The application of hydro-mechanical transmissions is recently the trend in agricultural vehicles where a continuously variable transmission ratio has advantages. Hydro-mechanical transmissions provide efficient power transfer while maneuverability is still maintained, and therefore, fuel efficiency is enhanced.

To achieve the aim, the first objective is preliminary experiments on preparation of polypropylene blends with silicone elastomer masterbatch and characterize by analysis of mass composition, mechanical properties, and dynamic mechanical properties to investigate any improvement of properties. The silicone elastomer masterbatch will then be substituted with propylene-maleic anhydride graft copolymer waxes or other compatibilizers.

This research has raised the question of whether the vibration transmission at a wall junction depends on how the wall is excited (by either a sound wave or a mechanical shaker). The aim of this research is to investigate this question and hence contribute to the revision of the series of standards. Villot and Guigou-Carter (2000) have considered this problem but their equations (10) and (13) appear to be in error. This research will endeavour to derive the correct equations and r epeat Villot and Guigou Carter’s calculations.

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

Epigenetic defects (gain or loss of DNA methylation) of the human ICR1 11p15 domain result in two opposite foetal growth disorders (BWS and SRS) depending on which parental allele is affected. A few deletions within ICR1 have been reported in familial BWS cases with ICR1 gain of methylation, however the mechanism(s) of the DNA methylation defects at ICR1 remains largely unknown in most BWS and SRS patients.

The aim of this study is to explore and develop methods of controlling colour while overcoming many of the inherent problems in the processing. Because to the enormous variety of paper available, testing for printing was narrowed to primarily 100% cotton papers. The negative was critical in realising the full potential of the salt prints tonal range. The film tested was limited by availability in the Australian market. The research into various films to create digital output negatives proved to be complex and time consuming.

Understanding mechanical properties of healthy and unhealthy cerebral vessels is a key element in the development of their science and the relevant clinical diagnosis, prevention and treatment. Thirteen healthy samples were obtained from 23 middle cerebral arteries. The changes of force and deformation until the vessel rupture were recorded using a biaxial device.
