Group A Streptococcus (GAS) is a significant human pathogen that has developed multipleimmune evasion mechanisms to counter the host immune response. One of these mechanisms involvesthe production of the M protein, which, amongst other things, acts as an anti-phagocytic factor and canbind host proteins. Another is the ability of M protein to bind a human protein called fibronectin (Fn). Thisprotei

This thesis work was done in the SCAN COIN headquarters in Malmö, Sweden. In the work, we investigate the possibility to optimize the product SCAN COIN CashComplete POS. CashComplete is a closed system that makes it easy to pay with notes and coins and get the correct change back. To make CashComplete more attractive in a self-checkout environment the products price must be decreased. This work fo

Popular Abstract in English Imagine you are sunbathing on a sandy beach, while reading the latest Dan Brown book. Once the book is finished, you look at the waves and notice that in one place, they decelerate and become large. Excited by your reading, you imagine that beneath those larger waves there is a ship containing a treasure in it (most likely sunk by the Illuminati during World War II). BuThis thesis describes how photoemission stimulated by an attosecond pulse train (APT) can be used to extract information on electron correlation in simple quantum systems such as atoms. The emission of the electron by an APT induces a reorganization of the electrons remaining in the ion core. This reorganization causes a change in the trajectory of the emitted electron. An infrared (IR) field is u

Popular Abstract in English For several decades the electronic industry has developed towards smaller and smaller electronic components. The idea behind this development is quite simple: Small components have faster response times, which enables faster devices. Also, smaller components make it possible to decrease the size of the devices. A common example is today's mobile phones, that actually arThis dissertation deals with the effects of coherence and correlations on transport through nanostructures. Simulations are mainly performed using the second order von Neumann approach, a method capable of dealing with these effects in the presence of higher order tunneling. We see that such effects can result in various kinds of current suppression as well as efficient thermoelectric devices. Fu

Varför gör vissa bakterier oss sjuka men inte andra? Hur kommer det sig att vissa bakterier lyckas överleva och infektera särskilda delar av kroppen men väldigt sällan andra? Bakterier och människor har evolverat länge tillsammans och har därmed lyckats utveckla specifika angrepps och försvarsmekanismer mot varandra. Det är känt sedan tidigare att några bakterier uttrycker proteiner med förmågan Bacteria and humans have co-evolved since their common existence. They have thereby developed very specific defence and target mechanisms against one another. Understanding the complex biomolecular processes behind these interactions can be of great use for developing treatments against bacterial diseases. The aim of this thesis project was to verify, and introduce a model for understanding, the i

När medier publicerar upphovsrättsligt skyddat material uppstår ett intressant och mångsidigt juridiskt problem. Upphovsinnehavaren har å ena sidan ensamrätt på hur alstret får utnyttjas. Media är å andra sidan ett kontrollorgan med uppgiften att informera allmänheten, särskilt i politiska sammanhang. Följaktligen har det införts upphovsrättsliga inskränkningar som i vissa fall ger medier rätt attMedia usage of copyright protected material creates an interesting and versatile legal problem. On the one hand, right holders have an exclusive right to the usage of their work. On the other hand, the importance of media freedom in a democratic society cannot be overstated. Journalists have a right and duty to inform on matters of public interests, especially political ones. Consequently, there a

It has often been argued that money and modern monetary economies have occasioned a comprehensive rationalisation of society. Money has often been viewed as being socially destructive, while it is said that the modern monetary economy has had inescapable consequences for society, culture, and people’s daily lives. This thesis considers the introduction of computerised systems for handling digital

Popular Abstract in English This thesis is concerned with the efficient generation of ultra-short light pulses, far beyond the visible spectral range. Such light pulses can reach durations below 100 attoseconds, where one attosecond is one billionth of a billionth of a second. Why do we want to generate such extreme light pulses? Our knowledge of basic processes in physics and chemistry is to a High-order harmonic generation (HHG) provides the basis for attosecond light sources delivering coherent pulses in the extreme ultraviolet spectral region. Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. However, the rather low efficiency of the HHG process, which implies a limited pulse energy and repet

Popular Abstract in English Life on earth has evolved countless forms, beautiful shapes and colors as well as astonishingly complex systems. Remarkably, all living creatures consist of cells, which themselves are build from the same basic set of molecules, most importantly nucleic acids (RNA and DNA), lipids and proteins. The latter are large macromolecules that fulfill a vast number of tasks; theThe three-dimensional structure of protein is encoded in its amino acid sequence. Modern structure prediction algorithms make it possible to predict the structure of small proteins using sequence information alone. We used the Fold-and-Dock algorithm, which is part of the Rosetta macromolecular modeling suite, for de novo structure prediction of coiled-coil proteins. Members of this protein family

Questions about institutional stability and change are critically important for any understanding of political institutions. The field of Historical institutionalism in political science has described, studied and theorized institutions for decades. One of the most recurring concepts utilized in the explanation of institutional stability is path dependence, describing theoretical and empirical mec

Popular Abstract in Swedish Patienter som drabbats av Parkinsons sjukdom (PD) saknar förmågan att medvetet kontrollera sina rörelser. Livslång medicinering krävs, vilket lindrar symptomen och leder till att rörelsemönstret förbättras, men med varierad effektivitet. Trots att de läkemedel (t ex L-DOPA) som finns tillgängliga idag har fantastisk effekt, minskar deras effektivitet i takt med att sjukParkinson’s disease (PD) is a neurodegenerative disorder characterised by motor deficits such as slowness in movement, difficulty in initiating movement and tremor at rest. The cause of these motor symptoms is the selective loss of mesencephalic dopaminergic (mesDA) neurons, located in the substantia nigra (SN). These neurons project axons to the striatum where they release dopamine, a neurotransm

Popular Abstract in Swedish I Big Bang skapades 3 grundämnen: H, He, och spår av Li. Alla andra grundämnen har bildats i stjärnor. Lågmassiva stjärnor som vår sol kan genom kärnreaktioner skapa grundämnen upp till och med syre i det periodiska systemet, medan mer massiva stjärnor kan skapa grundämnen ända upp till järn. Tyngre grundämnen än järn produceras in slutstadierna av stjärnornas liv, tillAll the elements heavier than Li are created during stellar evolution. Even if our knowledge of this process is good, many questions still remain. For instance, the odd-Z iron-peak elements Sc, V, Mn, and Co together with neutron-capture elements Sr, Zr, La, Ce, Nd, Sm, and Eu have still unclear production sites because theoretical models and observational evidences are not in agreement.
