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 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.

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 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.

In addition to organic matter and nutrients, sewage sludge contains a variety of pollutants such as heavy metals, microplastics, pathogens, and a range of organic pollutants (PAHs, PAHs, per- and polyfluorinated atoms (PFAS), flame retardants, pharmaceuticals, hormones, or endocrine disruptors) (Husek et al., 2022). Their presence prevents or complicates their use on land and in the production of composts, which, due to environmental protection and precautionary principles, are no longer a sustainable way of disposing of this waste. Thermochemical methods represent an alternative. However, some distrust prevailed over pyrolysis, resulting from the lack of information on the ability to remove the organic pollutants present (Regulation (EU) 2019/1009, Huygens et al., 2019). Our work focused on studying PFAS and organic fluorine in sewage sludge and sludge-char (solid product produced after sludge pyrolysis). The obtained results serve to adjust already operating plants and to increase the knowledge of PFASs behaviour at different pyrolysis temperatures.

Marx’s Economic and Philosophical Manuscripts are usually interpreted as a transitional work between different elements of Feuerbach’s and Hegel’s philosophy which are still strongly present in the work of young Marx, and between Marx’s mature historical materialism. In the present text, we will try to show (with reference to the recent discussions on “young Marx”, especially in the French context), that the Manuscripts, in fact, contain an ontology that cannot be reduce either to a mere residuum of classical German philosophy, or to a materialist conception of social life. We shall try to describe this original ontology as an ontology of the sensible, or as an ontology of the finitude of human sensibility.”

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
