Levantamento da mastofauna terrestre de médio e grande porte em remanescentes florestais na Microbacia Córrego da Cascata - Botucatu, SP

Interessada em atividades com foco conservacionista, a Ong SOS Cuesta Botucatu foi selecionada pelo programa Petrobrás Ambiental para desenvolver o Projeto Córrego da Cascata no município de Botucatu. Este projeto é uma proposta de mobilização e educação ambiental para envolver a sociedade, principalmente a população ribeirinha, na gestão e no planejamento estratégico de recuperação e conservação ambiental da Microbacia Hidrográfica do Córrego da Cascata. O foco do projeto é promover a reversão dos processos de degradação e planejar ações estratégicas integradas e participativas de manejo e de gestão para a preservação da qualidade ambiental desse córrego urbano, por meio de uma caracterização socioambiental da referida Microbacia. Em relação à caracterização ambiental, o presente estudo refere-se ao levantamento da mastofauna em fragmentos de Mata Atlântica situados na área da Microbacia. O levantamento dos mamíferos terrestres de médio e grande porte foi realizado no período de abril de 2011 a fevereiro de 2012, com a utilização de dois métodos: parcelas de areia e câmeras trap. Outros dois métodos complementares também foram utilizados na tentativa de conseguir resultados que, invariavelmente, não seriam obtidos com as metodologias acima, como entrevistas e registro de atropelamentos. O objetivo é avaliar a riqueza da mastofauna da região comparando com trabalhos anteriores feitos em fragmentos com características semelhantes aos inseridos na Microbacia do Córrego da Cascata, Botucatu, São Paulo. Foram registradas 14 espécies de mamíferos pertencentes a sete Ordens distintas, sendo duas espécies consideradas ameaçadas. Houve predominância de registros de animais generalistas/oportunistas em áreas com menor diversidade de mastofauna

Aplicação de técnicas de geoprocessamento para a avaliação da expansão urbana no municípo de Duque de Caxias (RJ) como subsídio ao monitoramento de dutos: trecho da faixa de dutos Rio de Janeiro - Belo Horizonte

Different forms of human pressure may occur in the pipeline ranges, due to the large extensions and various configurations of land use, which can pass through the pipelines. Due to the dynamics of these pressures, it is necessary to monitor temporal changes of land use and cover the surface. Under this theme, appears as extremely important to use products and techniques of remote sensing, as they allow the identification of objects of the land surface that may compromise the security and monitoring of the pipeline, and allows the extraction of information conditions on land use at different periods of time. Based on the above, this paper aims to examine in a temporal approach, the process of urban expansion in the municipality of Duque de Caxias, located on the outskirts of the metropolitan area of the state of Rio de Janeiro, as well as settlement patterns characteristic of areas that the changes occurred in the period 1987 to 2010. We used the technique of visual analysis to perform the change detection and the technique of image classification, aimed at monitoring human pressure over a stretch of track pipeline Rio de Janeiro - Belo Horizonte, located in the state of Rio de Janeiro. The stages of work involved the characterization of the study area, urban sprawl and the existing settlement patterns, through the analysis of bibliographic data. The processing of Landsat 5 images and the application of the technique of change detection were performed in three scenes for the years 1987, 1998 and 2010, while the classification process was performed on the image RapidEye for the year 2010. Can be noted an increase in urban area of approximately 22.38% and the change of land cover from natural to built. This growth is concentrated outside to the area of direct influence of the duct, occurring in the area of indirect influence of the enterprise. Regarding the settlement patterns of growth areas, it was observed that these are predominantly

Levantamento rápido de mamíferos terrestres de médio e grande porte no Parque Natural Municipal Cachoeira da Marta, Botucatu/SP

One of the most important strategies for biodiversity conservation is the establishment of protected areas, which protect areas important for the survival of several species. The park “Parque Natural Municipal Cachoeira da Marta”, located in Botucatu, São Paulo, is a unit of strictly protected area and aims to conserve the ecosystems and the biodiversity that exists in the area. The park has a management plan, but this does not include a survey of mammals present in the area, which is relevant as the group has a high degree of threat and a huge ecological importance. Thus, this study aimed to conduct a quick survey of terrestrial mammals of medium and large through the methodology of sand plots, with 25 plots distributed in five areas throughout the park. We recorded 4 orders, 6 families and 9 species (Nasua Nasua, Eira Barbara, Procyon cancrivorous, Leopardus pardalis, Leopardus sp., Dasypus novemcinctus, Tamandua tetradctyla, and Cavia aperea Myrmecophaga tridactyla). Most animals marked are generalist feeding habits, but it was also reported the presence of species more demanding regarding the quality of the habitat

