Treating dredged sediment is a complex processing and ongoing challenge. To utilize dredged sediment for the landfill or construction purposes, a material fabricated from a mixture of dredged sediment, Portland cement, and fly ash, was cured under room temperature and hydrothermal condition at 180 °C and 0.9 MPa pressure for 16 hours. The response surface methodology was used to evaluate the compressive strength of the material, with the range of factors investigated being the dredged sediments/solid ratio (0.3 - 0.9), cement/fly ash ratio (2 - 4), and water/solid ratio (0.45 - 0.55).

An improved six-node triangular finite element based on a twice-interpolation strategy (TIS) for accurately modeling singular stress fields near crack tips of two-dimensional (2D) cracks in solids is presented. In contrast to the traditional approaches, the approximation functions constructed based on the TIS involve both nodal values and averaged nodal gradients.

This thesis provides solid evidence to support the notion that idiosyncratic volatility plays a significant role in Australian equity markets. Therefore, it should not be ignored but instead should be considered when evaluating the performance of Australian stock portfolios and pension funds. It can also be used to predict Australian economic conditions.

The aim of the present work was to develop a guideline for approving the railway axles made of C35 steel and containing surface and/or in-body defects after manufacturing. First, several through and part-through circular cracks were modeled on the surface and in the body of the axle at its critical cross-section.

This thesis aims to develop finite element models for studying vibration of the 2D-FGM beam. These models require high reliability, good convergence speed and be able to evaluate the influence of material parameters, geometric parameters as well as being able to simulate the effect of shear deformation on vibration characteristics and dynamic responses of the 2D-FGM beam.

Microfibrils and elastin are major constituents of elastic fibers, the assembly of which is dictated by multimolecular interactions.Microfibril-associated glycoprotein-1 (MAGP-1) is a microfibrillar component that interacts with the sol-uble elastin precursor, tropoelastin. We describe here the adaptation of a solid-phase binding assay that defines the effect of divalent cations on the interactions between MAGP-1 and tropoelastin. Using this assay, a strong cal-cium-dependent interaction was demonstrated, with a dis-sociation constant of 2.8 ± 0.3 nM, which fits a single-site binding model.

Chromosomal Instability in Solid Tumors Solid tumors are generally highly aneuploid, containing an abnormal number of chromosomes; these chromosomes also exhibit structural alterations such as translocations, deletions, and amplifications. Again, colon cancer has proven to be a particularly useful model for the study of chromosomal instability (CIN). As described above, some familial cases are characterized by the presence of MIN.
