Abstract: In recent years the application of partial nitrification techniques has been denoted as very promising. These methods are based on the oxidation of ammonia to nitrite and the inhibition of the nitratation using different ...

Abstract: Tribocharged electrostatic beneficiation of a lunar simulant and actual Apollo regolith has been shown to be successful under a high lunar vacuum in which various degrees of efficient particle separation and mineral ...

Abstract: We captured interesting static and dynamic behavior of the liquidvapor interface in welldefined silicon micropillar arrays during thermally driven evaporation of water from the microstructured surface. The 3D shape of the ...

Abstract: The bridge inspection process has multiple steps. One obvious element is for inspectors to identify defects in the main components of the structural system and assign condition ratings. These condition ratings are somewhat ...

Abstract: A photobioreactor (PBR) for microalgae culture is a highly efficient system for biomass production. In the present study, the performance of an airlift (ALR) (with a centrictube column) and a bubble column (BC) photobioreactors ...

Abstract: The concept of living off the land by using the indigenous resources of the Moon, Mars, or other potential sites of robotic and human exploration has been termed in situ resource utilization (ISRU) and will be an enabling ...

Abstract: This paper analyzed the eco-efficiency of concretes (water/cement ratio = 0.50; cement content=350  kg/m3, and slump = 7 cm) with blended cement containing 25% by weight calcined pozzolan obtained from a low-grade ...

Abstract: Inadequate signage and pavement markings and driver distractions in roadway work zones are contributory high-risk factors for workers and drivers on two-lane rural and multilane freeway facilities. The changes imposed by ...
