En este trabajo se describen los procedimientos aplicados en el rescate, conservación y almacenaje de la colección bioarqueológica del sitio Paso Alsina 1 (Pdo. de Patagones, Prov. de Buenos Aires). Se recuperaron 10 ...

En esta nota se describe el procedimiento usado por los autores para la preparación de extractos y su posterior clean-up, de muestras de agua y material en suspensión del Río de la Plata, para análisis de plaguicidas...

El presente trabajo surge ante una invitación por parte de las autoridades del Departamento de Educación Física para participar de las 3ras. Jornadas de Investigación en Educación Corporal. Tiene como intención dar...

El origen de este proyecto de tesis es la sospecha de que la sociedad argentina enseña a trasgredir. Un aspecto que llamó mi atención desde el comienzo fue cómo vincular la trasgresión con un hecho educativo, circun...

Para evaluar los procedimientos y las sustancias que la población de Comodoro Rivadavia emplea contra la pediculosis en escolares, se analizaron los resultados de 4951 encuestas realizadas entre 2006 y 2007. El 95% de l...

When IBM's John Backus first developed the Fortran programming language, back in 1957, he certainly never dreamt that it would become a world-wide success and still be going strong many years later. Given the oft-repeate...

Macromolecular X-ray crystallography is routinely applied to understand biological processes at a molecular level. However, significant time and effort are still required to solve and complete many of these structures be...

Abstract This paper develops a new approach to the problem of testing the existence of a level relationship between a dependent variable and a set of regressors, when it is not known with certainty whether the underlying...

With its emphasis on practical and conceptual aspects, rather than mathematics or formulas, this accessible book has established itself as the go-to resource on confirmatory factor analysis (CFA). Detailed, worked-throug...

Abstract A DTPA soil test was developed to identify near‐neutral and calcareous soils with insufficient available Zn, Fe, Mn, or Cu for maximum yields of crops. The extractant consists of 0.005 M DTPA (diethylenetriami...

A method has been devised for the electrophoretic transfer of proteins from polyacrylamide gels to nitrocellulose sheets. The method results in quantitative transfer of ribosomal proteins from gels containing urea. For s...

Simultaneous inference is a common problem in many areas of application. If multiple null hypotheses are tested simultaneously, the probability of rejecting erroneously at least one of them increases beyond the pre-speci...

The results of a single-crystal structure determination when in CIF format can now be validated routinely by automatic procedures. In this way, many errors in published papers can be avoided. The validation software gene...
