Pensar o desafio Biotecnológico com Francis Fukuyama

Para tentar mostrar o interesse da proposta bioética de Francis Fukuyama centro-me, acima de tudo, na sua obra “O Nosso Futuro Pós-Humano”, por entender que o autor, nesta obra, faz uma defesa da ética nas ciências biológicas que é ponderada no sentido da sua viabilidade porquanto é realista: não pretende parar pura e simplesmente o progresso científico, como não concorda que se deva entregar à ciência a respon...

Development of IgY antibodies in chickens and IgG in rabbits immunized against ...

Pythiosis is caused by Pythium insidiosum and the occurrence of disease in horses was described in the North and Northwest State of Rio de Janeiro, Brazil. The disease was described in cattle, sheep, humans, and horses in different states and regions across the country. This paper describes the development of IgY and IgG polyclonal antibodies, in chicken and rabbits, respectively against proteins extracted from...

Dissertação de Mestrado em Comunicação Educacional Multimedia apresentada à Universidade Aberta ; De há uns anos a esta parte, tem vindo a disseminar-se entre os professores o acesso às novas tecnologias de informação e comunicação tendo como principal função a gestão dos processos de ensino e aprendizagem. Numerosos estudos têm sido desenvolvidos no âmbito das dinâmicas da sala de aula decorrentes da integraç...

Preparação de carbonos porosos por moldagem sequencial

Porous carbons have received great attention because of their potential use as adsorbents, sensors, catalytic supports and others. Among the available methods for preparing these solids, the sequential templating emerges as an efficient way to tail carbon materials, with large specific surface areas, high porosity, controlled narrow pore size distribution and different functional groups. The template process is...

Nanotecnologia: aspectos gerais e potencial de aplicação em catálise

In recent years nanomaterials, such as metallic nanoparticles, nanowires, nanotapes, nanotubes and nanocomposites, have attracted increasing interest for several technological applications. In catalysis, the great potential of nanomaterials is related to the high catalytic activity exhibited by these materials as a function of the high surface/volume ratio when the particles acquire diameter below 5 nm. In this...

A spectroscopic study of Au/CeX Zr1-X O2 catalysts

The nature of gold species in Au/CeX Zr1-X O2 catalysts was successfully investigated using the visible and near infrared photoacoustic spectroscopy and Fourier transform infrared spectroscopy of adsorbed carbon monoxide. It was found that the visible and near infrared photoacoustic spectroscopy is a powerful technique for investigating the changes of gold particle size due to addition of zirconium and the oxid...
