    Dinâmica do risco de incêndios sob efeito do El Niño em paisagem do bioma Caatinga em Petrolina - PE
    (2023-02-17) Feitosa, Márcio Faustino; Silva, Emanuel Araújo; Souza, Ioneide Alves de; http://lattes.cnpq.br/0383867840261318; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/7669915736150355
    Remote sensing techniques have been used since the 1960s to work on a particular object or specific area. Over time, technologies have gained improvements and new software and high resolution satellites have emerged. The Landsat-8 satellite can capture scenes up to 705 km away from earth, with a percentage of 10% of clouds, these scenes can be processed and studied for a certain purpose, among these was the dynamics of fire risk under the effect of El Niño in landscape of the Caatinga Biome. Therefore, it is intended to study the vulnerability of Caatinga and the use of monitoring technologies. The objective of this work is to evaluate the influence of El Niño on the dynamics of fire risk under the landscape of the Caatinga biome in Petrolina-PE, monitoring the risk of fire in relation to the severity of El Niño. Images of the Lansat-8 satellite in the municipality of Petrolina-PE were obtained from the USGS website. The following criteria were adopted for image selection: Data from 2015 to 2020, counting from August 1st to December 31st, at times when there are few precipitations, few clouds and high temperatures due to the warmer months. The tool in data processing was Qgis software, a free license software, indicated for those seeking high quality in academic work in the area of Remote Sensing. In the interval of these years, six fire risk maps were obtained. Togenerate the forest fire risk maps and adopted the AHP methodology, widely used by several authors. Where we obtained eight variables: hypsometric map, land use and occupation, slope orientation, slope, road system, precipitation, surface temperature and vegetation index of the normalized difference. According to the results, a temporal analysis of fire risks was obtained, proving that the years 2015 to 2018 had a continuous increase, and in 2019 and 2020 there was a fall in fire risk. Between these last years there was an El Niño and a La Niña and 2020 was the year that the pandemic occurred, that is, there were few transport flows on the highways, causing low risk of fires.

    A utilização da ferramenta PDCA na gestão de uma empresa de tratamento e destinação de REEE – estudo de caso Recife

    The present work is related with electronics waste (EWA) treatment and disposal. The generation speed of this kind of waste, on a worldwide scale, is in the order of 20 to 25 million tons a year. This result is a concern of environmental preservation agencies. As these waste ware potentially contaminants, in large proportions, of biotic systems in soil, water and air. The case study uses the tool Plan-Do-Check-Act (PDCA), developed by Walter Andrew Shewart, having two distinct periods of foundation, 1931 and 1939, through his books: Economic Control of Quality of Manufactured Product, and Statistical Method from the Viewpoint of Quality Control. This tool was suggested for the referenced company in order to optimize the operationalization of treatment and disposal of the EWA. Thus enable the speed of transformation into economically and environmentally viable by-products. Although far below the generation speed of these kind of waste. In the specific case of Brazil there is the National Solid Waste Policy (NSWP) associated with the law 12.305/2010, in force. Arising from the decree 10.240/2020, the reverse logistics of electronics products becomes mandatory Nationwide with due legal protection, and with the use of the PDCA tool, implemented in the electronics waste treatment and disposal company, there is a perspective of continuous improvement. The result of optimized management and legal provisions generates the mitigation of large-scale environmental impacts. Noting that the physical and Chemical components of electronics are extremely harmful to all natural resources, therefore, it is necessary to pay careful attention to environmental public policies.

    Biossegurança nos laboratórios de pesquisa e práticas do Departamento de Ciência Florestal da Universidade Federal Rural de Pernambuco
    (2019-12-03) Lima, Carlos Roberto de; Berger, Rute; Galdino, Rosa Maria Nunes; http://lattes.cnpq.br/0318992418792614; http://lattes.cnpq.br/5395827385005105; http://lattes.cnpq.br/2847013832175027
    To prevent accidents and discarding of residues, as well as the use of suitable equipment to the laboratory, is the main challenge of biosecurity that should be induced on every beginner laboratory users, as well to the “experienced” ones at any activity setup, that utilize a place to prepare activities, which manipulates products or procedures that are dangerous to human, animal and environment health. Objectified analysis of three Research Laboratories utilized to practical classes, two being of computer science and the other the tree nursery from the department of forestry science of Universidade Federal Rural de Pernambuco – Campus Recife , on the criteria established on norms and work safety laws, Solid Residues and Effluents, as well to evaluate the risks of the activities and to generate a risk map. The methodology included the gathering of processes and activities executed at each laboratory, by each of its respective coordinators and researchers. There were observed problems on the infrastructure and the use of individual and collective safety equipment, the lack of adequate personal training, which requires attention and investments from the State about the biosecurity.
