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, ...

INFORMATION USE HAS BEEN IDENTIFIED AS A KEY FACTOR IN ENHANCING COMPETITIVENESS OF THE NATION'S INDUSTRIES. THE RESEARCH PROPOSED WOULD RIGOROUSLY EVALUATE CURRENT IMPEDIMENTS TO EFFECTIVE USE, DEFINE POTENTIAL ECONOMIC VALUE OF ENHANCED USE, AND EXPLORE THE OPPORTUNITY FOR COMPUTERIZED DECISION AIDS TO INCREASE INFORMATION EFFECTIVENESS IN DECISIONMAKING. THESE GOALS WOULD BE INVESTIGATED FOR TH ...

SUPERCONDUCTING HEAVY-ION BOOSTERS ARE LIMITED IN THEIR MASS RANGE BY THE VELOCITY ACCEPTANCE OF THE RESONATORS IN THEIR FIRST SECTIONS. A NEED HAS ARISEN TO DO NUCLEAR PHYSICS IN MASS RANGES INACCESSIBLE WITH EXISTING ACCELERATING STRUCTURES. THE END PRODUCT THAT WOULD RESULT FROM THIS RESEARCH IS AN ACCELERATING RESONATOR WITH AN UPPER MASS ACCEPTANCE 50% LARGER THAN EXISTING STRUCTURES. OUR EXP ...

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 ...

THE RESEARCH EFFORT IS DIRECTED TOWARDS DETERMING THE TECHNICAL FEASIBILITY OF MORPHOLOGICALLY INVARIENT ELECTRODE/SOLID POLYMER ELECTROLYTE (SPE) JUNCTIONS FOR LONGCYCLE LIFE ELECTROCHEMICAL CELLS. ALKALI ION CONDUCTING SPES TO BE USED IN THIS PROGRAM WILL INCLUDE THOSE BASED UPON POLY(ETHYLENE OXIDE) AND THE POLYPHOSPHAZENES. NOVEL SECONDARY ELECTRODES WILL INCLUDE THE LITHIUM INTERCALATING MATE ...

TECHNICAL EFFORT IS DIRECTED TOWARDS DETERMING THE FEASIBILITY OF AN ELECTROCHEMICALLY REVERSIBLE LIQUID NEGATIVE ACTIVE MATERIAL CONSISTING OF LITHIUM DISSOLVED IN LIQUID AMMONIA TO GIVE A NOVEL SOLVATED ELECTRON SECONDARY LITHIUM ELECTRODE. CONTAINMENT OF THE ACTIVE MATERIAL FROM DIRECT CONTACT TO THE LIQUID NON-AQUEOUS ELECTROLYTE IS REALIZED VIA USE OF A LITHIUM INTERCALATED ELECTRONICALLY CON ...

COMMERCIAL TISSUE CULTURE PROPAGATION OF PLANT CULTIVARS IS NOW LIMITED TO SPECIALTY CROPS BECAUSE OF THE HIGH UNIT COSTOF PLANTS SO PROPAGATED. THIS COST IS THE COMBINED EFFECT OF THE LABOR INTENSIVE NATURE OF MANUAL TISSUE TRANSFER WHETHER FOR MEDIUM RENEWAL OR CHANGE AND LOW MULTIPLICATION RATE OF THE CULTURE METHOD USED. THE ROOTING MEDIUM MODULE NOW WIDELY USED AS A FINAL MEDIUM FOR ROOTING O ...
