Firefighters are occupationally exposed to a large number of toxic compounds (IARC 2010). The occupational exposure of firefighters has been classified as potentially carcinogenic (class 2B, IARC; (Straif K. et al. 2007)). Poorly quantified emission factors and low understanding of when various aerosol emissions are likely to form during a fire event (initiation, combustion, extinguishing) inhibit
The addition of Cr is known to work as an effective prevention against oxidation in Fe-based alloys. This can be attributed to the peripheral oxide, the structure of which is dependent on the composition of the alloy. Using Molecular Dynamic (MD) calculations with a Reactive Force Field (ReaxFF) potential, we successfully identify several oxide structures arising during initial oxide formation in The addition of Cr is known to work as an effective prevention against oxidation in Fe-based alloys.

Through an autoethnographical reflection the aim of this paper is to explore the clash between high ethical ambitions in educative relationships and demandingbehaviours. What happens when the map does not resemble reality, when, forexample, someone in the educative relation does not behave as expected and themethods are challenged? What increases or decreases the risk that the teacher (orsimilar)
With their superficially shark-like appearance, the Mesozoic ichthyosaurs provide a classic illustration of major morphological adaptations in an ancestrally terrestrial tetrapod lineage following the invasion of marine habitats1, 2–3. Much of what is known about ichthyosaur soft tissues derives from specimens with body outlines4, 5–6. However, despite offering insights into aspects of biology tha
Independence and collaboration both play crucial roles in PhD students’ research practice and in their socialization into the PhD role. This study examines how theexpectation of PhD students' academic independence intersects with the need for more collaborative engagements within research groups. Drawing on interviews with supervisors and an analysis of co-authorship patterns in PhD studentdissert
Animals live in diverse environments and have evolved to cope with environmental challenges in different ways. How such adaptations shape overall brain morphology is still unclear. Here, we test how two behavioural adaptations – circadian activity pattern and migratory behaviour – are reflected in the brains of moths and butterflies (Lepidoptera). We predicted that circadian activity pattern affec
OBJECTIVES: Asphalt is frequently used as road pavement and consists of bitumen as a binder, and fillers. Bitumen consists of a complex mixture of hydrocarbons, where a minor component is polycyclic aromatic hydrocarbons (PAHs). Many PAHs are classified as carcinogenic to humans. Bitumen fumes from road paving have been classified as possibly carcinogenic. Paving and milling are open processes gen
How Do We Treat the Super-Elderly with Distal Radius Fractures and What is the Outcome? A Register Study in 239 Patients of 80 years or olderLinnea Sara Arvidsson, MD; Ellen Lööf, Bachelor of Medicine; Antonio Abramo, PhD; Magnus Tägil, PhDLund University, Lund, SwedenIntroductionWith a rapidly ageing population, the number of wrist fractures will rise dramatically in the super elderly group. BasiIntroductionWith a rapidly ageing population, the number of wrist fractures will rise dramatically in the super elderly group. Basic knowledge of outcome after fracture in this heterogenic group is absent. Our aim was to use our prospective distal radius fracture register to study the super-elderly patients with distal radius fractures. We hypothesized that the health status of the patient, rather
Objective: To investigate the dynamic changes of soluble fms-like tyrosine kinase−1 (sFlt−1), placental growth factor (PlGF) and their ratio in maternal plasma, from preeclampsia diagnosis to postpartum, evaluating its clinical utility. Methods: Single-center prospective longitudinal cohort study with repeated sample collection in women with established preeclampsia (PE). Seventy-five (n = 75) wom
Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. It is thus of high importance to understand the characteristics of each
Iron-centered N-heterocyclic carbene compounds have attracted much attention in recent years due to their long-lived excited states with charge transfer (CT) character. Understanding the orbital interactions between the metal and ligand orbitals is of great importance for the rational tuning of the transition metal compound properties, e.g., for future photovoltaic and photocatalytic applications.
Objectives: To evaluate a cancer detecting artificial intelligence (AI) algorithm on serial biopsies in patients with prostate cancer on active surveillance (AS). Patients and methods: A total of 180 patients in the Prostate Cancer Research International Active Surveillance (PRIAS) cohort were prospectively monitored using pre-defined criteria. Diagnostic and re-biopsy slides from 2011 to 2020 (n

This enquiry discusses the potential of a large number of linguistic theories, approaches, concepts etc. from Plato to usage-based linguistics for the understanding of the tense system in Ancient Greek, and particularly in the Greek of the New Testament. It is argued that many significant insights within linguistics in the period from the earliest beginning of linguistic thought up to Saussure hav
The removal of lysozyme adsorbed to a hydrophobic surface by a non-ionic surfactant, C12E5, was investigated using in situ ellipsometry. Both the adsorption and removal of protein were studied at different protein and surfactant concentrations. The surfaces used were methylated silica surfaces and the experiments were carried out at pH 5.6 in 0.01 M NaCl solution.

Lobbyists are working in an ambivalent atmosphere. In Brussels, lobbying is an activity occupying about 20 000 people on a daily basis. They are trying to influence the legislative outcomes from the work of the about 15 000 politicians and employees of the EU institutions (Coen 2007). On one hand the lobbyists are wanted and needed by the politicians and their civil servants. Previous research tel
On-site hydrogen gas production from hydrogen-rich liquids offers a clean alternative to fossil fuels for combustion that is readily implemented in existing energy infrastructure. A heterogenized (POCOP)-Ir pincer catalyst can be operated at higher temperatures for higher turnover frequency, but the reaction pathway of the reported complex has not been well understood. Here, we report intermediary
