Delignification is a critical step of the wood fractionation process in a biorefinery. It directly influences the purity of lignin and aids in breaking bonds within lignin and lignin–carbohydrate complexes surrounding cellulose. The recalcitrant nature of lignocellulose poses challenges in fractionating the material, notably during delignification. Recent progress in understanding lignin’s phy
In North and East Syria—also known as Rojava—the convergence of war, politics, and environmental challenges presents a complex and pressing reality. This blog is dedicated to exploring these interlinked issues, highlighting how conflict and ecological degradation are deeply connected, and how these dynamics affect communities in varied and unequal ways.
Årligen upptäcks nya kärlväxter i Sverige. Det kan vara arter som etablerar sig i Sverige i klimatförändringarnas spår, som följer med internationella transporter, och inte minst trädgårdsrymlingar. Det finns flera skäl till att dokumentera dessa, inte minst för att förebygga spridning av invasiva arter. Biologiska museet i Lund tar emot belägg och listar här de arter som var nya för Sverige 2023.
I slutet av januari i år hölls en konferens om granskning av kärlväxtuppgifter i samband med produktionen av en svensk kärlväxtatlas. Svenska Botaniska Föreningen organiserade konferensen i samarbete med Naturhistoriska Riksmuseet. Mötet hölls i Riksmuseets lokaler i Stockholm med cirka 35 deltagare.
Följ med på inventeringsläger i sommar. Tre läger arrangeras på platser i Dalarna, Jämtland, Ångermanland och Lappland där fler växtuppgifter behövs.
The two surviving Betony localities in Denmark are located in southwestern Lolland. The future of both populations has been secured at nine reserve localities established in 2017–2024. Plants from Bjerremark (Tågerup parish) can be found at five localities: Guldborgsund Zoo and Botanical Garden, Medical-historical Museum in Næstved,the Barock Garden at Søholt castle, Røgbøllemarken in Søholt Stors
A drop of systemic blood pressure (BP) occurring shortly after individuals move from supine or seated position to upright posture with subsequent prompt spontaneous resolution is a common physiological occurrence in humans. If the induced hypotension is severe, lightheadedness or postural instability leading to falls and injury may occur. By consensus, a transient systolic BP drop >40 mmHg within
The 2022 EU Directive on Adequate Minimum Wages aims to ensure adequate minimum wages and strengthen collective bargaining in order to reduce in-work poverty and wage inequality. The national transposition and implementation of the Minimum Wage Directive will be heavily shaped by the existing collective bargaining and minimum wage regimes in the 27 EU Member States. To monitor and understand the p
The article contributes to the research of platformisation of everyday life and children’s television use by exploring how 0-3-year-olds’ television viewing on screen media is embedded in daily social practices of families in Sweden. The article examines the research questions: 1) What social practices are organised around young children’s television viewing on screen media? 2) How can these telev
The impact of the Russian war against Ukraine should have far-reaching repercussions on the teaching of International Relations (IR) and European Union (EU) studies. In this article, it is argued that Ukrainian resistance to the invasion must be part of an important shift in thinking about IR and the EU within holistic planetary politics. First, the terminologies and technologies of teaching IR an
Proton exchange membrane fuel cells are a promising green energy conversion technology for clean and sustainable power generation. However, effective water management remains a critical challenge. Water produced by electrochemical reactions can accumulate within porous electrodes and flow channels, leading to flooding that impedes the reverse transport of reactant gases to the reaction zone, there
This article examines the media construction of Duke Johan of Östergötland (1589–1618), a Swedish prince, through the lens of his recorded gift giving practices. It posits that gifts should be conceptualized as media, shaping the construction of Duke Johan as a ruler and virtuous prince, both in the early seventeenth century and for posterity. By analyzing the remediation of Duke Johan’s gift givi
Om Konstantinopels fall 1453.
Between 1850 and 1930, millions of Europeans emigrated to the United States, attracted by opportunities for a better life. We study the role of migrant networks in fostering emigration, using individual-level Swedish full-count census data for men and women, linked to emigration records. Our findings show that having previously migrating siblings was an important determinant of emigration, particu
We propose a single-shot Carrier-Envelope Phase measurement scheme, based on evaluating f-2f fringes by means of optical Fourier transform. The method is suitable for measuring at high-repetition rate (> 200kHz) and low pulse energy.
Acute mesenteric venous thrombosis accounts for up to 20% of all patients with acute mesenteric ischemia in high-income countries and is a very difficult disease to diagnose on clinical grounds. However, owing to the increased availability and evolution of computed tomography in high-income countries, early diagnosis prior to the development of peritonitis is often possible. First-line therapy is
Background: Recurrent coarctation of the aorta (re-CoA) is a well-known although not fully understood complication after surgical repair, typically occurring in 10%–20% of cases within months after discharge. Objectives: To (1) characterize geometry of the aortic arch and blood flow from pre-discharge magnetic resonance imaging (MRI) in neonates after CoA repair; and (2) compare these measures bet
This paper investigates online gender-based violence (OGBV) in China using the perspectives of queer feminism and cyberfeminism. As a case study, it examines the cyberviolence against the “Pink Hair Girl” on Xiaohongshu (a popular Chinese social media platform) and the subsequent resistance by women. The study focuses on the following questions: How does the symbolic use of pink hair represent que
