The vortex state of FeSe1-xTex superconducting thin films
We report the vortex dynamics of tellurium substituted FeSe1-xTex superconducting thin films. The electric field versus current density (E-J) curve for films with low Te substitution is still governed by the thermally activated flux flow model at temperatures as low as 0.5T(C)(offset). In contrast, we clearly observed a vortex liquid-glass transition in films with high Te substitution. The E-J cur
Adsorption of chloromethane molecules on free argon clusters
Binary chloromethane-argon clusters were investigated by means of synchrotron-radiation-based valence and core level photoelectron spectroscopies. The host argon clusters were produced by adiabatic expansion and exposed to chloromethane molecules using the pick-up technique. The study of the valence spectrum showed that heterogeneous clusters were formed. The spatial distribution of chloromethane
Vitamin K-dependent protein S - studies of synthesis, structure and function
This thesis is based on four projects with the overall aim to investigate vitamin K-dependent protein S functions in relation to its structure. The anticoagulant functions of protein S can be divided in three: 1) cofactor for activated protein C (APC), 2) cofactor for tissue factor pathway inhibitor (TFPI) and 3) APC and TFPI-independent anticoagulant functions. Microparticles might be shed from
Influence of Polymorphisms in the RANKL/RANK/OPG Signaling Pathway on Volumetric Bone Mineral Density and Bone Geometry at the Forearm in Men
We sought to determine the influence of single-nucleotide polymorphisms (SNPs) in RANKL, RANK, and OPG on volumetric bone mineral density (vBMD) and bone geometry at the radius in men. Pairwise tag SNPs (r (2) a parts per thousand yen 0.8) for RANKL (n = 8), RANK (n = 44), and OPG (n = 22) and five SNPs near RANKL and OPG strongly associated with areal BMD in genomewide association studies were pr

Intrahost evolution of HIV-1 phenotypes
HIV-1 evolves constantly within an infected individual, due to its mutation-prone viral enzyme, high viral turnover and pressure from the host immune system. Therefore, viruses isolated at different time points from the same individual are never exactly the same and, accordingly, rarely function the same way. However, if we can understand how HIV-1 phenotypically evolves in the newly infected host
Ultrafast charge delocalization dynamics in aqueous electrolytes: New insights from Auger electron spectroscopy
We review the basic principles of ultrafast charge delocalization phenomena in aqueous electrolytes following core-level photoionization and resonant core-level excitations, and describe how these processes can be probed using Auger electron spectroscopy. The use of the core-hole clock method to extract dynamical information from Auger spectra is described. By a number of examples we demonstrate h
INOSITOL PHOSPHOLIPID-BASED SIGNAL TRANSDUCTION IN PLANTS Phosphoinositide-Specific Phospholipase C and 3-Phosphoinositide Dependent Protein Kinase-1 in Arabidopsis thaliana
Popular Abstract in Swedish Alla levande organismer måste kunna anpassa sig till förändringar i sin omgivning, såsom kyla, värme eller torka. Vid sådana förändringar tar enskilda celler emot signaler ifrån sin omgivning via särskilda s.k. receptorproteiner på cellytan. Receptorproteinerna skickar signalerna vidare in i cellen, där de kan ge upphov till en kedja av processer, vilka slutligen leder Phosphoinositides (PIs) play major roles in cell signal transduction. Although it is clear that PIs are important components also in plant signalling, little is known about their roles in plant cells, compared to animal cells. This thesis describes work on two PI-dependent enzymes involved in plant intracellular signalling, phosphoinositide-specific phospholipase C (PI-PLC) and 3-phosphoinositide
Improving the biocatalyst. Engineering of fungal oxidoreductases and thin-film electrodes for improvement of membraneless biofuel cells and carbohydrate biosensors.
