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. ... إقراء المزيد

"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 ... إقراء المزيد

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 ... إقراء المزيد

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 ... إقراء المزيد

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 ... إقراء المزيد

Recommendations for the Development and Reform of Microtia and Atresia Services
Background: The initial step in setting up standardized microtia- atresia service is investigating the current status of the service and comparing this to internationally recognized guidelines or care standards. Inmany countries, documented information aboutmicro- tia care is lacking. This study is an initiative to guide reform efforts of national microtia service in any country. The UK care standards for microtia-atresia ... إقراء المزيد
