    Notes: Abstract: It was recently claimed that lysolecithin (lysophosphatidylcholine) in chromaffin granules is a postmortem artefact. We have, therefore, determined catecholamine/lysolecithin ratios in adrenal tissues and isolated chromaffin granules. In rat adrenals and bovine medulla the ratios in both tissues and granules were similar. This indicates that even in rapidly frozen rat adrenal glands, sufficient lysolecithin is present in the total tissue to account for its presence in isolated organelles. Owing to the high cortex/medulla ratios such studies cannot be performed with guinea pig or rabbit adrenals. However, isolated chromaffin granules from guinea pig, in contrast to a previous study, do contain lysolecithin. We conclude that lysolecithin is an in vivo constituent of chromaffin granules of all species so far investigated.

    Description / Table of Contents: Zusammenfassung Beide Muskelrezeptoren an der Mandibel von Leuctra ziehen vom vorderen Tentorium-Arm zur Mandibel-Basis. Der ventrale Rezeptor besteht aus zwei dünnen Muskelfasern (6 bis 7 μm Durchmesser) und mindestens 10 multiterminalen Sinneszellen, deren Dendriten sich im Innern der Fasern verzweigen und an den Z-Scheiben enden. Der dorsale Rezeptor besitzt drei ähnlich dünne Muskelfasern, aber nur eine einzelne multiterminale Sinneszelle. Ihre Dendriten enden im Ansatzgebiet des Muskels, zwischen Muskelfasern und Epidermiszellen. Beide Rezeptoren haben im wesentlichen denselben Feinbau wie bei Coleopteren, jedoch treten — besonders beim dorsalen Rezeptor — in den Dendriten-Enden Strukturen auf, die den Tubularkörpern bei Mechanosensillen ähneln.
    Notes: Summary The muscle receptor organs of the mandible of Leuctra extend between the anterior tentorial arm and the mandible base. The ventral receptor is composed of two thin muscle fibres (6–7 μm in diameter) and at least ten multiterminal sensory cells, the dendrites of which branch in the interior of the fibres and end near the z-bands. The dorsal receptor organ consists of three muscle fibres of similar diameter and only one multiterminal sensory cell. The dendritic ends lie at the distal end of the muscle, where muscle fibres and epidermal cells make contact. Both receptor organs essentially show the same ultrastructural characteristics as in Coleoptera. However, the dorsal receptor organ in particular possesses organelles in its dendritic ends, which look like the tubular bodies in ciliary mechanoreceptors.

    Notes: Abstract Hua andChen gave estimates of sums $$\sum\limits_{x = 1}^q {e(\mathfrak{F}(x))} $$ wheree(z)=e 2πiz and $$\mathfrak{F}$$ is a polynomial of the typef(x)/q wheref(x)=a k x k +...+a 1 x with integer coefficients having gcd (q, a k ,...,a 1)=1 But no good estimates hold for these sums whenq is small in comparison tok. We therefore consider here a related but different class of polynomials. Special emphasis is given to the cubic case. In subsequent papers of this series we shall deal with cubic exponential sums in many variables and withp-adic and rational zeros of systems of cubic forms.

    Notes: Abstract We study systems of equations $$\mathfrak{F}_1 = \ldots = \mathfrak{F}_r = 0,$$ where $$\mathfrak{F}_1 , \ldots ,\mathfrak{F}_r $$ are cubic forms withp-adic coefficients. Such a system has a nontrivialp-adic solution if the number of variables is at least 50,000 ·r 3. Further we will give estimates for the number of solutions of certain systems of cubic congruences.

    Notes: Abstract It is shown that a system ofr homogeneous cubic equations with rational coefficients has a nontrivial solution in rational integers if the number of variables is at least (10r)5. For most such systems, an asymptotic formula holds for the numberz P of solutions whose components have modulus 〈P.
