1. Comparison of the autonomic nervous system dysfunction between different chronic spine disorders: neck pain versus low back pain
SUMMARY OBJECTIVE: This study aims to compare heart rate variability (HRV) between patients with chronic neck pain and patients with chronic low back pain and to correlate the chronic pain variables with heart rate variability indices. METHODS: This is a cross-sectional study. We divided the sample into two groups: neck pain (n=30) and low back pain (n=30)

2. Finite strip method computer application for buckling analysis of thin-walled structures with arbitrary cross-sections
Abstract The Direct Strength Method (DSM) is a well-known formulation presented in the Brazilian standard ABNT NBR 14762:2010, that estimates the strength capacity of cold-formed steel (CFS) members. However, this formulation requires the elastic critical buckling loads as point of departure, regarding local (L), distortional (D) and global (G) modes, which

3. Omni-Directional Wideband Antenna Array with Solar Cells
Abstract Distributed sensor networks are becoming more and more widespread due to their substantial benefits to our daily lives. These sensors, in most cases, are distributed in nature and even may require mobility. This, in turn, implies omnidirectional collector units to collect the data from various sensors at arbitrary directions. This work summarizes th

5. Phenylalanine Hydroxylase (PAH) Genotyping in PKU Argentine Patients
Abstract Phenylketonuria (PKU, OMIM 261600) is predominantly caused by mutations in the PAH gene. One hundred and three Argentine PKU patients were studied by Sanger sequencing; 101 were completely characterized (90.3% were compound heterozygotes). Fifty-four different pathogenic variants were identified. Mutations were distributed all along the PAH gene but

6. “UM JOGO DE PARTIDOS”: EDUCAÇÃO PÚBLICA E POLÍTICA NO MARANHÃO IMPERIAL
Resumo Este artigo discute as relações entre educação pública e disputas políticas na província do Maranhão. Partimos de um evento ocorrido em julho de 1838: a demissão de um professor substituto motivada, segundo relato da imprensa de oposição ao governo, por perseguição política. A denúncia tratou o caso como mais uma arbitrariedade do entã

7. Políticas públicas para o Ensino Superior a Distância: um exame do papel da Universidade Aberta do Brasil
Resumo Examina-se neste artigo, o papel da Universidade Aberta do Brasil (UAB), como uma política pública para o ensino superior a distância, na democratização do acesso ao ensino superior e na redução de desigualdades sociais no país. Para tanto, foi realizada uma revisão de literatura e coleta de dados secundários. Como a UAB constitui parte do s

8. Analysis of macrophage subtypes and annexin A1 expression in lesions of patients with cutaneous leishmaniasis
Abstract INTRODUCTION: Cutaneous leishmaniasis is caused by protozoa of the genus Leishmania and transmission occurs through the bite of sandflies. It is an infectious disease, which affects skin and mucosa. The aim was to quantify the macrophages M1 and M2 and the annexin A1 expression in the skin lesions of patients with cutaneous leishmaniasis. METHODS

9. ARISTOTLE’S ARGUMENT FROM UNIVERSAL MATHEMATICS AGAINST THE EXISTENCE OF PLATONIC FORMS
Abstract In Metaphysics M.2, 1077a9-14, Aristotle appears to argue against the existence of Platonic Forms on the basis of there being certain universal mathematical proofs which are about things that are ‘beyond’ the ordinary objects of mathematics and that cannot be identified with any of these. It is a very effective argument against Platonism, becaus

10. Two methods for solving electrostatic problems with azimuthal symmetry
Abstract The study of electrostatic phenomena is the gateway to the physics described by Classical Electrodynamics. In this paper, we discuss in detail two methods based on the Uniqueness Theorem for solving electrostatic problems with azimuthal symmetry. The first one is the electrostatic potential extension from the axis of symmetry to an arbitrary point.

11. New nonlinear solution of nearly incompressible hyperelastic FGM cylindrical shells with arbitrary variable thickness and non-uniform pressure based on perturbation theory
Abstract In this paper, nonlinear analysis of thick cylindrical shells with arbitrary variable thickness made of hyperelastic FGM with radially variation of material properties in nearly incompressible state under non-uniform pressure loading is presented. Thickness and pressure of the shell vary in axial direction by linear and/or nonlinear functions. The g

12. Free Vibration of flexible soft-core sandwiches according to layerwise theories differently accounting for the transverse normal deformability
Abstract This study aims to generalize a previously developed accurate and inexpensive 3-D zig-zag theory up to an arbitrary representation form and to determine which simplifications are yet accurate in determining transverse shear and normal stress/deformation effects on vibrations of soft-core sandwiches with not moving middle/neutral plane (pumping).
