Selectivity Control In Pt-Catalyzed Cinnamaldehyde Hydrogenation, Lee J. Durndell, Christopher M.A. Parlett, Nicole S. Hondow, Mark A. Isaacs, Karen Wilson, Adam F. Lee
Selectivity Control In Pt-Catalyzed Cinnamaldehyde Hydrogenation, Lee J. Durndell, Christopher M.A. Parlett, Nicole S. Hondow, Mark A. Isaacs, Karen Wilson, Adam F. Lee
School of Geography, Earth and Environmental Sciences
AbstractChemoselectivity is a cornerstone of catalysis, permitting the targeted modification of specific functional groups within complex starting materials. Here we elucidate key structural and electronic factors controlling the liquid phase hydrogenation of cinnamaldehyde and related benzylic aldehydes over Pt nanoparticles. Mechanistic insight from kinetic mapping reveals cinnamaldehyde hydrogenation is structure-insensitive over metallic platinum, proceeding with a common Turnover Frequency independent of precursor, particle size or support architecture. In contrast, selectivity to the desired cinnamyl alcohol product is highly structure sensitive, with large nanoparticles and high hydrogen pressures favoring C = O over C = C hydrogenation, attributed to molecular surface …

Creep Cavitation Bands Control Porosity And Fluid Flow In Lower Crustal Shear Zones, L Menegon, F Fusseis, H Stunitz, X Xiao
School of Geography, Earth and Environmental Sciences
Shear zones channelize fluid flow in Earth’s crust. However, little is known about deep crustal fluid migration and how fluids are channelized and distributed in a deforming lower crustal shear zone. This study investigates the deformation mechanisms, fluid-rock interaction, and development of porosity in a monzonite ultramylonite from Lofoten, northern Norway. The rock was deformed and transformed into an ultramylonite under lower crustal conditions (temperature = 700–730 °C, pressure = 0.65–0.8 GPa). The ultramylonite consists of feldspathic layers and domains of amphibole + quartz + calcite, which result from hydration reactions of magmatic clinopyroxene. The average grain size in both …
Determinants Of Crop Diversity In The Regions Of Bangladesh (1990–2008), S Rahman, Mmh Kazal
Determinants Of Crop Diversity In The Regions Of Bangladesh (1990–2008), S Rahman, Mmh Kazal
School of Geography, Earth and Environmental Sciences
The paper measures the level of crop diversity and identifies factors influencing diversification using a panel data of 17 regions of Bangladesh covering a 19 year period (1990–2008). Results revealed the trends that agricultural areas allocated to high-yielding variety rice, spices and vegetables has increased, while areas cultivating traditional rice, minor cereals, oilseeds, pulses, jute and sugarcane has declined at variable rates across regions with significant differences. The level of crop diversity is also significantly different across regions and has decreased in 2008 from its 1990 level in most regions except Faridpur, Khulna and Sylhet. Among the determinants, an increase …
The Role Of Gravitational Instabilities In Deposition Of Volcanic Ash, I Manzella, C Bonadonna, Jc Phillips, H Monnard
The Role Of Gravitational Instabilities In Deposition Of Volcanic Ash, I Manzella, C Bonadonna, Jc Phillips, H Monnard
School of Geography, Earth and Environmental Sciences
Volcanic ash is a significant hazard for areas close to volcanoes and for aviation. Gravitational instabilities forming at the bottom of spreading volcanic clouds have been observed in many explosive eruptions. Here we present the first quantitative description of the dynamics of such instabilities, and correlate this with the characteristics of the fall deposit from observations of the 4 May 2010 Eyjafjallajökull (Iceland) eruption. Gravitational instabilities initially took the form of downward-propagating fingers that formed continuously at the base of the cloud, and appeared to be advected passively at the crosswind speed. Measurements of finger propagation are consistent with initial …

School of Geography, Earth and Environmental Sciences
Sediment fluxes in aquatic environments are crucially dependent on bedform dynamics. However, sediment-flux predictions rely almost completely on clean-sand studies, despite most environments being composed of mixtures of non-cohesive sands, physically cohesive muds and biologically cohesive extracellular polymeric substances (EPS) generated by microorganisms. EPS associated with surficial biofilms are known to stabilize sediment and increase erosion thresholds. Here we present experimental data showing that the pervasive distribution of low levels of EPS throughout the sediment, rather than the high surficial levels of EPS in biofilms, is the key control on bedform dynamics. The development time for bedforms increases by up …

