This paper focuses on approximate reasoning based on the use of similarity spaces. Similarity spaces and the approximated relations induced by them are a generalization of the rough set-based approximations of Pawlak [17, 18]. Similarity spaces are used to define neighborhoods around individuals and these in turn are used to define approximate sets and relations. In any of the approaches, one w...

Coconut water (Cocos Nucifera) is shown to be a source of essential elements present in the form low-molecular weight stable complexes known for their bio-availability. The total element concentrations were range 0.2–2.7, 0.3–1, 3–14 and 0.5–2 ppm Fe, Cu, Mn, Zn, respectively, varied as function origin nut its maturity. Speciation was investigated by size-exclusion chromatography - inductively ...

As a continuation of the study on using the tetrazolate ligands to construct coordination polymers, two isomorphous 3D coordination polymers built on Δ-chain topological rod-shaped SBUs have been synthesized with formulae [M(2)(μ(3)-OH)L(1)L(2)](n) (5-amino-1H-tetrazole (HL(1)), 2,3-pyrazinedicarboxylic acid (H(2)L(2)) and different 3d spin carriers (M = Mn(II), 1 and Co(II), 2)). The SBU consi...
