This article aims to get to know the profile of bedridden users and describe how access to rehabilitation services ocurr. This is a population-based cross-sectional study in which bedridden users residing in urban regions with coverage of the family health strategy in the northern health district of Campo Grande / Mato Grosso do Sul were invited to participate. Home interviews were conducted where data on clinical profile, sociodemographic data and on access to rehabilitation services were collected.

The objective of this work was to approach a freehand restorative technique for class IV in composite resin. The procedure was performed on a mannequin containing elements 12, 11,21 and 22, the technique was performed on element 21, the same was provided with the ready preparation, vestibular bevel, the resins of choice were DA3, BA3, EA2 e CT all from Z350 - 3M, as each contains different chromas. Today for restorations on teeth older than 3M it is the good option on the market, with the patent for nanoparticulate resins.

Objetivo: Analisar as produções científicas a respeito de tecnologias em enfermagem que envolve cuidados ao recém-nascido prematuro internado em uti neonatal e o método canguru disponíveis nas Revistas LatinoAmericana, Revista Brasileira de Enfermagem (REBEN) e Revista Texto e Contexto Enfermagem. Método: Trata-se de uma revisão integrativa da literatura com abordagem qualitativa, que buscou identificar produções sobre o tema tecnologias em enfermagem ao recém-nascido prematurointernados em uti neonatal e sobre o método canguru, entre 1997 a 2018.

The low-temperature water-gas shift reaction (WGSR) is already used in several industrial chemical processes. However, interest in this reaction has increased significantly in the last few years because of the advances in fuel cell technology and the need to develop compact reformers for the production of pure hydrogen streams (free from CO). In the present work, the WGSR was carried out on copper-based supported catalysts, one of them already used in the industry and the other one prepared using the sol-gel method with the same composition as the industrial catalyst.

The teaching methods used by teachers determine the extent to which students perform in their academics. This study examines the relationship between teaching methods and academic performance of secondary school students in Nigeria. The study adopted descriptive research design but with mixed approaches of data collection and analysis. Target population comprised of 180 students in three secondary schools in Nassarawa Local Government, Kano. A total of 60 respondents were selected. The research instrument was a questionnaire.

To Este estudo tem por objetivo analisar a mortalidade evitável como indicador de disparidades na mortalidade por raça/cor e sexo em uma Região de Saúde do Maranhão. Configura-se como trabalho do tipo ecológico realizado emsete municípios da Região de Saúde de Caxias com base nas declarações de óbitos ocorridos entre 2006 e 2015. O método de análise estatística foi baseado na regressão binomial negativa.No período estudado, ocorreram 5.277 óbitos por causas evitáveis.

This study was carried out to identify the cognitive and affective strategies for improving the teaching and learning of modern physics in Ebonyi State Colleges of Education, Ikwo in southeast Nigeria. Two research questions were developed in line with the purpose of the study. Two null hypotheses were formulated and tested at 0.05 level of significance. The study adopted descriptive survey design. The population of the study is 76 male and 57 female students of departments of physics and integrated science who offer courses in modern physics from the area of study.

Este artigo objetiva apresentar o conhecimento existente sobre a arqueologia dos registros rupestres da bacia do Itapecuru - Maranhão, precisamente nos municípios que se situam nas porções do Alto e Médio curso deste rio, com base na sistematização da bibliografia e organização de dados inéditos, com vistas a identificar a distribuição espacial das ocorrências e fornecer uma caracterização da região para pesquisas arqueológicas mais intensivas.

This work aimed to study the influence of mica (muscovite type) particle size in recycled highdensity polyethylene (rHDPE) matrix on wetting behavior and morphological, physical, and chemical properties. The r-HDPE/mica composites were compounded with a fixed ratio of 85/15 (weight percentage), varying the mica particle size (45, 75, 100 and 125 mm). The rHDPE and composites were fed into a twin-screw extruder.

Today there are few educational institutions that carry out activities that promote entertainment, fun and the inclusion of visually impaired people in the educational environment. In this article it is presented a playful form of teaching in which there will be a greater social inclusion for the visually impaired in an institutional environment.
