A capitania de São José do Piauhy na racionalidade espacial Pombalina (1750-1777)

Em meio às intervenções políticas, econômicas e administrativas realizadas no Brasil a partir de 1750, é possível observar como se deram as tentativas de organização da capitania de São José do Piauhy e até mesmo o seu reconhecimento como importante área pecuarista da colônia. Neste trabalho, realizou-se um recorte espacial priorizando a região em que a apropriação territorial teria se dado de forma mais diversa em tal capitania, pois além dos procedimentos de aquisição de sesmarias, existiram ainda os processos de herança e confisco. Sobre estes últimos, os mesmos incidiram sobre as fazendas que pertenceram ao sertanista baiano Domingos Afonso Mafrense, e que após serem deixadas de herança para os religiosos da Companhia de Jesus (1711), foram confiscadas pela Coroa Portuguesa (1759). Isso aconteceu em meio ao planejamento e execução de medidas governamentais que atingiram todos os domínios portugueses durante esse período, a chamada Política Pombalina. Tais intervenções administrativas, por sua vez, puderam ser analisadas tomando-se como referência a confecção da primeira representação cartográfica destinada a tal capitania, o Mappa Geográfico da Capitania do Piauhy, produzido pelo engenheiro italiano Henrique Antônio Galúcio. Deste modo, considerando-se as particularidades da política portuguesa destinada ao interior do Brasil, em meados do séc. XVIII, com destaque para as medidas incidentes sobre os modos de vida indígena e rural, observou-se a tentativa de implantar-se uma nova forma de organização espacial, a partir de modos e instalações urbanas. Neste contexto, São José do Piauhy passa a ser alvo de intensas investidas enquanto área oficialmente pertencente ao Estado do Grão-Pará e Maranhão

Influência da Dureza dos Discos Abrasivos no Corte de Materiais Dúcteis

O corte de materiais por disco abrasivo é um dos processos que apresentam as melhores características de economia, eficiência e rapidez sendo muito utilizado no meio industrial. Fatores como porcentagens e homogeneidade da mistura dos componentes, tamanho, forma (abrasividade), tenacidade e dureza dos grãos abrasivos, tipos de ligantes e de abrasivos, velocidade de corte e velocidade de mergulho influenciam na segurança, no desempenho e comportamento da operação. Este trabalho apresenta um estudo sobre a influência da dureza dos discos abrasivos no desempenho do processo de corte em operações do tipo remoção a seco. O aumento da dureza dos discos propiciou um aumento da força tangencial de corte e da relação G, devido à mais forte ligação entre o grão e o ligante no compósito. Os resultados mostram que a dureza dos discos abrasivos afeta a economia, pois influencia na vida útil dos discos abrasivos em termos de números de cortes proporcionados; a produtividade, pois está relacionada com o número de trocas de discos desgastados; os esforços necessários para a operação, pois estão relacionados com as forças tangenciais de corte.

Avaliação do desempenho de corte de diferentes grãos adiamantados

Por meio de um trabalho multidisciplinar entre Engenheiros e Dentistas, foram estudados oito diferentes tipos de grãos abrasivos de diamantes para a fabricação de pontas adiamantadas e/ou rebolos de pequeno diâmetro. Verificou-se qual o grão mais adequado para ser empregado nas pontas, as quais são utilizadas em equipamentos que possuem um pequeno torque disponível. Uma metodologia de experimentação para avaliação da capacidade de corte destas ferramentas foi desenvolvida, utilizando-se o vidro como material a ser desgastado. Como resultados, observou-se que a estrutura e a friabilidade do grão de diamante afetam diretamente a capacidade de corte das pontas adiamantadas. Desta forma, o melhor tipo de diamante foi aquele que apresentou, ao mesmo tempo, as melhores condições de remoção de material e o menor preço.

