Hydropneumatic suspension systems combine the excellent properties of gas springs with the favourable damping properties of hydraulic fluids. The advantages of these systems are particularly appropriate for mobile applications, such as agricultural and construction equipment as well as passenger cars, trucks and busses. Based on his 20 years of experience with this technology, Dr. Bauer provides in this book an extensive overview of hydropneumatic suspension systems. Starting with a comparison of different types of suspension systems, the author subsequently describes the theoretical background associated with spring and damping characteristics of hydropneumatic systems. Furthermore, he explains the design of the most important system components and gives an overview of level control systems, various special functions, patents and design examples. Finally, an outlook for future hydropneumatic suspension systems is discussed. Compared to the first edition, this new editionputs an additional focus on damping functions as well as applications / projects and contains various additional details such as proportional valves, all-wheel suspension or dediated power supply. Furthermore, suspension testing has been added as a new chapter.

One night in April 2014, members of the terrorist organization Boko Haram raided the small town of Chibok in northeast Nigeria and abducted 276 young girls from the local boarding school. The event caused massive, international outrage. Some of the girls were able to escape and award-winning journalist Wolfgang Bauer spent several weeks with them as they recounted their ordeal. In Stolen Girls, he gives voice to these girls, allowing them to speak for themselves - about their lives before the abduction, about the horrors during their captivity, and their dreams of a better future.

Award-winning journalist Wolfgang Bauer and photographer Stanislav Krupar were the first undercover reporters to document the journey of Syrian refugees from Egypt to Europe. Posing as English teachers in 2014, they were direct witnesses to the brutality of smuggler gangs, the processes of detainment and deportation, the dangers of sea-crossing on rickety boats, and the final furtive journey through Europe. Combining their own travels with other eyewitness accounts in the first book of reportage of its kind, Crossing the Sea brings to life both the systemic problems and the individual faces behind the crisis, and is a passionate appeal for more humanitarian refugee policies.
