Saúde, trabalho e ambiente no meio rural brasileiro
Peres,Frederico;
Ciência & Saúde Coletiva , 2009, DOI: 10.1590/S1413-81232009000600007
Abstract: this manuscript discusses the implications of the productive paradigm changes in health and environment of rural area of brazil. it analyzes production, economy and demography data, facing social and structural determinants with health and environmental reflexes, revealing a serious panorama that includes: a) environmental impacts associated to large productive chains, such as corn, soy-bean, cotton and sugar cane; b) chemical contamination of diverse environment compartments due to pesticides and fertilizers used in agriculture; c) the use of natural land in the expansion of agriculture and cattle farming activities; and d) the reflexes of these actions on individuals, workers or not, that are more and more forced to deal with extreme vulnerability situations because of the risk of rural work processes. thus, the present article points that macro-determinants (or driven-forces) tends to configure the health status of rural brazil inhabitants which, day after day, face a series of challenges in order to guarantee dignity in their work and quality of life.
Solvability of a nonlinear boundary value problem

ACTA MATHEMATICA UNIVERSITATIS COMENIANAE , 2013,
Abstract: We study the existence and multiplicity of positive solutions of a nonlinear second order ordinary differential equation with symmetric nonlinear boundary conditions where both of the nonlinearities are of power type.

Karla Peres
Revista ACB , 2009,

Abstract: Relato de experiência que pretende divulgar a importancia do Setor de Documenta o para a Administra o Regional do Senac Santa Catarina. Apresenta um breve histórico do Senac que é uma empresa conceituada em educa o profissional no Brasil, suas áreas de atua o, seus objetivos e sua miss o. Aborda os conceitos de cada termo definidos por autores da área. Apresenta o espa o físico utilizado pelo setor de documenta o, suas atribui es, atividades desenvolvidas, o perfil da equipe, e suas responsabilidades no processo administrativo da empresa. Mostra como as atividades do Setor de Documenta o s o desenvolvidas atualmente, bem como os projetos que est o sendo desenvolvidos para melhorar, agilizar e facilitar essas atividades. Ressalta como as atividades do setor tem rela o direta com todos os setores da Administra o Regional do Senac, e como as unidades do Senac distribuídas pelo estado se relacionam com a Administra o Regional por meio do Setor de Documenta o
As Implica es da Educa o Física Frente à Hierarquia dos Saberes Escolares
Giani Peres
Nuances : Estudos sobre Educa??o , 2009,
Abstract: Este artigo retrata a historicidade do componente curricular Educa o Física, bem como reconhece a posi o de inferioridade e de marginalidade desse componente frente à hierarquia do saber escolar. Discute-se ainda a quest o da forma o dos/as futuros/as profissionais da educa o desta área do conhecimento que, além de precária, acaba por contribuir para com a perpetua o do status quo. Analisa a Educa o Física frente aos PCNs (Parametros Curriculares Nacionais), que por sua vez, s o fruto do MEC (Ministério da Educa o e do Desporto) com base na Nova LDB (Lei de Diretrizes e Bases da Educa o Brasileira). Por fim, busca-se real ar alternativas viáveis para conscientiza o dos/as futuros/as profissionais, a fim de extinguir o viés da hierarquia dos saberes que prima pela valoriza o de um/s determinado/s componente/s em detrimento de outros.

This paper portraies the historical context of the curricular component Physical Education, as well it recognizes the position of inferiority and marginality of this component in the school′s hierarchy of knowing. It also discusses the formation of future education professionals from this area of the knowledge which, beyond precarious, even contributes to perpetuate the status quo. This paper analyses the Physical Education in the school context and it is based on the PCNs, a product of MEC and the new LDB. At last it searches to enhance viable alternatives for the conscientization of future education professionals, in order to suppress the bias of the school′s hierarchy of the knowledge, order which valorizes a specific component in detriment to another.

Chaotic Evolution in Quantum Mechanics
Asher Peres
Physics , 1995, DOI: 10.1103/PhysRevE.53.4524
Abstract: A quantum system is described, whose wave function has a complexity which increases exponentially with time. Namely, for any fixed orthonormal basis, the number of components required for an accurate representation of the wave function increases exponentially.

Collective tests for quantum nonlocality
Asher Peres
Physics , 1996, DOI: 10.1103/PhysRevA.54.2685
Abstract: Pairs of spin-1/2 particles are prepared in a Werner state (namely, a mixture of singlet and random components). If the random component is large enough, the statistical results of spin measurements that may be performed on each pair separately can be reproduced by an algorithm involving local ``hidden'' variables. However, if several such pairs are tested simultaneously, a violation of the Clauser-Horne-Shimony-Holt inequality may occur, and no local hidden variable model is compatible with the results.
All the Bell inequalities
Asher Peres
Physics , 1998,
Abstract: Bell inequalities are derived for any number of observers, any number of alternative setups for each one of them, and any number of distinct outcomes for each experiment. It is shown that if a physical system consists of several distant subsystems, and if the results of tests performed on the latter are determined by local variables with objective values, then the joint probabilities for triggering any given set of distant detectors are convex combinations of a finite number of Boolean arrays, whose components are either 0 or 1 according to a simple rule. This convexity property is both necessary and sufficient for the existence of local objective variables. It leads to a simple graphical method which produces a large number of generalized Clauser- Horne inequalities corresponding to the faces of a convex polytope. It is plausible that quantum systems whose density matrix has a positive partial transposition satisfy all these inequalities, and therefore are compatible with local objective variables, even if their quantum properties are essentially nonlocal.
