The chemical nature of the surface of a granular activated carbon has been modified by heat treatment under nitrogen at 1000 °C followed by pyrolysis of propene in the 300–600 °C temperature range. Cracking of propene produces deposits of coke…

We report the results of an experimental-theoretical study on the stopping power of ZrO2 films for swift H and He ion beams. The experiments, using the Rutherford Backscattering technique, were done for protons with incident energies in the range 200–1500…

We have determined “effective” Bethe coefficients and the mean excitation energy of stopping theory (I-value) for multiwalled carbon nanotubes (MWCNTs) and single-walled carbon nanotube (SWCNT) bundles based on a sum-rule constrained optical-data model energy loss function with improved asymptotic properties.…

In this paper we analyze the growth and early survival of two congeneric columnar cacti: the rare Neobuxbaumia macrocephala (with low population densities and a narrow distribution range), and the relatively common Neobuxbaumia mezcalaensis (with dense populations and a broader…

The coconut mite, Aceria guerreronis Keifer, has become one of the most important pests of coconut in the Americas and Africa and recently in Southeast Asia. Despite the great economic importance of this mite, there is a lack of information…

Growth and leaf nutrient content were compared in young potted plants of Copaifera langsdorffii in sunny and shaded areas without water stress. Besides, carbon assimilation and leaf water relations were evaluated by net photosynthesis, potential photochemical efficiency and leaf water…

Este trabalho teve por objetivo investigar os parâmetros relevantes para a estruturação de polpa de açaí, avaliando-se o efeito da combinação de diferentes hidrocoloides nas características do gel de fruta. Foi realizado planejamento experimental 23, em que as concentrações de…
