Soluciones de Einstein no asintóticamente planas
Soluciones de Einstein no asintóticamente planas 

Alvarado Marín, Rodrigo Eduardo (2011-02-11)
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 ...

Monitoreo ambiental con detectores termoluminiscentes en Costa Rica 

Mora Rodríguez, Patricia; Mora Ramírez, Erick (2009-01-13)
Using thermoluminiscent dosimeters (Harshaw TLD-200) the first set of Costa Rica data on absorbed doses in air from natural radiation is obtained. During the period September 1996 through October 2000 eight different sites ...

Cálculo de las integrales radiales en dispersión de electrones 

Soto Vargas, C. W. (2011-02-11)
The radial integrals which arise from the distorted wave treatment of photon emission process in electron and positron scattering, involve products of the electron`s (or positron`s) ingoing and outgoing wave functions and ...

Curvatura en teorías generalizadas de Yang-Mills 

Chaves, Max (2009-01-13)
The curvature in R1+3 spaces with a generalized Yang-Mills connection is studied and the results are analyzed. Other options borne by modifications of the base space are also studied and commented. The present situation ...

Visualización de plasmas convectivos 

Carboni Méndez, Rodrigo; Páez, Jorge E. (2011-02-11)
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, ...

Control de calidad en espectrometría gamma de bajo nivel 

Salazar Matarrita, Alfonso; Loría Salazar, Luis Guillermo (2011-02-07)
Low level gamma spectrometry is a very precise techniqueto measure the concentration of nuclides present in different samples in Bq kg-1. The quality control of the procedure and method used be carried out by intercomparison ...

Semi- orthogonalities of class of Gauss hypergeometric functions
Semi- orthogonalities of class of Gauss hypergeometric functions 

Bajpai, S. D.; Arora, M. S.; Mishra, Sadhana (2011-02-11)
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.

Aplicación de las técnicas de punto fijo
Aplicación de las técnicas de punto fijo 

Azofeifa Z., Carlos E. (2011-02-15)
This article will develop a computacional procedure for approximating a fixed point of continuos functions of the simplex into itself using the Brouwer`theorem. We also shows the different applications of the theory of ...

Las cuerdas magnéticas 

Chaves, Max (2009-01-13)
The conception of the magnetic string is presented; it is an infinitely thin bundle of magnetic flux lines. They are surrounded by a film of current that rotates around them, and are a solution of Maxwell’s equations. Their ...

Álgebras-MV artinianas y noetherianas
Álgebras-MV artinianas y noetherianas 

Belluce, L. P. (2011-02-11)
We study MV-algebras that satisfacy tha ascending of descending chain conditions on ideals.  We demostrarted, for example, if an MV-algebra is artianan, then it has a finite number of minimal prime ideals. We also show the ...
