THE PRODUCTION OF HYBRIDOMAS BY CELL FUSION IS AN INCREASINGLY IMPORTANT ASPECT OF BOTH MEDICAL RESEARCH AND CLINICAL PROTOCOLS. IN PARTICULAR, IT HAS THE POTENTIAL FOR PROVIDING SENSITIVE DIAGNOSTIC REAGENTS TO RADIATION INDUCED CELL DAMAGE. WE HAVE RECENTLY CONDUCTED PRELIMINARY RESEARCH ON A NEW APPROACH, THE ELECTRONIC CELL FUSION TECHNIQUE. THIS TECHNIQUE USES AN ELECTRONIC IMPULSE TO PUNCTUR ...

AN IMPORTANT GOAL OF THE NASA MEDICAL SCIENCES PROGRAM IS TO MAINTAIN THE HEALTH OF THE ASTRONAUTS BOTH BEFORE AND DURING THE SPACE MISSIONS. TWO OF THE MOST IMPORTANT CLINICAL PARAMETERS ARE THE LEFT AND RIGHT HEART EJECTION FRACTIONS. THESE PARAMETERS, WHICH ARE SO CENTRAL TO GOOD VASCULAR PERFORMANCE ARE ALSO ONES WHICH COULD BE STRONGLY EFFECTED BY THE STRESS AND GRAVITY EFFECTS OF THE FLIGHTS ...

WE PROPOSE A PROGRAM OF RESEARCH INTO THE FUNDAMENTAL PROPERTIES OF LIINSE2, A LITTLE-KNOWN SEMICONDUCTOR OF THE I-III-VI FAMILY. THIS MATERIAL PROMISES TO BECOME A BASIS FOR A REVOLUTIONARY SOLID STATE THERMAL NEUTRON DETECTOR. DURING PHASE I, THE TERNARY EQUILIBRIUM PHASE DIAGRAM WILL BE INVESTIGATED IN THE REGION IMMEDIATELY SURROUNDING THE STOICHIOMETRIC COMPOSITION. WE WILL ALSO ELUCIDATE SOM ...

THE CONCEPT OF LIQUID FILM MEDIATED LASER PROTECTION WILL BE INVESTIGATED FOR TUNGSTEN COATED CARBON SURFACES. A COMBINED THEORETICAL-EXPERIMENTAL PROGRAM IS PROPOSED. THE THEORETICAL EFFORT WILL DETERMINE RANGES OF STABILITY FOR LIQUID FILMS UNDER CW LASER INTERACTION CONDITIONS. FILM FAILURE MECHANISMS WILL BE DEVELOPED FOR TUNGSTEN COATED CARBON AND OTHER CANDIDATE MATERIALS WILL BE IDENTIFIED. ...

THE CONCEPT OF THIN LIQUID FILM MEDIATED PROTECTION FROM LASER IRRADIATION WILL BE APPLIED TO HEAT SHIELD MATERIALS. THE CONCEPT EMPLOYS A THIN METAL FILM WHICH BECOMES LIQUID DURING IRRADIATION. THE FILM IS DESIGNED TO BE HIGHLY REFLECTING TO LASER IRRADIATION WITHOUT INTERFERING WITH THE VAPORIZATION THERMODYNAMICS OF THE HEAT SHIELD. THIS CONCEPT PROVIDES LASER HARDENING IN AN EXO ENVIRONMENT. ...

THE PROPOSED STUDY WILL INVESTIGATE THE UTILITY OF A LAYERED LASER DEFENSE SYSTEM (LLDS) DESIGNED TO ELIMINATE U.S. BOOSTERS AND/OR REENTRY VEHICLE SYSTEMS. THE PRINCIPAL OBJECTIVE IS TO IDENTIFY AND EVALUATE ACTIVE COUNTERMEASURES DESIGNED TO DEFEAT ONE OR MORE LAYERS OF THE LLDS. TASKS TO BE ACCOMPLISHED INCLUDE: (1) THREAT DEFINITION; (2) MISSILE BASELINE VULERABILITY ASSESSMENT; (3) BASELINE S ...
