This research investigates the seasonal ground heave/settlement of an area covered by expansive soil Cyprus called Nicosia marl, highlighting degree influence main causal factors. For this purpose, existing geotechnical data from archives Geological Survey were first collected and processed to compile maps key parameters in study area. In order estimate movements area, Earth Observation (EO) te...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
The effect of hormones on cell volume was studied in isolated perfused rat liver by assessing the intracellular water space as the difference between a [3H]inulin- and a [14C]urea-accessible space. The intracellular water space (control value 559 +/- 7 microliters/g of liver; n = 88) increased on addition of insulin (35 nM) or phenylephrine (5 microM) by 12 or 8% respectively, whereas it decrea...
Hypertonic shrinkage of dog red cells caused rapid activation of Na/H exchange and rapid deactivation of [K-Cl] cotransport. Hypotonic swelling caused delayed deactivation of Na/H exchange and delayed activation of [K-Cl] cotransport. Okadaic acid stimulated shrinkage-induced Na/H exchange and inhibited swelling-induced [K-Cl] cotransport. The data are compatible with the kinetic model of Jenni...
This paper presents a modified Biot’s model for describing the hydromechanical behaviour of Callovo-Oxfordian Argillite (COx) Claystone. The COx Claystone exhibits significant deformation during water desaturation/resaturation, and standard is unable to predict large shrinkage/swelling material. authors then introduced an additional swelling/shrinkage law simulate deformations upon changes in c...
nowadays,tourism industry considered as one of the main sources of income of a country.unfortunately and despite of owning plenty of cultural historical and natural attractions, iran has not reached to a proper position in this field. besides, the historical cities of a country are considered as the income resource and national wealth of it. qazvin with a rich cultural precedent, have suitable ...
