Sub-scale Flight Testing (SFT) is potentially useful in predicting aircraft flight behaviour, especially in the case of unconventional designs for which legacy information is unavailable and wind tunnel tests are unable to predict aircraft dynamics. A necessary condition for SFT is the design of properly …

BACKGROUND: Instability of the knee joint during gait is frequently reported by patients with knee osteoarthritis or an anterior cruciate ligament rupture. The assessment of instability in clinical practice and clinical research studies mainly relies on self-reporting. Alternatively, parameters measured …

Sharks are ecological important inhabitants of most of the world’s oceans and seas. Still their life-history, which is dictated by slow growth rates and late maturity, makes most species, especially demersal- and coastal sharks, prone to exploitation through target- and nontarget fisheries. Another threat …

Salt marsh stability from 10 different salt marshes was studied in the Dutch Wadden Sea region and the Scheldt Estuary during October and November 2018. This report elaborates how salt marsh stability is influenced by bioturbation of Orchestia sp., grazing of large herbivores and different soil and plant …
