13. ImobilizaÃÃo covalente de concanavalina a em goma de sementes de Parkia pendula magnetizada e sua aplicaÃÃo biotecnolÃgica
Protein immobilization in water insoluble supports is an important tool in biotechnology. Meanwhile, support magnetization increases its potential application since a magnetic field can be used to separate the support from the reaction system and its reuse afterwards. Among the proteins immobilized special attention have been given for lectins, mainly Concan

14. MediÃÃo experimental e prediÃÃo da volatilidade de flex fuels
Oxygenated additives are added to gasoline to increase its antiknock properties. These compounds are substitutes for additives that are environmentally more aggressive, like tetraethyl lead. The oxygenated used in the Brazilian gasoline is the anhydrous ethanol 20% the 25%, which can affect the fuel properties strongly. In the last decade, the number of vehi

15. Desenvolvimento de um espectrofometro no infravermelho proximo com transformada de Hadamard
A near infrared spectrophotometer based on Hadamard multiplexed measurements has been developed. The instrument can operate in the range 800 to 1756 nm or 1756 to 2712 nm depending on the dispersion grating position. The spectrophotometer employs a linear mask with 255 elements. Each element is 0.250 mm wide and 4.0 mm height. The spectral measurement can be

16. Desidratação catalitica do etanol a eter etilico em alumina
Some thermodynamic aspects about ethanol dehydration reactions to ethylene and diethyl ether, in gas phase, are discussed. From a review of aluminasstructure, based on information about ethanol adsorption forms in this catalyst, and considering the various suggested versions for the mechanisms of ethanol dehydration rections, it is extracted a proposal mecha

17. Tuning the Elastic Modulus of Hydrated Collagen Fibrils
Systematic variation of solution conditions reveals that the elastic modulus (E) of individual collagen fibrils can be varied over a range of 2–200 MPa. Nanoindentation of reconstituted bovine Achilles tendon fibrils by atomic force microscopy (AFM) under different aqueous and ethanol environments was carried out. Titration of monovalent salts up to a conc

18. Investigation of the Effects of Hydroalcoholic Solutions on Textural and Rheological Properties of Various Controlled Release Grades of Hypromellose
Hypromellose (hydroxypropyl methylcellulose, HPMC) matrices are widely used in the formulation of sustained release dosage forms. The integrity and performance of an HPMC matrix formulation depends on rapid hydration and gel formation upon ingestion. Due to the recent alert issued by the Food and Drug Administration regarding the potential negative influence
