CATULLUS 8: ARIDA ... PUMICE EXPOLITUM?

Pumice-pumice collisions and the effect of the impact angle

[1] Using a high-speed video camera, we studied oblique collisions of lapilli-size pumice cylinders (with no rotation before impact) on flat pumice targets. Our results show that the rebound angle, the ratios of the components of velocities and the energy loss vary with the impact angle. In particular, in collisions with an average yaw angle approximately equal to zero, we observed relatively l...

Catullus, Ennius, and the Poetics of Aui^sion'

earlier Latin literature; they adopted instead the manner and the matter of Alexandrian poetry, particularly of Callimachus. They wrote urbane short poems and recondite epyllia; they made use of Greek words in transliteration and of learned allusions after the manner of the Alexandrians; they polished the hexameter to such a degree that Catullus, in poem 64, shows not a single violation of Herm...

The Impermanent Text in Catullus and Other Roman Poets

To us, who have lived our entire lives in a culture saturated with print, it seems obvious that the survival of a verbal artifact for any length of time would be impossible without material texts. To a writer, getting published is the necessary first step toward a potentially limitless Nachleben. The fact that, ceteris paribus, a new book is more likely to be pulped within a few years than to s...

Pumice Aggregates for Internal Water Curing

A novel concept in internal curing of High Performance Concrete is based on dispersing very small, saturated lightweight aggregates (LWA) in the concrete, containing sufficient water to counteract self-desiccation. With this approach, the amount of water in the LWA can be minimized, thus economizing on the amount of the LWA. In this study, the pore structure of different size fractions of pumic...
