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's upcoming missions to the Moon and beyond. More than just remote sensors, they will be expected to manipulate their environment in a complex and useful way - carrying objects, using tools, and assisting the crew with various physical activities. NASA has been developing world-class dexterous end effectors for years. Unfortunately, developing softwa ...

NASA is currently pursuing an advanced space suit portable life support system (PLSS) for future missions that could reach the moon or Mars. The Liquid Cooling and Ventilation Garment (LCVG) is a critical component of the PLSS and improvements are needed to reduce weight and improve comfort and mobility. NASA research has shown that the LCVG tubing is a significant heat transfer bottleneck because ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

A new class of solid-state, high-performance cryogenic coolers is proposed for space-based applications. Traditionally, cryocoolers for such applications have been Stirling or pulse tube refrigerators. These cryocoolers, although effective, are heavy, bulky, inefficient, and may cause vibrations. A high-performance solid-state cryocooler based on thermomagnetic cooling via the Ettingshausen effect ...

THIS RESEARCH ATTEMPTS TO ADVANCE THE STATE-OF-THE-ART OF BALLOON DESIGN BY DEVELOPING A METHOD TO REALISTICALLY APPROXIMATE THE STRESS LEVELS IN AN ASCENDING BALLOON. THE APPROACH WILL BE TO COMBINE EXISTING STUDIES ON ASCENT SHAPES, MATERIAL PROPERTIES, AND HEAT TRANSFER MECHANISMS TO PRODUCE A FIRST ORDER ESTIMATE OF STRESSES IN THE WALL OF A BALLOON WITH EITHER INTERNAL OR EXTERNAL CAPS. THE F ...

Based on lessons learned from previously-funded SBIR work for DARPA on in-space robotic reconfiguration and utilization of existing flight-rated structures, Made In Space, Inc. (MIS) proposes the Apeiron Space Integration System to meet NASA requirements for a modular assembly and integration architecture that enables the routine expansion, upgrade, and refurbishment of persistent robotic platform ...

NASA IS CONTINUALLY DEVELOPING NEW SYSTEMS RANGING FROM COMPUTER SOFTWARE TO TEST FACILITIES TO LARGE SPACECRAFT. EACH SYSTEM DEVELOPMENT IS INITIATED AND CONTROLLED THROUGH THE USE OF REQUIREMENTS SPECIFICATIONS. THE PROPOSED STUDY WILL DETERMINE THE FEASIBILITY OF DEVELOPING AN AUTOMATED TECHNICAL DOCUMENTATION SYSTEM FOR A DESK TOP COMPUTER. THE SYSTEM WILL BE PROTOTYPED TO DEVELOP AND TEST CON ...

Vector vortex waveplates (VVWs) have been shown to be useful for coronagraphy and other applications requiring proximity glare suppression. BEAM Co. has been on the forefront of development of VVWs for such applications, and is well-positioned to apply past experience to extending this technology into new regions of the spectrum, including the ultraviolet, and to make it possible to achieve high ...
