Effect of Selected Luminescent Layers on CCT, CRI, and Response Times.

Phosphors have been used as wavelength converters in illumination for many years. When it is excited with blue light, the frequently used yttrium aluminium garnet doped with cerium (YAG:Ce) phosphor converts a part of blue light to a wideband yellow light, resulting in the generated light having a white color. By combining an appropriate concentration of the YAG:Ce phosphor and blue excitant light, white light of a desired correlated color temperature (CCT) can be obtained.

Rabies-free status of the Czech Republic after 15 years of oral vaccination.

Rabies in foxes was widespread in the Czech Republic after World War II, reaching its highest incidence in the 1980s. Applied control measures had only a limited effect and rabies incidence in wildlife continuously endangered both domestic animals and human beings. A significant improvement was noticed after the introduction of oral vaccination of foxes in 1989.

Biodegradation of synthetic polymers by composting and fungal treatment.

Two types of copolymers--poly(ester-amide)s--by the anionic copolymerization of epsilon-caprolactam and epsilon-caprolactone, and aromatic-aliphatic copolyesters based on glycolyzed polyethylene terephthalate from used beverage bottles and epsilon-caprolactone were prepared. Biodegradation tests of these copolymers were performed by two methods, viz. composting under controlled conditions and treatment with ligninolytic fungi.

Elimination of rabies in the Czech Republic.

Rabies in foxes was widespread in the territory of the Czech Republic after the Second World War. The first three cases of fox rabies appeared in North and South Bohemia in 1947. In the following year, a considerable increase in rabies incidence was reported and of the 146 cases, 106 (74 %) of the 117 wildlife cases were in foxes.
