The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .

BakgrundAkut appendicit är en av de vanligaste akuta buksjukdomarna i västvärlden och cirka 10 000 människor i Sverige drabbas varje år. Diagnosen ställs i första hand med klinisk undersökning men om den kliniska undersökningen är osäker kan radiologiska metoder som ultraljud, datortomografi (CT, computed tomography) och magnetisk resonanstomografi (MR) vara till hjälp. SyfteAtt jämföra sensitivitet och specificitet samt att beskriva fördelar och nackdelar med undersökningsmetoderna ultraljud och CT vid frågeställningen akut appendicit. MetodEn litteraturstudie gjord på tretton vetenskapliga artiklar sökta i Pubmed med sökord som bl.a. appenditicits/ultrasonography, computed tomography och acute appendicits. ResultatSensitiviteten och specificiteten för CT varierade mellan 76- 100 % respektive 69-100 % och för ultraljud mellan 59- 92,7 % och 78-100 %. Fördelar med CT är bl.a. att appendix bättre kan lokaliseras, bättre träffsäkerhet samt att den kan ställa alternativa diagnoser och reducera antalet negativa appendektomier.

AimThe aim of this study was to evaluate the effects of MotVikt´s obesity-treatment program on eight severely obese subjects, concerning Body Mass Index, Waist-Circumference and Weight after three and a half months and Sense of Coherence, Body Image and Self-experienced Health after three months. The question in focus was: Did MotVikt´s obesity-treatment program have any effects concerning the factors mentioned above?MetodInformation was collected with questionnaires that were filled out by the eight subjects, three men and five women, who participated in MotVikt´s last round of treatment. Data concerning waist-circumference, weight and BMI were provided by MotVikt. The questionnaires that were used to get information about Sense of Coherence, Body Image and Self-Experienced health were SOC-29, BSQ and IQOLA SF-36.ResultatThe average BMI in the group has decreased with 2,9 kg/m2, from 39,7 till 36,8.

AbstractAll headmasters want to lead teachers so that the students will achieve their own goals as well as the goals of the education. The salutogenic leadership is a way to lead in the right direction. This type of leadership depends on Antonovski?s (2005) theory of Sense of coherence. The theory of Sense of coherence is built on the concepts of comprehensibility, manageability and meaningfulness.

The aim of this study is to examine which factors in the receiving-country that have had an influence on three now adult unaccompanied refugee children. The method used in the study is qualitative interviews with the three above-mentioned participants. The results show that some factors are perceived as helpful, having a positive influence on the participants life while other factors are perceived as worsening, having a negative influence on their life. Depending on the context some factors such as age, the Swedish language and housing arrangements have had both positive and negative influences on their life. Positive factors are among other things: access to good treatment and support, help with processing trauma and bad mental health, help with understanding coherence, access to a social network, family reunification, resilience and other internal factors.

Mitt arbete handlar om mötet mellan rysk konstruktivism och science fiction. Detta har jag gestaltat i ett textilt rum inspirerad av science fictionkarraktären Doktorn ur Doctor Who. Doktorn är en utomjording av en långt mer utvecklad art och från en mer avancerad civilisation än människorna, som reser i tid och rum i sitt tids-och rymdskepp TARDIS. Jag har designat ett rum som är min textila tolkning av TARDIS innersta. Arbetet kretsar kring tankar om gestaltning av en flerdimensionalitet som bara kan anas, inte ses eller förstås.

This qualitative study examines if an interest in soccer can give the same meaningfulexperiences in a person's life as a religion would. Five soccer fans were interviewedregarding the meanings and impact of soccer in their lives. Two theories in the fields ofsport and religion were used to analyze the data: Antonovsky's sense of coherence (SOC)with its components meaningfulness, manageability and comprehensibility and Heelasand Woodheads "life-as" and "the subjective-life? derived from the concept "thesubjective turn". It was concluded that the interest in soccer affected the respondents?views of life.The respondents? personal identities were strongly associated with groupmembership, meaning that their interest in common with others was perceived to makeeveryday life meaningful and manageable.

One purpose of our study was to investigate if equality in work time and parental leave in a relationship affect the time that parents spend with their children. Our first hypothesis was that increased equality in work time and parental leave leads to a reduction of the parents? total time with their children, ie the children spend more hours in pre-school and begin pre-school earlier. In order to test our hypothesis, we investigated the relationship between the woman?s and the man?s work time and parental leave and the time that the children spend in pre-school as well as at what age they began pre-school by using two surveys.Our study showed a significant coherence between both working women?s work time and the children?s time in pre-school as well as women?s parental leave and the children?s age at start in pre-school.

The aim of this qualitative study was to get a deeper understanding of social workers experience that children who participate in the Trappan-insatsen get a sense of coherence. To achieve an empirical material social workers who perform Trappan-samtal have been interviewed. The study shows that it is important that children get help and support to talk about the trauma they experienced. The support of the narrative, however, differ depending on the child's age, it is important to have a flexible approach as a Trappan-user. It appears that it is essential that parents give their consent to the children so they can talk about the violence.

The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.

The aim of this study was to examine the relations between sense of coherence (SOC), perceived social support and mood, the study also included gender and civil status in the analysis. In the analysis mood was the dependent variable. The study included 81 respondents, all students from Växjö university, who answered a survey with three parts: SOC 13, Mood Adjective Checklist (MACL), and an own constructed instrument that measured perceived social support. The result showed that those with a high SOC tended to have a greater mood. High scores on perceived social support also were related to a greater mood.

The aim of my study was to investigate a few young peoples experience of their treatment. The study was qualitative based on interviews with three young persons at the end of their treatment there. The subject was chosen because this kind of youth housing is an interesting alternative to institutional care for young people, despite there is not much known about the results of the treatment. The results were analyzed from earlier research and central concepts from the theory of empowerment and Anton Antonovskys theory about Sense of coherence. The results of this study show that these young peoples are satisfied with their treatment at the youth housing.

The purpose of this study was to investigate and expand the knowledge of how bereaved spouses in palliative care handled their grief. Attempts were also made to distinguish common patterns among the experiences that the bereaved spouses expressed.  Furthermore the study aimed to understand how the bereaved spouses handled their grief, and to understand what helped them to move on. A qualitative method was used in this essay, related to the purpose of investigating the spouses? emotional experiences. The questions used to reach an understanding of the matter were: How did the bereaved experienced their grief? Were there important contributing factors worsening their grief or making it easier? How did the bereaved persons handle their grief, and what helped them to work things through and carry on with their lives? The result was analyzed by using Antonovsky?s theory; a feeling of coherence, Lazarus? coping theory combined with Folkman?s revised coping theory.

Tekniken inom datortomografin har utvecklats explosionsartat främst det senaste decenniet från att år 1993 erhålla 2 samtidiga snitt per rotation runt patienten, till år 2008 erhålla 64 samtidiga snitt per rotation. Utvecklingens största utmaning har varit att begränsa stråldosen till patienten så pass att de erhållna bilderna är av tillräcklig kvalité så att en rättvis diagnos kan fastställas. Trots ett ständigt arbete med att reducera stråldosen inom datortomografins multisnitt teknik kommer det alltid att finnas fysiska principer som påverkar dosökningen jämfört med singelsnitt tekniken. Däremot kan röntgensjuksköterskan påverka stråldosen till patienten avsevärt genom att jobba utifrån viktiga begrepp. Syftet med detta arbete är att beskriva utvecklingen från singelsnitt till multisnitt tekniken och vad detta fört med sig i aspekter som stråldos och bildkvalité.
