AbstractFor the third-order differential equationy′″ = ƒ(t, y, y′, y″), where, questions involving ‘uniqueness implies uniqueness’, ‘uniqueness implies existence’ and ‘optimal length subintervals of (a, b) on which solutions are unique’ are studied for a class of two-point boundary-value problems.

The article presents the results of research on the determination of rational technological parameters for the production of culinary products using dry mixtures and emulsions based on animal raw materials for additive technologies. It was found that when making products using mixtures and emulsions based on broiler chicken meat, as well as a combination of broiler chicken meat and pork, pork and beef (ratio 1:1) rational height of the layer, which makes it possible to ensure stability and safety of the product shape (with a fixed diameter of the opening of the culinary syringe – 7 mm and the optimal length of the layer - 100 mm), is from 14–21 mm (with a layer width of 7 mm) and up to 133–154 mm (with a layer width of 98 mm), which allows for improved structural and mechanical (SSL – 1090.7–1099.9 Pa) and functional and technological indicators of these products (WHC – 92.7–97.5%). The rational sequence of application and the duration of chopping of the main and auxiliary raw materials for the manufacture of emulsions, the duration of preparation (3 minutes), the degree of hydration (1:2 – 1:3) and the temperature of water for the reduction of dry mixtures (60±1° C) were established, which made it possible to develop technological schemes for the production of culinary products using additive technologies.

Many derivatives of 2,3-dim ethoxy-4-hydroxypyridine, which were designed from examination of the structure-activity relationship of piericidins, were tested for inhibition of NADH-UQ reductase. The lipophilic side chain of those compounds was indicated to be a key part for activity and its optimal length was conjectured. By the use of two different phases of assay material, intact mitochondria and submitochondria, the size of a membrane effect was shown to depend on the structure of the side chain. 4-Hydroxyquinoline derivatives were also tested for an analogous role in relation to the electron transport function of menaquinone, and they were proven to be inhibitors of NADH-UQ reductase as good as the pyridine derivatives.
