title: The Sumatra subduction zone: seismicity, velocity structure and seismic anisotropy
Creators: name: Collings, Rachel
Publisher: name: University of Liverpool Repository
Year: 2014

description: On September 12 2007, an Mw 8.4 earthquake occurred within the southern section of the Mentawai segment of the Sumatra subduction zone, where the subduction thrust had previously ruptured in 1833 and 1797. Following the 2007 rupture, a temporary local network was installed in the Mentawai region between December 2007 and October 2008 to record the aftershocks. Additionally, a second network was installed in central Sumatra between April 2008 and February 2009. In this study the data obtained from the Mentawai network were used to determine 2D and 3D Vp and Vp/Vs models, first motion polarity focal mechanisms and accurate hypocentre locations. In addition to this, shear wave splitting (SWS) measurements from both networks were used to determine the type, amount and location of anisotropy. This has enabled us to obtain a detailed image of the structure of the subduction zone, ascertain the down-dip limit of the seismogenic zone and determine the deformation occurring. The forearc islands are characterized by a low Vp (4.5-5.8 km/s) and a high Vp/Vs ratio (>2.0), suggesting that they consist of fluid-saturated sediments. The down-going slab is clearly distinguished by a dipping region of high Vp (8.0 km/s), which can be traced to ~50 km depth, with an increased Vp/Vs ratio (1.75 to 1.90) beneath the forearc islands and the western side of the forearc basin, suggesting hydrated oceanic crust. Beneath the slab, a ~150 km thick layer of sub-slab anisotropy has developed due to the oceanic asthenosphere being entrained by the subducting slab. Two clusters of seismic activity are found within the ~25-30 km thick overriding crust. The location of the first cluster confirms that the Mentawai Fault is active and may accommodate backthrust movement, while the second cluster suggests a backthrust may be present on the eastern side of the forearc basin. Local SWS measurements suggest that in the overriding plate, adjacent to the Sumatran Fault, a layer of anisotropy has formed from fault-parallel aligned fractures and minerals. Beneath the forearc, a shallow continental Moho of

description: Acute respiratory infections (ARI) are the leading cause of mortality in children under five years of age worldwide and most of these deaths are due to bronchiolitis and pneumonia. Recent evidence from studies using genome detection systems such as polymerase chain reaction or micro-array technology show that, in most cases, these deaths are caused or precipitated by viruses. In this paper, the definitions of upper and lower respiratory tract infections are reviewed. The principal signs of disease severity and the burden of viruses as causes of ARI are described. The prominent role of Respiratory Syncytial Virus is stressed, with data from epidemiological and clinical studies. Other important viral pathogens, such as Human Metapneumovirus, Human coronaviruses and Influenza are examined. The role of newly described viruses, such as bocavirus, is also discussed. The impact of HIV/AIDS in ARI burden and presentation assessed and the weight of Pneumocystis jiroveci and Mycobacterium tuberculosis infections is recognized. It is concluded that there is an urgent need to improve diagnostics, therapeutics and vaccines, as well as macro and micronutrient intake of children of the world, particularly in developing countries.

title: Involving the reader in the text: engagement markers in native and non-native student argumentative essays
Creators: name: Rasti, Iman
Publisher: name: University of Liverpool Repository
Year: 2012

description: The research explores an aspect of writer-reader interaction in native and non-native speaker student argumentative essays. Based on the assumption that writing is inherently a dialogue between writers and readers, this study looks in detail at key aspects of the ways in which Iranian and British students interact with their readers, bring them into the text, and involve them in the construction of the discourse and the arguments in order to contribute to the interactiveness and persuasiveness of the text. Three linguistic resources – interactant pronouns, questions, and directives – are looked at in a corpus totalling 334 short argumentative essays produced by Iranian EFL writers (at two proficiency levels of high and low and two test versions of Academic and General) and British A-level students. The texts are analyzed using specially devised analytical frameworks and with the help of WordSmith Tools, a corpus analysis software. The results reveal that both language groups use the three linguistic devices for fairly similar purposes, indicating the generic similarities in the writings of both groups of students. The findings, however, show noticeable quantitative differences: the British students use questions more frequently than the Iranian students, whereas the Iranian students use interactant pronouns and directives considerably more frequently than the British students. The quantitative differences seem to be related to distinct cultural conventions as well as the Iranians’ overall lower proficiency level. Within the Iranian sub-corpora, Iranian high-scoring and Iranian Academic students use the three interactive resources more frequently than their low-scoring and General counterparts. The pedagogical implications of the study for novice EFL writers are outlined.

