A Calibration Bound for the M-Theory Fivebrane

We construct a covariant bound on the energy-momentum of the M-fivebrane which is saturated by all supersymmetric configurations. This leads to a generalised notion of a calibrated geometry for M-fivebranes when the worldvolume gauge field is non-zero. The generalisation relevant for Dp-branes is also given.Comment: 9 pages, LaTeX2e, uses vmargin.sty.

On the Energy Momentum Tensor of the M-Theory Fivebrane

We construct the energy momentum tensor for the bosonic fields of the covariant formulation of the M-theory fivebrane within that formalism. We then obtain the energy for various solitonic solutions of the fivebrane equations of motion.Comment: 12 pages, LaTeX2e, uses vmargin.sty and amstex.st

Energy efficient engine: Turbine intermediate case and low-pressure turbine component test hardware detailed design report

A four stage, low pressure turbine component has been designed to power the fan and low pressure compressor system in the Energy Efficient Engine. Designs for a turbine intermediate case and an exit guide vane assembly also have been established. The components incorporate numerous technology features to enhance efficiency, durability, and performance retention. These designs reflect a positive step towards improving engine fuel efficiency on a component level. The aerodynamic and thermal/mechanical designs of the intermediate case and low pressure turbine components are presented and described. An overview of the predicted performance of the various component designs is given

Energy efficient engine high-pressure turbine detailed design report

The energy efficient engine high-pressure turbine is a single stage system based on technology advancements in the areas of aerodynamics, structures and materials to achieve high performance, low operating economics and durability commensurate with commercial service requirements. Low loss performance features combined with a low through-flow velocity approach results in a predicted efficiency of 88.8 for a flight propulsion system. Turbine airfoil durability goals are achieved through the use of advanced high-strength and high-temperature capability single crystal materials and effective cooling management. Overall, this design reflects a considerable extension in turbine technology that is applicable to future, energy efficient gas-turbine engines

The Threebrane Soliton of the M-Fivebrane

We discuss the supersymmetry algebra of the M theory fivebrane and obtain a new threebrane soliton preserving half of the six-dimensional supersymmetry. This solution is dimensionally reduced to various D-p-branes.Comment: 10 pages, phyzz

A New Massive Type IIA Supergravity From Compactification

We consider the most general form for eleven dimensional supersymmetry compatible with on-shell superfields. This allows for the introduction of a conformal Spin(1,10) connection. In eleven dimensional Minkowski space this modification is trivial and can be removed by a field redefinition, however, upon compactification on S^1 it is possible to introduce a non-trivial `Wilson line'. The resulting ten dimensional supergravity has massive 1-form and 3-form potentials and a cosmological constant. This theory does not possess a supersymmetric eightbrane soliton but it does admit a supersymmetric non-static cosmological solution.Comment: 13 pages, phyzzx.

A developmental investigation of the relationship between appraisals and peer self-esteem in children experiencing peer-aggression

Transactional models of stress and coping emphasize the role played by cognitive appraisals in determining psychological adjustment (Lazarus, 1999). This proposition has been supported by research examining young people's adjustment in relation to family conflict and break-up (Grych et al., 1992). Furthermore, this literature suggests that there is a change in the relationship between appraisals and adjustment at around 10 years of age: specificity of appraisal type (e.g. threat, blame) becomes relevant to outcome after 10 years, whereas before 10 there are either no effects of appraisal on adjustment or a diffuse effect of 'negative' appraisals more generally (Jouriles et al., 2000). However, it is currently unclear whether this developmental progression can be generalized from familial- to social-stressors experienced by children and young people. The current study therefore evaluates the model within the context of a commonly experienced social childhood stressor: peer-aggression

Profile of consumers and their partners of a perinatal and infant mental health (PIMH) service in Australia

