Objetivo: Revisar sistematicamente publicações referentes a integralidade do cuidado na circulação extracorpórea. Material e Método: Revisão sistemática entre os anos de 2010 a 2021, que teve como critérios de inclusão: artigos no idioma português brasileiro, que estivessem dentro do período estabelecido e condizente com a proposta do objetivo. Excluíram-se da pesquisa: trabalhos não correspondentes ao objetivo, fora da linha temporal e em outros idiomas.

Jamanxim National Park is an integral protection area located in a region of use conflicts and high deforestation rates in the Brazilian Amazon region. This park was established, in conjunction with other protected areas also located in the region of influence of BR-163 highway, with the aim of stopping native forest deforestation close to the road.

A complexidade típica de um sistema federativo de organização estatal, aliada à existência de um grande número de tributos e das respectivas competências dos entes federados gera muita confusão na interpretação das leis tributárias brasileiras. No setor de distribuição de energia elétrica, tem ocorrido muita discussão sobre a base de cálculo dos tributos de competência federal PIS e Confins. O centro das discussões refere-se à dúvida sobre à consideração do valor do imposto de competência estadual ICMS na base de cálculo dos dois tributos federais supracitados.

Government policies for Building Information Modeling (BIM) dissemination are driving BIM implementation in markets around the world. This paper aims to map scientific knowledge produced about the subject. The mapping included analysis of 812 articles published between 2011 and 2021 and extracted from the Web of Science. Cite Space analysis software extracted indicators such as frequency of occurrence of words and cluster analysis. These indicators reveal the knowledge base, topics little explored by researchers, and the main research areas on BIM implementation.

Among the types of waste, there are the domestic solid wastes that consist of discarded materials from domestic activities in urban residences. In this connection, recycling is defined as recover materials that would be discarded using them to produce new products. The objective of this research was to prepare aninstructionmanual and a Standardized Operating Procedure (SOP) for product a handmade basket from recycled aseptic carton packaging for bicycles. Firstly, the basket’s material was collected and a prototype was produced.

Amostras de um aço inoxidável super duplex compostas por uma matriz ferrítica e partículas dispersas de austenita foram deformadas com ensaios de torção nas temperaturas de 900°C a 1200°C e taxas de deformação variando de 0,01 s-1 a 10 s-1. Os resultados desses experimentos são apresentados na forma de curvas de escoamento plástico com a temperatura e a taxa de deformação constantes. A forma das curvas depende da temperatura e da taxa de deformação e varia com a fração volumétrica de austenita; o fluxo plástico em aços bifásicos é mais complexo que em materiais monofásicos.

Using titanium as the base metal of biomaterials has gained attention due to its excellent mechanical properties, biocompatibility, and resistance to corrosion and wear. In this research, Ti6-Al7-Nb (wt%) alloy has been superficially modified by cationic cathode plasma nitration (CCN) in order to improve the pre-existing biocompatible characteristics in the alloy. Four treatment conditions and a standard sample, for comparative purposes, were chosen. Nitriding was implemented using a cathodic cage technique at a different time and temperature conditions, and at constant pressure.

In large number of engineering tasks, heat transfer takes place over time, i.e., physical bodies are in non-stationary (transient) conditions.We will use an implicit numerical method for calculating the temperatures at fixed time intervals for certain nodes of the studied body.

O objetivo dessa Temperature control in computers, mobile devices and other devices is important for their stability. The finite differences method is used to calculate the temperatures in fixed nodes of devices, in the absence of internal heat dissipation and certain boundary conditions of the inner walls.

Background: The femoral artery has been the standard access route for several decades. However, this access route has been associated with increased rates of vascular complications compared to the radial artery access route. The objectives of this study were to describe vascular complications at femoral access site after puncture without transfixation of the artery. Methods: This a was real-world registry (from January 2017 to August 2019) that enrolled 1000 patients (mean age 56±10years) with stable CAD and clinical indication of coronary angiography.
