The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

The lifecycle of fashion products get shorter and shorter. Companies in the fashion business needto make sure that they can offer their customers the right products, in the right quantity at theexact right time. The competition on the fashion market today is tough and if companies aregoing to be successful they need to have access to the most reliable suppliers, and also offer theircustomers products with high quality to attractive prices. It is therefore of highest importance toevaluate and choose the right sourcing strategy. Product category and type of organisation aresome of the factors that will determine which strategy that is most appropriate.

This report is the result of a thesis at the company Sanmina in O?rnsko?ldsvik. The thesis is the final work at the mechanical engineering program at Umea? University.Sanmina has in 2015 launched an initiative to ensure that all sites are using LEAN principles and tools to enhance their business. As part of the plan for the LEAN-work, an LSS (Lean Six Sigma)-project has started to study the company's receivehall and inspection.

SNA Europe?s handsaw concept is called ?Bahco Handsaw System? and is constituted by a saw handle with the possibility to switch between different saw blades. The sales of ?Bahco Handsaw System? products have not achieved the desired results probably due to the high price. Developing a more cost efficient handle, enabling a lower consumer price of the product, is assumed to increase the sales volume.

SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.

This Master?s thesis concerns the information behaviour of pastors in nonconformist churches (especially new evangelical and Baptist church communions) in Sweden in their spiritual service to the local parish. The thesis also looks into how the information flow functions in the pastors? context and why the information need appears as it does. The theory used in this study is contextual analysis based on Buckland?s, Weber?s and Patrick Wilson?s theories on authority and power structures.

The theoretical focus in this master is information retrieval (IR), and especially the part of IR that includes interactivity. This research is by some researchers called IIR. Our principal aim was to examine if search engines on the WWW are taking advantage of research results from IIR research. A way to do this is to look at the application of special features, in this case query expansion (QE) and relevance feedback (RF). Both these methods aim for a better matching of documents and the searchers information need.

As a result of a successful human development around the world an extensive urbanization of societies are taking place that are networked in various ways. In these networks, increased travel and digitization are central where individuals and organizations converge in a constant and immediate wireless and mobile technology flow. An example of this is Stockholm and its public transportation company Storstockholms Lokaltrafik (SL). Although most participate in most of the network society, SL is struggling with an audience that seldom travel with them: families with children. We intended to find out how the communication of SL´s digital platforms could get families to travel more with public transportation.

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Root rot causes large economical losses for Swedish forestry. The spread of root rot can partly be prevented by treating the spruce stumps in thinnings. Late pre-commercial thinning (PCT) is one of the forestry measures where stump treatment is not used. Late PCT can be defined as: The act of cleaning the stand with the aim of improving accessibility and sight within the stand, and so to increase the mean stem´s volume during the first conventional thinning. The aim of this study was to examine how late PCT is performed, its spatial extent and if it aids the spreading of root rot. The study was limited to encompass late PCT before first conventional thinnings in spruce stands in southern Sweden. Samples of spruce stumps were taken from four stands where late PTC had been carried out.

Fleets have the ability to affect an adversary?s use of the seas for transportation. Nations have in numerous occasions exercised this power in order to ravage their opponent?s trade in times of conflict with the purpose of diminishing their military might. Great naval thinkers like Mahan and Corbett have described this use of seapower during conflicts in great depth but theories regarding the use of seapower to affect a nation?s peacetime economy in order to achieve limited political goals is lacking.

Denna undersökning utgår ifrån Mary Jo Bitners servicescape-modell om hur fysiska miljöegenskaper formade efter en berättelse eller tema påverkar serviceverksamheter. För att sedan implementera modellen i en digital miljö. Resultatet av att nyttja teorierna kring servicescapes på exempelvis serviceverksamheter ger besökare möjlighet att fly undan vardagen, medvetet eller omedvetet, genom en kombination av olika sinnen. I undersökningen såg vi att besökarens självmedvetenhet kunde jämföras med Mihaly Csikszentmihalyis teorier om ?flöde?, där medvetandetillståndet hos en individ blir uppslukat av individens aktivitet.

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.
