The tremendous increases in production of plastic materials has led to an accumulation of plastic pollution worldwide. Many studies have addressed the physical effects of large-sized plastics on organisms, whereas few have focused on plastic nanoparticles, despite their distinct chemical, physical and mechanical properties. Hence our understanding of their effects on ecosystem function, behaviour
The development of good writing skills is fundamental not only to publish scientific results, but also to have a deeper understanding of complex subjects. However reports from the Swedish Higher Education Authority from 2012-2015 suggest that engineering students at Lund University have unsatisfactory academic writing skills. Our paper investigates how students of the Faculty of Engineering at Lun
We analyse the effects of soil type on mortality of children aged 2-15 living in five rural parishes in Sweden between 1850 and 1914. We use micro-level longitudinal demographic data combined with micro-level longitudinal geographic data. Here, the individuals in the parishes are linked to the property units they lived in. We find that, compared to those living in property units covered by 80-100%
BackgroundChild mortality differed greatly within rural regions in Europe before and during the mortality decline. Not much is known about the role of nutrition in such geographic differences, and about the factors affecting the nutritional level and hence the resistance to diseases.ObjectiveFocusing on nutrition, we analyse the effects of soil type, used as an indicator of the farm-level agricult

An active single balanced down-conversion mixer is implemented using InAs nanowire metal oxide semiconductor field effect transistors (MOSFETs) as both active devices and passive resistive loads. Circuits with 6 dB low-frequency voltage gain and a 3 dB bandwidth of 2 GHz are measured for a DC power consumption of 3.8 mW from a 1.5 V supply. The circuits are fabricated using contacts made with 12 μ
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
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
Heart failure (HF) is the end-stage of all heart disease and arguably constitutes the greatest unmet therapeutic need in cardiovascular medicine today. Classic epidemiological studies have established clinical risk factors for HF, but the cause remains poorly understood in many cases. Biochemical analyses of small case-control series and animal models have described a plethora of molecular charact
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
Chronic obstructive pulmonary disease (COPD) is a progressive condition characterized by airway remodeling, including emphysema and fibrosis. Proteoglycans and their glycosaminoglycan (GAG) chains are key components of the extracellular matrix and may be altered as the disease advances. This study analyzed lung tissue from COPD patients (GOLD stages II-III and IV), non-COPD smokers, and non-smoker
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
Background: Exposure and Response Prevention (ERP) is a form of behavioural therapy for tics; however, its effectiveness remains uncertain. We aimed to evaluate the effectiveness of internet-delivered, therapist-supported, and parent-assisted ERP for treatment of tics in children and young people with Tourette syndrome or chronic tic disorder. Methods: This multicentre, parallel group, single-blin
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
Background: Lung injury in COVID-19 is characterized by neutrophil invasion and the release of neutrophil extracellular traps (NETs). An aberrant NET formation may induce local inflammation and increase sputum viscosity. Inhalation of DNase I (dornase alfa) is a treatment option that degrades NETs in the airways. Previous case series have indicated positive clinical effects of inhaled dornase alfa
Plasma concentrations of many cardiovascular and inflammatory proteins are altered after ST-elevation myocardial infarction (STEMI) and may provide prognostic information. We conducted a large-scale proteomic analysis in patients with STEMI, correlating protein levels to infarct size and left ventricular ejection fraction (LVEF) determined with cardiac magnetic resonance imaging. We analysed 131 c
Syftet med uppsatsen är att studera och analysera hur en räntehöjning respektive -sänkning påverkar aktiekursen samt om det föreligger någon skillnad mellan olika branscher och soliditetsnivåer. Vi har genomfört en kvantitativ studie, en händelsestudie, av totalt 60 svenska företag fördelade på sex olika branscher, alla noterade på Stockholmsbörsen. Vi har beräknat den onormala avkastningen för al
