Overview Urban development presents the greatest driver of soil loss due to sealing-over by buildings, pavement and transport infrastructure. To this end, soil sealing is recognised as one of the major threats to soil. ...

Rainfall in the northeast arid zone of Nigeria is limited and has been found to be declining over the last three decades (Hess et al., 1995). This problem of inadequate rainfall is further exacerbated by runoff especially ...

In this work we present the development of a torque vectoring controller for electric vehicles. The proposed controller distributes drive/brake torque between the four wheels to achieve the desired handling response and, ...

Single and double cycle simulation techniques have been employed to investigate the structure and properties of the heat affected zone in HY-80 steel due to a single submerged arc weld run and to the deposition of a ...

This thesis is concerned primarily with the export marketing performance of the Northern Ireland seed potato industry. The Industry has shown a dramatic decline in exports over the past twenty years, and this thesis ...

A literature review was conducted on several models which have been developed, based on Terzaghi's passive earth pressure theory, to describe the forces acting upon tillage implements during tillage operations. These models ...

The shelf-life of the sweet potato storage root under tropical marketing conditions limits its potential for marketing. This research aimed to identify the physiological characteristics that affect the shelf-life of sweet ...

This thesis charts a research journey through the disciplines of waste chemistry, environmental risk assessment, policy analysis and corporate risk governance since award of the candidate's PhD in 1990. The insights ...

Problem Little research has taken place to investigate fretting fatigue under conditions of variable amplitude loading (VAL) and no research using a complex loading spectra representative of reality. The effect of cycles ...

Struvite causes maintenance, and operational problems due to fouling in wastewater and sludge treatment systems. Struvite formation was initially investigated using a series of jar tests on real and synthetic sludge ...
