3. SEGMENTING TECHNIQUES OF IMAGES IN THE GENERATION OF PROGRAMS FOR MACHINERY OF COMMAND NUMERICAL / TÉCNICAS DE SEGMENTAÇÃO DE IMAGENS NA GERAÇÃO DE PROGRAMAS PARA MÁQUINAS DE COMANDO NUMÉRICO
This work describes a tool for extraction of features in 2D images applied to industrial automation. The method uses techniques implemented targeting of images into pieces model as detection of edges in the extraction of spatial coordinates of the image and import applications in CAD (Computer-Aided Design) for the generation of programmers for Computer Nume

4. Structural panel project for social housing making use of small diameter round-wood: product development / Painéis estruturais utilizando madeira roliça de pequeno diâmetro para habitação social: desenvolvimento do produto
The purpose of this work is to identify, from the analysis of the production chain of forest based products, the chances of making use of small diameter round-wood of the Eucalyptus and Pinus types, for the production of sealing structural panels destined for social housing. Wood as a renewable building material and, in accordance with the environmental a

5. The second negation of the work process / A segunda negação do processo de trabalho
This work searchs to analyze as if it gave the process of subordination of the work to the capital since century XVI until the present. The starting point of the analysis is the simple cooperation and the manufacture. In this situation, the worker only is formal subordinate to the capital. This if gives for the prolongation of the hours of working and for th

6. Construção de uma bancada de ensaio e avaliação de um sistema de mensuração da produtividade de grãos. / Construction of a laboratory bench and evaluation of a grain yield monitor.
With the progress of the precision agriculture where spatial yield variability is taken into account, it is necessary to improve data collection so the results can be more reliable. It is necessary to understand how yield sensor used on combines works in order to know the accuracy of the field data for generation of the yield maps. This work aims to characte

7. Transcriptionally competent chromatin assembled with exogenous histones in a yeast whole cell extract
We describe a cell-free chromatin assembly system derived from the yeast Saccharomyces cerevisiae, which efficiently packages DNA into minichromosomes in a reaction dependent on exogenous core histones and an ATP-regenerating system. Both supercoiled and relaxed plasmid DNA serve as templates for nucleosomal loading in a gradual process that takes at least 6

8. Ca2+ marks: Miniature calcium signals in single mitochondria driven by ryanodine receptors
Propagation of cytosolic [Ca2+] ([Ca2+]c) signals to the mitochondria is believed to be supported by a local communication between Ca2+ release channels and adjacent mitochondrial Ca2+ uptake sites, but the signaling machinery has not been explored at the level of elementary Ca2+ release events. Here, we demonstrate that [Ca2+]c sparks mediated by ryanodine

9. Chaperone action in the posttranslational topological reorientation of the hepatitis B virus large envelope protein: Implications for translocational regulation
The large L envelope protein of the hepatitis B virus utilizes a new folding pathway to acquire a dual transmembrane topology in the endoplasmic reticulum (ER). The process involves cotranslational membrane integration and subsequent posttranslational translocation of its preS subdomain into the ER. Here, we demonstrate that the conformational and functional
