    Notes: Respiratory Activity in Leaves from Herbs in the Tropical Rain Forest.—Plants of the undergrowth flora In the tropical lowland rain forest have typical shade-leaves distinguished by low dry matter percent, large leaf area per gram fresh weight and very low respiratory intensity per unit area of leaf blade. When the respiratory intensity measured at 26°C is converted to 20°C, the values lie somewhat lower than those for extreme shade-leaves of the temperate forests of Denmark. The leaf blades of Lomariopsis guineensis have on the whole the lowest respiratory intensity so far measured in leaf blades: 0.06 mg CO2 per 50 cm2 leaf blade (one side only) and hour at 20°C. The semisucculent shade-leaves of Palisota hirsuta constitute an exception with regard to area per gram fresh weight, in which respect they resemble the semi-succulent shade-leaves of the fern Ophioglossum vulgatum in Denmark.Die Bodenflora von höheren Pflanzen in einem tropischen Regenurwald im Tiefland besteht teils aus Kräutern, teils aus kleinen Bäumen, die eventuell zu grossen heranzuwachsen vermögen; dagegen sind absolut keine Straucher vorhanden. Die Blatter von einigen Kräutern im Urwald bei Adiopodoumé, Elfenbeinsküste, (5°, 20’ nördl. Br, 4°, 10’ west. L) wurden untersucht und zwar folgende: Aframomum sceptrum Schum. (Zingiberaceae), Palisota hirsuta Schum. (Commelinaceae) und Lomariopsis guineensis Kuhn (Farn aus der Familie Polypodiaceae).

    On the validity of the quasi-particle approximation in nuclear physics (1965)
    Springer
    The European physical journal 188 (1965), S. 385-396

    Notes: Abstract The validity of the quasi-particle approximation for the two-point function in nuclear physics is tested by means of one-particle strengths taken from (d, p) reactions. It is found that in general the quasi-particle approximation is not justified.

    Notes: Abstract It is shown that a separable potential represents an interaction acting only in a onedimensional subspace of Hubert-space. Thus the particular rôle played by the collective state in the schematic model is a consequence of the simplifications made in replacing realistic forces by a separable potential.

    Notes: Summary The asymptotic behaviour of the stochastic process $$k \to \frac{1}{k}\sum\limits_{i{\text{ }}\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } {\text{ }}k} {X_i }$$ as k→∞-X ={X i : i=1,2,⋯ being a sequence of independent random variables having mean 0 and positive finite variance, satisfying both Lindeberg's condition and the strong law of large numbers — is studied by means of a distribution invariance principle. This invariance principle sharpens the classical one due to Donsker and Prokhorov describing the “weak” asymptotic behaviour of partial sums of independent random variables on a semi-infinite time interval. The topology of the path space being appropriately chosen it allows to compute the limit distributions of certain functionals associated to X, such as $$X \to \left( {\sum\limits_{i{\text{ }}\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } {\text{ }}n} {EX_i^2 } } \right)^{1/2} \mathop {\max }\limits_{k{\text{ }}\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \geqslant } {\text{ }}n} \frac{1}{k}\left| {\sum\limits_{i{\text{ }}\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } {\text{ }}k} {X_i } } \right|{\text{ (}}n \to \infty {\text{)}}{\text{.}}$$ Moreover, for uniformly bounded variables X i , a general estimate of the rapidity of convergence is derived and applied to various special cases

    Description / Table of Contents: Zusammenfassung Es wird über quantitative photometrische DNS-Messungen an 1500 menschlichen Lymphozyten und Granulozyten mit dem Zeiss Cytophotometer UMSP I nach Feulgenfärbung berichtet. Die Färbungen wurden mit frischem und altem Schiffschem Reagenz durchgeführt. Außerdem wurde das Schiffsche Reagenz mit verschiedenen Pararosanilinpräparaten angesetzt. Wir erhielten eine identische Anfärbung der DNS, wenn das Schiffsche Reagenz noch nicht alt war und wenn das Schiffsche Reagenz mit demselben Pararosanilinpräparat angesetzt wurde. Die Präparate blichen durch Lagerung aus. Die geringste Bleichung erhielten wir bei Verwendung von Schiffschem Reagenz mit einem Pararosanilin acridinfrei von Chroma.
    Notes: Summary The DNA- content of 1500 human lymphocytes and granulocytes was measured with the Zeiss cytophotometer UMSP I after Feulgen staining. The Feulgen staining was carried out with freshly prepared as well as aged Schiffs reagent. In addition we used several batches of Schiffs reagent prepared with various Pararosanilin preparations (Merck, Bayer, Chroma). We got an identical staining of DNA in all samples stained with fresh Schiffs reagent or with Schiffs reagent, prepared from the same batch of Pararosanilin. A fading of the Feulgen stained nuclei was observed after storing the samples for several months. Of all samples the ones stained with Pararosanilin Chroma were most resistant to fading.
