Item Diagnóstico da arborização de vias públicas no entorno dos reservatórios elevados de água no município de Paulista-PE(2018) Silva, Satyro Barbosa da; Duarte, Simone Mirtes Araújo; Silva, Hernande Pereira da; http://lattes.cnpq.br/1800835100486343; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/6865576903260120The benefits that urban tree-planting provides to communities where there are established trees, such as providing shade for pedestrians, physical soil stabilization, reducing the impact of rain, avoiding heat islands and biological deserts, provide scenic beauty and psychological well-being are indisputable, barring or channeling the wind and dampening the sound. However, there are many difficulties encountered in establishing an afforestation project in consolidated urban communities, mainly due to lack of planning, adequate urban furniture, telephony, sanitation and electrical equipment. Trees are sometimes considered as negative points of conflict, being blamed for destroying sidewalks, disrupting electrical wiring, breaking pipes and causing accidents by falling branches or falling over. Based on the principle that the more trees, the better the thermal sensation and the less the need to use treated water in the search for this balance, this work proposes an afforestation project around the five reservoirs administered by Companhia Pernambucana de Saneamento – COMPESA, as a way to benefit communities, not only with sanitation, but also with afforestation. For that, aerial-photogrammetric images of 0.50 x 0.50 m resolution were used, the census of the trees was carried out in the surroundings of the five reservoirs used in the study of the city of Paulista, from which several indices were obtained that allowed to evaluate and elaborate an afforestation plan in the roads that offered the physical conditions to do so. A total of 1,222 individuals were collected, distributed in 19 botanical families and 43 species, in which 86.7% of the species are exotic to the Brazilian flora and 13.3% are native. The most frequent species around the reservoirs were: Ficus benjamina L. (29.7%), Roystonea oleracea (Jacq.) O.F. Cook. (11.3%) and Terminalia catappa L. (10.8%). Based on current standards and similar literature, localities, quantity, adequate distance and species to be planted on the public, road were proposed in order to bring back the well-being that the population needs, totaling 415 trees distributed in 15 species of native origin. The study also shows the need for public intervention through campaigns to raise awareness of the importance of trees and especially in the structuring of roads that lack proper attention.Item Delimitação e caracterização morfométrica da sub-bacia do Rio Gurjaú com o uso de geotecnologias(2018) Silva, Júlia Andresa Freitas da; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/5132661779293685The study of the characteristics of a river basin allows one to understand its dynamics and to carry out an adequate management of its resources. With this in view, the present work aimed to characterize morphometrically the sub-basin of the Gurjaú River, in the Metropolitan Region of Recife -PE, through geotechnologies. In this study, a shapefile of the municipalities of Pernambuco was used, which assisted as a visual reference to locate the water course, and an SRTM image of spatial resolution of 30 mx 30 m, referring to the study area, provided by the National Institute of Space Research (INPE). Using Google Earth Pro, the Gurjaú River was identified. The image was imported into the free software Spring 5.5.4 ̧ where the isolines, the water flow directionmatrix and the flow matrix accumulated in each cell were generated, which were used to delimit the sub-basin. The area and perimeter of the basin were measured and the water flowswere vectored. The altitude was rated 30 by 30 meters. The gradient grid was generated, and the maps of hypsometry and slope were elaborated. The following morphometric parameters were calculated: compaction coefficient (Kc), circularity index (Ic), shape factor (Kf), elongation ratio (Re), drainage network, drainage hierarchy, drainage density (Dd) (Dh), torrentiality coefficient (Ct), maintenance coefficient (Cm), roughness index (HD) and relief ratio (Rr). The minimum altitude found in the sub-basin was 0 m, and the maximum altitude was 370 m. The most representative altitude class along the sub-basin was between 90 and 120 m, while the least representative was between 360 and 390 m. The minimum slope was 0% and the maximum found was 181.57%. The relief of the region is mostly wavy, presenting between 8% and 20% of slope. The area found was 148,115 km², the perimeter was 68,948 km and the axial length of the sub-basin was 22,723 km. The values obtained for the morphometric characteristics were: Kc = 1.586; Ic =, 392; Kf = 0.287; RL = 0.604; total length of watercourses = 110,226 km; hierarchy of channels = 4th order; Dd = 0.744 km.