The Swedish Academy of Sciences was founded in 1739. The article presents and discusses the explicit language policy of the academy and analyzes some aspects of the language and rhetoric of the transactions (in Swedish) of the academy:textual organization, objectivity, rhetorical devices, lexical apparatus, syntactic machinery and techniques of presentation. Special interest is devoted to the tran

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

Objective The objective of this article is to determine if maternal obesity is associated with an increased risk of Down syndrome in the offspring and whether the risk estimates for trisomy 21 based on combined screening is affected by maternal body mass index (BMI). Methods Study group I consisted of a nationwide cohort of 1 568 604 women giving birth; outcome was infants born with Down syndrome

Friction is an important phenomenon in everyday life. All children are familiar with playground slides, which may thus be a good starting point for investigating friction. Motion on an inclined plane is a standard physics example. This paper presents an investigation of friction by a group of 11-year olds. How did they plan their investigations? What aspects of friction could they discern? What un
