A precise U–Pb baddeleyite age (2251 ± 4 Ma) has been obtained for an ENE-trending dyke exposed near the Chhura region of the Bastar craton, and additional dykes of similar trend are also reported from other parts of the northern Bastar craton such as in the Dongergarh and Pakhanjore areas. We propose a new widespread ENE-trending ca. 2.25 Ga Chhura mafic dyke swarm in the Bastar craton, which rep

The impact of longitudinal vibration on cross-bridge attachments between myofilaments was investigated in single fibres and intact muscle. Sinusoidal length vibration (frequency 50 Hz, amplitude 5% of fibre length) reduced active force by 40% when fibres were activated by elevation of [Ca2+], but did not alter the force when fibres were in rigor state. When vibrated for 30 min in rigor at pH 5.5 a

Sediments are a key sink for phosphorus (P) in coastal systems. This allows coastal areas to act as a filter for P that is transported from land to sea. Recent work suggests that vivianite-type ferrous iron (Fe(II))-P minerals may be more important as a sink for P in coastal sediments than previously thought. Here, we investigate the occurrence of such vivianite-type minerals in sediments of three

“Wet” eldercare facilities for people who age with long-term substance use problems and complex needs exist in several countries. Residents are accepted as active users of alcohol and drugs, and while the media has presented the permissive policies of the facilities in a positive light, others have described these policies as harmful. The aim of this article is to analyze residents' and staff memb

The general outline of the long-term history of cereal cultivation in southern Sweden is relatively well known from published compilations of archaeobotanical data (Hjelmqvist 1955; Engelmark 1992; Gustafsson 1998; Viklund 1998; Grabowski 2011). These compilations show emmer (Triticum dicoccum) and naked barley (Hordeum vulgare var. nudum) as the principal crops of the Neolithic and the Early Bron

Functional data analysis is typically performed in two steps: first, functionally representing discrete observations, and then applying functional methods, such as the functional principal component analysis, to the so-represented data. While the initial choice of a functional representation may have a significant impact on the second phase of the analysis, this issue has not gained much attention

Drug use disorders (DUD) are associated with psychiatric illness and increased risks of suicide. We examined health care utilization prior to suicide in adults with DUD, which may reveal opportunities to prevent suicide in this high-risk population. A national cohort study was conducted of all 6,947,191 adults in Sweden, including 166,682 (2.4%) with DUD, who were followed up for suicide during 20

Electrochemical removal of nitrogen oxides (NOx) by solid electrolyte cells (SECs) is a promising technology due to no required reductant. Herein, a series of La0.8Sr0.2Mn1−xNixO3 (0 ≤ x ≤ 0.5) perovskites were first synthesized and utilized as the electrode materials of SECs. The role of Ni substitution in electrode performance and NOx reduction mechanism were revealed by various experimental cha

When the famous bishop of Lund, Peder Winstrup, died in 1679 he was laid to rest in a family crypt in Lund Cathedral alongside his wife. Following a restoration of the Cathedral in the late 19th century, Peder Winstrup's coffin was moved to the crypt, as the family grave was dismantled. In 2012, a decision was made to move his remains to a different location presenting scientists with an opportuni

Highly crystalline K2GeF6 micropowders were prepared by co-precipitation in the hydrofluoric acid-water-alcohol solution and studied by means of the cathodoluminescence and time-resolved luminescence spectroscopy under synchrotron radiation excitation at 7 K. The nature of various intrinsic emissions was revealed. The luminescence band at 510 nm detected under excitation by photons with the energy

Background: The predictive effects of change patterns of sleep problems on mental health after a long-term disaster remain poorly known. We examined the change patterns of sleep problems after the Wenchuan earthquake, and tested whether specific sleep-related change patterns could predict mental health problems (posttraumatic stress disorder [PTSD], anxiety, and depression) in the 10 years after W

Although being promoted as the most eco-friendly form of transportation, the shipping sector currently accounts for around 3 % of global greenhouse gas (GHG) emissions, however, with increasing global trade emissions are expected to increase. Even if energy efficiency gains have been accomplished, the majority of the global fleet continue to run on fossil fuels and the total emissions from ships a

IntroductionPost-operative infections obtained from open-wound surgeries constitute an unnecessary load on both healthcare and affected patients. It is well established that increased air cleanliness reduces the number of post-operative infections. Therefore, the ventilation system is important in order to reduce the number of infectious particles in the air during surgery. Ventilation with high a

Theoretical investigations of Cross Laminated Timber (CLT) at in-plane shear loading conditions are presented with focus on shear failure mode III, relating to shear stresses acting in the crossing areas between orthogonally bonded laminations of different layers. Failure criteria for structural design, test configurations and material parameters are discussed. Full 3D finite element (FE) analyses
