1. Effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved canals
AIM: To compare the effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved root canals. METHODS: Eighty acrylic-resin blocks with curved canals were instrumented with Gates-Glidden drills to simulate a ledge formation. Then, a K-File #10 was used for trying to surpass the deviation, and the blocks that permitted s

2. Desenvolvimento de uma metodologia numérica para estimativa de espessura de Ledge na produção de alumínio primário
Cada vez mais se busca um correto dimensionamento dos materiais refratários e uma correta escolha das variáveis operacionais dos reatores metalúrgicos. No caso da produção de alumínio primário, a competitividade do mercado exige alta vida útil da célula de redução eletrolítica, acompanhada de uma eficiência energética no processo, uma vez que a

3. ChangeLedge : change design and planning in networked systems based on reuse of knowledge and automation / ChangeLedge: projeto e planejamento de mudanças em sistemas de rede com base no reuso de conhecimento e automação
A gerência adequada de recursos e serviços de Tecnologia da Informação (TI) se tornou imperativa para o sucesso de organizações modernas. A Biblioteca de Infraestrutura de Tecnologia da Informação (Information Technology Infrastructure Library, ITIL) representa, nesse contexto, o framework mais popular para ajudar a alcançar esse fim. Para lidar com

4. Evaluation of the apical infiltration after root canal disruption and obturation
The aim of this study was to evaluate two root canal filling techniques used in teeth that had their apical foramen disrupted and compare the apical infiltration with an ideal clinical situation. Twenty-seven freshly extracted single-rooted teeth were selected and radiographed to confirm the existence of a single and straight root canal. The crowns were remo

5. Computação Evolutiva para a Construção de Regras de Conhecimento com Propriedades Específicas / Evolutionary Computing for Knowledge Rule Construction with Specific Properties
Most symbolic machine learning approaches use if-then know-ledge rules as the description language in which the learned knowledge is expressed. The aim of these learners is to find a set of classification rules that can be used to predict new instances that have not been seen by the learner before. However, these sorts of learners take into account the rule

6. Bibliotecas pedagogicas católicas: estratégias para construir uma civilização cristã e conformar o campo pedagógico através do impresso (1929-1938)
The object this research - Catholic Pedagogical Libraries - belongs to the cultural history knowledge and pedagogical practices. They are "immaterial" libraries, with no walls, constituted by press material inventory (books, magazines, newspaper material) produced, read, criticized, circulated by the members (subjects this research) two Catholic institutions

7. Conhecimento, administração e qualidade : a gestão da qualidade total como processo cognitivo
The objective of the present work is to show that total quality management (TQM) can be understood as a cognitive process, allowing its multidisciplinary analysis, in a coherent and integrated way. Knowledge has been selected as object of this study because it plays a fundamental role in all quality management techniques and, beyond that, is studied by vario

9. White lines in L-edge x-ray absorption spectra and their implications for anomalous diffraction studies of biological materials.
We have measured high-resolution x-ray absorption spectra of lanthanide (Ln) and heavy transition metal complexes that display prominent narrow absorption peaks near the L2 and L3 absorption edges. The anomalous scattering factors (f' and f"), which are mathematically related to the absorption cross section, have correspondingly sharp changes in their magnit

10. Localization of 5' and 3' ends of the ribosome-bound segment of template polynucleotides by immune electron microscopy.
Poly(U) with an average chain length of 40-70 nucleotides was modified at the 5'- or 3'-terminal residues with 2,4-dinitrophenyl derivatives. The modified poly(U) was used to form 30S.poly(U) or 70S.poly(U).Phe-tRNA complexes. Localization of the 5' and 3' ends of the template polynucleotide on the 30S subunit and the 70S ribosome was performed by immune ele

11. The structure of the cornified claw sheath in the domesticated cat (Felis catus): implications for the claw-shedding mechanism and the evolution of cornified digital end organs
The morphology of cornified structures is notoriously difficult to analyse because of the extreme range of hardness of their component tissues. Hence, a correlative approach using light microscopy, scanning electron microscopy, three-dimensional reconstructions based on x-ray computed tomography data, and graphic modeling was applied to study the morphology

12. Injurious effects of wool and grain dusts on alveolar epithelial cells and macrophages in vitro.
Epidemiological studies of workers in wool textile mills have shown a direct relation between the concentration of wool dust in the air and respiratory symptoms. Injurious effects of wool dust on the bronchial epithelium could be important in causing inflammation and irritation. A pulmonary epithelial cell line in vitro was therefore used to study the toxic
