The production of Polyethylene Terephthalate - PET has been one of the elements that cause concern in the modern industry to the environment, due to the disposal of the product discarded after use. This work shows the use of post-consumer resin (PCR) as one of the means to reduce the environmental impact generated by PET production.
Electric energy is responsible for several factors that keep us active and in communication with the rest of the world, where they present various ways of producing electric energy, including renewable energies. The most used type of energy is linked to non-renewable sources, causing numerous environmental impacts, other types can be described for power generation considering less consumption, greater stability, lower cost as in the case of piezoelectricity, which is still little used.
This work presents a geophysical study of part of the riverbank subject to erosion, with the primary objective of evaluating its use in the detection of areas degraded by erosion in a critical stage, before its collapse. This area is located along 600 m along the Guamá River, between the Tucunduba River Bridge and the Canoeing Port, within the campus of the Federal University of Pará (UFPA), in the city of Belém in the State of Pará (Brazil). It has, in some sections, different types of erosion containment, including concrete wall and cement bags.
This study was focused on the addition of slate waste to Portland cement to evaluate the potential utilization as a mineral addition. The physical characterization of the residues was done by granulometric analysis and X-ray diffraction. The pozzolanic activity was evaluated by electrical conductivity, modified Chapelle, Luxan method and thermogravimetric analysis.
This research aimed to determine the chemical and antioxidant properties of mangaba fruits from the Savanna-Restinga region in the State of Maranhão. Ripe fruits from mangabeira matrices originating from naturally occurring areas were analyzed. Morphometric analyzes of length and diameter were performed on the fruits. In the chemical characterization, the contents of lipids, mineral residue, fibers, proteins, vitamin C, carbohydrates, starch, ºBrix, pH, ATT and minerals were investigated according to recommended methodologies.
Este estudo tem como objetivo verificar, pelo Modelo Pressão-Estado-Impacto-Resposta (PEIR) de indicadores ambientais, se o Projeto de Carbono Florestal Suruí (PCFS) gerou benefício proporcionando sustentabilidade ambiental para a comunidade indígena. A expectativa é que diante da geração de benefícios e sustentabilidade esse tipo de projeto possa ser implementado em outras comunidades indígenas.
The overall objectif of this study to optimize road safety in the development of urban roads in the city of Bertoua. To that end, we analyzed data collected by the GPS system, exploited satellite images of the Bertoua urban road network as well as the statistics on road accidents recorded in that city. The aim of these analyses was to take stock of road safety in the city.
This paper intends to present to the portuguese community a translation of a remarkable paper of Paul Feyerabend on art-science.
The work presents a study that aims to analyze certain products in a company in the commercial branch of dairy products of animal origin. Analyzes will be carried out on the sliced cheese products, the butter jar and the chocolate drink, as they present more critical problems in relation to the recipe. Through the analysis of these products, there will be a demonstration of results in the verification of their quality. To make a study with better sales rates, we will use some tools used in the classroom.
The perspective of an understanding of this incongruity between the understanding of the relevance and the disuse of PPE in the hospital unit is the objective of this study. This is a descriptive, exploratory, qualitative study carried out in two hospital units in the Cariri region of the State of Ceará with 76 health professionals, in the category of nurses and nursing technicians. It is noticed that most participants consider it relevant and essential for health prevention and promotion, in addition to minimizing or avoiding contamination by exposure during the practice of care.
