CAP KC3-12 : Design and finite element analysis
In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.
Utveckling i Ammerån : att skapa ett hållbart fiske med hög kvalitet
Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.
Anonymitetens implementeringsproblem - En studie om Kortedalas försök av avidentifierade jobbansökningar
Anonymous job applications as a method to further diversity on the labour market is widely discussed. The method aims to promote an equal selection procedure, where the employer can only judge on merits and experience. We are with this study on the other hand interested in seeing how this specific method of employment has been implemented. We have chosen to perform a small qualitative case study, of a limited attempt of this method in the government administration of Kortedala, a district in Gothenburg.Our intrests are to see whether we can, while studying a specific implementation procedure, show that any implementation problems have occurred. Furthermore explaining it by applying our implementation theory, that consists of Lennart Lundquists three criterias for explaining implementation problems experienced from the appliers' standpoint.
Markvattenhalt och temperatur i sandig jordbruksmark vid Ilstorp, centrala Skåne : en mätnings- och modelleringsstudie
Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Europa och som man i slutändan hoppas ska kunna resultera i en vinderosionsmodell. Detta har genomförts med SOIL modellen, en matematiskt fysikaliskt baserad modell för simulering av vatten och värmeflöde i en skiktad jordmånsprofil..
Kulturpolitikers syn på folkbiblioteket ? en studie i Västerbottens inland.
The main purpose of this Master thesis is to illuminate the understanding of local politicians regarding the public libraries and the librarians. We argue that the local politicians´ opinions regarding public libraries and librarians influence the way they act and react in their roles as politicians.In order to achieve the aim of this thesis we focused on following questions:What are the opinions of the politicians:- regarding themselves in relation to the public library?- concerning public libraries in general and its functions especially in the municipalities of their own?- concerning the librarians and their work in a public function?What are the conclusions to be drawn regarding the politicians´ interest and commitment to public libraries in the politic daily-life of the municipalities? Our empiric material consists of qualitative interviews with six politicians elected in two municipalities in the interior of Västerbotten, a northern sparsely populated district. In order to distinguish the various opinions that emerge from the material, we apply a phenomenographic approach. The analysis result we present in three conceivable categories in order to express the different opinions.In general our study points at a positive and favourable attitude to the public library, and all the respondents assume that the municipality ought to offer this service.
Optimalt råvarulager för biobränsleföretaget :
This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant.
Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.
Det skånska svärdet från 800 till 1300 e.Kr. : Fallstudie av 8 svärd
This essay discusses the development of swords in the southern region of Sweden, Skåne. It attempts to locate the areas in Europe where the swords were first made and, in doing so, trace the communication routes by which people traveled. The essay deals with aperiod of a few hundred years, from the late eighth century to sometime around 1300. In that sense, it is therefore also a time study tracing the cultural changes and developments in Skåne during the era of Christianization. Does the development of swords follow the overall changes in society, from an isolated pagan district to a Catholic European community, or not? In answering this question, eight swords were selected and put under closer observation.
HANDSFREE-ENHET FÖR MOBIL TRYGGHETSTELEFON
Cnior Mobile AB i Lindesberg utvecklar en mobil trygghetstelefon för äldre. Detta examensarbete går ut på att utforma en handsfree-enhet för denna. Handsfree-enheten ska integreras i larmknappen, som bärs av användaren runt handleden, och har kontakt med telefonen via blåtandsradio. I examensarbetet ingår att välja ut lämplig högtalare och mikrofon, hitta lösningar för smuts- och vattentålighet samt att lösa problem med ekon och bakgrundsstörningar.En högtalare hittades som uppfyllde kraven för smuts- och vattentålighet samtidigt som den hade utmärkt frekvensgång för återgivning av tydligt tal. Vattenavrinning från högtalaren löstes genom att ett sinussvep sänds ut från högtalaren varje gång ett samtal ska kopplas upp.
Utredning av värmepump med fjärrvärmespets
Det här är ett examensarbete som handlar om en fastighet som står på Norra Kungsgatan 37-43 som har både en värmepump och fjärrvärme för uppvärmning. Värmepumpen används i första hand och fjärrvärmen används som spets när värmepumpen inte räcker till. Detta är en ganska ovanlig kombination. Syftet med arbetet är att ta reda på om detta är en bra lösning och om lösningen är lönsam. För att få fram hur stort fastighetens energibehov är så görs beräkningar utifrån fjärrvärmedata från tidigare år samt en gammal värmepump som är utbytt sedan 2011.

Meeting, greeting & seating : a design proposal for Magomeni garden, Dar es Salaam, Tanzania
More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations.
Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist.
There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.
Naturliga filtermaterial för reduktion av metaller i dagvatten
Förorenat dagvatten från Stena Gotthards metallåtervinningsanläggning i Eskilstuna har filtrerats genom kolonner innehållande två olika adsorbenter, torv och furubarksflis. Torv är en organisk jordart som främst används som bränsle och furubarksflis är en biprodukt från skogsindustrin. Båda filtermaterialen är relativt billiga och finns i stora kvantiteter i Sverige. Filtermaterialen har visat sig ha varierande kapacitet att adsorbera metaller i vatten på grund av själva materialet samt vattnets sammansättning. Resultatet från den här studien visar att av de två undersökta filtermaterialen så har furubarksflis störst kapacitet att reducera bly, koppar och zink från det specifika dag vattnet..
PCB i byggnader : Handlingsplan för saneringsarbetet i Eskilstuna kommun
Polychlorinated biphenyls, PCBs, were used in elastic sealants in buildings during the years1956-1973. Studies of PCB have revealed that it is harmful for humans and animals,especially water-living predators and other top-predators. It is also a persistent organicpollutant and remains in the environment for a very long time. To reduce the levels of PCB inthe environment, it has to be removed from the buildings. According to Swedish law, theproperty holder has to decontaminate sealants with a PCB level of 500 mg/kg or above.
Undervegetation : användning av vedartade marktäckare i anläggning
The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull.
The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.
Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :
Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as
well as in different diary products for humans. In this EEF-work I have shown that
L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for
breeding. In a breeding stock with 3000 animals some animals had a vaginal
