In this work we propose the synthesis of thiazolidine and bisthiazolidine derivatives, and the structure of these compounds were studied using elemental analysis, IR, H-NMR and C-NMR spectroscopy. Tautomeric properties and conformations were investigated by semi-empirical AM1, MNDO and PM3, and ab initio calculations to illustrate the conformational analysis. All calculations lead to the same r...

A proper treatment of K-mixing is the key to understanding K-isomers. Here, we present a method based on the projected shell model. This method differs from the usual description of multi-quasiparticle states by introducing a transformation to the laboratory frame and a subsequent configuration mixing in that frame. It allows a quantitative study on the degree of K-violation through direct calc...

We give an explicit canonical transformation which transforms a generic chiral 2D dilaton gravity model into a free field theory.

Abstract. The atmospheric chemistry of halogenated species (Cl, Br, I) participates in the global chemical sink tropospheric ozone and perturbs oxidising capacity troposphere, notably by influencing lifetime methane. Global chemistry–climate models are commonly used to assess budget its sensitivity emissions precursors, as well project long-term evolution. Here, we report on implementation sour...

A drug developed for human use classically goes through a number of steps, including discovery, extensive preclinical studies for safety in experimental animals, and then human safety and efficacy studies. The Food and Drug Administration (FDA) requires successful completion of all the above tasks before approval for therapeutic use in human beings. The exciting advances in human genomics and c...
