According to a decision of the European Commission, measures are to be taken to reduce the use of energy in the EU. The goal is to reduce it by 20 % compared to the current use. This shall be done to the year 2020 (European Commission, 2011). One industry that use large amounts of energy is the construction of buildings which account for almost a third of the energy use (Brogren, 2012). The major part of the energy that is used in the construction industry is not used when the buildings are built, but rather during the rest of their subsequent lifetime.

Byggbranschen anses vara en konservativ bransch både vad gäller teknik och samarbetsformer. Det oerhörda trycket på byggbranschen och det stora antalet byggprojekt som utförs idag gör att en del komplikationer uppstår. Detta kan bl. a. bero på tidsbrist, kompetensbrist och samarbetsproblem.I vissa projekt fungerar samarbetet utmärkt mellan projektets olika parter men i allt för många projekt är samarbetet mellan parterna bristfällig.

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Detta arbete har syftat till att undersöka möjligheterna till förbättring av material- och produktionsstyrning vid Sandvik Mining and Construction i Sandviken. Målet har varit att skapa ett underlag för förbättrad styrning av ingående material. Nulägesanalysen visade att förbättringspotential fanns inom klassificeringen av hårdmetallämnen och komponenter. Dessutom var det önskvärt att ett kanbansystem uppfördes på de förslipade hårdmetallstiften som går till den helautomatiska STAMA-cellen. Examensarbetet har gett underlag för en omstrukturering av denna klassificering men även för en framtida uppdatering av den.

Den här rapporten avhandlar arbetet med att ta fram ett förslag som förlänger Volvos kärnvärden - kvalitet, säkerhet och miljöhänsyn, ut i Utvecklingsverkstaden på Volvo Construction Equipment, Hauler Loader Business Line, i Eskilstuna.

En modell av verkstaden i skala 1:50 utformades som presentationsmedium.Vid examensarbetets slut har förslaget presenterats och utvärderats av målgruppen. Den primära målgruppen har varit de anställda på avdelningen.Slutsatserna av arbetet är att en informationsbärande interiör kan formges för att representera ett företags kärnvärden och visa på innovation och framtidstänk.

Detta examensarbete har utförts på högskoleingenjörsprogrammet för Byggteknik och Design vid Kungliga Tekniska Högskolan i samarbete med Svensk Bygglogistik AB. Arbetet diskuterar betydelsen av byggnadslogistik i ett infrastrukturprojekt för att uppnå en högre utnyttjandegrad för grävmaskiner med stöd av logistiksamordningsverktyg.Sammanlagt har 2150 mätningar utförts under två veckors tid för att kartlägga utnyttjandegraden för en bandgrävare (EC250CL) och en hjulgrävare (Atlas 1505M) på ett referensprojekt i Stockholmsregionen. Resultatet har sammanställts separat för de olika resurserna genom att redovisa och analysera andelen outnyttjad tid och de bakomliggande orsakerna till den outnyttjade tiden.Resultatet visar att utnyttjandegraden för bandgrävaren är 53 % och 59 % för hjulgrävaren vilket tyder på att ett förbättringsutrymme finns.Avslutningsvis diskuteras rekommendationer för hur användning av logistiksamordningsverktyg kan utökas inom anläggningssidan..

?The trees importance to the street? discusses just that, the trees importance to the street. The purpose of this paper has been to examine what influence the trees have on streets. By writing about good examples of how trees can add good qualities to a street I wish to inspire to more use of trees in future city-planning. I have examined three streets in Malmö and three streets in Berlin and analyzed the trees influences there through the help of literature by three authors: Great Streets (1993) and The Boulevard Book (2002) by Allan B. Jacobs, Trees in Urban Design (1993) by Henry F.

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

The present work is a continuation of the ideas developed in previous projects during my Masters studies that explored the relation between pattern, form and space. Starting from the pattern multiplication for space construction the present project proposes textiles as an assortment of flexible expressions. The purpose of the project is to explore aesthetic and functional potential of textiles for out door temporary structures. This is to create a pattern interface which filters sunlight through a textile surface to offer instant sheltering solutions for out door activities. The project combines research and analyses of outdoor temporary structures and scope of textile in the area.

The society of consumption exposes us to a lot of information, where advertisement constitutes an extensive part. Due to its expanding, advertisement receives a natural and obvious space in our everyday life. This study aims to investigate how social and cultural values can be mediated in advertisement. The focus has been put to ideas related to health and fitness in the advertisement of power drinks. The thesis takes social constructionism as a starting point, and combines image- and critical discourse analysis in purpose to analyze the pictures.Sociology of consumption, construction of identity, lifestyle and everyday life all constitute an essential part of my analysis.

Den här studien använder sig av en queerteoretisk utgångspunkt för att försöka reda ut vad som kan sägas om genuskonstruktionen i två välkända religiösa berättelser: den hinduiska Ramayana samt Ruts bok som återfinns i den hebreiska bibeln. Studien använder en hermeneutisk metod och en queerteori med teoretiska modeller av Judith Butler och Yvonne Hirdman. Det kan ses i båda berättelserna att genuset hos både manliga och kvinnliga karaktärer ändrar sig under berättelsens gång, flera gånger och i relation till varandra. Slutligen diskuteras resultaten och det visar sig att den teori som används i uppsatsen, queerteori, saknar en förståelse för det slags dynamiska genus som finns att se vid en läsning av Ruts bok och Ramayana..

The essay is a text centred study of ten Young Adult Novels, in which Internet plays an essential part. The structure is put into light out of used narrative techniques of how to create stories and its construction elements. I compare the ten Young Adult novels to each other. My aim is to analyze the functions of the Internet motive in the chosen novels, using different approaches, and enlighten it with concerns to the new phenomenon that Internet is in society. Consequently the essay will also have a mimetic touch to it.The ten novels that I base the analysis on are written of both med and women and have both male and female as main fictive persons, and are from different parts of the world.

In this paper I study how the minority group Roma appears in the Swedish media. I also look at possible similarities and differences in appearance before and after the disclosure of the Roma registration by the Swedish police in September 2013. To answer my purpose with the paper I treat the following questions:How is the minority group Roma constructed in the media before and after the disclosure?In which ways are the minority group Roma expressed in the media before and after the disclosure?I am using a discourse analytic method based on theories of construction between ?them? and ?we? and the media?s impact on social constructions and identities. By analysing twenty-eight articles from a period of one month before and one month after the disclosure the result shows that there are more similarities than differences between how the Roma are described in the Swedish media.

This paper aims to explore the phenomenon urban wind energy, its visual effect on built environment and the factors that affect the opinion towards new elements in the city. A place study of the city Gävle serves as a complement to the theoretical part of the paper. The theoretical discussion opens with an account for the technical and economical conditions of urban wind energy. It presents the technical basics, different types of turbines and a discussion occurring wind related techniques in built environment. Today, the knowledge of how the wind moves and acts in the rural landscape is quite good.
