    Notizen: In 1983 when The China Quarterly published a special issue on Hong Kong, I attempted to synthesize the history of its urban social life, coining the term “Hong Kong Man” to describe what I considered to be the emergence of an identifiable unique social animal. Hong Kong Man, I suggested, was neither Chinese nor British. I characterized him as quick-thinking, flexible, tough for survival, excitement-craving, sophisticated in material tastes, and self-made in a strenuously competitive world. He operated in the context of a most uncertain future, control over which was in the hands of others, and for this as well as for historical reasons he lived “life in the short term”.

    Notizen: The fifth section of William Carlos Williams's Collected Earlier Poems (1951) bears the title “Della Primavera Transportata Al Morale”; this is also the title of the first poem within that section. A close look, however, reveals a slight discrepancy: “Transportata” at the head of the section is spelt “Trasportata” in the poem title on the page following. A mistake perhaps. And yet, if it is a mistake, it is certainly persistent. On the Contents page at the beginning of the volume the word is also shown as “Trasportata”. Thus of three appearances in the book, the word occurs first without an “n”, becomes “Transportata” in the sectional heading, only to contract again in the poem title to “Trasportata”: the “n” seems to ghost through the text as a flickering shape poised between presence and absence. There is insufficient evidence to decide whether this is deliberate or accidental, or even – if it is accidental – whether the anomaly began with Williams or with his printer, but the history of the poem holds so many parallel variations that it is difficult to doubt that Williams enjoyed the anomaly and wanted to preserve it.

    Notizen: Abstract We report measurements of branching ratios for production of a series of two meson final states in $$\bar p$$ p annihilations at rest in liquid hydrogen. We find: $$\begin{gathered} BR(\bar pp \to \pi ^ + \pi ^ - ) = (3.07 \pm 0.13) \cdot 10^{ - 3} \hfill \\ BR(\bar pp \to K^ + K^ - ) = (0.99 \pm 0.05) \cdot 10^{ - 3} \hfill \\ BR(\bar pp \to \pi ^0 \pi ^0 ) = (6.93 \pm 0.43) \cdot 10^{ - 4} \hfill \\ BR(\bar pp \to \pi ^0 \eta ) = (2.12 \pm 0.12) \cdot 10^{ - 4} \hfill \\ BR(\bar pp \to \pi ^0 \omega ) = (5.73 \pm 0.47) \cdot 10^{ - 3} \hfill \\ BR(\bar pp \to \pi ^0 \eta ') = (1.23 \pm 0.13) \cdot 10^{ - 4} \hfill \\ BR(\bar pp \to \eta \eta ) = (1.64 \pm 0.10) \cdot 10^{ - 4} \hfill \\ BR(\bar pp \to \eta \omega ) = (1.51 \pm 0.12) \cdot 10^{ - 2} \hfill \\ BR(\bar pp \to \eta \eta ') = (2.16 \pm 0.25) \cdot 10^{ - 4} \hfill \\ BR(\bar pp \to \omega \omega ) = (3.32 \pm 0.34) \cdot 10^{ - 2} \hfill \\ BR(\bar pp \to \omega \eta ') = (0.78 \pm 0.08) \cdot 10^{ - 2} \hfill \\ \end{gathered}$$ These are the first measurements of the channels ηη′ and ωη′ and in almost all the other channels are more precise than previous results. We also obtain, in a more precise fashion, the following ratios of branching ratios:K + K −/π+π−=0.323±0.013, π0η′/π0η=0.548±0.056, ηη′/ηη=0.31±0.15, ωη′/ωη=0.515±0.040, π0η/π0π0=0.303±0.010, ηη/π0π0=0.232±0.011 and π0ω/ηω=0.377±0.12. The measurements are made for different η and η′ decays, and we thus obtain Γη→3π 0/Γη→γγ=0.841±0.034, and $$\Gamma _{\eta ' \to \gamma \gamma } /\Gamma _{\eta ' \to \pi ^0 \pi ^0 \eta } = 0.091 \pm 0.009$$ .

    Notizen: Abstract The crystal structure of [NBu 4 n ]f AlI4] has been determined from counter data, and refined by full-matrix least-squares techniques. The crystals belong to the monoclinic space groupP21/n (an alternate setting ofP21/c-C 2h 5 , No. 14) witha=11.661(3),b=20.828(5),c=11.674(3) Å,β=98.39(2)°, andD calc=1.84 g cm−3 forZ=4. The finalR value for 1587 observed reflections is 0.051. The structure consists of discreet [NBu 4 n ]+and [AlI4]− ions. The [AlI4]− anion is approximately tetrahedral and exhibits an average Al-I bond length of 2.52(1) Å. The closest cation-anion, I⋯C, contact is ¯4 Å. The compound was isolated from the reaction of I2 with [NBu 4 n ][Al2Me6I].

