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...

From the rupture of Fundão dam in Mariana–MG, there are tailings still present at bottom plant that must be recovered. The flocculation followed by sedimentation operation can applied as a unit this recovering process. Instead using conventional inorganic coagulants, bio-based coagulants offer some advantages, due to their low toxicity and biodegradability. Nonetheless, use mining industry is n...

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...

Online trust is important in both business-to-business and business-to-consumer e-business. This paper focuses on the impact of trust in online retailing (e-tailing). Based on a review of selected studies, we articulate a conceptual framework of trust in e-tailing including its antecedents, and consequences, and propose some promising future research avenues in online trust. This paper will hel...

Although a growing body of research is developing to address the different e-business practices in the electronic marketplace, e-tailing strategies have only been investigated as part of the study of general e-business strategies. However, researchers recognise that innovative and unique modes of e-tailing operations have emerged in recent years. Therefore, this paper introduces an organising f...

Heavy metal pollutions of soil is one of the serious problems in the mining tailing areas, therefore, it is significant to estimate heavy metal of soil in the mining tailing areas. This research take Jinduicheng Mo mining tailings, Huaxian, Shaanxi Province as the study area. A total number of 288 soil samples collected at the mining tailing areas. And the heavy metal concentrations of Pb in so...

Iron ore tailings are mainly composed of SiO2 and iron, whose content determines the potential reuse strategy tailings. Compared with traditional wet chemistry approach, spectroscopy has proven its superior effectiveness in characterizing predicting minerals, such as iron oxides, clay, SiO2. This study aims to estimate TFe based on visible–near infrared (VIS–NIR, 350–2500 nm) thermal (TIR, 8–14...
