Optimal transfer trajectories to the haumea system
(2014-01-01)
This paper provides a preliminary study of a mission to the dwarf planet Haumea, focusing on the travel between the Earth and this Kuiper Belt Object (KBO). We generate a set of transfer trajectories from the Earth to ...
Evaluation of heat transfer parameters in packed beds with cocurrent downflow of liquid and gas
(Pergamon-Elsevier Science Ltd, 2001-11)
The results of an experimental investigation on heat transfer from a packed bed with cocurrent gas-liquid downflow to the wall are presented and analyzed in this contribution. The measurements cover the range of operating ...
Implementación del sistema de contratación internacional BOT (Build, Operate and Transfer) como herremienta de descentralización y desarrollo territorial para los gobiernos regionales
(Universidad de Valparaíso, 2012)
El sistema de contratación BOT (Build, Operate, and Transfer) es un sistema de concesiones utilizado para generar infraestructura nacional mediante la inversión de capitales privados. Estos invierten en un área específica, ...
Ergodic theory of rational fractions on ultrametric bodies
(WILEY, 2010)
We make the first steps towards an understanding of the ergodic properties of a rational map defined over a complete algebraically closed non-archimedean field. For such a rational map R, we construct a natural invariant ...
Influence of operational parameters on the fluid-side mass transfer resistance observed in a packed bed bioreactor
(Springer Verlag Berlín, 2015-12)
The influence of mass transfer on productivity as well as the performance of packed bed bioreactor was determined by varying a number of parameters; flow rate, glucose concentration and polymers (chitosan). Saccharomyces ...
Material Transfer Operations in Batch Scheduling: A Critical Modeling Issue
(American Chemical Society, 2008-12)
An effective short-term scheduling formulation must simultaneously deal with several problem difficulties commonly arising in batch processes operations. One of the key features to be considered is the representation of ...
Mass Transfer Performance of Ethanol Removal by CO2 Stripping in Different Pneumatic Bioreactors
(2020-04-01)
The hydrodynamics and mass transfer characteristics of ethanol stripping with CO2 were evaluated for a 2.0-L pneumatic bioreactor operated in bubble column (BC), concentric-tube airlift (CTA), and split-cylinder airlift ...
