    Notes: Biosynthetically labelled Qa-2 antigens were isolated from mouse spleen cells by immunoprecipitation with anti-Qa-2 antisera. When newly synthesized Qa-2 molecules from several different inbred strains were analysed by two-dimensional (2D) gel electrophoresis; four different phenotypes were observed that differed in the number of polypeptides present. The ability to distinguish Qa-2+ phenotypes was used to map the recombination points in two congenic strains, B6. Tlaa and A. Tlab. No alternative Qa-2-like polypeptides were detected in B6.K1 (Qa-2−) cells using a polyspecific rabbit antiserum against mouse class I antigens, but a new molecule was detected in BALB/cBy (Qa-2−) cells. Pulse-chase and surface-labelling experiments showed that some, but not all, of the newly synthesized Qa-2 precursor forms are processed to mature cell surface molecules.

    Notes: Abstract Measurements of incoming global, diffuse and reflected radiation at a tower site in Lake Ontario are used to evaluate components of surface albedo. Albedo for diffuse radiation lies between 0.074 and 0.082 and a coefficient for backscatter from sub-surface water layers shows little deviation from a mean of 0.017. Direct beam albedo for a calm surface follows the Fresnel law. Waves increase direct-beam albedo particularly at higher solar zenith angles. A pronounced dependence of albedo upon zenith angle for clear skies decreases with increasing cloud amount and becomes undetectable in overcast conditions. On a daily basis, albedo ranged between 0.07 in early July to 0.11 in mid-November. Day-to-day scatter is within ±1% of the mean seasonal trend.

    Notes: Abstract Measurements of transient diffusion phenomena are reported for a “high-reactivity”, 20% open-pore volume (OPV), nuclear graphite, in the virgin state and after thermal oxidation in air or radiolytic oxidation in a carbon dioxide/carbon monoxide/methane coolant mixture. The volume of restricted access pores (RAPs) in this graphite is small (〈 5% of the OPV) and the changes in pore structure with oxidation are in general very similar for thermal and radiolytic oxidation. A significant difference is that the RAP volume decreased (as expected) on slow thermal oxidation, but showed a slight increase during radiolytic oxidation. This is consistent with a model in which the methane is severely depleted in RAPs, which are therefore subject to an effectively uninhibited corrosion.

    Notes: Abstract Experimental details are given of a technique for investigating the internal geometry of a porous material, with particular reference to dead-end pores, especially those of the “ink-bottle” geometry (restricted-access pores). The pores of the sample are initially filled with a tracer gas (e.g. methane), and the transient diffusion of the tracer into a carrier gas (e.g. nitrogen) is measured (e.g. by flame ionization detection). Typical results are given, which indicate the potential of the method for studying a key aspect of the pore structure of technologically important materials. Current approaches to the theoretical modelling of the relevant structures are also indicated.

    Notes: Abstract Steady-state and transient gas diffusion measurements are reported for two series of specimens of AGR moderator graphite. One series had been oxidized radiolytically in a coolant atmosphere in the BFB experiments at Grenoble; the other series had been oxidized thermally in air at ∼ 425° C. The evolution of pore structure with oxidation is followed for each series, and in particular, the changes in restricted-access pore (RAP) volume are determined. The results, together with previous data, indicate that thermal oxidation of the gilsocarbon graphite leads to a rapid increase in RAP volume due to the opening up of closed pores. In contrast, radiolytic oxidation leads to a relatively slow growth in RAP volume due mainly to the oxidation of existing RAPs in which the coolant's methane inhibitor is substantially depleted.

    Description / Table of Contents: Zusammenfassung Geringfügige Verschiebungen der allgemeinen Zirkulation führen oft zur Entstehung quasi eines Mosaiks feuchter und trockener Flecken, wobei sich im Mesoscale Dürregebiete bilden. Mit Hilfe der bedingten Wahrscheinlichkeit, an Nachbarstationen gleichzeitig Niederschlagsdefizite festzustellen, wurde eine Methode entwickelt, das räumliche Muster dieser Dürre zu beschreiben. Diese Methode wurde anhand jahreszeitlicher Daten für den Osten North Carolinas (USA) erprobt. Die daraus resultierenden Verteilungsmuster können mit der synoptischen Klimatologie des Gebietes in Beziehung gebracht werden. Im Sommer verzeichnet man zahlreiche kleine Gebiete mit Niederschlagsdefiziten, während in den anderen Jahreszeiten größere Trockengebiete auszumachen sind, die die unterschiedlichen Zugbahnen der Tiefdruckgebiete, Küsteneinflüsse und Regenschatteneffekte widerspiegeln. Ein Vergleich mit dem üblicherweise verwendeten „Palmer Drought Severity Index“ zeigt, daß letzterer nur ausgedehnte Trockenheiten im geeigneten Maß darstellt, die Identifikation von Dürre im Mesoscale jedoch nicht zuläßt. Die vorliegende Methode erlaubt eine Identifikation jener Gebiete, die für mesoskale Dürre predästiniert sind, gibt ein Bild der kausalen Zusammenhänge und schafft damit die Grundlage zur Beobachtung der Entstehung solcher Trokkenheiten.
    Notes: Summary Minor shifts in the pattern of the general circulation frequently result in the development of a mosaic of localized wet and dry patches, creating regions of mesoscale drought. A method of identifying the spatial pattern of such droughts is developed, using the conditional probability of adjacent stations experiencing precipitation deficits simultaneously. The method was tested using seasonal data for the eastern portion of North Carolina, U.S.A. The resulting patterns can be related to the synoptic climatology of the area. Summer reveals numerous small areas of precipitation deficit, while the other seasons have larger deficit areas which reflect changing depression tracks, coastal influences, and rainshadow effects. Comparison of the results with the commonly used Palmer Drought Severity Index indicates that the latter is an appropriate measure only when drought is widespread, and cannot be used to identify mesoscale droughts. The present method allows identification of areas prone to mesoscale drought, suggests causal mechanisms, and provides a basis for monitoring the development of such droughts.

    Notes: Summary Comparisons between observed and modelled values of surface temperature, surface precipitation and 500 hPa height for the current climate were made for the southeast United States. Daily values and analyses pertinent to impact assessment, were emphasized. For the model, the time-independent 10-year series of values developed by the Geophysical Fluid Dynamics Laboratory general circulation model were used. Observations were drawn from records for various stations and decades within the model grid-cell. Cumulative frequency distributions of temperature indicated both more clustering close to the mean and greater extremes for the model. The model reproduced the seasonal cycle of day-to-day temperature variability, but introduced a phase shift of about four months. One result was an apparent overabundance of hot spells in the model results. For precipitation the model indicated twice as many raindays as were observed, about the same number of days when precipitation exceeded 5 mm, and fewer days with amounts exceeding 10 mm, effectively decreasing the probability of heavy precipitation while enhancing annual totals. In winter the model appeared to represent the results from an aggregation of stations within the grid-cell, but in summer it was closer to individual station results. The model reproduced the seasonal cycle in the height and standard deviation of the 500 hPa surface, with a damped amplitude in both cases.
