13C ss-NMR Singular value decomposition and fitting for sorghum proteins conformation elucidation. Author(s): RIBEIRO, T. S.; SCRAMIN, J. A.; RODRIGUES, J. A. S.; BERNARDES FILHO, R.; COLNAGO, L. A.; FORATO, L. A. Kafirins, water-insoluble proteins from Sweet Sorghum BR501 grains, have been an alternative to prepare edible coatings for food due to their hydrophobic character. In this work, the secondary structu... ... Repository: BDPA Publication year: 2022
13C NMR and EPR spectroscopic evaluation of oil shale mined soil recuperation. Author(s): SANTOS, J. V. dos; MANGRICH, A. S.; PEREIRA, B. F.; PILLON, C. N.; NOVOTNY, E. H.; BONAGAMBA, T. J.; ABBT-BRAUNG, G.; FRIMMEL, F. H.

Insights into the composition of humin from an irish grassland soil. Author(s): BYRNE, C. M.; NOVOTNY, E. H.; HATCHER, P. G.; HAYES, M. H. B. Humin is defined as the fraction of the humic substances (HS) that is insoluble in aqueous solution at any pH value (1). Because of its insolubility it has been the least studied of all the humic frac... ... Repository: BDPA Publication year: 2008
Char and humin fractions in Amazonian dark earths. Author(s): SONG, G.; NOVOTNY, E. H.; HAYES, M. H. B.; AZEVEDO, E. R. de; BONAGAMBA, T. J. The high and specific SOM contents of the Amazonian Dark Earths (ADE, Terra Preta de Índios), and their high contents of P and Ca provide high natural fertility to the soils. Char or black carbon (B C... ... Repository: BDPA Publication year: 2008
