The control of Aedes aegypti encounters numerous difficulties and the most relevant point is the resistance that the mosquito has been presenting to the insecticides used in its control. Among the products alternative to synthetic insecticides, essential oils can be highlighted. Therefore, this work aims to evaluate the action of the chemical composition and larvicidal activity against Aedes aegypti of the essential oil extracted from the bark of the stem of the species Anibaduckei Kostermans. The essential oil was extracted by the hydrodistillation technique in a Clevenger apparatus.

Introduction: Patient safety is an important aspect of health care quality, since there is a need to develop strategies to improve service quality and minimize the occurrence of errors with the implementation of hospital accreditation programs. Objective: To analyze the contributions of hospital accreditation for patient safety of patient care in the hospital environment. Methodology: This is an integrative review of scientific studies published in SCIELO, MEDLINE, LILACS and BDENF between the years 2015 and 2020. Eleven studies were selected to compose the discussion of this study.

Monitoring the temperature of a power transformer has a crucial role to keep it's good performance, prolonging its lifetime, as well as, ensuring stability of the whole electric system. In this paper, we've estimated the top-oil temperature and the coil hotspot. A fuzzy logic-based methodology was developed leading to satisfying results compared to the IEEE-C5791 model.

Ensuring that assets in an electrical substation are managed only when needed is essential to minimizing maintenance costs. In this work, we present a system based on Artificial Intelligence (AI) to contribute to decision making about the performance of predictive maintenance. This system will provide substation operators with additional indicators of the operational condition of the transformers, determining which equipment is most likely to fail in the short term, based on analog and digital data from the substation supervision system.

A sociedade em caráter mundial está vivenciando um período de pandemia do coronavírus que se manifestou primariamente em Wuhan, na China, e que se alastrou de forma grotesca para todo o mundo. O novo coronavírus é responsável pela síndrome respiratória aguda grave denominada como Sars-CoV-2. Consequentemente os profissionais de enfermagem durante atuação profissional foram desafiados para prestar atendimento o enfrentamento do novo COVID19, por ser um vírus desconhecido, e a situação torna-se mais complexa, quando o indivíduo diagnosticado trata-se de gestante.

The occupation process of The Chapada Diamantina - located in the central part of the state of Bahia, Brazil - is directly associated with its peculiar Geodiversity, where geological and geomorphological aspects stands out. The region's growth was associated with two economic cycles: firstly, mineral exploration, which promoted the emergence of important cities and towns; and then what tries to explore the tourist possibilities of the Plate. It is worth noting that this second cycle is based on the roughness left by the first cycle, as well as on the scenic beauty, wells and waterfalls.

The Brazilian agricultural production exceeds the storage capacity, with that the construction of silo becomes essential, being the loads exerted by the product stored in the structure, the main factor for disasters in silos. In view of this, the present work aims to determine the pressures exerted by bean cultivars, according to EUROCODE 1.

Face shield is an equipment required for healthcare professionals to decrease the risk of contamination during the COVID-19 pandemic. Fused deposition modeling (FDM) is the most applied process of additive manufacturing due to its usability and low-cost, the injection molding (IM) is the fastest process for mass industrial production. In this study a qualitative comparison of these processes was performed for mass-production and distribution of face shields.

Introdução:A Avaliação Pré Anestésica (APA) é crucial para que o anestesista possa se planejar para uma intubação sabidamente difícil, que pode cancelar o procedimento, causar danos a via aérea ou mesmo, consequências irreversíveis, como hipóxia, parada cardiorrespiratória e sequelas neurológicas.

Objetivo: Relatar experiência vivenciada por cuidadora familiar no tratamento domiciliar à idosa acometida pela COVID-19. Método: Relato de experiência vivenciado por cuidadora de idosa que positivou para a COVID-19 em março de 2021, na cidade de Salvador, Bahia, Brasil. Foram adotados todos os cuidados para tratamento da idosa em domicílio, assegurando a implementação dos recursos prescritos pela equipe de saúde. Resultados: Transcorrido o período do isolamento, a idosa evoluiu com melhora clínica e pode retomar sua rotina habitual.
