Item Descrição do método construtivo e das espécies mais utilizadas na construção naval tradicional no litoral sul pernambucano(2019-12-13) Vasconcelos, Teylor Moura de; Nogueira, Marcelo; http://lattes.cnpq.br/2791448000405507; http://lattes.cnpq.br/1146968481041111Traditional boats are directly linked to the history of Brazil and its riverside communities. The traditional shipbuilding industry is one of the most important commercial activities in the world. The wood has excellent physical and mechanical properties and because it is a renewable material stands out among the materials that can be used in shipbuilding, taking into account the scarcity of non-renewable mineral resources. Based on this premise, this study aims to identify the wood and describe the construction method and the identification of the wood used in the fabrication of structural parts of traditional fishing vessels in the southern coast of Pernambuco. For the development of the activity will be interviewed naval carpenters, focused on the techniques of construction of wood pieces, which make up the structural and aesthetic set of the vessels, and the identification of the most used species. The analysis will be conducted considering that, in the traditional form of vessel construction, maintenance is performed every six months, due to the intrinsic characteristics of the wood, changes in the composition of the structure of the piece such as presence of xylophagous agents (fungi, termites and drills), drying defects (cracking, crushing, presence of knots). The project seeks to qualify naval heritage, a threatened segment of Brazilian heritage due to the significant loss of traditional vessels, human knowledge associated with them, knowledge about raw materials extracted from forests and their production techniques, to the detriment of new technologies and materials for naval production and also the social and environmental degradation of the traditional riverside communities of the southern Pernambuco coast. Currently using only four species: Pequiá (Caryocar villosum), Louro vermelho (Nectandra rubra), Sucupira Preta (Bowdichia virgilioides), Jaqueira (Artocarpus heterophyllus).Item Potencial energético dos resíduos gerados em madeireiras na Região Metropolitana do Recife - PE(2018) Damacena, Rafael Santos; Nogueira, Marcelo; Silva, Thiago Cardoso; http://lattes.cnpq.br/8962087913561252; http://lattes.cnpq.br/2791448000405507; http://lattes.cnpq.br/0769907892300910The exponential growth of the population brings with it several problems. Among them, a greater demand in the generation of energy of polluting sources and greater amount of residues generated. The objective of this work was to evaluate the energy potential of residues generated in two logging. Samples were collected at two logging sites located in the Metropolitan Region of Recife, in Pernambuco. The first sample obtained consisted of the mixture of dust residues of the species Maçaranduba (Manilkara sp.) And Jatobá (Hymenaea sp.). The second sample was a mixture of residues from two species, Maçaranduba and another unidentified The analyzes were carried out at the Forest Technology Laboratory, Department of Forestry Science, Federal Rural University of Pernambuco. The carbonisations were carried out in a digital muffle with temperature control of the brand MAGNU'S model 0910. The carbonization was performed at a rate of 1.4°C/min. Four carbonizations were performed, two for each sample. For the immediate analysis of the charcoal, the adaptation of the CETEC (1982) to ASTM (American Society for Testing and Materials) standards was used, thus it was possible to determine the contents of volatile material, ashes and by fixed carbon difference, dry basis. Charcoal produced by the mixed waste from two logging had an acceptable ash and ash content. The content of volatile materials is higher than desired and as a consequence has a lower fixed carbon content. The higher calorific value is above the average found in the study of Manilkara sp., Probably because the source material is not only maçaranduba. There was no significant difference between the results obtained by the samples, except for the moisture content.Item Evolução da produção florestal madeireira no Nordeste brasileiro frente ao setor nacional de 2006 a 2016(2018) Rocha, Kleydson Diego da; Braz, Rafael Leite; http://lattes.cnpq.br/7332493832361305; http://lattes.cnpq.br/1327427785910347The approval of a fiscal incentives act for reforestation in 1966, which allowed forestry companies to reduce up to 50% of their taxes to invest in forest projects, made the Brazilian forestry sector to start developing and gaining prominence. With results superior to those presented by industries in general and the agriculture sector in the participation in the Gross Domestic Product (GDP), the forest sector can be considered as a very promising and important sector for the national economy. However, the specific contribution of the Northeast region is very small, even worse, the discussions about the issue and how to boost the sector in this region are scarce. Therefore, the objective of this work was to analyze the evolution of the northeastern forest sector in the period between 2006 and 2016, in comparison with the national forest sector, with the intention of identifying weaknesses and opportunities and proposing alternatives for the development of this sector in the aforementioned region, with emphasis on the state of Pernambuco. For that, secondary data obtained from the online portal of the Brazilian Institute of Geography and Statistics (IBGE) were used. The results showed that in Brazil forest production is strongly influenced by the economy, inspections, bans on the exploitation of native forests and availability of labor, while in the northeast the influences are more associated with economic, legal and bureaucratic issues. Among the forest products studied, wood was the one that presented the highest contributions of Pernambuco to Northeast (11.47%), followed by charcoal (0.65%) and log wood (0.10%) in the last year evaluated. It was concluded that the main forms of incentive to the forest sector in Pernambuco and the Northeast should be related to legal issues in the formalization of the sector, fortification of existing market and incentives both fiscal and industrial development.Item Características físicas, químicas e energéticas de Poecilanthe grandiflora Benth.(2019) Figueiredo, Irismar Farias de; Baracho Junior, Expedito; http://lattes.cnpq.br/5574030858936157The objective of this work was to determine some physical and chemical properties of the wood of PoecilanthegrandifloraBenth, from Salgadinho municipality, João Bento Site of Batalha - Paraíba. The tests were carried out at the Forest Technology Laboratory of the Federal Rural University of Pernambuco - UFRPE, and at the Forest Products Laboratory of the Ministry of the Environment - MMA, in order to evaluate the results obtained. Disks were sectioned along the trunk to make the chips, presenting dimensions 50 x 20 x 2.5 mm. The carbonization process was carried out in a furnace adapted of the digital muffle type, in the total time of 3 hours and 30 minutes, reaching a maximum temperature of 450 ° C, having a heating rate of 1.4 ° C per minute. The standard used for immediate analysis was NBR 8112. For the wood of PoecilanthegrandifloraBenth, the ash and volatile materials, corresponding to 2.10% and 46.20%, respectively, were found through the immediate analysis of Coal. For the physical properties, 12.80% of moisture and 0.80 g / cm³ of basic density were obtained. In the Laboratory of the Ministry of the Environment, Ash and Extractive Content were found 1.79% and 14.94%, respectively. For basic and apparent density, 0.84 g / cm³ and 0.99 g / cm³ were obtained. It can be concluded that the wood presented good yield for energy generation, but also presented good technological characteristics, being classified as high density wood (class).Item Características físicas, químicas e energéticas de Poecilanthe grandiflora Benth.(2019) Figueiredo, Irismar Farias de; Baracho Junior, ExpeditoThe objective of this work was to determine some physical and chemical properties of the wood of Poecilanthegrandi flora Benth, from Salgadinho municipality, João Bento Site of Batalha - Paraíba.