© 2017 John Wiley & Sons Ltd The perinatal period is a time of great vulnerability for many women, in particular those with a range of psychosocial vulnerabilities and mental health risk factors. This paper outlines the psychosocial and mental health profile of consumers and their partners of a perinatal and infant mental health (PIMH) service in Australia. To establish the consumer profile, we analysed client vulnerabilities and demographical information maintained over a 6-year period for 406 consumers. Consumer information, including mental health problems, psychosocial vulnerabilities and demographical information, was entered into a standalone database by the allocated clinicians upon service allocation and throughout treatment. The women accepted by PIMH presented with an average of nine different vulnerabilities. Frequently endorsed risk factors included depression (72.66%), anxiety (71.43%), comorbid depression and anxiety (58.13%), self-harm (past, 7.88%, present, 16.26%), a history of family mental health issues (39.66%), childhood trauma (57.88%), limited support (68.84%), relationship conflict with partners (38.92%) and financial stress (47.29%). The women's partners also presented with a range of vulnerabilities, in particular childhood trauma (34.11%) and mental health issues (30.81%). This study contributes to our understanding of the profile of vulnerable women in the perinatal period, and in particular contributes to the literature by highlighting that in addition to depression, anxiety, self-harm and trauma are also significant in PIMH service delivery

Mental Health Attitudes and Beliefs in a Community Sample on the Central Coast in Australia: Barriers to Help Seeking

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. There continues to be call for greater community awareness actions and strategies to reduce stigma and enhance mental health literacy nationally and internationally. To identify local barriers to help-seeking and perceptions around stigma, we developed a ‘mental health attitudes and beliefs’ survey which was administered at a range of community events on the Central Coast in New South Wales, Australia. The aim was for the results of this survey to inform the development of strategies that enhance local help-seeking behaviours that are sensitive to the role of age, gender and Indigenous status. People who approached our Mental Health Information stall were invited to complete the survey and 282 individuals completed the survey. The data was analysed descriptively with a focus on comparing subgroups based on age, gender, Indigenous status, and previous service access or experience of mental illness. Cost, stigma and mental health literacy were found to be prominent barriers to help-seeking for the overall cohort; however, the ways in which or extent to which these barriers impact on help seeking varied between subgroups. A discussion of these differences and their implications for practice is the focus of this paper

Identifying the challenges and facilitators of implementing a COPD care bundle.

BACKGROUND: Care bundles have been shown to improve outcomes, reduce hospital readmissions and reduce length of hospital stay; therefore increasing the speed of uptake and delivery of care bundles should be a priority in order to deliver more timely improvements and consistent high-quality care. Previous studies have detailed the difficulties of obtaining full compliance to bundle elements but few have described the underlying reasons for this. In order to improve future implementation this paper investigates the challenges encountered by clinical teams implementing a chronic obstructive pulmonary disease (COPD) care bundle and describes actions taken to overcome these challenges. METHODS: An initial retrospective documentary analysis of data from seven clinical implementation teams was undertaken to review the challenges faced by the clinical teams. Three focus groups with healthcare professionals and managers explored solutions to these challenges developed during the project. RESULTS: Documentary analysis identified 28 challenges which directly impacted implementation of the COPD care bundle within five themes; staffing, infrastructure, process, use of improvement methodology and patient and public involvement. Focus groups revealed that the five most significant challenges for all groups were: staff too busy, staff shortages, lack of staff engagement, added workload of the bundle and patient coding issues. The participants shared facilitating factors used to overcome issues including: shifting perceptions to improve engagement, further education sessions to increase staff participation and gaining buy-in from managers through payment frameworks. CONCLUSIONS: Maximising the impact of a care bundle relies on its successful and timely implementation. Teams implementing the COPD care bundle encountered challenges that were common to all teams and sites. Understanding and learning from the challenges faced by previous endeavours and identifying the facilitators to overcoming these barriers provides an opportunity to mitigate issues that waste time and resources, and ensures that training can be tailored to the anticipated challenges
