Hydrochemistry, mineralogy and sulphur isotope geochemistry of acid mine drainage at the Mt Morgan mine environment, Queensland, Australia

Mineralogical, hydrochemical and S isotope data were used to constrain hydrogeochemical processes that produce acid mine drainage from sulfidic waste at the historic Mount Morgan Au–Cu mine, and the factors controlling the concentration of SO4 and environmentally hazardous metals in the nearby Dee River in Queensland, Australia. Some highly contaminated acid waters, with metal contents up to hundreds of orders of magnitude greater than the Australia–New Zealand environmental standards, by-pass the water management system at the site and drain into the adjacent Dee River. Mine drainage precipitates at Mt. Morgan were classified into 4 major groups and were identified as hydrous sulfates and hydroxides of Fe and Al with various contents of other metals. These minerals contain adsorbed or mineralogically bound metals that are released into the water system after rainfall events. Sulfate in open pit water and collection sumps generally has a narrow range of S isotope compositions (δ34S = 1.8–3.7‰) that is comparable to the orebody sulfides and makes S isotopes useful for tracing SO4 back to its source. The higher δ34S values for No. 2 Mill Diesel sump may be attributed to a difference in the source. Dissolved SO4 in the river above the mine influence and 20 km downstream show distinctive heavier isotope compositions (δ34S = 5.4–6.8‰). The Dee River downstream of the mine is enriched in 34S (δ34S = 2.8–5.4‰) compared with mine drainage possibly as a result of bacterial SO4 reduction in the weir pools, and in the water bodies within the river channel. The SO4 and metals attenuate downstream by a combination of dilution with the receiving waters, SO4 reduction, and the precipitation of Fe and Al sulfates and hydroxides. It is suggested here that in subtropical Queensland, with distinct wet and dry seasons, temporary reducing environments in the river play an important role in S isotope systematics

Entanglement between a qubit and the environment in the spin-boson model

The quantitative description of the quantum entanglement between a qubit and its environment is considered. Specifically, for the ground state of the spin-boson model, the entropy of entanglement of the spin is calculated as a function of α, the strength of the ohmic coupling to the environment, and ɛ, the level asymmetry. This is done by a numerical renormalization group treatment of the related anisotropic Kondo model. For ɛ=0, the entanglement increases monotonically with α, until it becomes maximal for α→1-. For fixed ɛ>0, the entanglement is a maximum as a function of α for a value, α=αM

(FAB05_058) The cathedral precinct: ideal and contingency

Henry-Russell Hitchcock, in his review of High Victorian Gothic architecture in Australia, writes that the Anglican Cathedral in Brisbane is perhaps the finest. John Loughborough and Frank Loughborough Pearson's designs for Brisbane embody the full ideal of the nineteenth-century English cathedral. While the ideal represented in the cathedral church itself might be readily appreciated, the more encompassing ideal for housing an entire Anglican cathedral establishment may be less well known and less apparent on the site. Although it is only partly built, St John's is probably the only Anglican cathedral in Australia with a comprehensive nineteenth-century precinct plan.

A Future for the Past: Rethinking the Garden Suburb

In the quest for sustainability in affluent urban societies we could do much worse than to look again at what the garden suburb attempted to do. Brentham garden suburb in West London, which has recently celebrated its centenary, is a case in point.

'Living together on one's own': Cohousing for older people - an example from Denmark and The Netherlands

‘Living together on one’s own’ is the seemingly contradictory expression of the National Association of Housing Communities for Elderly People (LVGO) in The Netherlands which in fact captures the essence of cohousing. Cohousing is a novel kind of neighbourhood, housing a novel form of intentional community, which began to take shape in Denmark in the early to mid-1960s and, independently, in The Netherlands a few years later. The inventors of cohousing wanted to live in a much more communal or community-oriented neighbourhood than was usual, but they wanted to do so without sacrificing the privacy of individual families or households and their dwellings. Could they have their cake and eat it too? It would seem so. What is cohousing for older people (op-cohousing)? Op-cohousing is essentially no different, except for the differences in outlook or expectations, experience, interests and abilities that a particular, exclusively older, group of people have brought to this housing type. I discuss and analyse several communities in both countries.