description: This systematic review and meta-analysis aims to systematically review the fatty acid (FA) composition of breast milk in different populations. We systematically searched the Medline via PubMed, Scopus and Clarivate till July 2019. We initially retrieved 433 articles. Having removed duplicates, with initial searching of title and abstracts, 317 papers were excluded and 80 remained. A meta-analysis of 80 cross-sectional, cohort studies, including 8793 subjects, was conducted. Meta-regression analysis indicated that factors including maternal age (p-values of SFA: 0.03, omega-3: 0.01, trans fats:<0.001, total fatty acids: 0.02), year of conducting study (p-values of SFA: <0.001, MUFA: 0.02, omega-6: 0.04,trans fats: 0.04) and sample size (p-values of SFA: 0.03, PUFA: 0.01, omega-6: 0.01, omega-3:<0.001) contributed to the heterogeneity of meta-analysis. This study indicates the large variation of FA content in maternal milk across different populations. Special concern is necessary for both the quality and total amount of fat intake of pregnant and lactating mothers.

description: We implement an efficient strong-disorder renormalization-group (SDRG) procedure to study disordered tight-binding models in any dimension and on the Erdos-Renyi random graphs, which represent an appropriate infinite dimensional limit. Our SDRG algorithm is based on a judicious elimination of most (irrelevant) new bonds generated under RG. It yields excellent agreement with exact numerical results for universal properties at the critical point without significant increase of computer time, and confirm that, for Anderson localization, the upper critical dimension duc = infinite. We find excellent convergence of the relevant 1/d expansion down to d=2, in contrast to the conventional 2+epsilon expansion, which has little to say about what happens in any d>3. We show that the mysterious mirror symmetry of the conductance scaling function is a genuine strong-coupling effect, as speculated in early work. This opens an efficient avenue to explore the critical properties of Anderson transition in the strong-coupling limit in high dimensions.

description: Sports performance is the result of a complex interaction between individual and environmental factors. The purpose of this paper is to explain the methods used in the InTrack Project, a cross-sectional and cross-cultural project developed to investigate the variance in the performance of runners from different countries and to understand whether the differences in the performance can be explained by micro-level (athletes characteristics and proximal environment), meso-level (the distal environment that plays a relevant role on the relation?ships established at micro-level), and the macro-level (environmental features that shape countries characteristics). The sample will be comprised of runners, of both sexes, from four countries. Data collection will be performed in two steps: i) Individual information and ii) Country-level information. At the individual level, data will be obtained from an online survey. At the country level, characteristics data will be obtained from the secondary data available (demographic, social, and economic variables). Statistical procedures expected to be used include multilevel analysis, latent class analysis, addictive and multiplicative interaction in regression models. This wealth of information is of relevance to fill gaps regarding the existence of variables to connect different levels of information, and to provide scientific support about environmental characteristics important to predict runners’ performance within and between countries.

title: Do systematic reviews and meta-analyses, published in the dental literature, comply with the QUOROM and PRISMA statements?
Creators: name: Al-Ramadhan, Noor
Publisher: name: University of Liverpool Repository
Year: 2012

description: Background: The QUOROM and PRISMA guidelines were created in an attempt to improve the standard of reporting systematic reviews. At present there are no studies in the dental literature that have assessed the compliance of papers with these two sets of guidelines. Aims: To determine whether the reports of systematic reviews in four dental specialities comply with the QUOROM and PRISMA statements, whether there has been an improvement in standard over time and whether Cochrane reviews differ from other reviews. Design: Retrospective observational study Method: A search of the Cochrane library identified 181 systematic reviews and meta-analyses for inclusion across four dental specialities (orthodontics, periodontics, preventive dentistry and endodontics). Each review was scored using a 63-item checklist developed from the QUOROM guidelines and a 63-item checklist developed from the PRISMA guidelines. Results: The mean QUOROM score for the whole sample was 70.86% (SD 11.36%, 95% CI 69.20%, 70.86%) and the mean PRISMA score for the whole sample was 74.07% (SD 10.48%, 95% CI 72.53%, 75.61%). The mean PRISMA score for Cochrane reviews was 85.19% (SD 5.03%, 95% CI 83.79%, 86.59%) and the mean PRISMA score for non-Cochrane reviews was 69.59% (SD 8.60%, 95% CI 68.09%, 71.09%). This difference was statistically significant (mean difference 15.50% (95% CI 13.58%, 17.62%; p
title: A cross-sectional paediatric pilot study of migraine, eating behaviours and adiposity
Creators: name: Singh, Shashi
Publisher: name: University of Liverpool Repository
Year: 2012

