1. Anaerobic Digestion of Solid Residues on the Bolivian Altiplano
Sammanfattning : Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. LÄS MER
2. Quantitative Trait Evolution in a Changing Environment in a Seed Beetle
Sammanfattning : During the last decades the climate has been changing more rapidly than in the preceding periods. This is for instance characterized by an increase in temperature. Interestingly, such changes in the environment are not necessarily constant over time as they often show high levels of fluctuation. LÄS MER
3. Temperature Gradient Instabilities and Transport in Toroidal Plasmas
Sammanfattning : This thesis focuses on temperature gradient driven modes and their implications for heat and particle transport in toroidal plasmas. Some of the consequences of including an ion impurity species in a model for low frequency electrostatic modes and fluctuation driven transport are discussed. LÄS MER
4. Resistive studies of vortices and fluctuations in single crystal YBa2Cu3O7-
Sammanfattning : High-temperature superconductors have been intensely studiedsince the discovery, almost 20 years ago. Their layeredstructure, extreme type-II behavior, large anisotropy, andstrong fluctuations have led to a large number of new andinteresting problems. LÄS MER
5. The paramagnetic Meissner effect
Sammanfattning : The low field dynamics of some high temperature superconductors have been studied experimentally, using SQUID magnetometry. The research has been focused on the so called Paramagnetic Meissner Effect (PME), a phenomenon seen in some high temperature superconducting cuprates. LÄS MER
