t-closure operators
(Taylor & Francis Ltd, 2019)In this study, based on the knowledge of the existence of t-norms on an arbitrary given bounded lattice, we introduce t-closure operators with the help of a t-norm on the lattice and a subset of the lattice including the ... -
A T-partial order obtained from T-norms
(2011)A partial order on a bounded lattice L is called t-order if it is defined by means of the t-norm on L. It is obtained that for a t-norm on a bounded lattice L the relation a ?T b iff a = T(x,b) for some x ? L is a partial ... -
Taxonomic assessment and distribution of common toads (Bufo bufo and B. verrucosissimus) in Turkey based on morphological and molecular data
(Brill, 2020)The Bufo bufo species group includes four species distributed in the western Palearctic: B. bufo. B. eichwaldii, B. spinosus and B. verrucosissimus. Both B. bufo and B. verrucosissimus are known to occur in Turkey, but ... -
Taxonomic notes on Tragopogon, and two newly described taxa from Anatolia
(Wiley, 2016)Tragopogon L. (Asteraceae) includes several cryptic species that are geographically widespread and morphologically similar. Here, we describe two new native species from eastern Anatolia. Through both morphological and ... -
Tea-based biochar-mediated changes in cation diffusion homeostasis in rice grown in heavy metal (loid) contaminated mining soil
(Elsevier, 2023)Foreseeable future scenarios highlight the urgency of applying eco-safe avoidance methods or tolerance to heavy metal(loid) (HM) stress in agricultural production areas of contamination. The analyses show that the Ni, Mn, ... -
Teaching mixed-level classes with a vygotskian perspective
(Elsevier Science Bv, 2015)One of the biggest challenges that teachers face is the mixed-level classes, where students have different abilities, backgrounds and interests. All classes can be defined as 'mixed' since no student is the same as the ... -
Temperature dependent local atomic displacements in NaSn2As2 system
(Iop Publishing Ltd, 2019)NaSn(2)As(2 )is mechanically exfoliable layered van der Waals (vdW) Zintl phase that is getting interesting due to its low thermal conductivity and recently observed superconductivity. Here, we have investigated the ... -
