Abstract:
ABSTRACT The role of human leukocyte antigen (HLA) class I supertypes in controlling human immunodeficiency virus type 1 (HIV-1) infection in African Americans has not been established. We examined the effects of the HLA-A and HLA-B alleles and supertypes on the outcomes of HIV-1 clade B infection among 338 African American women and adolescents. HLA-B58 and -B62 supertypes (B58s and B62s) were associated with favorable HIV-1 disease control (proportional odds ratio [POR] of 0.33 and 95% confidence interval [95% CI] of 0.21 to 0.52 for the former and POR of 0.26 and 95% CI of 0.09 to 0.73 for the latter); B7s and B44s were associated with unfavorable disease control (POR of 2.39 and 95% CI of 1.54 to 3.73 for the former and POR of 1.63 and 95% CI of 1.08 to 2.47 for the latter). In general, individual alleles within specific B supertypes exerted relatively homogeneous effects. A notable exception was B27s, whose protective influence (POR, 0.58; 95% CI, 0.35 to 0.94) was masked by the opposing effect of its member allele B*1510. The associations of most B supertypes (e.g., B58s and B7s) were largely explained either by well-known effects of constituent B alleles or by effects of previously unimplicated B alleles aggregated into a particular supertype (e.g., B44s and B62s). A higher frequency of HLA-B genotypic supertypes correlated with a higher mean viral load (VL) and lower mean CD4 count (Pearson's r = 0.63 and 0.62, respectively; P = 0.03). Among the genotypic supertypes, B58s and its member allele B*57 contributed disproportionately to the explainable VL variation. The study demonstrated the dominant role of HLA-B supertypes in HIV-1 clade B-infected African Americans and further dissected the contributions of individual class I alleles and their population frequencies to the supertype effects.

Abstract:
The root is the main site of nitrogen (N) acquisition and aluminum (Al) toxicity. The objective of this study is to investigate whether liming and cultivation of an Al-tolerant rice (Oryza sativa L.) cultivar can improve root growth, thereby increasing N acquisition by rice plants in acid paddy soil. Two rice cultivars (‘B690’, Al-sensitive, and ‘Yugeng5’, Al-tolerant) were cultivated with 15N-labeled urea, and with or without lime in an acid paddy soil (pH 4.9) in pots. We examined root and shoot growth, soil pH, soil exchangeable Al, N uptake, 15N distribution in plant-soil system, and fertilizer N recovery efficiency. Results showed that liming improved the root growth of ‘B690’ by decreasing soil exchangeable Al concentrations, in both N-limited and N-fertilized soils. Liming enhanced the N uptake of ‘B690’ only in the absence of N fertilizer. The root weight of ‘Yugeng5’ was greater than that of ‘B690’ without lime, but the two cultivars showed similar N uptake. The fertilizer N recovery efficiency and N loss did not differ significantly between limed and non-limed conditions, or between the two rice cultivars. Thus, liming an Al-sensitive rice cultivar and cultivating an Al-tolerant one improves root growth, but does not enhance fertilizer N recovery efficiency in the present acid paddy soil.

