title: Monitoring, understanding and modelling rainfall-runoff behaviour in two small residential urban catchments.
Creators: name: Redfern, TW
Publisher: name: University of Liverpool Repository
Year: 2018

description: Understanding the urban rainfall-runoff process is an important challenge for the hydrological sciences. Urban areas exhibit a complex mosaic of surface covers, ranging from those of an anthropogenic origin to surfaces of a disturbed natural form, which exhibit varying hydrological behaviours. The urban rainfall-runoff process is managed to reduce the risk of flooding within urban areas, whilst also considering the volume of runoff that downstream water bodies receive. Efforts to understand and manage the urban rainfall-runoff process are often hampered by a lack of rainfall runoff data of sufficient temporal (length and/or frequency) and spatial resolution for locations of interest. Therefore, urban rainfall-runoff processes are typically estimated using hydrological models that attempt to characterise the physical nature of urban areas (using assumptions and estimates of surface hydrological behaviour), that rarely consider how small-scale variations in urban surface cover and hydraulic connectivity influence rainfall-runoff behaviour. This thesis investigates how variations in the physical design, hydraulic form and age of two residential developments of north Swindon (Arley Close and Winsley Close) influence rainfall-runoff behaviour. Through high resolution monitoring of precipitation, drainage flows and soil moisture, a novel understanding of the complex rainfall-runoff properties of urban surface covers is developed, rejecting commonly applied, yet inaccurate assumptions regarding the total imperviousness of urban surfaces. The ability of engineering rainfall-runoff models to replicate the field study site results is assessed to develop an improved understanding of how variations in urban development patterns can be better represented within modelling tools. The implications of inaccurate rainfall-runoff modelling arising from the use of assumptions and estimates within the planning of a retro-fitted surface water drainage storage tank are assessed, demonstrating the importance of developing improved understanding of rainfall-runoff processes at small-scales within the urban environment.
Damage assessment, toughness modification and potential repair techniques of variable stiffness fibre-reinforced thermoplastic composite laminates
Creators: name: McLaughlin, John

Subjects: classificationCode: 40
subject: Engineering

description: Advancements in composite processing techniques, such as In-Situ Consolidation (ISC) for fibre-reinforced thermoplastics by Laser-Assisted Automatic Tape Placement (LATP), are enabling faster more efficient processing of advanced composite structures. In addition, automated tape laying systems allow steering of reinforcing fibres to produce variable stiffness laminates for enhanced structural performance,e.g., improved buckling, aeroelasticity, as well as allowing fibre steering around cut-outs to reduce stress concentrations. However, concerns about the vulnerability and repair of variable stiffness laminates is hindering their adoption. This thesis presents experimental work that investigated damage, toughness modifications, and potential repair techniques for conventional and variable stiffness Carbon Fibre-Reinforced Polyether Ether Ketone (CF/PEEK) laminates manufactured using LATP ISC.Damage of LATP ISC and autoclave consolidated CF/PEEK laminates was investigated using Non-Destructive Inspection (NDI) and destructive testing techniques. NDI, in the form of C-scans and dye-penetrant X-ray imaging, indicated a 36% larger internal damage area in impacted LATP ISC laminates compared to autoclave consolidated straight-fibre laminates. Compression After Impact (CAI) testing showed equivalent levels of strength retention, albeit the LATP ISC laminates had a 50% lowerinitial level of undamaged compressive strength. Variable stiffness laminates showed more extensive internal damage due to the laminates more compliant centre. However, variable stiffness laminates still exhibited higher loads prior to the onset of buckling in both damaged and undamaged states.Inspired by the fact that lower crystalline polymers have been shown to better sustain impact events, a unique approach to impact damage toughening was developed that involves interspersing amorphous Polyether Imide (PEI) film into a CF/PEEK laminate stacking sequence. This toughening technique produced laminates that were better able to withstand impact damage, as evidenced by the lower levels of internal damage observed, as well as the ability up to retain up to 47% more of its undamaged compressive strength at low impact energy levels.Finally, ultrasonic welding was investigated as a potential repair method for CF/PEEK laminates. Coupon level specimens were welded in both a standard single lap joint and a novel scarf joint configuration, their bond strength was assessed using tensile testing. Results indicated that this was a potentially viable joining method for patch repairs. However further work is required to improve the welding process and fixture design to achieve more consistent weld coverage, especially when utilising the scarf joint configuration.