-2; Dh = 0.317; Ct = 0.235; Cm = 1344.09 m².m-1; HD = 0.277; Rf = 16.28. It was possible to notice that the sub-basin of the Gurjaú River has an elongated form, with slopes not very steep, and therefore is not subject to floods.Item Monitoramento tecnológico das espécies arbóreas nativas do Brasil(2018) Ribeiro, Isabele Arruda; Berger, Rute; http://lattes.cnpq.br/5395827385005105; http://lattes.cnpq.br/1080675525400531Brazil is a privileged country in geographical location and natural resources, is recognized worldwide for the high productivity of its planted areas and has many universities with innovative research, but on the other hand, it makes few uses of its biodiversity and its species are being studied and reverted in products by other countries. In this context, since the sectors of technological innovation and natural resources has great potential for Brazil, the objective of this work was to analyze the use of native tree species in technological innovations through the national and international patent system. From this, it was possible to: identify the most used species in Brazilian patents, its purpose, the endemism of these species and their distribution by phytogeographic domain; the number of Green Patents; the percentage of Universities, Individuals and Companies, and their source; and compare the national and international scenario. First, the search terms were organized in a table and used for technological monitoring in the INPI patent base. The collected data were analyzed, and once the used species were identified, the site Flora do Brasil was consulted for analyzes of the spatial distribution of these trees. Finally, based on the national results, a search was made on the main international basis. Only one of the documents was considered a Green Patent; 23 states deposited documents that use native tree species, with Sao Paulo being the largest depositor; despite having the fewest species, the Pampa and the Pantanal were the phytogeographic domains that used the most their species in the form of products and processes. Universities are the largest depositors in Brazil, and 16% of Brazilian deposits came from internationals. The main purpose of use was for medicinal preparations and the most cited species was Anacardiumoccidentale L. The species Theobroma grandiflorum (Willd. Ex Spreng.) K.Schum., is the endemic species that was cited in most patents deposited in Brazil, and was mentioned in 15 documents. When surveyed on the international basis, this species has 28 results from 21 countries, however, when the restriction of citing the species only on the document's front page is removed, it goesto 444 patents, which is almost the number of all patents with native tree species found in Brazil.Item Produtividade e custos do corte de eucalipto com Feller-Buncher em função de angulações de derrubada(2018) Soares, Jean Gueiros; Hakamada, Rodrigo Eiji; http://lattes.cnpq.br/4186459700983170; http://lattes.cnpq.br/6211276690009951The present work aimed to perform the technical and economic analysis of the feller buncher operation in three different subsystems in a eucalyptus plantation through a study of time and motion and calculation of operating and production costs using the accounting method. The study was carried out in a forest harvesting area at Monte Alegre farm that belongs to the company Klabin S.A., and is located in Telêmaco Borba, state of Paraná. The subsystems 17 ° (T1), 45 ° (T2) and 90 ° (T3) were evaluated, differing one from another by the angle at which the wood bunchers newly cut by the equipment are arranged in the soil for later skidder operation. The equipment used for the analysis was a feller buncher of the brand Tigercat, model L870 C, with 3679 hours worked, equipped with engine Cummins QSL9 Tier III (diesel) of 224 kW/300 hp of nominal power at 1800 rpm and head of Tigercat cutter model ST5702. The results showed that the greatest element of the operational cycle found in the study was the cut/accumulation, which occupied about 70% of the effective working time of the equipment. The mechanical availability, degree of utilization and operational efficiency found were 93,85 and 77% respectively. The effective yield was 138.68, 138.91 and 149.00 m³ he-1 respectively in treatments 1 (17 °), 2 (45 °) and 3 (90 °). The fuel consumption of the equipment was 44.78 L he-1, reaching a specific consumption of 169.92 g kw-1 he-1 and an energy yield of 1.22, 1.22 and 1.14 g kw-1 m³ respectively for the 17 °, 45 ° and 90 ° subsystems. The operating cost of the feller buncher was R$ 371.68 per effective hour of work, making, under the conditions evaluated, a cost of production of R$ 2.68, R$ 2.68 and R$ 2.49 per cubic meter for the 17 °, 45 ° and 90 ° subsystems respectively. The 90° angle tipping subsystem was about 7% more productive, making the cost of production cheaper in this treatment, reinforcing that, if feasible, it is important that this subsystem is used.Item Regeneração natural do Parque Ecológico do Gravatá, no município de Eunápolis-BA(2018) Silva, Caio Victor Santos; Marangon, Luiz Carlos; Almeida, Danilo Sette de; http://lattes.cnpq.br/7418157304387390; http://lattes.cnpq.br/6130999923981614; http://lattes.cnpq.br/7488530294972996
