3. An optimization approach of dynamic maceration of Centella asiatica to obtain the highest content of four centelloids by response surface methodology
ABSTRACT Centella asiatica (L.) Urb., Apiaceae, is commonly used as food, food supplement, and medicine. Development of the extraction process to obtain the high extent of the active compound is necessary. So, the response surface methodology was used in this work to optimize the dynamic maceration of C. asiatica to obtain the highest content of the four cen

4. Geophysical modeling in gold deposit through DC Resistivity and Induced Polarization methods
Abstract Ore mining fundamentally depends on the definition of its tenor and volume, something extremely complex in disseminated mineralization, as in the case of certain types of deposits of gold and sulfites. This article proposes the use of electrical tomography for definition of a geophysical signature in terms of electrical resistivity and chargeability

5. Lung disease detection using feature extraction and extreme learning machine
INTRODUCTION: The World Health Organization estimates that by 2030 the Chronic Obstructive Pulmonary Disease (COPD) will be the third leading cause of death worldwide. Computerized Tomography (CT) images of lungs comprise a number of structures that are relevant for pulmonary disease diagnosis and analysis. METHODS: In this paper, we employ the Adaptive Cris

6. Segmenting mammographic microcalcifications using a semi-automatic procedure based on Otsu's method and morphological filters
INTRODUCTION: Breast cancer has the second highest world's incidence rate, according to the Brazilian National Cancer Institute (INCa). Clinical examination and mammography are the best methods for early diagnosis. Computer-aided detection (CADe) and computer-aided diagnosis (CADx) systems are developed to improve mammographic diagnosis. Basically, CADx syst

7. Extração de contornos de figuras via sincronismo em redes de osciladores com acoplamento dinâmico
Uma variante do modelo de Kuramoto para osciladores de fase com acoplamento dinâmico é estudada. A intensidade do acoplamento é ajustada pela diferença de fases dos osciladores, de forma que a conexão é reforçada para osciladores sincronizados e enfraquecida para osciladores não sincronizados. As soluções de equilíbrio e suas estabilidades são ap

8. Expansionbydilationanderosionwithaviewtoskeletonandcontourextractionindigitalimages / Expansão por dilatação e por erosão visando a extração de esqueletos e contornos em imagens digitais
The motivation of this work comes from the observation of some discrete plane limitations, especially those related with the skeleton and contour extraction. The objective is to overcome these limitations. The methodology consists of using domain transformations. The main contribution is the introduction of an expansion for labeled images and the study of it

9. Extração de fatores de intensidade de tensão utilizando a solução do método dos elementos finitos generalizados / Extraction of stress intensity factors from generalized finite element solutions
O trabalho apresenta uma análise do desempenho de vários métodos de extração de fatores de intensidade de tensão a partir de soluções numéricas obtidas com o método dos elementos finitos generalizados (MEFG). A convergência dos fatores de intensidade de tensão é comparada com a da energia de deformação a fim de investigar a superconvergência

11. Titin elasticity and mechanism of passive force development in rat cardiac myocytes probed by thin-filament extraction.
Titin (also known as connectin) is a giant filamentous protein whose elastic properties greatly contribute to the passive force in muscle. In the sarcomere, the elastic I-band segment of titin may interact with the thin filaments, possibly affecting the molecule's elastic behavior. Indeed, several studies have indicated that interactions between titin and ac

12. The effect of partial extraction of troponin C on the elementary steps of the cross-bridge cycle in rabbit psoas muscle fibers.
The elementary steps of the cross-bridge cycle in which troponin C (TnC) was partially extracted were investigated by sinusoidal analysis in rabbit psoas muscle fibers. The effects of MgATP and phosphate on the rate constants of exponential processes were studied at 200 mM ionic strength, pCa 4.20, pH 7.00, and at 20 degrees C. The results were analyzed with
