A method for the polymerization modification of nanoscale fumed silica by crosslinking a lignin layer adsorbed on a nanosilica surface under a gas dispersion medium is described. A mixture of phenol and formaldehyde in the presence of HCl proved to be the most effective crosslinking agent. It has been suggested that the crosslinking of lignin molecules occurs by a mechanism similar to the production of phenol-formaldehyde resins.

The main difference between mine waters, which makes it difficult to clean them, is the presence of finely dispersed (less than 10 microns) aggregate-resistant coal and rock particles, the amount of which can be 50-70% of the total mass of mechanical impurities. Suspended solids that are contained in mine water play a significant role in the contamination of nearby surface water bodies, since they either contain many chemical pollutants or adsorb heavy metals, which indicates the importance of effective mine water settling. Modeling of the mine water clarification process using an improved treatment technology for the conditions of wastewater disposal of an operating coal mining enterprise (Stepova mine of DTEK Pavlohradcoal Private Joint-Stock Company) through the introduction of a horizontal sedimentation tank of a modernized design was carried out. Dependences (in the form of graphs and regression equations) between the depth of particle settling depending on their the different hydraulic size in the proposed sedimentation tank of an improved design, its length and the efficiency of clarification of mine water after its treatment with a coagulant solution (aluminum sulfate) have been established. Using these dependencies, it is possible to determine the value of the expected efficiency of mine water clarification and the hydraulic particle size of suspended particles that can settle to the bottom at the end wall of the proposed sedimentation tank. The overall efficiency of mine water clarification, which is pumped to the surface by the Stepova mine, after treatment in a modernized sedimentation tank and post-treatment in a mine water storage pond, will be 90-91% of the initial concentration of suspended solids. The final concentration of mechanical impurities after treatment according to the proposed improved technology does not exceed the maximum allowable standard for water bodies for cultural and community purposes in terms of the content of suspended solids.

Wielogodzinne, wymuszone pozycje statyczne związane z pracą zawodową czy procesem edukacyjnym doprowadzają do przeciążeń kręgosłupa. Konsekwencją przeciążeń są zaburzenia funkcji kręgosłupa oraz zmiany strukturalne tkanek występujących w jego okolicy. Zmianom tym często towarzyszy ból. Złożona biomechanika kręgosłupa oraz różnorodność tkanek funkcjonalnie z nim związanych, stanowi istotny problem diagnostyczny. Metoda McKenzie poprzez opracowany model badania oparty na wywiadzie i badaniu przedmiotowym, pozwala wyodrębnić pacjentów o jednorodnym zaburzeniu narządu ruchu. Na jego podstawie zdiagnozować można mechaniczne źródło pochodzenia objawów oraz określić strukturę, która je generuje. W pracy opisano przypadek 26-letniego mężczyzny z bólem karku i kręczem prawostronnym, który został poddany terapii mechanicznej, poprzedzonej diagnozowaniem mechanicznym, w wyniku którego stwierdzono wystąpienie zespołu zaburzeń strukturalnych. Słowa kluczowe: kręcz karku, terapia mechaniczna, MCS Zebris. Abstract Pain occurring in the neck are common phenomenon. Forced, static and lasting many hours positions associated with work or educational process lead to overloading of the spine. Disorders of the spine function and structural changes of adjoining issue are the consequence of overloading. These changes are often associated by pain. The highly complicated spine biomechanics and a variety of functionally related tissues are an important diagnostic problem. McKenzie method allows to specify patients with homogeneous musculoskeletal disorder through elaborated diagnostic procedure based on an interview and physical examination. Mechanical cause of symptoms and structure that generates it can be identify based on it. This paper describes the case of 26-year-old man with neck pain and right torticollis, which has been submited to a mechanical treatment, preceded by a mechanical diagnosis, which concluded the complex of structural disorders. Key words: torticollis, mechanical treatment, MCS Zebris.
