This article deals with the ecological impacts of chemical substances that are found in the structure of Diesel engine exhaust gases and provides an overview of legislation that limits their maximum allowable emissions. Special consideration is given to the previously mostly neglected negative impact of particulate matter compared to the impact of carbon dioxide. Negative impact of particulates is especially noted as direct negative impact on human health whereby the expenses associated with medical treatment exceed the financial savings resulting from the usage of Diesel powered vehicles. Therefore, the paper presents the knowledge acquired through previous scientific research in the economically most developed countries, as well as the tendencies for the reduction of negative impacts of Diesel exhaust gases.

The article discusses topical issues and problems of the impact of industrial road transport on the environment, namely: emissions of pollutants into the atmosphere depending on the type of fuel and their negative impact on human health. The significant increase in the vehicle fleet is causing great harm in the form of harmful emissions from fuel combustion systems, which cannot be dealt with standard car cleaning systems. The situation is aggravated by the fact that car emissions are concentrated in the surface air layer - precisely in the zone of our breathing. Low- quality gasoline is still used, polluting the environment. About 280 harmful substances were found in the exhaust gases of cars, including carcinogenic benzopyrenes, nitrogen oxides, lead, mercury, aldehydes, carbon oxides, soot, hydrocarbons. These emissions increase significantly when starting off or increasing speed. Diesel engine emissions are different from gasoline engine emissions. A diesel engine burns fuel more completely, oxidizes less carbon and produces less non-combustible hydrocarbons. But, at the same time, due to the lack of air in the diesel engine, more nitrogen oxide is formed. Diesel engines also emit soot. Gas emissions from transport into the atmosphere are exposed to sunlight, which leads to photochemical reactions leading to the formation of NО2, 0з, peroxides, benzopyrene (C22H14) and other compounds. In addition, each vehicle emits rubber dust into the atmosphere when its tires are abraded and worn out. Accordingly, the scale of damage caused by transport to the environment and people is also increasing. The article analyzes the existing and promising types of fuel and the reduction of the technogenic impact of industrial road transport on the environment in Ukraine.

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.

Drawing from the negative impacts of the perception of organizational politics (POP) on the literature on organizational outcomes, the model proposed in this study examines a nonlinear relationship of POP on job satisfaction. In a similar way, ingratiation as a moderator variable is tested. Based on a survey of 240 state-owned enterprise employees in Indonesia, this study finds that POP exhibits an inverted U-shaped relationship with job satisfaction. Low and high levels of POP have a negative impact on job satisfaction. Nevertheless, our most intriguing finding is that ingratiation behavior not only strengthens POP’s effects on job satisfaction, but can also alter the direction of the relationship in which its shape is represented by a U-shape. This shape indicates that the employees who engage in high levels of ingratiation as a coping mechanism and adaptive strategy tend to do so when they perceive high degrees of POP. These results are then discussed from a cross-cultural perspective as an attempt to explain the legitimacy of ingratiation in Indonesia.

This study examines the relationship between terrorism and economic openness that takes into account both the number and intensity of terrorist incidents and the impact of government military expenditures on trade-GDP and foreign direct investment-GDP ratios for both developed and developing countries. It uses the dynamic GMM method to account for endogeneity in the variables. Deaths caused by terrorism have a significant negative impact on FDI flows, and the number of terrorist attacks is also found to be significant in hampering the countries’ ability to trade with other nations. The study also demonstrates that the developing countries exhibit almost similar results to our main analysis. The developed countries exhibit a negative impact of terrorism, but the regression results are not significant.

The current study was heading for determining the impact of Pakistani university students’ socioeconomic classes on their personality traits. Demographic and personality questionnaires were filled by available university students online. The stepwise regression technique facilitated to generate regression models to define impacts of different socioeconomic classes on students’ different personality traits. Different regression models highlighted the significant negative impacts of the middle upper socioeconomic class on Agreeableness, Extraversion and Neuroticism personality traits. The lower socioeconomic class was found to have positive impact on only one personality sub-trait self-discipline. Whereas, the upper lower socioeconomic class caused positive impacts on students’ trust sub-trait, Conscientiousness trait and negative impact on excitement seeking sub-trait of personality. The importance of these impacts of socioeconomic classes on different personality traits and the possible implications are discussed with respect to university students’ academic performance and academic behaviour.

Technology is developing very rapidly so that it can simplify human work, both science, information, games, buying and selling, and so on on the internet. Apart from having an impact on the fast and easy access to information, it also has an impact on health, social, intelligence, psychological, financial and other aspects. It is excessive if it is overused to make it addictive. Such as addiction to online games, TikTok, and youtube which results in dependence and underestimates health and time. This research uses literacy studies. The purpose of this study is to present findings of the impact of gadget use on children. The results show that technological advances have both positive and negative impacts. There are various kinds of game applications that are easily accessed by children, both game content and those that can stimulate children's development, such as creativity, memory, physical motor, cognitive and so on. So it is necessary to take preventive steps so that technological developments can also reduce the negative impact on children's development.
