Charged particles and photons have been measured in central Pb + Pb collisions at 158 A GeV in a common (eta-phi)-phase space region in the WA98 experiment at the CERN SPS. The measured distributions have been analyzed to quantify the frequency with which phase space regions of varying sizes have either small or large neutral pion fraction. The measured results are compared with VENUS model simula
The medium-induced one-gluon radiation spectrum off a massive quark-antiquark (q (q) over bar) antenna traversing a colored QCD medium is calculated in this contribution. The gluon spectrum off the antenna computed at first order in the opacity expansion is collinear finite but infrared divergent, which is different from the result obtained from an independent emitter which is both infrared and co
This thesis describes experimental studies that aim to stabilise and optimise laser-based particle accelerators. The technique is called laser wakefield acceleration, where electric fields of the order of 102 GV/m accelerate electrons to high energies (⇠102 MeV) over mm-distances in laser-produced plasmas. Among the prerequisites for this acceleration technique to produce electron beams are laser
Introduction: Messenger RNA (mRNA) changes in the small intestine in response to acute mesenteric ischaemia (AMI) could offer novel diagnostic possibilities, but have not been described. The aim was to characterize the mRNA response to experimental AMI. Materials and methods: Twelve pigs underwent catheterisation of the superior mesenteric artery with injection of polivinylalcohol embolisation par
In high-elevation streams of western Colorado, mayflies (Baetis bicaudatus) develop taster, but mature at a smaller size where trout are present compared to streams where fish are absent. These life history traits reduce the time of larval exposure to trout predation, but Cost reduced fecundity. We designed a field experiment involving manipulation of whole streams to determine whether these chang
Objective:To study the effect to recommend no snacks vs three snacks per day on 1-year weight loss. The hypothesis was that it is easier to control energy intake and lose weight if snacks in between meals are omitted.Subjects/Method:In total 140 patients (36 men, 104 women), aged 18-60 years and body mass index>30 kg/m(2) were randomized and 93 patients (27 men, 66 women) completed the study. A 1-
OBJECTIVES: Despite the recent introduction of new peroral drugs as well as neurosurgical methods for Parkinson's disease, treatment of late stage parkinsonian patients remains difficult and many patients become severely handicapped because of fluctuations in their motor status. Injections and infusions of apomorphine has been suggested as an alternative in the treatment of these patients, but the
Pregnancy in a rudimentary horn of a bicornuate uterus is a rare and often fatal event. A case is presented of such a pregnancy detected in the second trimester routine ultrasonographic examination.
This essay presents a detailed analysis of the music and its relations to gameplay, meaning and narrative in the interactive digital game Journey. Taking as its foundation multiple thorough playthroughs of the game, observation and questioning of test subjects has been conducted for greater perspective and objectivity. Combining theories from hermeneutic musicology, narrative ludology and aesthet
The course Software Development for Technical Systems at the division of Structural Mechanics teaches students techniques for implementing finite element applications with both user interface and computational code. Currently Borland Delphi environment is used for the user interface and Fortran is used for the computational part. This master’s thesis is an effort to study methods of integrating Fort
The thesis addresses adoption of conservation agriculture in the northern Mozambican province Nampula. In a situation of food insecurity and increasing pressure on land with soil erosion and reduced yields as a result, conservation agriculture is promoted as an agriculture approach which is environmentally sustainable and which also has potential to improve farmers’ livelihoods. The adoption of co
The AKP ’s proactive foreign policy and the decline of EU-Turkey and US-Turkey relations, along with Turkey’s strengthening ties with its Eastern neighbors, has sparked a heated scholarly and media debate about the axis shift of Turkish foreign policy—from the West to the East. The purpose of the present thesis is to analyze if the arguments of the axis shift supporters are grounded enough to prov
High levels of biodegradable dissolved organic carbon can affect odor, taste, color and chemical oxygen demand of distributed drinking water as a consequence of bacterial growth (Frias et al, 1995; Escobar, I.C. and Randall, A.A., 2001). The water industry would be able to improve the quality of distributed drinking water if spatial and temporal variations of BDOC could be mapped in the distributi
Gaussian to top-hat beam shaping is widely used today in areas of cutting, welding, and laser patterning. Typically, single-mode solid state lasers are used whose Gaussian intensity distribution is transformed into a top-hat. In this thesis the transformation is applied in a single-mode fiber connector, where the aim is a uniform intensity distribution of the emerging light from the connector. Thi
The world we live in today has become more complex, turbulent and unpredictable than ever before. One of the main reasons for this is the emergence of the digital transformation and everything that comes with it, from technological advancements in artificial intelligence and robotics to sharing platforms and the Internet of Things. This dynamic environment is often addressed with the acronym VUCA
