A Tese trata da cidade de São Luis do Maranhão no final do século XIX e XX. Analisa aspectos do imaginário sobre a cidade localizada em uma ilha que se percebe integrada ao Continente ao país e à Europa. Discorre sobre a perspectiva de civilização da América a partir do pensamento de Rodó, Fecundo, Manoel Bonfim, Leopoldo Zea e à maneira como os moradores da São Luís buscaram reconhecimento da cidade como detentora de civilidade. Observa como os ludovicenses lidaram com as marcas da escravidão que evidenciavam a barbárie, e segundo o pensamento do século XIX, deveria ser erradicada. Trata do processo que transformou em símbolo de cultura da cidade a manifestação popular, bumba meu boi, antes coisa de bárbaro, condenada ao subúrbio da ilha. Mostra que a preservação presente nas representações dos álbuns de fotografia da cidade é de “fachadas”, mas que permitiu preservar casarões do século XIX, e possibilitou uma nova classificação de São Luís como a quinta cidade brasileira a receber o título de Patrimônio da Humanidade, um retorno, uma nova inserção, um destaque entre as cidades brasileiras. A análise foi realizada a partir de fontes iconográficas, mapas, literatura, e jornais.

O sistema de águas subterrâneas vigentes na cidade de Manaus (AM) é pertencente ao Aqüífero Alter do Chão, o qual é caracterizado por fácies sedimentares arenosa, argilosa, areno-argilosa e “Arenito Manaus” depositadas em ambiente fluvial e flúvio-deltáico. Estima-se que 32.500 km3 de água possam ser explorados, fornecendo poços confinados a semiconfinados com vazão de até 300 m3/h em poços de aproximadamente 220 m de profundidade. Grandes distorções, contudo, têm sido notadas, Manaus, em foco neste trabalho, tem poços com baixo rendimento (de 78 m3/h), devido à má colocação de filtros em conseqüência da falta de informações sobre os aqüíferos. Através do uso integrado de perfilagem geofísica de poço (perfis de raio gama, de potencial espontâneo e de resistência elétrica), sondagem elétrica vertical e informações litológicas de amostragem de calha, mapearam-se camadas litológicas permo-porosas com elevado potencial aqüífero nas zonas norte e leste da cidade de Manaus. Foram identificadas duas zonas aqüíferas. A primeira zona é marcada pelos 50 m iniciais de profundidade. Nesta zona distinguem-se três tipos de litologias: argilosa, arenosa e areno-argilosa com as mais variadas dimensões. Estas duas últimas litologias apresentam elevado potencial aqüífero. Mesmo assim, nesta zona não há tendência a conter um volume de água considerável, devido à limitada continuidade lateral dos corpos arenosos e estar sujeita aos estorvos antrópicos superficiais. Portanto, não indicada para explotação de água em grandes quantidades. A segunda zona se estende a partir dos 50 m até aproximadamente 290 m de profundidade. É caracterizada por dois tipos de litologias: arenosa e areno-argilosa. Ao contrário da primeira, a esta profundidade há propensão do armazenamento e exploração de água. Apresenta litologias com elevado potencial aqüífero, cujos corpos arenosos são mais espessos e possuem uma maior continuidade lateral que os da zona 1; e valores da veza o de quase 300 m3/h. Serve, então, para abastecimento público por causa das boas vazões, garantia de água de boa qualidade protegida de ações antrópicas. A análise feita quanto à variação lateral, em mapas, de resistência transversal e condutância longitudinal, revelou que nas porções inferiores a 50 m de profundidade os setores NE e SW correspondem às zonas permeáveis. Portanto, possuem menos faixas argilosas, sendo considerados os setores mais transmissivos do sistema aqüífero. Os poços com profundidade maiores que 50 m recomenda-se sua locações nas faixas NNW, SW e extremo sul, em virtude dos resultados obtidos através da perfilagens geofísicas de poços, as quais delineiam camadas permo-porosas de elevado potencial aquífero para a área estudada.

The Lewis blood group system involves two major antigens, Leª and Leb. Their antigenic determinants are not primary gene products but are synthesized by the transfer of sugar subunits to a precursory chain by a specific enzyme which is the product of the FUT3 gene (Lewis gene). The presence of three FUT3 gene single nucleotide polymorphisms (SNPs) (59T > G; 508G > A and 1067T > A) was related to the Lewis phenotype of erythrocytes from 185 individuals of Japanese ancestry living in the town of Tomé-Açu in the Brazilian Amazon region. This relationship was detected using a serological hemagglutination test and the Dot-ELISA assay along with the molecular technique PCR-RFLP. We found that the three SNPs investigated in this study only accounted for a proportion of the Lewis-negative phenotype of the erythrocytes.

