This article analyzes and reviews modern methods and technologies used in anti-plagiarism systems, with an emphasis on the Russian market. The purpose of considering all of the above is to choose a suitable anti-plagiarism system for integration. The article presents the most popular Russian services for detecting borrowings, their business models, algorithms of operation, as well as a general description of the principles and mechanisms underlying these algorithms. It was determined that the most universal and effective system for finding loans is the service Antiplagiat.ru , since it has the possibility of integration via the API, as well as 34 additional modules that provide the opportunity to adapt the functionality of the system to individual needs.

Keywords: antiplagiarism, text analysis, text processing algorithms, semantic analysis, stylistic analysis

The article deals with some of the most common waste from the construction industry. These are waste generated as a result of the construction of buildings and structures, concrete scrap. At the moment in Moscow in 2018, a programme of renovation, demolition of old housing, which estimates the amount of concrete scrap will amount to more than 14 million m3. The most effective way of recycling is using waste concrete scrap including eliminations of crushing in the manufacture of concrete. The problems of processing concrete scrap associated with the accumulation of a large number of screenings of concrete scrap, which is actually not used anywhere, are considered. Their number increases very much every year. As a result of the study, the chemical and mineralogical composition of ground concrete scrap was determined, as well as the grinding was performed up to Sud = 500 m2/kg. The possibility of using these ground wastes of concrete scrap (MOBL) as an active mineral additive (AMA) for the production of cement-sand solutions is considered. Due to the significant content of silica in these wastes in crystalline and amorphous form, these wastes can be classified as silica-containing. The kinetics of hardening of cement-sand solutions using active mineral additive was studied, histograms were constructed and conclusions were formulated.

The article analyzes the sources of waste in the Rostov region, namely the accumulation of toxic chemicals, household activities of the population, the fuel and energy complex. As a result of violations of waste disposal technologies is a high level of air pollution, water pollution, soil degradation, soil and water contamination by heavy metals, spontaneous combustion of landfill biogas allocation.      Consider measures to ensure environmental safety in the Rostov region ""for 2014 - 2020 g provided a long-term regional target program of 2,012m
