Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.

Clarice Lispectors is one of Latin Americas most famous writers, and she wrote a number of books during her lifetime. Her novel Stream of Life (Água viva), which came out in 1973 and was translated into Swedish in 2007, is considered to be one of Lispectors most difficult texts to read. It consists of several fragments put together into one text; however the text has no traditional narrative or structure. It is the flow of moments that moves the text forward, as it is written down by the protagonist in the book.The primary aim of this essay is to examine how the protagonist in Stream of Life through different means, as the moment, the description, the word and the variations, creates an active participation in the formation of its identity. I will discuss the moment and its act of constructing the book?s circular structure, which is of importance.

The purpose of this study was to describe how patients with hemodialysis experience their dialysis treatment. The study was conducted as a qualitative descriptive design. The study is based on six interviews. The interviews were transcribed in their entirety and analyzed according to content analysis inspired by Granheim and Lundman.

Then the interviews were analysed with a phenomenological attempt with the intention to create at picture of the girls? world. The result of the interviews presents from the interviwguides area and interpret towards the background of earlier research that present in this study.

The last decades the increased computerisation at the places of work has led to new physical loads in the working life and new demands on the working environment. The widespread usage of computers in the working life has led to more sedentary work and less daily movement.The purpose of the thesis is to develop a new product to a concept that in a low intensive and healthy promotional way will activate the body. The product will make a combination of healthy promotion activity and work during office hours possible and primary aims to those with a sedentary office work, which leads to that the body don´t get to be activated in the extent needed.Information has been gathered from studies already made in this area, interviews plus a study and an experiment. From the gathered information concepts and functional solutions has been generated and evaluated to result in a product concept.The thesis has resulted in a concept that consists of a work place unit where the user walks on a treadmill and works at the same time.A general conclusion which can be drawn is that the majority of persons that tested to walk and simultaneously work with a computor on the treadmill found this way of working attractive. Many were positively surprised and said that they would use such an physically activating work place implement if it was available at their place of work..
