An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

The consumption levels in Sweden, Denmark, Finland and Norway have been rising fo r the last decade. Even after the financial crisis of 2008, consumption levels continued their upward trend, regardless of the recession. The explanation seems to be, at least partly, that households tends to increase their debt ratio in order to continue the same standard of living as before in terms of consumption. It is clear, based of our results, that there is a connection between increased consumption and debt ratio for households. And the consequences of allowing loans to finance a sustained or increasing consumption may ultimately be difficult to manage.

From interviews with biology teachers and pupils, some important factors are presented that motivates and interests pupils in biology. Some of these are varied education, commitment of the teacher, narrative skill and individually reachable goals. Other important factors are practical application and connection to daily life, as well as actuality of the subject and pupils experience of the use of learning.Circumstance around teacher and pupils will influence which factors that has the most impact. It´s up to each teacher to make a decision which factors to be used based on his or her own qualities and depending on the group they will teach.Teachers and pupils agreed about factors that will cause an interesting lesson. The pupils emphasize that variation is the most important factor.

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables.

This paper investigates the relations between the fantasy genre and the phenomena of escapism. It also delves into the factors which motivates consumption of various fantasy mediums. This is done through interviews with six different fantasy-consumers, along with two observations; of which one is performed at a science fiction convention and the other at a table-top role playing game. The study resulted in a basic understanding of escapism ? it is not limited to the fantasy genre, and fantasy consumers do not deny that fantasy is a form of escapism.

The purpose of this study was to examine two medium-sized municipalities are working to people with intellectual disabilities the opportunity to go from daily activities to a paid employment in the regular labor. Work is seen as a civil right and is a measure of participa-tion in society. The Swedish government believes that the work must be available to all that includes people with intellectual disabilities. Even so, daily activities, the contribution of LSS is increases the most. The daily activities will offer incentives, development, and community and shall contribute to people get access to work or studies.

Our digital society encompasses nowadays different channels, which includes social media where many users consider it as a platform where they can fetch news or exchange news and information. This leads to a large spread of news exchange in a very fast speed, which involves the global users within social media to be a part of this social interaction. This study is focused on how Twitter affects the usage of the user?s news consumption. By reaching out to our specific target audience, which includes Twitter users in Sweden, we made a web based survey with a content of relevant questions.

The presence of nostalgic emotions during consumption is often seen as something purely positive to a product. To evoke these emotions has become a very common tool in marketing and advertising. Paradoxically very few studies have focused on the effects of nostalgia. The purpose of the thesis has been to understand how the presence of nostalgic emotions during consumption effect consumers. The research model used is a quantitative study with testing of hypotheses generated from theory.

Swedish consumption habits led to a discourse on consumption needs of the general public during the first half of the 20th century, involving primarily several institutions, but also a variety of popular movement organizations, among which we find Kooperativa Förbundet. In this discourse, ascetic consumption and a rationalized outlook on consumption were idealized, as the Swedes needed to be economical not to live beyond their means. The objective of this study is to investigate the ideals this type of discourse conveys throughout the latter half of the 20th century. This will be achieved by investigating selected editions of the cookbook ?Vår Kokbok? published by Kooperativa Förbundet.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.
