Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.
Technology Reports of Kansai University (ISSN: 04532198) is a peer-reviewed journal. The journal covers all sort of engineering topic as well as mathematics and physics. the journal's scopes are

This study is designed to investigate the role of (0,1,2 and 3.0% by weight) Portland cement, hydrated lime, gypsum and bitumen in the stabilization mechanisms of many lead contaminated Iraqi soils; as measured mechanically by a “mini” JET device and chemically by the gravimetric dispersion ratio method (as DR,%) in 1:2 soil:water solutions. From the “mini” JET results, cement was the best mechanical stabilizer in increasing both the critical shear stress (τc, pa) and the degree of hardness (DH) and hence reducing both the scouring depth (SD, mm) and the erodibility coefficient (kd cm3/N.s); followed by lime and bitumen. Gypsum has proved its failure as a mechanical binder and its calcium produced flocks seem to be very vulnerable against wet conditions and the energy of running water scouring force. To the contrary and as a chemical stabilizer, gypsum was superior in reducing the dispersion ratio (DR,%); followed by lime, cement and bitumen. In the case of lead mobility, gypsum was the best in reducing lead solubility and presumably its mobility in treated soil solutions; followed by bitumen, cement and lime with a stabilization efficiency (SE,%) of 93,90,59 and 54.9% respectively, but the formed gypsum calcium-clay flocks loaded with lead may be easily detached by the running water forces
The fuel cells of the electrolyte polymer membrane (PEMFC) and methanol fuel cell (DMFC) are one of the alternative energy sources of energy. This research aims to make the membrane material that environmentally friendly and inexpensive. The extract of the pineapple bark is fermented by the bacteria Acetobacter xylinum to produce nata de pina and the process of sulfonation is carried out with the help of microwaves. The Membrane is then characterized by measuring the capacity of the ion exchanger, contact angle, group analysis of functions with FTIR, degree of hercism, mechanical properties, proton conductivity, and morphological analysis with SEM. Characterization results indicate the best result of a well-sonicated membrane nata de pina is a 4-hour disulfonation membrane, with a capacity value of 3.47 mEq/g ion Exchanger, 112.05% degree of grazing 139.9. The resulting mechanical strength of the membrane increased significantly and the arrangement of cellulose fiber arrangement remained orderly
