Effects of Thickness and Ag Layer Addition on the Properties of ZnS Thin Films
Zinc sulfide (ZnS) thin films, with different thicknesses and different silver (Ag) middle layer thickness, were prepared on glass substrates using thermal evaporation. The structural and optical properties of ZnS thin films were characterized by X-ray diffraction and UV-VIS-NIR spectrophotometer. The X-ray diffraction analyses indicated that ZnS films have cubic structure with (111) preferential orientation, whereas the diffraction patterns sharpen ... Read more

The Effect of the Accelerated Laboratory Ageing Factors on Linen Textiles Dyed with Turmeric Dye
Archaeological linen textiles in uncontrolled museums are exposed to many different damage factors. It is noticed in some Egyptian Museums that the differences in temperature and use of inappropriate light bulbs are the most enemies of dyed historical textiles. This article presents interesting results about the effect thermal and light ageing on optical,chemical and mechanical characterization of dyed linen textiles. ... Read more

"Effect Of Curing Period On Geopolymer Concrete Incorporating GGBS ,Fly Ash And Silica Fume
ABSTRACT : Cement industry is one of the major contributors to the emission of greenhouse gasses. So, efforts are needed to make concrete more environmental friendly by using fly ash which helps in reduce global warming as well as fly ash disposal problem. This paper presents study of effect of curing period on mechanical properties of fly ash based geopolymer ... Read more

"Structural Behavior of Axially Loaded Geopolymer Reinforced Concrete Short Columns Subjected to Elevated Temperatures"
ABSTRACT: The current experimental study included testing ten geopolymer concrete short columns and ten conventional concrete short columns under vertical axial loads. In addition, the behavior of the tested columns was studied in terms of ultimate load , cracking loads , modes of failure, toughness, stiffness and ductility at ambient temperature and elevated temperature of 3000C &5000C for exposure periods ...

The effect of saline water magnetization on physiological and agronomic traits of some bread wheat genotypes
The present work relates to estimate the effect of magnetically-treated saline water on physiological and agronomic traits of 22 bread wheat genotypes and to determine the changes in soil properties. Replicated pot experiments involving potable water, saline water (2500 and 5000 ppm) and magnetically treated (2500 and 5000 ppm saline water) were conducted in greenhouse during 2017/2018 and 2018/2019 winter ...

Grain Yield Stability of New Bread Wheat Genotypes (Triticum aestivum L.) under Normal and Heat Stress Conditions
FORTY-TWO bread wheat genotypes (Triticum aestivum L.) were evaluated in eight environments in Egypt: two locations and two planting dates during the two 2016-2017 and 2017-2018 growing seasons. The objectives of this study were to estimate grain yield, number of spikes plant-1, 1000-kernel weight and plant height of these 42 bread wheat genotypes under different environments and to determine their ...

DETECTION OF PROTEINS AS ORGANIC ADDITIVE IN FLOORING MORTARS USED IN EXCAVATED REMAINS FROM ANBA SHENOUTE MONASTERY, SOHAG, EGYPT
Detecting organic additives in ancient mortars is significant to be carried out as far as mineralogical, chemical, and physical investigations. That characterisation allows understanding the technology of those mortars and is important to make appropriate decisions in conservation works. Previous characterisations of organic additives in mortars, including jointing and flooring ones used in the Red Monastery located next to Anba ... Read more
