The work group formulated five guiding principles: prevention of the exploitation of recipients of services by staff; the right of recipients to be treated as competent autonomous human beings; recognition that certain developmental stages, treatment settings, and pre-existing relationships increase a service recipient's vulnerability to exploitation and call for more stringent regulation of staff actions; acceptance of a spectrum of permissible relationships for staff and recipients outside of the relationship dictated by the staff member's job description; and recognition of the difference between a relationship focused on treatment or service provision and other professional relationships between providers and current or former recipients. The principles were used to develop a model policy on relationships between staff and recipients that addresses both the organizational complexity and the recipient-centered rehabilitation model of a large state-operated mental health system.
General anaesthesia for intra-ocular surgery still presents a topic of controversy. Most ophthalmic surgeons agree to the use of general anasthesia for extra-ocular surgery or for intra-ocular operations on children. The use of general anzsthesia for cataract extractions on adults is increasing.Cridlandl advocated total general anaesthesia and endotracheal intubation, pointing out, that the full co-operation needed from a patient under local analgesia cannot be achieved in a state of sedation, however complete the pre-operative instructions. To this may be added the frequency of senility or deafness as barriers to complete co-operation in the patients commonly subjected to cataract extractions.These considerations equally apply to the use, suggested by Kirby2 and Ives3, of a state of semi-consciousness induced by the lytic cocktail combined with akinesia through relaxants and retrobulbar injections of a local analgesic. This paper will consider the low incidence of post-operative vomiting, cough and restlessness in a series of 350 cases of cataract extractions and will also deal with the occurrence of intra-ocular complications.
The circular cross-sectional Royal Aerospace Establishment (RAE) 2129 S-shaped intake diffusing duct series, shown in Fig. 1, which has an offset of the inlet and exit centerline of 0·3 and 0·45 of the axial length of the duct, was designed at the RAE (Bedford) and tested at British Aerospace Filton, at low forward speeds (freestream Mach no. range from 0 – 0·2 but a range of duct inlet Mach numbers up to choking speeds) in the last two decades to fulfil the objectives of collecting systematic experimental data on engine face pressure recovery, total pressure flow distortion and wall static pressures for computational fluid dynamics validation. Some of the measurements have been presented, as for example, by Willmer, Brown & Goldsmith. The measurements from one version of Model 2129 (the 0·3 length offset S-duct geometry) have been used to compare with calculated results from a number of CFD programs, as for example, by Anderson, Horton and by the AGARD Working Group 13. The series of comparison also highlight the need for measurements other than the engine face total pressure and wall static pressure which have already been made.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
