TL;DR: In this paper, the horizontal and vertical joint-sealing members of a curtain wall are used to prevent rain from percolating through the wall, where horizontal members have downwardly directed external flaps which overlie the vertical members at cross-over points of the horizontal members.
Abstract: Sealing joints for curtain walls consisting of juxtaposed panels mounted in a building framework skeleton are provided which comprise horizontal and vertical joint-sealing members which interengage in an overlapping manner so as to prevent rain from percolating through the wall. The horizontal members have downwardly directed external flaps which overlie the vertical members at cross-over points of the horizontal and vertical members.

TL;DR: In this paper, the authors made a initial study about the relationship between the soil contamination by C. tetani and the chemical composition of 82 soil samples from the Estado do Rio de Janeiro (Brasil).
Abstract: The authors made a initial study about the relationship between the soil contamination by C. tetani and the chemical composition of 82 soil samples from the Estado do Rio de Janeiro (Brasil). C. tetani was found in 29.2 % of the samples. No relationship could be demonstrated between the presence of the bacillus and the amount of potassium, magnesium, phosphorus, aluminium and carbon (organic material), as well as the pH of the soil. The microbe was or was not found either in rich soils or in poor ones, as well as in acid, neutral or basic soils. It was found a correlation between the amount of calcium and the positivity of the bacillus. Since many factors may have influenced the results, the authors will study this subject more deeply.

TL;DR: Os resultados obtidos sugerem that o couro de bovinos procedentes de tais regioes pode conter o agente da doenca, mesmo quando os animais estejam em aparente estado de higidez.
Abstract: Examinando 228 (duzentas e vinte e oito) amostras de couro de bovino, os autores identificaram, em 2 (duas) delas, o virus da febrea ftosa tipo “C” Waldmann, sub-tipo “C 3 " Rezende. As amostras foram tomadas de animais procedentes de areas endemicas de febre aftosa, todavia, por ocasiao do abate, nao revelaram qualquer sinal de doenca aparente. Os resultados obtidos sugerem que o couro de bovinos procedentes de tais regioes pode conter o agente da doenca, mesmo quando os animais estejam em aparente estado de higidez.

TL;DR: The germination was directly proportinal to seed size; there was a fall in germination from the first to the last time of testing; the small seeds were the most vigourous; the ambient with 35% of relative humidity was the best on all the tests.
Abstract: O presente trabalho foi desenvolvido no Laboratorio de Sementes do Departamento de Agricultura e Horticultura da E. S. A. «LUIZ DE QUEIROZ», constando de testes de germinacao e de vigor (envelhecimento prococe) realizados em seis epocas bimestrais, com sementes de tres cultivares de soja (Santa Rosa, IAC-2 e Vicoja), de tres tamanhos (Peneira 17-grandes, Peneira 16-medias e Peneira 15 pequenas), conservadas em dois ambientes diferentes: em câmara seca e em ambiente nao controlado. A analise dos dados obtidos permitiu conclusoes como: a germinacao variou entre cultivares e foi diretamente proporcional ao tamanho das sementes; houve decrescimo da germinacao no decorrer do periodo considerado, sendo mais acentuado para sementes pequenas; o vigor foi maior para sementes pequenas; as sementes conservadas em câmara seca superaram as demais em todas as circunstâncias.
