1. In vitro Monitoring of Macro and Microelements in Multimineral Preparations across Dissolution Profiles by Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES)
In this study, inductively coupled plasma optical emission spectrometry (ICP OES) was used for multi-element analysis in five multimineral preparations from a dissolution test, in accordance with the United States Pharmacopeia (USP 34 method): apparatus 1, 75 rpm and 900 mL of 0.1 mol L-1 HCl. Element releases in all samples (minimum-maximum in %) were: Ca (

2. Abordagens para aprendizado semissupervisionado multirrótulo e hierárquico / Multi-label and hierarchical semi-supervised learning approaches
In machine learning, the task of classification consists on creating computational models that are able to automatically identify the class of objects belonging to a predefined domain from a set of examples whose class is known a priori. There are some classification scenarios in which each object can be associated to more than one class at the same time. Mo

3. O uso de redes neurais auto-organizÃveis na anÃlise da transferÃncia de conhecimentos prosÃdico em aprendizes brasileirios de lÃngua inglesa / The use of self-organizing artificial neural networks for the analysis of prosodic knowledge in Brazilian learner of English
The objective of this dissertation was to investigate how the prosodic knowledge is organized in an early stage of L2 acquisition in Brazilian learners of English with the help of a connectionist neural network. The approach proposed in this research is first, to quantify the utterances of L2 learners in the form of LPC coefficients and other linguistic/phon

4. Effects of galantamine on attention and memory in Alzheimer's disease measured by computerized neuropsychological tests: results of the Brazilian Multi-Center Galantamine Study (GAL-BRA-01)
Objective: To investigate the effects of galantamine on the performance of patients with mild to moderate Alzheimer’s disease (AD) in a computerized neuropsychological test battery (CNTB). Method:Thirty-three patients with probable AD were treated with galantamine for three months and evaluated in a prospective, open-label, multi-center study. The CNTB and

5. Classificação multi-rótulo hierárquica de documentos textuais
The amount of information stored in text databases is steadily increasing. As such, demand for automated techniques to organize this data also continues to grow. In this context, academic and industry research has been focused on the study of automatic text classification. Most work on text classification studies the development of techniques in which there

6. Algebraic formulation for modeling hop-by-hop multi-constrained routing algorithms. / Formulação algébrica para a modelagem de algoritmos de roteamento multi-restritivo hop-by-hop.
This work presents a new mathematical structure for paths algebra that allows the convergence analysis of hop-by-hop multi-constrained routing algorithms and, under the traffic engineering and quality of service perspectives in the Generalized Multiprotocol Label Switching (GMPLS) architecture, trustily ensures the aggregation of new routing metrics in a con

7. Referências críticas na psicologia e novas histórias de loucura: psicologia sócio-histórica e loucura: uma reflexão
The purpose of this work is to analyze critically the basis on which a group of readings and practice about the madness was built, which ended up by leading to its inscription under,the group of mental diseases and also the development of disciplinary and violent approaches considered to be treatments. Such critical analysis is based on the references of Soc

8. Bent Fatty Acid Chains in Lecithin Bilayers
An analysis of the paramagnetic resonance spectra of a number of phospholipid spin labels in multi-lamellar arrays of lecithin bilayers has been carried out in terms of a distribution of label orientations, and the amplitude and time dependence of high-frequency random motions about these orientations. This analysis indicates that there is a long-lived (>10-

9. Nucleic acid capture assay, a new method for direct quantitation of nucleic acids
Technologies allowing direct detection of specific RNA/DNA sequences occasionally serve as an alternative to amplification methods for gene expression studies. In these direct methods the hybridization of probes takes place in complex mixtures, thus specificity and sensitivity still limit the use of current technologies. To address these challenges, we devel
