The Lamination of Infinitely Renormalizable Dissipative Gap Maps: Analyticity, Holonomies and Conjugacies

Motivated by return maps near saddles for three-dimensional flows and also by return maps in the torus associated to Cherry flows, we study gap maps with derivative positive and smaller than one outside the discontinuity point. We prove that the lamination of infinitely renormalizable maps (or else maps with irrational rotation numbers) has analytic leaves in a natural subset of a Banach space of analytic maps of this kind. With maps having Hölder continuous derivative and derivative bounded away from zero, we also prove Hölder continuity of holonomies of the lamination and also of conjugacies between maps having the same combinatorics. © 2011 Springer Basel AG.

Optimization of the sampling scheme for maps of physical and chemical properties estimated by kriging

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.

Consolidation of the genetic and cytogenetic maps of turbot (Scophthalmus maximus) using FISH with BAC clones

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.

Relaxation to Fixed Points in the Logistic and Cubic Maps: Analytical and Numerical Investigation

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.

Augusta: Rua de mão dupla

This project is about a book-report, which will discuss the Augusta Street in São Paulo, a place emblematic of the city, one of its biggest and most famous streets and that has been the scene of several transformations of the country. From the heady days of Jovem Guarda to the decadence of the inferninhos locus of prostitution and drugs. Currently the route passes through a dubious process of revitalization. Then comes the question of when life ceased to exist in Augusta and the desire to capture in words the transitory moment what is happening in this street. When you scroll through 3 km of the street you want to be seen as a flaneur, the two Augusta, one which lives on day and another whose life begins at night. Down the hills, draw a profile of one extraordinary street and lay bare the contradictions that make Augusta a two-way street

Escola de tempo integral: uma análise do processo de implantação na Escola Estadual Carolina Augusta Seraphim. -

No Brasil a educação é um tema delicado, com histórico de índices de reprovação e evasão escolar altos, escolas públicas em condições precárias em muitas regiões e profissionais da área pouco valorizados. As políticas públicas são uma importante ferramenta quando se busca sanar todos estes problemas. Uma proposta que vem sendo implantada no Estado de São Paulo é o das Escolas de Tempo Integral, em que os alunos têm a oportunidade de passar mais tempo na escola, com atividades diferenciadas e um modelo diferente da escola comum. Assim, este trabalho tem como objetivo analisar a proposta do modelo e a implementação do mesmo na Escola Estadual Carolina Augusta Seraphim, localizada em Rio Claro. Para a análise de conteúdo, realizada neste trabalho, foi feito o levantamento de material bibliográfico referente ao tema de Escola de Tempo Integral, principalmente no Estado de São Paulo. Também foram analisados documentos e materiais disponíveis no blog da EE Carolina Augusta Seraphim. Podem ser destacados pontos positivos do Programa, como a dedicação exclusiva da equipe gestora, a valorização dos profissionais envolvidos, a participação mais aproximada da comunidade e família dos alunos, a possibilidade que os estudantes têm de pensar e planejar seu futuro. Existem ainda questões a serem melhor debatidas, analisadas ou até mesmo aprimoradas, devido às particularidades de cada escola e até mesmo inovações tecnológicas que podem ser usadas como ferramentas de ensino. Essas são algumas das questões abordadas e analisadas ao longo do trabalho
