The interaction between Hg2+ ions and endogenous thiols (RSH), such as glutathione (GSH), cysteine (Cys), homocysteine (Hcy), cysteinyl-glycine (CysGly) and ?-glutamyl-cysteine (?-GluCys), leads to the swift formation of the Hg(II)-thiol complexes. We investigated the potential capacity of Hg(II)...

Alternative theorems have proved to be important in deriving key results in optimization theory like the existence of Lagrange multipliers, duality results, scalarization of vector functions, etc. Since the pioneering result due to Julius Farkas in 1902 concerning his alternative lemma which is w...

The increase of UV-B radiation may be a challenge for wheat production systems in Southern Chile. Previous reports had shown that increased UV-B radiation decreased wheat yield by affecting both grain number and grain weight. The objective of the present study was to evaluate the response of grai...

In [2], M. Carr and S. Devadoss introduced the notion of tubing on a finite simple graph G. When G is the linear graph Ln, with n vertices, the polytope K Ln is the Stasheff polytope or associahedron. Our goal is to describe a partial order on the set of tubings of a simple graph, which generaliz...
