Islam; Challenges and Opportunities
Undoubtedly Islamic Revolution of Iran has been the source of Islamic awakening in the middle-east. Therefore Islamic Republic of Iran plays the role of an example and a director of political developments in the region. Islamic awakening in Arab countries has been able to question the dominant discourse of dictators in the middle-east region and topple their regimes. These developments include ...
متن کاملStudy on Utilization of Carboxyl Group Decorated Carbon Nanotubes and Carbonation Reaction for Improving Strengths and Microstructures of Cement Paste
Carbon nanotubes (CNTs) have excellent mechanical properties and can be used to reinforce cement-based materials. On the other hand, the reaction product of carbonation with hydroxides in hydrated cement paste can reduce the porosity of cement-based materials. In this study, a novel method to improve the strength of cement paste was developed through a synergy of carbon nanotubes decorated with...
متن کاملDecalcification shrinkage of cement paste
Decalcification of cement paste in concrete is associated with several modes of chemical degradation including leaching, carbonation and sulfate attack. The primary aim of the current study was to investigate the effects of decalcification under saturated conditions on the dimensional stability of cement paste. Thin (0.8 mm) specimens of tricalcium silicate (C3S) paste, white portland cement (W...
متن کاملUnderstanding the Ureter: Challenges and Opportunities.
The ureter is possibly the least studied and most poorly understood organ of the urinary tract. The pathophysiologic basis underlying the use of α-blockers to improve ureteral stone passage or to treat ureteral stent symptoms is poorly understood. This, in part, may explain why clinical studies of medical expulsive therapy for ureteral stone passage are fraught with conflicting data. Methods to...
متن کاملOnset of cohesion in cement paste.
It is generally agreed that the cohesion of cement paste occurs through the formation of a network of nanoparticles of a calcium-silicate-hydrate ("C-S-H"). However, the mechanism by which these particles develop this cohesion has not been established. Here we propose a dielectric continuum model which includes all ionic interactions within a dispersion of C-S-H particles. It takes into account...
