In the design of superconducting magnet elements, such as may be required to guide and focus ions in a particle accelerator, one frequently premises some particular current distribution and then proceeds to compute the consequent magnetic field through use of the laws of Biot and Savart or of Ampere. When working in this manner one of course may need to revise frequently the postulated current distribution before arriving at a resulting magnetic field of acceptable field quality. It therefore is of interest to consider an alternative ( inverse'') procedure in which one specifies a desired character for the field required in the region interior to the winding and undertakes then to evaluate the current distribution on the specified winding surface that would provide this desired field. We may note that in undertaking such an inverse procedure we would wish, on practical grounds, to avoid the use of any double-layer'' distributions of current on the winding surface or interface but would not demand that no fields be generated in the exterior region, so that in this respect the goal would differ in detail from that discussed by other authors, in analogy to the distribution sought in electrostatics by the so-caged Green's …

The HB-Line building vacuum instrumentation and glovebox vacuum instrumentation at the Savannah River Plant are described. The configuration and operation of the Foxboro 834 series transmitters and Moore 350 series controllers is detailed. In particular, the uncertainties in the differential pressure readings are explained.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

This report summarizes work performed for the Atomic Vapor Laser Isotope Separation (AVLIS) program from January through July, 1992. Each of the tasks assigned during this period is described, and results are presented. Section I details work on sensitivity matrices for the UDS relay telescope. These matrices show which combination of mirror motions may be performed in order to effect certain changes in beam parameters. In Section II, an analysis is given of transmission through a clipping aperture on the launch telescope deformable mirror. Observed large transmission losses could not be simulated in the analysis. An EXCEL spreadsheet program designed for in situ analysis of UDS optical systems is described in Section III. This spreadsheet permits analysis of changes in beam first-order characteristics due to changes in any optical system parameter, simple optimization to predict mirror motions needed to effect a combination of changes in beam parameters, and plotting of a variety of first-order data. Optical systems may be assembled directly from OSSD data. A CODE V nonsequential model of the UDS optical system is described in Section IV. This uses OSSD data to build the UDS model; mirror coordinates may thus be verified. Section V summarizes observations of relay …

Since its inception in 1990, the IEEE Storage System Standards Working Group has identified storage-system management as an area in need of further development The pressing need for standards in storage-system management arises from the requirement to exchange management information and to provide control in a consistent predictable manner between the components of a storage system. An appropriate set of management standards will allow multiple vendors to supply storage management subsystems or applications that are integral to or compatible with new storage systems conforming to future IEEE standards. An early, practical application of IEEE storage-system-management work is being pursued at the National Storage Laboratory (NSL), a recently-formed industrial collaboration at Lawrence Livermore National Laboratory. The NSL`s purpose is to develop advanced hardware and software technologies for high-performance, distributed storage systems. Since storage system management is of critical concern, it is being explored in depth at the NSL. Work was initiated to define basic management requirements and develop generalized graphical-user-interface tools using remote-procedure-call mechanisms to implement the NSL`s conceptual management framework. Several constraints were imposed on the development of early versions of this work to maintain compatibility with the NSL`s underlying UniTree-based software architecture and to provide timely prototypes and proof …

SRI International is conducting studies of the effects of liquid water at temperatures and pressures near its critical point on the behavior of coal. The present study involves the construction and operation of a cell for visual observation of the process. The cell is batch charged with a dispersion of coal particles in solvent; it is designed for continuous flow operation should that mode of operation become desirable. It can be electrically heated to 550{degree}C and can handle pressures to 5000 psi. Direct observation of individual particles takes place through a pair of diamond windows, a lens assembly, and a television monitoring system. A number of runs have been performed during this quarter, including runs with Wyodak and Illinois No. 6 coal with both water and tetralin. A video tape of two runs was submitted with a monthly report during this quarter, and a tape with four runs in included with this report. Unfortunately just as our experience with the cell was developing, one of the diamonds cracked and the replacement is not expected before December. Accordingly we have spent some time operating the cell with a single window and front lighting.

We have characterized certain Human Specific Alu Insertions as either dimorphic (TPA25, PV92, APO), sightly dimorphic (C2N4 and C4N4) or monomorphic (C3N1, C4N6, C4N2, C4N5, C4N8), based on studies of Caucasian, Asian, American Black and African Black populations. Our approach is based upon: (1) PCR amplification using primers directed to the sequences that flank the site of insertion of the different Alu elements studied; (2) gel electrophoresis and scoring according to the presence or absence of an Alu insertion in one or both homologous chromosomes; (3) allelic frequencies calculated and compared according to Hardy-Weinberg equilibrium. Our DNA fingerprinting procedure using PCR amplification of dimorphic Human Specific Alu insertions, is stable enough to be used not only as a tool for genetic mapping but also to characterize populations, study migrational patterns and track the inheritance of human genetic disorders.

The upgrade to the DECstation 3100 (and other workstations underway) has enabled the use of more sophisticated electronic structure methods. Research were done in the following fields: tris(cyclopentadienyl) actinide complexes; actinide-containing molecules with metal-metal bonds (U dimer, Th-Ru, Zr-Ru); and applications of fully relativistic DV-X{alpha} method to trivalent actinide chemistry (MCl{sub 3}).
