The Recovery Phase after the 2009.0-event of eta Carinae
(Konkoly Observatory, 2009-12)
The 5.5 years periodicity of eta Carinae is manifested in the "events" observed in different wavelength ranges. The last of these "events" occurred as expected in 2009.0. Our ground-based photometric campaign registered ...
Cosmic distance duality relation and the shape of galaxy clusters
(EDP SCIENCES S A, 2011)
Context. Observations in the cosmological domain are heavily dependent on the validity of the cosmic distance-duality (DD) relation, eta = D(L)(z)(1+ z)(2)/D(A)(z) = 1, an exact result required by the Etherington reciprocity ...
The periodicity of the eta Carinae events
(WILEY-BLACKWELL, 2008)
Extensive spectral observations of eta Carinae over the last cycle, and particularly around the 2003.5 low-excitation event, have been obtained. The variability of both narrow and broad lines, when combined with data taken ...
Experiments using new initial soil moisture conditions and soil map in the Eta model over La Plata Basin
(Springer Wien, 2013-07)
An effort towards a more accurate representation of soil moisture and its impact on the modeling of weather systems is presented. Sensitivity tests of precipitation to soil type and soil moisture changes are carried out ...
Zonda downslope winds in the central Andes of South America in a 20-year climate simulation with the Eta model
(Springer Wien, 2017-04)
The Zonda wind is a local version of the alpine foehn in the central Andes Mountains in South America. It blows on the eastern slopes and produces an extremely warm and dry condition in Argentina. In this study, the ...
A multispectral view of the periodic events in Eta Carinae
(Wiley Blackwell Publishing, Inc, 2008-06)
A full description of the 5.5-yr low excitation events in η Carinae is presented. We show that they are not as simple and brief as previously thought, but a combination of two components. The first, the slow variation ...
Produção de água em ETA com alteração da carreira de filtração
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA SANITÁRIA, 2017-04-20)
Water treatment plants are designed according to the water quality on source, which directly sets up the treatment technology to be used and consequently influences costs of operation and maintenance. The adequacy of the ...
Effects of weld strength mismatch on J and CTOD estimation procedure for SE(B) specimens
(SPRINGER, 2009)
This work examines the effect of weld strength mismatch on fracture toughness measurements defined by J and CTOD fracture parameters using single edge notch bend (SE(B)) specimens. A central objective of the present study ...
