abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
The thermal behavior of green clay samples from the Arumetsa and Füzérradvány deposits (Hungary) influence two new types Estonian oil shale (OS) ashes cement bypass dust (clinker dust) additives on it were objectives this study. Thermal thermo-dilatometric analysis methods applied using a Setaram Setsys 1750 thermoanalyzer coupled with Pfeiffer Omnistar spectrometer CS Evolution dilatometer. ki...
The global steel industry uses fossil fuels to produce millions of tonnes iron ore sinter each year. Sintering is an energy-intensive process that fuses and flux material balances a high mechanical strength at sufficient particle size ensure macroporous burden in the blast furnace enable rapid gas flow. As significant CO2 greenhouse emissions are emitted, defossilisation these vital net-zero ca...
Graptolite–argillites (black shales) are studied as potential source of different metals. In the processing technologies graptolite–argillites, a preceding thermal treatment is often applied. this study, behavior Estonian graptolite–argillite (GA) samples from Toolse, Sillamäe and Pakri areas were using Setaram Labsys Evo 1600 thermoanalyzer coupled with Pfeiffer OmniStar Mass Spectrometer. The...
An efficient design of in situ combustion depends on accurate kinetic modeling of the crude oil oxidation. The kinetic triplet of the oxidation reactions of a heavy oil sample was investigated. Once the kinetic triplet is known, the kinetic equation would be deconvolved. The crude oil sample was obtained from Kuh-E-Mond reservoir, located in the southwest of Iran. The samples were analyzed usin...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
Surface oxygen of oxide catalyst has low coordination number; they are negatively charged. can act active site for decomposition energetic nitramines (i.e. HMX). Additionally hydrous surface release OH radicals. Colloidal particles fulfil these requirements. Furthermore induce thermite reaction with aluminium particles. This study reports on the facile fabrication colloidal ferric 5 nm average ...
Kinetic Modeling of Ring-Opening Polymerization of Benzoxazines Using MIL-53-Al as a Potent Catalyst
In this study, we report the successful synthesis of a novel Al-based MOF/polybenzoxazine nanocomposite by facile and green approach via thermally induced ring-opening polymerization (ROP). Structural thermal characterization synthesized was accomplished using FTIR, XRD, BET TGA, DSC techniques, respectively. The Al-MOF showed catalytic activity in ROP good stability compared to non-catalyzed s...
Out of autoclave (OoA) processing techniques, such as liquid composite moulding techniques (LCM) and, particularly, the vacuum-assisted resin infusion (VARI) technique, are being used, with increasing success, in replacement prepreg/autoclave technologies to produce structural aircraft/aerospace polymer parts, due its better cost effectiveness and competitiveness. This work aims embed Fibre Bra...
