Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the Relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..
The welfare of the laboratory mouse : comparison in development of mouse pups in three different individual ventilated cage (IVC) systems
Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and Relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.
Produktion av Pyrolysolja från kvistrejekt
Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting. Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.
Hur ser barns yttranden ut? : Yttrandetyper, bisatser och yttrandelängd hos svenska 3- och 4-åringar
Children?s utterances have been studied in different languages; however, only a few studies refer to Swedish. The aim of the present study is to describe utterance types, subordinate clauses and utterance length for a group of three and four year old Swedish children without known functional impairments.The study included 29 children, 17 girls and 12 boys, in a larger city in the south-east of Sweden. The children, all native Swedish speakers, were aged 3;0 to 4;11. Sound recordings were made during a playing session with one of the authors in the children?s day care centers.The utterances were divided into the categories elliptical responses, incomplete and partly unintelligible utterances, imitative utterances and independent utterances.
Preferensaktier och obligationer som fastighetsfinansiering
The recent turbulence in the financial markets has contributed to the banks becoming more restrictive to lend to real estate financing. Deleveraging in Europe's banking sector has also contributed to banks reducing their leverage and increasing capital adequacy to meet the new requirements. Loan-to-value ratios in real estate loans have fallen while banks' interest margins have increased, which has made property investors to look for alternative sources of funding in the capital markets. The two most interesting forms of financing for real estate right now is bonds and preferred shares as they fit property companies that generate stable and predictable cash flows. A bond is an interest-bearing debenture certifying that the purchaser has lent money to the company that issued the bond.
Relativvärdebaserad investeringsstrategi i industriföretag : Fungerar det och varför kan det fungera?
Flera tidigare studier har visat att det går att generera överavkastning genom att investera i aktier baserat på olika nyckeltal. Genom relativvärdering ställs företag i relation mot varandra för hitta indikationer på under- eller övervärdering. För att bidra ytterligare till den redan existerande forskningen fokuserar författarna till studien på en specifik bransch, industribranschen. Genom en branschindelning bör jämförbarheten öka mellan nyckeltal.Syftet med studien är att undersöka huruvida det är möjligt att generera överavkastning genom att investera i undervärderade aktier i industribranschen enligt nyckeltalen P/E, DY och P/BV. Resultatet kommer att härledas till och diskuteras utifrån teorier inom Behavioral Finance, för att förstå och förklara resultatet.Undersökningen baseras på en kvantitativ metod där tre nyckeltal har undersökts.
Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Effektiv lagerstyrning genom tillförlitlig prognostisering : Effective inventory control through reliable forecasting
This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

Norge - finansieringen av den åldrande befolkningen
As most developed countries Norway has an ageing population meaning that the number of pensioners is predicted to grow rapidly over the coming years. As a consequence the Norwegian pension system will not be able to provide for these future pensioners. Meanwhile, a rising number of early retirees and disability pension claimants is diminishing the real retirement age. Also the individual pension amount is growing while the pension system itself reaches maturity. In short, major reforms are needed in the Norwegian pension system.
RTLS - real time location systems : an inventory study for agriculture applications and requirements
The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture.
In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the Relative or absolute position. Empirical data can be received in real time from the nodes.
Att ha möjlighet till att leva in i döden på vård- och omsorgsboende : en litteraturstudie
Bakgrund: Den äldre populationen ökar och många av de äldre lider av flera olika sjukdomar. Därmed ökar behovet av professionell och god omvårdnad. Den äldre människan som ofta lider av flera sjukdomar bor vanligtvis sista tiden av sitt liv på vård- och omsorgsboende. Äldre människor vårdas inte utifrån ett palliativt perspektiv trots att behov föreligger. Palliativ vård kopplas ofta ihop med människor som är under 65 år och har en obotlig sjukdom exempelvis cancer.Syfte: Att belysa hur den äldre människan vårdas i livets slut på vård- och omsorgsboende, ur de äldres, de närståendes och vårdpersonalens perspektiv.Metod: En litteraturstudie inspirerad av Friberg (2006).
"What is it like to be one of these people?" : Narrativa strategier för att skapa inlevelse i reportage
The eyewitnessed reportage has a pronounced character of narrating. The imaginative power of the text helps the reader to empathise with the characters. That makes constructing empathy a necessary skill of reporters. But how can this be done?Despite a tradition of story telling among reporters, narratologists virtually have neglected the reportage genre.

Investeringsstrategier : En studie om relativvärdering som investeringsstrategi
Bakgrund: Något som många privatpersoner upplever svårt, är att välja aktier att investera i bland de tusentals som finns noterade på aktiemarknader runt om i världen. Enbart på Stockholmsbörsen i Sverige finns det enligt Nasdaq OMX (2010) 288 stycken noterade aktier att välja mellan på huvudlistorna. En investerare har idag även tillgång till mycket information om företagen vilket bidrar till att det blir svårt att sortera bort vad som är oviktigt. Då målet för många investerare är att slå index är det intressant att titta på investeringsstrategier som kan tänkas slå index på längre sikt.Syfte: Syftet med studien är att undersöka investeringsstrategier på Stockholmsbörsen baserade på nyckeltalen P/E-talet, P/S-talet, P/BV-talet och direktavkastning. Detta för att komma fram till om det är det möjligt att generera överavkastning genom att följa någon eller några av dessa och om det visar sig stämma, komma fram till vilket eller vilka nyckeltal som är att föredra.Metod: Studien bygger på en kvantitativ metod där fyra nyckeltal har undersökts.Resultat: Studiens resultat visar på att det är möjligt att generera överavkastning gentemot index genom att följa en investeringsstrategi baserad på de studerade nyckeltalen.