Influência da salinidade e temperatura da água nas respotas comportamental e fisiológica de camarões marinhos Litopenaeus vannamei(BOONE 1931)

The shrimp Litopenaeus vannamei has been grown in highly variable environments, especially in relation to salinity and water temperature. The adjustment to such conditions mainly involves changes in behavior, physiology, particularly in the immune response. This may consequently reduce the welfare of these animals. Despite the widespread farming of the species, little is known about their behavioral and physiological responses under stressful conditions. Thus, the objective of this study was to assess the influence of different salinities and temperatures in the behavior of the marine shrimp L. vannamei, and its relation to the total hemocytes count. In the laboratory, juvenile shrimp were kept in glass aquaria with a closed water recirculation system, continuous aeration and filtration, and under a 12:12 h light/dark cycle. Behavioral observations occurred 1, 4, 7 and 10 h after the start of each phase (light or dark). To assess the influence of salinity, shrimp were first acclimated and then observed at 2, 30 or 50 ppm salinity water, while temperatures tested were 18, 28 and 33 ° C. At the end of each experiment (30 days), shrimp hemolymph was collected for subsequent total hemocytes count (THC), a parameter used to assess stress. In general, feeding behavior was modified under lower salinity and temperature, with reduced values in feeding, exploration and digestive tract filling. Inactivity and burrowing were prevalent under extreme conditions water salinity and temperature, respectively: 2 and 50 ppm and 18 and 33 ° C; crawling was also less frequent under these conditions. In regards to light/dark cycle, shrimp were more active during the dark phase (crawling and swimming), while burrowing was higher during the light phase, regardless of salinity or temperature of the water. Inactivity behavior did not vary according to the light/dark cycle. Moreover, the total hemocytes count (THC) was reduced under 2 and 50 ppm salinity and 18 ° C temperature. Farming of L. vannamei under extremely low or high salinities and low temperatures is harmful. This suggests the species must be cultivated in salinities closer to those of the sea as well as at high temperatures, which seems to be ideal for a management focused on animal welfare, therefore, producing healthier shrimp

Influência da densidade de estocagem sobre o crescimento, ciclo de muda e o comportamento em juvenis do camarão marinho Litopenaeus vannamei

One of the factors that may interfere with the cultivation of Litopenaeus vannamei is the population density. This study aimed to assess the effect of density on growth, mortality, physical integrity and behavior of shrimp. The study was divided into two stages. At first, the shrimp were placed in tanks at densities of 50, 75 and 100 shrimp m-2. The animals were monitored in relation to the degree of proventricular filling, the stage of the molt cycle and physical integrity three times a week and in relation to the weight and length once a week. Mortality, growth and proventricular filling were not influenced by the density; frequency of records in specific stages of the molt cycle varied according to the density. The lower proportion of broken appendages and higher frequency of necrotic lesions occurred in lower density. The second stage of the research, conducted in aquaria, was divided into two parts. The first described social or feeding behavioral categories: slow displacement by contact, slow displacement by approximation, abrupt displacement by contact, abrupt displacement by approximation, reactivity, cannibalism, occupying the tray, get feed in the tray and get feed outside the tray. In the second part, these and other behavioral categories, described in the literature, were recorded in densities of 50, 75 and 100 shrimp m-2. Mortality was more frequent in higher density. The frequency of most behaviors mentioned above was very low, not differing between densities or being too low to determine differences between them. The behavioral profile of animals in different densities was, in general, very similar, with no difference in exploration, digging and cleaning between the densities. Even so, inactivity, feeding, crawling, burrowing, swimming, and proximity between animals were influenced by the density. These results suggest that some behaviors suffer greater interference from population density. However, the density may not have a broader influence on the animals when other factors, such as physico-chemical parameters of water and feed offering, are adequate

Influência do tamanho e da forma da semente de milho sobre o desenvolvimento da planta e a produtividade de grãos

Due to the small and the round seeds represent a rather high proportion of an ear, this experiment viewed to study the effects of those factors on seed germinative performance in the field as well as on the plant traits related to grain yield. Six treatment combinations replicated five times were sown in Votuporanga/SP on 08/22/2008. Flat shaped (C) and round shaped (R) seeds were made to go through flat round and oblong hole screens which resulted in the following treatments: 1. C1: seeds remaining on the top of a 23/64 '' round hole screen, 2. C2G: 21/64 '', 3. C3M: 17/64 '' or 16/64 '', 4. R2GM: medium length seeds remaining on the top of 13 x 3/4 '' oblong hole screen, 5. R3M: medium length seeds remaining on a 12 x 3/4 '' (from 1 to 2 mm bigger than R3), and 6. R3: 12 x 3/4 ''. The soil of the experimental area was submitted to a no-till cultivation system and the rows were set 0.6 m apart from one another. Fifteen days after emergence (DAE), the plants were thinned to a population of 66,000 plants/ha. Harvest took place 115 DAE and the mean yield was of 12,498 kg ha(-1). Based on the results it was concluded that only the initial growth of the plants is significantly affected by seed size. Plant traits such as plant height, ear insertion height, culm diameter, number of grains per year, grain weight and size as well as grain yield evaluated 40 or more DAE are not significantly affected by seed size or seed shape.

