The rRNA cistron (18S-ITS1-5.8S-ITS2-28S) is used widely for phylogenetic analyses. Recent studies show that compensatory base changes (CBC) in the secondary structure of ITS2 correlate with genetic incompatibility between organisms. Rhizoctonia solani consists of genetically incompatible strain groups (anastomosis groups, AG) distinguished by lack of(More)
Rhizoctonia solani is an important soilborne and seedborne fungal pathogen of potato (Solanum tuberosum). The initial infection of sprouts prior to emergence causes lesions and may be lethal to the sprout or sprout tip, which results in initiation and compensatory growth of new sprouts. They emerge successfully and do not suffer significant damage. The(More)
In the present study, the formation and further reactions of intact steryl ester hydroperoxides were followed in a tripalmitin matrix maintained at 100°C. The effects of the acyl moiety and its unsaturation degree, and of the sterol structure were investigated. Intact steryl ester hydroperoxides were isolated from the lipid matrix by a developed solid-phase(More)
AIMS To test interactions between pathogenic strains of Streptomyces turgidiscabies, S. scabies and S. aureofaciens. To study biological control of S. turgidiscabies and S. scabies using the nonpathogenic Streptomyces strain (346) isolated from a scab lesion and a commercially available biocontrol agent (S. griseoviridis strain K61; 'Mycostop'). METHODS(More)
Comprehensive two-dimensional gas chromatography utilising a semi-rotating cryogenic modulator was applied to the analysis of dietary milk derived fatty acids. Four column combinations were tested: two polar-nonpolar and two different nonpolarpolar column combinations. Best results were obtained with a nonpolar-polar column set, with narrow-bore (50 microm(More)
This paper reviews and identifies the distinct perspectives on knowledge management as well as the key conceptual views on competence and competence management. It introduces the perceivable co-evolution of knowledge management and competence management in recent research and practice, and shows the movement towards an integrated and systemic view where the(More)
Comprehensive two-dimensional gas chromatography utilising a semi-rotating cryogenic modulator was applied to the analysis of urban aerosols. Samples were collected onto glass fibre filters using a high-volume sampler in Helsinki, Finland. Sample preparation included extraction into n-hexane-acetone mixture and clean-up on silver-impregnated silica column.(More)
It is well known that the dynamics in business are changing. Companies need to be aware of changes in their business environment, have an ability to recognize and exploit opportunities through their rare and distinctive resources and capabilities. This depends on their dynamic ability to reinvent their capabilities, business models, and strategies as(More)
