For Henry Kissinger, a stable international order is not only based on balance of power, but also identities, “visions itself ”. How do our observational theories relations come to understand this practical maxim? This article shows that rationalist theories, methodological underpinnings fall short satisfactorily addressing the issue, while constructivism’s and post-structuralism’s social ontol...

This study aims to investigate the thermal properties of phase transformation that may occur with effect temperature in Cu-14.70wt.%Al-4.72wt.%Ni shape memory alloy. The sample was annealed at 1203 K for 30 min an argon atmosphere and then cooled rapidly salt-ice water. By using Differential Scanning Calorimetry (DSC), martensitic parameters were found. activation energy required these transfor...

In here, the nonisothermal decomposition kinetics of co-polymers based phenothiazine was present-ed. For this, firstly, 3, 7-di-2-thienyl-10H-phenothiazine (TF) prepared via an optimized Suzu-ki–Miyaura cross-coupling reaction. After monomer characterization, copolymerization re-actions with EDOT and thiophene were performed by electrochemical technique. The molecular masses found gel permeatio...

The paper presents the combustion profile of selected fuels as a result thermogravimetric analysis. main purpose this study was to investigate mixture different types fuel and influence use additive on process profile. As additive, halloysite used profiles. It confirmed that parameters such ignition temperature, burnout maximum peak temperature correlated accordingly with combustibility indices...

A characteristic of granulated LTA and SOD zeolites is given. It was determined that zeolite particles have a cube shape with size ~2 μm; an irregular 0.5–1 μm. The dimension the coherent scattering region calculated to be 760 nm for 453 SOD. specific surface area 115 m2·g–1 141 m2·g–1. Static tests showed maximum quantity absorbed water vapor ~30 wt.%, ~20 wt.%. found provide adsorption from g...

The co-precipitation technique was used to successfully produce nanometer cobalt ferrite (CoF). Utilizing the solvent-antisolvent approach, reduction in size of sensitive HEM 3-nitro-2,4-dihydro-3H-1,2,4-triazol-5-one (NTO) effectively achieved. Using simultaneous thermal analysis, effect 5% by mass CoF on thermolysis NTO and nanosize (r-NTO) investigated. kinetic parameter r-NTO presence addit...

The analysis and review of the thermal decomposition properties required for fire spread simulation cables composed multiple materials were performed. Thus, a typical two-step pyrolysis reaction was identified independent cable type. It is expected that Kissinger flynn–wall–ozawa (FWO) methods, which are calculated using various heating rates, more accurately predict than input method uses valu...

Esta investigación caracteriza la cinética de pirólisis del esquisto bituminoso con potencial en petróleo no convencional Cuenca Lancones (Perú). Se aplica termogravimetría un medio inerte (nitrógeno) usando tres velocidades calentamiento (β=5, 10, 20 °C/min) amplio intervalo temperaturas (25 a 800 °C). El triplete cinético se determina el método isoconversional Kissinger-Akahira-Su...
