    Phytocapping of Landfills

    No full text
    Phytocapping presents a sustainable alternative to the conventional top barrier cover design. It relies on the capacity of a porous substrate (usually of locally available soil) to store water together with the natural processes of surface evaporation and plant transpiration to remove the stored water as a means of controlling water ingress into the landfill. This chapter is based on the Australian experience in researching and implementing phytocaps as final covers for municipal waste landfills. In 2006, the Australian Alternative Cover Assessment Program (A-ACAP) was established to compare the performance (in terms of drainage, landfill gas, and plant growth) of phytocapping against traditional compacted clay barrier caps. The trials showed that phytocapping has the potential to reduce drainage as effectively as compacted clay barrier caps and in a more predictable manner; to oxidize fugitive methane emissions more effectively than barrier caps; and to enable more variable and sustainable vegetation communities to be established. Guidelines published as an outcome of the A-ACAP have been adopted in Australia as a basis for design and are being referenced in regulatory guidance as they are reviewed and updated. Phytocapping has now been approved and constructed in all mainland States (with the exception of Western Australia, where construction is due to commence shortly). The full-scale experience has shown that phytocapping is an alternative to conventional barrier caps but requires specialized input into design and different techniques for construction and maintenance to ensure its continued performance.No Full Tex

    The relationship between ADAMTS13 genotype and phenotype in congenital thrombotic thrombocytopenic purpura and characterisation of ADAMTS13 mutants

    No full text
    Congenital thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy, usually involving ADAMTS13 gene defects. ADAMTS13 processes the multimeric plasma glycoprotein Von Willebrand factor making it less reactive to platelets. Patients differ in terms of disease severity and evidence suggests a relationship between ADAMTS13 genotype and disease phenotype. Over 140 mutations have been identified in patients but only ~30% of these has been expressed in vitro. The aim of this thesis was to study certain ADAMTS13 mutations identified in a homozygous form in congenital TTP patients to assess in vitro their effect on the secretion and activity of ADAMTS13 and to assess their contribution to disease phenotype. ADAMTS13 mutants (p.R102H, p.I143T and p.Y570C) and wild type (WT) were expressed in HEK293T cells. The p.R102H mutation partially affected the secretion of ADAMTS13 and reduced the catalytic efficiency of the mutant but not to the extent predicted based upon levels measured in patient plasma. Expressing this mutant with three ADAMTS13 polymorphisms (p.Q448E, p.P618A and p.A900V) which were also identified in the patient with this mutation further reduced the secretion and activity of ADAMTS13. When these three polymorphisms were expressed separately in WT ADAMTS13, the p.P618A polymorphism reduced the secretion and subsequently the activity of ADAMTS13 suggesting that this polymorphism in particular was responsible for the reduction observed. These results highlight the importance of ADAMTS13 polymorphisms. The p.I143T and p.Y570C mutations severely affected ADAMTS13 secretion. Immunofluorescence studies showed localisation of these mutants within the ER but less extensive localisation within the cis Golgi compared to WT ADAMTS13. The p.I143T mutant was characterised further and was shown to be degraded by the cell proteasome. Addition of a chemical chaperone (betaine) appeared to rescue the secretion defect caused by the p.I143T mutation. This may have future therapeutic implications for the treatment of some congenital TTP patients

    Role of histone methylation in paternal transmission of epigenetic information

    No full text
    During the development of multi-cellular organisms, one genome gives rise to multiple differentiated cell types. This is achieved by sequence specific transcription factors and different epigenetic mechanisms, which collaborate in reading the genetic information. These epigenetic mechanisms coordinate the establishment and maintenance of transcriptional programs in a lineage specific manner during development. However, very little is known whether such epigenetic information can be also passed to the next generation. Mammalian gametes may differ in their potential to transmit chromatin encoded epigenetic information. The oocyte genome is organized in a nucleosomal configuration with DNA wrapped around histones that carry various post translational modifications. By contrast, the paternal genome undergoes a major reorganization during the last stages of spermatogenesis. Most of histones are replaced by protamines, which after fertilization, are exchanged by maternally provided histones. Nevertheless, approximately 10% of histones are retained in human spermatozoa, raising a possibility for a paternal, epigenetic contribution to the next generation. In this thesis, I aimed to determine the genomic localisation of histones retained in sperm and to analyze their potential to influence transcription after fertilization. We show that histones isolated from mouse and human spermatozoa are carrying multiple post translational modifications, many of which have functions in gene regulation. In our genome wide analysis of human promoters, we demonstrate that two of these marks, Trithorax/Set1 mediated dimethylation of lysine 4 of histone H3 (H3K4me2) and Polycomb mediated trimethylation of lysine 27 of histone H3 (H3K27me3), occupy functionally defined groups of genes. H3K4me2-marked promoters control genes with functions in spermatogenesis and cellular homeostasis, suggesting that this mark reflects germline transcription. By contrast, multiple developmental regulators, which are Polycomb targets in pluripotent somatic cells, are marked by H3K27me3 in human sperm. Similarly to somatic cells, the presence of this mark correlates with gene repression during spermatogenesis and in the early embryo. We propose a model in which H3K27me3, transmitted by sperm, assures repression of developmental regulators at the totipotent stage of the preimplantation development. Finally, we demonstrate that a number of these developmental regulators are also marked by H3K27me3 in mouse spermatozoa, implicating an evolutionary conserved role for histone methylation in the paternal transmission of epigenetic information

