    Notes: Summary: Amino acid composition of protein in oral secretion, which is widely used for construction and maintenance of social wasp nests, was analyzed in pre-emergence nests of Polistes chinensis. More than 20 amino acids were detected from field and laboratory nests, among which glycine, serine, alanine, valine and proline were major amino acids in all samples analyzed. The amino acid composition was very similar among various nest parts, and between field and laboratory nests. Foundresses of P. chinensis produce essentially similar kinds of oral secretion despite variation in their nest sites and in the environment around their nests. The composition of P. chinensis is similar to those so far known among other Polistes species, while different in intergenus comparisons. Amino acid composition of protein in oral secretion may reflect phylogenetical relationships among wasps. The chemical nature of oral secretion, especially the presence of proline in its amino acids, as well as the quantity of secretion production may play an important role to harden their nests. Wasps live their social life on nests which are maintained by such secretion characteristics.

    Notes: Abstract The allocation pattern of proteinaceous resources was estimated in preemergence colonies of Polistes chinensis. Foundresses that nested at exposed sites consumed a larger relative amount of proteinaceous resources to produce oral secretion, which is used for construction and maintenance of nests, than those at sheltered sites. Numbers of immatures reared by foundresses were smaller in exposed nests than those in sheltered ones, and further, workers that emerged from exposed nests were significantly smaller in size than those from sheltered ones. Foundresses had to partition available proteinaceous resources not only among the first batch of the brood but also, before that, between brood nourishment and secretion production in response to given environmental conditions.

    Amino acid composition of the protein in preemergence nests of Polistes (Polistes) riparius, and its similarity to the consubgeneric wasp, P. (P.) chinensis (Hymenoptera: Vespidae) (2000)

    Notes: Abstract Amino acid composition of the protein in the oral secretion, which is widely used for construction and maintenance of social wasp nests, was analyzed in preemergence nests of Polistes (Polistes) riparius. The kinds and proportion (%) of amino acids of the protein detected from nests of P. riparius were very similar to those of a consubgeneric species, P. (P.) chinensis, but were conspicuously different from those of other social wasp genera. Further, it was estimated that protein contents in oral secretion of P. riparius were nearly the same as those of P. chinensis; namely, foundresses of P. riparius, which build much larger nests than those of P. chinensis, did not reduce relative protein contents to produce more oral secretion at a smaller cost. Amino acid composition may reflect phylogenetic relationships among wasp taxa.

    Water circulation in a fringing reef located in a monsoon area: Kabira Reef, Ishigaki Island, Southwest Japan (1998)

    ISSN: 1432-0975
    Keywords: Key words Water circulation ; Fringing reef Monsoonal wind ; Southwest Japan
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences
    Notes: Abstract  Kabira Reef is a well-developed fringing reef situated in a monsoon area where the dominant wind direction changes seasonally: south in summer and north in winter. Circulation in this reef shows a marked wind influence. The circulation pattern under calm wind conditions is characterized by an inflow of ocean waters into the moat over the reef crest and an outflow through a prominent channel. Current vectors change according to wind conditions, and this pattern is weakened and strengthened under southern and northern wind conditions, respectively. We establish a simple model to explain these circulation patterns with two factors: wind and a fundamental circulation pattern under calm conditions. We estimate the ratios of the component of wind to that of the fundamental circulation. The ratios reach 3 and 10 in absolute values under southern and northern wind conditions, respectively. These results can be applied to water circulation throughout the year, with the southern wind-driven circulation dominant in the summer, and the northern wind-driven circulation dominant in the winter. While trade wind conditions often result in a constant circulation pattern, monsoonal wind conditions make the circulation pattern vary according to the seasons.

    Notes: Abstract A two-temperature model is proposed for the semi-inclusive transverse momentum (p T ) distributions at the CERN $$p\bar p$$ collider. Our model accounts well characteristic multiplicity dependence of thep T distributions. Energy dependence of thep T distributions is investigated in comparison with the data at ISR energies. High temperature state becomes more important at high energy and multiplicity regions. The ratio between high and normal temperature is almost independent of energy and multiplicity.

