Today?s community requires an increase in food production. Animals are today bred so that they produce more than their ancestors did. Production has been the most important and breeds with the highest production levels have therefore become popular. Many of the old local breeds have become extinct or are about to become extinct because of this trend.
Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell
An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.
Kim Jong Il - Docka eller dockmakare?
This paper has bearing on the subject of foreign policy analysis and decision-making,but is nonetheless important to peace and conflict studies due to its emphasis onnuclear weapons and deterrence.I have constructed a theoretical framework for the analysis of foreign policydecision-making that I set out to test on a crucial case. The framework iscrosscutting, and takes into consideration four levels of analysis: the system-,regional-, state-, and individual level. It is centred on a key decision maker, andapplies a cognitive approach for determining his or hers belief system through whichthe inputs from the other levels are filtered in order for the decision maker toconstruct a perception of reality, from which the decision is then formulated within.The framework is applied to North Korean and its leader Kim Jong Il. It sets outto explain his behaviour in the matter of their claimed nuclear weapons program, andhis decision to conduct a nuclear weapons-test, getting inside his head trying to figureout why he chose to do it and for what reasons.The conclusion indicates that the basic structure of the framework and its generalapplicability is sound, but that it needs further testing in order to make it perfectly solid..
Optimering av indunstningsprocess
The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.
Användbarhetsutvärdering av det lätta sandwichmaterialet Hybrix för bilkarossapplikationer
This M.Sc. thesis is a material application evaluation commissioned by the advanced body engineering department at SAAB Automobile AB. The purpose of the thesis is to evaluate implementation of the innovative sandwich design material Hybrix into an automobile body. Today the most commonly material used in the body is galvanized steel sheets and by shifting material to Hybrix several problematic issues have to be dealt with. Hybrix is an innovative sandwich sheet that inherits thin stainless steel face sheets and a stainless steel fibrous core.
Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows
When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of
added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups
resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate
(P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.
När de blir vi: institutioner, governance och förändring i Öresundskomiteen
In January 2007 the Öresund committy changed its statutes to become a more politically oriented lobby organization. This change can be interpreted as one part of a continuously evolving process where the Öresund region is emancipating itself from the national states in a multi-level European environment. By focusing on this latest development the thesis puts forward the importance of political institutions, as well as politicians and civil servants as actors in them, as crucial factors in the process where the region is gaining political power. The thesis shows how the political cross-border cooperation in the Öresund region is being institutionalized which affects its power relations to other levels in the multi-level system, predominantly the national states. In other words, there is a connection between power and institutionalization.The Öresund committee has by gaining better access to policymaking agendas on the national levels proven that the organizational change has already started to bear fruit.
Musikvärldens karta och kompass : En designstudie om hur musik kan åtkomliggöras digitalt med minskade krav på musikkulturell förkunskap
Syftet med detta examensarbete var att kommunikativt sänka kraven på musikkulturell förkunskap vid interaktion med det digitala musikarkivet Every Noise At Once. Studien tog stöd i teorier inom kognitiv semantik och teknisk kommunikation.De metoder som användes var omvärldsanalys, expertintervjuer och receptionsanalys. Längs arbetets gång formades en hypotes som sedan prövades genom empirisk datainsamling och analys av denna.Resultatet antydde att vi förstår musik, och gör oss språkligt förstådda om musik, via taktila och visuella metaforer. Detta resultat guidade sedan gestaltningen av en prototyp där utvalda akustiska attribut översattes till liknelser med taktil och visuell koppling. .
Venezuela under Hugo Chávez - en mätning av demokrati
The present state of politics in contemporary Venezuela portrays a country of polarization, a chase for power and accusations of authoritarian and even undemocratic rule. The purpose of this bachelor thesis is to examine the democracy in Venezuela, in order to clarify the sometimes vauge perception of the political situation. By applying the theories of polyarchical democracy put forth by Robert Dahl, one of the most highly regarded theorists on the subject, accordingly the discussion will therefore follow a theoretical framework. Dahl requires seven nstitutions to be guaranteed in a democracy, amongst them the possibility to vote, run for public office and the practise of freedom of speech. Measuring Dahl's levels of institutions in Venezuela, it is made clear that the level of democracy vary in different areas.
Stommaterial för villor - trä eller betong?
We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
Cirkulationsplatsers inverkan på vägtrafikbuller
I dagens samhälle är runt två miljoner svenskar störda av trafikbuller, samtidigt som bilismen och vägtransporterna ökar. För att få en säkrare trafikmiljö med ett jämnare körsätt är det populärt att bygga om vanliga korsningar till cirkulationsplatser.Denna rapport fokuserar på vad som händer med bullernivåerna då trafiken passerar en cirkulationsplats. Undersökningarna har genomförts genom att beräknade bullernivåer jämförts med uppmätta värden från olika cirkulationsplatser. Arbetet inleds med en litteraturstudie om ljud- och bullerfrågor.Bullermätningar utfördes vid totalt åtta olika cirkulationsplatser, där både ekvivalentnivåer och maxvärden samlades in. Därefter beräknades medelvärden av dessa.
Prismodeller för Facilities Management-tjänster
A study has been conducted on how organizations in Sweden administer costs of facilities management services internally. There are three main theoretical methods for administering costs. In the first method, costs are maintained on a central level; in the second method, costs are allocated and in the third method, internal transfer pricing is used. The aim of the study is to identify which methods are applied in practice, to evaluate whether the methods fulfill their intended purposes and to study the relationship between the methods used and the cost level of facilites management services. In practice, a large diversity of methods are used for facilities management costs.

När ska dieselelektrisk framdrift av fartyg väljas?
Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise on board. However, there are applications where diesel electric propulsion is not profitable. Large ocean going ships? profitability is much depending on fuel costs and the diesel electric alternative cannot compete on long journeys with large low speed engines.This thesis will treat the aspects of choosing between a diesel electric system and a classic mechanical propulsion system.
