We present new laboratory observations of an advancing boiling front radiating from an injection point in a simulated geothermal reservoir. The Berea sandstone model is a 26 cm cube that is either heated to a dry 125°C, or saturated with 145°C steam in two separate testing configurations. Cool water is applied at the sample center, and the advancing boiling front is identified by a radial array...

BACKGROUND About 30% of women experience severe continuous low-back pain in labour, but limited options are available to reduce this pain especially in developing countries and remote areas. AIMS To evaluate the efficacy of subcutaneous sterile water injection in reduction of labour pain compared with placebo. METHODS One hundred (100) consecutive patients were enrolled in a double-blind ra...

To determine how fracture–vuggy structure, pressure, and injection–production mode influence displacement efficiency in the water flooding process in fracture–vuggy reservoirs, two types of models were built based on the characteristic of such reservoir: two fracture models with different fracture apertures and two fracture– vuggy models with different sizes of vugs. A series of twophase fluid ...

Few cases of high pressure water injection injuries of the foot have been reported. These cases suggest that only minimal soft tissue destruction results and that, with conservative or limited surgical management, full recovery should be expected. This is a report of two cases of this "benign variant" of high pressure water injection injury that resulted in toe amputations.

A theoretical model for carbon dioxide (CO2) migration in tilted aquifers with groundwater flow is presented to evaluate the injection of CO2 into a geological formation. Capillary force in the flow of two immiscible fluids in a porous medium creates a saturation transition zone, where the saturation changes gradually. A vertical equilibrium assumption is employed to solve for the capillary pre...

In this study we investigated the effects of the injection into the supraoptic nucleus (SON) of non-peptide AT1- and AT2-angiotensin II (ANG II) receptor antagonists, DuP753 and PD123319, as well as of the arginine-vasopressin (AVP) receptor antagonist d(CH2)5-Tyr(Me)-AVP, on water and 3% NaCl intake induced by the injection of ANG II into the medial septal area (MSA). The effects on water or 3...

We use a three-dimensional mixed-wet random network model representing Berea sandstone to compute displacement paths and relative permeabilities for water alternating gas (WAG) flooding. First we reproduce cycles of water and gas injection observed in previously published experimental studies. We predict the measured oil, water and gas relative permeabilities accurately. We discuss the hysteres...

Background and Aim: Water sorption is one of the most important properties that affects the quality of a prosthesis, and subsequently, the quality of treatment, and pa-tient’s quality of life. The aim of this study was to determine and compare the water sorption of two types of poly methyl methacrylate (PMMA) using the injection-molding systems with a traditional acrylic resin base material. M...
