1. Synthesis and Molecular Modeling Study of Two Bromo-Dimethoxybenzaldehydes
This work describes the synthesis, molecular structure, and packaging of the compounds 6-bromo-2,3-dimethoxybenzaldehyde (6-BRB) and 5-bromo-2,3-dimethoxybenzaldehyde (5 BRB). Characterization in the solid-state was carried out by X-ray diffraction, and the analysis of the interactions was described by the Hirshfeld surface, which helps in understanding the

2. NO ESCAPE FROM CATEGORIZATION: AN INSIDER’S VIEW OF COMPOUNDS
Abstract There has been a surge of syntactic research on compounding, joining a large literature on the nature of roots and phase theory. In an attempt to probe into the syntactic domain for idiosyncratic interpretation and to account for categorial exocentricity, disappearance of subcategorization, and lexical integrity effects, some recent studies on compo

3. Recent Developments on the Elucidation of Colloidal Aspects of Asphaltenes and Their Relevance to Oilfield Problems
Asphaltenes constitute the heavy petroleum fraction responsible for deposition events that may lead to reduced oil production, therefore of great interest for flow assurance. These molecules self-assemble in solutions leading to formation of aggregates that eventually grow towards precipitation and blockages in reservoirs and pipelines. Based on the Yen-Mull

4. Experimental and Theoretical Study of LiMn2O4 Synthesized by the Solution Combustion Method Using Corn Starch as Fuel
Lithium manganese oxide, LiMn2O4, was synthesized in two temperature stages, where the first consisted by an ecofriendly solution combustion method at 300 °C. Finally, the as-burned powders were thermal treated at 500 and 700 °C. The structural and morphological changes were evaluated by the Rietveld method and density functional theory (DFT) calculations.

6. Partículas de Final de Sentença (PFS): uma análise cartográfica por fases sobre o sistema da língua Tenetehára
Resumo O objetivo deste artigo é analisar a distribuição das Partículas de Final de Sentença (PFS) em Tenetehára, as quais compõem um conjunto de itens funcionais que ocorrem em uma posição sintática rígida em posição sentencial final. A ordem das PFS nesta língua pode ser formalmente capturada se for considerada uma única estrutura de base, a

8. Ebaco-R: Refinement of organizational commitment bases scale
RESUMO O comprometimento organizacional, apesar de muito estudado, ainda permanece na agenda de pesquisa devido à falta de consenso nas questões conceituais e estruturais. Deste modo, esta pesquisa se propôs a refinar a Escala de Bases do Comprometimento Organizacional (EBACO) em busca de um instrumento com melhores propriedades psicométricas e maior ade

9. FACILE SYNTHESIS, CHARACTERIZATION AND DFT CALCULATIONS OF 2-ACETYL PYRIDINE DERIVATIVES
Deprotonation of 2-acetylpyridine was carried out in the presence of NaH as a phase transfer catalyst instead of NaOH to minimize side products formation. The products were then treated with two equivalents of alkyl/aryl halide to synthesize a variety of acetyl pyridine derivatives. The compounds were structurally characterized by 1H- and 13C-NMR spectroscop

10. Sigma Phase in Superduplex Stainless Steel: Formation, Kinetics and Microstructural Path
The superduplex stainless steels (SDSS) are widely used in chemical, oil and gas industries, to pipelines and storage material facilities. In welding process or working in temperature elevated, secondary phases may appear in the form of precipitates, as the sigma phase (σ) which is an intermetallic compound. This compound is harmful to the properties of ste

11. FACTORS INFLUENCIG SOFTWARE MIGRATION DECISION: CASE STUDIES OF ACERLORMITTAL TUBARÃO AND THE CITY GOVERNMENT OF SERRA, ESPIRITO SANTO
ABSTRACT The objective of this research is to identify the factors that influence the migration of free software to proprietary software, or vice-versa. The theoretical framework was developed in light of the Diffusion of Innovations Theory (DIT) proposed by Rogers (1976, 1995), and the Unified Theory of Acceptance and Use of Technology (UTAUT) proposed by V

12. On the Validation of a Numerical Model for the Analysis of Soil-Structure Interaction Problems
Abstract Modeling and simulation of mechanical response of structures, relies on the use of computational models. Therefore, verification and validation procedures are the primary means of assessing accuracy, confidence and credibility in modeling. This paper is concerned with the validation of a three dimensional numerical model based on the finite element
