Modelo para auxiliar a detecção de inteligências múltiplas

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Ciência da Computação.O objetivo deste trabalho é propor um modelo , baseado em computador, para auxiliar na detecção precoce das inteligências múltiplas. Nessa abordagem buscar-se-á respeitar incorporar os princípios da teoria das inteligências múltiplas. Em função disto, centrou-se na implantação de um projeto de inteligências múltiplas num colégio da rede particular de ensino, para verificar a prática escolar com base nessa nova proposta de ensino, e também na criação de um software, para ser utilizado por pedagogos, psicopedagogos e psicólogos, com jogos e atividade educativas, como uma ferramenta para agilizar o processo de detecção das inteligências múltiplas em criança de seis a dez anos de idade. Com a realização desta pesquisa uma das principais conclusões obtidas é que a informática e os avanços tecnológicos podem se tornar boas ferramentas para auxiliar e agilizar o processo de detecção das inteligências múltiplas, mas não podem ser considerados um fim e sim um caminho . Outra constatação, é que o software criado, não tem valia se não for utilizado por um profissional competente, capaz de identificar e interpretar constantemente, as mudanças de comportamento de cada criança, avaliando-a num todo

Quantification of fatty acids in salmon fillets conserved by different methods

 Lipid contents and the composition of fatty acids of fillets from Chilean salmon (Salmo salar) were determined under different conservation methods: fresh salmon, frozen salmon, water-conserved canned salmon and frozen salmon in long-term storage. Fatty acid contents were determined by gas chromatography. The fillets had high lipid levels, ranging between 9.71 and 12.86%. All samples presented high levels of monounsaturated fatty acids, between 363.69 and 425.30 mg g-1 of total lipids, followed by polyunsaturated fatty acids (294.46 - 342.45 mg g-1 of total lipids) and saturated fatty acids (203.32 - 223.17 mg g-1 of total lipids). Although samples revealed different lipid contents, all proved to be great sources of omega-3 fatty acids, regardless of the manner of conservation.

Optimization of a New Methodology for Determination of Total Phenolic Content in Rice Employing Fast Blue BB and QUENCHER Procedure

Response surface methodology was used to optimize the total phenolic content (TPC) result in white rice, using a new methodology that employed Fast Blue BB (FBBB) reagent, which reacts more specifically with phenolic compounds, along with direct QUENCHER procedure. This is the first time in which such conciliation between FBBB reagent and QUENCHER was done. The obtained model allowed to evaluate how the factors influenced the method linearity (R2), improving the choice of the optimal system condition. Furthermore, the similarity between experimental results and values generated by the model indicated the method validity within the studied region. Thus, the optimal condition determined in the present work was 30 min reaction time, 0.17 mL FBBB reagent and use of 5% NaOH as the catalyst for the reaction. This optimized condition suggested that the combination of the method, which used FBBB reagent and the direct QUENCHER procedure, was rapid and effective, yielding high TPC values (1488.73 mg of gallic acid equivalent per 100 g)

Opleiding als sociale scheidslijn. Een nieuw perspectief op een oude kloof

Over opleiding als sociale scheidslijn is al veel gezegd en geschreven. Maar een gedegen analyse waarin systematisch is onderzocht of de kloof tussen hogeren lageropgeleiden werkelijk is toegenomen in de Nederlandse samenleving, ontbrak nog. De auteurs laten zien dat er een aanzienlijke kloof is tussen hoger- en lageropgeleiden op het vlak van de arbeidsmarkt, attitudes, politieke participatie en gezondheid. Ook wat betreft vrijwilligerswerk, de huwelijksmarkt en het vermijden van sociale daling is opleidingsniveau een belangrijke factor. Maar in tegenstelling tot wat vaak wordt beweerd, neemt het belang van opleiding voor maatschappelijke kansen niet toe. Opleiding is dus niet als de nieuwe sociale scheidslijn te bestempelen. Ze was dat al en is het nog steeds. Het is bovendien niet waarschijnlijk dat de opleidingskloof alsnog sterk aan belang zal winnen. Daarmee biedt dit boek voor wetenschappers, beleidsmakers en anderen die zich met het onderwijs bezighouden, een nieuw perspectief op een oude kloof

Efficiencies of Acid and Base-Catalyzed Methylation of Vegetable Oils by Ambient Mass Spectrometry

The fatty acids (FA) profile is an important parameter for quality control and typification for foods in general. These profiles work as a sort of "fingerprint", and may be useful to monitor frauds and deterioration of diverse types of foods. For vegetable oils, the FA profile is commonly determined after hydrolysis, methylation and gas chromatography (GC) analysis. In this work, the acid and base-catalyzed soybean oil methylation methods was monitored via GC-FID and also by ambient sonic-spray ionization mass spectrometry (EASI-MS). The base-catalyzed method is much superior regarding other esterification assays, because it is cheaper, less toxic, no oxidation products are formed and its reaction yield is greater (95.66% m/m against 92.86% and 94.51% from acid-catalyzed methylation methods, respectively)

Evaluation of antioxidant potential of Brazilian rice cultivars

This study quantified the fatty acids and evaluated the proximate composition, antioxidant activity (using the Quencher procedure), and total phenolic compound concentrations in Brazilian rice cultivars. The cultivars studied showed high amounts of unsaturated fatty acids, such as linoleic and oleic acid. The ratios of polyunsaturated and saturated fatty acids obtained were high. Regarding the antioxidant activity, the best results were found using the ABTS method and the worst in the DPPH assay. The results of the DPPH and FRAP assays showed the highest correlation. The antioxidant capacity results obtained were also much higher than those reported for other varieties worldwide. Therefore, the Quencher procedure is highly suitable for application in cereals such as rice, especially when combined with the ABTS radical capture method
