The lifetime of the metastable level 3d(21)G(4) in a singly charged scandium has been experimentally investigated at the ion storage ring CRYRING. A laser probing technique has been used for the studies. We also report calculated lifetimes and transition rates for 10 metastable levels in Sc II, including the 3d(21)G(4) state, by calculations using configuration interaction wave functions. The life

Illumination of a chick’s eye allows light to pass through to the retina of the contralateral eye. Electroretinographic (ERG) recording employing the scalp or comb as a reference results in shorter implicit time, higher amplitude and lower sensitivity during the day than during the night in a light:dark (LD) cycle and in constant darkness (DD). ERG recordings employing the contralateral eye as ref

This paper demonstrates that light diffraction tomography can be used to measure the acoustic field of micromachined ultrasonic transducers (MUT) in cases in which standard methods like hydrophone and microphone measurements fail. Two types of MUTs have been characterized with the method, one air-coupled capacitive MUT (cMUT) and one waterloaded continuous wave (CW) miniature multilayer lead zirco

A personal diary may be more appropriate than a questionnaire for assessing self-reported current use of hormone therapy (estrogens, progestagens, or their combination); however, use of a questionnaire is more feasible and less expensive. The authors compared both methods for 16,060 Swedish women aged 45-73 years from the Malmo Diet and Cancer Study (baseline, 1991-1996). In a reliability analysis

The combination of environmental chamber exposure and bronchoalveolar lavage (BAL) was used to study the effects of the common air pollutant nitrogen dioxide (NO2). Eighteen healthy nonsmokers were exposed to NO2 during 20 min in an exposure chamber during light bicycle ergometer work. All subjects were examined with BAL at least 3 wks before exposure, as a reference. The subjects were re-examined

Objectives: To evaluate the importance of different autoantibodies against modified low-density lipoprotein (LDL) in patients with coronary artery disease (CAD). Background: Previous studies of autoantibodies against LDL have shown that patients with CAD have increased titers of autoantibodies against LDL modified by copper and malondialdehyde (MDA), whereas there is a lack of information about au

Particle image velocimetry is applied to measure the vertical (r-z) plane flow structures in a light-duty direct-injection diesel engine with a realistic piston geometry. The measurements are corrected for optical distortions due to the curved piston bowl walls and the cylindrical liner. Mean flow fields are presented and contrasted for operation both with and without fuel injection and combustion

Precipitates formed due to Fe(II)-oxidation catalysed by Acidithiobacillus ferrooxidans between pH 1.6 and 3.2 have been studied by powder X-ray diffraction, infrared spectroscopy and Mossbauer spectroscopy. The precipitates consist of well crystalline, ammonium-containing jarosite at pH 1.6, and mixtures of jarosite and poorly crystalline schwertmannite at pH 2.5 and 3.2. At low temperatures ( 10

Efficient screening of ligands interacting with G-protein-coupled receptors is central for modern drug development. Here, we describe an optimized reporter vector primarily intended for use in reporter cell lines expressing such receptors. The construct consists of a synthetic enhancer containing 9x TRE (12-O-tetradecanoylphorbol-13-acetate-responsive elements) fused to a minimal CMV (cytomegalovi

ST-segment measurements in the standard 12-lead electrocardiogram (ECG) of patients with acute coronary syndromes are crucial for these patients' management. Our objective was to determine whether the 12-lead ECG derived from the 3-lead EASI system can attain a level of diagnostic performance similar to that of the Mason-Likar (ML) 12-lead ECG acquired in clinical practice (CP) by paramedics and e

Background: Apolipoprotein (apo) M may exert anti-atherogenic properties in experimental studies. Its hepatic gene expression may be linked to glucose and lipid metabolism. Plasma apoM is decreased in obese mouse models. We hypothesized that plasma apoM is lower in metabolic syndrome (MetS) subjects, and determined whether intima media thickness (IMT) is associated with apoM. Methods: In 19 non-di

Among the Gram-positive anaerobic bacteria associated with clinical infections, the Gram-positive anaerobic cocci (GPAC) are the most prominent and account for approximately 25-30% of all isolated anaerobic bacteria from clinical specimens. Still, routine culture and identification of these slowly growing anaerobes to the species level has been limited in the diagnostic laboratory, mainly due to t

Offline foveation is a technique to improve the compression efficiency of digitized video. The general idea behind offline foveation is to blur video regions where no or a small number of previewers look without decreasing the subjective quality for later viewers. It relies on the fact that peripheral vision is reduced compared to central vision, and the observation that during free-viewing humans

Psychosocial stress at work is one of the most important factors behind increasing sick-leave rates. In addition to work stressors, it is important to account for non-work-related stressors when assessing stress responses. In this study, a modified version of the Stress-Energy Questionnaire (SEQ), the SEQ during leisure time (SEQ-LT) was introduced for assessing the affective stress response durin

Regional Studies. This study investigates the relationship between labour market externalities and regional growth based on real labour flows. In particular, it tests for the importance of labour mobility across so-called skill-related industries between 435 four-digit industries within 72 Swedish functional regions (1998-2002). Both the fixed-effect models and generalized method of moments (GMM)
