Abstract:

Interactions between nesting birds and invertebrates are a common, yet poorly understood ecological phenomenon. Many of these types of interactions are close and prolonged, and therefore potentially critical to one or both of the species involved in the interaction. However it is unusual for the nature of the interaction to be evaluated in a manner that reveals the impact of the relationship on both parties to the interaction. This study examines two relationships between nesting birds and invertebrates, both of which involve the hooded parrot (Psephotus dissimilis), a small grass parrot that

Abstract:

Eurypanopeus depressus and Eurypanopeus dissimilis, two estuarine species of xanthid crabs, were raised under laboratory conditions. Four zoeal stages and one megalopal stage were observed in both species. The larvae of E. dissimilis have a longer intermolt period and grow to a larger size than E. depressus. E. dissimilis can be distinguished from E. depressus on the basis of three main features: 1) greater telson armature, 2) longer endopod in relation to the protopod of the antenna in the fourth zoeal stage, and 3) presence of the frontal horns on the carapace of the megalopa.

Abstract:

All interfaces offer resistance to heat transport. As the size of a device or structure approaches nanometer lengthscales, the contribution of the interface thermal resistance often becomes comparable to the intrinsic thermal resistance offered by the device or structure itself. In many microelectronic devices, heat has to transfer across a metal-nonmetal interface, and a better understanding about the origins of this interface thermal conductance (inverse of the interface thermal resistance) is critical in improving the performance of these devices.

The colour size effect is an important aspect of colour appearance phenomenon, in which the colour appearance is changed according to different sizes of the same colour stimulus. Although colour appearance has been actively researched over the last 20 years and models have been developed capable of predicting the colour appearance under a wide range of viewing conditions, the colour size effect was not taken into account due to lack of reliable colour appearance data for colours with various sizes. This lead to great difficulty for industry for faithfully reproducing colours between dissimilar

Non-contact lap splices placed within a single concrete placement are often used and have been studied in previous research projects. However, non-contact lap splices used with each bar in a different concrete placement such that there is a cold joint between the bars, have not been investigated. This situation is found in the repair of adjacent box beam bridges and in the construction of inverted T-beam systems, among others. It is vital to understand whether the same mechanisms are present across a cold joint with two different types of concrete as are present in traditional non-contact lap

Abstract:

Two different aluminium alloys, AA6111 (Al-Mg-Si) and AA7055 (Al-Mg-Zn), were chosen as the aluminium alloys to be welded with DC04, and two welding methods (USW and FSSW) were selected to prepare the welds. Selected pre-welded joints were then annealed at T=400 - 570oC for different times. Kinetics growth data was collected from the microstructure results, and the growth behaviour of the IMC layer was found to fit the parabolic growth law. A grain growth model was built to predict the grain size as a function of annealing time. A double-IMC phase diffusion model was applied, together with gra

Abstract:

The challenges in the deposition of dissimilar materials are mainly related to the large differences in the physical and chemical properties of the deposited and substrate materials. These differences readily cause residual stresses and intermetallic phases. This has led to the development of functionally graded materials which exhibit spatial variation in composition. Laser direct metal deposition due to its flexibility, it offers wide variety of dissimilar and functionally graded materials deposition. Despite considerable advances in process optimization, there is a rather limited understand
