First laser spectroscopic investigations on atomic selenium are reported. Natural selenium was thermally dissociated in a quartz resonance cell keeping the background pressure of abundant selenium molecules low by differential heating. The 4p35s5S2 level was excited by frequency-tripled pulsed-dye laser radiation at 207 nm. From time-resolved recordings of the fluorescence decay at 216 nm a natura

One of the hallmark findings from behavioral economics is that choices are sensitive to the context they are presented in. However, the strength of such 'framing effects' varies between studies, and some studies fail to find any effect at all. A long line of research has argued that the presence and size of framing effects depend to a large extent on whether people use higher or lower-level mental
A review of existing life cycle assessments on food waste management was made with two main aims. Firstly, to make an overview of the assessments of the global warming potential from the treatment alternatives incineration, landfill, anaerobic digestion and compost in studies reported in literature. Secondly, to identify decisive factors in general and related to system boundary settings in partic
Various modal methods are frequently used to investigate the vibration pattern in construction elements of a building in the low frequency range. The experimental determination of time average transmission and reflection coefficient has been developed for the large scale building structures. In this study, we investigate a mock up of a wall/floor junction. The wave approach is combined with the co
A Scania 13 1 engine modified for single cylinder operations was run using nine fuels in the boiling point range of gasoline, but very different octane number, together with PRF20 and MK1-diesel. The eleven fuels were tested in a load sweep between 5 and 26 bar gross IMEP at 1250 rpm and also at idle (2.5 bar IMEP, 600 rpm). The boost level was proportional to the load while the inlet temperature
This thesis collects contributions to wireline and wireless communication systems with an emphasis on multiuser and multicarrier physical layer technology. To deliver increased capacity, modern wireline access systems such as G.fast extend the signal bandwidth up from tens to hundreds of MHz. This ambitious development revealed a number of unforeseen hurdles such as the impact of impedance changes
During a meeting held in Trento, Italy in March 2017, and organised by the COST Action CHIP ME (IS1303) to discuss about ELSI of genome-editing, many different positions emerged on the possibility to intervene on reproduction and especially on the human embryo. At the time, the Nuffield Council on Bioethics had commissioned a background paper on genome editing, and the corresponding Working Group

The dependence of denitrification and dissimilatory nitrate reduction to ammonium (DNRA) on different electron donors was tested in the nitrate-containing layer immediately below the oxic–anoxic interface (OAI) at three stations in the central anoxic basins of the Baltic Sea. Additionally, pathways and rates of fixed nitrogen transformation were investigated with 15N incubation techniques without
Background: Identification of targetable EML4-ALK fusion proteins has revolutionized the treatment of a minor subgroup of non-small cell lung cancer (NSCLC) patients. Although fluorescence in situ hybridization (FISH) is regarded as the gold standard for detection of ALK rearrangements, ALK immunohistochemistry (IHC) is often used as screening tool in clinical practice. In order to unbiasedly anal
BACKGROUND: Avian malaria parasites are a highly diverse group that commonly infect birds and have deleterious effects on their hosts. Some parasite lineages are geographically widespread and infect many host species in many regions. Bird migration, natural dispersal, invasive species and human-mediated introductions into areas where competent insect vectors are present, are probably the main driv
The molecular and electronic structures of Co(II)-substituted azurin have been investigated using several realistic models of the metal coordination sphere. The geometry of the models was optimized using the hybrid density functional B3LYP method and compared to the structures obtained for similar Cu(II) models. It is found that Co(II) prefers a distorted tetrahedral structure with four strong bon
The chapter discusses the spatial aspects of the increased globalization of innovation, analysing both the region’s role in influencing the propensity of actors to engage and to play different roles in global innovation networks (GINs). Until now, different concepts such as global value chain (GVC), global production network (GPN) and GIN have been used to explain the increase globalization of inn
Estrogen receptor (ER)-positive breast cancer represents the majority (∼70%) of all breast malignancies. In this subgroup of breast cancers, endocrine therapies are effective both in the adjuvant and recurrent settings, although resistance remains a major issue. Several high-throughput approaches have been used to elucidate mechanisms of resistance and to derive potential predictive markers or alt
