CARACTERIZAÇÃO DE MICROPARTÍCULAS DE PLLA CONTENDO CURCUMINA PELA TÉCNICA DE EMULSIFICAÇÃO/EVAPORAÇÃO DE SOLVENTE / CHARACTERIZATION OF PLLA MICROPARTICLES CONTAINING CURCUMIN BY SOLVENT EMULSIFICATION/EVAPORATION TECHNIQUE

CARACTERIZAÇÃO DE UM NOVO COMPLEXO BIMETÁLICO DE Pd ( II ) CONTENDO

This article reports the synthesis and characterization of a new binuclear complex of palladium (II) containing the antibiotic oxytetracycline. The complex was characterized by the usual techniques of analysis. With respect to sites of coordination, the IR spectral data suggests the involvement the oxygen of the amide group and the oxygen of the neighbor hydroxyl group at ring A and to the carb...

Caracterização do comportamento de usuários e precificação de tráfego de internet de banda larga

Broadband user behavior characterization can lead to better understanding and identifying different classes of users, defined by user request patterns. This characterization could help broadband carriers capacity management and planning efforts. Different service request patterns require different service prices. Nevertheless, the main pricing scheme used by broadband ISPs (Internet Service Pro...

Effect of Preparation Conditions on Morphology, Drug Content and Release Profiles of Poly(hydroxybutyrate) Microparticles Containing Piroxicam

No presente estudo foram preparadas micropartículas de poli(hidroxibutirato) contendo piroxicam pela técnica de emulsão-evaporação do solvente. A influência de alguns parâmetros do processo sobre a eficiência de encapsulação do fármaco foi avaliada por meio de um planejamento fatorial do tipo 2. A eficiência de encapsulação do piroxicam variou de 5,5 a 89,8%. Micropartículas ocas e irregulares,...

Nueva técnica de fusión de clasificadores aplicada a la mejora de la segmentación de audio

This paper presents a new classifier fusion algorithm based on the confusion matrixes of the classifiers which are used to extract the corresponding precision and recall values. The only data needed to be able to apply this new fusion method are the classes or labels assigned by each of the classifiers as well as the reference classes in the development part of the database. The proposed algori...
