Ultrasound tomography is a non-invasive imaging technique that seeks to determine the internal distribution of acoustic properties within the body by analyzing measured ultrasound data. Based on the distorted Born iterative method (DBIM), this work suggests employing resolution-jumping and beamforming techniques for tomographic ultrasound imaging.

This study focuses on the stability of nano-emulsions produced by phase inversion temperature method using n-Decane and n-Dodecane as the dispersed phase and pure water/brine as the aqueous phase (continuous phase). A non-ionic surfactant (Brij 30) was used in the preparation of the nano-emulsions. Three different types salt namely \(NaCl\), \(KCl\) and \(MgC{l_2}\) were used at different concentrations.

Research purposes: We consider some inverse source problems for parabolic equations, focus on three topics: First, we give stability estimates. Second, we propose regularization methods to solve these problems. Third, we set up algorithms and give numerical examples to illustrate the performance of the proposed regularization methods in this thesis.

The superabsorbent polymers based on acrylic acid have been prepared in the presence of ammonium persulfate (APS) as initiator and N,N-methylene- bis- acrylamide (MBA) as crosslinking agent. The suspension polymerisation occurred in aqueous drops dispersed in toluene and stabilised by sorbitan monooleate. Some effects on the swelling degree and size particles such as concentrations of MBA and initiator, neutralization degree (Dn) were studied. Swelling degree 405g/g, reach maximum at 85◦C and 0.09% crosslinking agent, 1.

This thesis investigates the tax implications of U.S. companies that employ the practice of corporate inversion. I have selected eleven companies that have utilized this strategy, and have conducted research to determine if corporate inversion results in a tax savings when compared to a matched set of non-inversion companies. For my research, I will compare the tax liabilities of the selected companies both before and after the inversion has occurred.

The results of my statistical analysis revealed that only two variables (the number of days per year with thunderstorms and the total water equivalent precipitation) exhibited significant relationships with the percentage of work commuters who cycled or walked. Furthermore, the number of days per year with thunderstorms exhibited a strong inverse relationship, meaning that thunderstorms deterred workers from cycling or walking to work.
