The Oral Cavities of Central European Anuran Larvae (Amphibia)
1982
AbstractWith few additions (structures here called prenarial lobes, prenarial arena pustulations, prevalar pustulations), WASSERSUG'S ( 1976) terminology is adequate to describe the oral structures of Central European anuran larvae. The oral cavities of Bombina and Alytes (Discoglossidoidei) are very similar in structure. Based on oral anatomy Pelabates fuscus appears to occupy an intermediate position within the Anura and a basal position among the Ranoidea, which are morphilogical very heterogeneous in oral characters. This assessment is consistent with the findings of other authors working on the anatomy of the tadpole head. Extensive morphological diversity can be found even within the …

Model ecosystem for environmental transport of xenobiotics
1982
A compartmentalized aquatic-terrestrial flow-through model ecosystem was constructed for studying the transport of agricultural chemicals from the soil to the aquatic environment in soil drainage. Factors were investigated on the fate of reference toxicant,14C-DDT, in the subsystems of the model. The behavior of DDT corresponds to its behavior in natural soil/water systems. The soil, acting as a reservoir, retained most of the DDT. The transportation of DDT to the aquatic compartment was negligible, with low availability to the aquatic biota. Because of the dynamic nature of the model, variation was evident between and within model units.

Increased acetone exhalation induced by metabolites of halogenated C1 and C2 compounds.
1982
Rats were exposed, in a closed desiccator jar chamber, to concentrations of various halogenated C1 and C2 compounds at which the metabolizing capacities were saturated (Vmax conditions). Within the exposure period of 50 h concentrations of the xenobiotic and of exhaled acetone were monitored in the gas phase of the system. The quantitative extent of acetone exhalation was dependent on the individual compound examined. Acetone exhalation was stimulated in presence of vinyl chloride, vinyl bromide, vinyl fluoride, vinylidene fluoride, cis- and trans-1,2-dichloroethylene, trichloroethylene, perchloroethylene, methylene chloride, chloroform, carbon tetrachloride and 1,1,2-trichloroethane. No st…

The Determination of Absorptive Properties of Atmospheric Aerosol Particles Using Photoacoustic Spectroscopy
1982
Chopped light produces an acoustic signal in a closed cell when it is absorbed by a sample of material within this cell. This effect is used to develop a method for measuring the absorption coefficient of aerosol particles. The possibilities and limits of the method are discussed.

Peirce and Greimas from the Viewpoint of Musical Semiotics: An Outline for a Comparative Semiotics
1982
In semiotics it has become more and more evident that the dream of a unified semiotical science is an unreachable ideal. In this situation of extreme heterogeneity it is also legitimate to ask what kind of unifying metatheories one might develop in general semiotics, as well as in its special branches, like that of musical semiotics.
Health care and social welfare in cooperation
1982
The report presents: I) the frames and the reasons for the interrelation and cooperation between social welfare and health care in Finland, 2) the actual research on linkages between municipal social welfare and primary health care service delivery systems. and 3) assessments upon the outcome of cooperation. The report is a part of the international project "Primary Health Care: Cooperation between health and welfare personnel" initiated by the European Centre for Social Welfare Training and Research (ECSW) The expansion of health and welfare services has made it difficult to overview these fields of official responsibility. This is one reason for the demands on cooperation and delegation o…

