A case study

Pages 24- 29 Salah Gasim Ahmed Abstract Gears play a major role in power transmission. A precise knowledge of the stresses on gear tooth during operation is very essential in designing a reliable gear transmission system. This paper analyses the stresses on gear tooth, at both tension and compression sides, of the tooth. The analysis of the tooth strength

Pages 30-40 Osama Farid, Abdul Rehman Memo, John Robinson and Steve Tarleton Abstract Polymer crosslinking has significant importance in the relevant retrofitting of the microstructure of polymer network in terms of polymer swelling, membrane performance and its stability. This research focused on investigating the sorption influence on membrane selectivity in terms of measuring swelling of polydimethylsiloxane (PDMS) at varying

Pages 41-48 Emad Yousif, Hadeel Adel, Raghad Haddad and Rahimi Yusop  Abstract Five coordination complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn (II) metal with [2-thioacetic acid benzothiazole] were prepared in an alcoholic medium and used as photostabilizer for polyvinyl chloride against degradation. PVC was mixed with these complexes in a THF solvent to form a modified PVC in

Pages 49-57 Sheelan M. Hama Al – Barazinji Abstract This research includes a study of the effect of adding steel fibers extracted from old tires from cars (which are now available in abundance in Iraq) to polymer concrete. The efficiency of these fibers is compared with imported fibers. These two types of fibers were added with percentages of

Pages 58-63 A. Sofi, Gaurav Sharma and Shakil Kumar Abstract The use of fly ash in concrete today is an important subject and is growing in importance day by day. Using fly ash in concrete may provide both economical advantages and better properties in the production of concrete. Besides, concretes produced with different replacement ratios of fly ash
