The physical parameters of the device were tested with the aid of ionization chambers to measure rates of radiation, electrometer to measure rates of time, kV and doses, radiographic films and positioning devices. Finally, this work demonstrates the need and importance of quality control, which one ensures the proper use of x-ray machines, maintaining efficiency and at the same time it reduces the risks to the patient, to the dentist and to the general public

Desenvolvimento e controle de qualidade físico e microbiológico de emulsão O/A contendo óleo essencial de Melaleuca alternifolia

Sabe-se que na atualidade, é grande a preocupação da comunidade científica mundial, em relação à resistência microbiana frente às substâncias convencionais, utilizadas indiscriminadamente, por isso, é crescente a motivação da pesquisa básica na bioprospecção de novas substâncias, que apresentem atividade antimicrobiana e antifúngica e que possam ser uma alternativa segura e eficaz contra esses microorganismos no tratamento das doenças causadas por eles. As dermatofitoses, por exemplo, são processos infecciosos de pele, pêlo e unhas que acometem muitas pessoas, de todas as faixas etárias, no mundo todo, provocando as chamadas tinhas ou tineas, denominadas corporis, pedis, cruris, capitis, unguium(onicomicose) e outras (dependendo o local do corpo onde estão), causadas pelo dermatófito filamentoso, Trichophyton rubrum. Estudos envolvendo este patógeno são cada vez mais importantes, devido ao aparecimento de linhagens resistentes aos medicamentos antifúngicos disponíveis no mercado, e ao comportamento invasivo deste agente em pacientes com o sistema imune comprometido. Porém, somente a descoberta de novas drogas não é suficiente, é preciso desenvolver produtos eficazes e seguros, que possam veicular essas substâncias sem causar prejuízo ao paciente. Sendo assim, a proposta desse trabalho é desenvolver uma emulsão A/O, contendo óleo essencial de Melaleuca alternifolia (TTO), verificar sua estabilidade preliminar e caracterizá-la realizando o estudo reológico da formulação, determinar a concentração inibitória mínima (CIM) e a concentração fungicida mínima (CFM) do TTO e averiguar a atividade antifúngica in vitro da emulsão frente ao T. rubrum, agente patogênico ao qual se destina o uso do produto

Controle de qualidade e qualificação de fornecedores de matérias primas utilizadas em uma farmácia de manipulação

Este trabalho apresenta uma proposta de qualificação de fornecedores de matérias primas para uma farmácia na cidade de Araraquara, estado de São Paulo. A qualificação de fornecedores é um processo de extrema importância no que diz respeito ao produto acabado e, para que tenha qualidade, essa qualidade deve vir desde as matérias primas que o compõem. A RDC nº 67 de 8 de outubro de 2007 diz que as farmácias devem adquirir matérias primas apenas de fornecedores qualificados. Para o processo de qualificação, a mesma RDC diz que devem ser feitas auditorias e levantamentos de dados dos fornecedores, bem como o controle de qualidade das matérias primas fornecidas. Foram escolhidas quatro matérias primas utilizadas pela farmácia de três fornecedores diferentes. O processo começou com o envio de questionários avaliativos, onde cada fornecedor deveria colocar as informações solicitadas. O passo seguinte é o controle de qualidade das matérias primas. A partir dos dados dos questionários e dos resultados do controle de qualidade, acrescidos de outros fatores como prazo de entrega, compõe-se o Índice de Qualificação do Fornecedor (IQF), que é como uma “nota” que o fornecedor recebe e, através desse índice, pode ser DESQUALIFICADO, QUALIFICADO ou ainda CERTIFICADO. A certificação ocorre após a auditoria do estabelecimento do fornecedor e também entra na composição do IQF. Após o processo de qualificação dos três fornecedores, foi elaborado um Procedimento Operacional Padrão (POP) com todas as etapas que devem ser feitas para a qualificação...

Modelagem computacional das túnicas cardíacas para processamento e controle de qualidade

This paper considers a study of the anatomical features of the cardiac system and a three-dimensional model of the different tunics that comprise the heart wall, for processing and quality control of radiological images. The structures are built by the layer overlapping method, where a layer can be understood as a slice of the three-dimensional object. The pericardium, myocardium and endocardium were represented with three-dimensional cylinders and hexagons. The spatial arrangement of the cardiac system is determined by an background image of a real model, which values are defined according to the shape of the region and on the anatomical patients characteristics. The results are significant, considering the anatomical structures details, as well as the representation of the thicknesses of the regions of the heart wall. The validation of the anatomical model was accomplished through comparisons with dimensions obtained from a real model and allows verifying that the model is appropriate. The degree of representation will allow the verification of the influence of radiological parameters, morphometric peculiarities and stage of the diseases on the quality of the images, as well as on the performance of the Computer-Aided Diagnosis (CAD).
