Análise geoambiental da plataforma continental Rasa Equatorial, por meio de sensoriamento remoto e dados sedimentológicos: parrachos de Rio do Fogo-RN, Brasil

In the shallow continental shelf in Northeastern Rio Grande do Norte - Brazil, important underwater geomorphological features can be found 6km from the coastline. They are coral reefs, locally known as “parrachos”. The present study aims to characterize and analyze the geomorphological feature as well as the ones of the benthic surface, and the distribution of biogenic sediments found in parrachos at Rio do Fogo and associated shallow platforms, by using remote sensing products and in situ data collections. This was made possible due to sedimentological, bathymetric and geomorphological maps elaborated from composite bands of images from the satellite sensors ETM+/Landsat-7, OLI/Landsat-8, MS/GeoEye and PAN/WordView-1, and analysis of bottom sediments samples. These maps were analyzed, integrally interpreted and validated in fieldwork, thus permitting the generation of a new geomorphological zoning of the shallow shelf in study and a geoenvironmental map of the Parrachos in Rio do Fogo. The images used were subject to Digital Image Processing techniques. All obtained data and information were stored in a Geographic Information System (GIS) and can become available to the scientific community. This shallow platform has a carbonate bottom composed mostly by algae. Collected and analyzed sediment samples can be classified as biogenic carbonatic sands, as they are composed 75% by calcareous algae, according to the found samples. The most abundant classes are green algae, red algae, nonbiogenic sediments (mineral grains), ancient algae and molluscs. At the parrachos the following was mapped: Barreta Channel, intertidal reefs, submerged reefs, the spur and grooves, the pools, the sandy bank, the bank of algae, sea grass, submerged roads and Rio do Fogo Channel. This work presents new information about geomorphology and evolution in the study area, and will be guiding future decision making in the handling and environmental management of the region

Estudo do comportamento da sinterização de compactos de cavacos de um aço SAE 1050 obtidos sob alta pressão

From an economic standpoint, the powder metallurgy (P/M) is a technique widely used for the production of small parts. It is possible, through the P/M and prior comminution of solid waste such as ferrous chips, produce highly dense sintered parts and of interest to the automotive, electronics and aerospace industries. However, without prior comminution the chip, the production of bodies with a density equal to theoretical density by conventional sintering techniques require the use of additives or significantly higher temperatures than 1250ºC. An alternative route to the production of sintered bodies with high density compaction from ferrous chips (≤ 850 microns) and solid phase sintering is a compression technique under high pressure (HP). In this work, different compaction pressures to produce a sintered chip of SAE 1050 carbon steel were used. Specifically, the objective was to investigate them, the effect of high pressure compression in the behavior of densification of the sintered samples. Therefore, samples of the chips from the SAE 1050 carbon steel were uniaxially cold compacted at 500 and 2000 MPa, respectively. The green compacts obtained were sintered under carbon atmosphere at 1100 and 1200°C for 90 minutes. The heating rate used was 20°C/min. The starting materials and the sintered bodies were characterized by optical microscopy, SEM, XRD, density measurements (geometric: mass/volume, and pycnometry) and microhardness measurements Vickers and Rockwell hardness. The results showed that the compact produced under 2000 MPa presented relative density values between 93% and 100% of theoretical density and microhardness between 150 HV and 180 HV, respectively. In contrast, compressed under 500 MPa showed a very heterogeneous microstructure, density value below 80% of theoretical density and structural conditions of inadequate specimens for carrying out the hardness and microhardness measurements. The results indicate that use of the high pressure of ferrous chips compression is a promising route to improve the sinterability conditions of this type of material, because in addition to promoting greater compression of the starting material, the external tension acts together with surface tension, functioning as the motive power for sintering process. Additionally, extremely high pressures allow plastic deformation of the material, providing an intimate and extended contact of the particles and eliminating cracks and pores. This tends to reduce the time and / or temperature required for good sintering, avoiding excessive grain growth without the use of additives. Moreover, higher pressures lead to fracture the grains in fragile or ductile materials highly hardened, which provides a starting powder for sintering, thinner, without the risk of contamination present when previous methods are used comminution of the powder.

