This study investigated the presence of microplastics (MPs, >5 μm to <2 mm) in biofertilizers and estimated their mass input to Swedish agricultural soils. Collective samples from representative biogas facilities were analyzed using optical microscopy and optical photothermal infrared (O-PTIR) spectroscopy, with selected MPs examined by scanning electron microscopy (SEM). The highest MPs concentra
Particulate air pollution increases risk of cancer and cardiopulmonary disease, partly through oxidative stress. Traffic-related noise increases risk of cardiovascular disease and may cause oxidative stress. In this controlled random sequence study, 18 healthy subjects were exposed for 3h to diesel exhaust (DE) at 276μg/m(3) from a passenger car or filtered air, with co-exposure to traffic noise a
Integration of III-V semiconductors on Si substrates allows for the realization of high-performance, low power III-V electronics on the Si-platform. In this work, we demonstrate the implementation of single balanced down-conversion mixer circuits, fabricated using vertically aligned InAs nanowire devices on Si. A thin, highly doped InAs buffer layer has been introduced to reduce the access resista
To examine the risk of sleep problems associated with work stress (job strain, job demands, and decision authority), worries and pain and to investigate the synergistic interaction between these factors and traffic noise. Sleep problems and predictor variables were assessed in a cross-sectional public health survey with 12,093 respondents. Traffic noise levels were assessed using modelled A-weight
We have fabricated single balanced down-conversion mixer circuits using InAs nanowire MOSFETs as both active and passive devices. This is achieved by a combination of electron beam lithography and UV-lithography with a line width of 12 mu m. The circuits exhibit a low frequency voltage conversion gain of 6 dB, a -3 dB cutoff frequency of 2 GHz and a power consumption of 3.8 mW, while operating at
Abstract in UndeterminedSpatial data clearinghouses are one of the key features of a spatial data infrastructure (SDI). However, recent research indicates that few national clearinghouses function well, as the spatial data resources available cannot be satisfactorily accessed or optimally used. To improve the functionality, we propose that clearinghouses to be complemented with expert systems and
In the formulation of an active enzyme enclosed in a matrix for controlled delivery, it is a challenge to achieve a high protein load and to ensure high activity of the protein. For the first time to our knowledge, we report the use of a highly swollen lipid sponge (L3) phase for encapsulation of the large active enzyme, β-galactosidase (β-gal, 238 kDa). This enzyme has large relevance for applica
Plastics are widely used in todays society leading to an accelerating amount of plastic waste entering natural ecosystems. Over time these waste products degrade to micro- and, eventually, nanoplastic particles. Therefore, the break-down of plastics may become a critical threat to aquatic ecosystems and several short term studies have demonstrated acute toxicity of nanoplastics on aquatic organism
To understand the developmental trajectories in early lymphocyte differentiation, we identified differentially expressed surface markers on lineage-negative lymphoid progenitors (LPs). Single-cell polymerase chain reaction experiments allowed us to link surface marker expression to that of lineage-associated transcription factors (TFs) and identify GFRA2 and BST1 as markers of early B cells. Funct
Begreppet plattformar har under de senaste åren seglat upp som ett av de mest centrala begreppen i den digitala ekonomin. Digitala plattformar möjliggör mängder av nya, effektiva sätt att organisera samhället – med långtgående konsekvenser för en rad centrala samhällsfunktioner. Detta ställer en rad frågor om medbestämmande och reglering, om innovationens förutsättningar och hur en plattformsmedve
Current techniques for visualising geospatial Linked Data are limited in terms of multiple representation, which has been studied for decades by cartographers and considered as a prerequisite for deriving appropriate geovisualisation applications. In order to alleviate this issue, this paper presents a work in progress, in which the multiple representation geospatial data are released as Linked Da
The Paris Agreement requests a substantial reduction of greenhouse gas (GHG) emissions. These emissions are currently mainly estimated from bottom-up inventories and process-based models of land and ocean fluxes. Another, complementary approach is based on measurements of the atmospheric GHG concentration in combination with atmospheric inverse modelling to provide the GHG fluxes. For the latter a
Measuring the number concentration of colloidal nanoparticles (NPs) is critical for assessing reproducibility, enabling compliance with regulation, and performing risk assessments of NP-enabled products. For nanomedicines, their number concentration directly relates to their dose. However, the lack of relevant reference materials and established traceable measurement approaches make the validation
Under snart tre decennier har omfattande insatser genomförts för att få mäns våld mot kvinnor att upphöra, utan synbar effekt. Våldet tenderar snarare att öka. Varför tycks mäns våld mot kvinnor vara ett olösligt samhällsproblem? I denna rapport undersöker vi hur mäns våld mot kvinnor har hanterats i svensk politik de senaste 25 åren. Med utgångspunkt i offentligt tryck granskar vi den politiska r
Hematopoietic stem cells (HSCs) are rare cells on top of the differentiation hierarchy of hematopoiesis. HSCs are unique in their combined capacity to differentiate into all mature blood lineages and self-renew to maintain the HSC pool. Based on classical models of hematopoiesis in mouse, the self-renewal potential of HSCs is gradually and step-wise lost during the transition from long term (LT)-H
Aging negatively affects hematopoiesis, with consequences for immunity and acquired blood cell disorders. Although impairments in hematopoietic stem cell (HSC) function contribute to this, the in vivo dynamics of such changes remain obscure. Here, we integrate extensive longitudinal functional assessments of HSC-specific lineage tracing with single-cell transcriptome and epitope profiling. In cont
BACKGROUND: Electronic health records (EHRs) are generated at an ever-increasing rate. EHR trajectories, the temporal aspect of health records, facilitate predicting patients' future health-related risks. It enables healthcare systems to increase the quality of care through early identification and primary prevention. Deep learning techniques have shown great capacity for analyzing complex data an
Knee joint functional deficits are common after anterior cruciate ligament (ACL) injury, but different assessment methods of joint function seem to provide contradicting information complicating recovery monitoring. We previously reported improved perceived knee function and functional performance (forward lunge ground contact time) in patients with an ACL injury from pre to 10 months post ACL rec
