Landfill Design, Construction And Non-Invasive Monitoring, Amanda Jane Hopper Jan 1998

Landfill Design, Construction And Non-Invasive Monitoring, Amanda Jane Hopper

School of Geography, Earth and Environmental Sciences Theses

Three techniques are investigated in order to assess their applicability for use in landfill design, construction and monitoring. Firstly, an assessment is made of QA procedures during liner construction through the detailed evaluation of two case studies. Construction QA procedures on-site are compared to available guidelines. The research illustrates the requirement for standardised, regulated QA procedures on landfill sites in order to provide a recognised framework for construction control. The Moisture Condition Value Test (MCV) is evaluated for use as a method of monitoring the placement of compacted clay landfill liners. London Clay and Mercia Mudstone, collected from the QA …


Development Of A Low Pressure-Inductively Coupled Plasma-Ion Source For Mass Spectrometry, Gavin Thomas O'Connor Jan 1998

Development Of A Low Pressure-Inductively Coupled Plasma-Ion Source For Mass Spectrometry, Gavin Thomas O'Connor

School of Geography, Earth and Environmental Sciences Theses

A low pressure-inductively coupled plasma (LP-ICP) ion source has been investigated for the production of atomic and molecular ions for mass spectrometry (MS). A dedicated LPICP- MS was constructed, by modifying a Hewlett Packard mass selective detector, to detect ions from the LP-ICP. The ion sampling interface and ion optics were designed using established theory and the use of a computer simulation program. Perfluorotributylamine was continuously introduced into the LP-ICP, via a molecular leak, and the ion sampling interface, plasma forward power, and plasma gas flow rates, were optimised. When the LP-ICP ion source was sustained at 6W with a …


Modelling And Monitoring Of Phosphorus Transport And Speciation In Soil, Darren Michael William Peat Jan 1998

Modelling And Monitoring Of Phosphorus Transport And Speciation In Soil, Darren Michael William Peat

School of Geography, Earth and Environmental Sciences Theses

Flow through soil into groundwater has been classically conceptualised as taking place through a set of aligned capillary tubes. In solute transport models these approximations are also present. Pore-Cor (a network model) has been used to model the void structure of soil by using water retention and mercury porosimetry curves. The model successfully predicts trends in saturated hydraulic conductivity. The effect of the assumptions used in the Pore-Cor geometry have been investigated by comparing of two dimensional slices of the simulated networks with two dimensional image analysis data. The geometric limitations of the model cause packing inefficiencies which prevent the …


Particle-Water Interactions Of Hydrophobic Organic Micropollutants In Marine Systems, M. Carl Rawling Jan 1998

Particle-Water Interactions Of Hydrophobic Organic Micropollutants In Marine Systems, M. Carl Rawling

School of Geography, Earth and Environmental Sciences Theses

An understanding of the reactivity of hydrophobic organic micropollutants (HOMs) is of paramount importance to water quality managers because of their toxicity, persistence, and liability to bioaccumulate. In this study, the role played by the main estuarine variables (organic matter, suspended particulate matter [SPM], particle type and salinity) on HOM behaviour was investigated by employing samples from estuaries with different geochemical signatures (Chupa, Russia, and the Dart, Plym, Beaulieu and Carnon, U K ) . A laboratory-based technique was developed for the determination of the solubility and sorptive behaviour of HOMs using 14C-labelled, beta-emitting organic compounds (2,2\5,5'-tetrachlorobiphenyl (2,2’5,5'-TCB), bis(2-ethylhexyl)phthalate ester …


In-Situ Preconcentration Of Trace Metals In Natural Waters And Brines With Analysis By Flow Injection Atomic Spectrometry, Robert Anthony Nickson Jan 1998

In-Situ Preconcentration Of Trace Metals In Natural Waters And Brines With Analysis By Flow Injection Atomic Spectrometry, Robert Anthony Nickson

School of Geography, Earth and Environmental Sciences Theses

Atomic spectrometric techniques such as ICP-MS offer exceptional sensitivity and multi-element capability for trace metal analysis but the formation of polyatomic ions (particularly below m/z = 80) can cause serious interferences. Such interfering species may be introduced via precursor atoms in atmospheric gases, the sample matrix or impurities in the reagents and gases. There is an environmental need to establish rapid multi-element methods of analysis for trace metals in environmental waters and the subsequent speciation of these trace elements. Natural waters, particularly those with a high dissolved solids content such as sea water are difficult to analyse directly by ICP …


On-Line Sample Pretreatment Of Environmental Samples For Use With Atomic Spectrometry, James Robert Murphy Jan 1998

On-Line Sample Pretreatment Of Environmental Samples For Use With Atomic Spectrometry, James Robert Murphy

School of Geography, Earth and Environmental Sciences Theses

The objective of this study was to develop novel techniques for on-line sample pre-treatment for use with atomic spectroscopy. Preconcentration of the analytes using either complexation of the analyte(s) on an analytical column or by in-situ (in atomiser) trapping on a pre-coated graphite tube has been used. The samples were manipulated using flow injection analysis and detection achieved in most cases by ETAAS. All aspects of the study are supported by reference to the literature. Using the above approach, a new method has been developed to determine mercury in environmental (sediment) and biological (tuna fish) samples. This approach successfully achieved …

