Crossing the Curatorial Chasm - Lessons from the FACADE project
4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PresentationsDate: 2009-05-19 01:00 PM – 02:30 PMThe FACADE project was tasked with developing a preservation strategy and program for proprietary, complex 3D CAD models used in architecture and design. In achieving this goal, the project created an expressive object model as an RDF ontology, wrote numerous curatorial applications to assist project comprehension and metadata creation, devised techniques for processing collections at large scale, and designed compelling visualization and discovery user interfaces. Actual instance collections were ingested into DSpace, and UIs manifested from them.Institute of Museum and Library Service
Analysis of a char-forming ablator
The purpose of this thesis is to conduct an analytical analysis of a char-forming ablation material. This is one phase of ablation heat transfer.
Fourier\u27s general equation for one dimensional heat conduction is transformed to moving coordinates and is then solved using the applicable boundary conditions. Solutions of this equation are valid for initial studies in ablation heat transfer --Abstract, page ii

Synthesis and Catalytic Activity of -NHC Group 9 Metal Pincer Complexes
N-Heterocyclic carbenes (NHCs) are one of the few ligand systems that can finely tune transition metal catalysts via sterics and electronics. The strong sigma-donating properties of these ancillary ligands allow the development of robust tridentate NHC pincer framework, which has emerged as an alternative to the phosphine pincer ligands. The combination of NHC and pincer systems has resulted in a new generation of catalytically active organometallic complexes reported throughout the literature. -NHC Rh pincer complexes were found to be catalytically active in C-C and C-B bond formation via 1,4dition reactions. In addition, the in-situ generated -NHC Ir(H) pincer complex demonstrated catalytic activity in borylation of arene C-H bonds. Preliminary results are comparable to the C-H borylation results published by Hartwig and co-workers. The -NHC Ir(H) pincer complex may also prove to be a suitable catalyst for alkane dehydrogenation, due to framework similarities of the highly active and durable PCP and POCOP pincer hydride systems. Expansion of group 9 metal sources for transmetalation of the -NHC Zr pincer complex afforded the development of -NHC Rh(CO) and -NHC Co complexes. Group 9 metal carbonyl complexes have been reported as active catalysts in photocatalytic C-H activation of small molecules. Testing of Co sources for transmetalation afforded three rare Co pincer complexes, and the first examples of -NHC Co pincer complexes to date. Development of -NHC pincer complexes with base metals provide cost-effect alternatives to pincer systems with precious metal centers, and is reported herein
New Directions in Federal Land Use Legislation
The 1960\u27s, a decade that began with enthusiasm and ended in dashed hopes for many social planners, encompassed rising environmental expectations that did not fade with the decade, but grew stronger and contributed to several notable legislative breakthroughs. The new laws which the environmental awareness brought about were not only pollution control measures but extended to such issues as coastal zone protection, power plant siting, scenic area preservation and highway planning. The concern with protecting environmental values in land underlay the enactment of several state laws which have been referred to as a quiet revolution in land use control, a revolution that has returned land use regulatory power to the several states. Now this revolution has reached Washington where the Senate has passed legislation which would fundamentally alter governmental relationships regarding land use planning and regulation in the United States. Objectives which writers on urban and social problems have long advocated, but which the constituency for planning and housing has never been able to effectuate, stand a fair chance of achievement under the environmental aegis, as O\u27Harrow apparently anticipated
