Fire-Induced Radiological Integrated Assessment : Fire properties of selected materials and products

Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.

Heat transfer enhancement with additively manufactured rough surfaces: Insights from large-eddy simulations

To study the impact of additively manufactured (AM) roughness on fluid flow and heat transfer, we performed a series of high-fidelity large-eddy simulations on turbulent heat transfer over a three-dimensional AM rough surface with varying bulk Reynolds number and average roughness height values. We considered rough surfaces created using AM techniques at Siemens based on Nickel Alloy IN939 materia

Large-Eddy Simulations of Separated Flow and Heat Transfer in a Ribbed Channel

Ribbed channel flows are encountered in numerous engineering applications to promote turbulence and enhance heat transfer in various cooling passages, e.g., in turbine blades and at combustor walls. Numerical simulations have become an increasingly useful tool for studying the behavior of fluids in rib-roughened channels to provide insights into the complex turbulence structures and flow separatio

Fire-Induced Radiological Integrated Assessment : Fire properties of selected materials and products in reduce oxygen conditions

Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.

Formation and Evolution of Protoplanetary Discs

Protoplanetary discs and the protostars they surround are formed from the gravitational collapse of molecularcloud cores. These discs consist primarily of gas, with a small but important dust component. The roughlymm-sized grains that make up the dust component are the building blocks of planets. Over a timescale of upto a few million years, the dust in protoplanetary discs is lost. Some of the du

Towards healthcare access equality : Understanding spatial accessibility to healthcare services for wheelchair users

Considering that the number of wheelchair users is on the rise at the global level due to population aging, it is crucial to secure their rights to have adequate access to healthcare services. Spatial accessibility to healthcare services has been well recognized to influence people's health. However, research on healthcare accessibility of wheelchair users is scarce. This study proposes a barrier-

Accelerating vaccine manufacturing development through model-based approaches : current advances and future opportunities

This review highlights the importance of model-based approaches in accelerating vaccine manufacturing process development. The challenges of scaling up from laboratory to commercial processes are addressed through the adoption of Process Analytical Technology frameworks and Quality by Design principles. The application of various modeling approaches beyond downstream and upstream processes in vacc

Gut microbiota composition is altered in postural orthostatic tachycardia syndrome and post-acute COVID-19 syndrome

Postural Orthostatic Tachycardia Syndrome (POTS) reflects an autonomic dysfunction, which can occur as a complication to COVID-19. Our aim was to examine gastrointestinal symptoms and gut microbiota composition in patients with POTS and post-acute COVID-19 syndrome (PACS), compared with controls. POTS patients (n = 27), PACS patients (n = 32) and controls (n = 39) delivered fecal samples and compl

Large-scale photovoltaic solar farms in the Sahara affect solar power generation potential globally

Globally, solar projects are being rapidly built or planned, particularly in high solar potential regions with high energy demand. However, their energy generation potential is highly related to the weather condition. Here we use state-of-the-art Earth system model simulations to investigate how large photovoltaic solar farms in the Sahara Desert could impact the global cloud cover and solar gener

“You don't put it down to arthritis” : A qualitative study of the first symptoms recalled by individuals with knee osteoarthritis

Objective: As part of the first phase of the OARSI Early-stage Symptomatic Knee Osteoarthritis (EsSKOA) initiative, we explored the first symptoms and experiences recalled by individuals with knee osteoarthritis (OA). Design: This qualitative study, informed by qualitative description, was a secondary analysis of focus groups (n ​= ​17 groups) and one-on-one interviews (n ​= ​3) conducted in 91 in

The Covid-19 lesson from Sweden: Don't lock down

Covid-19 triggered a wave of lockdowns across the world, contributing to a severe downturn in economic activity. Governments responded by introducing expansionary fiscal and monetary measures. We compare the health and economic outcomes in Sweden, commonly viewed as an outlier relying more on recommendations and voluntary adjustments than on strict lockdowns, with those of comparable European OECDCovid-19 triggered a wave of lockdowns across the world, contributing to a severe downturn in economic activity.

Deciphering the normal-like molecular subtype of breast cancer

The normal-like molecular subtype of breast cancer has not been well characterized and is currently not included in the clinically approved PAM50 molecular subtype classification. Tumors classified as normallike display high expression of basal epithelial genes and low expression of luminal epithelial genes, but also high expression of genes expressed by non-epithelial cell types including adipocy

Perturbation and stability of PAM50 subtyping in population-based primary invasive breast cancer

PAM50 gene expression subtypes represent a cornerstone in the molecular classification of breast cancer and are included in risk prediction models to guide therapy. We aimed to illustrate the impact of included genes and biological processes on subtyping while considering a tumor’s underlying clinical subgroup defined by ER, PR, and HER2 status. To do this we used a populationrepresentative and cl

The Corded Ware Complex in Europe in Light of Current Archaeogenetic and Environmental Evidence

Corded Ware is one of the main archaeological phenomena of the third millennium before the common era (BCE), with a wide geographic spread across much of central and northeastern Europe, from Denmark, the Rhineland, and Switzerland in the west to the Baltic and Western Russia in the east, and broadly restricted to the temperate, continental zones north of the Alps, the Carpathians, and the steppe/
