Imaging the itinerant-to-localized transmutation of electrons across the metal-to-insulator transition in V2O3

In solids, strong repulsion between electrons can inhibit their movement and result in a “Mott” metal-to-insulator transition (MIT), a fundamental phenomenon whose understanding has remained a challenge for over 50 years. A key issue is how the wave-like itinerant electrons change into a localized-like state due to increased interactions. However, observing the MIT in terms of the energy- and mome

Plasma circulating cell-free mitochondrial DNA in depressive disorders

Plasma circulating cell-free mitochondrial DNA (ccf-mtDNA) is an immunogenic molecule and a novel biomarker of psychiatric disorders. Some previous studies reported increased levels of ccf-mtDNA in unmedicated depression and recent suicide attempters, while other studies found unchanged or decreased ccf-mtDNA levels in depression. Inconsistent findings across studies may be explained by small samp

Behavioral and Biological Factors Related to HIV Transmission among Female Sex Workers in Ethiopia

Due to legal, cultural, and social factors, female sex workers (FSWs) experience anelevated level of violence, heavy alcohol consumption, and sexual abuse. Theseindividual and societal factors create a web of vulnerabilities that facilitate thespread of HIV within this population group. Moreover, stigma and discriminationare common among HIV-positive FSWs, contributing to poor HIV treatmentadheren

Hyperbranched Polymers in Cationic Photopolymerization of Epoxy Systems

Mixtures of epoxy resins in the presence of epoxy hyperbranched polymers (HBP), in the range of 5-15 wt%, were investigated in the cationic photocuring process. No significant differences in rate of polymerization or final epoxy groups conversion were observed. At low concentration, HBP acts as plasticizer and causes a decrease of the glass transition temperature of the epoxy matrix and of the E'

Synthesis and Cationic Photopolymerization of New Silicon-Containing Oxetane Monomers

The cationic photopolymerization of oxetane-based systems containing silicon monomers was investigated. For this purpose, three new silicon-containing oxetane monomers were synthesized through a simple and straightforward synthetic method. The silicon-containing monomers were added to a typical oxetane resin, 3,3-[oxydi(methylene)]bis(3-ethyloxetane), in concentrations of 1-5 wt %. They exploited

New difunctional fluoro-epoxide monomers : Synthesis, photopolymerization and characterization

New difunctional fluoro-epoxide monomers were synthesized starting by allylation of the corresponding fluorinated diols and subsequent epoxidation. The new products were photocured, in the presence of triphenylsulphonium hexafluoroantimonate as photoinitiator; a higher reactivity of the fluorinated monomers was evidenced with respect to a typical UV curable diepoxy resin, hexanedioldiglycidyl ethe

Aspects of ethnicity on blood pressure regulating mechanisms and kidney function in a defined population

Background: Middle Eastern immigrants represent a growing population in Sweden today. This group are at higher risk for type 2 diabetes than the native population, but are also shown to exhibit unique properties; despite an abundance in traditional cardiometabolic risk factors such as obesity, dearranged blood lipids and diminished physical acitivity, this group seem to exhibit lower blood pressur

Process for production of an oxetane

A process for production of an oxetane, which process comprises subjecting an alcohol having two or more hydroxyl groups to reaction with a carbamide at a molar ratio employing 1-2 moles of said carbamide on 1-2 moles of said alcohol. The alcohols preferably have at least one 1,3-diol grouping. The reaction is carried out in the presence of at least one catalyst promoting and/or initiating transca

Process for the preparation of a dendritic polyol

A process for synthesis of a polymeric polyalcohol substantially and preferably built up form polyester units and composed of a monomeric or polymeric initiator molecule to which at least one dentritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymericor monomeric branching chain extender having three reactive functions of whic

Fly navigation: Yet another ring

Flies keep track of a food site by path integration. A novel behavioral paradigm has been combined with computational models to show that Drosophila can track at least three food patches simultaneously by using the center of gravity of all food sites as the reference point for their path integrator.

Socialising of nursing students into homecare practice in Denmark: a Berger and Luckmann-inspired interview study

In 2016, Denmark's nurse education eliminated diagnoses, age and care settings from the curriculum. How students are trained for homecare is unknown. This article illuminates how students of non-Danish origin were socialised into homecare practice during nurse education in Denmark. Semi-structured interviews with eight students and a theoretical inspired latent thematic analysis of data were condu

Thermochromic textiles and sunlight activating systems: an alternative means to induce colour change

This thesis has investigated how the design process used by a textile printmaker practitioner requires further modification when the sun, uncontrollable by nature, is used to activate thermochromic leuco dyes, a dynamic surface variable. In the context of the use of the sun as the dynamic activator, the investigation is focussed on design applications of sun-screening textiles for both indoor and This thesis has investigated how the design process used by a textile printmaker practitioner requires further modification when the sun, uncontrollable by nature, is used to activate thermochromic leuco dyes, a dynamic surface variable.

Light and Shadow Play : The sun as an aesthetic trigger for urban textiles

The project investigates how the sun can be utilized to enhance aesthetics through textile surfaces in urban environments. The project explores the interplay of textiles as a sun-screening element within the outdoor public architectural space. What happens when we use the sun's heat and light to trigger a light and shadow play through a textile surface?

Emotional authenticity modulates affective and social trait inferences from voices

The human voice is a primary tool for verbal and nonverbal communication. Studies on laughter emphasize a distinction between spontaneous laughter, which reflects a genuinely felt emotion, and volitional laughter, associated with more intentional communicative acts. Listeners can reliably differentiate the two. It remains unclear, however, if they can detect authenticity in other vocalizations, an

Did vocal size exaggeration contribute to the origins of vocalic complexity?

Vocal tract elongation, which uniformly lowers vocal tract resonances (formant frequencies) in animal vocalizations, has evolved independently in several vertebrate groups as a means for vocalizers to exaggerate their apparent body size. Here, we propose that smaller speech-like articulatory movements that alter only individual formants can serve a similar yet less energetically costly size-exagge
