Distribuição racional de água e energia elétrica entre os setores econômicos do estado do Ceará - uma análise insumo-produto

The deep economic modifications suffered by the State of Ceará, in the last two decades, have been increasing the consumption of production factors, among them, water and energy, essential to most productive activities. However, as the supply of both inputs, in the region, is limited, a shortage of these inputs can cause a disarticulation of the economy, with consequences to the productive structure, and to the level of employment. As so, to set priorities of use of these inputs, among the different economic sectors, are essential to assure the continuity of the State development. The main objective of this paper is to identify the main demanding sectors of water and electric power of Ceará and to estimate the impact in the consumption of these resources due to variations in the final demand of the macro-sectors of agriculture, industry, civil construction and services. For such, an ecological input-output model was developed for Ceará. The results show the sectors which are the more demanding on the consumption of water and electric power due to variations in the final demand, as well as those sectors more vulnerable to a possible rationings of these resources. The results allow one to conclude that policies that generate employment, income, or government revenue through taxation, should necessarily be associated with water and energy use, such that the continuity of the State economic development could be guaranteed

Chemical composition, antibacterial and antioxidant activities of the essential oil from Vismia guianensis fruits

In recent decades, the essential oils of plants have drawn great interest as sources of natural products. Essential oil from the fruits of Vismia guianensis was tested for its chemical constituents and antimicrobial and antioxidant activities. Gas chromatography/mass spectrometry (GC-MS) analysis of the essential oil revealed the presence of 38 sesquiterpenoids. The major components were β-caryophyllene (25.8%), α-copaene (13.1%), and δ-cadinene (11.6%). Antimicrobial activities were measured against six species of Gram negative and seven species of Gram positive bacteria and showed antibacterial activity against the human pathogenic Gram-positive bacteria Staphylococcus lentus with minimum inhibitory concentration (MIC) values of 78 μg/ml. The antioxidant activity of the essential oil was evaluated using the beta carotene/linoleic acid assay and showed antioxidant activity.Key words: Vismia guianensis, chemical composition, antibacterial, antioxidant, fruits, essential oil

Redesign e LIBRAS pela Educação e Acessibilidade Digital de Alunos Surdos

This article aims to present the redesign process of the digital educational material ”Primeiro, Aprender! Digital”, adapted for students who carry hearing impairment, by showing the strategies used in order to make modifications in its interface, so that it meets the specific needs of this public. A pilot version of the material was created and named “Primeiro, Aprender! Digital com Libras”, which is in tests phase, to verify wheter the adjustments contributed to the access of deaf people and, in future, the production of a series of classes based in the original product can be conducted

Academics' pesrpectives on Physical Education within the scope of inclusive education

Este artículo analiza las perspectivas de los académicos de la Educación Física en el contexto de la enseñanza y de la actuación con los estudiantes con discapacidad en la Educación Física y el Deporte en la escuela. El estudio tiene como objetivo analizar las opiniones de los académicos respecto al contexto de actuación. Esta investigación es de naturaleza descriptiva y transversal abordándose de manera cuantitativa. Se llevó a cabo por medio de una encuesta en la que 82 estudiantes de Educación Física respondieron a un cuestionario. Se realizó distribución de frecuencias, análisis factorial y análisis temático. Los participantes fueron de la opinión de que los objetivos de la Educación Física y el Deporte en la escuela, promover conductas sanas, la práctica del deporte y las relaciones socio-afectivas, son beneficiosas para el desarrollo del trabajo con personas con diferentes discapacidades. Creemos que este trabajo puede ser de ayuda en los planes de estudio de Educación Física y ayudar a gestionar y dirigir mejor la formación de profesores para los alumnos con discapacidades.This article discusses the perspectives of academics on Physical Education within the context of teaching and against the background of working with students with disabilities in Physical Education and Sports in school. The study is descriptive, cross-sectional in nature and seeks to analyze the academics’ opinions regarding Physical Education and Sports in school for students with disabilities. The research, which adopted a quantitative approach, was carried out by way of a survey in which 82 undergraduate students of Physical Education responded to a questionnaire. Distribution of frequencies, factor analysis and thematic analysis were conducted. Participants were of the opinion that the objectives of Physical Education and Sports in school promote healthy behaviour, the playing of sport and socio-affective relationships, as well as they are beneficial to an environment of working with different persons with disabilities. We believe this work may help in the curricula of physical education to better manage and direct the training of academics for students with disabilities.Este artigo discute a perspectiva dos acadêmicos de Educação Física sobre o contexto de ensino e o interesse em atuar com alunos com deficiência em Educação Física e Esportes na escola. O estudo tem por objetivo analisar as opiniões dos acadêmicos sobre o contexto atuação Educação Física e Esportes na escola para alunos com deficiência. O estudo é de natureza descritiva e transversal e que utilizou abordagem quantitativa via pesquisa por levantamento em que 82 alunos de graduação em Educação Física responderam a um questionário. Foi realizada distribuição de frequências, análise fatorial e análise temática. Na opinião dos acadêmicos, os objetivos da Educação Física e Esportes na escola são estimular a adesão de hábitos saudáveis, prática esportiva e relações sócio-afetivas, bem como apresentam interesse em atuar com diferentes públicos com algum tipo de deficiência. Acreditamos esse trabalho pode ajudar nos currículos dos cursos de Educação Física a melhor direcionar a formação dos acadêmicos para o público dos alunos com deficiência.peerReviewe

O presente trabalho discute e apresenta os resultados de um experimento realizado na disciplina de algoritmos e programação de computadores de uma escola pública, utilizando o método de ensino Peer Instruction (Instrução por Pares). O objetivo foi avaliar a eficácia do método, considerando aspectos referentes ao desempenho e o engajamento de estudantes novatos e experientes em programação do curso Técnico em Informática integrado ao Ensino Médio. Análises preliminares mostram um crescimento no desempenho dos alunos e indicam que aqueles em iniciação na programação têm uma pré-disposição em trabalhar de modo colaborativo comparado aos alunos com mais experiência

Chemical composition, circadian rhythm and antibacterial activity of essential oils of piper divaricatum: a new source of safrole

The essential oils from leaves, stems and fruits of Piper divaricatum were analyzed by GC-MS. The tissues showed high safrole content: leaves (98%), fruits (87%) and stems (83%), with yields of 2.0, 4.8 and 1.7%, respectively. This is a new alternative source of safrole, a compound widely used as a flavoring agent and insecticide. The leaf's oil showed antibacterial activity against gram-negative bacteria while safrole was active against Salmonella Typhimurium and Pseudomonas aeruginosa. In addition, the study of circadian rhythm of the safrole concentration in the essential oils of leaves showed a negligible variation of 92 to 98%