Um estudo algorítmico de problemas logísticos na indústria de petróleo e gás natural

This work consists on the study of two important problems arising from the operations of petroleum and natural gas industries. The first problem the pipe dimensioning problem on constrained gas distribution networks consists in finding the least cost combination of diameters from a discrete set of commercially available ones for the pipes of a given gas network, such that it respects minimum pressure requirements at each demand node and upstream pipe conditions. On its turn, the second problem the piston pump unit routing problem comes from the need of defining the piston pump unit routes for visiting a number of non-emergent wells in on-shore fields, i.e., wells which don t have enough pressure to make the oil emerge to surface. The periodic version of this problem takes into account the wells re-filling equation to provide a more accurate planning in the long term. Besides the mathematical formulation of both problems, an exact algorithm and a taboo search were developed for the solution of the first problem and a theoretical limit and a ProtoGene transgenetic algorithm were developed for the solution of the second problem. The main concepts of the metaheuristics are presented along with the details of their application to the cited problems. The obtained results for both applications are promising when compared to theoretical limits and alternate solutions, either relative to the quality of the solutions or to associated running time

Insuficiência cardíaca com fração de ejeção normal

A insuficiência cardíaca com fração de ejeção normal (ICFEN) é uma síndrome complexa que vem sendo largamente estudada, desde a última década. É causada por disfunção ventricular diastólica evidenciada por métodos complementares, como estudo hemodinâmico ou ecocardiograma, na presença de fração de ejeção preservada. Acomete preferencialmente indivíduos mais idosos e com comorbidades, como hipertensão arterial sistêmica, insuficiência coronariana e obesidade. Os mecanismos fisiopatológicos são complexos e multifatoriais, envolvendo a rigidez passiva do miocárdio, a geometria ventricular, a força de contenção do pericárdio e a interação entre os ventrículos. Os objetivos principais do tratamento são reduzir a congestão venosa pulmonar, a frequência cardíaca e controlar as comorbidades. Ainda não há evidências fortes de que o uso de medicações específicas, como inibidores de enzima de conversão ou betabloqueadores, interfiram na mortalidade. Os fatores de pior prognóstico incluem a idade avançada, presença de disfunção renal, diabete, classe funcional III e IV (NYHA) e estágio avançado de disfunção diastólica, com padrão restritivo ao enchimento ventricular. Outro aspecto que vem ganhando espaço na literatura é o questionamento do papel da disfunção sistólica nos quadros de ICFEN. Todos esses aspectos são abordados detalhadamente na presente revisão.

Macrofauna de ambientes não consolidados adjacentes à recifes da área de proteção ambiental dos recifes de corais Rio Grande do Norte, Brasil

