Here is offered a method of production of unburnt synthanite from natural minerals using apparatus with vortex layer of ferromagnetic particles. There was fulfilled comparative quality analyses of anhydrite binding substances, produced by anhydrite rock milling together with complex solidifying activator in traditional ball mills, and substances produced by our method. It was stated that achieved rising of the hydration activity of synthanite by collective milling of the raw material components was a result of ferromagnetic particles hindered impact under magnetic field influence. The reason for such activity is not only increase in specific surface area of the milling material, but changes in anhydrite structure at the crystalline grid level, preserving a lot of defects on the separate particle surface.

Oštiepok is a traditional half-fat semi-hard cheese made in Slovakia. The basic raw material used to produce oštiepok cheese is ewe's milk, a mixture of ewe's and cow's milk or cow's milk. Oštiepok cheese is produced either directly at a small-scale mountainside sheep farm, using the traditional on-farm method of production, or at dairies, using the industrial method. Oštiepok cheese was produced as far back as the beginning of the 18th century. An industrial production of Oštiepok cheese using cow's milk were laid by the Galbavý family in Detva (Slovakia) in 1921. The cheese is originally made by cutting off fresh sweet cheese, which is pressed into a wooden, hand-cut and decorated round shape where it is left to stand. Subsequently, it is removed and immersed in warm salty water, left to stand there until the salt penetrates completely in. Then it is necessary that it pass slightly. In its salty water, the ostrich produces its traditional durability, its surface is slightly peeled, mostly yellowish. This cheese may or may not be steamed and may be smoked or unsmoked. Slovenský oštiepok is a protected trade name under the EU's protected geographical indication. A similar cheese is made in the Polish Tatra Mountains under the name Oscypek. The cheeses differ in ingredients' ratios, cheesemaking process and the characteristics of the final products. In this study we have characterized textural and sensory properties of the Oštiepok cheese produced in Slovakia made from ewe's milk, a mixture of ewe's and cow's milk and cow's milk.

The use of biogas for the operation of recycling equipment in its pure form is unacceptable due to the high content of sulfur compounds (hydrogen sulfide), which leads to corrosion of metal parts of the equipment contacting with biogas and reduces its service life. The article considers various ways of cleaning biogas from sulfur compounds. (Research purpose) The research purpose is in studying the process of biogas purification from sulfur compounds by sulfonating in the vortex layer apparatus. (Materials and methods) The laboratory of bioenergetic and supercritical technologies of VIM created an experimental device of a vortex magnetic layer. Authors used information research methods, including standard analytical methods of modern system approach, processing and analysis. (Results and discussion) The amount of hydrogen sulfide in the biogas was sharply reduced and when the gas stayed in the working chamber for 5 minutes, it did not exceed 20 parts per million. The concentration of carbon dioxide decreased slightly. The water in the working chamber of the installation serves as a solvent for incoming gases, and the ferromagnetic particles, when worn out, form a fine (20-50 micrometers) iron powder, which reacts chemically with dissolved hydrogen sulfide to form iron sulfide. Fast-rotating ferromagnetic particles create a large contact surface of liquid and gas, which improves the absorption of hydrogen sulfide and carbon dioxide. (Conclusions) It is possible to purify biogas from sulfur compounds by sulfonating in the vortex layer apparatus. The article proposes a method for improving the cleaning process by increasing the pressure and reducing the temperature of water in the working chamber of the vortex layer apparatus.

