    Notes: Cannulated brown trout, Salmo trutta, were exposed for 36 h to synthetic water with a low calcium content of pH 5 and similar synthetic water dosed with aluminium to raise the filterable A1 from 5 to 290 μg 1−1 over the 36-h period. There were no significant disturbances of plasma concentrations of glucose, cortisol or catecholamine (adrenaline and noradrenaline) in fish held in water of pH 5. The addition of aluminium to this acidic synthetic water resulted in a generalized endocrine stress response with a four-fold increase in plasma glucose concentration after 18 h and a significant increase in plasma cortisol concentration from 24 h onwards when filterable A1 exceeded 200 μg 1−1. Plasma catecholamine concentration indicated an adrenergic stress response in aluminium-exposed brown trout. A transient doubling in noradrenaline after 6 h in A1 was followed by a larger increase in both plasma adrenaline and noradrenaline concentrations in fish surviving the 36-h exposure to A1.

    Notes: Flounders Pleuronectes flesus with an implanted vascular catheter were exposed to a 50% dilution of the water soluble fraction (WSF) of Omani crude oil (c. 6ppm total aromatic hydrocarbons) and serial blood samples taken to determine their endocrine status (cortisol, catecholamines and thyroid hormones) and the resultant and/or causal physiological (haematological, ionoregulatory and respiratory) disturbances. This resulted in a progressive increase in plasma cortisol concentrations from 3 h onwards (rising from 18 to 51 ng ml−1 after 48-h exposure), and increased plasma glucose concentrations indicating a generalized stress response. Plasma T3 and T4 concentrations of both control and WSF-exposed groups declined progressively over the experimental period; exposure to the WSF of crude oil further depressed plasma T4 concentrations but not plasma T3 concentrations relative to those of control fish. Plasma osmolality and sodium and chloride concentrations were stable in WSF-exposed fish, however, plasma potassium concentrations were increased significantly at the 24-and 48-h sampling points. The most profound physiological disturbance in WSF-exposed fish was a dramatic decline in blood oxygen content (CvO2) (from 2–8 to 0–8 ml 100 ml−1 after 48-h exposure), which is likely to be the cause of the increased plasma noradrenaline concentrations from 3 h onwards. Increased noradrenaline is likely in turn to have been responsible for the significant increase in blood haematocrit and blood haemoglobin at the 3-h sampling point, although the dominant effect in the longer-term was a significant decline in both of these haematological parameters.

    Notes: Eulerian frequency spectra were measured in zero-mean-shear (oscillating-grid induced) turbulent flows and were compared with the spectral form proposed by Tennekes [J. Fluid Mech. 67, 561 (1975)]. A satisfactory agreement between the theoretical prediction and experimental results were obtained in a limited frequency range. The empirical constants pertinent to the spectral law, obtained experimentally, were in good agreement with the numerical simulation results. © 1995 American Institute of Physics.

    Notes: An experimental approach to the study of thermal transport in the diamond-anvil high pressure cell is described and the elements of the thermal diffusivity tensor of β-oxygen are reported to a pressure of 9 GPa. The anisotropy in the thermal conductivity is found to be opposite in sense to that in the velocity of acoustic waves. Results are interpreted in terms of a lattice dynamical model in which the strong interactions between an atom and its first-, second-, and third-nearest neighbors are treated in tensorial form with parameters evaluated directly from experiment. © 1996 American Institute of Physics.

    Notes: The spectrum of bound states of He atoms adsorbed on Ag(110) is calculated, using an interaction potential based on effective medium theory EMT for the repulsive term A exp(−bz) and the Zaremba–Kohn form for the attractive van der Waals dispersion term. The electronic charge density of the host in the selvedge region is modeled by superimposing atomic-charge densities using the Herman–Skillman tables and the prefactor A of the repulsive term is fitted to the exact ground state energy obtained from elastic He scattering data. Comparisons are made with the bound-state spectrum extracted from the measured resonances in the He scattering data and with the results of several other models used in the current literature. An assessment of the role played by higher-order dispersion contributions to the attractive potential is also included. © 1996 American Institute of Physics.

    Notes: A comparison was made of the drug costs and nursing dependency of patients undergoing elective cardiac surgery and routine postoperative recovery for two anaesthetic techniques using either propofol with low dose fentanyl or midazolam with high dose fentanyl. Estimates of resource use were based on a randomised clinical trial undertaken at the Northern General Hospital, Sheffield. Times from entry to the intensive care unit until extubation and discharge were recorded for 70 patients and were transformed to nursing shifts. Nursing dependency was calculated on the basis of one nurse per ventilated patient and 0.5 nurse from the start of the shift after extubation. Nursing costs were allocated on the basis of the patient's status at the beginning of each shift in line with the hospital's staffing policy. All drugs used from the morning of the operation until discharge were recorded. Costs of nursing and drugs were calculated. The total cost of patients in the propofol group was 13.3% less than midazolam patients (p = 0.043, for geometric means Cl 0.4% to 27.8%). The clinical study was not designed for economic endpoints; however, it demonstrated achievable savings in propofol-treated patients.

    Notes: The pain from insertion of two small cannulae was compared in 26 volunteers. Each subject was blindfolded and had both a 22G and a 20G cannula inserted in random order. One subject was rejected as cannulation was unsuccessful. Of the remaining 25 subjects, 12 found the 22G more painful and 13 the 20G. This difference was not significant (chi squared p 〉 0.1).

    Notes: Abstract The elastic, thermodynamic, and transport properties of crystals and fluids at high temperature and pressure play a central role in the earth and planetary sciences as well as in a variety of technologies. These properties also constitute a principal experimental constraint on the description of intermolecular interactions at short distances. Aspects of "impulsive stimulated scattering," when adapted to measurements in the diamond-anvil high-pressure cell, provide an approach to the determination of a subset of equilibrium and dynamic properties at high density.
