The case of a teenager with guttate psoriasis secondary to trauma and upper airway infection is reported. Guttate psoriasis is the second most common psoriasis variant in pediatric age. Infection and trauma (leading to Koebner phenomenon) seem to be major triggers of the condition. The diagnosis is clinical. Most cases with no previous history of psoriasis spontaneously remit. Topical corticosteroids and vitami...
A linear sweep anodic stripping voltammetric method was developed for copper determination in commercial ethanol fuel samples by using a gold microelectrode. Under the optimized conditions, a linear range from 0.05 to 1.0 μM was obtained, with detection limit of 22 nM. The method was employed to determine copper ions in six commercial ethanol fuel samples and the results were compared with those obtained by FAA...
Object-oriented frameworks play an important role in current software engineering practice. Frameworks enable the development of several applications in a particular domain with high levels of reuse. However, although frameworks are a powerful means for software reuse, their reuse interface is typically difficult to learn, a problem which hinders their full potential. Different strategies can be used to overcom...
Neste trabalho, a redução eletroquímica do amebicida Teclozan (TEC) foi estudada sobre um eletrodo de carbono vítreo em meio de acetonitrila. Eletrólises com potencial controlado foram realizadas visando, tanto a determinação do número de elétrons envolvidos na redução do fármaco, quanto a identificação dos produtos eletrogerados, os quais foram isolados por extração líquido-líquido e caracterizados por 1H RMN....
In the context of framework-based development, Domain-Specic Modeling (DSM) is a paradigm that raises the level of abstraction of application engineering. Using a Domain-Specic Modeling Language (DSML), applications are described by domain concepts in a model from which the application code is generated. This paper presents an approach for automating the construction of a DSM infrastructure for an object-orient...
This technical report details the design, implementation, and experimental results of Webstore, a manager for web data. Webstore addresses the requirements of warehousing applications that need to incrementally store and maintain contents gathered from the web. In web warehouses the existence of duplicated contents is prevalent. Webstore provides an efficient elimination of duplicates mechanism based on the ana...
