High-resolution spectra of the chemically peculiar HgMn stars chi Lupiand HR 7775, obtained with the Hubble Space Telescope/Goddard HighResolution Spectrograph, are investigated for their abundance of bismuthby comparison with LTE synthetic spectrum modeling. HR 7775, previouslyknown from International Ultraviolet Explorer spectra to display stronglines of Bi II, is determined to have bismuth pres

This thesis deals with techniques for the full integration of radio frequency (RF) transmitter with CMOS technology. The theory and implementation of high performance digital-to-analog converters (DACs) for radio frequency (RF) transmitters have been studied. A linear interpolation DAC architecture is proposed. By employing the linear interpolation, the attenuation of DAC's image components is sig

The crystal structure of the phosphide-bridged cluster [Os6(μ-H)(CO)12(NCMe)(μ-PH2)] 4 has been determined. The cluster consists of two Os3 triangles which are linked by a PH2 moiety which is terminally bound to each triangle. The acetonitrile ligand is axially coordinated and the hydride bridges the Os---Os edge to which the phosphide moiety and the acetonitrile are coordinated. The molecular str

Objectives: To identify genetic and non-genetic risk factors for papillary serous uterine cancer. Methods: A case-control study was conducted. Case women with papillary serous uterine cancer were compared with two control groups: 1) women with endometrioid uterine cancer and 2) healthy women with no past history of cancer. Cases and controls were matched for age (within two years) and ethnic group

Patients with dysphagia, heartburn and chest pain are regularly referred for radiologic evaluation of swallowing. The liquid barium swallow has been of great value for the biphasic evaluation of the pharynx and esophagus. Though many patients complain of dysphagia specifically for solids, solid bolus swallow is usually not part of the evaluation. For the present study we therefore included the use

There are four peptidyl-proline bonds in the 64-residue protein chymotrypsin inhibitor 2 (CI2), all of which are in the trans conformation in the native structure. The isomerisation of one or more of these peptidyl-proline bonds to the cis conformation in the denatured state gives rise to heterogeneity, leading to both fast and slow-folding species. The refolding of the fast-folding species, which

The Malmo protocol for immune tolerance induction uses intermittent injections of factor VIII/IX together with intravenous IgG and cyclophosphamide. In order to increase the production of antigen-antibody complexes, and also to improve cost-efficacy, we applied continuous infusion instead of intermittent injection in 5 high-responders (3 hemophilia A and 2 hemophilia B). All treatment attempts fai

Identifying genes involved in the disease pathways of complex diseases such as Rheumatoid arthritis (RA) has been shown to be very difficult. Despite decades of research still only a handful of genes have been convincingly identified as risk genes. RA is a common autoimmune disorder that affects approximately 1% of the population and knowledge of the contributing genetic factors would greatly incr

Man kan identifiera fem stora kundsegment på energimarknaden, nämligen hushåll i småhuslägenheter, hushåll i flerbostadshusens lägenheter, fastighetsägare till flerbostadshus, unga hushåll samt medelålders och äldre hushåll. Jämfört med energiföretagens andra kundsegment inom exempelvis industri, handel, service eller myndigheter är hushållssegmenten oorganiserade. De innehåller många hushåll med

The cells of most normal and malignantly growing tissues are connected by "adhering junctions", i.e. distinct sites of "homotypic" contact between the plasma membranes of two cells of the same or a similar kind, associated on the cytoplasmic side by a dense plaque at which often bundles of cytoskeletal filaments anchor. Of the various types of adhering junctions desmosomes are characteristic of ep

This was the second nordic seminar on moisture transport. The first meeting was held in Kopenhagen-Lyngby in 1989. The majority of the researchers who met in Ystad works with building materials at Technical Institutes or Universities in Denmark, Finland, Norway and Sweden. We discussed different aspects of moisture transport, including: • non-isothermal conditions • moisture flow at surfaces • dif

The potential of algal–bacterial microcosms was studied for the biodegradation of salicylate, phenol and phenanthrene. The isolation and characterization of aerobic bacterial strains capable of mineralizing each pollutant were first conducted. Ralstonia basilensis was isolated for salicylate degradation, Acinetobacter haemolyticus for phenol and Pseudomonas migulae and Sphingomonas yanoikuyae for

The remaining carbon stocks in wet tropical forests are currently at risk because of anthropogenic deforestation, but also because of the possibility of release driven by climate change. To identify the relative roles of CO2 increase, changing temperature and rainfall, and deforestation in the future, and the magnitude of their impact on atmospheric CO2 concentrations, we have applied a dynamic gl

This study investigated whether there is an association between bone density and features of the metabolic syndrome in relation to hormonal status. All women aged 50 to 59 years living in a defined geographic area in Sweden were offered a health assessment program including blood glucose, lipid profile, blood pressure, and bone densitometry. Women were divided into 3 groups according to their horm

Popular Abstract in Swedish Fuktbuffring i inomhusmiljön är ytmaterialens förmåga att, genom absorption och desorption, dämpa luftens fuktighetsvariationer. Fuktbuffring spelar en viktig roll i förståelsen av risker för biologisk tillväxt i ytmaterial, t.ex. mögel på väggar och husdammskvalster i sängar. Därigenom är fuktbuffring viktig ur hälsosynpunkt. Förutom hälsoaspekterna är kunskap om fuktbMoisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g., mold growth on walls and house dust mites in beds, and thereby also have an impac

The performance of a 5' nuclease real-time PCR assay was studied to optimize an automated method of detection of preenriched Salmonella enterica cells in buffered peptone water (BPW). The concentrations and interactions of the PCR reagents were evaluated on the basis of two detection responses, the threshold cycle (C(T)) and the fluorescence intensity by a normalized reporter value (DeltaR(n)).
