Marklose nervenfasern im Senium und im Sp�tstadium der Thalidomid-Polyneuropathie: quantitativ-elektronenmikroskopische Untersuchungen

1977

Sural nerve biopsies of four patients, aged 54–76 years, with a predominantly sensory type of neuropathy following high dosages of thalidomide were examined by light and electron microscopy. The present study includes a qualitative and quantitative evaluation of unmyelinated nerve fibers. Despite severe neuropathy, increased numbers of small unmyelinated axons per endoncurial area were noted in all patients. This numerical increase appeared to be independent of aging, since it was not seen in two senile controls, studied at the age of 83 and 88 years. The increase in the endoneurial density of unmyelinated axons, especially of small sized fibers, is likely to be related to regeneration foll…

Die Kontenrahmen einzelner Verkehrszweige

1977

Die betrieblichen Kontenplane, also die Ubersichten der Buchhaltungskonten der Betriebe, sind im allgemeinen an Kontenrahmen ausgerichtet, die ihrerseits von den einschlagigen Wirtschaftsverbanden als Empfehlungen veroffentlicht worden sind. Fur den Verkehrsbereich gibt es jedoch keinen einheitlichen Kontenrahmen, sondern es bestehen fur die einzelnen Verkehrszweige je eigene Kontenrahmen. Um diese besser gruppieren und darstellen zu konnen, ist ein einleitender Uberblick uber die wichtigsten Einteilungsmerkmale von Kontenrahmen nutzlich1).

Fluorescence labelling of organic acidic compounds with 4-bromomethyl-7-methoxycoumarin (Br-Mmc)

1977

4-Bromomethyl-7-methoxycoumarin (Br-Mmc) is introduced as a fluorescence marker for aromatic and heterocyclic acids. To investigate the applicability of this method on substances of different chemical classes, screening experiments with 110 compounds were carried out using a microrefluxer. Most aromatic and heterocyclic monocarboxylic acids gave Mmc-esters which are fluorescent on thin-layer plates, like the Mmc-esters of fatty acids, which have been previously investigated. Strong acids, alcohols, amides and most amines did not react, whereas certain cyclic amines such as piperidine gave strongly fluorescent derivatives. Mmc-phenyl ethers shows only weak fluorescence. A new standard proced…

Zusammenfassung der Diskussion zum Thema: „Die Überwachung des Patienten unter künstlicher Ernährung“

1977

Ist es wichtig, zwischen einer Laktatazetamie (bei Werten von 2–4 mmol/l) ohne Komplikationen und einer Ketonamie etwa gleicher Grosenordnung ohne Azidose zu unterscheiden? Es ist haufig zu beobachten, das Laktat allein oder Ketonkorper allein bestimmt werden und dann Ruckschlusse daraus gezogen werden, ohne das dabei der Gesamt-pH berucksichtigt wird.

Humidity effects on gravitational settling and Brownian diffusion of atmospheric aerosol particles

1977

The dependency on relative humidity of the settling velocity of aerosol particles in stagnant air and of the diffusion coefficient due to Brownian motion of aerosol particles was computed for six aerosol types and different particles sizes in dry state. The computations are based (1) on mean bulk densities of dry aerosol particles obtained from measurements or from the knowledge of the chemical composition of the particles, (2) on micro-balance measurements of the water uptake per unit mass of dry aerosol substance versus water activity at thermodynamic equilibrium, and (3) on measurements of the equilibrium water activity of aqueous sea salt solutions. The results show a significant depend…

Absatz und Absatzpolitik

1977

Der Zugang zu der betrieblichen Funktion Absatz oder, wie gleichbedeutend auch oft gesagt wird, Leistungsverwertung last sich am leichtesten von den Aufgaben und der Stellung der Betriebe ausgehend gewinnen1). Der Betrieb als zielgerichtetes sozio-technisches System ist seinerseits nur Element eines ihm ubergeordneten Systems. Das heist, er lebt in einer Umwelt, mit der ihn Austauschbeziehungen der verschiedensten Art verbinden. Diese Einbettung in eine Umwelt ist fur ihn wesensgemas, denn jeder Betrieb sucht sein Betriebs(Formal)ziel dadurch zu erreichen, das er Leistungen fur Dritte erstellt und sie diesen Dritten anbietet.

