Determination of lower flammability limits of C-H-O compounds in air and study of initial temperature dependence
(2016-04-22)
The main objective of this study was to develop a method that can be used to estimate the lower flammability limits of C-H-O compounds at standard temperature and pressure. In addition, a study was carried out to develop ...
Infimal convolution and optimal time control problem II: limiting subdifferential
(Springer, 2017)
This paper is the continuation of our study of a general minimal time problem with a convex constant dynamics and a lower semicontinuous extended real-valued target function defined on a Banach space. We study several ...
Evaluation and standardization of the quality of semen: New lower reference limit Evaluación y estandarización de la calidad del espermiograma: nuevos límites inferiores de referencia
(2011)
Spermogram or semen analysis is one of the most used parameters in the evaluation of male fertility. WHO (2010) presented the 5th Manual for review and processing of human semen, a document that was discussed during the ...
Experimental determination of lower flammability limits of Synthesized Iso-Paraffins (SIP), jet fuel and mixtures at atmospheric and reduced pressures with air
(2021-05-01)
The creation of alternative fuels to reduce CO2 emissions in the aeronautical sector necessitates the determination of their safety properties, among which are their Flammability Limits. Synthesized Iso-Paraffins (SIP) are ...
Recent advances and new perspectives of ion-selective electrodes.

Aplicación de las Integrales al Comercio Exterior
(2016-07-01)
Determining the equation of the behavior of the variables that affect the market, it is possible to predict its behavior in an period determined between two limits, using the mathematical definite integrals
Estimation of lower flammability limits in high-pressure systems. Application to the direct synthesis of hydrogen peroxide using supercritical and near-critical CO2 and air as diluents
(Elsevier Science, 2011-02)
A method for the prediction of the LFL at high pressures, where data are scarce, based on the calculation of adiabatic flame temperatures for the mixtures H2 + O2 in CO2 and N2, between 1.0 and 300 bar and 288-348 K is ...
A detailed experimental and numerical assessment of the QAV – 1/anhydrous ethanol blends in their lower flammability limits
(2022-03-01)
Anhydrous ethanol is an attractive alternative to be used as a substitute or additive in petroleum-based fuels aiming to ensure environmental sustainability. In Brazil, ethanol has been used as an alternative fuel in both ...