description: We test whether there is a relation between the observed tidal interactions and Seyfert activity by imaging in HI twenty inactive galaxies at the same spatial resolution and detection threshold as the Seyfert sample. This control sample of inactive galaxies were closely matched in Hubble type, range in size and inclination, and have roughly comparable galaxy optical luminosity to the Seyfert galaxies. We find that only ~15% of the galaxies in our control sample are disturbed in HI, whereas the remaining ~85% show no disturbances whatsoever in HI. Even at a spatial resolution of ~10 kpc, none of the latter galaxies show appreciable HI disturbances reminiscent of tidal features. In a companion paper (Kuo et al. 2008), we report results from the first systematic imaging survey of Seyfert galaxies in atomic hydrogen (HI) gas. We find that only ~28% of the eighteen Seyfert galaxies in that sample are visibly disturbed in optical starlight. By contrast, ~94% of the same Seyfert galaxies are disturbed spatially and usually also kinematically in HI gas on galactic scales of >~20 kpc. In at least ~67% and up to perhaps ~94% of cases, the observed disturbances can be traced to tidal interactions with neighboring galaxies detected also in HI. The dramatic contrast between the observed prevalence of HI disturbances in the Seyfert and control samples implicates tidal interactions in initiating events that lead to luminous Seyfert activity in a large fraction of local disk galaxies.

Actin-related intercellular adhesion junctions in vertebrate Sertoli cells
Creators: name: Pfeiffer, David Carl
Publisher: name: University of British Columbia
Year: 2009

description: In the eutherian mammal seminiferous epithelium, the cytoplasm of Sertoli cells adjacent to certain regions of intercellular attachment exhibits unusual structural complexes. At these sites, a layer of non-contractile, hexagonally packed actin filaments is positioned between the Sertoli cell plasma membrane and an underlying cistern of endoplasmic reticulum. The filament layer along with the endoplasmic reticulum and the plasma membrane involved with attachment are referred to as an "ectoplasmic specialization". Ectoplasmic specializations are found apically at sites of attachment to spermatids and basally at sites of attachment to neighboring Sertoli cells. Similarly structured complexes are not found in other cell types nor in Sertoli cells of other vertebrate species. Ectoplasmic specializations of eutherian mammals have been hypothesized to be a highly specialized form of actin-related adhesion junction. If this is true, then non-mammalian homologues of this junction should be present and, in general, should more closely resemble typical actin-related adhesion junctions found in other cell types than do mammalian ectoplasmic specializations. I have tested this prediction by conducting a systematic comparative survey of the morphology and composition of actin-related adhesion junctions in Sertoli cells of non-mammalian vertebrates. My results indicate that vertebrate Sertoli cells use actin-related adhesion junctions as a common mechanism for adhesion to elongating spermatids and to neighboring Sertoli cells. In non-mammalian vertebrate classes, the junctions appear to possess contactile properties and, in general, more closely resemble the actin-related adhesion junctions of other cell types then do eutherian ectoplasmic specializations. Structural differences in the junctions between classes indicate that different strategies for intercellular adhesion have evolved at these sites within various vertebrate classes. These data suggest that eutherian mammal ectoplasmic specializations represent a modified form of actin-related adhesion junction. I speculate on what the precursors of the present-day eutherian junctions may have been like as well as on how and why structural adaptations may have occurred at these sites.

description: Radiofrequency emission in the 0.4 - 3 GHz range from FTU plasmas in presence of runaway electrons (RE) has been measured with unprecedentedly high time resolution. Rapid emission bursts associated with enhanced RE pitch angle scattering reveal kinetic instabilities affecting evolution of the RE population from the buildup phase. Such measurements also provide a sensitive monitor for instabilities during early RE formation. The leading edge of radio bursts is much shorter than interleaving periods of low emission; spectral broadening during growth indicates nonlinear wave coupling as an explanation for the observed intermittency. Radiofrequency emission disappears at the beginning of post-disruption RE plateaus, and subsequently reappears in the shape of very intense bursts accompanied by strong rises of suprathermal electron cyclotron emission.

