Samkörning mellan värmepumpar och fjärrvärme : Bostadsrättsföreningen Bogården
This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.
Blandfoder i automatiska mjölkningssystem
A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way.
The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

Odlingsstrategier på organogena jordar : en studie om beslutsfattande bland KRAV-anslutna lantbrukare
This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.
Svenska hushålls vedarbete : en fallstudie i Umeåregionen
In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood.
The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.
"Lite snyggare, lite mer partyaktiga, lite mer Paradise" : En kritisk diskursanalys av kön och sexualitet i Paradise Hotel
The purpose of this thesis is to examine how power structures concerning gender and sexuality emerge through the use of language in the Swedish reality show Paradise Hotel. Of particular interest is the representation of heterosexual relations in the show. Because of its interest in the relationship between power, gender and sexuality, the thesis is based on theories from gender and discourse studies. The specific theories referred to are Michel Foucault?s understanding of power, stereotypes according to Stuart Hall, Yvonne Hirdman?s gender system and contract theory, Judith Butler?s heterosexual matrix and R.W.

Att definiera omsorgsbrist : En kvalitativ studie om socialsekreterares tolkningar av 2 § LVU utifrån intersektionalitet och makt
This study regards the Care of Young Persons Act, LVU, and the 2 § that focus on parent inability to care for their children. The assessment of parent ability to care for their children is performed by social workers in different municipalities. The law leaves room for interpretation concerning how to assess parent ability and therefore we found it interesting to study how social workers interpret 2 § LVU. The study?s aim was also to seek an understanding of how different categories, like gender, race, class and physical and psychical ability of the parents affect the assessment of their parenting ability, with a intersectional perspective.
Beräkning av värmeförluster och energieffektivisering av elbussar
The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå. The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.
Nekande tvångsmakt i Operation Unified Protector
There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.
Kampen om dagordningen : Kan media anses vara en enskild politisk aktör
Abstract Essay in political science, C-level, by Patrik Larsson, autumn semester 2007.Tutor: Susan Marton The battle over the agenda-Can media be regarded as an individual political actor? The purpose of this essay is to study to what extent media can be regarded to function as an individual political actor. In other words, do the media have more power over the political agenda than the politicians and do the media influence how the politicians make their decisions. This research is a case study and to be able to complete the intention of this study I have used Maxwell McCombs and Donald Shaws theory, the agenda-setting theory. From this theory I have used four aspects to analyse my material which has consisted of editorials from a Swedish newspaper, interpellations and debates that belong to the interpellations. The aspect I have worked with are, how the problem is defined, who is responsible for the problem, what values and which solutions are expressed. I have used a qualitative text analysis as my methodological approach which means that the results of my study are my interpretation of the material. My conclusions are that the media in this case shouldn?t be regarded as an individual political actor because there is no tendency that shows that the media has influenced the government in their decisions concerning the real-estate tax.
Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler
This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.
Kyla i Nyköping och Motala : Kartläggning av kylapotential för Vattenfall Värm
The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.
En diskursreglerad v?rld: Makt, kunskap och agens i Mark Lawrence? The Book That Wouldn?t Burn
Historically the library has owned more than silent, book-filled halls; it has been a center for learning and ideas, a source of both freedom and oppression, in other words, a medium for knowledge, truth, and power. Cultures have been divided into powerful and powerless through access to the library's content; those who have - and those who do not have - access to information determine which voices are heard and which are ignored, thus determining the outcome of the future.
This thesis investigates how The Book That Wouldn't Burn by Mark Lawrence portrays the relationship between knowledge and power using Michel Foucault's discourse theory. More specifically, how this relationship is manifested through the structures and norms of society, and how the library as a place and institution serves as the means by which this relationship plays out. An established classic like Fahrenheit 451 by Ray Bradbury is placed as a contrasting reference point to help deepen its thematic message of information control and cencurship. Furthermore, the agency of one of the main characters is also examined in the light of Anthony Giddens' stratification model, as an actor with the potential to move beyond the confines of the power structure.
The analysis demonstrate how knowledge, truth, and power remain continuously thematically relevant within literature, and how the reality of our time may be better understood through literary contributions.
Dokumentärfilmproduktion ur ett ljudtekniskt experimentellt perspektiv
This paper is a study of documentary film production with focus on the filmmakers choice and usage of sound equipment. Using professional articles and literature have first of all helped us determine a standard for the conventional use of sound equipment in documentary film. Afterwards, by analyzing our own interviews we?ve received answers on how filmmakers relate to the conventional usage and why they select equipment as they do. Thereafter, we describe a technical method which helps a filmmaker to be able to record sound for documentary film on his/her own, using simple measures without reducing quality.
