Abstract

The development of the chemical composition gratings (CCGs) is described, and the influencing factors on reflectivity of CCGs in hydrogen‐loaded germanosilicate fibers have been studied.Experimental results show that improving the initial fiber Bragg grating (FBG) strength and enhancing the hydrogen concentration in FBGs inscription help to improve the reflectivity of the CCGs, and using different laser pulse energy of fabricating the FBGs has little effect on the reflectivity of CCGs. Finally the reasons of improving the reflectivity of CCGs are also discussed. Β© 2011 Wiley Periodicals, Inc.

Fried sweet potato slices were prepared from yellow (Mabrouka) and orange (Abees) tubers. Some chemical and organoleptic qualities were studied. Changes in these qualities which occurred during storage for 3 months at room temperature were also investigated. The results obtained led to the following

## Abstract Material behaviour in a corroding medium varies depending on its properties. These properties are affected by the treatment, alloy elements and last but not least its surface condition. The sensitivity of a material to iron scale formation and decarburisation limits some technological p
