Modelagem 2,5D por elementos finitos dos efeitos da topografia do terreno sobre dados obtidos com o método eletromagnético a multifrequência

Este trabalho consiste em realizar a modelagem, via elementos finitos (EF) 2,5D, do efeito da topografia do terreno sobre dados obtidos com o método eletromagnético a multi-frequência (EMMF). Este método usa como fonte uma grande espira quadrada de corrente elétrica com centenas de metros de lado, e como receptores, bobinas posicionadas na horizontal em alinhamento com o transmissor. A subsuperfície é representada por heterogeneidades bidimensionais imersas em um meio horizontalmente estratificado. A formulação, partindo das equações de Maxwell, é desenvolvida a partir da separação do campo eletromagnético em primário (campos no hospedeiro multi-estratificado) e secundário (diferença entre o campo total e o primário). O domínio discretizado é descrito por uma malha não estruturada, com elementos triangulares. Para calcular as componentes derivadas da solução de elementos finitos, em um determinado nó da malha, foi usada a média aritmética das derivadas das funções bases de EF em torno daquele nó. O código de modelagem construído permite quantificar e analisar como os gradientes topográficos influenciam as medidas dos campos eletromagnéticos gerados. A aplicação é a avaliação dessas influências sobre a componente radial do campo da espira na superfície terrestre, que é a componente empregada no método eletromagnético a multi-frequência (EMMF).

Contribuição do cadastro ambiental rural na conservação de recursos naturais nos limites de duas bacias hidrográficas amazônicas

A conversão de floresta primária para outros usos alternativos do solo vem ocorrendo aceleradamente na região amazônica. Esse processo tem ocorrido em grande parte por conta do desenvolvimento da atividade pecuarista, agricultura em larga escala e de subsistência, exploração madeireira comercial e mineração. Nesse contexto, a fim de promover a conservação dos recursos naturais, o Governo brasileiro adotou o sistema de unidades de conservação, terras indígenas e quilombolas. Além disso, foram criados instrumentos como o Cadastro Ambiental Rural – CAR objetivando mapear e monitorar as propriedades rurais quanto ao atendimento do disposto no Código Florestal brasileiro, considerando principalmente as áreas com restrição legal ao uso do solo. Assim, esta pesquisa procurou avaliar a capacidade das áreas de reserva legal em garantir a conservação dos recursos naturais em propriedades rurais, utilizando-se para tanto dados do CAR e produtos temáticos de uso e cobertura da terra oriundos de projetos institucionais federais. Para isto, foram avaliadas duas bacias amazônicas, considerando os princípios de ecologia de paisagem e com o uso de métricas de paisagem. Os resultados apontam duas áreas com características diferenciadas, sendo uma de maior capacidade de conservação de recursos e outra mais fragmentada, sendo também observadas propriedades rurais de diferentes características e importâncias na conservação de recursos dentro de cada bacia estudada.

Soil uses during the sugarcane fallow period: influence on soil chemical and physical properties and on sugarcane productivity

The planting of diversified crops during the sugarcane fallow period can improve the chemical and physical properties and increase the production potential of the soil for the next sugarcane cycle. The primary purpose of this study was to assess the influence of various soil uses during the sugarcane fallow period on soil chemical and physical properties and productivity after the first sugarcane harvest. The experiment was conducted in two areas located in Jaboticabal, São Paulo State, Brazil (21º 14' 05'' S, 48º 17' 09'' W) with two different soil types, namely: an eutroferric Red Latosol (RLe) with high-clay texture (clay content = 680 g kg-1) and an acric Red Latosol (RLa) with clayey texture (clay content = 440 g kg-1). A randomized block design with five replications and four treatments (crop sequences) was used. The crop sequences during the sugarcane fallow period were soybean/millet/soybean, soybean/sunn hemp/soybean, soybean/fallow/soybean, and soybean. Soil use was found not to affect chemical properties and sugarcane productivity of RLe or RLa. The soybean/millet/soybean sequence improved aggregation in the acric Latosol.

