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 impact zones, during gateway driving and stopping.

In the article is specified, that marine ships considerable part of the operating time work in the straitened districts, in which the width of free passage-way for vessels is limited in the navigation relation by dangers, or intensive navigation. It is marked that in the case of dangerous rapprochement of vessels in the straitened waters at the choice of maneuver of divergence by an operating ship besides a dangerous target it is necessary to take into account preventing ships and navigation dangers in the district of maneuvering, and the existent methods of simultaneous account of dangerous aims and navigation dangers carry analytical character and are bulky and ineffective. The necessity of development of operative and evident methods of warning of collisions of vessels at sailing in the straitened waters is caused to these. The analysis of the last achievements and publications is resulted in work, the decision of the considered problem and selection of parts unsolved before is begun in which. It is shown that binary coordination is the basic method of description of cooperation of pair of the dangerously drawn together vessels, urgent strategies of divergence are considered, the structure of which depends on the conduct of target in the process of divergence, the analysis of procedures of account of navigation dangers is also produced by an analytical method for different types of navigation dangers. Procedure of transformation of the ship safe region set in space of relative motion is offered, in space of veritable motion, a virtual region is formed as a result. It is indicated, that basic properties of virtual regions are: rapprochements of ship with a target dangerous, when the current area of programmatic trajectory of motion of ship gets in the virtual region of target; distance of the shortest rapprochement of ship with a dangerous target will be equal to the set minimum-possible distance of rapprochement, if direction of current area of programmatic trajectory of motion of ship is tangent to the border of virtual region; equality of distance of the shortest rapprochement of ship with a target and set minimum-possible distance of rapprochement is saved at the following of ship on a virtual region tangent to the border to the moment of the shortest rapprochement. It is shown in the publication, that by the computer program dependences of position and form of virtual region on the relation of speeds of ship and target were explored, from distance between a ship and target, and also from bearing on a target. It is shown that depending on distance between a ship and target at the unchanging bearing a virtual region occupies unchanging position in relation to the line of programmatic way of ship, and position and sizes of virtual region depend on bearing on a target.

Extensive effort has been devoted to examining the causal relationship between contributing factors and injury severities. Given the important role of riders’ behaviors in traffic conflicts, this paper aims to analyze the causal effects of traffic conflicts resulting from riders’ behaviors at intersections. The authors collected video data on 152 traffic conflicts caused by riders’ dangerous behaviors in Jiangning District, China. This paper proposes a Bayesian-structural equation modeling (BSEM) approach. Based on the obtained BSEM path coefficient diagram, the factor loadings and path coefficients are analyzed to unveil the potential influence of factors, including personal features, dangerous behavior tendency, temporal and spatial characteristics of dangerous behavior, and the external environment. The results show that compared to human factors, environmental factors have a less direct impact on the severity of traffic conflicts; instead, they have an indirect positive impact on traffic conflicts by affecting behaviors. That is, if riders judge that road conditions are not suitable to conduct dangerous behaviors, they become more cautious in view of current road conditions and time revenue. Furthermore, dangerous cycling behaviors that continue to encroach on the time and space of motorized vehicles are prone to be more dangerous. The dangerous behaviors that continuously encroach on the time and space of motor vehicles (e.g., disobeying traffic signals and riding in a motorway) are significant predictors of serious conflicts. Considering the heterogeneity of riding behavior, these findings could be applied to develop effective education and intervention programs for preventing riders’ high-risk behaviors and improving the traffic environment.

Epidemic data are presented, possible causes analyzed and the dangers of observed in recent years expansion of existing areas of viral infections, including the introduction of the agent to the non-endemic area, evaluated. At the present time there is a significant expansion of the ranges of some zooantroponozes pathogens, particular filovirus Ebola and arboviruses - Rift Valley fever, Zika, Chikungunya. When extending the boundaries of epidemic foci in the new territory for the pathogen, can occur aggravating of clinical manifestations of the disease and increase mortality among the indigenous population. Extremely hazardous exotic viral hemorrhagic fever (Ebola, Marburg, Lassa) when transfer with sick people in some cases, can cause contamination of the contact persons. Rift Valley fever - one of the most aggressive arboviruses, in the case of importation can form stable epidemic foci. Transfer of Zika fever in the territory of the Russian Federation has not represent substantial epidemiological value. Epidemiological factors, essential for the formation of new areas of pathogens may include the presence of permissive candidates in natural hosts and vectors, the climatic conditions. Role of socio-economic factors is significant. Among of environmental factors is the important role of some trace elements, including selenium, involved in the regulation of homeostasis and which faults occur in the upward virulence virus mutating. In parts of Africa and Asia, with soils poor in selenium, were first introduced pathogens or highly virulent strains of influenza A, SARS, Ebola and of SIV, and drifts on these and similar areas have led to an increase in the virulence of viruses.

