Laboratory investigation of capillary trapping under mixed-wet conditions
[1] Remaining oil saturation established by waterflooding was measured in Indiana limestone in its original, water-wet state and under mixed-wet conditions established by adding organic acid to the oil phase. The porous plate technique was used to establish initial oil saturations ranging from Snwi1⁄4 0.23 to 0.93 under capillary-dominated conditions. For water-wet conditions, the residual oil ...
متن کاملPerformance of breathing filters under wet conditions: a laboratory evaluation.
INTRODUCTION Heat and moisture exchangers in combination with a bacterial and viral filter (HMEF) are widely used during general anaesthesia. Excess patient secretions occluding the HMEF have been responsible for previous case reports of airway obstruction. A previous study suggested that differences in HMEF design might contribute to filter obstruction under wet conditions. METHODS We tested...
متن کاملA Laboratory Investigation of Acoustic Emissions Associated with the Brittle Fracture of Rock Under Dry and Wet Conditions
We have carried out a series of laboratory experiments on AE monitoring to investigate the fracture behaviour of some dry and water-saturated rock samples of south-east Gujarat and Maharashtra which have been experiencing prolific seismicity in recent years in India. The results obtained from the study of Pavgadh rhyolites and Godhra granites tested to failure under triaxial compression are pre...
متن کاملInvestigation of acute toxicity of lead-manganese mixture to fish under laboratory conditions
The aim of this study was to investigate acute toxicity (96-hr LC50 and lethal concentrations) of waterborne metal mixture (Pb+Mn) for the fish, Catla catla, Labeo rohita, Cirrhina mrigala, Ctenopharyngodon idella and Hypophthalmichthys molitrix. The extent of metals bio- accumulation in fish body organs viz. gills, liver, kidney, fins, bones, muscle and skin at both 96-hr LC50 and lethal conce...
متن کاملPredation in two species of leech under laboratory conditions
Two 60 day experiments on predation behavior of leeches were conducted concurrently. In the first, medicinal leeches, Hirudo orientalis (Utevsky and Trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?C and 23-24?C, containing starved Erpobdella octoculata (L.). At the high...