    Search for non-resonant Higgs boson pair production in the bbℓνℓν final state with the ATLAS detector in pp collisions at s=13 TeV

    A search for non-resonant Higgs boson pair production, as predicted by the Standard Model, is presented, where one of the Higgs bosons decays via the H→bb channel and the other via one of the H→WW⁎/ZZ⁎/ττ channels. The analysis selection requires events to have at least two b-tagged jets and exactly two leptons (electrons or muons) with opposite electric charge in the final state. Candidate events consistent with Higgs boson pair production are selected using a multi-class neural network discriminant. The analysis uses 139 fb−1 of pp collision data recorded at a centre-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. An observed (expected) upper limit of 1.2 (0.9−0.3 +0.4) pb is set on the non-resonant Higgs boson pair production cross-section at 95% confidence level, which is equivalent to 40 (29−9 +14) times the value predicted in the Standard Model. © 2019 The Author(s

    The Back for Action Program for Increasing Everyday Activity Levels: Its Rationale, Design and Experimental Evaluation with People Over 70 Years of Age

    Population ageing and its impact on government provisions for healthcare has focused attention on the development of appropriate services and policies for older people. Considerable resources are being directed towards health promotion media campaigns which aim to encourage older people to initiate and maintain healthier and more active lifestyles. From a behaviour analytic (or ABA) perspective, improving the health and wellbeing of older people involves arranging supportive environments and applying self-management strategies for long-lasting behaviour change from sedentary to more active lifestyles. This important area of application of ABA principles has so far received surprisingly little attention from behaviour analysts. This thesis describes the rationale, development and evaluation of the Back for Action Program (BAP), a comprehensive intervention based on ABA principles that aims to increase the everyday physical activities of older people. The main components of the BAP are described, including how it selects, measures and reinforces increased physical activity in people over 70 years of age. The first research study undertaken consisted of 7 single-case experiments that were designed to evaluate the effectiveness of the main components of the BAP: client feedback based on objective measures of daily activities, behavioural consultation including goal setting and problem solving, and self-management strategies for maintenance. The second research study consisted of a repeated measures group design evaluation involving arbitrary allocation of participants (n = 19) to either the BAP as a package or a ‘control’ condition. The effects of the BAP were evaluated using a comprehensive set of direct and collateral dependent measures of health and wellbeing. These covered participants’ physical, biochemical and psychological health and wellbeing. Research questions included whether the BAP leads to increases in daily activity and reduces sedentary behaviours, and whether higher levels of activity lead to improvements in measures of physical, biochemical, and psychological health and wellbeing. Results provided strong evidence in support of the BAP and showed that increasing daily activity levels by 20% to 103% had clinically significant health benefits even for this older group of people. In so doing, this thesis provides an overdue account of a comprehensive, effective behavioural approach to increasing ‘healthy ageing’ activities of free-living older people in the community

    Search for displaced vertices of oppositely charged leptons from decays of long-lived particles in pp collisions at s=13 TeV with the ATLAS detector

    A search for long-lived particles decaying into an oppositely charged lepton pair, μμ, ee, or eμ, is presented using 32.8fb−1 of pp collision data collected at s=13 TeV by the ATLAS detector at the LHC. Candidate leptons are required to form a vertex, within the inner tracking volume of ATLAS, displaced from the primary pp interaction region. No lepton pairs with an invariant mass greater than 12 GeV are observed, consistent with the background expectations derived from data. The detection efficiencies for generic resonances with lifetimes (cτ) of 100–1000 mm decaying into a dilepton pair with masses between 0.1–1.0 TeV are presented as a function of pT and decay radius of the resonances to allow the extraction of upper limits on the cross sections for theoretical models. The result is also interpreted in a supersymmetric model in which the lightest neutralino, produced via squark–antisquark production, decays into ℓ+ℓ′−ν (ℓ,ℓ′=e, μ) with a finite lifetime due to the presence of R-parity violating couplings. Cross-section limits are presented for specific squark and neutralino masses. For a 700 GeV squark, neutralinos with masses of 50–500 GeV and mean proper lifetimes corresponding to cτ values between 1 mm to 6 m are excluded. For a 1.6 TeV squark, cτ values between 3 mm to 1 m are excluded for 1.3 TeV neutralinos. © 2019 The Author(s

