    The prestige of sustainable living: implications for water use in Australia

    No full text
    The paper outlines water conservation behaviours and assesses the level of congruity between the stated water use of householders against their actual metered consumption. A profile of high water users in three parts of South Australia is offered: two metropolitan areas differing in socio-economic characteristics and a regional town. The research used a postal questionnaire, a follow-up telephone interview and corresponding household water meter readings. Location, household size and annual household income have significant predictive qualities for high per capita water use. The number of times gardens were watered in a week, watering the garden more often than was permitted under the restrictions, and the manner in which conservation behaviours were carried out helped predict high per capita water use. Participants had an accurate idea of the magnitude of their water use and how it compared with that of other households. High water users knew that they were high consumers of water. Implications of the findings for water demand management are briefly outlined

    Grain boundary character distributions in Ni-16Cr-9Fe using selected area channeling patterns: Methodology and results

    Selected area channeling patterns imaged on an SEM are digitized and displayed on the screen of a Macintosh computer, on which the user selects channeling bands that are measured to determine orientation. Grain boundary misorientations are found using the orientation information for pairs of grains adjacent at grain boundaries, and the boundaries are classified as low angle boundaries (LABs), coincident site lattice boundaries (CSLBs), or general boundaries (GHABs) based on the misorientation information. The technique was implemented to analyze the grain boundary character distributions (GBCDs) in Ni-16Cr-9Fe. The GBCDs of solution annealed material were similar to those expected in an aggregate of randomly oriented polycrystals. However, sequential thermomechanical treatments (5% tensile strain + 945°C:75 min + 2% tensile strain + 890°C:15 h + 3% tensile strain + 890°C:20 h or 9% compressive strain + 890°C:20 h + 9% compressive strain + 890°C:20 h + 3% compressive strain + 890°C:15 h) applied after the solution anneal lowered the proportions of GHABs in the GBCDs from 76–79% to 47–64%. The CSL-enhanced GBCDs of both the tensile-deformed samples and the compression-deformed sample appear to have evolved mainly through impingement of twin and twin-related boundaries during recrystallization; the CSL-enhanced GBCD of a compression-deformed sample appears to have been influenced by grain rotation processes to a greater degree than were the tensile-deformed samples. The CSL boundaries in the CSL-enhanced GBCDs were, in general, closer to the exact CSL misorientations than were those in the near-random GBCDs of the solution annealed material. An analysis of the distribution of misorientation axes did not indicate any correlation between grain misorientation texture and GBCD evolution.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50390/1/1060190309_ftp.pd