Multiple Ornamental Uses of Costus stenophyllus Standl. & LO Williams

Costus stenophyllus or bamboo costus, despite its high ornamental potential, is still little known in the cut flower and ornamental plant market. The bamboo costus is a spiral ginger admired for its beautiful stems that are lined with brown colored alternating bands. This costus has rather straight and upright stems. Conical red inflorescences, which resemble the head of a snake, emerge from the base of the plants. The flowers are light yellow and emerge between the red scales on the rather long-lasting, attractive inflorescences. This study was carried out to evaluate the possibility of using these species as a garden plant, cut flower and cut stem. Thus, the characterization was made based on 28 characters of the plant, the leaves, the flower stem, the flowers, as well as season blooming characteristics and flower postharvest longevity.

The contribution of multiple use forest management to small farmers' annual incomes in the Eastern Amazon

Small-scale farmers in the Brazilian Amazon collectively hold tenure over more than 12 million ha of permanent forest reserves, as required by the Forest Code. The trade-off between forest conservation and other land uses entails opportunity costs for them and for the country, which have not been sufficiently studied. We assessed the potential income generated by multiple use forest management for farmers and compared it to the income potentially derived from six other agricultural land uses. Income from the forest was from (i) logging, carried out by a logging company in partnership with farmers' associations; and (ii) harvesting the seeds of Carapa guianensis (local name andiroba) for the production of oil. We then compared the income generated by multiple-use forest management with the income from different types of agrarian systems. According to our calculations in this study, the mean annual economic benefits from multiple forest use are the same as the least productive agrarian system, but only 25% of the annual income generated by the most productive system. Although the income generated by logging may be considered low when calculated on an annual basis and compared to incomes generated by agriculture, the one-time payment after logging is significant (US$5,800 to US$33,508) and could be used to implement more intensive and productive cropping systems such as planting black pepper. The income from forest management could also be used to establish permanent fields in deforested areas for highly productive annual crops using conservation agriculture techniques. These techniques are alternatives to the traditional land use based on periodic clearing of the forest. Nevertheless, the shift in current practices towards adoption of more sustainable conservation agriculture techniques will also require the technical and legal support of the State to help small farmers apply these alternatives, which aim to integrate forest management in sustainable agricultural production systems.

Automatic Indexing and Information Visualization: A Study Based on Paraconsistent Logic

This paper reports a research to evaluate the potential and the effects of use of annotated Paraconsistent logic in automatic indexing. This logic attempts to deal with contradictions, concerned with studying and developing inconsistency-tolerant systems of logic. This logic, being flexible and containing logical states that go beyond the dichotomies yes and no, permits to advance the hypothesis that the results of indexing could be better than those obtained by traditional methods. Interactions between different disciplines, as information retrieval, automatic indexing, information visualization, and nonclassical logics were considered in this research. From the methodological point of view, an algorithm for treatment of uncertainty and imprecision, developed under the Paraconsistent logic, was used to modify the values of the weights assigned to indexing terms of the text collections. The tests were performed on an information visualization system named Projection Explorer (PEx), created at Institute of Mathematics and Computer Science (ICMC - USP Sao Carlos), with available source code. PEx uses traditional vector space model to represent documents of a collection. The results were evaluated by criteria built in the information visualization system itself, and demonstrated measurable gains in the quality of the displays, confirming the hypothesis that the use of the para-analyser under the conditions of the experiment has the ability to generate more effective clusters of similar documents. This is a point that draws attention, since the constitution of more significant clusters can be used to enhance information indexing and retrieval. It can be argued that the adoption of non-dichotomous (non-exclusive) parameters provides new possibilities to relate similar information.

A BCH code and a sequence of cyclic codes

This study establishes that for a given binary BCH code C0 n of length n generated by a polynomial g(x) ∈ F2[x] of degree r there exists a family of binary cyclic codes {Cm 2m−1(n+1)n}m≥1 such that for each m ≥ 1, the binary cyclic code Cm 2m−1(n+1)n has length 2m−1(n + 1)n and is generated by a generalized polynomial g(x 1 2m ) ∈ F2[x, 1 2m Z≥0] of degree 2mr. Furthermore, C0 n is embedded in Cm 2m−1(n+1)n and Cm 2m−1(n+1)n is embedded in Cm+1 2m(n+1)n for each m ≥ 1. By a newly proposed algorithm, codewords of the binary BCH code C0 n can be transmitted with high code rate and decoded by the decoder of any member of the family {Cm 2m−1(n+1)n}m≥1 of binary cyclic codes, having the same code rate.
