The undertakers : learning from an unusual work experience placement
No full textProviding care for dying patients and their families is a fundamental part of general practice. There are barriers to the effective provision of such care at both individual and organisational levels (Mitchell et al., 2016), as well as cultural and social barriers to discussing the end of life and dying (www.dyingmatters.org). The extent to which we are exposed to death during training is highly variable, and the way that we are educated to cope with both the practicalities and the emotional aspects of death and dying receives little attention in undergraduate or postgraduate training
Rayleigh number dependence of the Archimedes number dependent large-scale flow structure formation in mixed convection
No full textWe report on experimental investigations of large-scale flow structure formation in mixed convection. We characterize the flow field by measuring the velocity fields within a rectangular model room using 2D2C PIV. The control parameters are the Reynolds number Re, the Rayleigh number Ra and the Prandtl number Pr. All parameters are linked through the Archimedes number Ar. In 6.4x10-2 ≤ Ar ≤ 1.39x101, 4.2x103 ≤ Re ≤ 6.35x104 and Ra = 3.1x107, Ra = 1.8x108 and Pr = 0.713 we found flow 3 different flow structures. While keeping Ra and Pr constant and varying Ar through Re variations, we found an Ar dependence of the largescale flow structure formation within 6.4x10-2 ≤ Ar ≤ 1.39x101. Furthermore, we found a Ra dependence of the structure formation, which shifts the transition points between the structures to higher Archimedes numbers and reduces the mean velocities within the investigated domain
‘Lost time’. Patients with Early Inflammatory/Rheumatoid Arthritis and their experiences of delays in Primary Care.
No full textBackground
Early referral forms a crucial part in early inflammatory/rheumatoid arthritis (EI/RA) recovery. Delayed decisions to refer can lead to severe incapacity and emotional distress for individuals and family and feelings of lost time. How patients with EI/RA experience early referral decisions in Primary Care is an under explored area and warrants further investigation.
Aim: To explore how patients newly diagnosed with EI/RA experienced their early contacts with Primary Care as they negotiated their journey through the referral process into secondary care.
Design and setting
Qualitative face to face interviews with newly diagnosed EI/RA patients
Methods: In-depth semi-structured interviews were conducted to explore patients’ experiences of referral from first symptoms to GP referral All participants were interviewed within two weeks of being diagnosed in Secondary Care. Data analysis was conducted using Interpretative Phenomenological Analysis (IPA).
Findings: All participants in this study described having experienced struggles with their navigation through Primary Care towards diagnosis and specialist EI/RA services. This struggle comprised 5 key elements: ‘Family persuasion, ‘Lack of continuity in care’, ‘Pushing for referral’, ‘Straining relationships’, ‘Lost time’.
Conclusion: The delays experienced by patients when attempting to reach an early referral decision in Primary Care cause frustration for those presenting with EI/RA, partly because they do not feel heard. There is a significant impact on patients and their families when referral to specialist care is delayed
Reynolds numbers near the ultimate state of turbulent Rayleigh-Bénard convection
No full textWe report on measurements of the mean-flow Reynolds number ReU and the rms fluctuation Reynolds number ReV in turbulent Rayleigh-Bénard convection as a function of the Rayleigh number Ra for 4 x 1011 < Ra < 2 1014 and Pr ' 0:8. Both can be described by the same power law with an effective exponent = 0:44, in agreement with predictions for ReU but in disagreement with predictions for ReV
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
Lagrangian Raylaigh-Bénard convection
No full textUsing passive tracers as sensors, we obtain Lagrangian measurements of tracers position, velocity and temperature in Rayleigh-Bénard convection at Ra=10^7-10^9. We report on statistics of temperature, velocity, and heat transport (Nusselt number). We observe that the Nusselt number is characterized by a largely intermittent behavior, likely due to the interaction of temperature with turbulent velocity fluctuations
SMALL MAMMALS OF THE MITCHELL PLATEAU REGION, KIMBERLEY, WESTERN-AUSTRALIA
No full textThis paper presents the background for a series on the biology of small mammals in the Mitchell Plateau region, an area characterised by a wet-dry tropical climate. From June 1981 to December 1982, 19 species of small terrestrial mammals were captured at Mitchell Plateau. Of 17 species captured on eight mark-release grids, 13 clustered into four significant groups which reflected the major habitats of the region: (1) Sminthopsis virginiae, Leggadina sp. and Pseudomys nanus in riparian and plateau escarpment sites; (2) Phascogale tapoatafa, Trichosurus arnhemensis and Pseudomys laborifex in plateau open forest; (3) Conilurus penicillatus and Mesembriomys macrurus in open woodland and coastal mosaics; (4) the commoner species Dasyurus hallucatus, Isoodon macrourus, Melomys sp. cf. burtoni, Zyzomys argurus and S. woodwardi in an array of habitats. Rattus tunneyi, Pseudantechinus sp., Wyulda squamicaudata and Planigale maculata did not cluster significantly with other species. Two species, Pseudomys delicatulus and Mesembriomys gouldii, were represented by single specimens captured outside the capture-mark-release grids, in sandstone and plateau woodland respectively. Open forests, particularly on the lateritic plateau surfaces, had the richest and most diverse mammal assemblage over the entire study period. The vine thickets and sandstone contained relatively stable populations of fewer species, and several habitats had seasonally variable populations and species
The Effectiveness of the Mitchell Method Relaxation Technique for the Treatment of Fibromyalgia Symptoms: A Three-Arm Randomized Controlled Trial
No full textObjective: To evaluate the effectiveness of the Mitchell Method Relaxation Technique (MMRT) in reducing symptoms of fibromyalgia. Design: A randomised controlled trial was used to compare the effectiveness of self-administered MMRT (n= 67) with attention control (n = 66) and usual care (n = 56) groups. Main Outcome Measures: Primary outcomes included self-reported fatigue, pain, and sleep. Secondary outcomes were daily functioning, quality of life, depression, and coping, anxiety and perceived stress. Outcomes were assessed at baseline, post-intervention (four weeks) and followup (eight weeks). Results: A significant combined improvement on outcomes (p<.005), specific significant effects for sleep problems (d=0.29, p<.05), sleep inadequacy (d=0.20, p<.05), and fatigue (d=0.47, p<.05) were present in the MMRT group. At the follow-up, fatigue did not differ to the post-intervention score (p=.25) indicating short-term sustainability of the effect. The effects on sleep problems and sleep inadequacy were not sustained. The pain levels decreased when the MMRT was practiced three times a week (p<.001). Conclusion: MMRT was effective in reducing pain, sleep problems, and fatigue. High rates of relative risk reduction for fatigue (37%) and pain (42.8%) suggest clinical significance

Aspect-ratio dependence of the transition to the ultimate state of turbulent Rayleigh-Bénard convection
No full textWe report on measurements of the ultimate-state transition in turbulent Rayleigh-B\'enard convection obtained in a large facility known as the ``Uboot of G\"ottingen" and using pressurized sulfur hexafluoride as the convecting fluid. We found that the transition occurs over a range of which becomes more narrow as increases, ranging from which is at most weakly dependent on and close to to which varies from about for to about for
