Abstract:

A significant component of recent space exploration has been unmanned mission to comets and asteroids. The increase in interest for these bodies necessitates an increase in demand for higher fidelity trajectory simulations in order to assure mission success. Most available methods for simulating trajectories about asymmetric bodies assume they are of uniform density. This thesis examines a hybrid method that merges a mass concentration ("mascon") model and a spherical harmonic model using the "Brillouin sphere" as the interface. This joint model will be used for simulating trajectories about v

Abstract:

A novel route to chiral and achiral 2-aryloxazolyl compounds, building upon work already extant in the group has allowed for the development of an alternative route to oxazoline ligands. This route allows for the previous ease of scalability and high yields whilst vastly reducing reaction times and improving the purification procedure. This new method is significantly gentler using ambient conditions throughout much of the procedure and is therefore synthetically much simpler. The total reaction time has also been reduced allowing for the production of cleaner materials, faster and in analogou

Abstract:

As climate change continues to drive glacier retreat in the Cordillera Blanca, Peru, the fraction of dry season runoff derived from groundwater baseflow is increasing. Therefore, it is necessary to improve our understanding of proglacial hydrogeology to forecast how groundwater can offset decreasing meltwater resources. Unfortunately, little is known about high-elevation groundwater, the physical hydrogeological properties of aquifers, or contributions to stream flows in the Cordillera Blanca, Peru. This thesis addresses these knowledge gaps and presents the results from a groundwater inves

Thesis (PhD)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: In many developing countries, rapid urbanisation continues to substantially transform land from agricultural and rural land uses, as well as natural landscapes into urban areas. This leads to significant changes to the socio-economic fabric and nature of the natural environment. Data to monitor such transformation is often out of date, unreliable, in unstandardised format, cumbersome and expensive to collect or simply unavailable in urban centres of many developing countries. These characteristics inhibit local authorities‘ and

Abstract:

An interview study was undertaken to explore Swedish broiler producers´ views for the potential of hops (H. lupulus L.) to reduce reliance on ionophorous coccidiostats in broiler production. The design was a mixed methodology between grounded theory and case study with a semi structured interview method. Nine producers, four using ionophorous coccidiostats and five without reliance in production accepted interview. During interviews participants were presented to research conducted with hops in production and consequences from ionophores in production. All participants thought the risk from pa

Abstract:

Globally, the largest source of atmospheric NH3 is domestic animal waste contributing 20-35 Tg of nitrogen per year. In North Carolina, hog waste accounts for 47% of all ammonia emissions in North Carolina. This is the result of a huge increase in hog population since the 1980?s from 3 million to 10 million. Currently swine waste is managed using Lagoon and Spray Technology (LST) also known as ?conventional? technology. A LST uses anaerobic lagoons to store the hog waste, and effluent from lagoons is sprayed on surrounding crops as a source of nutrients. This technology lead to a number source

Abstract:

The world is about to shift from fossil fuel dependency to independency. The national agenda of Sweden has put forth future goals of becoming a zero net greenhouse gas emitter by the year 2045 and before that, having an 80 % fossil fuel independent transportation fleet by 2030. In order to achieve these goals, the form of energy used in the transport sector needs to be changed into a more renewable solution. Biogas could be part of the solution. The aim of this report has been to review earlier research regarding the future biogas potential in Sweden and to examine how realistic and practicall

Abstract:

Master of Science<br>Geology<br>Matthew E. Brueseke<br>Previous K-Ar dating and petrography (Obradovich, 1978) have identified Pilot Knob as an ~3.4 (±0.06) Ma alkaline intrusive body. Bulk rock geochemistry obtained via XRF from four samples of Pilot Knob verifies the transitionally alkaline composition of the body, and new REE data also show enriched La, Ce, and Nd concentrations, consistent with rare earth element (REE) enrichment. Given the increased demand for REEs over the past ~30 years and China accounting for > 90% of global REE production (Kynicky, et al. 2012), it is important to