Extreme sea waves, although rare, can be notably dangerous when associated with energetic sea states and can generate risks for the navigation. In the last few years, they have been the object of extensive research from the scientific community that helped with understanding the main physical aspects; however, the estimate of extreme waves probability in operational forecasts is still debated. In this study, we analyzed a number of sea-states that occurred in a precise area of the Mediterranean sea, near the location of a reported accident, with the objective of relating the probability of extreme events with different sea state conditions. For this purpose, we performed phase-resolving simulations of wave spectra obtained from a WaveWatch III hindcast, using a Higher Order Spectral Method. We produced statistics of the sea-surface elevation field, calculating crest distributions and the probability of extreme events from the analysis of a long time-series of the surface elevation. We found a good matching between the distributions of the numerically simulated field and theory, namely Tayfun second- and third- order ones, in contrast with a significant underestimate given by the Rayleigh distribution. We then related spectral quantities like angular spreading and wave steepness to the probability of occurrence of extreme events finding an enhanced probability for high mean steepness seas and narrow spectra, in accordance with literature results, finding also that the case study of the reported accident was not amongst the most dangerous. Finally, we related the skewness and kurtosis of the surface elevation to the wave steepness to explain the discrepancy between theoretical and numerical distributions.

Rock burst and coal and gas outburst are the most serious dynamic disasters in coal mine and are affected by many factors, such as mining engineering environment. In order to accurately predict the risk area of mine dynamic disasters, a series of impact factors and events are classified, and the spatial data of these factors are managed on the basis of identifying the internal relationship between the impact factors and the disasters. A multifactor pattern recognition model is established by artificial intelligence. The risk probability prediction criteria of mine dynamic disasters and the risk probability values of each unit in the prediction area are determined by using the method of neural network and fuzzy mathematics. The dangerous area, threat area, and safety area of mine dynamic disasters are divided to evaluate the dangerous degree. The corresponding control measures for different dangerous areas are also put forward. Application of the prediction method of mine dynamic disaster factors based on pattern recognition, to improve the implementation of mine dynamic disaster prediction and controlling measures, guarantees the safe production of the coal mine.

A statistical analysis of urgent sea level data in the area of the marine hydrological station Genichesk for the period 1996–2013 was carried out, including the preparation of descriptive data statistics for the studied variation series. During the specified period, 8 most dangerous storm situations were identified. The analysis of storm situations has been carried out, including it has been established at what speeds and directions of the wind dangerous surges occur. It is concluded that dangerous storm surge situations in the study area arise due to the action of winds in the E, NE, ESE, ENE directions with a speed of more than 20 m/s. Dangerous storm driven situations appear when the winds are from NW, WNW directions at a speed of more than 15 m/s. The trend analysis of the variation series showed that there is a long-term trend towards an increase in sea level values in the area of the Genichesk marine hydrological station. This means that in the long term, it may be necessary to revise towards an increase in the critical sea level marks for dangerous rises and falls in sea level.

Abstract In order to analyze the diffusion characteristics of the hydrogen cloud during a liquid hydrogen leakage accident, the Matlab calculation program of liquid hydrogen leakage and diffusion was compiled based on the Gaussian diffusion theory, and analyzed the influence of wind speed, pressure, leakage area and other factors on the size of the dangerous area after liquid hydrogen leakage.The calculation results show that: the wind speed accelerates the diffusion, and the higher the wind speed, the stronger the dilution effect on the hydrogen cloud, and the smaller the dangerous area formed; the increase of pressure and leakage port area will increase the leakage of liquid hydrogen, and as a result, the scope of the dangerous area is increased.

