Abstract: Catalysts used for selective catalytic reduction of NOx on diesel engines were deactivated for 890 and 2299 h in the exhausts from a diesel engine running on Swedish diesel fuel mark 1. The deactivated catalytic monoliths (100 mm long) were cut in 10 mm pieces along their axis and were characterized by physicochemical methods as well as by determination of the activity in the reduction o
A measurement of the W mass and width has been performed by the DELPHI Collaboration using the data collected during 1998. The data sample has an integrated luminosity of 155 pb-1 and an average centre-of-mass energy of 188.6 GeV. Results are obtained by applying the method of direct reconstruction of the mass of the W from its decay products in both the W+W- → lvlqq′ and W+W- → qq′qq′ channels. T
Microorganisms in soil are commonly limited by available substrate, and removing the limitation will increase activity and growth, with predictable dynamics in growth. The initial phase with a lag period (λ) will usually be followed by exponential growth (also called log phase, with growth rate μ). These two growth phases may be differently affected by environmental conditions, like temperature an
The neutron-deficient mercury isotopes serve as a classical example of shape coexistence, whereby at low energy near-degenerate nuclear states characterized by different shapes appear. The electromagnetic structure of even-mass 182-188 Hg isotopes was studied using safe-energy Coulomb excitation of neutron-deficient mercury beams delivered by the REX-ISOLDE facility at CERN. The population of 01,2
The effect of secretin on glucagon and insulin release and its interaction with glucose has been studied in cultured mouse pancreatic islets by column perifusion. Glucose alone showed the well-known stimulation of insulin release and inhibition of glucagon release. Addition of 10 mM secretin increased glucagon secretion at 3 mM d-glucose by 300% while no change in insulin release could be seen at
Disturbed cellular cholesterol homeostasis may lead to accumulation of cholesterol in human atheroma plaques. Cellular cholesterol homeostasis is controlled by the sterol regulatory element-binding transcription factor 2 (SREBF-2) and the SREBF cleavage-activating protein (SCAP). We investigated whole genome expression in a series of human atherosclerotic samples from different vascular territorie
Background: Renal insufficiency is a serious complication of lithium treatment. Therefore, regular monitoring of plasma (P) creatinine is always part of lithium treatment safety routines. Recently P-cystatin C-estimated glomerular filtration rate (cystatin C-eGFR) had been launched as a preferable alternative to P-creatinine. Aims: To find out which of the two alternatives to prefer in the safety
Chronic obstructive pulmonary disease (COPD) is an irreversible disease, diagnosed predominantly in smokers. COPD is currently the third leading cause of death worldwide. Far more than 15 % of smokers get COPD: in fact, most develop some amount of pulmonary impairment. Smoking-related COPD is associated with both acute exacerbations and is closely correlated to comorbidities, such as cardiovascula
BACKGROUND: Substance use disorders have repeatedly been found to lead to premature death, i.e. drug-related death by disease, fatal intoxications, or trauma (accidents, suicide, undetermined suicide, and homicide). The present study examined the relationship between multi-drug substance use and natural and unnatural death. METHODS: All consecutive, autopsied patients who had been in contact with
PURPOSE: The purpose of this study was to observe sickness absence before and after the cancer diagnosis among cancer patients with five common forms of cancer. METHODS: Using cohort data, we observed sick leave in the pre- and post-diagnostic phase among patients with colon, rectal, breast, prostate, or lung cancer (n = 2,738). We also identified reference subjects without cancer (total n = 12,24
Adequate intravenous contrast media (CM) enhancement is crucial for evaluation of the coronary arteries.
Advanced driving assistance systems that offer support by operating for example longitudinal control will have an effect on the transport system. Previous studies have also shown that drivers may be slower to respond in hazardous situations with systems like adaptive cruise control (ACC) engaged, if the system suddenly fails. Little understanding has, so far, emerged to explain why. In this thesis
Between February 1999 and July 2000, a team of researchers from Britain, Denmark, France, and Sweden carried out a telephone survey, background investigations, and six expert seminars in Central and Eastern Europe, with the purpose of exploring the consequences and implications of the spread of ISO 14001 and EMAS in this region. The telephone survey, carried out during the summer of 1999, targeted
Hemodynamic effects of iso-oncotic 3% dextran-60, 6% dextran-70, and Ringer's acetate were compared in 28 male pigs (25 to 30 kg) subjected to experimental trauma and hemorrhage. The animals were kept anesthetized with 75% N2O/25% O2, 0.8% halothane. Hemodynamic and respiratory conditions were allowed to stabilize for one hour preoperatively (baseline data). After surgical trauma (arthroplasty), t
