Ammonia Emissions From Slurry Applications To Land, Thomas Henry Misselbrook Jan 2005

Ammonia Emissions From Slurry Applications To Land, Thomas Henry Misselbrook

School of Biological and Marine Sciences Theses

Over the last 10-15 years there has been increasing concern within Europe as to the effects of ammonia emission and subsequent deposition to sensitive ecosystems, causing eutrophication and soil acidification. Transboundary transport of emissions has led to legislation at EC level with member states being given emission ceiling targets. Research has therefore aimed at quantifying national emissions, modelling emission processes and developing mitigation strategies. Agriculture accounts for >80% of total UK ammonia emission, therefore an accurate and robust model is required to estimate emissions from this sector. National inventory methodology has improved as the database of emission measurements and survey …


The Role Of Biological Interactions In Modifying The Effects Of Climate Change On Intertidal Assemblages, Phillipa Jane Moore Jan 2005

The Role Of Biological Interactions In Modifying The Effects Of Climate Change On Intertidal Assemblages, Phillipa Jane Moore

School of Biological and Marine Sciences Theses

The geographic distribution of most species is expected to alter as a consequence of global climate change. Predictions for the extent of these range shifts are frequently based on anticipated changes in temperature using a 'climate envelope' approach, which oversimplifies predictions because it does not consider interactions with other physical and biological factors. The aim of this thesis was to investigate how biological interactions modulate species responses to climate change. On many rocky shores in the NE Atlantic the interaction between limpets, barnacles and canopy forming macroalgae have an important role in structuring rocky shore communities. In particular, limpets control …


Environmental Impacts Of Technological Change In Bangladesh Agriculture: Farmers' Perceptions, Determinants, And Effects On Resource Allocation Decisions, S Rahman Jan 2005

Environmental Impacts Of Technological Change In Bangladesh Agriculture: Farmers' Perceptions, Determinants, And Effects On Resource Allocation Decisions, S Rahman

School of Geography, Earth and Environmental Sciences

This article measures the impact of modern technology adoption in raising farmers' environmental awareness and the impact of farmers' environmental awareness on resource use by utilizing survey data from 21 villages in three agro‐ecological regions of Bangladesh. The econometric analysis is based on the application of the Tobit model explaining farmers' environmental awareness in the first stage and a profit function examining environmental awareness and resource use relationships in the second stage. Results reveal that the “level” and “duration” of involvement with modern technology raises farmers' environmental awareness, and that farmers' environmental awareness reduces resource use including chemicals. Farmers, who …


Geography, Citizenship And Volunteering: Some Uses Of The Higher Education Active Community Fund In Geography, Richard Yarwood Jan 2005

Geography, Citizenship And Volunteering: Some Uses Of The Higher Education Active Community Fund In Geography, Richard Yarwood

School of Geography, Earth and Environmental Sciences

Voluntary work with local communities has been advocated as beneficial for geography students, higher education institutions and the public. In England, the Higher Education Active Community Fund (HEACF) has recently been established by the Government to encourage staff and students in higher education to undertake voluntary work in local communities. This paper reports on the use of HEACF funding to develop voluntary work projects for geography students at the University of Plymouth. It examines the student experience of voluntary working and concludes that it helps students to develop as both geographers and active citizens in their local communities.


The Correlation Grid: Analysis Of Synchronous Spiking In Multi-Dimensional Spike Train Data And Identification Of Feasible Connection Architectures, L Stuart, M Walter, R Borisyuk Jan 2005

The Correlation Grid: Analysis Of Synchronous Spiking In Multi-Dimensional Spike Train Data And Identification Of Feasible Connection Architectures, L Stuart, M Walter, R Borisyuk

School of Engineering, Computing and Mathematics

This paper presents a visualization technique specifically designed to support the analysis of synchronous firings in multiple, simultaneously recorded, spike trains. This technique, called the correlation grid, enables investigators to identify groups of spike trains, where each pair of spike trains has a high probability of generating spikes approximately simultaneously or within a constant time shift. Moreover, the correlation grid was developed to help solve the following reverse problem: identification of the connection architecture between spike train generating units, which may produce a spike train dataset similar to the one under analysis. To demonstrate the efficacy of this approach, results …

The Influence Of Ethics And Social Responsibility On Grocery Shopping Behaviour In The Uk, Juliet Emma Memery Jan 2005

The Influence Of Ethics And Social Responsibility On Grocery Shopping Behaviour In The Uk, Juliet Emma Memery

