Double-contrast MRI for the staging of rectal carcinoma: Technical aspects and clinical experience.
Popular Abstract in Swedish Cancer i tjock- och ändtarmen är idag den tredje vanligaste formen av till döden ledande cancer i världen. Den är vanligast i de högindustrialise-rade delarna av världen: Europa, Nord-Amerika och Australien. Prognosen för den enskilde patienten är helt beroende på cancerns utbredning vid diagnostillfället. Cancerns utbredning bedöms idag enligt olika indelningsprincipeAim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. The idea was that a rectally applied contrast medium causing distension and signal void of the rectal lumen and an intravenous inj

Resonant Tunneling in Laterally Confined Quantum Structures
In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. In addition, the thesis deals with the basic development of large-area double barrier resonant tunneling diodes, as a st
Rhythmic contrast between Swedish and Albanian as an explanation for L2-speech?
Based on observations of the rhythmic structure of L2-speech produced by L1-speakers of Albanian – which suggest the occurrence of transfer – a study is presented here that compares durational aspects between the two languages. In order to do this, speech read by Swedish and Albanian L1-speakers was recorded and investigated, and normalized durational factors were analysed. The results, however, d

RHR of building materials. Experiments with an OSU-apparatus using oxygen consumption
The Ohio State University rate of heat release apparatus was calibrated with two measurement systems, the standard compensated thermopile and an instrumentation for oxygen consumption measurements. Based on the calibration results the oxygen consumption technique was chosen when testing 13 different materials including wood-based materials, wallcoverings and plastics. The same set of materials has

A manual on ASIC front to back end design flow
This paper presents a manual that covers the necessary design steps for a basic ASIC design flow. It is shown how the manual writing process is organized such that each chapter covers a certain step in the design flow. The manual has been written especially with practicality in mind and has been successfully applied to undergraduate and postgraduate teaching

Growth rate and response of bacterial communities to pH in limed and ash treated forest soils
Culturable and total bacterial counts, bacterial growth rate and tolerance to pH, as well as microbial biomass, were studied in two coniferous forest soils. The pH had been changed by addition of lime and wood-ash from 4.3-4.4 to 7.0 in one soil and from 3.9-4.4 to 6.1 in the other. Higher total microbial activities and higher bacterial growth rates, measured as soil respiration rate and thymidine

Differential Optical Absorption Spectroscopy (DOAS) Measurements of Ozone in the 280--290 nm Wavelength Region
The differential absorption structure of the ozone spectrum between 250 and 330 nm has been investigated in order to determine the optimal wavelength region to be utilized for active differential optical absorption spectroscopy (DOAS) measurements. Considering aspects of atmospheric attenuation and interference from other species as well as the magnitude of the differential absorption cross sectio

The pedagogical dimension of internationalisation? – A challenging quality issue in higher education for the 21st century.
Abstract What are the pedagogical impacts of internationalisation on the development of higher education in Europe? How can we proceed in this process and take a pedagogical stance on the issue? This theoretical paper is partly based on a series of empirical studies conducted by the author, investigating students’ and teachers’ experiences and understanding of an internationalised educational cont

Analysis of Best High Rate Convolutional Codes for Faster than Nyquist Turbo Equalization
We find good rate 2/3 and 3/4 convolutional codes for use with iterative decoding (turbo equalization) of coded intersymbol interference with AWGN. The method is based on the input-output bit error rate characteristic of the convolutional BCJR decoder module. An analysis leads to an equivalent minimum distance under the required intrinsic subtraction, which depends on free distance and an input-ou

Immuno-affinity interactions in sample preparation and analysis
Immuno-affinity interactions (antibody-antigen) belong, together with enzyme-inhibitor/substrate/coenzyme; oligosaccharide-lectin; DNA/RNA-protein interactions etc, to the class of bio-recognition. Immuno-affinity is widely used for analysis in immunoassays with numerous applications in a variety fields (i.e. environment, foodstuffs, clinical, pharmaceutical, diagnosis, etc.). Recently, the immuno
Appropriations of Shakespeare's King Lear in Three Modern North American Novels
This thesis examines the creative appropriation of Shakespeare in theory and practice. It is based on close readings of King Lear alongside three appropriations of the play in works of fiction by three North American women writers: Jane Smiley, Anne Tyler, and Margaret Atwood. The aim is to demonstrate how a ‘palimpsestic’ reading, i.e. a reading in which the reader oscillates between ‘pre-text’ a
