Evaluation of solid-core thermal antimatter propulsion concepts

Abstract This work seeks to summarize some special aspects of a type of exoplanets known as super-Earths (SE), and the direct influence of these aspects in their habitability. Physical processes like the internal thermal evolution and the generation of a protective Planetary Magnetic Field (PMF) are directly related with habitability. Other aspects such as rotation and the formation of a solid core are fundamental when analyzing the possibilities that a SE would have to be habitable. This work analyzes the fundamental theoretical aspects on which the models of thermal evolution and the scaling laws of the planetary dynamos are based. These theoretical aspects allow to develop models of the magnetic evolution of the planets and the role played by the PMF in the protection of the atmosphere and the habitability of the planet.

Inhibited Water

Eighty-two cotton, foam, and solid core stock and custom earplugs were evaluated objectively for water absorption and water penetration characteristics in order to determine their efficacy for control of water-borne infection in ears having open middle ear cavities. Cotton plugs, even when saturated with petroleum jelly, had poor consistency in resisting even minimal water pressure. Polymeric foam plugs, especially when saturated with petroleum jelly, appeared to inhibit water flow in conditions approximating actual ear protection use. No plugs evaluated, including custom elastomeric solid core plugs, inhibited water penetration in conditions approximating shallow surface dives. A clinical protocol for evaluation of potential earplugs for patient use is proposed on the basis of this study.
