Method for producing oxygen from lunar materials

This invention is related to producing oxygen from lunar or Martian materials, particularly from lunar ilmenite in situ. The process includes producing a slurry of the minerals and hot sulfuric acid, the acid and minerals reacting to form sulfates of the metal. Water is added to the slurry to dissolve the minerals into an aqueous solution, the first aqueous solution is separated from unreacted minerals from the slurry, and the aqueous solution is electrolyzed to produce the metal and oxygen

Biological control of conifer seed damage by the deer mouse (Peromyscus maniculatus)

This paper describes the development of a biological technique that successfully controls conifer seed damage by the deer mouse. Eleven experiments have been conducted on three study areas at the University of British Columbia Research Forest, Maple Ridge, B.C. Populations of deer mice have been monitored in all experiments with data from 56,000 trap nights. The technique involves a mixture of conifer seed (Douglas fir) with sunflower seed and oats which is uniformly distributed on logged areas in the late winter-early spring. Survival of conifer seed with these alternate foods was excellent, compared with control Douglas fir by itself, for an 8-week period during this time of year. Populations of seed-eating birds and chipmunks are not present on clearcut areas from late October to early April. In addition, deer mice are at their lowest density during the spring. Thus, the use of alternate foods with Douglas fir seed in a direct-seeding operation at the appropriate time of year will result in successful regeneration of cutover forest lands

Growth and claw regeneration of the stone crab, Menippe mercenaria

Savage, T. and J.R. Sullivan. 1978. Growth and Claw Regeneration of the Stone Crab, Menippe mercenaria. Fla. Mar. Res. Publ. No. 32.23 pp. Laboratory-maintained and feral crabs were observed for incremental carapace width and major and minor claw growth. Morphometric relationships for male and female carapace width against length and carapace width against major and minor claw sizes were derived. Only slopes of carapace width us. female major and male minor claws were not significantly different at the 95% confidence level. Feral normal male incremental growth exceeded that of normal females for all parameters. Normal laboratory females possessed greater average carapace width growth but less claw growth than did their male counterparts. All laboratory growth was more uniform but incrementally smaller than corresponding field growth. A hypothetical growth plot constructed from incremental growth of several crabs indicated ages at attainment of sexual maturity and legal size to be 10 and 30 months. A pictorial description of stone crab claw regeneration is presented. Minor claws realized greater regeneration after one and two molts (73.5% and 96.5% of pre-autotomized sizes) than did major claws (68.6% and 89.0%). Intermolt interval of laboratory crabs increased with larger carapace width sizes. Claw loss shortened or lengthened duration of the intermolt period depending upon whether the claw was removed shortly after a molt or later in the cycle. (Document has 27 pages.

From Bad to Worse: Senior Economic Insecurity on the Rise

Dancing with loneliness in later life: A pilot study mapping seasonal variations

Temporal variations in loneliness at the individual and population level have long been reported in longitudinal studies. Although the evidence is limited due to methodological distinctions among studies, we broadly know that loneliness as one ages is a dynamic experience with people becoming more or less lonely or staying the same over time. There is, however, less evidence to understand individual variations in loneliness over shorter periods of time. This paper reports on one element of a small mixed method pilot study to investigate seasonal variations in loneliness over the course of one year and to test the effectiveness of tools used to collect data at repeated short intervals. Our findings confirm that loneliness is dynamic even over shorter periods of time with participants reporting to be lonelier in the evenings, weekends and spring-summer period. Data measures were at times problematic due to language and/or interpretation and reinforce the relevance of reviewing the more common approaches to studying loneliness to more effectively capture the complex and individual nature of the experience.Brunel University Londo

Hard Choices: Navigating the Economic Shock of Unemployment

During the Great Recession of 2007 to 2009, millions of Americans faced severe economic hardship, forcing difficult decisions about how to stabilize their families' financial well-being and prevent downward economic mobility. Americans with savings were forced to weigh immediate needs against long-term investments, choosing whether to deplete personal assets in order to stay afloat. Those without wealth to fall back on were in an even more precarious position, leading them to turn to family assistance, debt, and other public and private supports when available.This study examines how families weather economic shocks through a close focus on one particular event -- the experience of unemployment, with specific attention to differences by race and family income. The analysis used a nationally representative sample of working-age families from the Panel Study of Income Dynamics or PSID, following the same households from 1999 to 2009. To provide greater insight into the challenges and choices families faced, the report also drew on a unique longitudinal data set of in-depth interviews with 51 families that endured one month or more of unemployment between 1998 and 2012

Thermodynamics-Based Discovery of New K-La-Zr-O Compounds via Hydrothermal Synthetic Methods

This project investigates aqueous modeling coupled with mild hydrothermal methods (200 °C, 16 atm) for discovery of new compounds, goals for advanced materials development outlined in SC Vision 2025 and NSF Big Ideas. Innovative luminescent materials, such as scintillators, are needed for opto-electronics and other optical technologies. Hydrothermal methods were performed, with thermodynamic guidance from aqueous speciation calculations in OLI Studio, to look for compounds in the K-La-Zr-O quaternary system. This system choice was inspired by several Na-Y-Si-O compounds previously synthesized by supercritical hydrothermal methods. By altering compositions of reactants, it is possible to generate trace amounts of novel crystals of new stoichiometries. In the previous discovery of Zn2EDTA·2H2O, optimum hydrothermal conditions were just outside of the thermodynamic stability region for ZnO, suggesting that the edges of such stability regions are potential places for discovery work. With OLI Studio, yield diagrams were constructed for the K-La-Zr-O system, with water-soluble metal salts, chelating agent, and base as reactants. Chemical systems readily form thermodynamically stable binary/ternary compounds: in this case, zirconia (ZrO2) and lanthanum hydroxide (La(OH)3). Within Zr and La subsystem yield diagrams, where the concentration ratio of metals is plotted against base concentration, locations just outside of the ZrO2 stability region were targeted for Zr:La ratios of 1:1 and 4:1. Scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS) revealed polycrystalline morphology with some single crystals (≈50 microns) of hexagonal and greater (6+ sides) geometry containing significant amounts of oxygen, lanthanum, and zirconium, suggesting formation of a lanthanum zirconate compound
