Framtidens Hus

The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..

Systemanalys av skogsbränsletransporter :

At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.

Torkning av vallfrö :

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

Företags motiv till finansiering med realränteobligationer

The long-term external financing of a corporation is satisfied through the bond market where issues of index-linked bonds, which are discussed in this thesis, is one alternative. (Finnerty&Emery 2001) An index- linked bond is a debt instrument where the investor is guaranteed the principal and premium amount in real terms. As the bonds cash flows are indexed to the inflation this implies that the issuer of an index-linked bond assumes an inflation risk. Purpose: The purpose of this thesis is to describe and examine corporate motives for choosing index-linked bonds as way of financing their business. Realization: Primary data was collected through interviews with corporate issuers of non-swapped index-linked bonds.

Motivation att använda styrketräningsappar: en kvalitativ undersökning av motivationsfaktorer bland ungdomar

AbstractWorking with child and youth welfare is one of the most difficult challenges a social worker might face in the field of social work. Those who work with child and youth welfare are more exposed to stress and burnout than other comparable human service occupations. Research links the prevalence of stress and burnout to several key variables, such as demographics, working conditions and personality factors. In contrast, even though social workers in this field face many negative work-related problems they report a high job satisfaction. The aim of this study is to examine how uplifting and straining experiences affect social workers, who work with child and youth welfare, through the use of The Critical Incident Technique and interviews.

Drivet bakom klivet - en studie av drivkrafterna bakom steget från näringsliv till ideell sektor

The Swedish nonprofit sector is experiencing a sectoral change, moving closer to the corporate sector to become more commercialized. The recruitment of leaders with corporate experience constitutes one of the factors influencing this development. Hence, to create an understanding of this sectoral change, the thesis aims to investigate the motivational forces underlying the leaders' decisions to work within the nonprofit sector. Additionally, the thesis seeks an understanding of why the leaders' decisions were made later in their careers. Through conducting qualitative interviews with leaders representing top management of six humanitarian organizations in Sweden, the study finds that nonprofit leaders with corporate background, analogous to volunteers and employees, are motivated by a sense of relatedness to the vision of the organization.

?Det är trevligt att bläddra?? : om anledningar till varför man läser papperstidningar

Purpose/Aim: To investigate why people in the age group of 30-40 subscribe to the traditional morning newspaper even though they can get the same information at a much lower cost from for example TV, the internet or the free daily papers. The aim is to also look at possible future alternatives to the traditional morning newspaper.Material/Method: Focus group interviews were used to gather the empirical material. These consisted of a total number of twelve people, divided into three groups. The results from the focus group interviews were analysed with help from established uses & gratifications theories and two diffusion theories.Main results: This study shows that people read the traditional morning newspaper to get a good mixture of entertainment and local, national and global news. It is relaxing to read the newpaper on paper compared to reading it on the internet, mainly because you get a good overview which makes it a lot easier to find exactly want you want to read.

Ordning & Åtgärder : En undersökning av lärares arbete med att skapa ordning i klassrummet

In this essay the author has studied teachers work with order and measure in the classroom. The empirical survey method has been collected through interviews of focus groups from three different schools located in three different municipalities consisting nine participating teachers in total. The aim with the study is to understand the complexity of creating order in the classrooms by the existing means of control and finding an answer to teachers reasoning around the two articles ?We need to inform how the situation are in school when it is at its worst? and ?Stop defaming school?.The analysis is structured by my questions at issue which are;How does the teachers' work with the means of control which exists in the curriculum to maintain the order in the classroom; how does the teachers concure to the concept of order in relation to the media and the political statements that exists regarding the order issues at school; are there any alternative measures and methods to maintain the order in the classroom.The result shows a unanimous view about what order is among the teachers. Order is a necessity for the pupils to have a good studying climate.

Krigets diskurs och vägar till (positiv) fred: En idé- och diskursanalys av Belfastavtalet och Annanplanen med diskursiv konflikttransformation som normativ utgångspunkt

Protracted social conflicts, as those in Cyprus and Northern Ireland, are based on deep rooted perceptions of identity and definitions of "the other". According to the theory of discursive conflict transformation, war is primarily a social phenomenon, which is legitimated by a discourse of identity defined in terms of exclusionist boundaries and structural ideas of the social relations in society. In order to develop positive peace, the discourse of violence has to be challenged and the discursive structures that enable war have to transform into a counterdiscourse of inclusion and individuality. For the purpose of making a critical peace analysis, I have, with the assistance of established conflict theories, analysed the basic ideas behind the the Annan Plan and the Belfast Agreement and thus been able to interpret to what extent they may foster positive peace. I argue, that in order to provide basic needs on a group basis, power sharing arrangement, based on ethnicity or religion, exacerbates division rather than ameliorating it.

Den tredje vägens ufologi : En studie av vetenskapligt gränsdragningsarbete inom Riksorganisationen UFO-Sverige

The following essay or thesis is a study over scientific endeavors in the fringe. It is a study of Riksorganisationen UFO-Sverige, whose proponents aim to make the UFO phenomenon (or phenomena) a subject of scientific scrutiny. To achieve this, the ufologists first have to redefine common concepts of ufology as pseudo science or religion, mainly by challenging definitions given by scientific sceptics on the one hand, and proponents of conspiracy theories or the new age environment on the other. Thus UFO-Sverige seeks to construct an alternative scientific identity in contrast to adversaries on both sides, each unwilling to give the UFO phenomenon any further examination. Following the work of Tomas Gieryn's sociological grip on questions of epistemology, especially concerning the social boundaries of science from other cultural categories through what has been labelled as epistemic boundary work, during which proponents of a particular field aim to achieve epistemic authority and thus the legitimate right to define what is and what is not science, I seek to analyze how questions of science and legitimacy are actualized in an intellectual environment or culture not broadly accepted as scientific.

I ljugen, I ljugen, jag är ej en kvinna! : En queerteoretisk analys av huvudkaraktären Tinto och maskeradmotivet i C.J.L. Almqvists Drottningens juvelsmycke.

The purpose of this paper is to do an analysis of the characters and the theater/masquerade motif in C.J.L. Almqvist?s Drottningens juvelsmycke (The Queen?s Diadem), based on queer theory, by using Judith Butlers?s Gender Trouble. As an alternative to the Swedish, gender determined, feminine pronoun ?hon?, which has been used by earlier critics concerning the main character of the book, ?hen? is proposed.

Beräkningsmodell för massbalanser för Slottshagens reningsverk

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..
