Open-pit mine planning with operational constraints
Open-pit mines must be designed to develop the Earth’s natural resources in the most responsible, sustainable, and economic way. Traditional mine planning optimization methods do not consider operational constraints; such as minimum mining width or minimum pushback width constraints, and often do …

Investigation of a clay lined storage pit
… work. Objectives included delineating the pit geometry and liner system, assessing the characteristics of the natural soils at the site as well as the wastes, and evaluating the degree of contamination of the natural subsoils around the pit. The field investigation findings show a more …

Pit House Revival: An Exercise in Composition
Composition is an approach to "art through structure" (Dow, 1997). Following Arthur Wesley Dow's work, Composition 1997, this thesis consists of a series of photographic and architectural exercises, demonstrating each of Dow's elements and principles of composition. Though Dow does not define his …

Physiological studies of bitter pit in apple
… histology and physiology of the disorder bitter pit in apple (Malus domestica Borkh.) were studied. A two year field study was conducted to induce consistent bitter pit development in type ’Delicious’ (D) and ’Golden Delicious’ (GD) apple fruit. Multiple spray treatments of CaCl₂ and MgCl₂, …

Long-term open-pit planning by ant colony optimization
… of long-term planning of a hard rock open pit mine (discontinuous exploitation operation) is a large combinatorial problem which cannot be solved in a reasonable amount of time through mathematical programming models because of its large size. In this thesis, a new metaheuristic algorithm …

Into the snake pit: Heliodorus's Aethiopica and cognitive pluralism
This PhD thesis explores the conflicting narratological momenta at play in Heliodorus’s Aethiopica (approx. fourth century C.E.) and their relationship to the novel’s irreconcilable ideological impulses. The conception of this novel as a whole is still dominated by the readings of Jack Winkler and …

Triggering Mechanisms and Stabilization of a Massive Pit Slope Failure
The 2013 Bingham Canyon slope failure was probably the largest non-volcanic landslide in NorthAmerican history. Because it took place in an active mine with substantial monitoring systemsalready in place, its geological setting and progress to failure are better understood than mostlandslides. The …

Flexural Strength of a Pit and Fissure Sealant Containing Microcapsules
… microcapsules have on the flexural strength of pit and fissure sealant formulations. Pit and fissure sealants that contained microcapsules were incorporated into formulations at 5 w/w% of microcapsules (2 w/w% of 5.0 M Ca(NO3)2; 2 w/w% of 0.8 M NaF; 1 w/w% of 3.0 M K2HPO4) were added to pit and …

Potential groundwater contamination from pit latrines in Ga-Maja and Reefentse
Pit latrines are one of the most common methods of human excreta removal in low-income countries. Groundwater is a critical water resource in many peri-urban areas where there is no municipal water supply. Groundwater resources are commonly vulnerable to pollution from on-site sanitation practises, …

Pit initiation on passivated metal surfaces: crystallographic orientation and environmental effects
The susceptibility to pitting corrosion of tin and zinc was found to be dependent on the crystallographic orientation of the surface in chloride solutions. For tin single crystals, the(111) face showed the lowest critical pitting potential among five differently oriented surfaces. The critical …