Abstract Precious organic cultural relics are easily affected by temperature, humidity, and harmful gases in the environment, resulting in embrittlement, fading, mildew, moth damage and other aging forms. An energy-saving and environmentally friendly material is needed to stabilize humidity and adsorb harmful gases in the environment. In this paper, with an intelligent adjustment function, functional paper containing sepiolite and tourmaline natural minerals was successfully prepared. The component of 80 % of wingceltis and 20 % of straw in dry pulp as main raw material was conducive to the desorption of water molecules. As favorable structure inside functional paper, the adsorption point and the adsorption contact area increased by the rough surface of fiber bundles, the addition of sepiolite and the ordered molecular chains of copolymers destroyed. So, the relative humidity could be adjusted to 55 % ± 3 within 2 hours and was stable with functional paper. At the same time, 1.11 ppm sulfur dioxide and 2.98 ppm ammonia could be effectively adsorbed in 10 and 12 h, respectively, by 1 g of paper in a 5 L container. The pH of the paper was adjusted to neutral with tourmaline, even if the pH was changed by acidic or alkaline gas absorption. Therefore, for long-term organic cultural relic preservation, preparing a constant-humidity and clean environment is of great significance. This is possible through this paper.

Rhodiola rosae L., from the Crassulacea family, is a perennial widely known in Russian folk and official medicine for its adaptogenic properties. The extracts from the roots of Rhodiola rosae is known to be a better alternative to ginseng because of its better effects, safety for people having high blood pressure, cardiac and kidney problems, pregnancy, and minors. Rhodiola is collected mostly from the wild, and this practice has resulted in the decimation of the wild population in Altai mountains and in southern Siberia. The objective of this investigation was to find the best method of production and guarantee the availability of the raw material without compromising the quality. Plants were studied under naturally growing conditions and brought into cultivation. We used seeds to propagate. Morphological traits, flowering, leaf area, shoot and root yield, and content of salidroside (biologically active component in the root) were measured in 50 plants. The measurements were taken during the 1st, 2nd, and 3rd years of the cultivated plants, while parallel measurements were taken from the same place of naturally growing plants. Plants under natural conditions did not receive any agronomic treatment, while normal agronomic practices were given for plots under cultivation. We found significant difference an all measured parameters. Though higher root yield was obtained from cultivated plants, the concentration of salidroside was found to be higher naturally grown plants. With the increasing age of the cultivated plants, however, the concentration of salidroside significantly increased. The total yield of salidroside, g/m2 was found to increase consistently each year for cultivated variants compared to plots under natural growth.

This paper presents a comparative study of the adsorption activity of the grass meal of lady's mantle aerial part (Alchemilla vulgaris) and modern adsorption materials – activated carbon (carbolenum) and hydrolyzed lignin (polyphepane) towards model substances (markers of adsorption). The model substances were used to effectively simulate a group of toxic substances with different molar mass and degree of ionogenicity in the environment that simulates gastric and intestinal juices. It was shown that hydrolized lignin had the highest protein adsorption activity and activated carbon appeared the most active in sorbing toxicants with low molar mass. The grass meal of lady's mantle aerial parts (Alchemilla vulgaris) was able to moderately absorb both high-molar mass and low-molar mass substances at an average degree of dispersion of the raw material. It is supposed that it was mainly due to the high-porous structure of the material. This shows the versatility of the enterosorbent under development.

Pre Treatment

Post-harvest crop residues are an interesting raw material for the production of composite materials. However, their surface often contains waxy and siliceous substances, which can cause adhesion problems. Therefore, various surface pre-treatment methods have been developed to increase the surface tension of these particles and hence to improve adhesive adhesion. The influence of hydrothermal, chemical, plasma and enzymatic treatment was investigated. The aim of the paper is to evaluate the effect of pre-treatments of post-harvest crop residues on the nature of joint failure and adhesive dispersion on the particles. The evaluation is based on microscopic analysis of particles obtained from the rupture area after internal bonding tests. The nature of bond failure and adhesive dispersion on the particle surface is evaluated. The results show a clear influence of material pre-treatment on the failure bond of the bond and, to a large extent, correlate with the mechanical properties of composites published in previous studies. The most suitable treatment appears to be a plasma treatment at a properly adjusted intensity. Conversely, the unsuitable treatment was alkaline, which, although it increased adhesion, deteriorated the overall mechanical properties. Hydrothermal treatment could be also considered as an industrially suitable method.
