1. Dynamic principles in craniofacial surgery. Expander elements in craniofacial surgery
Abstract : Lannelongue & Lane described strip removal of ossified skull sutures in craniosynostosis in the 1890s. More complex osteotomies with bone grafting were developed during the 1960s. Dynamic techniques, utilizing force to direct the growing brain for skull reshaping was introduced by Jane 1978 with the p-plasty for sagittal synostosis. READ MORE

2. Thermodynamic Cycles for Low- and High-Temperature Waste Heat Recovery from Heavy-Duty Engines
Abstract : To reduce the environmental impact of heavy-duty vehicles, it is critical to reduce their CO2 emissions by improving the engine efficiency. A promising way to do this is by extracting waste heat from the engine during operation and converting it into useful work. READ MORE

4. Waste Heat Recovery from Combustion Engines based on the Rankine Cycle
Abstract : Most of the energy in the fuel burned in modern automotive internal combustion engines is lost as wasteheat without contributing to the vehicle’s propulsion. In principle some of this lost energy could becaptured and used to increase the vehicle’s fuel efficiency by fitting a waste heat recovery system to theengine. READ MORE
