Curation, Spacecraft Recovery and Preliminary Examination for the Stardust Mission: A Perspective from the Curatorial Facility

We briefly describe some of the challenges to the Stardust mission, curation and sample preliminary analysis, from the perspective of the Curation Office at the Johnson Space Center. Our goal is to inform persons planning future sample returns, so that they may learn from both our successes and challenges (and avoid some of our mistakes). The Curation office played a role in the mission from its inception, most critically assisting in the design and implementation of the spacecraft contamination control plan, and in planning and documenting the recovery of the spacecraft reentry capsule in Utah. A unique class 100 cleanroom was built to maintain the returned comet and interstellar samples in clean comfort, and to permit dissection and allocation of samples for analysis

Do rural universities produce rural dentists? An exploratory study examining Australian dental graduates of 2015

Rural and remote areas experience ongoing challenges with recruiting and retaining dentists, which results in workforce shortages where the need for oral health services is greatest. The dental workforce maldistribution is evident nation-wide, with a proportion of 56.2 dentists per 100 000 in metropolitan areas compared to 22.9 dentists per 100 000 in remote areas. Underlying this maldistribution of dentists is the difficulty facing rural communities when attracting and retaining dental graduates. The aim of this presentation is to share the results of a study that explored the intentions and destinations of dental graduates from six Australian universities who completed their degrees in 2015. Data was collected via an online survey. GIS mapping methods were used to show the practice locations of participants according to the Modified Monash Model (MMM). GIS mapping revealed that more rural university graduates practiced in MMM zones 3-7 while metropolitan graduates remained in cities. While previous studies have provided insights into the motivational factors that persuade and dissuade dentists from practising in rural and remote locations, our study reveals that the university that graduates’ attended also effects their choice of practice location. Regional universities, such as James Cook and Charles Sturt, were more likely to have graduates who transitioned into the outer regional, rural and remote workforce. Factors that influenced and enabled dental graduate’s decisions will be discussed. As dentists play an important role in the multi-disciplinary healthcare teams servicing rural and remote Australia, the outcomes of this study provide insights into why dental graduates ‘go where they go’. This study enriches the understanding of dental graduate movements upon entry to the workforce. Findings contribute to discussion about the current trends of graduate movement and provide insights into how the dental curriculum and location of a university program can successfully increase motivation to work rurally

Gains Across WHO Dimensions of Function After Robot-Based Therapy in Stroke Subjects

Background Studies examining the effects of therapeutic interventions after stroke often focus on changes in loss of body function/structure (impairment). However, improvements in activities limitations and participation restriction are often higher patient priorities, and the relationship that these measures have with loss of body function/structure is unclear. Objective This study measured gains across WHO International Classification of Function (ICF) dimensions and examined their interrelationships. Methods Subjects were recruited 11 to 26 weeks after hemiparetic stroke. Over a 3-week period, subjects received 12 sessions of intensive robot-based therapy targeting the distal arm. Each subject was assessed at baseline and at 1 month after end of therapy. Results At baseline, subjects (n = 40) were 134.7 ± 32.4 (mean ± SD) days poststroke and had moderate-severe arm motor deficits (arm motor Fugl-Meyer score of 35.6 ± 14.4) that were stable. Subjects averaged 2579 thumb movements and 1298 wrist movements per treatment session. After robot therapy, there was significant improvement in measures of body function/structure (Fugl-Meyer score) and activity limitations (Action Research Arm Test, Barthel Index, and Stroke Impact Scale–Hand), but not participation restriction (Stroke Specific Quality of Life Scale). Furthermore, while the degree of improvement in loss of body function/structure was correlated with improvement in activity limitations, neither improvement in loss of body function/structure nor improvement in activity limitations was correlated with change in participation restriction. Conclusions After a 3-week course of robotic therapy, there was improvement in body function/structure and activity limitations but no reduction in participation restriction

Alternative approach to b−>sγb->s \gamma in the uMSSM

The gluino contributions to the $C'_{7,8}$ Wilson coefficients for $b->s \gamma$ are calculated within the unconstrained MSSM. New stringent bounds on the $\delta^{RL}_{23}$ and $\delta^{RR}_{23}$ mass insertion parameters are obtained in the limit in which the SM and SUSY contributions to $C_{7,8}$ approximately cancel. Such a cancellation can plausibly appear within several classes of SUSY breaking models in which the trilinear couplings exhibit a factorized structure proportional to the Yukawa matrices. Assuming this cancellation takes place, we perform an analysis of the $b->s \gamma$ decay. We show that in a supersymmetric world such an alternative is reasonable and it is possible to saturate the $b->s \gamma$ branching ratio and produce a CP asymmetry of up to 20%, from only the gluino contribution to $C'_{7,8}$ coefficients. Using photon polarization a LR asymmetry can be defined that in principle allows for the $C_{7,8}$ and $C'_{7,8}$ contributions to the $b->s \gamma$ decay to be disentangled. In this scenario no constraints on the ``sign of $\mu$'' can be derived.Comment: LaTeX2e, 23 pages, 7 ps figure, needs package epsfi
