1. Towards Energy-Efficient Drinking Water Production using Biomimicry
Sammanfattning : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. LÄS MER
2. Influence of fractures and air bubbles on the pressure distribution embankment dams
Sammanfattning : In some large embankment dams unexpected pore pressure distributions within the core have been observed. As an example, the piezometer pressures in WAC Bennett Dam, Canada, which rose for about four years after the reservoir was filled, were steady for two years and subsequently declined. LÄS MER
3. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas
Sammanfattning : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. LÄS MER
4. Excess pore water pressure generation in fine granular materials under cyclic loading -A laboratory study
Sammanfattning : Abstract Excess pore water pressure can be generated in subgrades of both railway and pavement sub-structures under cyclic loading caused by heavy traffic. When saturated subgrades are subjected to cyclic loading, excess pore water pressures accumulate over time which then could lead to migration of particles into overlying layers. LÄS MER
5. Diffusion of Water in Foods during Heating
Sammanfattning : The overall aim of this research was to improve the knowledge of diffusion of water in foods during heating, so that the final quality of foods after heat processing could be predicted and controlled. The work consisted of three main parts. The first part involved the development of a method to study the diffusion. LÄS MER
