A mechanistic approach to understanding and predicting hydrodynamic disturbance on coral reefs
To understand and predict community dynamics in habitats where physical disturbance is a major cause of mortality, we must understand the frequency and intensity of these events, as well as their differential effects on the community’s structural species. Using a tropical coral reef as a study …

A mechanistic approach to understanding the colour polymorphism in black sparrowhawks (Accipiter melanoleucus)
… system. The aim of this PhD was to explore the mechanistic background of colour polymorphism maintenance in the black sparrowhawk. (i) I performed an experiment in which I test whether there is a morph- and ambient light-dependent crypsis advantage in the black sparrowhawk. I measure the …

A mechanistic approach For predicting the effect of various factors on partitioning between free and bound chlorides in concrete
… pH levels, and chloride sources. A general mechanistic approach that can overcome those limitations is proposed in this thesis based on the concepts of ion-exchange theory for an accurate determination of chloride ingress in concrete under variable environmental conditions. Some of the model …

Response and Performance of Contingency Airfield Pavements Containing Stabilized Material Layers
The mechanistic approach for the design and evaluation of Contingency Airfield Pavements (CAPs) containing stabilized material layers was validated. CAPs are inexpensive pavements built in peacetime and available immediately after an attack for limited aircraft operations. The mechanistic approach …

Effect of temperature and daylength on the phenological development of oats (Avena sativa L.)
… development of oats. The study was based on two approaches. The first was the traditional photothermal approach which describes the interval between phenological events as influenced by thermal and photothermal time. The second was a more mechanistic approach based on the co-ordinated processes …

A Mechanistic-Based Approach to Reduce Biological Adhesion
… coatings to reduce biological adhesion. Recent mechanistic insights suggest that the marine mussel, Mytilus edulis, adheres with proteins that undergo oxidative cross-linking. Our work has focused on taking a mechanistic approach to defeat adhesion with the incorporation of reducing agents into …

Development and interrogation of approaches to modelling xylogenesis with a view towards their suitability for inclusion in Dynamic Global Vegetation Models
… is a solution to this issue by providing a mechanistic approach, RINGSlite.1.0, to represent vegetation sink processes for trees in DGVMs, and so enables the source-driven paradigm to be challenged. To provide this mechanistic approach I first investigate the validity of the sink hypothesis …

Modelling of thermo-mechanical and irradiation behavior of metallic and oxide fuels for sodium fast reactors
… was enhanced by adopting a non-empirical mechanistic approach to the extent possible, so that to increase the ability to extrapolate the existing database with a reasonable accuracy. Computational models to analyze in-reactor behavior of U-Zr and U-Pu-Zr metallic alloy fuel pins and U0 …

Desempenho de pavimentos de baixo custo no Estado do Paraná
… should make a better use of the theoretical mechanistic approach in order to decide the factors to be used in their designs. Materials used in the construction of non conventional pavements are more or less deeply analysed, giving emphasis to fine sandy soils and basaltic clays. Some …

Re-thinking assesment philosophy and practice peer- and self-assesment
… are disadvantaged by the one-size-fits-all, mechanistic approach which gives little consideration to the relational side of learning. This demands correction through a holistic philosophy of learning, where the learning environment caters for personal and social as well as academic …

Towards a mechanistic understanding of the neurobiological mechanisms underlying psychosis
… elucidated. I argue in this thesis that using a mechanistic approach towards understanding psychosis that borrows heavily from the predictive coding framework, can help us understand the relationship between neurobiology and symptomology. In the first results chapter I present new data on a …

Understanding the operatic tenor's legitimate head voice: A comparative study of historical and modern pedagogical approaches
… upper register, and the introduction of a more mechanistic approach to register-blending or -unification as a means of developing the mixed voice source mechanism. In light of more recent discoveries in voice science, the validity of the registerblending or -unification approach has been called …

Modelling and simulation of drying process for ceramic membrane fabrication
… This two-dimensional mathematical modelling approach is able to predict the changes of variables in heat and mass transfer during the drying process. The governing system of fully coupled non-linear partial differential equations of the model was derived from a mechanistic approach where the …

MECHANISTIC STUDY OF CRACK INITIATION AND PROPAGATION IN CROSSLINKED ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENES (UHMWPE) SUBJECTED TO STATIC AND CYCLIC LOADING
… research utilizing the traditional LEFM and EPFM approaches has not yielded a definite failure criterion for UHMWPE. Therefore, an advanced viscous fracture model has been applied to various notched compact tension specimen geometries to estimate the fracture resistance. Results suggest that the …

Development of a general purpose subgrid wall boiling model from improved physical understanding for use in computational fluid dynamics
… was developed using an experimentally based mechanistic approach, where the goal was to accurately capture all physical phenomena that affect heat transfer and occur at the heated surface to correctly predict surface temperatures. The proposed model adopts a similar approach to the classical …
