STUDIES ON RUBBER MIXING PART 1

Safety studies on epigallocatechin gallate (EGCG) preparations. Part 1: genotoxicity.

Public interest in green tea has grown recently due to the potential health benefits from its consumption. Epigallocatechin gallate (EGCG), a principal polyphenolic component of green tea, is considered key to these healthful qualities. Although numerous studies have evaluated the anti-cancer effects of green tea and EGCG, few have examined the safety of EGCG consumption. The genotoxic potentia...

Experimental and CFD Studies on the Effect of the Jet Position on Mixing Performance

studies on properties of short fiber reinforced natural rubber composites

natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...

Molecular mixing in Rayleigh-Taylor instability. Part I: Global mixing

This paper describes experiments on the mixing produced by Rayleigh-Taylor instability between two miscible fluids. A layer of brine is placed over a layer of fresh water in a gravitational field, and the ensuing flow is visualized by laser-induced fluorescence and measurements are made of the concentration fields as the flow develops. It is found that largescale disturbances develop which prod...

STUDIES ON HYDRALAZINES - PART-1x1 PREPARATION AND ANTIMICROBIAL ACTIVITY OF 1 - (PHTHALAZIN- 1 '-YLAMINO)- 3-CHLORO-4-ARYL- 4H-(OR 4-METHYL)-2-AZETIDINONE

1- (Phthalazin-l'-yl-amino)-3-chloro-4-aryl-4H-(4o-rm ethyl)-2-azetidinones (3) were prepared by cycloaddition of-methyl substituted benzal hydrazinophthalazine (2) with chloro acetylchloride. The hydrazone (2) was synthesised by the condensation of 1- hydrazinophthalazine (1) with substituted aromatic aldehydes, ketones 7 acetophenones. 1- Hydrazinophthalazine was prepared from the phthal...
