As stated in Aitchison (1986), a proper study of relative variation in a compositional data set should be based on logratios, and dealing with logratios excludes dealing with zeros. Nevertheless, it is clear that zero observations might be present in real data sets, either because the corresponding part is completely absent –essential zeros– or because it is below detection limit –rounded zeros. Because the second kind of zeros is usually understood as “a trace too small to measure”, it seems reasonable to replace them by a suitable small value, and this has been the traditional approach. As stated, e.g. by Tauber (1999) and by Martín-Fernández, Barceló-Vidal, and Pawlowsky-Glahn (2000), the principal problem in compositional data analysis is related to rounded zeros. One should be careful to use a replacement strategy that does not seriously distort the general structure of the data. In particular, the covariance structure of the involved parts –and thus the metric properties– should be preserved, as otherwise further analysis on subpopulations could be misleading. Following this point of view, a non-parametric imputation method is introduced in Martín-Fernández, Barceló-Vidal, and Pawlowsky-Glahn (2000). This method is analyzed in depth by Martín-Fernández, Barceló-Vidal, and Pawlowsky-Glahn (2003) where it is shown that the theoretical drawbacks of the additive zero replacement method proposed in Aitchison (1986) can be overcome using a new multiplicative approach on the non-zero parts of a composition. The new approach has reasonable properties from a compositional point of view. In particular, it is “natural” in the sense that it recovers the “true” composition if replacement values are identical to the missing values, and it is coherent with the basic operations on the simplex. This coherence implies that the covariance structure of subcompositions with no zeros is preserved. As a generalization of the multiplicative replacement, in the same paper a substitution method for missing values on compositional data sets is introduced

The binding of NO to iron is involved in the biological function of many heme proteins. Contrary to ligands like CO and O-2, which only bind to ferrous (Fe-II) iron, NO binds to both ferrous and ferric (Fe-II) iron. In a particular protein, the natural oxidation state can therefore be expected to be tailored to the required function. Herein, we present an ob initio potential-energy surface for ferric iron interacting with NO. This potential-energy surface exhibits three minima corresponding to eta'-NO coordination (the global minimum), eta(1)-ON coordination and eta(2) coordination. This contrasts with the potential-energy surface for Fe-II-NO, which ex- hibits only two minima (the eta(2) coordination mode for Fe-II is a transition state, not a minimum). In addition, the binding energies of NO are substantially larger for Fe-III than for Fe-II. We have performed molecular dynamics simulations for NO bound to ferric myoglobin (Mb(III)) and compare these with results obtained for Mb(II). Over the duration of our simulations (1.5 ns), all three binding modes are found to be stable at 200 K and transiently stable at 300 K, with eventual transformation to the eta(1)-NO global-minimum conformation. We discuss the implication of these results related to studies of rebinding processes in myoglobin.

Numa época em que as tendências internacionais do Turismo se estão a implementar, no sentido da procura de produtos turísticos compósitos diversificados, integrando componentes associadas à cultura, ao património histórico, arquitectónico e monumental e património natural, o Núcleo Histórico do Monte, inteirando todas estas componentes, apresenta-se como um destino de eleição do turista que visita a Ilha da Madeira. Apresentando inúmeras potencialidades, como sejam a riqueza do seu património histórico, cultural e natural e as estruturas de lazer e recreio, distintas na Região Autónoma da Madeira, este destino, apresenta ainda algumas debilidades, nomeadamente a inexistência de alguns serviços fundamentais para o bom exercício da actividade turística e a inexistência de uma promoção conjunta dos locais, tornando a visita consideravelmente dispendiosa. O propósito deste trabalho, visa o estudo de viabilização para a criação de uma Associação para o Desenvolvimento do Destino Turístico Monte, possibilitando melhorias significativas no Núcleo Histórico, em termos de recuperação do seu património edificado; da disponibilização de informação; no estímulo ao comércio, desenvolvendo produtos de merchandising diferenciados; na elaboração de estratégias de promoção conjuntas; na realização de actividades de animação e formação; e na realização de acções de carácter pedagógico, com vista a aproximar a população local ao seu património, fomentando o gosto por iniciativas culturais, bem como, apelando para a importância da salvaguarda do património histórico, cultural e natural, não só como factor de identidade regional, mas também, como instrumento indispensável para o desenvolvimento sustentado da Região Autónoma da Madeira.