Due to the growing awareness of the extent of degradation of agricultural soils as a result of water erosion, increased attention is paid to the establishing of effective erosion control measures based on reliable and timely input data. When determining the vulnerability of farmland to water erosion, the determining factor is erosively dangerous rains, which are defined as totals over 12.5 mm and intensities of more than 24 mm.h-1. This paper analyses the dangerous erosion rainfalls using data on rainfall intensities of precipitation monitoring network of the company Brněnské vodovody a kanalizace, a.s. (BVK) in the city of Brno. At first, we have set up 14 rain gauge stations distributed over an area of approximately 105 km2 and set basic indicators of individual rainfall episodes. Then we have analysed their maximum 30-minute intensity, kinetic energy and then determined the factor of erosion efficiency. We have found out a significant spatial variability of these variables throughout the area of the city of Brno. The R-factor analysis revealed that the average annual values of R-factor were the highest in the south-eastern part of the city of Brno while the least dangerous erosion rainfalls occurred in the west.

Due to high gas content and a low permeability coefficient in deep coal seam mining, the spontaneous combustion of coal around the wellbore can easily occur, leading to difficulties in extracting gas during the mining process. To determine the dangerous area around the borehole and conduct advanced prevention and control measures are the keys to preventing spontaneous combustion in boreholes. However, the dangerous area around the borehole is not clear, the sealing parameters lack scientific basis, and the key prevention and control measures are not clear, which have caused great harm to coal mines. This study took the 24,130 working face of Pingdingshan No. 10 Mine as an example, using numerical simulation, theoretical analysis, and field tests to classify the risks of studying the surrounding area of the wellbore. The dangerous area variations under different lengths of shotcrete in the roadway were analyzed, the optimal plugging parameters were studied, and the current “two plugs and one injection” plugging device was optimized. Based on the oxygen concentration and air leakage rate, a method was proposed to divide the dangerous area of fissure coal spontaneous combustion around the borehole induced by gas extraction. The dangerous area of spontaneous combustion around the borehole was defined as having an oxygen concentration larger than 7% and an air leakage rate less than 0.004 m/s. The comprehensive control measures of the grouting length at 2–4 m, hole-sealing parameter at 20-13 (hole-sealing depth 20 m, hole-sealing length 13 m) and the “two plugs, one injection and one row” device were determined.

In order to further reveal the failure mode and dynamic response law of dangerous rocks with different degree of weathering in the rock cavity under the action of earthquake and to provide early warning and forecast for steep slope of dangerous rocks in similar earthquake areas, a typical steep slope of dangerous rock in earthquake area of Sichuan, China, was taken as the research object, after detailed geological survey, and according to the chain development law of dangerous rock, the steep slope of dangerous rock before the earthquake was restored. Based on the 3D particle flow software PFC3D, the dangerous rock was divided into 3 modes according to the degree of weathering of the mudstone rock cavity, and the three-dimensional discrete element dangerous rock model under different modes was established. By introducing the horizontal and vertical two-way coupled seismic waves in Wenchuan, Sichuan, in 2008, the failure evolution process of steep slope of dangerous rock under the action of the horizontal and vertical coupled seismic waves was dynamically simulated, which proved the rationality of the simulation. The frequency spectrum of velocity-time history signal of each rock block in the dangerous rock model was analyzed by MATLAB programming, and the time-frequency characteristics of each dangerous rock model under the action of coupled seismic wave were studied. The research results have important scientific guiding significance and practical value for the dynamic stability evaluation and prediction of such steep slope of dangerous rocks under the combined action of rock cavity weathering and earthquake.

For reliable forecasting and prevention of dangerous geodynamic phenomena in the Streltsov ore field area, the geodynamic testing area has been created. The geodynamic testing area includes modern measuring complexes that have different measurement methods and provide effective registration, and in-depth analysis of a wide range of geophysical wave fields changing in space and time. In the presence of anthropogenic seismicity, with the complication of the geomechanical and hydrological conditions of mining, the constant development of methods and means used at the geodynamic test site is required. It is necessary to install additional elements of a multi-level geomechanical monitoring system at sites in which dangerous geodynamic events are predicted and evidence of their reliable precursors. The modernization and integration of the measuring complexes of the geodynamic range into a multi-level geomechanical monitoring system allows to expand the controlled volume of the rock massif, to increase the quantity and quality of the information obtained about the state of the rock massif, which makes it possible to identify regional and local harbingers of dangerous dynamic phenomena and to justify a set of effective measures to reduce the level geodynamic risk improve the quality of forecast evaluation of geomechanical condition.

