1. Decay Chains of Fast Alpha Emitters in the Actinide Region
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

2. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach
University essay from Lunds universitet/Geologiska institutionenAbstract : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. READ MORE

3. CFD Analysis of the Flow Around a Paraglider Wing
University essay from KTH/Teknisk mekanikAbstract : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. READ MORE

4. Macrosegregation Prediction in Continuously Cast Steel Slabs
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : A prediction model [3] of macrosegregation in continuously cast steel slabs developed by Barber et al from Corus Teesside Technology Centre, UK as an extension of the work of Miyazawa and Schwerdtfeger [4] is presented in this thesis. Improvements have been made in the model to include the effect of many bulges between the supporting rolls induced by the ferrostatic pressure exerted on the solidifying shell by the liquid phase, which were approximated following a deflection of an elastic beam model.

5. Modelling Time-Dependent Effects for Segmentally Constructed Prestressed Concrete Bridges
University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologiAbstract : Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. READ MORE