    An evaluation of the implementation of Total Quality Management (TQM) within the construction sector in the United Kingdom and Jordan

    No full text
    Recognising quality to be a key focus for competitiveness, Total Quality Management (TQM) was established and used in developed countries as a continually evolving philosophy for managing organisations. However, TQM in developing countries has received little attention and little research has been conducted into the successful implementation of TQM system in these countries in comparative with developed countries. The research described in this thesis assesses the adoption of TQM factors in the Construction industry in the UK and Jordan. This comparative study aimed to investigate if TQM implementation is fundamental for the Construction industry and to identify the critical success factors for successful implementation. In addition this research explores the benefits of applying TQM system and the main impediments to successful adoption, also the impact of TQM in improving competitiveness. In order to understand the reasons behind low competitiveness level by the Jordanian companies against international construction companies operating in Jordan, and to investigate the reason behind the sudden drop of the quality scale in the Jordanian Construction industry, both questionnaires and face-to-face individual semi-structured interviews were employed to fulfil the study objectives. The semi-structured interviews aimed to gain deep understanding of TQM implementation by targeting general managers, project managers and project supervision team, while the questionnaires aimed to investigate the implementation of TQM implementation, TQM implementation benefits and impediments, and TQM implementation impact on competitiveness (profitability, market share, quality services) from employees, clients, and final users’ perspectives in the UK and Jordan. Analysis of the data revealed that time and cost, juxtaposed with the non-implementation of TQM and learning practices, can further vex quality failure in the Jordanian Construction companies, which in turn manifest themselves as customer dissatisfaction, rework, bad reputation, and reduce turnover. Construction companies have not pro-actively embraced TQM system because it is mistakenly considered to be an extra cost and perceived as programme of change. While in the United Kingdom the results show that TQM system is being increasingly adopted in the Construction companies to solve quality problems. The implementation of a TQM based on cultural change in addition to changing management behaviour, to move the organisations toward TQM culture that focuses on quality as a key strategy to satisfy customers. The study has made a significant contribution to the knowledge of TQM. This research helps to understand the TQM implementation in the Jordanian Construction companies based on the UK construction companies experience in TQM implementation. Some recommendations for further research have been derived from this research, such as, Contractors need to focus on aspects of performance, time, the establishment of long-term partnerships with subcontractors and maintenance of a well-trained workforce to improve overall performance and quality services, Jordanian construction companies should embrace a degree of transformational change by adopting a customer focus strategy instead of a price focus strategy, Jordanian construction companies need a cultural change which cannot be achieved without changes to norms, beliefs and values, and more attention is needed in the marketing element within the Jordanian construction as it has a direct impact on improving organisational market share

