THE BIOCHEMICAL AND SYNTHETIC CAPACITY OF HIGHER PLANTS, AS SHOWN BY THEIR NATURAL CONTENT OF SUBSTANCES, HAS BEEN USED FOR CENTURIES IN SUPPLYING MATERIALS IMPORTANT IN PHARMACOLOGY AND IN FLAVORS AND FRAGRANCES. MANY OF THESE SECONDARY PRODUCTS ARE IN SHORT SUPPLY AND AN ENORMOUS EFFORT HAS TO BE EXTENDED TO GET THEM. ATTEMPTS TO USE CELL CULTURES OF HIGHER PLANTS AS A MEANS OF PRODUCING SECONDA ...

Robots will play an important role in NASA#39;s upcoming missions to the Moon and beyond.nbsp; They will need to manipulate their environment in complex and useful ways - carrying objects, using tools, and assisting crew.nbsp; NASArsquo;s humanoid robots have highly dexterous end-effectors, but developing software to fully utilize such hands remains a challenging task.nbsp; Grasping strategies are ...

SUPER ACCURATE ADAPTIVE COMPUTATIONAL SCHEMES FOR THE ANALYSIS OF FLUID STRUCTURE INTERACTION AND COMPLEX THREE-DIMENSIONAL INTERNAL FLOWS ARE TO BE DEVELOPED. NEW PETROV-GALERKIN FINITE ELEMENT METHODS FOR SOLVING THE NAVIER-STOKES EQUATIONS. COUPLED WITH THE EQUATIONS OF MOTION OF ELASTIC DUCTS AND MANIFOLDS, ARE TO BE DEVELOPED AND USED TO SIMULATE FLOWS IN AEROSPACE PROPULSION SYSTEMS (SUCH AS ...

THE GOAL OF PHASE I IS DEVELOPMENT OF AN ADVANCED OPTICALLY PUMPED HELIUM MAGNETOMETER CONCEPT. THIS INSTRUMENT WILL MEASURE MAGNETIC FIELDS IN THE 1 TO 10-8 GAUSS RANGE WITH ORDER OF MAGNITUDE IMPROVEMENTS IN SENSITIVITY AND ABSOLUTE ACCURACY OVER EXISTING MAGNETOMETERS. OPTICALLY PUMPED HELIUM ISOTOPES CAN BE OPTICALLY PUMPED AND USED AS MAGNETOMETERS IN THE FOLLOWING THREE MODES: (1) VECTOR MOD ...

Infrared photodetectors operating in the wavelength range of 3-20 mm and beyond are of great importance to a wide variety of ongoing and future NASA missions, as well as many commercial and military applications in infrared (IR) imaging and sensing. Hence, there is a constant pursuit of advances in detector technologies and enabling technologies related to increasing detector performance. In recen ...

This Small Business Innovative Research (SBIR) project will demonstrate the feasibility of using fiber-optic sensors on the human-scale robot hand that has been developed by the Robotic Systems Technology Branch at the NASA Johnson Space Center (JSC). The fiber-optic sensor approach will provide an innovative way to measure the forces involved with dexterous grasps and power during extra-vehicular ...

The goal of medical simulation-based training such as high-fidelity manikin simulators, part task trainers, and screen-based virtual patients, is to approximate real-life treatment experiences without risk to live patients. While the use of sensors has ma

Frequency selective surfaces (FSSs) are periodic arrays of conductive elements/patches that cause a particular reflection response when illuminated with high frequency electromagnetic energy. nbsp;These arrays arenbsp;used for high frequency filters and in antenna applications.nbsp; We propose to use FSSs as multi-functional sensors. nbsp;FSS sensors are unpowered, low-profile (thin), wireless and ...

An advanced nuclear electric propulsion system based on gaseous and liquid droplet core reactor (GCR) with magnetohydrodynamic (MHD) power conversion is proposed. The energy of the partially ionized fissioning gas in GCR is directly coupled to the applied magnetic field of the MHD generator to achieve high conversion efficiency at high temperatures. The high operating temperature of the combined G ...
