Uncertainty Contributions To Species Specific Isotope Dilution Analysis, Rob Clough

School of Geography, Earth and Environmental Sciences Theses

Mercury speciation in solid sample matrices has been investigated using high performance liquid chromatography (HPLC) coupled with multicollector sector field (MCSF) and quadrupole (Q) inductively coupled plasma mass spectrometry (ICP-MS) for species specific isotope dilution mass spectrometry (IDMS). 199Hg enriched methylmercurychloride has been synthesised and recovered in the solid form for use as a spike material. The stability of methylmercury during the IDMS procedure was investigated using 199Hg and 13C labelled methylmercury isotopomers and ¹H Nuclear Magnetic Resonance spectroscopy. IntermoIecuJar exchange of the methylmercury halide counter ion was observed, the halide counter ion order of preference was l>Br>Cl. …

In Situ Measurement Of Trace Metals In Coastal Waters, Kate Ann Howell

School of Geography, Earth and Environmental Sciences Theses

This thesis describes the use of in situ and laboratory techniques for monitoring of trace metals and master variables in the environment. Chapter 1 presents a general overview of trace metals, their sources, sinks and roles in estuaries and near coastal zones, their general characteristics and the importance of their behaviour in estuaries. Filtration and commonly used analytical methods for trace metals detemriinations in natural waters are also discussed. Chapter 2 highlights the importance of colloids (in the size range 0.2 to 0.4 \im) to membrane clogging and concludes that cojloids account for a significant part of clogging of membrane …

Characterisation Of Nitric Oxide Synthase Activity In The Sea Anemone Aiptasia Pallida And An Evaluation Of Responses To Environmental Stress, Clare Emma Morrall

School of Geography, Earth and Environmental Sciences Theses

Studies were undertaken to investigate the presence of nitric oxide synthase (NOS; E.C. 1.14.13.39) activity in number of cnidarian species from shallow marine subtropical environments. Enzyme activity was assayed by measuring the conversion of 3H L-arginine to 3H L-citrulline (the citrulline assay). This assay was shown to be sufficiently sensitive for studies of this nature but was not optimised for use with cnidarian preparations. As a result, confidence in the accuracy of the generated assay results is limited. NOS activity was nevertheless demonstrated in the sea anemone A. pallida, in the zooxanthellae associated with A. pallida, Symbiodinium spp. and in …

The Oceanography And Modelling Of The Pontevedra Ria (Nw Spain), Andrew W. Dale

School of Geography, Earth and Environmental Sciences Theses

A multidisciplinary study the oceanography of the Pontevedra Ria (NW Spain), including hydrography, biogeochemistiy and biogeochemical modelling, has been performed. The hydrographical variability of the Pontevedra Ria was dependent on freshwater inputs and upwelling of nutrient-rich East North Atlantic Central Water from the shelf. Intrusions of the Poleward Current were also detected during winter. A stratified box model approach predicted that upwelling water fluxes into the ria of 2-4x10³ m³ s-1, of which >30% rises to the surface waters inside the ria. Freshwater residence time varied from ~4-9 d in the central ria and 1-4 d in the internal ria. …

Sediment Transport And Morphodynamics At An Estuary Mouth: A Study Using Coupled Remote Sensing And Numerical Modelling, Eduardo Siegle

School of Geography, Earth and Environmental Sciences Theses

The balance of the physical processes that drive the morphodynamics of a complex inlet system is investigated in this work. For this purpose, an innovative technique using coupled video imaging and numerical modelling has been used to study the relative importance of the driving forces that control the sandbar dynamics at the Teignmouth inlet system. The sandbars that form the ebb tidal delta are highly dynamic, leading to a cyclic morphological behaviour. Application of the numerical model (MIKE21 HD, NSW, ST) served two separate functions. The hydrodynamic model has been used for the image processing and, combined with the sediment …

Cross-Shore Sediment Transport Processes On Natural Beaches And Their Relation To Sand Bar Migration Patterns, Ismael De Jesus Marino Tapia

School of Biological and Marine Sciences Theses

During the last two decadess everalf ield studiesh ave shown a clear pattern in the cross-shores ediment transport processes on beaches. Outside the surf zone, the stronger onshore velocities under unbroken (Stokes-type) wave crests, produce a dominant onshore sediment transport. Inside the surf zone, strong offshore-directed mean currents (undertow) drive sediments offshore. It is of great interest for the scientific community to verify further the consistency of this pattern under different morphodynamic conditions, understand the underlying physics and quantify/parameterise this behaviour in order to improve the understanding of cross-shore sediment transport and simplify the modelling of beach profile change. The …

Studies On The Filamentous Gliding Bacteria Vitreoscilla Stercoraria, Laura Frances Biggs

School of Biological and Marine Sciences Theses

Strains of Vitreoscilla stercoraria were isolated from the environment and characterised. Cell width, motility and requirement of each strain for sodium chloride were investigated. Two strains were selected for further study and the effect of monensin and FCCP on growth of the strains was investigated. One strain of Vitreoscilla (LB13) was chosen for further study, cells from strain LB 13 were found to be 1.38 µm ± 0.041 (± 1 SEM, n=10) wide, were motile by gliding and had an optimum requirement for sodium chloride for growth of 43 mM. The organism was grown in batch culture and respiratory membranes …

Women's Rights: Reframing The Issues For The Future, Ariana Dubler, Anika Rahman, Kathy Rodgers, Jane M. Spinak

Faculty Scholarship

Good morning and welcome, everyone, to our panel on Women's Rights: Refraining the Issues for the Future. I am Kathy Rodgers. I'm from the class of 1973 of Columbia Law School, and I'm looking around this room – this is not what room A and B looked like back then! Everybody has a microphone, which is great, because we hope to have some good interactive discussion with all of you this morning.

I am also, in addition to being a Columbia Law alum, the president of NOW Legal Defense and Education Fund here in New York. For over thirty-two years, …

Hindu-Christian Dialogue: Revisiting The Tannirpalli Trinitys Original Vision, Klaus Klostermaier

Journal of Hindu-Christian Studies

Living in India from 1961 to 1970 I intensively and extensively participated in Hindu-Christian dialogue at various levels, academic as well as existential, and I came to know personally most of the then leading figures. While Hindu friends even then kept regularly imploring their Christian counterparts to persuade their churches to desist from proselytizing, they welcomed and encouraged dialogue. During the last decades the relationship between Hindus and Christians in India has visibly deteriorated.

Network Neutrality, Broadband Discrimination, Tim Wu

Faculty Scholarship

Communications regulators over the next decade will spend increasing time on conflicts between the private interests of broadband providers and the public's interest in a competitive innovation environment centered on the Internet. As the policy questions this conflict raises are basic to communications policy, they are likely to reappear in many different forms. So far, the first major appearance has come in the "open access" (or "multiple access") debate, over the desirability of allowing vertical integration between Internet Service Providers and cable operators. Proponents of open access see it as a structural remedy to guard against an erosion of the …

From Violent Crime To Terrorism: The Changing Basis Of The Federal, State And Local Law Enforcement Dynamic, Daniel C. Richman

Faculty Scholarship

Two lines of questions dominate discussions about how the nation ought to respond at home to the new (or rather newly perceived) terrorist threat: How do we ensure that information about potential terrorist activities is effectively gathered, shared, and used? And how do we ensure that the Government neither abuses the investigative authority we give it, nor demands more authority than it needs? Each line can profitably be pursued in its own terms. Yet to keep the conversations separate is to miss seeing how the very process of creating an effective domestic intelligence network may introduce a salutary level of …
