Delta X : Utveckling av värmeväxlare
Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose Origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..
Trädgårdsstaden : från historisk idé till dagsaktuell verklighet
The aim of this study has been to make clear the conception of ?The Garden City?, and also to investigate why and how the garden city has come to be a more frequent and attractive form of settlement in our Swedish community. The essay is supported by a literature study about the garden city from its beginning (1890?s) to present time. To make a distinct explanation of the garden cities progress over time, I have studied the idea behind two garden cities of today, Tullinge and Vistabergs garden city.
Optiska illusioner inom landskapsarkitekturen
My thesis is a combination of theory and practice, where theory is meant to create a context and a background for my interpretation proposal. I wanted to ?access? the ideas that are always in the background of the reasoning which underlies both planning in a larger scale, and the design of a place. I wanted to make a ?work of ideas.? In the process of shaping the proposal, I wanted to be deleted from the site itself.
Svenska mjölkbönder, snart ett minne blott? - Markbygdens mjölkbönder i tankar om mjölkproduktionens nuvarande situation och framtidsutsikter
Major changes within the agricultural politics today have forced the dairy production to scaleup, in order to compete on a global market. This has resulted in a reduction in the number ofsmaller dairy farms in Sweden, from about 40000 to just over 4000 over the last 30 years. Thepurpose of this study Svenska mjölkbönder, snart ett minne blott? ? Markbygdensmjölkbönder i tankar om mjölkproduktionens nuvarande situation och framtidsutsikter, is topresent the opinions of dairy farmers in Sweden, regarding the Swedish dairy industry and therelation to their own dairy production. A secondary purpose is to problematize how theconsequences of pastures and cultural landscapes influences human society as dairy farms andgrazing animals are becoming fewer.
Hållbarhetslivscykelanalys på kakel och klinker : Analys av vägen från vagga till grav ur ett hållbarhetsperspektiv
In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.
Importance of epigenetics in animal breeding : genomic imprinting
ABSTRACTThe aim of this study was to give an overview of the evidence for genomic imprinting in livestock and other mammals as well as outline the potential use of gene imprinting in livestock breeding. Epigenetics is the mitotical and meiotical partial hereditary variation in genomic activity without any alterations of the DNA sequence. An example of epigenetic regulation is genomic imprinting where one allele?s expression differs depending on which parent it was inherited from. These parent-of-Origin effects are currently overlooked in livestock production.
Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet
The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the Origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods.
In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.
Påsköns stenstatyer, moai : Vilket genus representerar de?
Abstract.The question in this analysis is which gender moai, the big statues on Rapa Nui, represent. My hypothesis is that they have developed from visual symbols to metaphores in mythologies from an polynesian context. That these statues were symbols for human Origin and creation of ancestors ideological power, and gods in consideration male gender. In the long isolation, in both time and space, the mytologies in Rapa Nui was changed, and the pictures got a new meaning. These changes depended on clearing of wood and big trees and the following difficult situation in farming.
Fortplantning och fortplantningsproblem hos tikar av svensk och finsk lapphund : en jämförande studie
The Swedish Lapphund is one of our eleven Swedish domestic breeds of dogs and one of Sweden?s oldest dogbreeds. The Finnish Lapphund?s Origin and physical conformation is similar to that of the Swedish Lapphund.
One aim of this study was to examine whether the average litter size differs between these two closely related breeds, and if so, try to find causes for this.

Made in Sweden : En flerfallstudie om ursprunget som mervärdeskapare
Vi har i uppsatsen valt att studera hur svenska design och hantverksföretag ser på möjligheterna vad gäller ursprungslandet som källa för mervärdeskapande. Detta i syfte att skapa en ökad förståelse för ursprungslandets betydelse för ett företags produkterbjudanden på den internationella arenan. För att uppfylla studiens syfte har vi utformat en huvudfråga enligt följande: Hur arbetar svenska design- och hantverks företag när de använder sig av ursprungslandet i sin internationella marknadsföring? För att besvara forskningens huvudfråga har vi arbetat utifrån en kvalitativ forskningsansats samt tillämpat en flerfallstudie inbegripande fyra svenska hantverksföretag. Uppsatsens teoretiska referensram innefattar en beskrivning av det resursbaserade perspektivet samt omskrivna varumärkesstrategier, vidare behandlar kapitlet teorier rörande ?country-of-Origin?. Ovanstående teoretiska block är av stor relevans för forskningens ämne och huvudproblem.
Problematiken vid samägd jord- och skogsbruksfastighet : De rättsliga förhållanden
The purpose of this thesis is to investigate and analyze existing law concerning joint owner-ship in agriculture and forestry businesses. Joint ownership often arises through a succes-sion of ownership, therefore we will go through the most useful methods.Even if the owners of agriculture and forestry businesses are getting older, the numbers of succession of ownerships are still low. A succession of ownership is important to plan and its time is demanding. Often it takes three to five years for the completion of a succession of ownership. Therefore, owners must start their planning in time and think about what is to come of their business.
Klimatanpassning av det svenska vägtransportsystemet : En diskussion om vilka åtgärder som kan vara samhällsekonomiskt lönsamma för att förhindra naturolyckor och deras konsekvenser
In light of the European Union`s 2012 theme year: Active aging and solidarity between generations I wished to gain an understanding of weather elderly immigrant are provided with equal possibilities and access to local community information as the majority population and their participation in activities arranged for senior citizens in the municipality where they live. I have done this by meeting with those who work in this capacity. I also chose to meet with representatives for immigrant organizations in the local community to enquire of their work with senior citizens within their own ethnic group. This is a qualitative study on a phenomenological ground based on nine interviews and four observations. I have had two theories to help me analyze my empirical material.

Visstidsdirektivets implementering i svensk rätt : Har korrekt implementering skett?
The essays main intent is to examine whether there has been a proper implementation of the Council?s directive 1999/70/EG into Swedish law regarding the requirement for measures to prevent the abuse of successive fixed-term employment contracts. To achieve this purpose there is a need for an examination of current law. The essay also has some secondary purposes. One of these secondary purposes is the question of whether the implementation of the Council?s directive 1999/70/EG has lead to a reduction of the workers employment protection, which is closely connected to my main question and the violation case.
