Airborne SARS-CoV-2 is considered to play a major role in covid-19 transmission, and several studies have reported its presence in hospital environments, including corridors, patient rooms, cohort rooms and ICUs (Dinoi et al., 2022). The risk of airborne virus have been associated with a number of factors, such as low ventilation, high patient viral load and in some cases, certain medical procedur

Airborne SARS CoV 2 is considered to play a major role in covid 19 transmission, and has been found in several hospital environments. There is a need to investigate the presence of airborne SARS CoV 2 in other hospital areas than traditional infectious disease wards. The results from the present study can contribute to a better understanding of the risk of covid 19 transmission by aerosols at deli

We demonstrate that finite impulse response (FIR) models can be applied to analyze the time evolution of an epidemic with its impact on deaths and healthcare strain. Using time series data for COVID-19-related cases, ICU admissions and deaths from Sweden, the FIR model gives a consistent epidemiological trajectory for a simple delta filter function. This results in a consistent scaling between the

Perinatal exposure to starvation is a risk factor for development of severe retinopathy in adult patients with diabetes. However, the underlying mechanisms are not completely understood. In the present study, we shed light on molecular consequences of exposure to short-time glucose starvation on the transcriptome profile of mouse embryonic retinal cells. We found a profound downregulation of genes

Are you worried about the climate and biodiversity crises and related events like heavy rainfalls and floods, high carbon emissions, sudden heat waves, or loss of species? Are you already doing something to help solve these problems? To reduce flood risks, we can give rivers more space by reconnecting floodplains. To store carbon and help to slow down climate change, we can protect and establish w

Ambient airborne particles with an aerodynamic diameter of <2.5 µm (PM2.5), which contain particles from combustion processes, are linked to increased risks for cardiovascular and respiratory diseases. In this experimental study, the short-term and long-term physiologic consequences of PM2.5 inhalation were investigated with the focus on inflammatory parameters and vascular tonus. PM2.5 collected

Our aim was to explore possible relationships between serum levels of biomarkers in patients with hand-arm vibration injury in relation to the severity of the vascular, i.e., Raynaud’s phenomenon (RP), and neurosensory manifestations, the current exposure level, and the duration of exposure. This study was of case series design and involved 92 patients diagnosed with hand-arm vibration injury. Jon

This article investigates the dependence on standard contracts in Swedish construction law, particularly AB 04 and ABT 06, due to a lack of specialized laws. Comparing them to similar contracts from other Nordic countries demonstrates the value of cross-border legal understanding. A 2018 Swedish Supreme Court judgment highlights this technique, implying that comparative analysis might improve leg

The disruption of microtubule dynamics serves as a pivotal strategy for eliminating tumor cells, despite its accompanying toxicities affecting non-tumor cells. This study investigates the potential of selectively targeting γ-tubulin1 (TUBG1) as a therapeutic strategy in cancer treatment. By elucidating the TUBG1-E2F1-retinoblastoma protein (RB1) network, we introduce a novel compound, 4-(6-((3-Met

Ti (C, N) based cermet materials are predominantly used in continuous finishing applications of metal cutting due to their high hardness, excellent resistance to oxidation and high chemical stability. However, their application in interrupted cutting like milling are limited due to their brittle-like failure due to low fracture toughness. In this work, alternative binder systems such as Co-Ni and

Tool wear is one of the dominant factors that impacts the surface integrity of machined materials. Understanding the impact of tool wear on surface integrity is crucial in micromilling, due to the size of the features being machined and the cutting tools. Therefore, this work aims to analyse the impact of tool wear on surface integrity during the micromilling of Ti6Al4V. In this context, microslot

Lean, premixed, swirl-stabilized flames are widely used in modern Dry Low Emissions gas turbine combustors; however, the turbulent combustion process under those conditions is known to be extremely sensitive and prone to instabilities. Numerical simulations can be a valuable tool in predicting the effects of alternative fuels; however, the sensitivity of the results to different models ought to be

The breakdown of relations between China and the US has prompted Beijing to shore up existing friendships, and seek new ones.

Polycrystalline cubic boron nitride (PcBN) is renowned for its exceptional hardness and thermal stability, making it ideal for extreme machining conditions. Coatings on PcBN tools further enhance performance by extending tool life and improving cutting efficiency. While uncoated PcBN tools already excel in harsh environments, coatings primarily boost durability. Although extensively studied in tur

The combustion of conventional Jet A, alongside two alternative jet fuels, C1 and C5, is simulated with Large Eddy Simulations (LES) in a generic single-cup spray combustor during idle and cruise conditions. The spray is modeled using Lagrangian particle tracking and the combustion chemistry of each fuel is modeled by skeletal reaction mechanisms. The volatility and atomizability of each fuel dire

This chapter argues that how the neoliberal notion of ‘attractive space’ emerged as a planning paradigm in the renewal of the Western Harbor district of Malmö, Sweden, unleashed powerful contradictions. The chapter shows that although the urban design of the area was intended to attract affluent residents from the suburbs to the city, people from less affluent and more ethnically diverse areas of

Non-round cell sarcomas may occur in children or young adolescents. We present some examples of the most common entities: epithelioid sarcoma, osteosarcoma; malignant peripheral nerve sheath tumor (MPNST), congenital infantile fibrosarcoma, and synovial sarcoma.
