The presence of a major repulsive ion-induced structural force or disjoining pressure between Ca-clay particles is demonstrated. This arises from the perturbation of the normal structure for water to distances of about 50 A. This force operates in slit-shaped pores between clay particles and is opposed principally by attractive ion-ion correlation forces in regions of clay particle overlap.

The article is devoted to the study of the peculiarities of the translation of terminology on the material of the English business discourse into Ukrainian and Chinese. The study represents the main approach to the definitions of such concepts as “business discourse” and “translation operation” in current language- and translational studies; the linguistic features of business discourse are analyzed; the translation operations applied at the lexical-semantic and structural component levels when translating English terms of business discourse into Ukrainian and Chinese are analyzed; the choice of translation operations when translating the terms of English discourse as a method of achieving an adequate translation. Key words: business discourse, translation operation, terminology, a term, the Chinese language.

Population’s satisfaction with medical care has recently become an important structural component of the comprehensive assessment of the healthcare activities. The satisfaction is subjectively determined which makes it possible to assess the level of the population’s satisfaction with medical care. The sociological survey is recognised as the most informative method of study. The article provides the results of study of satisfaction with medical care of the respondents suffering from chronic diseases and followed up at the medical institutions of Saratov that has been conducted by the authors.

Didymosphenia geminata diatoms, or Didymo, was first found to be an invasive species that could have negative impacts on the environment due to the aggressive growth of its polysaccharide-based stalks. The stalks’ adhesive properties have prompted park officials to alert the general public to limit further spread and contamination of this algae to other bodies of water. Although the negative effects of Didymo have been studied in the past, recent studies have demonstrated a potential positive side to this alga. One of the potential benefits includes the structural component of the polysaccharide stalks. The origin of the polysaccharides within stalks remains unknown; however, they can be useful in a waste management and agricultural setting. The primary purpose of this study was to describe both the harmful and beneficial nature of Didymo. Important outcomes include findings related to its application in various fields such as medicine and technology. These polysaccharides can be isolated and studied closely to produce efficient solar power cells and batteries. Though they may be harmful while uncontained in nature, they appear to be very useful in the technological and medical advancement of our society.
