Mitigation of greenhouse gas emissions is becoming a significant factor in all industries. Cement manufacturing one the industries responsible for emissions, specifically carbon dioxide emissions. Pozzolanic materials have long been used as cement additives due to pozzolanic reaction that occurs when hydrated and formation cementitious material similar cement. In this study, shale, which common...

The determination of rock strength holds paramount importance in the field engineering geology. In this study, we conduct a comprehensive geostatistical evaluation unconfined compressive (UCS) within 100 km2 area situated northeast Jeddah, Saudi Arabia. UCS values were indirectly estimated using an empirical equation based on Schmidt hammer rebound method, resulting range strengths from 9.2 to ...

the use of recycled bassanite, produced from gypsum wastes, in ground improvement projects is initiated recently in japan to eliminate the huge quantities of gypsum wastes. meanwhile the use of recycled bassanite has a positive effect on the environment and economy, it has many challenges. these challenges are related to the release of fluorine more than the standard limits results in contamina...

Using a microchannel assay, we demonstrate that cells adopt distinct signaling strategies to modulate cell migration in different physical microenvironments. We studied α4β1 integrin-mediated signaling, which regulates cell migration pertinent to embryonic development, leukocyte trafficking, and melanoma invasion. We show that α4β1 integrin promotes cell migration through both unconfined and co...
