Expansive clays can cause major problems for urban development (roads, railways, infrastructure, etc.); therefore, reducing the swelling potential of has always been a concern in geotechnical field. The presented paper investigates effect polypropylene reinforcement fibers on and shear strength clay. samples studied were taken from clayey region Mila, located northern east Algeria. experimental...

Cytotoxic brain edema, due principally to astrocyte swelling, is a major neurological complication of the acute form of hepatic encephalopathy (HE) (acute liver failure, ALF), a condition likely caused by elevated levels of brain ammonia. Potential mediators of ammonia-induced astrocyte swelling include oxidative/nitrosative stress (ONS), the mitochondrial permeability transition (mPT), mitogen...

Sodium alginate (SA) and gelatine (G) based hydrogels for biomedical applications, such as wound dressing, were crosslinked by calcium chloride (CaCl2) or glutaraldehyde (GTA) in order to overcome their exudates solubility. Swelling behaviour of prepared hydrogels in phosphate buffered saline with different pH value at 37 ° C was compared. It was proved that the crosslinking agent concentration...

OBJECTIVE The aim was to apply various maneuvers to perturb the volume of cultured chick cardiac myocytes and to evaluate the association between the swelling-activated chloride conductance and membrane distention. METHODS Swelling of single chick heart cells was induced by (1) reduction of external osmolarity; (2) elevation of intracellular osmolarity; (3) isosmotic urea uptake; and (4) posi...

Swelling of a commercial 5 Ah lithium-ion cell with a nickel/manganese/cobalt-oxide cathode is investigated as a function of the charge state and the charge/discharge rate. In combination with sensitive displacement measurements, knowledge of the electrode configuration within this prismatic cell's interior allows macroscopic deformations of the casing to be correlated to electrochemical and me...

The characteristic of expansiveness represented by swelling pressure is considered as major parameter in design of engineering structures. In order to determine the potential expansion, the swelling pressure experiments are usually conducted. In the present study, neuronets have been used to predict swelling pressure of undisturbed as well as remolded soils from given geotechnical parameters su...

In Kingdom of Saudi Arabia, there are several areas where expansive soil exists in the form of variable-thicknesses layers in the developed regions. Severe distress to infrastructures can be caused by the development of heave and swelling pressure in this kind of expansive shale. Among the various techniques for expansive soil mitigation, the removal and replacement technique is very popular fo...

1 In this study, we have used isolated brain mitochondria to investigate the effects of superoxide anions (O(2)(-)) on mitochondrial parameters related to apoptosis, such as swelling, potential, enzymatic activity, NAD(P)H, cytochrome c release, and caspase activity. 2 Addition of the reactive oxygen species (ROS) generator KO(2) produced brain mitochondrial swelling, which was blocked by cyclo...

Swelling behavior is an electrochemical mechanical property of articular cartilage. It plays an important role in weight bearing and joint lubrication. In this study, the altered transient and inhomogeneous swelling behavior of the degenerated articular cartilage was observed and quantified in situ using ultrasound. Three groups of bovine patellar articular cartilage samples (n = 10 x 3) were o...
