We present the results of isotope-geochronological study of metasedimentary rocks of the Bolshecheremshanskaya Formation of the Volgo-Uralian segment of the East European Craton carried out to identify their protoliths. 16 samples of high-alumina gneisses from well cores were studied using the Sm-Nd isotope method and T-Nd(DM) model ages. Accessory zircons were selected from rocks with the most an
Agricultural intensification is recognised as a major driver of biodiversity loss in human-modified landscapes. Several agro-environmental measures at different spatial scales have been suggested to mitigate the negative impact of intensification on biodiversity and ecosystem services. The effect of these measures on the functional structure of service-providing communities remains, however, large
Resilience of ecological communities to perturbation is important in the face of increased global change from anthropogenic stressors. Monitoring is required to detect the impact of, and recovery from, perturbations, and before-after-control-impact (BACI) analysis provides a powerful framework in this regard. However, species in a community are not observed with perfect detection, and occupancy an
Natural enemies such as predatory arthropods and parasitoids have the potential to suppress pest species and provide the ecosystem service biological control. When predicting the potential of biological control in agriculture it is important to give evidence on how agricultural management influence the abundance and functions of the natural enemies. In this study we examined whether managements pr
Hummingbirds are specialized hoverers for which the vortex wake has been described as a series of single vortex rings shed primarily during the downstroke. Recent findings in bats and birds, as well as in a recent study on Anna's hummingbirds, suggest that each wing may shed a discrete vortex ring, yielding a bilaterally paired wake. Here, we describe the presence of two discrete rings in the wake
Genome-wide association studies have identified 32 loci influencing body mass index, but this measure does not distinguish lean from fat mass. To identify adiposity loci, we meta-analyzed associations between similar to 2.5 million SNPs and body fat percentage from 36,626 individuals and followed up the 14 most significant (P < 10(-6)) independent loci in 39,576 individuals. We confirmed a previou
Total and cause specific mortality and cancer morbidity were studied among 1929 asbestos cement workers with an estimated median cumulative exposure of 2.3 fibre (f)-years/ml (median intensity 1.2 f/ml, predominantly chrysotile). A local reference cohort of 1233 industrial workers and non-case referents from the exposed cohort were used for comparisons. The risk for pleural mesothelioma was signif
Spinach thylakoids were separated into grana core, grana margin, and two different stromal lamella fractions in the absence of detergents. The levels of all light-harvesting chlorophyll a/b-binding (LHC) proteins were determined in all fractions, and were normalised to the amount of Photosystem I (PS I) and Photosystem II (PS II) centres. PS Iβ in the stroma lamellae was found to have a full compl
OBJECTIVES: The referrals of elderly for cardiac surgery are increasing. The aim of this retrospective study is to review the long-term survival and to identify causes of late death in elderly after cardiac surgery. DESIGN: Between 1990 and 1993, 130 octogenarians underwent cardiac surgery in our department. A majority (88%) had elective surgery. One hundred and nine patients (84%) were in New Yor
The purpose of this study is to assess QT interval measurements from the EASI 12-lead ECG as compared to the standard 12-lead ECG. The QT interval was automatically measured in simultaneously recorded standard and EASI 12- lead ECGs, using a validated wavelet-based delineator. The agreement between the two sets of measurements was quantified both on a lead-by-lead basis and a multilead basis. The
All vårdpersonal bör ges grundläggande kunskaper om smärtsinnet, reaktioner på smärta samt behandling av olika typer av smärta. Sjuksköterskor ska dessutom ha god kännedom om tekniker för smärtskattning, om psykologiska faktorers betydelse och om traditionella smärtstillande läkemedels kliniska användning (SoS-rapport 1994:4). Syftet med denna studie var att undersöka förekomst, innehåll och mål f
Bristande handhygien inom vården är ett globalt problem och det finns ett samband mellan låg följsamhet av rutiner för handhygien och förekomsten av vårdrelaterade infektioner. Syftet med denna studie var att undersöka sjuksköterskors syn på orsaker till bristande handhygien samt vilka möjligheter som finns för förbättringar. För att undersöka detta användes ett frågeformulär med öppna frågor som
Sweden’s grocery distribution is routed through a limited number of upstream hubs and relies on corridors and ferry links. When disruptions affect a hub or a critical link, reallocations propagate fast and travel times increase, with some areas losing coverage temporarily. Decentralising the whole system is costly, so targeted resilience options must be evaluated. The purpose of this thesis is to
Tuvalu, a low-lying Small Island Developing State (SIDS), is projected to face severe challenges due to climate change. Most notably, permanent inundation or the permanent loss of habitable land due to sea-level rise. This thesis investigates how Tuvalu has framed climate change as an existential security threat in its international discourse from 2021 to 2023. Applying an adapted version of secur
This work explores the catalytic activity of decavanadate (V10)-based catalysts in the selective oxidation of ethylbenzene (EB), a model compound of lignin-derived molecules, under mild conditions. The goal is to assess the catalytic efficiency, product selectivity, and the influence of counter-ions on activity through systematic testing of parameters such as temperature and catalyst loading. Addi
