BJS (British Journal of Surgery), EarlyView., 2020 Clean Cut is a multimodal, adaptive, checklist‐based infection prevention programme designed to improve compliance with six critical perioperative infection prevention practices. After introducing the programme at five hospitals in Ethiopia, compliance with critical infection prevention standards significantly improved and the relative risk of ...

Numerical modelling of erosion and sedimentation around offshore pipelines [PDF]
, 1990 In this paper a numerical model is presented for the description of the erosion and sedimentation near pipelines on the sea bottom. The model is based on the Navier-Stokes equations and the equation of motion and continuity of sediment.\ud \ud The ...

Using side flow jets as a scour countermeasure downstream of a sluice gate
Beni-Suef University Journal of Basic and Applied Sciences, 2021 Background Local scour is one of the main problems affecting the stability and operation of control hydraulic structures. Many techniques were used to control the resulting scour.

A local scour prediction method for pile caps in complex piers [PDF]
, 2011 The outcomes of an experimental study on local scour at a pile cap are presented. Experiments were conducted with the approaching flow having an undisturbed flow depth and a threshold flow velocity.

Physical Modeling of Local Scouring around Bridge Piers in Erodable Bed
Journal of King Saud University: Engineering Sciences, 2007 The construction of bridges in alluvial channels will cause a contraction in the waterway at the bridge site. The contraction in the waterway will cause a significant scour at that site.

Numerical Simulation on the Local Scour Processing and Influencing Factors of Submarine Pipeline
Journal of Marine Science and Engineering, 2023 To investigate the different influencing characteristics of local scour around submarine pipelines, hydrodynamic and sediment transport two-dimensional models based on Flow-3D are used to numerically simulate the local scour around the pipeline under ...

Local Scour Near Flexible Flow Deflectors [PDF]
Water, 2020 Rigid flow deflectors are usually used on water flow beds to protect engineering structures such as breakwater in coasts and to regulate flow routes in open channels. To reduce its side-effects, i.e., local scour at the toe of deflectors, a flexible flow deflector is proposed, and the corresponding local scour was investigated in this study.

Validation of some bridge pier scour formulae using field and laboratory data [PDF]
, 2005 Estimation of maximum local scour depth at the bride pier site is necessary for the safety and economy of the designed bridge. Numerous formulae are available and almost all of these formulae were developed based on laboratory data.

Local scour around a bridge pier under ice-jammed flow condition – an experimental study
Journal of Hydrology and Hydromechanics, 2021 The appearance of an ice jam in a river crucially distorts local hydrodynamic conditions including water level, flow velocity, riverbed form and local scour processes.