Plymouth Business School Theses

Consumption as an aspect of most people's lives in affluent societies is widely acknowledged as having become increasingly important (Newholm, 2005). We consume more, and consume more often, than previous generations (Durning, 1992) meaning the actions we make and the decisions we take have greater impact than ever before on the world we inhabit. For many their involvement with consumption goes beyond the act of purchase (Oilman, 1998) to include complex ethical dimensions. The relationship between ethics and social responsibility (E&SR) and consumption choices has received growing attention over recent years, resulting in the topic of 'sustainable consumption' becoming a …


International Freight Transport Multimodal Development In Developing Countries: The Case Of Bangladesh, Dewan Mohammad Zahurul Islam Jan 2005

International Freight Transport Multimodal Development In Developing Countries: The Case Of Bangladesh, Dewan Mohammad Zahurul Islam

Plymouth Business School Theses

An efficient transport system is essential for an efficient supply chain to facilitate international trade. To utilise all cheaper resources, such as labour in Bangladesh, companies receive supplies from one coxintry (e.g. in Hong Kong), produce the products in another country, and sell them in other countries (e.g. European countries). Thus the production and consumption has turned into a global activity with transport filling the gaps among them. To perform the transport function a carrier may require the use of more than one mode, the so-called multimodal transport. Multimodal transport, an integrated systems approach, can be defined as the most …

Teaching Catholicism, As Easy As Play., Tj Lynch Oct 2004

Teaching Catholicism, As Easy As Play., Tj Lynch

Plymouth Institute of Education

In society, sport often connotes a religious reference. Sport as a medium for learning is directly related to the curriculum key learning area of Health and Physical Education (HPE), as it can be used as a vehicle for teaching the HPE concepts. The unique ‘learning through movement’ nature of HPE enables a focus on the physical dimension. Hence, sport interacts intimately with the strand ‘developing concepts and skills for physical activity’, which is embedded in the Queensland HPE syllabus. In the physical dimension students can be presented with many practical and social experiences that require acknowledgement and reflection upon Catholic …


A Phase I/Ii Study Of Gemcitabine And Fractionated Cisplatin In An Outpatient Setting Using A 21-Day Schedule In Patients With Advanced And Metastatic Bladder Cancer, Sa Hussain, Dd Stocken, P Riley, Dh Palmer, Et Al Aug 2004

A Phase I/Ii Study Of Gemcitabine And Fractionated Cisplatin In An Outpatient Setting Using A 21-Day Schedule In Patients With Advanced And Metastatic Bladder Cancer, Sa Hussain, Dd Stocken, P Riley, Dh Palmer, Et Al

Peninsula Medical School

A randomised phase III trial of MVAC (methotrexate, vincristine, doxorubicin, cisplatin) vs gemcitabine and cisplatin (GC) (G 1000 mg m(-2) days 1, 8, and 15 plus C 70 mg m(-2) day 2, q 4 wks) indicated GC had similar efficacy and lower toxicity (JCO 2000). Significant haematologic toxicities in the GC arm occurred on day 15, necessitating dose adjustments in 37% of cycles. We conducted a phase I/II dose escalation trial using GC on a 21-day cycle, with G and C split between days 1 and 8. The objective of the study to define maximum-tolerated dose and dose-limiting toxicity (DLT), …


The Representation Of Neural Data Using Visualization, Ej Stuart Jun 2004

The Representation Of Neural Data Using Visualization, Ej Stuart

School of Engineering, Computing and Mathematics

Currently, the focus of research within Information Visualization is steering towards genomic data visualization due to the level of activity that the Human Genome Project has generated. However, the Human Brain project, renowned within Neuroinformatics, is equally challenging and exciting. Its main aim is to increase current understanding of brain function such as memory, learning, attention, emotions and consciousness. It is understood that this task will require the ‘integration of information from the level of the gene to the level of behaviour'. The work presented in this paper focuses on the visualization of neural data. More specifically, the data being …

An Intelligent Navigation System For An Autonomous Underwater Vehicle, Dedy Loebis Jan 2004

An Intelligent Navigation System For An Autonomous Underwater Vehicle, Dedy Loebis

School of Engineering, Computing and Mathematics Theses

The work in this thesis concerns with the development of a novel multisensor data fusion (MSDF) technique, which combines synergistically Kalman filtering, fuzzy logic and genetic algorithm approaches, aimed to enhance the accuracy of an autonomous underwater vehicle (AUV) navigation system, formed by an integration of global positioning system and inertial navigation system (GPS/INS). The Kalman filter has been a popular method for integrating the data produced by the GPS and INS to provide optimal estimates of AUVs position and attitude. In this thesis, a sequential use of a linear Kalman filter and extended Kalman filter is proposed. The former …


Ultrastructure And Function Of Respiratory Cilia In Critical Illness, Joanne Hosking Jan 2004

