1. Amine Transaminases in Multi-Step One-Pot Reactions
Sammanfattning : Amine transaminases are enzymes that catalyze the mild and selective formation of primary amines, which are useful building blocks for biologically active compounds and natural products. In order to make the production of these kinds of compounds more efficient from both a practical and an environmental point of view, amine transaminases were incorporated into multi-step one-pot reactions.

2. System Identification with Multi-Step Least-Squares Methods
Sammanfattning : The purpose of system identification is to build mathematical models for dynam-ical systems from experimental data. With the current increase in complexity of engineering systems, an important challenge is to develop accurate and computa-tionally simple algorithms, which can be applied in a large variety of settings.

3. Modeling of dielectrophoresis in micro and nano systems
Sammanfattning : This thesis presents models and simulations of dielectrophoretic separation of micro and nano particles. The fluid dynamics involved and the dielectric properties of water inside single-walled carbon nanotube are studied as well. LÄS MER
4. Modeling of multi-step oral carcinogenesis in vitro : assessment of growth, differentiation and apoptosis markers
Sammanfattning : Human oral mucosa, especially the buccal epithelium, is worldwide a common site for cancer. Cancer development frequently results in inactivation of tumor suppressor p53, a central regulator of growth and programmed cell death, and deregulated expression of structural elements like cytokeratins.

5. Multicomponent Catalytic Reactions : Theoretical and Experimental Studies
Sammanfattning : In this thesis, Density Functional Theory (DFT) methods have been applied to study the mechanisms of three different multicomponent organic reactions. Also, a new synthetic procedure for the preparation of quinolinium salts is presented, and its mechanism also studied by DFT calculations. LÄS MER
