Big tobacco's box fetish: Plain packaging at the High Court

Tobacco, says the World Health Organisation (WHO), is “the only legal consumer product that kills when used exactly as intended by the manufacturer.”

The High Court and the Marlboro Man: The plain packaging decision

The High Court of Australia’s ruling on the plain packaging of tobacco products is one of the great constitutional cases of our age. The ruling will resonate throughout the world - as other countries will undoubtedly seek to emulate Australia’s plain packaging regime.

The olive revolution: Australia's plain packaging leads the world

After much political debate, the Australian Parliament passed the Tobacco Plain Packaging Act 2011 (Cth). Australian legislators, such as Richard di Natale, provided moving accounts for the need for plain packaging of tobacco products.

Cigarettes will kill you: The High Court of Australia and the plain packaging of tobacco products

Tobacco, says the World Health Organization (WHO), is “the only legal consumer product that kills when used exactly as intended by the manufacturer.” With a view to discouraging smoking and giving effect to the WHO Framework Convention on Tobacco Control, the Australian Parliament passed the Tobacco Plain Packaging Act 2011 (Cth), in November of that year. The legislation was supported by all the major political parties.

Ireland, plain packaging, and the olive revolution

A world leader in public health, Australia introduced plain packaging of tobacco products. Julia Gillard – the Prime Minister of Australia at the time responsible for plain packaging – has observed: “Since 1 December 2012, cigarettes packets in Australia do not sparkle with gold or silver and do not have any other way to catch and please the eye. They’re a uniform drab colour, with most of the box taken up with the most graphic health warnings. Gruesome pictures of disease perhaps better described as real pictures of the ugly truth.”

New Zealand, plain packaging, and the Trans-Pacific Partnership

The New Zealand Parliament is considering the adoption of plain packaging of tobacco products with the introduction of the Smoke-Free Environments (Tobacco Plain Packaging) Amendment Bill 2014 (NZ). There has been strong support for the measure amongst the major parties – including the National Party; the Maori Party; the Labor Party; and the Greens. The New Zealand parliamentary debate has considered matters of public health and tobacco control; the role of intellectual property law; and the operation of international trade and investment law.

Aseptic Packaging of Tropical Fruit Purees

The object of this investigation was to develop high quality aseptically packaged mango and passionfruit puree products. Kensington mango puree (acidified to ph 3.5) and deseeded passionfruit pulp (ph 3.0) were sterilised in a scraped-surface heat exchanger, cooled to 20°C in a tubular heat-exchanger, aseptically packaged in sterile laminate bags. Six sterilising time/temperature combinations were compared - 85°C/15 secs, 85°C/60 secs, 90° C/15 secs, 90°/60 secs, 95°C/15 secs, 95°C/60 secs. Products were assessed immediately after processing, and after eight months ambient storage, for microbial, physical, chemical, and sensory quality. All treatments were microbiologically sound and showed no enzyme activity. Sensory quality was very acceptable, and there was no evidence of heat damage. Quality (especially colour and flavour) decreased during storage in all heat treatments.

Studies on vacuum pyrolysis of ammonium perchlorate and ammonium perchlorate/polystyrene propellant in the presence of transition metal oxides

Vacuum pyrolysis of ammonium perchlorate (AP) and ammonium perchlorate/polystyrene (PS) propellant has been studied by differential thermal analysis (DTA) in order to observe the effect of transition metal oxides on sublimation. Sublimation and decomposition being competitive processes, their proportions depend on the pressure of the pyrolysis chamber. The enthalpies for complete decomposition and complete sublimation are available from the literature and by using these data together with DTA area measurements, the extents of sublimation and decomposition have been calculated for AP and the propellant system. The effect of the metal ions on the extent and rate of sublimation depends on their nature. For AP the extent of sublimation increases with a decrease in particle size. For the propellants the powder sublimes more readily than the bulk material, but in the presence of metal ions the bulk material sublimes more readily than the powder. To substantiate this finding, the effect of MnO2 on AP sublimation as a function of particle size was examined, and it was observed that the extent of sublimation decreases as the particle size decreases.

Characterisation of wood properties and transverse anatomy for vacuum drying modelling of commercially important Australian hardwood species.

Characterisation and investigation of a number of key wood properties, critical for further modelling work, has been achieved. The key results were: • Morphological characterisation, in terms of fibre cell wall thickness and porosity, was completed. A clear difference in fibre porosity, size, wall thickness and orientation was evident between species. Results were consistent with published data for other species. • Viscoelastic properties of wood were shown to differ greatly between species and in the radial and tangential directions, largely due to anatomical and chemical variations. Consistent with published data, the radial direction shows higher stiffness, internal friction and glass transition temperature than the tangential directions. The loss of stiffness over the measured temperature range was greater in the tangential direction than the radial direction. Due to time dependant molecular relaxation, the storage modulus and glass transition temperature decreased with decreasing test frequency, approaching an asymptotic limit. Thus the viscoelastic properties measured at lower frequencies are more representative of static material. • Dynamic interactions between relative humidity, moisture content and shrinkage of four Australian hardwood timbers can be accurately monitored on micro-samples using a specialised experimental device developed by AgroParisTech – ENGREF. The device generated shrinkage data that varied between species but were consistent (repeatable) within a species. Collapse shrinkage was clearly evident with this method for Eucalyptus obliqua, but not with other species, consistent with industrial seasoning experience. To characterise the wood-water relations of this species, free of collapse, thinner sample sections (in the R-T plane) should be used.

Computational Modelling of the Vacuum Drying of Australian Hardwoods

Computational Modelling of the Vacuum Drying of Australian Hardwoods.

Evaluation of super-heated steam vacuum drying viability and development of a predictive drying model for four Australian hardwood species.

The results of drying trials show that vacuum drying produces material of the same or better quality than is currently being produced by conventional methods within 41 to 66 % of the drying time, depending on the species. Economic analysis indicates positive or negative results depending on the species and the size of drying operation. Definite economic benefits exist by vacuum drying over conventional drying for all operation sizes, in terms of drying quality, time and economic viability, for E. marginata and E. pilularis. The same applies for vacuum drying C. citriodora and E. obliqua in larger drying operations (kiln capacity 50 m3 or above), but not for smaller operations at this stage. Further schedule refinement has the ability to reduce drying times further and may improve the vacuum drying viability of the latter species in smaller operations.