Having in view the earliest historical testimonies, and comprising both nautical technical and more general maritime literature, we focus on the late medieval and early modern periods. Although we are aware of the inextricable relation between the studies of different aspects of Indian Ocean Arab navigation, and though we are surveying and profiting from a wide range of sources, our particular research within the ERC RUTTER Project gives a certain angle to our perspective: we are primarily concerned with the seamanship treatises (in Portuguese, livros de marinharia) by Arab authors, and how they were shared with or made their way into other nautical traditions. In this regard, we are fortunate to benefit from the extraordinary pool of knowledge of our colleagues at the Centro Interuniversitário de História das Ciências e da Tecnologia, Lisbon, and we offer a contribution which while not leaving historical stones unturned, is fully apprised with the living reality and practice of nautical sciences.
Gravitational waves from coalescing massive black holes in young dense clusters
Creators: name: Amaro-Seoane, Pau
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: HST observations reveal that young massive star clusters form in gas-rich environments like the Antennæ galaxy which will merge in collisional processes to form larger structures. These clusters amalgamate and if some of these clusters harbour a massive black hole in their centres, they can become a strong source of gravitational waves when they coalesce. In order to understand the dynamical processes that are into play in such a scenario, one has to carefully study the evolution of the merger of two of such young massive star clusters and more specifically their respective massive black holes. This will be a promising source of gravitational waves for both, LISA and the proposed Big Bang Observer (BBO), whose first purpose is to search for an inflation-generated gravitational waves background in the frequency range of $10^{-1}-1$ Hz. We used high-resolution direct summation $N-$body simulations to study the orbital evolution of two colliding globular clusters with different initial conditions. Even if the final eccentricity is almost negligible when entering the bandwidth, it will suffice to provide us with detailed information about these astrophysical events.

description: We present measurements of the temperature and power dependence of the resonance frequency and frequency noise of superconducting niobium thin-film coplanar waveguide resonators, carried out at temperatures well below the superconducting transition (T_{c}=9.2 K). The noise decreases by nearly two orders of magnitude as the temperature is increased from 120 to 1200 mK, while the variation of the resonance frequency with temperature over this range agrees well with the standard two-level system (TLS) model for amorphous dielectrics. These results support the hypothesis that TLS are responsible for the noise in superconducting microresonators, and have important implications for resonator applications such as qubits and photon detectors.

description: Starting with Carnot engine, the ideal efficiency of a heat engine has been associated with quasi-static transformations and vanishingly small output power. Here, we exactly calculate the thermodynamic properties of a isothermal heat engine, in which the working medium is a periodically driven underdamped harmonic oscillator, focusing instead on the opposite, anti-adiabatic limit, where the period of a cycle is the fastest time scale in the problem. We show that in that limit it is possible to approach the ideal energy conversion efficiency $η=1$, with finite output power and vanishingly small relative power fluctuations. The simultaneous realization of all the three desiderata of a heat engine is possible thanks to the breaking of time-reversal symmetry. We also show that non-Markovian dynamics can further improve the power-efficiency trade-off.

description: Polymer solutions subject to pressure driven flow and in nanoscale slit pores are systematically investigated using the dissipative particle dynamics approach. We investigated the effect of molecular weight, polymer concentration and flow rate on the profiles across the channel of the fluid and polymer velocities, polymers density, and the three components of the polymers radius of gyration. We found that the mean streaming fluid velocity decreases as the polymer molecular weight or/and polymer concentration is increased, and that the deviation of the velocity profile from the parabolic profile is accentuated with increase in polymer molecular weight or concentration. We also found that the distribution of polymers conformation is highly anisotropic and non-uniform across the channel. The polymer density profile is also found to be non-uniform, exhibiting a local minimum in the center-plane followed by two symmetric peaks. We found a migration of the polymer chains either from or towards the walls. For relatively long chains, as compared to the thickness of the slit, a migration towards the walls is observed. However, for relatively short chains, a migration away from the walls is observed.

