Species of the genus Hydra show no senescence and have the potential for extremely long life spans. Previous studies have demonstrated both constant mortality under constant laboratory conditions and instances of high mortality under specific environmental conditions.

Research has three kinds of results: things, ideas, and heartbreak. Things include the discovery of new atomic particles, the synthesis of a new drug, and the determination of a new agent that is effective in treating or preventing a disease (eg, azidothymidine for the treatment of the acquired immunodeficiency syndrome).

This chapter describes the design for High-performance Data Recording Architecture (HYDRA). Presently, digital continuous media (CM) are well established as an integral part of many applications. In recent years, a considerable amount of research has focused on the efficient retrieval of such media for many concurrent users.

1. The indifferent interstitial cells divide by mitosis. 2. This mitosis occurs within the nuclear area but not inside the nuclear membrane. 3. Centrioles are present and appear to be enclosed within the nuclear membrane during the early telephase. 4.

Hydra were cut so that regenerates consisting only of the central gastric region were formed. This region, which has no natural opening to the environment, is capable of osmoregulation and of removing excess fluid from the gut. The fluid is excreted through a break in the body wall created as a result of a strong contraction when the gut is distended ...

This paper describes the design philosophy of HYDRA—the kernel of an operating system for C.mmp, the Carnegie-Mellon Multi-Mini-Processor. This philosophy is realized through the introduction of a generalized notion of “resource,” both physical and virtual, called an “object.” Mechanisms are presented for dealing with objects, including the creation of
