Temporal Variation of Road Dust Load and Its Size Distribution—a Comparative Study of a Porous and a Dense Pavement

Resuspension of road dust contributes to air quality issues with resulting health impacts. Limited studies imply that porous pavements can initially mitigate PM10 emissions by acting as a dust trap, but the abrasion wear generates road dust and thus accelerates the clogging processes. In addition, knowledge regarding the impact of pavement types on road dust load dynamics is limited. Road traffic

Wet Dust Sampler : A Sampling Method for Road Dust Quantification and Analyses

In northern countries, the climate, and consequently the use of studded tyres and winter traction sanding, causes accumulation of road dust over winter and spring, resulting in high PM10 concentrations during springtime dusting events. To quantify the dust at the road surface, a method—the wet dust sampler (WDS)—was developed allowing repeatable sampling also under wet and snowy conditions. The pr

Porous pavement for reduced tyre/road noise and improved air quality : Initial results from a case study

One possible solution to reduce noise resulting from tyre-pavement interaction is to use a porous pavement surface. A porous surface will reduce noise by decreasing air pressure gradients in the tyre-pavement contact as well as by decreasing the acoustical impedance of the road surface and reducing the horn effect. While reducing noise, other functional aspects of a pavement such as abrasion wear

Road dust load dynamics and influencing factors for six winter seasons in Stockholm, Sweden

Traffic related non-exhaust particulate sources and road dust are an increasingly important source for PM10 air pollution as exhaust sources are decreasing due to regulations. In the Nordic countries, the road dust problem is enhanced by use of studded tyres, causing increased road wear and winter road maintenance including gritting. Efforts to reduce road dust emissions requires knowledge on temp

Labour-intensive Garment-based Industrialization with Social Sustainability? The Case of Mauritius

We address the social sustainability dimension of labor-intensive industrialization (LII) and manufacturing activities and apply it to the analysis of Mauritius, a regional forerunner in textile and garment production. While the country is commonly seen as an African success story, we do not evaluate its trajectory against traditional economic theory on achieving sustained growth. Instead, we anal

Brain perfusion and blood-brain barrier permeability in systemic lupus erythematosus patients : Associations with disease activity, cognitive dysfunction, fatigue and pain

High disease activity, cognitive dysfunction (CD), fatigue and pain negatively affect the quality of life in patients with systemic lupus erythematosus (SLE). However, the impact on brain perfusion and blood-brain barrier (BBB) permeability remains incompletely understood. Therefore, we utilized 3 T dynamic susceptibility contrast magnetic resonance imaging to investigate these factors in a cohort

Discharging thermal management of a type IV storage tank of hydrogen fuel cell electric vehicles with a novel solution procedure

The promotion of hydrogen fuel cell electric vehicles (HFCEVs) is of great significance for reducing carbon emissions and strengthening environmental protection effects. However, the temperature drop occurred during discharging, becomes a key safety hazard for the reliable operation of HFCEVs. In this study, a type IV hydrogen storage tank with a pressure of 70 MPa is adopted to research the therm

Degrees of Freedom for Radiating Systems

Electromagnetic degrees of freedom are instrumental in antenna design, wireless communications, imaging, and scattering. A large number of degrees of freedom enhance control in antenna design, influencing radiation patterns and directivity, while in communication systems, it links to spatial channels for increased data rates, reliability, and resolution in imaging. The correlation between computed

Grapefruit-derived nootkatone potentiates GABAergic signaling and acts as a dual-action mosquito repellent and insecticide

Humanity has long battled mosquitoes and the diseases they transmit—a struggle intensified by climate change and globalization, which have expanded mosquito ranges and the spread of associated diseases.1 Additionally, widespread insecticide resistance has reduced the efficacy of current control methods, necessitating new solutions.2,3 Nootkatone, a natural compound found in grapefruit, shows promi

Study of Air Quality over Delhi during COVID-19 Lockdown Based on Remote Sensing Observations

Increasing concentrations of toxic pollutants and particulate matter are a major concern related to human health. The present work is structured into two phases; the first is aimed at understanding the O3–NOX–VOC sensitivity over Delhi during the lockdown period; the second phase examines the influence of dust-induced aerosol particles on air pollution during the lockdown period using satellite-de

Universal Waterfall Feature in Cuprate Superconductors : Evidence of a Momentum-Driven Crossover

We study two related universal anomalies of the spectral function of cuprates, so-called waterfall and high-energy kink features, by a combined cellular dynamical mean-field theory and angle-resolved photoemission study for the oxychloride NaxCa2-xCuO2Cl2 (Na-CCOC). Tracing their origin back to an interplay of spin-polaron and local-correlation effects both in undoped and hole-doped (Na-)CCOC, we

Completion of registration of risk factor variables during telephone vs on-site follow-up after myocardial infarction : a nationwide observational study in 101 199 patients from contemporary clinical practice in Sweden

Objectives The objective of this study was to assess the completeness of registration of secondary preventive variables comparing on-site visits with telephone consultations during follow-up after myocardial infarction. Design This was an observational study based on the Swedish quality registry SWEDEHEART. Setting and outcome measures We analysed the proportion of missing values for major seconda

Molecular analysis of acute pyelonephritis—excessive innate and attenuated adaptive immunity

This study investigated the molecular basis of disease severity in acute pyelonephritis (APN), a common and potentially life-threatening bacterial infection. Two cohorts of infants with febrile urinary tract infection were included. Renal involvement was defined by DMSA scans and molecular disease determinants by gene expression analysis and proteomic screens, at diagnosis and after 6 mo. Innate i

Testing the predictions of reinforcement : long-term empirical data from a damselfly mottled hybrid zone

Theoretical work suggests that reinforcement can cause the strengthening of prezygotic isolation in sympatry by mitigating the costs of maladaptive hybridization. However, only a handful of studies have simultaneously tested multiple predictions of this theory in natural populations. We investigated reinforcement in a mottled hybrid zone between the damselflies Ischnura elegans and Ischnura graell

Analysis of the impact of the EU Taxonomy on investments in District Heating

If policy meets its intended goals or not is important in the context of energy transition. We explore if a policy, the EU Taxonomy, designed to foster green investments, meets its intent. We built an overall understanding about the EU Taxonomy by reviewing literature and EU Taxonomy documents. Additionally, we test constraints from the EU Taxonomy on CO2 emissions and on new investments in fossil

Prevalence of Temporomandibular Disorder Symptoms After Whiplash Trauma—A Systematic Review and Meta-Analysis

Background and Objectives: Temporomandibular disorders (TMDs) is an umbrella term for pain and dysfunction involving jaw muscles and/or the temporomandibular joint, with whiplash trauma suggested to be one risk factor. The aim was to evaluate prevalence and relative risk of TMDs in the acute and chronic stages after whiplash trauma. Databases and Data Treatment: This review was registered in Prosp

Leadership Communication as Materiality, Embodiment, and Aesthetics

The leadership literature has been faulted for framing leaders (and followers) as rational and disembodied information processers.
