    Notes: We demonstrate that electrochemically etched, hydrogen capped SinHx clusters with n larger than 20 are obtained within a family of discrete sizes. These sizes are 1.0 (Si29), 1.67 (Si123), 2.15, 2.9, and 3.7 nm in diameter. We characterize the particles via direct electron imaging, excitation and emission optical spectroscopy, and colloidal crystallization. The band gaps and emission bands are measured. The smallest four are ultrabright blue, green, yellow and red luminescent particles. The availability of discrete sizes and distinct emission in the red, green and blue (RGB) range is useful for biomedical tagging, RGB displays, and flash memories. © 2002 American Institute of Physics.

    Notes: We report laser oscillation at ∼610 nm in aggregates of ultrasmall elemental Si nanoparticles. The particles are ultrabright red emitting, dispersed from bulk Si by electrochemistry. The aggregates are excited by radiation at 550–570 nm from a mercury lamp. Intense directed Gaussian beams, with a threshold, manifest the emission. We observe line narrowing, and speckle patterns, indicating spatial coherence. This microlasing constitutes an important step towards the realization of a laser on a chip, hence optoelectronics integration and optical interconnects. © 2002 American Institute of Physics.

    Notes: This study aimed to explore the use of electronic monitoring within the context of anaesthetic practice. We conducted workplace observation of, and interviews with, anaesthetists and other anaesthetic staff in two UK hospitals. Transcripts were analysed inductively for recurrent themes. Whilst formal sources of knowledge in anaesthesia deal with the issue of monitoring in terms of theoretical principles and performance specifications of devices, anaesthetists in practice often ‘disbelieve’ monitoring information. They call on and integrate other sources of knowledge about the patient, especially from their clinical assessment. The ability to distinguish ‘normal’ and ‘abnormal’ findings is vital. Confidence in electronic information varies with experience, as does the degree to which electronic information may be considered ‘redundant’. We conclude that electronic monitoring brings new dimensions of understanding but also the potential for new ways of misunderstanding. The tacit knowledge underlying the safe use of monitoring deserves greater acknowledgement in training and practice.

    Notes: It is widely believed that the initial degradation of proteins contained in grazed forage is mediated by rumen micro-organisms, but the authors’ recent work suggests that the plant cells themselves contribute to their own demise. In the present study the responses of Lolium perenne leaves to the rumen environment were investigated by using an in vitro system which simulates the main stresses of the rumen but from which rumen micro-organisms were excluded. Degradation of leaf protein and the accumulation of amino acids in tissue and bathing medium occurred over a time-scale that is relevant to rumen function, and in a near 1 : 1 ratio. Significant loss of nuclear material was observed after 6 h incubation and chloroplasts became morphologically more spherical as the incubation progressed. In situ localization suggested that ribulose 1,5 bisphosphate carboxylase/oxygenase was broken down within chloroplasts which from cytology were judged to be intact. We conclude from these data that plant metabolism may play a significant role in breaking down plant proteins within relatively intact organelles in the rumen. The determinations of chlorophyll content and cell viability revealed that the plant processes occurring in the simulated rumen were similar but not identical to those of natural senescence.

    Notes: Aim  To evaluate the effectiveness of a brief motivational intervention on alcohol consumption and misuse in young males with alcohol-related face injury.Design  Randomized controlled trial.Setting  Oral and maxillofacial surgery out-patient clinic in an urban teaching hospital.Participants  One hundred and fifty-one participants were randomized to motivational intervention and control conditions.Interventions  Control was treatment as usual. The intervention was treatment as usual plus a one-session brief motivational intervention administered by a nurse.Measurements  Three sets of measurements were taken at baseline, 3-month and 1-year follow-up. Collateral measurements were also taken at 1-year follow-up. Primary outcome measures were total alcohol consumption, typical weeks consumption and days abstinent in preceding 3 months. Other outcome measures included the Alcohol Use Disorders Identification Test, a short form of the Alcohol Problems Questionnaire, and a measure of satisfaction with social relationships.Results  There was a significant decrease in 84-day total alcohol consumption across the year (P 〈 0.006) and further, a significant effect for the motivational intervention was demonstrated (P 〈 0.029). This pattern was repeated for days abstinent and alcohol consumption in a typical week as well as alcohol-related problems. There was a significantly greater reduction in the percentage of hazardous drinkers in the motivational intervention group (from 60% to 27%, P 〈 0.009) compared to the control group (from 54% to 51%, NS).Conclusion  A proportion of young men change their alcohol consumption following alcohol-related injury. A nurse-led psychological intervention adds significantly to the proportion and magnitude of response.
