Decision-Making In The Selection Of Retrofit Facades For Non-Domestic Buildings, Helen Mary Garmston
Decision-Making In The Selection Of Retrofit Facades For Non-Domestic Buildings, Helen Mary Garmston
School of Art, Design and Architecture Theses
In the UK, boom periods of construction combined with typical building styles of the day, have resulted in a large stock of ageing office buildings at risk of structural vacancy and obsolescence. Despite their lack of insulation, high air infiltration, and solar gain, many such buildings from the 1960s-1970s are still in use today. Moreover, with UK buildings replaced at a rate of less than 2% a year, the majority of today's buildings will still be in use in 2050. Due to the impact of the facade on such aspects as thermal performance and aesthetics, façade retrofit is seen as …

Morphodynamics In The Lagos Lagoon: Observation And Inferences Of Change, Alfred Sunday Alademomi
School of Biological and Marine Sciences Theses
The focus of this research is the study of lagoon ecosystem interaction and adjustment of the lagoon floor morphologies, water dynamics and sequences of change involving the motion of sediment. The aim of the study is to implement a functional mechanism to evaluate and analyse changes in the Lagos Lagoon and its ecosystem, with the objectives: (i) to investigate the extent and impact of urban expansion on the Lagoon coastline and its ecosystem; (ii) to quantify changes in the spatial extent of mangroves by use of satellite images from 1984 to 2016; (iii) to investigate the spatial dynamics of the …
Modulation Of Innate Immune Cells By The Nad+ Pathway, Abbas Jawad Al-Shabany
Modulation Of Innate Immune Cells By The Nad+ Pathway, Abbas Jawad Al-Shabany
School of Biological and Marine Sciences Theses
NAD+ has previously been shown to regulate TNF-α synthesis and TNF-α has been shown to regulate NAD+ homeostasis, thus providing a link between a pro-inflammatory response and redox status. Despite the well-established link between TNF-α and NAD+, the mechanism as to how NAD+ modulates TNF-α release is not fully understood. To achieve this, this link was investigated using THP-1 cell line-derived M1-like (pro-inflammatory) and M2-like (anti-inflammatory) macrophages using PMA and vitamin D3, respectively. NAD+ levels differed markedly between M1-like and M2-like macrophages, with M1-like having much higher basal levels. LPS increases NAD+ levels and TNF-α secretion in M1-like but not …
Application Of An Improved Video-Based Depth Inversion Technique To A Macrotidal Sandy Beach, Erwin Willem Johan Bergsma
Application Of An Improved Video-Based Depth Inversion Technique To A Macrotidal Sandy Beach, Erwin Willem Johan Bergsma
School of Biological and Marine Sciences Theses
Storm conditions are considered the dominating erosional mechanism for the coastal zone. Morphological changes during storms are hard to measure due to energetic environmental conditions. Surveys are therefore mostly executed right after a storm on a local scale over a single or few storms [days to weeks]. The impact of a single storm might depend on the preceding sequence of storms. Here, a video camera system is deployed in the South-West of England at the beach of Porthtowan to observe and assess short-term storm impact and long-term recovery. The morphological change is observed with a state-of-the-art video-based depth estimation tool …
The Biological And Ecological Impacts Of Hypoxia On Coastal Benthic Communities, Ruth Naomi Calder-Potts
The Biological And Ecological Impacts Of Hypoxia On Coastal Benthic Communities, Ruth Naomi Calder-Potts
School of Biological and Marine Sciences Theses
Traditionally, hypoxia has been defined as the situation where DO levels have fallen below 2.0 mg O2 L-1, but increasing evidence suggests that this low level of DO is inadequate to describe the onset of hypoxia impacts for many organisms. Consequently, there is a need for a greater understanding of how ‘moderate’ alterations in DO levels will affect ecosystem processes and functionality, specifically through behavioural and physiological alterations at the organism and community level. This thesis reports on mesocosm experiments which were conducted to examine the effects of moderate (> 3.0 mg O2 L-1) hypoxia on firstly, a key ecosystem …
Spatial And Temporal Variability Of Sandy Beach Sediment Grain Size And Sorting, Sam Prodger
Spatial And Temporal Variability Of Sandy Beach Sediment Grain Size And Sorting, Sam Prodger
School of Biological and Marine Sciences Theses
