Resumo: APRESENTAÇÂO: Este livro é resultado das ações de pesquisa e extensão do
projeto Diagnóstico dos Sistemas de Produção Agroextrativista da
Reserva Extrativista Chapada Limpa e da Comunidade Quilombola
Barro Vermelho, Chapadinha-MA, que foi aprovado pela FAPEMA
através do edital Nº 33/2015 AGRIF. O projeto foi executado no
período de 2016 a 2018.
Nesta publicação foi realizada uma análise e diagnóstico,
utilizando o enfoque sistêmico dos estabelecimentos agroextrativistas
(subsistemas de cultivo, criação e extrativismo), das infraestruturas e
das associações de duas localidades rurais situadas nos municípios de
Chapadinha (Reserva Extrativista Chapada Limpa) e Vargem Grande
(comunidade quilombola Barro Vermelho), que integram o território
Baixo Parnaíba, localizado no nordeste do Estado do Maranhão.
Espera-se que esta obra possa disponibilizar informações
para que os órgãos responsáveis pelas políticas de desenvolvimento
rural (Federal, Estadual e Municipal) tenham melhores condições
de implantarem projetos adequados aos sistemas de produção agro extrativista e que estes promovam melhorias na qualidade de vida
dessas famílias.___PRESENTATION: This book is the result of research and extension actions by the
Diagnosis of Agroextractivist Production Systems project
Chapada Limpa and Quilombola Community Extractive Reserve
Barro Vermelho, Chapadinha-MA, which was approved by FAPEMA
through public notice No. 33/2015 AGRIF. The project was carried out in
period from 2016 to 2018.
This publication carried out an analysis and diagnosis,
using the systemic approach of agroextractivist establishments
(cultivation, creation and extraction subsystems), infrastructure and
of the associations of two rural localities located in the municipalities of
Chapadinha (Extractive Reserve Chapada Limpa) and Vargem Grande
(Barro Vermelho quilombola community), which are part of the territory
Baixo Parnaíba, located in the northeast of the State of Maranhão.
It is hoped that this work will provide information
so that the bodies responsible for development policies
rural areas (Federal, State and Municipal) have better conditions
to implement suitable projects for agro-extractivist production systems and that these promote improvements in the quality of life
of these families.2020-01-01T00:00:00ZRELATÓRIO DE ESTÁGIO PÓS-DOUTORALLANDRIM, Aline Vieriahttps://repositorio.ufma.br/jspui/handle/123456789/8772018-04-02T17:05:37Z2018-01-01T00:00:00ZTítulo: RELATÓRIO DE ESTÁGIO PÓS-DOUTORAL

Autor(es): CASANA, R.; GOMES, A. R.; MENEZES, R.; SIMAS, Fabiano de Carvalho
Resumo: We have considered the localization of resonant bosonic states described by a scalar field Φ trapped in
tube-like topological defects. The tubes are formed by radial symmetric defects in (2, 1) dimensions,
constructed with two scalar fields φ and χ, and embedded in the (3, 1)-dimensional Minkowski
spacetime. The general coupling between the topological defect and the scalar field Φ is given by the
potential ηF (φ,χ)Φ2. After a convenient decomposition of the field Φ, we find that the amplitudes of
the radial modes satisfy Schrödinger-like equations whose eigenvalues are the masses of the bosonic
resonances. Specifically, we have analyzed two simple couplings: the first one is F (φ,χ) = χ2 for a
fourth-order potential and, the second one is a sixth-order interaction characterized by F (φ,χ) = (φχ)2.
In both cases the Schrödinger-like equations are numerically solved with appropriated boundary
conditions. Several resonance peaks for both models are obtained and the numerical analysis showed
that the fourth-order potential generates more resonances than the sixth-order one.2014-01-01T00:00:00ZTrapping Spin-0 particles on p-balls in (D, 1) dimensionsCASANA, R.GOMES, A. R.SIMAS, Fabiano de Carvalhohttps://repositorio.ufma.br/jspui/handle/123456789/8612018-03-09T20:04:40Z2015-01-01T00:00:00ZTítulo: Trapping Spin-0 particles on p-balls in (D, 1) dimensions
Autor(es): CASANA, R.; GOMES, A. R.; SIMAS, Fabiano de Carvalho
Resumo: p-Balls are topological defects in (D, 1) dimensions constructed with M≥1 scalar fields which depend radially on only 2 ≤ p ≤ D − 2 spatial dimensions. Such defects are characterized by an action that breaks translational invariance and are inspired on the physics of a brane with D − p extra dimensions. Here we consider the issue of localization of bosonic states described by a scalar field Φ sufficiently weak to not disturb sensibly the defect configuration. After describing the general formalism, we consider some specify examples with M = 1, 2 and 3, looking for some region of parameters where bound and resonant bosonic states can be found. We investigate the way the influence of the defect structure, number of radial dimensions and coupling between the fields are related to the occurrence of bound and resonant states.
