Optisk sortering av matavfall : en jämförelse med en minskning av svinnet
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.
Över tröskeln : Ett nytt boendefenomen
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.
Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050
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..
?Jag tyar inte idag!? En kvalitativ studie om motivationsfaktorer till fysisk aktivitet i samarbete med Centralsjukhuset i Kristianstad.
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.
Biologisk bekämpning av Fusarium graminearum
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.
Upprättande av mall för fuktsäkerhetsbeskrivning : Genom granskning av projekt ur fuktsäkerhetssynpunkt
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.
Naturens p?verkan p? elever i skolan: En forsknings?versikt ?ver hur biologiundervisning utomhus p?verkar elever med fokus p? intresse
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.
Valsningsteknik för extremt höghållfasta tunna stål
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.
"Om jag är dålig jag slutar" : En studie av grammatiska avvikelser utifrån processbarhetsteorin i skönlitterär andraspråkssvenska
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.
Den skeva bilden : En studie i hur brottsrapporteringen i Efterlyst ser ut jämfört med brottsstatistiken, samt hur programmets tittare upplever att de påverkas
The purpose of this thesis was to determine the tv-show Efterlyst?s (Wanted)effects on viewers when it comes to how crime, criminals and victims are portrayed in the show. In order to achieve the purpose of our the study, both quantitative and qualitative approaches were used We compared the image Efterlyst gives of crime, criminals and victims to statistical information from The Swedish National Council for Crime Prevention and The Central Bureau of Statistiscs. By using focus-groups we also studied how Efterlyst portrays, in the season of 2009, and how it may have affected its viewers. Our conclusion was that there are important differences between how Efterlyst portrays crime and the image of crime the statistics gives.

Dämpning av fläktljud i diskmaskin
Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.
Kontorsskiftets påverkan på organisationskulturen : - Ett skifte från cellkontor till öppet kontor -
The essay discusses the effects that changes to the office plan have on organizational culture. Information about actual change as well as expected change in organizational culture was gathered before the empirical research was initiated. The empirical research was carried out at the Customer Logistics department at Ericsson through: an interview with a manager in charge of the relocation and design of the office, a manager for the specified department and also five employees of this department. The empirical studies show that there was a significant change in organizational culture and that results were not always as expected. There was a loss in symbolic actions, which needed to be compensated for, a perceived Reduction in spontaneous communication, and a mixed response of perceived change in social interaction.

VTA-aggregatet : En undersökning av driftegenskaper och funktion vid slowsteaming.
Turboaggregat med variabel geometri har länge funnit hos automobiler, men det dröjde ända tills 2008 innan det första dök upp på ett fartyg. Syftet med denna undersökning har varit att kontrollera om de fördelar som Man B&W hävdar att VTA-aggregatet skall ha stämmer, samt att undersöka om VTA-aggregatet kan lösa de problem som uppkommer i och med att man kör med reducerad fart, s.k. slowsteaming. För att undersöka detta har jag bedrivit litteraturstudie, med insamling av data mestadels från Internet.Resultatet av undersökningen visar på att ett VTA-aggregat kan minska bränsleförbrukningen och vissa emissioner vid reducerad fart jämfört med en konventionell turbo av samma storlek. Den minskade bränsleförbrukningen leder i sin tur till ekonomiska vinster.
