the electro-osmotic consolidation is a method to improve geotechnical properties of soft clayey soils. the feasibility of electro–osmotically induced consolidation can be examined through the soil coefficient of electro–osmotic permeability (ke) and the electro–osmotic coefficient of water transport (ki). using an electro-osmotic testing cell, ke and ki parameters were measured in urmia lake we...

BACKGROUND Capsule retention in the small bowel is a known complication of small-bowel video capsule endoscopy. Surgery is the most frequently used method of capsule retrieval. OBJECTIVE To determine the incidence and causes of capsule retention and to describe double-balloon endoscopy (DBE) as the primary technique used for capsule retrieval. DESIGN Retrospective analysis of all video caps...

the aim of the current study was to design a porous osmotic pump–based drug delivery system for controlling the release of buspirone from the delivery system. the osmotic pump was successfully developed using symmetric membrane coating. the core of the tablets was prepared by direct compression technique and coated using dip-coating technique. drug release from the osmotic system was studied us...

among the most common types of problematic soils, are probably the expansive ones. one of the modern methods of strengthening and improving the soil in place is the use of electro-osmotic improving treatment. this paper presents the design of an apparatus suitable for electro-osmotic treatment. a soil sample of a high expansive potential was compacted and the effect of electro-osmotic treatment...

UNLABELLED Aim. To evaluate capsule endoscopy in terms of incomplete examinations and capsule retentions and to find risk factors for these events. Material and Methods. This retrospective and consecutive study includes data from 2300 capsule enteroscopy examinations, performed at four different hospitals in Stockholm, Sweden from 2003 to 2009. Results. The frequency of incomplete examinations ...

a capsule endoscope with use of a transparent hood and real-time viewer Capsule endoscopy relies on an intact swallowing mechanism and unimpeded passage of the capsule through the pylorus [1]. A new method for endoscopic placement of the capsule is described. A transparent hood (MH-464; Olympus, Tokyo, Japan), whose inside wall is lined with vinyl tape, is attached to the tip of the endoscope (...

abstract: the combination of pulsed vacuum osmotic dehydration and microwave drying of garlic bulbs were examined. the response surface methodology (rsm) was used to determine the effect of nacl concentration (8%-20%), osmotic solution temperature (25-65°c), operation pressure (240-830 mbar), immersion time (20-300 min) and microwave power level (100-600 w) on water loss (wl), solids gain (sg),...

in order to study of hydropriming and halopriming on germination and early growth stage of wheat (triticum aestivum l.) an experiment was carried out in laboratory of the department of agronomy and plant breeding, shahrood university of technology. seed treatments consisted of t1: control (untreated seeds), t2: soaking in distilled water for 18 h (hydropriming). t3: soaking in -1.2 mpa solution...

The pharmacological activity of herbal medicine is an overall action of each component in accordance with their original proportion. An efficient, sustained, and controlled-release drug delivery system of herbal medicine should ensure the synchronized drug release of each active component during the entire release procedure. In this study, silymarin (SM), a poorly soluble herbal medicine, was s...

Low-pressure osmotic-based membrane separation, such as osmotic distillation (OMD) and forward osmosis (FO), is a separation process suitable for the concentration of liquid food with heat-sensitive components. In FO, dense hydrophilic used osmotic-pressure gradient driving force. Reverse salt diffusion low are major phenomena impeding FO application. Food preservatives can be applied draw solu...
