Heap leaching of refractory gold ore by integrating enhanced bio-oxidation of pyrite and chloride-based gold leaching

Gold occurs in association with pyrite and arsenopyrite in the Carlin-type gold deposit, with little gold being contained in carbonaceous materials. Extracting this gold requires pretreatment, such as pressure oxidation or roasting, to remove carbonaceous materials and sulphides, followed by the application of alkali cyanide or thiosulphate solution to leach gold. These processes are energy-intensive […]

Investigations in real-time spinal magnetometry using magnetoencephalography (MEG) for therapeutic biofeedback

Oscillatory neuronal activity can be quantified to help diagnose states of health and disease in the brain. These activities change on a fast time scale of milliseconds, which can only be captured by direct measurement of the brain’s electromagnetic activity. This is accomplished utilizing MEG and EEG technology, which can measure non-invasively these fast changes […]

Using Engaged Philosophical Inquiry in Drug Education – Year Two

Research has shown that “no use” drug education programs, with the objective of scaring or shaming youth into abstinence, have not been effective in addressing problematic substance use. The ineffectiveness of such scare tactic approaches has led program developers to focus on prevention and harm reduction associated with drug use, or in general, health literacy […]

Designing a Usable Software Lifecycle Traceability Language Part 2

Teams of specialized workers develop most software. For example, one team may specialize in the requirements that describe what the software is to do. Another team may specialize in producing the software itself. Yet another team may specialize in determining whether the software meets the desired requirements. Supporting communication between all these teams is challenging: […]

Multi-dimensional and long-term reactive transport analysis of the geochemical stability of sedimentary basins

Sedimentary rock formations are currently under consideration for the placement and long-term storage of used nuclear fuel originating from nuclear power generation. A thorough understanding of the long-term geochemical stability in these rock formations is important to prove that future interactions of the waste material with aquifers as well as flora and fauna at the […]

Generating Insight for Continuing Care through Exploration of RAI-MDS Data with Data Analytics and Computational Mode

The Resident Assessment Instrument Minimum Data Set (RAI-MDS) is used by health authorities for collecting information about individuals in continuing care facilities. Collected quarterly, RAI-MDS records contain more than 500 data elements, including cognition, psychosocial well-being, health conditions, communication, physical function, and activity patterns. Because of this it has great potential for providing an incomparable […]
