1. Power amplifier circuits for functional electrical stimulation systems
Abstract Introduction: Functional electrical stimulation (FES) is a technique that has been successfully employed in rehabilitation treatment to mitigate problems after spinal cord injury (SCI). One of the most relevant modules in a typical FES system is the power or output amplifier stage, which is responsible for the application of voltage or current puls

2. Towards a philosophy of energy
Transition to a sustainable energy regime is one of the key global societal challenges for the coming decades. Many technological innovations are in the pipeline, but an uncritical appraisal of anything and everything called green innovation lacks methods for testing both the necessity and the sufficiency of these developments. We propose to develop a philos

4. O livro digital no mundo editorial e a evolução histórica do copyright e das estratégias de apropriação de lucro / The digital book in the publishing industry and the historic evolution of copyright and the resulting strategies for profit appropriation
Por que a indústria editorial está empreendendo a difusão do livro digital quando esse padrão tecnológico perturba o regime de proteção e enforcement do copyright? Se a duplicação da criação intelectual e sua transmissão simultânea por meio de um arquivo digital inviabiliza o aparato coercitivo que ampara o enforcement do copyright, emerge daí

5. O uso da educação online como alternativa para os programas de pós-graduação stricto sensu no Brasil. / The use of the education online as alternative for the after-graduation programs stricto sensu in Brazil.
So that a nation can be considered as developed, one of the major targets of its government should be the constant investments in education over the time. In Brazil, a country with continental dimensions, the offer of education for everybody is not an easy task at all. The successive governments in this country have put into practice several measures in all

6. Sciences et État: note critique sur quelques propositions théoriques
The profusion of theories within science and technological studies sometimes makes it hard to find lines of direction or stable points of support. The question of the relations between scientific practices and the state affords an opportunity to appraise the differences between theoretical corpi. The present article explores three recent theoretical proposit

8. Exchange rate policies, patterns of specialization and economic development : theory and evidence in developing countries
The objectives of this paper are twofold. First, it intends to provide theoretical elements to analyze the relation between real exchange rates and economic development. Our main hypothesis is very much in line with the Dutch disease literature, and states that competitive currencies contribute to the existence and maintenance of the manufacturing sector in

9. Velhos conhecimentos, novos desenvolvimentos : transições no regime sociotécnico da agricultura : a produção de novidades entre agricultores produtores de plantas medicinais no sul do Brasil
A noção de que o desenvolvimento é um processo relacionado a um progresso técnico positivo e linear contribuiu para gerar um cenário social e ambiental insustentável e, aparentemente, tem conduzido a sociedade contemporânea para uma homogeneização cultural e material. Ao contrário, observando amiúde os espaços rurais, se identifica que há a emer

11. Andreev transport in double quantum dots coupled to superconductor and ferromagnetic leads / Transporte por reflexão de Andreev em pontos quanticos duplos acoplados a eletrodos supercondutores e ferromagneticos
In this work we studied the quantum transport in two hybrid nanostructures composed of double quantum dots (DQD)s coupled to superconductor (S) and ferromagnetic (F) leads. The first nanostructure, denoted by F - QDa - QDb - S, is composed of a ferromagnet, two quantum dots, and a superconductor connected in series. In the second nanostructure, denoted by (

12. Viabilidade técnica de uma rota não convencional para a produção de leite de cabra em pó em cooperativas do Rio Grande do Norte
Nowadays, Brazil has both the greatest goat herd and the greatest goat milk production of South America. The state of Rio Grande do Norte, located in northeast of Brazil, has an average year production of three thousand cubic meters of goat milk in natura. Part of this milk production is homemade and it comes from small farms, which unite in rural cooperativ
