Presence of swelling soils under the foundations of civil engineering structures particularly lightly loaded structures has caused serious damages around the globe due to their differential up heaving. In this paper, based on the results of swell tests on bentonite mixed clay, correlations for predicting the swelling parameters (i.e., swell potential and swell pressure) have been proposed. Mixi...
Results of laboratory tests on specimens produced from subsoil studies were evaluated tocharacterize geotechnical properties of Tabriz Marl. It was concluded that, Tabriz Marl may be considered as a high liquid limit silt or clay (MH & CH). Range of changes of index, physical and mechanical properties of the Tabriz Marl are comparatively vast. Correlation between these properties has been intro...
expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. these soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. this paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...

The volume-sensitive chloride current (ICl,swell) is found in the mammalian myocardium and is activated by osmotic swelling. The goal of this study was to examine the importance of the tyrosine kinases focal adhesion kinase (FAK) and Src kinase in cardiac ICl,swell regulation. Neonatal rat ventricular myocytes were cultured on collagen membranes and infected with adenovirus expressing beta-gala...
The geotechnical behaviour of expansive clay soils is investigated by looking into the geomorphologic, geological and climatic conditions and mineralogical composition of the soils in the study area. The geotechnical results are linked with the performance of the foundation as well as structures. Since swell potential and swell pressure are key properties of expansive soils, the swell parameter...
Regulation of swelling-activated Cl(-) current (I(Cl,swell)) is complex, and multiple signaling cascades are implicated. To determine whether protein tyrosine kinase (PTK) modulates I(Cl,swell) and to identify the PTK involved, we studied the effects of a broad-spectrum PTK inhibitor (genistein), selective inhibitors of Src (PP2, a pyrazolopyrimidine) and epidermal growth factor receptor (EGFR)...
OBJECTIVE Myocardial swelling occurs during endotoxic shock. The hypothesis that swelling-activated Cl- current (ICl,swell) activates during endotoxic shock was tested. METHODS Endotoxic shock was induced by intravenous lipopolysaccharides (10 mg/kg) in guinea pigs. The effects of ICl,swell blockers on the cardiac action potentials in papillary muscles and on the ICl,swell in single ventricul...
PURPOSE To determine the potential role of ClC-3, a PKC-inhibitable Cl(-) channel, in mediating the swelling-activated Cl(-) current (I(Cl,swell)) of native bovine nonpigmented ciliary epithelial (NPE) cells. METHODS Native bovine NPE cells were freshly harvested by enzymatic digestion. Whole-cell currents were recorded by patch-clamp measurements either in the presence or absence of a functi...
Use of engineered landfills for the disposal of industrial wastes is currently a common practice. Bentonite is attracting a greater attention not only as capping and lining materials in landfills but also as buffer and backfill materials for repositories of high-level nuclear waste around the world. In the design of buffer and backfill materials, it is important to know the swelling pressures o...
