Since then I have had yearly requests for copying rights. Hence, at the suggestions of colleagues, I have revised the older book to produce this text. The manuscript is currently being used in a graduate course at Virginia Tech in the Mechanical Engineering Department. As such, presentation materials for each chapter and a complete solutions manual are available for use by instructors. The text is an attempt to place vibration and control on a firm mathematical basis and connect the…

entanto, existem polímeros que não possuem massa molecular muito elevada. Esses polímeros são chamados oligômeros. Para os polímeros que realmente possuem alta massa molecular (da ordem de 103 a 106 g/mol), usa-se a expressão alto polímero (high polymer). O termo polímero vem do grego e quer dizer muitas partes, já o termo oligômero, também do grego, significa poucas partes. Os polímeros, diferentemente das substâncias químicas de baixa massa molecular, são produtos heterogêneos,…

fatorial. ABSTRACT The work involved the preparation, characterization and evaluation of conveying systems for sustained release 5-fluorouracil (5-FU), an antineoplastic agent. 5-FU was encapsulated in polymeric nanoparticles prepared from polymers of polylactic acid (PLA) and polyethylene glycol (PEG) by the technique of double emulsion-solvent evaporation and a factorial design was applied in order to obtain optimal formulations.These nanoparticles were characterized for…

apparatus is essential reading for all scientists and students in the physical, chemical, and biological sciences and engineering. Covering the physical principles governing the operation of the mechanical, optical and electronic parts of an instrument, the fourth edition contains new sections on detectors, low-temperature measurements, high-pressure apparatus, and updated engineering specifications. There are over 400 figures and tables to permit specification of the components of…