Chemotherapy for Urinary Bladder Cancer: Developments, Trends, and Future Perspectives
1982
The role of chemotherapy in the management of transitional bladder tumors can conveniently be considered under two principal headings — topical (intracavitary) and sytemic chemotherapy, as the indications for these modalities are distinctly different. The intent of topical administration of cytoxic agents may be (1) prophylactic to prevent recurrences or new occurrences after TUR; (2) curative to clear the bladder of extensive non-resectable multifocal disease, or to control carcinoma in situ.
Quantized ATDHF: theory and realistic applications to heavy ion fusion
1982
The quantized ATDHF theory is reviewed and discussed in the context of the generator coordinate method. This allows for a derivation which does not require an a posteriori quantization process. The ATDHF equations are then solved numerically on a coordinate and momentum grid in fully three dimensional geometry. The theory is applied to various heavy ion systems, where potentials, mass parameters and quantum corrections are evaluated and compared to conventional results from constrained Hartree-Fock. Subbarrier fusion cross sections are calculated and compared with experiment.
The diversity, biomass and production of zooplankton in Lake Inarijärvi
1982
About 650 zooplankton samples were collected from Lake Inarijarvi in 1977–1979 from the littoral and pelagial zones of the lake. One hundred and twenty-three zooplankton taxa were found and most of them can be considered euplanktonic.
Nutrient dependence of phytoplankton production in brown-water lakes with special reference to Lake Päijänne
1982
A method for predicting the mean seasonal chlorophyll a concentration, the mean seasonal in vitro phytoplankton primary productivity per unit volume, the maximum daily production per unit volume and the seasonal integral production in brown-water lakes is presented. The production values can be calculated when the mean annual concentration of total phosphorus and the mean annual colour of the water are known. This method has been developed especially for practical water pollution studies to permit rapid and inexpensive estimates of major biological consequences of changes in effluent loads. The method can be applied for brown-water lakes where phosphorus is the limiting nutrient for primary…

La diferenciación masculino-femenino: Un mito y una realidad
1982
ResumenEl articulo se propone realizar un estudio teorico acerca de las repercusiones psiquicas y sociales de la diferenciacion sexual, tomando como marco de referencia la interpretacion dada por la perspectiva cognitiva a partir del concepto de «esquema basado en la dicotomia del genero».El enfoque cognitivo destaca la importancia que ejerce la identificacion psico-sexual en la adquisicion y desarrollo de las ideas de «masculinidad» y «femineidad». Este proceso de particion del mundo en dos clases sexuales diferenciadas ha resultado doblemente pernicioso tanto para varones como para mujeres, empobreciendo, por un lado, el desarrollo global de la personalidad e impidiendo, por otro, el ente…
Preismanagement für Industriegüter
1982
Als Industrieguter bezeichnen wir Produkte oder Dienstleistungen, deren Abnehmer nicht Endverbraucher, sondern Wirtschaftsunternehmen, offentliche Institutionen oder sonstige Organisationen (z. B. Krankenhauser, Vereine etc.) sind. Industrieguter weisen einige fur das Preismanagement relevante Besonderheiten auf, die wir in diesem Kapitel behandeln. Die Spannweite industrieller Markte ist sehr gros und die Abgrenzung gegenuber Konsumgutermarkten hinsichtlich der preispolitischen Implikationen eher fliesend. So gleicht die Preispolitik fur einfache, standardisierte Industrieguter (z. B. Buromaterial, Personal Computer) derjenigen fur Konsumguter, umgekehrt weisen die preispolitischen Vorgehe…

Antioxidants and carcinogen metabolism
1982
Abstract Supplementation of diet with synthetic antioxidants has been shown to protect animals against a broad spectrum of chemical carcinogens. Some interest has been expressed in the use of these food additives as possible prophylactic agents. However, such considerations appear premature in view of the fact that the protective mechanism has not yet been elucidated. The present communication reviews the effect of antioxidants on carcinogen-metabolizing enzymes, one of the major candidates in the interpretation of the protective antioxidant action.

Die intravesikale Rezidiv-Chemoprophylaxe des oberflächlichen Harnblasentumors
1982
Das oberflachliche Harnblasenkarzinom stellt eine Domane der transurethralen Resektion dar. Das maligne Potential dieser Tumoren ist vergleichsweise niedrig und die betroffenen Patienten leiden oft infolge ihres fortgeschrittenen Alters an zusatzlichen internistischen Grunderkrankungen, die im Vordergrund stehen (1). Andererseits nimmt die karzinombedingte Todesrate in Abhangigkeit vom Infiltrationsstadium und der zellularen Entdifferenzierung deutlich zu. So sinkt die 3-Jahresuberlebensrate von Patienten mit Harnblasenkarzinomen des Stadiums T1–3 mit zunehmender histologischer Entdifferenzierung. Sie betragt bei G1-Tumoren noch 76% und sinkt auf 32% bei G3-Tumoren. Ebenso nimmt die Todesra…