Geological and Geomorphological Sites of the Towns of Acari, Carnaúba dos Dantas and Currais Novos, Seridó Region of the Rio Grande do Norte, northeastern Brazil, consist s of a study about geological, geomorphological, mineralogical, palaeontological and archaeological features of the study area, aiming the identification of sites that presents scientific, historical, cultural, economic and ecological excellent importance, and that they deserve to receive special protection for its maintenance for the gifts and future generations. It was developed according with methods adopted for the Brazilian Commitee of Geological and Paleontological Sites SIGEP/UNESCO and by Initiati ve of Sofia for the Preservation of the Mineral Diversity of the Planet, objectifying the description of the main sites, the its environmental problematic and proposal of protectionistic measures. Seven sites with features and typical structures had been identified that they deserve to be aim of protection. In the Acari town, three sites had been identified: geological -geomorphologicalarchaeological site Barra of the Carnaúba; geological-geomorphological site of the Gargalheiras; and geological-geomorphological site Bico of Arara. In Carnaúba of the Dantas, the geomorphological complex river of the Bojo that possesss canyons and deep throats, with rocky-arts registers of the three great rocky-arts traditions of northeast: Northeast Seridó Sub-tradition, Wasteland and Itaquatiara. In the Currais Novos town, 3 sites had been also identified: geomorphological site Canyon of the Apertados; geomorphological-archaeological-palaeontological complex of the Totoró; e, geologicalmineralogical site Brejuí. Because to the environmental problematic that it involves each one of the identified sites, it is proposed, as a guarantee of protection to these sites, its economic exploitation with the ecogeotouristic activity, that it aims at to the integration of the community in programs of environmental education and others, besides providing to the generation of job and income for the towns. Finally, a series of measures is suggested that they aim at to the efectivation of the activity and to the protection of the sites that they can be classified as natural heritage, in accordance with the denomination of UNESCO, in its program World Natural Heritage

Diferentes autores concordam que os trabalhadores rurais brasileiros passam por grandes dificuldades relacionadas aos problemas socioambientais e muitas vezes, por não disporem de informações adequadas para o desenvolvimento de suas atividades, são potenciais responsáveis pela depredação do patrimônio natural da área ocupada. Na busca por uma formação diferenciada, o Movimento dos Trabalhadores Sem-Terra (MST) investiu no Curso de Licenciatura Plena em Pedagogia para Educadores (as) da Reforma Agrária, denominado Pedagogia da Terra (CPT), implementado pela Universidade Federal do Pará (UFPA), no período de fevereiro de 2001 a maio de 2005, em parceria com o Instituto Nacional de Colonização e Reforma Agrária (INCRA) e o Programa Nacional de Educação na Reforma Agrária (PRONERA). Esta pesquisa teve os seguintes objetivos: 1) Estudar os princípios que embasam o Curso de Pedagogia da Terra através de documentos referenciais; 2) Averiguar a percepção dos alunos-professores referente à proposta educativa do Curso e 3) Caracterizar a práxis dos egressos em Educação Ambiental. O estudo enveredou pela pesquisa qualitativa na abordagem investigativa - narrativa. Inicialmente realizei pesquisa documental que serviu de base para formulação de uma entrevista semi-estruturada, direcionada a cinco alunos professores do CPT, para tanto, visitei dois assentamento e um acampamento. Para a sistematização e análise, o material foi transcrito literalmente, procurando identificar os temas relevantes e recorrentes, assim como comunalidades e contradições, visando estabelecer categorias de análises. Para aprofundar a questão em foco, busquei a técnica da triangulação de dados e teorias como mais uma forma de interpretação das informações coletadas. Cheguei a conclusão que, a proposta do Curso, apesar de algumas dificuldades, foi bem aceita pelos educandos, sendo avaliado positivamente como um processo rico de aprendizagem e formação que possibilitou a reflexão, a busca da melhoria da qualidade de vida, por meio da inclusão social e do respeito à especificidade da Educação do Campo e a diversidade dos seus sujeitos. Quanto a EA percebo que os alunos-professores têm percepção da importância desta no dia-a-dia da escola e a destacam como: 1) meio para a mudança de mentalidade, como 2) forma de regular a intervenção do homem no ambiente, considerando a intencionalidade desta. Acredito que esta pesquisa contribuiu para revelar a importância de cursos como o CPT em relação ao aprimoramento e a ampliação de conhecimentos em EA, contextualizados em realidades específicas como a vivenciada nos assentamentos/acampamentos paraenses.

