    Notes: Summary Basal insulin secretion was compared in nine islet-cell antibody positive, non-diabetic first-degree relatives of children with Type 1 (insulin-dependent) diabetes mellitus and nine normal control subjects matched for age, sex and weight. Acute insulin responses to a 25 g intravenous glucose tolerance test were similar in the two groups (243 (198–229) vs 329 (285–380) mU·l−1·10min−1, mean (±SE), p=0.25). Fasting plasma insulin was assayed in venous samples taken at one min intervals for 2 h. Time series analysis was used to demonstrate oscillatory patterns in plasma insulin. Autocorrelation showed that regular oscillatory activity was generally absent in the islet-cell antibody positive group, whereas a regular 13 min cycle was shown in control subjects (p〈 0.0001). Fourier transformation did, however, show a 13 min spectral peak in the islet-cell antibody positive group, consistent with intermittent pulsatility. We conclude that overall oscillatory patters of basal insulin secretion are altered in islet-cell antibody positive subjects even when the acute insulin response is within the normal range.

    Notes: Summary An association between the incidence of childhood Type 1 (insulin-dependent) diabetes mellitus and the average yearly temperature in different countries has been reported, the incidence being higher in countries with a lower mean temperature. We have studied the effect of environmental temperature on the incidence of diabetes in an animal model of Type 1 diabetes, the non-obese diabetic (NOD) mouse. Female NOD mice were divided at weaning, with one group placed at a higher temperature (mean 23.7±1.7° C) and the other at a lower temperature (21.0±1.8° C). At 20 weeks of age 6 of 16 mice at lower temperature and 1 of 17 mice at higher temperature had developed diabetes (p 〈 0.02); at 30 weeks 10 of 16 and 5 of 17 mice had developed diabetes (p 〈 0.05). Non-diabetic animals in the low temperature group had a higher food intake than those in the high temperature group between 13–15 weeks of age (28.0±1.2 g/week vs 24.8± 0.7 g/week, P 〈 0.05). In a parallel experiment, histological examination showed that there were similar degrees of insulitis in the high and low temperature groups at seven weeks of age. We conclude that environmental temperature can affect the incidence of diabetes in the NOD mouse and that this may be related to alterations in food intake.

    Notes: Abstract Aspects of litter movement were looked at in a variety of ways. River bank clearances provided valuable information on litter accumulation and movement, showing a distinctive correlation between flood events and litter movement. Introduction of litter outside of channel deposition (diffuse sources) were limited in the study area in South Wales, UK. A rise in litter deposition occurred for some time after flood events, with the main accumulation occurring in the mid-bank zone. As only some litter types have an increased input during flood events e.g. sewage-derived material from combined sewer outfalls (CSO), accumulation of other litter types, e.g. plastic sheeting could be due to their distribution throughout the catchment. A positive correlation between litter stranding and vegetation was found. During high flows, (75.59 cumecs) litter is removed from sites with little restraining vegetation and deposited where stranding potential is high. Smaller items such as feminine hygiene products were more susceptible to stranding than larger plastic sheeting.

    Notes: The combination of supercritical fluid extraction, high resolution capillary supercritical fluid chromatography, and Fourier transform infrared microspectrometry is described for the separation and identification of polycyclic aromatic hydrocarbons in a coal tar pitch. The variable solvating power of the supercritical fluid was utilized to selectively fractionate the sample. The fluid extract was decompressed through a frit restrictor into the sample cavity of a cooled microvalve injector, where the analytes were deposited and concentrated for subsequent chromatographic analysis. Several of the analytes separated in the chromatograph were collected on a potassium bromide disc at a solvent elimination inter-face for subsequent infrared analysis involving the use of an infra-red microscope accessory. The spectra obtained show the power of this detection technique for distinguishing between isomers.

    Description / Table of Contents: Anwendung der, „Conversion Electron Mössbauer Spectroscopy“ (C. E. M. S.) auf die Untersuchung der Inhibierung der Korrosion in Kondensatorrohren aus MessingBeschrieben wird der Aufbau eines einfachen Zählers zur Aufnahme des „Conversion Electron Mössbauer-Spektrums“ der inneren Oberfläche eines Rohres. Die Zählvorrichtung wird benutzt zur Untersuchung des Einflusses von Eisen-II-Sulfatzusatz als Inhibitor in Kühlwasser für Kondensatorrohre aus Messing. Aufgrund der Ergebnisse führt these Behandlung zur Bildung einer FeOOH-Schicht auf der inneren Rohroberfläche; die genaue Zusammensetzung der Schicht unterscheidet sich geringfügig je nach den örtlichen Verhältnissen.
    Notes: The construction is described of a simple counter for measuring the conversion electron Mössbauer spectrum of the inside surface of a tube. The counter is used to investigate the effects of adding ferrous sulphate to the cooling water of condensers with brass tubes to inhibit corrosion. It is concluded that the treatment leads to the formation on the inside of the tube of a layer of FeOOH, the exact nature of which depends slightly on the local conditions.

    Notes: Certain of the “meta-stable peaks” in mass spectra are abnormally wide. This extra width is shown to be associated with release of kinetic energy during fragmentation. Methods are presented for measuring this energy release and values are given for various transitions in the spectra of aromatic nitro compounds.
