Instruments of marketing management and techniques of credit supp ort should be aimed at providing sustainable development of large industrial enterprises as well as at creation of effective systems of corporate governance on the basis of integration of service and knowledge-based technologies. Development of industrial technologies and modernization of financial services assumes formation and improvement of adaptable marketing model of technological development of the industrial policy. It is also considered to be aimed at technological development of large industrial companies which demand of credit and finance and organizational support in current economic, institutional and geopolitical context in Russia.
Ground vehicles are the main sources of noise and infrasounds in residential areas. Numerous published works are devoted to the studies of audible sound, its sources in vehicle, and development of measures to its reduction. The authors believe that the problem of infrasound occurrence and propagation in residential areas and-hence-its negative impact on humans and ambient environment is underestimated. Development of predictions and experimental methods of studying the infrasound generating mechanism and environmental monitoring of this negative factor are an urgent issue. A significant portion of acoustic emission from a vehicle comprises infrasound and low frequency range. Internal and external infrasound of vehicle were measured. A prediction model was proposed and the influence of vehicle design features on the infrasound level was estimated. Predictions of the external infrasound generating the mechanism of vehicles reveal that its frequency and level depend on driving speed, drag coefficient, vehicle body length, and Strouhal number Wheels, which execute rotation and progressive movement in airstream, are important sources of vehicle infrasound. Five wheel harmonics were calculated for motor vehicles at various driving speeds, the existing dependences are detected. It was demonstrated that the regulatory levels of infrasound can be exceeded only in residential areas adjacent to traffic flow with driving speeds higher than 80 km/h. The results of field studies of infrasound level on the streets of Moscow were presented. Recommendations on the development of environmental monitoring and main approaches to reduce infrasound in urban environment were given.

В настоящее время при оценке негативного воздействия на окружающую среду не учитывается пылевыделение при проезде автомобильного транспорта по дорожным покрытиям различных типов. Наибольшую опасность для здоровья населения представляют мелкодисперсные частицы размером PM 2,5 и PM 10. Проблема расчета, контроля и нормирования выбросов мелкодисперсной пыли при проезде автотранспорта является важной для улучшения качества жизни и здоровья граждан, качества воздуха рабочих зон на предприятиях и внедрения перспективных технологий по снижению негативного воздействия источников пылевыделения на воздушную среду городов. В данной работе в ходе проведения предварительных оценок воздействия пыления автомобилей на окружающую среду были проведены инструментальные измерения и получены максимально-разовые и среднесуточные значения концентраций взвешенных веществ РМ 2,5 и РМ 10 в атмосферном воздухе.
There is a risk to human health when eating agricultural products grown on soils contaminated with heavy metals. Currently, the monitoring of soil contamination with toxicants of industrial origin. This study is devoted to the analysis of information support and published official statistical data on soil pollution in the Moscow region, where the share of agricultural land accounts for 1,750. 5 thousand hectares, which corresponds to 38.22% of the region’s territory. The study revealed certain shortcomings in the presentation of information on soil pollution, insufficient statistical data for the full implementation of environmental monitoring tasks, an increase in soil pollution with some heavy metals, etc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
