In this paper, we introduce the notions of a derivation and a generalized derivation determined by a derivation for a complicated subtraction algebra. We give some related properties and equivalent conditions which derivations ...

Probable source materials and production technologies of neolithic pottery from Catalhoyuk were studied with micromorphological and archaeometrical methods, seeking to shed light on the established techniques and appropriate ...

Novel 1,3-dialkylperhydrobenzimidazolinium chloride salts were prepared as precursors of N-heterocyclic carbenes 3a-e by reacting N,N'-dialkylcyclohexandiamine, triethyl orthoformate and ammonium chloride. The salts were ...

Macrofungi samples were collected from Goksun (Kahramanmaras) district between 2005 and 2007. As a result of field and laboratory studies, 110 taxa belonging to 33 families and 70 genera in Ascomycetes and Basidiomycetes ...

Pyridine-based macrocycles were prepared by treating 2,6-bis[[2'6'-bis(bromomethyl)-4'-methylphenoxy]methyl]pyridine 3 with the appropriate chiral aminoalcohols. The enantiomeric recognition of these macrocycles bearing ...

Phosphorus (P) deficiency and low P-use efficiency are induced by soil properties, especially in calcareous soils, which are dominant in semi-arid regions of the world such as the Mediterranean region. Alternative approaches ...

The Southeast Anatolian Orogen resulted from collision of the Afro-Arabian and the Eurasian plates following the Cretaceous to Miocene closure of the southern Neotethyan oceanic basin. In this orogenic belt, there are ...

The Tauride-Anatolide continent, stretching for c. 900 km across western and central Turkey, is one of the world's best example of a subducted, exhumed passive margin within a collisional orogen. Twelve widely separated ...

For over ten years, there has been a considerable interest in determination of acrylamide in foodstuffs. It was known that both protein-rich and carbohydrates-rich foods cooked at high-temperatures can cause acrylamide ...

The title compound, C17H15N2O2+center dot Cl-center dot H2O, was synthesized from benzimidazole and furfryl chloride in dimethylformamide. The cationic benzimidazolium ring is connected to two furan rings via methylene ...
