Early 19th-century loving cups and similar pieces in Boston glass generally had hollow stems enclosing coins.
To Bob Benson, Pete looks like he's got it all, but this is "Mad Men," where the people who look like they have it all generally have hollow and flimsy existences.
Within the floodplain forest, both species roosted in areas that had higher densities of hollow-bearing trees than generally available; dead hollow-bearing trees for N. geoffroyi and large, live trees for C. gouldii.
But like channel-surfing on TV, screen-hopping is generally a pretty hollow experience, tending to confirm the feeling that nothing worth watching is really on.

But studying parrots in the wild is "extremely difficult" because they generally nest in hollows high in trees, says behavioral ecologist Timothy Wright of New Mexico State University in Las Cruces, an expert on wild parrots.
The hollow piers generally have thick walls (0.5 m in this case), and hence, the use of a thin shell element is not found to be suitable.
Sorbent hollow fibres, generally prepared by fully encapsulating an adsorbent within a polymer binder such as polyethersulfone (PES), provide a low pressure drop alternative to conventional packed beds.
However, the main process for the preparation of hollow spheres generally requires removable templates such as monodispersed silica, polystyrene latex spheres, metal nanoparticles, gas bubbles, and polymer spheres followed by sequential adsorption of magnetic nanoparticles on the templates [13, 14, 15, 16, 17, 18].
