Non-instrumented nucleic acid amplification tests (NINAAT) are a novel paradigm in portable molecular diagnostics. They offer the high detection accuracy characteristic of nucleic acid amplification tests (NAAT) in a self-contained device, without the need for any external instrumentation. These Point-of-Care tests typically employ a Lab-on-a-Chip for liquid handling functionality, and perform ...

Thermal degradation of lignin in nitrogen atmosphere is evaluated by linear heating and isothermal tests. While suggests that thermal decomposition the 200–400 °C range mainly consists a single step, careful analysis tests points to different fractions having stabilities. This an important point for practical predictions, since kinetics obtained as if degradations at temperatures were same woul...

Development of effective heat treatments is crucial to achieve food products safety, and predictive microbiology is an excellent tool to design adequate processing conditions. This work focuses on the application of a modified Gompertz model to describe the inactivation behaviour under time-varying temperature conditions at the surface of a food product. Kinetic studies were carried out assumin...

In the present studies, silicon based low-density ablative material has been studied for its performance to protect flight hardware from temperature raises due aerodynamic forces a longer duration. The oxyacetylene flame test estimates properties at 100–120 W/m2 heat flux. time duration is taken 200 s. shows low mass and linear ablation rate with high effectiveness. degradation kinetics of abla...

Understanding the interaction between a fluid and a solid phase is of fundamental importance to the design of an adsorption process. Because the heat effects associated with adsorption are comparatively large, the assumption of isothermal behavior is a valid approximation only when uptake rates are relatively slow. In this article, we propose to determine when it is needed to choose the isother...

A special plasticity-based constitutive model with an up–down–up flow rule used within a finite element framework has previously been shown to simulate the inhomogeneous nature and the thermo-mechanical coupling of stress-induced transformation seen in a NiTi shape memory alloy. This paper continues this numerical study by investigating the trends of localized nucleation and propagation phenome...

This paper has been utilizing the simultaneous ThermoGravimetric analysis and Differential Scanning Calorimetry (TG–DSC) to investigate the thermal decomposition of magnesium-sodium nitrate pyrotechnic composition based HTPB resin. The thermal behaviors of different samples with various fuel-oxidizer ratio contents were determined. Decomposition kinetic was investigated by evaluating the in...
