PURPOSE: Epinephrine is used in local anesthetics to induce vasoconstriction and thus reduce bleeding and prolong the anesthetic effect. Finding the optimal delay between the administration of the anesthetic and skin incision to ensure vasoconstriction and minimize bleeding is important and has recently become the subject of debate. This is the first study to assess blood perfusion and oxygen satu

Blinks, the closing and opening of the eyelids, are used in a wide array of fields where human function and behavior are studied. In data from video-based eye trackers, blink rate and duration are often estimated from the pupil-size signal. However, blinks and their parameters can be estimated only indirectly from this signal, since it does not explicitly contain information about the eyelid posit

• Purpose: To assess whether distal radius fracture (DRF) malunion is associated with greater patient-reported disability. • Methods: We searched PubMed, EMBASE, and Cochrane databases up to 21 May 2023. Two reviewers independently screened retrieved titles/abstracts and assessed the full text of potentially eligible articles to identify cohort studies and randomized controlled trials reporting ou

Emotional communication, especially through social media platforms, has become a contemporary populist threat. While this phenomenon has been studied in for example news media and social movements, we know less about its influence on civil society organizations, despite their pluralism being a centerpiece in a vibrant democracy. More specifically, we do not know if social media make civil society

Popular Abstract in Swedish Kräftors påverkan på födovävar i dammar och sjöarThis thesis examines how freshwater crayfish affect community interactions in benthic food webs. I have mainly studied the influence of the introduced signal crayfish (Pacifastacus leniusculus) on littoral communities, but also the influence of the native noble crayfish (Astacus astacus). Overall, the results show that both crayfish species are omnivores having strong direct and indirect effects o

Interest in the distinctive features of early Christian manuscripts (e.g. codex format, staurogram, nomina sacra, handwriting, and lectional signs) has increased significantly over the last decade. They are no longer merely identified and compared, but also put into a sociocultural context of early Christian scribal habits and reading culture. Similarly, more attention is constantly being directed

Externally bonded reinforcement (EBR) was used to increase load bearing capacity of light weight aggregate concrete (LWA) masonry walls subjected to eccentric axial compression. Ladder type masonry reinforcement, high strength steel wire strips and glass fiber mesh were used for strengthening of eleven, 2.4 m high, 0.5 m long and 0.1 m thick walls. The reinforcement was applied on the dry wall sur

The provision of safe care is complex and difficult to achieve. Awareness of what happens in real time is one of the ways to develop a safe system within a culture of safety. At Great Ormond Street Hospital, we developed and tested a tool specifically designed for patients and families to report harm, with the aim of raising awareness and opportunities for staff to continually improve and provide

Purpose: The study explores how organizational space and situational strength influence bystanders’ intentions to intervene in workplace bullying within the healthcare sector. Design/methodology/approach: The research employs vignette-based interviews with 24 healthcare professionals from various medical fields in Sweden. The vignettes depict different bullying scenarios occurring in various spati

Novel readers inside the narrated world are, Monika Class argues, a foundational trope in the diachronic development of the realist novel in English. Jane Austen’s Northanger Abbey can be seen as a game-changer for the intradiegetic novel reader, since Austen achieved a composition that ambivalently elevates the genre both on the level of the story, in which the two novel readers, Catherine Morlan

OECD:s nuvarande riktlinjer för internprissättning saknar tydliga och otvetydiga instruktioner för prissättning av specificerade transaktioner och utformandet av riktlinjerna har istället styrts av en ambition om att tillämpa den metod som med tanke på omständigheterna i det specifika fallet ger det mest lämpliga resultatet. Detta stora tolkningsutrymme har lett till svårlåsta tvister, nekade avdrThe OECD guidelines on transfer pricing are currently lacking clear and unambiguous instructions on how to set transfer prices for a given transaction type. The current guidelines are instead more focused on allowing the tax payer to pick the transfer pricing method that is most appropriate considering the circumstances of a specific case. This has left ample room for interpretation, which in turn

Objective: The ideal implant material for the surgical repair of pelvic organ prolapse in women is yet to be found. This retrospective study aims to evaluate a porcine small intestinal submucosa (SIS) graft (Surgisis™). Study design: We reviewed the medical records of women that were operated upon for pelvic organ prolapse using implantation of SIS graft and we examined the short-term complication

Dynamic vegetation models are useful tools for analysing terrestrial ecosystem processes and their interactions with climate through variations in carbon and water exchange. Long-term changes in structure and composition (vegetation dynamics) caused by altered competitive strength between plant functional types (PFTs) are attracting increasing attention as controls on ecosystem functioning and pot

A method is described for imaging in 3-D the interiors of meteoritic chromite grains and their inclusions using synchrotron radiation X-ray tomographic microscopy. In ordinary chondrites, chromite is the only common mineral that survives long-term weathering on Earth. Information about the silicate matrix of the original meteorite, however, can be derived from mineral inclusions preserved in the p

The Palaeocene arctic supported a vegetation type quite distinct from the tundra and polar desert of today. Here we demonstrate, through the palynological record, the structure of this extinct vegetation and its dynamics over this period. The Late Palaeocene coal-bearing units of the Sagwon Bluffs on Alaska's North Slope (present latitude 69 degrees N) are predominantly fine-grained, non-marine an

Every disorder is embedded within multiple sociocultural aspects, and in mental disorders they acquire paramount significance. Nonetheless and despite the cultural diversity of ancient and modern societies, the consistency of psychiatric reactions to combat stress throughout history is remarkable. The situation in ancient Greece was quite different from the contemporary one. Hippocratic physicians

Aromatic side chains are prevalent in protein binding sites, perform functional roles in enzymatic catalysis, and form an integral part of the hydrophobic core of proteins. Thus, it is of great interest to probe the conformational dynamics of aromatic side chains and its response to biologically relevant events. Indeed, measurements of (13)C relaxation rates in aromatic moieties have a long histor

In this paper we evaluate the Swedish Programme for improving energy efficiency in energy-intensive industries (PFE). Since 2005, some 100 energy-intensive companies have entered this five year voluntary agreement (VA) and been exempted from the EU minimum tax on electricity. In return, each company is required to: conduct an energy audit and analysis; identify and invest in profitable electricity

Reduced irregularity of RR intervals in permanent atrial fibrillation (AF) has been associated with poor outcome. It is not fully understood, however, whether modification of atrioventricular (AV) conduction using rate-control drugs affects RR variability and irregularity measures. We aimed at assessing whether atrial fibrillatory rate (AFR) and variability and irregularity of the ventricular rate
