Oranic acid anhydrides (OAAs) are important reactive, low-molecular-weight industrial chemicals which induce allergic rhinitis and asthma in exposed subjects. Specific IgE has been demonstrated in a large proportion of OAA-exposed workers. The characteristics of the OAAs make them excellent model compounds for studies of quantitative structure-activity relationships (QSAR) of allergenicity. In the
Popular Abstract in Swedish Nätverk av nervtrådar påvisades kring koronara artärer och vener från marsvin och människa. Medelst immunhistokemiska metoder demonstrerades olika signalsubstanser i anknytning till dessa nervtrådar och i olika delar av kärlväggen (endotelet, media, adventitia), och det påvisades hur vissa av dessa substanser var lokaliserade i samma vesikler av ovan nämnda nervtrådar. A network of perivascular nerve fibres was demonstrated in coronary arteries and veins from guinea-pig and man. Nerve fibres displaying immunoreactivity to neuropeptide Y (NPY) had a distribution pattern similar to those containing immunoreactivity to tyrosine hydroxylase. Immunoreactivity to substance P and calcitonin gene-related peptide (CGRP) occurred in the same varicose nerve fibres, which w
Popular Abstract in Swedish I detta arbeta har reaktionerna 16O(γ,p)15N och 18O(γ,p)17N studerats med hjälp av reella fotoner. Fotonerna med vilka syrekärnorna har bestrålats har varit i energiområdet 50 - 70 MeV. De utgående laddade partiklarna såsom protoner, deuteroner och tritoner har detekterats med hjälp av två ΔE-ΔE-E teleskop placerade i 70o respektive 110o relativt fotonstrålen. De två 0.A measurement of the reactions 16O(γ,p)15N and 18O(γ,p)17N have been made with tagged photons in the energy range Eγ ≈ 50 – 70 MeV. The protons have been detected in ΔE-E telescopes with silicon strip detectors as ΔE detectors and HPGe crystals as E detectors. Two telescopes have been used with an average angle towards the photon beam of 70 and 110 degrees. The silicon strip detectors have been us
Polyphosphoinositides, the different phosphorylated variants of the phospholipid phosphatidylinositol (PtdIns), are used in a wide array of intracellular mechanisms in eukaryotic cells. The phosphorylation of PtdIns at carbon D4, catalyzed by phosphatidylinositol 4-kinase, is an important step in the synthesis of several of these molecules. The presence of different isoenzymes of PtdIns 4-kinase i
The Energy using products (EuP) directive proposed by the European Commission is often referred to as "the first Integrated Product Policy (IPP) directive". The main purpose of the directive is to ensure the free movement of EuP in the internal market as well as to improve the environmental performance of products throughout their life cycle. Product groups likely to be addressed through the direc
This paper examines references of visual product identity in product design. The perception of identity is the result of a composite experience of the presentational and representational dimensions of the product. As consumers to a large degree create their value perceptions of products and brands based on the design of the product, it is important for companies to understand how perceptions of id
The influence of pH, KCl and temperature on the performance of an Alfa Laval NFT-50 nanofiltration membrane was evaluated by glucose and KCl retention measurements at constant flux. It was found that at constant temperature an increase in pH in the absence of KCl reduced the water permeability, and this was correlated to the electroviscous effect. The selectivity decreased with increasing KCl conc
Popular Abstract in Swedish Omgivningens temperatur är kanske en av de faktorer som i allra störst utsträckning påverkar djur och deras livsmiljö. Detta bottnar givetvis till stor del i temperaturens effekt på naturen. Betänk till exempel årstidsväxlingarna; att vintern blir till vår, och att hösten (i samband med de första snöfallen) allt mer skrider mot ännu en kall och vit vinter bestäms och reTemperature is a property of profound matter in all aspects of animal life, affecting both individual energy budgets and the environments in which animals reside. Thus, a proper understanding of the effects of temperature variation is instrumental in understanding not only animal form and function, but also the structure and dynamics of wild populations. Accordingly, the aims of this thesis were t
The innocuous place of Hungary’s Jews in the historical culture of the country from 1945 to 2004 is an indication that the Holocaust has not set its stamp on this culture. It is noteworthy that in the last decade of the Kádár regime, there was a strong interest in Hungary in the fate of the Hungarians in the territories that had been lost at Trianon. This interest was an important factor in Hungar

In what has been seen as an age of increasing bureaucratisation, did it matter who was close to the monarch? Since the monarch embodied supreme wordly power, the way in which daily life at court was organised was of great importance. One function of the early modern court was, in the words of Geoffrey Elton, to act as a point of contact between monarch and élite. I have chosen to test this hypothe
This book investigates the relationship between the quality of working life (QWL) and competitiveness in the specific context of organisational innovations in Sweden. It proceeds by way of reviewing the literature of both a general theoretical nature on innovations, including Swedish research, and then looks more closely at the empirical evidence on the QWL-competitiveness relationship at the micr
