and are contacted with concave arcs of the pentagonal covers, each pentagonal cover and the middle included angle and the large corners surrounding the pentagonal cover are formed commonly to form a plane, so as to form 12 faces; any face can be overturned through the screws on the pentagonal...
Although the majority of designs applied conventional cone loudspeakers to the surface faces of the solid, other designs such as the horn loading technique suggested by Goussios [6] have also been developed. The geometry of a dodecahedron is based on three spheres, the circumsphere, midsphere ...
Because of its flexibility, the framework assembled by ligand 3d is slightly sagged (Figure 5B) so that all Npyridine-Pd(II)-Npyridine angles involved in triangle and pentagon faces are adjusted to be around 90°, an ideal angle for Pd(II) square planar geometry (Figure 5C). The diameter...

What is less known, however, is that a complementary object displaying 12 faces and 20 edges called a 'dodecahedron' can be produced in huge amounts during certain adenovirus replication cycles. The decahedron was first described more than 50 years ago in the human adenovirus (HAdV3) viral ...
It is assumed that the paper faces remain rigid during deformations; that is, they do not store any energy. Then, we only estimate the fold elastic energy UcreaseUcrease of one crease by parameterizing its torsional stiffness kk, the rest crease angle 𝛾0γ0, and the opening angle 𝛾...
