The described element is intended to provide a substantial information about the protected document if stolen, and then tracked. Its major use is supposed for archives, galeries, museums, art collections etc. It contains a combination of specific elements from the periodic table with a distinctive XRF response. Ususally there are four elements in use. Their combinations when using their diffrent amounts, typically up to 5 levels for each, allow a high number of codes to be encrypted.

The contents of endogenous brassinosteroids (BRs) together with various aspects of plant morphology, water management, photosynthesis and protection against cell damage were assessed in two maize genotypes that differed in their drought sensitivity. The presence of 28-norbrassinolide in rather high quantities (1-2 pg mg-1 fresh mass) in the leaves of monocot plants is reported for the first time. The intraspecific variability in the presence/content of the individual BRs in drought-stressed plants is also described for the first time. The drought-resistant genotype was characterised by a significantly higher content of total endogenous BRs (particularly typhasterol and 28-norbrassinolide) compared with the drought-sensitive genotype. On the other hand, the drought-sensitive genotype showed higher levels of 28-norcastasterone. Both genotypes also differed in the drought-induced reduction/elevation of the levels of 28-norbrassinolide, 28-norcastasterone, 28-homocastasterone and 28-homodolichosterone. The differences observed between both genotypes in the endogenous BR content are probably correlated with their different degrees of drought sensitivity, which was demonstrated at various levels of plant morphology, physiology and biochemistry.

The technical solution relates to a hydrolysate containing a mixture of amino acids, peptides and other biogenic substances prepared from a troublesome protein waste material containing keratin and fat, for example, from poultry feathers or animal hair. The hydrolysate, prepared in the presence of a weak carbonic acid containing no any extraneous substances, meet the raw material requirements for the preparation of complex nutrition mixtures applicable as animal feed and bio-stimulant or special fertilizers. The essence of the technical solution presented relates to the hydrolysate prepared in the presence of a weak carboxylic acid, e.g. malic acid at pressure below 1.0 MPa. and containing a mixture of amino acids, proteins, tri-acyl-glycerides, di-acyl-glycerides, mono-acyl-glycerides, aliphatic carboxylic acids, without any salts and low level of mineral ash forming components.

The technical solution concerns an optical device for pH measurement, eg in biological samples, using a fiber-optic probe with immobilized fluorescent dye

To have more detailed information about rock massif behaviour, distributed control and measurement network for evaluation of hydrologic, geomechanical and other parameters has been built up in the medieval Jeroným Mine from the first half of 2006. Instrumentation is generally based on commercial control kit and sensors. This network is integrated to the seismic recording apparatus equipped by data transmission via GSM network to registration centre in Ostrava. Completely monitoring system is performed as modular to have possibility to change configuration of this system.

Color-changing fluorescent nucleotide and oligonucleotide probes for studying interactions with other biomolecules were designed and prepared, and perform better than currently known environment-sensitive fluorophores.
