The development of professional education for social work at the Raymond A. Kent School of Social Work of the University of Louisville, 1918-1946.

It would be impossible to single out any individual or group and give credit tor the development of the Raymond A. Kent School of Social Work. There are names which bring to mind real achievement and tremendous effort in the field which they had chosen and to which they had dedicated their service; names which lived through years of discouragement and disillusionment; names which perhaps have been forgotten with the passage of time but played vital roles in different periods of the development of the school. This, therefore, is not an account of things happening, but in reality, an account of the efforts of real persons with foresight and a faith in a goal

Engineering calculations for communications satellite systems planning

A procedure is described that was used to calculate minimum required satellite separations based on total link carrier to interference requirements. Also summarized are recent results with a switching algorithm for satellite synthesis problems. Analytic solution value bounds for two of the satellite synthesis models studied are described. Preliminary results from an empirical study of alternate mixed integer programming models for satellite synthesis are presented. Research plans for the near future are discussed

Engineering calculations for the Delta S method of solving the orbital allotment problem

The method of calculating single-entry separation requirements for pairs of satellites is extended to include the interference on the top link as well as on the down link. Several heuristic models for analyzing the effects of shaped-beam antenna designs on required satellite separations are introduced and demonstrated with gain contour plots. The calculation of aggregate interference is extended to include the effects of up-link interference. The relationship between the single-entry C/I requirements, used in determining satellite separation constraints for various optimization procedures, and the aggregate C/I values of the resulting solutions is discussed

Groundwater arsenic in central Thailand

Arsenic is a naturally occurring dissolved element in ground and surface waters throughout the world. Longterm exposure to trace levels of arsenic causes chronic skin and cardiovascular disease. It is also a suspected carcinogen and mutagen. Skin lesions, cancers, and cardiovascular diseases are traceable to arsenic poisoning (Jones 2000). The Ganges delta in Bangladesh and West Bengal are now well known to have very high levels of arsenic. Many other regions are also becoming aware of the presence of this element at levels damaging to health

RNA promotes phase separation of glycolysis enzymes into yeast G bodies in hypoxia.

In hypoxic stress conditions, glycolysis enzymes assemble into singular cytoplasmic granules called glycolytic (G) bodies. G body formation in yeast correlates with increased glucose consumption and cell survival. However, the physical properties and organizing principles that define G body formation are unclear. We demonstrate that glycolysis enzymes are non-canonical RNA binding proteins, sharing many common mRNA substrates that are also integral constituents of G bodies. Targeting nonspecific endoribonucleases to G bodies reveals that RNA nucleates G body formation and maintains its structural integrity. Consistent with a phase separation mechanism of biogenesis, recruitment of glycolysis enzymes to G bodies relies on multivalent homotypic and heterotypic interactions. Furthermore, G bodies fuse in vivo and are largely insensitive to 1,6-hexanediol, consistent with a hydrogel-like composition. Taken together, our results elucidate the biophysical nature of G bodies and demonstrate that RNA nucleates phase separation of the glycolysis machinery in response to hypoxic stress
