1. Summer Climate Variability during the Past 1200 Years in Central Scandinavia – A Tree-Ring Perspective
Sammanfattning : To set the current 20th century warming in a long-term context, significant efforts have been made to reconstruct hemispheric-to-global temperatures beyond the instrumental period. Tree-rings, which have annual resolution and can be precisely dated, have been widely used to infer past climate variability. LÄS MER
2. Synthesis of Transition Metal Aluminides from Elemental Powder Mixtures
Sammanfattning : Structural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance.

3. Glaciers and climate in northern Sweden during the 19th and 20th century
Sammanfattning : Our understanding of the climate of northern Sweden during the late Holocene is largely dependent on proxy-data series. These datasets remain spatially and temporally sparse and instrumental series are rare prior to the mid 19th century. LÄS MER
4. Effects of abiotic and biotic factors on hatching, emergence and survival in Baltic salmon (Salmo salar L.)
Sammanfattning : This thesis deals with important factors that affect the temporal organization of emergence and early survival of Baltic salmon (Salmo salar L.). The study population was obtained from the Norrfors hatchery (63°50'N,20°05'E), Umeälven (Ume river) in Northern Sweden. LÄS MER
5. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics
Sammanfattning : Multi-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium as the tracer species, in sooting environments such as in diesel engines.
