Background Corticotropin-releasing factor (CRF) mediates our body's overall responses to stress. The role of central CRF in stress-stimulated colonic motility is well characterized. We hypothesized that transient perturbation in expression of enteric

The influence of supplementary cementitious materials (SCMs), namely silica fume, metakaolin, fly ash and ground granulated blast-furnace slag, on the engineering properties of high strength concrete (HSC) has been investigated in this study. Workabi

Experimental results of creep, shrinkage, swelling, modulus of elasticity and strength of 18 types of concrete after 30 years are presented. While the compressive strength of dry-stored concrete was greater than that of wet-stored concrete, the modul

This paper presents the results of experimental work on short- and long-term mechanical properties of high-strength concrete containing different levels of silica fume. The aim of the study was to investigate the effects of binder systems containing

Shrinkage and creep results are presented for different types of masonry mortars having a wide range of strength. The range of values implies that the type of mortar has an appreciable influence on deformation of masonry. The results are analysed, to

The effect of metakaolin (MK) on the creep and shrinkage of concrete mixes containing 0%, 5%, 10%, and 15% MK has been investigated. The results showed that the early age autogenous shrinkage measured from the time of initial set of the concrete was

A theory for drying creep is proposed based on the stress concentrations arising from the presence of a rigid inclusion and a hole in a surrounding medium subjected to an external stress. The analogy is made with cement paste where there are some por
