Problemas del proceso de alimentos provisionales

1982

La doctrina considera el proceso de alimentos provisionales como un proceso declarativo especial y sumario. Habida cuenta de la generalizada crítica doctrinal a la excesiva proliferación de procesos especiales en nuestro ordenamiento, es conveniente plantearse si está justificado mantener este especial cauce para la tutela jurisdiccional del derecho a alimentos o si procedería su reconducción al proceso ordinario.

Ultrastructure and formation of the physogastric termite queen cuticle

1982

0040-8166 (Print) Journal Article; The physogastric termite queen is the most striking example in insects of growth in size without cuticular moulting. This phenomenon has been studied with electron microscopy and histochemical tests in two species of higher termites, Cubitermes fungifaber and Macrotermes bellicosus. The abdominal hypertrophy (physogastry) is allowed by growth of the arthrodial membranes of the swarming imago. The growth is slow (over several years) but important: the cuticular dry weight is multiplied by 20 in C. fungifaber, by 100-150 in M. bellicosus. The termite queen cuticle arises from the transformation of the cuticle of the swarming imago or imaginal cuticle (unfold…

Grundfragen des Mediensystems

1982

Der Begriff Kommunikationspolitik wurde relativ spat in die wissenschaftliche Literatur eingefuhrt (Glotz 1966), obwohl der bezeichnete Sachverhalt so alt ist wie die Massenmedien. Als Beginn der Kommunikations-politik kann man die Auseinandersetzungen zwischen feudalistischem Staat und liberalem Burgertum um die Pressefreiheit betrachten, die aufgrund der Frontenstellung eher als rechtlicher denn als politischer Konflikt erschienen (Ronneberger 1978, I, 181–214). Erst in den liberalen Demokratien wurde die Organisation und Arbeitsweise der Massenmedien unter dem Eindruck ihrer wachsenden Bedeutung fur die politische Willensbildung zum Gegenstand der Diskussion zwischen Parteien, Verbanden …

Physical Aspects of the Atmospheric Aerosol

1982

The atmospheric aerosol is a trace substance of the troposhere as well as the trace gases. Therefore a number of similiarities should be expected. As an example a common model on residence time is developed and discussed in its results. The residence time connects the content of a reservoir (size distribution for aerosols) with its source strength or removal rate. This is presented for the aerosol. In addition other physical properties of the tropospheric aerosol like optical, electrical and water uptake properties are discussed.

Xid-defective male (CBA/N x C57BL/6)F1 accessory cells present bovine insulin to long-term cultured F1-restricted T-cells

1982

The reactivity of H-2b-restricted murine T cells towards bovine insulin was reported to depend on the expression of Ia. W39, a private specificity of I-Ab, on antigen-presenting cells. Cells of male (CBA/N X B6)F1 mice carrying the mutation xid on the X chromosome lack IA. W39 on the cell surface. These cells are unable to present bovine insulin to primed T cells derived from female (CBA/N X B6)F1 mice. We show here that spleen cells of male (CBA/N X B6)F1 hybrids served perfectly as accessory cells for the insulin-dependent induction of a proliferative response of long-term cultured T cells with (B10 X B10.BR)F1 genotype, restricted to recognizing insulin in the context of F1-unique I-A de…

Phagocytosis of erythrocytes in the subarachnoid space at spinal nerve exits

1982

After intracisternal injection of heparinised autologous blood in cats, spinal nerve exits (SNE) of the subarachnoid space (SAS) were examined by scanning and transmission electron microscopy. Phagocytes, erythrocytes and erythrophages (= macrophages which had phagocytosed red blood cells) were found at SNE. Some lining cells of the SAS had retracted from the adjacent cells and had rounded up. Cells which formed an integral part of the subarachnoid lining cells also had phagocytosed erythrocytes. Debris of an exhausted erythrophage was phagocytosed by other macrophages. Finally the observation has been made that erythrophages are capable of leaving the SAS actively by migrating through the …

The lowest β-vibrational phonon in the second minimum of 236,238U

1982

Vibrational exci tat ions of f i ss ion isomers have d i r ec t l y been observed for the f i r s t time using conversion electron spectroscopy. A new experimental setup has been developed whidh allows the measurement of prompt conversion electrons from electromagnetic t ransi t ions in delayed coincidence with the f i ss ion decay of the isomer. The large amount of low energy a-electrons was suppressed by special geometrical arrangement of the detectors in the magnetic f i e l d of the solenoid.

