2. Generation of Non-diffraction Vortex Beam and Its Application in Digital Communication
Abstract An axicon-frustum basin-type Bessel resonator is designed for generating non-diffraction vortex beams with opposite propagation directions under different conditions. Based on the theory of geometric optics, the principle of creating vortex beams is analyzed in this axicon-frustum basin-shaped resonant cavity. It is shown that a non-diffraction vort

3. Monitoring of Sobradinho landslide (Brasília, Brazil) and a prototype vertical slope by time-lapse interferometry
Abstract The application of geophysical monitoring technologies may offer an opportunity to understand the dynamic of slopes in response to factors triggering their instability. In this study, Ambient Noise Interferometry was used as a monitoring approach on a man-made reduced-scale vertical slope and on a natural-scale landslide in Sobradinho (Brazil), unde

4. SPATIAL VARIABILITY OF THE MICROCLIMATE IN DIFFERENT SMALL RUMINANT HOUSE LOCATED IN THE SEMIARID OF PERNAMBUCO, BRAZIL
ABSTRACT The spatial variability in meteorological conditions was evaluated in two small ruminant house with different constructive aspects, based on the variables of dry bulb temperature, relative humidity, wind speed and temperature humidity index (THI), through the generation of maps using the Kriging interpolation method. The experiment was conducted in

5. Absorbed doses in salivary and thyroid glands from panoramic radiography and cone beam computed tomography
Abstract Introduction: Panoramic radiography and cone beam computed tomography (CBCT) are very important in the diagnosis of oral diseases, however patients are exposed to the risk of ionizing radiation. This paper describes our study aimed at comparing absorbed doses in the salivary glands and thyroid due to panoramic radiography and CBCT and estimating ra

6. Energy generation in a Microbial Fuel Cell using anaerobic sludge from a wastewater treatment plant
ABSTRACT In microbial fuel cells (MFCs), the oxidation of organic compounds catalyzed by microorganisms (anode) generates electricity via electron transfer to an external circuit that acts as an electron acceptor (cathode). Microbial fuel cells differ in terms of the microorganisms employed and the nature of the oxidized organic compound. In this study, a co

8. Networks of desire: the specter of AIDS and the use of digital media in the quest for secret same-sex relations in São Paulo
This article seeks to analyze the emergence of an on-line market for love and sex partners in São Paulo, as of 1997, when the internet became commercially available in Brazil. Focusing on the first generation of digital media users, my field research looks at men who entered adolescence or adulthood during the AIDS epidemic. I analyze how the use of digital

9. Integração entre redes heterogêneas de ativos digitais: modelo híbrido de metadados baseado em meta-modelos dinâmicos
The increased production of digital assets in enterprise environments makes digital asset management an increasingly complex task, since we must make use of well-defined metadata, so that you can easily find and use assets from different repositories. However, obtaining a standardized model that cover the peculiarities of all involved, is usually a highly co
