The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

This paper investigates the internal product costing system in one of the Swedish banks with the purpose to evaluate the quality of its product costs and possible implications on decision making. The study shows that the current system distorts product costs by, among other things, using relative allocation of costs and time and by allocating all costs to individual units of products. We therefore propose an alternative product costing system, which mainly draws on ABC theory but is also adapted to the specific needs of service companies and of the Bank. This proposal is intended as a solution in this particular case and not to be generalized in other contexts. We hope however to add to the understanding of why more complex costing systems, such as the ones based on ABC theory are, according to previous studies, not widely used in practice.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..

This thesis investigated if a combination of increased under colour removal (decreasing the total ink limit), normal andincreased density and modern FM-screening could be used to provide a visually better print on uncoated and coated paperin comparison with AM-screening using the same conditions.Two different test groups (one with graphic background, the other with no graphic background) were asked to a visuallyassess the quality of the prints presented in a pair comparison using a reference image.The results show that the FM-screening did not obtain any significant visual difference in comparison with AM-screening,regardless of paper types and density levels. In general however, prints on coated paper were graded higher..

Knäledsproblem är vanligt förekommande i Sverige såväl som i resten av västvärlden. Knäledsskador orsakade av yttre våld, artros och andra degenerativa sjukdomar är de vanligaste orsakerna till denna åkomma. Påverkad livskvalité, sjukskrivning från arbete, social isolering, smärta och allmänt lidande är konsekvenser som de drabbade personer kan uppleva. Syftet med studien var att beskriva kvinnors upplevelse av att genomgå en operation med total knäplastik. Fem kvinnor som genomgått en total knäledsplastik de senaste tre månaderna deltog i studien.

The purpose of this study is to investigate and describe what factors are most important to students when choosing training center, and how these factors affect the choice of each training center. We investigated this by performing a qualitative research and a quantitative survey of students at Karlstad University that trains at Friskis & Svettis and Sats in Karlstad. The results show that there are a number of important factors in the total customer experience that affects a student's choice of training center and that they also differ between a premium center and basic center. Our conclusion is that when a total customer experience concept consists of a core, core experience and peripheral experiences well linked into each other competitive advantages is created, resulting in more satisfied and loyal customers. .

Uppsatsen beskriver upplevelseproduktion med fokus på skapandet av meningsfulla arbetsupplevelser och ledarskap. Denna uppsats har skrivits under vår utbildning på Institutionen för Konst, kommunikation och lärande vid Luleå tekniska universitet. Syftet med uppsatsen har varit att undersöka om upplevelsemodellen Total Experience Management och ett exempel på ledarskap från verkligheten kan kombineras för att skapa en teori för upplevelsebaserat ledarskap.Genom ett induktivt arbetssätt och med Grundad Teori som forskningsmetod har vi tagit fram ett exempel från verkligheten av ledarskap. Vi har genomfört kvalitativa intervjuer med företaget Liveside Safety för att skapa detta exempel. Med hjälp av exemplet har vi modifierat modellen Total Experience Management och anpassat denna för Upplevelsebaserat Ledarskap.

Many media buyers annually spend money on advertising which will not be of benefit to their own brand; the fact that consumers confuse from which brand they have heard or seen commercials, comes as news to nobody. The phenomenon of media confusion has however earned much less attention. As a greater part of the total marketing budget is being spent on the media investments, on behalf of the actual advertising production, the more interesting it turns out to maximize the effects of the media expenses. The search for optimization is somewhat practised today by brand managers who are daringly adding a few more media channels to support their TV-campaigns. Buying ad space in TV is nevertheless much more expensive than the radio equivalent.

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

Detta arbete grundar sig på en befintlig ritning projekterad av Arkinova Arkitekter och uppfyller normal tillgänglighetsnivå. Ritningen består av ett lägenhetsplan med fem lägenheter vilka har en boarea mellan 36-64 m2. I detta arbete omprojekterades dessa lägenheter till höjd tillgänglighetsnivå enligt SS med avsikt att förbättra tillgängligheten för funktionshindrade grupper. Omprojekteringen utfördes med hjälp av BIM-programmet Revit Architecture 2013 med utgångspunkt från standarderna,           SS 91 42 21:2006 samt SS 91 42 22:2006, vilka utgör underlag för projektering av bostäder.       Syftet med denna studie var att utreda de merkostnader som är förknippade med en tillgänglighetsökning, dessa merkostnader beräknades i kalkylprogrammet BidCon.Resultatet visade att för att uppfylla SS rekommendationer kring ökad tillgänglighet, var en ökning av bruttoarean med 84 m2 i den ursprungliga ritningen oundviklig. Detta innebar en total ökning av bruttoarean med 25 %, vilket resulterade i merkostnader som uppgick till  126 014 SEK för lägenhetsplanet i höjd nivå.

Antalet flygresor har ökat markant i världen de senaste decennierna. Detta har medfört en ökning av flygets koldioxidutsläpp som därmed har gett en ökad påverkan på klimatet. Forskning angående människors syn på och uppfattning om flyget är relativt ny och forskning rörande ämnet är mer förekommande idag än för ett decennium sedan. Tidigare undersökningar är dock i stort sett eniga om att människor, både miljömedvetna och icke-miljömedvetna personer, inte tänker ändra på sina flygvanor och flyga mindre på grund av flygets klimatpåverkan. Denna studie undersöker klimatengagerade personers flygvanor och vad de har för syn på flyget och flygets påverkan på klimatet.

Background:  Heart failure is a multidimensional phenomenon with high mortality. Heart failure is treated with angiotensin converting enzyme (ACE) - inhibitors or angiotensin receptor blockers (ARBs) that counteract neurohormonal stimuli that occur in heart failure, as well as providing vessel dilatation, which reduces symptoms and the need for hospitalization and increases survival. Despite this, only about 50% of heart failure patients survive 6 years after diagnosis with drug therapy, and as heart failure is increasing globally, due to improved care and treatment and increasing life expectancy of the population, there is a great need for new drugs such as LCZ696 that acts by dual inhibition of the renin - angiotensin - aldosterone system and neprilysin inhibition.Objective: The aim of this literature study was to evaluate the efficacy of current treatment and possible future treatments on mortality and morbidity in heart failure patients.Results: The examined articles show that treatment with ACE inhibitors in patients with symptomatic heart failure reduces the risk of total mortality by 16% over 3.5 years, reduces all-cause mortality or hospitalization due to heart failure with NNT (number needed to treat) = 10.4 over 3.5 years and increases median survival by 9.2 months over 12.1 years in patients with asymptomatic heart failure. Treatments with high-dose ACE inhibitors reduce mortality and hospitalization because of cardiovascular causes and hospitalizations from any cause by NNT = 30 over 3 years. Beta-blockers reduce sudden death and total mortality and cardiac death or non - fatal myocardial infarction with NNT = 38 and NNT = 23, respectively, over 12 months.
