After craniotomy extracellular glucose and lactate were good "biomarkers" of cerebral damage in TBI patients. We consider that high extracellular lactate and low glucose is an indicator of severe neurological damage and poor outcome, because of impaired brain metabolism.
This article presents the use of a graphical user interface in MATLAB® language called CombustionUA v1.0, for the thermodynamic study of the behavior of excess air, relative humidity, and air temperature in complete and incomplete combustion processes. The tool developed allows comparing the performance of different fuels under different operating conditions, since stoichiometry of different combustion reactions, calculation of thermochemical properties of fuels and energy balances have been programmed, so that the user can develop parametric case studies. The work shows the methodology and results of the application of three case studies, which were analyzed using the new educational software. In addition, the fundamental equations used in the development of the software algorithm are presented, as well as the maximum error rates obtained when validating the software in a group of mechanical engineering students at the Universidad del Atlántico. With the help of the software, it was concluded that the fuels with the best air fuel ratio and the highest heat transfer were determined, as well as the differences between the dew point temperatures of a complete combustion and an incomplete combustion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
