Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars V. Evidence for a wide age distribution and a complex MDF

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

Unpreparedness and risk in Big Science policy: Sweden and the European Spallation Source

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

On the perceived usefulness of risk descriptions for decision-making in disaster risk management

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

Sedation with ketamine and low-dose midazolam for short-term procedures requiring pharyngeal manipulation in young children

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

Tax Incentives, Tax Expenditures Theories in R&D: The Case of Sweden

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

Sustainability of urban water system: examples from Fukuoka, Japan

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

A method based on isothermal calorimetry to quantify the influence of moisture on the hydration rate of young cement pastes

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

Customer roles in mergers and acquisitions: A systematic literature review

Customers are important stakeholders for any company; yet, they seem not to be widely discussed in merger and acquisition research. This chapter synthesizes the current body of research on customers in mergers and acquisitions through presenting a systematic literature review. The chapter is based on a systematic literature review resulting from a search in EBSCO Host for any research item that re

Analyses and Applications of the Peaceman--Rachford and Douglas--Rachford Splitting Schemes

Popular Abstract in Swedish Partiella differentialekvationerna} är kraftfulla verktyg som kan användas för att beskriva fysikaliska fenomen inom bland annat naturvetenskap, teknik, ekonomi och medicin. Listan med tillämpningar kan göras hur lång som helst: Partiella differentialekvationer kan beskriva hur en snöflinga bildas, hur strukturer deformeras när de utsätts för mekaniska krafter, hur blodSplitting methods are widely used as temporal discretizations of evolution equations. Such methods usually constitute competitive choices whenever a vector field can be split into a sum of two or more parts that each generates a flow easier to compute or approximate than the flow of the sum. In the research presented in this Licentiate thesis we consider dissipative evolution equations with vector

Effects on logistic operations from RFID- and EPCIS-enabled traceability

Purpose - The paper aims to explore the potential effects on logistic operations of implementing the Electronic Product Code Information Service (EPCIS) standard and radio frequency identification (RFID) technology to enable food traceability. A conceptual model for analysing supply chains according to EPCIS standard is also presented. Design/methodology/approach - A literature review was conducte

How insect flight steering muscles work.

Insights into how exactly a fly powers and controls flight have been hindered by the need to unpick the dynamic complexity of the muscles involved. The wingbeats of insects are driven by two antagonistic groups of power muscles and the force is funneled to the wing via a very complex hinge mechanism. The hinge consists of several hardened and articulated cuticle elements called sclerites. This art

Concise Total Synthesis of Dehaloperophoramidine.

Perophoramidine, dehaloperophoramidine, and communesin F are structurally related alkaloids having intriguing polycyclic structures. A strategy for the synthesis of dehaloperophoramidine has been developed. In this synthesis all skeletal atoms and all functional groups required to reach the target molecule are incorporated early in the sequence. This approach led to the discovery of two novel subs

Subspaces of C-infinity invariant under the differentiation

Let L be a proper differentiation invariant subspace of C-infinity (a, b) such that the restriction operator d/dx vertical bar L has a discrete spectrum Lambda (counting with multiplicities). We prove that L is spanned by functions vanishing outside some closed interval I subset of (a, b) and monomial exponentials x(k)e(lambda x) corresponding to Lambda if its density is strictly less than the cri

Isoprene emission from Sphagnum species occupying different growth positions above the water table

Isoprene emission from Sphagnum species naturally growing at different positions above the water table were measured in a subarctic peatland and at monoliths from a temperate bog. Our objectives were to investigate (1) whether emission rates were species and/or moisture dependent, and (2) whether short-term temperature history had an influence on emission capacity. We expected greater emission cap

Prognosis and response to first-line single and combination therapy in pulmonary arterial hypertension

Objectives. To investigate survival, treatment escalation, effects of first-line single- and first-line combination therapy and prognostic markers in idiopathic- (IPAH), hereditary- (HPAH) and connective tissue disease-associated (CTD-PAH) pulmonary arterial hypertension (PAH). Design. Retrospective analysis of medical journals from PAH patients at Skane University Hospital 2000-2011. Results. 1-,

The early crust of the Volgo-Uralian segment of the East European Craton: Isotope-geochronological zirconology of metasedimentary rocks of the Bolshecheremshanskaya Formation and their Sm-Nd model ages

We present the results of isotope-geochronological study of metasedimentary rocks of the Bolshecheremshanskaya Formation of the Volgo-Uralian segment of the East European Craton carried out to identify their protoliths. 16 samples of high-alumina gneisses from well cores were studied using the Sm-Nd isotope method and T-Nd(DM) model ages. Accessory zircons were selected from rocks with the most an

Measurement of colour flow with the jet pull angle in t(t)over-bar events using the ATLAS detector at root s=8 TeV

The distribution and orientation of energy inside jets is predicted to be an experimental handle on colour connections between the hard-scatter quarks and gluons initiating the jets. This Letter presents a measurement of the distribution of one such variable, the jet pull angle. The pull angle is measured for jets produced in t (t) over bar events with one W boson decaying leptonically and the oth