    Notizen: Abstract We present an explicit Runge-Kutta scheme devised for the numerical solution ofdelay differential equations (DDEs) where a delayed argument lies in the current Runge-Kutta interval. This can occur when the lag is small relative to the stepsize, and the more obvious extensions of the explicit Runge-Kutta method produce implicit equations. It transpires that the scheme is suitable forparallel implementation for solving both ODEs and more general DDEs. We associate our method with a Runge-Kutta tableau, from which the order of the method can be determined. Stability will affect the usefulness of the scheme and we derive the stability equations of the scheme when applied to the constant-coefficient test DDEu′(t)=λu(t) +μu(t −τ), where the lagτ and the Runge-Kutta stepsizeH n ≡H are both constant. (The caseμ=0 is treated separately.) In the case thatμ ≠ 0, we consider the two distinct possibilities: (i)τ ≥H and (ii)τ〈H.

    Notizen: Summary This paper is concerned mainly with the functional equation (1) $$\sum\limits_{\imath = 0}^m {F_\imath (\alpha _\imath ,x + \beta _i y)} = \sum\limits_{k = 1}^n {G_k (x)H_k (y)} $$ which is a generalization of the Levi-Civita equation (2) $$f(x + y) = \sum\limits_{k = 1}^N {g_k (x)h_k (y).} $$ For complex valued functions of a real variable, Aczél and Chung [1] have shown that (under certain additional natural assumptions) the locally Lebesgue integrable solutions of (1) are exponential polynomials. Jarai [6] has shown that the local integrability assumption can be weakened to measurability. Our aim is to solve distributional analogues of (1) and (2) and thereby obtain another generalization of the result of Aczél and Chung. Essentially, we will show that (1) can be reduced to (2).

    Notizen: Abstract Preorderings and orderings of affine Hjelmslev planes were defined in [3]. The ordering of an AH-plane is shown to induce an ordering on each coordinate biternary ring which is compatible with the multiplication of the associated algebra. Even stronger projective order relations, on both the planes and biternary rings, are introduced and are shown to be also compatible with the ternary operations.

    Beschreibung / Inhaltsverzeichnis: Résumé L'activité endoprotéinase était limitée au liquide de la lumière des régions ventriculaires antérieure et postérieure de l'intestin moyen des larves deCylas formicarius elegantulus Summers. Les aminopeptidases ont été trouvées dans le liquide de la lumière (18%), mais étaient principalement associées avec les fractions insolubles des cellules du ventricule postérieur (82%). Suivant le substrat, l'activité carboxypeptidase était à peu près également répartie entre le liquide de la lumière et les fractions insolubles des cellules du ventricule postérieur. L'amylase, enzyme secrétée, a été observée à la fois dans la lumière antérieure et postérieure. Cinq bandes d'activité amylase ont été révélées sur zymogrammes d'amidon après électrophorèse d'intestins moyens entiers. Trois des bandes d'amylase pouvaient provenir de la plante. Il y avait au moins 2 α-glucosidases, une secrétée et une liée aux cellules du ventricule antérieur. L'activite β-glucosidase était liée aux cellules du ventricule antérieur, fandis que l'activité α-galactosidase était limitée au fluide de la lumière. Les activités β-galactosidase et cellulase ont été trouvées à la fois dans le liquide de la lumière et dans la fraction cellulaire insoluble. Ainsi, la digestion initiale des grosses protéines et des polymères de carbohydrates se produit dans le liquide de la lumière dans les régions ventriculaires antérieure et postérieure. Cependant, l'achèvement de la digestion des oligopeptides se produit principalement dans le ventricule postérieur, tandis que la fin de la digestion des oligosaccharides se produit dans le ventricule antérieur. Les concentrations en inhibiteurs de trypsine de 5 cultivars d'I. batatas L. diffèrent de 1 à 20. Les endoprotéinases deC. formicarius elegantulus ont été inhibées par des extraits de cultivars, mais les cultivars avec des concentrations relativement élevées d'inhibiteur avainent antérieurement montré être susceptibles d'être attaqués par le coléoptère dans des essais en champs.
    Notizen: Abstract Endoproteinase activity was confined to luminal fluid from anterior and posterior ventricular regions of midguts of larvae of the sweetpotato weevil,Cylas formicarius elegantulus (Summers). Aminopeptidase was found in luminal fluid (18%) but was primarily associated with insoluble fractions from cells of the posterior ventriculus (82%). Depending on substrate, carboxypeptidase activity was about equally distributed between luminal fluid and insoluble fractions from posterior ventriculus cells. Amylase was found in luminal fluid in both the anterior and posterior ventriculus. Five bands of amylase activity were detected on starch zymograms following electrophoresis of whole midgut samples. Three of the amylase bands may be plant-derived. At least two α-glucosidases were present, one secreted and one bound to anterior ventriculus cells. β-Glucosidase activity was bound to anterior ventriculus cells whereas α-galactosidase activity was confined to luminal fluid. β-Galactosidase and cellulase activities were found in both luminal fluid and the insoluble cell fraction. Thus, initial digestion of large protein and carbohydrate polymers occurs in luminal fluid in both anterior and posterior ventriculus regions. However, terminal digestion of oligopeptides occurs primarily in the posterior ventriculus while terminal digestion of oligosaccharides occurs in the anterior ventriculus. A 20-fold difference in trypsin-inhibitor concentration was found among five sweetpotato cultivars. Endoproteinases from sweetpotato weevil larvae were inhibited by extracts from the cultivars but cultivars with relatively high concentrations of inhibitor were previously shown to be susceptible to weevil attack in field trials.
