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..

Bacteria are exposed to evolutionary pressure to an extent unlike other organisms. This leads to a high degree of adaptation to its surrounding. This thesis investigates the degree of adaptation towards higher accuracy in the transcription of DNA to RNA in coding sequences in the DNA of the E. coli bacteria. Two coding sequences with different nucleotide contents were investigated.

This paper tests the information signalling hypothesis on a sample of firms making open market stock repurchases. Using an earnings-based valuation model, we find that a majority of repurchasing firms are undervalued relative to their economic value. This result is consistent with previous academic studies, which claim that undervaluation is the prevalent factor explaining the observed abnormal return following the announcement of a repurchase program. We do not, however, find any evidence that the repurchase is consciously made by management to provide the market with new information. .

Clinical signs of hypocalcaemia in dairy cows are easily recognized, and a rapid response to treatment generally confirms the diagnosis in the field. However, clinical signs of other disorders in cows, such as toxemia, calving paralysis, or muscoskeletal injury, may mimic those associated with hypocalcaemia. Therefore, making a diagnosis of hypocalcaemia on the basis of clinical signs alone may be difficult. In ambulatory veterinary practices, cow-side tests are useful to make the diagnosis and prognosis easier. Kruuse?s Kalcium Test is a cow-side test based on the principle that calcium ions are necessary for coagulation of blood, and that chelation with EDTA prevent coagulation.

This study aims to evaluate the value relevance of Piotroski?s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used.

The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..

Syfte: Syftet med studien var att utröna huruvida produktionsmetoden påverkar passformen för singelkronor i kobolt-krom (Co-Cr) och samtidigt undersöka vilken produktionsmetod som ger det minsta utrymmet för cement. De produktionsmetoder som undersöktes var fräsning-gjutning (FG, motsvarande engelska term: milled wax ? lost wax), fräsning (F) samt lasersintring (LS). Metod: Undersökningen utfördes med replikametoden. Metoden som sådan är allmänt vedertagen och uppvisar tillförlitlighet vad avser att skapa en avbildning av cementfilmens tjocklek. Silikonavgjutningarna, tio stycken för varje produktionsmetod, snittades och undersöktes under ett ljusmikroskop vid 31 gångers förstoring.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.

The purpose of this study was to gain insight into refuges experience of traumatic events such as torture, political persecution, war, natural disasters and other trauma. For the study used theories which, inter alia, deals with many of the refugees coming to Sweden is influenced by various psychological trauma and may be accompanied by torture, political persecution, war, natural disasters and other trauma. To this study, a survey with 40 participants, 17 women and 23 men. There was also an interview on the Internet with a refugees consultant within the Red Cross. The men had higher average than women in all the perceived problems.

Aim: To describe perceptions about written and verbal information regarding diet and physical activity in women with breast cancer and to study possible differences between ages and perception. Method: A cross-sectional study was conducted and consisted of 57 women with breast cancer stages I-III who started adjuvant chemotherapy within a year (2007-2008). A questionnaire, regarding their perceptions about the written and verbal information they had received about diet and physical activity, was responded to three months following treatment completion. Between 67-93 % of the participants responded to the questions. The answers was analyzed with descriptive statistics and Mann Whitney U-test.

Det positiva sambandet mellan stress och idrottsskador är väl dokumenterat i litteraturen. Ett ökat antal psykologiska skadeförebyggande interventioner visar att det är möjligt att förebygga idrottsskador genom kognitiv beteendeträning. Användandet av biofeedback tillsammans med kognitiv beteendeträning i skadeförebyggande syfte är dock en relativt outforskad interventionsstrategi (Johnson, 2007). Syftet med studien var att undersöka om det genom interventionsbaserad kognitiv beteendeträning i kombination med biofeedbackanvändning gick att minska antalet idrottsskador för fotbollsspelare. Deltagare ifrån fyra idrottsgymnasier (16-19 år) delades in i en experimentgrupp (n=13) och en kontrollgrupp (n=14).

ABSTRACT Epilepsy describes a neurologically caused condition which involves seizures. Epilepsy can be classified according to different types of causes and the nature of seizures can vary. Medication for epilepsy in dogs is limited in comparison with human medicine. Idiopathic epilepsy is the most common neurological disease and one of the most common genetic diseases in dogs. Because epilepsy has a higher prevalence in certain breeds, there is reason to suspect that it is a hereditary disease. The inheritance of idiopathic epilepsy is for most breeds not determined, except for a few variants of the disease.
