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...

The accurate selection of a processing plant site can result in decreasing total mining cost. This problem can be solved by multi-criteria decision-making (MCDM) methods. This research introduces a new approach by integrating fuzzy AHP and gray MCDM methods to solve all decision-making problems. The approach is applied in the case of a copper mine area. The critical criteria are considered adja...

Annals of Reviews & Research open access journal that publishes high-quality solicited and unsolicited articles, from various types subject areas ranging management to engineering sciences, accounting, criminal etc. which deal with innovative research work.

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...

Innovative and sustainable technologies are being developed to meet the demand for critical economically important metals minimize valorize increasing quantities of industrial waste streams. This study investigates a valorization route recovery copper from sulfide tailing (0.4 wt % Cu). Microwave-assisted roasting was used transform sulfidic fraction into sulfate fraction, which increased solub...

This study, carried out in tailings from two sediment-hosted stratiform copper deposits the Lublin-Głogów Copper District Poland (Kupferschiefer-type deposit) and Zhezkazgan (cupriferous sandstone-type Kazakhstan, analysed mineralogy of copper, zinc, lead minerals as related to metal accumulation sediments. Microscopic study reflected light SEM–EDS (Scanning Electron Microscope—Energy Dispersiv...