Organizational injustice and its resistance using voice and silence
Creators: name: Harlos, Karen P.
Publisher: name: University of British Columbia
Year: 2009

description: This research is based on the premise that employees respond to dissatisfaction in general and organizational injustice in particular in two primary ways: by speaking up and/or by staying silent. This qualitative, theory-generating study examines the phenomenon of organizational injustice (including its antecedents and consequences) and employees' responses toward three research goals: 1) greater understanding of organizational injustice; 2) greater conceptual consensus through concept development of voice and silence; 3) a process model of organizational injustice, voice and silence. Also, new knowledge about voice and silence is linked to organizational practice by examining the availability of various voice systems and perceptions of their efficacy. The research design is influenced by several organizational research streams, as well as grounded theory and clinical methods. Thirty-two employees, each representing different organizations and occupying both managerial/professional positions and clerical/line positions participated in semi-structured, open-ended interviews in which they described 33 cases of workplace injustice. The interview design includes two methods: 1) a retrospective critical incident technique to discuss a workplace experience which participants defined as unjust; and 2) a projective exercise in which participants were asked to imagine that they could speak with impunity to the person(s) involved or responsible for their perceived injustice. Interview cases were supplemented by 30 archival cases of employees' voicing of discontent through a government-sponsored voice system. Significant results concerning the phenomenon of organizational injustice included the introduction of a four-category typology which departs from traditional classifications with its inclusion of interactional injustice (interpersonal mistreatment by a boss) as a distinct category, the systematic delineation and description of interactional injustice according to eight emergent behavioural dimensions, the identification of organizational antecedents to workplace injustice according to four emergent groupings (i.e., structural, procedural, cultural and global) and the identification of individual- and organizational-level consequences. In addition, the concepts of voice and silence emerged as forms of resistance to organizational injustice. Voice was found to encompass two distinct but related constructs: formal and informal voice. Specific strategies by which participants resisted injustice were identified for voice (formal and informal) and silence. A process model of voice and silence in organizational injustice was also introduced.

title: ROBUST HYDROLOGIC MODELLING FOR LAND AND WATER MANAGEMENT IN DATA-SCARCE ENVIRONMENTS
Creators: name: Tarawneh, E
Publisher: name: University of Liverpool Repository
Year: 2017

description: This study proposes a pre-calibration approach using the Soil and Water Assessment Tool (SWAT) to quantitatively assess variability in model performance derived from input data sources in data-scarce dryland environment (the Wala catchment, Jordan 1743 km2). Eighteen scenarios combining different local and global land-use, soil and weather datasets (1979 - 2002) are constructed. Model outputs are statistically assessed against observed discharge and empirically-derived sediment load using r2, Nash-Sutcliffe efficiency (NSE), root mean square error standard deviation ratio (RSR) and percent bias (PBIAS). Global reanalysis weather data considerably improve model performance over discontinuous local datasets, while detailed local soil data perform significantly better than global maps. The approach presented aids selection of the most robust input datasets in regions where availability and quality of data are questionable. Attempting to rationalise modelling in data-poor regions, the catchment delineation produced by the SWAT model is used to design field sampling in October 2013 of channel bed sediments and reservoir sediment cores to investigate potential relationships via geochemical analysis and provide measured sediment information that may interpret model prediction. XRF and particle size analyses were performed on all samples and the data analysed in respect of geochemical signatures. No strong evidence of discrete event-driven deposition is detected, likely due to alternating high-flood and drought periods. Variations in pollutants geochemistry are consistent with land-use pattern with relatively higher levels of Pb, Co, Cu and Cr associated with urbanised regions. Although these concentrations are mostly below thresholds for health concern, higher water and sediment loadings from these regions, as estimated by the model, may increase them. Hence, future management of water quality must be considered. The optimised and calibrated SWAT model is used to assess hypothetical and object-based integrated catchment management interventions and their implications for the useable lifetime of the Wala Dam within the context of the UN-funded BRP Project. The modelled catchment response to different scenarios varies spatially based on type and extent of application. Changes in annual loadings delivered to the Wala reservoir are linked to a simple model of dam functional lifetime to support decision-making.

