Ethylene Hydrogenation Molecular Mechanism on MoCy Nanoparticles
Ethylene hydrogenation catalyzed by MoCy nanoparticles has been studied by means of density functional theory methods and several models. These include MetCar (Mo8C12), Nanocube (Mo14C13), and Mo12C12 nanoparticles as ...
Influence of the milling conditions on the compressive strength of Ti/TiC composite materials sintered at atmospheric pressure
High compressive strength composite materials based on commercially pure titanium were synthesized from Ti Cp grade 2 powders processed by high-energy ball milling using n-hexane as PCA and subsequent sintering in a tubular ...
Validation of the accuracy of the CHIRPS precipitation dataset at representing climate variability in a tropical mountainous region of South America
This study aims to validate the accuracy of the Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) dataset at representing climate variability over various time scales. The study is carried out in Antioquia, ...
Numerical Investigation of Operating Conditions that Lead to Flat Flames, Flashback, and Blowout in A Surface-Stabilized Combustion Burner
Surface-stabilized combustion burners or surface-radiant burners use perforated ceramic plates, ceramic foams, or metal fibers to stabilize a premixed flame. These burners are the most straightforward alternative to have ...
Assessment of Curriculum Design by Learning Outcomes (LO)
This paper analyzes the assessment experience as part of curriculum design by learning outcomes of the Master in User Experience Design of the Universidad Nacional Abierta y a Distancia—UNAD Colombia and the University of ...
Irony, parrhesía, cynicism and post-truth as deployments of discourse intent
The paper, by means of a hermeneutic method supported by documentary review, states that, takin intent into consideration, it is no possible a discourse simultaneously political and ironic. It has five sections: first, an ...
Development of a Chatbot with NLP for the Prefecture of Los Rios in Ecuador
The coronavirus has prevented face-to-face consultations of procedures in the entities, so Ecuadorian companies have opted to use technological tools to provide smooth service to their customers. Among them is the Chatbot, ...
Demand Response Program Implementation Methodology: A Colombian Study Case
The industrialization and urbanization are responsible for Greenhouse Gas (GHG) emissions and could generate energy shortage problems. The application of Demand Response (DR) programs enables the user to be empowered towards ...
