RFID (Radio-Frequency IDentification) is a key emerging technology for supply-chain monitoring and detection of counterfeit and grey-market goods. The most prevalent RFID tags are, however, simply “wireless barcodes,” themselves vulnerable to cloning and counterfeiting. While continuous monitoring can, in principle, detect cloning attacks, real-world supply chains often contain significant blin...

Workability is a key performance criterion for mining cemented tailing backfill, which should be defined in terms of rheological parameters such as yield stress and plastic viscosity. Cemented tailing backfill is basically composed of mill tailings, Portland cement, or blended cement with supplementary cement material (fly ash and blast furnace slag) and water, among others, and it is important...

Changes in the tailing properties (increasing clay mineral content and fine particles) and poor operation of the dewatering systems have negative impacts on the Tailing Storage Facilities (TSF) of the Shahrbabak copper complex. The design solid concentration of the thickened tailings is 63 wt.% in the Shahrbabak paste plant but it is well below the design value right now (approx. 55 wt.%). The ...

The inevitable depletion of mineral resources, the constant deterioration of the geological and mining conditions for the development of mineral deposits and the restoration of raw materials from mining waste by recycling are all urgent problems we face today. The solution to this problem may ensure: a considerable extension of raw material source; decrease of investments in opening new deposit...

Immunocytochemical localization of DAMP, a reagent used to detect low pH intracellular compartments, was studied in cultured neurons from rat hippocampus and in frog retinas. We find that DAMP is more sharply localized and that the immunocytochemical reaction is stronger when horseradish peroxidase or other proteins are included in the medium used to administer DAMP to the cells. A likely expla...

This paper may be of particular interest to the readers as it provides a new environmental risk assessment system for phosphogypsum tailing dams. In this paper, we studied the phosphogypsum tailing dams which include characteristics of the pollution source, environmental risk characteristics and evaluation requirements to identify the applicable environmental risk assessment methods. Two analyt...

E-tailing websites are often perceived to be static, impersonal and distant. However, with the movement of the World Wide Web to Web 2.0 in recent years, these online websites have been found to display personalities akin to ‘humanistic’ qualities and project impressions much like its retailing counterpart i.e. salespeople. This paper examines the personality of e-tailing websites and their imp...

First, concentrating on the seasonal (s = 52) lags, the ACF shows a strong peak at h = 1s and lesser, but still statistically significant peaks at h = 3s , 4s, 5s, and 7s. The PACF shows statistically significant peaks at only h = 1s. It appears that: • the ACF is cutting off after lag 1s and the PACF is tailing off in the seasonal lags • the ACF is cutting off after lags 3s, 4s, 5s, or 7s, and...

Cholesterol-rich regions are attractive targets for studying metabolic disorders that involve accumulation of cholesterol. Despite efforts to develop probes for labelling cholesterol-rich regions in cells, few of these reagents have a low molecular weight. Previous studies have shown that the acidotropic pH indicator, N-{3-[(2,4-dinitrophenyl)amino]propyl}-N-(3-aminopropyl)methylamine dihydroch...
