This report is the written result of a Master Thesis conducted at the Division of Machine Design at the Faculty of Engineering at Lund University. The project has been carried out in collaboration with BorgWarner TorqTransfer Systems (TTS) AB in Landskrona. The car industry is growing vastly and thereby the associated levels of CO2 emissions. Extensive and sharpened regulations are continuously b
A new oxygen barrier film that is made of arabinoxylan has been developed by the company Xylophane. Arabinoxylan is available among other things in wheat bran. But a problem with the method of extracting the arabinoxylan is that after an alkali extraction is ultrafiltration used to remove impurities and the flux during this is quite low. In this project is it investigated if gas sparging with air
The purpose of this thesis is to compare best-selling business literature in China and the US. Snapshots of Amazon.com and Amazon.cn bestseller lists were captured in early 2014, and the 25 highest ranked titles in the designated “business” category on each website form the foundation for comparison. The books mainly touch on Economics & Politics, Management Studies, Productivity & Life Ma
Renewable energy is gaining increasing importance in the generation of power due to the finite existence of fossil fuels and concerns about climate change. As its demand grows financial interest from investors’ increases, thus it is important to find the most effective way of quantifying the risk of the renewable energy market. Furthermore as renewable energy can be viewed as an economic substitut
The complement system can be activated by three different pathways in the body. It is wanted to be able to detect deficiencies of these activation pathways and Bioporto A/S has acquired the commercial rights to a set of ELISA based assays. There is a need in these commercial assays for optimisation of dilution and wash buffers since the idea with the ELISA kit is to sell it as a “ready-to-use kit”
The purpose of this report is to evaluate a direct driven permanent magnet motor in high accuracy position and low speed operation. Actuation in this case is usually accomplished by stepping motors combined with belts and pulleys. High accuracy positioning is considered to be within 0.1 degrees and low speed 0.05 degrees per second, while at the same time have a 180 degree step response within 0.5
Both e-commerce and m-commerce has had and have a big impact on how business today is operated. Furthermore, e-commerce is responsible for creation of many new jobs and its role to the overall economy in Europe is becoming increasingly important. E-commerce is a big part of retail and commerce and is constantly growing. However it is maybe not equally well known that the latest year mobile commerc
This study investigates how lead content and bioavailability in soil affects growth and root/shoot ratio in three commonly cultivated species: wheat (Triticum turgidum), clover (Trifolium) and radish (Raphanus sativus). The study investigates the levels at which soil lead content contribute to toxic effects in plants, and when it may pose a risk to consumers. In addition, lead accumulation and the
Mot bakgrund av rådande kunskapsparadigm inom barnpsykiatrin samt förändringar i samhällets syn på barns psykiska hälsa avsåg studien att undersöka föräldrars syn på orsaker till ADHD och om denna kunde kopplas till behandlingsönskemål. Avsikten var att utröna om det fanns ett behov av behandlingsinsatser som adresserade mer än barnets ADHD-problematik. Studien genomfördes som en enkätstudie (N = Given the paradigms which are currently predominant in child and adolescent psychiatry and the changes in the societal view of children’s psychological health, this study examined parental attitudes towards the causes of ADHD and if these were related to choices of treatment. The aim of the study was to determine whether there was a need for treatment which addressed more than just the ADHD sympto
This master thesis was partly performed as a field study in Gaborone, the capital city of Botswana, located in southern Africa. The semi-arid climate in Botswana together with a rapid financial development in the country during the last decades has increased the need for water. The last years the water situation has been strained in Gaborone, and Gaborone dam which used to be one of the city’s dri
Diabetes Mellitus is a generic term for metabolic diseases were insulin levels are insufficient and in type 2 Diabetes Mellitus insulin also fails to stimulate glucose uptake. Recent findings indicate that cells from the innate immune system could be involved in development of both type 1 and type 2 Diabetes Mellitus. Basophilic granulocytes are part of the innate immune system and contribute to h
Området för hemlig avlyssning av elektronisk kommunikation (hemlig teleavlyssning) och hemlig övervakning av elektronisk kommunikation (hemlig teleövervakning) är ett område som tidvis vållar stor debatt bland jurister och även bland allmänheten. få EU-rättsliga akter har nog varit så medialt uppmärksammade som datalagringsdirektivet som nyligen ogiltigförklarades av Europeiska unionens domstol. DThe area of covert interception of electronic communication (telephone tapping) and covert surveillance of electronic communication (covert telephone surveillance or metering) is an area which at times causes much debate in the legal profession and among the general public as well. There are probably few legal acts of the European Union that have received as much attention in the media as the Data

An analysis of the two fuel companies' communication of responsibilities regarding climate and envi-ronmental issues. This master thesis examines how two fuel companies rhetorically communicates its view of responsibility for environmental and climate issues on their websites. In order to prov
Bakgrund: Den här studien undersöker elevers upplevelse av ljudmiljön i grundskolan. Forskning visar att dålig ljudmiljö försämrar bland annat taluppfattning och arbetsminne. Man har sett att barn påverkas i större utsträckning än vuxna men det finns få studier som undersöker hur de själva upplever ljudmiljön. En enkät utvecklades 2013 i England för att undersöka detta. Syftet med denna studie är
