Mining activities generate residues during the ore concentration process. These wastes are placed into large tailing storage facilities, and upon mine closure, these tailings must be reclaimed. This study aimed to determine how different reclamation methods, involving combinations of planted boreal woody species organic amendments application (paper mill sludge biosolids, chicken manure, topsoi...

The paper derives the value of a storage facility that is too small to affect an exogenously defined price process of a storable good with seasonal and mean-reverting components. It provides an elegant new continuous-time model of storage under simple assumptions, which could be applied, for example, to natural gas. In the case without a seasonal component, closed form solutions are obtained as...

underground caverns in rock salt deposits are the most secure disposal method and a type of gas-storing facility. gas storage plays a vital role in ensuring that a strategic relationship is secured between an established energy infrastructure provider and a midstream energy company. the fischells brook area is a pillow-shaped body of salts located in the st. george's bay area of southwest newfo...

The PANDA experiment is one of the large installations at the future international Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It will be located at an internal target station of the High Energy Storage Ring for anti-protons. The PANDA physics programme focusses on charmonium spectroscopy and the search for glueballs and hybrids, but also includes hypernuclear physics...

To obtain a better understanding of metabolically active microbial communities, we tested a molecular ecological approach using poly(A) tailing of environmental 16S rRNA, followed by full-length complementary DNA (cDNA) synthesis and sequencing to eliminate potential biases caused by mismatching of polymerase chain reaction (PCR) primer sequences. The RNA pool tested was extracted from marine s...

This study investigates the mechanisms underlying the deviation from Chick-Watson kinetics, namely a tailing curve, during the disinfection of viruses by chlorine dioxide (ClO2). Tailing has been previously reported, but is typically attributed to the decay in disinfectant concentration. Herein, it is shown that tailing occurs even at constant ClO2 concentrations. Four working hypothesis to exp...

Tracer and indicator microbe runoff experiments were conducted to investigate the influence of solution chemistry on the transport, retention, and release of Escherichia coli D21g. Experiments were conducted in a chamber (2.25 m long, 0.15 m wide, and 0.16 m high) packed with ultrapure quartz sand (to a depth of 0.10 m) that was placed on a metal frame at slopes of 5.6%, 8.6%, or 11.8%. Runoff ...

Abstract Reliable assessment of earthen dams’ stability and tailing storage facilities widely used in the mining industry is challenging, particularly under seismic load conditions. In this paper, we propose to take into account effect dominant frequency on tailing/earthen dams. The calculations are performed by finite element modelling (FEM) with Mohr–Coulomb failure criteria. To separate cont...

PURPOSE Energy-resolved CT has the potential to improve the contrast-to-noise ratio (CNR) through optimal weighting of photons detected in energy bins. In general, optimal weighting gives higher weight to the lower energy photons that contain the most contrast information. However, low-energy photons are generally most corrupted by scatter and spectrum tailing, an effect caused by the limited e...