The sampling scheme is essential in the investigation of the spatial variability of soil properties in Soil Science studies. The high costs of sampling schemes optimized with additional sampling points for each physical and chemical soil property, prevent their use in precision agriculture. The purpose of this study was to obtain an optimal sampling scheme for physical and chemical property sets and investigate its effect on the quality of soil sampling. Soil was sampled on a 42-ha area, with 206 geo-referenced points arranged in a regular grid spaced 50 m from each other, in a depth range of 0.00-0.20 m. In order to obtain an optimal sampling scheme for every physical and chemical property, a sample grid, a medium-scale variogram and the extended Spatial Simulated Annealing (SSA) method were used to minimize kriging variance. The optimization procedure was validated by constructing maps of relative improvement comparing the sample configuration before and after the process. A greater concentration of recommended points in specific areas (NW-SE direction) was observed, which also reflects a greater estimate variance at these locations. The addition of optimal samples, for specific regions, increased the accuracy up to 2 % for chemical and 1 % for physical properties. The use of a sample grid and medium-scale variogram, as previous information for the conception of additional sampling schemes, was very promising to determine the locations of these additional points for all physical and chemical soil properties, enhancing the accuracy of kriging estimates of the physical-chemical properties.

Bacterial artificial chromosomes (BAC) have been widely used for fluorescence in situ hybridization (FISH) mapping of chromosome landmarks in different organisms, including a few in teleosts. In this study, we used BAC-FISH to consolidate the previous genetic and cytogenetic maps of the turbot (Scophthalmus maximus), a commercially important pleuronectiform. The maps consisted of 24 linkage groups (LGs) but only 22 chromosomes. All turbot LGs were assigned to specific chromosomes using BAC probes obtained from a turbot 5x genomic BAC library. It consisted of 46,080 clones with inserts of at least 100 kb and < 5 % empty vectors. These BAC probes contained gene-derived or anonymous markers, most of them linked to quantitative trait loci (QTL) related to productive traits. BAC clones were mapped by FISH to unique marker-specific chromosomal positions, which showed a notable concordance with previous genetic mapping data. The two metacentric pairs were cytogenetically assigned to LG2 and LG16, and the nucleolar organizer region (NOR)-bearing pair was assigned to LG15. Double-color FISH assays enabled the consolidation of the turbot genetic map into 22 linkage groups by merging LG8 with LG18 and LG21 with LG24. In this work, a first-generation probe panel of BAC clones anchored to the turbot linkage and cytogenetical map was developed. It is a useful tool for chromosome traceability in turbot, but also relevant in the context of pleuronectiform karyotypes, which often show small hardly identifiable chromosomes. This panel will also be valuable for further integrative genomics of turbot within Pleuronectiformes and teleosts, especially for fine QTL mapping for aquaculture traits, comparative genomics, and whole-genome assembly.

Convergence to a period one fixed point is investigated for both logistic and cubic maps. For the logistic map the relaxation to the fixed point is considered near a transcritical bifurcation while for the cubic map it is near a pitchfork bifurcation. We confirmed that the convergence to the fixed point in both logistic and cubic maps for a region close to the fixed point goes exponentially fast to the fixed point and with a relaxation time described by a power law of exponent -1. At the bifurcation point, the exponent is not universal and depends on the type of the bifurcation as well as on the nonlinearity of the map.

Geological-geotechnical problems affecting escarps as well as embankment and fill slopes of roads and motorways may generate different types of unsteadiness, which are mainly arisen from the deficient knowledge about the physical environment. This results in unsuitable engineering projects and inadequate executions, which can be worsened by an occasional inappropriate maintenance of the construction. A geologically-geotechnically characterization of escarps and slopes is crucial in order to prevent these problems. This work deals with a geological-geotechnical study of 1:10.000 scale mapping in a stretch of a local road (CHQ-40) at the Serra de Itaqueri, Charqueada town, State of São Paulo. The stretch is known by several physical problems as erosion and mass movement. The methods of study were based on an integrative analysis of the diverse elements of the physical environment by using aerial photographs - to obtain the physiographic compartmentalization of terrain units - as well as field work - to accomplish the evaluation of the units by employing sketch lists. To achieve this, we selected several techniques in order to identify and classify different types of existing problems as erosion, landslide in embankments and fill slopes, rockfall, block rolling, among others. We also included the analysis of soil horizon, thickness and composition. The geological-geotechnical mapping resulted in six units: 1- Sandstones in cuesta’s backhill; 2 – Basalts in cuesta’s front; 3- Sandstones in cuesta’s front; 4 – Talus and colluvial deposits at cuesta’s foothill; 5- Sandstones of the Piramboia Formation in hillside; and 6 – Colluvial soil in the hill top. A characterization of the geological-geotechnical units is detailed, coupled to the cartographic material. Other cartographic products elaborated for this study included 1:10.000 maps of hypsometry, slope and curvature
