Abstract:

Collapsible soils covers naturally over 10% of the earth’s surface. This makes it a global problem and it is essential that engineers identify and control collapsibility prior to construction. Hence in this thesis, a study on identification, evaluation and control of soil collapsibility is undertaken. Four geologically different soils have been tested at five compactive variables from optimum moisture content (OMC). The soils tested include: Brown inorganic silty clay of low plasticity (A); White inorganic silt with slight plasticity (B); Red inorganic clay of intermediate plasticity (C); and

In order to investigate the kinetics and selectivity of the liquid phase nitration of phenol, reliable procedures for the production of the nitrating agents N<sub>2</sub>O<sub>5</sub> and CINO<sub>2</sub> were established. Production of N<sub>2</sub>O<sub>5</sub> was achieved <i>via</i> on-line mixing of NO<sub>2</sub> (1%) with O<sub>3</sub>(~5%) in the 2:1 ratio in a darkened reaction vessel. CINO<sub>2</sub> was produced by conversion of N<sub>2</sub>O<sub>5</sub> using NaCI solution (4 M).

Abstract:

Tidal meandering channels are ubiquitous features of tidal landscapes and play a fundamental role on the eco-morphodynamic evolution of these environments. However, only a handful of papers provide details on tidal meander planimetric shape, morphometric characteristics and morphodynamic evolution, and the internal achitecture of tidal meanders has not been explored in detail. Moreover, the morphodynamic evolution of tidal meanders and the related sedimentary products have often been interpreted on the basis of the well developed models and theories existing for their fluvial counterparts, des

Abstract:

An understanding of arsenic interactions with mineral surfaces in aqueous environments is important if arsenic transport in groundwater is to be predicted. This study contributes to the understanding of arsenic (As(V)) adsorption onto goethite (alpha-FeOOH) by linking equilibrium batch experiments and dynamic column experiments to the use of atomistic modelling. In this way the mechanisms of arsenic adsorption onto goethite surfaces ore explored. The equilibrium batch experiments illustrate the declining affinity of As(V) as a negatively charged oxy-anion to sorption on goethite, with increasi

Over the last few decades, the specifications for wrought aluminium products have become increasingly strict.

The material properties are controlled by the microstructure. Hence the necessity for a modern aluminium plant to control the microstructure of the finished product through the processing parameters. This microstructure strongly depends on the microstructures produced during each of the processing steps. Therefore, it is ne

Cohesive sediment in estuaries can act as either a source or a sink of many pollutants, such as nutrients and heavy metals.

Aquatic sediments are the recipients of a continual rain of organic debris from the water column. The decomposition reactions within the sediment and the rates of material exchange between the sediment and water column are critically moderated by the transport processes within the sediment. The sediment and solute movement induced by burrowing animals bioturbation and bioirrigation far exceed abiotic transport processes such as sedimentation burial and molecular diffusion.

This study is part of the Marie Curie research network LIMOUSINE, which was set up to model thermoacoustic instabilities in the combustor chamber of gas turbines.

Abstract:

Functional Magnetic Resonance Imaging (fMRI) is a common technique for imaging brain activity in humans. However, the fMRI signal stems from local changes in oxygen level rather than from neuronal excitation. The change in oxygen level is referred to as the Blood Oxygen Level Dependent (BOLD) response, and is connected to neuronal excitation and the BOLD response are connected by the neurovascular coupling. The neurons affect the oxygen metabolism, blood volume and blood flow, and this in turn controls the shape of the BOLD response. This interplay is complex, and therefore fMRI analysis often

Polar regions have recently been subject to warming at almost double the global average, causing the retreat of glacier and ice cover and exposing large expanses of terrestrial habitats.

However, the reliance of the microbial community on ancient carbon pools, external sources (e.g. deposition) of nutrients, photosynthesis and nitrogen fixation is unknown. Further

Abstract:

A number of studies have focused on urban trees to understand their mitigation capacity of air pollution. Present PhD project aims to describe Particulate Matter (PM) accumulation on tree leaves in a specific urban environment as case study, both in terms of quantity and quality. Furthermore, experimental data obtained from laboratory analysis are crossed with an air pollution model designed for urban environments, in order to relate PM deposition to main polluting sources. PM deposition on Quercus ilex leaves was quantitatively analyzed in four districts of the City of Terni (Italy) for thr

Abstract:

The introduction of computer-aided tools into the product development process allows improving the quality of the product, evaluating different variants of the same product in a faster way and reducing time and costs. They can play a meaningful role also in designing custom-fit products (especially, those characterized by a tight interaction with the human body), increasing the comfort and improving people’s quality of life. This thesis concerns a specific custom-fit product, the lower limb prosthesis. It is part of a research project that aims at developing a new design platform centred on

Abstract:

The sinking of dense shelf waters down the continental slope (or “cascading”) contributes to oceanic water mass formation and carbon cycling. Cascading is therefore of significant importance for the global overturning circulation and thus climate. The occurrence of cascades is highly intermittent in space and time and observations of the process itself (rather than its outcomes) are scarce. Global climate models do not typically resolve cascading owing to numerical challenges concerning turbulence, mixing and faithful representation of bottom boundary layer dynamics. This work was motivated by
