A numerical study is made of the effects of both axisymmetric and non-axisymmetric disturbances on the stability of spiral flow between rotating cylinders. If we let Ω 1 and Ω 2 be the angular speeds of the inner and outer cylinders, and R 1 and R 2 be their respective radii, then for fixed values of η = R 1 / R 2 and μ = Ω 2 / Ω 1 , the onset of instability depends on both the Taylor number T and the axial Reynolds number R . Here R is based on the gap width between the cylinders and the average axial velocity of the basic flow, while T is based on the average angular speeds of the cylinders. Using the compound matrix method, we have computed the complete stability boundary in the R , T -plane for axisymmetric disturbances with η = 0.95 and μ = 0. We find that, for sufficiently high Reynolds numbers, there are two distinct axisymmetric modes corresponding to the usual shear and rotational instabilities. We have also obtained the stability boundaries for non-axisymmetric disturbances for R ≼ 6000 for η = 0.95 and 0.77 with μ = 0. These last results are found to be in substantial agreement with the experimental observations of Snyder (1962, 1965), Nagib (1972) and Mavec (1973) in the low and moderate axial Reynolds number régimes.

The purpose of this study is to understand current practice of patient education by occupational therapy practitioners who work with the geriatric population. A 30-item survey was sent to 97 practitioners in the Indianapolis area. Seventyeight (80.4%) returned the survey. Respondents reported that activities of daily living and safety were two topics taught most frequently. Verbal instructions and demonstrations were two main strategies of patient education. Clients' cognitive function was the biggest factor considered when providing written information. Most respondents used written materials developed by their facilities. Over half of the respondents perceived that clients sometimes had difficulty understanding educational content. Time constraints and limited resources of educational materials were two main barriers to patient education. The majority of practitioners reported that they needed education materials that cover the topic of safety. Further research on developing effective and efficient patient education strategies for gerontic occupational therapy practitioners is encouraged. KEYWORDS. patient education as topic, occupational therapy, agedGerontic occupational therapy practitioners specialize in providing services to meet the need of the elder population (Lewis, 2003). To mitigate chronic diseases or agerelated disabilities, gerontic occupational therapy practitioners often teach older adults new skills (e.g., energy conservation strategies and the use of assistive devices) to perform activities of daily living and instrumental activities of daily living. Patient education is a vital component to teaching these skills, and serves the purpose to empower clients to take part in intervention planning to attain and maintain desirable health outcomes. Therefore, patient education supports a clientcentered intervention approach, which is more than simply telling clients what to do. Converging studies have shown positive effects of patient education on learning skills to manage arthritis, multiple sclerosis, and low vision, and to prevent falls in

IntroductionSex-workers do not always engage with traditional healthcare settings and migrant sex-workers are a growing vulnerable group. Our city uses a ‘managed approach’ to sex-working, with focus on identifying exploitation and trafficking. This gives a unique opportunity for outreach.Aim(s)/objectivesProvide accessible sexual healthcare, health promotion and contraception to sex-workers not accessing care. Evaluate this outreach service after one year.MethodsA partnership was established between the Integrated Sexual Health service and a local Third Sector Sex-work Project. Sex-workers were offered STI testing, treatment, HepB vaccination and contraception in an outreach setting (own homes/workplaces, charity premises, streets).Results (at one year):129 sex-workers seen (289 contacts); 70/129 (55%) were migrant (majority Romanian), 113 contacts; 70% previously unknown to sexual health services. Contraception was extended over the first year and provided to 25 sex-workers; Hep B vaccination offered to all. 45 infections identified in 28/70 (40%) migrants (compared with 26 infections in 21/59 (36%) non-migrant sex-workers): 33/45 Chlamydia: 20 extra-genital (5 pharyngeal, 15 rectal); 5/45 Gonorrhoea (all extra-genital); 8/45 Trichomonas Vaginalis. 27/28 successfully treated (1 moved away). 4 women had re-infection on interval rescreening (all Chlamydia). 1 case of chronic HepB, 1 chronic HepC, no cases HIV or syphilisDiscussionThis new outreach service successfully targeted a vulnerable group with a disproportionately high STI burden (40%). Use of a dedicated outreach team achieved trusted relationships with sex-workers. Secondary benefits included a 250% increase in women identifying as sex-workers accessing mainstream clinics.
