Abstract As an alternative energy source for fossil energy, use of biomass pyrolysis to reduce pyrolusite is great significance conservation, emission reduction and environmental protection. Kinetics thermodynamics reducing using was studied thermogravimetric analysis analysis. Five non-isothermal methods, Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose, Distributed Activation Energy Model, Starink ...
Entre los coleópteros de importancia agrícola sobresale la familia Curculionidae, y entre éstos, el picudo Macrocopturus aguacatae Kissinger, está reconocido como una plaga que barrena las ramas del aguacate (Persea americana Mill.) El objetivo presente estudio fue evaluar preferencia alimentación en condiciones laboratorio. Para M. se probaron 23 variedades utilizando 2.0 a 2.5 cm diámetro 30 ...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
Abstract In the current work, a new variation of FeSiBPCu system with good glass forming ability and soft magnetic properties was developed investigated. The effect copper addition on FeSiBP base alloy studied in (Fe 0.77 Si 0.08 B 0.1 P 0.05 ) 100-x Cu x = 0, 0.25, 0.5, 0.75 1.0 at%. Microstructural evolution upon annealing process evaluated by XRD TEM, revealing formation α-Fe(Si), Fe 2 3 (B,...
in this study, a new efficient semi-analytical method is introduced to give approximate solutions of strongly nonlinear oscillators. the proposed method is based on combination of two different methods, the multi-step homotopy analysis method and spectral method, called the multi-step spectral homotopy analysis method (msham). in this method, firstly, we propose a new spectral homotopy analysis...
in this paper, we give an analytical approximate solution for an integro- differential equation which describes the charged particle motion for certain configurations of oscillating magnetic fields is considered. the homotopy analysis method (ham) is used for solving this equation. several examples are given to reconfirm the efficiency of these algorithms. the results of applying this procedure...
In this research, crystallization of Fe36Cr12Mo10 and α-Fe phases in devitrification of Fe51Cr18Mo7B16C4Nb4 amorphous alloy was studied using X-ray diffraction and transmission electron microscopy. For evaluation of crystallization kinetics, differential scanning calorimetric tests were carried out at different heating rates. Results showed that two-step crystallization led to the formati...
The isothermal and nonisothermal crystallization kinetics of monoglyceride (MAG) organogels were studied by pulsed nuclear magnetic resonance (pNMR) and differential scanning calorimetry (DSC), respectively. The Avrami equation was used to describe the isothermal crystallization kinetics and experimental data fitted the equation fairly well. Results showed that the crystal growth of MAG organog...
in this paper, nonlinear klein-gordon equation with quadratic term is solved by means of an analytic technique, namely the homotopy analysis method (ham).comparisons are made between the adomian decomposition method (adm), the exact solution and homotopy analysis method. the results reveal that the proposed method is very effective and simple.
