River bifurcations: key processes, timescales and evolutionary trajectories
… The first part of this PhD thesis focuses on the key physical processes underlying the evolution of river bifurcations, along with their characteristic timescales and the different resulting evolutionary trajectories. These analyses are carried out mostly by means of a novel one-dimensional …

Elevation Effects on Key Processes of Carbon Cycling in South Ecuadorian Mountain Forests
Diese Studie über Wälder Süd-Ecuadors hat das Ziel große Wissenslücken zu füllen, den Kohlenstoffkreislauf montaner Regenwälder in einer Meereshöhe von 1000 bis 3000 m betreffend. Besondere Aufmerksamkeit wurde dabei auf den bisher unbekannten Kohlenstoffumsatz durch Feinwurzeln, Stammholzzuwachs …

An investigation of the limited distribution of the grazing lawns in Hluhluwe-Umfolozi Park, South Africa
… lawns were investigated. A conceptual model of key processes considered necessary for the formation and persistence of lawns in HUP was developed. Key processes include both frequent and non-selective grazing during the growing season Based on observations that the distribution of grazing lawns …

Characterising the porosity of multi-component mixtures in rotary mills
… important parameter is vital to understanding key processes that occur in porous media, such as fluid transport. This is because porosity is strongly related to the permeability of porous media.

A hybrid mathematical model of fungal mycelia: tropisms, polarised growth and application to colony competition
… modelling has provided a means through which key processes can be isolated to analyse and simulate a target system to allow observations and form predictions regarding unknown phenomena. Numerous models of fungal colonies have been produced and are generally categorised into two main groups; …

dreamtime uncapitalised, -joining our own dots .
… inter-disciplinary learning. Drawing on key processes in art‐making, this project recorded the development of phenomenological thoughts and concepts that arose during the creation of a variety of cognitive spaces, chiefly the making of artworks. It employs and expresses the emergent …

The Effect of Arginine Vasotocin on Cryoprotectant Production during Freezing in the Pacific Chorus Frog, Pseudacris Regilla
… effects as well as regulate several key processes involved in fluid and solute transportation. Although one prior study suggested that AVT is not involved in responses to freezing, I measured AVT levels during freezing and injected an AVT antagonist to see if it would affect the …

nerd: A Neuron-Specific Gene in Drosophila Melanogaster Related to Vertebrate GAP-43
… GAP-43 has been implicated in a number of key processes in neural development and synaptic behavior. There have been no reports identifying an invertebrate molecule with homology to GAP-43. In this study we have begun to explore the biochemistry and genetics of the Drosophila gene nerd, …

Innovating the standard procurement process
… caused DoD to seek high levels of improvement in key processes, such as procurement, because of the high costs and long cycle times associated with contracting activities. The SPS is intended to increase efficiency by automating the process. However, simply automating the process may not bring …

Ecology of acidification and recovery in Welsh upland streams
… tested the effects of acidification on two key processes in stream ecosystems, benthic algal grazing and leaf decomposition. Grazer impacts on algal abundance were generally feeble and largely unaffected by acid stress. Leaf litter decomposition was impaired by acidification, due largely to …

Six Sigma process improvements and sourcing strategies following factory fire
… during the recovery uncovered inefficiencies in key processes. One of the areas that increased in importance following the fire was magnet assembly. The first half of this thesis (Chapter 3 through Chapter 6) applies Raytheon's Six Sigma framework to the magnet assembly process in an effort to …

How do existential counselling psychologists and psychotherapists feel they construct a sense of being attuned to their clients? A grounded theory study.
… illuminated as a result of this study. The two key processes found were being empathic and attuned and being within and between. The findings highlight the importance of existential practitioners’ use of their self when sensing, understanding and being with their clients on a non-verbal and …

Multiscale Mathematical Modelling of Cancer Invasion
… in order to gain a better understanding of the key processes involved during invasion. At first, we tested our modelling concept by applying a level-set method to a moving boundary problem. Later, a multi-scale mathematical model of cancer invasion was developed by coupling the urokinase …

Experimental Study of Pathogenic Microorganism Resuspension from Mobile Bed Sediment in Irrigational Canals
… water is associated with sediment through two key processes: resuspension and attachment. This dissertation reports two experimental and one field studies to quantify the role of sediment in microbial water quality.The first experimental study focused on the viral pathogen resuspension from …

The Colonization Strategies of Nontypeable Haemophilus influenzae - Bacterial Colonization Factors and Vaccine Development
… novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity. We have shown that the NTHi virulence factor Protein E mediates innate immune evasion by interacting with the C-terminus of host …
