The Parity Violated Nucleon-Nucleon Potential (PVNN) is evaluated in the framework of Chiral Perturbation Theory (ChPT) in order to reduce theoretical uncertainties. Here I present a summary of the main results.

The franciscana, Pontoporia blainvillei, is endemic to the western South Atlantic Ocean and is perhaps one of the most threatened small cetacean species in this region. This paper presents a first abundance estimate for ...

Visando o ensino de Física de uma maneira mais atrativa aos alunos de 2° e 3° graus, desenvolvemos um programa que permite utilizar alguns tópicos de Mecânica na Investigação de Acidentes de Trânsito. Como precisávamos ...

Nesta dissertação, estudamos a produção de hádrons em processos de fragmentação de jatos, bem como alguns mecanismos de perda de energia, em colisões ultrarelativísticas de íons pesados, onde é esperada a produção de um ...

Este artigo descreve como distribuir dados das aplicações usando um middleware constituído por um Sistema de Gerenciamento de Banco de Dados em Memória como camada base; e uma camada de convergência adequada as aplicações. ...

Fractional derivatives and integrations of non-integers orders was introduced more than three centuries ago but only recently gained more attention due to its application on nonlocal phenomenas. In this context, several ...

We present a general formulation of the matrix product ansatz for exactly integrable chains on periodic lattices. This new formulation extends the matrix product ansatz present on our previous articles (F. C. Alcaraz and ...

Monthly strandings of South American sea lions, Otaria flavescens, and South American fur seals, Arctocephalus australis collected between 1993 and 2002 along the coastline of Rio Grande do Sul, Brazil, are analysed with ...

The paper discusses the transformation of decorated Ising models into an effective undecorated spin model, using the most general Hamiltonian for interacting Ising models including a long range and high order interactions. ...

Geometrically frustrated spin models with competing interaction parameters and the phase diagram of their corresponding T = 0 ground state energies are studied. The partition function defined by means of the transfer ...

Neste artigo discutimos a proposta do Projeto Escola-Comunidade-Universidade: buscando metodologias educativas, interativas e interconectivas em uma visão sistêmica (Escuna) e focamos o olhar na dinâmica de gestão de uma ...

In this paper, we investigate the influence of nuclear effects in the production of gluinos in nuclear collisions at the Large Hadron Collider, and estimate the transverse momentum dependence of the nuclear ratios RpA = ...

Growth models are an important component in the study of population biology and are generally required in fishery assessment. This paper is concerned with the fit of Schnute’s general growth model to an age-length key of ...

Much work have been done lately to develop complex motor control systems. However they always rely on a physical drive/motor/encoder setup for experimental results. This paper presents a hardware DC motor emulator that can ...

We study effects of the event-by-event fluctuation of the initial conditions and the continuous pion emission during the whole development of the hot and dense matter formed in high-energy collisions on the two-pion ...

We investigate heavy quark photoproduction based on the k'-factorization approach, focusing on the results from the saturation model. The deviations between the results using the unintegrated gluon distribution considering ...

We recall the many obstacles which seemed, long ago, to prevent supersymmetry from possibly being a fundamental symmetry of Nature. We also present their solutions, leading to the construction of the supersymmetric extensions ...

The potential impact of increasing vessel traffic and coastal development has led to concerns regarding the future of the Brazilian humpback whale Megaptera novaeangliae population. Our objective was to monitor humpback ...

Este artigo apresenta uma estratégia para identificar efeitos de locação e efeitos de dispersão em experimentos fatoriais não-replicados, fracionados ou não. A estratégia é adaptada para projetos experimentais com poucas ...

We study, in a hydrodynamical approach, the energy dependence of the kaon mT spectra in central Pb+Pb (Au+Au) collisions. We show that the experimental data of the inverse slope parameter can be reproduced with a reasonable ...
