Time Scales of Conformational Gating in a Lipid-Binding Protein
Lipid-binding proteins Sequester amphiphilic molecules in a large internal : cavity occupied by similar to 30 water molecules, some of which are displaced by the ligand. The role; of these internal water molecules in lipid binding and release is not understood. We use magnetic relaxation dispersion (MRD) to directly monitor internal-water dynamics in apo and palmitate-bound rat intestinal fatty ac
Mothers' representations of caregiving and their adult children's representations of attachment: Intergenerational concordance and relations to beliefs about mothering.
Mothers (N= 35) and their adult children completed questionnaires and were interviewed in order to examine relationships between mothers' caregiving representations and their adult children's attachment representations, and relationships between attachment/caregiving representations and beliefs about mothering. Mothers' and their children's accounts of and present thinking about their past relatio
Investigation on elemental mercury oxidation mechanism by non-thermal plasma treatment
Converting elemental mercury into divalent compound is one of the most important steps for mercury abatement from coal fired flue gas. The oxidation of elemental mercury was investigated in this paper using dielectric barrier discharge (DBD) non-thermal plasma (NTP) technology at room temperature. Effects of different flue gas components like oxygen, moisture, HCl, NO and SO2 were investigated. Re
Utilization of prey-rich patches leads to reproductive advantages for clustered individuals of a web-building spider
The ideal free distribution (IFD) model predicts that consumers match the distribution of resources across habitat patches and that this association should lead to equal individual fitness among individuals in a population. Here we studied to what extent predators utilize different prey groups and if the resulting spatial patterns relate to the reproductive success of individuals in a population o
Studying associations between variants in TRAF1-C5 and TNFAIP3-OLIG3 and the progression of joint destruction in rheumatoid arthritis in multiple cohorts
On the reliability of powder diffraction Line Profile Analysis of plastically deformed nanocrystalline systems.
An iron-molybdenum alloy powder was extensively deformed by high energy milling, so to refine the bcc iron domain size to nanometer scale (~10 nm) and introduce a strong inhomogeneous strain. Both features contribute to comparable degree to the diffraction peak profile broadening, so that size and strain contributions can be easily separated by exploiting their different dependence on the diffract
Towards Quantitative Optical Cross Sections in Entomological Laser Radar - Potential of Temporal and Spherical Parameterizations for Identifying Atmospheric Fauna.
In recent years, the field of remote sensing of birds and insects in the atmosphere (the aerial fauna) has advanced considerably, and modern electro-optic methods now allow the assessment of the abundance and fluxes of pests and beneficials on a landscape scale. These techniques have the potential to significantly increase our understanding of, and ability to quantify and manage, the ecological en
A Correlation Analysis of the Roles of Soot Formation and Oxidation in a Heavy-Duty Diesel Engine
Emissions and in-cylinder pressure traces are used to compare the relative importance of soot formation and soot oxidation in a heavy-duty diesel engine. The equivalence ratio at the lift-off length is estimated with an empirical correlation and an idealized model of diesel spray. No correlation is found between the equivalence ratio at lift-off and the soot emissions. This confirms that trends in
Search for a light charged Higgs boson in the decay channel H+ -> c(s)over-bar in t(t)over-bar events using pp collisions at root s=7 TeV with the ATLAS detector
A search for a charged Higgs boson (H+) in t (t) over bar decays is presented, where one of the top quarks decays via t -> H(+)b, followed by H+ -> two jets (c (s) over bar). The other top quark decays to Wb, where the W boson then decays into a lepton (e/mu) and a neutrino. The data were recorded in pp collisions at root s = 7 TeV by the ATLAS detector at the LHC in 2011, and correspond to an int
Mechanistic studies on the role of extracellular vesicles in the tumor microenvironment
Popular Abstract in Swedish Cancerceller är celler som på grund av mutationer, felaktigheter i cellernas DNA, har erhållit förmågan att dela sig ohämmat. Celler behöver tillgång till syre och näring för att överleva, vilket levereras via kroppens blodkärl. Den snabba tillväxten av tumörvävnad leder dock till att befintlig blodtillförsel inte räcker till och delar av tumörerna drabbas därför av syrThe transition from normal into malignant cells with acquired uncontrolled growth is a process where cancer cells viciously develop adaptive strategies to overcome microenvironmental and metabolic stress. Hypoxia, or deficient oxygen supply, is a common feature of the expanding tumor which alters cell metabolism and consecutively causes lowered intracellular pH. To alleviate hypoxic and acidotic s
Laminar-flow Liquid-to-air Heat Exchangers - Energy-efficient Display Cabinet Applications
Popular Abstract in Swedish Resultaten som presenteras i denna doktorsavhandling visar att det går att spara stora mängder energi genom att använda samma typ av värmeväxlare, som normalt används i bilar och lastbilar, i livsmedelsbutikernas kyldiskar. För att hålla maten kall när den ligger ute i butiken cirkuleras en kyld luftström runt i kyldiskarna. Denna kyls i en så kallad värmeväxlare som Provisions are stored and displayed in supermarkets and grocery stores, at a temperature lower than the ambient, in display cabinets, which are responsible for a significant amount of the energy use in this sector. During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. This resulted in many refrigeration systems being converted to syste
LED-induced fluorescence system for tea classification and quality assessment
A fluorescence system was developed by using several light emitting diodes (LEDs) with different wavelengths as excitation light sources. The fluorescence sensor head consists of multi LED light sources and a multimode fiber for fluorescence collection, where the LEDs and the corresponding filters can be easily chosen to get appropriate excitation wavelengths for different applications. By analyzi
Effect of geometrical contraction on vortex breakdown of swirling turbulent flow in a model combustor
Large Eddy Simulation (LES) studies of isothermal and incompressible turbulent swirling flows in a model gas turbine combustion chamber geometry have been carried out. The focus is on the effect of outlet geometry contraction on the vortex breakdown structure and the precessing vortex core in the chamber. Nine different outlet geometries with different contraction ratio C-r are considered. The res
Coordination-Mix: The Hidden Face of STI Policy
This paper sheds light on the policy coordination concept and explores its implications for science, technology, and innovation (STI) policies at the regional level. In particular it analyzes whether systemic and complex STI policies entail a larger and more complex need for coordination. We contribute to the literature by developing a conceptual framework that brings together insights from instit

Gluco-incretins regulate Beta-cell glucose competence by epigenetic silencing of fxyd3 expression.
Gluco-incretin hormones increase the glucose competence of pancreatic beta-cells by incompletely characterized mechanisms.
Approximate boundary conditions for thin structures
In wave propagation problems thin structures are often replaced by boundaries of zero thickness, in order to reduce the numerical mesh. The reduction of thickness has to be incorporated in the approximate boundary condition applied to the interface. This paper presents a modification of an approximate boundary condition originally introduced by Mitzner. The modified Mitzner condition can be applie
Burchnall-Chaundy Theory for Ore Extensions
We begin by reviewing a classical result on the algebraic dependence of commuting elements in the Weyl algebra. We proceed by describing generalizations of this result to various classes of Ore extensions, including both results that are already known and one new result.
Major histocompatibility complex class II compatibility, but not class I, predicts mate choice in a bird with highly developed olfaction.
Mate choice for major histocompatibility complex (MHC) compatibility has been found in several taxa, although rarely in birds. MHC is a crucial component in adaptive immunity and by choosing an MHC-dissimilar partner, heterozygosity and potentially broad pathogen resistance is maximized in the offspring. The MHC genotype influences odour cues and preferences in mammals and fish and hence olfactory
