Research carried out on post-installed structural anchors has shown a link between the embedded length and the diameter of the bore with maximum tensile strength. This paper, is the outcome of research funded by the research department of the Universidad Pedagógica y Tecnológica de Colombia, analyzes this link from the variation of resistance and failure type in structural anchor prototypes with variations in embedded length and drilling diameter, in particular compressive strength 28 MPa, epoxy adhesive, reinforcing bar, 15 graphite units of 0.007 m diameter, and 15 corrugated steel units of 0.0095 m diameter, for a total of 30 systems requested for direct traction in the universal machine. The results showed that tensile strength and failure type are a function of the embedded length and corrugated structure of the anchored reinforcing bar. [ABSTRACT FROM AUTHOR]

This article refers to the analysis of a concrete deterioration agent affectation, known as cycle ice - defrosting, which appears in Tunja at time of frosts. It is explained how the phenomenon qualitative and quantitatively affects the concrete in physical and mechanical properties like porosity, absorption, and resistance, as well as in its physical appearance. In the experimentation stage, a group of 24 cylindrical test tubes of concrete was used. Water/cement relation and type fop curing were used as experimentation variables, with them a distribution matrix was proposed. In order to obtain immediate results, a simulation of this process in an accelerated way was made: concrete parts were taken to frosting periods at night and to defrosting periods during the day, at a continuous time in which two environments were used, an artificial one (refrigerator - low temperature) and a natural one (the environment).

Implementation of horizontal reinforcement in masonry walls with solid cooked clay bricks is a commonly used technique in several countries. This article is intended to analyze masonry walls representatives of Tunja City, with implementation of small steel bars as an alternative of horizontal reinforcement. This study involves definition of types of materials to be used, characteristics of walls to be tested, and variables which should be applied in both walls and during the execution of the diagonal compression test which defines the types of walls with own characteristics of reinforcement. Results from individual and general behavior analysis process of masonry walls subject to diagonal compression tests allow identifying variation of shear stress for each kind of wall, in relation to reinforcement used in several models and failure typology.

The purpose of this research was to standarize the Inventory of Anxiety State - Trait (STAIC) in children and teenagers aged 8 to 15. The standardization of the STAIC questionnaire is the result of the analysis of 670 both male and female children, in 35 public and private schools in the city of Medellín, Colombia. The database was analyzed using SPSS 10.0. The analysis was developed evaluating the structural properties of the test by validating the construct found by factorial analysis with Varimax rotation through the method of main components and the reliability through a Conbrach's alpha with a coefficient of intra-class correlation. The analysis of such conditions brought about six factors in its factorial analysis. A Cronbach's alpha of 0.70 was established as well. Nevertheless, the analyzed sample was taken in the research results were culturally closer to Colombian population rather than Spain population where the test was adaptated. [ABSTRACT FROM AUTHOR]

Se presenta un discurso hecho por Diego Younes Moreno, Exministro de Trabajo y Expresidente del Consejo de Estado de Colombia, con ocasión del foro internacional "Acción de Tutela," celebrado en Bogotá, Colombia en junio de 2004. Se resume la historia de los derechos individuales y las características de la tutela en Colombia. También se describen algunos aspectos polémicos de la acción de tutela en Colombia.
