1. Wind-induced vibrations in tall timber buildings : Design standards, experimental and numerical modal analyses
Sammanfattning : Climate change and densification of cities are two major global challenges. Inthe building and construction industry, there are great expectations that tall timberbuildings will constitute one of the most sustainable solutions. First, verticalurban growth is energy and resource-efficient. LÄS MER
2. Female choice and paternal care in the fifteen-spined stickleback, Spinachia spinachia
