A seleção dos conteúdos cartográficos presentes na proposta curricular dos cadernos São Paulo faz escola de geografia do 6. ano do ensino fundamental II

Cartography is one of the languages that express the knowledge of the geographic space and, therefore, the official curriculum proposals have highlighted the importance of the geography teaching which articulates its contents with this language in primary education. So, we present an analysis of the content selected to the curriculum mapping specifications of the São Paulo faz escola material, specifically for the 6th year of Elementary School II, version 2009. From the perspective of qualitative research, with instruments and techniques of quantitative and qualitative research, we analyzed documents and observed little concern with the proposition works that present the physical and social characteristics of the state of São Paulo. Also, we noticed the lack of concern with representations in local and regional scales. The research brings many examples on the global scale. It explores few activities using graphics and charts. Despite bringing thematic maps in their entirety, it does not show an example of conical projection as well as cartograms and anamorphosis. Furthermore, the trend of a technicist education is announced in the document

Estudo e caracterização térmica da curcumina e de uma forma polimórfica

This paper was prepared a polymorphic from of curcumin a natural bioactive compound widely used in Indian medicine in the treatment of a range of illnesses. The preparation was the polymorphic crystallization process and solvent mixtures of organic solvents in order to change the dielectric constant of the solution to obtain crystals. The crystal of curcumin has been studied and characterized by absorption spectroscopic in the infrared, X-ray diffraction powder method and by thermo analytical techniques: thermogravimetry and differential therma analysis (TG-DTA) and differential scanning calorimetry (DSC). The DSC of the pure compound (MP=180,19ºC) showed some differences compared the compound crystallized (MP=176.63ºC) in a mixture of solvents thus indicating the phenomenon of polymorphism, and TG-DTA curve of the compound crystallized showed that this was not a solvatomorphic. Finnally the techniques of X-ray diffraction technique FTIR and powder showed a structural change in the compound crystallized, profile-based graphics when compared to the pure compound, which proves that the compound crystallized it is a polymorph

Estudo teórico da contribuição a dose de partículas secundárias geradas por prótons de energias entre 100-200 MeV num phantom de músculo estriado

In the treatment plans in conventional Proton therapy are considered only the elastic interactions of protons with electrons and/or nuclei, it means, mainly ionization and coulomb excitation processes. As the energy needed to reach the deep tumors should be of several hundred of MeVs, certainly the nuclear inelastic channels are open. Only some previous studies of the contribution of these processes in the full dose have been made towards targets composed of water. In this study will be presented the results of the simulation of the processes of interaction of beams of protons in the range of 100-200 MeV of energy with a cylindrical phantom composed by striated muscle (ICRU), emphasizing in the contribution to total dose due to the deposition of energy by secondary particles alpha (α), deuterium (2H), tritium (3H), neutron (n) and hélio3 (3He), originated by nuclear inelastic processes. The simulations were performed by using the method of Monte Carlo, via the computer code MCNPX v2.50 (Monte Carlo N-Particle eXtended). The results will be shown demonstrated through the graphics of the deposited dose with or without nuclear interaction, the percentual of dose deposited by secondary particles, the radial dispersion of neutrons, as well as the multiplicity of secondary particles

Análise estatística da vida em fadiga de compósitos estruturais pela distribuição de Weibull

Nowadays technological trend is based on finding materials that could support low weight with satisfactory mechanical properties and for this reason composite material became a very attractive topic in research projects all over the world. Due to its heterogenic properties, this type of material shows scatter in mechanical test results, especially in cyclic loading. Therefore it is important to predict its fatigue strength behaviour by statistic analysis, once fatigue causes approximately 90% of the failure in structural components. The present work aimed to investigate the fatigue behaviour of the Twill/Cycom 890 composite, which is carbon fiber reinforced with polymeric resin as matrix and manufactured via RTM process (Resin Transfer Molding). All samples were tested in different tensile level in triplicate in order to associate these values. The statistical analysis was conducted with Two-Parameter Weibull Distribution and then evaluated the fatigue life results for the composite. Weibull graphics were used to determine the scale and shape parameters. The S-N curve for the Twill/Cycom composite was drawn and indicated the number of cycles to occur the first damages in this material. The probability of failure was associated with material reliability, as shown in graphics for the different tensile levels and fatigue life. In addition, the laminate was evaluated by ultrasonic inspection showing a regular impregnation. The fractographic analysis conducted by SEM showed failure mechanisms for polymeric composites associated to cyclic loadings ... (Complete abstract click electronic access below)

Estudo teórico da contribuição à dose de partículas secundárias geradas por Prótons de energias entre 100 e 200 MeV num Phantom de osso cortical

