Influencia del deslamado, dispersante, dosis de colector catiónico en la recuperación de plomo y zinc de minerales oxidados mediante flotación
(Universidad Nacional de TrujilloPE, 2023-10)
Se investigaron los efectos del deslamado #400, silicato de sodio y CMC, como
dispersantes, dosis de colector catiónico A-6494 (hidroxamato) y A-3030C (amina) en la
recuperación de plomo y zinc, respectivamente mediante ...
Materia núcleo de investigación en materiales
(Instituto Tecnológico de Costa Rica, 2018)
Este proyecto pretende iniciar una base sólida para lograr la realización de una materioteca o núcleo de investigación en materiales en el Tecnológico de Costa Rica. Se plantea luego de una ardua investigación de referenciales ...
Modeling of an industrial anaerobic digester: A case study for undergraduate students
(American Society for Engineering Education, Chemical Engineering Division, 2014-01)
An industrial digester is proposed as a case study, aiming at promoting active learning in undergraduate chemical reaction engineering courses. This problem is a good candidate for teamwork in groups of two to four ...
Class and Home Problems: Modeling of an Industrial Anaerobic Digester: A Case Study for Undergraduate Students
(University of Florida, 2014-05)
The traditional approach in undergraduate chemical reaction engineering courses, as practiced in our uni-versity, is typically limited to design problems that can be solved by analytical methods. The study of single reaction ...
Uma contribuição para a avaliação do número de octano de misturas de hidrocarbonetos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2018-05-18)
A new methodology for estimating the octane number of commercial gasolines and intermediate oil refinery streams is presented in this work. Chemical composition as well as physicochemical properties and octane numbers of ...
Neural network modeling of the light profile in a novel photobioreactor
(2014)
An artificial neural network (ANN) was implemented to model the light profile pattern inside a photobioreactor (PBR) that uses a toroidal light arrangement. The PBR uses Tequila vinasses as culture medium and purple ...
Assembly of debranched xylan from solution and on nanocellulosic surfaces
(2014)
This study focused on the assembly characteristics of debranched xylan onto cellulose surfaces. A rye arabinoxylan polymer with an initial arabinose/xylose ratio of 0.53 was debranched with an oxalic acid treatment as a ...

Determination of the diffusion coefficients in the ascorbic acid delivery from nanostructured-polyacrilamide hydrogels
(2006)
In this work the diffusional behavior of water and ascorbic acid (V-C) from a new crosslinked nanostructured polyacrylamide (polyAM) hydrogels is analyzed. The process involves the synthesis of slighlty crosslinked ...
