Cell replacement therapy of neurodegenerative disorders aims to substitute the degenerating cells with new functional neurons. Clinical trails with patients suffering from Parkinson’s or Huntington’s disease have generated proof-of-principle results that neural precursors taken from the developing human brain can survive upon grafting to the diseased brain and provide long-lasting symptomatic reli
A search for long-lived particles is performed using a data sample of 4.7 fb(-1) from proton-proton collisions at a centre-of-mass energy. root s = 7 TeV collected by the ATLAS detector at the LHC. No excess is observed above the estimated background and lower limits, at 95% confidence level, are set on the mass of the long-lived particles in different scenarios, based on their possible interactio
This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of
Background: A trial fibrillation (AF) is a common problem in pacemaker patients. We conducted a prospective observational study in patients paced for bradycardia with associated paroxysmal or persistent AF, to determine whether P-wave duration may stratify patients at higher risk for AF recurrences and AF-related hospitalizations. The patients were evaluated for the prevalence, cause, and predicto
A cheap value-added product, the protein fraction of barley spent grains is proposed as a source of a potential and economical cultivation medium. We showed that medium composed of protein fraction extract allows the isolation of actinobacteria, especially Streptomyces, from soil samples, and enhances the sporulation. It was used for the screening and production of the biologically active substanc
The release of two compositionally different solutes from a composite gel composed of two different populations of microgel particles embedded in a single bulk gel matrix is described, showing the potential of the "plum-pudding gel" as a multifunctional platform for controlled surface release. One hydrophobic solute (pyrene) and one hydrophobic and charged solute (rhodamine 123) were chosen as the
OBJECTIVES: The purpose of this study was to estimate retrospectively the costs of health care resources used in the Malmö Preventive Project, Sweden and estimate the costs of in-patient care that were avoided because of early intervention. SETTING AND SUBJECTS: A large-scale community intervention programme was conducted from 1974 to 1992 in Malmö, Sweden with the aim of reducing morbidity and mo
Indolyl substituted pyranyl- and cyclohexenyl molybdenum complexes were synthesised through stereoselective nucleophilic addition of indoles to the corresponding cationic 2H-pyran or cyclohexadiene molybdenum complex. Decomplexation of an allylic molybdneum complex by treatment with iodine gave 1-(4-iodo-2-cyclohexenyl)-1H-indole-3-carbonitrile in high regio-selectivity. A new method for preparati
When biomass is used to produce fuels and green products by thermochemical conversion, the ability to handle or remove the fine particle phase in the product gas is crucial. The product gas from biomass gasification contains relatively volatile organic compounds (“tar”) condensed on nonvolatile cores of, for example, aggregated soot particles and char. The problems are, for example, that particles
This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic oxidation catalyst mounted after a heavy duty diesel engine in a rig. The conversion of hydrocarbons is predicted
Popular Abstract in English Nowadays, cutting-edge technologies require devices to be small, ultrafast, and operational in a wide range of regimes. To fulfill these requirements we need to go beyond the traditional materials, i.e. to solids with novel, unconventional and tailorable properties. Great progress in this direction is conjectured to stem from materials in which the effect of inter-partiCutting-edge technology needs small, ultrafast devices, operational in a wide range of regimes. This calls for solids with novel, unconventional and tailorable properties. Great progress is expected from materials in which electron-electron and electron-phonon correlations strongly affect the dynamics ( i.e. "unforeseen" useful properties are expected to be most likely found in systems with comple
In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategie
This research paper focuses on historical, arithmetic equity market risk premium in emerging and frontier markets. Equity market risk premium, as we know it today, has been easily estimated in developed markets; whereas, emerging and frontier markets often require different approaches to determine an appropriate equity market risk premium. I make use of a variety of methods, including volatility a
Climate change is a real challenge with global impacts in scope. The negative impacts of climate change are being experienced globally through raising temperatures, rising sea levels, melting ice and glaciers, extended drought and floods, soil erosion among others. The most vulnerable and affected by climate change are the developing countries that lack adaptive capacity to the impacts of climate
Liksom en trädstam uppvisar årsringar som kan användas för att beräkna dess ålder, bildas också tillväxtringar i tänderna hos många djur, även hos dem som regelbundet byter tanduppsättning. Detta fenomen noterades av paleontologen Richard Owen redan i mitten av 1800-talet, men det är först de senaste decennierna som forskningen inom tandersättningscykler hos utdöda djur har tagit fart. Så kalladeThe dentine of teeth from five genera of mosasaurs [i.e., Clidastes, Halisaurus, Dollosaurus (Prognathodon),cf. Platecarpus, and Tylosaurus] and a Mesozoic crocodylian (Aigialosuchus) from the Campanian of the Kristianstad Basin, southernmost Sweden, displays two types of incremental growth lines; i.e., von Ebner’s and, for the first time in extinct animals, Andresen’s lines. These lines are homol