Abstract:
e16551 Background: Chowell et al. showed that HLA (human leukocyte antigen) class I (HLA-I) heterozygosity may avail to survival benefit from immune checkpoint blockade (ICB) in advanced cancer patients. Among their cohorts of melanoma patients, patients with the HLA-B44 supertype had improved survival, while the individuals with HLA-B62 supertype had worse outcome. However, these observations were not supported by another study of NSCLC patients treated with immune checkpoint inhibitors (ICIs). Now whether HLA-I genotype can serve as predictive marker for ICB treatment of other malignancies such as gastrointestinal cancer remains unclear. Methods: Tumor tissue samples before immunotherapy as well as related clinical data were collected from 91 Chinese gastrointestinal cancer patients receiving anti-PD-1/PD-L1 inhibitors and/or anti-CTLA-4 antibodies. Genomic features of tumor specimens were characterized by whole exome sequencing (WES) and HLA-I genotyping of normal DNA from peripheral blood cells were performed using WES data. Tumor immune microenvironment signatures were examined by RNA-sequencing targeting 395 immune related genes. Results: We observed that the individuals with HLA-B62 supertype (n = 15) had a significantly shorter PFS (median PFS, 1.83 months versus 3.53 months; HR, 2.3; 95% CI, 1.03-5.0; p= 0.009) than that of those without HLA-B62 supertype (n = 35) in a subgroup of patients with microsatellite stability (MSS, n = 50) and it was not so in other patients with microsatellite instability-high (MSI-H, n = 17) or unknown MSI status (n = 24). Moreover, the patients with B62 supertype and TP53 mutations (n = 15) exhibited more markedly shortened PFS (mPFS, 1.8 months versus 5.57 months; HR, 3.9; 95% CI, 1.5-9.6; p< 0.0001) and OS (mOS, 4.2 months versus 17.3 months; HR, 4.5; 95% CI, 1.5-13.2; p< 0.0001) compared to those patients with non-B62 supertype and TP53 wildtype (n = 26). Furthermore, gene expression levels of certain immune activation related pathways or markers (IFN-γ signature, cytolytic marker, etc.) in the patients with B62 supertype and without B44 supertype (n = 23) were statistically lower ( p< 0.05) than in those patients without B62 supertype (n = 62). Chi-square test revealed no correlation between HLA-B62 supertype and TP53 mutation, MSI status, tumor mutation burden (TMB) or PD-L1 expression. Conclusions: HLA-B62 supertype in combination with TP53 mutations may define a subset of gastrointestinal cancer patients who probably fail to benefit from ICIs, especially in MSS patients.

Abstract:
Abstract Rejection of a graft after human leukocyte antigen (HLA)-identical stem cell transplantation (SCT) can be caused by recipient's immunocompetent T lymphocytes recognizing minor histocompatibility antigens on donor stem cells. During rejection of a male stem cell graft by a female recipient, 2 male (H-Y)–specific cytotoxic T lymphocyte (CTL) clones were isolated from peripheral blood. One CTL clone recognized an HLA-A2–restricted H-Y antigen, encoded by the SMCY gene. Another CTL clone recognized an HLA-B60–restricted H-Y antigen. In this study UTY was identified as the gene coding for the HLA-B60–restricted H-Y antigen. The UTY-derived H-Y antigen was characterized as a 10-amino acid residue peptide, RESEEESVSL. Although the epitope differed by 3 amino acids from its X-homologue, UTX, only 2 polymorphisms were essential for recognition by the CTL clone HLA-B60 HY. These results illustrate that CTLs against several H-Y antigens derived from different proteins can contribute simultaneously to graft rejection after HLA-identical, sex-mismatched SCT. Moreover, RESEEESVSL-specific T cells could be isolated from a female HLA-B60+ patient with myelodysplastic syndrome who has been treated with multiple blood transfusions, but not from control healthy HLA-B60+ female donors. This may indicate that RESEEESVSL-reactive T cells are more common in sensitized patients.

Abstract:
ABSTRACT Human immunodeficiency virus type 1 (HIV-1)-specific cytotoxic T-lymphocyte (CTL) responses play a major role in the antiviral immune response, but the relative contribution of CTL responses restricted by different HLA class I molecules is less well defined. HLA-B60 or the related allele B61 is expressed in 10 to 20% of Caucasoid populations and is even more highly prevalent in Asian populations, but yet no CTL epitopes restricted by these alleles have been defined. Here we report the definition of five novel HLA-B60-restricted HIV-1-specific CTL epitopes, using peripheral blood mononuclear cells in enzyme-linked immunospot (Elispot) assays and using CTL clones and lines in cytolytic assays. The dominant HLA-B60-restricted epitope, Nef peptide KEKGGLEGL, was targeted by all eight subjects with B60 and also by both subjects with B61 studied. This study additionally establishes the utility of the Elispot assay as a more rapid and efficient method of defining novel CTL epitopes. This approach will help to define new CTL epitopes that may play an important role in the immune control of HIV-1.

