1. Austenitic Grain Size Prediction in Hot Forging of a 20MnCr5 Steel by Numerical Simulation Using the JMAK Model for Industrial Applications
Yield strength and toughness in steels are directly associated with hot forging processes, especially by controlling austenitic grain size and cooling conditions. The phenomenological JMAK model in macroscale has been applied in different material classes to predict grain size after hot forming. However, on an industrial application, there is still a lack of

2. QUALITATIVE AND PHENOMENOLOGICAL RESEARCH IN MENTAL HEALTH: MAPPING AS A PROPOSED DESCRIPTIVE METHOD
Resumo O modelo de Atenção em Saúde Mental vem sendo discutido no Brasil há décadas. Nos últimos anos, passou da atenção hospitalar para Atenção Psicossocial territorializada, modelos que convivem lado a lado, demandando conhecer como se arranjam os processos assistenciais. Este trabalho apresenta o método fenomenológico como potencial para esta

3. Kinetics study and modelling of sorghum grain hydration
RESUMO Neste estudo, grãos de sorgo foram hidratados para avaliar os efeitos do tempo e temperatura na umidade e modelar o processo com diferentes equações matemáticas. Para esse fim, as cultivares de sorgo BRS 310 e BRS 655 foram submetidas à hidratação nas temperaturas de 30 ºC, 40 ºC, 50 ºC e 60 ºC, por um período de 12 horas. O processo de hi

4. Controlling sintering and grain growth of nanoceramics
Resumo Sinterização e crescimento de grão são processos fundamentais que afetam a evolução microestrutural das cerâmicas. Os modelos fenomenológicos que descrevem esses processos, conforme encontrados nos livros didáticos, são simplificações do conjunto altamente dinâmico de parâmetros do sistema, o que leva à previsibilidade limitada e à nec

5. Lessons and perspectives for applications of stochastic models in biological and cancer research
The effects of randomness, an unavoidable feature of intracellular environments, are observed at higher hierarchical levels of living matter organization, such as cells, tissues, and organisms. Additionally, the many compounds interacting as a well-orchestrated network of reactions increase the difficulties of assessing these systems using only experiments.

6. Tecendo teias complexas em curso online para futuros professores de inglês
This study aims at describing and interpreting two phenomena of human experience: developing-operating an online course based on the Complexity Theory and reflection on the teaching and learning of the English Language. These phenomena were investigated, from a course entitled Virtual Classroom: English teachers are (in)-formed on the teaching profession, br

7. Experimental investigation on the yield behavior of Nomex honeycombs under combined shear-compression
This paper presents an experimental investigation on the yield behavior of Nomex honeycombs under combined shearcompression with regard to out-of-plane direction. Four different types of specimens were designed in order to investigate the influence of in-plane orientation angle on the yield behavior of honeycombs under combined loads. Two different failure m

8. Nova metodologia para análise de identificabilidade e estimação de parâmetros de modelos fenomenológicos
Model identification is the activity of constructing representative mathematical models of real systems. Several techniques are available for its completion, which depend on the level of information available about the studied system. In this work techniques for gray-box identification, which use both phenomenological models and experimental data, were studi

9. Análise de genes envolvidos no modelo de epilepsia de lobo temporal induzido pela pilocarpina / Analysis of genes involved in the temporal lobe epilepsy induced by pilocarpine
The epilepsies affect approximately 1% of the population worldwide. Temporal lobe epilepsy (TLE) is the most frequent and commonly resistant to clinical treatment. Animal models have been widely used in order to study the mechanisms underlying TLE, especially those induced by chemical agents or electrical stimulation. It is believed that these models present

10. Recent trends in the modeling of cellulose hydrolysis
This work reviews recent trends in the modeling of cellulose hydrolysis, within the perspective of application of kinetic models in a bioreactor engineering framework, including scale-up, design and process optimization. From this point of view, despite the phenomenological insight that mechanistic models can provide, the expectation that more detailed appro

11. Synthesis of a Magneto-Rheological vehicle suspension system built on the variable structure control approach
The synthesis of a magneto-rheological vehicle suspension system built on the variable structure control approach is considered in the present work. The suspension is synthesized in order to improve the ride comfort obtained by a standard passive suspension. Although a nominal half-vehicle model with rigid body is considered in the synthesis of the suspensio

12. Parametric analysis of a phenomenological model for vortex-induced motions of monocolumn platforms
Phenomenological models are an important branch in VIV (Vortex-Induced Vibrations) and in VIM (Vortex-Induced Motions) studies to complement the results achieved via CFD (Computational Fluid Dynamics), as the latter tool is not presently a suitable tool for intense use in engineering analysis, due to high computer power requirements. A phenomenological model
