(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA PRODUÇÃOPrograma de Pós-Graduação em Engenharia de ProduçãoUFMG, 2018-12-20)
In the Integrated Uncapacitated Lot Sizing and Bin Packing problem we have to couple
lot sizing decisions of replenishment from single products suppliers with bin packing
decisions in the delivering of client orders. A ...
Effect of pH of colloidal suspension on crystallization and activation energy of deep levels in SnO2 thin films obtained via sol-gel
(Pergamon-Elsevier B.V. Ltd, 2009-09-01)
Colloidal suspensions of tin dioxide (SnO2) are prepared by the sol-gel method from suspensions with distinct pHs. The particles in solution are embedded by an electrical layer. Decreasing the pH contributes to the destruction ...

Morphology and topography analysis of mesoporous titania templated by micrometric latex sphere arrays
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this work, mesoporous titania is prepared by templating latex sphere arrays with four different sphere diameters at the micrometric scale (phi > 1 mu m). The mesoporous titania homogeneously covers the latex spheres ...
Establishment of Constraints on Amyloid Formation Imposed by Steric Exclusion of Globular Domains
(Academic Press Ltd - Elsevier Science Ltd, 2018-10)
In many disease-related and functional amyloids, the amyloid-forming regions of proteins are flanked by globular domains. When located in close vicinity of the amyloid regions along the chain, the globular domains can ...
How does growth hormone releasing hexapeptide self-assemble in nanotubes?
(Royal Society of Chemistry, 2014-11)
Growth hormone releasing peptide, GHRP-6, a hexapeptide (His-(D-Trp)-Ala-Trp-(D-Phe)-Lys-NH2, MW = 872.44 Da) that belongs to a class of synthetic growth hormone secretagogues, can stimulate growth hormone secretion from ...
Kinetics and growth mechanism of the photoinduced synthesis of silver nanoparticles stabilized with lysozyme
(Elsevier Science, 2018-12)
A fast and single-step procedure is reported for the preparation of stable solutions of spherical-shaped silver nanoparticles (AgNPs) coated with lysozyme (LZ). The preparation of the AgNP@LZ nanocomposites was based on ...
Influencia de la forma de los agregados en la estabilidad y flujo de una mezcla asfáltica empleando el equipo Marshall
(Universidad Nacional de ColombiaManizales - Ingeniería y Arquitectura - Maestría en Ingeniería - Infraestructura y Sistemas de TransporteDepartamento de Ingeniería CivilFacultad de Ingeniería y ArquitecturaManizales, ColombiaUniversidad Nacional de Colombia - Sede Manizales, 2021)
En las mezclas asfálticas, lo ideal, es tener agregados con caras fracturadas para aumentar su resistencia y en general su capacidad, pero cuando no se puede recurrir a la realización de este proceso mecánico y debemos ...
New oligomeric surfactants with multiple-ring spacers: Synthesis and tensioactive properties
(Elsevier Science, 2005-12)
New anionic oligomeric (tetrameric) surfactants with different spacing architecture based on dioxane rings were synthesized, and their surface-active properties were studied. The synthesis of these compounds involves a ...
