Precambrian inliers of the Anti-Atlas belt in the southern part of Morocco contain numerous dolerite dyke and sill swarms which were previously poorly dated. Four dykes and two sills dated by the U-Pb TIMS method on baddeleyite and zircon provide the first steps toward a magmatic 'barcode' for the West African Craton (WAC) and constraints on the timing of breakup of the WAC from Precambrian superc
We investigated amorphous Si (ASi) in a boreal wetland in northern Sweden. We found enormous stocks of ASi in the upper soil layers (up to 11% of dry weight), in the form of diatom frustules and plant ASi. A consistent exponential decrease in ASi concentrations was observed with increasing depth in the soil profile. An inverse modeling approach shows that vegetation takes up a substantial part of
This study aims to compare and validate two soil-vegetation-atmosphere-transfer (SVAT) schemes: TERRA-ML and the Community Land Model (CLM). Both SVAT schemes are run in standalone mode (decoupled from an atmospheric model) and forced with meteorological in-situ measurements obtained at several tropical African sites. Model performance is quantified by comparing simulated sensible and latent heat
Folding of the ribosomal protein S6 is a malleable process controlled by two competing, and partly overlapping, folding nuclei. Together, these nuclei extend over most of the S6 structure, except the edge strand beta 2, which is consistently missing in the folding transition states; despite being part of the S6 four-stranded sheet, beta 2 seems not to be part of the cooperative unit of the protein
The proportion dominance effect (PDE) refers to a higher motivation to help when the victims are part of a small (you can help 56 out of 60) rather than a large (you can help 56 out of 560) reference group. In two studies using different experimental paradigms, we investigated possible mediators of the PDE. Study 1 (N = 168) was conducted in three separate steps in order to test each link of the m
Glypicans are multifunctional cell surface proteoglycans involved in several important cellular signalling pathways. Glypican-1 (Gpc1) is the predominant heparan sulphate (HS) proteoglycan in the developing and adult human brain. The two N-linked glycans and the C-terminal domain that attaches the core protein to the cell membrane are not resolved in the Gpc1 crystal structure. Therefore we have s
In Elder-Vass’s response to my (2014) it is maintained: (1) that a social object is not identical with but is merely composed of its suitably interrelated parts; (2) that a social object is necessarily indistinguishable in terms of its causal capacities from its interrelated parts; and (3) that ontological individualism lacks an adequate ontological justification (Elder-Vass forthcoming). In this
This article gives an account of an eye-tracking experiment carried out during a workshop at Lund University, where the overall question was, "how does film music affect meaning?". The pilot experiment was conducted on an exploratory basis, and in this article, the tentative results and possible usefulness of laboratory experiments are discussed.
This study tested the prediction that dissociative tendencies modulate the impact of a hypnotic induction on cognitive control in different subtypes of highly suggestible individuals. Low suggestible (LS), low dissociative highly suggestible (LDHS), and high dissociative highly suggestible (HDHS) participants completed the Stroop color-naming task in control and hypnosis conditions. The magnitude
The island Surtsey was formed in a volcanic eruption south of Iceland in 1963–1967 and has since then been protected and monitored by scientists. The first two moss species were found on Surtsey as early as 1967 and several new bryophyte species were discovered every year until 1973 when regular sampling ended. Systematic bryophyte inventories in a grid of 100 m × 100 m quadrats were made in 1971
Welfare state research tends to assume strong and enduring public support for welfare state institutions. We challenge this assumption and show that in times of economic crisis, positive welfare state attitudes are confronted with conflicting preferences for improvement of labour market performance. We argue that such movements in public opinion have led to issue competition among major political
We describe a family phi(lambda) of dynamical systems on the unit interval which preserve Bernoulli convolutions. We show that if there are parameter ranges for which these systems are piecewise convex, then the corresponding Bernoulli convolution will be absolutely continuous with bounded density. We study the systems phi(lambda) and give some numerical evidence to suggest values of lambda for wh
An earlier study revealed that Mainland Chinese women experienced a relatively low health-related quality of life during the first 3 months after being diagnosed with cervical cancer. This merited conducting a qualitative study to explore their experiences during this period.
Proton-transfer dynamics plays a critical role in many biochemical processes, such as proton pumping across membranes and enzyme catalysis. The large majority of enzymes utilize acid-base catalysis and proton-transfer mechanisms, where the rates of proton transfer can be rate limiting for the overall reaction. However, measurement of proton-exchange kinetics for individual side-chain carboxyl grou
OBJECTIVES: Alpha1-antitrypsin deficiency (AATD) is a common genetic cause of chronic liver disease. According to retrospective studies, up to 25% of those with homozygous ZZ (Glu 342 to Lys) AATD suffer from liver cirrhosis and/or liver cancer in late adulthood. We hypothesized that the plasma markers for liver fibrosis, necrosis, and apoptosis may identify AATD individuals at higher risk for liv
DNA in the human Herpes simplex virus type 1 (HSV-1) capsid is packaged to a tight density. This leads to tens of atmospheres of internal pressure responsible for the delivery of the herpes genome into the cell nucleus. In this study we show that, despite its liquid crystalline state inside the capsid, the DNA is fluid-like, which facilitates its ejection into the cell nucleus during infection. We
The base (BOP) and the top (TOP) of the world income pyramid represent the poor people and the people from developed countries, respectively. About two-fifths of the world population can be categorized as poor. Poverty is a trap because children born to poor parents are likely to grow up to be poor adults. In recent years, a poverty reduction approach that combines business development with povert
A sediment record from a small lake in the north-eastern part of the Kamchatka Peninsula has been investigated in a multi-proxy study to gain knowledge of Holocene climatic and environmental change. Pollen, diatoms, chironomids and selected geochemical parameters were analysed and the sediment record was dated with radiocarbon. The study shows Holocene changes in the terrestrial vegetation as well
Previous fire accidents have shown that fires in underground transportation systems, e.g., tunnels and underground stations, can cause many fatalities. It is therefore important in fire safety design to give adequate consideration to all aspects related to evacuation. The main purpose of this paper is to provide guidance to engineers involved in the design of underground transportation systems, an
