Föroreningstransport i grundvatten : En modelljämförelse

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

Osäkerheter vid brandteknisk dimensionering av ventilationssystem

This masters thesis deals with smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how Uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.

"Barn uppfattar på ett sätt, fast det kan vara på ett annat" : En kvalitativ studie om socialtjänstens uppfattningar och arbete med fysiskt misshandlade barn

The aim of the study was to examine what workers in social services considers physical child abuse and in which way social services work with children who have been exposed to physical child abuse. The study also examines which interventions are available and how physically abused children assimilate these. I've interviewed four child-welfare officers and for those interviews I've used the qualitative semi-structured method. The results shows that all my respondents have different views on on the definition of physical child abuse. The result also shows that the municipality which the children belongs to plays a major role in which children can get help with their problems.

Gapet: En studie om gapet mellan leverantörer och köpare av digital skyltning

The aim of this study is to describe the market for Digital Signage in Sweden and give the reader an increased insight and understanding of the problems that suppliers and buyers of Digital Signage may encounter. The study is abductive and based on a number of qualitative interviews with representatives from potential buyers, an existing user, a supplier and a number of companies with insight into Digital Signage. Our findings show that the companies in this study have not yet reached the stage of being ready to invest in a system for Digital Signage, since the effects on for instance increased sales and potential savings on marketing communication have not yet been clearly proven. Furthermore the study shows that it is important that a supplier has a fundamental understanding of the business model of the buyer. In addition to this, service, support and IT-related issues are of great importance for the potential buyers.

Immunohistochemical evaluation of antibodies for staining of mouse spinal cord and mouse neuronal cells

The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the laboratory to the new legislation, through inventory of stored chemicals, update the list of chemicals and perform self-classifications of mixtures. The work included handling of about 650 different chemicals with varying hazard classifications and search for information in corporate websites and chemical databases. This resulted in a new and complete list of chemicals stored and used in the laboratory and, in addition, an example of how to make a self classification of a mixture.

Laboratory adjustment to the new regulation on classification, labeling and packaging of substances and mixtures.

Ett kognitivt branschperspektiv : Bemanningsbranschen

Background: The way in which corporate managers interpret, reason and evaluate Uncertainties and constant changes, and how they take advantage of their experiences and wisdom can make a big difference for the long term survival of their companies. The requirements for efficiency and flexibility have increased in many ways, especially concerning the workforce needed and its degree of competency. In Sweden, employee recruiting industry has grown concurrently with the changes in the Swedish economy. Purpose: The purpose is to better understand the recruiting industry by performing a theoretical evaluation from a cognitive perspective. Delimitation: We intended to study the cognitive characteristics of the Swedish recruitment industry.

En studie kring processen att som IT-konsult skifta affärsmodell genom försäljning av en standardiserad lösning.

Due to increasing international competition and new technology IT-consultants has been forced to oversee their business models lately. The main purpose of this study is to investigate the process and consequences of a shift in business model for a consultant by using a methodology based on action research. The empirical foundation consists of a field study with observations, notes, interviews and business related documents. The case describes a consultant?s process of shifting business model from profits based on man-hours to selling a standardized system.

En simuleringsmiljö för distribuerad navigering

This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and Uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.

Incorporating the future - a study of three companies? internalisation of future trends forecasting and scenario planning.

Purpose:The purpose of this thesis is: to determine key success factors for an organisation?s internal process of internalising future trends forecasting. Methodology:A qualitative approach has been chosen by examining three different companies (Electrolux, H&M and, Sony Ericsson) through interviews and other data. The empirical material have been analysed by using valid theory as a platform from where the analysis can be performed. This has created a conceptual analysis that enables the use of the conclusions in other similar companies.

Läsarens interaktion med texten : en studie av hur läsarens uppfattning av texten påverkar meningsskapandet i absurdistisk dramatik

This essay examines how the meaning of an absurd play may be affected by how the reader understands the text. To address this problem I have turned to Wolfgang Isers theory of reception. Primarily I have taken on that the creation of meaning comes about when the reader fills in blanks in the text. I have also used Martin Esslins work on the theater of the absurd. I have mainly studied his research on Harold Pinter.

Funktionsupphandling av solelanläggningar

This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.

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.

Climate adaption within agriculture is important to reduce the risks that agricultures are exposed to because of climate change.  Through climate adaption you can improve the positive effects and take advantage of them optimally. How the climate change affects agricultures varies depending on regions and societies. The purposes of the study are to examine how different actors experience the impacts of climate change on the agriculture in Värmland.

Den anglosaxiska trusten : En analys av en förmånstagares beskattningskonsekvenser av trustegendom som utgörs av aktier

The Anglo-Saxon trust is not a new phenomenon, but existed as early as in the Middle Ages. The concept is customary among common-law countries, such as England the US,but unfamiliar to civil-law countries like Sweden. The person who creates the trust is called a settlor, the one who holds and administer the property is a trustee and the person who benefits from the settlement is called a beneficiary.In Sweden there is no legislation of how the trust ought to be assessed, but the need to understand it has probably increased with the internationalization.The Swedish Supreme Administrative Court has had a few opportunities to elucidate some of the Uncertainties regarding trusts, but chose to abstain. With this The Swedish Tax Panel has very limited guidance from the court when they receive an application of an advance notice.A trust is not a legal entity nor a tax subject. This differs the trust from a foundation and they can not be placed on an equality from a Swedish tax perspective.In an advance notice, 2010-03-23 (dnr 103-09/D) om Inkomstskatt: Inkomst av tjänst ? värdepappersförmån, the Swedish Tax Panel equalizes the trust property with shares when determining how to tax the assets.
