1. Morphology of the megaspore Lagenoisporites magnus (Chi and Hills 1976) Candilier et al. (1982), from the Carboniferous (lower Mississippian: mid-upper Tournaisian) of Bolivia
Abstract: The morphology and structure of megaspores assigned to Lagenoisporites magnus from the Toregua Formation, Retama Group, mid-upper Tournaisian of Bolivia were studied. The analysis was performed with light, fluorescence and scanning electron microscopy. Megaspores were laterally compressed and presented a spherical body with a proximal gula, of the

3. Identification, expression and characterization of the recombinant Sol g 4.1 protein from the venom of the tropical fire ant Solenopsis geminata
Abstract Background: Fire ant venom is a complex mixture consisting of basic piperidine alkaloids, various biologically active peptides and protein components, including a variety of major allergenic proteins. Tropical fire ant Solenopsis geminata is an important stinging ant species that causes anaphylaxis and serious medical problems. Although the biologi

4. CT study of the performance of reciprocating and oscillatory motions in flattened root canal areas
Root canal preparation is an important step in endodontic treatment. The anatomical complexity of the middle third of the root compromises the effective cleaning of this area. Thus, advances have been made in instrumentation techniques and instruments for this purpose. The aim of this study was to evaluate the effects of three different instrumentation syste

5. Chemotaxonomy and flavonoid diversity of Salvia L.(Lamiaceae) in Iran
In this study, we evaluated the chemotaxonomic status and chemical diversity of Salvia L. species in Iran using leaf flavonoid profiles. From natural habitats in the country, we collected samples of 14 species of the genus: S. spinosa L.; S. macrosiphon Boiss.; S. reuterana Boiss.; S. sharifii Rech.f. & Esfand.; S. nemorosa L.; S. virgata Jacq.; S. syriaca L

6. Flow of a Williamson fluid over a stretching sheet
In the present article, we have examined the two dimensional flow of Williamson fluid model over a stretching sheet. The governing equations of pseudoplastic Williamson fluid are modelled and then simplified by using similarity transformations and boundary layer approach. The reduced equations are then solved analytically with the help of homotopy analysis m

7. Um estudo sobre o papel de medidas de similaridade em visualização de coleções de documentos / A study on the role of similarity measures in visual text analytics
Information visualization techniques, such as similarity based point placement, are used for generating of visual data representation that evidence some patterns. These techniques are sensitive to data quality, which depends of a very influential preprocessing step. This step involves cleaning the text and in some cases, detecting terms and their weights, as

8. Explorando conjuntos de dados volumétricos multidimensionais variantes no tempo usando projeções / Exploring time-varying multidimensional volumetric datasets using projections
The area of volume visualization encompasses a set of techniques used for representation, manipulation and display of data associated with a region of a volume, thus enabling the exploration and understanding of the interior of three-dimensional objects. However, some limitations are still encountered in this area. For example, the simultaneous exploration o

9. Caracterização bioquímica e biofísica da Celobiohidrolase II do fungo Trichoderma harzianum IOC3844 produzida por expressão homóloga / Biochemical and biophysical characterization of cellobiohydrolase II from Trichoderma harzianum IOC 3844 produced by homologous expression
The depletion of reserves, especially of refined oil , with increased energy demands and the urgent need to reduce the carbon emissions on the atmosphere, signals the necessity to search for new sources of energy renewable and clean. Concerns about global warming have led to an increased world interest in biofuels. The new concept of second generation biofue

11. Istar : um esquema estrela otimizado para Image Data Warehouses baseado em similaridade
A data warehousing environment supports the decision-making process through the investigation and analysis of data in an organized and agile way. However, the current data warehousing technologies do not allow that the decision-making processe be carried out based on images pictorial (intrinsic) features. This analysis can not be carried out in a conventiona

12. Treatment of time and dynamics in dta represented in metric spaces / Tratamento de tempo e dinamicidade em dados representados em espaços métricos
Nowadays, the Database Management Systems (DBMS) must be able to manage complex data, such as multimedia data, genetic sequences, temporal series, besides the traditional data. For queries on large collections of complex data, the similarity among elements is the most relevant concept, and it can be adequately expressed when data are represented in metric sp
