We investigate the evolution of the abundance of fluorine in the Milky Way thick and thin discs by means of detailed chemical evolution models compared with recent observational data. The chemical evolution models adopted here have already been shown to fit the observed abundance patterns of CNO and α-elements as well as the metallicity distribution functions for the Galactic thick and thin disc s
Asteroid material is detected in white dwarfs (WDs) as atmospheric pollution by metals, in the form of gas/dust discs, or in photometric transits. Within the current paradigm, minor bodies need to be scattered, most likely by planets, into highly eccentric orbits where the material gets disrupted by tidal forces and then accreted on to the star. This can occur through a planet-planet scattering pr
The sharing economy is sometimes described as a big city phenomenon. Among the successful examples of sharing economy, cities such as New York, Amsterdam, Seoul, Bergen, Oslo, and Gothenburg are often highlighted. But the majority of the population of Sweden and many other countries do not live in big cities, but in small towns, medium-sized cities or in a rural area. With a smaller and less dense
This paper focuses on the use of pulse functions and point matching method to construct the impedance matrix needed for the characteristic mode analysis of dielectric bodies. Taking the results given by a commercial Method of Moments (MoM) solver as a benchmark, the proposed method is shown to facilitate accurate characteristic eigenvectors and eigenvalues on these structures using low order basis
Gothenburg is a flourishing green city, with nearly 600,000 inhabitants, located on the west coast of Sweden. Gothenburg has a long tradition of a strong civil society and grass roots movement, which is also reflected when it comes to the development of the sharing economy in the city. Many of the sharing initiatives come from civil society organizations, but the local government has also taken an
A new neighbourhood in Malmö is emerging in Sege Park, an area with a rich history and exciting future. The existing parks and buildings provide the conditions for a good living environment. Sustainability, the sharing economy and urban agriculture are some key words for the building actors who are developing some 800 – 1,000 homes in Sege Park together with the municipality. The innovative aspect
The uniqueness of the Stockholm test-bed is based on its close collaboration with a citizen initiative called Hammarby Sjöstad 2.0 around the mission to create a climate-neutral city district by 2027. The founder of Hammarby Sjöstad 2.0 is ElectriCITY, a (civic society NGO and) membership association which operates a number of energy initiatives in the area since 2012, primarily by targeting the n
Aim: To compare vibrotactile sense, 5 years after carpal tunnel release in people with and without diabetes. Methods: Out of 35 people with diabetes and carpal tunnel syndrome, age- and gender-matched with 31 people without diabetes but with idiopathic carpal tunnel syndrome, 27 and 30 people, respectively, participated in this prolonged follow-up. Vibration perception threshold of the index and l
Over the past 50 years Umeå has displayed constant growth, making it the fastest-growing region in northern Sweden. It is therefore crucial that Umeå grows with regards to environmental, social, cultural and economic aspects. Sharing City Umeå, which is a test-bed for the sharing economy, is focusing on innovative solutions for shared mobility, green spaces, resource efficiency, sustainable consum
It is becoming increasingly evident that the field of language documentation and the docu¬mentary multimedia resources it produces rely on expanding their relevance and usability to disciplines beyond linguistics in order to increase their chances of being sustainable in the long term. This paper argues that more attention should be paid to the needs and interests of such disciplines in language d
Smart and Sustainable Cities? Pipedreams, Practicalities and Possibilities provides one of the first examinations of how smart cities relate to environmental and social issues. It addresses the gap between the ambitious visions of smart cities and the actual practices on the ground by focusing on the social and environmental dimensions of real smart city initiatives as well as the possibilities th
The association between blood pressure (BP) and bladder cancer (BC) risk remains unclear with confounding by smoking being of particular concern. We investigated the association between BP and BC risk among men using conventional survival-analysis, and by Mendelian Randomization (MR) analysis in an attempt to disconnect the association from smoking. We additionally investigated the interaction bet
Background: Diseases of the bowel are not always displayed on conventional abdominal computed tomography (CT). The studied oral contrast agent aims to improve this. Purpose: To investigate whether the use of a novel oral contrast for abdominal CT enables the same diagnostic advantages as seen in magnetic resonance imaging (MRI). Material and Methods: Twenty-five consented volunteers drank up to 14
Direct oral anticoagulants (DOAC) are first line treatment for pulmonary embolism (PE). Treatment of acute PE is traditionally hospital based and associated with high costs. The aims of this study were to evaluate potential cost savings with outpatient DOAC treatment compared to inpatient DOAC treatment in patients with low risk PE. A retrospective study in patients with DOAC treated low risk PE (
Introduction: as South Africa's maternal mortality ratio increased between 1990 and 2015, the country failed to reach the United Nations millennium development goal 5a. The maternal mortality ratio of Limpopo province is higher than the national average and previous studies report shortages of manpower and medical equipment in Limpopo province. The overall study aim was to elucidate views and expe
Background: Polyaminopropyl biguanide (INCI name) and polyhexamethylene biguanide (PHMB) are polymeric biguanides. PHMB is a broad-spectrum antimicrobial substance used as a preservative in many products. Due to our limited knowledge on PHMB contact allergy frequency and the fact that cases of allergic contact dermatitis to PHMB might be missed, we have included PHMB as a screening allergen since
This study investigates the impacts of future climate uncertainties in the new generation of future climate data sets according to AR5(5 th assessment report of IPCC) on simulating the energy performance of buildings by studying the building stock in Germany (Potsdam). This work is based on two data bases, namely 'Tabula web tool-European building' and 'EPISCOP'. Software IDA ICE was used to make
Numbers reveal, but they also hide; they tell us who we are, but also who we ought to become; they show us how happy and healthy we are, but also urge us to adjust ourselves to the norm. Numbers manage us and we, in turn, manage ourselves through numbers. At the same time, the rationale behind these metrics remains inaccessible to us, stored safely away in a locket, kept secret from all but the fe