When petro-capitalism comes knocking: community interpretations and responses to the Gros Morne fracking controversy

With the depletion of conventional oil and gas sources, the world is turning to what Urry terms “tough oil,” such as oil from the Alberta oil sands and Arctic. Fracking is a prominent example of this. Situated within an environmental justice framework, I analyze community interpretations and responses to proposed fracking development near Gros Morne National Park, Newfoundland, Canada. Based on data generated from interviews, field observations and content analysis of texts, my findings suggest that how residents view rural place is highly significant in influencing supportive or oppositional positions on fracking. Proponents picture place as a resource extraction landscape, whereas opponents understand place as a restorative landscape for leisure/tourism activities. Through debates about fracking, place is contested and re-imagined. In many ways, fracking is a struggle over who has the power to define the meanings and characteristics of rural community in an era of tough oil and significant rural change.

Influência das áreas verdes no microclima local: um estudo do conjunto habitacional Ponta Negra, Natal/RN

Owing to na intense process of urban development, urban uneasiness and discomfort in the daily life of populations have nowadays, especially in the big cities, become increasingly ordinary issues. Population density, degeneration of central areas and pollution are some of the environmental stressors the urban man is subjected to. The existence of open areas in the urban network contributes to a better movement of the air and transforms salubrity conditions. Yet, it has been noticed that parks and squares are disappearing from the heart of the city districts. In their place there are either unused plots of land where garbage has been dumped or nearly all-paved squares with meager or no vegetation at all. Such areas, when handled properly, play an important role in the city because in addition to being zones for rendering a mild climate they perform social, cultural and hygienic functions. Aiming at demonstrating that proper handling of green areas can favorably influence the local microclimate, we have attempted to develop analysis from the point of view of bioclimatizing attributes of urban form and their relationship to the local microclimate found in the eight open areas located in the Ponta Negra Housing Complex in the city of Natal/RN

Sistema de áreas verdes de la zona urbana del Cantón Cuenca

Con la desaparición de los espacios verdes de la Ciudad, surge la necesidad de plantear una propuesta detonante de una cultura de conservación que afronte el principal problema de las áreas verdes ya existentes, su fragmentación. De esto nace la idea de plantear un Sistema, un funcionamiento conjunto de varios elementos conformantes de un todo, que proporcione una visión global de estos espacios y permita el planteamiento de nuevas zonas de reserva que abastezcan a largo plazo la demanda de la población. El trabajo comprende, dentro de una visión macro, una importante compilación de datos, que se ha logrado mediante el inventario, análisis de muestreos, levantamientos fotográficos, análisis visual paisajístico de las áreas verdes y el manejo de datos técnicos e indicadores.

Produtividade e qualidade de grãos de híbridos de canola cultivados em diferentes épocas no sudoeste do Paraná

Canola is the third most important oilseed in global agribusiness. Used in several market segments, its cultivation in Brazil began in the 70s The growth of canola cultivation aimed at producing beans intended for oil extraction can provide high economic efficiency of farms, the choice of the time correct for sowing is essential for this purpose is achieved. Objective of this study was to evaluate the performance of canola hybrids (Hyola 61, Hyola 76, Hyola 411, 433 and Hyola Hyola 571) evaluated in six sowing dates started on 09/03 (1 time) 06/04 (2 times ), 04/05 (3 times), 01/06 (4 times), 29/06 (5 times) and 26/07 (6 times). The experiments were conducted at the Experimental Station of the Federal Technological University of Paraná - UTFPR, Campus Dois Vizinhos. The field experiment was arranged in a randomized block design with split plots in three replications in two years (2013 and 2014 crop). Evaluated the agronomic characteristics as the number of days between emergence and flowering, number of days duration of flowering, number of days between emergency and physiological maturity, average plant height, plant lodging, grain yield, weight a thousand grains, crude protein content in grain and ether extract in the grains. There were significant differences between the effects of the six sowing dates in all variables, including hybrids and years. The study was able to show that it is possible to grow canola in the Southwest of Paraná. Being the first times more responsive sowing and Hyola 411 and Hyola 433 hybrid proved the most suitable among the variables observed.

