Reverse order law for reflexive generalized inverses of products of matrices
(Elsevier Science IncNew YorkEUA, 1998)
Kinetic study of the thermal decomposition of cellulose nanocrystals with different polymorphs, cellulose I and II, extracted from different sources and using different types of acids
(Elsevier B.V., 2015-12-15)
Cellulose nanocrystals (CNs) were extracted from different sources by acid hydrolysis using H2SO4 and HCI. The thermal decomposition of resulting CNs was studied by thermogravimetric analysis (TGA). The kinetic parameters ...
Litter decomposition of emergent macrophytes in a floodplain marsh of the Lower Paraná River
(Elsevier Science, 2001-05-15)
The role of litter decomposition on organic matter accumulation and nutrient cycling was studied in a floodplain marsh of the Lower Paraná River by means of in situ litterbag experiments. The effect of waterborne nutrients ...
Thermal decomposition of some diuretic agents
(1996-05-01)
Thermogravimetry-derivative thermogravimetry and differential scanning calorimetry were used to study the thermal behaviour of furosemide, hydrochlorothiazide, spironolactone, and amiloride hydrochloride. The results ...

Thermal decomposition of some analgesic agents
(1996-06-01)
Thermogravimetry, derivative thermogravimetry (TG, DTG) and differential scanning calorimetry (DSC), were used to study the thermal behaviour of mefenamic acid, ibuprofen, acetaminophen, sodium diclofenac, phenylbutazone, ...
Determinantes locais da decomposição foliar e de raízes finas em um ecossistema semiárido do nordeste brasileiro
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em EcologiaBioecologia Aquática, 2012-02-22)
The decomposition process exercises an extensive control over the carbon cycle, affecting its availability and nutrient cycling in terrestrial ecosystems. The understanding of leaf decomposition patterns above the soil and ...
