The sFLASH project at DESY is an experiment to study direct seeding using a source based on the high-harmonic generation (HHG) process. In contrast to SASE, a seeded FEL exhibits greatly improved longitudinal coherence and higher shot-to-shot stability (both spectral and energetic). In addition, the output of the seeded FEL is intrinsically synchronized to the HHG drive laser, thus enabling pump-p
Malignant melanoma is one of the most aggressive tumors which often gives metastasis to distant organs thereby limiting the chances of survival. Brain metastasis occurs in nearly half of the advanced tumors. In order to improve outcome early diagnosis is important. The discovery and better understanding of genetic and epigenetic changes is essential for developing new effective therapies, which ca
Medical students’ access to clinical supervision when rotating through hospital workplaces and the quality of that supervision are and have been an area of growing professional and societal concern. Increased training measures targeted at supervising physicians have been suggested to address this issue. Traditionally, such training has focused on offering physicians opportunities to develop as sup
Several studies demonstrate the value of residents’ voices in the place branding process, however, relatively little is known about how residents experience participating in place branding campaigns and the consequences for place identity. This chapter explores the question of whether participatory branding initiatives could potentially lead to more inclusionary representational spaces in the city
Dispersal is important for determining both species ecological processes, such as population viability, and its evolutionary processes, like gene flow and local adaptation. Yet obtaining accurate estimates in the wild through direct observation can be challenging or even impossible, particularly over large spatial and temporal scales. Genotyping many individuals from wild populations can provide d
The number of adult bicycle helmet users in Sweden has stayed over the years relatively stable around 20 % [1]. In Europe the number of helmet users varies between 1 and 40 % depending on country. Research has shown that the use of helmet considerably diminishes head injuries in the case of traffic accidents [2]. In spite of that it is not fully clear what are the main factors why only a small num
In the assessment of thermal comfort in buildings, the use of the Predicted Mean Vote (PMV) model is very popular. For this model, data on the climate, on clothing and on metabolic heat production are required. This paper discusses the representation and measurement of clothing parameters and metabolic rate in the PMV context. Several problems are identified and for some of these solutions are pro
A significant part of the cost of a construction project, up to 90%, consists of purchased goods and services. Suppliers thereby have a large impact on the quality, price and time of projects. Purchasing management is therefore important for the outcome of a project. The aim of research covered by this thesis is to describe and analyse purchasing management and its interrelation with the supplier
Denna studie handlar om att experimentellt karakterisera ett materietillstånd som existerade under de första miljondelarna av en sekund under Big Bang, som vi kallar för Kvark-Gluon-Plasma. Med stora partikelacceleratorer som Large Hadron Collider (LHC) vid CERN, kan vi genom kärnkollisioner med mycket hög energi nå så pass extrema temperaturer och densiteter att vi kan återskapa och studera dettaIn high energy heavy ion collisions, the QCD matter undergoes a phase transition to a hot and dense strongly coupled Quark Gluon Plasma, where quarks and gluons are deconfined in a volume of nuclear dimensions. At intermediate pT, 2 < p T < 8 GeV/c, a decoupling from pure hydrodynamical flow is observed, most noticeable in central collisions, demonstrated by the peak in the ratio of baryons to mes
UNLABELLED: Transformation of genetic material between bacteria was first observed in the 1920s using Streptococcus pneumoniae as a model organism. Since then, the mechanism of competence induction and transformation has been well characterized, mainly using planktonic bacteria or septic infection models. However, epidemiological evidence suggests that genetic exchange occurs primarily during pneu
Computer simulation and modelling was used to simulate a real time environment in preparative chromatography to evaluate the performance of three different strategies for pooling control for different levels of robustness. The pooling problem was based around a separation case where three different insulin species were to be separated while disturbances to the modulators potassium chloride, ethano
Recent studies have paid strong attention to the field of brand extension, whilst comparatively limited research has focused on line extension and the reciprocal effects on the brand. Barely any attention has been paid to the effect of green product launches on brand evaluation in an automotive context or the influence of the actual awareness for the extensions. This thesis examines the role of Ne
Syftet med examensarbetet är att hjälpa ett företag med att införa standardlittera för deras prefabricerade betongelement som ingår i deras Konceptet. Införandet av standardlittera ska resultera till att återfinna och gruppera deras betongelement i CAD-systemen. We did our thesis project at one of the most prestigious Swedish construction companies. We have examined the possibilities of doing sand
The Gaia satellite, to be launched in August 2012, will measure highly accurate absolute parallaxes of hundreds of millions of stars. This is done by comparing parallactic displacement of stars in different parts of the sky. The accuracy of this method highly depends on the stability of the so-called basic angle between the two fields of view of the Gaia instrument, and periodic variations could l
The proportion of public procurement is nowadays more than substantial; it amounts to all the goods and services that the State, perceived as both: central and local administrations, demands in order to assure the effective and sustainable functioning of the society. Moreover, as the procurement procedures aim at simultaneously achieving best value for money and high standards in non-financial mat
Denna uppsats har till syfte att undersöka vilka likheter och skillnader som finns vid valet av lekmannadomare till brottmålets första instans i Sverige och Tyskland. Mer specifikt undersöks då de valbarhetskriterier som uppställs på de personer som ska tillsättas som lekmannadomare samt hur valet av dem är reglerat i de båda länderna. I och med att arbetet är en komparativ studie undersöks försThe purpose of this essay is to find out what similarities and differences exist for the election of lay judges for the court of first instance for criminal cases in Sweden and in Germany. More specifically the legislation concerning the vote eligibility requirements of the lay judges and the legislation on how the elections of the lay judges are to be carried out are studied. Since the essay is
