THE ROLE OF ECONOMIC AND SOCIOCULTURAL FUNCTIONS OF ANIMAL PRODUCTION IN WELLBEING AND DEVELOPMENT OF RURAL COMMUNITIES OF TIMOR-LESTE
Livestock production in Timor-Leste is predominantly familiar being chickens, pigs, goats, cattle, horses, buffaloes and sheep the main species.
The livestock species play very important economic and sociocultural roles for the well-being of rural households, such as food supply, source of income, asset saving, source of employment, soil fertility, livelihoods, transport, agricultural traction, agricultural diversification and sustainable agricultural production.
The aim of this work was to identify and characterize the different roles that livestock and livestock species play in rural communities of Timor-Leste, highlighting the importance of animal production for the wellbeing and rural development, and relate the functions performed by livestock production with economic, social and cultural attributes of the communities. The data used in this study were collected in 2011 through a questionnaire survey in three rural communities in the district of Bobonaro -mountain area, irrigation plain and coastal zone, and were complemented with secondary dat
Generic area-preserving reversible diffeomorphisms
Let M be a surface and R : M -> M an area-preserving C-infinity diffeomorphism which is an involution and whose set of fixed points is a submanifold with dimension one. We will prove that C-1 - generically either an area-preserving R-reversible diffeomorphism, is Anosov, or, for mu-almost every x is an element of M, the Lyapunov exponents at x vanish or else the orbit of x belongs to a compact hyperbolic set with an empty interior. We will also describe a nonempty C-1-open subset of area-preserving R-reversible diffeomorphisms where for C-1 - generically each map is either Anosov or its Lyapunov exponents vanish from almost everywhere

Aesthetic Education and Sensitivity from the Thought of Friedrich Schiller
In this article, we reflect on the aesthetic formation of man from the dialogue established between Friedrich Schiller and the Duke of Augustenburg, what we know today as the letters of Schiller. We try to problematize some theoretical assumptions present in these letters regarding the subject and how this constructions shapes subjectivity from aesthetic sensations. The objective of this research is to understand the (de) appreciation of the sensitive and the (dis) equilibrium between human nature, sensibility and aesthetic education of man, with Schiller's letters as a universe of reflection. It is a research of a bibliographic nature, of an exploratory-descriptive nature. The premises presented in the present study point out that the questions raised by the philosopher are still present to the understanding of how aesthetic formation dialogues with the constitution of subjectivities, morality and, above all, with the appreciation of sensitivities as mobilizers of human existence
Reconstrução tridimensional dinâmica do coração através da ecocardiografia transesofágica
Copyright © 1997-99 Arquivos Brasileiros de CardiologiaObjective – To evaluate echocardiography accuracy in performing and obtaining images for dynamical threedimensional (3D) reconstruction. Methods – Three-dimensional (3D) image reconstruction was obtained in 20 consecutive patients who underwent transesophageal echocardiography. A multiplanar 5 MHz transducer was used for 3D reconstruction. Results – Twenty patients were studied consecutively. The following cardiac diseases were present: valvar prostheses – 6 (2 mitral, 2 aortic and 2 mitral and aortic); mitral valve prolapse – 3; mitral and aortic disease – 2; aortic valve disease – 5; congenital heart disease – 3 (2 atrial septal defect –ASD- and 1 transposition of the great arteries -TGA); arteriovenous fistula – 1. In 7 patients, color Doppler was also obtained and used for 3D flow reconstruction. Twenty five cardiac structures were acquired and 60 reconstructions generated (28 of mitral valves, 14 of aortic valves, 4 of mitral prostheses, 7 of aortic prostheses and 7 of the ASD). Fifty five of 60 (91.6%) reconstructions were considered of good quality by 2 independent observers. The 11 reconstructed mitral valves/prostheses and the 2 reconstructed ASDs provided more anatomical information than two dimensional echocardiography (2DE) alone. Conclusion – 3D echocardiography using a transesophageal transducer is a feasible technique, which improves detection