Abstract:

The paper develops the concept of the existence geodynamically dangerous zones in the earth’s crust. These zones affects to the safety of the state of engineering structures and mining operations. The concept of geodynamic zoning is used, according to which geodynamically dangerous zones occurs during the interaction of blocks of the earth’s crust of various hierarchical ranks. On the example of the East Donbass, the typification of the intersection of coal waste dumps with geodynamically dangerous zones is considered. The position of 34 burning and burnt out dumps located near the cities of S

Abstract:

With the development of deep coal resources, rockburst, as a kind of typical underground dynamic disaster, always threats the production safety. Before the mining design, it is very necessary to forecast the possibility of the rockburst. This paper takes the Guo-tun coal mine for the object, considering the specific geological conditions, to predict the possible dangerous area where rockburst would happen. Through the comprehensive research and analysis, the paper would divide the 1312 working face into some probalble dangerous zones, namely strong shock hazard zones and medium dangerous impac

The analysis of heavy metals and arsenic contamination of soils of the urbanized territory of Svirsk (Irkutsk region) is presented. The features of distribution and concentration of mobile forms of elements – toxicants in soils of different functional zones of the city are revealed. It has been established that the main pollutants of the soils of Svirsk are As, Zn, Pb, Cr, Fe and Cd, which have high accumulation rates. Mainly high–contrast polyelement geochemical anomalies Fe–Pb–As–Zn– Cd–Mn and Cu with extremely dangerous pollution levels are formed in the soil cover of industrial zones. The

Dance balls, masquerades, and street carnivals functioned as frontier spaces of otherwise reprehensible encounters between people of different gender, race, and class. I examine dance as a dense point of contact in nineteenth-century Cuba by showing how dance served ruling elites as a disciplining instrument to enforce social and legal boundaries, and was simultaneously used by colonial subjects as a tactic of survival to navigate these barriers. Because dancing lent itself to situations of intimacy and mis-recognition, it challenged Cuban ruling elites’ efforts to police dancing bodies. Dance

Toxic gas leakage has diffusion characteristics and thus dynamically affects surrounding zones.

However, the toxic gas propagation direction is not considered, and this may lead some evacuees driving from less dangerous regions to higher dangerous regions.

Modern climatic changes have an impact on the bearing capacity of permafrost soils at the base of the foundations of buildings and structures in the urbanized territories of the Arctic and Subarctic.

Based on the results for the geothermy of frozen and thawing soil, and on the georadar profiling of the city of Anadyr, it was concluded that the main risks of permafrost degradation are associated with the spread of hydrogenic melting zones.

Until the beginning of June 2020, the COVID-19 virus has spread to more than 215 countries, infected more than 6 million people and killed more than 300,000 people in the world. This causes public panic and misperceptions about COVID-19. Under circumstances like this, risk communication is needed to control and mitigate information about this plague to reduce the spread of this disease and manage public fear. The main objective of this study is to assess COVID-19 information searching behaviour and explore how risk communication is associated with personal hygiene habits in preventing transmis

Abstract:

Java Island is an island with a high earthquake vulnerability. Therefore, earthquake mitigation measures are needed to reduce the impact of earthquakes. Earthquake mitigation is done by knowing the zones with a high risk of earthquakes and high levels of rock stress. The methods used to map earthquake-prone zones are K-means clustering and B-value. The K means clustering method can provide earthquake clusters based on their characteristics and the B-value can produce rock stress conditions in the area. The results of this study are that the K-means clustering method produces 7 earthquake clust

Abstract In recent times multi-storied urban constructions require no-column space due to several reasons such as space, population, and aesthetic requirements. Especially by placing floating columns at baselevel provide us column free space for parking and free movement of vehicles. These structures often have floating columns, which can be dangerous in actives seismic zones. This study examines the detrimental impacts of floating columns in multi-storey buildings using construction sequence analysis (CSA) in different seismic zones as prescribed in Indian standard code of practice.

To establish the symptoms of pathogens of fomose rot on potato varieties of different resistance, to isolate pathogens from the genus Phoma, parasitizing on tubers and stems of plants. Methods. Symptoms of phomotic rot were determined visually by the determinant of diseases and the method of microbiological diagnosis was used. Pathogens were isolated from stems and tubers affected by fomose rot. Results. On the basis of psychopathological examination, it was experimentally proved for the first time in Ukraine that fomozna potato rot is widespread in commodity and seed potato

Based on the obtained analytical solution, the distributions of residual stress in disc-shaped samples of a composite consisting of layers of ceramics having various composition during cooling from the sintering temperature to room temperature are investigated. It is shown that it possible to control the position of the maximum stresses varying the thickness of the layers, and the presence of the diffusion zones in the interface area reduces the magnitude of dangerous stress proportionally to the thickness of these zones. It is noted that for engineering estimates, one should use the values of

Abstract:

Cognitive maps and spatial memory are fundamental paradigms of brain functioning. Here, we present a spiking neural network (SNN) capable of generating an internal representation of the external environment and implementing spatial memory. The SNN initially has a non-specific architecture, which is then shaped by Hebbian-type synaptic plasticity. The network receives stimuli at specific loci, while the memory retrieval operates as a functional SNN response in the form of population bursts. The SNN function is explored through its embodiment in a robot moving in an arena with safe and dangerous

Abstract Di-tert-butyl peroxide or DTBP is a very dangerous organic peroxide, widely used as a modifier, cross-linking agent and polymerization initiator in the industry. Its widespread use pushes us to set up studies assessing the dangers of this product, since it has been at the origin of Bleve explosions producing fireballs with a very devastating power and thermal effects. The hazard studies of this product remain very minimal. Our work consists in determining the thermal effect distances of a resulting fireball during the rupture of a DTBP storage tank, based on the characteristic curves

This paper proposes a rapid vehicle scheduling method to evacuate the crowd and reduce losses in an emergent situation. We construct a specific model for vehicle scheduling problem in disaster rescue firstly, and then put forward a heuristic algorithm to solve this problem. An empirical example is used to evaluate the effectiveness of the method. Scheduling and evacuation data are computed in real-

There is a lot of non-productive time to do sidetrack due to weak clay rocks. The analysis was done to solve these true challenges of the sidetrack into the different production zones. There is a lot of non-productive time for the accident responses because of wellbore lose control. For example, 50 % of drilling time has non-productive time to stabilize wellbore. There are the most effective ways to prevent losing control of wellbore: control
