Skogs- och energibolagens attityd till förnybara drivmedel vid upphandling av transporttjänster i norra Sverige
Sweden's government is dedicated to the goal of having a vehicle fleet that is independent of fossil fuels by 2030. Achieving these goals requires, among other things, new types of fuel that give lower net emissions of carbon dioxide. The present market includes stations offering lowlevel blends of renewable fuels in conventional diesel as well as some stations offering renewable fuels only.
The purpose of this study is to survey purchasers? attitudes to the use renewable fuels in roundwood and bioenergy transport in forest- and energy companies.
The study was based on qualitative interviews through a combination of face-to-face meetings and telephone interviews with each sample group. The total number of respondents was ten (10), consisting of five (5) from forest companies and five (5) from energy companies.
Transport service purchasers were generally positive to renewable fuels and considered these necessary in the future.
Barn i familjehem: En studie, om långtidsplacerade barns fysiska och psykiska hälsa, tonårsgraviditet, skolgång samt om föäldrarnas psykiska hälsa och mortalitet, i en undersökningskommun
The main purpose of the study was to analyse the well being of children placed in foster care for at least two years, in one sample municipality. An assessment was made of how the social service admistrated and took responsibility for these children in terms of schooling, physical and mental health. To further understand the situation of the children three areas of investigation were added concerning; teenage pregnancy, the mental health and mortality of the biological parents. To receive answers to those questions a qualitative interview method was used, with structured questions to social workers working with foster care. The author also studied journal notes and child investigations to receive a more comprehensive picture.
Att kommersialisera och sa?lja en plats : en analys av resereklam, representationer och geografiska fo?resta?llningar
Pictures are often used when marketing a tourist destination. Photographs of a place, a destination, are used to convince customers and stimulate daydreaming in order to turn a potential customer into a real customer. For some people the photographic representations of a place is the only one they experience. With this in mind, it is reasonable to question how representations of places and geographical imaginations are being (re)produced when marketing a destination by using photographs. This paper aims to study how representations of place and people are used when marketing a tourist destination via travel commercial.
Värdet bakom våldtäkten : En diskursanalys av fyra rättsfall
This paper seeks to explore how victims of crime and defendants are portrayed in sexual assault cases. Lately, more and more voices have been raised in appal against values demonstrated in court decisions and we?ve seen the implementation of a new sexual assault legislation in attempt to increase people?s sexual integrity. Yet, at the same time, there is still a tremendously low amount of reported sexual assaults that go to trial and even fewer result in conviction. This paper is not an attempt to scrutinize the legal system, but to draw attention to what values are portrayed in sexual assault cases.
Val av revisionsbyrå : Vilka faktorer påverkar valet av revisionsbyrå i svenska aktiebolag?
Title: Selection of audit firm - Which factors affects the choice of audit firm in Swedish limited companies?Subject: 4FE03E ? Master thesisAuthors: Alexander Rosén & Martin KarlssonSupervisor: Magnus WillessonExaminer: Sven-Olof Yrjö CollinKey words: Audit firm, audit firm characteristics, client characteristics, limited companyBackground: In Sweden, the auditor is selected when the company has their annual general meeting. Following, the auditor?s task is to secure the quality of the financial information so the owners and other stakeholders can trust the information, which regards to the financial situation for the company and the CEO´s and board of director´s management. Since November 2010, private limited companies are free to use and have an auditor, but only if they fulfils the requirements that are regulated in ABL 2005:551.
Adaptive QoS Management in Dynamically Reconfigurable Real-Time Databases
During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.
Majsensilage - partikelstorleksfördelning och hygienisk kvalité :
Fieldstudys on 22 farms (23 silos) to study relationships
between the actual particle size of the maize silage and the theoretical length of cut. The measure of theoretical length of cut were stated by the farmers and not measured by us.
Particle size of maize silage was determined using the New Penn State Forage Particle
Separator. SLU Skara made a special sieve for us, that had larger holes than de original
sieves. The samples were shaken after instructions and then the
material was weighted. We have also been taking out samples for microbiological
analyses from the silos on 13 of the farms.
Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Varför sagostund? Sagostundsverksamheten på folkbibliotek igår och idag.
The purpose of this Masters thesis is to investigate the reasons for public libraries to have story-time today and also the reasons for story-time at the public library historically in Sweden. Why is the phenomenon of story-time still existing at public libraries today? The study is based on a questionnaire that was sent to childrens librarians in the Västra Götaland region. The material collected in this questionnaire was put together and resulted in six different categories showing the libraries purposes and thoughts of their story-time activities. The categories were: cultural heritage/tradition, joy of reading, language and imagination, library visits, storytelling and mutual experience.
Att leda p? distans och p? plats - En kvalitativ studie om chefers f?ruts?ttningar att ut?va ledarskap p? distans och p? plats
This study aims to explore managers? experiences and perceived conditions for exercising leadership in both hybrid and physical work environments. The empirical material consists of eleven semi-structured interviews and four policy documents. The sample includes eleven managers, of whom six work in a physical environment and five in a hybrid setting. The study follows an inductive approach, where the interviews were first collected and later analyzed by identifying patterns and connecting them to theories on different leadership styles, monitoring, and trust.

Giftermål och geografisk mobilitet : en studie över Västra Eneby socken under 1800- talet
Industrialisation, modernisation and urbanisation are common words used to describe an evolving community. General patterns are often linked to the meaning of the above words but can these patterns be applied to individual parishes on the agricultural countryside?The purpose of this study is to seek moving patterns and how they change during the 19th century in the parish of Västra Eneby, municipal of Kinda, Östergötland. The main thesis is that the study will show an increasing intensity of translocations over the parish border towards the end of the 19th century.The study is based on material from Västra Eneby?s church archives to establish statistical data beginning with 1809 and with a sample rate of 10 years, ending with 1909.
Mätning av partikelmassa i avgaser från en dieselmotor
This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.
Tidsåtgång i mjölkproduktion under betessäsong : inflytande av besättningsstorlek, samt mekaniserings- och automatiseringsgrad
Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.
The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation
The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours.
In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.
