Testing of flat conductor cable to Underwriters Laboratory standards UL719 and UL83

The flat conductor cable (FCC) which was tested consisted of three AWG No. 12 flat copper conductors laminated between two films of polyethylene terephthalate (Mylar) insulation with a self-extinguishing polyester adhesive. Results of the tests conducted on this cable, according to specifications, warrants the use of this FCC for electrical interconnections in a surface nonmetallic protective covering

Solar System Processes Underlying Planetary Formation, Geodynamics, and the Georeactor

Only three processes, operant during the formation of the Solar System, are responsible for the diversity of matter in the Solar System and are directly responsible for planetary internal-structures, including planetocentric nuclear fission reactors, and for dynamical processes, including and especially, geodynamics. These processes are: (i) Low-pressure, low-temperature condensation from solar matter in the remote reaches of the Solar System or in the interstellar medium; (ii) High-pressure, high-temperature condensation from solar matter associated with planetary-formation by raining out from the interiors of giant-gaseous protoplanets, and; (iii) Stripping of the primordial volatile components from the inner portion of the Solar System by super-intense solar wind associated with T-Tauri phase mass-ejections, presumably during the thermonuclear ignition of the Sun. As described herein, these processes lead logically, in a causally related manner, to a coherent vision of planetary formation with profound implications including, but not limited to, (a) Earth formation as a giant gaseous Jupiter-like planet with vast amounts of stored energy of protoplanetary compression in its rock-plus-alloy kernel; (b) Removal of approximately 300 Earth-masses of primordial gases from the Earth, which began Earth's decompression process, making available the stored energy of protoplanetary compression for driving geodynamic processes, which I have described by the new whole-Earth decompression dynamics and which is responsible for emplacing heat at the mantle-crust-interface at the base of the crust through the process I have described, called mantle decompression thermal-tsunami; and, (c)Uranium accumulations at the planetary centers capable of self-sustained nuclear fission chain reactions.Comment: Invited paper for the Special Issue of Earth, Moon and Planets entitled Neutrino Geophysics Added final corrections for publicatio

Robotic control of the seven-degree-of-freedom NASA laboratory telerobotic manipulator

A computationally efficient robotic control scheme for the NASA Laboratory Telerobotic Manipulator (LTM) is presented. This scheme utilizes the redundancy of the seven-degree-of-freedom LTM to avoid joint limits and singularities. An analysis to determine singular configurations is presented. Performance criteria are determined based on the joint limits and singularity analysis. The control scheme is developed in the framework of resolved rate control using the gradient projection method, and it does not require the generalized inverse of the Jacobian. An efficient formulation for determining the joint velocities of the LTM is obtained. This control scheme is well suited for real-time implementation, which is essential if the end-effector trajectory is continuously modified based on sensory feedback. Implementation of this scheme on a Motorola 68020 VME bus-based controller of the LTM is in progress. Simulation results demonstrating the redundancy utilization in the robotic mode are presented

HEALTHY BITES: A CHALLENGE-BASED WORKSITE WELLNESS NUTRITION PROGRAM

Purpose: The worksite health promotion literature has shown that successful nutrition communication programs call for making small changes to diet, one at a time. The use of observational learning (role models) and a “challenge” scenario for behavior change is supported by Social Cognitive Theory. The significance of these small changes in worksites is underscored by a recent Harvard Business Review article suggesting workplace wellness programs can return up $2.71 on every$1.00 invested. The purpose of the proposed program, Healthy Bites, is to increase knowledge of employees regarding the impact of specific nutrition behaviors related to reducing cancer risk and improving weight status. The relationships between types of activities attended and/or tools used with degree of behavior change will also be evaluated. Methods: Eligible participants are MD Anderson Cancer Center employees. Participants will be asked to complete monthly nutrition challenges during 2013 to possibly reduce cancer risk and improve weight status. Challenge topics include: eating breakfast, not skipping meals, consuming whole grains, following the MyPlate diagram, eating less red meat and processed meat, eating more plant-based protein, drinking more water, eating out less, increasing fruit and vegetables, limiting sodium, and drinking less alcohol. Each month participants will receive printed tools, tips and recipes via email. Participants will also be able to attend cooking demonstrations and informational lectures, as well as read stories about fellow employees who have successfully completed the challenges. Results: (Evaluation): Surveys will be distributed to participants at program initiation (January 2013), the mid-point (July 2013) and at conclusion (December 2013). The surveys will evaluate/assess: nutrition knowledge, nutrition habits, enhancements to improve the challenges, likeability of program, number of challenges completed, whether families participating together were more successful, and usefulness of Healthy Bites tools and content. Conclusions: Healthy Bites will evaluate how a nutrition behavior change program can be successfully implemented in a large hospital-based workplace setting to improve nutrition knowledge and habits among employees

Advances in Low-Cost Manufacturing and Folding of Solar Sail Membranes

Solar sail membranes must have a high area-to-mass ratio and high solid volume fraction when stowed. In order to meet mission requirements, current solar sail projects, such as NASAs Near Earth Asteroid Scout, require metallized sail membranes with thicknesses on the order of 2-3 m. These very thin membranes do not retain creases like thicker membranes, solar panels, or paper models. For Cubesat-class spacecraft, volume, rather than mass, is often the driving requirement for deployable structural elements. These two factors make it both difficult and highly desirable to characterize the practical differences between solar sail membrane packaging methods with laboratory demonstrations. This paper presents lessons gathered from lab work with solar sail membranes at a 10-meter scale
