With increased application of co-solvent flushing technologies for removal of nonaqueous phase liquids from groundwater aquifers, concern over the effects of the solvent on native microorganisms and their ability to degrade residual contaminant has also arisen. This study assessed the impact of ethanol flushing on the numbers and activity potentials of trichloroethylene (TCE)-degrading microbia...

BACKGROUND Previous studies have reported the occurrence of taste and odour disturbances among patients undergoing IV flush with prefilled syringes of 0.9% sodium chloride (normal saline [NS]). These disturbances have been attributed to the leaching of volatile substances into the NS from the plastic of the syringe. To date, there have been no studies comparing the occurrence of taste and odour...

Flushing and locking of intravenous catheters are thought to be essential in the prevention of occlusion. The clinical sign of an occlusion is catheter malfunction and flushing is strongly recommended to ensure a well-functioning catheter. Therefore fluid dynamics, flushing techniques, and sufficient flushing volumes are important matters in adequate flushing in all catheter types. If a cathete...

BACKGROUND Non-touch fittings have been reported to be susceptible for Pseudomonas aeruginosa accumulation. A number of factors may contribute to this, including the frequency of usage, duration of water stagnation, or presence of plastic materials. Programmable non-touch fittings are appearing which allow regular automated post-flushing with cold water to prevent water stagnation. However, the...

BACKGROUND Persistent erythema and severe rosacea flushing can cause significant physical discomfort and emotional stress to patients. Currently, no satisfactory treatments are available. METHODS We report two cases of refractory flushing and erythema of rosacea that were successfully treated with intradermal botulinum toxin injections. RESULTS Good cosmetic results were achieved for both p...

To better understand carbon (C) cycling in arctic tundra we measured dissolved C production and export rates in mesocosms of three tundra vegetation types: tussock, inter-tussock and wet sedge. Three flushing frequencies were used to simulate storm events and determine potential mass export of dissolved C under increased soil water flow scenarios. Dissolved C production and export rates differe...

INTRODUCTION Dead space negatively influences carbon dioxide (CO(2)) elimination, particularly at high respiratory rates (RR) used at low tidal volume ventilation in acute respiratory distress syndrome (ARDS). Aspiration of dead space (ASPIDS), a known method for dead space reduction, comprises two mechanisms activated during late expiration: aspiration of gas from the tip of the tracheal tube ...

Ghezel sheep is one of the main breeds in the north-west of Iran which is reared for meat, milk and wool production. Improving reproduction of this breed will have a significant impact on the economic development of local farmers. Therefore, in the present study the effect of simultaneous use of estrus synchronization(controlled internal drug releasing (CIDR) and equine chorionic gonadotropin (...

This study aims at investigating the effectiveness of utilizing barley as a Flushing ration with an energizing source and soybean meal-based diets as a Flushing ration with a protein source the sexual and breeding behaviors in Ghezel sheep. To this end, 36 three and half-year old ewes (51±1.5 kilograms) with the record of giving birth to two lambs and 6 three-year old (89±2.5 kilograms) rams we...
