In the present paper, Sheldon's Somatogram is matematically analyzed in view to the statistical analysis proposed by Carter et al. (1983). The validation of the somatotype dispersion distance (SDD) and the somatotype attitudinal distance (SAD) is cuestionated as the basis…

This paper presents a general image of the coastal landsrape. A description of settlement patterns on the coasts of Tabasco and campeche is presented, based on archeological and historical data, and different types of habitats in the region are classified.,…

In this study we use cointegration methods to investigate the relationship between the variables of the Ohlson model (stock price, earnings per share and book value) with panel data. The cointegration tests were applied at individual and group level (by…

This article is the result of a seminar held by J.J. Parsons, in 1989, at the Institute of anthropological Research of the Nacional University of Mexico. The paper makes reference to an archaeological diagnose of the Basin of Mexico from…

Many of the works dedicated to Zapotec as well as typology suggest that this language possesses a dominant or neutral VSO (verb-subject-object) order. However not all are in agreement, especially because. of particular syntactic behavior and probably for dialectical reasons.…

We describe a technique for using Bode plots in microscopic interferometry, in particular as applied to the three Gaussian beam interferometer recently reported in the literature. The technique is used in a similar manner to its application to an electric…

El trabajo presenta la metodología empleada en el proceso de vigilancia tecnológica y documental que se está llevando a cabo en el seno del proyecto INREDIS. Se argumenta que la vigilancia tecnológica es una tarea cada vez más utilizada por…

En este trabajo se presentan los tres tipos de comportamiento temporal de estrellas de bosones esféricamente simétricas, es decir: configuraciones estables, inestables que colapsan para formar agujeros negros e inestables que explotan. Estas tres posibilidades han sido predichas por la…

In this paper a methodology is presented which allows a quick and simple means of estimating the potential energy that can be obtained from a tidal power plant. The evaluation is made using a normalised nomograph, which is a function…

The unit cell of a graphite crystal is analyzed by using the basic principle of the harmonic oscillator. For this purpose, we consider the atoms that conform the hexagonal unit cell, connected by small springs. The equation of motion of…
