In retrospective radon measurements, the 22-y half life of Pb-210 is used as an advantage. Pb-210 is often considered to be relatively immobile in glass after alpha recoil implanted by Rn-222 progenies. The diffusion of Pb-210 could, however, lead to uncertain wrong retrospective radon exposure estimations if Pb-210 is mobile and can escape from glass, or lost as a result of cleaning-induced surfa
The participation of transnational actors in global policymaking is increasingly seen as a means to democratize global governance. Drawing on alternative theories of democracy and existing empirical evidence, we assess the promises and pitfalls of this vision. We explore how the structuring and operation of international institutions, public-private partnerships, and transnational actors themselve
Four high-spin collective bands have been populated in Er-154(68)86 via the Pd-110(Ti-48, (4)n gamma)Er-154 reaction. Average transition quadrupole moments Q(t) have been measured for three of the bands by using the Doppler-shift attenuation method. The strongest band has a value of Q(t) = 11.0 +/- 1.0 e b, similar to values found recently for four triaxial strongly deformed (TSD) bands in Er-157,
Prophylaxis and treatment with antiretroviral drugs, a consequent low viral load, and the use of elective Caesarean section, are factors that radically decrease the risk of HIV transmission from mother to child during pregnancy and delivery. The availability of new antiretroviral drugs, updated general treatment guidelines and increasing knowledge of the importance of drug resistance, have necessi
In this article I show how aesthetic disciplines, to which musicology belongs, have suffered from a crisis of creativity for the past decade or so. By crisis of creativity I mean the development of new theories, which can contribute to new knowledge about music, from both historical and contemporary prespectives. With help from theories that normally lies outside of the institutional discourse of
A proactive strategy to respond effectively to health impacts related to climate variability, particularly within vulnerable populations, is of vital importance. Such a strategy can be attained if health officials have a deep understanding of how climate variability affects human health and if the resources available for the health care sector are sufficient. This study assessed the perceptions an
Near-haploid chromosome numbers have been found in less than 1% of cytogenetically reported tumors, but seem to be more common in certain neoplasms including the malignant cartilage-producing tumor chondrosarcoma. By a literature survey of published karyotypes from chondrosarcomas we could confirm that loss of chromosomes resulting in hyperhaploid-hypodiploid cells is common and that these cells m
With the aim to reconsider lifestyle values in relation to economic rationality in small tourism and hospitality businesses, we focus on the “commercial home” as a site where boundaries between personal and commercial values are constantly performed in practice. Through an interactionist analysis of the narrative of a B&B and gallery owner, we illustrate the emergence of intimacy as a commerci
The solvolysis of substituted benzoyl chlorides is sensitive both to substituent electronic effects and to medium effects. The solvolysis reactions of substituted benzoyl chlorides have been analyzed in the presence of nonionic micelles. The reaction is inhibited or catalyzed depending on the reaction mechanism, dissociative or associative, respectively. The micellar effects observed can be relate
Background. Although the clinical importance of demonstrating the presence of anti-glomerular basement membrane (anti-GBM) antibodies is well established, less is known concerning the clinical utility of measuring the levels of autoantibodies. Two conformational epitopes of anti-GBM antibodies have been defined at residues 17-31 and 127-141 of the alpha 3(IV)NC1 domain of type IV collagen [alpha 3
Proteins from halophilic microorganisms thriving at high salinity have an excess of charged carboxylate groups, and it is widely believed that this gives rise to an exceptionally strong hydration that stabilizes these proteins against unfolding and aggregation. Here, we examine this hypothesis by characterizing the hydration dynamics of a halophilic model protein with frequency- and temperature-de
Popular Abstract in Swedish Dödligheten i skador i Sverige har under de senaste årtiondena minskat, en minskning som idag dock har planat ut. Antalet dödade i transportolyckor och i arbetsplatsolyckor i Sverige har minskat under de senaste 40 åren vilket kan ses som ett resultat av ett effektivt säkerhetsarbete. När det gäller fallolyckor så har däremot andelen som dör av sina skador ökat markant Injuries are often associated with long-term suffering and lowered functioning, and personal injuries impose a huge burden on medical care and health services in addition to the costs associated with impaired functional ability. Each year in Sweden, falling accidents are experienced by a third of those aged 60 or over and half of those aged 80 or over, while injuries from traffic accidents still a
Abstract Multimodal learning materials are frequently met in education assuming enhanced learning outcomes. This study examined whether contrasts in such materials are likely to support reading comprehension for all readers. Young adults (n=46) met either text-only or text+picture material. Participants (19 with low phonological awareness [PA] and 27 controls with high PA) thereafter answered open
We investigate four different methods for background estimation in calcium imaging of the insect brain and evaluate their performance on six data sets consisting of data recorded from two sites in two species of moths. The calcium fluorescence decay curve outside the potential response is estimated using either a low-pass filter or constant, linear or polynomial regression, and is subsequently use
Swedish children’s use of the headshake from 18 to 30 months shows a developmental progression from rote-learned coordination with speech to increasingly more flexible and productive coordination with speech. To deal with these observations, I introduce the concept of multimodal constructions in order to extend usage-based approaches to language learning and construction grammar into the kinetic d
Swedish guidelines on treatment of hyperlipidemia recommend higher cut-off levels for initiating treatment than do American guidelines, but are virtually identical for instituting and performing therapy. The aim of this study was to compare family physicians' reported practices in Sweden and Minnesota. We selected random samples of family physicians in southern Sweden and Minnesota for telephone i
