A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A Comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

The use of earth bricks in Scanian building traditionThe present work is concerned with the manufacturing and use of earth bricks inbuilt heritage in the south Swedish province of Scania. The first part of the studyprovides a thorough description of the traditional use and manufacturing of earthbricks based on relevant literature, archive material as well as interviews withinformants. This forms a basis for the second part of the study in which practicalexperiments on and tests with earth bricks where carried out. This involved themaking of traditional earth bricks of different composition. The new handmadebricks were compared with industrially produced bricks (extrusion bricks) and oldhandmade bricks.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the Comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the Comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

This paper deals with institutional and structural factors' influence on democratic transition in limited multiparty regimes in Sub-Saharan Africa. Comparing the cases Kenya and Tanzania, of which the former has made a transition to democracy and the latter has not, this paper reaches the conclusion that political traditions, the coalescing of the opposition, and the elites ability to learn from the electoral process is essential for a transition to democracy. In the specific cases, the harshness of the Moi regime and the Tanzanian vision of national unity may possibly carry some explanatory power, alongside the pressure from international actors.These results have been reached through the application of a comparative case study, where democratic transition constitutes the dependent variable. It should be noted that a harsh definition of the term transition has been applied, according to which the incumbents actual loss of an election is a necessary indicator for transition. However, the Freedom House and Polity scores have been brought up as complement of this definition.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for Comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

The purpose of this essay was to examine and shed light on bullying as a groupprocess, a social phenomenon taking place in a school setting, to increase the understanding of the phenomenon. A theoretical overview of the litterature on bullying was made to investigate bullying and to give the reader a view of the researchfield. A total of 77 articles was studied. With the intention of studying bullying from a groupsychology perspective a metaanalysis was performed discussing groupphenomenon such as rolebehavior, responsibility, cohesiveness and norms in Comparison to bullying episodes.Stemming from this analysis the question whether bullying can be view as a response to groupthink emerged. This question also constituted the secondary aim of this thesis.

This thesis presents the question of a possible breakthrough for mobile payment solutions in Sweden. The way payments are made and the way cash is being used in the society is changing. To be accepted as an alternative method, if cash isn't king anymore, the new technology will have to acquire user acceptance. In this thesis a case study of Swish, a mobile payment solution for P2P-payments, is presented. The focus of the study is customer value and technology acceptance of the service.

This study explores whether environmental, social and governance (ESG) issues affect the monetary value of a company.The samples used in this study have been taken from the Johannesburg Stock Exchange (JSE) in South Africa. Since 2010, JSE have been categorizing companies using the King Code III criteria to establish a Socially Responsible Investment index (SRI index). Companies that fulfill the required number of criteria are classified as 'best performers' using the SRI index.  In this study the monetary value of a random sample of 'best performers' has been compared to the monetary value of a random sample of companies without an SRI index evaluation.This study found that companies without a SRI index have a higher unique risk, which means a lower stock price with a higher dividend yield. Companies with an SRI index evaluation have a lower unique risk, which means a higher stock price and lower dividend yield. In conclusion, this study shows that SRI adjusted companies have an enhanced monetary value in Comparison to non- SRI adjusted companies..

The blog has become a widely discussed subject, but while marketers do invest in blogs, there is little evidence on the how the blog works as a marketing tool. Therefore, we thought it would be interesting to create a greater understanding of the blog's potential communication effects. To demonstrate the potential of the blog in Comparison with more traditional media, we decided to compare the communication effects achieved by a blog with those achieved by an online magazine. We pursued an experiment where we exposed an identical text about a brand to respondents in seven blogs and in seven online papers and measured the resulting communication effects in terms of attitudes and intentions towards the exposed brand. The quantitative study showed that the blog in some basic aspects works as a more traditional media; when the consumer forms positive attitudes toward a text in a blog, the attitude spills over to the attitude toward the brand, with higher buying and w-o-m intentions as a consequence.

In many of the world's countries, there is a national organization responsible for marketingthat country as a tourist destination. Through their offices, these organizations work towardsthe creation of effective strategies and a deeper understanding of local markets. Usingqualitative methods such as interviews, observations, and thematic analysis, we managed toinvestigate how the Czech and the German national tourist offices operate, and whatstrategies they are implementing to increase the volume of tourism. The study focused on theanalysis and Comparison of the organizations' goals and communication channels.The results show that the investigated tourist boards operate in a similar manner with smalldifferences concerning choice of strategies and communication channels. These discrepanciescan be partly explained by differences in the organization's ownership forms and theconsequences that follow that fact.
