Impacts and drivers of insect herbivory on element cycling in forests globally

The effects of insect herbivores on forest functioning are not well understood even though they can have important impacts on ecosystem processes by intercepting foliage before resorption and depositing nutrient-rich materials to the soil. In this thesis, I investigated the impact and drivers of insect folivores on carbon (C), nitrogen (N), phosphorus (P) and silica (Si) cycling in broadleaf fores

Interaction between freestream turbulence and vortex shedding for a single tube in crossflow

The effect of freestream turbulence on the flow past a circular cylinder (tube) was studied experimentally for Reynolds numbers between 2 x 104 and 6 x 104. Investigations were carried out for uniform (non-turbulent) flow and for turbulent flows having turbulence intensities between 1.3 and 4.1%. The variations in the pressure forces and shedding frequencies were found to be related to the variati