description: The dynamics of wild populations are governed by demographic rates which vary spatially and/or temporally in response to environmental conditions. Conservation actions for widespread but declining populations could potentially exploit this variation to target locations (or years) in which rates are low, but only if consistent spatial or temporal variation in demographic rates occurs. Using long-term demographic data for wild birds across Europe, we show that productivity tends to vary between sites (consistently across years), while survival rates tend to vary between years (consistently across sites), and that spatial synchrony is more common in survival than productivity. Identifying the conditions associated with low demographic rates could therefore facilitate spatially targeted actions to improve productivity or (less feasibly) forecasting and temporally targeting actions to boost survival. Decomposing spatio-temporal variation in demography can thus be a powerful tool for informing conservation policy and for revealing appropriate scales for actions to influence demographic rates.
title: Transition to adulthood in England and Wales: The analysis of life trajectories of young adults
Creators: name: Pelikh, A

description: This thesis investigates various life trajectories of young people in England and Wales during the transition to adulthood. This thesis moves beyond one-event transitions and investigates education and employment, partnership, and residential careers from a longitudinal perspective. This thesis investigates how the trajectories are influenced by birth cohort, parental socio-economic background, and individual’s life course characteristics. This thesis investigates the cohorts born between 1974 and 1991 who experienced their transition to adulthood since the beginning of the 1990s. Overall, the longitudinal analysis of 5-year birth cohorts highlighted significant changes in life course trajectories over the last 25 years, while some continuity was observed as well. This thesis presents evidence towards “protracted” youth transitions with further postponement of leaving the parental home and first partnership formation, which can be partially explained by the expansion of further and higher education. Overall, the analysis suggests that together with the postponement, life course trajectories among the youngest cohorts have become more complex with a higher number of events occuring in all life domains (e.g. higher rates of moving and higher rates of separation from first cohabiting unions). Overall, the findings suggest that there is a trend towards a convergence in trajectories between men and women, although persistent inequalities are observed in labour market outcomes. Findings of this thesis provide evidence that parental socio-economic background which has traditionally played an important role in shaping young people's life course trajectories in Britain still explains a large part of the variation in transitions. Young people from more advantaged backgrounds are more likely to obtain high qualifications and profit from higher returns to longer time spent in education. Despite an increase in the proportion of young people from less advantaged backgrounds going into higher education, they are still much less likely to occupy professional and managerial positions. In contrast to previous arguments, parental socio-economic background was found to play little role in partnership transitions among the cohorts studied in this thesis.

description: We have improved the tree-level model of Ref arXiv:1004.5484 [hep-ph] for weak production of kaons off nucleons by partially restoring unitarity. This is achieved by imposing Watson's theorem to the dominant vector and axial-vector contributions in appropriate angular momentum and isospin quantum number sectors. The observable consequences of this procedure are investigated.

description: Electrocatalytic nanocarbon (EN) is a class of material receiving intense interest as a potential replacement for expensive, metal-based electrocatalysts for energy conversion and chemical production applications. The further development of EN will require an intricate knowledge of its catalytic behaviors, however, the true nature of their electrocatalytic activity remains elusive. This review highlights work that contributed valuable knowledge in the elucidation of EN catalytic mechanisms. Experimental evidence from spectroscopic studies and well-defined molecular models, along with the survey of computational studies, is summarized to document our current mechanistic understanding of EN-catalyzed oxygen, carbon dioxide and nitrogen electrochemistry. We hope this review will inspire future development of synthetic methods and in situ spectroscopic tools to make and study well-defined EN structures.
THE CONCEPT OF EGALITARIAN AND NON-EGALITARIAN SOCIETY

