The aim of the study was to study the redox potential of aerosols in the residential area of the village. Kuporosny (Volgograd, Sovetsky district) (experimental area) in comparison with the conditionally clean zone. The objectives of the study were to select aerosol particles in the leaves of apricot trees (Prunus armeniaca L.); preparation of aerosol suspensions from the leaves of apricot trees; study of the ORP of aerosol suspensions when they are infused for 5 minutes in distilled water; discussion of the obtained results. Methods. Leaves of apricot trees (Prunus armeniaca L.) in the amount of 10 pcs. placed in a glass dish, added 100 ml. distilled water, stirred them for several minutes with a glass rod to wash the particles from the surface of the leaves.

"This article describes the application of the ontological approach to the creation of an intelligent system of recommendations in the work of military recruitment committee. A popular and perfectly proven approach to describe and represent knowledge is ontologies. Designing knowledge-based systems is impossible without a thorough systematic study of the subject area in which the problem is to be solved. The result of systems research should be represented by the formalism best adapted for further implementation. Ontology is such a formalism, and this article discusses approaches to the formal representation of ontologies as the most important mechanism of knowledge engineering. Conceptually, ontology design processes are similar to those with multi-agent systems. In this case, nodes or agents connected to each other materialize our knowledge of the problem solution. An agent is comparable to the notion of an entity in an ontology. In both cases, an ontology graph is used. The Protégé software platform was chosen as one of the most popular development tools to implement the ontology ""Military Recruitment Committee"". An important factor is the support of SWRL, which is necessary for the future development of the project. In the process of ontology design, three main branches of entities were identified: questionnaire data; medical data; psychological data. Based on the results of the logical inference, a recommendation (advice) is formed regarding further decisions (actions) on working with a conscript. The SWRL is used to create rules for checking the set of properties for each conscript, on which a verdict is made. If necessary, the system will explain its actions. As a result, a preliminary ontological graph of the investigated domain in the OWL language is made. Implemented some software modules. Conducted a logical inference on the Protégé platform based on the description in SWRL language of the rules reflecting the impact of the set of entities of the ontology on the inferred recommendations."

The most important task of the admissions committee of any university is to advise applicants on admission to the specialties available at the university. In this article, an automated information system has been developed, which, based on the applicant's questionnaire, allows you to form recommendations when choosing a training specialty, taking into account the applicant's personal preferences. Artificial neural networks are proposed to be used as a method of choice, and the multilayer perceptron (MLP) was the model of the neural network.

With the development of industry and science, the size of the patent base is growing, as well as the number of patent applications received by the agencies regulating the issue of patents is growing. Each patent application must be checked for the uniqueness of the patented technology, for this, the patent office experts need to search the patent database and find analog patents. In the absence of analog patents, this technology can be considered unique and accepted for patenting. Since the patent database of various departments can number tens of millions of patents, such a patent search and evaluation of the uniqueness of the patented technology can take a very long time. The existing systems do not meet all the requirements and do not have the full necessary functionality. This article describes the development of an automated system for searching for analog patents in the patent array.

During operation, the pipeline is threatened by various geological hazards, especially in regions with permafrost, where freeze-thaw disasters have a significant impact on the integrity and safety of oil and gas pipelines. Therefore, at the design and construction stage, it is advisable to analyze various methods of laying pipelines, taking into account the topographic environmental conditions, as well as the effect of frost rise and thaw on the soil of the pipeline foundation. An analysis of the existing design schemes for the construction of pipelines, the conditions for passing the route of the projected pipeline, the characteristics of the pumped hydrocarbons makes it possible to justify the choice of a construction method that can ensure the stable position of the oil and gas pipeline both during the construction period and during its operation.

The article considers internal adjustable sun-protecting jalousies from their different functional efficiency pant of view. It is noted, that besides their main sun-protective function, adjustable jalousies possess some other functions, depending on the position of their horizontal planks. These functions can be successfully used for microclimatic internal environment creation of comfortable. These are natural lighting function, psychological contract with surrounding environment function and function of visual isolation, i.e. “privacy”. and so on. All the above functions usually have maximum efficiency of their qualities in the case of their individual consideration. This, as a rule, is not practically reasonable. That is why this work is aimed on optimum combination of the man functional characteristics of horizontal sun-protecting jalousies under necessity of their mutual consideration, i.e. in achievement of their functional universality.
