Motivationen med studien var den alldeles för höga stråldosen som används vid CTundersökningar. I de allra flesta fallen anpassas man inte rörströmmen efter patientens storlek och därmed får smalare patienter en onödigt hög stråldos. Målet var att reducera stråldosen till patienter som undersöks med datortomografi utan att minska på bildkvalité, genom att anpassa rörströmmen efter patientens stoIn this study we have investigated the possibilities of dose reduction in CT at a constant level of image quality by adjustment of the tube current to the phantom size. The motivation with the study is the high radiation doses to the patients and the increasing frequency of CT examinations and the variety of examinations in CT, and that the same tube current is used for different patient sizes. Ac

In this thesis, the question of how to balance the right to reindeer herding against competing interests of land use in Sápmi in accordance with the indigenous rights of the Sami, will be examined. In order to answer this question other questions needs to be answered – What is the right to reindeer herding? Who is the holder of the right? Where can the right be exercised and finally, how can the r

A very important aspect of the employees duty to the employer is to be loyal. The conflict between the freedom of speech and the employees loyalty duty is not new. However electronic trace like social media bring employees the possibility to present critics, disapproval and sometimes incorrect information to a large public. On the other hand the new technic also brings new possibilities to save th

We study an extended bootstrap percolation process in several steps in dimension one, assuming noncyclic boundary conditions. We study the asymptotic behavior of the process as the size of the underlying graph goes to innity. We nd a phase transition with respect to the initial conditions. The phase diagram on the set of initial conditionals of the extended process is described completely. This pr

This essay will summarize and study existing theories and the recent developments regarding long-term incentive (LTI) plans in Swedish companies listed on Nasdaq OMX Stockholm. The underlying theory is the principal-agent problem that arises in public companies, which highlights the behavioural aspects of decision-making for employees in a managerial position. This study aims to provide evidence t

The European Union is a large organ that is constantly under reformation. EU and the Common Agricultural Policy has during its lifetime gone through several major reforms in order to adjust regulations for certain markets. Our study will pay focus on the Sugar reform that was implemented in year 2006 and what effects it had on the European sugar market. The purpose of the reform was to give more p

Urban mobility as we know it is changing. On the one hand, challenges persist ranging from climate change, increasing urbanization and demographic change. On the other hand, recent technological advances enable novel approaches to mobility altogether. This paper investigates Personal Rapid Transit (PRT) as one such innovative mobility form in the context of the changing urban mobility paradigm. Du

ABSTRACTThis study aims to explore the scope of ‘knowledge-carrying’ objects in learning situations. The study is based on a qualitative content analysis of a design project conducted in a science centre for children aged 7-10 years, learning about polymers and circularity. The design project is based on research through design and has been an iterative process where design experiments and observaThis study aims to explore the scope of ‘knowledge-carrying’ objects in learning situations.

To study adhesion in flexible laminates, standardised peel tests are commonly used where macroscopic measurements, e.g. peel force versus peel arm displacement, are extracted. However, insights into the adhesion mechanisms at the microscopic scale are limited. This study has developed a framework for determining peel arm geometry parameter evolution and deformation in packaging material laminates.

Sweden is often regarded as one of the most progressive countries in terms of legislation and policies protecting the rights of lesbian, gay, bisexual, trans, and queer (LGBTQ) people. Such measures aim to promote wellbeing among LGBTQ individuals, who generally report more negative experiences compared to heterosexual cisgender people. Swedish legislation requires employers to take active measure

Our beliefs and opinions are shaped by others, making our social networks crucial in determining what we believe to be true. Sometimes this is for the good because our peers help us form a more accurate opinion. Sometimes it is for the worse because we are led astray. In this context, we address via agent-based computer simulations the extent to which patterns of connectivity within our social netOur beliefs and opinions are shaped by others, making our social networks crucial in determining what we believe to be true.

This article deals with narratives of rape in Swedish newspapers between 1990 and 2015. Though perpetuating myths and stereotypes about rape, rapists and rape victims, the main argument is that the narratives of rape in the news are diverse. This diversity is analysed in terms of different genres—narratives of “the lonely pervert”; “the sex slavery rape”; “the celebrity rape”; and “the suburb rape

As pharmaceutical removal was not part of the of the modern wastewater treatment plant (WWTP) design, it is not surprising that WWTPs have been identified as major point sources of pharmaceuticals entering the environment. The oxidation of pharmaceuticals in the WWTP effluent is one of the-end-of-pipe solutions that are considered most ready for full-scale use. However, there are several aspects oAs pharmaceutical removal was not part of the of the modern wastewater treatment plant (WWTP) design, it is not surprising that WWTPs have been identified as major point sources of pharmaceuticals entering the environment.

Factors influencing the effect of pilot-injection on main-injection combustion were investigated using heat release analysis in a heavy-duty diesel engine fuelled with standard diesel fuel, and included the effect of those factors on engine performance and emissions.Combinations of pilot injection parameters i.e. pilot start of injection, pilot mass, pilot-main injection separation, and rail press

Ashbya gossypii is a homothallic, flavinogenic, filamentous ascomycete that starts overproduction of riboflavin and fragments its mycelium quantitatively into spore producing sporangia at the end of a growth phase. Mating is not required for sporulation and the standard homothallic laboratory strain is a MATa strain. Here we show that ectopic expression of Saccharomyces cerevisiae MATα2 in A. gossAshbya gossypii is a homothallic, flavinogenic, filamentous ascomycete that starts overproduction of riboflavin and fragments its mycelium quantitatively into spore producing sporangia at the end of a growth phase.

Purpose: The purpose of this paper is to contribute to a better understanding of the occurrence of strategic error in using key performance indicators (KPIs) in innovation Design/methodology/approach: This case study was conducted at the innovation department of an organization in the process industry that operates production sites and sales organisations worldwide. Observations and interviews werTo date, measuring innovation has not been an exact science. As in many areas of organizational life, errors in measuring innovation are a recurring fact. Innovation researchers and practitioners alike have become increasingly interested in understanding the occurrence of organizational errors and how these errors affect innovation and its measurement. This empirical study aims to address this und

Thrombotic microangiopathy can be caused by several conditions which are difficult to diagnose from the clinical presentation alone. Deficient enzyme activity of a newly-discovered enzyme, ADAMTS-13, can lead to thrombotic thrombocytopenic purpura (TTP). Lack of ADAMTS-13 activity causes increased concentrations of high molecular weight von Willebrand factor forms and increased platelet aggregatio
