O comércio ambulante de alimentos é uma das atividades que mais cresce no mundo, sendo alternativa econômica aos estão fora do mercado trabalho. A preocupação com a qualidade sanitária se destaca, principalmente devido riscos contaminação provenientes ambiente manipulação. Foram avaliadas as condições higiênico-sanitárias na cidade São Luís- MA, para isso, foram selecionados quarenta e nove locais comercialização maior fluxo pessoas. Tratou-se pesquisa quantitativa, coleta dados feita usando...
A sepse, que se caracteriza como disfunção de múltiplos órgãos e/ou sistemas por uma resposta inflamatória desregulada do hospedeiro à um quadro infeccioso, pode levar encefalopatia associada sepse (SAE), síndrome multifatorial leva cerebral com dano irreversível. Este é comum e ainda mal compreendido em pacientes internados na UTI, levando a déficits cognitivos graves até ao óbito. Neste sentido, o propósito deste artigo revisar as principais características, fisiopatologia, diagnóstico,...
Compostos derivados de produtos naturais surgem como uma alternativa terapêutica para o tratamento câncer. Nessa perspectiva, essa revisão integrativa da literatura com análise bibliométrica tem objetivo investigar os principais componentes bioativos própolis que apresentam atividade anticâncer em células câncer oral. As buscas eletrônicas foram realizadas nas fontes informação MEDLINE via PubMed, LILACS e SciELO. Após aplicação dos critérios elegibilidade, quatorze artigos incluídos nesta...

A adaptação da interface implante/pilar é essencial para o sucesso de próteses dentárias, pois microfendas podem favorecer a infiltração bacteriana, comprometendo durabilidade do sistema. O objetivo avaliar e selamento microbiológico na com pilares retos angulados (30º), sem ciclagem mecânica. Foram analisados 40 implantes cone morse divididos em 4 grupos, considerando angulação (reto ou angulado) mecânica (500.000 ciclos, 120 N, 2 Hz). As interfaces foram avaliadas por microscopia...
The composite materials are well known by their excellent combination of high structural stiffness and low weight. Their inherent anisotropy allows the designer to tailor material in order achieve desired performance requirements. Thus, it is fundamental importance develop tools that allow obtain optimized designs considering requirements, functional characteristics restrictions imposed production process. Within these this work considers dynamic behavior components manufactured from fiber...
Purpose The additive manufacturing technologies have been facing an extraordinary growth along the past years. This phenomenon might be correlated with rise of low-cost FDM into non-professional market segment. In contrast that, among main disadvantages found in this sort equipment are final object finishing and low mechanical strength. For that reason, purpose paper is to present characterise a surface treatment which based on solvent vapour attack also known as smoothing process. addition,...
In recent years, additive manufacturing technologies have been playing an important role in the global economy. Consequently, low-cost 3D printers rose domestic environment, accelerating development of startup companies and new market segments. Nevertheless, with regard to printing based on fused filament fabrication, several challenges still need be overcome, such as those related surface finishing mechanical strength. Moreover, environment also generates untreated plastic waste, which can...

This work proposes a procedure to estimate the dynamic damped behavior of fiber reinforced composite beams in flexural vibrations. A set experimental tests were carried out order investigate natural frequencies and modal shapes. These results are used evaluate damping factors by program FREQ. then as input analysis Finite Element Method, using Rayleigh Model. good agreement between theoretical was obtained. Thus, it became possible validate proposed beams.
