TL;DR: In this article, a brief account of the geological and hidrogeological characteristics of the Ribeirao Preto region is given, and the feeding, circulation and behaviour of the groundwater are studied by means of geochemistry and environmental isotopes which lead to conclusions which could not be reached with either method used independently.
Abstract: The article starts with a brief account of the geological and hidrogeological characteristics of the Ribeirao Preto region. The feeding, circulation and behaviour of the groundwater are studied by means of geochemistry and environmental isotopes which, used in a complementary way, lead to conclusions which could not be reached with either method used independently.

TL;DR: In this paper, the authors analyzed the interactive patterns of mother-child utterances with regard to the kind and frequency of verbalizations, and the temporal intervals between them, and found that the temporal pattern of mother and child interchanges was characterized by significantly shorter pauses (<2 s) for mothers than for children.
Abstract: The theoretical importance of the linguistic data available to the child in his natural environment has been increasingly emphasized in recent work on child language acquisition. This study sought to describe a portion of such data as contained in maternal verbal behavior and to analyze its influence on the child's usage of speech. The subjects were five 21-month-old children and their mothers. The mother-child verbal interchange was recorded during free-play situations carried out both at the subject's home and in a playroom. The interactive patterns of mother-child utterances were analyzed with regard to the kind and frequency of verbalizations, and the temporal intervals between them. Results showed that the temporal pattern of mother-child interchanges was characterized by significantly shorter pauses (<2 s) for mothers than for children. A variation in this pattern, consisting of pauses longer than 4 s, was associated with certain kinds of ongoing mother-child verbal behaviors. Thus mothers showed selectiveness, in varying degrees, in responding to the child's utterances, and their verbal responses had differential effects on the child's subsequent verbal performance. These effects were described as “initiating”, “maintaining”, or “ending” verbal chains, or else as “non-reacted” utternances. Moreover, the amount of verbalization by the children was positively correlated with the proportion of the mother's output that consisted of immediate responses to the child, and not with the total verbal output.

TL;DR: The author recommends that similar fish-ponds should be built in other northeastern regions as well as in the south, and the obtention of fry through hypophysation method (now used in Israel and Taiwan for Mugilidae) should be replaced, replacing the present method of simply catching youngs measuring 10 to 15 cm total length and putting them in those fish-Ponds.
Abstract: During the spawning period, fishes of the familes Mugilidae and Centropomidae concentrate on the river mouths or brackishwater lagoons. Those species are reared in fish-ponds ("viveiros") in northeastern Brazil, mainly at Pernambuco State. Presently, polyculture trials are made with those species, together with three others of the family Gerridae, with or without artificial feeding or fertilization. The yields are very high per ha /year. A review of the biology of those species, together with the hydrological conditions of the fish-ponds, are presented. The author recommends that similar fish-ponds should be built in other northeastern regions as well as in the south, and the obtention of fry through hypophysation method (now used in Israel and Taiwan for Mugilidae), replacing the present method of simply catching youngs measuring 10 to 15 cm total length and putting them in those fish-ponds. In this way we would contribute to a high and quick production of animal protein, necessary to a great part of Brazilian population.