Destructive natural phenomena are a serious, sometimes unsolvable, regional and local environmental and socioeconomic problem. This paper presents the results of a comprehensive analysis of materials from long-term geomorphological studies in the mountainous areas on the example of the Major Caucasus of Azerbaijan. The dangerous geomorphological processes on the example of the Major Caucasus of Azerbaijan were investigated in detail using large-scale maps, satellite imagery and aerial photography. Geomorphological maps were drawn (map of mudflow hazard and map of landslide hazard in the Azerbaijani part of the Major Caucasus). The research determined the dangerous zones where landslides could cover 65–70% of the total area and outlined the zones and regularities of spread of various types of mudflow origination sites. The analysis of the manifestations of most active (with catastrophic consequences) destructive natural processes and the morphotectonic structure of the studied area showed that the their occurrence and maximum intensity was confined to the weakest plexuses of mountains – intersections of faults and fractures of various directions and orders. A technique for assessing the eco-geomorphological risk to prevent dangerous natural phenomena was offered. The technique is based on the detection of zones with intensive geomorphological processes, which are often not dangerous separately, but could have catastrophic consequences together. The results obtained during the assessment of the effect of natural and man-caused factors on the stability of montane ecosystems may be used to forecast dangerous natural phenomena and to research geodynamical dangerous geomorphological process not only in Azerbaijan, but also in other regions of the Alpine-Himalayan orogenic belt. The obtained results can be used to plan and perform economic activities, determine and minimize the hazards and risks of occurrence of dangerous natural phenomena, and forecast such phenomena in the future.

Abstract The article provides information on transportation of dangerous freight. Legal acts regulating transportation of Dangerous freight are discussed. Major problems and non-compliances with The European Agreement concerning International Carriage of Dangerous Goods by Road (ADR) are distinguished. The type of risk that one encounters is analysed, as well as who is to take responsibility for transportation of dangerous freight. Transport accidents of dangerous substances are increasingly frequent and can cause serious injuries in inhabited areas or pollution of the environment. For quantitative risk assessment and mitigation planning, consequence calculations are necessary. The aim of this article is to present methods of the first approach for calculating costs and overall expenses of an accident and to demonstrate the main recommendations for the next development stage in the area of transport accident modelling. By the means of risk assessment models, it is possible to calculate the extent of the consequences and reduce the risks during the process of transportation. Based on Technology of Dangerous Freight Transportation, the accident calculation principles are suggested, which enables to assess the costs and to find a generalized accident rate. The calculation results are provided.

Abstract. Failures of glacial lake dams can cause outburst floods and represents a serious hazard. The potential danger of outburst floods depends on various factors like the lake's area and volume, glacier change, morphometry of the glacier and its surrounding moraines and valley, and glacier velocity. Remote sensing offers an efficient tool for displacement calculations and risk assessment of the identification of potentially dangerous glacial lakes (PDGLs) and is especially helpful for remote mountainous areas. Not all important parameters can, however, be obtained using spaceborne imagery. Additional interpretation by an expert is required. ASTER data has a suitable accuracy to calculate surface velocity. Ikonos data offers more detail but requires more effort for rectification. All investigated debris-covered glacier tongues show areas with no or very slow movement rates. From 1962 to 2003 the number and area of glacial lakes increased, dominated by the occurrence and almost linear areal expansion of the moraine-dammed lakes, like the Imja Lake. Although the Imja Lake will probably still grow in the near future, the risk of an outburst flood (GLOF) is considered not higher than for other glacial lakes in the area. Potentially dangerous lakes and areas of lake development are identified. There is a high probability of further lake development at Khumbu Glacier, but a low one at Lhotse Glacier.

Climatology is traditionally connected to different conditions of the atmosphere. However, many occurrences appear from time to time. Those occurrences are defined as extreme. Nowadays it is important to study extreme occurrences for every geographical area. In this paper we have investigated one segment of extreme climatic conditions in Eastern part of Serbia - adverse characteristics of precipitation. Data for Negotin were analyzed, as a representative of the climate in this area. Extreme values of precipitation in one place were taken as dangerous occurrences. We have calculated thresholds above which we consider daily amount of precipitation as dangerous. Thresholds for dangerous lengths of rainy and droughty periods were calculated, too.

