Olyckskorpen - finns han?
Detta examensarbete utreder frågeställningen om den såkallade "olyckskorpen" ? alltså yrkesarbetaren som är inblandad i flertalet arbetsplatsolyckor ? verkligen existerar. Frågan är lite av kontroversiell typ och har diskuterats sedan 1940-talet, utan något avsevärt utslag eller dokumenterat alster.Samarbetspartner blev NCC Construction och två av deras stora arbetsplatser i Stockholmsområdet valdes som mätfält; Söderby samt Frösunda.Undersökningen baserades på datainhämtning genom enkätformular till yrkesarbetare och ledning på de utvalda arbetsplatserna, genom erfarenhetsinhämtning från platschefer och lagbasar inom NCCs organisation samt från YTH-studenter på byggprogrammet. Författarnas egen erfarenhet från branschen har också vägts in i bearbetningen.Resultatet gav ingen olyckskorp att sätta fingret på, men en indikation från samtliga håll att egenskaper som kan knytas till olyckskorpen förekommer i branschen. Detta gav upphov till en teoretisk modell att användas för att ringa in olyckskorpar på individuell nivå i en vidare undersökning..
FRI KÄRLEK - FÖR VEM? Respektabilitet och konstruktionen av 'fri kärlek' i Frida Stéenhoffs dramatext "Lejonets unge" sett ur ett intersektionellt perspektiv.
The purpose of this thesis is to investigate respectability and the construction of ?free love? in Swedish feminist debater and playwright Frida Stéenhoff?s (1865?1945) drama Lejonets unge (1896). In 1897 the first production of the drama was set in the small town of Sundsvall in Sweden and caused a public storm be-cause of its plea for free love for both men and women.Through an intersectional perspective, where the axes of class, gender, sexual-ity, religion, nationality and age are central and with a starting point in Beverly Skegg?s concept ?respectability? I investigate how ?free love? is constructed in the drama. I also link the construction of ?free love? to the historical context of the debate concerning sexual morality and marriage which was intense in society and literature in Scandinavia in the late 19th century.In the drama the plea for ?free love? is created mainly through the character Saga Leire.
Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)
Peat lands are a great potential resource for increased forest growth in Sweden, there are approximately 6.5 million hectares of peat lands, whereof around 70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste land. There are over 200 000 hectares of peat land that is already drained and wooded, and that may be suitable for fertilization. Forest production on peat soils usually requires drainage and fertilization. Dewatering requires ditching the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The purpose of this work was to examine the effects of potassium fertilization on the growth of spruces that were planted on drained peat land and how different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance transport in the tree. Potassium is also important for the carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter resistance of many species. Potassium is not found in any organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was left without fertilization. All plots that were fertilized with potassium grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality estimation of wetlands after ditching (dikningsbonitering). The plot with most potassium produced after fertilizationaproximately in level with theoretical estimations. Key words: Peat land, Fertilization, Ditching, Growth, site quality..
Byggproduktionsplanering : En studie av metoder och verktyg
Examensarbetet redogör för byggproduktionsplanering med en fördjupning inom tidsplaneringsmetoder- och verktyg, vilka kan användas som hjälpmedel inom området. Inom fördjupningen gjordes två praktiska försök och intervjuer genomfördes för att få en verklig bild av hur planeringen fungerar, samt för att få feedback på försöken. Arbetet resulterade i slutsatsen att olika planeringsmetoder bör användas i olika skeden av byggproduktionsplaneringen, samt att de olika planeringsmetoderna är till olika nytta för de varierande arbetsrollerna i en byggorganisation. Man kan med fördel använda sig av en kombination av planeringsmetoderna, CPM, LOB och den relativt okända ?Kontinuitetsmetoden? när man planerar och styr sin byggproduktion.
"Men Du är ju svensk!" - en kvalitativ studie av adopterades möte med det svenska samhället ur ett identitetsperspektiv
AbstractThe aim of this essay is to bring understanding to one of the problems theinternationally adopted in Sweden might face, the identity dilemma. In order to do so, a theory of identity construction, Constructionism, is used. This theory says that the construction of identities is a constantly continuing process, influenced, not only by our own perception of ourselves, but also by how we are viewed and treated by otherpeople.Given this theoretic starting point, an examination of the adoptees? everydayencounters in the Swedish society is made, using an autobiography, a biography, a collection of interviews, and newspaper articles. The result shows that the internationally adopted, although they are Swedish both by mind and by law, experience that they have been, and sometimes still are, confronted with strong attitudes such as racism, prejudice and stereotypes.Furthermore, those who experience the identity dilemma often refer to how they are perceived by ?the others?, or to what the encounters with ? the real? Swedes have been like.
Vare sig Kurd eller Svensk : En tredje identitet i ett mångkulturellt och transnationelltSverigePerihan
AbstractThe essay presents a qualitative study, which intends to investigate how the identityconstruction of the second generation of young people with Kurdish origin has been formedconsidering the complexity of living between two or more different cultures as well theinfluence of family norms and values. The theoretical basis lies inthe identity construction and ethnic identity in which we have tried toexpress and illustrate this complexity. Previous research we have assumed includes affiliation,and a third identity, where we have used a number of researchers studies to elucidatethis topic. In order to facilitate the study, ten in-depth interviews with Kurdish youths aged18-25 years have been applied. The common factor for these respondents is that they all cameto Sweden at a young age.

Subventioner och hyresrätter? En bostadspolitisk studie
Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.
Skattning av fordonsmassa med driftstatistik
In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.
Framtidens D250S Dual batteriladdare
This thesis aims to develop proposals and models for a modular electronics construction to a future D250S Dual battery charger. The aim also includes investigation of possibilities to use some of Texas Instruments C2000 microprocessors. The reason for this is that CTEK SWEDEN AB wants to renew the present D250S Dual battery charger and lower the manufacturing costs. The thesis work has involved gathering theoretical facts for the development of a design on the modular electronic construction, the choice on which microprocessor to use, the choice of electronic components and facts about peripheral equipment to the D250S Dual. With the theoretical there has been developed different solutions to the proposed hardware and software solutions with comparisons in aspects of positive and negative.

This report intends through qualitative interviews, to analyze the knowledge and attitude towards incident reporting among the employees of the Swedish construction contractor JM.The goal of the thesis work is to hopefully contribute to an increase of employees? awareness on those issues.
Prefabricerade passivhusväggar
Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.
Konstruktion av en autonom vindstation
Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.
Konstruktion av current conveyors via makromodellering
A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.
