Paper production is mainly supported by wood due to its high cellulose content. However, alternative sources are currently being sought to discourage the use of this resource, favoring the protection of resources. The paper consists of a fiber-air gel, obtained from vegetable raw materials that have a considerable amount of cellulose (more than 40% by weight on a dry basis). The main solid constituent of paper is ...

At CEAD Acacias, the entry of personnel is done through manual forms by the guards on duty. It is important to systematize and monitor through an application the entry of personnel to the CEAD facilities (offices, auditorium, modules and laboratories among others). The prototype has the classification of roles of the personnel who request access to any area within CEAD, which can be administrative, teaching, students, ...
Review of yellow corn transportation alternatives to the Avidesa Macpollo S.A plant, Barranquilla-Girón. Colombia.Revisión de alternativas de transporte de maíz amarillo a la planta de Avidesa Macpollo S.A, Barranquilla-Girón. Colombia.
(Sello Editorial UNAD, 2021-01-27)
Formulating a logistic model of transport is of vital importance for companies in order to guarantee the supply of raw materials and the distribution of their products, generating value and making their productive processes more competitive. Taking into account this principle, the objective of this research work was to propose the cost-efficient viability of road transport vs. the Multimodal River-Road, for yellow corn, ...
Implementation of the friction stir processing (FSP) for the modification and reinforcement of aluminum alloys and its effect on the mechanical properties.Implementación de la técnica de fricción agitación (PFA) para la modificación y refuerzo de aleaciones de aluminio y su efecto en las propiedades mecánicas.
(Sello Editorial UNAD, 2021-01-27)
The friction stir processing (FSP) technique can modify the microstructure of metallic materials or form a composite material, generating a grain refinement in the material; modifying it and closing porosities from previous processes, producing new crystallographic textures, altering the mechanical properties of the compound or alloy in the processed zone. In the present work , based on the works of different authors, ...
