    Notes: [Auszug] JUDGING from Mr. Kingsmill's photograph, it would appear that the bird is just in the position of the half-stroke of the wings when making a fresh start or a sudden spurt. While these birds generally sail about, yet at times they do flap their wings. The movement of the wings in all these ...

    Notes: [Auszug] WHILE photographing insects lately in the hills above Pegli (Italy), I was much struck by the curious way in which many of the butterflies turned and shifted their position after they had settled, their apparently eccentric behaviour making it difficult to obtain a good picture. It suddenly ...

    Notes: Abstract The newly derived dynamic-crack-branching criterion with its modifications is verified by the dynamicphotoelastic results of dynamic crack branchings in thinpolycarbonate, single-edged crack-tension specimens. Successful crack branching was observed in four specimens and unsuccessful branching in another. Crack branching consistently occurred when the necessary conditions ofK I =K I b =3.3 MPa $$\sqrt m$$ and the sufficiency condition ofr o =r c =0.75 mm were satisfied simultaneously. In the unsuccessful branching test, the necessary condition was not satisfied sinceK I was always less thanK I b .
