Allozyme variation was studied in Swedish populations of Silene vulgaris (a widespread weed), S. uniflora ssp. uniflora (restricted to coastal habitats) and S. uniflora ssp. petraea (endemic to Sweden and confined to open limestone habitats). The taxa are diploid, gynodioecious, perennial herbs and showed high levels of within-taxon and within-population gene diversity at four polymorphic loci. Wi

Two morphological races have previously been recognized within the sedge, Carex lepidocarpa, in Sweden. These largely allopatric races are accorded specific status, as C. lepidocarpa s.s. and C. jemtlandica, in Scandinavian floras. A study of allozyme variation in population from 80 Sweden sites supports the morphological evidence for racial differentiation within C. lepidocarpa. The two races dif

Allozyme data were used to assess the genetic structure between 37 sympatric populations of the species-pair Silene vulgaris and S. uniflora ssp. petraea, and to infer levels of intra- and interspecific gene flow in the two species. Silene vulgaris is a geographically widespread weed of disturbed habitats whereas S. uniflora ssp. petraea is endemic to the Baltic islands of Öland and Gotland. On Öl

Relationships between allozyme differentiation, habitat variation and individual reproductive success were examined in local populations of a perennial herb. Gypsophila fastigiata, on the Baltic island of Oland (Sweden). Relatively little (c. 2%) of the total allozyme diversity in this largely outcrossing species is explained by differentiation between sites tens of kilometres apart. The low level

The structure of genetic variation in disjunct Scandinavian populations of Hippocrepis emerus was studied using allozymes and DNA fingerprinting. Variation in the three native regional populations in Scandinavia was compared with that in a recently introduced population in Sweden. In contrast to the recently introduced population, the native Scandinavian isolates of H. emerus showed high levels of

In response to global sustainability challenges, there are multiple public research andpolicy incentives being implemented to support a more sustainable energy system. These are aimed at advancing technology and innovation as well as guiding citizens tochange behaviour. But are those incentives accurately leading to a transition towards amore sustainable energy system and society?Evaluation of the

Labile carbon (C) inputs affect the soil carbon:nitrogen (C:N) ratio and microbial stoichiometric homeostasis, which control the intensity and direction of the priming effect (PE). Here, we clarified how soil microorganisms regulate enzyme production and PE to maintain the C:N stoichiometric balance. Specifically, we conducted an incubation experiment by adding 13C-labeled glucose to four long-ter

Radionuklidterapi är en form av strålbehandling där sjukdom behandlas genom att ett radioaktivt ämne tillförs till kroppen. Typiskt sett består det tillförda ämnet av två sammankopplade komponenter: Dels en radionuklid (radioaktiv variant av ett viss grundämne) och dels ett läkemedel vars egenskaper gör att det tas upp i det sjuka området. Ofta tillförs det radioaktiva läkemedlet via injektion i eRadionuclide therapy (RNT) is a form of radiotherapy that uses unsealed radioactive sources for the delivery of ionising radiation within a patient's body.Radiation dosimetry is not used routinely in all centres, and the RNT field can benefit from more data on pharmacokinetics and absorbed doses (ADs).Consequently, there is a value in developing and investigating methods that facilitates the acqui

Multiple myeloma (MM) is caused by the uncontrolled, clonal expansion of plasma cells. While there is epidemiological evidence for inherited susceptibility, the molecular basis remains incompletely understood. We report a genome-wide association study totalling 5,320 cases and 422,289 controls from four Nordic populations, and find a novel MM risk variant at SOHLH2 at 13q13.3 (risk allele frequenc

The aim of this thesis is to develop a conceptual model for understanding conditions for and outcomes of bootstrapping behaviors. Recent literature on financial bootstrapping in new firms acknowledges the necessity to consolidate and conceptualize the existing knowledge. Yet, the focus and findings of current research remain dispersed and at times contradictory, which might indicate the need for c

Muhammad Hejazi, deputy head of the Iranian Quds Force, is reported to have died of heart disease. However, a mysterious tweet hints that he might have been killed.

Debatten om covid-19 fokuserar främst på medicinska områden som smittspridning, antikroppar och vacciner. Men det finns andra aspekter som glöms bort.Våren 2020 rapporterade Interpol att stora mängder förfalskade covid-19- skyddsprodukter av olika slag var i omlopp. Nu ett år senare har den globala illegala spridningen ökat. Det gäller allt från undermåliga ansiktsmasker till sådant som utger sig

This paper addresses the influence of deteriorating structural system characteristics on the value of structural health monitoring (SHM) before its implementation. The value of SHM is calculated within a recently developed framework utilizing the Bayesian pre-posterior decision analysis modelling the structural system performance, the integrity management, the structural risks and the SHM informat

Supermassive black holes (SMBHs) are found in most galactic nuclei. A significant fraction of these nuclei also contains a nuclear stellar cluster (NSC) surrounding the SMBH. In this paper, we consider the idea that the NSC forms first, from the merger of several stellar clusters that may contain intermediate-mass black holes (IMBHs). These IMBHs can subsequently grow in the NSC and form an SMBH.
