Subsurface bonding of hydrogen in transition metals: dependence on surface orientation
(1994)
The calculation of the surface-induced enhancement of the binding energy of hydrogen impurities in transition metals, previously reported for close-packed surfaces, are extended to open surfaces in the fcc and bcc structures. ...
Continuous production of ethanol in bed packed bioreactors with immobilized yeast cells on lignocellulosic waste
(Universidad Nacional de Colombia Sede Medellín, 2012)
The continuous processes with immobilized cells are a good alternative for improving the efficiency and the performance of alcoholic fermentations. Raw materials derived from agroindustrial waste and their usage for ...
Modeling hydrogen production in a catalytic-inert packed bed reactor by rich combustion of heavy fuel oil
(Elsevier, 2018)
This work presents simulation results for the production of hydrogen by the rich combustion of heavy fuel oil in a dual zone packed bed reactor. The first zone provides catalytic thermal cracking of the fuel and is followed ...
Relaxation processes after instantaneous shear-rate reversal in a dense granular flow
(EPL Association, 2015)
A numerical model of granular material at different packing fractions and under
steady shear is submitted to a sudden shear reversal. We monitor consequences of the strong
density and shear rate spatio-temporal ...

Chitosan/chondroitin sulfate aerogels with high polymeric electroneutralization degree: formation and mechanical properties
(Walter de Gruyter GMBH, 2018-04)
The formation of ultralight, highly porous solid materials (porosity higher than 99 %) containing equivalent molar amounts of chitosan (CS) and chondroitin sulfate (ChS) is presented. First, we show protocols to produce ...
Efficacy of topical versus intravenous tranexamic acid in spinal deformity
(Springer, 2020)
Purpose To compare topical tranexamic acid versus intravenous tranexamic acid in reducing intra- and postoperative blood loss and transfusion rate in deformity patients. Materials and method We performed a retrospective ...
El tratamiento del plan AUGE (GES) de la anemia en diálisis crónica no ha sido eficaz y, probablemente, no se han aprovechado los recursos económicos destinados para elloResults of the explicit health guaranties program to correct anemia of end stage renal disease patients in dialysis
(Rev Med Chile, 2013)
Background: In July 2010 end stage renal disease anemia correction was incorporated
to the program of explicit health guaranties of the Ministry of Health. The
treatment plan included intravenous iron and erythropoietin. ...
Remoción de cromo hexavalente de soluciones acuosas usando cáscara de yuca (Manihot esculenta): experimentos en columna
