    Notes: Abstract— Myelin was isolated from bovine optic nerves by differential ultracentrifugation and its lipid composition was analysed. Optic nerve myelin contained 76·3 per cent lipid. The major lipids were cholesterol, ethanolamine glycerophosphatides (EGP) and cerebroside. Serine glycerophosphatides (SGP), sphingomyelin and cerebroside sulphate were present in smaller proportions. EGP and SGP contained 34·6 and 0·5 per cent aldehydes. The major fatty aldehydes were palmitaldehyde, stearaldehyde and octadecenaldehyde. The fatty acids of EGP, SGP and choline glycerophosphatides (CGP) were chiefly 16:0, 18:0 and 18:1, with small proportions of 20 and 22 carbon polyunsaturates. The sphingolipids contained predominantly saturated and monounsaturated fatty acids of chain lengths of 20–26 carbon atoms. Optic nerve myelin and white matter myelin resembled one another closely in overall lipid composition and in the fatty acid compositions of their constituent lipids. Optic nerve myelin and white matter myelin are chemically similar membranes, but both of these differ in their lipid composition from spinal root myelin.

    Notes: Abstract— Cardiolipin (diphosphatidyl glycerol) was isolated from bovine brain grey matter in pure form by column chromatography. A combination of a DEAE cellulose column, an acid-silicic acid column and a bicarbonate-treated silicic acid column was used for the isolation. Analytical data on cardiolipin (and lyso-cardiolipin), including phosphorus and fatty ester values, infrared and ultraviolet spectra, and chromatographic behaviour of intact cardiolipin, lyso-cardiolipin and their water-soluble hydrolysis products gave results which were consistent with the diphosphatidylglycerol structure proposed by MacFarlane. Cardiolipin constituted 1·2 per cent of the total lipids from grey matter, or 0·43 per cent of the dry weight. No aldehydes were detected in purified cardiolipin. The major fatty acids were 16:0, 16:1, 18:1, 18:2 and 20:4. Cardiolipin contained much higher concentrations of 18:2 (17·8 per cent) than any of the other major grey matter glycerophosphatides. Cardiolipin was hydrolysed by incubation with snake venom (Trimeresurus flavoviridis) phospholipase A (phosphatide acyl-hydrolase, EC 3.1.1.4) to determine the distribution of fatty acids on the carbons of its diglyceride moieties. The fatty acids were not distributed randomly; 16:0, 18:0 and 18:2 were predominantly localized in the α and α positions, while 18:1 and 20:4 were predominantly localized in the β and β positions.

    A spatial model of phytoplankton patchiness (1976)

    Notes: Abstract The one-dimensional theory of critical-length scales of phytoplankton patchiness is developed to include phytoplankton growth and herbivore grazing as functions of time and space. The critical-length scale L c for the pathch is then determined by the initial spatial distribution and concentration of the limiting nutrient and herbivores in addition to the daily averaged values of the growth and loss processes. The response of an initial phytoplankton patch to the stresses of turbulent diffusion, nutrient depletion, light periodicity, and nocturnal or continuous herbivore grazing is investigated numerically for several oceanic conditions. Nocturnal grazing, while less stressful on primary production than continous grazing, results in lower phytoplankton standing stocks. Increase in biomass of vertically migrating zooplankton results in a net loss of nutrient which might otherwise be egested, recycled, and utilized in the euphotic zone under continuous grazing conditions. The Ivlev constant is shown via sensitivity analysis to be a significant parameter ultimately influencing phytoplankton production. It is demonstrated numerically that diffusion of phytoplankton cells from areas of high concentration to low concentration prevents the local extinction of the standing stock, thereby rendering a positive herbivore grazing-threshold unnecessary for ecosystem stability.

    Description / Table of Contents: Zusammenfassung Es wird gezeigt, daß der Cornu-Test und der Test mittels des Schiefekoeffizienten anderen Tests vorzuziehen sind, wenn man prüft, ob kleine Stichproben mit weniger als 100 Beobachtungen aus einer Normalverteilung stammen. Das von Cornu verwendete Verhältnis zwischen der mittleren Abweichung und der Streuung ist stark negativ mit dem Exzeßkoeffizienten korreliert.
    Abstract: Résumé On démontre ici que le test de Cornu et celui du coefficient d'obliquité est préférable à tout autre lorsqu'il s'agit d'examiner si de petits échantillons de moins de 100 observations proviennent d'une répartition normale. Le rapport utilisé par Cornu entre l'écart moyen et l'écart quadratique moyen est corélé d'une manière fortement négative avec le coefficient de l'excès.
    Notes: Summary The Cornu criterion and the coefficient of skewness test are shown to be preferable to other tests when testing the hypothesis that small samples, less than 100, have been obtained from a normal population. The Cornu ratio of mean deviation to standard deviation is highly negatively correlated with the coefficient of kurtosis.