Glykosidintoxikation und deren Behandlung

1982

In den voraufgegangenen Referaten ist mehrfach auf die Bedeutung von Glykosidintoxikationen hingewiesen worden. Sie werden definiert als kardiale und oder extrakardiale, im wesentlichen gastrointestinale und zentralnervose Storphanomene, die durch eine relativ oder absolut zu hohe Glykosidapplikation verursacht sind. Als wesentliches klinisches Kriterium einer glykosidbedingten Verursachung gilt das Abklingen der Symptomatik nach Absetzen der Medikation. Dieses Kriterium hat bei der vielfaltigen Konditionierung der kardialen und extrakardialen Symptomatik naturgemas keine sehr hohe Spezifitat, erst recht keine Signifikanz.

El Lahar Tinguiririca: su significado entre los Lahares chilenos

1982

The Tinguiririca lahar is an example of many similar landforms, which cover large surfaces 60th in andine valleys and the Chilean longitudinal depression. I t is smaller than other ones in Chile, but - at the same time - better conserved, offering good conditions for genetic, kinematic and geochronologic studies, respecting volcanic mudflows. From the genetic and kinematic point of view, the longitudinal lahar profile may be in two parts: a) An upper and middle accumulative area, with concave transverse profile; b) A low accumulative area; whose transverse profile is convexe. These two profiles could be explained by means of braking process in lateral parts, related to central parts, as a f…

RELAXATION METHODS FOR STUDYING MACROMOLECULAR MOTION IN THE BULK

1982

Abstract Macromolecular motion in amorphous and partially crystalline polymers is discussed in the light of recent relaxation experiments with particular emphasis on NMR methods. Polystyrene and polyethylene serve as pertinent examples where a considerable amount of new experimental data provides a bysis for better understanding molecular processes below and above the glass transition, and in the melt.

Neue Urate (I): Vorkommen in Harn- und Prostatasteinen

1982

Neben Harnsaure (Modifikationen I und II) und Harnsaure-dihydrat wurden bisher nur Ammoniumhydrogenurat und Natriumhydrogenurat-monohydrat in Harnsteinen mit Sicherheit nachgewiesen. Obwohl aus Synthesen weitere Salze mit K+, Ca2+, Mg2+ und anderen Kationen bekannt sind, rechnete man kaum mit ihrer Abscheidung in Konkrementen. Nach Erfahrungen mit einigen Tausend Harnsteinanalysen erschien es dem Autor zwar als wahrscheinlich, das gerade die Urate eine grosere Mannigfaltigkeit aufweisen, als dies durch die bisherigen Harnsteinstatistiken belegt wird. Die Aufklarung unbekannter Beimengungen in Harnsteinen ist aber schwierig, wenn sie nicht als Hauptkomponenten, zumindest in Mengen oberhalb v…

Quantitative determination of ochratoxin A in vegetable foods

1982

A simple method for the quantitative determination of ochratoxin A (OA) in rice and other vegetable foods (oatmeal, coconut flakes and peas) is described. This procedure implies an acetonitrile-4% KCl -6N HCl (88+10+2) extraction of the acidic OA, subsequent twodimensional thin-layer chromatography (TLC) and detection by fluorescence after exposure to ammonia fumes (excitation at 340 nm; emission at 475 nm). The quantitative detection limit for OA in rice or coconut flakes is 2.4–4 μg/kg and the recovery is 96%. For oatmeal and peas the detection limit is only 20 μg/kg because of the interference by other metabolites.

XPS structural data and correlation with Mossbauer spectra for Tin-organic compounds: adducts of RnSnCl4-n with 1,2-bis(diphenylphosphino)ethane

1982

Abstract Core level X-ray photoelectron spectra of 1:1 adducts of SnCl4 and RSnCl3 with DPE {[RnSnCl4−n} · DPE (n = 1, R = Me, Bun, Octn, Phn; n = 2, R = Ph; DPE = 1,2-bis(diphenylphosphino)ethane], have been measured in solid phase. The Sn3d 5 2 binding energies, corrected for the Madelung potential at the metal atom, are well correlated with both partial atomic charge on tin, accounting for relaxation upon ionization, and 119Sn Mossbauer isomer shifts. The results are discussed in terms of these molecular parameters.

Neutrinoless double-beta decay in SU(2) x U(1) theories

1982

It is shown that gauge theories give contributions to neutrinoless double-β decay [(ββ)0ν] which are not covered by the standard parametrizations. While probably small, their existence raises the question of whether the observation of (ββ)0ν implies the existence of a Majorana mass term for the neutrino. For a 'natural' gauge theory we argue that this is indeed the case.
