In reinforced concrete flat slab buildings, the transference of unbalanced moments in the slab?column connections usually results from the asymmetry of spans, vertical loads, and horizontal forces from the wind. The punching strength of the slab?column c...

Helicopter and turboprop engines are susceptible to the ingestion of debris and other foreign objects, especially during take-off, landing, and hover. To avoid deleterious effects, filters such as Inlet Particle Separators (IPS) can be installed. However...
