17. Development and Evaluation of Preparation Methods for the Analysis of Cell Membranes Using Time-of-Flight Secondary Ion Mass Spectrometry
Abstract : The aim of this work was to evaluate and develop methods for preparing dry samples for TOF-SIMS analysis of cell membranes. For correct interpretation of the analysis data, an understanding of the effects that the preparation method has on the morphology and chemical structure of the sample must first be obtained.

18. Modeling of Gas Flows in Steelmaking Decarburization Processes
Abstract : The purpose of the current study is to increase the understanding of different steelmaking processes at the decarburization stages by use of mathematical modeling. More specifically, two De-Laval nozzles from a VOD (Vaccum Oxygen Decarburization) process, which is used for producing stainless steels with ultra-low carbon grades, was investigated for different vessel pressures.

19. On Suction Box Dewatering Mechanisms
Abstract : In previous studies on suction box dewatering, three mechanisms were identified that determine the dry content of a web, viz. web compression, displacement of water by air and rewetting. READ MORE

20. Quantum Coherence and Quantum-Vacuum Effects in Some Artificial Electromagnetic Media
Abstract : The author of this thesis concentrates his attention on quantum optical properties of some artificial electromagnetic media, such as quantum coherent atomic vapors (various multilevel electromagnetically induced transparency vapors) and negative refractive index materials, and suggests some possible ways to manipulate wave propagations inside the artificial electromagnetic materials based on quantum coherence and quantum vacuum effects. In Chapters 1 and 2, the author reviews the previous papers on quantum coherence as well as the relevant work such as electromagnetically induced transparency (EIT), atomic population trapping and their various applications.
