Background 3-Hydroxypropionic acid (3HP) and acrylic acid (AA) are industrially important platform- and secondary chemical, respectively. Their production from renewable resources by environment-friendly processes is desirable. In the present study, both chemicals were almost quantitatively produced from biodiesel-derived glycerol by an integrated process involving microbial and chemical catalysis

A new genus, Catenarina (Teloschistaceae, Ascomycota), with three species is described from the Southern Hemisphere, supported by molecular data. All species contain the secondary metabolite 7-chlorocatenarin, previously unknown in lichens. Catenarinadesolata is a non-littoral, lichenicolous species found on volcanic and soft sedimentary rock at 190-300 m in and near steppes in southernmost Chile

Windows in a package is a common way to promote the product. The possibility to predict the collapse load for these types of cartonboard packages is considered. It is shown that reliable estimates of the collapse loads can be obtained by a very simple approach. This approach is a straightforward generalization of the proposal by Ristinmaa et al. (2012): for a side that contains a window, one simpl

Critical evaluation of the World Missionary Conference, Edinburgh 1910, from the perspective of later 20th century developments in Christian mission and ecumenism, with special attention to the global South and postcolonial analysis.

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 (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

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

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

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

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

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

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

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

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

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

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
