|
 | Metastable excited nuclear states, isomers, have been of strong interest for decades, with studies motivated by their physical properties and the promise of high-energy-density applications. Much research has concentrated on induced depletion processes as a potential means of controlling the release of energy stored in these isomers. This research comprises a very specialized sub-field of nuclear physics and, as such, has often suffered from a lack of connection with the ... |

| Metastable excited nuclear states, isomers, have been of strong interest for decades, with studies motivated by their physical properties and the promise of high-energy-density applications. Much research has concentrated on so-called triggered gamma emission as a means of controlling the release of energy stored in these isomers. This research comprises a very specialized sub-field of nuclear physics and, as such, has often suffered from a lack of connection with the ... |

|
| Nuclear isomers can store tremendous amounts of energy for long times - for example, the 31-year metastable excited state of (178)(subm2)Hf stores 2. 445 MeV per nucleus, or 1.2 GigaJoules per gram. These special states of certain isotopes may therefore prove useful as nuclear batteries, provided that a means is found by which to control (trigger) their energy release upon demand. The concentration of current research is on the use ... |

|
| Nuclear isomers can store tremendous amounts of energy for long times and the prospects for a controlled "clean" release of this energy for applications have motivated considerable research. Significant insight into nuclear structure also results from studies of reactions that may cause a triggered energy release. The primary emphasis has been on reactions induced by externally-produced photons. These studies comprise a very narrow sub-field of nuclear physics that has often ... |

|
| Youngstown State University's Isomer Physics Project is a program of basic physics research with the goal of providing credible, high-quality measurements and theoretical analysis related to achieving a controlled release of energy stored in nuclear isomers. An emphasis has been on providing a firm foundation coupling traditional nuclear structure research, such as in spectroscopic studies, with focused triggering experiments. As such, success is defined not by proving or disproving specific ... |

| Nuclear isomers can store tremendous amounts of energy for long times for example, the 31- year metastable excited state of .178m2Hf stores 2.445 MeV per nucleus, or 1.2 GigaJoules per gram. These special states of certain isotopes therefore may prove useful as nuclear batteries, provided that a means is found by which to control (trigger) their energy release upon demand.

| Enzyme Mini-Test for Field Identification of Leishmania Isolates from U. S. Military Personnel |

|
 | It is possible to identify Leishmania isolates by cellulose acetate electrophoresis (CAE) of up to 29 enzyme activities. Certain of these enzymes are polymorphic within a subspecies and therefore of limited value for identification; others are monomorphic and have taxonomic significance. Once large numbers of isolates from various geographical areas have been characterized and monomorphic enzymes identified, a simple, rapid, accurate field type identification test can be devised. |
