Quantum-dot-sensitized solar cells are emerging as a promising development of dye-sensitized solar cells, where photostable semiconductor quantum dots replace molecular dyes. Upon photoexcitation of a quantum dot, an electron is transferred to a high-band-gap metal oxide. Swift electron transfer is crucial to ensure a high overall efficiency of the solar cell. Using femtosecond time-resolved spect
Background: The wrist region is one of the most complex joints of the human body. It is prone to deformity and functional impairment in juvenile idiopathic arthritis (JIA), and is difficult to examine clinically. The aim of this study was to evaluate the role of ultrasonography (US) with Doppler in diagnosis of synovitis, guidance of steroid injections, and follow-up examinations of the wrist in J
PURPOSE. Pre-mRNA processing factor 31 (PRPF31) is a ubiquitous protein needed for the assembly of the pre-mRNA splicing machinery. It has been shown that mutations in this gene cause autosomal dominant retinitis pigmentosa 11 (RP11), which is characterized by rod-cell degeneration. Interestingly, mutations in this ubiquitously expressed gene do not lead to phenotypes other than retinal malfunctio
Detta working-paper kom till efter att företrädare inom Individ och familjeomsorgen i Hässleholms kommun ville effektutvärdera sin familjeverksamhet. Ett samarbete påbörjades mellan Socialhögskolan och Familjebehandlingsenheten i Hässleholm.Papret är ett försök att genom föra små effektstudier i hög vetenskaplig design. Det finns flera små behandlingsenheter inom socialförvaltningar runt om i Sver
This paper compares the capacity improvement capability of spatial multiplexing and beamforming techniques for 60 GHz spatial transmissions in a multi-carrier radio system such as orthogonal frequency division multiplexing. The term beamforming in this paper refers to the conventional gain focusing, for the strongest propagation path, by narrow antenna beams. Our channel capacity metric depends on
Gamma rays from the decay of an isomer in W-190(116) have been observed following projectile fragmentation of a 1 GeV per nucleon Pb-208 beam. An earlier experiment indicated decay from a (10(-)) isomer to the ground state rotational band. Improved statistics have enabled gamma coincidence and time-difference measurements to be made which alter the previous interpretation. Blocked BCS calculations
Plasma adiponectin levels have previously been inversely associated with carotid intima-media thickness (IMT), a marker of subclinical atherosclerosis. In this study, we used a sex-stratified Mendelian randomization approach to investigate whether adiponectin has a causal protective influence on IMT.
The production of the strange and double-strange baryon resonances (Sigma (1385)(+/-), Xi (1530)(0)) has been measured at mid-rapidity (vertical bar y vertical bar < 0.5) in proton-proton collisions at root s = 7 TeV with the ALICE detector at the LHC. Transverse momentum spectra for inelastic collisions are compared to QCD-inspired models, which in general underpredict the data. A search for the
Based on high-resolution spectra obtained during gravitational microlensing events we present a detailed elemental abundance analysis of 32 dwarf and subgiant stars in the Galactic bulge. Combined with the sample of 26 stars from the previous papers in this series, we now have 58 microlensed bulge dwarfs and subgiants that have been homogeneously analysed. The main characteristics of the sample an
The politics of European collaborative Big Science are inherently uncertain. The European Spallation Source (ESS) for materials science, planned to be built in Sweden with a collaborative European funding solution that was recently finalized is the most recent example. Sweden has so far invested around one billion SEK (&E110 million), taking a significant risk given these uncertainties and giv
Managing risk using an “all-hazards” and “whole of society”-approach involves extensive communication of risk descriptions among many stakeholders. In the present study we investigate how professionals working with disaster risk management in such contexts perceive the usefulness of different descriptions of risk. Empirical data from the Swedish disaster risk management system were used in an atte
Background: Pediatric intestinal biopsy procedures including considerable transpharyngeal manipulation of a wire-guided metal capsule require adequate sedation or anesthesia. This retrospective cohort study was designed to evaluate intravenous sedation with ketamine and low-dose midazolam in young children undergoing these procedures before and also after discharge from the hospital. Methods: A t
This article investigates whether public funds should support R&D and if so, how such support should be designed in order to be efficient and to comply with the legal requirements stated in EU law and in domestic budget law. The article puts the emphasis on tax expenditure and, in particular, on tax incentives. The findings show that Member States should only subsidize projects where the socia
Urban water management policy in Japan, with examples from Fukuoka city, is described and the potential for sustainability of Fukuoka's urban water system is discussed. A framework of the qualitative characteristics of a sustainable system (including social, environmental and economic factors) is developed and used in the analyses presented here. The Fukuoka example shows that technically advanced
Cement hydration needs water to proceed and if water is lost by drying, the hydration rate will decrease This can be of importance in cases when concrete surfaces are exposed to drying so that their strength development will be retarded We describe a method based on isothermal calorimetry to assess how the rate of cement hydration is influenced by removal of water (drying) at different times up to