This study aimed to characterize, for the first time, the benthic invertebrates that inhabit the region of soft bottoms adjacent to the APARC reefs in order to situate them as an important component of infralittoral coastal areas of Northeast Brazil. Soft bottoms areas of APARC corresponds to infralittoral zones vegetated by seagrass Halodule wrightii and unvegetated infralittoral zones, both subjected to substantial hydrodynamic stress. Through scuba diving, biological and sedimentary samples of both habitats were analyzed, with a cylindrical sampler. We identified 6160 individuals belonging to 16 groups and 224 species. The most abundant macrofaunal group was Polychaeta (43%), followed by Mollusca (25%) and Crustacea (14%), what was expected for these environments. In the first chapter, regarding vegetated areas, we tested three hypotheses: the existence of differences in the faunal structure associated with H. wrightii banks submitted to different hydrodynamic conditions; the occurrence of minor temporal variations on the associated macrofauna of banks protected from hydrodynamic stress; and if the diversity of macrofauna is affected by both benthophagous predators and H. wrightii biomass. It was observed that macrofauna associated at the Exposed bank showed differences in structure when comparing the Protected bank, the granulometry of the sediments, that co-varies with the hydrodynamism, was the cause of these variations. The results also pointed to a lower temporal variation in the macrofaunal structure on the Protected bank and a negative relation between macrofaunal and benthophagous fish abundance. At the Exposed bank, a greater faunal diversity was observed, probably due to the higher seagrass biomass. The second chapter compares the vegetated and non-vegetated areas in order to test the hypothesis that due to greater seasonal stability in tropical environments, seagrass structure would act to distinguish the vegetated and non-vegetated areas macrofauna, over time. It was also expected that depositivores were the most representative invertebrates on non-vegetated environments, on the assumption that the seagrass bank would work as a source of debris to adjacent areas, enriching them. Considering all sampling periods, the total macrofauna abundance and diversity were higher in vegetated areas, when compared to non-vegetated ones. Seasonally, the structural complexity provided by Halodule differentiated more clearly the fauna from vegetated and non-vegetated areas, but only at the climatic extremes, i.e. Dry season (extreme climatic stability, with low hydronamism variation) and Rainy season (great hydrodynamism variation and probably vegetated bank burial). Furthermore, the high organic matter levels measured in the sandy banks coincided with an outstanding trophic importance of deposit feeders, proving the debris-carrying hypothesis. The last chapter focused on the non-vegetated areas, where we tested that the hypothesis infaunal halo in tropical reefs depending on local granulometry. In this context, we also tested the hypothesis that benthophagous fish predation would have an effect on the low abundance of macrofaunal groups due to the high hydrographic stress, thus allowing other predatory groups to have greater importance in these environments. Proving the hypothesis, no spatial variation, both on abundance families neither on community structure, occur along distance of the edge reefs. However, we found that complex combinations of physical factors (grain size and organic matter levels originated from local hydronamic conditions) covary with the distance from the reefs and has stronger influence on macrofauna than considered biological factors, such as predation by benthophagous fishes. Based on the main results, this study shows that unconsolidated areas around APARC reefs are noteworthy from an ecological and conservational point of view, as evidenced by the biota-environment and organismal relations, never before described for these areas

Limites e evolução geodinâmica do Sistema Jaguaribeano, Província Borborema, Nordeste do Brasil

