Kryvomaz, Julia Bereznitska","doi":"10.32557/USEFUL-2-4-2018-0002","DOIUrl":"https://doi.org/10.32557/USEFUL-2-4-2018-0002","url":null,"abstract":"The study is devoted to the estimation of pollution deposit caused by vehicles into the city to-tal greenhouse gases emissions and to the forecast of the secondary air pollution with formal-dehyde. \u0000The present study contains mathematic model which allows getting the estimation of vehicles emission in the total amount of polluted atmospheric air. The model consists of two intercon-nected parts: a dynamic and a kinetic one. The first part of the model is based on the Theory of Convective Jet and Thermals in the Atmosphere and allows to get the parameters of the contaminated air which is being formed over the highway. The Dynamic part of the model allows to get the total amount of hydrocarbons emission depending on the number of vehicles which is present at the same time on the highway. We also obtain the data on concentration of pollution and temperature increasing in the narrowest section of the thermal jet. \u0000The kinetic part of the model allows to determine the concentration of the secondary atmos-pheric air contamination with formaldehyde as a result of photochemical transformation of hydrocarbons which are the part of emission of internal combustion engine. The speed of the transformation reaction was determined by the Can't Hoff-Arrhenius deferential equation.\u0000The given mathematical model was tested with the help of the system of regular observation over the polluted atmospheric air in Kyiv city. The comparison of the estimated value of for-maldehyde concentration and the observation data doesn't exceed 5 % above the maximum values. According to average monthly rates there is a false positive error (to + 20 % in the warmest months). \u0000Basing on the given model the calculator of concentration of pollution by vehicles was devel-oped. This calculator allows to obtain rapidly the values of formaldehyde concentration, de-pending on air temperature, solar radiation and number of vehicles on the highway. The amount of hydrocarbon emission from the vehicles, according the suggested model, allows to estimate the deposit of vehicles into the total amount of greenhouse gases of the city. The ob-tained results could be useful in forming of ecological policy of the cities and in managerial decision making.","PeriodicalId":118526,"journal":{"name":"USEFUL online journal","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121438751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emergence of potentially possible conflict situations in the preparation of technical water under critical operating conditions of the TEO systems is investigated. It is established that there is a decrease in the total concentration of integral material evidence. It is shown that biological changes in the TEO systems are formed at the temperature (mode) - specific electrical conductivity of biological overgrowing, which is confirmed by the presence of \"wildlife\", which necessitates the identification and establishment of optimal gradations in relation to the operation of the TEO systems. Confirmation of this is the biotic potential in the operation of the feasibility study: for optimal regimes -1,7; under critical conditions - 2,6 (the self-organization of material flows is violated).","PeriodicalId":118526,"journal":{"name":"USEFUL online journal","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122643171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
