Possibilities of financial support for the modification of the garden at the Kindergarten
ŠPÍRKOVÁ, Jana
The thesis deals with inadequate equipment in kindergarten gardens and with inadequate funds for the maintenance of existing facilities. In the literal retrieval, the thesis reviews available financial resources (from the municipal grant programmes to international grant programmes, provided by companies) which could be used for maintenance and renovation of kindergarten gardens. The level of success of various types of programmes was evaluated through questionnaire methods and the results are s ated in the practical part of the thesis. In the conclusion of the thesis there is an outline of a suggested solution which could be used by prospective grant applicants. One of the outcomes of this work is the preparation of project application for our kindergarten and its administration of the grant program.
Příprava optických vlnovodů ve speciálně navržených Er- a Yb- dotovaných silikátových sklech iontovou výměnou Ag.sup.+./sup./Na.sup.+./sup

Modification of the Ag.sup.+./sup./Na.sup.+./sup. exchange conditions was done in order to decrease optical losses and to modify n(x) profile of the waveguides. This was achieved using reaction melt with decreased Ag.sup.+./sup. content and consequent annealing of the samples.

The magnetron sputtering was used to fabricate RE doped GaN layers fabricated by magnetron sputtering on various substrate using a gaseous mixture of nitrogen and argon as precursors. The doping of the GaN films with RE occurred simultaneously with the sputtering process when placing the metal RE pellets or RE powder onto the Ga2O3 target. The amount of the incorporated erbium increased with increasing weight of the RE pellets or RE powder. We observed photoluminescence emission at 1 550 nm due to the 4I13/2 → 4I15/2 transition under excitation at 488 nm and 980 nm.
