ABSTRACT
ABSTRACT Sustainability and economics are current issues in the generation of electricity. The energy matrix is diversified and some forms have stood out, such as wind. Some tools have been developed to improve project efficiency, one of which is Life Cycle Assessment (LCA). This presents solidity when assisting projects financially and environmentally, evaluating materials and processes. The present study aimed to analyze the application of LCA in a wind power plant. After searching the main databases and using filters, the analysis was developed from the information of an article that described the application of the LCA to a wind power plant using computational simulation, providing an overview of the production and potential environmental impacts for the process manufacturing, parts maintenance, disposal and recycling at end of lifespan. The phases, steps and the threshold diagram of the LCA system were observed. The results showed a high rate of reuse/recycling of some materials and significant reductions in emissions, financial costs and abatement of environmental payback if the materials were recycled at the end of lifespan. Recycling has shown positive environmental aspects and a significant cost reduction, allowing the expansion of markets and optimization of wind projects.

A fibromialgia (FM) é uma doença idiopática de ordem reumatológica e incurável que causa dores crônicas e possui tratamento complexo e multifatorial. O exercício físico pode fazer parte do tratamento por atenuar parte dos sintomas da FM, porém a literatura ainda carece de informações sobre tipo, intensidade, duração e frequência ótimos contra os sintomas da FM. O objetivo do presente estudo foi verificar o efeito de 12 semanas de treinamento resistido em uma paciente com FM que não fazia tratamento farmacológico. Os resultados indicaram que 12 semanas de treinamento resistido foi capaz de reduzir as dores, melhorar a capacidade funcional, o bem-estar geral e a qualidade de vida da paciente. O treinamento resistido pareceu atenuar os efeitos negativos da FM e parece ser uma ferramenta promissora para pacientes com FM que gostem desse tipo de atividade.
Fibromyalgia (FM) is an idiopathic rheumatological order and incurable desease that causes chronic pain and has complex and multifactorial treatment. Exercise may be a part of treatment by relieving some of the symptoms of FM, but the literature still lacks optimal information about type, intensity, duration and frequency against the symptoms of FM. The aim of this study was to verify the effect of 12 weeks of resistance training in a patient with FM that had no pharmacological treatment. The results indicated that 12 weeks of resistance training was able to reduce pain, improve functional capacity, general well-being and quality of life of the patient. Resistance training appeared to attenuate the negative effects of FM and seems to be a promising tool for patients with FM who enjoy this kind of activity.

O medo de cair é um dos principais problemas em indivíduos pós acidente vascular encefálico (AVE). A imaginação pode ser uma experiência sucedida para diminuir este aspecto. O objetivo deste estudo foi verificar o efeito de um programa de imaginação de curto prazo no medo de quedas em indivíduos pós-AVE. Sete indivíduos acometidos por AVE participaram do estudo. A Escala Internacional de Eficácia de Quedas (FES-I-Brasil) foi aplicada antes (PRÉ), depois (PÓS) e sete dias após a intervenção (RET). Foram realizadas quatro sessões de familiarização e seis de prática da imaginação. Não houve diferença significativa no escore total da FES-I-Brasil após intervenção (p=0,46), exceto na tarefa subir/descer escadas (PRÉ e PÓS, p=0,04; PRÉ e RET; p=0,01). Apesar da melhoria na tarefa subir/descer escadas, alterações nos demais itens da escala não foram encontradas o que pode representar um efeito relativamente reduzido do programa de imaginação de curto prazo.
The fear of falling is one of the main problems with subjects after stroke. Imagery could be one succeed experience to decrease this issue. The aim of this study was to verify the effect of a short-time imagery intervention in fear of falling in subjects after stroke. Seven individuals affected by stroke participated in the study. The Falls Efficacy Scale International (FES-I-Brazil) were used before (PRE), after (POST) and seven days after intervention (RET). Four session of familiarization and six of imagery were performed. There were no difference in FES-I-Brazil score after intervention (p=0.46), except in up/down stairs task (PRE and POST, p=0.04; PRÉ and RET, p=0.01). Although, the improvement in up/down stairs task, no more changes were found in the scale items, which could represent a relatively reduced effect of short-time imagery intervention.
