Bulk Prepolymerization of Styrene in the Presence of Polybutadiene. Comparision with an Equivalent Solution Polymerization and Development Of an Extended Mathematical Model
(John Wiley & Sons Inc, 2009-01)
The bulk prepolymerization of styrene in the presence of polybutadiene for the production of highimpact polystyrene is analyzed and compared with an equivalent solution reaction described by Estenoz et al. in 1999. The ...
Biodegradation of acidolysis lignins from Chilean hardwoods by the ascomycete Chrysonilia sitophila
(SpringerNew YorkEUA, 1997)
Further characterization of the subunits of the giant extracellular hemoglobin of Glossoscolex paulistus (HbGp) by SDS-PAGE electrophoresis and MALDI-TOF-MS
Further characterization of hemoglobin of Glossoscolex paulistus (HbGp) subunits was performed based on SDS-PAGE, size exclusion chromatography (SEC) and MALDI-TOF-MS analysis. SDS-PAGE has shown a total of four linker ...
Rapid, quantitative determination of polar compounds in fats and oils by solid-phase extraction and size-exclusion chromatography using monostearin as internal standard
A rapid and simple method was developed for quantitation of polar compounds in fats and oils using monostearin as internal standard. Starting from 50 mg of oil sample, polar compounds were obtained by solid-phase extraction ...
Caracterização da estrutura molecular e propriedades viscográficas de amidos de mandioca (Manihot esculenta Crantz) para aplicações industriais
(Universidade Estadual Paulista (UNESP), 2004-11-09)
A fécula de mandioca (Manihot esculenta Crantz) contém aproximadamente 98 % de amido, em peso seco. Este amido é constituído por dois tipos de polissacarídeos: a amilose ( de 16 a 20 % ), com cadeias lineares de monômeros ...
Biophysical characterization of the recombinant importin-α from neurospora crassa
Neurospora crassa has been widely used as a model organism and contributed to the development of biochemistry and molecular biology by allowing the identification of many metabolic pathways and mechanisms responsible for ...
