13. A infidelidade na ótica de terapeutas de casal
One of the most common and serious tension that separates the families is infidelity. This subject is here analysed in order to understand what makes the human being commit adultery and what means are used by the couple to structure the conjugal relationship again. This qualitative study was made by the discourse analysis whose bases were built from the read

14. Carrier dynamics investigated by time resolved optical spectroscopy
We have investigated the transport of carriers in GaAs using time resolved optical spectroscopy with picosecond resolution. Carriers are optically created to the sample surface by an ultra-fast laser pulse. They diffuse and drift throught a thick GaAs layer, until they are captured by an InGaAs quantum well, where they recombine with holes from a p-type dope

15. Modelagem fenomenologica e simulação bidimensional de ciclones por tecnicas da fluidodinamica computacional
This work presents a mathematical modeling based on the principIes of mass and momentum conservation with the volumetric average point of view, and generalized to represent the multiphase flow in cyclones. It also discusses the hypotheses necessary for flutuating properties treatment, due to Reynolds decomposition applied as statistical treatment of the turb

16. Coupling of PAK-Interacting Exchange Factor PIX to GIT1 Promotes Focal Complex Disassembly
The p21-activated kinase PAK is targeted to focal complexes (FCs) through interactions with the SH3 domains of the PAK-interacting exchange factor PIX and Nck. PIX is a Rac GTP exchange factor that also binds the G-protein-coupled receptor kinase-interacting protein known as GIT1. Overexpression of GIT1 in fibroblasts or epithelial cells causes a loss of pax

17. Calcium-Actin Waves and Oscillations of Cellular Membranes
We propose a mechanism for the formation of membrane oscillations and traveling waves, which arise due to the coupling between the actin cytoskeleton and the calcium flux through the membrane. In our model, the fluid cell membrane has a mobile but constant population of proteins with a convex spontaneous curvature, which act as nucleators of actin polymeriza

18. Src-Mediated Phosphorylation of Focal Adhesion Kinase Couples Actin and Adhesion Dynamics to Survival Signaling
Integrin-associated focal adhesions not only provide adhesive links between cellular actin and extracellular matrix but also are sites of signal transmission into the cell interior. Many cell responses signal through focal adhesion kinase (FAK), often by integrin-induced autophosphorylation of FAK or phosphorylation by Src family kinases. Here, we used an in

19. Simulation of integrin-cytoskeletal interactions in migrating fibroblasts.
Cell migration is a dynamic phenomenon requiring a physical interaction between the internal cell motile machinery and the external substratum in which adhesion receptors, such as integrins, serve as the transmembrane link. To analyze quantitatively this interaction, we apply a modified Brownian dynamics algorithm to simulate cytoskeleton-mediated transport

20. Food-web structure and ecosystem services: insights from the Serengeti
The central organizing theme of this paper is to discuss the dynamics of the Serengeti grassland ecosystem from the perspective of recent developments in food-web theory. The seasonal rainfall patterns that characterize the East African climate create an annually oscillating, large-scale, spatial mosaic of feeding opportunities for the larger ungulates in th