In proton therapy, the deposition of secondary particles energy originated by nuclear inelastic process (n, 2H, 3H, 3He and α) has a contribution in the total dose that deserves to be discussed. In calculations of plans implemented for routine treatment, the paid dose is calculated whereas the proton loses energy by ionization and or coulomb excitement. The contribution of inelastic processes associated with nuclear reactions is not considered. There are only estimates for pure materials or simple composition (water, for example), because of the difficulty of processing targets consisting of different materials. For this project, we use the Monte Carlo method employing the code MCNPX v2.50 (Monte Carlo N-Particle eXtended) to present results of the contribution to the total dose of secondary particles. In this work, it was implemented a cylindrical phantom composed by cortical bone, for proton beams between 100 and 200 MeV. With the results obtained, it was possible to generate graphics to analyze: the dose deposition relation with and without nuclear interaction, the multiplicity and percentage of deposited dose for each secondary particle and a radial dispersion of neutrons in the material

O ensino do desenho para crianças e jovens

Through my experiences as a teacher assistant in a free course design, I seek to understand the intentions and needs of children and youth with the design, so as to work it in a more consistent as the season and wishes of each student. For this I seek aid in studies on children's drawing of Derdyk Edith and also in observing the relationships that children and young people have with the drawing held in my practice as a teacher. Still reflect on the design in some of its particulars, especially concerning the optics of some artists and scholars of the practice of drawing. At the end of the study, propose suggestions for practices to be developed with children and young people who would be various forms of working drawing with experimental forms of building graphics, aiming so that students can add these unique experiences to broaden their understanding of design as well as its arch graphic possibilities. Thus inspired, especially in Derdyk considerations about the experimental design, I can conclude that through experimentation, we can offer young people a diverse thinking design and the possibilities of conceiving it.

Web Services Aplicados à Visualização

With the rapid growth of the use of Web applications in various fields of knowledge, the term Web service enter into evidence in the current scenario, which refers to services from different origins and purpose, offered through local networks and also available in some cases, on the Internet. The architecture of this type of application offers data processing on server side thereby, running applications and complex and slow processes is very interesting, which is the case with most algorithms involving visualization. The VTK is a library intended for visualization, and features a large variety of methods and algorithms for this purpose, but with a graphics engine that requires processing capacity. The union of these two resources can bring interesting results and contribute for performance improvements in the VTK library. This study is discussed in this project, through testing and communication overhead analysis

Estudo preliminar do potencial de alguns asteroides

A survey we conducted, and bring expressed in this text is a preliminary study on the shape of asteroids and allowed us to understand a little more the dynamics around these bodies, in order that the images we have of asteroids are the most irregular possible. In this work, the asteroid is modeled by the method of the polyhedron, which provides a very good accuracy of the irregular shape of the body. Through study of models for non-spherical gravitational potential bodies, implementation of computational algorithms and numerical simulations a preliminary analysis was performed in relation to the shape of asteroids 4179 Toutatis, 6489 Golevka, 2063 Bacchus, 1620 Geographos and 1998 ML14, as well as regions of stability instability, we compute the coefficients of the gravitational potential. The work not only enables expansion for the case of asteroids, but also for other non-spherical bodies, contributing to the development of targeted studies the origin and evolution of the solar system, and perhaps the origin of the earth, and new technologies for modeling and mapping of non-spherical bodies. The main results were obtained by analyzing the graphics format and planning of asteroids, which confirmed how these bodies are irregular and show how distribution of non-homogeneous mass. Observe the behavior of the curves of zero velocity and equipotential curves as well as their respective surfaces. Also, compute some values of the gravitational potential and the spherical harmonic coefficients of each object. Furthermore, we find possible equilibrium points of asteroids except 4179 Toutatis, and analyze its stability

Bridging hydraulic diffusivity from aquifer to particle-size scale: a study on loess sediments from southwest Hungary

In situ megascale hydraulic diffusivities (D) of a confined loess aquifer were estimated at various scales (10 <= L <= 1500 m) by a finite difference model, and laboratory microscale diffusivities of a loess sample by empirical formulas. A scatter plot reveals that D fits to a single power function of L, providing that microscale diffusivities are assigned to L = 1 m and that differences in diffusivity observed between micro- and megascales are assigned to medium heterogeneity appraised by variations in the curvature and slope of natural hydraulic head waves propagating through the aquifer. Subsequently, a general power relationship between D and L is defined where the base and exponent terms stand for the aquifer storage capability under a confined regime of flow, for the microscale hydraulic conductivity and specific yield of loess, and for the changes in curvature and slope of hydraulic head waves relative to values defined at unit scale.[GRAPHICS]Editor Z.W.
