26. EVOLUÇÃO DA LEGISLAÇÃO E DAS TÉCNICAS ANALÍTICAS APLICADAS A ESTUDOS DE ESTABILIDADE DE INSUMOS E PRODUTOS FARMACÊUTICOS
Stability is an important parameter to evaluate the quality, safety and efficacy of drug substances and pharmaceutical products. The stability studies aim to determine the ability of a formulation to maintain its specifications, in order to establish shelf life and recommended storage conditions. Despite the extensive relevance, until the 1980’s the stabil

30. Stability evaluation of juçara, banana and strawberry pasteurized smoothie during storage
Abstract The objective of this work was to evaluate the effect of storage time and temperature on main characteristics of a juçara (20%), banana (40%) and strawberry (40%) pasteurized smoothie. The pasteurized smoothie was stored at 7 °C and 25 °C for 90 days. At both temperatures there was degradation of the smoothie anthocyanins, which, as expected, was

34. Cachaça production from sugarcane infested by Diatrea saccharalis
Abstract Cachaça is a highly consumed Brazilian spirit, which still needs studies on its agroindustrial processing. We can highlight the effects of infestation of pest insects in the sugarcane, and the chemical-physically characteristics of the drink. So, the aim of the study was to evaluate the consequences of the infestation of the sugarcane borer (Diatre

36. Prevenção da indisciplina num agrupamento de escolas de Portugal
Resumo A indisciplina revela-se um conceito de difícil definição que surge invariavelmente associado ao contexto escolar. A definição de indisciplina assenta numa oposição clara ao conceito de disciplina e assume-se como uma quebra da ordem, de regras e de normas, prejudicando a prossecução e/ou alcance de um objetivo. Este estudo destina-se a anali