Beach grain size plays a major role in controlling beach slope and sediment transport rates and is a crucial criterion in selecting the appropriate fill material for beach nourishment. Yet, little is known about how and why beach grain size (and sorting) varies both spatially and temporally on high-energy sandy beaches. Therefore, in this PhD research project, the presence, magnitude and predictability of any spatio-temporal sediment variability was investigated on a number of contrasting high-energy (average significant wave height = 0.8 to 3.5 m), predominantly macrotidal (MSR = 3.1 – 6.2 m), sandy (0.26 – 0.64 mm) beach sites around …
The Vulnerability Of Different Populations Of The Commercially-Important Shrimp Pandalus Borealis To Environmental Stress, Emilie Florence Hall
The Vulnerability Of Different Populations Of The Commercially-Important Shrimp Pandalus Borealis To Environmental Stress, Emilie Florence Hall
School of Biological and Marine Sciences Theses
The present study adopted an integrative approach to conduct a population comparison of vulnerability to environmental stress in a commercially important species of ectotherm. Specifically, I investigated how differing environmental conditions in native habitats may drive intra-species divergence and alter performance when conditions shift. This study used northern prawn (Pandalus borealis Krøyer 1838) populations with known morphological differences from two spatially proximate fjord sites differing in oxygen regime as a model system. The genetic population structure was analysed and whole organism, physiological, and metabolomic performance under hypoxia and thermal stress were assessed. Genetic analyses displayed no significant dissimilarities between P. …
The Microbiological Safety Of Fresh Produce In Lebanon- A Holistic “Farm-To-Fork Chain” Approach To Evaluate Food Safety, Compliance Levels And Underlying Risk Factors, Dima Faour-Klingbeil
The Microbiological Safety Of Fresh Produce In Lebanon- A Holistic “Farm-To-Fork Chain” Approach To Evaluate Food Safety, Compliance Levels And Underlying Risk Factors, Dima Faour-Klingbeil
School of Biological and Marine Sciences Theses
The consumption of unsafe fresh vegetables has been linked to an increasing number of outbreaks of human infections. In Lebanon, although raw vegetables are major constituents of the national cuisine, studies on the safety of fresh produce are scant. This research employed a holistic approach to identify the different stages of the food chain that contribute to the microbiological risks on fresh produce and the spreading of hazards. A thorough analysis of the institutional and regulatory framework and the socio-political environment showed that the safety of local fresh produce in Lebanon is at risk due to largely unregulated practices and …
Field Observations Of Infragravity Wave Response To Variable Sea-Swell Wave Forcing, Kris William Inch
Field Observations Of Infragravity Wave Response To Variable Sea-Swell Wave Forcing, Kris William Inch
School of Biological and Marine Sciences Theses
Infragravity waves are low frequency (0.005-0.04 Hz) waves that can dominate the spectrum of water motions and sediment transport processes within the inner surf zone. Despite the established importance of infragravity waves in shaping our coasts and numerous studies dating back to the 1950s, several aspects of infragravity wave analysis, generation and dissipation remain poorly understood. As much of the recent infragravity research has focussed on fetch-limited coasts, less is known about the climatology of these waves on energetic coastlines subject to both swell and fetch-limited waves. It has been postulated that bed friction only plays a significant role in …
Academic Capitalism In Architecture Schools: A Feminist Critique Of Employability, 24/7 Work And Entrepreneurship, I Troiani
School of Art, Design and Architecture
This chapter examines the current situation that many universities worldwide are facing due to globalisation, which is of transitioning from institutions for education (Foucault’s ‘premodern or medieval university’) toentrepreneurial businesses (the ‘modern university’). The modern university is governed by a neoliberal system of production and consumption of students, staff, knowledge and research for the purpose of improving nation economies. Looking particularly at schools of architecture, it discusses employability, 24-hour work and entrepreneurship in relation to marketisation and economisation. It tracks the inequalities that arise from the neoliberalisation of public universities on teaching content, an administrative-directed work, workloads, wellbeing and gender. …

