   A study was made of the separation of an oil-water emulsion by polysulfonamide membranes with a cut-off particle mass of 20 kDa, treated with low-temperature high-frequency low-pressure capacitive plasma in air at a voltage Ua = 1.5–7.5 kV and treatment time τ = 1.5–7 min. Round flat filter elements with a diameter of 47 mm were used as membranes. The emulsion with a concentration of 3 % (by volume) was prepared on the basis of the Devonian oil of the Tumutukskoye field and distilled water, stabilized by a surfactant of the Kosintol-242 brand. The experiments were carried out on a laboratory ultrafiltration separation unit.

   The development of the Arctic, which has huge natural resources, is currently a priority for the Russian Federation. Economic research activities in the Russian Arctic zone are primarily associated with the search for mineral deposits and their further exploitation. However, it is necessary to take care in advance that the uniqueness of its natural and climatic landscape is not violated. The article presents ways to reduce the negative impact on the environment, analyzes the possibility of transferring large fleets of equipment (quarry dump trucks) to gas motor fuel, describes the structure of the developed simulation model for the delivery of ore by mining dump trucks to mining and processing plants in the Arctic when switching to gas motor fuel and calculates the optimal size of the fleet with its use.

It discusses their unique features and capabilities, and provides instructions and resources for beginners. The article also touches on problems in this area and ongoing research. As quantum computing continues to advance, programming languages will play an important role in unlocking the potential of these powerful systems.

   The article discusses an approach in which the spark plug was improved in 2 ways: by drilling a hole from the external L-shaped electrode of a conventional classic spark plug and cutting out the external electrode, and by installing a spacer in the fork of the Laval nozzle. In road tests, when using a spark plug with a Laval nozzle, fuel consumption was reduced by 1.38 times and the amount of carbon monoxide CO in the exhaust gases by 2.10 times.

   One of the many problems associated with environmental pollution is traffic flow. Within city 1, a car converts oxygen into carbon dioxide equal to the breath of 350-400 people, emits 900 kg of carbon monoxide, 50 kg of nitrogen oxide and more than 250 kg of various hydrocarbons into the atmosphere. The most toxic of them is carbon monoxide (CO), whose concentration in urban air is on average 16.08 mg/m³.

   The article shows the result of a research of reducing the output of defective products by quality control using the statistical process control (SPC). According to the results of the research, it was found that the bolt production process is not under control. The ways of eliminating the most frequent defect are considered, using a diagram of causes and effects.

   Modern software development methodologies involve close communication of the development team and the exchange of large arrays of heterogeneous data. In both cases, the use of various visualization methods, both processes and solutions, will greatly simplify communication and increase the efficiency and quality of development. This article focuses on the difficulty of choosing a suitable software solution for working with data and visualizing them due to the shortcomings of existing services. In the first part of the article, criteria for evaluating software solutions are proposed and a set of popular services selected for comparative analysis is determined, namely: Scrintal, Miro, Trello, Notion and YouTrack. The second part of the article discusses the advantages of diagrammatic representation of records over lists and analyzes the support for such representation in the services considered. The third part of the article summarizes the results of comparing services, identifies common problems and shortcomings in their functionality from the point of view of data visualization. In general, the article contains the results of a detailed comparative analysis of existing software solutions for working with data and their visualization.

   The essence of the Mobility-as-a-Service (MaaS) concept is to put the user at the center of transport services and offer him a personalized transportation option based on individual needs. MaaS combines all modes of transport with different modes of transport into a single carrier service available on demand. The service is provided through a single account with monthly payment. Since public transport is the core of the MaaS system, to implement the MaaS system of urban quality public transport services so that users can freely move around the city without owning a car, the following conditions are necessary: various types of urban public transport; many transport operators open their data, including real-time data, to third parties, and also allow third parties to sell their services; many transport operators support an electronic payment system to access their services.

   Тhe degree of contamination of the soil selected was determined in the forest park area of Naberezhnye Chelny, вased on the studies performed on the effect of industrial coolant PMK-205, as a pollutant, on the growth of the test object Lepidium sativum (watercress). The data on the germination of watercress seeds in the studied soil samples indicate the stimulating effect of coolant in all studied concentrations, that can be considered as its severe pollution according to the soil pollution assessment scale. It was shown the influence of coolant on the statistical and morphological parameters of sprouts is shown as a soil contaminant.

   Nanofiltration membranes were used to separate a gas-air mixture containing organic compounds. The membrane was obtained on a substrate of filter paper by watering with a three-component polymer solution. The surface layers were applied to the substrate by sequentially alternating the drying steps of the membrane. The retention capacity of the membranes was investigated by separating model gasoline-air mixtures. The average retention capacity of the membranes obtained was close to 90 %, and more than 90 % for aromatic compounds.

   Within the framework of the presented work, the possibility of using the leaf litter of urban anthropogenic landscapes for the sorption purification of aquatic environments from oil products was studied. Leaf litter of aspen (lat. Populustremula), maple (lat. Acer), birch (lat. Bétula), and apple (lat. Mālus) were selected as potential sorption materials. The physicochemical properties of the studied samples were determined. To assess the safety of use as a sorption material, an atomic emission determination of the content of mobile elements in foliage samples was carried out. It has been established that the content of heavy metal ions in ammonium acetate extracts does not exceed the established regulatory requirements, accordingly, the materials in question can be used as sorption materials. Under static and dynamic conditions, experiments were carried out to purify model solutions containing petroleum products. It has been established that all the samples under consideration to some extent have sorption properties with respect to petroleum products: the minimum adsorption capacity of maple leaves is 0.21 mg/g under static and 0.08 mg/g under dynamic conditions, the maximum adsorption capacity of leaves birch - 0.48and 0.17 mg/g, respectively.