Ultrastructure And Function Of Respiratory Cilia In Critical Illness, Joanne Hosking

School of Biomedical Sciences Theses

Approximately one in eleven hospital patients suffer a nosocomial infection. Intensive care patients are at particular risk and nosocomial pneumonia especially is a problem in the intensive care unit (ICU). The mucociliary transport system is the major defence mechanism against such infection and whilst its efficiency has been shown to be decreased in ICU patients there are few reports in the literature describing the ultrastructure of the respiratory epithelium in this patient group. The principal aims of this study included an investigation of the ultrastructure of the respiratory ciliated epithelium in ICU patients, together with an assessment of the impact …

Aqueous & Non-Aqueous Phase Tracer Migration Through Differing Soil Textures, Anthony Johnson Jan 2004

Aqueous & Non-Aqueous Phase Tracer Migration Through Differing Soil Textures, Anthony Johnson

School of Geography, Earth and Environmental Sciences Theses

The National Grid Transco Company sponsored this project in order to promote the understanding of NAPL migration through b-horizon soils and retarding effects upon non aqueous species migration. Soil structure and texture was also studied using conservative (Bromide) and non-conservative (Phosphate) tracers. Experimental data was produced using a laboratory ½ metre scale automated lysimeter designed and constn1cted at Plymouth. The tracers were compared before oil injection, to calibrate differences in soil texture, and after oil injection to detect any changes in the flow patterns caused by the oil injection. It was found that the Crediton, Sollom and Conway soils respectively …

Foraminiferal Distribution And Sequence Stratigraphy Of Oxfordian Successions In The Wessex/Anglo-Paris Basin, Melissa Jane Oxford

School of Geography, Earth and Environmental Sciences Theses

The use of micropalaeontology within a sequence stratigraphic context is rapidly emerging as a valuable tool for the recognition of ancient cycles and sequences. This study shows how micropalaeontology can be used to develop insights into sequence stratigraphic interpretations. A micropalaeontology study of two Upper Jurassic, Oxfordian successions from the South . Dorset Coast, U.K. and the Normandy Coast, France provide the basis for this study. A near continuous succession of the Oxfordian from South Dorset and Normandy were obtained, and foraminifera extracted. Examination of the fauna revealed representatives from 23 families, comprising 36 genera and 126 species. All species …


Landslide Investigation In The Río Aguas Catchment, Southeast Spain, Andrew Barrie Hart Jan 2004

Landslide Investigation In The Río Aguas Catchment, Southeast Spain, Andrew Barrie Hart

School of Geography, Earth and Environmental Sciences Theses

Many remote and/or rural communities Uve under the threat of major landslide activity. These remote areas are also increasingly the focus of development programmes which, without careful consideration of the ground conditions, will be at risk. The cost of mitigating against landslide activity can also be extremely high, possibly making prevention or avoidance the better long-term option. It is, therefore, of prime importance to assess the type and magnitude of the landslide activity affecting an area, particularly during the feasibility and planning stages of any project. The most straightforward approach to any landslide investigation is the compilation of a landslide …


Remote Sensing Of Optically Active Marine Components, Raghu Chandra Nagur Cherukuru Jan 2004

Remote Sensing Of Optically Active Marine Components, Raghu Chandra Nagur Cherukuru

School of Biological and Marine Sciences Theses

Remote sensing is an efficient tool to monitor the aquatic ecology. The optical signature in coastal marine environment is a reflection of the complex distribution of optically active marine components. It is essential to understand the relationship between the remote sensing signal and marine constituent material to take advantage of high resolution remote sensing data available from spaceborne and airborne platforms. The objective of this research was to develop a semi-analytical forward model to predict the remote sensing optical signature in coastal waters dominated by non-planktonic material. Laboratory and in situ measurements collected over a5 year period (1998-2003) were used …


The Interference Free Determination Of Selenium In Environmental And Clinical Samples By Icp-Ms, Justine Clare Turner Jan 2004

The Interference Free Determination Of Selenium In Environmental And Clinical Samples By Icp-Ms, Justine Clare Turner

School of Geography, Earth and Environmental Sciences Theses

The determination of selenium in environmental and clinical samples by ICP-MS is complicated by both poor sensitivity and severe interferences resulting from both the sample matrix and the argon plasma. The purpose of this study was to investigate ways of overcoming these problems thus enabling Se to be determined both accurately and precisely. A novel procedure for the accurate determination of selenium in serum using electrothermal vaporisation inductively coupled plasma mass spectrometry (ETV-ICP-MS) has been developed. A simple 1:20 dilution of the serum with 1% nitric acid negates the need for a lengthy sample digestion procedure. Several of the interferences …
