1. Métodos para otimização de abertura dinâmica da nova fonte de luz síncrotron brasileira - Sirius / Methods for optmisation of the dynamic aperture of the new Brazilian synchrotron light source
Um novo anel de armazenamento de elétrons está sendo projetado para a produção de luz síncrotron de alto brilho no Laboratório Nacional de Luz Síncrotron (LNLS), em Campinas. Para atingir um alto brilho, requer-se uma forte focalização do feixe, levando a fortes não-linearidades dos campos magnéticos, o que limita a região de estabilidade do movi

2. Estudo da capacidade de imageamento do protótipo do brazilian decimetric array (PBDA) / Study of the imaging capability of the prototype of brazilian decimetric array (PBDA)
The prototype of the Brazilian Decimetric Array - BDA, is a one-dimensional East-West array, with 5 antennas of 4 m in diameter, with baselines ranging from 18 to 216 m, operating frequencies 1,2 - 1,7 GHz and temporal resolution of ~105 ms. The array has produced since the beginning of operations and on a regular basis, fringe visibilities in its 10 pairs o

3. Estudo da dinâmica populacional do caranguejo-uçá, Ucides cordatus cordatus (LINNAEUS, 1763) (CRUSTACEA-DECAPODA-BRACHYURA), e dos efeitos de uma mortalidade em massa desta espécie em manguezais do Sul da Bahia / Study of the population dynamic of the mangrove crab, Ucides cordatus (LINNAEUS, 1753) (CRUSTACEA-DECAPODA-BRACHYURA_, and the effects of a mass mortality of this specie in Southern Bahia mangroves
The mangrove crab (Ucides cordatus cordatus) is an important fishing resource for the low income communities in Brazil and also plays a role for the environment in the mangrove ecosystem. Massive mortality events of this specie have been registered in many mangrove areas in the Northeast Region of Brazil. The first step of this work was realized from October

4. High precision system for magnetic field measurements of insertion devices of the Brazilian Synchroton Light Source / Sistema de alta precisão para as medições dos campos magneticos dispositivos de inserção do Laboratorio Nacional de Luz Sincroton
This Thesis was a consequence of the need for an accurate and precise magnetic field measurement bench for insertion devices characterization (IDs). Such devices are versatile radiation sources installed in Electron Storage Rings. From their magnetic field profile, they provide high photon fluxes, with broad or monochromatic spectrum, being possible, dependi

5. Multivariable robust control of an integrated nuclear power reactor
The design of the main control system of the CAREM nuclear power plant is presented. This plant is an inherently safe low-power nuclear reactor with natural convection on the primary coolant circuit and is self-pressurized with a steam dome on the top of the pressure vessel (PV). It is an integrated reactor as the whole primary coolant circuit is within the

6. Oscillations in Stomatal Conductance: The Influence of Environmental Gain
It is supposed that oscillations in stomatal conductance are associated with the dynamic properties of the loop in which rate of evaporation affects, through physiological processes, the aperture of stomata and stomatal aperture in turn affects rate of evaporation. It is therefore predicted that their occurrence must be influenced by the magnitude of what is

7. Real time imaging of single fluorophores on moving actin with an epifluorescence microscope.
Relatively simple modifications of an ordinary epifluorescence microscope have greatly reduced its background luminescence, allowing continuous and real time imaging of single fluorophores in an aqueous medium. Main modifications were changing the excitation light path and setting an aperture stop so that stray light does not scatter inside the microscope. A

8. Visual cortical input alters spatial tuning in monkey lateral geniculate nucleus cells.
The response of monkey lateral geniculate nucleus (l.g.n.) cells to flashing spots, annuli, and drifting sine-wave gratings were recorded with tungsten micro-electrodes. These stimuli were presented (a) monocularly, through an aperture in the centre of a radial grating, or (b) dichoptically, in which the spots or drifting gratings were presented to the domin
