We collected the data for decomposition of spruce litter to determine the limit values of mass loss and to find both chemical and climate factors that influence limit values. Our data contained 28 sequences of spruce which mainly in Sweden and a small part in other places. We choose mean annual temperature (MAT) and mean annual precipitation (MAP) as climate factors and water solubles, lignin, N, P, K, Ca, Mg and Mn as chemical factors. Then we got the estimated limit values by performing a nonlinear model with mass loss and time spots, and found out the influential factors by using another linear mixed model. At the end we knew that linear mixed model is a proper and efficient approach for determining the factors, P and MAP are the significant factors and Species is a good random effect to explain the variance within groups.

Background/Problematization: The statutory audit was abolished for small limited companies in Sweden, in 2010, with the intention of easing the burden on enterprises with high audit expenses and enhancing Sweden's competitiveness. After the abolishment, the debate about statutory audit has rekindled once more, where various actors and scholars emphasize the meaningfulness of statutory audit for small firms in terms of fighting criminality and ensuring financial information quality for stakeholders, while others argue that the benefits of the audit do not justify the expenditures incurred. Purpose: The purpose of this thesis is to map the debate about the statutory audit for small companies in Sweden since the abolishment in 2010 by exploring the main stakeholders, their differences in power as well as the arguments provided by the debaters. Methodology: This thesis adopts a critical discourse analysis method with an abductive research approach, where predetermined codes were developed in a scheme in order to collect the empirical data. The study includes 90 articles that were collected and used from 8 newspapers, magazines, or websites. Findings: The findings suggest that auditing- and accounting organizations, legislators, authorities, audit firms, clients, creditors and business associations are the main stakeholders of the debate. Further, the prominent arguments for a reinstatement are the increased criminality and the decreasing financial quality in the absence of an auditor, while the arguments for raised limit values involve the lack of necessity of audit in small firms as well as the incurred cost and lack of competitiveness due to statutory audit. Our findings indicate that there exist differences in power in the debate, where some stakeholders are more prevalent in the debate and are seen to be more influential than others.

Syftet med arbetet var att samla in mätdata för att kontrollera luftkvalitén ombord på två svenska fartyg, för att sedan jämföra resultaten med Arbetsmiljöverkets hygieniska gränsvärden och den svenska normalbefolkningens exponering för olika ämnen. Resultatet från studien var också tänkt att vara till hjälp för att utforma nya råd och rekommendationer för att minimera exponeringen och även till att bidra med material för fler framtida studier. Under cirka en vecka ombord på fartygen samlades data in med hjälp av passiva provtagare för att registrera halter av bensen, kvävedioxid och polycykliska aromatiska kolväten. Resultaten visade att luftkvalitén ombord på de två fartygen generellt sett är god. Samtliga uppmätta halter låg långt under Arbetsmiljöverkets gränsvärden och det skiljde sig inte mycket varken mellan fartyg eller jämfört med den svenska normalbefolkningens exponering. Därför är inte svensk sjömän ombord på svenskflaggade fartyg i större fara för toxiska luftföroreningar ombord jämfört med när de är hemma. / The main purpose of this study was to measure and evaluate the air quality onboard two Swedish ships, and compare the results with the exposure limits laid out by the Swedish Work Environment Authority (Arbetsmiljöverket) and the Swedish population’s exposure to various substances. The results of this study were also meant to be helpful to form new advice and recommendations to minimize exposure and also to provide material for future studies. During approximately one week onboard the two ships data were collected using passive samplers to register levels of benzene, nitrogen dioxide and polycyclic aromatic hydrocarbons. The results indicated that the air quality onboard the two ships were generally good. All measured concentrations were well below safety applications and it did not differ very much neither between ships nor compared with the Swedish population’s exposure. In conclusion, Swedish sailors onboard Swedish ships are not in greater danger of toxic air pollutants onboard compared to when they are at home.

