Kinetic parameters for thermal decomposition of hydrazine
The propulsion of most of the operating satellites comprises monopropellant (hydrazine - N2H4) or bipropellant (monometilydrazine - MMH and nitrogen tetroxide) chemical systems. When some sample of the propellant tested ...
Kinetic models for nitrogen inhibition in anammox process on deammonification system.
(In: SIMPÓSIO INTERNACIONAL SOBRE GERENCIAMENTO DE RESÍDUOS AGROPECUÁRIOS E AGROINDUSTRIAIS, 4., 2015, Rio de Janeiro, RJ. Anais... Brasília: Embrapa, 2015., 2015)
Stable and metastable ferroelectric polarization analyzed by the ramp voltage technique
The study of the stable and the metastable ferroelectric polarization of poly(vinylidene fluoride), PVDF, was performed using two successive equal sign ramp voltages, mediated by a short-circuit period. Rates from 10 V/s ...
Mathematical analysis and simulations involving chemotherapy and surgery on large human tumours under a suitable cell-kill functional response
Dosage and frequency of treatment schedules are important for successful chemotherapy. However, in this work we argue that cell-kill response and tumoral growth should not be seen as separate and therefore are essential ...
Effects of pyrogenic carbon feedstock and pyrolysis temperature on the oxidation kinetic and benzene polycarboxilic acids formation.
(In: MEETING OF THE INTERNATIONAL HUMIC SUBSTANCES SOCIETY, 17., 2014, Ioannina. Natural organic matter: structure-dynamics innovative applications: book of abstracts. Ioannina: University of Ioannina, 2014. p. 192-193., 2014)
Kinetics of zinc status in patients with IDDM

Kinetics of martensitic phase decomposition in the Cu-10wt.%Al alloy with Ag additions
The study of the kinetics of martensitic phase decomposition in the Cu-10wt.%Al alloy with Ag additions showed that the presence of Ag retarded the eutectoid decomposition reaction and enhanced martensite stabilization. ...
The submicroscopic level of chemistry: analyzing learning objects to help the teacher in the process of teaching and learning
many knowledge covered in the discipline of chemistry, especially the submicroscopic level, require teachers to use didactic resources to assist them during the process of teaching and learning. In view of this concern, ...
