Tidskriftsartikel (refereegranskat)abstract
- This article deals with the psychological description of the sports career, including the history of the topic in Russian sport psychology before and during perestroika, two theoretical models of the sports career (synthetic and analytic), and conclusions drawn from the empirical research of sports careers of more than 200 Russian athletes representing different sports specializations and levels of achievement. Seven predictable crises of elite sports careers are considered from the perspective of typical problems and difficulties of athletes in each crisis, general symptoms and possible circumstances that reinforce crisis symptoms, ways to resolve a crisis, the influence of a crisis on sport performance, forms of ''payment'' for failure to resolve crises, and ways of providing psychological assistance to athletes in crisis periods of the sports career.

High Sensitivity VLBI at 86 GHz : First Fringes with the 100 m Radio Telescope at Effelsberg
- 1993

Ingår i: VLBI Technology. - Tokyo : Terra Scientific. - 4887041128 ; , s. 75-85

Bokkapitel (refereegranskat)abstract
- Inclusion of large and sensitive antennas is of essential importance to further improve the imaging capabilities of VLBI at 3.5 mm wavelength. The combination of the 100 m radio telescope at Effelsberg (illuminated diameter ~60 m at lambda = 3.5 mm) with the 30 m radio telescope at Pico Veleta presently allows the detection of compact flux down to a level of 0.2 Jy (for τ=360 seconds integration time). Fringes have been found for 23 radio sources many of them not observed previously with VLBI at 86 GHz. On European baselines to Effelsberg the SNR typically was 10 to 30 (and ranged up to 107 for 3C279), facilitating model fitting for the brightest sources. Even in spite of chaning weather conditions during the observations (coherence times ranged between 10 to 100 seconds) and a still non-optimum pointing model for the 100 m antenna for observations at high frequencies, these results demonstrate that the 100 m radio telescope can be successfully incorporated in global VLBI experiments at 3.5 mm wavelength.

Bokkapitel (refereegranskat)abstract
- A series of 3.6 cm VLBI maps of 3C345 (1980.79 to 1988.38) is presented. The evolution of the jet components in this quasar is briefly discussed. Recent behavior of component C5 is described and the presence of a new component, tentatively labeled C6, is suggested.

- To make the hierarchical architecture, the neural networks of different type and different unsupervised learning techniques were combined. The classification accuracy obtained from such architecture is high enough to use it in the print quality control.

Image analysis and artificial neural network for colour classification in multicolour newspaper printing

- Automatic inspection of printed multicoloured screen pictures demands methods for colour classification of screen dots and pans of screen dots directly in an arbitrary picture. The paper describes a technique using colour image analysis and artificial neural network for inverse colour separation. For every arbitrary small part of a coloured picture it is determined which coloured inks that have been printed in that part. Special attention is paid to the problem of seperating between black colour produced by black ink and black colour produced by combining cyan, magenta and yellow ink. The technique is tested on multicoloured newsprint and a high correct colour classification rate has been demonstrated.

- Somatic hybrid plants of various ploidy levels obtained after chemical fusion between two dihaploid clones of potato Solanum tuberosum L. have been analysed by cytological, morphological and molecular methods. The hybrid nature of tetraploid and hexaploid plants and the genome dosage in hexaploid hybrids were confirmed by Giemsa C-banding. Tetraploid and hexaploid hybrids showed numerical as well as structural chromosome mutations. The latter occurred mainly in the nuclear organizing chromosome. The tetraploid hybrids were more vigorous than the dihaploid parents as demonstrated by an increase in height, enlargement of leaves, increase in the number of internodes, restored potential for flowering and increased tuber yield. The grouping of tetraploid somatic hybrids into various classes on the basis of leaf morphology revealed that plants with a full chromosome complement were more uniform than aneuploids. Many hexaploid somatic hybrids were also more vigorous than the dihaploidparents and could be grouped into two different classes on the basis of floral colour and tuber characteristics, the differences being due to their different dosage of parental genomes. Most of the tetraploid somatic hybrids showed pollen development halted at the tetrad stage as one of the parental clones contained a S. Stoloniferum cytoplasm. However, one tetraploid plant produced pollen grains with high viability. The chloroplast genome in the hybrid plants was determined by RFLP analysis. All of the hybrids had a cpDNA pattern identical to one parent, which contained either S. Tuberosum or S. Stoloniferum cpDNA. A slight preference for S. Tuberosum plastids were observed in hybrid plants. No correlation between pollen development and plastid type could be detected. © 1992 Springer-Verlag.

Tidskriftsartikel (refereegranskat)abstract
- A culture protocol has been developed for mesophyll protoplasts isolated from various dihaploid clones of potato. A special effort was made to promote the growth of initially dividing cells to form cell colonies and calli. An increase in plating efficiency in 3 different dihaploid clones and one doubled dihaploid clone was obtained after serial dilution of cultures with a suitable amount and type of medium at different stages of cell colony development. Plating on a refined semi-solid medium after 14 days of culture further improved both the yield and the quality of calli obtained. The refined plating medium also enhanced shoot regeneration ability from 67 to 90% in one of the dihaploid clones (67:9). The refined culture protocol could also be used without causing a decrease in plating efficiency at a low population density adjusted after 3 days of culture. The ploidy level of plants regenerated from dihaploid protoplasts were determined by chromosome counting and DNA analysis by flow cytometry. Most of the plants were aneuploid or tetraploid although, some dihaploid plants were obtained after protoplast culture of 2 dihaploid clones derived from the same cultivar (cv. Stina).
