Medical and sanitary issues on the Railways of Russia in 1917

The article is devoted to the issue of providing medical care to railway workers after the February revolution of 1917 in Russia. Social transformations of the revolutionary period also affected railway transport, affecting, among other things, the medical and sanitary issue. The purpose of the study was to study the changes that took place in the structure of medical and sanitary Affairs in railway transport in 1917. Since it existed before the February revolution of 1917 railway medicine could not satisfy the railway workers, and they considered the situation of medicine on the Railways abnormal. Railway workers clearly recognized the need for a radical reorganization of the formulation of railway medicine. They expressed their wishes that this issue should receive comprehensive coverage at the all-Russian Railway Congress, and that not only doctors, but also middle and Junior medical personnel of other categories (paramedics, midwives, pharmacists, disinfectants, etc.) should be invited to participate in the railway medicine section, as people who are closer and more familiar with the needs of railway workers. As a result of the research, the article shows that the all-Russian constituent railway Congress, held from July 15 to August 25, 1917, in Moscow, contributed to the formulation and progress of scientific and sanitary Affairs that served the interests of railway workers, taking into account the specifics of the revolutionary period.

Development of Solutions for Chemical Phosphating of Carbon Steel

A consumer in Uzbekistan imports concentrates phosphating the surface of carbon steels, such as, for example, Foscon 35 and Foscon 35K. (Russia). Work has been done to create analogs from local raw materials. Having studied the physicochemical properties of the concentrates, a mechanism for the formation of protective phosphate coatings was suggested, and the components of a new phosphating composition were selected. The aim of the work was to develop a composition of a solution for chemical phosphating of the surface of carbon steel at the local resource base. Methods used: elemental chemical analysis, electrochemical and corrosion measurements, conditionally total acidity of solutions was measured according to TU 2149-205-10964029-2004 (Russia). The effect of temperature, pH of the medium, and the exposure time of the sample in the phosphating solution on the quality of the phosphate film was studied. As a result, a phosphating composition FK-1 was developed, functionally similar to imported concentrates Foscon 35 and Foscon 35K, based on local raw materials.

Compound sentences and syntaxic predicative contructions

The article highlights the problem of compound sentences in the Turkic languages. Within the framework of this study, the problem of predicativity in complex sentences and the relationship of theoretical linguistics to predicative constructions used instead of a sentence member are investigated. A complex sentence, like a simple sentence, is pronounced with a single intonation, expressing a complete idea. Complex sentences describe more complex phenomena of the world around us than in simple sentences, and therefore these constructions appear as a later, higher expression of human speech. In primitive human speech, to express his feelings or other information, a person mainly used simple sentences. Later, as the connection between events became clearer, their expression in speech became more complex. Although simple sentences as components of a complex sentence, while maintaining intonation, are predicative parts of a certain syntactic construction.

Method of Extraction of Cadmium from Waste Cadmium Calcium Phosphate Catalyst

JSC "NAVOIYAZOT" in the process of producing acetaldehyde uses the catalyst "Catalyst cadmium-calcium-phosphate (CCP-N)" TU 113-03-00209510-108-2006, at a temperature of 340-350 ° C and a pressure of 0.2- 5-0.7 atm. Its service life is 6 months, after which it must be replaced and stored. Meanwhile, it is a potential raw material for the synthesis of a new catalyst. Due to the toxicity of the component, there are practically no publications on the topic of its recycling, processing and production of CCP-N are highly specialized. However, the authors had previously managed to independently solve this problem, a necessary stage of their research was the testing of their own development in production - in JSC "NAVOIYAZOT". Purpose of the work: testing the developed method for extracting cadmium from spent cadmium-calcium-phosphate catalyst. The cadmium recovered from the spent CCP-N catalyst was sorbed on the C-100 Purolite resin. Control of the content of components: СdO, CaO, and Р2О5 was carried out on an ICP spectrometer Aligent 7500 IСP MS. Information was obtained on the yield of the product of processing the solubility of CCP-N, the efficiency of the selected precipitant of cadmium ions, and their sorption on the C-100 Purolite resin. The test result is positive. The effectiveness of the developed method for extracting cadmium was confirmed, with the registration of an application for a patent for it.
