Analysis of the planning of the flow of military inputs and supplies by the amazonian river modal

Logistics is understood in the art of engineering, planning, storing, moving, distributing and transporting in different axes, either internally or externally to organizations in the calculated time and in the correct place in a logical way, as well as the meaning of this word in its Greek origin.

Hpv vaccine to prevent cancer of the cervix of uterus

Objectives: search in the literature publications of the last ten years aiming to discuss the importance of the HPV vaccine for the prevention of cervical cancer. Methods: integrative review, with searches in the databases of LILACS, BVS, Scielo, Bireme. Results: We selected 81 publications, where 08 were read and adapted to the inclusion criteria. The diversity of studies emphasize the importance of the HPV vaccine in the age group from 9 to 13 years.

Reducing the environmental impact with emphasis on the use of pcr resin in the manufacture of preforms for pet packaging

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.

Energy production through the contact of piezoelectric crystals, in a teaching institution in the City of Manaus- Amazonas

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.

The investigation of the fluvial erosion of the rio guamá, belém (pa), aiming at the detection of degraded areas in critical stage, using the spontaneous potential method

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.

Study of mechanical and durability properties of mortars using slate waste

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.

Bioprospection of mangaba (Hancornia Speciosa Gomes) native in the transition region savanna-restinga

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.

Crédito de carbono gerado em terras indígenas: uma análise a partir do modelo pressão-estado-impacto-resposta (peir) de sustentabilidade ambiental

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.

Optimizing road safety in the city of bertoua, using the electre iii method

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.
