[en] Aim: This paper reports on one part of a larger study. The aim was to explore what the core domain of research means to consultant radiographers in clinical practice and to identify the key factors that facilitate or hinder research activity by this staff group. Design and method: Grounded theory research methodology was employed. This first part of the study involved electronic questionnaires being sent to all those known in consultant radiographer posts in the United Kingdom. Results: Results indicate there are variations across clinical specialties as to the amount and level of research undertaken by consultant radiographers, and not all agreed that research should be a core domain of consultant practice. Main facilitators to research were noted as: time; skills and knowledge of the researcher; a well defined research question. Main barriers to research were noted as: lack of allocated time; lack of skills/experience; clinical workload. Conclusion: Research is one of the four core domains of consultant allied health professional and nursing roles but, as yet, it is not fully embedded into those of all consultant radiographers. Many consultant radiographers appear to spend more of their time on the ‘clinical expert’ element of their role at the expense of the research domain. This study concludes that there is an urgent need for consultant radiographers to understand that research is one of the four core domains and to recognise the need to embed research into their clinical practice. - Highlights: • Consultant radiographers undertake research but have concerns about their research skills. • Research aims to improve practice and patients' experiences. • Relatively few consultant radiographers publish their work routinely. • Consultant radiographers allocate little protected time for research due to clinical demands. • Almost half of the consultant radiographers feel research should not be a core part of their roles.

[en] Aim: This paper reports on one part of a larger study. The aim of the overall study was to explore what the core domain of research means to consultant radiographers in clinical practice and to identify the key factors that facilitate or hinder research activity by this staff group. Design and method: Grounded theory research methodology was employed. This second part of the study involved telephone interviews with twenty five consultant radiographers. Results: Results indicate there are variations across clinical specialties as to the amount and level of research undertaken by consultant radiographers. The principal barriers revealed were: lack of time; excessive clinical workload; lack of skills and confidence to undertake research; poor research culture; and lack of support. The main facilitators noted were: dedicated time, research training and up-skilling; mutually beneficial collaborations; managerial understanding of the research domain of the role; and research focussed on clinical demand. Conclusion: Fulfilling the clinical role is imperative and integral to the profession at consultant level; however, if it is undertaken to the detriment of the other domains then these practitioners may not be operating at ‘consultant’ level. Overall improvements must be made to ensure that the consultant radiographer role is delivering on current expectations and is safeguarded for the future of the next generation of radiographers. - Highlights: • Consultant radiographers undertake research but have concerns about their research skills. • Research aims to improve practice and patients' experiences. • Relatively few consultant radiographers publish their work regularly. • Consultant radiographers allocate little protected time for research due to clinical demands.

[en] The Advanced Light Source (ALS) accelerator is now completed. The numerous conventional magnets required for the booster ring, the storage ring and the low and high energy transfer lines were installed during the last two years. This paper summarizes the various costs associated with the quantity fabrication of selected magnet families. These costs include the costs of prototypes, tooling, coil and core fabrication, assembly and magnetic measurements. Brief descriptions of the magnets and specialized requirements for magnetic measurements are included in order to associate the costs with the relative complexities of the various magnet systems

[en] Determination of the amount of cubic and tetragonal phase in yttria--zirconia using high-angle XRD (x-ray diffraction) has been complicated by problems of resolution and interpretation. The evidence, from electron diffraction studies, for a c→t shear transformation also needs to be taken into account. Two compositions, a 3 and a 5.7 mol % Y₂O₃--ZrO₂, were sintered and thermally treated at different temperatures between 1450⁰ and 1700 ⁰C. X-ray diffraction traces revealed the anticipated tetragonal (400) and (004) reflections. The region of the diffraction pattern that was thought to arise from the cubic phase could be best interpreted as a second tetragonal phase t'. The original amount of cubic phase computed from the t' reflections showed good agreement with the phase diagram of Scott. The lattice parameters of the t' phase were determined, and the volume of the tetragonal (t') unit cell was calculated

[en] This paper reports the isolation of phenoloxidase-negative mutants of the white-rot fungus Phanerochaete chrysosporium and the results of a survey of idiophasic functions among these mutants. The mutant strains were isolated from a medium containing o-anisidine after gamma irradiation of wild-type spores and fell into four classes, divided by the manner in which they mineralized ¹⁴C-lignin wheat lignocellulose. Examples are strain LMT7, which degraded lignin at a rate similar to that of the wild type; strain LMT26, in which degradation was enhanced; strain LMT16, whose degradation rate was apparently unaffected, although the onset of lignin attack was delayed compared with that in the wild type; and strain LMT24, which was unable to evolve significant amounts of ¹⁴CO₂ from the radiolabeled substrate. The mutants were not necessarily defective in other functions associated with idiophasic activities (intracellular cyclic AMP levels, sporulation, extracellular glucan production, veratryl alcohol synthesis). The authors conclude that phenoloxidase activity as detected by the o-anisidine plate test is not necessary for lignin degradation. In addition, mutations resulting in the loss of lignin-degrading ability were not necessarily pleiotropic with other idiophasic functions

[en] Uptake of Tc-99m di-isopropyliminodiacetic acid (DISIDA) by hepatocellular carcinoma was assessed in 30 patients showing obvious liver defects on a Tc-99m tin colloid image. In none of these patients was there complete ''filling in'' of the defects, and even partial ''filling in'' occurred in only 11 (36.7%). There was no uptake of Tc-99m DISIDA by the primary tumor in the remaining 19 patients (63.3%). In 19 of the 30 patients an attempt was made to correlate the degree of histologic differentiation of the tumor with the uptake of DISIDA by the tumor. No difference in uptake could be demonstrated between well, moderately, and poorly differentiated tumors. Tc-99m DISIDA was not taken up by pulmonary metastases in the only two patients tested. The authors conclude that imaging with Tc-99m DISIDA in conjunction with Tc-99m colloid is of no value in the specific diagnosis of hepatocellular carcinoma

[en] Scottish Nuclear owns and operates four advanced gas cooled reactors, two at Hunterston and two at Torness, having a design output capacity of 2640 MW(e), and generates around half of Scotland's electricity. It was formed in 1990 following the split-up of the South of Scotland Electricity Board (SSEB) prior to privatization. It has a staff of around 1700, with approximately 400 located at its East Kilbride design office. This article reviews the inherited documentation structure, its problems and how these have been tackled to provide a user-friendly controlled documentation management system at Torness Power Station.
