Ice observations were made in the Rane River 1974-1978. Observations of formation of ice, growth of ice, critical velocities, hydrodynamic stability, supercooled water, ice production in rapids and breakup were theoretically analyzed. Depending on the water velocity an ice cover formed after 40-100 negative °C-degree-days. The growth of ice took place at a static growth when the water velocity was
Metaphrasis: A Byzantine Concept of Rewriting and Its Hagiographical Products represents a first and authoritative discussion of rewriting in Byzantium. It brings together a rich variety of articles that treat the topic of hagiographical rewriting from various angles.The contributors discuss and comment on different kinds of texts in Greek and other languages, including Apophthegmata Patrum, Passi
Chondroblastoma and chondromyxoid fibroma are benign but locally aggressive bone tumors. Chondroblastoma, a destructive lesion with a thin radiodense border, is usually seen in the epiphysis of long bones. Chondromyxoid fibroma presents as a bigger, lucent, loculated lesion with a sharp sclerotic margin in the metaphysis of long bones. Although uncommon, these tumors can be challenging to manage.
Monitoring insects of different species to understand the factors affecting their diversity and decline is a major challenge. Laser remote sensing and spectroscopy offer promising novel solutions to this. Coherent scattering from thin wing membranes also known as wing interference patterns (WIPs) have recently been demonstrated to be species specific. The colors of WIPs arise due to unique fringy
The emergency department is a stressful environment, in which physicians are required to make fast and accurate diagnostic assessments amidst an ever increasing flood of clinical information, including a growing body of medical knowledge. Meanwhile, the digitization of medical health records in combination with recent breakthroughs in Artificial Intelligence is ushering in a new era of precision m
Background: Interferon-γ release assays (IGRAs) for tuberculosis infection (TBI) cannot distinguish different stages of the TBI spectrum (including spontaneously cleared infection). We investigated patterns of Mtb-specific blood mediators in people with and without TBI during tuberculosis preventive therapy (TPT). Methods: Individuals with likelihood of recent Mtb exposure, aged 15–25 years, with
This chapter examines the relationship between the United Nations (UN) and African troop contributing countries (TCCs). As a continent which has both hosted and contributed to numerous UN peacekeeping missions, Africa has shaped and is shaped by peacekeeping practices. This chapter considers African states' historical presence in UN peacekeeping operations since the 1960s and distinguishes between
Mean motion resonances are a common feature of both our own Solar system and of extrasolar planetary systems. Bodies can be trapped in resonance when their orbital semimajor axes change, for instance when they migrate through a protoplanetary disc. We use a Hamiltonian model to thoroughly investigate the capture behaviour for first- and second-order resonances. Using this method, all resonances of
We present an approach to process scheduling based on an abstract graph representation which captures both data-flow and the flow of control. Target architectures consist of several processors, ASICs and shared busses. We have developed a heuristic which generates a schedule table so that the worst case delay is minimized. Several experiments demonstrate the efficiency of the approach.
Popular Abstract in Swedish Denna avhandling är uppbyggd kring fyra artiklar som berör reglering av gener i B-celler. B-cellerna är en viktig del av vårt immunförsvar, de sköter produktionen av antikroppar som hjälper till att skydda våra slemhinnor och vårt inre från sjukdomsframkallande bakterier och virus. Kroppens försvar mot sådana patogener består av flera delar, inklusive vår hud och våra sEach Ig V-region has its own upstream promoter and the promoter of a mature Ig gene is thereby selected during the V(D)J recombination process. Upon comparison, it is evident that only one transcription factor binding site, the octamer, is preserved within all promoters. The octamer motif and the binding Oct-proteins are crucial for Ig promoter function, but not sufficient for a high level of tran
This study highlights the need to increase our understanding of the interplay between sensor drift and the performance of the automatic control system. The impact from biased sensors on the automatic control systems is rarely considered when different control strategies are assessed in water resource recovery facilities. Still, the harsh measurement environment with negative effects on sensor data
Orkanen Katrina, tsunamin i Indiska oceanen, Lehmankraschen och 11-september attackerna är bara några exempel på sentida händelser som väckt frågor kring vår förmåga att förutse och förstå katastrofrisker. I efterhand är det dock lätt att glömma att vi alltid har ett oändligt antal potentiella scenarier framför oss, men bara ett förflutet, vilket kan få oss att överdriva förutsägbarheten för händeDivision of labor and trade have been prerequisites for the development of welfare societies. Ironically, this specialization has caused a fragmentation of the knowledge necessary to understand risks that may undermine societal safety. This has not only prompted a need for inter-organizational exchange and integration of disaster risk information, it has also prompted a need for understanding how
This paper takes its starting point in the question of how damages for violation through crime are determined by the law. Damages for violation is a type of non-pecuniary damage and the non-pecuniary damages to crime victims is the dominating type of these damages in Swedish tort law. Yet there is a fundamental uncertainty about the computation of damages and what is really meant by "violation" in
Antibody microarray technology has the potential for playing a large roll in identifying serological biomarker panels for personalized medicine. The aim of this thesis, based on four original papers, was to investigate if information in the serum proteome could be extracted and used for diagnostic, classificational, prognostic or treatment predictive purposes in a range of diseases. In two studies
Drawing on results from a survey made at three local social forums held in Sweden, and interviews with activists taking part in the “co-ordination group” of one of these local forums (and to some extent interviews with Swedish local forum activists that visited the World Social Forum 2007 in Nairobi, Kenya), this paper focus on the transnational and the global dimension of activism within the glob
