   Sammanfattning : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. LÄS MER

3. 12. Fluorescence Studies of Cell Division in Escherichia coli

   Författare :Bill Söderström; Gunnar von Heijne; Jie Xiao; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E. coli; Cell division; FtsZ; Fluorescence microscopy; FRAP; Biophysics; biofysik;

   Sammanfattning : In Escherichia coli the cell division is carried out by a large dynamic protein complex called the divisome. The divisome assembles in a two-step manner starting with the localization of the eukaryotic tubulin homologue FtsZ to the midcell. Together with other early arriving proteins FtsZ form an intermediate structure called the Z-ring. LÄS MER

4. 13. C1 Building Blocks: New Approaches for Thiomethylations and Esterification

   Författare :Marcus Söderström; Luke R. Odell; Anders Karlén; Vittorio Pace; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borontrifluoride; Dimethylsulfide; Thiomethylation; Methylthioethers; Dithioacetalation; Methyl-Dithioacetals; Friedel-Crafts; Diarylmethanes; Defluorination; Methyl-Dithioesters; Thioamides; Diazomethane; Esterification; Medicinal Chemistry; Läkemedelskemi; Medicinal Chemistry; Läkemedelskemi;

   Sammanfattning : The thioether motif is found in numerous pharmaceuticals. The simplest form of this motif, the methyl-thioether is similarly found in many biologically active compounds and has exhibited many advantageous properties. The installation of the thiomethyl moiety can be troublesome due to the toxicity and malodor of small sulfur reagents. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Titanium; surface modification; surface properties; plasma techniques; oxidation; surface spectroscopy; TiO2; biomaterials;

   Sammanfattning : The main theme of the present thesis is controlled preparation and characterization of oxidized titanium surfaces. Such surfaces are of general technological interest. LÄS MER

7. 15. From Tissue to Mutations : Genetic Profiling of Colorectal Cancer

   Författare :Lucy Mathot; Tobias Sjöblom; Mats Nilsson; Alberto Bardelli; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nucleic acid extraction; genotyping; targeted sequencing; mutation analysis; colorectal cancer; metastatic disease; Medical Science; Medicinsk vetenskap;

   Sammanfattning : Comprehensive characterisation of the mutational landscapes of solid tumours is a multistep process involving the collection of suitable samples, the extraction of nucleic acids and the preparation of these materials for mutational analyses. In this thesis, I aimed to develop a streamlined process for the analysis of colorectal cancer (CRC) patient samples in order to identify novel mutations that hallmark the development of advanced disease.
