Biomassa e nutrientes em um povoamento de Eucalyptus saligna Smith submetido ao primeiro desbaste
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2013-02-26)
Eucalyptus is one of the most cultivated species in Brazil due to its fast increment and adaptation to the various types of soils and its characteristics related to the climate. In the county of Rio Grande do Sul (RS), the ...
Monitoring of engine oil aging by diffusion and low-field nuclear magnetic resonance relaxation
(Elsevier, 2019-04)
Time domain, also named lowfield nuclear magnetic resonance is used to monitor oil degradation by measuring relaxation and diffusion. As quality control of oils is indispensable to optimize oil change intervals while ...
Physical-chemical and microbiological changes in Cerrado Soil under differing sugarcane harvest management systems
(BIOMED CENTRAL LTDLONDON, 2012)
Background: Sugarcane cultivation plays an important role in Brazilian economy, and it is expanding fast, mainly due to the increasing demand for ethanol production. In order to understand the impact of sugarcane cultivation ...
Swimming versus swinging effects in spacetime
(2006-01-15)
Wisdom has recently unveiled a new relativistic effect, called aœspacetime swimminga, where quasirigid free bodies in curved spacetimes can aœspeed upa, aœslow downa or aœdeviatea their falls by performing local cyclic ...
Rupture processes of the 2012 September 5 Mw 7.6 Nicoya, Costa Rica earthquake constrained by improved geodetic and seismological observations
(2015-08-17)
On 2012 September 5, the anticipated interplate thrust earthquake ruptured beneath the Nicoya peninsula in northwestern Costa Rica close to the Middle America trench, with a magnitude Mw 7.6. Extensive co-seismic observations ...

Origin of magnetism in early-type stars. Protostellar magnetic fields and core dynamo.
(Universidad de ConcepciónFacultad de Ciencias Físicas y Matemáticas.Departamento de AstronomíaConcepción., 2023)
Early-type stars have radiative envelopes and convective cores due to a steep temperature gradient produced by the CNO cycle. The chemically peculiar Ap and Bp stars host large-scale magnetic fields in the order of 200 G ...
Topological Analysis of Emerging Bipole Clusters Producing Violent Solar Events
(Springer, 2014-06)
During the rising phase of Solar Cycle 24 tremendous activity occurred on the Sun with fast and compact emergence of magnetic flux leading to bursts of flares (C to M and even X-class). We investigate the violent events ...
20 Years of ACE Data: How Superposed Epoch Analyses Reveal Generic Features in Interplanetary CME Profiles
(Blackwell Publishing Ltd, 2020-10)
Interplanetary coronal mass ejections (ICMEs) are magnetic structures propagating from the Sun's corona to the interplanetary medium. With over 20 years of observations at the L1 libration point, ACE offers hundreds of ...
