Studie av belagda kolvringarmot plasmasprutat cylinderfoder : Med avseende på friktion och nötningsmotstånd
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
Förlaget och novellen : En studie av Bokförlaget Forums inställning till novellutgivning
The aim of this essay is to examine the attitudes towards publication of short stories, carried by the employees of Bokförlaget Forum, a randomly chosen Swedish publishing house. The study seeks to investigate the causes behind and consequences of the attitudes, as well as their generality. Through qualitative interviews, carried out with five of the company?s employees, the short story is defined as a problematic genre, mainly due to its low commercial success. The conclusions drawn from the interviews are put into a historical perspective, where the developments of the short story-genre, as well as that of the modern Swedish book market, are discussed.
Gotlands solelpotential
The aim of this thesis is to investigate the electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar radiation data have been collected from the Swedish solar radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total electric solar potential for the region.The electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).

Kritiska faktorer i projektimplementering : en studie av IT-bolaget EKAN Albatross AS
Denna fallstudie avser att titta på kritiska faktorer i projektimplementering. Projektimplementering avser hela genomförandet av projekt efter att avtal har tecknats till avslut, då kunden och leverantören har uppfyllt sina respektive åtaganden. Kritiska faktorer är kommunikation, ledningens stöd, planering, personal, teknik, kundens acceptans, kundkonsultation, samordning och problemlösning. Punkterna är sammanfattade i Schultz, Selvin och Pintos Projekt Implementerings Profilen (PIP). Projekt kännetecknas av att de, med dedikerade resurser under en begränsad tid, skall nå projektetmålet, vilket kan vara en nog så stor utmaning.
Sjuksköterskans möte med Anorexia Nervosapatienter : vägen till en relation. En litteraturstudie
Anorexia nervosa is a severe and multifaceted eating disorder generally found in the female population. Throughout anorectic starvation relationship related conflicts revolving round power and autonomy are bound to happen. For that reason the most crucial part of treatment should be to build a trusting relationship.The aim of this study was to describe relationship promoting strategies a nurse can use during care of anorexia nervosa patients. This literature study derives from a qualitative analysis of scientific articles. The findings indicate on five different strategies a nurse can use during care of anorexia nervosa patients.
Dagligvarumarknaden : en samhälls- och distributionsekonomisk analys av internet som försäljningskanal
Structural changes on the grocery market usually take place when the consumer is persuaded to take on the more labourintense parts of the distributionprocess. Internettrade changes this by causing competition between the unpaid work done by consumers and the labor performed by employees. In this master thesis grocery shopping on the internet is analyzed in a economic perspective with focus on distribution, changing marketstructures, driving forces and the future potential of internet as a saleschannel. The main conclusions are that consumerdemand and the belief in electronic commerceas a costreducing mechanism as well as a powerful new marketing tool were the driving forces behind the fast growth of grocery shopping on the internet. Electronic commerce introduces a new model of distribution with changing roles for consumers and grocerychains.
?Varje bok skall vara en gatsten?: En studie av ideologiska bokförlag på det svenska litterära fältet.
The purpose of this thesis is to examine a selection of ideological publishing houses in Sweden today. We want to examine where they are situated in the literary society, their terms and prerequisites. This is achieved through interviews with informants from each of the publishing houses, which we analyze with concepts from the culture sociologist Pierre Bourdieu. The publishing houses are also put in context through information from other actors in the literary field, together with previous research and other material about the Swedish book market. The main research problem in the thesis is to examine the relations between the selected publishing houses ? which profile themselves as ideological ? and the literary field where they exist.
Hur anställdas hälsa påverkas av krav, kontroll och stöd i arbetslivet

Vidare undersöks i vilken typ av arbetsbelastningsläge;aktiv, passiv, spänd eller avspänd, som den anställde skattar sinhälsa högst. Resultatet beräknades med hjälp avstatistikprogrammet SPSS och bygger på en enkätundersökning(N=137) som genomförts på arbetsplatser i tre svenska städer.Korrelationsanalyser, T-test och ANOVOR tillämpades. Resultatetvisade att höga krav korrelerade negativt med hälsa.
Ett attraktivt snittblomssortiment från perenner odlade på friland :
The production of cut flowers has diminished in Sweden and the remaining growers produce mainly in greenhouses. This situation could be changed if hardy, garden perennials suitable for Swedish conditions were to be used as cut flowers. A grower with suitable equipment as plastic tunnels or houses would be able to provide florists with an attractive assortment of perennials for cutting, during an extended selling period compared with the natural flowering period for these cultivars. This assortment would be based upon imported perennials already used by florists, but would also contain new products. To investigate the demand for locally field grown perennials as cut flowers, an inquiry took place.
Etisk utvärdering av chefers ledarskap : Vilka etiska principer bör ligga till grund för utvärdering av chefers beteende?
A reform of higher education in Sweden in 1993 led to stiffer competitive climate among educational institutions. The reform meant that educational institutions now had the opportunity to plan their curriculum autonomously. Prior to the reform educational planning was restricted to the Swedish government. The new rules spelled a greater opportunity for educational institutions to profile themselves based on their educational offerings. The higher degree of competition means that marketing becomes increasingly important when recruiting new students.
Utfackningsvägg av lättbetongblock i passivhus
AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.
"Det är alldeles för mycket sport inom idrotten" : En studie av svenska sportchefer
Authors: Lars Johansson & Johan PetterssonTitle: ?There is way to much sports in the athletics? ? A study of Swedish sportsFootball has gone from being a hobby and a popular pastime into a billion-dollar industry, and clubs around Europe are therefore operated more and more like regular companies. Sweden's position in the UEFA rankings is a modest 23 rd place, behind nations such as Austria, Switzerland and Belarus. The economic climate in Sweden is often highlighted as a strong factor. When we started our study we agreed that this could be a major contributing factor to this relatively modest rank, but believed that there were also other factors that played a big role.
Teknisk och ekonomisk analys av en bränslekonvertering vid SIA TallOils pelletsfabrik :
At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant
Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.
Bibliotekarien som distansarbetare? : förutsättningar för bibliotekarien att utföra sina funktioner på distans
We studied how librarians would adapt to telework, the performance of job responsibilitiesfrom home. We found'that all duties could be accomplished. but to varied extents.Computerbased searches, interlibrary loans, acquisitions, indexing and telephone referenceservices are the duties most likely to adapt to telework whereas cataloguing andclassification probably are best performed in the ordinary workplace.Most duties would demand access to technical means of assistance when performed fromhome. Connections to the library's local network, directly or via modem, are requiredbecause it is unrealistic to expect librarians to telework with fewer tools than theyordinarily have available. Although librarians generally believe that teleworking will nothave a large irnpact on the operation of the library, most would like to telework.Whether teleworking is a viable strategy depends on the characteristics of the duties, thelibrarian's desire to telework, but also on the size of the library, the size of its staff, thelibrary's activities, and how work is distributed between librarians..
