We present an abundance analysis of the very metal-poor, carbon-enhancedstar CS 29497-030. Our results indicate that this unusually hot turnoffstar (Teff = 6650 K, log g = 3.5) has a metallicity [Fe/H] =-2.8, and exhibits large overabundances of carbon ([C/Fe] = +2.38),nitrogen ([N/Fe] = +1.88), and oxygen ([O/Fe] = +1.67). This star alsoexhibits a large enhancement in its neutron-captu
Popular Abstract in Swedish Soffan är en stor och vanligt förekommande möbel. Hur viktig den är blir särskilt tydligt när människor själva planerar sina bostäder och ekonomin styr bostadens storlek. Erfarenheter från tre projekt med brukarinflytande i bostadsplanering ligger till grund för det här avhandlingsarbetet. I samtal kring soffan visar det sig att den är intimt förknippad med värderingar Experiences of participatory design with full-scale modelling in three case studies form the basis of this work. When the participants in these studies visualised their dwellings there was a strong focus on the sofa. This piece of furniture is one of the most common in Swedish homes. It also requires much space. Additionally, the lay-people focused on different kinds of functional needs while sitt
OBJECTIVES: Sleep deprivation has experimentally been shown to adversely influence glucose metabolism, endocrine function and sympathovagal balance in young men without known serious disease. We investigated the impact of sleep problems and resting heart rate in a large sample of self-reported, healthy middle-aged men and women on long-term mortality. METHODS: In all 22,444 men and 10,902 women pa
Cells continuously export, import, and recycle molecules over the plasma membrane. Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their surroundings for antigens and to fight microbes. Moreover, internalization regulates complex cellular signalli
New radiative lifetimes for 20 levels of Pr II have been measured using the time-resolved laser-induced fluorescence (LIF) technique. The combination of these experimental values with theoretical branching fractions (BF) obtained with the pseudo-relativistic Hartree-Fock (HFR) approach has allowed us to determine oscillator strengths and transition probabilities for about 150 lines appearing in th
A double stranded DNA based fluorescence bioprobe for anticancer agent (doxorubicin) detection is described. This method provides a new way for sensitive DNA/drug interaction study by a homogeneous assay. The probe employs the long-wavelength intercalating fluorophore TOTO-3((R)) (TT3). The anticancer agent, doxorubicin, which interacts with the DNA-TT3 complex, was indirectly measured by the decr
Six pigs were used to study whether the collection of shed blood by means of surgical compresses instead of suction traumatizes such blood. In an in vivo part of the study, the whole blood volume of the pigs was retransfused after treatment with citrated compresses, and in an in vitro part the blood was treated extensively with compresses and analyzed. All animals survived, with a minor fall in he
An international collaboration was organized to undertake a dosimetry exchange to enable the future combination of clinical data from different centers conducting neutron capture therapy trials. As a first step (Part I) the dosimetry group from the Americas, represented by MIT, visited the clinical centers at Studsvik (Sweden), VTT Espoo (Finland), and the Nuclear Research Institute (NRI) at Rez (
Clay minerals cannot only give information on sedimentary depositional environment but also the climate regime under which sediment was weathered. The successions of non-marine to marine Middle and Late Jurassic strata of the East European Platform show upwards increasing contents of smectite and decreasing contents of kaolinite. There is also an increasing smectite vs. kaolinite ratio laterally,
AIMS: This study sets out to investigate direct care staff's views of their need for support, supervision, and training in their practice in day care settings when supporting daily occupations among developmentally disabled persons. BACKGROUND: The first line staff are considered as having a prominent role in the successful delivery of service. METHODS: Three municipalities, one urban and two rura
This paper presents a novel event detector for implantable devices. The algorithm is based on a signal model which describes an event as a linear combination of basis functions. The linear combination involves two fundamental electrogram waveforms represented at different time scales. An efficient, low-complexity detector is developed using the dyadic wavelet transform with integer filter coeffici
A formalism for the calculations of electron transport in multiterminal quantum systems is presented. The systems are described by tight-binding Hamiltonians. It is shown that by exploiting real-space Green's functions, a problem of the electron transport in a multiterminal system can be reformulated into a problem of the electron transport in an effective two-terminal system and can then be treat
BACKGROUND/AIMS: Endoscopic sphincterotomy is an established treatment of retained or recurrent common bile duct calculi after cholecystectomy and in the majority of patients with an intact gallbladder. In order to identify patients ultimately requiring additional endoscopic procedures or surgery, factors predictive of decreased endoscopic bile duct clearance were sought. MATERIAL AND METHODS: Bet
OBJECTIVE: To evaluate the effects of the three commercially available colloid solutions, 6% dextran 70, 6% hydroxyethyl starch (HES) 200/0.5, and 3.5% urea-linked gelatin on permeability for human albumin in a skeletal muscle in vivo model by evaluating their effects on the reflection coefficient for albumin. DESIGN: Controlled laboratory study. SETTING: University research laboratory. SUBJECTS:
Naturally grown fruit-bodies of Suillus luteus, S. bovinus and S. variegatus were subjected to Py-GC. The pyrograms obtained were statistically analysed and classified with a multivariate classification program (SIMCA). The class describing the S. bovinus pyrograms was significantly separated from both the S. luteus and the S. variegatus classes, while these two classes showed some over-lapping wh
