Abstract

The article considers application of an integral indicator of industrial safety in relation to hazardous production facilities (HPF) of ferrous and nonferrous metals processing in the Rostov region. The integral indicator is determined on the basis of individual indicators used to assess the probability of potential negative consequences of non-compliance with the requirements in the field of industrial safety.

Abstract

In the article, the authors conduct research on the assessment and control of hazards in the area of steel ropes splicing. The obtained results made it possible to clarify the reasons for the formation of dangerous factors such as: "undulation", wire strands breaks and loss of diameter of the steel rope. The main reason for the occurrence of dangerous factors is the uneven loading of wires and strands in the cross section of the steel rope. With the existing manual method of jointing, it is technologically impossible to ensure the uniformity of loading of all tucked strands, due to errors occur-ring on the length of each tucked strand, which directly depends on the human factor (experience and professionalism of the splicer) in the course of work. The authors propose a new method of jointing steel ropes using a polymer core, which is a conductor, which allows to exclude the hu-man factor and to keep in place of jointing the permissible values of defective indicators by diameter.

Abstract

The article considers the question of assessment of professional risk of workers. The analysis of conditions and safety of work in production of construction materials is carried out. The method of assessment of professional risk on the basis of integrated indicators of conditions and safety of work is offered. Interpretation of characteristics of working conditions on indicators of qualitative and quantitative standard of professional risk is given. Calculation of professional risk for the former of reinforced concrete structures is presented.

Abstract

The objective of this article is to create and train an artificial neural network based on a data set containing various climatic parameters and future fire area as an output parameter that the authors intend to predict. Such a “set” of data is usually available for research and study. Before training the neural network model, the data set is divided into two samples: a sample for training, which is about 90% of the set; and a sample for testing the trained model. In setting the task, the authors select and analyze the known data on the fires that occurred in Montesinho Park, compare the models trained on these data with and without normalization. As a result, two examples are given of a qualitative demonstration of graphs of absolute error changes of fire areas, which are projected using the created and trained model.

Abstract

The paper deals with the legal aspect of the problem of waters pollution of the Caspian Sea and further consequences. Modern ecological problems of the Caspian Sea are specified. Various normative legal acts are studied in detail; violations of both the norms of Russian law and international law are investigated.

Abstract

This article studies ecological problems of the Temernik, located within the boundaries of the residential area "Severny" of Rostov-on-Don. Nowadays the river is under the threat of disappearance. The authors analyze water hydrochemical indicators using short-term tests and compare it with normative requirements for water-quality of fishing water bodies. Water samples were taken in different places of the river with the total length of 2.8 km.
