These muOcIs may be divided into two cliu.ses: the cmpirieiil approach which employ.s extreme value statistics, and the deterministic approach based on perceived mechanisms for nuclcation and growth of damage. More recently. Artificial Neural Networks (ANNs), a iioniletermlnistic t)'pc of model, has been developed lo describe the progression of damage due to pitting corrosion. Wc compare the three approaches above-Statistical, deterministic, and neural network!). Our goal i.s to Illustrate the advantages and disadvantages of each approach, in order that the most reliable methods may be employed in future algorithms for predicting pitting damage functions for engineering structures. To illustrate the difficulty that We face in predicting cumulative pitting damage, we selected a set of data that was collected in the laboratory. Wc compare and contrast the three approaches by reference to this data set.

Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the fabricated catalysts. A UV-Vis spectroscopy was used to monitor the processes of the photochemical and/or electrochemical degradation of lignin. The modified lignin was characterized using Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy, while the intermediates produced during the photoelectrochemical process were analyzed by high-performance liquid chromatography (HPLC). Our study has demonstrated that the innovative approach described in this communication provides a promising and energy efficient, environmentally friendly method for lignin modification and degradation.

With the election of the Coalition Government these trends continued but in a much more extreme form. Moreover, there has been a dramatic marginalisation of the union movement with a strong emphasis on individualism as the appropriate basis for the employment relationship, and this does represent a significant break with the past. Much of the Coalition's reform agenda has its basis in industrial relations reform which was ope rationalised in the provisions of the Workplace Relations Act but many would argue that the die had been cast by Labor. Thus it will be important to consider the extent to which the Coalition's neo-liberal public sector agenda is more extreme than that of Labor. This article focuses largely on the Australian Public Service with some attention to certain Government Business Enterprises. It outlines the Howa...

The literature reveals, however, that support for Cupertino as a union strategy is far from unanimous. Moreover, to combat falling membership levels, union movements have embraced the organising model as a preferred alternative to the servicing model but, it appears, there are potential conflicts between the organising model and a co-operative strategy. The changing status, roles and strategies of Hunter Valley unions has been analysed with the assistance of data gathered from unions and employers in the region. It has been found that the decline of unionism has been somewhat less in the Hunter Region than it has been nationally but, not surprisingly, there are differences between the perceptions of union officials and huma...
