21. Mathematical modelling of flow through thin curved pipes with application to hemodynamics
Abstract : The problem of mathematical modelling of incompressible flows with low velocities through narrow curvilinear pipes is addressed in this thesis. The main motivation for this modelling task is to eventually model the human circulatory system in a simple way that can facilitate the medical practitioners to efficiently diagnose any abnormality in the system.

22. Opening New Radio Windows and Bending Twisted Beams
Abstract : In ground based high frequency (HF) radio pumping experiments, absorption of ordinary (O) mode pump waves energises the ionospheric plasma, producing optical emissions and other effects. Pump-induced or natural kilometre-scale field-aligned density depletions are believed to play a role in self-focussing phenomena such as the magnetic zenith (MZ) effect, i. READ MORE

23. Mold2012 : a new gravimetric quasigeoid model over Moldova
Abstract : In order to be able to use the operational Moldavian GNSS Positioning System MOLDPOS efficiently for the determination of normal heights in surveying engineering, e.g. during the construction of a road, an accurate quasigeoid model is needed. READ MORE

25. Improved seed handling techniques for Juniperus polycarpos : implications for active restoration of degraded Juniper forests in Iran
Abstract : Juniperus polycarpos (K. Koch) is one of six native juniper forest tree species in Iran whose population size is declining continuously. The ultimate aim of the research presented in this thesis was to increase the regeneration potential of J. READ MORE
