Introduction: We have previously adapted a clinical linear accelerator (Elekta Precise, Elekta AB) for ultra-high dose rate (UHDR) electron delivery. To enhance reliability in future clinical FLASH radiotherapy trials, the aim of this study was to introduce and evaluate an upgraded beam control system and beam tuning process for safe and precise UHDR delivery. Materials and Methods: The beam contr
Knowledge resistance can be defined as the state where we are “almost immune to evidence, or experiences of others” (Klintman 2022:323). The phenomenon, often described using related terms, remains highly relevant to understanding the challenges and opportunities of agreeing on the existence, severity, causes and solutions to environmental problems. The concept of knowledge resistance is related t
The structure of the η′ phase, one of the most important age-hardening precipitates in commercial Al-Zn-Mg alloys, has been studied at the atomic level by means of high-resolution electron microscopy (HREM). A structural model of the η′ phase has been constructed on the basis of the structural characteristics in the observed images and the structure of the η-MgZn2 phase. Image simulation of this m
Aerobic granular sludge (AGS) plants have gained growing interest and application due to their low energy demand, small footprint, and low operational costs. However, the fulfilment of strict discharge limits for nitrogen and phosphorus, vast seasonal temperature variations, and large peaks in influent flows may pose challenges to the implementation of AGS. Moreover, the knowledge about microbial
BACKGROUND: As mild cognitive impairment (MCI) is typically used to identify prodromal stages of dementia, it is essential to identify MCI criteria with high diagnostic stability and prediction of dementia. Moreover, further investigation into pinpointing key factors for reversion is required to foresee future prognosis of MCI patients accurately.OBJECTIVE: To explore disparities in diagnostic sta
The subgenus Sarcophaga Meigen, 1824 (s. str.) currently comprises over 30 species distributed in the West Palearctic Region, the identification of which is normally based on characters of the male terminalia. Females of the three closely-related species Sarcophaga (Sarcophaga) carnaria (Linnaeus, 1758), S. (S.) subvicina Rohdendorf, 1937 and S. (S.) variegata (Scopoli, 1763), which are especially
The jet angularities are a class of jet substructure observables which characterize the angular and momentum distribution of particles within jets. These observables are sensitive to momentum scales ranging from perturbative hard scatterings to nonperturbative fragmentation into final-state hadrons. We report measurements of several groomed and ungroomed jet angularities in pp collisions at s = 5.
Our current view of the evolutionary history, coding and adaptive capacities of Apicomplexa, protozoan parasites of a wide range of metazoan, is currently strongly biased toward species infecting humans, as data on early diverging apicomplexan lineages infecting invertebrates is extremely limited. Here, we characterized the genome of the marine eugregarine Porospora gigantea, intestinal parasite o
This study aimed to investigate subjective health and its associations with perceived body image (body appearance and body functioning), physical activity, perceived wellbeing in school, perceived family financial situation, and body mass index among 13- to 15-year-old boys and girls. The study was a cross-sectional study performed in four municipalities in Southern Sweden. Data were obtained from
Finished Goods Distribution Network (FGDN) design is an important aspect of Supply Chain Management (SCM), and companies are constantly working towards balancing cost, service level and product quality in the design. At the same time, sustainability has gained an increased focus by stakeholders which has led to both challenges and opportunities in the logistics industry. The FGDN optimization is e
α-CGRP 8-37 is a peptide fragment of calcitonin gene-related peptide and is commonly used as a CGRP antagonist in pharmacological research. CGRP signaling has been discussed in relation to neuroimmune mechanisms in psoriasis, but a practical development of α-CGRP 8-37 requires analytical methods and formulation strategies that can handle peptide instability, adsorption, and matrix effects. The aim
This study aimed to find and explore potential relations between the consumption of news on social media and psychological distress in young adults through the term news-related posts on social media. This quantitative survey study utilized a sample consisting of 337 students aged between 18 and 30 studying in Lund, Sweden. Information concerning daily news-related social media posts consumption a
This study explored how young Swedish adults aged 20–30 describe and understand experiences of weight-based bullying during their school years, as well as their ways of coping. A qualitative design using semi-structured interviews was employed. The sample consisted of nine young adults with a mean age of 24.7 years, including two males and seven females. All participants had lived with overweight
From the Wunderkammern of Renaissance Europe to the curated vaults of today’s natural history museums, millions of insect specimens have been preserved, capturing an irreplaceable chronicle of biodiversity, including lineages that are rare, highly specialized, or already extinct. Yet their fragility has historically constrained genomic inquiry. Here, we apply museomic methodology to a >40-year-old
During the last few years increased focus has been given to environmental and social issues due to worldwide changes in the weather and temperature, in some cases leading to natural disasters and dramatic changes in everyday life. Media and politicians have begun to address related problems, acknowledging the fact that human impact on nature is a real problem that poses as a threat to our future.
The enzyme nitrogenase contains a complicated MoFe7CS9 cofactor with 35 possible broken- symmetry (BS) states. We have studied how the energies of these states depend on the geometry, the surrounding protein, the DFT functional and the basis set, studying the resting state, a one- electron reduced state and a protonated state. We find that the effect of the basis set is small, up to 11 kJ/mol. Lik
