The partial differential equations governing this phenomenon were transformed into coupled nonlinear ordinary differential equations with suitable similarity transformations. These equations were then solved by numerical technique known as Keller Box method. The various parameters such as Prandtl number (Pr), velocity ratio parameter( �), Williamson parameter ( λ) and Radiation parameter (R) and non linear stretching parameter (n) determining the velocity and temperature distributions, the local Skin friction coefficient and the local Nusselt number governing such a flow were also analyzed. On analysis it was found that the Williamson fluid parameter ( λ) decreased both the fluid velocity whereas an increase in ( λ) increased wall skin-friction coefficient. The wall temperature gradient increased with an increase in Pr but decreased with radiation parameter R.","PeriodicalId":7399,"journal":{"name":"American Chemical Science Journal","volume":"27 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87228898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coordination of the organic ligands, the environment of the central ion and thermal behavior of the synthesized compounds are elucidated by vibrational spectroscopy and thermal analysis. The comparative consideration of the relative intensities and the spatial structures of Nickel - Nicotinate, and the complexes synthesized shows that the new coordination compounds differ from each other and the original components as they have individual crystal lattices. Electronic spectra of the diffuse reflection of the synthesized compounds have shown that coordination compounds of divalent Nickel have an octahedral geometry. It is experimentally verified that the compounds synthesized can be used as cotton growth stimu lators.","PeriodicalId":7399,"journal":{"name":"American Chemical Science Journal","volume":"192 2","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91416320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
