Plant morphogenesis is governed by the mechanics of the cell wall—a stiff and thin polymeric box that encloses the cells. The cell wall is a highly dynamic composite material. New cell walls are added during cell division. As the cells continue to grow, the properties of cell walls are modulated to undergo significant changes in shape and size without breakage. Spatial and temporal variations in c

ABC-stacked multilayer graphene (ABC-MLG) exhibits topological surface flat bands with a divergent density of states, leading to many-body instabilities at charge neutrality. Here, we explore electronic ordering within a mean-field approach with full generic treatment of all spin-isotropic, two-site charge density and spin interactions up to next-nearest-neighbor (NNN) sites. We find that surface

Importance: Despite some promising preclinical and clinical data, it remains uncertain whether remote ischemic conditioning (RIC) with transient cycles of limb ischemia and reperfusion is an effective treatment for acute stroke. Objective: To evaluate the effect of RIC when initiated in the prehospital setting and continued in the hospital on functional outcome in patients with acute stroke. Desig

Whole-body glucose homeostasis is coordinated through secretion of glucagon and insulin from pancreatic islets. When glucose is low, glucagon is released from a-cells to stimulate hepatic glucose production. However, the mechanisms that regulate glucagon secretion from pancreatic a-cells remain unclear. Here we show that in a-cells, the interaction between fatty acid oxidation and glucose metaboli

This article examines two of the most canonical plays in all of Scandinavian and European modern drama – Henrik Ibsen’s Hedda Gabler (1890) and August Strindberg’s A Dream Play (1902) – through the prism of the history of knowledge. The primary claim of the article is that these two plays are paradigmatic literary representations and critiques of one of the main historical processes pertaining to

The aim of this study is to explore pre-service teachers’ procedural and conceptual understanding of pupils’ understanding of mean value, before and after an intervention. Participants are 66 pre-service teachers, and two teacher educators. The data consists of five video-recorded lessons and pre-service teachers’ pre- and post-test discussions. Based on variation theory, the analysis aimed to ide

Kort introduktion till om hur svenska kvinnor vann tillträde till högre studier genom ett riksdagsbeslut 1873 samt presentation av de sätt på vilka Lunds universitet högtidlighållit detta 150-årsjubileum.

Introduction: The analysis of urinary catecholamine metabolites is a cornerstone of neuroblastoma diagnostics. Currently, there is no consensus regarding the sampling method, and variable combinations of catecholamine metabolites are being used. We investigated if spot urine samples can be reliably used for analysis of a panel of catecholamine metabolites for the diagnosis of neuroblastoma. Method

Cat purring, the unusual, pulsed vibration that epitomizes comfort, enjoys a special status in the world of vocal communication research. Indeed, it has long been flagged as a rare exception to the dominant theory of voice production in mammals. A new study presents histological and biomechanical evidence that purring can occur passively, without needing muscle vibration in the larynx controlled b

PURPOSE: To investigate the role of adiposity in the associations between ultra-processed food (UPF) consumption and head and neck cancer (HNC) and oesophageal adenocarcinoma (OAC) in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.METHODS: Our study included 450,111 EPIC participants. We used Cox regressions to investigate the associations between the consumption of

Sustainable agriculture requires balancing crop yields with the effects of pesticides on non-target organisms, such as bees and other crop pollinators. Field studies demonstrated that agricultural use of neonicotinoid insecticides can negatively affect wild bee species 1,2, leading to restrictions on these compounds 3. However, besides neonicotinoids, field-based evidence of the effects of landsca

This chapter looks at three different cases, which extend from literature to protest, to examine the multimodality of translation and translanguaging in intercultural communication. The cases include excerpts from the novel On Earth We Are Briefly Gorgeous, the graphic novel Persepolis and practices of lip-sewing among refugees, as documented in online media. They represent different communicative

In the face of the triple planetary crisis, which includes climate change, biodiversity loss and environmental degradation, there is growing recognition that the environment needs to be re-evaluated and better protected. Recent developments, such as a values assessment by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES),1 the concept of biocultural right

This incisive Research Handbook addresses the growing recognition within the international law community that natural resource governance and environmental protection are crucial aspects of peace processes, both as a security imperative and as an opportunity for peacebuilding. Examining the impact of international normative and institutional frameworks on environmental peacebuilding, this Research

En artikel som utforskar Lunds domkyrkas roll i skandinavismen utifrån Tegnérs lagerkransande av Oehlenschläger vid magisterpromotionen 1829, de skandinaviska studentmötena 1845 och 1862, samt det andra skandinaviska kyrkomötet 1859.
