Bone area is one measure of bone size that is easily derived from dual-energy X-ray absorptiometry (DXA) scans. In a GWA study of DXA bone area of the hip and lumbar spine (N ≥ 28,954), we find thirteen independent association signals at twelve loci that replicate in samples of European and East Asian descent (N = 13,608 – 21,277). Eight DX
The formation of a hybrid composite material consisted of polymer brushes and phenylboronic acid ligands on a macroporous cryogel is reported here for the first time for effective adsorption of glycoprotein and yeast cells. The surface area of the cryogel was increased by covalent immobilization of silica nanoparticles. Random copolymer brushes composed of N-isopropylacrylamide and glycidyl methac
Scientific Poster titled “Low-energy daylit dwellings in the dense city - Benchmarks, metrics and tools securing good daylighting, low energy use and user acceptance”, Velux Academic Forum, Berlin, 2 May 2017. This dissemination illustrates the research questions and key aspects of a PhD research project regarding daylight utilization in Swedish apartment blocks, which was initiated in February 20
Variable compression ratio (VCR)and variable valve timing (VVT)are two effective strategies to adjust the effective compression ratio, which is beneficial for controlling the combustion process of advanced combustion modes. In this study, systematic evaluation of the two strategies was conducted based on reactivity controlled compression ig
This work presented the working scheme developed and used in order to conduct multiple daylight simulations for distinct rooms in a wide range of apartment buildings within the urban grid. The objective was to generate 3D models of the rooms under study and their urban surroundings, and to obtain the corresponding illuminance files and geometry information in a time-efficient, automated manner. Th
We present new in-situ measurements of particle rotations and energy dissipation during compression of 3D packings of stiff, frictional particles. Two confined, uniaxial compression tests with different degrees of lateral confinement are discussed. X-ray computed tomography and 3D X-ray diffraction were combined to provide inter-particle forces, slip and roll distances, twist angles, and energy di
This work presented and optimization scheme for daylighting, heating and thermal comfort objectives in a highly insulated apartment, while varying different geometrical aspects of external windows (number, shape, size, position). To satisfy all objectives simultaneously, a large number of design iterations was evaluated by the use of the SPEA2 genetic algorithm as it is implemented on the Octopus
Renovating and improving the current building stock is a matter of both need and importance. In order to know if the implemented renovation measure has had an impact on the building as a system it is important to verify the impact through measurements. The aim of this project is to isolate the impact of a measure on the energy efficiency of a building as well as the indoor environmental quality. T
The Sommerodde-1 core from Bornholm, Denmark, provides a nearly continuous sedimentary archive from the Upper Ordovician through to the Wenlock Series (lower Silurian), as constrained by graptolite biostratigraphy. The cored mudstones represent a deep marine depositional setting in the foreland basin fringing Baltica and we present high-res
An expanded record (~14 m)of the Paleocene–Eocene Thermal Maximum (PETM), a transient period of extreme global warming that occurred ~56 million years ago, has been found based on calcareous nannofossil and foraminifera stratigraphy in the deep marine Río Gor section, Subbetic Zone, SE Spain. During the early Palaeogene the Subbetic Zone wa
Gamow-Teller β decay is forbidden if the number of nodes in the radial wave functions of the initial and final states is different. This Δn=0 requirement plays a major role in the β decay of heavy neutron-rich nuclei, affecting the nucleosynthesis through the increased half-lives of nuclei on the astrophysical r-process pathway below both Z=50 (for N>82) and Z=82 (for N>126). The level of forbidde
PURPOSE OF REVIEW: Impaired neurocognitive function is common in cardiac arrest survivors and the use of specific neurocognitive assessments are recommended in both clinical trials and daily practice. This review examines the most recent evidence to guide in the selection of neurocognitive outcome assessment tools after cardiac arrest. RECENT FINDINGS: Neurocognitive impairment after cardiac arres
PURPOSE OF REVIEW: Withdrawal of life-sustaining therapy due to a presumed poor neurological prognosis precedes most deaths in patients who have been resuscitated after an out-of-hospital cardiac arrest and are being treated in an ICU. Guidelines to support these critical decisions recommend a multimodal strategy based on advanced diagnostic methods. This review will discuss clinical experience wi
Background: Breakthroughs in the treatment of preterm birth approximately 40 years ago have enabled a generation of preterm survivors to now reach mid-adulthood. Understanding their health sequelae is essential for guiding their long-term care. We did a study to examine preterm birth in relation to mortality into mid-adulthood. Methods: A national cohort study was done of all 4 296 814 singleton l
We report magnetic properties and relative paleointensity (RPI) proxies from a suite of 10 conventional piston cores and Kasten cores from the SW Iberian Margin collected during cruise JC089 of the RSS James Cook in August 2013. Mean sedimentation rates are in the 10–20 cm/kyr range. Age models were acquired by correlation of Ca/Ti and Zr/Sr XRF core-scanning data to L* reflectance from the Cariac
This thesis is based on work done by the author on the development of laser wakefield accelerators.Wakefield acceleration in plasmas is a promising technique to provide the next generation of accelerating structures and particle beams. Plasmas can sustain electric fields that are many orders of magnitude stronger than those possible in conventional accelerators. Other benefits of wakefield acceler
Abstract Due to a lack of marine macrofossils in many sediment cores from the estuarine Baltic Sea, researchers are often forced to carry out 14C determinations on bulk sediment samples. However, ambiguity surrounding the carbon source pathways that contribute to bulk sediment formation introduces a large uncertainty into 14C geochronologies based on such samples, and such uncertainty may not have
There is a variety of different cosmogenicradionuclide-based reconstructions of solar activity varia-tions for the past. Especially the longer-term changes andthe absolute levels of past solar activity are uncertain as it isillustrated by the differences between these reconstructions.On the one hand there are differences between10Be and14Crecords that are commonly used as proxies for