Bicyclic Naphthenic Acids In Oil Sands Process Water: Identification By Comprehensive Multidimensional Gas Chromatography-Mass Spectrometry., Michael J. Wilde, Charles E. West, Alan G. Scarlett, David Jones, Richard A. Frank, L. Mark Hewitt, Steven J. Rowland
School of Geography, Earth and Environmental Sciences
Although bicyclic acids have been reported to be the major naphthenic acids in oil sands process-affected water (OSPW) and a well-accepted screening assay indicated that some bicyclics were the most acutely toxic acids tested, none have yet been identified. Here we show by comprehensive multidimensional gas chromatography-mass spectrometry (GC×GC-MS), that >100 C8-15 bicyclic acids are typically present in OSPW. Synthesis or purchase allowed us to establish the GC×GC retention times of methyl esters of numerous of these and the mass spectra and published spectra of some additional types, allowed us to identify bicyclo[2.2.1]heptane, bicyclo[3.2.1]octane, bicyclo[4.3.0]nonane, bicyclo[3.3.1]nonane and bicyclo[4.4.0]decane acids in …
Modelling The Transfer Of Supraglacial Meltwater To The Bed Of Leverett Glacier, Southwest Greenland, Cc Clason, Dwf Mair, Pw Nienow, Id Bartholomew, Et Al
Modelling The Transfer Of Supraglacial Meltwater To The Bed Of Leverett Glacier, Southwest Greenland, Cc Clason, Dwf Mair, Pw Nienow, Id Bartholomew, Et Al
School of Geography, Earth and Environmental Sciences
Meltwater delivered to the bed of the Greenland Ice Sheet is a driver of variable ice-motion through changes in effective pressure and enhanced basal lubrication. Ice surface velocities have been shown to respond rapidly both to meltwater production at the surface and to drainage of supraglacial lakes, suggesting efficient transfer of meltwater from the supraglacial to subglacial hydrological systems. Although considerable effort is currently being directed towards improved modelling of the controlling surface and basal processes, modelling the temporal and spatial evolution of the transfer of melt to the bed has received less attention. Here we present the results of …
Linkages Between Reach-Scale Physical Habitat And Invertebrate Assemblages In Upland Streams, Victoria S. Milner, Nigel J. Willby, David J. Gilvear, Charles Perfect
Linkages Between Reach-Scale Physical Habitat And Invertebrate Assemblages In Upland Streams, Victoria S. Milner, Nigel J. Willby, David J. Gilvear, Charles Perfect
School of Geography, Earth and Environmental Sciences
Determining the influence of physical habitat on biological structure in minimally disturbed settings is important if the effects of alterations to physical habitat are to be understood. This study tested whether reach-scale differences in physical habitat influence macroinvertebrate community composition at 24 sites in the Cairngorm Mountains, Scotland. Stream reaches were classified into channel types based on a geomorphic typology (i.e. step-pool, bedrock, plane-bed and pool-riffle). PERMANOVA indicated an overall significant relationship between the geomorphic typology and macroinvertebrate species-level composition, and among all combinations of channel types (such as steppool and pool-riffle, step-pool and bedrock). Most channel types were dominated …
Whether Crop Diversification Is Energy Efficient: An Empirical Analysis From Bangladesh, S Rahman, Mmh Kazal
Whether Crop Diversification Is Energy Efficient: An Empirical Analysis From Bangladesh, S Rahman, Mmh Kazal
School of Geography, Earth and Environmental Sciences
This study examines whether crop diversification provides economy in energy use and improves technical energy efficiency using a large survey data of 2,075 farms from 20 sub-districts of 17 districts in Bangladesh by applying a stochastic input-distance function approach. The results reveal that cereal production significantly increases energy use by 0.14% for every one percent increase` in output. Renewable source of energy constitutes 59.6% of total inputs and labour energy alone constitutes 39%. Significant output complementarity exists between cereal and oilseed enterprises but competition exist between jute with pulse and/or oilseed enterprises. The mean technical energy efficiency is estimated at …
Utilising Probabilistic Techniques In The Assessment Of Extreme Coastal Flooding Frequency- Magnitude Relationships Using A Case Study From South-West England, Michael Robert Zordan Whitworth
Utilising Probabilistic Techniques In The Assessment Of Extreme Coastal Flooding Frequency- Magnitude Relationships Using A Case Study From South-West England, Michael Robert Zordan Whitworth
School of Geography, Earth and Environmental Sciences Theses
Recent events such as the New Orleans floods and the Japanese tsunami of 2011 have highlighted the uncertainty in the quantification of the magnitude of natural hazards. The research undertaken here has focussed on the uncertainty in evaluating storm surge magnitudes based on a range of statistical techniques including the Generalised Extreme Value distribution, Joint Probability and Monte Carlo simulations. To support the evaluation of storm surge frequency magnitude relationships a unique hard copy observed sea level data set, recording hourly observations, was acquired and digitised for Devonport, Plymouth, creating a 40 year data set. In conjunction with Devonport data, …