Análises tectono-estratigráfica e faciológico-diagenética da coquina-reservatório Lagoa Feia, Campo de Linguado, Bacia de Campos

A tectono-stratigraphic study of bivalve coquina-reservoir of Linguado Field allowed to identify two trends of permoporosity development. The delineation of these depositional-diagenetic traps were made through structural and stratigrafic cross-sections and maps. It resulted in the identification of shelf-ramp systems (tilted to SSE), it tickens from 60 to 70 meters and ends against an antithetic fault. The main coquina is bounded by fine siliciclastic units, white clay (low Gamma Ray values) or shale (high Gamma Ray values) lithologies, influencing diagenesis of basal or top coquina limestones (cimented, non-porous). Also in the middle of coquina-reservoir the “clayer” material is also associated with cemented carbonates, with also compartimentalize the reservoir into two subzones. The coquina porosity of the subzones is taken from density-neutron logs, while induction log estimates permeabilities and fluid saturations. It’s noticed the porosity development into pairs, good one followed by a regular/poor one and vice versa. These pairs form verticals succession, pair cycles where porosity improves or decreases upwards. These two scales of pore heterogeneity impose strong layering to the reservoir, and influences fluid saturations, oil-water contacts and porosity cut-offs. In a cross-section with density and induction logs, it can be observed the porosity variation along the shelf-ramp coquina (between 3LI_0004_RJS e 3RJS_0157C_RJ), the porosity is better developed in a downdip direction in the case of the two shelf wells, and also be the three ramp wells. The southern west downdip, 3RJS_0157C_RJ well, has best porosity pairs-cycles; however, its lowest structural conditions favour water saturation. Therefore it is fundamental for reservoir fluid evaluation a cross-plot analysis of RHOB-NPHI and Induction logs

Utilização de técnicas de geoprocessamento para monitoramento de atividades de mineração ao longo de dutos: poliduto Rio de Janeiro/Minas Gerais

The transportation of oil through polyducts implies a concern related to safety and environmental impacts they may cause, especially when exposed to risks that affect their integrity. Among the various anthropogenic activities included in this scenario, mining can aggravate, increase the risks and degrade the environment. Since these polyducts go through significant extensions, remote sensing has great applicability as a tool for data acquisition. For this, change detection techniques were used to monitor mining activities in a defined study area in the state of Rio de Janeiro, along the duct ORBEL. The characterization of the study area and the mining activities were developed through bibliographical data. The satellite images processing and the application of change detection technique were performed in two scenes for the years 2002 and 2010. The growth in the mining area was about 6.67 times and it was possible to identify types of extraction involved which can represent direct risks to the pipeline

É de grande aplicação a conjuntos de dados das mais diversas áreas do conhecimento, principalmente da área biológica. Seu desenvolvimento teve um grande impulso na primeira metade do século passado. Entretanto, devido a complexidade dos cálculos matemáticos, principalmente envolvendo operações com matrizes de altas ordens, as aplicações somente se popularizaram nos dias atuais, com o desenvolvimento dos computadores e aplicativos computacionais. Técnicas estudadas: distâncias multivariadas, componentes principais, análise fatorial, correlações canônicas, análise de correspondência, teste t² de Hotelling, análise de variância multivariada (Manova), teste de normalidade multivariada, igualdade de matrizes de variâncias e covariâncias para populações multinormais

Relações públicas e o Brand Management: storytelling 2.0 na construção de relacionamentos

