In my degree project I have focused on how to make it easier for ambulance personnel to remove a motorcycle helmet after an accident. During my research I have interviewed ambulance personnel from different cities and a trauma surgeon to get a better understanding of how they work today and the problems they experience. Some of the problem areas are that you need a lot of force to remove the helmet, that the padding catches the ears and that the chin guard catches the face. Since ambulance personnel always assume that there is a neck injury after an accident, all these problems make it difficult to remove the helmet safely.The result is a motorcycle helmet with a focus on safe removal after an accident, to reduce the risk of worsening a neck injury. The solution suggested is that a small part of the back of the helmet is detachable, to make the opening larger.

Bakgrund: Från och med den 10 mars 2000 är det tillåtet för publika svenska börsföretag att handla i egna aktier. Det är intressant att belysa hur möjligheten att återköpa aktier uppfattas i Sverige. Syfte: Syftet med denna uppsats är att klargöra hur möjligheten att återköpa egna aktier påverkar ledningen och aktieägarna i ett aktiebolag. Genomförande: Vi har studerat artiklar och litteratur om ämnet återköp. Besöksintervjuer har genomförts på Assa Abloy, Electrolux, Investor, Skanska, Robur Kapitalförvaltning och Handelsbanken Markets.

Background and problem: Since the new law took place in 1999, it has been illegal towash a car with substances that can damage the environment on a paved street or on a driveway through a garage. This has conveyed to a new industry where more and more self-service car wash facility have opened around the country. Vetlanda Vägkrog AB has since 2012 been planning to install manual self-service car wash facility at the back of their restaurant business. The authors mission was to make an analysis in order to examine whether an investment of carwashes are lucrative enough for Vetlanda Vägkrog AB.Aim: The study's main objective was to analyze the profitability of an investment in a self-service car wash facility at Vetlanda Vägkrog AB, based on given data. The authors sub-aim was to clarify which factors in general that had played the greatest part in the establishment of a self-service car wash facility.Method: The authors have used an abductive approach in order to fulfill the aim of the study.

A great importance for the future of municipalize is the ability to attract and retain the younger part of the population.  For the Tärnaby area (a famous tourist resort for alpine skiing), a part of the Storuman municipality, this is a problem, and with a possible mining establishment job opportunities will be provided. In this study I have examined how young adults related to the Tärnaby area have reasoning about stay or move from the area and what may get them to move back.What is the area´s place identity and is it attractive for the respondents? Can a mining establishment change the negative population trend? The results showed that the respondent have a strong connection to the area and the identity of the place. A large proportion of the respondents indicated that they wanted to move back to the area of Tärnaby, if it was possible, due to work-related causes and social relations at existing place of residence. The respondents approach for a potential mining establishment is both of positive and negative sense.  However, a mining establishment is considered by the respondents to be of great importance for the future of the Tärnaby area..

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.

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Background: Low back pain (LBP) is a common disorder in the western world. A majority of those afflicted by a first acute episode is at high risk of developing sub-acute or persistent symptoms. Persistent LBP can be caused by pathological changes in the discs and disturbed neuromuscular activation, which can cause hypotrophy of the extensors strong type-2 muscle fibres. Deadlift (DL) is an exercise that may correct all these pathological transformations. Aim: To investigate the effect of DL-training on patients with persistent LBP.

The aim of the study is to investigate the relationship between text and picture in two works by Sven Nordqvist, with the focus on how the action is propelled. The two works are compared in order to bring out any differences in the relationship and what significance this can have for the interpretation. The study also considers the theory of conceptual worlds to examine how the books can promote pupils? literary understanding. The method of analysis is based on Rhedin?s (2001) theoretical concepts and elements of Nikolajeva?s (2000) terminology.

The canine population has during it?s time with humans gone through at least 2 major genetic bottlenecks, the first when it was separated from the wolf, and the second when it was divided into different breeds. Among other things, this has lead to the accumulation of unwanted genes, such as genes causing disease in dogs. One such inherited disease is syringomyelia, which has proven to be more common than expected, especially in certain smaller breeds such as the Cavalier King Charles Spaniel. Syringomyelia in dogs is often a secondary condition caused by the malformation called occipital hypoplasia.

The main focus of this study was to investigate how Swedish military veterans experience that events during an international service affect them after completed mission. This also includes the contact with their relatives. Secondly, this study deals with the course of the crisis, personal defense mechanisms, cumulative stress and post-traumatic stress syndrome (PTSD).The study was performed using a qualitative method and comprises individual interviews with six Swedish veterans. The responders were all men of different military positions, who participated in one or more international missions during 1993 to 2011.The results of this study show that, according to the veterans, the return back home is the most strenuous part of an international mission. With all the new experiences that an international service brings fresh in their memories, it is hard to re-adjust to the life of a civilian.In connection with the return back home, different degrees of stress reactions were also commonly seen, for example sleep disturbance, restlessness and exhaustion.

AbstractThe aim in this dissertation is to investigate into the working of the rehabilitation process as to actors involved. A specific focus has been set on the component ?Work introduction?. The study shows that the road back to work is a complex matter. Individuals involved have different backgrounds and living situations, which influence this rehabilitation.

Det är inte alltid företagen går med vinst utan det händer att ett beskattningsår slutar med en förlust. Lagstiftningen i Sverige och även internationellt tillåter företagen att spara denna förlust till ett år med vinst vilket resulterar i ett lägre skattemässigt resultat. I det fall flera beskattningsår slutar i förlust får de läggas till tidigare förluster och sparas ackumulerade för att rullas framåt på obestämt tid. Reglerna avseende förlustutjämning har funnits lagstadgat sedan 1960 och de resonemang som finns i föregående utredningar gäller i mycket fortfarande idag. Idag återfinns reglerna för denna förlustreglering, underskottsavdrag, i  Inkomstskattelagens (1999:1229) 40:e kapitel och har sedan införandet genomgått många förändringar i form av både förenklingar och spärrande lagstiftning.

Gender awareness is considered of absolute importance to Swedish school?s and preschool?s main mission ? equal opportunities for all children. Gender portrayal in childrens literature is now one subject of vast study, since literature often carry underlying messages of the perception of male and female. With this in mind, the purpose of this thesis was to analyse, mainly through Maria Nikolajeva?s scheme of gender ideal types, how the Swedish writer Per Gustavsson portrayed girls in four of his so called Prince- and princess books.
