Purification and characterization of chitinases from the nematophagous fungi Verticillium chlamydosporium and v. suchlasporium
Culture filtrates of the nematophagous fungi Verticillium chlamydosporium and V. suchlasporium growing on colloidal chitin showed increasing chitinolytic activity and production of two (32- and 43-kDa) main proteins. Maximum activity was found 18-20 days after inoculation, but V. suchlasporium always displayed higher activity. Zymography of such filtrates on carboxymethyl-chitin-Remazol brilliant
The Bismuth Abundance in the HGMN Stars chi Lupi and HR 7775 and Improved Atomic Data for Selected Transitions of BI I, BI II, and BI III
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
Linear Interpolation D/A Converter Applied to Direct Digital RF Modulators
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 and Molecular Structure of HOs6(CO)21(NCMe)PH2
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
Familial and hormonal risk factors for papillary serous uterine cancer
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

Solid bolus swallowing in the radiologic evaluation of dysphagia
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
The Rate of Isomerisation of Peptidyl-proline Bonds as a Probe for Interactions in the Physiological Denatured State of Chymotrypsin Inhibitor 2
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
Regimens of factor VIII administration--continuous infusion vs. bolus
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
Genetic and genomic analysis of arthritis regulating regions in human and mouse
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

Hushållskunder på elmarknaden: Värderingar och beteenden
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
Desmosomes--dual junctional principles of intra- and supracellular order in epithelial differentiation and tissue formation
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

Metaphors, Thought and Theory: The Case of Neo-Realism and Bipolarity
Calculation of moisture transport and the necessary material data : Nordic symposium, January 28-29 1991 Ystad, Sweden
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
Synergistic relationships in algal-bacterial microcosms for the treatment of aromatic pollutants.
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
Tropical forests and the global carbon cycle: impacts of atmospheric carbon dioxide, climate change and rate of deforestation
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
The influence of hormonal status and features of the metabolic syndrome on bone density: A population-based study of Swedish women aged 50 to 59 years. The women's health in the Lund area study
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
