    Orientador : Ligia Maria Osorio SilvaDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de EconomiaResumo: O seguinte trabalho tem como objetivo estudiar, desde a perspectiva da História Econômica, o desenvolvimento da vitivinicultura no Estado de São Paulo, desde os finais do século XIX, até a primeira metade do século XX. Para tal fim, tem-se fixado o tempo de estudo entre 1880 e 1850. O trabalho, assim, está dividido em três partes: A primeira delas da uma idéia geral da vitivinicultura em São Paulo até 1880. A Segunda compreênde o período entre 1880 1 1930, e a final chega cronologicamente até o ano 1950. Dentro desta divisão cronológica, o estudo da vitivinicultura em São Paulo está focalizado considerando as seguintes fatos: O melhoramento das técnicas relativas à viticultura quanto à vinicultura. A tarefa desempenhada pela elite ilustrada paulista. A influência da imigração italiana na região. A tarefa realizada pelo Instituto Agronômico de Campinas nas melhoras agrárias em geral, e na vitivinicultura em particular. Além disso, como casos paradigmáticos do desenvolvimento na vitivinicultura em SãoPaulo, são estudadas em forma mais detalhada os casos dos municípios de São Roque e JundiaíMestradoMestre em História Econômic

    A new locality in Paraguay for the Black-tailed Marmoset, Mico melanurus (Geoffroy Saint-Hilaire, 1812) (Primates, Callitrichidae)

    Get PDF
    Mico melanurus is an endangered primate in Paraguay, with most Paraguayan records in the vicinity of Agua Dulce (Defensores del Chaco National Park). We report the first well-documented locality outside of the Agua Dulce/Linea 1 transect, representing the most northeastern record in Paraguay, as well as a new habitat for the species, transitional Pantanal-Cerrado. This note demonstrates the importance of monitoring areas which have been insufficiently studied for conservation purposes.

    "This paper is a preprint of a paper submitted to [journal] and is subject to Institution of Engineering and Technology Copyright. If accepted, the copy of record will be available at IET Digital Library"Drivers' road perception is an important human factor of comfort and safety on driving. Available sight distance of crest vertical curves superimposed on horizontal curves can be geometrically optimised by applying 3D coordination criteria. However, drivers might not perceive available sight distance improvements. Two approaches were used to investigate the effect of geometrical optimised design on perceived sharpness and visibility of isolated crest vertical curves overlapped with horizontal curves. A survey-based approach was used to evaluate subjective perception of 100 drivers. Three-dimensional renderings were displayed to subjects; who were asked to rank the curves by sharpness and sight distance. Moreover, 50 of those drivers previously participated on a driving simulation experiment involving the same curves, so objective driving data were collected too. Drivers' survey results indicate that driver's curve perception depends on the algebraic difference of grades while coordination of vertical and horizontal curves does not appear to affect this perception. On the other hand, the operating speeds on different curves were not statistically different from each other. Surprisingly, the operating speeds on a flat curve tended to be lower than on the vertical crest curves superimposed on the same horizontal curve. Likely causes are discussed in the paper.Moreno Chou, AT.; García García, A.; Camacho Torregrosa, FJ.; Llorca Garcia, C. (2013).

    HNRNPDL-related muscular dystrophy: expanding the clinical, morphological and MRI phenotypes

    Get PDF
    Autosomal dominant limb girdle muscular dystrophy D3 HNRNPDL-related is a rare dominant myopathy caused by mutations in HNRNPDL. Only three unrelated families have been described worldwide, a Brazilian and a Chinese carrying the mutation c.1132G>A p.(Asp378Asn), and one Uruguayan with the mutation c.1132G>C p. (Asp378His), both mutations occurring in the same codon. The present study enlarges the clinical, morphological and muscle MRI spectrum of AD-HNRNPDL-related myopathies demonstrating the significant particularities of the disease. We describe two new unrelated Argentinean families, carrying the previously reported c.1132G>C p.(Asp378His) HNRNPDL mutation. There was a wide phenotypic spectrum including oligo-symptomatic cases, pure limb girdle muscle involvement or distal lower limb muscle weakness. Scapular winging was the most common finding, observed in all patients. Muscle MRIs of the thigh, at different stages of the disease, showed particular involvement of adductor magnus and vastus besides a constant preservation of the rectus femoris and the adductor longus muscles, defining a novel MRI pattern. Muscle biopsy findings were characterized by the presence of numerous rimmed vacuoles, cytoplasmic bodies, and abundant autophagic material at the histochemistry and ultrastructural levels. HNRNPDL-related LGMD D3 results in a wide range of clinical phenotypes from the classic proximal form of LGMD to a more distal phenotype. Thigh MRI suggests a specific pattern. Codon 378 of HNRNPDL gene can be considered a mutation hotspot for HNRNPDL-related myopathy. Pathologically, the disease can be classified among the autophagic rimmed vacuolar myopathies as with the other multisystem proteinopathies.Peer reviewe
