This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..

Bakgrund: Övervikt och fetma är en global epidemi. Fetma kan orsakas av arv, miljö och beteendemässiga faktorer. Övervikt kanleda till flera följdsjukdomar. Viktminskning kan ge ökad livskvalité pch psykiskt välbefinnande. Ur ett hälsoekonomiskt perspektiv är det av vikt att det hälsofrämjande arbetet startar tidigt i barndomen.

The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.

Ett lågtröskelboende vänder sig till individer med missbruks- och boendeproblematik där intentionen är att erbjuda individen stöd i dennes alkoholproblematik samt en trygghet i boendet utan att ställa krav på nykterhet. Studiens syfte var att undersöka fenomenet: upplevelsen av att bo på ett lågtröskelboende utifrån ett brukarperspektiv, samt vad flytten till lågtröskelboendet har inneburit för de boendes livskvalitet. I analysen användes ett fenomenologiskt perspektiv med livsvärldsteorin som utgångspunkt. Resultatet visar studiens fenomen som existentiell samhörighet i alkoholmissbruk. Den delade alkohol- och boendeproblematiken gör att de boende upplever sig som jämlika med varandra, vilket också skapar en känsla av gemenskap och tillhörighet.

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

Physical activity is required for a good health and science shows a clear connection between exercise and a lower risk for disease. Still, the physical activity among the population is far from good. It is the individuals own responsibility to exercise, but the society also has a responsibility to give opportunities to exercise for the population. The aim with the study was to investigate what motivated the group of physical active people to use the Central hospital in Kristianstad?s health program.

This thesis aim to investigate the living conditions among marginalized habitants of suburbs in the Swedish welfare state. To approach an understanding of the complexity of marginalized urban areas, this thesis focus on studying the Stockholm suburb Husby in a context of the May riots 2013.The research method used is qualitative interviews with seven informants, who have a connection to the Husby area.The theories applied to the empirical material is Gösta Esping-Andersens theory on welfare state regimes and Loïc Wacquants theory on advanced marginality, also known as ?The new urban poverty?.By observing the complexity of the Husby riots in a contextual aspect of the Swedish welfare state and the living situation in Husby, the analysis has shown that the Swedish welfare model is going through a changing process. This process means a shift from a social democratic welfare model towards a more liberal regime, with an increased privatization of public welfare and a focus on individual responsibility regarding the citizens own living conditions. Husby as an area is characterized by a low socioeconomic status, a high level of unemployment and poor school results.

Fusarium graminearum causes reduction in both yield and quality in cereal grain worldwide. One of the diseases it can cause is Fusarium Head Blight (FHB). Both sexually and asexually produced spores can infect living plants. Asexual conidia are produced in the mycelium while sexual ascospores form in asci in perithecia on debris. In biological control, living organsims are used to control pests and diseases.

During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.

In the Western world the interest in science in schools is steadily declining. Focusing on interest is important to encourage students to lifelong learning which is a written purpose of the Swedish curriculum. This literature study examines if biology education outside in nature could be a part of the solution for this problem and the question of issue is how can education outdoor enhance students? interest for biology and what other aspects does this effect simultaneously? The method of block search was selected for addressing this question, utilizing the ERIC and ERC databases. The results show that situational interest increased with outside education due to aspects such as: novelty, hands-on, knowledge acquisition and social interaction.

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

In the post-war era many European countries were recovering from the ravages of the bombings of the second world war destroying whole countries. Sweden being neutral was spared the destruction of war but instead we demolished almost as much housing all by ourselves. A social program was modeled to modernize the country and to drag the swedes out of poverty by building one million apartments in just ten years and demolishing the old, dilapidated working-class neighborhoods. The traumatic events of the demolition of large areas of both the central and the outskirts of most Swedish cities is still very much present in the collective memory of people today and the new modernistic districts are still paying the price of that, more than fifty years later. Today these modernistic districts are in need of repair, and they are often homes to groups alienated from society making their reputation even worse.

The aim of this masters thesis is to examine what political, social and ideological reasons that were the base for the establishment of the Swedish temperance movement. Which judgements within this movement that resulted in the decision to establish publishing firms, how these publishing businesses were organised and what function they had in the literary circuit. The questions are: What principal political, social, economical and ideological reasons were the bases for the establishment of the Swedish temperance movement? How has their need for publishing firms arisen? Which were the publishing firms and who were the publishers? What ideas, purposes, experiences, values and judgements led to the establishment of publishing firms? In the first part of the theory I have used the historical materialism of Karl Marx; in the second part the theory of middle class publicity by Jürgen Habermas; and in the third part I have made a presentation of the literary circuit and how it works according to Marx and Habermas. The method used is an analysis of ideas and ideologies in literature and documents.

This thesis examines the way that subversivity is produced in relation to the name of the author, as understood by Foucault, and what potential for ressistance that can be glimpsed there. This from the reading of three text that in different ways relate to that theme.Firstly, throught the reading of "Isis mamma a?r genusvetare, skribent och konstna?r, min mamma a?r f.d. sta?derska, kokerska och dagisfro?ken, numera fo?rtidspensiona?r med diagnosen fibromyalgi" by Lidija Praizovic?, a text that actively work with the internal production of different exteriorities.
