    Notes: Molecular dynamics simulations of the photodissociation/recombination process for iodine in liquid xenon at several densities are reported in this paper. These simulations were performed to aid in the understanding and interpretation of recent picosecond experimental investigations on model chemical reaction systems. From these calculations, it was found that geminate recombination occurs primarily within a few picoseconds at all densities considered. This is in agreement with previous molecular dynamics simulations with significantly smaller systems, and with the current interpretation of experimental results. Simulated iodine ground electronic state vibrational relaxation times range from about 1 ns at the lowest density to approximately 250 ps at the highest density reported here. In addition, the functional form of the decay of the average iodine vibrational energy was observed to be nearly independent of density. This result is discussed in terms of simple gas phase isolated binary collision models. Various force correlation functions projected onto the iodine vibrational coordinate were also examined, and indicate that the iodine molecule significantly perturbs the local solvent environment. These force correlation functions may be helpful when assessing the usefulness of liquid phase theories of vibrational relaxation of highly excited molecules. Finally, the simulation results on iodine vibrational relaxation are compared with the available experimental data. These comparisons indicate that the molecular dynamics calculations overestimate the rate of vibrational relaxation over the lower third of the iodine ground electronic state potential surface, and that the efficiency of V–TR transfer, relative to V–V transfer, may have been underestimated. The sensitivity of these results to several system parameters are analyzed.

    Measurements of optical refrigeration in ytterbium-doped crystals (2001)

    Notes: We measured anti-Stokes fluorescence cooling (optical refrigeration) in ytterbium-doped yttrium aluminum garnet (YAG). Pumping the 2.3% Yb3+:YAG crystal with 1.8 W of 1030 nm laser light produced a temperature drop of 8.9 °C from room temperature. The high thermal conductivity and ruggedness of this crystal make it an attractive material for use in optical refrigerators. Our spectral studies show that pure crystals of this material could be efficient for optical refrigeration at temperatures above ∼100 K. Photothermal deflection measurements show that our current crystals can cool at ∼250 K. Additionally, we measured optical refrigeration in a 5% Yb3+:Y2SiO5 crystal when pumped at 1050 nm. © 2001 American Institute of Physics.

    Childhood dysgraphia. Part 2. A study of hand function (1989)

    Notes: Summary Sixty-six children were studied who had presented to the paediatric neurology service over a 2-year period, because they were failing to make the expected progress in mainstream school. Their parents were interviewed with a structured questionnaire and the children had a full neurodevelopmental examination which included a detailed assessment of hand function. Thirty-nine per cent of the children had a specific dysgraphia and there was a male predominance. The different populations of affected children had distinguishing characteristics. A family history of written language skill difficulties was elicited for most of the children with a developmental spelling dysgraphia, but it was uncommon in the children with an acquired spelling dysgraphia or motor dysgraphia. Slow speech development occurred frequently in developmental and acquired spelling dysgraphic children. Mixed handedness was significantly commoner in dysgraphic children who had acquired problems (P 〈 0·05), whereas handedness in the developmental groups was within the expected normal distribution. Aspects of hand function such as power of hand grip did not distinguish the dysgraphic children. However, children with a spelling or motor dysgraphia had speeds of motor performance on successive finger movements and rapid hand pats outwith the normal range. These simple tests are a useful way of examining pertinent handskill difficulties in dysgraphic children.

    Notes: Background  Surgery for undescended testes is recommended before the age of 2 years. However, boys are still undergoing surgery for undescended testes at a much later age than recommended.Methods  An initial audit reviewed all orchidopexies performed at Northampton General Hospital between 1992 and 1994. This demonstrated that only 19% of boys had surgery by the age of 2 years, and the key reason for late surgery was late referral. Guidelines for referral of undescended testes were established in which referral to a surgeon was advised following the 8-month child health surveillance check if undescended testis was suspected. This would enable surgery before the age of 2 years. Audit results were disseminated and we implemented a package of measures based on evidence based change management techniques. These included written advice to general practitioners (GPs), a parent information leaflet and an amended personal child health record advising timing of referral. A reminder to the GP to refer following the 8-month check was generated using computer recall from the Child Health System records. Guideline implementation was monitored by annual audit and feedback.Results  The baseline audit for the years 1992–94 found a median age at surgery of 4 years. Implementation of the new policies in 1998 resulted in a reduction in median age at surgery to 2.0 years in the 12 months ending September 2001.Conclusions  While concern about the age at orchidopexy has been highlighted in many previous studies, this is the first to show that improvement in the age at orchidopexy can be achieved. Implementing locally agreed guidelines with written information to GPs and parents combined with computerized recall from Child Health System records achieved the target within 3 years. Similar systems could be implemented nationally at minimal cost.

    Notes: Summary Summary Twenty-five normal newborns aged between 3 and 6 days had their movements recorded by (a) clinical observation in a controlled environment, (b) chart recording from an automatic movement mattress over 4 hours, and (c) cine photography triggered by the movement mattress. Over 80 different individual types of movement were grouped into six categories: (a) progression movements (obligatory reciprocal movements), (b) symmetrical movements (slower flexion or extension movements), (c) startle movements, (d) asymmetrical tonic neck reflex and ‘Moro’, (e) facial movements and (f) athetoid movements. The normal newborn's motor activity is significantly related to the level of arousal, gestational age, and environmental variables sueh as position, temperature, light and noise.
