The effect of microbial desulfurization of two different low-sulfur coals by the thermophilic archaebacteria Acidianus brierleyi was studied with respect to the following properties of the coal: porosity, surface area, pore diameter, particle size, heating value, proximate and ultimate analyses as well as ash composition. About 35-40 percent of the sulfur was oxidized microbially. The microbial tr
Communication is generally regarded as an essential aspect of diplomacy. Proceeding from an understanding of diplomacy as a transhistorical phenomenon, this article distinguishes a number of pertinent dimensions of the communicative aspects of diplomacy and proffers examples taken from different eras and geographic regions. With a focus on continuity and change, the article analyzes the basic aspe
For the first time, in situ alkaline phosphatase activity (APA) was studied at the species level in a natural spring community of freshwater phytoplankton. This was achieved by utilizing a substrate called enzyme labeled fluorescence (ELF), which forms fluorescent precipitates at the site of APA. Samples collected from Lake Erken, Sweden, were assayed with ELF and a number of species belonging to
The present doctoral thesis is a study of the problem of "variation" in relation to word stress in Russian adjectives, in both their short and long forms. The stress variation in adjectival forms is investigated from various viewpoints, the main of which is the revelation of the basic processes of stress reorganisation in these groups of words and the establishment of main tendencies of adjectival
Biglycan is widely distributed in the extracellular matrix and is a member of the small proteoglycan family characterized by a core protein with leucine-rich repeat motifs. We show in this paper for the first time that biglycan from human lung fibroblasts can be expressed as different isoforms. These isoforms can be separated from the predominant form of biglycan by hydrophobic interaction chromat
Popular Abstract in Swedish Molekylärgenetiska och funktionella studier av BCR/ABL1 fusionsgenen: Det finns tre sorters blodkroppar, röda, vita och trombocyter, som alla bildas från gemensamma stamceller i benmärgen. När stamcellerna delar sig bildas det antingen nya stamceller eller förstadier till blodkroppar som efter ytterligare delningar blir till mogna blodkroppar. Ibland uppkommer särskildThe BCR/ABL1 fusion gene is associated with chronic myeloid leukemia and a subgroup of acute lymphoblastic leukemia. The general aim of this thesis was to increase the understanding of BCR/ABL1-induced leukemogenesis by molecular and functional studies of this fusion gene. In Article I, an experimental U937 cell line model with inducible expression of BCR/ABL1 was established and characterized. Ex
Embedded declarative V2 clauses can appear in a number of different contexts in Norwegian and Swedish. What all these clauses have in common is that they have illocutionary force—they are asserted. I argue that a syntactic Force head is responsible for the illocutionary force as well as for the V2 order. Thus, the syntax and the semantics of embedded V2 clauses are closely tied together. The analy
OBJECTIVE--To investigate whether a lack of glutathione-S-transferase mu (GSTM1) activity was related to an increased risk for adverse outcome after asbestos exposure. METHODS--A study was made of 78 male former asbestos cement workers, with retrospective cohort data on exposure, radiographical findings, and lung function. Venous blood samples were obtained for the analysis of GSTM1 polymorphism b
Recent progress shows that neurons suitable for transplantation can be generated from stem cells in culture, and that the adult brain produces new neurons from its own stem cells in response to injury. These findings raise hope for the development of stem cell therapies in human neurodegenerative disorders. Before clinical trials are initiated, we need to know much more about how to control stem c
The problem of constructing generalized point interactions of the second derivative operator in L-2( R) leading to the same scattering data as for reflectionless potentials is considered. It is proved that this problem has a solution only if extensions in Pontryagin spaces are involved. The solution of the inverse scattering problem is not unique, this is illustrated by considering the scattering
In this paper we demonstrate a fast correlation attack on the recently proposed stream cipher LILI-128. The attack has complexity around 2(71) bit operations assuming a received sequence of length around 2(30) bits and a precomputation phase of complexity 2(79) table lookups. This complexity is significantly lower than 2(112), which was conjectured by the inventors of LILI-128 to be a lower bound
Based on a literature review and the SSG experience, the most important prognostic factors in high-grade osteosarcoma appear to be the presence of detectable metastases at diagnosis, tumour volume, old age, sex, histologic response, and possibly tumoral P-glycoprotein expression. However, for an adolescent patient with non-metastatic extremity disease, there is no consensus regarding prognostic fa
Gel electrolytes were prepared by swelling a self-assembling ABA triblock copolymer with different amounts of a solution of I M lithium bis(trifluoromethylsulfonyl)imide salt in gamma-butyrolactone. The triblock copolymer had endblocks of polyethylene (PE) and midblocks of poly(ethylene oxide-co-propylene oxide) (PEOPO), where the former blocks constituted 10 wt% of the copolymer. Thus, the electr
It was recently proposed to use variational functionals based on many-body perturbation theory for the calculation of the total energies of many-electron systems. The accuracy of such functionals depends on the degree of sophistication of the underlying perturbation expansions. An older such functional and a recently constructed functional, both at the level of the GW approximation (GWA), were tes
The article discusses the usefulness of the concept of North Eastern Europe. It was developed as a cognitive instrument in order for historical analysis to focus on social structures and processes rather than on states. Swedish historical consciousness is linked to the history of the seventeenth century, not least thanks to the historical novels by Peter Englund, Sweden of those times was a multin
gamma -Carboxylated proteins were detected in normal human pancreas by immunohistochemistry with a monoclonal antibody (M3B) specific for gamma -carboxyglutamyl residues, Staining appeared to be localized to the glucagon-secreting alpha -cells in the islets of Langerhans, Consistent with this, sections from a glucagonoma were stained much more intensely with the M3B antibody than those from an ins
