Las historias de vida como alternativa para visibilizar los relatos y experiencias silenciadas de la educación

En este artículo se hace referencia a una investigación sobre la constitución de la identidad de docentes en formación y en sus primeros años de trabajo, buscando que emerjan relatos invisibilizados y tratando de aportar otra dimensión de las historias de vida en educación. Una dimensión desde la que hemos pretendido dar cuenta de la complejidad de lo que experiencia el profesorado novel y en formación para generar micro-historias que permitan un relato otro de la historia contemporánea de la educación. En este caso, desde y con el profesorado que comienza en la profesión docente.

Cinética e caracterização físico-química do fermentado do pseudofruto do caju (Anacardium occidentale L.)

The production of cashew apple wine has the purpose of minimizing the wastage in the Brazilian cashew production. Knowing that the cashew apple fermentation produces a good cashew wine, a study of alcoholic fermentation kinetics of the cashew apple and the physico-chemical characterization of the product were made. The cashew wine was produced in an stirred batch reactor. The results of the physico-chemical analysis of volatiles, residual sugars, total acidity and pH of cashew wine showed that their concentrations were within the standard limits established by the Brazilian legislation for fruit wines.

Um novo índice de qualidade das águas para proteção da vida aquática aplicado ao Rio Atibaia, região de Campinas/Paulínia-SP

In this paper a water quality index is developed to subsidize management actions in the Atibaia River for upon protection of aquatic organisms. This index is composed of two measurable environmental parameters normaly, ammonia and dissolved oxygen, the latter representing the contribution of organic matter. Concentrations of these two variables were normalized on a scale from 0 to 100 and translated into statements of quality (excellent, good, regular, bad and very bad). The index was applied to three monitoring points in the Atibaia River and compared to other indices used by the State of São Paulo Environmental Agency (CETESB). The results showed that the degradation in this watershed follows the urban population density. The developed index is more restricted than the other ones routinely used to infer water quality.

Adsorção de aminoácidos sobre minerais e a origem da vida

Minerals adsorb more readily amino acids with charged R groups than those with uncharged R groups, so that the incorporation of amino acids with charged R groups into peptides would be more frequent than that of amino acids with uncharged R groups. However, 74% of the amino acids in the proteins of modern organisms contain uncharged R groups. Thus, what could have been the mechanism that produced peptides/proteins with more amino acids with uncharged R groups than precursors with charged R groups? The lipid world offers an alternative view of the origin of life. In the present paper, several other mechanisms are also discussed.

Justus Von Liebig, 1803-1873. Parte 1: vida, personalidade, pensamento

This first of two papers allusive to the 200th birthday of Justus von Liebig (1803-1873) deals with the origins, life, education, ideas and influence of one of the great 19th century chemists. The principal characteristics of his "Giessen model of teaching research in chemistry" are presented, as well as the role played by many of his students in the evolution of chemical research in various countries. Liebig's strong personality, his controversies, his contribution to the chemical scene in Giessen and Munich are presented. Although few, the connections with Latin-American chemistry are focused.

Análisis de los apoyos que reciben los jóvenes con discapacidad intelectual en su transición a la vida adulta en España: una investigación a partir de experiencias de profesionales y personas con discapacidad = Analysis of support received by young people with intellectual disabilities in their transition to adulthood in Spain: an investigation based on the experiences of professionals and people with disabilities

The objective of this study is to gather information regarding the adaptation of the range of socio educational projects and services aimed at the transition to an adult life of young persons with intellectual disabilities in Spain. The research of the study has been done in three stages. During each stage, a specific tool has been used. One to one in-depth interviews have been undertaken with 45 professionals and 20 individuals with intellectual disabilities. The Delphi method has been applied to two panels consisting of 20 experts each. Firstly, results focus on the approach to different issues related to the devices. Secondly, the training opportunities that these individuals receive to ease the transition period is addressed. And finally, the study refers to the participation of the individuals themselves and their families in the process. The developed analysis allows us to propose strategies to improve the transition to adult life

Estudo do equilíbrio e cinética da biossorção do pb2+ por saccharomyces cerevisiae

The biosorption, based on the use of biomass for removal of ions is distinguished as an innovative and promising technology when compared with the traditional methods. In this context, the aim of the present work is to use Saccharomyces cerevisiae as biosorbent for the retention of Pb2+ metal ions. Factorial design was used for evaluation of the process. The observed equilibrium data were well described by Langmuir and Freundlich adsorption isotherms. The maximum adsorption capacity was 1486.88 mg/g. The results indicated that Saccharomyces cerevisiae is suitable for biosorption of Pb2+ metal ions.

Cinética de redução do catalisador CuO/ZnO/Al2O3

The reduction kinetics of a CuO/ZnO/Al2O3 catalyst by hydrogen was investigated isothermally and by temperature programmed reduction (TPR). Two reducible Cu2+ species were detected; the first one was identified as CuO bulk and the other as Cu2+ strongly interacting with alumina, possibly in the form of copper aluminate. The activation energies for the reduction of these two species were 60 and 90 kJ mol-1, respectively, and the reaction order with respect to hydrogen was one. The isothermal reduction data showed that the isotropic growth model is the most appropriate to describe the reaction rate data for both Cu2+ species.
