The Relationship between Mechanical Properties and Gradual Deterioration of Microstructures of Rock Mass Subject to Freeze-thaw Cycles
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2018-01-01)
Under freeze-thaw cycles, the relationship between rock microstructure deterioration and its macroscopic mechanical characteristics has drawn extensive attention from engineers. With the objective to incorporate freeze-thaw ...
Mechanical Performance of Concrete with Waste from Oil Industry
(ACI American Concrete InstituteUnited State., 2016)
In this paper, the mechanical properties of concrete with an added residue of the petrochemical industry (at levels of 10, 20, 30%), called catalytic cracking catalyst residue (FCC), are evaluated. The mechanical properties ...
Effect of plasticizers on the physico-mechanical properties of pullulan based pharmaceutical oral films
(Elsevier B.V., 2017)
© 2016 Elsevier B.V.The effect of different plasticizers (glycerol, vitamin E TPGS and triacetin) and their concentrations on the physico-mechanical properties of pullulan based oral films was studied. A full factorial ...
Development and characterization of polyvinyl alcohol stabilized polylactic acid/ZnO nanocomposites
(IOP Publishing Ltd., 2017)
The present work is focused on the development of polylactic acid/ZnO (PLA/ZnO) polymer nanocomposite through a melt blending route. Previously, the ZnO nanoparticles were coated with polyvinyl alcohol (PVA) via a solvothermal ...

On somemixedvariationalprinciplesinmagneto-elastostatics
(Elsevier, 2013)
Some mixed variational formulations are presented for the problem of a deforming and magneto-active body completely surrounded by free space. The possibility of large elastic deformations is considered, in particular due ...
Evaluación de la metodología de ensayo acelerado de barras de mortero ASTM C 1260 para detectar agregados potencialmente reactivos y las medidas de mitigación de la reacción álcali-sílice ASTM C 1567
(Escuela Colombiana de Ingeniería Julio Garavito, 2018)
The alkali-silica reaction is defined as a phenomenon produced by the alkalis (sodium or potassium) of the cement, which react with the silica present in certain aggregates, forming a gel that under conditions of humidity ...
Influence of frozen and canned storage on the parameters of color, texture and thermal stability of golden kinglip (Genypterus blacodes) Influencia del congelado y enlatado sobre las propiedades del color, textura y estabilidad térmica de congrio dorado (
(2007)
Changes in color, texture and thermal stability were determined for the golden kinglip species (Genypterus blacodes) frozen and stored at -18 °C and -30 °C for 6 months. In golden kinglip canned fish, these parameters were ...
