Betydelsen av hästens hud och päls för reglering av kroppstemperatur i kyla ? vad händer vid klippning och täckning?
The horse is a homeothermic animal and to keep a constant body temperature in winter season is important. Acclimatisation is to provide means for a good thermal insulation consisting of skin, hair, and an outer air layer. The skin covers the horses body and it is composed of three main layers where the top layer of the epidermis consists of dead keratinized cells that are constantly being sheed. The dermis is composed of collagen connective tissue that give the skin its strength. The bottom layer with subcutaneous fat provides a thermal insulation and can be used as an energy reserve in cold weather.
EU:s påverkan på västra Balkan : Det regionala samarbetet Ett fall av europeisering?
The general aim of this paper is to describe how the European Union can affect and transfer their conditionality politics to the Western Balkan countries. A specific purpose of this study is to describe and explain what we in this paper consider to be a specific additional membership criterion, regional cooperation that has been especially designed for this region. The point of departure for this paper is Europeanization theory that will be used to study the European Union?s impact on non EU-members in Europe. The theoretical Europeanization mechanisms are taken from Heather Grabbes ?Europeanization model?.

Pelletskvalitet : Test av olika råvarumixer i pelletstillverkningen vid Rindi Västerdala AB:s bioenergikombinat i Vansbro
Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.
E-arkivering hos stadsarkiv : Mellanarkivslösning i sitt sammanhang
Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.
Solvärme med säsongslager i Lyckebo
The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.
Internprissättning inom processindustrin: en fallstudie av driftsorganisationen inom pappersindustrin
Sedan 1950-talet har trenden för företag gått mot mer decentraliserade organisationer för att klara den ökade konkurrensen på marknaden. Decentralisering av ansvar medför emellertid att informationsasymmetri uppstår och företagsledningen tappar således kontroll över ansvarsenheterna. För att säkerställa att de olika ansvarsenheterna skall handla i enlighet med företagsledningens intressen krävs ett väl utformat ekonomiskt styrsystem. Ett ekonomiskt styrsystem kan i princip utformas på många olika sätt, varav internprissättning är en metod för att lösa styrproblematiken. I teorin skapar internprissättning ett antal fördelar såsom styreffekter, motivation och bättre resultatbedömning.
Franchiseföretaget jobzone : En studie om utmaningar och problem kring överföring av affärskoncept och organisationskultur
ABSTRACTHelena Nowachek The purpose of the following study is to focus upon the possibilities and challenges associated with the transference of corporate culture from one organization to another. I have chosen to address this by looking at the franchise company Jobzone, which works specifically with recruitment and outsourcing. As a method I have interviewed three people in Jobzone: one person who is responsible for education, one franchising boss in Sweden and one franchisee. To delineate the concept of culture I apply both Schein?s model, in which he divides culture into the three levels of artifacts, values and basic assumptions, as well as a general theory of communication.
Energianvändning på Volvo Lastvagnar Tuve
Volvo Trucks is the second largest manufacturer of heavy trucks, with factories in several countries and with around 21 000 employees. At the plant in Tuve, trucks have been built since 1982 and the activity mainly consists of producing side members and to assemble and packing kits of trucks. In 2005, the factory in Tuve launched the ambition to be the first carbon dioxide neutral vehicle factory in the world. This will be implemented by streamlining and investing in renewable energy. The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit).
Implementering av Virtuellt Byggande i byggprocessen : Fallstudie av NCC Construction Sverige AB
Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.
Förbättrad Kravhantering med hjälp av Lösningsinriktad Pedagogik
Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements.
Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus
The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.
Solenergisystem i Hammarby Sjöstad
Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.
Svett och blod : modernitet, kroppskultur och ras i Gymniska Förbundets tidskrift Gymn, 1928-1932
This study aims to investigate and describe the direction of the ideological development of the Swedish gymnastics association Gymniska Förbundet. Between 1928 and 1932, this organization transformed from a purely gymnastic and cultural association into an influential platform for the production of Swedish nationalist ideology. Based on theories of National Socialism?s formation within modern society, the analysis focus on the conditions regulating Gymniska Förbundets relation to modernity. Thus the study examines the association?s ideas in relationship to the concept of modernity.
Introduktion för arbetsledarrollen
Syftet med detta examensarbete är att komma underfund med hur introduktionen kan förbättras för nyanställda arbetsledare utan tidigare erfarenheter från arbetsområdet. Examensarbetet är en respons på Peabs interna enkät som under ett antal år belyst hur medarbetarna bland annat ser på trivseln och arbetsmiljön på sin arbetsplats. Denna enkät är till för att finna förbättringsområden. Flera anger att de anser att introduktionen är otillräcklig och behöver förbättras.Denna rapport använder sig av en kvalitativ metod med intervjuer av tio personer med koppling till yrkesrollen arbetsledare samt ytterligare tio kompletterande intervjuer.De huvudsakliga slutsatser och förbättringsförslag som dragits från intervjuerna är att nyanställda arbetsledare ska få tillgång till bättre arbetsbeskrivningar om hur Peabs arbetsmetoder och vad dess kärnvärden är och dessutom få klart för sig vad företaget har för förväntningar på de nyanställda.Större delen av intervjupersonerna ansåg att någon form av strukturerad utvecklingsplan var att föredra. Under rapportskrivandet upprättades följaktligen en sådan, som anger vilka moment och fördjupande kurser som är lämpliga för en nyanställd arbetsledare.