of anatomical details of cardiac structures, particularly of the mitral valve and atrial septum.Objetivo - Avaliar a acuidade da ecocardiografia na realização e obtenção de imagens para reconstrução tridimensional dinâmica (3D). Métodos - Foram obtidas imagens para reconstruções 3D em 20 doentes consecutivos submetidos a ecocardiografia transesofágica. Foi utilizado um transdutor de 5 Mhz multiplanar ligado ao sistema de reconstrução 3D. Resultados – Foram estudados, consecutivamente, 20 doentes, idade média de 56±16 anos, com as seguintes doenças cardíacas: próteses valvulares - 6 (2 mitrais, 2 aórticas e 2 mitro-aórticas); prolapso da válvula mitral - 3; doença mitro-aórtica - 2; doença da válvula aórtica - 5; cardiopatia congênita - 3 (2 comunicação interatrial (CIA) e 1 transposição das grandes artérias (TGA)); fístula arteriovenosa - 1. Em 7 doentes foi também obtido fluxo por Doppler a cores e feita a reconstrução 3D do fluxo. Foram adquiridas 25 estruturas cardíacas e foram realizadas 60 reconstruções (28 de válvulas mitrais, 14 de válvulas aórticas, 4 de próteses mitrais, 7 de próteses aórticas e 7 de CIA). Das 60 (91,6%) reconstruções, 55 foram consideradas de boa qualidade por 2 observadores independentes. As 11 válvulas/próteses mitrais e 2 CIAs reconstruídas forneceram mais informações anatômicas do que apenas o ecocardiograma bidimensional. Conclusão - A ecocardiografia 3D, pela via transesofágica, é uma técnica exeqüível, que melhora o reconhecimento de detalhes anatômicos de estruturas cardíacas, particularmente a válvula mitral e o septo interatrial.info:eu-repo/semantics/publishedVersio
Governance and sustainable regional development : the case of Santa Maria Technopark
O surgimento de um parque tecnológico pode ser uma consequência do desenvolvimento de uma região. Como também, pode ser o agente para que isso ocorra. Ao se estudar os mecanismos e contingências da gestão, é usual se deparar à conjuntura de adaptação das organizações, a fatores de cultura e sociedade e de melhor utilização de recursos naturais. De caráter exploratório-descritivo, é um estudo qualitativo, o qual tem por objetivo analisar como a governança existente no Santa Maria Tecnoparque influência para o Desenvolvimento Regional Sustentável da cidade.The creation of a technology park can be a consequence of the development of a region. It can also be the agent for this to occur. By studying the mechanisms and contingency management, it is common to come across the situation of adapting organizations, culture factors and society and better use of natural resources. In this study, the object is the Santa Maria Tecnoparque (Santa Maria, RS, Brazil), being grounded in these principles and composed of a board of academic, business and government spheres. Exploratory and descriptive, qualitative study, which aimed to analyze how existing governance in Santa Maria Tecnoparque influence for Sustainable Regional Development of the city.info:eu-repo/semantics/publishedVersio
The role of the saddle-foci on the structure of a Bykov attractor
We consider a one-parameter family ( fλ)λ 0 of symmetric vector fields on the three-dimensional sphere whose flows exhibit a heteroclinic network between two saddle-foci inside a global attracting set. More precisely, when λ = 0, there is an attracting heteroclinic cycle between the two equilibria which is made of two 1- dimensional connections together with a 2-dimensional sphere which is both the stable manifold of one saddle-focus and the unstable manifold of the other. After slightly increasing the parameter while keeping the 1-dimensional connections unaltered, the two-dimensional invariant manifolds of the equilibria become transversal, and thereby create homoclinic and heteroclinic tangles. It is known that these newborn structures are the source of a countable union of topological horseshoes, which prompt the coexistence of infinitely many sinks and saddle-type invariant sets for many values of λ. We show that, for every small enough positive parameter λ, the stable and unstable manifolds of the saddle-foci and those infinitely many horseshoes are contained in the global attracting set of fλ; moreover, the horseshoes belong to the heteroclinic class of the equilibria. In addition, we show that the set of chain-accessible points from either of the saddle-foci is chain-stable and contains the closure of the invariant manifolds of the two equilibria.info:eu-repo/semantics/publishedVersio
