-analogue of the Bernstein operator. Given 0 < q < 1 and f is an element of C[0, 1], the Lupas q-transform is defined by Lambda(q)(f; x) Pi(infinity)(k=0) ... -
Determination of the smallest-greatest uni-nullnorms and null-uninorms on an arbitrary bounded lattice L
(World Stientific Publishing, 2023)In this paper, we study uni-nullnorms and null-uninorms on bounded lattices, which are generalizations of uninorms, nullnorms, t-norms and t-conorms. We construct two uni-nullnorms and two null-uninorms on a bounded lattice ... -
Sexual shape dimorphism in Bufo verrucosissimus (Pallas, 1814) from Lake Borçka Karagöl, Türkiye
(Hungarian Natural History Museum, 2023)Sexual dimorphism, i.e., differences in morphology between sexes of a species caused by intersexual differences in the strength or direction of sexual or natural selection, is preva-lent throughout the animal kingdom. ... -
A new water-soluble zinc azaphthalocyanine containing azo groups: synthesis, characterization, fastness and antibacterial properties on cotton fabric
(E.U. Printing and Publishing House, 2023)A novel water-soluble zinc azaphthalocyanine containing azo groups (Azo-ZnAzaPc) was synthesized and characterized using FT-IR, H-1 NMR, C-13 NMR, UV-vis, MS and elemental analysis. A dyeing experiment was performed on ... -
Variation in size and shape: sexual dimorphism in the southern banded newt, Ommatotriton vittatus (Caudata: Salamandridae)
(Springer, 2023)One of the main factors creating intraspecific morphological variation, sexual dimorphism (SD) could be expressed as adult male and female animals having different body sizes or shapes. Female-biased sexual dimorphism has ... -
Treatment of wastewater containing organic pollutants in the presence of N-doped graphitic carbon and Co3O4/peroxymonosulfate
(Springer, 2023)The disposal of organic pollutants is one of the important research topics. Some of the studies in this field are based on the degradation of organic pollutants with a catalytic agent. The cobalt tetraoxide/peroxymonosulfate ... -
Microplastic pollution and human risk assessment in Turkish bottled natural and mineral waters
(Springer, 2023)Microplastics (MPs), which arise from the deterioration of larger plastics that are frequently used in daily life and are smaller than 5 mm in size, are found in many environments and can pose a serious threat to human ... -
Prevalence of microplastics in commercially sold soft drinks and human risk assessment
(Elsevier, 2023)Due to the increasing global plastic production and use in recent years, the amount of microplastic (MP) accumulating in the environment has also increased. This microplastic pollution potential has been documented mostly ... -
Microplastic contamination and risk assessment in table salts: Turkey
(Elsevier, 2023)In this study, the characterization of microplastics of table salts (n = 36) was determined by FT -IR. Then, individuals' exposure to microplastics from table salt consumption was calculated with a deterministic model, and ... -
Mitochondrial cytochrome oxidase I variation in Asian tiger mosquito (Aedes albopictus): Determination of the different and multiple introduction situations in Turkiye
