The stable phosphonate derivatives have easily synthesized by the reactions involving trialkyl(aryl) phosphites and dimethyl acetylenedicarboxylate in the presence of 4-nitrophenol and/or acid chlorides, dialkyl(aryl) phosphites and N-methylimidazole at 70 oC under solventfree conditions.
This paper introduces a promising user study approach, Three in One User Study (TO US). The approach is applicable for SME-scale design projects with limited resources and in quest for semi radical innovation. TO US is built on applying a set of studies in parallel, which speeds up and lightens the process. It also follows the logic of problem solving in design practice. In TO US face-to-face c...
When organisations commit themselves to work with urban poor communities, they are often faced with difficult choices. Should they confront and challenge the powers that determine and rule their lives or should they work around the problem and negotiate? What do they need themselves to be in a position of strength, should they choose the latter path? Can their interests be served if they choose...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
