local scouring around bridge piers is a natural phenomenon caused by the erosive process of flowing stream on alluvial beds. the 3d flow field around bridge piers interacting with the bed materials increases complexity of local scour process. the local scour depth develops in accelerated flows and if it is not predicted correctly, the bottom level of local scour hole will exceed the original le...

abstract background: the loop colostomy is one of the most popular techniques used as a protective maneuver for a distal anastomosis and/or temporary fecal diversion. we are introducing the use of a full thickness skin bridge under the large bowel instead of a glass rod which alleviates problems such as protrusion of the large bowel, retraction of the bowel into the abdomen after removing the r...

Taguchi L9 orthogonal array was implemented to select optimum values of process parameters and to attain the maximum removal of pollutants and power generation from dairy industry wastewater using double chambered salt bridge microbial fuel cell. The maximum chemical oxygen demand reduction, current, voltage, power, current density and power density in double chambered salt bridge microbial fue...

Sonic Echo (SE) testing method is a well-known, versatile method to gather information pertaining to unknown bridge foundations. Many studies on the applicability and methodology improvement of SE tests to evaluate individual piles and foundations supporting the superstructure have been reported previously. However, there is a rare opportunity for obtaining the performance of SE tests without t...

this article presents the seismic vulnerability assessment of the s. joão de loure bridge, inportugal. the single span steel bridge has riveted joints, commonly affected by corrosion,which can lead to a significant stiffness reduction. with the objective of evaluating theinfluence of the joints stiffness in the structural response of the bridge, a structural model ofthe bridge was created, and ...