The studied area is geologically located in the Northern Domain of the Borborema Province (Northeast Brazil), limited to the south by the Patos shear zone. Terranes of the Jaguaribeano system are dominant, flanked by the Piranhas (E and S sides) and Central Ceará (NE side) terranes. Its basement comprises gneiss -migmatite terrains of Paleoproterozoic to Archean age (2.6 to 1.9 Ga old), overprinted by neoproterozoic to cambrian tectonotherma l events. Narrow supracrustal belts ( schist belts) display a 1.6 to 1.8 Ga age, as shown by whole - rock Rb-Sr and zircon U-Pb and Pb/Pb dates in acid metavolcanics which dominate in the lower section of these sequences, and in coeval metaplutonics (granitic augen gneisses). From the stratigraphic point of view, three Staterian belts are recognized: 1. Orós Belt - made up by the Orós Group, subdivided in the Santarém (predominantly pure to impure quartzites, micaschists and metacarbonates) and Campo Alegre (metandesites, metabasalts, metarhyolites and metarhyodacites, interlayered with metatuffs and metasediments) formations, and by the Serra do Deserto Magmatic Suite (granitic augen gneisses). 2. Jaguaribe Belt - its lithostratigrahic-lithodemic framework is similar to the one of the Orós Belt, however with a greater expression of the volcano -plutonic components (Campo Alegre Formation and Serra do Deserto Magmatic Suite). The Peixe Gordo Sequence, separately described, is also related to this belt and contain s metasedimentary, metavolcanic (with subordinated volcanoclastics) and metaplutonic units. The first one correlated to the Orós Group and the latter the Serra do Deserto Magmatic Suite. 3. Western Potiguar Belt - represented by the Serra de São José Gro up, subdivided in the Catolezinho (biotite -amphibole gneisses with intercalations of metacarbonates, calcsilicate rocks, amphibolites and quartzite beds to the top) and Minhuins (quartzites, micaschists, metaconglomerates, calcsilicate rocks, acid to the b asic metavolcanics and metatuffs) formations. Its late Paleoproterozoic (Staterian) age was established by a Pb/Pb date on zircons from a granitic orthogneiss of the Catolezinho Formation. The petrographic characteristics and sedimentary structures of the Santarém Formation of the Orós Group point to deltaic to shallow marine depositional systems, overlain by deep water deposits (turbidites). The geodynamic setting of this region encompassed a large depositional basin, probably extending to the east of the Portalegre shear zone and west of the Senador Pompeu shear zone, with possible equivalents in the Jucurutu Formation of the Seridó Belt and in the Ceará Group of central Ceará. The Arneiróz Belt, west Ceará, displays some stratigraphic features and granito ids geochemically akin to the ones of the Orós Belt. The evolutionary setting started with an extensional phase which was more active in the eastern part of this domain (Western Potiguar and part of the Jaguaribe belts), where the rudite and psamite sedime ntation relates to a fluviatile rift environment which evolved to a prograding deltaic system to the west (Orós Group). The basaltic andesitic and rhyolitic volcanics were associated to this extensional phase. During this magmatic event, acid magmas also crystallized at plutonic depths. The Orós Group illustrates the environmental conditions in the western part of this domain. Later on, after a large time gap (1.6 to 1.1 Ga), the region was subjected to an extensional deformational episode marked by 900 Ma old (Sm-Nd data) basic rocks, possibly in connection with the deposition of the Cachoeirinha Group south of the Patos shear zone. In the 800 to 500 Ma age interval, the region was affected by important deformational and metamorphic events coupled with in trusion of granitic rocks of variable size (dykes to batholiths), related to the Brasiliano/Pan -African geotectonic cycle. These events produced structural blocks which differentiate, one from the other, according to the importance of anatectic mobilizatio n, proportion of high-grade supracrustals and the amount of neoproterozoic -cambrian granitoid intrusions. On this basis, a large portion of the Jaguaretama Block/Terrane is relatively well preserved from this late overprint. The border belts of the Jagua retama Block (Western Potiguar and Arneiroz) display kyanite-bearing (medium pressure) mineral associations, while in the inner part of the block there is a north-south metamorphic zoning marked by staurolite or sillimanite peak metamorphic conditions. Regarding the deformations of the Staterian supracrustal rocks, second and third phases were the most important, diagnosed as having developed in a progressive tectonic process. In the general, more vigorous conditions of PT are related to the interval tardi - phase 2 early-phase 3, whose radiometric ages and regional structuring indicators places it in the Brasiliano/Pan-African Cycle. In the Staterian geodynamic setting of Brazilian Platform , these sequences are correlated to the lower Espinhaço Supergroup (p.ex., Rio dos Remédios and Paraguaçu groups, a paleproterozoic rift system in the São Francisco Craton), the Araí and Serra da Mesa groups (north of Goiás, in the so -called Goiás Central Massif), and the Uatumã Group (in the Amazonian Craton). Granitic ( augen gneisses) plutonics are also known from these areas, as for example the A-type granites intrusive in the Araí and Serra da Mesa groups, dated at 1.77 Ga. Gravimetric and geological data place the limits of the Jaguaribeano System (terranes) along the Senador Pompeu Shear Zone (western border) and the Portalegre- Farias Brito shear zone (eastern and southern). However, the same data area not conclusive as regards the interpretation of those structures as suture of the terrane docking process. The main features of those shear zones and of involved lothological associations, appear to favour an intracontinental transpressional -transcurrent regime, during Neoproterozoic-Cambrian times, marking discontinuities along which different crustal blocks were laterally dispersed. Inside of this orogenic system and according to the magnetic data (total field map), the most important terrane boundary appears to be the Jaguaribe shear zone. The geochronological data, on some tectonostratigraphic associations (partly represented by the Ceará and Jucurutu groups), still at a preliminary level, besides the lack of granitic zonation and other petrotectonic criteria, do not allow to propose tectonic terrane assembly diagrams for the studied area

Caracterização morfológica e sedimentar do talude continental (foz do Amazonas)

