The present technical solution relates to cosmetic preparations containing triterpenes (especially betulin, betulinic acid, oleanonic acid, ursolic acid and / or lupeol), intended mainly for the cultivation / care of the scalp / hair, as well as topical lip care preparations and related preparations which bring a positive effect and relief in the event of herpes simplex or dental hygiene. The tritepene component is contained in the preparations in the form of a gel, which stabilizes it and thus does not precipitate or crystallize it.

The present invention is a device for the preparation of an asphalt mixture based on an eutectic mixture of plastics, particularly suitable for the additive of packaged mixtures for the construction of new pavements, the use of which can be solved by the above mentioned deficiencies, in particular by allowing the device to melt on the basis of microwave energy a mixture of waste plastics that subsequently binds themselves to create a final additive with a different softening temperature. Thus, the additive thus prepared is characterized by a different softening temperature, is bulk stable and sufficiently brittle to subsequently grind it. Additives prepared in this way are also suitable for mixtures containing recycled particles of old pavements as they increase their ratio in packed mixtures, thereby greatly reducing the cost of producing new pavements.

Beverage enriched with cane extract is prepared from grapevine juices or fruits juices and other beverages respectively to which an alcoholic extract of the grapevine cane containing trans-resveratrol and its oligomers, e.g., trans-epsilon-viniferin, is added. The resulting beverage has positive health effects.\n

Technical solution concerns the set-up for removal of heavy metals and metaloids of steams and off- gasses released by thermal desorption of organic materials from contaminated soils.

Y potato virus (PVY) is an important pathogen that reduces potato yields by 10 to 80% and reduces the market price of seed material. The subject of the utility model is that the primers are suitable for the specific diagnosis of this virus. The primers are derived from the Lukava RNA-dependent RNA polymerase gene (VIRUBRA 2/063) from the Potato Research Institute of Havlickuv Brod, s.r.o, and are capable of detecting virus in the leaves of infected plants using RT-LAMP.

Utility model concerns with the facility for the multi-stage gasification of carbonaceous fuels.

The utility model relates to the composition of an universal inorganic matrix on a geopolymer basis. into which it is possible to disperse selected powder additives. The resulting mixed materials are intended for the preparation of functional sacrificial materials, which, with their controlled composition, lead to more effective termination of severe nuclear reactor accidents.

The present invention relates to the rapid detection of the presence of a potato virus of the potato virus X, based on the amplification of a specific segment of the RNA-dependent RNA polymerase gene. The selected gene segment is derived from the PVX sequence in vector pGR106. The new primers are used, for example, in biotechnology for PVX detection in plant tissues.

Passive collector of liquid occult precipitation was developed in order to assess the quality of occult precipitation especially from the wind driven fogs and low clouds. It is necessary to separate occult precipitation from falling rain water. The impaction cartridge for the impaction and sedimentation of wind driven water droplets represents a fundamental part of this equipment. Collected water is then gravitationally drained into 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 by the processes of the impaction and sedimentation, 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.