The solution polymerization of styrene in methylene dichloride catalysed by trifluoromethanesulfonic acid takes place at a high rate even at low catalyst concentration. The S-shaped course of the conversion curves is explained by a reaction mechanism, in which the catalyst rapidly forms an inactive complex with one monomer molecule, and this monomer-acid complex is in equilibrium with the free catalyst molecule from which the propagating species are formed. Therefore, the formation of active initiating species becomes a slow process which depends also on the change of monomer concentration during polymerization. It is assumed that the active initiating species are formed from two or three m…

1977

Summary Plants of Sinapis alba (white mustard) grown under strong light conditions have a higher content of soluble reducing sugars, of soluble proteins and a higher dry wight during growth from germination to flowering. Furthermore, in these plants the nitrate reductase activity is essentially higher during the vegetative development, but before the beginning of the flowering phase the activity is less than the level of plants grown under low light intensities. The results obtained indicate a direct correlation between nitrate reductase activity and the content of soluble proteins. In the high-light plants both components show distinct maxima 13—14 days after sowing the seeds. The enhancem…

Axial current in extended systems

1977

We establish a connection between the nuclear axial current and pionic properties in the medium. As a strict consequence of PCAC alone, the time component has its matrix elements determined by a wave pion absorption to leading order in the momentum transfer. The properties of the system are governed by scale parameters associated both with its size and with the local interaction structure. Based on this observation we suggest a locality condition for the part of the axial current which has no pion pole. It follows that the full axial current can be explicitly constructed from the local s and p wave pion source functions. A model illustration is presented. Our approach unifies in a model ind…

High-Resolution Spectroscopy in Fast Atomic Beams

1977

Narrow optical resonances have been observed in fast beams of Na and Cs atoms, obtained from ion beams by charge-transfer collisions with Na, K, or Cs. Corresponding to the narrowing of the velocity distribution, occurring by acceleration, the Doppler width along the beam direction is considerably reduced [1, 2].

Synapseudes Shiinoi Riggio, 1973, a Species of Tanaidacea Found in the Mediterranean

1977

During the bionomic survey carried out in the course of 1968 on the biogenic platform bordering the rocky shore of Mount Pellegrino in the Bay of Palermo (northwestern Sicily) some individuals of a species of Synapseudes Miller (1940) were found in samples of Tanaidacea taken during the winter at station no. 1. This find is of considerable interest as no Synapseudes species had hitherto been described from the Mediterranean, although the presence of this genus on the coast of southern France has been mentioned by Bellan-Santini (1962, 1969). Careful examination of the specimens revealed that they belonged to a new species, which was named after Prof. Sueo M. Shiino in gratitude for his kind…

GENETIC AND ENVIRONMENTAL VARIATION IN PERCEIVED EXERTION AND HEART RATE DURING BICYCLE ERGOMETER WORK

1977

The relative contributions of heredity and environment to the variance in heart rate (HR) and rating of perceived exertion (RPE) during the bicycle ergometer work were studied with 14 pairs of male (6 monozygous (MZ) and 8 dizygous (DZ)) and 22 pairs of female (8 MZ and 14 DZ) twins ranging in age from 11 to 20 years. The results showed for both sexes that no significant differences in the intrapair variances of HR and RPE could be observed between the MZ and DZ twin samples. Thus it was concluded that in contrast to several other parameters of the measurements of the physical work capacity HR and RPE are not influenced to any significant degree by the genetic factors.

The Mode of Calcification in Atherosclerotic Lesions

1977

Calcific deposits in atherosclerotic plaques are usually considered to be an end stage of advanced atheroma formation. Postmortem studies of coronary arteries showed that pronounced atherosclerotic calcifications are strongly associated with stenosis of the involved segments and ischemic myocardial lesions (Eggen et al. 1965; McCarthy and Palmer 1974). A close correlation has also been found between calcific lesions detected by fluoroscopy or cinefluorography and clinical coronary artery disease (Oliver et al. 1964; Wartburton et al. 1968). Therefore, arterial calcification detected during life may be of important prognostic significance. Moreover, larger calcific plaques may influence the …

ASPECTS OF THE VALIDITY OF BORG'S SCALE. IS IT MEASURING STRESS OR STRAIN?

1977

Experiments with 10 athletes resulted in close correlations of RPE-scores to strain (heart rate) as well as to stress (work load). The comparison of both relations reveals that in the examined range of stress resp. strain the influence of stress predominates the influence of strain on the perceived exertion.

Crystal Fields in PrX3 (X=In, Tl, Pb, Sn) Intermetallic Compounds with Cu3Au Structure

1977

We have determined the crystal field splittings of Pr3+ in PrIn3, PrTl3, PrPb3, and PrSn3 by inelastic neutron scattering. The values of the deduced crystal field parameters are found to depend strongly on the constituent X, though all systems have nonmagnetic ground-states. The line widths in the different systems are compared.
