1. 2D magnetometric modeling of a basic-intermediate intrusion geometry: geophysical and geological approaches applied to the Limeira intrusion, Paraná Magmatic Province (SP, Brazil)
ABSTRACT: The Limeira Intrusion is an occurrence related to the Mesozoic continental flood basalts of Paraná Magmatic Province, cropping out at the eastern São Paulo state. It is made up of basic-intermediate rocks with a great diversity of structures, textures and modal compositions, related to specific evolutionary process in a magma chamber. Previous ge

2. Brazoides A-D, New Alkaloids from Justicia gendarussa Burm. F. Species
Four new alkaloids, Brazoides A-D, together with three known compounds squalene, β-sitosterol and lupeol, were isolated from leaves of Justicia gendarussa. These structures were established by spectrometric techniques, mainly high-resolution electrospray ionization mass spectrometry (HRESIMS) and 1D and 2D nuclear magnetic resonance (NMR), including compara

4. Electrochemical and Optical Investigation of Conductive Polymer and MWCNT Nanocomposite Film
Composites of multi-walled carbon nanotubes (MWCNT) and conductive polymer with good uniformity were prepared by electropolymerization. Molecular modeling calculations were carried out for electroactive monomer (OAP) polymerization with density functional theory (DFT) level using 6-311G(d,p) basis set for all atoms and Gaussian 03 program package. The reflec

5. Improvement of genistein content in solid genistein/-cyclodextrin complexes β
Genistein:β-cyclodextrin complexes with high drug loading (19.22%) were prepared by freeze-drying and characterized by differential scanning calorimetry and hydrogen nuclear magnetic resonance spectroscopy. The spatial configuration of the complex was proposed by means of 2D-NOESY experiment combined with molecular modeling. According to the results obtaine

6. A SPINE 3D MODELING SYSTEM BASED ON X-RAY IMAGES / UM SISTEMA DE MODELAGEM 3D DE COLUNA VERTEBRAL BASEADO EM IMAGENS DE RAIOS-X
Research involving computer graphics and laboratory exams has contributed much to the quality of the Medical diagnose. One aspect of these researches is directly related to 3D reconstruction of anatomical structures of the human body, especially the spine. The sedentary lifestyle and the high dependence of computers have increased the postural problems of th

8. Gephysical Characterization of the Araguainha impact structure, MT/GO. / Caracterização geofísica da estrutura de impacto de Araguainha, MT/GO
Araguainha is the largest and the best-exposed complex crater of South America, formed in horizontal sediments of the Paraná Basin. Its portentous structure with 40 km in diameter and 25 km of transient cavity reveals a negative contrast of density and magnetic susceptibility in the central uplift. That feature allows to infer a limit of physical property b

9. Estudo de irregularidades ionosféricas em períodos de baixa ocorrência em baixas latitudes sob condições calmas / Studies of low-latitude ionospheric irregularities during the periods of their low frequency of occurrence, and under quiet conditions
This thesis research focalises a study of the mechanisms involved in the generation and evolution of the ionospheric plasma bubbles by means of experimental data and modeling. The experimental data were obtained by night airglow (OI630nm) imagers and Digisondes. The airglow allsky imager was located at São João do Cariri (7,5°S, 36,5°O, I=-20°), and the

10. MODELAGEM E INVERSÃO 2D DE DADOS MAGNETOMÉTRICOS APLICADOS NA CARACTERIZAÇÃO DA GEOMETRIA DO SINCLINAL GANDARELA E HOMOCLINAL CURRAL QUADRILÁTERO FERRÍFERO, MG
The aim of the present study is the geometrical characterization of Gandarela syncline and Curral homocline, the major structures in the Quadrilátero Ferrífero, based on an integrated analysis of geophysical data. The Gandarela syncline is a reclined fold with NE-SW trending axial trace and hinge zone plunging to southeastern. The Curral homocline is repre

12. Space weather impact on magnetosphere: new helium radiation belt storm time formation
The consequences of the March 1991 storm on the Earth's radiation environment are now well known through many in-situ magnetospheric observations. Measurement from the CRRES spacecraft show the sudden formation of a new Helium ion structure deep within the magnetosphere. In that event, two additional new radiation belts were created, one containing large flu