Novel Use Of Field-Portable-Xrf For The Direct Analysis Of Trace Elements In Marine Macroalgae., Annie Bull, Murray T. Brown, Andrew Turner
School of Geography, Earth and Environmental Sciences
Samples of dried marine macroalgae (Fucus serratus, Palmaria palmata and Ulva lactuca) have been analysed for trace elements by a novel, non-destructive approach involving a Niton field-portable-X-ray fluorescence (FP-XRF) spectrometer configured in a low density plastics mode with thickness correction. Detection limits for a 200-s counting time ranged from <5 μg g(-1) for As and Pb in F. serratus and As in P. palmata to several tens of μg g(-1) for Cd, Sb and Sn in all species tested. Arsenic, Cu, Pb and Zn were detected by the XRF in samples collected from a protected beach (n = 18) and in samples therefrom that had been exposed to additional aqueous elements in combination (n = 72) with concentrations returned (in μg g(-1)) ranging from 3.9 to 39.7 for As, 13.0 to 307 for Cu, 6.1 to 14.7 for Pb and 12.5 to 522 for Zn. Independent measurements of trace elements in the macroalgae by ICP-MS following nitric acid digestion revealed a direct and significant proportionality with concentrations returned by the XRF, with slopes of the XRF-ICP relationships (As = 1.0; Cu = 2.3; Pb = 2.4; Zn = 1.7) that can be used to calibrate the instrument for direct measurements. The approach shows potential for the in situ monitoring of macroalgae in coastal regions that is currently being investigated.

This Is Where We Are - Collectively Living, Working And Being, With And Through Predictive Algorithms., B Aga, M Phillips
School of Art, Design and Architecture
‘This Is Where We Are’ (TIWWA) was an immersive and interactive algorithmic sculpture fuelled by the data we collectively generate. This collaborative work was created for the opening of the new Tate Modern Switch house in London in June 2016 by the i-DAT Research and Design Collective, Tate Collective London and Intercity. This technological fusion of interactive light and sound asked audiences to consider the data they generate and the algorithmic systems that increasingly mediate their reality and influence their behaviour. The creation of the sculptural artefacts and the digital systems driving them, were forged through interplay between data, algorithms …

Social Geology — Integrating Sustainability Concepts Into Earth Sciences, Iain S. Stewart, Joel C. Gill
Social Geology — Integrating Sustainability Concepts Into Earth Sciences, Iain S. Stewart, Joel C. Gill
School of Geography, Earth and Environmental Sciences
Most geologists would argue that geoscientific knowledge, experience, and guidance is critical for addressing many of society's most acute environmental challenges, yet few geologists are directly engaged in current discourses around sustainable development. That is surprising given that several attributes make modern geoscience well placed to make critical contributions to contemporary sustainability thinking. Here, we argue that if geoscientists are to make our know-how relevant to sustainability science, two aspects seem clear. Firstly, the geoscience community needs to substantially broaden its constituency, not only forging interdisciplinary links with other environmental disciplines but also drawing from the human and behavioral sciences. …

A Sense Of The Cycling Environment: Felt Experiences Of Infrastructure And Atmospheres, Paul Simpson
A Sense Of The Cycling Environment: Felt Experiences Of Infrastructure And Atmospheres, Paul Simpson
School of Geography, Earth and Environmental Sciences
This paper explores how cyclists gain a sense of the environments they move through by considering their felt experiences of the affective atmospheres that emerge in and through their movements. More specifically, the focus falls upon how various forms of transport infrastructure choreograph bodies in their movements through the city and so contributes towards the co-production of various affective atmospheres between differently mobile bodies. Drawing on video interviews with 24 commuter cyclists in Plymouth, UK, the roles that such infrastructures and atmospheres play in shaping the experience of cycling through shared forms of transport space are considered. Based on this, …
