Hydrodynamic features of suspensions and emulsions flows. [Текст] / S. R. Rasulov, G. R. Mustafayeva // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №2. - P. 99-104

Рубрики: Горное дело
Кл.слова (ненормированные):
hydrodynamics -- differential equation -- suspensions -- emulsions -- dispersed phase -- solid spherical particle -- turbulent flow -- pulsating motion
Аннотация: This scientific article is devoted to the problems associated with the flow of suspensions and emulsions and some simplifications of the real picture of the flow of a polydisperse medium are made. It is also stipulated that differential equations characterizing the motion of suspensions and emulsions should take into account the fundamental discontinuity of the medium and the physicochemical processes of heat and mass transfer occurring in it. Taking into account all these factors, a general equation for multiphase systems is proposed with certain simplifications that do not change.

Аннотация: In this article, the chemical composition of tubers and juice-semi-finished products from jerusalem artichoke is investigated. The results of the studies showed that the bulk of the dry substances in jerusalem artichoke tubers are carbohydrates, most of which are represented by fructosides. In the semi-finished juice passes: oligosaccharides 22.54 %, monosaccharides 1.61%, as well as part of the structural polysaccharides-fiber 0.07 %, pectin substances 1.84 %.

medicinal plants -- Taraxacum koksaghyz rodin -- biologically active substances -- flavonoids -- IR spectrum -- 13С -NMR
Аннотация: In recent years, the interest of researchers in the herbal preparation has grown significantly. Plants are sources of biologically active substances (BAS). In previous articles, the chemical composition and biologically active substances of plants endemic Taraxacum kok-saghyz Rodin growing in Kazakhstan has been studied. Among the BAS of plant origin, inulin and flavonoids occupy a special place. The article examines the release of inulin and flavonoid from the stem of Taraxacum kok-saghyz Rodin plants. In order to isolate a flavonoid, you first need to extract inulin. Due to the fact that in our plants, inulin accumulates up to 40%. Therefore, the first stage was to isolate inulin: with extractions 1:10 with distilled water for 60 minutes, and in the second stage, the further isolation of the residue was first dried, the dry residue was 1:10 with a ratio of 70% ethanol for 3 hours. The inulin yield was -5%, the melting point was 1300C. A The yield of flavanoid is 0.66%, the melting point is 1700 C, the aggregate state is acicular light brown light. The structure of the isolated flavonoid was determined on a Uviline 9100 spectro-photometer; the highest absorption was observed at a wavelength of 364 nm. Consequently, the structure of the isolated flavonoid coincides with the literature data. The maxima of the UV, IR, 13С -NMR. spectrum show that flavonol is a derivative.
