Press in System of Bolshevik Propaganda during the Civil War in the North-West of Russia in 1919

The issues related to determining the place of the regional Bolshevik press in the system of propaganda activities of the Bolsheviks during the Civil War in the North-West of Russia in 1919 are discussed in the article. The relevance of the study is due to the significant role of the media in the regulation of socio-political processes both in modern Russia and in its historical past. The novelty of the study is in the consideration of the Bolshevik periodicals as a purposefully used by the "red" tool in achieving victory in the military-political confrontation with the White Guards. A comparative analysis of the materials of Bolshevik publications published in 1919 in the North-West of Russia was carried out. It is concluded that the press occupied an important place in the Bolshevik propaganda system in the northwestern region. It was established that its keynote was the formation of a negative image of the enemy in contrast with the Bolsheviks and the Red Army. It is proved that in the local Bolshevik press the image of "Soviet power" as the only fair and the Red Army as a powerful and invincible force was consistently created. It is shown that the positions and slogans put forward in the Bolshevik press were called upon to provide massive support for the revolutionary forces in the region and the mobilization of forces to repulse the enemy

Women Workers of St. Petersburg in the Late 19th — early 20th Centuries

The article is devoted to the analysis of the conditions of labor activity, as well as the peculiarities of family life and everyday life of women employed at the enterprises of the factory industry of St. Petersburg in the late 19th — early 20th centuries. At the present stage of development of Russia, there is still a high proportion of female labor in industry, which determines the relevance of the problem under study in order to take into account the historical experience in regulating the complex sphere of labor relations. The question of the main factors in the formation of the female labor force in St. Petersburg during the post-reform period is raised in the article. The industries in which female labor was most widely represented are identified. Issues related to the peculiarities of the professional activity of female workers (working conditions, level of wages, problems of social protection, etc.) are discussed in detail. The circumstances of private, personal life are analyzed, the influence of material factors in the life of workers on the family life is revealed. It is concluded that the contradictions between the new status of a woman, who is able to independently determine her own fate, and the preservation of her unequal position in society, led to the wide participation of women workers in the political life of St. Petersburg during the First World War and the 1917 revolution

Predicting Concentrations of Organic Chemicals in Fish by Using Toxicokinetic Models

Quantification of chemical toxicity continues to be generally based on measured external concentrations. Yet, internal chemical concentrations have been suggested to be a more suitable parameter. To better understand the relationship between the external and internal concentrations of chemicals in fish, and to quantify internal concentrations we compared three. toxicokinetic (TK) models with each other and with literature data of measured concentrations of 39 chemicals. Two one, compartment models, together with the physiologically based toxicokinetic (PBTK) model, in which we improved the treatment of lipids, were used to predict concentrations of organic chemicals in two fish species: rainbow trout (Oncorhynchus mykiss) and fathead minnow (Pimephales promelas). All models predicted the measured internal concentrations in fish within I order of magnitude for at least 68% of the chemicals. Furthermore, the PBTK model outperformed the one-compartment models with respect to simulating chemical concentrations in the whole body (at least 88% of internal concentrations were predicted within 1 order of magnitude using the PBTK model). All the models can be used to predict concentrations in different fish species without additional experiments. However, further development of TK models is required for polar, ionizable, and easily biotransformed compounds
