Programa de Atenção ao aluno Precoce com Comportamentos de Altas Habilidades/Superdotação (PAPAHS)

This paper describes a Precocious Student Attention Program With High Abilities/Giftedness Behaviors developed since 2011 at Júlio Mesquita Filho Philosophy and Sciences São Paulo State University, located in the city of Marília/SP/Brazil. Based on Joseph Renzulli's three rings theory, the authors describe how they organized the process of identification and evaluation of the precocious children with giftedness behaviors that attend the program. Based on Joseph Renzulli's Enrichment Triad Model, the authors categorize the students and give an account of the enrichment activities that are developed alongside with the students and their respective guardians. It is concluded that programs of this nature serve this still little recognized category of students, as well as help the development of studies and is a significant locus to educational formation.

A produção acadêmico-científica do Brasil na área das altas habilidades/superdotação no período de 1987 a 2011

Among students with special educational needs, subjects of special education, are those with high ability/giftedness, a complex phenomenon that requires the participation of education professionals and researchers to foster the potential of development of these students. In this sense, we aimed to identify and analyze thesis and dissertations that they propose to investigate the theme high ability/giftedness, verifying participation of the area of education in these studies. The study was done through a literature review, guided by the following questions: Have the researches on high ability/giftedness been growing in recent years? What is the participation of education area in those researches? What are the issues related to high ability/ giftedness addressed in Education? The results show that the institutions present an increasing trend and there is a predominance of education area in this scientific production. However, there is an imbalance between the institutions that aim to investigate the theme in Brazilian regions, as well as among the cases covered by these researches on high ability/giftedness.

Reflexões sobre precoces, prodígios, gênios e as altas habilidades, com base na neurociência cognitiva. Revista Educação Especial

In special education, high skills designate people who demonstrate the capability, potential or performance in human activities, well above average. Our objective, using neuroscience to understand the early, prodigies, geniuses and high abilities as a result of a unique process of memory formation. It is a literature search, in which the works were identified, located, compiled, analyzed and blacklisted. The material was located from keywords in databases. For the compilation were used as inclusion criteria, adopted the intersection of the keywords as well as the work of researchers from education, psychology and neuroscience, published between 1966 and 2009; qualitatively analyzed 40 references, 18 articles and 22 other texts. The trajectory analysis was developed with the question: no need to explain differently the precocious prodigies, geniuses, and AH? We reached three logical propositions. We demonstrate through this exercise of course, that there would be no need to explain differently the precocious prodigies, geniuses, and AH, but conclude that there is need for such differentiation, even within the field of neuroscience, however, the statement above points to Renzulli’s theory as valid for geniuses and AH, with exceptions for early and wonders that deserve a closer look.

Doses, fontes e épocas de aplicação de nitrogênio em arroz de terras altas cultivado em sistema de semeadura direta

The crop demand by nitrogen varies from one crop to other as well as the amount and application time, and this nutrient can be lost by leaching, volatilization and erosion. The objective of this study was to evaluate doses, sources and times of nitrogen application in rice of high lands cropped in no till system. The work was conducted in Selviria, State of Mato Grosso do Sul, Brazil, in a soil originally under Cerrado vegetation. A randomized blocks design, with the treatments disposed in a factorial scheme 5x3x2 was used. The treatments were constituted by five nitrogen doses (0, 50, 100, 150 and 200 kg ha(-1)), three nitrogen sources (urea; ammonium sulfonitrate plus nitrification inhitor and ammonium sulfate) and two application times (at sowing or at flower bud differentiation), with four repetitions. The sources of nitrogen, as well as the application times had similar effects for most of evaluations. The N doses influenced linearly or with quadratic adjustment the plant height, N leaf content and grains yield, in the two growing seasons. The chlorophyll content and the number of ears m(-2) were affected only, in the first year. The highest yield in the growing season of 2007/08 was obtained with the dose of 149 kg ha(-1) of N. In 2008/09 growing season the increase of N doses provided increment in the grains rice yield, until the maximum dose evaluated (200 kg ha(-1) of N).

Estudo teórico da contribuição à dose de partículas secundárias geradas por prótons de energias entre 100 e 200 MeV num Phantom de substituto de tecido MS20

The goal of this project is the reproduction, through the simulation code based on the MCNPX (Monte Carlo N-Particle eXtended) v2.50 method, of the proton beam interaction with the material, since, in proton therapy, only the particle ionization and excitation are analyzed and the occurence of nuclear interactive inelastic process are not considered. This work will help the development of studies concerning the contribution to the total dosis of secondary particles generated by nuclear interaction in proton therapy. They are: alpha particles ( ), deuterium(2H), tritium (3H), neutron (n) and helium (3He). A MS20 tissue substitute phantom was used as the target and the energy of the proton beams was within an interest range of 100 to 200MeV. With the results obtained, it was possible to generate graphics which allows the analysis of the dosis deposition relation with and without nuclear interaction, the percentage of secondary particles deposited dosis, the radial dispersion of neutrons in the material, the secondary particles multiplicity, as well as the relation between the secondary particles spectrum with the próton generated spectrum

Avaliação de juntas soldadas em tubos de aço carbono submetidos a altas temperatura e pressões

The welding process in industrial piping is still the most effective way to ensure the durability and quality of the wide range of industrial process, although because of the high demand for energy and quality of the produced products, the piping has been constantly tested for high pressure applications and still high temperature. The welding method analyzed is the TIG (Tungsten Inert Gas) welding or GTAW (Gas-Shielded Tungsten Arc Welding), which ones have as principal feature the utilization of a not consumable tungsten electrode in the torch extremity , in this process is necessary a protective atmosphere of inert gas. The welding TIG advantage is the obtaining of a welded seam clean and with quality for not has slag after the welding. This work has as objective show the variability in the carbon steel piping welding parameters and by the tests in four proof bodies will be shown the influence of the variation of the welding methods in a welded seam. The tests will vary since the piece to be welded preparation, till penetrating liquid tests, welding macrography, welding x-ray and traction tests. Even been a clean and with quality welding is necessary a final inspection in the seam welded looking for defects almost inevitable resulted of the welded process, the obtained results have the objective of indicate and minimize the defects to ensure quality and durability of the welded seam

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

Energias alternativas: potencialidades para as regiões de maior demanda energética no Brasil

Since the beginning of life in society, the human being has sought sources of energy that can be used continuously, or stored to be consumed in times of need. The various energy generation processes has enabled the human race for the implementation of many activities ranging from food preparation, handling of large industries and even the possibility of total annihilation by the availability of powerful nuclear weapons. In Brazil, whereupon the various deleterious aspects and especially the finite resources used on a large scale for the energy conservation, there is a huge devotion of society referred to the prospects for alternatives to the use of energy in local, regional and global, but overall, as it wouldn’t be different, the main factors in this scenario are economic. The fact that the unused potential of a region in the use of alternative sources of energy leads to a larger socio-environmental prejudice generalized to all. The purpose of this project is targeted for a comprehensive, systemic and integrated discussion about some of the main alternative energy sources, associated with technical procedures related to them, to contribute to a better and effective use of natural resources available in each region of the country, in order to minimize the impacts on the environment in which they are inserted.

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
