Emprego de planejamento experimental no desenvolvimento de métodos cromatográficos na indústria farmacêutica
(Universidade Federal de São Carlos, 2012-11-01) Miglioranza, Bruna; Carneiro, Renato Lajarim; https://lattes.cnpq.br/8065852319463976; https://lattes.cnpq.br/0163273491112677
The aim of this study was to use experimental design techniques during the development and validation of high performance liquid chromatography (HPLC) methods for analysis of drugs in the pharmaceutical industry in order to demonstrate its applicability and benefits of its use. A multivariate assessment of the robustness of an assay method for vitamins of the B complex enabled the visualization of interactions between variables, which would not be possible through the univariate approach. A mixture design was performed for determining the extraction solvents of sesquiterpene lactones in pharmaceutical formulation containing arnica tincture. The mixture of solvents selected through the study allowed desirable extraction of compounds of interest from the sample, which was confirmed through the validation of the methodology. Finally, we conducted an exploratory planning on an analytical methodology for the determination of latanoprost, timolol maleate, preservatives and degradation product in eye drops. The design allowed the reduction of chromatographic run time and waste generation by about 44%.
Guibuilder multimodal : um framework para a geração de interfaces multimodais com o apoio de interaction design patterns
(Universidade Federal de São Carlos, 2012-11-01) Fragoso, Ygara Lúcia Souza Melo; Pizzolato, Ednaldo Brigante; https://lattes.cnpq.br/2821982735490884; https://lattes.cnpq.br/9707510340233192
The interaction between humans and the computers has improved substantially during time through the evolution of interfaces of interaction. The possibility of users to interact with machines through several modalities of communication, and in a natural way, can increase the level of interest from the user and ensure the success of the application. However, the literature of the area of multimodality has shown that developing such interfaces is not a simple task, mainly for non-experienced or recently graduated professionals, since each designer’s modality of interaction has its complexity in technical terms, as acquisition and adaptation with new tools, languages, possible actions and etc. Moreover it is necessary to verify which modalities (voice, touch and gestures) can be used in the application, how to combine these modalities in a way that the stronger point of one completes the weak point of the other and vice versa, and also knowing in what context the final user will be involved. The GuiBuilder Multimodal was developed aiming to try providing the basic needs in implementing an interface that uses voice, touch and gesture. The framework promotes an interface development through the WYSIWYG (What You See Is What You Get) model, where the designer just sets some parameters so the component is multimodal. During the interface creation phase, agents supervise what the designer does and supply support, clues, with design patterns that might be divided in categories such as: multimodality, interaction with the user and components.
