    Notes: [Auszug] The decay of these rocks is neither pre-Glacial nor, in the ordinary sense, due to weathering; it is a post-Glacial rotting, usually from a ground-water rich in peat acids. We know that, because boulders (mostly, of course, granite, schist or limy rocks) remain fresh throughout a stiff, impervious ...

    Notes: [Auszug] A SUCCESSFUL fusion reactor calls for much more than the solution of plasma physics problems. This has long been recognised by the American Nuclear Society who have sponsored an important series of 'Topical Meetings on the Technology of Controlled Nuclear Fusion.' The third of the series-The ...

    Notes: [Auszug] Introduction The basic conditions which must be established before a thermonuclear reactor is possible are, first, the containment of a high-temperature gas so that it is isolated from the walls of the surrounding vessel, and second, the attainment of temperatures sufficiently high for nuclear ...

    Notes: [Auszug] DR. L. HAWKES'S1 interesting letter raises wide issues, if (as we believe should be done) the more precise term ‘early Post-Glacial’ be substituted for ‘Pleistocene’. That a tundra condition in Britain succeeded the disappearance of the Pleistocene ice-sheets now seems more than ...

    Notes: Conclusions The experiments clearly show that in a high frequency gas discharge the current is carried in the outer skin of the discharge and the electrical characteristics can be determined using the formulae normally applicable to solid conductors. Over the range investigated it was found that the resistivity was not critically dependent upon either the particular gas used or the pressure.

    Description / Table of Contents: Résumé Les différences de mortalité induites par les produits phytosanitaires entreDelia antiqua et plusieurs organismes antagonistes associés à sa limitation naturelleD. platura (MEIGEN),Coenosia tigrina (F.),Entomophtora muscae (COHK) etAphaereta pallipes (SAY) ont été évaluées dans des conditions simulant celles des cultures. Les mortalités différentes dues à l'action directe ou résiduelle des produits sont décrites pour trois herbicides (Chloro-IPC, Nitrofen et CDAA), trois fongicides (Maneb, Chlorothalonil et Sulfate de Cuivre) et un insecticide (Malathion). Les taux d'application pratique recommandés de ces produits entraînent des différences hautement positives dans les niveaux de mortalité entreD. antiqua et quelques-uns de ses agents de mortalité naturelle. Le Chloro-IPC, herbicide de préplantation et de demi-saison, provoque la mortalité totale d'A. pallipes au-delà des trois jours qui constituent la période test pour les résidus. Des modifications d'orientation comportementale et des modalités de la mort des adultes deD. antiqua infestés parE. muscae ont été aussi notées chez les mouches traitées au Malathion de sorte que la dispersion des conidies était hautement réduite.
    Notes: Abstract Pesticide-induced differential mortality betweenDelia antiqua(MEIGEN)and several other organisms associated with its natural control [D. platura(MEIGEN),Coenosia tigrina (F.),Entomophtora muscae (COHN), andAphaereta pallipes (SAY)] were evaluated under simulated field conditions. Direct and residual differential mortalities were described for 3 herbicides (Chloro-IPC, nitrofen, and CDAA), 3 fungicides (maneb, chlorothalonil, and copper sulfate), and 1 insecticide (malathion). The recommended field application rates of these chemicals produced high positive differential mortality levels betweenD. antiqua and some of the natural mortality agents. Chloro-IPC, a preplant and midseason herbicide, induced 100% mortality ofA. pallipes over the 3-day residual test period. Modifications in behavioral orientation and death patterns ofD. antiqua adults infected withE. muscae were also noted in malathion-treated flies such that subsequent conidial dispersal was highly restricted.

    Notes: An optimized procedure is reported for the analysis of non-volatile compounds from the surface of silica gel high-performance thin-layer chromatography plates. Following chromatography individual compound bands, excised from the plate with their aluminium support and attached to the normal probe target with an electro-conducting adhesive, were ionized by liquid secondary ion mass spectrometry (LSIMS). Several compound types were analysed to assess sensitivity and specificity of detection. Urinary porphyrins provided molecular weight information from subnanomolar amounts. The detection sensitivities of free, glycine-conjugated and taurine-conjugated bile acids were approximately 125 pmol, 100 pmol and 20 pmol, respectively. A 21-component mixture containing oligosaccharide derivatives was used to evaluate the retention of spatial resolution and specificity achievable by the method. Prevention of diffusion with optimal definition of sample bands, avoidance of electrical insulation between matrix and target probe (particularly in negative ion mode) and matrix conditions were important determinants of sensitivity for in situ LSIMS analysis. Irreversible adsorption levels on the silica gel plate were shown to be greater using solvent extraction of compounds from silica removed from the plate than from in situ LSIMS detection.
