Lunar hand tools

Tools useful for operations and maintenance tasks on the lunar surface were determined and designed. Primary constraints are the lunar environment, the astronaut's space suit and the strength limits of the astronaut on the moon. A multipurpose rotary motion tool and a collapsible tool carrier were designed. For the rotary tool, a brushless motor and controls were specified, a material for the housing was chosen, bearings and lubrication were recommended and a planetary reduction gear attachment was designed. The tool carrier was designed primarily for ease of access to the tools and fasteners. A material was selected and structural analysis was performed on the carrier. Recommendations were made about the limitations of human performance and about possible attachments to the torque driver

Quantifying the social costs of pharmaceutical opioid misuse and illicit opioid use to Australia in 2015/16

In recent decades the range and patterns of opioids used for extra-medical purposes have changed. The use of pharmaceutical opioids exceeds the use of heroin. In 2017, 63 percent of opioid deaths were attributed exclusively to pharmaceutical opioids, 28 percent to illicit opioids and 8 percent to both illicit and pharmaceutical opioids (aged 15-64 years). The objective of this report was to estimate the social costs arising from extra-medical opioid use in Australia for the financial year 2015/16. Due to data limitations in most cases we only estimated the costs occurring in this 12 month period. For example, on-going care of chronic conditions was not included. The exceptions to this were for certain harms which occurred in 2015/16 but which had longer-term ramifications, for example premature deaths, where discounted streams of future costs (lost economic activity and lost contributions to household chores) and partially offsetting savings (future health expenditure ’avoided’ by premature deaths) were estimated. The authors also included the long-term costs of road traffic accidents, as were the expected future costs of opioid attributable imprisonment for those sentenced in 2015/16

Line Emission Mapper (LEM): Probing the physics of cosmic ecosystems

The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe's structure formation. It will also provide transformative new observing capabilities for every area of astrophysics, and to heliophysics and planetary physics as well. LEM's main goal is a comprehensive look at the physics of galaxy formation, including stellar and black-hole feedback and flows of baryonic matter into and out of galaxies. These processes are best studied in X-rays, and emission-line mapping is the pressing need in this area. LEM will use a large microcalorimeter array/IFU, covering a 30x30' field with 10" angular resolution, to map the soft X-ray line emission from objects that constitute galactic ecosystems. These include supernova remnants, star-forming regions, superbubbles, galactic outflows (such as the Fermi/eROSITA bubbles in the Milky Way and their analogs in other galaxies), the Circumgalactic Medium in the Milky Way and other galaxies, and the Intergalactic Medium at the outskirts and beyond the confines of galaxies and clusters. LEM's 1-2 eV spectral resolution in the 0.2-2 keV band will make it possible to disentangle the faintest emission lines in those objects from the bright Milky Way foreground, providing groundbreaking measurements of the physics of these plasmas, from temperatures, densities, chemical composition to gas dynamics. While LEM's main focus is on galaxy formation, it will provide transformative capability for all classes of astrophysical objects, from the Earth's magnetosphere, planets and comets to the interstellar medium and X-ray binaries in nearby galaxies, AGN, and cooling gas in galaxy clusters. In addition to pointed observations, LEM will perform a shallow all-sky survey that will dramatically expand the discovery space
