TL;DR: Hatchery production of this species in winter months may help the development of commercial oyster production in southern Chile which is currently limited by summer spatfall.

TL;DR: In this paper, a set of diagrams was proposed to discriminate between calc-alkaline andesites from island arcs and continental margin. But this method may be an appropiate procedure to help in the discrimination between ancient volcanics of both groups.
Abstract: Ti, Zr, Y and P, known to be chemically immobile elements during alteration and metamorphism, have been ploted in a set of diagrams in order to discriminative between calc-alkaline andesites from island arcs and continental margin. This method may be an appropiate procedure to help in the discrimination between ancient volcanics of both groups.

TL;DR: In this article, a two-parameter model for partial segregation is analyzed with respect to the determination of the parameters of the model, and an iterative scheme for the calculations is readily done for a particular system.
Abstract: A proposed two-parameter model for partial segregation is analyzed with respect to the determination of the parameters of the model. An iterative scheme for the calculations is readily done for a particular system. An elementary, bimolecular second order reaction was performed in a premixed perfectly mixed continuous stirred lank reactor. The necessary data are obtained for seven values of the initial concentration of reactants, the parameters of the model calculated from one of the runs, and the other experiments (other values of CB0/CA0) used to check the accuracy of the model. The iterative scheme is found fast and accurate, although an alternative method is discussed. The model appears adequate and the values of the parameters are within permissible ranges.
