Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications. The purpose of this work was (1) to understand the basics of the Monte Carlo simulation software Geant4 Application for Tomographic Emission (GATE); (2) to create a model of Philips Gemini TF PET/CT system; (3) to run a number of simulations to comp

Detta arbete handlar om att utveckla och förbättra en försöksuppställning som kan mäta laserinducerad fosforescens både spektralt och tidsupplöst. Ämnet som emitterar fosforescensen befinner sig i en kalibreringsugn som kan värmas till olika temperaturer vilket möjliggör studier av irreversibla åldringsprocesser i ämnet som funktion av temperatur och tid. Fosforescens är den långa efterglöd som fo

During the last two decades a new administrative level between municipality and national has occurred, most referred as regions. Regions should work as a tool for intergrading and achieve growth in the concept of sustainable development (economic, social and environmental sustainable) in a specific area. In order to attain this and to integrate a whole region, even the areas in the periphery, it

Based on an explorative case study approach, this thesis investigated whether the Uppsala model functioned in Samsung Electronics Corp. (SEC) case. The purpose of this study was to upgrade the Uppsala model by using a representative case of SEC. This thesis found that there are two dimensions derived from the Uppsala model. The first dimension is the sequential nature of the internationalization p

Populärvetenskaplig sammanfattning: Undersökningen baseras på prover ifrån borrkärnor som tagits från sandstenar vilka avsattes för ca 200 miljoner år sedan. Vid denna tid var hela nordvästra delen av Skåne täckt av ett stort delta med en avsättningsmiljö som gav sandstenar med ett stort innehåll av ler. Ler deponerades då det rådde lugna vattenmiljöförhållanden, såsom vid olika årstidsvariationerAn examination of permeability differences was made on plugs obtained from six drill cores in both horizontal and vertical directions, representing different facies of the Hettangian strata from the Höganäs Formation. The permeability analyses distinguish permeability differences from anisotropy and an index was created to evaluate the anisotropy. The cause of the measured anisotropy in this study

Populärvetenskaplig sammanfattning: Den afrikanska kontinentplattan bildades då flera äldre plattor kolliderade. Namibia ligger i skarven mellan två sådana gamla kontinentplattor där södra Namibia tillhör Kalahariplattan och norra Namibia tillhör Kongoplattan. Mellan dessa två plattor löper ett brett bälte, det så kallade Damarabältet. Detta bälte var före kollisionen mellan plattorna ett sund därThe Mon Repos covers an area of approximately 10 x 4 km. It consists of a zoned intrusion, where the peripheral parts are monzodioritic and the central areas granitic. Mon Repos is situated in central Namibia approximately 150 km northwest of Windhoek. The area is a part of the Pan-African Damara Belt, which extends from the coast northwestwards through central Namibia. Mon Repos has been dated to

This thesis investigated the effects of word accent mismatch on the processing of word accents in Swedish. It was found that Accent 2 is more strongly associated with suffixes in the mental lexicon as compared to Accent 1.

"Executive summary The tourism sector is today the largest business sector in the world, employing over 230 million people. It has been growing incessantly the last decades and shows no tendencies to slow down. Tourism can bring strong economic support to a developing country, but has also been pointed out as a major contributor to climate change as well as environmental degradation and poll

More and more corporations around the world is starting to work in project form and leaving their traditional function based way of organising themselves behind. This leads to new ways of driving and implementing changes and improvements. It requires another approach and this approach has to deal with the individual employee in a greater extend. Alfa Laval often questions how to make a project to

It is commonly assumed that the speech production process is started and guided by a clear conception of what to say, i.e. an intention or a pre-linguistic message. This intention can also function as a standard of accuracy against which actual performance can be measured. But critique against the idea of such a centrally governed process has been offered, and propositions for how a distributed mo

The purpose of this study is to provide a theoretical framework that can be applied to both religious and secular terrorism. It is suggested that terrorism can be divided into two categories; practical and ideological. The first category, terrorists with practical objectives like sovereignty or end to repression, are generated by local conflicts. These local conflicts can also have a global impact

There has been considerable scepticism in Europe over the reliability of Russia as a secure source of energy for the EU. Despite Russia and EU being economically interdependent with regard to energy and other trade, there is still concern over potential supply disruptions. What can be gathered from media and scholarly sources is that Russia is potentially an unreliable supplier yet it is currently
