The application of Raman spectroscopy to the study of the copper chloride minerals nantokite, eriochalcite and claringbullite has enabled the vibrational modes for the CuCl, CuOH and CuOH2 to be determined. Nantokite is characterised by bands at 205 and 155 cm-1 attributed to the transverse and longitudinal optic vibrations. Nantokite also has an intense band at 463 cm-1, eriochalcite at 405 and 390 cm-1 and claringbullite at 511 cm-1. These bands are attributed to CuO stretching modes. Water librational bands at around 672 cm-1 for eriochalcite have been identified and hydroxyl deformation modes of claringbullite at 970, 906 and 815 cm-1 are observed. Spectra of the three minerals are so characteristically different that the minerals are readily identified by Raman spectroscopy. The minerals are often determined in copper corrosion products by X-ray diffraction. Raman spectroscopy offers a rapid, in-situ technique for the identification of these corrosion products.

The relationship between student well-being and the other vital outcomes of school is unequivocal. Improved outcomes in all aspects of student well-being are positively associated with improved outcomes in all other aspects of schooling. This educational imperative only serves to strengthen and support the moral imperative for schools and schooling to be inclusive, supportive and nurturing in order to maintain and support student well-being.

Existing trauma registries in Australia and New Zealand play an important role in monitoring the management of injured patients. Over the past decade, such monitoring has been translated into changes in clinical processes and practices. Monitoring and changes have been ad hoc, as there are currently no Australasian benchmarks for “optimal” injury management. A binational trauma registry is urgently needed to benchmark injury management to improve outcomes for injured patients.

Chlamydia trachomatis infections have been implicated in problems such as pelvic inflammatory disease and infertility in females. Although there are some studies examining the kinetics of ascending infection, there is limited information on the kinetics of pathology development and cellular infiltrate into the reproductive tissues in relation to the effects of inoculating dose, and a better understanding of these is needed. The murine model of female genital tract Chlamydia muridarum infection is frequently used as a model of human C. trachomatis reproductive tract infection. To investigate the kinetics of ascending genital infection and associated pathology development, female BALB/c mice were intravaginally infected with C. muridarum at doses ranging from 5102 to 2.6106 inclusion forming units. We found that the inoculating dose affects the course of infection and the ascension of bacteria, with the highest dose ascending rapidly to the oviducts. By comparison, the lowest dose resulted in the greatest bacterial load in the lower reproductive tract. Interestingly, we found that the dose did not significantly affect inflammatory cell infiltrate in the various regions. Overall, this data show the effects of infectious dose on the kinetics of ascending chlamydial infection and associated inflammatory infiltration in BALB/c mice.

What are the ethical and political implications when the very foundations of life —things of awe and spiritual significance — are translated into products accessible to few people? This book critically analyses this historic recontextualisation. Through mediation — when meaning moves ‘from one text to another, from one discourse to another’ — biotechnology is transformed into analysable data and into public discourses. The unique book links biotechnology with media and citizenship. As with any ‘commodity’, biological products have been commodified. Because enormous speculative investment rests on this, risk will be understated and benefit will be overstated. Benefits will be unfairly distributed. Already, the bioprospecting of Southern megadiverse nations, legally sanctioned by U.S. property rights conventions, has led to wealth and health benefits in the North. Crucial to this development are biotechnological discourses that shift meanings from a “language of life” into technocratic discourses, infused with neo-liberal economic assumptions that promise progress and benefits for all. Crucial in this is the mass media’s representation of biotechnology for an audience with poor scientific literacy. Yet, even apparently benign biotechnology spawned by the Human Genome Project such as prenatal screening has eugenic possibilities, and genetic codes for illness are eagerly sought by insurance companies seeking to exclude certain people. These issues raise important questions about a citizenship that is founded on moral responsibility for the wellbeing of society now and into the future. After all, biotechnology is very much concerned with the essence of life itself. This book provides a space for alternative and dissident voices beyond the hype that surrounds biotechnology.
