we present a case of infantile intussusception treated successfully using hydrostatic reduction, highlighting the importance of non-surgical techniques as the first line of management for this entity. physicians should strive for mastery over such techniques by extensive training to prevent unwanted surgical procedures in such cases.

Vortex extrusion (VE) is a severe plastic deformation technique which is based on the synergies between high strain accumulation and high hydrostatic pressure. Such a high amount of pressure, places a mandate to seek the method for investigation of the load under processing conditions. For this, kinematically admissible velocity field and upper bound terms based on Bezier formulation are develo...

We report a detailed study of the behavior (shapes, experienced forces, velocities) of giant lipid vesicles subjected to a shear flow close to a wall. Vesicle buoyancy, size, and reduced volume were separately varied. We show that vesicles are deformed by the flow and exhibit a tank-treading motion with steady orientation. Their shapes are characterized by two nondimensional parameters: the red...

Abstract We have designed and built a versatile testing device to perform hydraulic fracturing experiments under true triaxial conditions. The device, based on stiff biaxial frame that can be installed in servocontrolled press, accommodate cube rock samples of up 150 mm-edge. Using low-permeability known as Blanco Mera granite, we performed series tests across range confining pressures includin...

The expression of effective stress proposed by Terzaghi has always been questioned. Many correction formulas are modification pore pressure term. factor is related to porosity, contact area and other factors. When the particles in point contact, that Terzaghi, while for surface particles, actual increases produced passing through based on stress. There many factors affect development pressure, ...

The breaking of seed dormancy induced by stress [1] is extremely important with regard to the acceleration of germination process [1,2]. Abiotic stress processes, just like high hydrostatic pressure (HHP), are applied in several biotechnological studies, mainly because HHP induces changes in physiological and biochemical processes [3]. Pretreatment with a stress induction tool can be lethal or ...
