The effect of additional nitrate and sulfur in the diet on the methane production in cattle
A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.
Behov av managementverktyg i mjölkproduktionen :
For the company to work well, it is necessary with a good economy, a high qualitative production and a well working system concerning the environment: the whole cycle on the farm needs to be working. At the same time, debaters about the environmental impacts are also requiring higher demands for the dairy farmers and therefore also the management programs. Management programs for feed evaluation calculations have been more developed over the years. Big amounts have been invested in the new feeding system with NorFor, but no one seems to have asked the dairy farmers what they themselves want to spend their money on, and what they need help with. For the dairy farmers it is necessary that the whole company is controlled in the right way, and much more than just feed evaluation is included in this.

E.ON:s transformatorflöde - en studie av återanvändningen av transformatorer i projekt krafttag
Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.
DESIGN AV ALUTON 38? FRAKTBÅT FÖR KUSTNÄRA TRANSPORTER
This master thesis is about designing and dimensioning a boat for transport of caravan, car, trailer or ATV. Buoyancy and stability are important properties as the pontoonboat should also be able to serve as a workboat. Many of the vessels on the market today that is being used for similar purpose are stable enough, but their hull is often similar with barges and thus too slow. This work has been to construct a boat that has good stability but also has a hull that enables it to move faster, is more maneuverable and having a more attracting design than today?s barges.
Utformning av en arbetsmodell för införande av lean inom sjukvården : En fallstudie på Gävle sjukhus
Att införa lean principer inom sjukvården är ett relativt nytt område. Landstinget i Gävleborg och Gävle sjukhus är intresserade av att korta ner sina vårdköer med hjälp av logistiska metoder och lean production principer. Detta på grund av att vårdköerna på bland annat urologmottagningen på Gävle sjukhus bara växer. Lean production är ett koncept som ursprungligen härstammar från bilindustrin i Japan och innebär att man strävar efter att göra mer med mindre. På svenska kan lean production översättas till resurssnål produktion och arbetet med lean innefattar principer som kunden i fokus, teamarbete och ständiga förbättringar.Syftet med examensarbetet är att ta fram en arbetsmodell för införande av lean principer inom sjukvården, då vårdköerna idag är långa och någon form av förändring är nödvändig.

Analys och förbättringsförslag för riktkopplardesign
Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.
Pottaskeframställning och tjärbränning i Femsjö socken från år 1700 till 1900 :
Femsjö is a small parish situated in Hylte municipality, Växjö diocese. The parish has a total area of 8230 ha of which 5000 ha are covered with forest. There have not been any large industries in the parish offering work opportunities for the inhabitants, so they have had to generate income from their land and the forest. Instead of going to the bank to get a bank loan the people of Femsjö parish went out in to the forest and harvested trees for timber and extra cash revenue. Production of pine tar and potash were two other ways that the residents of Femsjö parish could earn extra money for the household in order to keep starvation away.

Nord Pools systempris - en studie av prispåverkande faktorer
The intention of this thesis is, from a basic statistical viewpoint, to capture the relationship between the price of electricity and a sample of factors influencing the price. The thesis also aims at investigating whether knowledge about the relationship is useful when investing on Nord Pool. Tested factors are temperature, import, price of emission rights as well as a number of hydrological factors. The investigated period stretches from year 2000 until week 32 year 2007. The relevance of each factor was also evaluated yearly as well as for shorter periods in order to get a more comprehensive view of the relationship.
Empire and Multitude - Den globala klassanalysens nya subjekt?
This essay contains a comparative analysis of Erik Olin Wrights Marxist class analysis and Michael Hardt and Antonio Negris post-Marxist class analysis as presented in their books ?Empire? and ?Multitude: War and democracy in the age of Empire?. I discuss the shift in analytical focus from state level to global level that Hardt and Negri's analysis represent and the ensuing relevance of this for contemporary class analysis. The essay also address the challenge and implications posed to class analysis by the ever increasing economic globalization, from a material production to an ever growing immaterial service economy and the decrease in state power in controlling capital and labor movement. I propose that analytical understanding of class conflict help us to a better understanding of the mechanisms and dynamics that generate social and economical inequalities and that an updated Marxist class analysis still have much to contribute to our understanding to how these issues not only shape our society but also our capacity to counteract them..
Hon tar vad man vill ha : en studie av sexuella maktrelationer i samtida relationsromaner
The aim of this study is to analyse the sexual power relations in contemporary urban novels of Swedish female writers.I have identified a discourse in these novels as a heteronormative matrix which power is ruled by norms and assumptions about normality in both the heterosexual and lesbian stories. For this purpose I have related to Ivar B. Neumanns theory that individuals always find a way to confront the discourse by three different strategies. These strategies are used in my study as tools to organise these novels, because it is possible to see that the protagonists find at least one of these strategy?s to her protest.The first strategy I studied was the docile.

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.
