Testbänk för motorbåtsdrev
Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.
FUNDAMENTALA SAMBAND I TURBULENTA PERIODER: - Om tillväxtens och avkastningens påverkan på börsvärdet under perioden 1997-2005
This thesis investigates the effect of profit growth and profitability on market capitalization amongst Nordic companies during the turbulent period 1997-2005. Our results suggest that profitability have a significant impact on market capitalization for six of the nine years studied, whereas profit growth does not seem to affect market capitalization. Consequently, our results imply that the effect of other factors on share price performance may be greater than previously suggested. These findings are only partly in line with theories on corporate valuation which suggest that market capitalizations are to a great extent driven by both profit growth and capital returns, regardless of whether the stock market is particularly unstable..
The change of haemoglobin during blood donation, and an assessment of a photometrical method for non-invasive haemoglobin analysis
In Sweden, lowest acceptable haemoglobin levels in blood donators are 125g/L for women and 135g/L for men for a test sample taken in the beginning of the blood donation. Levels, which are 10g/L lower, are accepted if the sample is taken after the blood donation. Earlier studies show that the haemoglobin level decreases for a person that is lying down.The two aims of this study were to examine how much the haemoglobin levels change during blood donation and to examine if the photometrical instrument Pronto-7TM shows equivalent results to that of the established method Cell-Dyn Sapphire.In the study, 120 blood donors participated. Blood samples were taken in the beginning and in the end of the donation. Analyses by Pronto-7TM were done before and after the donation.The haemoglobin level decreased significantly during the blood donation.
Kreditgivningsprocessen : Hur humankapital och risk bedöms vid kreditgivning av nyetablerade småföretag
Small business enterprises have escalated in Sweden during the last decade. However, new established companies are struggling to maintain their selves during the startup process and according to a survey from Tillväxtanalys, only 68 % of startup companies from 2008 were still active three years later. One of the main reasons is lack of capital and the most common approach to finance companies is to apply for a bank loan. In other words, commercial banks are of great importance for new businesses. Although, the problem arises when there is no previous history from the new businesses that the bank could base its credit assessment on.
Alternativ till fortsatt elektrisk generering i Olidan
In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.
Automatiserad laddning och plundring mellan magasin
This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.
Yrkesroll och konsumtion : En undersökning hur/om individen utifrån sin yrkesroll väljer att konsumera.
Vi ville i den här kvalitativa studien studera om individer konsumerar olika utifrån sina yrkesroller. Om individer t ex genom sin konsumtion försöker att kompensera ett arbete utan upplevelser eller tillfredställelser? För att få svar på våra funderingar så har vi intervjuat individer inom chefsyrken och arbetaryrken, för att få perspektiv på om och konsumtionen skiljer sig åt och hur. Vi har även visat på olika teorier som tar upp de teman som vi valt att förhålla oss till under studiens gång. Dessa teman går som en röd tråd genom hela uppsatsen och behandlar konsumtion, roll/performance, klass/status.
Mediadatabas med webbgränssnitt för hembygdsförening
Throughout the years the Swedish local history societies have collected a large quantity of material, consisting of photos, documents and items, among others. As the society has become more computerized, the need has increased for these collections to become digitalized. This is a way to make their media more easily accessible to the general public, but also to easily be able to archive and preserve for example photos and videos electronically.This thesis concerns itself with the work we have done for the local history society of Nyed in Molkom. The task set before us consisted of creating both a website for the society, and a reliable database from witch the website draws its information. This project allows anyone with administrator privileges to upload new files and any additional information.
Den teoretiska utmaningen - En undersökning om nyinstitutionalismens (o)förmåga att förklara förändring.
This thesis aims to examine the possibility of understanding social change by using new institutionalism approaches on a specific case, The case, which describes the implementation of new public management reform in the Swedish health care system, is analysed from two separate new institutionalismperspectives; the tool perspective and the symbol perspective. These approaches differ from one another in the sense that the first relies on a rational choice ontology, while the latter rather refers to a sociological tradition. In the analysis, causal explanations as well as aim related explanations are presented. Formative moments such as economic stagnation, non-socialist governments and ideological isomorfism are presented as important factors behind the reformation. By using the tool perspective, the motives of the idea spreading and reformation of the Swedish health care system, are connected to a strictly rationalbasis such as cost efficiency and quality improvements.
