1. Preparation of Fluorescent Carbon-Based Dots from Waste Tire Pyrolysis
The pyrolysis of waste tire has been proposed as an alternative route to its recycling producing residual oils that can be used as fuels. In this work, a physicochemical process to obtain carbon-based dots (CBD) from carbon black (CBL) derivatives of tires is described. For this, the CBL was treated with different acids to produce CBL1 and CBL2 particles sus

2. Photonic Imaging with Optical Coherence Tomography for Quality Monitoring in the Poultry Industry: a Preliminary Study
ABSTRACTA photonic imaging method that gives the possibility to measure egg quality was applied. Since the method is non-contact and non-destructive we believe that this photonic imaging method may be successfully integrated in the automated inspection systems in the poultry industry. The method involves scanning an invisible infrared light beam over the egg

3. Evaluation of a linear spectral mixture model and vegetation indices (NDVI and EVI) in a study of schistosomiasis mansoni and Biomphalaria glabrata distribution in the state of Minas Gerais, Brazil
This paper analyses the associations between Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) on the prevalence of schistosomiasis and the presence of Biomphalaria glabrata in the state of Minas Gerais (MG), Brazil. Additionally, vegetation, soil and shade fraction images were created using a Linear Spectral Mixture Model (LS

4. Acidentes de trabalho: a caracterização objetiva das lesões por esforço repetitivo (LER)
O presente trabalho aborda questões sobre acidentes de trabalho, especificamente as Lesões por Esforço Repetitivo (LER), suas implicações sociais e a dificuldade da prova quanto à extensão e caracterização de tais lesões pelo perito. Destaca-se o ônus que a Previdência Social sofre em virtude dos acidentes de trabalho. Desta forma, extrai-se a pr

5. Estimação da resolução espacial da câmera CCD dos satélites CBERS 1 e 2 / Spatial resolution estimation of CBERS CCD camera
The first China-Brazil Earth Resources Satellite (CBERS-1) was launched in 1999 and was substituted on 2003 by CBERS-2. CBERS- 1 and CBERS-2 have the same specifications and carry three sensors: a Wide Field Imager (WFI), a High Resolution CCD Camera (CCD) and an Infrared Multispectral Scanner (IRMSS). Due to the limitations of the sensor components (diffrac

6. Assessing atherosclerotic plaque morphology: comparison of optical coherence tomography and high frequency intravascular ultrasound.
BACKGROUND: OCT can image plaque microstructure at a level of resolution not previously demonstrated with other imaging techniques because it uses infrared light rather than acoustic waves. OBJECTIVES: To compare optical coherence tomography (OCT) and intravascular ultrasound (IVUS) imaging of in vitro atherosclerotic plaques. METHODS: Segments of abdominal

7. Cortical functional architecture and local coupling between neuronal activity and the microcirculation revealed by in vivo high-resolution optical imaging of intrinsic signals.
We have shown previously the existence of small, activity-dependent changes in intrinsic optical properties of cortex that are useful for optical imaging of cortical functional architecture. In this study we introduce a higher resolution optical imaging system that offers spatial and temporal resolution exceeding that achieved by most alternative imaging tec

8. Noninvasive assessment of the developing Xenopus cardiovascular system using optical coherence tomography
Studies investigating normal and abnormal cardiac development are frequently limited by an inability to assess cardiovascular function within the intact organism. In this work, optical coherence tomography (OCT), a new method of micron-scale, noninvasive imaging based on the measurement of backscattered infrared light, was introduced for the high resolution