description: Objective The primary aim was to compare eating behaviours between migraine cases and non-migraine headache controls. The secondary aim was to assess the relationship migraine severity and monthly headache frequency share with eating behaviours, food intake, food cravings and adiposity among migraine cases. Background Recent research has highlighted an association between migraine and adiposity, in adults and children. However the direction of causality between migraine and adiposity has not yet been established. There are overlapping neurobiological mechanisms in migraine, eating behaviours and adiposity. Migraine has been noted to affect appetite, but this has not been formally studied. This pilot study explored the biologically plausible hypothesis that migraine may lead to obesity, via alterations in appetite, food intake and food cravings. Methods A single-centre, cross-sectional, questionnaire-based, clinical migraine population pilot study was designed. The two migraine measures were migraine severity as measured by the PedMIDAS tool and monthly headache frequency. Eating behaviours were assessed using the Dutch Eating Behaviour Questionnaire (DEBQ) and Child Eating Behaviour Questionnaire (CEBQ). Food cravings were measured by the Food Craving Inventory (FCI-II) and food intake was assessed using the Food Intake Questionnaire (FIQ). Adiposity was indirectly measured using BMI z-scores. Local Research Ethics and Trust R&D approvals were granted in June 2009. Results Sixty children aged 5-17 years were recruited from neurology/general paediatric clinics. Insufficient control patients were recruited (n=7). The desire to drink subscale of the CEBQ had a significant positive correlation with the PedMIDAS scores (rs= 0.41, p= 0.01). Monthly headache frequency had a significant positive correlation with the negative marker food scores of the FIQ (rs= 0.27, p= 0.04). Conclusion The primary objective to compare eating behaviours between migraine cases and non-migraine headache controls was not achieved. Migraine severity (as measured by the PedMIDAS scores) is weakly associated with the desire to drink (as measured by the CEBQ). Monthly headache frequency is weakly associated with the intake of unhealthy foods eaten the day before. It must be noted there is only weak evidence for the conclusions given the small sample size of this pilot study.
title: Mixing in the continental slope: study case Gulf of Cadiz
Creators: name: Alvarado Bustos, Ruben
Publisher: name: University of Liverpool Repository
Year: 2011

description: Internal waves in the ocean are the principal generators of mixing in the abyssal ocean and regions of rough topography. The present research work diagnoses the influence of internal wave activity over the Continental slope in the Gulf of Cadiz. Mediterranean Outflow (MOW) and North Atlantic Central Water (NACW) are the main baroclinic flows over the study region and diapycnal mixing acts in each layer. Semi-diurnal internal tides and a continuous MOW flow are observed on the slope. The MOW flow is persistent reaching >0.40 ms-1, but varies in strength with the tides. The Internal wave field in the Gulf of Cadiz can play an important role affecting the MOW signal over the continental slope; MOW can be displaced by the internal tide. Internal waves are generated by tides and MOW flow interacting with the bottom, the two most energetic sources locally. Also MOW bottom stress provides strong diapycnal mixing, providing well-mixed conditions in the MOW. Internal tides can transfer energy on the slope and can cause turbulence. A critical slope characteristic for semidiurnal internal waves occurs over the continental slope with local background stratification where MOW travels as an undercurrent. Diapycnal mixing is found to be enhanced inside the MOW with a diapycnal diffusivity O(7x10-4 m2s-1), and at the MOW-NACW interfaces, reaching O(2x10-4 m2s-1) for the upper interface and O(5x10-4 m2s-1) for the lower interface. Fine-structure methods are used to estimate mixing using CTD measurements; however most of the records came from temperature profiles (XBTs) and an alternative approach to diagnose the strain uses temperature profiles with inferred salinity (using temperature-salinity relations from the CTDs). Applying the strain method using temperature with inferred salinity profiles provides a plausible approximation of the strain spectrum and the mixing estimates, with uncertainties similar to those diagnosed using CTD measurements. Mixing estimates are also diagnosed using a large scale box model, where a salinity budget is applied to study gain and loss over the Gulf of Cadiz. Box model results confirm that salinity is diapycnally transferred from the MOW layers into the neighbouring NACW layers. The advective and diffusive transfers of salt along the layer are much larger than the diapycnal transfer. The inferred diffusivities from the box model are broadly in accord with the estimates from strain.
title: Investigation of the importance of individual members of the Nuclear Factor-κB family during Helicobacter felis induced gastric carcinogenesis
Creators: name: Burkitt, Michael
Publisher: name: University of Liverpool Repository
Year: 2012

