Case Histories Of Specialized Turbomachinery Problems

PaperPg. 33-50.Vibration problems in turbomachinery occur due to many factors. Some of the problems could have been prevented if more detailed design analyses were performed. Other times the problems occur due to design extrapolations which are pushing the state of the art. The case histories of excessive vibrations and failures that will be discussed in this presentation are examples of those where additional design analyses would not necessarily have predicted or anticipated the problem that occurred because the analytical models are not sufficient to take into account all the variables

The Disclosure of Gay and Lesbian Sexual Identities and Relational Outcome Uncertainties

The purpose of this study was to analyze the change in gay/lesbian friendships after the disclosure of their sexual identity. Six specific areas were examined: (1) what are the circumstances under which persons find out their close friends are gay/lesbian (hereafter referred to as the event), (2) do relationships change when close friends find out about the participants' sexual identity, (3) if the relationship changes, how does it change (hereafter referred to as the relational outcome), (4) which events are associated with which relational outcomes, (5) how satisfied are the gays/lesbians with their relational outcomes, and (6) what are the gays'/lesbians' perceived causes of the relational outcomes. The results of this study indicated that the majority of the participants disclosed their sexual identity to their close friends. And they did so in an attempt to be honest, to avoid hiding who they are, and to be able to talk about their sexual identity freely. Most of the participants reported being quite satisfied with the relationships which became more close or stayed the same. Most of the participants reported being somewhat unsatisfied with the relationships which became more distant or terminated. The way in which the friends found out about the participants' sexual identity was not related to whether or not the relationship became more close or more distant. The participants believed their relationships became more close because they were honest. However, the participants believed their relationships became more distant because their friends were homophobic. This research is significant because it may help counselors, therapists, and practitioners coach gay men and lesbians when their relationships deteriorate or are strained. This research may also enable gay men and lesbians to be aware of potential factors which might affect their relationships with their friends after disclosure occurs. In addition, this research may equip gay men and lesbians with information to enable them to make educated decisions on discussing their sexual identity with their friends. Furthermore, the results from this research might provide suggestions to individuals who have gay friends to help them make the coming-out process easier for their gay friends

Chemical Compatibility Testing Final Report Including Test Plans and Procedures

This report provides an independent assessment of information on mixed waste streams, chemical compatibility information on polymers, and standard test methods for polymer properties. It includes a technology review of mixed low-level waste (LLW) streams and material compatibilities, validation for the plan to test the compatibility of simulated mixed wastes with potential seal and liner materials, and the test plan itself. Potential packaging materials were reviewed and evaluated for compatibility with expected hazardous wastes. The chemical and physical property measurements required for testing container materials were determined. Test methodologies for evaluating compatibility were collected and reviewed for applicability. A test plan to meet US Department of Energy and Environmental Protection Agency requirements was developed. The expected wastes were compared with the chemical resistances of polymers, the top-ranking polymers were selected for testing, and the most applicable test methods for candidate seal and liner materials were determined. Five recommended solutions to simulate mixed LLW streams are described. The test plan includes descriptions of test materials, test procedures, data collection protocols, safety and environmental considerations, and quality assurance procedures. The recommended order of testing to be conducted is specified
