Context. With the goal to accurately map about a billion of the Milky Way stars, the astrometric satellite Gaia was launched in December 2013. Its high precision and sensitivity will lead to better understanding of the Galactic structure and evolution. Also, it will be possible to probe the matter distribution in the Galaxy. Aims. To study how well the Galactic matter distribution can be determin
Warehouse management is the science of optimizing warehouse activity with the intention of reducing inventory holding costs and increasing material throughput. A warehouse management system (WMS) is an IT system used to support warehouse processes and ensure a smooth ow of material. The main objectives of the WMS are to keep track of inventory levels and distribute tasks to warehouse sta. The syst
The reactivity of catalytic surfaces is often dominated by very reactive low-coordinated atoms such as step-edge sites1-11. However, very little knowledge exists concerning the influence of step edges on the selectivity in reactions involving multiple reaction pathways. Such detailed information could be very valuable in rational design of new catalysts with improved selectivity. Here we show, fro
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Hyaluronan (hyaluronsyra) är en högmolekylär polysackarid som förekommer i all biologisk vävnad i olika koncentrationer, med särskilt höga nivåer i bindväv. Den kan bildas av de flesta celltyper. På molekylär nivå föreligger den i form av ett nystan, har förmågan att binda stora mängder vatten, och har en uttalad pseudoplasticitet. HyaHyaluronan has been found in the eye in varying amounts and at different sites. It is involved in physiological and pathological processes, though many aspects of its bio-logi-cal functions are still unclear. We have studied the role of iris tissue in hyal-uro-nan production in the anterior segment of the eye, and its changes after trauma. After peripheral iridectomy or argon laser treatment, the
PCB concentrations were studied in different soils to determine the spatial variation over a region of approximately 11000 km(2). PCB congener pattern was used to illustrate the spatial differences, as shown by principal component analysis (PCA). The relationship to different soil parameters was studied. PCB concentrations in soil showed a large variation between sampling-areas with median concent
Streptococcus pyogenes, the most significant streptococcal species in clinical medicine, expresses surface proteins with affinity for several human plasma proteins. Here we report that kininogens, the precursors to the vasoactive kinins, bind to the surface of S. pyogenes. M protein, a surface molecule and a major virulence factor-in these bacteria, occurs in > 80 different serotypes. Among 49 str
Many proteins rely on rare structural fluctuations for their function, whereby solvent and other small molecules gain transient access to internal cavities. In magnetic relaxation dispersion (MRD) experiments, water molecules buried in such cavities are used as intrinsic probes of the intermittent protein motions that govern their exchange with external solvent. While this has allowed a detailed c
The silicon isotope composition of biogenic silica (δ30SiBSi) in the ocean is a function of the δ30Si of the available dissolved Si (DSi; H2SiO4), the degree of utilisation of the available DSi, and, for some organisms, the concentration of DSi. This makes δ30SiBSi in sediment archives a promising proxy for past DSi concentrations and utilisation. At steady-state, mean δ30SiBSi must equal a weight
Context. Recent spectroscopic surveys have begun to explore the Galactic disk system on the basis of large data samples, with spatial distributions sampling regions well outside the solar neighborhood. In this way, they provide valuable information for testing spatial and temporal variations of disk structure kinematics and chemical evolution. Aims. The main purposes of this study are to demonstra
BACKGROUND AND PURPOSE: A new concept to increase return to work for patients listed as sick with chronic musculoskeletal pain has been used at a rehabilitation centre in Luleå, Sweden. The programme includes work for three days a week and intensive rehabilitation for two days a week, for 12 weeks, as a combination of 'on the job' training and rehabilitation after a period off work sick. The rehab
Though long admired for its Pharaonic stelae, shrines, and rock-cut temple, the grand ancient site of Gebel el Silsila remains fairly unknown withinmainstream archaeology. A general idea is that the site operated merely as a sandstone quarry, but few are aware of its rich archaeology thatincorporates evidence of millennia of human activity and cultural features that meet seven of UNESCO’s ten outs
In recent decades, there has been significant attention on the decline in insect populations, including moths and hover flies. To tackle this issue, innovative methods such as entomological LiDAR technology have revolutionized the remote identification of free-flying insects. The distinct spectral reflection from moth and hover fly wings enables precise differentiation between species and sexes. W
Japanese knotweed (Reynoutria japonica) is a problematic plant species that causes a lot of damage on anthropological constructions as well as ecosystems throughout Europe. Several attempts have been made to control this species, such as glyphosates, cutting/mowing, covering with geoweave and digging, so far with varying degrees of success. In recent times different techniques of heat treatment ha
Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. Electrification of vehicles is an important part of this shift. As a r
Bakgrund: Obesitas och psykisk ohälsa tillhör de största globala hälsoutmaningarna i modern tid och har under de senaste decennierna varit ett växande problem. Människor har fått en mer stillasittande livsstil och större tillgång på kaloririk föda. Faktorerna som påverkar prevalensen är många men att det behöver ske en förändring är säkert. Syfte och frågeställningar: Syftet var att kartlägga BMI,
The demand for high data rates in a wireless communication system has experienced a remarkable growth over the last years. This demand is continually increasing with the growing number of wirelessly connected devices. Thus, there is a continuing hunt for increasing the data transmission rate in wireless communication systems. To increase the data rate, the modern wireless communication system cann
