1. Through-Bond and Through-Space Interactions in [2,2]Cyclophanes
The interpretation of the distortions of the electron distribution in [2,2]cyclophanes (22-CPs) is controversial. Some studies indicate that there is an accumulation of electron density (ρ) outside the cavity of 22-CPs. The nature of through-space (ts) interaction is still under debate. The relative importance of ts and through-bond (tb) is an open question

2. Spatial and temporal distribution of Gymnorhamphichthys rondoni (Gymnotiformes: Rhamphichthyidae) in a long-term study of an Amazonian terra firme stream, Leticia - Colombia
ABSTRACT Weakly electric fishes continually emit electric organ discharges (EOD) as a means of communication and localization of objects in their surroundings. Depending on water conductivity, the amplitude of the electric field generated is known to increase with decreases in electrical conductivity of the water. In Amazonian terra firme streams, water cond

5. Os objetivos das visitas escolares a um observatório astronômico na visão dos professores
Among the many issues that museums, science centers and other scientific popularization places may broach, the Astronomy is the branch than raises more curiosity and fascination between people of all ages. Thus, spaces that provide the teaching and the popularization of this science for several types of public, like the astronomical observatories, become imp

6. DinÃmica salarial dos trabalhadores da agropecuÃria brasileira: uma anÃlise de dados espaciais (1992-2009) / Wage dynamics of the farming brazilian workers: an analysis of space data (1992-2009)
The objective of this work is to examine the wages differences dynamics of the farming sector temporary and permanent workers, through the analysis of the wage behavior in the Brazilian states on the period from 1992 to 2009. For this it was used the Space Data Exploratory Analysis (AEDE), the space econometrical modeling and as source of data the National R

7. Inclusão de MRI e informação multigrid a priori para inferência bayesiana de fontes de M/EEG / MRI image and multigrid a priori information for bayesian M/EEG source localization
Functional Neuroimaging has evolved in the last few decades with the introduction of techniques such as Positron Emission Tomography or PET and Functional Magnetic Ressonance Image or fMRI [Belliveau et al., 1991]. These allow observing brain activity with a resolution of a few millimeters and, due to the nature of the signal, a time resolution of the order

8. Transport and circulation in the reproduction urban spatial: considerations on the subway of Rio de Janeiro / Transporte e circulação na reprodução espacial urbana: considerações sobre o metrô do Rio de Janeiro
This study aims to analyse the role performed by transports in the process of reproduction of the urban space, searching the comprehension of the relation between the enviroment built in the city and its scheme of circulation, resulting in a space of circulation in which the effectiveness is possible through a system of transport for this purpose developed.

11. Note on semiclassical uncertainty relations
An important manifestation of the Uncertainty Principle, one of the cornerstones of our present understanding of Nature, is that related to semiclassical localization in phase-space. We wish here to add some notes on the subject with reference to the canonical harmonic oscillator problem, with emphasis in the concepts of semiclassical Husimi distributions, t

12. Entanglement, bifurcation and chaos in the Jahn-Teller E x beta / Emaranhamento, bifurcação e caos no modelo de Jahn-Teller E x beta
In this work we realize a study of entanglement for the Jahn-Teller E Ä b model, wich describes the interaction of a qubit with an oscillator mode, and relate it with the bifurcation of the fixed point of the classical analogue of the model. We also study qualitatively the ocurrence of chaos and its variation as a function of the parameters of the system. W
