Markanvändning och ekosystemtjänster i en gradient från borealt till alpint landskap ? Vilhelmina Model Forest

Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.

Besparingar inom Barn- och utbildningsnämnden : en jämförande studie mellan Landskrona och Kristianstad kommun

Title: Besparingar inom Barn- och utbildningsnämnden.Seminar date: 29th of May 2009Course: Degree thesis in Business Administration, bachelor thesisAuthors: Amela Smajlovic and Sten SundfeltAdvisor: Leif HolmbergPurpose: Our purpose is to explain the cost-saving process that many municipality organisations face because of the global financial crisis.Limitations: We have limited our study to the municipality of Landskrona and Kristianstad.Method: Our study has a qualitative approach. By using open interviews we have been able to get an open dialog with our respondents.Theory: We have compared with different theories, such as Rombach?s budget-theory and Wildavsky?s role theory.Empirics: The material is based on interviews and conversations with key figures in different levels of the organisations in Landskrona and Kristianstad.Conclusions: The success of a cost-saving process depends on the engagement, awareness and how inclined to changes the persons in the organisations are. Has everybody the willingness to take responsibility fore the organisation and the changes that the surrounding world claims?.

Vem hålls ansvarig? : En studie av de förändrade förutsättningarna för ansvarsutkrävande med avseende på svensk krigsmaterielexport

This thesis explores the changing prerequisites for accountability in terms of Swedish arms export. The study aims to uncover what has happened with the conditions for accountability in Sweden since the responsibility for export control was transferred from the government to the public administration. By investigating how the term ?accountability? has been used in the literature of democratic theory, an abstract ideal model is being created.  Comparing the changed structural arrangements, with each other and the ideal model, it is concluded that the prerequisites for accountability now seems to be in a worse state than they were before..

Mätning av inköpsmognadsgrad: - en första ansats

This paper explores a model for self-assessment of purchasing maturity in large companies. The author adapts contemporary purchasing theory and further enhances existing tools and procedures to create a survey based instrument for maturity measurementThe paper also explores potential methodological challenges associated with conducting a more extensive study of purchasing maturity via the proposed model. A preliminary study is made and the learnings discussed.The preliminary findings of the survey indicate that the purchasing maturity varies with industry. The purchasing function average score was found to be 3,4 out of 6 with samples spread across the whole spectra ? agreeing with previous theories stating that the purchasing maturity is highly varied between different industries..

Studie samt reglering av luft- och massflöde för en barkpanna

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

Varför läxor? : En studie om några mellanstadielärares tankar om och syfte med läxor

The aim of my study is to get an idea of how some teachers use homework, what they consider a good homework is, and what considerations they take to the students' home circumstances. I have made a qualitative interview study with four middle school teachers. The results of my study show that teachers can flip the classroom and use so-called preparatory tasks. The time saving aspect is a strong reason they choose that model. That students are able to practice their own responsibility and perform meaningful homework seems to also be in focus, but the biggest reason they use flipped classrooms seems to be because it is a more equivalent homework then traditional homework, and that students and their guardians also appreciate the flipped classroom model as they become more involved in their children's schoolwork..

Analys och modellering av ljusbåglängdsregleringen i pulsad MIG/MAG-svetsning

This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.

Folkbibliotek och TV-spelande ungdomar en studie i bibliotekariers attityder och värderingar när det gäller ett nytt medium på biblioteket

The aim of this Masters thesis is to examine librarians attitudes and values when it comes to the question if a new media, video games, should be introduced at the library or not. Video games are here seen as media primarily for youths. In our study we also wanted to study the discussions of quality and purchase, when computer games were introduced at the library. In order to answer our questions we conducted nine interviews with librarians working with children and youths, in eight libraries. By analysing their statements, using Maj Klassons theory where she defines the librarians role in three different strategies, we could demonstrate how the librarians reason when it comes to video and computer games, youths, quality and purchase.

Volymsrapportering vid terrängtransport av virke

This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU. The work was an assignment from the forest owners? association Mellanskog. The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards. This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.

Det handlar om träd. Ett utforskande mönsterprojekt för textil

This is a pattern project for textiles, with main purpose to develop and challenge my design process and to experiment with a mix of different printing techniques. The goal of the project was to create three textile individuals as representatives of my experiments, inspired by natural surfaces.The world of fashion have been an inspiration and has been the model for these textiles, with its powerful and playful patterns. With the world of fashion as a model, I also chose to work with the materials habotai silk and silk velvet. The qualities of these materials has also been influential in my design language.The work has been very focused on experiementation and exploration, and resulted in three printed fabrics that I have chosen to call Björkalm, Lindstam and Lavbädd..

"Du får titta i min bok!" : Fem förskolelärares tankar om barnbibliotekens funktion i barns tidiga läs- och skrivförmåga.

This study aims to examine preschool teachers' thoughts about the child libraries functions. The purpose is to highlight preschool children's early read and writing skills, before they even can read and write, which is a theory called emergent literacy.This is made by conducting five qualitative interviews, with the intention to investigate how the preschool teachers think about the cooperation and the function of the child library, partly for their own work with the children and partly for their organization. By using a tablechart which shows each preschool teachers mostly common thoughts in the interview and by using a model based upon Harrysson and Joelsson (2006) model, which shows the functions of the public library in the society. The results of the study are presented in the four categories of the model which are; to borrow, to learn, to ask and to find, to reside. These are functions that the preschool teachers see with the library, for their work with the childrens' early literacy.

Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL

This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.

Identifiering av röjningsbestånd med hjälp av flygburen laserskanning

Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.

Avgörande faktorer vid affärsutbyten med Polen : en flerfallsstudie inom miljösektorn

Länsförsäkringar in Värmland, Sweden, had during the year 2003 a total level of 6.1 percent of people on the sick-list, which was higher than average in the business (4,5%) and for salaried employees in the private sector (3,3%). The average age of those put on sick-list was 47 years, whish is four years higher than the average for the whole LF-group. The cost for the total amount of people being on sick-list at LF-company (6,1%) was estimated to 1 500 kkr, according to a calculation model coming from Försäkringskassan. For every percent the sick level could be reduced, the company would save 239 kkr. To map out the state of health of each and every collaborator in LF, the company offered all employees to make a health profile at the company's health service, Clarahälsan AB.

Utbredning av markvibrationer och stomljud från järnväg : Undersökning och anpassning av beräkningsmodell

The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from railways..
