11. The Influence of Dopants on the Growth of Diamond by CVD
Sammanfattning : Diamond is an important material in many industrial applications (e.g., machining of hard materials, bio-electronics, optics, electronics, etc.) because of its exceptional properties such as hardness, tolerance to aggressive environments, compatibility with human tissues, and high carrier mobility.

12. Models of Mechanics and Growth in Developmental Biology: A Computational Morphodinamics approach
Sammanfattning : Recent evidence has revealed the role of mechanical cues in the development of shapes in organisms. This thesis is an effort to test some of the fundamental hypotheses about the relation between mechanics and patterning in plants. To do this, we develop mechanical models designed to include specific features of plant cell walls. LÄS MER
13. Pancreatic Growth and Secretion. An Experimental Study on Growth Factors in Rat and Mouse
Sammanfattning : The pancreas is a central organ in the digestion of food as well as in glucose metabolism. Its two major functions are exocrine and endocrine secretion. LÄS MER
14. Grain growth by Ordered Coalescence of crystallites in Ceramics : Grain Growth Mechanisms, Microstructure Evolution and Sintering
Sammanfattning : Grain growth and densification process play the two most crucial roles on the microstructure evolution and the achieved performances during sintering of ceramics. In this thesis, the grain growth of SrTiO3, BaTiO3-SrTiO3 solid solutions and Si3N4 ceramics during spark plasma sintering (SPS) were investigated by electron microscopy. LÄS MER
15. The Economics of Technology-Related Ownership Changes. A study of innovativeness and growth through acquisitions and spin-offs
Sammanfattning : The study reported in this thesis describes and analyzes technology-related acquisitions and spin-offs. The basic idea is that an economic system where large and small firms interact through technology-related ownership changes is highly conducive to overall innovativeness and long-term growth, given certain conditions.
