A review of the local tectonic frame was made, focusing on the faulting of The Tilaran Ridge and Montes de Aguacate. On a map of faults we plot historic and recent seismicity which was taken from Rojas (1993) and data bases ...

Cardiovascular diseases have been one of the main causes of mortality during the past years in Costa Rica. Many risk factors associated to these disorders include the intake of high-fat diets, being cheese an example of ...

The Radiation Safety Program (RSP) of the University of Costa Rica established in 1990, handles the radioactive waste generated at the University. A centralized storage waste room is used by the Atomic, Nuclear and Molecular ...

The study of the geomagnetic field began with the publication of the book De Magnete (1600) of Sir William Gilbert (1504-1603). By influence of Sir Edmund Halley the British Marine is obligated to make measurements of the ...

In this paper, a theorem id demostrated regarding the imposibility of the existence od asymptotically plane solutions in spaces with static cylindrycal symmetry, in the framework of the General Theory of Relativity, if the ...

We present a study of the evolution of magnetic field in plasmas with different conductivities under the influence of a convective movement independent of time, which allows the description of either a single whirlwind, ...

Until the publication of the book Coloquio... Sobre la materia de la dentadura, y maravillosa obra de la boca by Franco Martínez del Catrillo in 1557, the dental subjet was relegated to an inferior plane below Medicine and ...

A series of porous silicon surfaces were obstained after different exposition times of electrochemiscal etching on crystaline n+- type silicon in presence of hydrofluoric acid. These kind of surfaces show photoluminescence ...

Concepts related to gravitatonal lenses are discussed and applied to develope an interactive visualization tool that allow us to investigate them. Optimization strategies were performed to elaborated the tool. Some results ...

We presented three semi-orthogonalities for a class of Gauss hypergeometric functions. We further employ the semi-orthogonalities to generate a theory concerning finite series expansion involving our hypergeometric functions.