description: Gastric cancer is the final outcome of a well-defined process of inflammation, remodelling of the gastric mucosal architecture and finally carcinogenesis. In humans, the trigger to develop gastric epithelial inflammation is infection with Helicobacter pylori. Whilst the pathological progression following Helicobacter infection has been well described, the reasons why some individuals progress towards gastric carcinogenesis, whilst others do not, remain relatively poorly understood. Previous studies in transgenic mice have demonstrated an association between classical pathway NF-κB signalling and Helicobacter induced gastric pathology. However the roles of specific NF-κB family members and of alternative pathway NF-κB signalling have not previously been investigated. We hypothesised that individual NF-κB proteins would play specific roles in determining the onset of Helicobacter induced gastric pathology, and that these pathways may influence the eventual outcome of Helicobacter infection. To address these hypotheses we used transgenic mice with constitutive deletions of NF-κB1, NF-κB2 and c-Rel, along with the established H. felis model of murine gastric cancer. Animals were studied at 6 and 48 weeks post infection. NF-κB1 null mice developed gastric inflammation and atrophy even without infection when aged to 1 year. These animals also developed more advanced gastric atrophy and metaplasia when infected with Helicobacter felis for 1 year. c-Rel null mice demonstrated similar epithelial pathology to wild-type mice, but following long-term infections developed significant atypia in infiltrating lymphoid cells, in keeping with c-Rel playing a role in gastric lymphomagenesis. In contrast NF-κB2 null mice developed minimal pathology at both 6 and 48 weeks following infection, and hence appear to be resistant to gastric corpus atrophy in response to Helicobacter felis infection. These findings confirm the previously known role for classical pathway NF-κB signalling in epithelial cancers, and suggest that this is an NF-κB1 specific effect, rather than being mediated by c-Rel. We provide the first description of c-Rel null mice showing enhanced gastric lymphomagenesis, and also describe profound resistance to Helicobacter induced gastric pathology in mice with abrogated alternative pathway NF-κB signalling, a pathway that has not previously been investigated in studies of epithelial carcinogenesis.

description: We generalise the hyperplane separation technique (Chatterjee and Velner, 2013) from multi-dimensional mean-payoff to energy games, and achieve an algorithm for solving the latter whose running time is exponential only in the dimension, but not in the number of vertices of the game graph. This answers an open question whether energy games with arbitrary initial credit can be solved in pseudo-polynomial time for fixed dimensions 3 or larger (Chaloupka, 2013). It also improves the complexity of solving multi-dimensional energy games with given initial credit from non-elementary (Brázdil, Jančar, and Kučera, 2010) to 2EXPTIME, thus establishing their 2EXPTIME-completeness.

description: Modern hardware architectures are increasingly parallel, through both massively multicore CPUs and accelerators which often dominate the available compute on the newest nodes. Utilizing this hardware fully is increasingly difficult with traditional programming models. At the same time the hardware landscape has further diversified which increases the burden on application developers to run their applications anywhere. HPX, a tasking runtime with a focus on distributed applications and standards conformance, is ideally suited to tackle the first challenge. Kokkos, a performance portability layer, handles the second. However, using them together has not been straightforward until the integrations presented here. This talk presents the integration of HPX and Kokkos on multiple different levels with: 1. an HPX backend for Kokkos, which is the first asynchronous CPU backend for Kokkos; 2. HPX-Kokkos, a thin interoperability layer which combines primitives provided by HPX and Kokkos; and 3. The integration of all of the former into Octo-Tiger, an astrophysics application. The integration allows applications to make full use of the portability provided by Kokkos and move past the limitations of fork-join parallelism with the tasking provided by HPX. Finally, this talk will present the latest integration of the C++ std::execution proposal for asynchrony into HPX and Kokkos, and how it provides a path towards a standardized solution for portability and asynchrony in applications like Octo-Tiger.

