Amelogenin, a protein that takes part in enamel development, has some interesting physicochemical properties such as the formation of nanospherical aggregates. Furthermore, its derivatives have shown regenerative properties and have already been commercialized for that purpose. Therefore, it was of interest for this project to evaluate mammalian cell attachment and proliferation on engineered vari

In recent years, the field of mass spectrometry (MS) has grown significantly, allowing for shotgun proteomic experiments to be used increasingly in biomarker discovery experiments. However, using standard methods of MS not all peptides present in a sample may be identified. To combat this, a procedure termed alignment, or match-between-runs, is used to propagate identifications from one run to ano

Fram till idag har framförandet av ett motorfordon krävt en mänsklig och närvarande förare. Med en mänsklig förare följer en mänsklig faktor. Under de senare åren har fler automatiska funktioner implementerats i nya bilar och självkörande bilar på högre nivåer har börjat utvecklas. Denna utveckling påverkar mänskliga faktorns inverkan. Syftet med examensarbetet är att utreda vilken problematik ochUntil today, the performance of a motor vehicle has required the present of a human driver. With a human driver follow human factors. In recent years, more automatic functions have been implemented in new cars and self-driving cars at higher levels have begun to develop. This development limits the influence of the human factors. The purpose is with the thesis project, to investigate which problem

This analysis examines the correlation between the stringency of environmental policies and the economic output in terms of real GDP. The data is covering real GDP, the stringency of market based as well as non-market based environmental policies, interest rates, total factor productivity and human capital. 33 countries, among the OECD and the BRICS, are being analyzed in the regression model duri

This research is an attempt to critically examine the impact that China’s aid program has had upon IMF conditionality. By building upon the work of Diego Hernandez (2017) who found that with every 1% increase in Chinese aid, the World Bank typically lessens its conditions for market liberalisation and economic transparency by 15%, this paper looks at the background surrounding China’s rise to beco

The Light Dark Matter Experiment (LDMX) is a fixed target experiment that will search for dark matter, but is still in the development phase. An important aspect for the experiment is the discrimination of signal and background events. Here this signal and background discrimination is inspected using a machine learning technique called a Boosted Decision Tree (BDT). This is done using Monte Carlo

The kinetics of the catalytic conversion of ortho- to parahydrogen was studied for the two catalysts, IONEX® and OXISORB®. The study also involved the optimization of an experimental technique for the conversion of orthohydrogen in a static setup. The main focus of the optimization being directed towards the analytical setup, where the acquisition of information and interpretation of the data were

Ease of Doing Business Index is published every year by the World Bank, and is used to describe how simple it is to start-up and run a business in different parts of the world. The index is constructed by eleven indicators, which are based upon around forty underlying variables. This essay examines the correlation between the underlying variables for the indicators Starting a business and Paying

This Master Thesis describes the product development of a medical laboratory machine. The purpose of the project was to generate and evaluate different concepts of a device that is to be included in a bigger process named Dried Blood Spot testing (DBS) in which dried blood samples are collected and analyzed. The device developed here shall relocate the blood samples from a paper slip, mounted on a

Public transportation gets paralyzed every year when winter conditions occur and the purpose of this thesis has been to summarize experiences from tram cities, mainly in Scandinavia, and suggest solutions to the problems identified. Material was collected from Stockholm, Gothenburg, Norrköping, Oslo, Trondheim, Helsinki and Budapest. Operating the tramway during winter leads to problems specific t

I delar av Danmarks (Sjælland) grundvatten har det hittats nickel- och arsenikhalter över gränsvärdena bestämda av World Health Organization (WHO). Där har mineralet pyrit undersökts och visat sig innehålla dessa ämnen. Förhöjda halter av arsenik har även upptäckts i skånskt grundvatten av Sveriges geologiska undersökning (SGU). Kalkberggrunden i Danmark och Sverige, som har bildats på liknande säThe groundwater in parts of Danmark (Sjælland) is known to exceed the World Health Organizations limits for arsenic and nickel contents in drinking water according to the Danish Geological Survey (Flindt Jörgensen, 2005a; Flindt Jörgensen, 2005b; Stockmarr 2005). In groundwater in Scania the Swedish Geological Survey has found exceeding contents of arsenic. Therefore, this study investigated pyrit

In industrial buildings there is often a need to attach processing equipment and other components to the building’s structure. If the main structure is made of concrete this is usually done by using anchor plates. An anchor plate is composed of a steel plate, fixed to the concrete with two or more concrete fasteners. There is a large variety of fasteners with different mechanical means of oper

Sweden is in a period of change in its establishment of a new welfare system. One of the main reasons is the political power shift from social democratic welfare regime to liberal welfare regime. This change involves, among others, a restructuring of the relationship regarding responsibility in the social welfare, between the public, private and non-government sectors. This is due to how different

The industry of engineered nanoparticles (ENPs) has grown rapidly during the last decade, with for example carbon nanotubes (CNTs) incorporated in high-tech composites and nanosized TiO2 in sunscreens and paint. With an increased potential of human exposure to these novel ENPs, especially during production and handling of nanoparticles, the concern of risks when people become exposed has increased

Internet har under det senaste årtiondet blivit ett modernt inslag i nästan varje människas vardag. Internet ger obegränsade kommunikationsmöjligheter, men det finns också ett antal negativa sidor med internets snabba utveckling i samhället. En av dessa negativa sidor är att folk under den senaste tiden har börjat utnyttja möjligheten att bakom en datorskärm anonymt kränka personer som de kanske i

This study aims to evaluate the potential of a reuse system for furniture, focusing on students in Lund, this study. The study suggests that furniture has a high potential for increased reuse, partly because of its intrinsic, durable characteristics, and partly because of the students’ positive attitude towards second-hand furniture. The study also suggests that necessary features for such a syste
