It was found that there was a strong dependence of the density profile on the secondary air injection location and that there was a pronounced solid separation from the conveying gas, due to the swirl motion. Furthermore, the swirl motion generated strong internal circulation patterns and higher slip velocities than in the case of nonswirl motion as in an ordinary circulating fluidized bed. Radial solids flux profiles were measured at different axial locations. The general radial profile in a swirling circulating fluidized bed indicated an increased downward flow of solids near the bed walls, and strong variations in radial profiles along the axial height. For swirl numbers less than 0.9, which is typical for swirling circulating fluidized beds, there is no significant increase in erosion due to swirl motion inside the bed. Pending further investigation of swirl motion with combustion, at least from our cold model studies, no disadvantages due to the introduction of swirl motion were discovered.

Progress is identified in the following items reported as significant findings for the January 1993 reporting period: In Task 2, revisions to the dewatering topical report were started. In the Task 6 froth flotation work, Pittsburgh seam minus 28 mesh size and specific gravity analyses are complete, and analysis for the 100 mesh tests continued. Illinois No. 6 testing continues. In the Task 6 Coal Liberation work, ash analysis of 134 different composition/size fractions produced by the crushing of the 6M [times] 8M sample were completed.

In order to be able to explore the control of cell wall polysaccharide synthesis at the molecular level, which inter alia might eventually lead to means for useful modification of plant biomass polysaccharide production, the immediate goals of this project are to identify polypeptides responsible for wall polysaccharide synthase activities and to obtain clones of the genes that encode them. We are concentrating on plasma membraneassociated (1,3)-{beta}-glucan synthase (glucan synthase-II or GS-II) and Golgi-associated (1,4)-{beta}-glucan synthase (glucan synthase-I or GS-I), of growing pea stem tissue. Our progress has been much more rapid with respect to GS-II than regarding GS-I.

Funeral program for Mrs. Dorothy Word Straughter, born March 5, 1910. The funeral was held March 20, 1993 at Second Baptist Church, officiated by Rev. Grant M. Hawkins.

Math and Science School is a program designed to enrich and encourage elementary students and teachers of the Confederated Tribes of the Umatilla Indian Reservation in the areas of mathematics and science activities. By providing access to special hands-on workshop sessions held in the mobile science laboratory at the school sites during the school year for students and teachers and with a separate summer inservice program for students, elementary children and teachers are encouraged to explore the fascination of science and the utility of mathematics through use of integrated curricula. The Department of Energy grant underwrites the instructional costs of this system while the grantee provides the mobile laboratory and the majority of the materials.
