Toxicity of Nanoparticles in Plants: An Evaluation of Cyto/Morpho-physiological, Biochemical and Molecular Responses, Volume Five in the Nanomaterial-Plant Interactions series, reviews the latest research on toxicological effects of using nanotechnology in plants. Key themes include analyzing plant exposure to nanomaterials, mechanisms of toxicity of nanoparticles to plants, and effects, uptake and translocation of various different nanoparticles. This will be an essential read for any scientist or researcher looking to assess and understand the potential toxicological risks associated with plant nanotechnology. To date, nanotechnology is considered one of the most promising areas of research due to the widespread applications of nanomaterials in plant science and agriculture. However, extensive use of nano-based products raises concerns regarding their toxicity in crop plants, their environmental impact and potential consequences to humans via the food chain.

This book constitutes the refereed proceedings of the 10th European Conference on Technology Enhanced Learning, EC-TEL 2015, held in Toledo, Spain, in September 2015.

Die Autoren stellen die Sicherheitsaspekte der Internet-Kommunikation verst ndlich dar. Dabei betrachten sie nicht nur die theoretischen Grundlagen verschiedener Sicherheitsstrategien, sondern erl utern auch die Risiken bei der Anwendung bzw. Implementierung. Die beschriebenen Sicherheitstools orientieren sich am Schichtenmodell der ISO/OSI, die Sicherheitsrelevanz der verschiedenen Schichten wird analysiert. Erl uterungen von Security-Aspekten bei der IP-Telefonie und beim Internet-Banking runden das Buch ab.
