In everyday listening, speech perception occurs under conditions where acoustic information may be incomplete or ambiguous, including background noise and variability in signal quality. Listeners must navigate ambiguous, masked or rapidly unfolding speech signal in order to comprehend spoken language. While prediction has been widely discussed and acknowledged in speech perception, less is known a
Metal ions are essential cofactors for precursor tRNA (ptRNA) processing by bacterial RNase P. The ribose 2'-OH at nucleotide (nt) –1 of ptRNAs is known to contribute to positioning of catalytic Me2+. To investigate the catalytic process, we used ptRNAs with single 2'-deoxy (2'-H), 2'-amino (2'-N), or 2'-fluoro (2'-F) modifications at the cleavage site (nt –1). 2' modifications had small (2.4–7.7-
An increasing number of studies describe moving hybrid zones. This raises the issue of their actual frequency and emphasizes the need for methods that enable the detection of zone movements without historical records. Asymmetric introgression, usually considered as a signature of geographical shift, might be misleading when applied to mitochondrial or potentially non-neutral markers. We investigat
Deep cuts in carbon emissions to avoid dangerous climatic change will require fundamental transformations of the energy and transport systems. This is an enormous challenge for society and the political system. In order to tackle this challenge, we argue that it will be necessary to develop new institutions and institutional practices that address and give priority to long-term climate policy obje
Various forms of supply chain management (SCM) research have been carried out in many different manufacturing or industrial settings over the last decades. However, less research exist concerning supply chain management in the service industry. Yet, definitions of supply chain management as they pertain to the service industry are only slightly different than those definitions of SCM in manufactur
Latin America attends currently to the construction of a paradigm of rural development based on the potentiality of the territory to encourage processes of rural wellbeing. Some international studies relating rural development to territory from an institutional perspective have recently come out, greatly contributing to the construction of a territorially based rural development in the region. The
Soot emissions from diesel engines are the net result of two competing processes: soot formation and soot oxidation. Previous studies have shown poor correlation between soot formation rates and the soot emissions. This article presents a systematic study of a number of parameters affecting soot oxidation rate and how it correlates with the soot emissions. An optical heavy-duty engine is used in c
Hydrogen refueling station is one of the most important parts for the hydrogen energy utilization. In this paper, a novel high multi-stage pressure reducing valve (HMSPRV) is proposed, which can be used for hydrogen stable decompression in hydrogen refueling station. In HMSPRV, the inner and outer porous shrouded valve core is used to replace piston valve core to achieve the first-stage throttling
The part-load behaviour of combined cycle power plants (CCPP) equipped with post-combustion CO2 capture is analyzed. Different CCPP configurations are compared, including single-, dual- or triple-pressure level steam generators. The gas turbine is a single shaft unit using the variable guide vanes and fuel flow to control the load. The 90% CO2 capture is achieved using monoethanolamine (MEA 30%wt)
Animal movement acts at multiple scales: it can shape the destiny of individuals and populations, govern community and ecosystem structure, and influence evolutionary processes and patterns of biodiversity. Recent technological advances, such as the revolutionary developments in tracking technology and remote sensing, provide fresh insights and the possibility to collect detailed data on where and
The purpose is to explain the value of utilising tracking data for material flow control purposes in different supply chain areas. The research methodology is based on a literature review and a case study of a distribution system originating from an international paper manufacturer. The distribution system in the analysis started RFID technology adoption more than ten years ago and has developed
In this chapter, we address intersections of Science and Technology Studies (STS) and International Relations Theories (IR) by looking at how Austrian science, technology & innovation (STI) policy makers and related stakeholders envision and enact a close relationship between China and Austria in the field of green technologies. Analytically, we draw on the concept of ‘sociotechnical imaginari
Abstract What are the pedagogical impacts of internationalisation on the development of higher education in Europe? How can we proceed in this process and take a pedagogical stance on the issue? This theoretical paper is partly based on a series of empirical studies conducted by the author, investigating students’ and teachers’ experiences and understanding of an internationalised educational cont
In 2008-2009 Lund University, Sweden, took part in two European benchmarking projects on eLearning, E-xcellence+ (EADTU) and Benchmarking eLearning exercise2009 (ESMU) as part of the University’s policy for quality assurance and quality enhancement of education. Among the aims were · to adopt, as the first Swedish university, a benchmarking process according to quality criteria of eLearning formul
Popular Abstract in Swedish Människans kropp består av celler som byggs upp av komponenter som DNA, proteiner, lipider och polysackarider. I DNA finns den genetiska informationen lagrad som gör att kroppen kan fungera. Informationen i DNA omvandlas till proteiner som deltager i cellens biokemiska processer. DNA finns i olika former, dels genomiskt DNA och dels en mindre cirkulär form som kallas plThe main scope of this thesis has been to study and develop new purification methods and also to further develop existing methods for purification to enhance their efficacy. Important parameters in the development of the methods are that they should be suitable for scale-up and possible to be integrated into recovery processes. The studies in this thesis describe that a hydrophobic peptide tag ca
Popular Abstract in Swedish I Sverige drabbas årligen så många som 100.000 personer av benbrott, höftfrakturer och sjukdomar, som kan kopplas till benskörhet. Under normalt åldrande ändras benets struktur och täthet vilket ökar risken för benbrott. Man vet att förändringarna förorsakas av förändringar i skelettets förmåga att ombildas. Under hela livet byts benvävnaden successivt ut och ersätts av
We describe the possibility to create solid-like protein samples whose structural and mechanical properties can be varied and tailored over an extremely large range in a very controlled way through an arrested spinodal decomposition process. We use aqueous lysozyme solutions as a model globular protein system. A combination of video microscopy, small-angle neutron and X-ray scattering and reverse
Popular Abstract in Swedish När en människa möter döden i sin närhet gör sig ofta grundläggande frågor kring livet och döden påminda. I sådana situationer söker många människor sig till kyrkan för att ta avsked av sina anhöriga. Begravningsgudstjänsten är ett av de starkaste banden mellan svenska folket och Svenska kyrkan. I ”Gå vi till paradis med sång” studeras förutsättningar för ett möThe purpose of this thesis is to shed light upon the function of hymns in Church of Sweden funeral services in the 1990s. The funeral service is one of the strongest links between the Swedish people and the Church of Sweden. Since this service can be seen as an essential meeting-place between people and their needs in a mourning process and the Church and its message of faith in this situation, th