Systematisk Arbetsmiljöutbildning i en svensk kommun
Arbetsmiljöverket har under 2008 och 2009 gjort inspektioner hos Hudiksvalls kommun. Arbetsmiljöverket konstaterade i samband med dessa inspektioner att chefer och arbetsledare saknade kunskaper om arbetsmiljölagen och dess föreskrifter. En utbildningsplan inom kommunen var lagd under 2009 för att rätta till dessa brister. Hudiksvalls kommun har en önskan att veta om utbildningen i det systematiska arbetsmiljöarbetet gav förbättrade kunskaper inom området. För att ta reda på om utbildningen gav förbättrade kunskaper har en undersökning gjorts mellan två grupper, varav den ena inte har gått arbetsmiljöutbildningen.

Alkoholintag efter träning och dess inverkan på muskeluppbyggnad och återhämtning hos vuxna män - En systematisk litteraturöversikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Alcohol consumption after training and its effects on muscle gain and recovery adult menAuthor: Frida Carlstedt, Puck JanssonSupervisor: Frode SlindeExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 09, 2014Background: Today, the Swedish population exceeds the recommendations for alcohol intake while advised to move at least thirty minutes a day. It is well established what happens if you drink alcohol before a workout or if you workout the day after an alcohol intake, but it is less well established how muscle gain and recovery are affected by an intake of alcohol in the phase of recovery.Objective: The objective of this review is to investigate if there is a relation between alcohol intake after a workout and effected recovery and muscle gain. This was performed by measuring the outcomes cortisol, testosterone, creatine kinase as well as different measures of muscle strength. The issue was ?Does an intake of alcohol after training affect recovery and muscle gain??Search strategy: A systematic review in the databases PubMed and Scopus with the MeSH-terms: exercise, muscles, recovery of function, training, athletic performance, performance, sport, alcohol drinking, alcohols, alcohol and ethanol.Selection criteria: Criteria for articles to be included in this review were that they would be RCT- and human studies in healthy subjects as well as containing an ethanol intake after a physical activity that consisted of weight training in the form of resistance training or other forms of activity that promotes strength.Data collection and analysis: A systematic search for literature as mentioned above (search strategy) was performed as well as an analysis with the SBU quality review template for randomized studies, and a quality review for each measure of outcome according to Gothenburg University summarized evidence template for measures of outcome.4Main results: Many studies are authored by the same group of researchers and/or are of a lower quality.
Kulturen bakom kulturen - En komparativ studie av kultursynens inverkan på tyska och svenska kulturpolitiska strukturer
This thesis aims to develop a theory in the under researched field of international comparative cultural policy studies. lt does so by combining theories from the fields of political scienceand cultural studies, researching how and to what extent the concepts of culture of different states have an impact on the way cultural policies are constructed.The thesis uses this theoretical development in order to research a specific problem, namely the perceived possibility that Swedish and German cultural structures are slowly converging. Two recent official policy documents from each country are the objects of study. Through comparative idea analysis and with Michiel S. D Vries theories on decentralization, the thesis explains the convergence between the countries by differing cultural views between them.
Den skapande gränsen - En analys av sömnmotivet i Daniil Charms prosatexter
The aim of this master thesis is to study the reliefs of a Romanesque tombstone from 1130 AD, with the intention to form a plausible understanding of their meaning. During the course of the investigation, my main focus will be on collecting materials of an iconographical and historiographical nature, as they appear in previous studies. I will also use performative analysis when examining the tombstone. Consequently this thesis can be seen as a survey of history and place; early Christian iconology as well as the experience of the viewer. As a result, the 900-year-old tombstone will not only be seen as a memorial in this text, but also as a performance of one man?s faith and as representing the core message of the early Christian church.The tombstone is a rarity in Swedish art history and well worth a closer examination.