    New scaling of charged particle pseudorapidity distributions at collider energies (1988)
    Springer
    The European physical journal 40 (1988), S. 81-83 
    Details
    ISSN: 1434-6052

    Notes: Abstract A new scaling form is proposed for charged particle pseudorapidity (η) distributions on the basis of scaling in the mean hypothesis. Our new scaling accounts well the recent UA5 data of η distributions in various intervals of charged multiplicity for non single-diffractive events at energies $$\sqrt s = 200$$ and 900 GeV. Similar scaling of inclusive η distributions is theoretically derived, and the validity of this scaling is assured in comparison with the data of ISR and collider energies.

    Description / Table of Contents: Zusammenfassung Der Einfluß des “Sekundär-Minimum” auf die Stabilität von Kolloiden wurde an seifenfreien Polystyrol-Latex-Suspensionen mit einem Durchmesser von 350 mμ bis 1400 mμ untersucht. Die kritische Flockungskonzentration (c. f. c.) und das Zeta-Potential bei c. f. c. wurde mit verschiedenen Salzen bestimmt. Der Wert von c. f. c. ändert sich mit der Teilchengröße. Ein weiterer wichtiger experimenteller Befund ist die vollständige Reversibilität der Flockung bei größeren Latices. Derartige Versuchsergebnisse können durch das Sekundär-Minimum befriedigend erklärt werden.
    Notes: Summary The influence of “secondary minimum” for the stability of spherical colloid has been studied using a series of “soap-free” polystyrene latices from 350 mμ to 1400 mμ in diameter. The critical flocculation concentration (c. f. c.) and the zeta-potential at the c. f. c. for each latex were determined with several salts of different ionic valencies. The values of c. f. c. varied with the particle size, reaching a maximum value at 750 mμ and then decreasing gradually with the diameter. Another phenomenon detected in the experiment was the complete reversibility of coagulation which was observed only in the cases of large size latices, i. e., the coagulates of large size particles were fully redispersed in the solution by stirring. The time-dependence of their sedimentation curves was reproducible. These experimental results could not be explained by the simple theoretical consideration for stability of suspension. The satisfactory explanation is given only using the term of “secondary minimum” of interaction potential, i. e., the origin of coagulation was shifted from the ordinary primary minimum to the shallow “secondary minimum” at about 750 mμ of the particle diameter.

    Notes: Abstract We have measured the electrical resistivity ρ and the thermal conductivity κ of Sr 14−x A x Cu 24 O 41(A = Ca and La) single crystals. The Arrhenius plot of ln ρ vs T −1 gives two kinds of activation energy with a boundary temperature T ρ . The activation energy at T 〈 T ρ is in approximate agreement with the spin gap in the ladder estimated from the NMR measurements, suggesting that holes in the ladder are paired and localized at T 〈 Tρ. The observed κ has been analyzed to be composed of κ ph , κ spin and κ hole due to phonons, spins and holes, respectively. The κ ph exhibits a small peak at ∼ 30 K in every direction of every single-crystal. The contribution of κ spin is observed along the c-axis except for x(Ca) ≥ 6, and the spin gap, which corresponds to the spin excitation from spin-singlet to spin-triplet, has been estimated to be ∼ 420 K. For x(Ca) ≥ 6, the spin gap, which corresponds to the destruction of spin-singlet pairs i. e. the dissociation of hole pairs, has been estimated from κ along the c-axis at T 〉 T ρ to decrease with increasing x(Ca).

    Notes: Abstract This article reports the accumulation effect of the 3He originating from tritium β decay; 3He created in solid remains in it, while one in liquid diffuses and goes out to the vapor gas. We observed this effect through the neutron detection from muon catalyzed fusion phenomenon (μCF), and gave it qualitative understanding, by which the muon transfer rate from (dμ) and (tμ) to helium was derived.

    Notes: Abstract At the RIKEN-RAL Muon Facility, μ- to α sticking K β X-rays were observed for the first time taking advantage of the pulsed beam structure. The precision of the present measurements was insufficient to distinguish between theoretical models, however the observed K β /K α X-ray intensity ratio tends to be smaller than most of these theoretical predictions.