title: CdTe nanowire structures for solar cells
Creators: name: Williams, Benjamin Luke
Publisher: name: University of Liverpool Repository

description: This thesis investigates the growth and characterisation of CdTe and core-double shell ITO/CdS/CdTe nanowires (NWs), ITO/ZnO/CdS/CdTe/Mo thin-film solar cells and ITO/ZnO/CdS/CdTe(NW)/CdTe/Mo core-triple shell NW solar cells. First, the generation of Au-catalysed CdTe NWs arrays on Mo foils is reported, with CdTe being deposited by close-space sublimation. NWs were up to 20 μm long, had diameters in the range 5 – 500 nm and densities in the range 106 – 107 cm-2. A vapour-liquid-solid mechanism of NW growth, mediated by a Au-Te liquid catalyst, which accounts for the initial delay to NW nucleation (and the observed film growth) is postulated. By fitting a theoretical model of NW growth to experimental NW radius-time data, values for the sidewall diffusion length (2 μm) and sticking probability (0.61) were obtained. NW growth was also achieved on CdTe/Mo, with higher NW densities (108 cm-2) achieved compared to growth directly on Mo. NW defects were evaluated by TEM and photoluminescence (PL). TEM analysis showed low-energy Σ = 3 grain boundaries present in the NWs, their incidence being dependent on the growth axis, which was either , or . No high energy grain boundaries were observed. Their low-temperature PL spectra were dominated by excitonic emission with rarely observed above-gap emission also being recorded. PL also provided evidence of a deep level due to Au. UV-VIS-IR measurements showed that above-gap reflectance of NW arrays (~ 0.1%) was lower than for films of equivalent material (~ 10%). Methods of coating the NWs with conformal CdS and ITO shells were explored, with RF sputtering proving most suitable. HRTEM imaging demonstrated that the CdS/CdTe interface was epitaxial, the quality of the core-shell interface being thought to be critical for NW solar cells. Low temperature PL spectra of CdS/CdTe NWs showed CdS luminescence typical of single-crystal material and also implied that interdiffusion at the core-shell interface occurred. Above-gap reflectance for core-double shell ITO/CdS/CdTe NWs was ~ 0.1%. The fabrication procedures for thin-film CdTe devices on Mo foils were investigated so that understanding could be transferred to NW device fabrication. For thin-film devices, a peak efficiency of 8.0% was achieved upon incorporation of a double-anneal treatment process and a highly-resistive transparent ZnO layer. The main limitation to performance was the rectifying back contact, having a barrier height of = 0.51 eV. Methods to improve the quality of the contact are suggested based on device modelling. Simulations comparing the operation of thin-film and NW solar cells predict that when minority carrier diffusion lengths are short (
Explaining Low Energy $γ$-ray Excess from the Galactic Centre using a Two Component Dark Matter Model

description: Over the past few years, there has been a hint of the $γ$-ray excess observed by the Fermi-LAT satellite borne telescope from the regions surrounding the Galactic Centre at an energy range $\sim 1$-$3$ GeV. The nature of this excess $γ$-ray spectrum is found to be consistent with the $γ$-ray emission expected from dark matter annihilation at the Galactic Centre while disfavouring other known astrophysical sources as the possible origin of this phenomena. It is also reported that the spectrum and morphology of this excess $γ$-rays can well be explained by the dark matter particles having mass in the range $30\sim 40$ GeV annihilating significantly into ${\rm b} \bar{\rm b}$ final state with an annihilation cross section $σ{\rm v}\sim (1.4$ - $2.0)\times 10^{-26}$ cm$^3/$s at the Galactic Centre. In this work, we propose a two component dark matter model where two different types of dark matter particles namely a complex scalar and a Dirac fermion are considered. The stability of both the dark sector particles are maintained by virtue of an additional local U$(1)_{\rm X}$ gauge symmetry. We find that our proposed scenario can provide a viable explanation for this anomalous excess $γ$-rays besides satisfying all the existing relevant theoretical as well as experimental and observational bounds from LHC, PLANCK and LUX collaborations. The allowed range of "effective annihilation cross section" of lighter dark matter particle for the ${\rm b} \bar{\rm b}$ annihilation channel thus obtained, is finally compared with the limits reported by the Fermi-LAT and DES collaborations using data from various dwarf spheroidal galaxies.
description: 11 eps figures, 2 tables, 42 pages. Additional constraints on Z' from EWPD and LHC results are considered, two new annihilation channels of \psi and S are introduced, upper limits on dark matter annihilation cross sections from various dwarf spheroidal galaxies are also considered, new references added, basic results remain unchanged.

