In matrix acidizing operations, the main goal is increasing permeability. For production engineers, it is desirable that acid could be injected into whole [M.N.1] [amehri.gh2] pay zone. Sometimes, this pay zone has a long height and various sub-layers which have different permeability values. To prevent acid from going completely into the most permeable sub-layer, one of the useful techniques i...

Previous studies have shown that seawater may alter the wettability in the direction of more water-wet conditions in carbonate reservoirs. The reason for this is that ions from the salt (sulphat, magnesium, calsium, etc) can create a wettability alteration toward more water-wet conditions as salt is absorbed on the rock. In order to initiate a more systematic study of this phenomenon a 1-D math...

BACKGROUND High-frequency B scan ultrasonography is a proven method for the assessment of anterior segment diseases. Only few studies have used sonography to examine the lacrimal drainage system. We examined the proximal lacrimal drainage system by high-resolution 20-MHz ultrasound to verify the possibility to identify intracanalicular lacrimal plugs. METHODS Eight patients who had received 1...

PURPOSE Long-term closure rates of anorectal fistulas using fibrin glue have been disappointing, possibly because of the liquid consistency of the glue. A suturable bioprosthetic plug (Surgisis, Cook Surgical, Inc.) was fashioned to close the primary opening of fistula tracts. A prospective cohort study was performed to compare fibrin glue vs. the anal fistula plug. METHODS Patients with high...

We describe the smart plug with a wireless sensor network for monitoring of electrical usage in smart house. The smart plug integrates an AC power socket, a relay to switch the socket ON/OFF, a current transformer sensor to sense current of load appliance and a Kmote. The Kmote is a wireless communication interface based on TinyOS. We evaluated smart plug in a laboratory, analyzed and presented...
