Gamma Radiation Effects on Polydimethylsilane Stationary Phases for Use in Packed-Column Gas Chromatographic Analyses

Este trabalho estudou os efeitos da radiação gama como indutora da imobilização de fases estacionárias líquidas de polidimetilsilicones usadas para separações cromatográficas em colunas recheadas. Testes de extração em solventes mostram que doses moderadas de radiação gama (80-140 kGy) produzem imobilização (90%) da maioria dos polidimetilsilicones testados em suportes do tipo Chromosorb, apesa...

Otimização do controle do diagrama de radiação de radares de varredura para rastreio de foguetes usando o método GAMMC para o Caso Planar (GAMMC-P)

Launching centers are designed for scientific and commercial activities with aerospace vehicles. Rocket Tracking Systems (RTS) are part of the infrastructure of these centers, being responsible for collecting and processing the data trajectory of such vehicles. Generally, Parabolic Reflector Radars (PRRs) are used in RTS. However, it is possible to use radars with antenna arrays, or Phased Arra...

GAMA-Mall - Shopping in Communities

In this article, we consider market places as social places. Social places provide social presence and interaction. Virtual market places often lack in these social factors. Community support tools, such as chat systems or newsgroups try to fill this gap. We argue that a new architecture is needed that brings together customers with common interests. We propose a combined system called GAMA-Mal...

Galaxy And Mass Assembly (GAMA)

The GAMA survey aims to deliver 250,000 optical spectra (3–7Å resolution) over 250 sq. degrees to spectroscopic limits of rAB < 19.8 and KAB < 17.0 mag. Complementary imaging will be provided by GALEX, VST, UKIRT, VISTA, HERSCHEL and ASKAP to comparable flux levels leading to a definitive multi-wavelength galaxy database. The data will be used to study all aspects of cosmic structures on 1kpc t...
