Uso de biomassa como absorvente para a contenção de derramamento de óleo

Neste trabalho foi investigada a capacidade de absorção de óleos de diferentes tipos de absorventes e comparada com a de um absorvente vegetal comercial. Os resultados mostraram que vários absorventes testados apresentaram capacidade de absorção superior à do absorvente comercial, sendo que a salvínia sp. apresentou capacidade significativamente superior. O tamanho das partículas da salvínia sp. influenciou nacapacidade de absorção dos óleos

Nanosatellites: Space and Ground Technologies, Operations and Economics

Nanosatellites: Space and Ground Technologies, Operations and Economics comprehensively presents the latest research on the fast-developing area of nanosatellites. Divided into three distinct sections, the book begins with a brief history of nanosatellites and introduces nanosatellites technologies and payloads, also explaining how these are deployed into space. The second section provides an overview of the ground segment and operations, and the third section focuses on the regulations, policies, economics, and future trends. Key features: Payloads for nanosatellites Nanosatellites components design Examines the cost of development of nanosatellites. Covers the latest policies and regulations. Considers future trends for nanosatellites. Nanosatellites: Space and Ground Technologies, Operations and Economics is a comprehensive reference for researchers and practitioners working with nanosatellites in the aerospace industry
