Industrial benefits and future expectations in materials and processes resulting from space technology

Space technology transfer is discussed as applied to the field of materials science. Advances made in processing include improved computer techniques, and structural analysis. Technology transfer is shown to have an important impact potential in the overall productivity of the United States

Nondestructive testing of brazed rocket engine components

Report details study made of nondestructive radiographic, ultrasonic, thermographic, and leak test methods used to inspect and evaluate the quality of the various brazed joints in liquid-propellant rocket engine components and assemblies. Descriptions of some of the unique equipment and methods developed are included

Compliance with child support orders in divorce cases

This paper examines compliance with child support orders by divorced fathers in Wisconsin. Compliance increases as the income of the father increases, although it falls in the highest income category. The "burden" of awards does not affect compliance unless more than 30 percent of income is owed. More stringent enforcement systems increase compliance. We find that most divorced fathers who are not complying with their orders do not have very low incomes, in contrast to noncomplying fathers in nonmarital cases. This suggests that the best policies to increase compliance among divorced fathers may differ from those for nonmarital fathers.

Patterns of Child Support Compliance in Wisconsin

This paper examines five-year compliance patterns among Wisconsin child support cases that came to court in 1986–88. We find only limited support for the common assumption that compliance with child support orders declines over time: the average percent paid is about .65 during each of the first five years. The most predominant trend is an increasing polarization into groups of nonpayers and full payers. Although we find considerable stability from year to year among nonpayers and full payers, there is considerable change over the course of five years. Compliance during the first year provides some indication of long-term compliance, but about half of fathers change their compliance rate over the period. We find important differences between divorced and nonmarital fathers, differences that are more pronounced than are apparent from a single year of data. Policy implications are discussed and further research is suggested.

Manufacturing process applications team (MATeam)

Activities of the manufacturing applications team (MATeam) in effecting widespread transfer of NASA technology to aid in the solution of manufacturing problems in the industrial sector are described. During the program's first year of operation, 450 companies, industry associations, and government agencies were contacted, 150 manufacturing problems were documented, and 20 potential technology transfers were identified. Although none of the technology transfers has been commercialized and put in use, several are in the applications engineering phase, and others are in the early stages of implementation. The technology transfer process is described and guidelines used for the preparation of problems statements are included

Linear response in infinite nuclear matter as a tool to reveal finite size instabilities

Nuclear effective interactions are often modelled by simple analytical expressions such as the Skyrme zero-range force. This effective interaction depends on a limited number of parameters that are usually fitted using experimental data obtained from doubly magic nuclei. It was recently shown that many Skyrme functionals lead to the appearance of instabilities, in particular when symmetries are broken, for example unphysical polarization of odd-even or rotating nuclei. In this article, we show how the formalism of the linear response in infinite nuclear matter can be used to predict and avoid the regions of parameters that are responsible for these unphysical instabilities.Comment: Based on talk presented at 18th Nuclear Physics Workshop "Maria and Pierre Curie", 2011, Kazimierz, Polan
