Challenges for Resource Allocation, Decision Making and Consideration of Social Values for Screening, Diagnosis and Treatment of Hepatitis C in Canadian Populations
DownloadFall 2018
Introduction: Health care system decision makers face challenges in allocating resources for screening, diagnosis and therapies for hepatitis C, caused by the highly infectious and blood borne hepatitis C virus (HCV) (WHO, 2014). Approximately 240,000 individuals are infected with HCV in Canada...

Twenty-seven observation test pits were excavated at four different spoils dumps at three collieries in the Witbank Coalfield. The holes were dug into the upper three metres of the spoils to ascertain if any weathering profiles, variation with age or influence of topsoil covering could be gauged....

Chronic Fatigue Mechanisms in Autoimmune Diseases: Lessons from Primary Biliary Cholangitis and Systemic Sclerosis
DownloadFall 2023
Systemic sclerosis (SSc) is an autoimmune disease affecting the body's connective tissues, resulting in progressive fibrosis and vasculopathy. In some cases, individuals with SSc may also develop primary biliary cholangitis (PBC), another autoimmune disease characterized by damage to their...

Engineered soil covers are used for final closure options for both waste rock and tailings disposal facilities. Currently, cover construction requires excavation of appropriate cover material from a nearby site. If no suitable materials are available, the mine operation may have to ship...

Mining of sulfide-based ore deposits typically creates a potential for release sulfate and acid to groundwater, and many operating mines are thus predicted to require long-term post-closure treatment of groundwater. Toward the goal of selecting an optimal treatment, this paper compares costs of...

The design of soil covers as part of the remediation initiatives for mine waste facilities is common practice and more and more engineers are faced with designing these facilities. The design issues associated with these soil covers are complex and requires a good understanding of unsaturated...

The acid mine drainage (AMD) situation at three opencast collieries in the Witbank Coalfield, South Africa, was evaluated from different perspectives. Twenty-seven test pits were dug into the spoils of these collieries to characterise the in situ conditions of spoils of varying age. Detailed...

Four siltite-argillite rock samples were characterised (particle size, chemistry, mineralogy) and subjected to laboratory dissolution testing for 36 to 298 weeks. In two samples sulfur (0.99, 1.69 wt per cent) occurred largely as pyrite, and in the other two samples sulfur (0.96, 1.93 wt per...

The study focuses on sulfide oxidation processes in unweathered pyrite-rich mine tailings from a soil-covered impoundment in northern Sweden. To simulate the oxygen-limited conditions in water saturated tailings two long-term column experiments were performed. Results are presented for the first...

The co-mixing of tailings and waste rock involves the intimate blending of tailings and waste rock to create a new material (Co-Mix) with superior physical and hydraulic properties. The new material has a low hydraulic conductivity, low compressibility, high water retaining capacity and high...
