A canábis foi proibida pelos seus efeitos psicotrópicos, graças a uma campanha destinada a servir interesses pouco claros. E, assim, a mesma planta que, três milénios antes de Cristo, já era utilizada na China para produzir chás medicinais – e que viria a fornecer velas e cabos quase indestrutíveis aos navegadores portugueses – tornava-se ilegal, passando a ser encarada como uma droga infame, capaz de levar os jovens à loucura e morte... Mais recentemente, porém, a legalização da canábis começou a ser reclamada por uma parte considerável da sociedade graças às suas múltiplas virtudes e usos, sendo a dimensão psicotrópica apenas um deles. Ao longo destas páginas, viaj...

Women's Cinema in Contemporary Portugal brings together scholars from Portugal, UK and the USA, to discuss 14 women film directors in Portugal, focussing on their production in both feature film and documentary genres over the last half-century.

The history of Portuguese women's cinema only begins systematically after the 1974 r...
The book "Biodiesel: Feedstocks and Processing Technologies" is intended to provide a professional look on the recent achievements and emerging trends in biodiesel production. It includes 22 chapters, organized in two sections. The first book section: "Feedstocks for Biodiesel Production" covers issues associated with the utilization of cost effective non-edible raw materials and wastes, and the development of biomass feedstock with physical and chemical properties that facilitate it processing to biodiesel. These include Brassicaceae spp., cooking oils, animal fat wastes, oleaginous fungi, and algae. The second book section: "Biodiesel Production Methods" is devoted to the advanced techniques for biodiesel synthesis: supercritical transesterification, microwaves, radio frequency and ultrasound techniques, reactive distillation, and optimized transesterification processes making use of solid catalysts and immobilized enzymes. The adequate and up-to-date information provided in this book should be of interest for research scientist, students, and technologists, involved in biodiesel production.
