Reconstructions of the Holocene geomagnetic field and how it varies on millennial timescales are important for understanding processes in the core but may also be used to study long-term solar-terrestrial relationships and as relative dating tools for geological and archaeological archives. Here, we present a new family of spherical harmonic geomagnetic field models spanning the past 9000 yr based

The latent heat flux (LE) between the terrestrial biosphere and atmosphere is a major driver of the global hydrological cycle. In this study, we evaluated LE simulations by 45 general circulation models (GCMs) in the Coupled Model Intercomparison Project Phase 5 (CMIP5) by a comparison with eddy covariance (EC) observations from 240 globally distributed sites from 2000 to 2009. In addition, we imp

Background In recent studies of primary percutaneous coronary intervention (PCI), bivalirudin compared with heparin has been associated with increased risk of stent thrombosis (ST). Our aim was to describe incidence and outcome of definite, early ST in a large contemporary primary PCI population divided in antithrombotic therapy subgroups. Methods and Results A prospective, observational cohort st

The turnover in vivo of proteoglycans of guinea pig costal cartilage was investigated using Na2 35SO4 as precursor. Proteoglycans were extracted with guanidine · HCl, at both low and high ionic strength, and purified and fractionated by ultracentrifugation in CsCl gradients under associative and dissociative conditions. The results suggest that the sulfate is incorporated into macromolecules of at

The aim of this paper was to examine how useable and inclusive the city is from the perspective of older bicyclists. Methods used were quantitative questionnaires and qualitative focus group interviews. Participants were people aged 65 years or older. The results showed that respondents were fairly satisfied with the transport infrastructure design. However, other road users seemed to complicate c

Purpose – The purpose of this paper is to examine the influence that family factors have on an individual’s intention to be self-employed. Design/methodology/approach – The authors selected, from Swedish national registers, all full siblings born between 1945 and 1960 and their biological children, who were born before 1985. The authors created one family database consisting of male individuals (n

The behaviour of people in the first stage of an evacuation can have a significant impact on the time required to reach a safe place. This behaviour is known in literature as pre-evacuation behaviour and it has been studied for many different evacuating scenarios. Despite the large number of studies, the representation of this behaviour is often oversimplified in most of the existing evacuation mo

This paper highlights three important problems characterizing much of current leadership studies: the hegemonic ambiguity problem, the idyllic problem, and the methodological problem(s). I suggest three broad routes forward – taking the concept, the ideological aspects, and the epistemic challenges more seriously - which in various ways address, and in best case mitigate, the three problems. Recog

Pretreatments are crucial to achieve efficient conversion of lignocellulosic biomass to soluble sugars. In this light, switchgrass was subjected to 13 pretreatments including steam explosion alone (195 °C for 5, 10 and 15 min) and after impregnation with the following catalysts: Ca(OH)2 at low (0.4%) and high (0.7%) concentration; Ca(OH)2 at high concentration and higher temperature (205 °C for 5,
