AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.

Sweden has for years been struggling with high youth unemployment. The problem is also a hot topic of discussion among experts and politicians, often leading to different proposals to solve the problem. The government chose in 2006 to do something about youth unemployment by lowering payroll taxes for employees up to 25 years. But many experts and studies show that the effects failed to materialize.This study will try to find out if the government subsidies have given any effect on the youth unenployment either by new jobs created or by movement in the labor force. I will use a regression model with an dependent, "difference in difference" variable where the change in the number of employed young people are compared to the change in the number of employed in the subsequent age group.The results show that subsidies are not given any positive effect on the youth employment rate in relation to the subsequent age group..

Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).

The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.

Why has some cyber-attacks been more successful than others? There has been in the near past examples of cyber-attacks used with different purposes. How do we understand these chosen targets and what result the attack accomplished?Research has discussed similarities between aviation warfare and cyber warfare, and how the first could explain what is happening in cyber warfare now. There is also opposing opinions whether cyber warfare should be seen as a method to alone force a will on your opponent or if cyber warfare should mere be supporting other military means.

The aim of this qualitative study was to investigate the participants experiences of a parent support group and the effect of their participation on their parental role from a learning perspective. As the parent support group takes place as a group activity, the focus was on the individual learning processes which, in turn, are influenced by both the group itself as well as the leaders of the group. The empirical data was collected from a focus group interview with four mothers, and analyzed using empowerment and coping theories. Based on the participants´ narratives, the result showed that the parent support group had a great social and pedagogic effect on the participants. As a result of the received knowledge in the group from both leaders as well as from other participants, they felt less stressed and more confident in their parental role.

We have examined how the dependence, identity and social bonds affect customer loyalty and attachment to a training centre. The method used is a survey on SATS Karlstad city where 128 respondents were asked, out of which 118 surveys were used in the final analysis. The data was analyzed using ANCOVA and multiple regressions.The result showed significant relationships on attachment between identity and dependence. Social bonds had no significant effect on the attachment a member have towards training centre. Customer loyalty was measured by how long the individual has been a member and his or her training frequency.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

AstraZeneca in Mölndal (AZRDM) uses beagles bred at Rååhöjdens kennel in Örkelljunga for their research purposes. The staff wishes to have mentally stable dogs to work with, sine stress can effect the research results. The purpose of this study was to put together the testresults from dogs delivered 2003 and 2004, to see if there is a connection between delivery age and testresult. We have also worked out a method to test if early planned handling of the dogs makes a difference on how the dogs later respond in a testsituation, and tried this method in a pilotstudy. The data that we have based our calculations on is 172 dogs, divided into 108 males and 64 females. We found a significant connection between the age at delivery and the testresult in contactability for female dogs delivered in 2003, where increasing age led to decreasing grades in the test at AZRDM. When looking at the difference in testresults between test number two at the kennel and the test at AZRDM we found a significant connection for female dogs delivered during 2003, ie the difference takes on a more negative value with increasing age at delivery. We found a difference between the two sexes in our calculations.
