A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.

Elite sport is becoming more professional, and elite athletes have to be more committed to spend several hours in training to achieve elite level and this means that the time to pursue a university academic career to the side of elite sport is minimized. Still only few elite athletes will be able to make a living of their sport. The objective of this study is to gain a better understanding of the opportunities and difficulties for a student who combines academic study with elite sport. Data was collected through semi-structured interviews with eight students studying at the University of Umeå, combining elite sport with academic studies. Results show that there are high demands on elite students to structure and plan for the combination of studies and elite sport.

The purpose of this paper is to provide an overview of how cooperation functions between the health services and social services within Sollentuna County Municipal area regarding clients and simultaneous or double diagnoses. Focusing more specifically; the paper also aims to provide additionally, an inquiry as to how the implementation of the Gemensam Individuell Vårdplan (GIVP) (The Integrated Individual Service Care Programme or (GIVP) functions within the Sollentuna Municipal County Area. The questions asked in the paper are: How do the Municipal and County Council personnel experience how the (GIVP) system functions in Sollentuna? How do the Municipal Council and County Council personnel respectively describe their own and their cooperative sister services rolls in terms of the implementation of the GIVP system in practice? The projection activates a hypothesis and tries to explain how the cooperation functions and provides an assessment as to how it functions or not as may be the case in practise. The authors attempt to achieve this using a combination of methodologies.

Background: The majority of the occupational accidents and work-related diseases at Swedish workplaces occur due to poor ergonomics during lifts and transportation of objects. The most common consequence of poor ergonomic conditions is low back pain (LBP) and the risk of developing LBP increases as the mechanical loading on the intervertebral disks grows. This study has investigated the biomechanical loading in the low back during two different types of patient lifts. The first lift (lift A) is developed by Modern Arbetsteknik (MA) and the second lift (lift B) is a common lifting technique among care workers. Objectives: The aim of the study was to identify any advantages or disadvantages with MA?s lift, regarding shear and compression forces in the L5/S1 disc.

Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical. The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank. The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data. The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.

The tribo system ice-curling stone was investigated in order to understand the mechanisms behind the stones' behavior on the ice sheet. The problem with non-identical stones should also be addressed.The stone curls, that is, its sliding path deviates from a straight line to the right for a clock-wise rotation and to the left for a anti-clock-wise rotation. Several mechanisms to explain this behavior have been proposed over the years but none has been successful.By carrying out experiments at the local curling rink and studying silicon castings of ice- and stone-surfaces with scanning electron microscopy and vertical scanning interferometry, it has been decided that the curl is not due to dry friction, ice-debris or the difference in friction on the left and right side of the stone. The side force comes from the fact that the friction is higher at the back of the stone than at the front.The contact between stone and ice is never completely dry, nor in the hydrodynamic lubrication regime. It is probably a combination of hydrodynamic lubrication and a contribution from mechanical scratching of the ice.

The aim of this study was to investigate the effects of an infusion of hypertonic saline solution (HSS) in combination with an oral waterload on cows suffering from rightsided displacement of the abomasum (RDA). Six dairy cows were treated with 7,2% HSS in a dosis of 5 ml per kg bodyweight. They also received an oral waterload of approximately 15 liters. To monitor changes in fluid-, acid-base- and electrolyte-balance, bloodsamples were collected during the next 24 hours. During this period, the cows also underwent surgery to empty and correct the position of the abomasum.

The purpose of this study was to describe and analyze youth community service in the Kalmar municipality. Our focus was on juvenile offenders and predecessor of public authorities. The juvenile offenders in our study have completed youth community service. A qualitative study was undertaken which include seven interviews. Our empirical data were compared and analyzed with previous research data.

Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.

Breaking through the clutter and getting consumers? attention is a constant battle for marketers. Could consumer magazines be the solution to the problem? It is not a new marketing method but consumer magazines do not look like traditional marketing and they offer consumers value. Since these are qualities that could increase consumers? will to take part of commercial messages, it might be a method that deserves more attention.
