GIS-baserad habitatmodell för mindre hackspett, ett verktyg för att bevara skyddsvärda lövskogar inom Umeälvlandskapet :
Deciduous forests are, according to the National Environmental Quality Objectives, a priority area. Deciduous forests are rich in species and the occurrence of dead wood is an important factor for biodiversity. In order to identify valuable deciduous forests for bio-diversity, conservation needs good analyses and planning tools. Habitat models combined with geographic information systems can be used to study the spatial structure of suitable habitat. The Lesser spotted woodpecker (Dendrocopos minor) has been proposed as an indicator species for deciduous forests, since this species is highly specialized on insect larvae in dead wood and requires large areas of deciduous-rich environments.
Many riparian forest with high species richness and high nature conservation values are found along the Ume river in Umeå municipality.

Abstract______________________________________________________________________Title:A study about creating understanding for different kinds of empowermentLevel:Bachelors thesis in Business Administration, 15 creditsAuthor:Fredrik LegovicSupervisor:Tomas KällquistDate:2014 - JuneAim:The main purpose of this study is to increase the understanding for different kinds of empowerment and how it affects the staff in the public sector.Method:The choice of method was based on the research aim. The method used to meet the objective was qualitative. The qualitative study was conducted with a hermeneutic basis, where individuals were asked to describe their experience of empowerment and how they feel affected of it. This thesis has a deductive approach, where existing theories dealing empowerment formed the basis for the design of interview substrate, which is then paired with the empirical evidence, based on this the conclusions was drawn.Result & Conclusion:What separates the different kinds of empowerment and how it affect the staff depends most of all on how the management chooses to communicate and share information with their staff.Suggestions for future research:A study regarding managers that works with different kinds of empowerment, and how that affects them, could be regarded as an interesting future research.Contribution of thesis:It shows that different kinds of empowerment affect the staff in different ways, which I made clear to the readers.Keywords:empowerment, thinking skills, relations and organizational - structure and theory.
Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Predation som selektiv kraft bakom differentiering av populationer av sötvattensgråsugga, Asellus aquaticus
Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

Japansk skräckfilm ? en kontemplativ succé?
Japanese horror film has since the late 1990: ies been extremely successful. The success could probably, at least partly, be due to the Japanese narrative style (which in my own opinion is quite suitable and effective in horror films). In what way does the Japanese narrative tradition work in matter of expression? My results point towards a narrative discrepancy between J-horror and American horror film, possibly due to the Japanese narrative tradition ? a narrative tradition under the influence of various forms of ancient Japanese theatre and general Japanese culture..
Optimering av sintrade kugghjul
Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.
Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början
This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.
Börshandlade fonder eller aktieindexfonder? : En studie som jämför avgifter och handel
Problem: For what type of investors are index funds versus exchange-traded index funds best suited?Objective: The purpose of the paper is to determine how an index fund or an exchange-traded index fund (ETF) suits different types of investors with different requirements in terms of time frame, investment size and purpose of investment. The comparison is based on fees and trade practicality. This is going to describe the advantages and disadvantages with the two different financial instruments.Method: The study is a comparative study using two methods; one of which is a case study, the other is a qualitative interview. The case study focuses on fees and is made on an exchange traded fund (XACT OMXS30) and a simple equity index fund (Erik Pensér equity enhanced index).
Balanced Scorecard identifieringens dolda dilemma
The use of balanced scorecards have spread explosively throughout the world during the last decade. This management tool have become very common in a vide spread variety of organisations on all continents. Many balanced scorecard fails though and scorecard theorists often blame the identification- and implementation process as they claim that these lay the foundation for the use of the tool. As my literature study shows, academic research on the area is rare. Particularly the effect on the implementation process from organisational dynamics and organisational structures needs further research.

Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..
Factors for success in Swedish biogas : a study based on the Swedish agricultural sector
The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.
Biogasprocessen : Bestämning av verkningsgrad
Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.
Utveckling av en LC-MS-metod för analys av gamma-hydroxibutyrat, gamma-butyrolakton, 1,4-butandiol, amfetamin och metadon
In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.
