Australia’s transport greenhouse gas (GHG) emissions are high and continue to grow, with current levels approximately one-third higher than in 1990 and increasing by around 1% annually. Efforts to curtail and reverse this growth have not been successful to date. In recent times, national policy development and debate has centred on market-based mechanisms to reduce GHG emissions, namely an emis...

The cost of providing air transportation for passengers and cargo to, from, and within the European Union was scheduled to increase in 2012 due to the EU Emission Trading Scheme. The European Union (EU) has legislated that aircraft landing or taking off from EU airports are subjected to the Emission Trading System (ETS) and are levied a charge for the estimated amount of carbon dioxide (CO2) ge...

Air transport has become a vital component of the global economy. However, greenhouse gas emissions from this sector have a significant impact on global climate, being responsible for over 3.5% of all anthropogenic radiative forcing. Also, the accrued visibility of aircraft emissions greatly deteriorates the public image of the industry. In this context, incentive-based regulations, in the form...

The proteins of the Ets family are transcription factors involved in signal transduction, cell cycle progression, and differentiation. In this study, we report that thyroid cell neoplastic transformation is associated with a dramatic increase in ETS transcriptional activity, which is dependent on the accumulation of Ets-1, Ets-2, and other Ets-related proteins. Inhibition of ETS transactivation...

Electron transport activity at the cell surface of intact oat seedlings (Avena sativa L. cv Garry) was examined by measuring the oxidation and/or reduction of agents in the medium bathing the roots. Oxidation of NADH with or without added electron acceptors and reduction of ferricyanide by an endogenous electron donor were detected. The activities appear to be due to electron transfer at, or ac...

Although recent studies have suggested that CC chemokine CCL2 may directly affect the angiogenesis, the signaling events involved in such regulation remain to be determined. This study investigated a potential signal mechanism involved in CCL2-induced angiogenesis. Our in vitro and in vivo (hemangioma model of angiogenesis) experiments confirmed earlier findings that CCL2 can induce angiogenesi...

Top-down and bottom-up models have been use to sustain climate policy decisions and evaluate the costs of achieving a certain level of abatement. However, due to their different concepts the costs estimated by the two approaches usually differ, with top-down calculating higher costs. These divergences can also contribute to the definition of different strategies of reduction based on the model ...