I samband med en ökad befolkningstillväxt och en ökad ekonomisk tillväxt påverkas konsumtionen och produktionen av olika varor, vilket leder till ökad efterfrågan på råvaror. En del av efterfrågan kan mötas genom återvinning, men problemet är att avfallsströmmar ofta innehåller en blandning av ämnen. Detta leder till en spridning av farliga ämnen, där mängden farliga ämnen måste minska i strävandet mot en cirkulär ekonomi. Vid konstruktionen av olika anläggningsprojekt finns det möjligheter att förbättra hushållningen av resurser genom att återanvända avfall. Avfallet avser restprodukter, jord och sorterad bygg- och konstruktionsavfall enligt Danmark, vilket skiljer sig från Sverige som avser avfall med främst geologiskt ursprung. Syftet med denna rapport var att identifiera utgångspunkter för att reglera farliga ämnen, samt att förstå vilka prioriteringar som har gjorts och vilka konsekvenser det får på gränsvärdena. Detta genomfördes genom att jämföra Sverige och Danmark för att se hur utgångspunkterna kan hjälpa till att förstå likheter och skillnader. Resultatet baseras på en textanalys av ett fåtal myndighetsrapporter som var till underlag för gränsvärdena, där intervjuer med relevanta aktörer har genomförts i ett tidigt skede för att förtydliga innehållet i rapporterna.  Resultatet visar att Sverige anser att både skydd av hälsa och miljö är viktiga utgångspunkter vid framtagandet av olika gränsvärden. Danmark prioriterar främst skydd av hälsa, där olika modeller och antaganden lett till att gränsvärdena skiljer sig mellan länderna. Resultatets jämförande del visar att länderna använder olika metoder och antaganden när de ta fram gränsvärden för totalhalt och utlakning. Detta är en av anledningarna till att gränsvärdena skiljer sig. / Population and economic growth have affected the increase of consumption and production of goods, and with that the demand for raw materials. A part of the demand can be met through recycling, the only issue is that the waste streams are not in the form of pure materials. Often, they contain a mixture of substances, which affects the dispersion of hazardous substances. Therefore, the reduction of these substances is necessary in a circular economy. Reuse of waste- based aggregates is possible for construction facilities and is a way to improve resource management. In the case of Denmark, the referred waste consists of residual products, soil, and sorted building and construction materials, which differs from Sweden. Instead, Sweden refers to waste of mainly geological origin. The purpose of this study was to identify different approaches and starting points to regulate hazardous substances and to understand how various priorities affected the limit values. A comparison between Sweden and Denmark was done for a better understanding of the differences and similarities. A qualitative method was used based on interviews with relevant actors in addition to a text analysis of government background reports. The interviews helped to understand and clarify the information in the reports at an early stage.  The results show that Sweden prioritizes the protection of health and the environment, which are their main starting points when producing the limit values. Denmark also prioritizes health, where they use other models and values when producing the limit values. The comparison shows that the countries use different methods and assumptions when calculating the limit values for total content and leaching. This is a part of the explanation to why there is a difference in their legislation.

The construction industry is one of Sweden's largest industry emitters, an industry operating in the centre of cities worldwide, day and night. In order to achieve a more sustainable future and reduce greenhouse gas emissions, the construction industry must be less pollutive. On 1 of January 2022, the Swedish government implemented new regulation, The Act of Climate Declarations, within the construction industry, to enhance the knowledge of the climate impact of new buildings. The purpose of this study is to examine the implementation process of said regulation, its implications on concerned industry actors, and to investigate whether current restrictions would benefit from more strict policies or not. In this study, Institutional theory has been applied to analyse conducted empirical data to examine how the regulation has influenced different actors behaviours and practises. The result shows that the regulation has been widely accepted within the industry. Furthermore, this study shows that barriers are mainly found regarding the narrow scope the regulations require. Opportunities in regards are that actors are hopeful that the regulations could be a first step toward a more sustainable industry at large. These findings have added evidence that adds to current literature on future sustainability investments, such as limit-values and new proposals communicated by the Swedish Government while this thesis was written.

Aim of the proper track design is build track, which enable smooth run of the vehicle as much as is possible complying with the safety rules and reasonable level of comfort for passengers. However, this track has to be maintainable and the vehicle shouldn’t face unacceptable amount of wear. On the other hand it is clear that it is impossible to build ideal (straight) track because of many environmental and morphological conditions. So the rules for track designing have to be set carefully in order to produce a good track design which meets the conditions mentioned above. The principles for track designing are evaluated with using the results of track test running dynamic behavior of the vehicles in this study. These tests were made for couple vehicles on several track sections. The influence of design parameters on the dynamic behavior are evaluated based on these results. That’s defining one of the basic part interactions between vehicle and track. Evaluation of the quality of track geometry in service has the same or may be higher importance. Limit values as defined in standard ČSN 73 6360-2 was set partially in consideration results of scientific studies, but partially in consideration of as common practice. So that part of this work is verification of the influence of tolerance in each parameter and their combinations in order to allow reasonable establishment of their limit values for track maintenance and for preventing of train derailment.
