Privata skogsägares attityder och anpassningar till klimatförändringar : En fallstudie i Kronobergs län

Conditions for Swedish forestry are expected to change in the future due to the climate. Among other things, increased production is expected in a warmer climate, mainly because of a longer growing season. With the changing climate risk of damage by such as insects, fungi and storms are expected to increase. Hence, it is of highest importance for private forest owners to spread these risks in the way they cultivate their forest. In this study a qualitative method was used to examine ten private forest owners with forest properties within Kronoberg county, Sweden in their attitudes and actions to prepare in terms of climate change and if they have been affected by the climate change debate in their forest decisions.

Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter

A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.

The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

Återväxt av blåbär (Vaccinium myrtillus L.) efter ångbehandling : orsaker till effektiv kontroll

Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.

Impleamini agnicione voluntatis Dei : En predikan ur Skoklosterhandskriften

This essay describes my work as a director in a specialized orientation within psychodrama, surrealistic psychodrama. Using the language and performance techniques of theater and under the guidance of a director, psychodrama creates an improvised narrative or story. The essay describes several dramas I have directed, reflecting on my actions and choices as a director and group leader. I examine whether my working method has allowed me to be spontaneous and creative, which I believe the example of "The dangerous bear" demonstrates. The process enabled me to establish trust and receptivity so that a newly constituted group dared to investigate conflicts in symbolic ways associated with illness and death.

En jämförelse ur energisynpunkt mellan roterande värmeväxlare och frånluftsvärmepump i universitetsbyggnad

För att tillgodose den studerande KTH byggnadens framtida krav kommer det befintliga ventilationssystemet att bytas ut. Två olika möjliga värmeåtervinningssystem har jämförts ur fjärrvärmebehovssynpunkt. Det befintliga systemet med vattenburen batterivärmeväxlare har en låg värmeåtervinningsgrad och Akademiska Hus önskar system med högre värmeåtervinning. I byggnaden har roterande värmeväxlare och frånluftsvärmepump för uppvärmning av tilluften jämförts. Då värmeåtervinning från dessa system inte är tillräckligt kommer fjärrvärme att används.I beräkningarna jämförs fem roterande värmeväxlare mot varierande antal frånluftsvärmepumpen.

Service i privat sektor ? En kvalitativ studie om servicearbetarens upplevelse av sitt jobb

The aim of this qualitative study of service work in the private sector is to examine how the service worker experiences his/her work. There are three dimensions of the service workers experience in focus, and they are the base of my formulation of questions. The first dimension refers to how the service worker experiences the emotional labor demands from the employer. The second dimension concerns the relation between service worker and customer, from the view of the service worker. The third dimension problematizes how service workers experience efficiency.I have interviewed three call center customer workers and two hotel receptionists, using semi-structured interview technique.

Investmentbolag eller sverigefonder som Sparform? : En analys om vilken som är den bästa sparformen med avseende på risk och avkastning åren 2002-2010

There are various investments to suit different investors, what affects the investor is the risk he/she takes with the investment and also the awareness  the investor has. According to different theories a higher risk gives even a higher yield to compensate for the extra risk the investor takes.In this paper, we discuss and compare two different forms of savings, Swedish closed-end funds and Swedish mutual funds to examine what alternative that generates highest returns in relation to the risk.To help, we use different evaluation measures that adjusts the different investments risk so that you can compare how well the investments have performed regardless of the risk they have. This will give us an answer about what investment form that have performed the best between 2002.01.01-20010.12.31. Five Sweden mutual funds and five closed-end funds have been selected to participate in the survey.To evaluate this, it is primarily quantitative data, analyzed in the evaluation measures. The results obtained in the survey show that Swedish closed-end funds have performed far better during the selected time period.

Trafikverkets effektstyrningssystem - EFS 132 kV : Bidraget till minskade förluster

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.