Socio-Economic Determinants Of Modern Agricultural Technology Adoption In Multiple Food Crops And Its Impact On Productivity And Food Availability At The Farm-Level: A Case Study From South-Eastern Nigeria, Chidiebere Daniel Chima
Socio-Economic Determinants Of Modern Agricultural Technology Adoption In Multiple Food Crops And Its Impact On Productivity And Food Availability At The Farm-Level: A Case Study From South-Eastern Nigeria, Chidiebere Daniel Chima
School of Geography, Earth and Environmental Sciences Theses
Farmers generally produce multiple crops while selectively adopting modern technologies to meet various needs. The main aim of this study is, therefore, to identify the range of socio-economic factors influencing the adoption of modern agricultural technology in multiple food crops and the corresponding impacts on productivity and food availability at the farm-level in South-eastern Nigeria. In this study, three major food crops (i.e., rice, yam and cassava) and two elements of modern technologies (i.e., HYV seeds and inorganic fertilizers) are considered. The hypotheses of the study are that inverse farm size – technology adoption, size – productivity, size- profitability and …
Field Observations Of Wave Induced Coastal Cliff Erosion, Cornwall, Uk, Claire Siobhan Earlie
Field Observations Of Wave Induced Coastal Cliff Erosion, Cornwall, Uk, Claire Siobhan Earlie
School of Biological and Marine Sciences Theses
Coastal cliff erosion is a widespread problem that threatens property and infrastructure along many of the world’s coastlines. The management of this risk calls for robust quantification of cliff erosion rates, which are often difficult to obtain along rocky coasts. Quantification of sea-cliff rates of retreat on annual to decadal time scales has typically been limited to rapidly eroding soft rock coastlines. Rates of erosion used for shoreline management in the UK are generally based on analysis of historic maps and aerial photographs which, in rocky coast environments, does not wholly capture the detail and timing at which the processes …
Investigation Of The Risks Of Entry And Spread Of Bvd In Herds Participating In A Regional Bvd Control Programme In The South West, Rebecca Mary Butland
Investigation Of The Risks Of Entry And Spread Of Bvd In Herds Participating In A Regional Bvd Control Programme In The South West, Rebecca Mary Butland
School of Biological and Marine Sciences Theses
Bovine Viral Diarrhoea (BVD) is estimated to cost the UK cattle industry £40 million annually, the third most costly disease facing the agricultural industry. BVD produces a range of symptoms in cattle including scouring, pneumonia, poor fertility, reduced growth rates and lowered milk yields. The most common route of transmission is through persistently infected (PI) animals shedding the virus to other cattle. PI animals can only develop pre-partum when the BVD virus crosses the placenta from the dam to the foetus. If infection occurs during the first 110 to 150 days of gestation, the foetus is immune-incompetent and the lymphocytes …
Swash Zone Dynamics Of Coarse-Grained Beaches During Energetic Wave Conditions, Luis Pedro Almeida
Swash Zone Dynamics Of Coarse-Grained Beaches During Energetic Wave Conditions, Luis Pedro Almeida
School of Biological and Marine Sciences Theses
Coarse-grained beaches, such as pure gravel (PG), mixed sand-gravel (MSG) and composite (CSG) beaches, can be considered as one of the most resilient non-cohesive morpho-sedimentary coastal environments to energetic wave forcing (e.g., storms). The hydraulically-rough and permeable nature of gravel (D50 > 2 mm), together with the steep (reflective) beach face, provide efficient mechanisms of wave energy dissipation in the swash zone and provide a natural means of coastal defence. Despite their potential for shore protection very little is known about the response of these environments during high energetic wave conditions. Field measurements of sediment transport and hydrodynamics on coarse-grained beaches …
Community Resilience And Social Memory, Ga Wilson
Community Resilience And Social Memory, Ga Wilson
School of Geography, Earth and Environmental Sciences
The notion of ‘resilience’ is rapidly emerging as a research topic in its own right, with the notion of ‘social resilience’ rapidly gaining importance. Yet, due to the relative novelty of the research field, discussions about processes of social resilience are not yet fully developed, especially with regard to how the inbuilt ‘memory’ of a local community helps shape resilience pathways (social memory). Interlinkages between social memory and community resilience are the focus of this study, with emphasis on analysis of the importance of rites, traditions and social learning processes for shaping community resilience/ vulnerability.