description: Articular chondrocytes reside in a unique and challenging avascular environment in cartilage. During joint disease, O2 and pH levels are further reduced, and may be involved in chondrocyte dysfunction and cartilage matrix breakdown. How fluctuations in these environmental parameters affect factors such as redox balance and mitochondrial function in articular chondrocytes is largely unknown but may provide a link between the extracellular environment to cell signalling pathways that may alter cellular and hence cartilage integrity. Additionally, ROS-regulatory compounds may offer scope for therapeutic intervention in joint disease. In this project, the effects of different O2 levels (
title: Design and synthesis of bi-functional, 1,2,4,5-tetraoxane-based molecular wires and their application in microbial fuel cells
Creators: name: Zhou, Katy
Publisher: name: University of Liverpool Repository
Year: 2014

description: Chapter 1 begins with a general introduction to the main aspects of this work: Firstly, a species of electrogenic bacteria, Geobacter sulfurreducens is introduced. Their ability to take part in extracellular electron transfer, the mechanisms by which this happens, and their involvement in electricity generation and bioremediation when applied in microbial fuel cells is discussed; Secondly, microbial fuel cells (MFCs) as an alternative method of electricity generation to fossil fuels, their methods of operation and their potential for use in the treatment of wastewater is briefly reviewed; Finally, antimalarial drugs (including their semi-synthetic and synthetic analogues) and their mechanisms of action are presented. The possibility of exploiting them as a template for bi-functional molecular wires that are capable of tethering bacteria to carbon and/or gold electrode surfaces is discussed in detail. Chapter 2 outlines our efforts towards novel analogues of synthetic antimalarials, dispiro-1,2,4-trioxolanes, for use as bi-functional molecular wires. These are shown to be capable of immobilising heme on carbon and gold surfaces via appropriate functional groups. Chapter 3 discusses our efforts towards novel analogues of synthetic antimalarials, dispiro-1,2,4,5-tetraoxanes for use as bi-functional molecular wires. The syntheses of many novel precursors; namely functionalised adamantanone derivatives and their corresponding tetraoxanes are presented. Synthetic routes towards bi-functional tetraoxane molecular wires have been extensively optimised and the incorporation of functional groups that are compatible with carbon/gold surfaces has been attempted. Chapter 4 briefly introduces the design and synthesis of β-turn mimetics and the synthesis of chiral enamine N-oxides. Chapter 5 details the experimental procedures.

title: Pulse pressure testing and analysis of steel plates with openings
Creators: name: Underwood, Nicholas
Publisher: name: University of Liverpool Repository
Year: 2014

description: Steel plates are widely used in a variety of civil engineering applications for load bearing structural components, due to their favourable strength to weight ratio. Many of these plates have openings that are commonly used for reducing weight, access for utilities or for inspection in shipping and offshore installations. However the influence of these openings to the structural component’s robustness and resilience against blast loading is relatively unknown, with limited research conducted in this subject to date. Due to the high costs associated with offshore facilities they are typically very congested. This coupled with the producing, processing, storing and transporting of hydrocarbon materials means that explosions and subsequent fires are major hazards with severe consequences. In the event of an explosion, the blast load will initially impact the secondary structure (large spanning plated sections) and then transfer through to the primary structure, highlighting their critical consideration in safety assessments. Plated structures are also known to cause confinement, which in turn will results in higher overpressures, making the consequences of an event more severe. The aim of this research was to investigate the combined influence that openings have on the overpressure and the structural response of thin ductile plates subjected to extreme dynamic transverse loads. This was achieved by conducting a set of well-defined experiments investigating the response of 1/8 scale (0.5 m square) mild steel plates with openings subjected to pulse pressure loading. Six central (scaled) openings were considered; circular (50, 75 and 100 mm) and extended circular (50 by 75, 75 by 100 and 100 by 125 mm) representative of typical offshore and shipping applications. Each plate design was assessed with two boundary conditions (restrained and non-restrained) and two nominal loading conditions. The boundary conditions adopted in this study allowed the response to be bounded, and enabled them to be practicably modelled in FEA-analyses and in the simplified analytical approaches. A pulse pressure test facility was used to generate nominal pulse pressure loads (25 and 50 psi) applied over a time (100 to 200+ ms load duration) representative of extreme explosion loading conditions offshore. All plates exhibited a mode I type failure (large inelastic deformation) highlighting the large reserve strength in such members. The work has shown that the inclusion of an opening (
