1. Análise do speckle laser dinâmico: uma releitura / Dynamic speckle laser analysis: a review
A análise de imagem por si mesma se apresenta como um poderoso instrumento aplicado ao monitoramento a toda espécie de fenômenos biológicos. O desenvolvimento de diversos tipos de abordagens ópticas com o objetivo de se obter viabilidade na aquisição e análise de imagens tem sido um dos principais esforços nessa área de aplicação. Uma consequênc

2. Statistic Techniques applied in dynamic speckle images / TÃCNICAS ESTATÃSTICAS APLICADAS EM IMAGENS DO SPECKLE DINÃMICO
COSTA, Ricardo Marques da. Statistic Techniques applied in dynamic speckle images. 2009. 83 p. Dissertation (Mastering in Systems Engineering) - Universidade Federal de Lavras, Lavras, MG. Analysis of materials through laser beams and application of statistical analysis techniques are now fundamentally important in several science-related fields. In spite of

3. Desenvolvimento de modelo dinÃmico para o biospeckle / Development of a Dynamic Model for the Biospeckle.
In this work we developed a simple microscopic dynamic model to describe the main characteristics of the phenomenon known as dynamic speckle, or biospeckle. The biospeckle is an interference pattern produced when a sample of biological origin is illuminated with coherent light. The characteristics of the biospeckle have been investigated as possible tools fo

4. Efeito estocastico em Speckle dinamico / Stochastic effects on dynamics Speckle
This research work had the objective of contributing to the development of a methodology applicable to biological tissues vitality analysis by means of a stochastic model. The conceived and tested model is able to interpret as well as to quantify the biospeckle images generated on living tissues. The biospeckle or dynamic speckle phenomenon is generated from

5. Study of evolution of zinc phosphate cement´s setting reaction by laser, applying an optics technique of dynamic speckle / "Estudo da evolução da reação de presa do cimento de fosfato de zinco através de luz laser, aplicando a técnica óptica de speckle dinâmico"
The prosthesis cementation and/or other prosthetic elements, consists in permanent concern, since one of the major applications of zinc phosphate cement is as lutting agent. This study aims at the microstructural analyze to the evolution of the zinc phosphate cement´s setting reaction. More specifically, searched to verify, based on the known phenomenon as

6. Phosphoinositide Signaling Pathways in Nuclei Are Associated with Nuclear Speckles Containing Pre-mRNA Processing Factors
Phosphoinositide signal transduction pathways in nuclei use enzymes that are indistinguishable from their cytosolic analogues. We demonstrate that distinct phosphatidylinositol phosphate kinases (PIPKs), the type I and type II isoforms, are concentrated in nuclei of mammalian cells. The cytosolic and nuclear PIPKs display comparable activities toward the sub

7. Feedback Interactions between Cell–Cell Adherens Junctions and Cytoskeletal Dynamics in Newt Lung Epithelial CellsV⃞
To test how cell–cell contacts regulate microtubule (MT) and actin cytoskeletal dynamics, we examined dynamics in cells that were contacted on all sides with neighboring cells in an epithelial cell sheet that was undergoing migration as a wound-healing response. Dynamics were recorded using time-lapse digital fluorescence microscopy of microinjected, label
