Abstract:
This thesis examines the behaviour of single 60mm and 114mm segmented tubular steel piles driven and placed into loose sand and loose sand overlying clay. The soil was placed and instrumented under controlled conditions in a 3.0m diameter by 3.0m deep concrete tank. The 60mm pile was dynamically driven using a pneumatically controlled driving rig, whilst the 114mm pile was driven at a constant rate of penetration via a hydraulic jack. The static and dynamic axial load distributions were monitored for the 60mm pile. The variation in local shaft friction and radial effective stress were monitore

This project consisted of a series of short stories which worked together creating a larger fictional piece in the form of a non-continuous narrative. This non-continuous narrative is in the tradition of Sherwood Anderson's Winesburg, Ohio, and Louise Erdrich's Love Medicine. The stories in this type of fiction are connected by similar themes and settings, allowing the reader to participate directly in the creative process. The reader helps create the fiction by drawing his or her own conclusions about the characters and places from between the individual stories. By involving the reader more

Abstract:
Coastal sand dunes are common in Britain, especially along western Atlantic coasts, and archaeological sites are well preserved under blown sand. One of the questions is how Holocene palaeoclimate variation influences patterns of settlement establishment and abandonment. Few studies of coastal sites have included palaeoenvironmental evidence, and even fewer include securely dated stratigraphy. This study uses a multi proxy approach to investigate two main and five minor coastal sites in Cornwall, with molluscs analyses being the principal analytical method.

Abstract:
Slow sand filtration requires low turbidity water for effective operation. In most cases this means pretreating the raw water to reduce its turbidity. Lately horizontal gravel filters have become very popular as a means of pretreatment. They are simple to operate, have a large mass storage capacity, and can cope with high turbidity shock loads. However, cleaning them can be a problem. An alternative pretreatment, which this study is concerned with, is upflow sand roughing filtration. It has the potential advantages of simple design, ease of operation and cleaning, and low area requirements. A

Although Cambodia banned sand exports in 2017, under-regulated sand extraction in rivers across the country continues, driven by demand from rapid urbanization and land reclamation around Phnom Penh.

At the same time, the sand boom in Cambodia has created a demand for labour, offering opportunities to rural Cambodians who have few other

Abstract:
Over the life of an oil and gas reservoir, it is likely to encounter sand production. In offshore production fields, as there are lack of processing facilities nearby, gas, liquid and sand are often transported together in long distance pipelines. The existence of sand could accumulate in the pipelines under inappropriate operation condition and eventually will lead to a blockage. Thus, to design such systems requires knowledge on how sand is transported, when and where it will accumulate.

In order to achieve stability and predictability of movement, stepper motor driven wheels were chosen as the steering method.

This thesis focuses on proposing a novel comprehensively predictive modelling framework for granular materials which builds on the hydrodynamic procedure to satisfy the principles of thermodynamics, mass, momentum and energy conservations. In developing our physical arguments we recognise that complexity of the macroscopic mechanical response of granular media is mainly a result of kinematic degrees of freedom in granular scale. We therefore employ the original concept of two-stage irreversibility by Jiang and Liu (2009) and consider an energy sink from the mesoscopic granular entropy level to

A study on the possible use of melted waste thermoplastics to stabilize soils, and produce plastic-soil structural composites is presented.

An extensive experimental program was conducted to examine the strength and creep characteristics of different plastic-sand compositions. It was found that increasing plastic content in the sand results in stronger, and stiffer soils with negligible creep deformations for loads which are at least 50% of the strength of the composite. I

Moult in birds is a critical yet often underrated component of a birds' annual life cycle together with breeding and migration. A good understanding of the moult strategy of a species is important for its conservation because key moulting grounds must be protected to allow this component of the life cycle to be undertaken. Lesser Sand Plovers, Greater Sand Plovers and Terek Sandpipers are among the least known of the commonly encountered long-distance migrant waders in Africa and Australasia.