The security assessment of large underframe on car body is proposed through the SINTAP/FITNET method and with the help of numerical simulation technology of finite element based on some EMU powered car in service at present. The security and reliability of the underframe structure is predicted. The defect tolerance that the underframe is ‘fitness for service’ is put forward in this paper. The result shows that the crack shape a/c has little impact on the security with the semielliptic surface cracks assumption. In addition, the security assessment on dangerous areas and critical crack sizes are acquired based on the assumption a/c=0.2. The critical crack sizes of the dangerous area 1, area 2 and area 3 are about 5 to 5.5 millimeters, while the unilateral penetrate crack size of the area 4 reaches 40 millimeters. The structures are suit for service as the risk of brittle failure is extremely small.

The present investigation project aims to evaluate the extraction of contaminant material from two settling ponds to be used as alternative fuel in two cement plants. The extraction is carried out through mechanical means, and after that extraction, two options are compared: energy recovery and incineration. Through energy recovery, a potentially contaminated area is decontaminated and its waste is used; its high calorific value makes this option a viable one. The waste extraction is carried out through mechanical means due to the high density and viscosity of the waste. Because of these characteristics, the waste undergoes an on-site security adaptation to stabilize it, reduce declivity risk and make it suitable to be handled and moved. The second treatment is carried out in external installations where the final product is obtained (alternative fuel), which is to be used at industrial kilns. The entire described process shows a difference on the consumed energy of 6060.42 kWh/twaste between the two options under study: waste incineration and energy recovery. In addition, it also reduces CO2 emissions on 2.178 tCO2/twaste.

Localization technologies play an important role in disaster management and emergence response. In areas where the environment does not change much after an accident or in the case of dangerous areas monitoring, indoor fingerprint-based localization can be used. In such scenarios, a positioning system needs to have both a high accuracy and a rapid response. However, these two requirements are usually conflicting since a fingerprint-based indoor localization system with high accuracy usually has complex algorithms and needs to process a large amount of data, and therefore has a slow response. This problem becomes even worse when both the size of monitoring area and the number of reference nodes increase. To address this challenging problem, this paper proposes a two-level positioning algorithm in order to improve both the accuracy and the response time. In the off-line stage, a fingerprint database is divided into several sub databases by using an affinity propagation clustering (APC) algorithm based on Shepard similarity. The online stage has two steps: (1) a coarse positioning algorithm is adopted to find the most similar sub database by matching the cluster center with the fingerprint of the node tested, which will narrow the search space and consequently save time; (2) in the sub database area, a support vector regression (SVR) algorithm with its parameters being optimized by particle swarm optimization (PSO) is used for fine positioning, thus improving the online positioning accuracy. Both experiment results and actual implementations proved that the proposed two-level localization method is more suitable than other methods in term of algorithm complexity, storage requirements and localization accuracy in dangerous area monitoring.

Numerical study of mining-induced stress evolution of coal during the top coal caving process under different coal seam thicknesses is carried out, and the numerical prediction agrees well with the field test data. Main characters on stress distribution and dangerous area are elucidated. For the same coal quality, coal layers under 7 m thick fail earlier than thicker coal layers; correspondingly, the internal fracture networks of thin layers are more easily developed. During the mining of a coal layer less than 7 m thick, stress monitoring of the ?dangerous area? in the middle of the top coal should be emphasized, whereas during the mining of coal layers less than 11 m thick, stress monitoring of the ?dangerous area? at the bottom of the top coal should be highlighted. The research is to optimize caving technique and extraction process.

Analysis of the movement trajectory and risk assessment of the high-slope dangerous rock mass collapse are of great significance for preventing and controlling the geological disasters of collapse. This study firstly takes the dangerous rock mass of the high slope in Pu’erdu Town, Yanjin County, Zhaotong City, Yunnan Province, as the research object, calculates and analyzes the trajectory of collapse movement of several groups of dangerous rock mass with great threat, and RocFall are used to carry out numerical simulation analysis and verification. Secondly, the risk and vulnerability of the dangerous rock mass in the study area are analyzed, and the risk evaluation is carried out through the risk evaluation matrix to clearly define the risk level. Results show that if the dangerous rock mass collapses, the horizontal movement distance was approximately 53–88 m, and the maximum bounce height of the platform was approximately 3–18 m, which will seriously threaten the life and property safety of residents. There is little difference between the simulation of the collapse of dangerous rock mass by RocFall software and the calculation result of the formula. Although RocFall software is more intuitive and can be directly compared with charts, software cannot completely simulate the actual situation, and it is only suggested as a reference from design rather than a basis of design. The result of risk evaluation shows that there are 2 high-risk dangerous rocks, 3 medium-risk dangerous rocks, and 1 low-risk dangerous rock in this area. It is suggested that a reasonable and scientific engineering treatment scheme should be put forward as soon as possible in combination with the collapse trajectory of the collapsing movement.

