Französische Bemühungen um Erhaltung des Störbestandes sollten unterstützt werden

Der vereinzelte Fang markierter Störe (Acipenser sturio L.) im Bereich der Deutschen Bucht - die bisher letzte Meldung stammt aus dem Juni 1989 - gibt Anla0, auf französische Bemühungen zur Erhaltung dieses stark vom Aussterben bedrohten "Naturdenkmals" hinzuweisen und die deutsche Fischerei, insbesondere die kleine Hochsee- und Küstenfischerei um Unterstützung der Erhaltungsmaßnahmen zu bitten.

Niedrige Gehalte an toxischen Schwermetallen in Seefischfilet (Ergebnisse der 81. Reise des FFS "Walther Herwig")

Auf der 81. Reise des FFS "Walther Herwig" im März 1987 in die Gewässer östlich Schottlands, Irlands und Nordfrankreichs wurden auf dem Nord-Süd-Schnitt "Westbritische Gewässer-östlicher Kanalausgang nördliche Biskaya" zahlreiche Einzelfischproben für die spätere spurenanalytische Bestimmung der toxischen Schwermetalle Blei und Cadmium gezogen. Bei den Proben handelt es sich um den verzehrbaren Anteil (Muskel, Filet) von kommerziell genutzten Meeresfischen, die den Hols lebend entnommen wurden.

Investigations on the vertical migration of planktonic Crustacea in the Bodensee-Obersee. [Translation from: Schriften des Vereins fur Geschichte des Bodensees und seiner Umgebung, 87, 177-187, 1969.]

The vertical zoning of the planktonic Crustacea in a lake is the expression of a complex set of different factors. Besides the measurable, external influences such as light, temperature, acid and C02 stratification, a particularly large part is played by internal factors, which co-ordinate a specific reaction in each species depending on state of development, age and sex. Supporting this extensive, predictable, annual course of diurnal depths and the daily vertical migrations, whose extent is again dependent on external conditions, primarily of course on the amount of light. The individual factors mentioned, however, are here also of great significance. Within the scope of a long-term study of the planktonic Copepoda of Lake Constance, some day and night series were in 1963 also carried out in the Obersee, in order to obtain at least volumetric data on the extent of the daily migrations of these creatures.

Modulation of the effectiveness of 17-alpha-hydroxy-20-beta-dihydroprogesterone or of a gonadotrophic extract on the in vitro intrafollicular maturation of oocytes of the rainbow trout Salmo gairdnerii by various non-maturing steroids [Translation from: Compte Rendu Hebdomadaire des Seances de l'Academie des Sciences, Paris, Series D 281, 811-814, 1975]

The effectiveness of 17 α-hydroxy-20 β-dihydroprogesterone (17 α-20 β Pg) or of a trout hypophyseal gonadotrophic extract on the in vitro intrafollicular maturation of trout oocytes can be modulated by steroids which do not have a direct maturing effect; the effectiveness of the gonadotrophic extract is lowered by oestradiol and oestrone and increased by testosterone. As these steroids have no significant effect on maturation induced by 17 α-20 β Pg, the site of their activity is probably in the follicular envelopes. Corticosteroids, and Cortisol and cortisone in particular increase the effectiveness of the gonadotrophic extract, but increase the effectiveness of 17 α-20 β Pg even more strongly, suggesting that this 'progestagen' has a direct effect on oocyte sensitivity.

The role of ciliates in the pelagic life cycle of the Mediterranean [Translation from: Rapports et Proces Verbaux des Reunions-Conseil International pour l'Exploration de la Mer 17, 511-512, 1963]

During hydrographic and plankton studies carried out since 1960 in the coastal zone between the Ebro and Castellon (western Mediterranean), data has been collected which confirms the importance of ciliates in the composition and activity of the plankton. The ciliates in 413 samples of 100 ml of water were counted, having been examined with the Utermohl microscope after sedimentation. The samples studied were distributed according to the density of their population. subject for study. The author concludes that recognition of the role of ciliates as an important link in the food chain of the sea would simplify the interpretation of certain problems posed by the nutrition of certain groups of planktonic animals.

Poder Judiciário: Espaço Público de integração entre Direito e Política através dos Movimentos Sociais na Cidade do Rio de Janeiro

Os moradores das Ocupações Zumbi dos Palmares e Quilombo das Guerreiras, no centro da cidade do Rio de Janeiro, se definem como atores sociais que agem segundo representações adquiridas do contexto histórico-social do modo de produção capitalista de fins do século XX. Sob a ideologia de que a qualidade de vida é ser morador no centro da cidade, atuam ilegalmente a fim de pressionar o Poder Público a efetivar políticas públicas de direito à moradia, positivadas na Constituição Federal. Buscam a legitimação dessas condutas e o reconhecimento de suas ações coletivas e de suas identidades no Poder Judiciário, instituição do Estado democrático de direito que se torna espaço público de discussão entre a esfera privada e a esfera pública, cujos limites se reorganizam na crise na pós-modernidade. Investiga-se se a função de intermediador do poder judiciário refere-se a legitimador dessas discussões ou de efetivo solucionador das demandas que lhe chegam. O trabalho conta com três partes: uma prática, onde são descritos as ocupações e os processos judiciais respectivos; uma parte teórica, onde são apresentadas as categorias de pensamentos utilizados para pensar a realidade apresentada na parte prática; e uma terceira parte, de análise da parte prática à luz da parte teórica, a fim de se observar e testar a hipótese construída.
