Predicting dewatering equipment performance from laboratory tests
… simulate dewatering in a full-scale screw press. Tests were conducted to determine the effect of pressure and shear on dewatering of anaerobically digested, alum, waste activated, and pulp and paper sludges. The first part of the study involved tests conducted on a bench-scale belt filter press. …

Anomaly detection in laboratory tests subject to gatekeeping in selected health facilities
… organisations across the world. In South Africa, laboratory tests administered by government facilities are delivered by the National Health Laboratory Service (NHLS) regardless of payment, and hence there is a possibility that certain tests are over ordered by doctors at government health …

Field and Laboratory Tests of a Proposed Bridge Deck Panel Fabricated from Pultruded Fiber-Reinforced Polymer Components
… polyester matrix. When subjected to two strength tests, the first deck panel exhibited a safety factor with respect to legal truck loads of greater than 10. The second deck was subjected to AASHTO design loads, and under a simulated HS-25 axle plus impact the deck exhibited a maximum deflection of …

Laboratory Tests of a Bridge Deck Prototype With Glass Fiber Reinforced Polymer Bars as the Top Mat of Reinforcement
… the top mat of reinforcement. The purpose of the tests was to verify that the design would resist the loads for which it was designed and provide assurance that the deck would not unexpectedly fail due to the use of this new material. Behavior of the bridge and deck, such as failure load, failure …

Benthic Macroinvertebrate Susceptibility to Trout Farm Effluents
… were examined using multiple approaches. Static laboratory tests with the amphipod, Hyallela azteca, were conducted with exposures to water taken from a spring, effluent above a sedimentation basin, and effluent below a sedimentation basin. On-site mesocosms were constructed to expose previously …
