The system coprises a thin element for the visual monitoring of the exposition dose. Its application is expected in various practical fields, such as phototherapy, museums, skin protection, food safety, phramaceuticals safety, construction materials, etc. The time variable is calibrated via the colour change. It is based on the utilisation of different stabilites of many tested chemicals. Their light induced decomposition is manifested as decolorization. The decolorization is described kinetically, and then associated in a cumultaive form with a certain characteristic dose. The dose reflects the amount of absorbed light, and it has many practical consequences in the mentioned fields.

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.

Solution relates to the preparation of new N-alkylamides of alginic acid of formula, in which are those the modification attending in the carboxylic acid groups by esterification followed by an amino-de-alkoxylation and by direct amidation or amino de alkoxylation of an ester to aid microwave heating. This modification results in attachment of various long chain alkyl (depending on the amine used) and the obtained compound obtained hydrophobic character. Of the amines used was selected n-butylamine, n-hexylamine, n-octylamine, n-dodecylamine and n-octadecylamine. Hydrophobic amidated derivatives containing n-alkyl (C4 to C18) are able to function as sorbents nonpolar compounds and thereby decrease the in vivo levels of neutral sterols and triglycerides. Alginates are extracted from brown algae (Phaeophyceae) and have a wide industrial application. This procedure is a modification extends the possibility of recovery.

The technical solution adresses the generation of spark discharges. A significant application case is the formation of metal microparticles and nanoparticles. Another useful application is in case of pulse-controlled fluid flows such as control of the boundary layer formed on the surface of aircraft wings or turbine blades. Another fluidics application concerns the control of fluid flows formed at the outlet from a nozzle.\n

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

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.

Passive collector of solid occult precipitation was developed in order to assess the quality of occult precipitation especially from the wind driven fogs and low clouds during a winter season in the form of the rime. It is necessary to separate occult precipitation from falling precipitation (snow). The rime is collected on the construction of the collecting part of the passive collector of solid occult precipitation. The sample is collected as a mixture by (i) direct collection of the rime on the cartridge under the temperature conditions below zero, (ii) water collection from the rime melting. The rime from a collecting cartridge body is thus collected directly and/or it has been melting and gravitationally draining into the below laying funnel and then through a fine sieve to an instrumental box situated in the core body of the terminal console. The sample of water is accumulated in the chemically inert vessel protected against the evaporation and biological degradation for the purposes of the chemical analyses. Water is cumulated onto the impaction cartridge especially by the impaction, the instrument is fully self-governing independently on any source of electricity. The resistant robust construction of this new equipment was designed for the use on the top of the Czech mountains.

Technical solution concerns the composition of powdered additives in concrete, in contact safety additive photocatalytic self-cleaning and disinfection function.

Technical solution relates to the composition of a photocatalytically active cement screed for concrete, in which the screed ensures their self-cleaning and disinfecting properties.