Abstract:
1. B31 and B32 are pattern-initiator neurons in the buccal ganglia of Aplysia. Along with the B61/B62 neurons, B31/B32 are also motor neurons that innervate the 12 buccal muscle via the I2 nerve. This research was aimed at determining the physiological functions of the B31/B32 and B61/B62 neurons, and of the I2 muscle. 2. Stimulating the I2 muscle in the radula rest position produces radula protraction. In addition, in behaving animals lesioning either the muscle or the I2 nerve greatly reduces radula protraction. 3. During buccal motor programs in reduced preparations, B31/B32 and B61/62 fire preceding activity in neuron B4, whose firing indicates the onset of radula retraction. In addition, during both ingestion-like and rejection-like patterns the activity in the I2 nerve is correlated with protraction. 4. B31/B32 fire at frequencies of 15-25 Hz. Neither B31/B32 nor B61/B62 elicit facilitating end-junction potentials (EJPs) and electromyograms (EMGs) in the I2 muscle. EMGs from B31/B32 are smaller than those from B61/B62. B31/B32 and B61/B62 innervate all areas of the muscle approximately uniformly. 5. In behaving animals, EMGs consistent with B31/B32 activity are seen in the I2 muscle during the protraction phase of biting, swallowing, and rejection movements. In addition, the I2 muscle receives inputs that cannot be attributed to either the B31/B32 or B61/B62 neurons, either because the potentials are too large, firing frequencies are too low, or a prominent facilitation is seen. Such potentials are associated with lip movements, and also with radula retraction. 6. EMGs were recorded from the I2 muscle during feeding behavior after a lesion of the I2 nerve. Animals that had severe deficits in protraction showed no activity consistent with B31/B32 or B61/B62, but did show activity during retraction. 7. Our data indicate that the I2 muscle and the B31/B32 motor neurons are essential constituents contributing to protraction movements. Activity in these neurons is associated with radula protraction, which occurs as a component of a number of different feeding movements. The I2 muscle may also contribute to retraction, via activation by other motor neurons.

Abstract:
There are several activities in the educational development of young children which require them to speak aloud to a parent or teacher. High pupil-teacher ratios and modem lifestyles limit the time available for one-to-one interaction so the benefits of enabling a computer to assist in this area are significant. There are several large international research projects attempting to implement customised systems with the aim of becoming automated reading tutors within the next few years. This thesis considers a different approach; it tests the feasibility of using commercial speech recognition technology with young children. Commercial technology has the advantage of being available now and it has matured enough for standards to have been developed which enable a speech application to easily use alternative recognition technologies if required. Recognition accuracy needs to be measurable; to simplify and disambiguate the measurement of recognition accuracy, a new metric has been developed. Improvements in recognition accuracy have been found through experimentation. The experiments need a large amount of speech data from children. To facilitate this, a set of tools has been developed to collect a speech corpus from three different regions of the country then automatically measure the recognition effectiveness under different test conditions. Speech recognition is one of several input modes which support a multimodal interface; for it to be effective, the interface with which it is integrated also needs to be effective, so this thesis additionally studies the area of Child-Computer Interaction; one of the outcomes of this study is a set of interface design guidelines which have been developed through the implementation and evaluation of several multimedia applications. Several user evaluation methods have been used to test the applications with young children in the classroom and their effectiveness is discussed. The thesis integrates the speech recognition and Child-Computer Interaction studies to produce a speech-enabled application using the developed interface design guidelines and proposed speech interface design guidelines. The application was evaluated in the classroom with very encouraging results. The thesis concludes that commercial speech recognition can be used effectively with young children if the limitations, optimisations and guidelines developed during this project are considered.

Detta examensarbete har genomförts hos Weda AB gällande deras bottensug B600. Syftet med projektet har varit att åstadkomma en ökning av robotens automationsgrad för att eliminera behovet av övervakning och samtidigt minska robotens operationstid per rengöringscykel. För att öka automationsgraden har en kursavvikelse, som uppkommer i samband med robotens övergång från poolens djupa del till dess grunda del, undersökts. Fokus har legat på att minska denna avvikelse genom att ta fram ett mekaniskt tillbehör som enkelt kan monteras på roboten. Två stycken iterationer av prototypen har tillverkats och testats. Den andra iterationen kunde inte validera lösningen på grund av oförutsedda problem. En tredje iteration har som resultat av detta teoretiskt föreslagits med syfte att lösa dessa problem för att kunna validera konceptets verkan. Fortsatt testning av den tredje iterationen kommer därmed att vara avgörande för ifall konceptet som helhet fungerar som tänkt.<br>This thesis has been carried out at Weda AB regarding their bottom suction robot B600. The purpose of the project has been to achieve an increase in the robot's degree of automation to eliminate the need for monitoring and at the same time reduce the robot's operating time per cleaning cycle. To increase the degree of automation, a deviation of the course that occurs in connection with the robot's transition from the deep part of the pool to its shallow part has been investigated. The focus has been on reducing this deviation by developing a mechanical accessory that can be easily mounted on the robot. Two iterations of the prototype have been manufactured and tested. The second iteration could not validate the solution due to unforeseen problems. As a result, a third iteration has been theoretically proposed with the aim of solving these problems. Continued testing of the third iteration will thus be decisive for whether the concept as a whole will work as intended.

