The purpose of this study was to look for tendencies that social media can contribute to exposing users to a stronger perception of opinion polarization, and further to see if the daily presence of social networking sites can put normative pressure on the users. The study was made using a survey with participants from Umea? University during the time frame of november-december 2014. The theoretical framework behind the study was mainly drawn from The Spiral Of Silence by Elisabeth Noelle-Neumann and was further supplemented with more current research, studying the effects from The Spiral Of Silence in the modern and more fragmented media landscape that exists now then when her theory was written. Further theoretical tools for analysis of the results came from Michel Foucault and his discussions in Discipline and punish, specifically his views on how surveillance can be discontinous in practice, but still permanent in it?s effects.The results of this study indicates that social media users tend to isolate themselves from uncomfortable opinions, and do not follow or read opinions they do not already agree with.

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Trycksår är en vårdrelaterad skada vars prevalens är utbredd på sjukhus i Sverige. Denna hudskada uppkommer när ett ihållande tryck orsakar att underliggande vävnad skadas. Riktlinjer finns utformade för hur preventionsarbetet med trycksår ska utföras, och syftar till att minska prevalensen av trycksår. Syftet med studien var att undersöka sjuksköterskors syn på trycksårsprevention relaterat till patienter som ligger inlagda på somatisk vårdavdelning. De undersökningsmetoder som användes var av både kvalitativ och kvantitativ ansats. Materialet samlades in via enkäter och det slutliga informantantalet uppgick till 29 informanter.

Många byggnader är idag fuktskadade. Fuktskador uppstår på så väl nya som gamla byggnader. Idag provtrycker man hus för att få ett värde på dess täthet, men många hus som klarar täthetskraven drabbas ändå av fuktskador. Detta beror på att otätheterna är lokala på en eller flera delar av klimatskalet bortsett från otätheter vid anslutningar.  En studie har gjorts på två väggtyper; en standardvägg och en passivhusvägg.

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Studiens övergripande syfte är att belysa och gestalta det sociala stöd respektive sociala tryck personer sjukskrivna för utmattningsdepression anser sig uppleva från omgivningen, vad gäller både att vara sjukskriven och att återgå till arbete. Undersökningen genomfördes med hjälp av kvalitativ metod, och sex personer som var sjukskrivna för utmattningsdepression intervjuades individuellt. Resultatet visar att de sjukskrivna upplever en komplex blandning av både press och stöd i processen att ta sig tillbaka till arbetslivet. Stödet, oftast i form av förståelse och undvikande av press, upplevs främst från personer i individens nära omgivning, medan pressen att återgå till arbete oftast relateras till personer och grupper på längre avstånd. Störst press att återgå till arbetet upplevdes från den "samhälleliga" normen "att göra rätt för sig", men även omgivningens okunskap och brist på förståelse upplevdes som en press. .

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

Small scale internal consumer tests provide a company with a cheap way to get valuable information regarding their products advantages and flaws. Therefore the demand for possibilities to do this kind of test has increased. This report is part of a new sensory project at Unilever. It presents a method for sensory comparison of the company?s own products with the corresponding competitor products.

Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

This essay is based on seven lifestoryinterviews with people who are undergoing orhave undergone a long asylum process. Four women and three men have contributedwith their stories about their experiences of waiting for a determination of theirapplication for residence permit. The main aim of the essay is to give betterunderstanding of how to be a refugee and a long asylum process affects people's abilityto narrate and thus examine their opportunities to be active in the construction of theirown identity.The questions that are debated and discussed are:? What can it mean for an individual's identity to escape her country and for a longtime wait for decision of asylum?? What stories can be told?? What reality are highlighted as central in the stories?? How do they handle their situation and give meaning to their lives?The analysis is based on two main theoretical perspectives: narrative theory and identitytheory. The approach is that people create meaning of events through storytelling andthat they through this process of narrating construct (and reconstruct) their identities -the self image as one have and wants to present to others.In the analysis three different types of stories are distinguished, stories that arerepresented in the empirical material: the story that can not be told, the story that mustbe told and the story that are gladly told.

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

Trycksa?r a?r ett fo?rekommande problem inom den kirurgiska omva?rdnaden som leder till o?kade va?rd- och samha?llskostnader samt ett o?kat lidande fo?r patienten. Det a?r av stor vikt att va?rdpersonalen arbetar fo?rebyggande fo?r att motverka uppkomsten av trycksa?r samt att i god tid uppta?cka om ett trycksa?r har uppsta?tt.Syftet med denna studie var att underso?ka trycksa?rsincidens efter la?ngvarig neurokirurgisk kirurgi, identifiera vart trycksa?ren uppsta?r och om de kunde kopplas till riskfaktorer.Metoden som valdes var en kvantitativ prospektiv kohortstudiedesign fo?r att resultatet skulle kunna anva?ndas i den peroperativa och postoperativa omva?rdnaden. Hudkostymen inspekterades tva? ga?nger postoperativt pa? tjugoen patienter.Resultatet visade att 76 % av studiedeltagarna hade trycksa?r efter operation och det vanligaste fo?rekommande omra?det var ha?larna.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.
