The FY1997 agriculture appropriations act (P.L. 104-180) was signed into law on August 6, 1996. P.L. 104-180 provides $52.84 billion in FY1997 budget authority for the U.S. Department of Agriculture and related agencies, an amount which is $5.60 billion below the Administration's FY1997 request and $10.25 billion below the FY1996 enacted level. Much of the reduction in funding from FY1996 levels is attributable to an $8.9 billion reduction in the reimbursement for net realized losses of the Commodity Credit Corporation, which is the funding mechanism for USDA's commodity programs. The act also requires recipients of the new farm bill-authorized market transition payments to use eligible land for farm production, or place it in a conserving use.

The UCSD/TEXTOR collaboration has achieved the completion of three major tasks this year: (1) pump limiter studies; (2) RI-mode turbulence studies; and (3) velocity shear stabilization of turbulence. Brief summaries of progress in each area are given.

The focus of this work is the production of 2-mm P{alpha}MS mandrels by microencapsulation for use as National Ignition Facility (NIF) laser targets. It is our findings thus far that the processing techniques used previously for the 0.5-mm and 1.0-mm targets are no longer useful for preparation of the larger targets for a few fundamental reasons. The driving force for sphericity (from the minimization of interracial energy) decreases as the radius of curvature increases. Simultaneously, the mechanical robustness /stability of the water-oil-water emulsion droplets decreases as the droplet size increases. The impact of these physical conditions and the possibilities of circumventing these limitations have been examined while attempting to meet the NIF shell power spectrum criteria. Identifying the key parameters in the transition (solidification) from a w-o-w droplet to a solid polymer shell has been understood implicitly to be the paramount goal. It is believed through the knowledge gained that it will be possible to minimize the deleterious forces and maximize shell sphericity. At this point it is believed that properties intrinsic to the polymer (i.e., P{alpha}MS) such as its solution behavior and evolution of film stresses control the overall shell sphericity.
