This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

The report is the result of a research of a building project, constructed by Peab. The report is investigating and it means to identify and evaluate qualities in the dwelling and its surroundings. Its purpose is to evaluate how the residents in a chosen housing cooperative enjoy living there. It shall, with help of chosen quality aspects, identify what expectations the residents had before moving in, how they experience the dwelling and its surroundings today, and what hopes they have for the future planning of the area.

Undersökning av luftkvaliteten vid småskalig biobränsleförbränning i två kommuner med modellsystemet VEDAIR

An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced.According to the result, there are areas with poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 µg/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Konfigurering av slutartider för ljusdetekterande mjukvara

This project measures the upper bound of exposure time for laser reflection detection in the software DotDetector. Via measurement of the exposure time for which distortion happens in a room lit with everyday light we conclude that the upper bound for exposure times are 100 milliseconds. This value does not change as long as the lighting in the room is the same. As future work this project proposes variable upper bounds depending on secondary lighting in the room. Also we propose automating the colour masking of the detection algorithm..

Participatory public art projects in run down residential areas - a discussion on how to run the process

Participation, public art and participatory public art as phenomenons and subjects have been studied and discussed. With interviews and observations as a base, we have studied projects and discussed participation, effect and quality in relation to these. Furthermore we have looked at how the participatory art processes work in Sweden and England. This essay seeks to discuss the process of participatory public art and to emphasize the elements contributing to the quality of this process. It is up to us as planners to recognize the possibilities for a qualitative place. To mediate between different interests, for example between politicians and stakeholders, between economics and quality, between the place and its users, between individuals and the community, and in our case between artists, users and the municipality. Public art has gone from being about the product, an art piece, to becoming more of a process, from non interactive to interactive. Participation ranges from receiving information to play an active part in the process. Four cases have been studied, taken both from Sweden and England, showing the diversity of processes connected to Participatory Public Art. From interviews conducted in Sweden and England information and thoughts have been received and they show a higher degree of use of participatory public art in England, and also a higher consciousness.

Analys av linjetaxering i samband med gallringsinventering med avseende på kvalitet, tillförlitlighet och framtida utformning

Modern forest owners are very familiar with forest management and forest economics. Therefore they have high demands for quality in forest operations. Guarantee of quality in the shape of self-checking activities is an important tool to guarantee a well managed forestry operation. To meet the forest owners? demands on guarantee of quality and the entrepreneurs wish of an easy method for self-checking, the forest owners association, Södra skogsägarna, has developed a new method for thinning inventory. The purpose of this study is to evaluate the method that is used for self-checking and to find ways to develop and improve of the method. The data has been collected by inventory in a number of stands with circle-area survey and with strip survey, which is method that is used for self-checking. The results show that the strip survey does not diverge more than ±10 % in measuring values of basal area, number of stems, roads share, thinning quotient, outtake of basal area and total volume compared to circle-area survey.

En undersökning av framtidametoder för att säkra förband i produktion

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

Its treatment is time-consuming and associated with many side effects. Therefore alternative forms of treatment, among them omega-3 supplementation, have been investigated. Omega-3 is a family of polyunsaturated fatty acids whose metabolites participate in the regulation of inflammatory reactions in tissues and may therefore have a positive effect on skin symptoms in patients with psoriasis.Objective: To determine if omega-3 supplementation has a beneficial effect on skin symptoms in psoriasis compared to omega-6 supplementation by rating the evidence quality in available studies.Search strategy: The literature search was conducted in the databases PubMed, Scopus and Amed.

Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Valfrihet, likvärdighet eller kvalitet? : Legitimitet för att avveckla en skola

In a suburb of Stockholm, local polititians descide to close down an elemantary school. Because of its shortage of pupils, the polititians claim they can not guarantee the quality of the school and the public requreiments of equal education. The school-employed teachers and parents of the pupils are all unhapy with the descision, but first and foremost dissatisfaied with how the descision was communicated.Using qualitative methods; interviews and content analisys, this thesis aimes to determine how the involved parties, in regards to the termination of the school, view the concepts of freedom of choice, equal education and quality. Interviews have been made with decision-makers, employees of the school, the school leader, one civil servant and parents; all with the goal of understanding how the involved parties view the events leading to the termination of the school and what causes they see. Furthermore, the thesis analyses if and why the involved parties experience the decision as legitimate..

Förbättring av intern kvalitet i MediusFlow genom utvärdering av arbetsprocessen samt verktyg från Visual Studio 2010

I maj 2009 släpptes den första betaversionen av Visual Studio Team System 2010. Den innehåller en rad intressanta nyheter och funktioner som kan underlätta utvecklingsarbetet och höja den interna kvaliteten.Kvalitetsbegreppet inom mjukvaruutveckling kan delas upp i två delar: extern och intern kvalitet. Med extern kvalitet menas det som kunden ser, till exempel att rätt funktionalitet utvecklas och att den levereras i tid. Intern kvalitet handlar om processer inom företaget och det som kunden ofta inte ser eller är medveten om.Nyheter i Visual Studio 2010 har utvärderats i fokusgrupper tillsammans med rutinerade utvecklare på Medius. Den agila arbetsprocessen har utvärderats utifrån observationer, informella intervjuer samt den teoretiska referensram som ställts upp.Utvärderingarna har resulterat i ett antal riktlinjer för hur Medius kan förbättra sin interna kvalitetsprocess.

Kastrering av smågris : bättre djurvälfärd med hjälp av farmaka

The castration of piglets is performed routinely all around the world. Most castrations are done without anaesthesia and analgesia, despite the fact that this procedure has been proved to induce acute pain and stress for the piglets. The procedure regarding castration of piglets is currently a hot topic of debate and an important political issue. The underlying issue is the boar taint which are highlighted in the heating of the meat after slaughter, which in turn can lead to reduced meat sales as it can be perceived as unpleasant for many consumers. The purpose of this study is to examine alternative drugs which may be selected in order to replace the practice of castration of piglets without anaesthesia, in light of improved animal welfare.
