 | The United States faces a potential transition in the balance of power and a growing concern over the threat of nuclear proliferation. The bipolar balance of power during the Cold War, though often tense and dangerous, kept states in check, thus maintaining a relatively stable international security environment with limited, or at least controlled, proliferation of nuclear technology. The current focus on the dynamics of international power, the threat of ... |

| The United States has long been dependent on foreign oil and foreign energy sources. The Energy Independence and Security Act of 2007 (EISA 2007) identified multiple areas in which the United States should focus to become more energy independent. Throughout the course of the historic 2008 Presidential primaries and Presidential campaign, one of the common themes and promises from each candidate was to set a course for the United States ... |

|
 | After 25+ years of satisfactory operation, a potential problem with the cold-service vessels of Du Pont Sabine River Works (SRW) Ethylene Plant was recognized. A program was instituted to identify, evaluate, and, subsequently, correct low temperature ductility problems with vessels operating below 0 C (32 F) that could result in a catastrophic failure. The integrity of the suspected vessels at low temperatures was evaluated using field metallographic and replication techniques, ... |

|
| A number of techniques, such as elemental analysis, molecular weight determination, UV and IR absorption spectra, conductivity measurements and phosphorescence intensities were employed to determine the composition and structure of the europium, terbium and neodymium complexes of dimethylacetamide (DMAC) in both the solid state and in DMAC solutions. From the data obtained it was concluded that DMAC acts as a bidentate ligand; coordinating to the rare- earch ion through both ... |

|
| The results of a series of phosphorescence lifetime and intensity measurements on rare-earth coordination compounds are given and discussed. Enhanced phosphorescence has been observed in scrupulously anhydrous systems and the means of preparing such salts is described. The role of ligand vibrations in influencing nonradiative decay from excited levels is analyzed. Experiments with europium(III) in selenium oxychloride have lead to a hypothesis that it is critical to enhance nonradiative decay ... |
