IN RECENT YEARS, CONSIDERABLE ATTENTION HAS BEEN FOCUSED ON THE DEVELOPMENT OF TECHNIQUES FOR GENETIC TRANSFORMATION OF HIGHER PLANTS. MOST ADVANCES HAVE BEEN MADE USING EITHER PETUNIA OR NICOTIANA AS A MODEL EXPERIMENTAL SYSTEM, MAINLY BECAUSE THESE PLANTS RESPOND WELL FOR REGENERATION IN CELL CULTURE. THERE IS AN OBVIOUS NEED TO EXTEND THESE STUDIES TO OTHER SPECIES, FOREST TREES IN PARTICULAR, ...

THE OBJECTIVE IS TO DEVELOP A TOOL FOR DESIGNING VORTEX FLAPS ON ADVANCED FIGHTER AIRCRAFT INCLUDING THE EFFECTS OF VISCOSITY. ANALYTICAL METHODS, INC. PROPOSES TO USE AN UNSTEADY TIME-STEPPING VERSION OF ITS SURFACE SINGULARITY PANEL METHOD, VSAERO, AS A BASIS FOR THIS WORK. THIS WILL GENERATE THE PRELIMINARY VORTEX STRUCTURE (LEADING-EDGE VORTICE, FOREBODY VORTICES, ETC.) FOR THE COMPLETE CONFIG ...

THE FLOW FIELD ABOUT POWERED LIFT VEHICLES CAN BECOME VERY COMPLEX DUE TO HIGH ANGLES OF ATTACK AND LIFTING JETS. IN ADDITION TO MODELING PROPULSION/AIRFRAME INTERACTIONS, THEREFORE, FLOW PREDICTION METHODS MUST TREAT THE PROBLEMS OF SEPARATION AND THE TRANSIENT EFFECTS OF PASSING VORTICAL STRUCTURES INTERACTING WITH THE AIRFRAME. ANALYTICAL METHODS, INC. (AMI) PROPOSES TO EXTEND ITS POWERED LIFT ...

WOOD WAFERBOARD COULD BE UTILIZED FOR SIDING AND OTHER EXTERIOR EXPOSURE APPLICATION IF IT WERE MORE DIMENSIONALLY STABLE WHEN EXPOSED TO CYCLIC HUMIDITY CONDITIONS OR ENVIRONMENTS WHERE THE PRODUCT ABSORBS MOISTURE. ASPEN WAFERBOARD MARKETS COULD BE EXPANDED IF THE THICKNESS SWELLING AND LINEAR EXPANSION UNDER WET CONDITIONS WERE EQUAL TO OR LESS THAN PLYWOOD. A FEASIBILITY STUDY WILL DETERMINE T ...

THE USE OF COMPUTER CODES THAT SIMULATE FLUID FLOWS IS BECOMING INCREASINGLY IMPORTANT IN THE DESIGN OF AIRCRAFT COMPONENTS. THE CURRENT STATE OF THE TECHNOLOGY OF NUMERICAL SIMULATION OF VISCOUS FLUID FLOWS IS SUFFICIENT FOR DEVELOPING ENGINEERING TOOLS FOR FLOW ANALYSIS OF VARIOUS TYPES OF COMPLEX THREE-DIMENSIONAL FLUID FLOWS. OF PARTICULAR INTEREST ARE FLOWS WITH AERODYNAMIC BODIES PERIODICALL ...

THE LONG-TERM GOSL OF THIS RESEARCH IS TO CONSTRUCT AND EVALUATE A NONINVASIVE DEVICE THAT WILL ASSESS THE FUNCTIONAL INTEGRITY OF HYPOTHERMIC PERFUSED KIDNEYS PRIOR TO TRANSPLANT. THE DEVICE IS BASED ON MEASUREMENTS OF CHANGES IN MITOCHONDRIAL ELECTRON-TRANSPORT PROTEIN-OXIDATION STATES IN THE KIDNEY CORTEX. THESE CHANGES CAN BE MEASURED SPECTROPHOTOMETRICALLY AND WILL BE IMAGED AT THE SURFACE OF ...

CONVENTIONAL ROCK CORE DRILLING AT GREAT DEPTHS IS EXTREMELY EXPENSIVE AND TIME CONSUMING. ITS MAJOR DRAWBACK IS THE REQUIRED LENGTH OF DRILL PIPE. THE SUSPENSION CORE DRILL IS SUPPORTED BY CONTINUOUS FLEXIBLE LEADS HELD ON ONE OR MORE HIGH-SPEED REELS. WITHDRAWALS AND REPLACEMENT TIMES CAN BE REDUCED BY AN ORDER-OF-MAGNITUDE. COMMERCIAL USES INCLUDE STANDARD CORING APPLICATIONS AS WELL AS INTERMI ...