Abstract:
The transition in the energy market, from large fossil fuel consumption to the broad diffusion of renewable energies, involves an intermediate phase where more efficient techniques are developed for the existing power generation technologies. Among new combustion techniques, MILD (Moderate or Intense Low-oxygen Dilution) combustion is particularly attractive because of its potential characteristic to enhance thermal efficiency and reduce emissions like nitrogen oxides (NOx). The successful application of MILD combustion requires a significant entrainment of hot combustion products into the fuel and/or oxidizer stream(s), yielding an increase of the reacting mixture temperature over its auto-ignition value. Such intense dilution causes a reduction in peak temperature levels, with a consequent reduction of NOx emissions, and a homogeneous temperature field followed by enhanced flame stability. Also the overall thermal efficiency is improved because of the recuperated heat. The relative ease of obtaining reactant dilution in a full scale burner makes the MILD combustion regime interesting also from a technological point of view. Despite some interesting applications of MILD technique in industrial cases, its broad adoption is prevented by gaps in the knowledge of this combustion regime. Particularly, the development of simple and reliable numerical models is required to allow testing of full scale industrial burners with reasonable computational expense. The present dissertation is focused on how the oxidiser temperature, oxidiser concentration and fuel concentration affect the complex interaction among molecular transport, chemical kinetics and turbulence that leads to self-ignition in MILD combustion. The diffusion-chemistry contribution to ignition is investigated by means of a one dimensional (1D) zero velocity Direct Numerical Simulations (DNS) of two mixing layers representing a cold fuel mixture and a hot diluted oxidiser. Different oxidiser mixtures as well as different fuel blends are considered. Each case studied showed a different ignition behaviour. An in deep investigation of physical and chemical changes observed for each case along the ignition period is provided. A temporal and a spatial scaling methods are proposed to account for ignition behaviour differences and compare cases. The comparison revealed different aspects of the self-ignition process. The differential diffusion effect plays an important role in the early stages of ignition, for cases presenting methane/hydrogen fuel mixture. If high is the level of hydrogen in the fuel blend, major stages of methane (CH<sub>4</sub>) consumption pathway,from the CH<sub>4</sub> dehydrogenation to the carbon dioxide (CO<sub>2</sub>) release, are significantly affected by hydrogen (H<sub>2</sub>) chemistry. In the latest stages of ignition, the methane pathway is also affected by the drop in oxygen level. The influence of turbulence on the diffusion-chemistry interaction is studied by means of three-dimensional (3D) Direct Numerical Simulations modelling a methane/hydrogen circular jet mixing with a diluted oxidiser co-flow. The effects of different fuel and oxidiser blends is also considered in the 3D study. In cases where large is the H2 presence in the fuel jet, the presence of turbulent mixing has a minimal effects on early stages of self-ignition, where instead differential diffusion still plays a major role. As turbulence develops, more marked difference between 1D and 3D studies are observed. The role of turbulent mixing dominates over chemistry where the fuel blend includes a low amount hydrogen. For this configuration the temperature increment is strongly limited compared to corresponding 1D study. The outcome of this study is expected to be of use to other researches in MILD combustion, particularly those adopting existing RANS and LES models to MILD combustion cases.

