The Palaeoproterozoic (1.90 - 1.60 Ga) crust of central Fennoscandia was intruded repeatedly by dolerite dikes and sills during the Neo- and Mesoproterozoic eons. We report 17 new baddeleyite U - Pb dates comprising six generations of dolerites ( in Ma): Blekinge-Dalarna dolerites 946 - 978 Protogine Zone dolerites 1,215 - 1,221 Central Scandinavian Dolerite Group 1,264 - 1,271 Tuna dikes and age
Background: Caloramator celer is a strict anaerobic, alkalitolerant, thermophilic bacterium capable of converting glucose to hydrogen (H2), carbon dioxide, acetate, ethanol and formate by a mixed acid fermentation. Depending on the growth conditions C. celer can produce H2 at high yields. For a biotechnological exploitation of this bacterium for H2 production it is crucial to understand the factor
Ectomycorrhizal fungi are known to vary in host range. Some fungi can enter into symbiosis with multiple plant species, while others have restricted host ranges. The aim of this study was to examine variation in host specificity among strains from the basidiomycete Paxillus involutus s. lat. Recent studies have shown that this fungus consists of at least four genetically isolated lineages, phyloge
A new type of treatment planning system called SHAREPLAN has been studied, which enables the transfer of treatment plans generated for helical tomotherapy delivery to plans that can be delivered on C-arm linacs. The purpose is to ensure continuous patient treatment during periods of unscheduled downtime for the TomoTherapy unit, particularly in clinics without a backup unit. The purpose of this wo
Alcohol consumption contributes to many negative health consequences and is a risk factor for death. Some previous studies however suggest a J-shaped relationship between the level of alcohol consumption and all-cause mortality. These findings have in part been suggested to be due to confounders. The aim of our study was to analyze the relationship between self-reported alcohol intake and all-caus
The most serious risk connected with transplantations besides infection is graft rejection. Organ transplant recipients (OTRs) perceive graft rejection as a stress factor and a threat. The primary aim of the present study was to examine types of coping used to handle the threat of the risk of graft rejection among OTRs and to investigate relations between coping and perceived threat as well as Hea
The airflow in the air gap behind the façade panel has shown to be of importance when risks of moisture and mould damages in wood frame walls are calculated. This study demonstrates the importance of a properly applied outdoor air flow in the air gap behind the façade panel when temperature and moisture conditions are calculated. The paper present and compare how variations in airflow in the air g
Presented to 42 schizophrenic patients and 19 normals, by means of a percept-genetic technique, two motifs of mother and infant in close interaction (feeding and nursing) . The motifs were tagged, by subliminal presentation, with aggressive resp. "healing" sentences, in a balanced design. No effects of this tagging were discernible. A cluster-analysis (Ward s method) of the material yielded 4 fair
Product gas obtained through biomass gasification can be upgraded to hydrogen-rich synthesis gas. The synthesis gas can be further converted to liquid or gaseous fuels. However, the raw product gas contains both gas- and particle-phase impurities that can negatively affect both catalysts and hot-gas filters used for upgrading and cleaning. The present study aimed to characterize, both physically a
GOALS:: To compare the clinical outcomes of gastroesophageal reflux disease (GERD) patients treated with an implemented new structured pathway (NSP) or according to existing local clinical practices [old clinical pathway (OCP)]. BACKGROUND:: GERD is a major challenge at the primary care level. STUDY:: Primary care centers (n=24) were cluster randomized to handle patients suffering from symptoms su
Contagious yawning is a well-documented phenomenon in humans and has recently attracted much attention from developmental and comparative sciences. The function, development and underlying mechanisms of the phenomenon, however, remain largely unclear. Contagious yawning has been demonstrated in dogs and several non-human primate species, and theoretically and empirically associated with empathy in
In-situ wide-angle X-ray scattering (WAXS) measurements have been conducted on atmosphericpressure fuel-rich premixed freely propagating ethylene/oxygen flames with argon and nitrogen dilution. In this work, a novel analysis methodology able to provide quantitative information on soot/carbon particle species and concentrations was tested under heavy sooting conditions. The particle composition and
Reactions in aqueous solution under hydrothermal conditions between (+/-)-2,3-dimethylsuccinic acid and lanthanide chlorides lead to two different isostructural types with chemical formulas [Ln(2)(C6H8O4)(3)(H2O)(2)] Ln(III) = Pr-Eu (except Pm) (Type I, compounds 1-4) and [Ln(2)(C6H8O4)(3)] Ln(III) = Tb-Yb (except Tm) (Type II, compounds 5-9). The crystal structure has been solved for the Pr (1)-,
Previous genome-wide association (GWA) studies have identified SNPs associated with areal bone mineral density (aBMD). However, this measure is influenced by several different skeletal parameters, such as periosteal expansion, cortical bone mineral density (BMDC) cortical thickness, trabecular number, and trabecular thickness, which may be under distinct biological and genetic control. We have car
The composite intrusions of Drumadoon and An Cumhann crop out on the SE coast of the Isle of Arran, Scotland and form part of the larger British and Irish Palaeogene Igneous Province, a subset of the North Atlantic Igneous Province. The intrusions (shallow-level dykes and sills) comprise a central quartz-feldspar-phyric rhyolite flanked by xenocryst-bearing basaltic andesite, with an intermediate
The autumn gum moth, Mnesampela privata (Guenee) (Lepidoptera: Geometridae), is native to Australia and can be a pest of plantation eucalypts. Field-collected and laboratory-reared female autumn gum moths were dissected to remove glands likely to contain components of the sex pheromone. Using gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC-MS), three compounds were id
Treatment of met-myoglobin (Fe-III) with H2O2 gives rise to ferryl myoglobin, which is closely related to compound II in peroxidases. Experimental studies have given conflicting results for this species. In particular, crystallographic and extended x-ray absorption fine-structure data have shown either a short (similar to170 pm) or a longer (similar to190 pm) Fe-O bond, indicating either a double
Objectives Exposure to persistent organohalogen pollutants was suggested to impair male reproductive function. A gene-environment interaction has been proposed. No genes modifying the effect of persistent organohalogen pollutants on reproductive organs have yet been identified. We aimed to investigate whether the CAG and GGN polymorphisms in the androgen receptor gene modify the effect of persiste
Choroid plexus from rat, guinea-pig, rabbit and pig was investigated by light-microscopic immunohistochemistry and by radioimmunoassay for the presence of neuropeptides. A moderately dense supply of nerve fibers containing neuropeptide Y (NPY) and vasoactive intestinal polypeptide (VIP), respectively, was found around blood vessels and in close relation to the secretory epithelium in both pig and
BACKGROUND: Statins reduce cardiovascular events and progression of carotid intima-media thickness (IMT). beta-Blockers are also known to reduce cardiovascular events, but less is known about their effects on carotid IMT. METHODS AND RESULTS: We conducted a randomized, double-blind, placebo-controlled, single-center trial to compare the effects of low-dose metoprolol CR/XL (25 mg once daily) and f
