Tuning the photocatalytic activity of tin oxide through mechanical surface activation. Author(s): SILVA, F. B. F.; SILVA, G. T. S. T. da; TORRES, J. A.; OLIVEIRA, C. R. de Tin oxide (SnO2) nanoparticles were synthesized by the co-precipitation method and mechanically modified by high-energy ball milling. The experimental results demonstrate that the collision with zirco... ... Repository: BDPA Publication year: 2022
Germination of seeds of interspecific hybrid caiaué × oil palm submitted to the mechanical depulping. Author(s): MAQUINÉ, T. M.; CYSNE, A. Q.; LIMA, W. A. A. de; ABREU, S. C.; GREEN, M.; RIOS, S. de A. Oil palm seeds respond well to protocols of dormancy break, however, the seeds of interspecific hybrid (HIE) (caiaué × oil palm) have lower germination rates. The mechanical depulping can affect the p... ... Repository: BDPA Publication year: 2014
Physical and mechanical properties of Eucalyptus urophylla. Author(s): SCANAVACA JUNIOR, L.; GARCIA, J. N. Resumo: Eucalyptus urophylla is one of the most planted species in the world and in Brazil for presenting excellent productivity, good adaptability to the most varied types of soil and climate and wid... ...

Soil mechanical resistance to penetration (SMRP) in an Oxisol under different integrated crop/livestock systems (CLS). Author(s): SPERA, S. T.; MAGALHAES, C. A. de S.; FARIAS NETO, A. L. de; WOLF, G.; DORNELAS, K. C. The high values of SMRP indicate reduction of soil water infiltration and high levels of soil erosion. Integrated CLS include forest and pastures. The SMRP of soils managed with CLS can be affected by... ... Repository: BDPA Publication year: 2015
Mechanical properties of cassava starch films as affected by different plasticizers and different relative humidity conditions. Author(s): LAGOS, J. B.; VICENTINI, N. M.; SANTOS, R. M. C. dos; BITTANTE, A. M. Q. B.; SOBRAL, P. J. A. Repository: BDPA Publication year: 2015
Mechanisms underlying cowpea mosaic virus systemic infection. Author(s): SILVA, M. S. Systemic virus infection of plants involves intracellular replication, local spread within the inoculated leaf (cell-to-cell movement), and subsequently, long-distance spread to other plant parts via... ...
