    Notes: The anaesthetic effects of clove-oil-derived eugenol were studied in juvenile rainbow trout, Oncorhynchus mykiss (Walbaum). Acute lethality and the effects of multiple exposures to eugenol were measured. The estimated 8-96 h LC50 for eugenol was found to be approximately 9 p.p.m. Times to induction and recovery from anaesthesia were measured and compared with MS-222 under similar conditions. Eugenol generally induced anaesthesia faster and at lower concentrations than MS-222. The recovery times for fish exposed to eugenol were six to 10 times longer than in those exposed to similar concentrations of MS-222. Clove oil eugenol was determined to be an acceptable anaesthetic with potential for use in aquaculture and aquatic research. Doses of 40-60 p.p.m. eugenol were found to induce rapid anaesthesia with a relatively short time for recovery in juvenile trout.

    Notes: Abstract The activity of various molybdenum oxides supported on a molybdenum foil substrate for the catalysis of propylene metathesis is measured using an isolatable, high-pressure reactor incorporated in an ultra-high vacuum (UHV) chamber which allows samples to be transferred directly from vacuum into the catalytic test chamber. MoO x samples are prepared both by oxidation of metallic molybdenum and reduction of molybdenum trioxide. The results suggest that the presence of an oxygen overlayer on the catalyst inhibits reaction and that the ranking of activity for metathesis at 870 K using 450 Torr of propylene for oxide samples is MoO2〉MoO3〉Mo where MoO2 is ∼ 30 times more active than molybdenum metal under these conditions.

    Notes: Abstract  Several lines of evidence suggest that a defective protein folding is a central event in both Alzheimer’s and prion disease. Although the two disorders are very different clinically, neuropathologically, and biochemically, the molecular event that may trigger the disease process appears to be the same: the formation of an altered protein conformer composed of a high content of β-sheet structure. Compounds with the ability to prevent and to reverse protein conformational changes may be useful as novel therapeutic approaches for Alzheimer’s disease, prion disease, and other disorders of defective protein folding.

    Description / Table of Contents: Zusammenfassung Vorgelegt werden Kartendarstellungen der Feuchttemperatur für Mexiko. Die Bedingungne im Winter und Sommer werden durch Karten für Januar und Juli wiedergegeben. Die Linien der Feuchttemperatur folgen im Allgemeinen der vielgestaltigen Topographie des Landes mit den niedrigsten Werten über Gebirgsgegenden und dem Hochplateau. Es wird der Versuch gemacht, die Ausdehnung der heiss-feuchten Umwelt des Landes durch Anwendung eines einfachen biometeorologischen Index zu berechnen. Die räumliche Verteilung des Diskomfort Index für Mexiko wird für 14:00 hr für die Monate Januar, Mai und Juli gebracht. Sie zeigt die günstige Wirkung der Höhe auf die atmosphärische Umwelt in den nordwestlichen und zentralen Teilen des grossen mexikanischen Plateaus.
    Abstract: Resume On présente ici des cartes de la température du thermomètre mouillé valables pour le Méxique. On y a transcrit les conditions hivernales et estivales an moyen des cartes des mois de janvier et juillet. Les isolignes suivent en général les particularités du relief tourmenté du pays et les valeurs les plus faibles se rencontrent dans les régions de montagne et sur le Haut-Plateau. On essaie en outre de déterminer les régions du pays soumises à une ambiance chaude et humide en utilisant pour cela un indice biométéorologique simple.La répartition dans l'espace de l'indice d'inconfort valable à 14 heures à Mexique est rapporté pour les mois de janvier, mai et juillet. Cette représentation montre l'effet favorable de l'altitude sur l'ambiance générale dans le nord-ouest et le centre du Grand Plateau Méxicain.
    Notes: Abstract Wet-bulb temperature maps for Mexico are presented.Winter and summer conditions are depicted in the January and July maps.Wet-bulb temperature lines reveal in general the rugged topography of the country with lowest values over mountain areas and high plateau. An attempt is made to evaluate the extent of the hot-humid environments in the country making use of a simple biometeorological index. Areal distribution of discomfort index for Mexico is presented for January, May and July at 14:00 hr, showing the favorable effect of altitude on the atmospheric environment in the Northwest and Central portions of the Great Mexican Plateau.

    Notes: Abstract Iodine-129:iodine-127 ratios were determined using accelerator mass spectrometry in 34 Arctic marine algae collected between 1930 and 1993. A smaller set (5) of marine algae were also analyzed mass spectrometrically to determine plutonium-isotope ratios. The 129I:127I ratio increased as much as three orders of magnitude from a mean of 〈1×10−11 (atom/atom) in the pre-nuclear era (before 1945) to nearly 1000×10−11 in 1993 for marine algae collected from the Novaya Zemlya archipelago separating the Barents and Kara Seas. The predominant basis for the higher ratios in the Novaya Zemlya kelps appears to be upcurrent sources of 129I from nuclear fuel-reprocessing facilities at Sellafield (UK) and La Hague (France). Relatively high 241Pu:239Pu ratios (compared to observed bomb fallout at boreal latitudes, decay corrected to the date of collection) also corroborate the influence of non-fallout sources. The small size of the data set precludes determining if there are significant contributions of 129I and other radionuclides from Russian sources. In contrast, marine algae collected between 1969 and 1993 in the Bering, Beaufort and East Siberian Seas had much lower 129I:127I ratios (mean=14.04×10−11±3.15 SD) than those observed in the European Arctic. The narrow range of ratios in Ameriasian Arctic kelps, and the modest change over that time period, indicate that there were no major contributions of non-fallout 129I to North American Arctic surface waters at the time that the algae were collected. The potential for timing the transport of fuel-reprocessed 129I through analysis of additional archived samples is outlined.