Abstract:
There is a wealth of literature on the definition of corruption, its effects and preventative measures. Academics, non-government organisations, law and policy makers have grappled with what constitutes a phenomenon, which, despite being secretive, can still have a huge impact on societies, or that is such a common practice that to progress in life there is no alternative but to take part. However, there has never been a study that has utilised the opinions of the Anti-Bribery & Corruption function within the financial services sector and collectively analysed these against two other forms of data collection. The project has gathered opinions across three Strands. These included the interviewing of 10 Anti-Bribery & Corruption specialists in the UK, the issuance of an anonymous survey which received 173 responses and three focus groups held with financial services professionals in Hong Kong with eight attendees, India with eight attendees and Mexico with 10 attendees. This thesis presents a collective view on the challenges of defining corruption and the differences in legislation, along with an analysis as to which preventative measures are the most effective at reducing corruption. It is clear that even from a small-scale study corruption does not distinguish between western or non-western countries, although the visibility of it in everyday life may differ. Findings are given and recommendations are made to produce a global definition, supported by guidance notes; to increase academic research on corruption within developing countries; and to raise awareness of the limitations of Transparency International's Corruption Perceptions Index and the consequences if misused. Additional recommendations are made that, if combined, may help to reduce the impact of corruption.

Abstract:
Patient-Reported Outcome Measures (PROMs) are increasingly used in health services research and clinical practice for the quantification of patient experiences, including quality of life, mood (e.g. depression), and satisfaction with services. Such PROMs usually take the form of questionnaires. The underlying measurement model is derived from psychometric theory, specifically Classical Test Theory (CTT). This model requires statistical analysis of questionnaire data to establish the quality of data so collected, with emphasis on the reliability (reproducibility) and validity (domain-specific measurement) of the data.

I studied loggerhead shrikes (Lanius ludovicianus) in the Shenandoah Valley in Virginia from April 1987 to April 1988; factors affecting mortality rates wring the breeding season, fall dispersal, and winter were investigated., The high reproductive,success in this study was similar to that reported by other researchers in the United States. Reproductive success was different among varying grass heights and varying amounts of bare soil areas within 100 m of shrike nests; success was highest in habitats with numerous bare soil areas and medium grass. I radio-harnessed fledglings at a mean age of 56 days to document dispersal, fall home-range areas, and survival rates. During the postfledging dispersal period, survival rates were 100% fledglings dispersed at a minimum of 78 days of age, and fall home-ranges typically contained medium grass and numerous bare soil areas. These habitat characteristics may provide shrikes with increased invertebrate availability. Winter negatively affected the loggerhead shrike population in Virginia; raptor predation was the primary cause of subadult and adult mortality, and road kill was secondary. Shrikes moved from grassland areas to shrub-forest areas during inclement weather and preyed on small birds. Home-range sizes were larger during the winter than at other times of the year. I documented the occurrence of low levels of organochlorine and organophosphates in all birds analyzed for pesticide contamination. Also, I present statistical models to predict age and sex of loggerhead shrikes; wing chord and tail white on rectrix 5 were the most useful variables in discriminating sexes and wing chord was used in discriminating ages. More research is needed on the effects of raptors on shrike populations and on the role of foraging habitat on winter areas.<br>Master of Science

Abstract:
The re-conceptualisation of stroke unit provision towards acute and hyperacute care has been a relatively recent development in the United Kingdom. This hermeneutic phenomenological study aimed to explore how the acute stroke unit (ASU) experience, as the phenomenon of interest, was meaningfully lived from a human lifeworld perspective. Eight participants: four stroke survivors and four healthcare practitioners: took part in semi-structured interviews, and if they agreed, an optional creative element. Interviews were recorded then transcribed. Detailed hermeneutic analysis drawing on interpretative phenomenological analysis (IPA) was undertaken firstly on each person’s account, and then across the collective from each perspective. An additional close textual reading was developed for one stroke survivor and one healthcare practitioner. A particular feature of the analysis was its influence in generating an innovative graphic interpretation of the research findings. The stroke survivors experienced the ASU as a lived space in two differentiated forms. The ASU holding space, through the spatial practices of nurses, and others, including similar others (patients), was understood to provide them with protection and safe haven; holding them intimately but also at a distance, so that they could think, make sense, plan and work towards transition. The transitional space of the ASU was experienced by three of them in more disparate ways, and represented how they transitioned their self (for protection, necessity and for recovery) in response to the stroke, the hospital space and the spatial practices of the ASU. The healthcare practitioners experienced the ASU as a space that they produced and appropriated for themselves and others. This was intertwined with their work as existential project; through their relationships with others, and their contribution to patients’ transitional work, they were understood to experience authenticity and belonging. This project was always in the making, and was undertaken amidst the day-to-day pressures on the unit. As a result, three of the health practitioners looked to make sense, navigate, and survive the vulnerability they experienced in relation to their meaningful work, as part of their ASU experience. Further synthesis of these two horizonal1 perspectives elucidated 3 key areas of new insight and understanding: the spatiality of the lived experience of the acute stroke unit, suffering and thriving as a human being, and the intertwining of multiple selves in time and place. The implications of this new knowledge for clinical practice, education, and research are further discussed in this thesis.

