Spectroscopy of old nova candidates
(Tovmassian, G.Sion, E., 2004)
We present optical spectroscopy for severalold nova candidates that hitherto lacked suchobservations. V842 Cen, V630 Sgr, XX Tau,CQ Vel, and V840 Oph show typical CV spec-tra, but V529 Ori is probably misclassified.V630 Sgr ...
Sazonalidade e as redes de interações planta-polinizador
(Universidade Estadual Paulista (Unesp), 2011-08-31)
Os padrões de floração no nível de comunidade podem afetar a dinâmica dos sistemas ecológicos. Dessa formam a caracterização dos modos de polinização e padrões de floração no nível de comunidade são fundamentais para ...

Spectral imaging of the Sagittarius B2 region in multiple 7-mm molecular lines
(2011)
We have undertaken a spectral-line imaging survey of a 6 × 6 arcmin 2 area around Sagittarius (Sgr) B2 near the centre of the Galaxy, in the range from 30 to 50 GHz, using the Mopra telescope. The spatial resolution varies ...
Sistema general de regalías: nuevos recursos para la ciencia, tecnología e innovación en Colombia
(Instituto Tecnológico Metropolitano - ITM, 2015-01-22)
Este artículo presenta un balance de la implementación del Fondo de Ciencia, Tecnología e Innovación del Sistema General de Regalías en Colombia (FCTeI-SGR). La entrada en vigencia del SGR y la respectiva creación del ...
Ground Penetrating Radar Attenuation Expressions in Shallow Groundwater Research
(Society of Exploration Geophysicists, 2020-03-01)
The electromagnetic-wave attenuation coefficient determines the overall resolution and effective penetration depth of ground penetrating radar (GPR) surveys. Despite this relevance to the design of proper GPR surveys, the ...
Longer wavelengths of light improve the growth, intake and feed efficiency of individually reared juvenile pikeperch Sander lucioperca (L.)
(Wiley-Blackwell Publishing, Inc, 2009-05-22)
We tested the effects of monochromatic light on the specific growth rate (SGR), feed intake and feed efficiency (FE) of juvenile pikeperch, Sander lucioperca (L.). Pikeperch were reared individually for 42 days in aquaria ...

First very low frequency detection of short repeated burstds from MAGNETAR SGR J1550−5418
(American Astronomical Society, 2010-08)
We report on the first detection of ionospheric disturbances caused by short repeated gamma-ray bursts from the magnetar SGR J1550−5418. Very low frequency (VLF) radio wave data obtained in South America clearly show sudden ...
