Due to a need to search for a new form and improvement in electric power quality, we can cite the best performance of capacitive filter installations, in order to remove from the electrical system the harmonics, transients, distortions among others, thus avoiding the burning of equipment, machines, lamps. This system in addition to protect system, provide energy saving due to the RLC system, in parallel acting together, removing all evils from the power grid and diverting to ground. The results show the efficiency of the application for the good economic performance of the companies.

Cette recherche visait à étudier l'intégration du genre en milieu rural à travers la participation des femmes au développement socio-économique dans le territoire de Walikale à l’Est de la République Démocratique du Congo. Une approche méthodologique qualitative a été adoptée pour mener les enquêtes sur le terrain en utilisant les techniques d'entretien semi-directif et d'observation directe. Un échantillon typique ou « par choix raisonné » a été tiré parmi les femmes ménagères, entrepreneuses et salariées. Au terme du processus d'échantillonnage, 56 individus ont participé à l'enquête.

The progressive use of power electronic devices, connected to the electrical system, has contributed to the increase of problems caused by harmonic disturbances in electrical networks. Thus, this work aims to develop a methodology to analyze the harmonic impacts on the electrical grids caused by non-linear loads with the use of the Decision Tree technique.

A Odontologia legal participa dos processos de identificação post-mortem de diversas formas como: estimativa de sexo e idade, ou até nas determinações de grupos étnicos. O seio frontal é caracterizado por ser único e individual, sua forma permanece praticamente inalterada durante toda a vida adulta do indivíduo. Assim, é aplicável a identificação humana, com auxílio da tomografia computadorizada de feixe cônico e radiografias extrabucais.

Objetivo: Avaliar se a associação da deficiência de vitamina D com o excesso de gordura visceral potencializa o risco de calcificação coronariana em pacientes assintomáticos.Métodos: Trata-se de um estudo transversal, envolvendo pacientes atendidos ambulatorialmente em hospital referência em cardiologia. A calcificação foi avaliada pela tomografia computadorizada(TC) e o escore total da calcificação coronária(ECC) correspondeu à soma do escore de todas as artérias coronárias, sendo considerado como ausente ECC=0 e presente ECC>0.

This work presents a new approach for the treatment of surplus reactive energy in industrial plants that has capacitor banks in the substation in obsolescence and limited to high numbers of maneuvers. The purpose of this thesis is to perform studies for the purpose of optimizing a discrete distributed system, from data sampled in the industrial sector, which contains problems in the substation power factor control system and consequently reactive energy surplus.

Objetivo: Analisar a injuria renal (IRA) aguda nos pacientes com COVID-19, assim como os fatores que propiciam seu desenvolvimento, além de descrever os mecanismos da infecção renal por SARS-COV-2 e checar a utilização da terapia renal substitutiva (TRS). Método: Revisão sistemática baseada no PRISMA-p. A busca foi realizada em base de dados indexadas a partir de estratégias especificas para cada base, descritores utilizados: Acute Kidney Injury; Renal Replacement Terapy; COVID-19, com artigos publicados entre 2020 e Agosto de 2021.

This study aims to analyze the effect of psychodrama therapy on social anxiety among university students. The methodology adopted in this quasi-experimental pre and post-test research, the specialized random sample collection method has been used and the subjects of the study were university students. A total of 30 students were selected and divided into two groups experimental and control. The experimental group received twelve 90mins of psychodrama sessions. The control group didn't receive any treatment. Finally, a post-exam was conducted for both groups.

The study of analysis and description of human gait encompasses clinical and biomechanical data regarding the locomotor system, motor control and movement mechanisms. Gait initiation surveys provide information on gait recognition, diagnosis, follow-up and, when necessary, establishment of appropriate physical therapy and/or surgical treatment. The present study aims to identify the biomechanical methods and their respective techniques used to assess and understand the mechanisms of gait initiation in children.

Objective: To identify and analyze the scientific literature on the evidence on protective factors for obesity in adolescents. Method: Systematic literature review based on the PECO strategy and PRISMA. A search was carried out in the following databases: Virtual Library on Adolescent Health; Cumulative Index to Nursing and Allied Health Literature; Latin American and Caribbean Literature in Health Sciences; National Library of Medicine and National Institutes of Health; Scopus and Web of Science. Results: 3459 studies were identified, of which five were included.
