Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

Detta examensarbete visar att upplösande av samägande av fast egendom är viktigt då ägandet av fast egendom är kopplat till rättigheter såväl som skyldigheter. Det är av mycket stor vikt att ägande och brukande av skogsfastigheter fungerar och att det finns förutsättningar för att lyckas med det. Dock kan samägandet i vissa situationer hindra utvecklingen av fastigheten. Skogsbruket är en viktig inkomstkälla för den private skogsägaren såväl som för Sverige, skogsbruket i vårt land stod 2010 för 7 % av världens totala export. Även om Sverige är ett litet land i världen, är det inte obetydligt inom skogsbranschen.

In many industries today, there is a growing emphasis on calculations. They are used to manage and control the activities in today?s organizations, one of these industries is the process industry.

Syftet med denna undersökning är att ta reda på hur lärarens skriftliga respons uppfattas av elever och hur de arbetar med den samt hur lärare tänker kring skriftlig respons. För att finna svar har vi valt att använda en kombination av en kvalitativ och en kvantitativ ansats. Undersökningen har genomförts i form av två fallstudier i två olika utbildningsmiljöer. Undersökningen består av sammanlagt sex elevintervjuer, två lärarintervjuer och 41 deltagande elever i en enkätundersökning.Båda uppsatsförfattarna gör var sin fallstudie som innebär att intervjua en lärare och tre elever vardera samt genomföra en enkätundersökning. Undersökningen visar att eleverna i respektive fallstudie uppfattar den skriftliga lärarresponsen som positiv.

New Zealand is currently the third largest global producer of kiwifruit and thus plays an important role in the international market. Exports of kiwifruit are also of significant horticultural value for New Zealand and in 2007 the kiwifruit industry accounted for export values of NZ$790 million. The global kiwifruit market has experienced substantial changes in recent years and is likely to change significantly in the near future due to developments in production sources, adjustments to trade policy settings and shifts in consumer preferences. The New Zealand kiwifruit industry needs to consider what the impacts of these changes might be so that future strategies can be constructed effectively. Little quantitative modelling has been done in New Zealand to consider the impacts of changes to the global kiwifruit industry. The major contribution of this research was the development and calibration of a kiwifruit industry-specific partial equilibrium trade model. The model was then used to examine the impacts on New Zealand producers of these trade-related changes in the global kiwifruit market.

Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding.A case study has also been performed for the company Wenmec. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2.

Myanmar?s entry in Association of South Eastern Asian Nations (ASEAN) in 1997 brought about several economic and social changes. One important change is tariff reduction through the Common Effective Preferential Tariff (CEPT-scheme), which increased Myanmar?s export to countries outside the ASEAN. The increase in exports facilitated trade creation and investment creation for Myanmar.

Over the past two decades, trends of integration processes in terms of citizens of different ethnicities, different gender and different sexual belongings, etc. has grown thanks to debates and new legislations. A marginalized and discriminated group in society such as women, immigrants, homosexuals, transsexuals and people with disabilities during this time has gained momentum in the community. The curiosity over whether these developments have changed our attitudes and values to the world around us, and if so how, is the reason for this master's thesis in disability studies.The Swedish development forms the basis for my belief on a younger generation of people who would be more tolerant than previous generations, in terms of what is considered to belong to the norm in our society, or not. The purpose of this study is therefore to increase knowledge about what beliefs young people today have about people with disabilities.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

This essay examines whether, and if so to which extent, the project Export MatureDestination in the Biosphere Reserve Vänerskärgården with Kinnekulle can combine the goalof the tourism industry, i.e. to double tourism between 2010 and 2020, and the goals of theBiosphere reserve, i.e. sustainable societal development and a sustainable biosphere economy.The aim is to examine how key individuals in the project approach sustainable developmentand economic growth, representing the two main interests in the area. Examining the state ofthe two interests the following examples are used: the position of sustainable development inregard to economic growth, the opportunities and challenges in the area and unity concerningthe goals of the tourism development in the region. The study is conducted through qualitativeinterviews with key individuals and a descriptive document analysis of the most importantpolicy documents.

Since we all live in an increasingly globalized world where goods and money are transported more easily and with tougher competition, it is a natural step for Swedish companies to establish themselvs abroad in order to increase their gorwth rate and reach more customers. Today all of us belong to the same global network and the purpose of this thesis is to investigate which factors are important for companies when they choose to establish themselvs on a foreign market. The focus of the investigation has been the market of Germany and Spain, since both countries just like Sweden are members of the European Union, but still have quite different characteristics. We, the authors, have also been living in Spain and Germany during the time of investigation and writing. The companies we have chosen to look closer into are Abba Seafood, which now has merged with Procordia Food, and Oatly AB.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.
