Abstract In the framework of development SWGO experiment, we have performed a detailed study single unit an extensive air shower observatory based on array water Cherenkov detectors. Indeed, one possible detector configurations for consists tanks, and to reach high detection efficiency discrimination capability between gamma-ray hadronic showers, different tank designs are under investigation. ...

Neutron diffraction analysis was employed to measure residual stresses near welds in used anhydrous ammonia nurse tanks. Tensile residual stresses contribute to stress corrosion cracking of nurse tanks, which can cause tanks to release toxic ammonia vapor. The analysis showed that tensile residual stresses were present in the tanks measured, and the magnitudes of these stresses approached the y...

Concrete naturally contains a large number of circular-like stochastic pores which weaken the tensile strength concrete and change crack propagation path. This study investigates influences size distribution spatial on fracture behavior based splitting test. The mesoscale model containing coarse aggregate, mortar, interface transition zone (ITZ), circular is established to simulate initiation, ...

Settling-thickening tanks are used to achieve separation of the liquid and solid fractions of faecal sludge (FS). They were fi rst developed for primary wastewater treatment, and for clarifi cation following secondary wastewater treatment, and it is the same mechanism for solids-liquid separation as that employed in septic tanks. Settling-thickening tanks for FS treatment are rectangular tanks,...

The primary mission of Oak Ridge National Laboratory (ORNLj during World War I1 was the processing of pure plutonium metal in support of the Manhattan Project. By-products of this process include radioactive cesium-1 37 and strontium-90. Between 1943 and 1951, the Gunite and Associated Tanks (GAAT) at ORNL were built to collect, neutralize, and store these byproducts. Currently, twelve gunite t...

As a paradigm for heat conduction in 1 dimension, we propose a class of models represented by chains of identical cells, each one of which containing an energy storage device called a “tank”. Energy exchange among tanks is mediated by tracer particles, which are injected at characteristic temperatures and rates from heat baths at the two ends of the chain. For stochastic and Hamiltonian models ...

Increasingly, space for remanufacturing is seen as the most valuable resource to achieve circular economy (CE) policy goals, in particular cities. However, many cities, industrial urban areas are increasingly subject of – mostly designed - residential redevelopment. The proposition this paper that these diminishing host, at least potentially, essential functions necessary “close material loop.”...
