Utrustning för automatmontering av ackumulator
This report deals with an exam report written by Olle Hjalmarsson and Thomas Likar, students at Högskolan i Halmstad. The project was carried out for Haldex Traction AB in Landskrona whose business consist of manufacturing automatic all wheel drive systems (AWD-system). These systems consist of a plate clutch which activates all four wheels of a 4-wheel driven vehicle. An important component in these clutches is the accumulator which basically consists of a piston under the load of a spring which creates an oil pressure with the help of an electric motor used for actuating the clutch.At Haldex difficulties has been experienced regarding the assembly of the accumulator parts due to the small tolerances between the piston and the hole of the accumulator in the cast aluminium housing. Attempts have been made to assemble the parts in existing robot cells.
Tillverkning av mikronålar för medicinsk tillämpning
Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.
Att berätta en relation. En etisk läsning av Emilia Fogelklous "Arnold"
The subject of this dissertation is the autobiographical novel Arnold by the Swedish writer Emilia Fogelklou (1878-1972). By combining Gérard Genette?s narratology and Andrew Gibson?s narrative ethics this study seeks to examine through what means the relationship is being told and with what ethical consequences different strategies are used to tell one?s experiences from life. The narrative analysis focuses on how the narrator is engaged in the narrative, how the bond between narrator and characters can be described, what is known to whom and how, and what is beyond the narrative?s limits.
Kunskap på olika nivåer. Kunskapsförmedlingen mellan kockstudent och lärare på olika utbildningsnivåer
AimThe aim of this study has been to examine how health enhancement teachers in Montana, USA, view the value of physical activity from a lifelong perspective.In what way does the health enhancement teacher think the importance of physical activity from a lifelong perspective could be presented?What resources are available for teachers to present the value of physical activity from a lifelong perspective?MethodThe issue has been answered through qualitative interviews consisting of six health enhancement teachers, four women and two men, in Montana, USA. One of the teachers worked at an elementary school (for 30 years), three teachers worked at middle schools (20, 10 and 8 years of work experience) and two of the teachers interviewed worked at a high school (30 and 3 years). ResultsThe majority of teachers feel that a wide variety of activities, adapted to an individual level, and the understanding of a healthy lifestyle are important in order for the teacher to present the value of physical activity from a lifelong perspective.The teachers felt they had sufficient material in order to present the value of physical activity, where the school budget provided the teachers with materials every year. In addition to the budget, all the teachers had 12 hours of professional development every year where they could attend conferences or their own choice of professional development.ConclusionWith the help in forms of professional development offered by the school, conferences, meeting with other teachers, and their own choice of development, the teachers instruction techniques could increase which could help the teachers to find the pupils? interest for different kinds of physical activities.KeywordsPhysical education and health, physical activity, SOC, sense of coherence..
Kartläggning och visualisering av riggkonstruktionsprocessen : Fallstudie från Scania
Mapping a process enables a greater understanding of the work, and is standard to evaluate and improve a process. This thesis is conducted at Test Bed Mechanical Design at Scania in Södertälje. Test Bed Construction is a complex process, characterized by a large amount of creative work, technical challenges and coordination between different people and different organizational functions.The aim of the thesis was to identify the Test Bed Construction Process and to develop a visual model of the workflow that also served as support for the engineers in their daily work. During the mapping process, comparisons were made with previous research in lean product development to identify process improvement.A literature review on process mapping and process visualisation resulted in a method for process mapping. The study showed that research on process visualisation is neither structured nor well defined.
Downward migration and transfer to plants of radiocaesium in Scottish soil profiles : a comparison with earlier studies
Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.
Impleamini agnicione voluntatis Dei : En predikan ur Skoklosterhandskriften
This essay describes my work as a director in a specialized orientation within psychodrama, surrealistic psychodrama. Using the language and performance techniques of theater and under the guidance of a director, psychodrama creates an improvised narrative or story. The essay describes several dramas I have directed, reflecting on my actions and choices as a director and group leader. I examine whether my working method has allowed me to be spontaneous and creative, which I believe the example of "The dangerous bear" demonstrates. The process enabled me to establish trust and receptivity so that a newly constituted group dared to investigate conflicts in symbolic ways associated with illness and death.
Effektivisering av en administrativ process
For a long time Lean has been a well-known concept among manufacturers. Theinterest of understanding Lean and the ability to implement it is common amongcompanies. The concept of Lean, used in the right way, can help companies to reducetheir lead times, their complexity and increase the efficiency of the working processes(Hyer och Wemmerlöv, 2002). Unfortunately the work towards increased efficiencyhas primarily been focused on manufacturing and plant work, resulting in that Leanhas been adjusted to these areas. The conclusion of this is that companies don´tprioritize to improve processes such as administrative ones.

AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.
Jämförande studie av normal ERG-svar hos tre olika hundraser :
The purpose of this study was to compare normal electroretinographies (ERGs) from three different canine breeds in order to evaluate if there were any marked similarities or differences between these breeds as to ERG responses. It is known that healthy dogs from different breeds but also dogs within the same breed but in different age categories may have different appearances of their ERG responses. This may be a problem when evaluating if an ERG is normal or not from a dog within a breed not previously examined. Because of this it is important to obtain normal values for each breed and age group in order to be able to use these for later comparisons of ERGs obtained from individuals affected with various retinal diseases.
In this study we have chosen to examine dogs within the three breeds: Labrador Retriever (LR), English Springer Spaniel (ESS) and Chinese Crested Dog (CCD). All of these breeds may be affected with hereditary retinal diseases such as Progressive Retinal Atrophy (PRA).
It is possible that ERG-responses vary due to a number of different factors.

Internationaliseringsprocessen för svensktillverkande företag
The world gets smaller and smaller and goods, services, people and information are nowadays more and more able to freely cross borders. Half of the Swedish GNP consists of export and almost 70 % of that amount is goods. Because of today?s increasing globalization the Swedish companies are now faced with both new opportunities and threats. Companies with goods which are manufactured in Sweden gets challenged by increased competition from cheap goods produced in other countries and companies can no longer afford to entirely focus on the domestic market.
