    Baryon distributions in ultrarelativistic nucleus-nucleus collisions (1993)
    Springer
    The European physical journal 59 (1993), S. 211-214

    Notes: Abstract We have measured distributions in transverse momentum and rapidity of protons from interactions of 14.6 GeV/nucleon28Si projectiles with targets of Al and Pb. The transverse momentum spectra exhibit a thermal shape with a rapidity dependent temperature parameter. For very central or violent collisions the proton rapidity distributions exhibit the large rapidity shifts and (for Si+Al) a peak at midrapidity as required for full stopping.

    Nutritional and toxicological studies with growing pigs fed aquatic plant rations (1979)

    Notes: Abstract Aquatic weeds from Cayuga Lake in New York were included as 10% or 20% dry weight of rations which were fed to growing pigs for 69 days. The animals gained weight at a rate comparable to those on a basal diet or a diet in which an equivalent weight of alfalfa replaced the aquatic plants. The feed efficiency (kg ration consumed/kg wt gained) of the aquatic rations was significantly lower, probably because of the lower nutritive value of the aquatic plants. Polychlorinated biphenyls (PCBs) were found in the aquatic plants (0.59 ppm, dry weight) and in the pig fat of those fed the aquatic ration. Hepatic microsomal mixed function oxidase activity was not significantly different in the animals fed the various treatment rations. Histopathologic examination of animal tissues revealed no lesions or abnormalities which could be attributed to the diets.

    Notes: Abstract Cabbage, beets, green beans, and butternut squash were grown in control and municipal sewage sludge-treated experimental plots. Freezedried edible portions of each vegetable fed at 25% of the diet to male Fischer rats for 12 weeks, indicated no differences in dietary intake or weight gain, nor were there any differences in blood levels of alpha-fetoprotein, a marker for hepatic preneoplastic transformation. Sludge-grown vegetables did not cause any differences in relative liver weight or in activity of the hepatic mono-oxygenases, aminopyrene-N-demethylase, orp-nitroanisole-O-demethylase, when compared to the same vegetable grown on control soil. There were no effects attributable to the sewage sludge treatment on liver cell ultrastructure. The level of cadmium in the kidneys of rats fed sludge-grown beets was twice that of the controls. The results of mutagenesis testing withS. typhimurium and microsomes (S-9) activation indicated a positive dose response with extracts of sludge-grown beans and in the urine of rats consuming sludge-grown beets. Although no overt toxicologic responses were observed in rats fed sludge-grown vegetables, these positive mutagenic changes create uncertainties in evaluation of potential risks involved in using municipal sludge on food-producing land.

    Toxicologic studies with japanese quail fed winter wheat grown on municipal sludge-amended soil (1984)
    Springer

    Notes: Abstract Winter wheat was grown on soil amended with 100 dry tons per acre (224 metric tons/ha) of municipal sewage sludge from Syracuse, New York. The grain contained 1.43 and 0.98 ppm (mg/kg) dry weight, respectively, of cadmium and nickel. This wheat was incorporated as 60% of a semi-synthetic diet and fed to male and female Japanese quail for two generations. Male quail from the F1 generation fed sludge-grown wheat showed induction of hepatic microsomal enzymes,i.e., aminopyrene-N-demethylase and aniline hydroxylase, that indicated foreign compounds present in the wheat. Cadmium was significantly higher (p 〈 0.05) than controls in kidney, liver, and testes and nickel in the liver of the male quail (F0) fed the sludge-grown grain. Cadmium in kidney and liver (but not in eggs) and nickel in liver was significantly higher (p 〈 0.05) than controls in the females fed the sludge-grown wheat. Birds from the F1 generation showed no significantly different (p 〉 0.05) concentrations of cadmium in kidney, liver, or eggs between the two dietary treatments. There were no observable changes in the tissue ultrastructure of liver and kidney as examined by electron microscopy in any of the treatment groups.

    Notes: Abstract. Rapid progress has recently been made in the identification and characterization of a large number of kinesin and myosin motor proteins. Recent work has uncovered roles for these motors in processes such as vesicle trafficking, cytoskeletal organization, and chromosome movements, to name a few. A series of reviews describing some of the significant advances in our understanding of the structure and function of myosins and kinesins is presented.

    Immunocytochemical analysis of embryonic compartmentation with a monoclonal antibody against a cytokeratin-related antigen (1990)

    Notes: Summary Mab 113F4, a monoclonal antibody recognizing an antigen in the outer synaptic layer of the chick neural retina, also recognizes an antigen appearing in all three germ layers of the gastrulating chick embryo. However, as neurulation proceeds, the antigen is down-regulated in three distinct patterns. First, the antigen is lost specifically from those trunk ectodermal cells destined to form the neural plate and, later, the neural tube. It remains absent from any neural derivative until day 13 when it appears in the outer synaptic layer of the neural retina, coincident with synaptogenesis in this region. Second, the entirety of the head ectoderm loses this antigen as the head lifts off the blastoderm. This down-regulation is followed later by a similar loss of antigen expression in the trunk ectoderm. Third, expression in the mesoderm becomes limited to the lateral plate and extraembryonic epithelia. Endodermal derivatives continue to express the antigen throughout development. Antigen 113F4 is localized within the cytoplasm and is organized in a fibrillar pattern. The intracellular localization of this antigen and its characteristic spatio-temporal tissue distribution are consistent with the antigen being a cytokeratin or cytokeratin-related antigen. The changes in tissue distribution suggest a possible role in tissue modelling in response to inductive interactions during development.

    Particulate dispersion into and within a forest (1974)
    Springer
    Boundary layer meteorology 7 (1974), S. 429-456

    Notes: Abstract Particulate dispersion into and within a 10- to 13-m tall pine forest was studied experimentally at Brookhaven National Laboratory using stained ragweed pollen and other tracers ranging from 14 to 54 Μm in diam. Seventy-two continuous point source releases lasting 20 to 40 min were made at various distances from within the forest edge to 60 m upwind and at heights of 1.75 to 14.0 m. In most experiments, differently colored ragweed pollen was released simultaneously from three locations. Thirty-six longer tests were made using pollen from area sources of ragweed and three with pollen from distant sources. All tests were made during the day with steady winds and unstable lapse rates outside the forest. The sampling network consisted of 119 rotoslide samplers mounted at heights from 0.5 to 21.0 m at 57 positions extending 100 m into the forest. Deposition was sampled by greased microscope slides at each sampling position. Meteorological measurements were taken in and near the forest. Data were classified by particle characteristics; by source type, distance and height; and by meteorological parameters. Isopleths were drawn on scale diagrams of the sampling grid to illustrate concentration patterns. Changes in centerline concentration, crosswind integrated concentration, mass flux, plume width, plume height, deposition, and deposition velocity were related to distance within the forest and other variables. Results were compared to those of similar releases over open terrain and those of previous forest dispersion studies elsewhere. The plume approaching the forest is broadened both vertically and horizontally by increased turbulence at the forest edge and flows mainly into the trunk space and above the forest. Lateral spread is slow within the forest, but vertical spreading beyond the entrance region is greater than in the open. Particles become mixed uniformly below the canopy while appreciable interchange takes place through this layer. Concentration within the forest decreases at a faster rate than in the open, but change in total mass flux within and above the forest is not significantly different. Loss of material takes place by impaction near the forest edge and in the tree tops and by deposition within the forest. Most loss takes place to the foliage rather than the ground, and larger particles are lost faster than smaller ones.
