Feathers comprise a series of evolutionary innovations but also harbour colour, a key biological trait known to co-vary with life history or complex traits. Those relationships are particularly true in melanin-based pigmentation species due to known pleiotropic effects of the melanocortin pathway – originating from melanin-associated phenotypes. Here, we explore the molecular basis of melanin colo

This study examines trait-level sense of self in 32 participants with varying meditation experience, with a special focus on the sense of self-boundaries and the sense of being a subject of experience, what is here referred to as perspectival ownership of experience. Results from qualitative and quantitative analyses of in-depth phenomenological interviews suggested a quadratic relation between se

Purpose: Starting from a power perspective, the study problematizes the prevailing normative and management-dominated view of self-initiated employee ambassadorship on social media. The aim is to provide a more nuanced and critical understanding of the negative aspects of this phenomenon.Design/methodology/approach: The empirical material encompasses qualitative interviews with employees from 14 o

Furfural is an intermediary toxic aldehyde compound produced during heat-induced food processing and storage. Furfural is also formed by the degradation of cellulosic insulation in oil-immersed electric potential transformers, whose level is an important indicator of aging for replacement. In this study, we report a new means to detect the trace level of furfural in a colorimetric manner. Furfural

Introduction: Whether and under what conditions scientific knowledge provided by experts actually leads to political action is a question that academic research in various fields have focused on at length, without reaching a definitive answer. The position of expertise is especially delicate within the global environmental governance sphere containing multiple values, worldviews and epistemologica

Introduction: Dementia is a condition (a collection of related signs and symptoms) that causes a continuing deterioration in cognitive function, and millions of people are impacted by dementia every year as the world population continues to rise. Conventional approaches for determining dementia rely primarily on clinical examinations, analyzing medical records, and administering cognitive and neur

Vid förbränning av avfall produceras stora mängder slaggrus som både är ett avfall, som kräver hantering, och en resurs, genom dess goda materialegenskaper. Slaggrus definieras i denna studie som sorterad bottenaska från avfallsförbränning. En potentiell spridningsväg för föroreningar från slaggruset vid anläggningsarbete är damning. Damning är en miljöoch hälsofara även utan föroreningar i materi

Because of varied topography and landscape heterogeneity，Tianshan Mountain has extremely complex hydrological processes. Considering that the climate change poses a great threat to the water security，it’s necessary to simulate the change of water elements quantitatively and systematically along with elevation. In this study，we applied the modified FLEXG-Δh model to four classic river basins in Tia

Slowed adaptation of the QT interval to sudden abrupt heart rate (HR) changes has been identified as a marker of ventricular arrhythmic risk. However, abrupt HR changes are difficult to induce in patients. Quantifying the QT adaptation time in gradual HR changes, as observed in ECGs recording during an exercise stress test, has been recently proposed. The time lag between the QT series and an inst

Driftmetoder mot höga partikelhalter orsakade av vägdamm i gatu- och vägmiljöer har under lång tid utvärderats i vanlig gatumiljö. Resultaten är dock ofta förhållandevis svårtolkade på grund av inverkan av meteorologi och omfattande inblandning från andra partikelkällor än just den gata som studeras. För att komma vidare med mer detaljerade studier av metodik och strategi och för att få mer lättol

High Capacity vehicles (HCV) have dimensions outside general access rules. The High Capacity Transport (HCT) concept consists of roads, vehicles, operations, and regulations. The Intelligent Access (IA) framework gives access to roads only if compliance assurance schemes are used to ensure “the right vehicle is on the right road at the right time with the right axel loads and driven at the right s

En litteraturgenomgång av miljöeffekter relaterade till val av vägbeläggning redovisas utgående från bullerreducerade beläggningar, och med fokus på slitagepartiklar, då det inom området pågår stor inhämtning av ny kunskap. En enkel beskrivning av beläggningar med utgångspunkt från Trafikverkets krav och råd har kompletterats med relationen till de tre områdena buller, partiklar och rullmotstånd.

A feasibility study of an underground capsule-pipe system for storing and transporting small items and waste is presented. “Hyperloop for packages” for the last/first/mile/yard all the way to and from the final user in apartments and establishments. In many cases, one capsule of 2 kg can do the same job as a car with 1000 times larger mass. The conclusion is that such a system is technically feasi

Reconfigurable intelligent surfaces (RISs) are promising to improve energy efficiency and coverage for 6G [1]. In this paper, we aim to optimize the deployment of BSs and RISs for enhanced coverage in terms of received power. Specifically, an active RIS structure [2] with tuneable power amplification is applied, and a framework of mixed integer linear programming (MILP) is proposed for the optimiz

Introduction: Enhancing treatment adherence, especially for chronic diseases, can be achieved through therapeutic alliance, potentially elevating the quality of care. An instrument to evaluate the therapeutic alliance could be beneficial in routine clinical settings, educational environments, and extensive research efforts at national and European levels. In this study, we translated therapist and

Modifiable factors, such as alcohol or physical exertion, may trigger atrial fibrillation (AF) episodes. Identifying and eliminating these triggers can lead to effective strategies which reduce risk of AF recurrence. This study aims to evaluate pre-and post-trigger AF in long-term photo-plethysmogram (PPG) signals obtained during daily living from patients with paroxysmal AF. Thirty-seven patients

There is a misconception that pictures are easy to comprehend, which is problematic in pedagogical practices that include pictures. For example, if a child has difficulties with verbal narration to picture sequences, it may be interpreted as specific to spoken language even though the child may have additional difficulties with comprehension of visual narratives in the form of picture sequences. T

Background: The goals for staff in Supported Housing for people with psychiatric disabilities include helping to develop the residents’ independence and self-confidence in activities. However, staff have expressed frustration about providing this type of support when motivating residents to engage in meaningful activities and also about the difficulty in finding suitable levels of independence wit