Catch Me If You Can! Resolving The Ethical Tragedies In The Brave New World Of Jury Selection, José F. Anderson Jan 1998

Catch Me If You Can! Resolving The Ethical Tragedies In The Brave New World Of Jury Selection, José F. Anderson

All Faculty Scholarship

Since the Supreme Court's opinion in Batson v. Kentucky, the rules and tools available to lawyers for selecting juries have changed dramatically from what they had been for decades in American courtrooms. The Court's well intentioned effort in Batson to attempt to eliminate racial discrimination from the process of jury selection set in motion a series of modifications in lawyer decision making which have changed how lawyers fill the jury box. Prior to Batson, the sacrosanct tool known as the peremptory challenge had been virtually unassailable as a jury selection weapon. Abuses by prosecutors, particularly in the southern United States, …


U.S. “Methods Awareness” (Methodenbewußtsein) For German Jurists, James Maxeiner Jan 1998

U.S. “Methods Awareness” (Methodenbewußtsein) For German Jurists, James Maxeiner

All Faculty Scholarship

The purpose of this contribution is to help develop Methods Awareness in German jurists unfamiliar with American law. It shows how distant from German understanding present-day American practice is. It proceeds from Fikentscher's thumbnail sketch of German Prevailing Teaching: "this method starts from norm-thinking, therefore thinks in rules, that are applied to the case at hand." It refers to the core elements of this teaching, namely the place of the legal norm (Rechtssatz) in the legal order (Rechtsordnung) and its application to a particular set of facts (i.e., subsumption), and discusses the significance of these concepts in American law. It …

The Generation Of Compound Nominals To Represent The Essence Of Text The Commix System, Jennifer Vivien Norris Jan 1998

The Generation Of Compound Nominals To Represent The Essence Of Text The Commix System, Jennifer Vivien Norris

Other Faculty of Science and Engineering Theses

This thesis concerns the COMMIX system, which automatically extracts information on what a text is about, and generates that information in the highly compacted form of compound nominal expressions. The expressions generated are complex and may include novel terms which do not appear themselves in the input text. From the practical point of view, the work is driven by the need for better representations of content: for representations which are shorter and more concise than would appear in an abstract, yet more informative and representative of the actual aboutness than commonly occurs in indexing expressions and key terms. This additional …


The Later Political Career Of R.A. Butler 1951-1964, Nicholas Adam Patch Jan 1998

The Later Political Career Of R.A. Butler 1951-1964, Nicholas Adam Patch

Other Faculty of Arts, Humanities and Business Theses

R. A. Butler was one of the most influential and yet enigmatic of twentieth century politicians. He did more than anyone to stimulate the revival of post-war Conservatism, which led to three consecutive general election victories. He was a powerful figure in all Conservative Cabinets from 1951 to 1964, serving in each of the three main offices of state, and he nearly became Prime Minister twice. This thesis seeks to challenge the commonly held belief that the post-war Conservative policies developed by Butler represented an acceptance of the mixed-economy welfare-state, as established by the Labour Government between 1945 and 1951. …


Theatre Of Life: Rituals, Transition And Progression Among The Igbo, Mary-Blossom Chinyelum Okafor Jan 1998

Theatre Of Life: Rituals, Transition And Progression Among The Igbo, Mary-Blossom Chinyelum Okafor

Other Faculty of Arts, Humanities and Business Theses

The Igbo are perpetual celebrants of life. Their need to celebrate life means that the Igbo will ceaselessly try to make the best of life, because they believe that although life may be full of uncertainties, such uncertainties are only temporary. So, the Igbo will celebrate whatever fortune brings in the knowledge that tomorrow will definitely be different. It is this insight into the transitory nature of things that makes the Igbo celebrate life, aware that time has the ability to obliterate uncelebrated memories. In the researcher's opinion, this work has succeeded in establishing the fact that the study and …


The Influence Of Nitrification In Determining The Supply, Distribution And Fate Of Nitrogen In Grassland Soils, David John Hatch Jan 1998

The Influence Of Nitrification In Determining The Supply, Distribution And Fate Of Nitrogen In Grassland Soils, David John Hatch

Other Faculty of Science and Engineering Theses

The microbiology of nitrification has been extensively studied, but the ecology and environmental impact of the process has received less attention. The reason for this has more to do with the difficulties of conducting field experiments to examine the links with other processes which cause losses of nitrogen, than a failure to appreciate its importance in agricultural systems. This project was designed to overcome some of the limitations of existing field techniques to enable simultaneous measurements of nitrification and the major processes of N supply (mineralization) and N loss (denitrification and leaching) to be examined. The study proceeded in three …


A Visual Design Method And Its Application To High Reliability Hypermedia Systems, Robert Malcolm Newman Jan 1998

A Visual Design Method And Its Application To High Reliability Hypermedia Systems, Robert Malcolm Newman

Other Faculty of Science and Engineering Theses

This work addresses the problem of the production of hypermedia documentation for applications that require high reliability, particularly technical documentation in safety critical industries. One requirement of this application area is for the availability of a task-based organisation, which can guide and monitor such activities as maintenance and repair. In safety critical applications there must be some guarantee that such sequences are correctly presented. Conventional structuring and design methods for hypermedia systems do not allow such guarantees to be made. A formal design method that is based on a process algebra is proposed as a solution to this problem. Design …
