I discuss the relation between the Qiu-Sterman effects on one hand and the Collins, Sivers and Boer-Mulders effects on the other hand. It was suggested before that some of these effects are in fact the same, thus providing interesting connections between transverse-momentum dependent twist-2 functions and collinear twist-3 functions. Here I propose an alternative way to reach similar conclusions.

BACKGROUND: Betaine has been shown to be antioxidantand methyl donor effects in our recent studies. OBJECTIVES: Inthe present study, the antioxidant and methyl donor properties ofbetaine in levodopa/benserazide-mediated hyperhomocysteinemiaand levodopa-induced oxidative stress in rat's kidney wereexamined. METHODS: Sprague-Dawley male rats were dividedinto levodopa (LD), Betaine (Bet.), levodop...

stability of the π-π stacking interactions in the ben||n-substituted-coronene complexes was studied using the computational quantum chemistry methods (where ben is benzene and || denotes π-π stacking interaction, and n-substituted-coronene is coronene molecule which substituted with different number of n atoms). the results reveal simultaneous effects of structure and number of heteroatom on th...

Cutaneous leishmaniasis ( CL) is a parasitic infection which has been treated with different drugs without any conclusive treatment. In this case control study, the therapeutic effect of Thio- Ben ( combination of thioxolon and benzoxonium chloride) was compared to intralesional meglumine antymoniate ( glucantime) treatment. Two groups of patients were chosen at random, first group ( test, n1= ...

The Diamedica non-rebreathing valve has been developed for use in draw-over anaesthesia and can be positioned at the common gas outlet. Its performance was evaluated against the Laerdal, Ruben and Ambu valves under laboratory conditions. Valve resistance during inspiration and expiration was simulated over a range of constant flow conditions. During flows ranging from 5 to 45 l.min(-1) , the Di...

stability of the π-π stacking interactions in the ben||substituted-coronene and hfben||substituted-coronene complexes was studied using the computational quantum chemistry methods (where ben and hfben are benzene and hexaflourobenzene, || denotes π-π stacking interaction, substituted-coronene is coronene molecule which substituted with four x groups, and x= nh2, ch3, oh, h, f, cf3, cn and no). ...
