This study investigates the contribution of several marinas to fecal indicator bacteria impairment in Newport Bay, a regionally important tidal embayment in southern California. Three different fecal indicator bacteria groups were assayed, including total coliform, Escherichia coli, and enterococci bacteria, all measured using the IDEXX Colilert and Enterolert system. To document temporal varia...

Drains are a common feature of the post-operative management of surgical patients. While drains serve an important function they are also associated with complications such as haemorrhage, tissue inflammation, retrograde bacterial migration and drain entrapment. It is therefore essential that nurses are familiar with the monitoring and management of surgical drains, but also the process involve...

The authors report a simple technique for effective management of surgical drains and their reliable removal in elective hip and knee arthroplasty. Many surgeons use surgical drains for elective total hip and knee arthroplasties and instruct residents in their use despite limited evidence to support routine use of surgical drains in noninfected cases. There are many different types of drains an...

One of the main concerns to design earth dam is the stability of the upstream slope of the earth dam in phase of rapid drawdown. Confined pore water pressure reduces the effective stress in this mode, so possibility of the instability and slippage will be increased. The main goal of this research is to investigate changes in the pore water pressure by using horizontal drains in upstream slope o...

BACKGROUND Problems in the management of thoracic trauma have stimulated the search for an alternative to underwater seals for drainage of the pleural cavity. A chest drainage bag incorporating a one way flutter valve has been compared with underwater seal drains in a randomised clinical trial. METHODS During June-December 1989 119 patients undergoing elective thoracotomy were randomised to r...

OBJECTIVE Drains and catheters are used for both prophylactic and therapeutic reasons in clinical practice. This study aimed to investigate the factors that affect safety of drains, catheters, nasogastric tube and central venous line in patients who underwent surgery. MATERIAL AND METHODS Two hundred and four consecutive patients who were operated at the general surgery clinics under general ...

BACKGROUND Cervical drains have historically been used to avoid postoperative wound and respiratory complications such as excessive edema, hematoma, infection, re-intubation, delayed extubation, or respiratory distress. Recently, some surgeons have ceased using drains because they may prolong hospital stay, operative time, or patient discomfort. The objective of this retrospective case-control ...

Tile drained land with phosphorus (P)-rich topsoil is prone to P loss, which can impair surface water quality via eutrophication. We used by-products from steel and energy industries to mitigate P loss from tile drains. For each by-product, P sorption maximum (P(max)) and strength (k) were determined, while a fluvarium trial assessed P uptake with flow rate. Although two ash materials (fly ash ...
