13. Effect of temperature, concentration, polarity of the medium and surfactant on the rheology and morphology of emulsions with oil from mature fields. / Efeito da temperatura, concentração, polaridade do meio e de surfactante sobre a reologia e morfologia de emulsões com petróleo oriundo de campos maduros.
Durante a extração e transporte do petróleo proveniente de campos maduros existem dois grandes problemas que são: a formação de depósitos orgânicos e a presença de água emulsificada. Estes causam obstrução total ou parcial da secção transversal das tubulações e um acréscimo considerável na viscosidade do óleo, gerando por várias vezes lon

14. Comics are imagetic information attached to universitary teaching / As histórias em quadrinhos como informação imagética integrada ao ensino universitário
Comics are indispensable, expressive visual objects for communication and information because they have followed the cultural process of humanity since its beginning. Comics also exist because the technology made them possible. The scientificparadigm has changes from classic Cartesians to quantum, transforming the interaction between man and reality, from a

15. The New Institutional Economics and the Onshore Oil and Natural Gas Exploration and Production Activities in Mature Fields in Brazil. / "A nova economia institucional e as atividades de exploração e produção Onshore de petroléo e gás natural em campos maduros no Brasil"
By Adopting the New Institutional Economics (NIE), and the theory of Transaction Cost Economics (TCE), this work discuss about the Brazilian institutional environment for oil and natural gas exploration and production (E&P), the regulation and main features. This study discusses the specificities related to the development of onshore activities on mature and

16. Mature and Marginal Field - Definition for Regulatory Purpose / Campos maduros e campos marginais - definições para efeitos regulatórios
Não existem definições objetivas de campos maduros e campos marginais na indústria do petróleo. No atual cenário regulatório brasileiro estas definições se fazem necessárias, tendo em vista que as atividades nesses campos devem ser incrementadas seja por uma conjuntura econômica mais favorável, seja por meio de incentivos fiscais e regulatórios,

17. ESTIMATIVA PROBABILÍSTICA DE RESERVAS RECUPERÁVEIS DE PETRÓLEO: MÉTODOS E APLICAÇÃO / PROBABILISTIC ESTIMATION OF RECOVERABLE OIL RESERVE: METHODS AND APPLICATION
This dissertation is intended to present and apply the probabilistic methods to estimate the recoverable reserves of mature oil fields (fields in the decline phase), from the historical production data (production rate and time). Initially, a bibliographical review is made and the methods of adjustment of the decline curve and probabilistic estimation of the

18. Distribution of Bacteria within the Tissue of Healthy Tomatoes1
Bacteria have been shown to be present in fresh normal tomatoes. The frequency of their presence differed widely between different fields. Bacterial populations within the tomatoes showed a distinct gradient, being largest in the connective tissue at the stem end and decreasing through the central core towards the peripheral and distal tissue. Application of

19. Organization and post-natal development of the monkey's lateral geniculate nucleus.
We have studied the properties of neurones in the lateral geniculate nucleus (l.g.n.) of Old World monkeys, both in mature animals and throughout post-natal development. Cells were classified as X (linear) or Y (non-linear) on the basis of their responses to contrast-reversing achromatic gratings ('null position test'). In older animals virtually all parvoce

20. Stimulus selectivity and state dependence of activity in inferior temporal cortex of infant monkeys.
Inferior temporal cortex is necessary for visual object recognition in adult primates but is less critical in infants. Nonetheless, in macaques as young as 6 weeks old, inferior temporal neurons showed adult-like visual response properties, including form selectivity and bilateral receptive fields, indicating that extended maturation and visual experience ma

21. Usher Syndrome Type III: Revised Genomic Structure of the USH3 Gene and Identification of Novel Mutations
Usher syndrome type III is an autosomal recessive disorder characterized by progressive sensorineural hearing loss, vestibular dysfunction, and retinitis pigmentosa. The disease gene was localized to 3q25 and recently was identified by positional cloning. In the present study, we have revised the structure of the USH3 gene, including a new translation start

22. Toward Rigorous Comprehension of Biological Complexity: Modeling, Execution, and Visualization of Thymic T-Cell Maturation
One of the problems biologists face is a data set too large to comprehend in full. Experimenters generate data at an ever-growing pace, each from their own niche of interest. Current theories are each able, at best, to capture and model only a small part of the data. We aim to develop a general approach to modeling that will help broaden biological understan

23. Responsiveness of cat area 17 after monocular inactivation: limitation of topographic plasticity in adult cortex.
1. Recordings were made from neurones in the splenial sulcus of normal adult cats and adult cats which had one eye inactivated by enucleation or photocoagulation of the optic disc. Two visually responsive regions were observed, corresponding to the peripheral representation of visual area 1 (V1) and the splenial visual area. In normal animals, responses to t
