Abstract: Nowadays, people are exposed to noise on a daily basis. Therefore, in an overvibrant urban environments electrical vehicles operating at low speed are too quiet to be detected by pedestrians (especially vulnerable group are visually impaired people) and urban residents in general. Thus, electric vehicle warning sounds are sounds created to alert and warn pedestrians to the presence of electrical vehicles (e.g. hybrid electric vehicles, plug-in hybrid electric vehicles and all-electric vehicles) moving at low speeds. The goal of this paper is to determine through a case study what the pedestrians would desire and prefer the electrical vehicle warning audio signals to sound like. The case study involved 201 participants who had the task to fulfil a specially designed questionnaire for this purpose. Regarding the questionnaire, the participants were not prepared in any way for the testing they were just advised to keep in mind that the warning sound they select for the “role” of a pedestrian should not be irritable at the same time for the “role” of a driver. The results obtained from the questionnaire were analyzed and discussed in the paper. When speaking about the concept of smart cities and the legislation around the whole world today this is certainly a hot topic where the opinion of pedestrians and future drivers should not be overlooked.

Abstract: The subject of study and research of seismic artifacts, which include the study of abnormal seismic records is related to the history of tectonic development, fluid dynamic processes in the sedimentary cover interval, distribution of the thermobaric effects from formation fluid flow, upflow hydrocarbon migration and other features of the evolution of the Earth’s crust. On the territory of Western Siberia and the Kara Sea basin there is a wide development of abnormal forms of seismic record in the form of abnormal ring structures (ARS), also called inverted ring structures (IRS), fluid dynamic abnormities (FDA). ARS are vertically extended ring-shape of wave field deformation. The most complete study of the identified ARS by 3D seismic data. A lot of statistics data of such kind of abnormal antiforms accumulated at the present time. There are still many questions about cause and effect relationship of such artifacts with the secondary hydrocarbons migration mechanism, formation and accumulation hydrocarbon deposits, impact on vertical and lateral hydrocarbon migration intensity, the abnormal high pore pressures occurrence. One of the trends of seismic interpretation is studying of fluid dynamic abnormalities of seismic record and the relation with oil and gas potential in the sedimentary basin. In the article, the attempt is to establish to identify the correlation between various forms of fluid dynamic structures (FDS) with time and the stages of deep formation fluids migration occurrence. It is possible that the allocation of new types of hydrocarbon deposits of fluid dynamic type may be associated with ARS. It is still a hypothesis. But the presence and analysis of seismic attributes allow us to make this suggestion. What is positive is that all ARS studied by drilling related to the multi-bedded deposits. Identification and studying ARS patterns of relations with the mechanism of formation and accumulation hydrocarbon deposits allow us to conduct exploration geological prospecting works more efficiently, estimate correctly geological risks, rank and identify the most prospecting areas for exploratory drilling. The practice of prospecting of recent years has shown the accuracy and informatively of this trend as an indicator of petroleum potential.

Abstract: Depleted uranium (DU) has a beneficial use, such as ballast in aircraft and radiation shielding. Due to the chemical and radiological toxicity it may have adverse consequences to human health, particularly if it enters the body through inhalation, ingestion or wounding. One significant problem area, when working with DU, comes from finely divided airborne particles, which can result from some manufacturing operations such as machining and grinding. In this study RESRAD-Recycle computer code is used to estimate the exposure of workers and public to the recycling of scrap metal including depleted uranium and to evaluate the risk. Two general types of exposure scenarios have been incorporated into RESRAD-Recycle. The First scenario (worker scenario), evaluates worker’s doses during the recycled material process. The second scenario (product scenario), determines public dose and risk from the use or exposure to products made of contaminated scrap metal. The obtained results indicate that the slag worker exposed to the highest dose and risk. In addition, the produced products cause a public hazard. Therefore, strengthen the nuclear safety and security regulations to this material type is mandatory. Spreading safety, security and safeguard culture is requisite to reduce the hazards of the radioactive materials.
