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.

Soil erosion strongly affects crop yield, undermines the long term productivity of farm land and sustainability of farming system, and poses a major threat to the livelihood of the farmers and rural communities. The United Nations Environmental Program reported that the productivity of soil has reduced and resulting in economically unfeasible cultivation on about 20 million hectare of land each year due to soil erosion and resulting degradation of land.

In this document, we present a simplified geometrical model (0D model) for the in-core corium propagation transient. A degraded core with a formed corium pool is used as an initial state. This state can be obtained from a simulation computed with an integral code.

The thesis aims to propose some control techniques for mobile target Robot-camera. After that, I studied some of the torque control techniques of joints for the Robot-camera system sticking to the mobile target and the Robot-camera system, paying attention to the motivating motor sticking to the mobile target. Finally, the author also proposed some control algorithms for Robotic-camera arm system with irregular model, external noise and preventing system degradation, using nonlinear sliding controller (TSMC) in combination with Artificial neural networks to estimate uncertain numbers.

As human choriocarcinoma cells display many of the biochemical and morphological characteristics reported for in utero invasive trophoblast cells we have studied cho-lesterol supply from high density lipoproteins (HDL) to these cells.Binding properties of 125 I-labeled HDL sub-class 3 (HDL3)at4
C were similar for BeWo, JAr, and Jeg3 choriocarcinoma cell lines while degradation rates at 37
C were highest for BeWo.

We briefly review the metabolism of the chloroplast stroma, and describe the structural modelling technique of elementary modes analysis. The technique is applied to a model of chloroplast metabolism to investigate viable pathways in the light, in the dark, and in the dark with the addition of sedoheptulose-1,7-bisphosphatase (nor-mally inactive in the dark).

Pyrimidines are important metabolites in all cells. Levels of cellular pyrimi-dines are controlled by multiple mechanisms, with one of these comprising the reductive degradation pathway. In the model invertebrateCaenorhabditis elegans, two of the three enzymes of reductive pyrimidine degradation have previously been characterized.

Arylsulfatase A is an oligomeric lysosomal enzyme. In the present study, we use this enzyme as a model protein to examine how heteromerization of wild-type and misfolded endoplasmic reticulum-degraded arylsulfatase A polypeptides affects the quality control of wild-type arylsulfatase A subun-its.

To provide a basis for the development of approaches to treat elastin-degrading diseases, the aim of this study was to investigate the degradation of the natural substrate tropoelastin by the elastinolytic matrix metallopro-teinases MMP-7, MMP-9, and MMP-12 and to compare the cleavage site specificities of the enzymes using complementary MS techniques and molec-ular modeling.

D-Amino acid oxidase (DAAO; EC 1.4.3.3) has been proposed to play a main role in the degradation ofD-serine, an allosteric activator of the N-methyl-D-aspartate-type glutamate receptor in the human brain, and to be associated with the onset of schizophrenia.
