we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.
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...
This paper performs a meta-analysis of the effect on economic growth financial development and liberalization in European emerging markets compares with that advanced economies. A meta-synthesis 893 estimates extracted from 45 studies suggests finance has positive growth. Furthermore, our findings indicate synthesized size was smaller than Results meta-regression analysis test for publication s...

Caring for a child with a mental or physical disability is fraught with challenges. Therefore, the purpose of this study was to review the lived experiences of mothers with children with physical and mental disabilities. Materials and Methods: This study was per...
Recognition of the need for good research synthesis dates back almost half a century (c.f .WRIGHT MILLS, 1959), although it is far more recently that specific methods of synthesis have been developed. NOBLIT and HARE (1988) argue that such methods have emerged because of the failings, in the eyes of both positivists and interpretivists, of traditional literature reviews which, while giving an o...
The synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-Grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. Via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.
Today, most countries in the world are gearing up by innovation, seeking to increase productivity and improve their economic situation, and one of the important centers for innovative activities is the incubator centered companies. The majority of companies based in incubator centers are startups companies. Considering that the failure rate of new firms in the early years of formation is greate...
Meta-synthesis method is proposed to tackle with open complex giant system problems which cannot be effectively solved by traditional reductionism methods by a Chinese system scientist Qian, Xuesen (Tsien HsueShen) around the early 1990s. The method emphasizes the synthesis of collected information and knowledge of various kinds of experts, and combining quantitative methods with qualitative kn...
Introduction. Meta-synthesis methods may help to make more sense of information behaviour research evidence. Aims and objectives. The objectives are to: 1) identify and examine the theoretical research strategies commonly used in information behaviour research; 2) discuss metasynthesis methods that might be appropriate to the type of research studies normally encountered in information behaviou...
Qualitative meta-synthesis is an emerging method for synthesis of findings of qualitative studies. Based on a qualitative meta-synthesis study on the lived experiences of immigrant Asian nurses working in Western countries (Xu, 2007), this paper discusses several methodological issues and challenges encountered during the data collection and analysis processes and strategies used to resolve the...
