3. MAPAS DE DENSIDADE E VELOCIDADE E ESTIMATIVA DE DISTÂNCIA DA REGIÃO H II GALÁCTICA NGC 2579
An observational study was accomplished about the range of eletron density in the HIIregion NGC 2579 and estimate its distance from the 8un and from the centre of the Galaxy. Long slit spectrophotometric data with high noise signal in the 6000 to 7000 Á were obtained by using the 1.60 m telescope of the Laboratório Nacional de Astrofísica LNA), MG. We obs

4. The physiological basis of heterochromatic flicker photometry demonstrated in the ganglion cells of the macaque retina.
1. Heterochromatic flicker photometry is a way of measuring the spectral sensitivity of the human eye. Two lights of different colour are sinusoidally alternated at, typically, 10-20 Hz, and their relative intensities adjusted by the observer until the sensation of flicker is minimized. This technique has been used to define the human photopic luminosity, or

5. Permeability Properties of Rickettsia mooseri
The passive permeability properties of Rickettsia mooseri to both inorganic and organic solutes have been examined. Visual observations by phase-contrast microscopy of rickettsiae in macerated yolk sacs taken directly from heavily infected eggs revealed plasmolysis with hypertonic NaCl and KCl as well as with sucrose solutions. In contrast, similar visual st
