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

In this work, a numerical study has been performed to simulate the heat transfer and fluid flow in a transonic high-pressure turbine stator vane passage. Four turbulence models (the Spalart-Allmaras model, the low-Reynolds-number realizable k-ε model, the shear-stress transport (SST) k-ω model and the v²-f model) are used in order to assess the capability of the models to predict the he

The problem of correctly recovering assembly instructions from a binary has received much attention and both malware and license validation code often relies on various anti-disassembly techniques in order to complicate analysis. One well-known anti-disassembly technique is to use overlapping code such that the disassembler starts decoding from an incorrect byte, but still recovers valid code. The

We present a novel method for tracing reflected reading and multimodal learning, based on a combination of eye tracking and cued retrospective verbal protocols. With the help of this method, we can trace pupils’ problem solving, their integration of text, pictures and graphics, connect the process of reflected reading to the product (scores, learning outcomes) and uncover pupils' reading strategie

In the last decades, the growing competitiveness of the market has continuously driven the forming companies to highly optimize their products regarding offered performance at minimum cost. In order to achieve better products, studies where conducted with different material models when simulating the forming process of titanium. The material is often used in heat exchanger applications. Titanium h

In this Licentiate Dissertation presents a new model for selecting environmental performance indicators in order to improve environmental management. The suggested Total Cost Indicators support a support a preventive approach to environmental management, where environmental issues are addressed before they arise - and before they become costs. The method of selecting indicators builds on earlie

Vehicles in the future are anticipated to have the ability to communicate and exchange useful information in order to avoid collisions. However, for this cooperation to be possible all vehicles will have to be equipped with compatible wireless IEEE 802.11p modules that implement intelligent transport systems operating in the 5 GHz frequency band standard (ITS-G5 or WAVE). During the implementation

Climate change and disasters are among today’s most pressing issues. The damage caused by the world-wide increase in disasters is staggering, with the urban poor being most at risk. Disasters make their al-ready precarious living conditions worse, creating a vicious circle of poverty. More and more attention has thus been given to the need to address changing climatic conditions and disaster risk

This article was given as a paper at the conference on Deification/Theosis at Drew University, Madison, N.J. in May 2004. The article adresses the growing interest in deification/theosis in contemporary Western theology. Recent research on deification/theosis in Luther and Thomas Aquinas are critically evaluated. The article ends with a proposal. For the better understanding of similarities and di

The concepts of ‘transparency’ and ‘evidence of what works’ are key features in the implementation and success of the open public service policy. This paper explores, from the perspective of the third sector, the meaning of these concepts and how we can expect them to be operationalized. Initially, an implementation guided by evidence and transparency seems reasonable and ethical. The practical me

Carrier frequency offset (CFO) synchronization is a crucial issue in the implementation of orthogonal frequency division multiplexing (OFDM) systems. Since current technology tends to implement different standards in the same wireless device, a common frequency synchronization structure is desirable. Knowledge of the physical frame and performance and cost system requirements are needed to choose

This paper introduces a two-dimensional extension of the well established Rietveld refinement method for modeling neutron time-of-flight powder diffraction data. The novel approach takes into account the variation of two parameters, diffraction angle 2θ and wavelength λ, to optimally adapt to the varying resolution function in diffraction experiments. By doing so, the refinement against angular- a
