    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 Battelle, Pacific Northwest Laboratories has recently developed, tested and field-demonstrated a technology for the direct assay of transuranic radionuclides (TRU), fission products, and activation products in a variety of radwaste packages generated at commercial nuclear power plants. This technology involves non-destructive passive neutron counting for determination of nanocurie/gram quantities of the TRU radionuclides. Direct gamma spectrometry combined with thermoluminescent dosimetry (TLD) and correlation analysis is also utilized to determine the concentrations of the fission and activation products present in the radwaste packages. Employing counting times of 10 to 20 minutes, a complete analysis of all radionuclides specified for assay by the U.S. Nuclear Regulatory Commission (in 10CFR61) prior to shallow-land disposal of commercial radwastes can be measured at concentrations at least tenfold below the least restrictive Class “A” waste catagory.

    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 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 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 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.

    Notes: β-Galactosidase has been purified from an ammonium sulfate precipitate of E. coli strain ML308 by biospecific adsorption on a column of agarose gel substituted with p-aminophenyl-β-D-thiogalactopyranoside. The system described using a 1.8 liter column has a useful processing capacity of 3.8 × 106 units of β-galactosidase per 2 hr cycle. This corresponds to about 5 g of pure enzyme. An electromechanical timing device operates a set of six solenoid valves and carries out a preset program consisting of sample application, washing, and elation operations.
