There is convincing evidence from the study of nuclear stabilities, magnetic moments, spins, and from other sources, that there is a marked regularity of nuclear properties, particularly clearly shown by breaks at 2, 8, 20, 28, 50, 82 and 126 protons or neutrons.

Physical Review, 1949
The existence of closed shells in nuclei is indicated by the particular stability and abundance of nuclear systems with certain numbers of neutrons and of protons. An interesting correspondence exists between these numbers and the degeneracy of energy levels in the model of free particles in a simple rectangular potential well.

As early as 1917 Harkins (17) pointed out that nuclei with even numbers of protons or neutrons are more stable than those with odd numbers. Elsasser (33, 34) found that special numbers of protons or neutrons form particularly stable configurations. We shall list here a series of facts which indicate that we obtain especially stable nuclei when either ...

Shape-changing shell-like structures
Bioinspiration & Biomimetics, 2013Plants such as Dionaea muscipula (Venus Flytrap) can change the shape of their shell-like leaves by actively altering the cell pressures. These leaves are hydraulic actuators that do not require any complex controls and that possess an energy efficiency that is unmatched by natural or artificial muscles (Huber et al 1997 Proc. R. Soc.

Shell structure and shell strength in Cirripedes
Proceedings: Animal Sciences, 1989Compressive and adhesive strengths of 7 barnacles endemic to Bombay shore were ascertained by using Instron universal testing machine. The adhesive strengths of balanid species settled on man-made materials like bakelite, asbestos, perspex, rubber, glass and teflon were determined. The adhesion on teflon was found to be the poorest.

Summary: We derive an updated Lagrangian formulation of the generalized conforming flat shell element with drilling degrees of freedom based on the incremental equation of virtual work for a three-dimensional continuum, aiming at a purely geometric nonlinear analysis of space structures.

46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005
Daton-Lovett’s invention has been recently extended in a number of new directions, and this paper reviews recent progress in the following three main areas: (i) analytical and computational models of bistable behaviour, which provide an understanding of the underlying structural behaviour and also mathematical tools for predicting the details of ...
