Interrelated contributions to freshwater science over 78 years: A guide to published work from the Freshwater Biological Association, Institute of Freshwater Ecology and Centre for Ecology and Hydrology, 1929-2006

This article introduces a new listing of published scientific contributions from the Freshwater Biological Association (FBA) and its later Research Council associates – the Institute of Freshwater Ecology (1989–2000) and the Centre for Ecology and Hydrology (2000+). The period 1929–2006 is covered. The authors offer also information on specific features of the listing; also an outline of influences that underlay the research, and its scientific scope.

Observations on the physiological development of trout eggs [Translation from: Roux. Arch. f. Entwicklungsmechanik der Organismen, 114. 771, 1929]

The osmotic pressure of the perivitelline fluid and the yolk of trout (Salmo trutta) eggs were measured separately by the Drucker-Schrein method. The permeability of the egg membrane and the variations in the osmotic pressure of the eggs when placed in salt solutions were also investigated.

Published work on freshwater science from the FBA, IFE and CEH, 1929-2006

A new listing of published scientific contributions from the Freshwater Biological Association (FBA) and its later Research Council associates – the Institute of Freshwater Ecology (1989–2000) and the Centre for Ecology and Hydrology (2000+) is provided. The period 1929–2006 is covered. The compilation extends an earlier list assembled by in 1979.

La Gran Depresión en Europa y en Estados Unidos (1929-1939)

[ES] En el trabajo se realiza un análisis del periodo de entreguerras, centrando su atención en el crack de la bolsa de 1929 y la Gran Depresión que le siguió. Primeramente se encuadra el contexto en la época en la que tuvo lugar, y seguidamente se entra en profundidad en el análisis del crack de la bolsa de valores de Nueva York en el año 1929, sus causas y sus consecuencias. Más tarde se habla sobre la Gran Depresión, explicando sus causas, y finalmente se recogen las consecuencias perversas que tuvo tal hecho.

Habermas e o debate em torno do secularismo: implicações para o lugar da religião na esfera pública

A presente dissertação tem como objetivo principal investigar o conceito de pós-secularismo na filosofia de Jürgen Habermas. Para tanto, buscamos compreender como a religião aparece ao longo da construção do pensamento habermasiano, pontuando as diversas revisões feitas pelo filósofo e suas escolhas metodológicas, que resultaram numa mudança de perspectiva sobre o papel da religião na esfera pública das sociedades contemporâneas. A discussão de Jürgen Habermas se insere num debate mais amplo sobre o reexame do conceito de secularismo, envolvendo não apenas a filosofia, mas a ampla gama das ciências humanas e sociais. Assim, procuramos apresentar o contexto geral desse debate e os principais interlocutores com quem ou contra quem Habermas constrói sua argumentação. Por fim, tentamos mostrar de que maneira as revisões feitas por Habermas nos seus últimos escritos a respeito da religião, bem como a apropriação do conceito de sociedades pós-seculares, se enquadram na moldura geral da teoria habermasiana, principalmente dentro da estrutura do agir comunicativo e da política deliberativa.

Freshwater Biological Association 1929-1979. The first fifty years

Booklet telling the story of the FBA from its founding in 1929 until its Golden Jubilee in 1979. The booklet aimed to produce a readable account of those aspects of freshwater biology that have been among the main themes of the Association's research, as well as some aspects of its history and the philosophy guiding its foundation. The publication includes many images of the FBA's work and history as well as images and illustrations on lake ecology and applied science.