According to the Informational Society of the twentieth century, man develops society of the spectacle, where life becomes virtual and the individual ceases to be a spectator becoming the protagonist of wikiciberepopéia and organizations seeking to gain the attention and time of its consumers through new communication strategies. If the great epics of mankind brought mythical heroes, divine, with powers (mostly above the mortals), in the era of new technologies, the common man is in the hands the opportunity to become the hero of his own ciberepopéia. Increasingly resistant to traditional advertising, the new model of media consumer, the prosumer, the storytelling is transforming into one of the main communication tools of contemporary organizations. Offer your audience a creative and relevant content across several media platforms is a major brand positioning strategies currently used, in addition to providing the transmission of values and organizational principles in a subjective manner. Storytelling where objects are extensions of the human body (eg, the cell can be treated as an extension of the ears) is a strong indication of a technocratic society, because we can consider the new technologies as extensions of the human brain (as new store technologies, create meanings, share information through a specific language) and the individual who is on the edge of new technology ends up being excluded from certain social events. This new world tends to put an end to separation between seemingly contrary ideas, such as reality/fiction, natural/cultural and the man who emerges from this medium is not the creator, but rather, transforming what already exists. The current human evolution takes place from about half the human mind and tell stories that go beyond the media saturation that really emocionem and who have a real meaning for those who listen, to be interconnected with the socio-environmental reality of this new consumer, is a major chall...

Aforização no discurso de autoajuda

In this paper, based on Maingueneau’s (2006, 2010) thoughts on aphorisation and on the differences between aphorising and textual enunciation, we analyze some detached utterances from the self-help discourse, by highlighting some of their meaning effects and their role in such discourse. The analysis shows that the aphorising detachments support the self-help discourse enunciator in the process of guiding the interlocutors. Such aphorizing detachments allow the enunciator to give order as if he or she were enunciating the truth, which attenuates the enunciator’s authoritative character, who is supposed to give order explicitly. Moreover, such utterances activate the play between “to say and not to say,” by simulating that the self-help discourse is based on an undeniable truth, which reinforces its persuasive power.

Ordenação de constituintes em sentenças declarativas do português brasileiro

Based on Hengeveld and Mackenzie (2008)’s Functional Discourse Grammar (FDG), this article aims to analyze the natural and marked orderings of argument constituents in declarative sentences of Brazilian Portuguese taken in IBORUNA corpora. In this way, we conclude that the two natural orderings, proposed by Pezatti (1992), are determined by semantic factor, especially by semantic functions, while the marked ordering ir determined by pragmatic factor, especially by the attribution of pragmatic functions.

Uma construção de códigos BCH

Um código BCH C (respectivamente, um código BCH C 0 ) de comprimento n sobre o anel local Zp k (respectivamente, sobre o corpo Zp) é um ideal no anel Zpk [X] (Xn−1) (respectivamente, no anel Zp[X] (Xn−1) ), que ´e gerado por um polinômio mônico que divide Xn−1. Shankar [1] mostrou que as raízes de Xn−1 são as unidades do anel de Galois GR(p k , s) (respectivamente, corpo de Galois GF(p, s)) que é uma extensão do anel Zp k (respectivamente, do corpo Zp), onde s é o grau de um polinômio irredutível f(X) ∈ Zp k [X]. Neste estudo, assumimos que para si = b i , onde b é um primo e i é um inteiro não negativo tal que 0 ≤ i ≤ t, existem extensões de anéis de Galois correspondentes GR(p k , si) (respectivamente, extensões do corpo de Galois GF(p, si)) do anel Zp k (respectivamente, do corpo Zp). Assim, si = b i para i = 2 ou si = b i para i > 2. De modo análogo a [1], neste trabalho, apresentamos uma sequência de códigos BCH C0, C1, · · · , Ct−1C sobre Zp k de comprimentos n0, n1, · · · , nt−1, nt , e uma sequência de códigos BCH C 0 0 , C0 1 , · · · , C0 t−1 , C0 sobre Zp de comprimentos n0, n1, · · · , nt−1, nt , onde cada ni divide p si − 1. Palavras Chave: Anel de Galois, corpo de Galois, código BCH.

Dimensionamento de estoques de materiais elétricos em centros de distribuição

Due to the high level of service required by customers and the constant need to reduce costs, the logistics can be considered as a strategic area for a company. In particular, the order picking is responsible for most of the operating costs in a warehouse. Therefore it’s necessary to plan the materials storage in order to maximize the space available and minimize the total distance traveled to meet customer orders. For these reasons, this study aims to examine and propose a way to organize the electrical materials storage in distribution centers through a study on an electronics company in Cajamar