Created on 3 december 1997, the REMPLAC (Program for Assessment of Mineral Potencial of the Continental Shelf), this porgram aimed to make the basic survey, systematic geological and geophysical continental shelf, detail, at an appropriate scale, sites geo-economic, and perform the analysis and evaluation of mineral deposits. The REMPLAC should continue the efforts of Global Recognition Program of the Brazilian Continental Margin REMAC closed in 1978, the operations Geophysical Sea (GEOMAR) developed by the Directorate of Hydrography and Navigation and the various initiatives of the Program of Marine Geology and Geophysics (PGGM). Despite the high interest on the Amazon platform, there is little information o their morphology and sediment characterization, and in order to fill this gap, the present work samples sedimentological point followed by seismic acquisition. And the studies were to characterize the possible area of interest as being directly influence by tides, which sediments are reworked throughout the platform featuring grain angle with sharp corners, and the carbonate content increases as it approaches the breakdown the platform, and the bodies found outside the foraminifera and mollusks. However, diverging with organic matter that reduces its concentration as it moves away from the coast. The seismic profiles do not get satisfactory results because of low visibility, however, to correlate with the spot samples, of sediment were possible morphological characterization of the area.

Desempenho, características de carcaça e resultado econômico de cordeiros criados em creep feeding com silagem de grãos úmidos de milho

Objetivou-se, com este trabalho, estudar níveis de substituição (0; 50 e 100%) do milho grão seco moído pela silagem de grãos úmidos de milho na ração de cordeiros alimentados em creep feeding. Vinte e quatro cordeiros Suffolk foram avaliados quanto ao desempenho, pesos e rendimentos das carcaças. Também foi realizada uma análise econômica. As rações foram fornecidas ad libitum, sendo suas sobras pesadas para o cálculo do consumo médio por animal. Ao atingirem 28 kg de peso vivo, os cordeiros foram submetidos a jejum por 16 horas e, então, novamente pesados para se obter o peso vivo ao abate. Após o abate, os animais foram eviscerados para se obterem os pesos e rendimentos de carcaça quente. As carcaças permaneceram por 24 horas em câmara de refrigeração, sendo novamente pesadas para se obterem os rendimentos de carcaça fria e as perdas por resfriamento. Os resultados revelaram que não houve efeito dos níveis de substituição sobre ganho médio diário de peso vivo, idade ao abate, pesos e rendimentos das carcaças quentes e frias, indicando que a silagem de grãos úmidos de milho pode ser utilizada em substituição ao milho moído na alimentação de cordeiros. Como o peso ao abate foi pré-fixado, as variações nas idades ao abate fizeram com que essa variável exercesse influência sobre os desempenhos, pesos e rendimentos e, quanto maiores essas idades, piores os resultados dos parâmetros avaliados. O tratamento com 50% de silagem de grãos úmidos apresentou os melhores resultados econômicos e o tratamento sem silagem de grãos úmidos foi o de menor rentabilidade.

Qualidade da carne de cordeiros criados em creep feeding com silagem de grãos úmidos de milho

Objetivou-se, com este trabalho, estudar níveis de substituição (0; 50 e 100%) do milho grão seco moído pela silagem de grãos úmidos de milho (SGUM) na ração de cordeiros alimentados em creep feeding. Vinte e quatro cordeiros Suffolk foram avaliados quanto às características quantitativas e qualitativas do músculo longissimus dorsi. Os animais foram abatidos ao atingirem 28 kg PV e suas carcaças resfriadas foram seccionadas em sete regiões anatômicas. Sobre a superfície do longissimus dorsi, no corte denominado lombo, foram tomadas as medidas: largura e profundidade máximas; mínima e máxima espessuras de gordura de cobertura e área de olho de lombo. Nos lombos, determinaram-se as proporções dos tecidos muscular, adiposo e ósseo, a composição química e a força de cisalhamento. Os resultados revelaram que não houve efeito dos tratamentos para a força de cisalhamento e nem para as medidas tomadas no longissimus dorsi, exceto para a área de olho de lombo, segundo regressão quadrática, com maiores valores para os tratamentos com SGUM. As análises de composição química do longissimus dorsi revelaram que os tratamentos influenciaram o teor de gordura no músculo, que aumentou linearmente de acordo com a inclusão de SGUM na ração. Não foi verificado efeito dos tratamentos sobre a composição tecidual dos lombos. Concluiu-se que é possível recomendar a substituição do milho grão pela silagem de grãos úmidos de milho para a dieta de cordeiros terminados em creep feeding, conservando a boa qualidade da carne.