    Teachers' Reactions to Foreign Language Learner Output

    [eng] "Teachers' Reactions to Foreign Language Learner Output" BY: Leticia Vicente-Rasoamalala TEXT: A series of theoretical and practical educational studies have suggested that learners need teacher assistance to progress in their learning. Therefore, a considerable amount of language classroom research has been concerned with the study of teacher activities, especially those focusing on their instructional methods. In an attempt to contribute to this research area, the general objective of the dissertation is to develop a better understanding of one recurrent practice in formal FL instruction: how teachers react to FL learner output in classroom oral interactions. To this end, the formal features and phenomena involved in Teacher Reaction Episodes (TREs) are addressed. 'Teacher reactions' refer to any instructional strategies that handle language learner oral productions. In traditional SLA research, this teacher practice has been conceptually examined under the rubric of 'corrective feedback'. This thesis covers multidisciplinary theoretical and methodological approaches related to TREs. Part I (Chapters 1-4) puts in perspective the general conceptual framework that underpins the empirical second part of the thesis. A literature review encompasses: i) general and specific components comprising TREs), ii) the features surrounding these instructional moves, iii) their potential benefits for FL learner acquisition and, iv) the methodological frameworks previously used to examine teacher reactions. We have identified the key questions that SLA research has addressed in relation to "Teacher Reactions to Foreign Language Learner Output" by covering different methods of enquiry such as: 1) SLA theories 2) Socioculturalism 3) FL classroom social interaction studies 4) Teacher reaction features in the light of SLA works Part II (Chapters 5-8) describes microanalysis case studies carried out for observing and identifying the turns of TREs. Video data collected from two Senegalese international bilingual schools illustrate the differential effects of teacher reactions on FL learner uptake. Through corpus-based evidence from three immersion settings, an attempt is made to discover conditions and means for felicitous TREs in acquisitional terms. The term "immersion" refers to the teaching approach in which students receive academic instruction of core content subjects in a language that is not usually their mother tongue (Wesche, 2001). Specifically, 3 language teachers were observed with their students in their FL immersion classrooms in three main differentiated learning settings, which involve different levels and languages: i. Advanced English immersion (Years 1, 2, 3, 4, 5 and 6) at the primary school (Setting 1); ii. Intermediate English immersion (Years 1, 2, 3, 4, 5 and 6) at the primary school (Setting 2); iii. Spanish as L3 immersion (Years 9 and 10) at the secondary school (Setting 3) In order to conduct further research in the area of teacher feedback (Lyster & Mori, 2006; Lyster & Ranta, 1997), this study has focused on teacher reactions to foreign language learner output in such peculiar formal instruction (FI) learning contexts. A total of 14 lessons were observed to this end in each classroom year level. This part of the dissertation has been theoretically and methodologically framed into one hybrid approach covering diverse complementary perspectives. For instance, the SLA social interactionist views, socioculturalism, Conversation Analysis and ethnomethodology. In methodological terms, this study aimed at: 1) describing the way(-s) in which learners and teachers verbally and non-verbally engage didactic negotiations during TREs; 2) identifying how TREs might be salient for language acquisition in engaging learner noticing of their deviant target language forms; 3) investigating if learners engage after teacher interventions, pay attention to their errors, and if they might fruitfully self-repair; 4) surveying teacher and learner beliefs on TREs. The results seem to reflect certain trends in relation to the error types, the kinds of teacher reactions and the immersion settings, classroom years and levels vis-à-vis learner uptake. Globally, learners receiving metalinguistic feedback appear to generate more uptake than those receiving recasts.[spa] Reacciones docentes ante el output de los aprendices de lenguas extranjeras TEXTO: Una serie de estudios teóricos y prácticos que versan sobre aspectos educativos han postulado que el soporte del profesor es necesario para la progresión del aprendizaje de los estudiantes. Por esta razón, un número considerable de trabajos ha indagado sobre las actividades docentes haciendo especial hincapié en los métodos didácticos aplicados con el fin de examinarlas. En un intento de contribuir en esta área de investigación, el objetivo general de esta tesis es profundizar en una práctica docente recurrente en la enseñanza de idiomas. Se trata de las reacciones de los profesores ante el output de los aprendices que tienen lugar durante las interacciones orales en las aulas de lenguas extranjeras. En particular, se pretende examinar los rasgos formales de los "episodios de reacciones docentes" (ERD) y los fenómenos circundantes que se manifiestan en ellos. Las "reacciones docentes" se refieren a la totalidad de estrategias didácticas verbales y no verbales que se despliegan ante las producciones orales de los aprendices de idiomas. Tradicionalmente, el campo de la adquisición de lenguas segundas examina de manera conceptual esta práctica docente como "feedback correctivo". Este trabajo contextualiza los estudios teóricos y metodológicos multidisciplinarios afines con los ERD abarcando: i) los componentes generales y específicos de los episodios de reacciones docentes, ii) las condiciones que rodean estas acciones, iii) los beneficios potenciales para el aprendiz en relación con el "feedback" o la retroalimentación docente en diferentes contextos de adquisición de lenguas y iv) los marcos metodológicos previamente aplicados para examinar las reacciones del profesor o del instructor de lenguas. Los datos recogidos mediante una videocámara en dos escuelas bilingües internacionales privadas de Senegal ilustran los efectos diferenciados de las reacciones docentes sobre las producciones subsiguientes ("uptake") de los aprendices. A través de un corpus basado en datos empíricos extraídos de tres contextos de inmersión, se ha intentado hallar las condiciones y los recursos que podrían posibilitar que las reacciones docentes ante el output de los aprendices de idiomas sean más facilitadoras en términos de adquisición. En el presente estudio, la provisión de feedback metalingüístico pareció generar más "uptake" por parte de los aprendices que en el caso de las reformulaciones
