1. The Influence of Atmospheric Turbulence on Barrier Sound Reduction
Abstract : Numerical modelling and measurements are used for studying the reduced performance of a noise barrier, caused by a turbulent atmosphere. The turbulence scatters the sound, which leads to an increased noise level in the acoustic shadow region behind the barrier. READ MORE

2. Effects of anasthesia on esophageal sphincters
Abstract : The esophageal sphincters constitute the anatomical protection against pulmonary aspiration. The aim of this thesis was to study the esophageal sphincters and how they are affected by different components of emergency anesthesia using high-resolution solid-state manometry.The effect of propofol (0.

3. Taking Pressure of Anaplastic Thyroid Carcinoma : Molecular Studies of Apoptosis and Interstitial Hypertension
Abstract : Molecular mechanisms in the development and progression of thyroid carcinomas are still not fully understood. In the present thesis the highly malignant anaplastic thyroid carcinoma (ATC) was used to study regulation of apoptosis and tumor interstitial fluid pressure (IFP). READ MORE

4. Effects of anesthesia on esophageal sphincters in obese patients
Abstract : The lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) play a central role in preventing regurgitation and aspiration. The aim of this thesis was to evaluate the UES, LES, esophageal (E) and barrier (Br) pressures (P) using high resolution solid state manometry (HRSM). READ MORE

5. Characterization of WC-Co tools used for machining of Alloy 718 under the influence of high-pressure coolant supply
Abstract : The use of high-pressure jets for supply of coolant to the cutting zone has the potential to significantly increase the productivity and process stability when machining difficult-to-cut materials such as Ni-based superalloys. Apart from better chip-breakability, the jets enable the coolant to reach closer to the cutting edge and hence enhance its capability to dissipate heat. READ MORE
