Fathollahzadeh, Karo. "Long-term Open-pit Mine Production Scheduling with Grade Engineering." Thesis, Curtin University, 2022. http://hdl.handle.net/20.500.11937/89233.

Full text

Abstract:

Open pit mine production scheduling is a strategic decision-making problem that plays an important role in surface mining, as the economic viability of a mining project is highly dependent on careful long-term planning. An open pit mine production schedule seeks to determine the optimal sequence for a mineral deposit and the flow of materials within a mineral value chain (i.e., stockpiles, waste dumps and processing streams). This thesis investigates open pit mine production scheduling with the incorporation of Grade Engineering. The Grade Engineering concept was introduced by the Cooperative

Abstract:

The purpose of this study was to explore and analyze which fifth-grade teacher inputs were the most important predictors of future outcomes of eighth-grade math students. This quantitative study looked at mathematical achievement through the lens of an education production function. The three inputs that were analyzed were fifth-grade teachers’ background; perception of professional development; and instructional practices and the relationship of those practices to achievement in eighth-grade math. In order to find the relationship between the above variables and student achievement, descripti

Orholor, Ayomanor Benedict. "The production of low-cost solar grade silicon from rice husk." Thesis, Sheffield Hallam University, 2017. http://shura.shu.ac.uk/23502/.

Abstract:

Rice husk, an agricultural waste product obtained in large quantities in many countries including Nigeria, is very rich in siliceous materials. It has been known for several decades that, with careful processing, rice husk can be a source of metallurgical grade silicon. In Nigeria this would have the benefit of transforming large volumes (> 600,000 tonnes per annum) of agricultural waste into a partial solution to that country's issue with energy distribution. In this work, silica of between 95.24% and 98.03% purity has been prepared from RHA (ashed at 700°C, 800°C, 900°C and 1000°C for either

Abstract:

Canada accounts for 15% of the world’s uranium production (World Nuclear Association). The Athabasca Basin in northern Saskatchewan Canada contains a number of high grade, uranium ore deposits which occur at, or immediately below, an unconformity between Archean and Paleoproterozoic metasediments and intrusive rocks and overlying Proterozoic sandstones. The uranium ores are largely composed of high concentrations of uraninite and Pitchblende with naturally occurring 238U/235U ratios. U- 236 (half-life of 23.42 Myr) will be produced when 235U absorbs a neutron and the nucleus does not fission.

Abstract:

Hardwood sawmills must become more efficient to remain competitive. One way to increase efficiency and competitiveness is to increase the value or lumber volume produced from logs. While methods to maximize value and volume recovery exist for round logs, little information exists on how to maximize these outcomes for logs with ellipticality. The goal of this research was to determine the impact of low and high degrees of ellipticality on green lumber grade and volume recovery for red oak logs under current sawing methods. Logs of low and high ellipticality were selected and processed at four A

Engaging young children to partake in creative arts activities is often viewed as inferior to most academic subjects by some teachers and parents.

Abstract:

Speaking a foreign language is a major part of communicating in that language. Since LGY 69, spoken English has received the same attention in teaching as the writing of English; and in the national tests today spoken English is considered 1/5 of the test grade. However, students in many cases find it more difficult to speak English than to write it and some teachers still focus more on writing and grammar than on speaking. In this essay, I am trying to show how a group of fairly fluent students tackle the oral part of their national test and what strategies they use to overcome linguistic di

Abstract:

Several recent studies have shown that acid mine drainage (AMD) may be a promising source of rare earth elements (REEs), which are essential feedstocks for many high tech applications and defense products. AMD is a longstanding environmental challenge and is currently the primary pollutant of water in the Appalachian coal mining region. Acid generated during the coal mining process tends to leach several transition metals from the surrounding rock strata. While iron, aluminum, and manganese have traditionally been noted as the predominant metals in AMD, recent studies have also shown that REEs

Abstract:

Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para obtenção do grau de Mestre em Engenharia Mecânica<br>An investigation was carried out to evaluate the potential application of Friction Stir Processing (FSP) to produce Functionally Graded Materials (FGM‟s). Friction stir processed materials can be considered as FGM‟s since the localized microstructural modification results in a gradual property modification. Therefore, to enhance hardness and ductility at specific superficial levels, surface layers of processed material were produced by multiple

Abstract:

L'étude des partis et de la politique de défense au Royaume-Uni a soulevé des interrogations multiples sur le fonctionnement du système parlementaire britannique dans le contexte spécifique de la défense. En nous concentrant sur la contribution des partis conservateur et travailliste à la production de la politique publique de défense depuis 1945, nous avons pu distinguer les principales caractéristiques du processus décisionnel britannique aussi bien en temps de paix, qu'en temps de crise et de guerre. A partir d'un survol de la politique de défense depuis 1945, sont apparus des problèmes fon

Abstract:

Esta tese teve como objetivo apresentar quais os elementos que devem constar em um modelo descritivo para representar o que ocorre na realidade na governança em clusters. Para atingir este objetivo desenvolveu-se uma pesquisa para compreender que elementos eram considerados por pesquisadores ao escreveram sobre a governança de aglomerados produtivos. De posse destes dados, o material resultante foi classificado considerando sua natureza. Se descritivos ou normativos. Assim foram constituídos os Elementos da Governança em Cluster com sua conceituação a partir do que indica a literatura da área.

La quitina es el segundo polisacárido en abundancia en la naturaleza y a partir de ella se obtiene la quitosana, un polielectrolito catiónico cuando se disuelve en soluciones acuosas ácidas que es biodegradable, biocompatible, bacteriostático, antifúngico y tiene la capacidad para formar películas, fibras y matrices porosas ligeras. Así, la quitosana es un polímero natural interesante para aplicaciones en medicina, farmacia, alimentos, cosmética, agricultura, tratamiento de aguas, etc. La quitina se transforma en quitosana por medio de la desacetilación.

Abstract:

Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components. Compared to conventional machining, EBM offers enhanced efficiency for production of customized and patient specific parts such as e.g. dental prosthetics. However, dental prosthetics are challenging to produce by EBM, as their sm
