Land-use change is a major driver of biodiversity loss worldwide. Although biodiversity often shows a delayed response to land-use change, previous studies have typically focused on a narrow range of current landscape factors and have largely ignored the role of land-use history in shaping plant and animal communities and their functional characteristics. Here, we used a unique database of 220,000
Introduction: Using a sum score based on a three-graded response scale for the activities of daily living staircase has previously been found to increase the statistical power compared to dichotomized responses when assessing longitudinal changes in activities of daily living. We aimed to investigate if the statistical power could be further increased by using a four-graded scale. Methods: We used
Diffusion MRI yields parameters sensitive to brain tissue microstructure. A structurally important aspect of this microstructure is the myelin wrapping around the axons. This study investigated the forward problem concerning whether water exchange via the spiraling structure of the myelin can meaningfully contribute to the signal in dMRI. Monte Carlo simulations were performed of a system with int
The present study evaluates the effect of water and acetic acid washing on the chemical composition of spruce bark in-depth. Also, washing with steam explosion condensate (SEC) was investigated which is a novel attempt. The leaching kinetics of troubling elements (TE) was studied to understand the leaching behavior of TEs and for upscaling the process. Furthermore, to study the ash transformation
The genetic basis of bird migration has been the focus of several studies. Two willow warbler subspecies (Phylloscopus trochilus trochilus and Phylloscopus trochilus acredula) follow different migratory routes to wintering grounds in Africa. Their breeding populations overlap in contact areas or “migratory divides” located in central Scandinavia and in eastern Poland. Earlier analyses demonstrated
Conservation efforts have mainly been focused on depleted species or populations, but many formerly reduced marine mammal populations have recovered to historical abundances. This calls for new management strategies and new models for ecological risk assessment that incorporate local density dependence and multiple environmental stressors. The harbor seal metapopulation in Swedish and Danish water
Objectives: The objective was to investigate the prevalence of mothers who experienced pain during breastfeeding in the early postnatal period and to describe associated factors. Methods: Medical records of 987 mothers and their babies were scrutinized. Chi-square Test, McNemar's test, and relative risk with a 95% confidence interval were applied for analysis. Results: During the in-hospital postn
Background: Severe asthma has an acknowledged impact on health-related quality of life (HRQOL) and is associated with substantial health care costs. This study aimed to investigate the patients’ own experiences of the disease, perceptions of HRQOL, and awareness of disease management. Methods: This study included severe asthma patients in Sweden and Denmark. A quantitative Web-based survey and qua
Previously, microRNA‐100 (miR‐100) and its putative mRNA target, insulin‐like growth factor receptor‐1 (IGF1R) were identified as differentially and inversely expressed in bovine longissimus dorsi (LD) muscles with divergent intramuscular fat (IMF) content by our group. While IGF1R signaling is implicated in myogenesis and muscle lipid metabolism, the underlying regulatory mechanisms are poorly un
Phase-pure crystalline micropowder samples of BaGeF6 were prepared and studied under excitation by tuneable synchrotron radiation and 10 keV electron beam. Time-resolved photoluminescence emission and excitation spectra and a set of single emission decay curves were recorded at 7 K for the exciting photon energy region of 4.3–45 eV. Several intrinsic emissions were revealed in BaGeF6 and their ori
Buildings account for a signifi cant proportion of the energy use thatgenerates greenhouse gases and consequently drives the ongoing climatechange. As the population of the world increases, the need for buildingsincreases, while the energy use needs to decrease. A reduction in energyuse and increased use of renewable energy are important measures forclimate change mitigation. A fi rst step in decr
Iron-centered N-heterocyclic carbene compounds have attracted much attention in recent years due to their long-lived excited states with charge transfer (CT) character. Understanding the orbital interactions between the metal and ligand orbitals is of great importance for the rational tuning of the transition metal compound properties, e.g., for future photovoltaic and photocatalytic applications.
The European Spallation Source, ESS, is a neutron research facility under construction in Lund, Southern Sweden. The Facility will produce neutrons by spallation, using a powerful linear accelerator to deliver protons to a tungsten target. In addition to the desired neutron production, a long list of radionuclides will be created as by-products of the nuclear reaction inside the target. The Swedis
Polycrystalline cubic boron nitrides (PcBN) have been increasingly used together with PVD coatings, mainly for hard turning operations. Within this context, effectiveness of coated PcBN as cutting tool is usually addressed by evaluation of its machining performance. Meanwhile, studies aiming to assess and understand the correlation between microstructural features and mechanical behaviour of the c
Migrating birds perform extreme endurance exercise when fly-ing. This shifts the balance between the production of reactive oxygen species and the antioxidant defense system toward the former, potentially generating oxidative damages. In between migratory flights, birds make stopovers, where besides accumulat-ing fuel (mainly fats), they are assumed to rest and recover from the strenuous flight. W
Context: The capacity of a landscape to maintain multifunctionality through ongoing pressures relates to its sustainability and is affected by land use policy and environmental changes. In coastal zones, limited empirical evidence exists regarding the impact of macro-level policy changes on local landscapes and their resulting temporal and spatial responses. Objectives: This paper investigates the
We propose a pebble-driven core accretion scenario to explain the formation of giant planets around the late-M dwarfs of M∗=0.1-0.2 M⊙. In order to explore the optimal disk conditions for giant planet, we performed N-body simulations to investigate the growth and dynamical evolution of both single and multiple protoplanets in the disks with both inner viscously heated and outer stellar irradiated
BACKGROUND: Traumatic brain injury (TBI) constitutes a global epidemic. Overall outcome is poor, with mortality ranging from 10 to 70% and significant long-term morbidity. Several experimental reports have claimed effect on traumatic edema, but no clinical trials have shown effect on edema or outcome. Antisecretory factor, an endogenous protein, is commercially available as Salovum®, which is clas
GERMAN SUMMARY: Gegenstand dieser Arbeit sind die verkürzten Formen (Kontraktionen) der englischen Modalausdrücke (‘semi-modals’) 'BE going to', 'HAVE got to' und 'want to'. Die Kontraktionen sind in der gesprochenen Sprache häufig und zeigen sich in den Schreibweisen 'gonna', 'gotta' und 'wanna'. Sie werden im Nordamerikanischen Englisch untersucht. Den Hintergrund der Arbeit bildet die GrammThe current restructuring of the English modal system has long been noted as an ongoing language change process. Semi-modal constructions such as 'BE going to' and 'HAVE got to' are textbook cases of grammaticalization. As grammaticalization comes with a rise in frequency, these semi-modals are also typical examples of the ‘reducing effect’ of frequency, which leads to the contracted forms 'gonna'