Efeitos diretos e indiretos de parâmetros dos semivariogramas referentes aos atributos químicos do solo sobre a produtividade de grãos de soja

In order to add value to soybens crops, and hence the marketing, medium and large producers have been using precision agriculture techniques (PA), as the Remote Sensing, Geographic Information Systems (GIS) and positioning satellite, to assist the management of crops. Thus, given the economic relevance of that culture to the southwest of Paraná State and Brazil, scientific studies to increase their productivity and profitability are of main importance. The objective of this study was to evaluate the correlation between the chemical soil properties and soybean yield for each estimated parameter of semivariogram (range, nugget and level effect), and the deployment of these correlations in direct and indirect effects, aiming to improve the mapping process of spatial variability of soil chemical properties for use in PA. The hypothesis is that not all attributes of soil used to estimate the semivariogram parameters has a direct effect on productivity, and that even in groups of plants within a larger area it is possible to estimate the parameters of the semivariograms. The experiment was conducted in a commercial area of 19.7 ha, located in the city of Pato Branco - PR, central geographic coordinates 26º 11 '35 "South, 52 43' 05" West longitude, and average altitude of 780 m. The area is planted with soybeans for over 30 years, currently being adopted to cultivate Brasmax Target RR - Don Mario 5.9i, with row spacing of 0.50 m and 13 plants m-1, totaling 260,000 plants ha-1. For georeferencing of the area of study and sampling points was used a couple of topographic ProMarkTM3 receptors, making a relative positioning to obtain the georeferenced coordinates. To collect data (chemical analyzes of soil and crop yield) were sampled 10 blocks in the experimental area, each with an area of 20 m2 (20 meters long x 1 meter wide) containing two spaced adjacent rows of 0.5 m. Each block was divided into 20 portions of 1 m2, and from each were collected four subsamples at a distance of 0.5 m in relation to the lines of blocks, making up a sample depth for 0-10 cm a sample to 10-20 cm for each plot, totaling 200 samples for each depth. The soybean crop was performed on the blocks depending on maturity, and in each block was considered a bundle at each meter. In the data analysis, it was performed a diagnosis of multicollinearity, and subsequently a path analysis of the main variables according to the explanatory variables (range of chemical attributes: pH, K, P, Ca, etc.). The results obtained by the path analysis of the parameters of the semivariogram of soil chemical properties, indicated that only the Fe, Mg, Mn, organic matter (OM), P and Saturation by bases (SB) exerted direct and indirect effects on soybean productivity, although they have not presented spatial variability, indicating that the distribution of blocks in the area was unable to identify the spatial dependence of these elements, making it impossible to draw up maps of the chemical attributes for use in PA.

Contributos para o planeamento da rede de espaços verdes públicos, de recreio infantil e recreio sénior, para a cidade de Coimbra

Os espaços verdes públicos de recreio infantil e sénior são indispensáveis para a qualidade do ambiente e da vida urbana, pela sua importância e pelos múltiplos benefícios que lhe estão associados. A criação deste tipo de espaços deve ocorrer de modo concertado com o crescimento das cidades. Neste sentido, as politicas de planeamento urbano devem dar resposta a uma rede coesa deste tipo de espaços na cidade concebendo-os de modo a que sejam acessíveis a toda a população. O presente trabalho apresenta uma metodologia de planeamento de uma rede de espaços verdes públicos de recreio infantil e recreio sénior para a cidade de Coimbra. A metodologia é apoiada numa primeira fase em fichas de levantamento e numa segunda fase recorre-se à aplicação dos Sistemas de Informação Geográfica (SIG); ABSTRACT: Public green spaces for the recreation of children and senior are essential for the quality of the environment and urban life, given their importance and the multiple benefits associated with them. The creation of such spaces must occur in parallel with the growth of the cities. Therefore, urban planning policies must meet a cohesive network of this type of spaces in the city, designing them to be accessible to the entire population. This work presents a methodology for the planning of a network of public green spaces for the recreation of children and seniors for the city of Coimbra. The methodology is supported initially in survey forms and a second phase refers to the application of Geographic information Systems (GIS).

