11. The operating life of a zinc air cell is a critical function of its interaction with its environment. 12. Graebe began developing the ROHO dry flotation technology of inter-connected air cells to mimic the properties of water. 13. While these batteries are obsolete, modern replacements include the Wein zinc-air cell PX625, available at large online retailers. 14. As a result, they are more susceptible to infection and have fewer alveoli, or air cells , in their lungs. 15. Interrogations are continuing at Guantanamo Bay, Cuba, where 300 al-Qaida and Taliban prisoners are being held in open-air cells . 16. This new and larger facility replaced Camp X-Ray, a warren of open-air cells resembling dog kennels several miles west. 17. The furniture, designed by Jan Dranger, uses a system of air cells , like the individual compartments in a dirigible. 18. Behind three fences and coils of razor wire, prisoners with shaved heads and orange jumpsuits sat in open-air cells . 19. At its upper edge are some broken air cells which are closed in by the ethmoid and lacrimal bones. 20. Li-air cell performance is limited by the efficiency of reaction at the cathode because most of the voltage drop occurs there.
