Vattenavvisning och smutsavvisning är två egenskaper hos textila produkter som idag eftertraktas av konsumenter. En ämnesgrupp som är direkt relaterad till ovan nämnda egenskaper är fluorkarboner. Ibland förs fluorkarboner på en redan färdigtillverkad textilvara genom impregnering, laminering eller beläggning. Polymeren PTFE, polytetrafluoreten, används inom textil beläggning och som huvudkomponent i membran för att skydda textiler från vatten och smuts. Syftet med detta arbete var att undersöka om någon effekt av vatten- och smutsavvisning kan uppvisas vid integration av PTFE-fiber i polyester- eller viskosgarn.

När tekniken ?cloud computing? eller datormoln först upptäcktes var det en teknik som krävde att en användare införskaffade hårdvara och kunskap för att skapa denna miljö. Denna teknik kunde inte uppfylla sin potential pågrund av en otillräcklig internetanslutning. I dagens moderna samhälle är tillgång till fiberanslutning stor och kostnaden låg vilket har lett till att antal hushåll med fiber fortsätter öka. Detta har medfört att datormoln i nutid kan vara av intresse för en hemanvändare, detta i form av molnlagring.Det här examensarbetet undersöker prestanda, säkerhet, integritet, replikering och skalbarhet hos två olika molntjänster.

Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.

Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.

The purpose of this report was to obtain an overview of rabbit meat production in the world, in terms of breeding and feeding. It examines how different feed components contribute to the health of the rabbit as well as the quality of the carcass, and the breeding strategies that are most common in the major producing countries. The production of rabbit meat in Sweden is at present not very large, but it is gaining ground, and that is why this paper mainly deals with the rabbit production abroad. This report also examines the disease Rabbit Viral Haermorrhagic Disease (RVHD) in Sweden, where this disease can cause big problems. The rabbit (Oryctolagus cuniculus) is very special, both in its reproduction and digestion. There is no specific mating season and the digestive tract is designed to digest forage efficiently.

Våmacidos är ett sjukdomstillstånd som uppstår då våmmens pH sjunker under det normala. Sjukdomen kan delas in i akut- respektive subakut våmacidos, beroende på grad av pH sänkning. Våmmens mikroorganismer bildar flyktiga fettsyror (VFA) från kolhydrater. Vid våmacidos bildas mer VFA än normalt på grund av för hög konsumtion av lättsmälta kolhydrater (stärkelse), framförallt kraftfoder. Detta resulterar i att våmmens pH sjunker för mycket.

The purpose of this thesis has been to gather knowledge about the complaints of tying-up in horses and to show that the importance of feeding. The thesis includes a literature review of tying-up how preventative measures by feeding can be made. In the equine sport, crosscountry, horses occasionally suffers from tying-up, a muscle disease. An increased knowledge about the disease is demanded by riders and trainers as the disease disrupts training and competition of suffered horses. A cross-country horse works very hard in training and during competitions but the work bouts are long enough for the muscle cells to use aerobic pathways in the metabolism.

This report describes the results of the project "Concept development of jet engine inspection plugs" carried out in the spring of 2008. The work was done at the department of product definition at the company Volvo Aero in Trollhättan. The objective of the work was to develop concepts for a "Volvo-unique" inspection plug. The work is part of Volvo Aero's focus on proprietary (self-developed) technologies. Inspection plugs can be found on virtually all aircraft engines and gas turbines.

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

BillerudKorsnäs is a leading global provider of primary fiber-based packaging materials and on Gruvöns Bruk in Grums, they have chosen to invest millions in the boiler at the facility to increase the total capacity of the factory. This results in the Pulp Flash Dryer at Gruvön being burden more, which makes it important that it is of great reliability and can be run with a high capacity. The reliability of the Pulp Flash Dryer at Gruvön is not as good as one could hope, which leads to reduced availability and production, as well as to increased maintenance costs. There are a number of different reasons for this, but all the casual links are not known.The purpose of this project was to perform a system analysis of the Pulp Flash Dryer to identify bottlenecks and the most critical parts from a capacity- and availability perspective. Appropriate methodology for the system analysis was used and would be used in a structured way to perform the analysis with data from the process and the maintenance system.
