1. DIGITAL SIMULATION SYSTEM OF NEUTRON PARAMETERS OF THE TRIGA IPR-R1 NUCLEAR RESEARCH REACTOR / SISTEMA DIGITAL PARA SIMULAÇÃO DOS PARÂMETROS NEUTRÔNICOS DO REATOR NUCLEAR DE PESQUISA TRIGA IPR-1
The IPR-R1 TRIGA Mark I nuclear research reactor, at the Nuclear Technology Development Center (CDTN), is a pool type reactor cooling by light water. TRIGA reactors (Training, Research, Isotope, General Atomics) were designed for research, training and radioisotope production. The International Atomic Energy Agency (IAEA) recommends the use of safety and fri

2. A study of direct power control technics for three-phase rectifiers / Estudo de tÃcnicas de controle direto de potÃncia para retificadores trifÃsicos
Retificadores trifÃsicos controlados sÃo amplamente utilizados em aplicaÃÃes que requerem fluxo de potÃncia bidirecional. AlÃm disso, tÃm sido cada vez mais empregados a fim de se reduzir a poluiÃÃo harmÃnica na rede elÃtrica. Tradicionalmente, o controle destes retificadores à feito atravÃs da corrente, em referencial orientado pelo vetor tens�

3. Design desejante: a dobra como espaço e(ntr)e
When sound came to be part of the design universe, it became necessary to investigate in what measure design has changed its nature and has escaped from its (visual) common place, so as to deterritorialise in virtual spaces such as the space of music. We start from the principle that music and design not only can be of same nature as they can occupy the same

4. Construção, uso e disseminação da informação em grupos de pesquisa por meio de ambientes virtuais de colaboração.
The computers and the Internet in the universities and organisms of research have been shown as an element with potential for the dynamization of the construction, use and dissemination of the information for the collaborative work of the research groups. However, it is not evident the use of specialized information systems for support this modality of work.

5. Global air-sea flux of CO2: An estimate based on measurements of sea–air pCO2 difference
Approximately 250,000 measurements made for the pCO2 difference between surface water and the marine atmosphere, ΔpCO2, have been assembled for the global oceans. Observations made in the equatorial Pacific during El Nino events have been excluded from the data set. These observations are mapped on the global 4° × 5° grid for a single virtual calend

6. Osmotic Effects on the Electrical Properties of Arabidopsis Root Hair Vacuoles in Situ1
To assess the role of the vacuole in responses to hyperosmotic and hypo-osmotic stress, the electrical properties of the vacuole were measured in situ. A double-barrel micropipette was inserted into the vacuole for voltage clamping. A second double-barrel micropipette was inserted into the cytoplasm to provide a virtual ground that separated the electrical p
