1. Mathematical Modeling of the Film Influence on the Salting Time of Mozzarella Cheese in a Static and Dynamic System: Application of Artificial Neural Networks of the Multilayer Perceptron Type
The NaCl and KCl diffusion in the film formed on the cheese surface during salting was simulated by the finite element method. The time and salts concentration values on the cheese surface were determined, tabulated, and presented to the multilayer perceptron neural network (MLP) for the regression modeling. The samples were divided into 70, 15 and 15% for t

2. Clinical Significance of HSCARG for Atherosclerotic Coronary Heart Disease and Reduced ROS-Oxidative Stress in in Vivo and in Vitro Models via p47phox by NF-κB Activity
ABSTRACT Introduction: Coronary heart disease (CHD) is a dynamic process in which there are interactions between endothelial dysfunction, oxidative stress, and inflammatory responses. The aim of the present study was to investigate the function and mechanism of HSCARG in the treatment of CHD. Methods: Male apolipoprotein E/low-density lipoprotein receptor-

3. THE INFLUENCE OF THE FILM FORMED ON THE PRATO CHEESE SURFACE DURING THE NACL AND KCL SALTING PROCESS: APPLICATION OF THE FINITE ELEMENT METHOD AND NEURAL NETWORKS OF THE SELF-ORGANIZING MAP (SOM) AND MULTILAYER PERCEPTRON (MLP) TYPES
Sodium chloride is used in the cheese salting process as it promotes sensory changes and food preservation. However, in excess can cause hypertension problems, and for this reason, it has been partially replaced by potassium chloride. In the present work, Prato cheese was subjected to joint diffusion of NaCl and KCl by immersion in static and stirred brine.

4. Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization
Abstract Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore modeling to honor the structural aspects that control the mineralization. The grade domains are de

6. Liquid-phase RTD studies in a flotation column: an analysis between tanks-in-series and axial dispersion models
Abstract The objective of the present study is to evaluate the fluid dynamics of a flotation column (2" in diameter and 6 m in height) based on gas hold-up measurements and, in particular, by applying the liquid-phase RTD (residence time distribution) technique. Additionally, a comparative study is performed between different methodologies used to determine

8. SYNTHESIS, CHARACTERIZATION, ADSORPTION AND THERMODYNAMIC STUDIES OF PURE AND BINARY CO2-N2 MIXTURES ON OXYGEN ENRICHED NANOSTRUCTURED CARBON ADSORBENTS
Abstract Oxygen enriched porous carbons have been synthesized by a nanocasting technique using mesoporous zeolite as template and epoxy resin as precursor. Characterization results show the effect of the nanocasting technique on the development of heterogeneous surface, high basicity, and high surface area of 686.37 m2g-1, beneficial for CO2 adsorption. Pure

9. Investor sentiment and earnings management in Brazil
RESUMO A pesquisa analisa se existe associação temporal entre o sentimento do investidor e o gerenciamento de resultados no Brasil. Vários estudos investigaram os determinantes do gerenciamento de resultados, fatores externos ou internos das empresas e normativos, mas poucos consideraram fatores pessoais, tal como o sentimento dos investidores no Brasil.

12. Applicability of Performance Prism in SMEs: a multiple case study
Resumo Na literatura sobre os modelos de avaliação de desempenho organizacional, são um tanto raras as pesquisa sobre o Performance Prism (PP), especialmente quanto ao seu uso como ferramenta de gestão e sua validade como instrumento direcionador da estratégia. Também são escassos os estudos sobre a aplicabilidade das pesquisas relacionadas à implem
