Cosmic-Ray Anisotropies in Right Ascension Measured by the Pierre Auger Observatory
We present measurements of the large-scale cosmic-ray (CR) anisotropies in R.A., using data collected by the surface detector array of the Pierre Auger Observatory over more than 14 yr. We determine the equatorial dipole ... -
Comprenhensive reparation as a prevailing principle in the responsability of the state –a perspective based on the constitutional court and the Colombian council of state case-law- [La reparación integral como principio prevalente en la responsabilidad del estado –una visión a partir de la jurisprudencia de la corte constitucional y del consejo de estado Colombiano–]
This paper addresses comprehensive reparation as a fundamental right and guiding principle in civil and State liability so that it is taken into account in a prevalent manner when assessing material and immaterial damages ... -
Characterization of titanium powders processed in n-hexane by high-energy ball milling
The effect of speed and milling time on the morphology, crystallite size, and phase composition of Ti Cp powders processed in n-hexane by high-energy ball milling (HEBM) using a E-max Retsch equipment was studied by scanning ... -
Comparison of geometric and experimental models for the assessment of the runout and deposition height of a debris flow in cohesive soils
The objective of this paper is to validate if one dimensional runout and height deposition prediction models are suitable for large-scale landslides (debris flows in cohesive soils) based on a small-laboratory-scale test, ... -
Collaborative creation of a reference architecture for the implementation of data service platforms
Big Data refers to data set whose volume, velocity, and variety make it difficult to capture, manage and process using conventional technologies and tools. This concept is generating new needs in organizations to allow the ... -
Combustion of a hydrogen/carbon monoxide/carbon dioxide mixture in hot and diluted streams
This work presents an experimental investigation on the combustion behavior of a mixture of hydrogen, carbon monoxide and carbon dioxide in hot and diluted streams, like those obtain under flameless combustion regimes. A ... -
Challenge-based learning: A ‘entrepreneurship-oriented’ teaching experience
Challenge-based Learning (CBL) is a pedagogical approach that actively involves students in a realistic, problematic and meaningful situation related to their environment, which requires defining a challenge and implementing ... -
Burning Velocity of Turbulent Methane/Air Premixed Flames in Subatmospheric Environments
The aim of our work was to study turbulent premixed flames in subatmospheric conditions. For this purpose, turbulent premixed flames of lean methane/air mixtures were stabilized in a nozzle-type Bunsen burner and analyzed ... -
Augmented reality and problem-based learning as a strategy that living labs support [La realidad aumentada y el aprendizaje basado en problemas como estrategia que soportan los living lab]
The accelerated changes that the uses of information technologies (IT) have provoked in different social, political, economic, and cultural scenarios in the global sphere have led to an investigation and questioning in ... -

This paper aims to explore the variables that precede the intention and use of Mobile taxi booking (MTB) Apps as tools for taxi drivers to make contact with customers in the city of Medellin, Colombia. A literature review ... -
Assessing school principal leadership practices. Validity and reliability of a rubric [Evaluación de las prácticas directivas en directores escolares: validez y confiabilidad de una rúbrica]
Basic education has several priorities, such as improving students’ levels of reading, calculation, and social interaction; changing pedagogical practices traditionally based on oral expositions and content learning; ... -
Attitude Towards Sport Practice: What Makes an Individual Continued Practice of Sport?
Sport practice is conditioned by different factors; previous studies have shown that the attitude towards physical activity and sports practice is largely conditioned by the individual. This study proposes to examine whether ... -
Aspergillus tubingensis and Talaromyces islandicus Solubilize Rock Phosphate Under Saline and Fungicide Stress and Improve Zea mays Growth and Phosphorus Nutrition
The purpose of this study was to evaluate the capability of Aspergillus tubingensis and Talaromyces islandicus to solubilize inorganic phosphorus sources, their activity under abiotic stress, and the enhancement of P ... -
Analytical formulation of the stiffness method for 2d reticular structures using green functions
Green functions (F.G.) are defined as the response of a medium to a unit point load and are widely used to solve boundary value problems. Unfortunately, in structural analysis, its use is limited and they are only used ... -
