Rational approximations of the Arrhenius integral using Jacobi fractions and gaussian quadrature
(Springer, 2009-03-01)
The aim of this work is to find approaches for the Arrhenius integral by using the n-th convergent of the Jacobi fractions. The n-th convergent is a rational function whose numerator and denominator are polynomials which ...

Origin of non-arrhenius kinetics for the tetraatomic hydrogen exchange reactions of oh with HCl, HBr and HI : AB initio molecular dynamics
(2018-10-15)
As reações OH + HX ⟶ H2O + X ( X = Halogênio) tem um papel importante para a química da
atmosfera, uma vez que pertencem a uma classe de processos que produzem átomos de halogênios
que destroem a camada de ozônio. ...
Estudio cinético por análisis termogravimétrico en la degradación térmica en residuos de cáscara de naranja, generados en el cantón Caluma
(Escuela Superior Politécnica de Chimborazo, 2020-07-14)
In this research project, the kinetic study of the thermal degradation process of orange peel
residues were carried out, through an analysis of the variation in mass as a function of time. First,
the biomass was characterized ...
Reator batelada: construção de um modelo em escala laboratorial e obtenção dos parâmetros cinéticos e de Arrhenius em reações de fase líquida
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilEngenharia QuímicaUTFPR, 2019-11-27)
This work aims to design and build a batch reactor with controlled temperature and agitation and its mathematical validation based on obtaining the kinetic parameters of saponification reactions between ethyl acetate and ...
O uso da inteligência artificial e outras tecnologias na caracterização de fenômenos químicos e biológicos
(2022-12-29)
Modelos de aprendizagem estatística que utilizam métodos de Machine Learning
(ML), como o Generalized Simulated Annealing (GSA), vêm sendo utilizados há
décadas na química para diversas tarefas. Munido destas técnicas, ...
Desenvolvimento de software para dimensionamento de cabos isolados de parques eólicos, considerando critérios técnico e econômico
(BrasilUFRNMESTRADO PROFISSIONAL EM ENERGIA ELÉTRICA, 2017-07-28)
In Brazil there are 794,699 km of networks and only 12,348 km are of underground networks, that is, less than 2%, and the others are from overhead electricity distribution networks. However, it is estimated that about 30% ...
Effect of temperature on the optical properties of GaAsSbN/GaAs single quantum wells grown by molecular-beam epitaxy
(American Institute of Physics (AIP), 2003-04-15)
GaAsSbN/GaAs strained-layer single quantum wells grown on a GaAs substrate by molecular-beam epitaxy with different N concentrations were studied using the photoluminescence (PL) technique in the temperature range from 9 ...