Abstract:
This thesis examines how women with a diagnosis of borderline personality disorder (BPD) negotiate their identity in relation to risk, also referred to as their ‘risk identity’. This is defined as, ‘…the view people have of themselves and project to others in their talk and actions in relation to risk and risk taking’. The theoretical perspective which underpins the study is informed by ontological realism, epistemological discursive/linguistic social constructionism, and an ideological critical liberatory position primarily derived from the work of Foucault (1978; 1991a; 1991b; 1998; 2002; 2008a; 2008b; 2009). This perspective informed the decision to adopt email interviews as a method for generating appropriate texts for analysis. Eight women diagnosed with BPD were interviewed over a period of ten months. Adopting a critical emancipatory methodology which incorporated feminist principles of research, Lather’s (1991) adaptation of Van Maanen’s (1988 cited in Lather 1991) ‘four tales’ was employed to view and analyse the texts from four theoretical perspectives; a ‘Realist Tale’, a ‘Critical Tale’, a ‘Deconstructivist Tale’, and a ‘Reflexive Tale’. By ‘layering’ these tales, the findings revealed sets of tensions discernable within the context of interactions with staff, the nature of services, and the wider material and discursive resources at play which inform how risk identities are negotiated. Converging Western discourses of the subject, binary gender discourse, neoliberal discourse, ‘psy’ discourses, and discourses around motherhood were found to be key discursive resources through which risk identity is produced, resisted and projected. In addition these to broad discursive findings, the study also contributes to the existing empirical literature that focuses on the lived experience of those with a BPD diagnosis. A conclusion is drawn that women with a BPD diagnosis not only receive a label which discursively excludes them from being able to be viewed as a ‘good subject of psychiatry’ (and hence leads to them being viewed as dangerous and risky), but that their difficulties and need for relational approaches to manage risk and promote recovery run counter to the way that mental health services are structured in the current neoliberal era.

Abstract:
Introduction The centrality of the patient to health care has been increasingly recognised both politically and professionally. Patient-centred care has become synonymous with high-quality care and a number of studies have reinforced patient's desire for, and the positive impact of the approach. Although the concept emerged over 30 years ago, it is still not clear what it is, upon what theories it is based, or how to measure it. Whilst the concept has been explored within medicine, nursing and other allied health professions, within physiotherapy there has only been minimal discussion. The aim of this research was to explore the meaning of patient-centred care in relation to low back pain, from the perspective of musculoskeletal physiotherapists. Methods Purposive sampling was initially used to select participants. Subsequently theoretical sampling was adopted whereby analysis of the data informed the sample selection. Nine musculoskeletal physiotherapists agreed to participate in the study. They ranged in experience from five to 25 years. Individual semi- structured interviews were adopted as the method of data collection. The interviews were audio taped and then transcribed verbatim. Analysis broadly followed the Grounded Theory approach outlined by Strauss and Corbin (1990). It consisted of a process of open, axial and selective coding. Constant comparative analysis resulted in the identification with a core category and three inter-related sub-categories and the development of a substantive theory of patient-centred care.

Abstract:
The present study aims to analyse some special errors in mathematical reasoning concerning a property of the relation “equivalence by dissection” in synthetic geometry (pure geometry). Although this property is of great importance it is regarded as obviousness and its problematic nature is usually concealed in mathematics teaching. This is deeply rooted in the heritage of greek mathematics and proves to be an obstacle to mathematical education. This subject belongs to a particularity of the mathematical background of teaching mathematics; nevertheless, this study includes some ideas both on other (similar) particularities and from different points of view. Classification: A30, B50, B60, CD30, D20, D30, E40. Keywords: Synthetic geometry, measure geometry, equivalence by dissection, mathematical background of mathematical instruction.
