Abstract Background Intussusception is the most common abdominal emergency in children. The first line treatment of uncomplicated pediatric intussusception enema reduction. Until now, there have been no multi-center studies comparing effectiveness and safety UGHR FGAR intussusception. aim this study was to compare two commonly used methods intussusception: ultrasound-guided hydrostatic reductio...

The objective of the present project was to study how high temperatures affect the different mechanical parameters of chalks. The general result is that both cohesion and the hydrostatic yield stress are typically reduced about 20 % in going from 20 to 130 C, but the magnitude of this reduction may be chalk type dependent.

The initiation, propagation, coalescence and failure mode of brittle jointed rock mass influenced by fissure water pressure have always been studied as a hot issue in the society of rock mechanics and engineering. In order to analyze the damage evolution process of jointed rock mass under fracture water pressure, a novel numerical model on the basis of secondary development in fast Lagrangian a...

purpose : to investigate the effects of mtp-131 on trabeculum cells cultured under hydrostatic pressure methods : glaucomatous human trabecular meshwork (gtm3) cells were divided into three groups: the mtp-131 group, the hydrostatic group, and the normal group. the mtp-131 group was pretreated with 1 µm mtp-131, and the cells were then cultured under 80 mmhg pressure for 24 hours. the normal gr...

a new chemical grouting method has been developed for conglomerate formations based on the experimental studies. due to the lack of chemical grouting experience of conglomerate formations, the testing programs were performed to evaluate the performance of chemical grouting in the water sealing of part of conglomerate foundation of karkheh earth dam using a combination of field and laboratory te...

sludge drying bed is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and studies of assumptions. in this study, the effect of hydrostatic suction and sludge chemical conditioning has been studied in the natural sludge dewatering optimization. at first, hydrostatic s...

Direct measurements have been made of the net volume flow through cellulose membranes, due to a difference in concentration of solute across the membrane. The aqueous solutions used included solutes ranging in size from deuterated water to bovine serum albumin. For the semipermeable membrane (impermeable to the solute) the volume flow produced by the osmotic gradient is equal to the flow produc...
