Os animais não humanos no material didático do programa São Paulo Faz Escola

The relationship between humans and non-human animals dates back to the Prehistoric Era, when groups of humans migrated from the nomadic and extractive stage to sedentariness, starting to develop agriculture and animal husbandry. Ancient Greek philosophy, notably the Aristotelian school of philosophy, posited that nature has not done anything for nothing, and all things have a purpose: plants were created for the sake of animals, and these for the good of men, while the Bible preaches the view that the world was created for the good of men and other species were subordinated to their wants and needs. During the Renaissance, centuries XIV to XVI, anthropocentrism was established as the main philosophical concept. However, in relation to the treatment of animals, Renaissance did not differ substantially from medieval scholasticism, considering animals like machines, devoid of pain and immortal soul. In this context, scientific knowledge about plants, non-human animals and nature in general, is built on anthropocentric values, thus influencing the construction of school education in the disciplines of Science and Biology. Nowadays, at São Paulo state schools, specifically in the Ensino Fundamental II (6th to 9th grade), the program of the discipline Ciências da Natureza e suas Tecnologias is set by the Currículo Oficial do Estado de São Paulo, via the São Paulo Faz Escola Program, implemented by the Secretaria Estadual de Educação in 2010. This documentary research used the methodology of Content Analysis and aimed to analyze the presentation of non-human animals in Caderno do Professor and Caderno do Aluno, from 6th to 9th grades of the discipline Ciências da Natureza e suas Tecnologias. The analysis of the courseware revealed that its contents were influenced by the anthropocentric view, in both implicitly and explicitly ways, conveying anthropomorphic, utilitarian, stereotyped and derogatory statements towards...

Sistema autônomo de iluminação utilizando energia solar

This work presents a self-sustainable lighting system using ultracapacitor as a storage device, replacing the conventional battery, using solar energy as the only energy supplier. A detailed study of solar panels, switched mode converters and ultracapacitors was made, in order to design a circuit capable of capturing solar energy and transfer it efficiently to a bank of ultracapacitors. Later, at nighttime, this energy is used for lighting in LED luminaires which have high luminous efficiency and high reliability index. This work presents the design of the solar panel, ultracapacitors bank, the development of the voltage converter circuit and charger working at the maximum power point of the solar panel. All subsystems were simulated and it was shown that the use of ultracapacitors is feasible to feed a LED lamp with enough brightness for a person to walk at night, for two night shifts, using a capacitive bank with twenty-four ultracapacitors. Replacing the battery by an ultracapacitor allows a faster recharge, with low maintenance costs, since ultracapacitors have a lifetime bigger than batteries; beyond reducing the environmental impact, as they don't use potentially toxic chemical compounds
