Do Oil Prices Predict Economic Growth? New Global Evidence

In this paper, we test whether oil price predicts economic growth for 28 developed and 17 developing countries. We use predictability tests that account for the key features of the data, namely, persistency, endogeneity, and heteroskedasticity. Our analysis considers a large number of countries, shows evidence of more out-of-sample predictability with nominal than real oil prices, finds in-sample

Burchnall-Chaundy annihilating polynomials for commuting elements in Ore extension rings

In this article further progress is made in extending the Burchnall-Chaundy type determinant construction of annihilating polynomial for commuting elements to broader classes of rings and algebras by deducing an explicit general formula for the coefficients of the annihilating polynomial obtained by the Burchnall-Chaundy type determinant construction in Ore extension rings. It is also demonstrated

Galactose utilization sheds new light on sugar metabolism in the sequenced strain Dekkera bruxellensis CBS 2499.

Dekkera bruxellensis and Saccharomyces cerevisiae are considered two phylogenetically distant relatives, but they share several industrial relevant traits such as the ability to produce ethanol under aerobic conditions (Crabtree effect), high tolerance towards ethanol and acids, and ability to grow without oxygen. Beside a huge adaptability, D. bruxellensis exhibits a broader spectrum in utilizati

Experimental characterization of the global and local behavior of multi-dowel LVL-connections under complex loading

The thorough experimental characterization of a dowel-type connection under various combinations of bending moments and normal forces is presented in this study. Double-shear steel-to-timber connections with 12 and 20 mm steel dowels were tested in a 4-point bending test set-up. The load, between the connected steel and wood beams, was transferred by the dowels themselves and also via an additiona

Syndromes of orthostatic intolerance: a hidden danger.

Orthostatic hypotension (OH) is a relatively common heterogenous and multifactorial disorder, traditionally classified as neurogenic (less common but often more severe), or non-neurogenic (more common, with no direct signs of autonomic nervous system disease). The different clinical variants of orthostatic intolerance include initial, classical and delayed OH as well as postural tachycardia syndro

Asymmetric waves in wave energy systems analysed by the stochastic Gauss-Lagrange wave model

The Gauss-Lagrange stochastic wave model is known to produce irregular waves with realistic degrees of asymmetry. We present the basic structure of the model and illustrate three of its characteristic properties: front-back asymmetry, particle orbits, and average horseshoe pattern. We also study the effect of a linear filter in a wave energy converting (WEC) system on asymmetry and on average powe

Physical activity reduces bone loss in the distal forearm in post-menopausal women - a 25-year prospective study.

Intervention studies have shown that high-intensity training programs with duration of 1-3 years can influence bone mass in post-menopausal women. We wanted to investigate whether moderate physical activity could be associated with reduced post-menopausal bone loss also in the long-term perspective. We evaluated changes in bone mass and bone structure by repeated single-photon absorptiometry measu

Migration and health: a study of effects of early life experiences and current socio-economic situation on mortality of immigrants in Sweden.

Objectives. Previous research has demonstrated mortality differences between immigrants and natives living in Sweden. The aim of this study is to investigate the effects of early life conditions in the country of birth and current socio-economic conditions in adult life in Sweden on cardiovascular, cancer, all other cause and total mortality among immigrants and natives in Sweden. Design. The coho

Late Palaeoproterozoic mafic dyking in the Ukrainian Shield of Volgo-Sarmatia caused by rotation during the assembly of supercontinent Columbia (Nuna)

The Ukrainian Shield comprises the exposed crust of the large Palaeoproterozoic protocraton Volgo-Sarmatia, which together with the Fennoscandian crustal segment constitutes the East European Craton ("Baltica"). Geological and geophysical data indicate that 1.80 to 1.75 Ga mafic dykes related to anorthosite-mangerite-charnockite-granite (AMCG) plutons are widespread within the Ukrainian Shield. We

'Small change of the universal': beyond modernity?

The paper is a sounding of Ulrich Beck's and Edgar Grande's conceptual map of the varieties of second modernity - Western and Non-Western, European and beyond - that makes up today's world. Their mapping is examined in the light of two, striking analytical perspectives associated with Ulrich Beck: everyday 'cosmopolitization' and his call for a methodological cosmopolitanism. A line of inquiry exp

The slower the better? Does the speaker's speech rate influence children's performance on a language comprehension test?

The aim of this study was to examine the effects of speech rate on children's performance on a widely used language comprehension test, the Test for Reception of Grammar, version 2 (TROG'2), and to explore how test performance interacts with task difficulty and with the child's working memory capacity. Participants were 102 typically-developing Swedish-speaking children randomly assigned to one of

Theoretical Characterization of the PC60BM:PDDTT Model for an Organic Solar Cell

We use time-dependent density functional theory together with a set of extensive multidimensional visualization techniques to characterize band gap, optical absorption properties, intramolecular and intern-wreaths charge transfer, exciton binding energy, charge transfer integral, and the rate of charge transfer and recombination in the PC60BM:PDDTT Model of an organic,solar cell. These theoretical

Utility-based outcomes made easy: The number needed per QALY gained (NNQ). Observational cohort study from Southern Sweden of TNF blockade in inflammatory arthritis.

OBJECTIVE.: To introduce a novel, simple, utility based outcome measure, the Number Needed per Quality adjusted life year (QALY) gained (NNQ), and to apply it in clinical practice in anti-TNF treated patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and spondylarthritis (SpA). METHODS.: The NNQ is the number of patients one has to treat in order to gain 1 QALY. It is calculated a

Two-Year Survival Follow-Up of the Randomized, Double-Blind, Placebo-Controlled Phase II Study of Radium-223 Chloride in Patients With Castration-Resistant Prostate Cancer and Bone Metastases

In this 24-month follow-up of a phase II study in patients with castration-resistant prostate cancer (CRPC) and bone metastases, radium-223 (4 injections of 50 kBq/kg every 4 weeks [n = 33]) improved median overall survival vs. matching placebo (n = 31) (65.3 vs. 46.4 weeks, respectively; log-rank P = .056), with no long-term safety concerns. Data suggest that treatment of bone disease with radium

Magnet design for a low-emittance storage ring.

The MAX IV 3 GeV storage ring, currently under construction, pursues the goal of low electron beam emittance by using a multi-bend achromat magnet lattice, which is realised by having several consecutive magnet elements precision-machined out of a common solid iron block, 2.3-3.4 m long. With this magnet design solution, instead of having 1320 individual magnets, the MAX IV 3 GeV storage ring is b

Use of bacillus Calmette-Guérin in stage T1 bladder cancer: Long-term observation of a population-based cohort.

Abstract Objective. The aim of this study was to analyse the rate of use of bacillus Calmette-Guérin (BCG) at a population-based level, and the overall mortality and bladder cancer mortality due to stage T1 bladder cancer in a national, population-based register. Materials and methods. In total, 3758 patients with primary stage T1 bladder cancer, registered in the Swedish Bladder Cancer Register b
