Hydrogen Economy Options for Australia

B. Mclellan
Global concerns over the effects of current carbon dioxide (CO2) emissions have lead to extensive research on the use of hydrogen as a potential energy carrier for a lower emissions society. Hydrogen can be produced from both fossil and renewable energy sources. The hydrogen economy, in which hydrogen will be a carrier of energy from renewable sources, is a long-term development and any increasing demand for hydrogen will probably be covered initially from fossil sources. Technologies for hydrogen generation from renewable energies are being explored, whereas technologies for hydrogen production from fossil fuels have to a certain extent reached maturity. This paper addresses the major hydrogen generation processes and utilisation technology (fuel cells) currently available for the move from a fossil fuelsbased economy to a hydrogen economy. In particular, it illustrates the applicability of different hydrogen sources using Australia as an example. [source]

National pandemic influenza preparedness planning

Eduardo Azziz-Baumgartner
Abstract, The recent outbreaks of influenza A/H5N1 and ,swine influenza' A/H1N1 have caused global concern over the potential for a new influenza pandemic. Although it is impossible to predict when the next pandemic will occur, appropriate planning is still needed to maximize efficient use of resources and to minimize loss of life and productivity. Many tools now exist to assist countries in evaluating their plans but there is little to aid in writing of the plans. This study discusses the process of drafting a pandemic influenza preparedness plan for developing countries that conforms to the International Health Regulations of 2005 and recommendations of the World Health Organization. Stakeholders from many sectors should be involved in drafting a comprehensive pandemic influenza plan that addresses all levels of preparedness. [source]

Perceptions of older people on disaster response and preparedness

Duggan S., Deeny P., Spelman R. & Vitale C.T. (2010) Perceptions of older people on disaster response and preparedness. International Journal of Older People Nursing5, 71,76 doi: 10.1111/j.1748-3743.2009.00203.x Most disasters occur in developing countries but in the last decade due to the increasing threat of floods, air disasters and terrorist threat, disaster response and preparedness is a growing global concern. Due to an ageing population across the world, older people now constitute a significant proportion of those at risk from disasters. This paper reports on a qualitative study carried out in Sri Lanka and in the United States where a group of older people were asked about aspects of disaster response and preparedness. The group from Sri Lanka (n = 9) who had direct experience of the 2004 Indian Ocean Tsunami were asked how they perceived international aid relief and a group of white Caucasians from East Coast USA (n = 8) were asked about disaster preparedness. Findings indicate that both groups had similar issues albeit that they were looking at different phases of the disaster cycle and from different cultural perspectives. Both groups identified issues related to, protecting the rights of the older person and preventing loss of independence in responding and preparing for a disaster, mistrust of government and access to resources and all expressed strong feelings of self-responsibility.

Bipolaris sorokiniana, a cereal pathogen of global concern: cytological and molecular approaches towards better control,

Jagdish Kumar
Summary Bipolaris sorokiniana (teleomorph Cochliobolus sativus ) is the causal agent of common root rot, leaf spot disease, seedling blight, head blight, and black point of wheat and barley. The fungus is one of the most serious foliar disease constraints for both crops in warmer growing areas and causes significant yield losses. High temperature and high relative humidity favour the outbreak of the disease, in particular in South Asia's intensive ,irrigated wheat,rice' production systems. In this article, we review the taxonomy and worldwide distribution, as well as strategies to counteract the disease as an emerging threat to cereal production systems. We also review the current understanding of the cytological and molecular aspects of the interaction of the fungus with its cereal hosts, which makes B. sorokiniana a model organism for studying plant defence responses to hemibiotrophic pathogens. The contrasting roles of cell death and H 2O2 generation in plant defence during biotrophic and necrotrophic fungal growth phases are discussed. [source]

Head and neck cancer in India , review of practices for prevention policy

ORAL DISEASES, Issue 7 2009
A Mishra
India, with a population of over a billion is likely to increase global concern on cancer, particularly that of head and neck. The increasing immigration of Indians is likely to influence other parts of the world and an analysis of cancer-related practices could serve as a model for defining cancer-prevention strategies across the globe. The objective of this study was to review the anti- and pro-carcinogenic practices in India pertaining to head and neck cancer. The published literature on practices, compounds/chemicals/crude reparations related to the head and neck cancer in India was retrieved for analysis, while unauthentic or local information was discarded. The anti-carcinogenic practices prevalent in India consisted of classically varied diet being predominantly vegetarian, along with spices, condiments, beverages etc. The pro-carcinogenic practices predominantly include all shades of alcoholism and tobacco intake. Moreover, the diverse culture of the country reflects unique regional practices. The enormous diversity in practices related to head and neck cancer in India is very unique and interesting. Cancer prevention strategies need to focus on these trends to define a better global prevention. [source]

Placing Indigenous Rights to Self-Determination in an Ecological Context

RATIO JURIS, Issue 2 2002
Barbara Ann Hocking
In this paper the author focuses on Australian land management and in particular on the environmental management issues that could have been prompted by the High Court recognition in 1996 (in Wik Peoples v. The State of Queensland) that native title to land and pastoral leaseholdings can co-exist. Drawing on themes of self-determination and co-existence, the paper looks at more specific topics such as aboriginal title to land,what has been called land rights or native title in Australia,and some implications of that for land, sea and resource management. Central to this analysis are competing theories of Aboriginal land management and links between Aboriginal traditional knowledge and conservation of species. These are illustrated through the marine mammal, the dugong. The Australian debates lead to the Canadian debates and then to Scandinavia and the role of the Sami people in protection and management of the Arctic region. Issues of indigenous self determination inevitably provide an overall theme to these discussions. As a matter of global concern, the paper asks, but does not decide, whether indigenous peoples may manage fragile eco-systems more effectively than outsiders. It maintains that what is important in this context is a broader question. This concerns how culturally inclusive land and resource management can emerge from recognition of indigenous land and human rights and how comparative developments can provide crucial cross-jurisdictional information for future developments and opportunities in the interests of environmental conservation.

Antitrust analysis of supermarkets: global concerns playing out in local markets

Ronald W. Cotterill
This paper reviews the basic components of antitrust analysis for the supermarket industry, including definition of product and geographic markets and the measurement of market power. The analysis of prices and profits in a market structure context remains important, especially in countries such as Australia with very high supermarket concentration. Firm and brand level New Empirical Industrial Organisation models of demand and oligopoly pricing also provide insights for evaluating antitrust claims. Recent research on vertical pricing games and price transmission expand the analysis to market channel pricing issues, including coalescing power by supermarkets and food manufacturers. The issues and approaches explained in this paper are relevant for policy-orientated research on supermarkets worldwide, including Australia. [source]
