Order-preserving encryption (OPE) and order-revealing encryption (ORE) are among the core ingredients for encrypted database (EDB) systems as secure cloud storage. In this work, we study the leakage of OPE and ORE and their forward security. We propose generic yet powerful file-injection attacks (FIAs) on OPE/ORE, aimed at the situations of possessing order by and range queries. The FIA schemes...

The other-race effect (ORE) in face recognition refers to better recognition memory for faces of one’s own race than faces of another race—a common phenomenon among individuals living in primarily mono-racial societies. In this article, we review findings suggesting that early visual and sociocultural experiences shape one’s processing of familiar and unfamiliar race classes and give rise to th...

Mining and quarrying waste is the second largest stream in Europe. Sulfidic ore processing residues (tailings) pose a large challenge, because they contain hazardous metal(loid)s can lead to acid mine drainage. However, tailings also valuable base, precious, critical metals, which be used different technological applications, as well silicates clay minerals that offer possibilities for use buil...

It is found that regions with depleted, or on the verge of depletion, mineral resources are subject to additional pressures due intensifying social and environmental problems. This paper proposes development mining industry, reducing dependence economy sharp volatility raw materials market in a period global shocks by addressing problems depleting resource base. assumed geotechnology from simpl...

3D geological modeling of lithogeochemical and geological data provides insight into the role of the sulfide ore horizon and associated footwall hydrothermal alteration in localizing shear strain in the Flin Flon volcanogenic massive sulfide deposits, Canada, as deformation evolved from brittle-ductile to ductile regimes during collisional stages of the 1.9–1.8 Ga Trans-Hudson orogeny. 3D spati...

Th is study aims at studying effect of anaerobic dissimilatory iron (III) reducing bacterial consortium on different phases of iron present in lateritic n ickel ore. Such conversion in lateritic nickel ore are helpful in better recovery of sorbed metal values like Ni and Co by subsequent bioleaching or acid leaching. Here properties of thermally and microbially reduced lateritic nickel ore are ...

In order to provide a technical basis for the subsequent concentration and utilization of tailings treatment process in an iron ore mine, achieve objectives cost reduction sustainable development, settling capacity slurry with initial 40% its natural state were tested conjunction pumping supply index beneficiation metal mine. The test results show that particles settle at overall fast rate: bas...

Conventional gravity separation process of iron mineral fines is not very effective. In present work Multi Gravity Separation (MGS) process has been studied. This study was performed on a low-grade iron ore namely goethiticlateritic ore (GLO) from Eastern India. Detailed mineralogical, physical and chemical characteristics of a goethiticlateritic iron ore showed that the sample contained porous...
