Rare earth element (REE) recycling remains low at 1%, despite significant uncertainties related to future supply and demand and EU 2020 energy efficiency objectives. We use a global production network framework of REE flows from mine to REE phosphors in energy-efficient lamps to illustrate the potential of closed-loop recycling for secondary supply under different scenarios of primary supply and f

Background The growing awareness of transfusion-associated morbidity and mortality necessitates investigations into the underlying mechanisms. Small animals have been the dominant transfusion model but have associated limitations. This study aimed to develop a comprehensive large animal (ovine) model of transfusion encompassing: blood collection, processing and storage, compatibility testing right

Purpose– The purpose of this study is to examine whether or not gender‐related differences affect the likelihood of promotion.Design/methodology/approach– The research is done on a unique dataset on the Swedish audit industry, an industry with a well‐defined and well‐known career ladder. We apply an ordered probit model to take all steps in the career ladder into consideration simultaneously.Findi

The geochronologic (U-Pb isotopic system of zircons) and isotopic-geochemical (Sm-Nd isotopic system of the bulk rock) studies were performed along the profile extending from the eastern Sarmatia (in the west) to the Middle Volga megablock of Volgo-Uralia (in the east), i.e., across the entire junction zone for dating the integration of Sarmatia and Volgo-Uralia, representing two segments of the E

The role and importance of ecological interactions for evolutionary responses to environmental changes is to large extent unknown. Here it is shown that interspecific competition may slow down rates of adaptation substantially and fundamentally change patterns of adaptation to long-term environmental changes. In the model investigated here, species compete for resources distributed along an ecolog

The photophysical properties of conjugated polymers (CPs) largely depend on the interactions between the CP and its environment. We present a study of two polymers with identical conjugated backbones, bare and insulated, that showed different fluorescence excitation modulation depth histograms. However, the polarization differences are not related to differences in conformation, as commonly believ

Charge transport dynamics in solar cell devices based on as-spun and annealed P3HT:PCBM films are compared using ultrafast time-resolved optical probing of the electric field by means of field-induced second harmonic generation. The results show that charge carriers drift about twice as far during the first 3 ns after photogeneration in a device where the active layer has been thermally annealed.

Retorik är ett undervisningsämne, men hur bör undervisningen i retorik utformas? Undervisningen i retorik borde syfta till att eleverna eller studenterna ska bli goda talare eller skribenter. Det centrala begreppet i retorikens undervisningstradition är imitatio. Efterbildningen står som en bro mellan den teoretiska undervisningen och det praktiska talandet och skrivandet. Både hos Quintilianus oc

Popular Abstract in English The new climate politics of decarbonisation address the prospects for moving society away from its current dependence on fossil carbon energy. In this compilation dissertation, Hildingsson explores the role of the state as a critical site for progressive climate action, and examines its capacity to govern decarbonisation by transforming systems, structures and practicesThis dissertation examines the “new climate politics of decarbonisation” and the role of the state as a site for progressive climate action. This new politics concerns transformative social change aimed at moving society away from its current dependence on fossil carbon energy. A transition to low-carbon societal development hinges on restructuring and decarbonising those key systems, structures a

PURPOSE: To estimate the prevalence, genotype, and clinical spectrum of Best vitelliform macular dystrophy (Best disease). DESIGN: Retrospective epidemiologic and clinical and molecular genetic observational study. METHODS: SETTING: National referral center. PARTICIPANTS: Forty-five individuals diagnosed with Best disease. OBSERVATION PROCEDURES: Retrospective review of patients diagnosed accordin

Neutrophils are critical for the control of bacterial infections, but they may also contribute to disease pathology. Here we explore neutrophil responses, in particular the release of sepsis-associated factors heparin-binding protein (HBP) and resistin in relation to specific bacterial stimuli and sepsis of varying aetiology. Analyses of HBP and resistin in plasma of septic patients revealed eleva

Originally a paper read at a Nordic conference at Sigtunastiftelsen, Sweden, this article surveys the implications of the current and vibrant Jewish-Christian dialogue for the Law and Gospel dichotomy that has governed Lutheran theology.

The need for quantification of land cover from pollen data has led to the development of a Landscape Reconstruction Algorithm (LRA). The LRA includes several models of which the REVEALS model estimates regional vegetation abundance using pollen assemblages from large sites (lakes or bogs). In this paper we explore the effects of selection and number of pollen samples, and choice of pollen producti

This paper presents a convex optimization approach to study optimal realizations of passive electromagnetic structures. The optimization approach complements recently developed theory and techniques to derive sum rules and physical limitations for passive systems operating over a given bandwidth. The sum rules are based solely on the analytical properties of the corresponding Herglotz functions. H

Abstract in Undetermined Regional Aesthetics: Locating Swedish Media maps more than two hundred years of Swedish media. It ranges from written travelogues in the eighteenth and nineteenth centuries via feature films, documentaries, TV programmes, literature and press to contemporary video activism on the Internet. The nineteen contributors navigate the reader through a variety of media landscapes

Popular Abstract in Swedish Åderförkalkning, den i folkmun använda benämningen för ateroskleros, är en sjukdom som de flesta lider av. Vi vet bara inte om det. Ateroskleros ger nämligen sällan symptom innan ett aterosklerotiskt plack (en lokal aterosklerosansamling i kärlväggen) brister och det bildas en blodpropp. Om placket som brister sitter i kärlen som förser hjärtat eller hjärnan med blod kaMyocardial infarction and stroke, mainly caused by a rupture of an atherosclerotic plaque, are two of the most common causes of mortality and morbidity in the world. Previous studies have pointed out inflammation, driven by inflammatory lipids, as the keystone in the formation of the rupture prone vulnerable plaque. The risk for a plaque rupture is greatly enhanced in the diabetic population and i
