Study Of Optical Absorption, Visible Emission And Nir-vis Luminescence Spectra Of Tm3+/yb3+, Ho3+/yb3+ And Tm3+/ho3+/yb3+ Doped Tellurite Glasses
(ELSEVIER SCIENCE BVAMSTERDAM, 2015)
A gallery of bubbles The nature of the bubbles observed by Spitzer and what ATLASGAL tells us about the surrounding neutral material
(2010-12)
Context. This study deals with infrared bubbles, the H II regions they enclose, and triggered massive-star formation on their borders.
Aims. We attempt to determine the nature of the bubbles observed by Spitzer in the ...
Temporal variability of soil CO2 emission contrasting degraded and managed pasture in Brazil
(Elsevier B.V., 2015-01-01)
Grazing areas represent the largest agricultural areas in Brazil, occupying more than 172 million hectares, about 20% of the agricultural land (IBGE, 2007). Despite the large areas of degraded pasture, little information ...
Impact of plastic deformation on magnetoacoustic properties of Fe-2%Si alloy
(ELSEVIER SCI LTD, 2009)
The paper presents the results of a complementary study including magnetic hysteresis loops B(H), magnetic Barkhausen noise (MBN) and magnetoacoustic emission (MAE) signals measurements for plastically deformed Fe-2%Si ...
Efficient energy upconversion emission in Tm3+/Yb3+-codoped TeO2-based optical glasses excited at 1.064 mu m
(American Institute of Physics (AIP), 2014)
Shorter wavelength emission with InAs quantum dots growth directly on large bandgap quaternary (In0.68Ga0.32As0.7P0.3) barriers for high current injection efficiency
(Elsevier Science BvAmsterdamHolanda, 2010)
Spatial variability models of CO2 emissions from soils colonized by grass (Deschampsia antarctica) and moss (Sanionia uncinata) in Admiralty Bay, King George Island
(Cambridge University Press, 2011-02-01)
Soil CO2 emission is an important part of the terrestrial carbon cycling and is influenced by several factors, such as type and distribution of vegetation. In this work we evaluated the spatial variability of soil CO2 ...

Spatial and temporal variability of soil CO2 emission in a sugarcane area under green and slash-and-burn managements
(Elsevier B.V., 2009-11-01)
Soil management causes changes in physical, chemical, and biological properties that consequently affect soil CO2 emission (FCO2). Here, we studied the soil carbon dynamics in areas with sugarcane production in southern ...