Produção de biomassa e composição química de adubos verdes cultivados no Vale do Ribeira

The contribution of green manure to soil improvement and crop production depends primarily on biomass production and its chemical composition, which vary depending on the species, region and growing season. The aim of this research was to evaluate the chemical composition of biomass produced by green manures in Vale do Ribeira, São Paulo, Brazil. In order to develop this research, was carried an experiment in Pariquera-Acu, in 2006/2007, in completely randomized blocks design with four treatments (three green manure and spontaneous vegetation) and five replications. At 30, 60, 90 and 120 after sowing samples were collected in 1m(2) of the shoots and determined fresh and dry, and chemical composition biomass. Sunhemp, pigeon pea and mucuna produced, in decreasing order, the largest quantities of biomass and were more efficient than the spontaneous vegetation. The biomass produced by green manure had higher quality than that produced by spontaneous vegetation. Sunhemp and pigeon pea have a higher proportion of dry matter in stems which have low N, high C/N and L/N ratio, variables indicating slow decomposition of residues. The analysis of dry matter partitioned to better indication of the chemical composition of the residues and the prevision of the availability of nutrients in the soil.

Avaliação da disponibilidade de espaços verdes públicos no contexto urbano e a sua relação com a perceção dos residentes. Um estudo para a cidade de Bragança

Os espaços verdes públicos urbanos são muito importantes no contexto urbano. Influenciam de diversas formas na qualidade de vida das populações, proporcionando benefícios ambientais, sociais e econômicos. A fim de avaliar a disponibilidade destes espaços na cidade de Bragança, foram realizadas análises utilizando indicadores, com apoio dos software ArcGIS 9.3 e QGis 2.14.0-Essen, que permitiram avaliar a oferta destes espaços nas suas diferentes tipologias e categorias dimensionais. Para o efeito foram aplicados os indicadores: Percentagem de espaços verdes, Espaços verdes per capita, Distância média, Índice de Área Verde por Área de Implantação e Índice de Área Verde por Área Coberta. Posteriormente, procedeu-se à aplicação de inquéritos a fim de avaliar as perceções e atitudes de uma amostra da população de Bragança, realizando análises descritivas e estatísticas, com recurso ao software SPSS17, buscando descrever a atual relação com os espaços verdes e usando testes não paramétricos para identificar diferenças entre subgrupos da amostra, numa análise centrada em dois níveis: a escala urbana e a escala de Bairro. Procurando avaliar possíveis alterações futuras, foram testados cenários realistas, um correspondendo à introdução de espaços verdes em terrenos na posse da Autarquia e outro considerando a ampliação das áreas verdes previstas no Plano de Urbanização de Bragança de 2010. Os Resultados permitiram identificar diferenças relevantes na oferta de espaços verdes da cidade. Aplicando os indicadores foi possível verificar que existe a concentração de espaços verdes de maior dimensão na zona central da cidade, denotando um claro desequilíbrio na introdução de novos espaços em zonas de expansão urbana. Os inquéritos aplicados possibilitaram constatar que os inquiridos que possuem maior disponibilidade de espaços verdes em seu bairro de residência apresentam respostas mais satisfatórias em relação a acessibilidade e a aparência visual e paisagística dos bairros. Da análise de cenários resulta que com a implantação de novos espaços verdes, para as duas análises, ocorreria uma melhoria da oferta e distribuição dos espaços verdes na cidade permitindo um maior reequilíbrio face à concentração na zona central, melhorando a acessibilidade para toda a população.
