A study of flow conditions near the substratum in an experimental channel [Translation from: Verhandlungen der Internationalen Vereinigung fur Theoretische und Angewandte Limnologie 18, 718-725, 1972]

In a slow flow, on a smooth uniform substratum, a limited bed allows the existence of currents slow enough for benthic invertebrates. These conditions rarely occur naturally. The investigations carried out in this work aimed, on an intermediary scale, to define the influence of irregularities in the substratum on flow near the bottom. The substrata used were made of glass marbles. The investigations were carried out in a transparent channel of 70 cm in length and a rectangular section 10 x 5 cm. The data was analysed to study the general evolution of flow in terms of average speeds and the appearance of the turbulence near the bottom.

Fish zoning of some watercourses in Normandy [Translation from: Verhandlungen der Internationalen Vereinigung fuer Theoretische und Angewandte Limnologie 18, 1135-1146, 1972]

The identification of fish zones in western and central Europe has been the objective some major studies. This paper concerns a stream in Normandy specially studied by the author in 1969 and 1970 in the framework of a study on the role of the mean temperature in fish zoning. The paper propounds the comparative study of the morphodynamic and occasionally physico-chemical characteristics, as well as the results of previous sampling by electric fishing of the fish populations of two other streams of the higher Cretaceous layer and supplied by ”chalky” water in Normandy and Picardy.

Report of the Inter-American Tropical Tuna Commission for the year 1972

ENGLISH: The Inter-American Tropical Tuna Commission operates under the authority and direction of a convention originally entered into by the Republic of Costa Rica and the United States of America. The convention, which came into force in 1950, is open to adherence by other governments whose nationals fish for tropical tunas in the eastern Pacific Ocean. Under this provision the Republic of Panama adhered in 1953, the Republic of Ecuador in 1961, the United Mexican States in 1964, Canada in 1968 and Japan in 1970. In 1967 Ecuador gave notice of her intent to withdraw from the Commission, and her withdrawal became effective on August 12, 1968. The Commission held three meetings in 1972: the 26th meeting in Tokyo, Japan, on January 6, 7 and 13; the 27th meeting in Panama, Republic of Panama, on November 7, 8 and 11; and the 28th meeting in San Diego, California, on December 20. SPANISH: La Comisión Interamericana del Atún Tropical está bajo la autoridad y dirección de una convención la cual fue originalmente formada por la República de Costa Rica y los Estados Unidos de América. La Convención, vigente desde 1950, está abierta a la afiliación de otros gobiernos cuyos nacionales pesquen atún en el Pacífico oriental tropical. Bajo esta medida la República de Panamá se afilió en 1953, la República del Ecuador en 1961, los Estados Unidos Mexicanos en 1964, Canadá en 1968 y el Japón en 1970. En 1967, el Ecuador anunció su intención de retirarse de la Comisión y la renuncia se hizo efectiva el 21 de agosto de 1968. La Comisión celebró tres reuniones en 1972: la XXVI reunion en Tokio, Japón, el 6, 7 Y 13 de enero; la XXVII reunión en Panamá, República de Panamá, el 7, 8 Y 11 de noviembre; y la XVIII reunión en San Diego, California, el 20 de diciembre.

Ecological study of the River Lambourn. Report for the period October 1970 to March 1972

A small investigation of the ecology of the river Lambourn was carried out during 1967-70. During this period it became clear that detailed and reliable information could only be obtained by a much larger investigation. The present study was planned to meet the minimum requirements. No pumping is expected during this period and, since the pumping carried out during the pilot scheme was on a small scale, it is reasonable to assume that the river is still relatively unaffected by pumping.The present investigation has two main objectives both of which depend on obtaining a detailed picture of the ecology of the river at the present time. First, it will provide basic information on the state of the river prior to the development of the pumping scheme which will be available for comparison at any later date. Secondly, it may be possible to use some of the data to predict the ecological changes which may occur if the flow of the river is altered by the pumping scheme. This report is part of a series of fives studies on the River Lambourn which were undertaken between 1970 and 1979. [PDF contains 83 pages]

Concentrations of major ions in the stream water of the upper basin of the River Duddon, England, 1972-1974 [Dataset]

This dataset provides raw data of chemical analyses made during studies on seasonal variations of some major ions in the stream water of the upper basin of the River Duddon in Cumbria. Measurements of sodium, calcium, potassium, magnesium and chloride ions and pH were taken at 26 stations in the River Duddon basin between 1972 and 1974.

Formas inter-comunicacionais em Pedro Nava: o signo verbal e o pictórico

Esta pesquisa, contribuindo para os estudos em Literatura Comparada, evidencia a correlação entre Literatura e Artes Plásticas, que tem sido vista desde a Antigüidade quando ícones da analogia entre o verbal e o pictórico deixaram suas marcas na correspondência entre as artes. Tal correlação atravessou vários períodos da História e continua presente em inúmeras pesquisas, na época contemporânea. Este trabalho examina a especificação teórica de vários escritores relacionados ao tema e enfoca principalmente as formas como Pedro Nava (1903-1984) utilizou os artifícios verbal e pictórico ao lidar com duas artes distintas
