We initially investigate some processes that affect the stellar atmosphere, such as the gravity-brightening and limb-darkening, and the influence of the reflection effect on them. We study the gravity-brightening exponents ...

Slow waves are commonly observed on the entire solar atmosphere. Assuming a thin flux tube approximation, the cut-off periods of slow-mode magneto-acoustic-gravity waves that travel from the photosphere to the corona were ...

The aim of this study was to determine the genetic variation of growth traits, wood basic density, dry mass of crown, leaf, and stem, and carbon stock within and between two Genipa americana L. provenances. The provenance ...

As variações de umidade e da densidade do lenho das árvores são as principais causas dos defeitos de secagem, como o empenamento e fendilhamento das peças de madeira. Os tipos de madeira presentes em um tronco estão ...

Esta tesis tuvo como objetivo identificar posibles efectos cuántico-gravitacionales al estudiar sistemas astrofísicos, en el contexto de un marco teórico estructurado idealizado para someter al escrutinio de la naturaleza ...

Despite present efforts to better understand glacier changes and their trends, the satellite gravimetry is a powerful tool still not applied in-depth to study relatively large areas in the Andes of Argentina and Chile. In ...

The performance of orifice plates in real-time monitoring of oil, gas and water standard flow rates was investigated. To this end, a multi-rate test was implemented in two production wells routed individually to a test ...

Guapuruvu (Schizolobium parahyba (Vell) Blake) is a native species of Atlantic Forest that has rapid development and large gain in volume. Some pioneers studies about the technological potential of guapuruvu's wood ...
