Conventional dialyzer membranes typically comprise of unevenly distributed polydisperse, tortuous, rough pores, embedded in relatively thick ≈20–50 µm polymer layers wherein separation occurs via size exclusion as well as differences in diffusivity of the permeating species. However, transport in such polymeric pores is increasingly hindered as the molecule size approaches the pore dimension, resu

This document compares two approaches to finding resonance peaks from asingle sensor: 1) averaging multiple measurements of the transfer function orfrequency-domain scattering matrix, versus 2) using the iterative time-reversalprocess, which involves iteratively re-transmitting a time-reversed version ofthe scattered field at the previous iterations. The averaging method has theadvantage of handli

Based on the author Cathy Urquhart's own wealth of experience this timely, engaging book helps first-time researchers to discover the excitement of grounded theory method. Fresh, innovative and clear, this book traces the history and development of grounded theory method, and examines how the method is evolving for new contexts today. It sets out the principles involved in using grounded theory me

Sedan några årtionden tillbaka har hundratals gator, torg och byggnader i olika världsdelar namngivits efter Raoul Wallenberg. Under samma period har han blivit motiv på frimärken och tonsättare har skrivit musikaler och operor om hans levnadsöde. Dessutom har hans gärning i Budapest 1944–1945, då han gjorde sitt yttersta för att rädda så många som möjligt av judarna i Ungern undan förintelsen, fi

Recension av Henrik Berggren, Landet utanför 1–3: Sverige och kriget 1939–1940 (2018); Sverige och kriget 1940–1942 (2021); Sverige och kriget 1943–1945 (2023)

Control engineering is a well-established discipline with a long and prominent his-tory1. It is diverse in its applications but has a strong unifying core to it: the notion ofdynamic systems and control theory. Many engineers will have encountered it as partof their education, as control engineering courses are taught to electrical, mechanical,chemical, aerospace, and industrial engineers. Quite o

We conducted a multi-ancestry genome-wide association study of prostate-specific antigen (PSA) levels in 296,754 men (211,342 European ancestry; 58,236 African ancestry; 23,546 Hispanic/Latino; 3,630 Asian ancestry; 96.5% of participants were from the Million Veteran Program). We identified 318 independent genome-wide significant (p≤5e-8) variants, 184 of which were novel. Most demonstrated eviden

Manual dismantling, shredding, and mechanical grinding of waste from electrical and electronic equipment (WEEE) at recycling facilities inevitably lead to the accidental formation and release of both coarse and fine particle aerosols, primarily into the ambient air. Since diffuse emissions to air of such WEEE particles are not regulated, their dispersion from the recycling plants into the adjacent

With population aging, more adults across Europe face competing demands of working for pay and caring for elderly family members. Associated tradeoffs are expected to be negative,gendered and vary across contexts with different levels of gender equality, public support for eldercare, and work-family balance. Using SHARE data from 2004 to 2020, we investigated how unpaid caregiving to independently

"Jag vill inte ha något arvode för mina tjänster", sa Fader Gunnar. "Skänk en slant till min kyrka i stället!" Men när en taxeringsintendent upptäcker arrangemanget blir prästen anklagad för att vara skattesmitare, och hamnar i en rättegång som leder ända till Högsta förvaltningsdomstolen.

The increasing interest in seaweed as a food resource in Western societies raises concerns about associated potentially toxic elements (PTEs), including arsenic, cadmium, mercury, lead, and iodine. Hence, this study examined variation in PTEs by including samples of four different species (Ulva lactuca, Palmaria palmata, Alaria esculenta, and Saccharina latissima) from Ireland, as well as of a sin

User involvement in research is advocated as an avenue for efficient societal developments. In this article, we identify potentials, problems, and challenges related to research on aging and health, and identify and illustrate research priorities using an evolving research program as an example. Involving user representatives in the development phase, the UserAge program engages researchers at fou

Sherry Turkle in her groundbreaking book 'Alone Together' suggests that the Internet gives an illusion of togetherness while contributing to isolation. How might this play out in social movements on the Internet? Can social media bring people together? This research in progress explores the role of social media as a way to facilitate collective political action. It discusses the preliminary findin

This report takes stock of the current climate finance landscape in India, along with the estimated financing requirements, enabling conditions and macro policy instruments to achieve national 1.5oC and 2oC goals. Climate change will negatively affect India’s economy leading to annual Gross Domestic Product (GDP) loss of 3 per cent to 10 per cent by 2100 (Kompas et al., 2018; RBI, 2023). In a busi

Cosmogenic radionuclides (e.g., 10Be) from ice cores are a powerful tool for solar reconstructions back in time. However, superimposed on the solar signal, other factors like weather/climate and volcanic influences on 10Be can complicate the interpretation of 10Be data. A comprehensive study of 10Be records over the recent period, when atmospheric 10Be production and meteorological conditions are

The three leading modes of the North Atlantic atmospheric circulation explain about 70% of the winter climate variability. Although climate models generally can capture these modes, biases may induce large uncertainties in regional climate predictions. Here, we evaluate the leading winter modes simulated by CMIP5-PMIP3 and CMIP6-PMIP4 models from the last millennium to future scenarios in comparis

Aromatic side chains (phenylalanine and tyrosine) of a protein flip by 180° around the Cβ-Cγ axis (χ2 dihedral of the side chain), producing two symmetry-equivalent states. The study of ring flip dynamics with nuclear magnetic resonance (NMR) experiments helps to understand local conformational fluctuations. Ring flips are categorized as slow (milliseconds and onward) or fast (nanoseconds to near

Background: For many children, public playgrounds represent environments that are playful and important in developing good health. Without efforts to facilitate climate change adaptation of outdoor playgrounds there may be a negative impact on children's health and well-being.Aim: With a special focus on play value, to explore the reasoning and described strategies among professionals responsible