Cardoso Island, settled in the south of paulista region, is characterized by its ecological importance due to the great biodiversity of Mata Atlântica and for accommodating several kinds of ecosystems as mangroves, which were considered by UNESCO as human natural ownership. The mangroves are among the most important marine ecosystems, known as warranty of biological productivity and diversity and supply of food and economical resources to the local population. Although the island has been transformed in a state park for preservation, it hasn’t become free from environmental impacts made by antropical activities. This way it was proposed a rebuilt of an evolutionary process in the region, having as an objective to subsidize programs of environmental conservation and planning , aiming to a sustainable development. For this it was used a isobasis methodological analyses where by the drainage channels and its confluences makes relative maps to the different base levels represented by the isobasis, characterizing itself by an attempt to rebuilt the preterit local landscape. There were elaborated eight maps referring to four orders of confluences met in the region of Cardoso Island and round it where you can conclude it is about an appropriate methodology to rebuilt preterits environments that specially aim to actions of environmental planning and conservation.

The brazilian legislation has sufored changes by the law no 1876/99, without the scientific community consultation, causing grave consequences for the country natural patrimony. The goal of this research is to investigate what the professors and students community of a São Paulo University know about the theme, as much as a rural and urban portion of persons; what they consider important and which atributes are taken in consideration. By the elaboration of closed questionnaires, qualitative and quantitative datas were collected, organized and analysed. The datas showed a low schooling by the countrified people, which reflected the low forest law knowledge. The distance between the university and society was also noticed, which indicates the lack of extension activities, ethical commitment against knowledge, technology and the sustainable development of the country. Due to, highlight the importance of extension activities towards the university, community and a knowledge future of all

This assignment intents to analyze the recover and the research of the cultural legacy identity of Vicentina Aranha Sanatorium to the inhabitants of the city of São José dos Campos-SP. That initiative becomes present through the importancy of the sanatorium to the public health of Vale do Paraíba in the decades between 30 and 70, of the 20th century. Nowadays this place refuges a park, presenting a reexamination of its space, with the possibility of the leisure practice, entertaining and tourism. The Vicentina Aranha Sanatorium Park presents itself conserving a landscape that is able of being inserted in a continuum past-present resignifying ways of appropriation and use. The word patrimony has many meanings and it‟s commonly associated to the set of goods that someone, the society or an entity owns. Transporting in a determinate territory, the patrimony starts to be a set of goods that are in its limits of administrative competency. (BARRETO, 2000). More than this, the cultural-historical patrimony guard a relation of belonging between it and the entity that has it. The Vicentina Aranha Sanatorium was inaugurated in 1924, with the project of the architect, Ramos de Azevedo, constituting an architectural ensemble placed under governmental trust as a historical and cultural patrimony of the state in 2001. It has a grove with centenary vegetal species like: MOGNO, PEROBA ROSA, JEQUITIBÁ and JACARANDA, constituting also a natural patrimony important for the city. There are projects like “Leitura no Bosque” and it‟s visited by the local population. Today the city seeks a new identity for that place transforming it in the center of industrial and technologic study
