theoretical work ... ; Dose, who worked at the laboratory in Detmold, had spent
considerable time on photoelestic work ... He has investigated in particular the
stress distribution in a cantilever beam with large circular out-outs ... ;
Wooden construction The firm had concentrated on the development of laminated
construction initially of the form of Buche or Breche, 0.5 mm thick ... ; The
use of plastics The most outstanding example of the use for load-bearing
