1. 11. Tracking Chambers with Two-Dimensional Readout used for Extraction of Particle Production Ratios in High Multiplicity Pb+Pb Collisions at 158 A GeV

   Författare :Tomas Svensson; Fysiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; position resolution; wire chamber pixel readout; pad readout; tracking; multi-step avalanche chamber; Fysik; Physics; particle ratios;

   Sammanfattning : Heavy-ion collisions at high energies calls for new technical solutions to cope with the very high multiplicities of produced particles. In this thesis the design and development of two types of tracking chambers for high multiplicity environments are presented. LÄS MER

   Sammanfattning : Today, assessment of the health of coastal waters is recognized as being important for both the conservation of nature and well-being of humans. Anthropogenic pollution has been the focus of extensive research for some time and a variety of programs for the monitoring and assessment of environmental pollution have been developed. LÄS MER

4. 13. Some new Fourier multiplier results of Lizorkin and Hörmander types

   Författare :Lyazzat Sarybekova; Michael L. Goldman; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fourier multipliers; Lizorkin theorem; Hörmander theorem; regular system; Mathematics; Matematik; Mathematics; Matematik;

   Sammanfattning : This PhD Thesis is devoted to the study of Fourier series and Fourier transform multipliers and it contains four papers (papers A - D) together with an introduction, which put these papers into a general frame. This extensive introduction can also be seen as an independent description of this important area including the historical development and the most important results. LÄS MER

5. 14. Integral inequalities of Hardy and Friedrichs types with applications to homogenization theory

   Författare :Yulia Koroleva; Andrey Piatniski; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

   Sammanfattning : This PhD thesis deals with some new integral inequalities of Hardy and Friedrichs types in domains with microinhomogeneous structure in a neighborhood of the boundary. The thesis consists of six papers (Paper A -- Paper F) and an introduction, which put these papers into a more general frame and which also serves as an overview of this interesting field of mathematics.

7. 15. Cancer proteomics : characterisation of protein expression in human epithelial tumours

   Författare :Ayodele A Alaiya; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Two-dimensional gel electrophoresis; protein expression; mass spectrometry; epithelial tumour; heterogeneity;

   Sammanfattning : Defining differences in protein expression between tumour cells of various degrees of malignancy is a first step in the development of markers for tumour diagnosis. In this thesis, the expression of multiple proteins in benign and malignant human ovarian, breast and prostate tumours was examined using two-dimensional gel electrophoresis (2-DE). LÄS MER
