Composting is a useful waste treatment for environmental problem, but composting experiment is challenging due to large-scale requirement. Thus, laboratory-scale reactor is of interest for composting experiment. The capability of laboratory-scale reactor to simulate large-scale composting was determined by assessing the quality of produced compost via germination index.

In hydrogenated amorphous silicon/crystalline silicon (a-Si:H/c-Si) heterojunction (HJ) solar cell, the high contact resistance or high Schottky barrier at the back-surface field (BSF)/Indium Tin Oxide (ITO) is prejudicial to the majority carrier collections process, as it degrades the fill factor (FF), which in turn, cell efficiency.

The research herein builds on the work of Rojek (2003) and further investigates the bioremediation of NOM wastes. The aim of this research was to evaluate the effectiveness of selected white-rot fungi and yeast for the biodegradative removal of concentrated NOM from solution. The effectiveness of the white-rot fungus P. chrysosporium ATCC 34541 for the biological degradation of different batches of MIEXTM NOM concentrate and the effects of different characteristics of the NOM on the process and thus the resistance of the NOM to microbial removal were investigated.

This research reviews the current knowledge and contributes to research efforts of rail track degradation models. The main focus is to understand the behaviour of each model, taking into consideration the variables and factors. This research presents models to predict the tram track degradation of Melbourne network based on its influencing factors. It improves decision-making on degradation models in order to optimise and prioritise maintenance practices and minimise track defects.

The broad aim of this research project is to optimize planned and emergency maintenance tasks and timings for tram tracks. Consistent with that broad aim, the following specific objectives are identified: Understand the factors affecting the degradation of tram tracks; develop a degradation prediction model for tracks as a function of the influencing factors; evaluate the time and type of maintenance required for deteriorated rail tracks.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

While it is recognised that knitted fabrics may have their place in firefighting PPC, especially for undergarments, from the point of view of fire performance, strength and presentation, woven fabric constructions appear to be more suitable for work wear applications. Hence, this study is concerned with developing and testing a range of functional, woven Station Wear fabrics designed to enhance flame protection, durability and thermo-physiological comfort properties. In trying to improve all three aspects, a compromise in the properties of fabrics developed would be very likely.
