   Abstract : This thesis investigates how variations in the oxygen isotopic composition of lake waters in northern Fennoscandia are recorded in lake sediment archives, especially diatoms, and how these variations can be used to infer past changes in climate and atmospheric circulation. Results from analyses of the oxygen isotopic composition of lake water samples (δ18Olakew) collected between 2001 and 2006 show that δ18O of northern Fennoscandian lakes is mainly controlled by the isotopic composition of the precipitation (δ18Op).

   Abstract : Improving productivity is a central challenge in most industries and so also in construction. In many countries, such as Great Britain and US (Egan, 1998; Huang et al., 2009; Teichholz, 2001), governmental reports and research publications have highlighted the slow growth of productivity in the construction industry.