Adverse Outcome Pathways Can Drive Non‐Animal Approaches For Safety Assessment, N Burden, F Sewell, Me Andersen, A Boobis, Jk Chipman, Mtd Cronin, Th Hutchinson, I Kimber, M Whelan
School of Geography, Earth and Environmental Sciences
AbstractAdverse Outcome Pathways (AOPs) provide an opportunity to develop new and more accurate safety assessment processes for drugs and other chemicals, and may ultimately play an important role in regulatory decision making. Not only can the development and application of AOPs pave the way for the development of improved evidence‐based approaches for hazard and risk assessment, there is also the promise of a significant impact on animal welfare, with a reduced reliance on animal‐based methods. The establishment of a useable and coherent knowledge framework under which AOPs will be developed and applied has been a first critical step towards realizing …

AbstractSubmarine landslide deposits have been mapped around many volcanic islands, but interpretations of their structure, composition, and emplacement are hindered by the challenges of investigating deposits directly. Here we report on detailed observations of four landslide deposits around Montserrat collected by Remotely Operated Vehicles, integrating direct imagery and sampling with sediment core and geophysical data. These complementary approaches enable a more comprehensive view of large‐scale mass‐wasting processes around island‐arc volcanoes than has been achievable previously. The most recent landslide occurred at 11.5–14 ka (Deposit 1; 1.7 km3) and formed a radially spreading hummocky deposit that is morphologically similar to many …

School of Geography, Earth and Environmental Sciences
Paint flaking off abandoned vessels or generated during boat repair is hazardous to human health and wildlife. In this study, a means of screening paint fragments using a field portable-X-ray fluorescence (FP-XRF) spectrometer is described. The technique is capable of delivering rapid, surficial measurements of Ba, Cu, Pb and Zn down to concentrations less than 150 μg g(-1), and Sn and Cr to concentrations of a few hundred μg g(-1). Application of the technique to fragments collected from slipways, yards, hardstandings, abandoned boats and ships undergoing maintenance throughout the EU reveal highly variable concentrations of metals among samples from the …

Landscape Forcing Mechanisms On Quaternary Timescales: The Tabernas Basin, Se Spain, Martin Roy Geach
Landscape Forcing Mechanisms On Quaternary Timescales: The Tabernas Basin, Se Spain, Martin Roy Geach
School of Geography, Earth and Environmental Sciences Theses
Quaternary landform features and their associated sedimentary assemblages (river terraces and alluvial fans) often provide important records of long-term landscape evolution. The reconstruction of global terrace sequences has enabled the identification of numerous external and internal forcing mechanisms which operate within the Quaternary landscape system. The relative effects of these forcing mechanisms are highly variable over a range of spatial and temporal scales. In this research, a combined study approach is adopted in order to ascertain the significance of external (e.g. tectonics, climate) and/or internal (e.g. lithological thresholds) forcing mechanisms upon patterns of Quaternary landscape development within the Tabernas Basin, …
The Relationship Between Active Faulting And Fluvial Geomorphology: A Case Study In The Gediz Graben, Turkey., Emiko Jane Kent
The Relationship Between Active Faulting And Fluvial Geomorphology: A Case Study In The Gediz Graben, Turkey., Emiko Jane Kent
School of Geography, Earth and Environmental Sciences Theses
Identifying tectonically active faults and quantifying rates of movement is a key challenge in the Earth Sciences, in addition to this the interactions between active faulting and the landscape, specifically involving the fluvial network, is a relatively new area of study. Previous work has highlighted the value of understanding how the fluvial network responds to active tectonics, showing that a comprehensive understanding of the dynamic relationship between fluvial geomorphology and active tectonics is an important next step in geological research. This study presents new information about the poorly constrained Quaternary tectonic history of the Gediz Graben, Turkey, providing the first …
The Geomorphological Development Of Ephemeral And Relict River Valley Systems In The North Part Of The Iraqi Western Desert, Waleed Hamed
The Geomorphological Development Of Ephemeral And Relict River Valley Systems In The North Part Of The Iraqi Western Desert, Waleed Hamed
School of Geography, Earth and Environmental Sciences Theses
This research project provides a geomorphological and geological analysis of ephemeral and relict river valley systems in the north part of the Iraqi Western Desert. The area surveyed covers approximately 30 000 km2 and is one of the remotest and least studied parts of the Arabian Peninsula. Part of the reason for the lack of research in this area in recent years has been the ongoing security problems and all fieldwork undertaken for this thesis was carried out with the support of armed guards and police. In addition much of the work on the geology and geomorphology of the region …
Experiences Of Place And Change In Rural Landscapes: Three English Case Studies, Rebecca Wheeler
Experiences Of Place And Change In Rural Landscapes: Three English Case Studies, Rebecca Wheeler
School of Geography, Earth and Environmental Sciences Theses
This thesis examines how changes to rural places and landscapes are experienced by residents and incorporated into place attachments and identities over time. It does so through exploring findings from seventy-eight qualitative, ‘emplaced’, oral history interviews in three English villages: Mullion (Cornwall); Askam and Ireleth (Cumbria); and Martham (Norfolk). These villages are located near to at least one existing windfarm, which – as an example of rural change - provides a common focus for the research. The research is informed by a ‘middle-ground’ theoretical approach that considers discursive and experiential aspects of people-environment relationships and pays particular attention to how …
