Modeling of "groove" rolling defect on internal surface of pipes at lengthwise rolling

The research has been conducted in pipe forming at rolling off by lengthwise rolling mill with stub mandrel; the patterns of change in dimensionless parameters were determined, which characterize deformation in side angle depending on http://www.multitran.ru/c/m.exe?t=424995_2_1elongation ratio. The model of formation of lengthwise groove on internal surface of pipes has been proposed

DECOLOURATION WITH ASCORBIC ACID UNDER EXTERNAL INFLUENCES OF METHYLENE BLUE

The present work is devoted to the study of the enzymatic activity of thiazine dyes under external action. Discoloration of methylene blue with ascorbic acid under external infl-ence. Experimental data are obtained for the dependence of the decolorization reaction rate on the mixing rate

STUDY OF THE INFLUENCE OF LOW-FREQUENCY AXIAL IMPACT ON THE RATE OF METHYLENE BLUE DECOLORIZATION BY SODIUM THIOSULPHATE

This article presents the results of a study of a low-frequency acoustic field in the fre-quency range from 10 to 100 Hz on the redox reaction of a thiazine dye methylene blue with sodium thiosulfate. The effect of frequency on the process of dye decolorization was deter-mined.Исследование выполнено при финансовой поддержке РФФИ в рамках научного про-екта № 20-33-90152.The reported study was funded by RFBR, project number 20-33-90152

STUDY OF A RESOURCE-SAVING METHOD FOR THE FINELY DISPERSED CALCIUM CARBONATE SYNTHESIS

The presented work relates to the studying the mass transfer effect creating finely dispersed calcium carbonate in a low energy exposure field. The use of the studied exposure has been experimentally established to have a positive effect on the resulting calcium carbonate

INVESTIGATION OF THE SPECTRAL CHARACTERISTICS OF POLYVINYLPYRROLIDONE-IODINE IN THE FIELD OF LOW-FREQUENCY VIBROACOUSTIC OSCILLATIONS

The change in the optical density spectrum of povidone-iodine in the field of low-frequency oscillations was studied. A conclusion about the dissociation of the complex under the action of infrasound is made. Partially confirmed data on the structure of the complex

WATER PURIFICATION METHOD FROM IRON (II) IONS BY VIBROACOUSTIC ACTION MEANS

The paper considers the process of water purification from iron (II) ions by means of their oxidation using low-frequency vibroacoustic effects, as well as a comparison of this method with bubbling

Persistence of the Effect of Changing pH during Infrasonic Impact on Water

In the current article, experimental evidence of influence of low-frequency low-energy oscillations on change of hydrogen index of distilled water is presented. The phenomenon of system relaxation after acoustic influence is established. The hypothesis explaining this phenomenon has been proposed.The reported study was funded by RFBR, project number 20-33-90152.Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 20-33-90152
