We observed nuclear swelling in glutamate (Glu)-treated astrocytes that was concomitant with but independent of astrocytic cell swelling. We confirmed Glu-induced nuclear swelling with nuclei isolated from astrocytes. Ammonia is metabolically related to Glu and could induce a nuclear swelling in intact astrocytes but shrinkage in isolated nuclei. Other compounds such as glutamine, aspartate, ta...

Expansive clayey soils are highly moisture sensitive with respect to stress, deformation and strength. These soils exhibit extreme variation in deformation such as heaving, loss of shear strength under certain Moisture Content and settlement and shrinkage as the Moisture Content alters. Swelling is the process of increase in volume of soil that occurs during its interaction with water. Expansiv...

This work deals with an experimental and numerical approach to determining the differed behavior of compressed wood elements subjected creep loading. An protocol is associated a mechanical model, whose purpose isolate effects from those shrinkage-swelling, while allowing for long duration test be conducted. The based on compression applied five wooden columns disposed in climatic room one year....

Aleppo pine (Pinus halepensis Mill.) is the main forest species of Algeria occupying more than 35% total area country. However, physicomechanical and thermal characteristics Algerian P. wood are not well-known. This research investigates physical (moisture, density, swelling, shrinkage), mechanical (bending strength modulus elasticity), (mass loss under combustion pyrolysis as well conductivity...

Objective(s) In this study, a kind of pH sensitive composite membrane was prepared and drug permeation through it was investigated in terms of pH. Rationale of this study originated from the fact that a pH change which may be a result of a disease state in the body can trigger drug release. Materials and Methods  Here, a kind of pH sensitive composite membrane containing different nanoparticle ...

Background: Geotechnical engineers working on the ground face a common obstacle of unsuitable soil. Expansive soil is one soils vulnerable to high loads and unstable. Properties such as permeability, low bearing capacity, compression, swelling shrinkage behavior, strength stiffness are all characteristics an expanding weaker than other types due these characteristics. Objective: T...

Effects of the heat treatment parameters were evaluated relative to some physical and mechanical properties poplar wood (Populus alba L.) with use two prominent multi criteria decision-making (MCDM) techniques: Entropy The Technique for Order Preference by Similarity Ideal Solution (TOPSIS). To meet this objective, test samples heat-treated at 120, 150, 180, 210 °C 2 4 h in a laboratory-scale o...

Although the Na(+)/K(+) pump is one of the key mechanisms responsible for maintaining cell volume, we have observed experimentally that cell volume remained almost constant during 90 min exposure of guinea pig ventricular myocytes to ouabain. Simulation of this finding using a comprehensive cardiac cell model (Kyoto model incorporating Cl(-) and water fluxes) predicted roles for the plasma memb...
