1. Finite element computational development for thermo-mechanical analysis of plane steel structures exposed to fire
Abstract This article presents a numerical formulation based on finite element procedures for application in nonlinear thermo-mechanical analyses of steel planar structures under fire condition. The mechanical properties of structural elements degrade when subjected to high temperatures, resulting in significant reductions in strength and stiffness. Under th

2. Medicinal Electrochemistry of Halogenated and Nitrated Pterocarpanquinones
Electrochemical methods are considered useful tools for simulations of biological redox reactions. The activities of quinones depend on their bioreduction. Biologically active pterocarpanquinones LQB-149 (nitroderivative), 150 and 151 (bromo and chloroderivatives, respectively) were electrochemically investigated by cyclic voltammetry, differential pulse vol

3. POESIA CIBORGUE E PÓS-HUMANIZAÇÃO DA LINGUAGEM: DA EXTERNALIZAÇÃO TECNOLÓGICA À RECUPERAÇÃO DA AUTONOMIA HUMANA
RESUMO Se o pós-humanismo surge hoje como expressão de formas diversas de questionar a excepcionalidade do humano, e se, por outro lado, a linguagem verbal é considerada uma expressão dessa mesma excepcionalidade do humano, a pós-humanização da linguagem revela uma tensão fundamental: entendida enquanto externalização e automação da linguagem ver

4. Aperfeiçoamento de modelo de estimativa da eficiência de remoção de turbidez da água em floculadores tubulares helicoidais
RESUMO Estudos científicos têm demonstrado que os floculadores tubulares helicoidais (FTHs) têm alta eficiência na formação de flocos e baixo tempo de retenção hidráulica, quando comparados aos floculadores comumente usados em tratamento de água e esgoto. No entanto, sua aplicação prática é limitada, pois ainda existe demanda significativa por

5. SENSITIVITY ANALYSIS FOR MODEL COMPARISON AND SELECTION IN TISSUE ENGINEERING
ABSTRACT Computational modeling has been proven to be very useful in tissue engineering over the past years. Because the model is a simplification of the experimental system, the processes accounted for in the model should be analyzed carefully. However, new and complex models are usually proposed without a clear comparison with the basic ones. In this study

9. Evaluating the hot metal dephosphorization efficiency of different synthetic slags using phosphorus partition ratio, phosphate capacity and computational thermodynamics
Abstract Phosphate capability (CP) and phosphorus partition ratio (LP) are usually used to evaluate the thermodynamic efficiency of dephosphorization slags with different compositions in hot metal pretreatment. However, these parameters are only useful in equilibrium conditions, and they are not accurate when they are used to evaluate slag efficiency in indu

10. Thermal analysis of steel-concrete composite cross sections via CS-ASA/FA
Abstract When exposed to high temperatures, such as in a fire situation, the physical and resistance characteristics of the materials employed in the structure deteriorate as the temperature increases. This fact promotes a considerable loss in the bearing capacity and stiffness of the structural system. The verification of a structure exposed to fire depends

11. Numerical analysis of the liquid ejection due to the gaseous jet impact through computational fluid dynamics
Abstract Metal droplets generated by an impinging jet, play an important role in metal refining processes, mainly in oxygen steelmaking, where the droplets are ejected into the slag phase. Since the available interfacial area of droplets is very high in this process, the generated droplets enhance the rates of heat transfer and chemical reactions. Therefore,

12. Evaluation of Filler Effects on the Dynamic Mechanical Behavior of HTPB-Elastomer Used as Binder in Exemplary Composite Formulations
ABSTRACT: This study aims to evaluate the dynamic mechanical properties of a binder, used in composite propellants, with increasing amount of different solid fillers. Dynamic Mechanical Analysis (DMA) is performed to determine the region of glass-rubber transition temperature (Tg). Further parameters were obtained from the description of the loss factor curv