Publisher: name: Zenodo
Year: 2025

description: Abstract. This article will help you understand the concepts of egalitarian and non-egalitarian society as social systems and their approaches to justice and equality. An egalitarian society is a system based on the principles of equality and justice among all people, creating equal access to rights, opportunities, and resources for each individual. A non-egalitarian society, on the other hand, involves social inequality, where certain groups or individuals have more resources and power, which increases social division and injustice in society. This article will analyze the theoretical foundations, social and economic consequences of both types of society, as well as their practical manifestations. The article will contribute to a deeper exchange of ideas on the concepts of social systems and justice, and to a better understanding of the place of both systems in society.

description: Interaction of an electron with the counter-propagating electromagnetic wave is studied theoretically and with the particle-in-cell simulations in the regime of quantum radiation reaction. We find the electron energy in the center of the laser pulse, as it is a key factor for testing the non-linear quantum electrodynamics vacuum properties in the laser-electron collision in the regime of multi-photon Compton scattering and vacuum Cherenkov radiation. With multiparametric analysis we provide the conditions on electron initial energy for reaching the center of the laser pulse and emitting Cherenkov photons.

description: We investigate effects of lateral confinement on spin splitting of energy levels in 2D hole gases grown on [311] GaAs. We found that lateral confinement enhances anisotropy of spin splitting relative to the 2D gas for both confining directions. Unexpectedly, the effective $g$-factor does not depend on the 1D energy level number $N$ for $B\|[0\bar{1}1]$ while it has strong $N$-dependence for $B\|[\bar{2}33]$. Apart from quantitative difference in the spin splitting of energy levels for the two orthogonal confinement directions we also report qualitative differences in the appearance of spin-split plateaus, with non-quantized plateaus observed only for the confinement in $[0\bar{1}1]$ direction. In our samples we can clearly associate the difference with anisotropy of spin-orbit interactions.

description: This PDF includes data for all speakers who participated in the 2017 Nafaanra color naming data collection. A total of 10 Nafaanra speakers participated in the 2017 study. For 2 speakers (pgs 76-79; 80-83), participants responded strictly following the WCS protocol, meaning that only terms without a source could be given. However, participants struggled to provide any response for a large number of chips and were frustrated with the task. Therefore, for the remaining participants, a free response method was used, meaning speakers simply provided the color term they thought best suited the chip without emphasis on the WCS basic color terms. Data contain sheets contain both the data from the chip naming task and the focal color task.

description: Spin-resolved momentum microscopy and theoretical calculations are combined beyond the one-electron approximation to unveil the spin-dependent electronic structure of the interface formed between iron (Fe) and an ordered oxygen (O) atomic layer, and an adsorbate-induced enhancement of electronic correlations is found. It is demonstrated that this enhancement is responsible for a drastic narrowing of the Fe d-bands close to the Fermi energy (EF) and a reduction of the exchange splitting, which is not accounted for in the Stoner picture of ferromagnetism. In addition, correlation leads to a significant spin-dependent broadening of the electronic bands at higher binding energies and their merging with satellite features, which are manifestations of a pure many-electron behavior. Overall, adatom adsorption can be used to vary the material parameters of transition metal surfaces to access different intermediate electronic correlated regimes, which will otherwise not be accessible. The results show that the concepts developed to understand the physics and chemistry of adsorbate–metal interfaces, relevant for a variety of research areas, from spintronics to catalysis, need to be reconsidered with many-particle effects being of utmost importance. These may affect chemisorption energy, spin transport, magnetic order, and even play a key role in the emergence of ferromagnetism at interfaces between non-magnetic systems.

description: This report looks at trends in U.S. per capita consumption of total food, food at home, and food away from home using the latest data from annual surveys of urban household food spending for 1980 to 1988. Actual household spending was adjusted to 1988 food price levels to focus on consumption changes. Total food spending rose sharply for one-person households but declined steeply for households with six or more persons. Households headed by people 65 and over spent most on food at home and the least on food away from home.
