13. An overview of the appendicular skeletal anatomy of South American titanosaurian sauropods, with definition of a newly recognized clade
Abstract: In the last two decades, the number of phylogenetically informative anatomical characters recognized in the appendicular skeleton of titanosaurian sauropod dinosaurs has increased dramatically with the discovery of new and comparatively complete specimens. Here we provide an overview of the appendicular skeletal morphology of South American titanos

14. Sensitivity of hydrological connectivity in a semiarid basin with a high-density reservoir network
Resumo Os reservatórios de água, em geral, têm sido considerados a principal causa de redução da conectividade hidrológica a jusante nos canais. Portanto, este estudo tem como objetivo analisar a sensibilidade da conectividade hidrológica na bacia hidrográfica do reservatório de Orós, utilizando o modelo ResNet, desenvolvido para simular os process

15. Network Characteristics Analysis of Air Traffic Management Technical Support System Based on Multi-source Weighting
ABSTRACT In order to make reasonable suggestions for the expansion of the Air Traffic Management Technical Support System (ATMTSS), it is necessary to conduct a comprehensive analysis of the ATMTSS network. This paper constructs a multi-source weighted ATMTSS network which considers the working characteristics and geographical locations of the facilities. Th

17. Grandezas físicas multidimensionais
Resumo No presente trabalho apresentamos a continuação do recente artigo “Grandezas Físicas Unidimensionais”, publicado na Revista Brasileira de Ensino de Física. A construção operacional de uma grandeza passa pela definição de seu domínio, separação do domínio em classes e, por fim, associação injetiva de um espaço de valores às classes.

18. The complete chloroplast genome sequences of three Spondias species reveal close relationship among the species
Abstract This study reports the complete chloroplast sequences of three Spondias species. The genome sequences were obtained for Spondias tuberosa, Spondias bahienses, and Spondias mombin using the Illumina sequencing technology by a combination of de novo methods and a reference-guided assembly using Sapindus mukorossi as reference. The genomes of S. tubero

19. Self-organizing maps in the study of genetic diversity among irrigated rice genotypes
ABSTRACT. This study presents self-organizing maps (SOM) as an alternative method to evaluate genetic diversity in plant breeding programs. Twenty-five genotypes were evaluated in two environments for 11 phenotypic traits. The genotypes were clustered according to the SOM technique, with variable topology and numbers of neurons. In addition to the SOM analys

20. Two-scale topology optimization of macrostructure and porous microstructure composed of multiphase materials with distinct Poisson’s ratios
Abstract Negative Poisson’s ratio (NPR) material attracts a lot of attentions for its unique mechanical properties. However, achieving NPR is at the expense of reducing Young’s modulus. It has been observed that the composite stiffness can be enhanced when blending positive Poisson’s ratio (PPR) material into NPR material. Based on the respective inter

21. Artificial neural networks modeling of kinetic curves of celeriac (Apium graveolens L.) in vacuum drying
Abstract The objective of this study was to predict celeriac drying curves using artificial neural networks (ANNs). The experimental data for vacuum drying kinetics of celeriac slices reported by other researcher in the previously published article was used. The air temperature, chamber pressure and time values were used as ANN inputs. To predict the moistu

22. TOPOLOGIA DOS ORBITAIS MOLECULARES DE POLIENOS PARA DEDUZIR ENERGIAS RELATIVAS E AVALIAR AROMATICIDADE
A didactic alternative approach is proposed for deducing the molecular orbital topology of acyclic and cyclic polyenes and then evaluating their bonding, antibonding, and nonbonding character. The relative energies of molecular orbitals of neutral molecules and ions were described, in addition to the orbital degeneracy to cyclic conjugated polyenes, and the

23. TOPOLOGIA UNIFICADA DOS ORBITAIS MOLECULARES DE FRONTEIRA PARA EXPLICAR REAÇÕES PERICÍCLICAS
In this work is proposed a didactic alternative vision to teach pericyclic reactions. To this end, they were classified according to the connectivity of reactants systems, as connected atom reactions (CAR) and the other possibility, as not connected atom reactions (NOCAR). Electrocyclic reactions and sigmatropic rearrangements are examples of CAR categorizat

24. A Quantitative Comparison Between Size, Shape, Topology and Simultaneous Optimization for Truss Structures
Abstract There are typically three broad categories of structural optimization namely size, shape and topology. Over the past few decades various researchers have focused on developing techniques for optimizing structures by considering either one or a combination of these aspects. In this paper the efficiency of these techniques are investigated in an effor
