    Notes: The volume and biochemical composition of amniotic fluid from early normal pregnancies terminated between 8 and 24 weeks were studied. The volume was measured directly in 27 of 33 cases. There was a small, but steady increase between 8 and 11 weeks. From 11 weeks there was a rapid and almost linear increase to a peak volume at 20 weeks. The bilirubin concentration and the optical density difference at 450 mμ. were related to gestational age rather than to the volume of fluid and reached a peak at about 18 weeks. The sodium, potassium and creatinine concentrations were comparable with plasma levels. The urea, glucose, protein and carbon dioxide concentrations were lower, whereas the chloride content was higher than the plasma level. The concentrations of these constituents were not related to either volume or gestational age during the period investigated.

    Notes: Liquor bilirubin concentrations have been measured chemically and spectrophotometrically throughout normal pregnancy in 80 patients and in 30 patients with fetuses affected by rhesus incompatibility.A normal curve and confidence intervals for a single observation of Δ 450 mμ. have been calculated. Prognostic criteria may be applied to gestations earlier than 28 weeks by use of the normal Δ 450 mμ. curve and the curve designating the 0·5 per cent confidence limit.Accurate criteria for intrauterine transfusion cannot be derived from Δ 450 mμ. values before 23–24 weeks and at this stage of pregnancy emphasis should be placed on the obstetric history.

    Notes: Abstract We propose a Veneziano-like model for γγ→VV reactions near threshold involving exchanges of 0− trajectories int- andu-channels. The model is applied to γγ→ωω, ϕϕ, ρϕ, ρω and ωϕ processes. The model in its simplest form cannot account for the disparities in the cross sections for $$\gamma \gamma \to {\rm K}^{ * 0} \bar K^{*0}$$ andK *+ K *− and for γγ→ρ0ρ0 and ρ+ρ−. Further refinements of the model are suggested.

    Notes: Abstract Eleven-kilogram parcels of HY-320 wheat, a cultivar of the new Canada Prairie Spring class, were kept at 15 and 19% initial moisture contents (IMC) in simulated storage in a Manitoba farm granary for 60 weeks to determine biotic and abiotic changes and mycotoxin production. Ochratoxin A reached a maximum of 0.24 ppm by week 20 in the 19% IMC wheat, but was absent in the 15% IMC wheat; no other mycotoxins were detected. Temperature, moisture content, O2 and CO2 levels, fat acidity values, seed germination, microfloral incidence and abundance, and the presence of other mycotoxins were monitored. Principal component analysis of all variables showed that the first principal components accounted for 32–41% of the system variability, and contained the ochratoxin A variable. Ochratoxin A was produced in moist grain that had decreased seed germination andAltermaria activity, and high fungal activity byPenicillium andAspergillus versicolor. Compared to other stored cereals previously studied, HY-320 wheat would be ranked in a low-risk category for mycotoxin formation, based on the ochratoxin A levels observed.

    Notes: Abstract Wheat, barley, and maize, each in 15-kg parcels at 15 and 19% initial moisture content (IMC), were kept in a Bavarian farm granary from June through November 1990. During this period, the grain at each IMC was analyzed for mycotoxins and monitored for grain temperature, carbon dioxide, seed germination, and microfloral incidence and abundance. Barley and maize stored for 20 weeks at 19% IMC contained ochratoxin A in amounts of 70 and 90 μg/kg, respectively. This mycotoxin was not detected in wheat stored at 19% IMC, nor in the grains stored at 15% IMC. Aflatoxin B1, sterigmatocystin, citrinin, and zearalenone were also assayed but not detected in grains stored at either IMC. Principal component analysis of the data indicated that ochratoxin A was produced in a damp niche in maize, when abundant metabolic activity and CO2 production by Penicillium glandicola and Aspergillus spp. were common.

    Climate in relation to deterioration of stored grain (1973)
    Springer
    Oecologia 12 (1973), S. 69-88 
    Details
    ISSN: 1432-1939

    Topics: Biology
    Notes: Summary A hypothesis elucidating the basic relationship between abiotic climatic variates and the deterioration of stored grain by biotic agents was developed for the 41 crop districts in the Prairie Provinces of Canada. Principal component (7 variates measured) and canonical correlation (6 variates measured) analyses were applied to data from each of the 3 crop years (1967–1969), for each of the 3 principal component analyses and for each of the 3 canonical correlation analyses. The data consisted of crop district means of infestation reports from 2522 managers of grain elevators and also of representative meteorological observations from each crop district. The major variates measured were the number of reports of: hot spots, infestations of a) fungus beetles and mites, and b) Cryptolestes ferrugineus (Stephens), and grain fumigants. The climatic variates consisted of mean temperature, precipitation, and number of days above 20° C (68° F) for July, August and September. Three major components, which together explained 64–80% of the variation, indicated broadly similar trends in all analyses. The first component indicated that lower mean temperatures and larger numbers of cool days increased the incidence of fungus-induced hot spots in wet harvested grain. The second component indicated the extent of arthropod infestations: warmer weather increased C. ferrugineus infestation, whereas cooler weather increased infestation by mites and secondary insect species. The third component was a measure of precipitation. Canonical correlation analyses based on 1967 and 1969 data yielded canonical roots that were statistically insignificant at the 1% level. Analyses of 3 external abiotic and 3 biotic response variates based on 1968 data showed that only the first pair of canonical variates was significant, the degree of predictability (R c 2 ) being 56% (P〈0.01). The analyses revealed that lower temperatures, a greater number of cool days, and higher precipitation increased the number of hot spots in 1968 confirming the findings of the principal component analyses. The pattern of hot spot development in relation to climatic characteristics was similar in all crop districts for all years examined. There was a linear relationship between climatic and biotic variates for all these crop districts but the degree of relationship varied geographically. The first and second principal component values for each crop district were ranked and plotted on a climatic map of the Prairie Provinces. The ranking showed that the incidence of hot spots and arthropod infestations was highest in the Sub-boreal and Humid southeastern regions, whereas the incidence was lowest in the Dry Belt region. C. ferrugineus was most common in the Humid southeastern region.

    Population dynamics of stored-product mites (1973)

    Notes: Summary Population fluctuation patterns were determined during 1959–70 in wheat bulks in 2 granaries typical of those used on Manitoba farms for 7 kinds of mites. The patterns were bradly similar in the 2 granaries. Outbreaks of all mites except Tarsonemus granarius and Aëroglyphus robustus were unaffected by the prolonged storage of grain; those of Acarus siro and Cheyletus eruditus occurred in unusually high numbers periodically every 2–5 years, whereas Glycyphagus destructor and Androlaelaps casalis were present in relatively low numbers from the first year of storage. A rise in T. granarius population corresponded with grain age and the succession of microfloral species. Tydeid mites occurred periodically. Pricipal component analyses of up to 26 variates including various fungal species on one grain bulk ecosystem provided a “kaleidoscopic” view of interrelations and dynamics of acarine populations in the grain bulks. The combination of correlated variates of which mites are a part, varied from year to year. Four factors that regulate acarine numbers, particularly those of A. siro and its natural predator C. eruditus, were identified. These are: (i) basic determinants (moisture, temperature, food, and the intrinsic rate of increase of the species); (ii) the main regulator (temperature); (iii) influencers (seed cracks, microflora, dockage, etc.); and (iv) seasonal and cyclic regulators (seasonality in temperature and several density-dependent factors). Generalized diagrams of prey-predator interactions and multivariate interrelations of each kind of mite are presented.