This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying
Mapping activities of artists in the past: A bibliometric study of the library of the Scandinavian Association in Rome to 1870
The purpose of this study is to conduct a bibliometric analysis of the library collection at the Scandinavian Association in Rome. Data were gathered from the library catalog and then submitted to frequency and co-occurrence analyses. By examining keywords, authors, and the language of the books found in the library, we were able to draw conclusions about its role as a social rather than an academ
Total Serum Cholesterol and Cancer Incidence in the Metabolic Syndrome and Cancer Project (Me-Can)
Objective: To investigate the association between total serum cholesterol (TSC) and cancer incidence in the Metabolic syndrome and Cancer project (Me-Can). Methods: Me-Can consists of seven cohorts from Norway, Austria, and Sweden including 289,273 male and 288,057 female participants prospectively followed up for cancer incidence (n = 38,978) with a mean follow-up of 11.7 years. Cox regression mo
Dynamics in carbon exchange fluxes for a grazed semi-arid savanna ecosystem in West Africa
The main aim of this paper is to study land-atmosphere exchange of carbon dioxide (CO2) for semi-arid savanna ecosystems of the Sahel region and its response to climatic and environmental change. A subsidiary aim is to study and quantify the seasonal dynamics in light use efficiency (epsilon) being a key variable in scaling carbon fluxes from ground observations using earth observation data. The n
Silver and palladium help unveil the nature of a second r-process
Context. The rapid neutron-capture process, which created about half of the heaviest elements in the solar system, is believed to have been unique. Many recent studies have shown that this uniqueness is not true for the formation of lighter elements, in particular those in the atomic number range 38 < Z < 48. Among these, palladium (Pd) and especially silver (Ag) are expected to be key indicators
Resonant inelastic X-ray scattering at the Be 1s edge in BeO
We present the resonant inelastic X-ray scattering (RIXS) spectra of BeO at the Be 1s photoabsorption edge. The RIXS spectra excited in the vicinity of the core exciton resonance show two principal features: the scattering on a valence exciton (which at higher excitation energies verges into the characteristic K alpha emission), and a remarkably strong energy loss side-band to the elastic scatteri
Development of Methods for Measuring Protein C Inhibitor and Antithrombin: Use of Monoclonal Antibodies against the Reactive Center Loop-Inserted Forms of the Serpins
Protein C inhibitor (PCI) and antithrombin (AT) are serine protease inhibitors (serpins) that are involved in the regulation of coagulation. Like other inhibitory serpins, PCI and AT adopt different structural conformations that are related to their functions. The cleaved, inactive form is a result of cleavage by a protease, and the latent form, which is also inactive, can arise due to a mutation
Lineshapes in carbon 1s photoelectron spectra of methanol clusters
Recurrence in patients with oral and oropharyngeal squamous cell carcinoma: human papillomavirus and other risk factors.
Conclusions. The results confirm that tumour stage influences the risk of recurrence/second primary tumour (SPT). High-risk human papillomavirus (HPV)-infected patients have a significantly higher risk of recurrence/SPT compared with high-risk HPV-negative patients. High alcohol consumption was associated with a higher risk of recurrence/SPT. In this study, the competing risk of death in intercurr
Investigation of graphite electrodes modified with cellobiose dehydrogenase from the ascomycete Myriococcum thermophilum
The catalytic properties of cellobiose dehydrogenase (CDH) from the ascomycete fungus Myriococcum thermophilum adsorbed on a graphite electrode were investigated for a large variety of carbohydrate substrates. The effects of applied potential, pH and buffer composition were tested and optimized, and the most suitable conditions were used to evaluate the detection limit, linear range, and sensitivi
Lifetime fitness of short- and long-distance dispersing great reed warblers
Dispersal is of prime importance for many evolutionary processes and has been studied for decades. The reproductive consequences of dispersal have proven difficult to study, simply because it is difficult to keep track of dispersing individuals. In most previous studies evaluating the fitness effects of dispersal, immigrants at a study locality have been lumped into one category and compared to ph