A study of work accidents in forests has shown that dangerous trees play an important role in forest accidents. Despite the importance of safe working environments for forestry operations, the definition of these areas in natural forests is still unclear. Dangerous trees are considered those snagged with broken branches and a canopy or ones with dead trunks and stumps that have a hazard potential to the forest workers. This study investigates the frequency of these trees in the managed and unmanaged forests in the Caspian forests of Iran. In order to do the study, 15 circular plots with a total area of 1,000 square metres in two studied parcels were selected and the trees, according to their dangerous characteristics, were evaluated. The final results indicated that 66 and 50 trees per hectare had signs of being dangerous trees in the managed and unmanaged stand, respectively. A comparison of the average number of dangerous trees in the two studied parcels using the Mann-Whitney test indicated a significant difference so that the average number of dangerous trees in the managed parcel was more than the ummanaged parcel. Trees with broken branches had the highest frequency in the managed stand, while trees with a dead trunk or stump, a broken branch and canopy in the unmanaged forest were more than the other classes. Considering the relative frequency of the dangerous trees in the two study areas, identifying them could be one of the main attempts in logging safety. The existence of hazardous trees with different risk classes in each of the forest stands requires the development of specific safety instructions to deal with the risks of each tree. <br /><br />

Tsunami is one of the catastrophic events that threatened coastal areas in Morotai Island Regency. This is partly because the location of the regency is among several active faults. Therefore, the study aims to analyze the tsunami inundation area and determine a tsunami evacuation route in Daruba Pantai Village, South Morotai District. This study begins with the preparation of a digital elevation model and is compiled with other related maps to produce the tsunami inundation area at the study site. The study results show that a tsunami can hit 176.65 ha, with the disastrous and dangerous category being 5.02% and 0.66%. Meanwhile, specifically for the Daruba Pantai Village area with an area of 60.59 ha, the disastrous and dangerous categories are 10.72% and 1.30%, and the safe category is 36.61% and secure 23.07%. Furthermore, the preparation of the evacuation route is based on the scenario that residents from each zone of both the Neighborhood Unit (RT) and Community Unit (RW) are directed to follow the evacuation path to move towards the temporary shelter point and towards the safety zone.

AbstractIn the 1950s and 1960s serious nuclear accidents and ongoing pollution by waste disposal from the ‘Mayak’ plant affected the Techa River region in the Southern Urals (Russia). These episodes were clouded in secrecy during the Soviet period, such that even local people were unaware of the dangers. Virtually all families have been affected by radiation sickness. Yet even today people still live in the affected area. The article describes how three generations of the population has adapted to life in such dangerous conditions and it outlines the very different responses of men and women and of the various ethnic groups living in the area (Tatars, Bashkirs, and Russians).

The present study aims to extract the polluting material from a lagoon and use it as an alternative fuel in cement industries. To this end, in the methodology will analyze two alternatives for the waste: fuel generation and incineration. The polluting material from the Arganda lagoon has highly calorific value to be used as fuel. Thus, not only are these wastes used, but also an area with potentially hazardous waste is decontaminated. After the extraction, which due to the characteristics of the material is chosen for the novel pumping extraction, and subsequent generation of fuel, the process for using this waste is through the distribution of the created fuel to nine cement plants in Spain, leading to significant environmental benefits. The results of the process shows an energy efficiency of 97% for using the waste as fuel, and a consumed energy of approximately 6000 kWh/t·waste to the process that leads to the desired environmental benefit. The use of waste contributes to the reduction of CO2 emissions and a decrease in the use of fossil fuels.

The paper contains a summary of results obtained when researching demand for transporting dangerous goods of class 3 (oil and oil derivates) in the area of the city of Belgrade in 2007. Considering all transport modes used for carrying oil and oil derivates (road, rail and water transport), we present the total quantities of transported goods on a percentage basis. In light of road transport, the paper presents the features of demand for transport in terms of time and space that are a basis for the management of transporting dangerous goods and input to defining transportation routes to dangerous goods. Among the features of demand for transport in terms of time, the paper presents the quantities of goods transported within different months of the year, different week days and different periods of the day. The features of demand for transport in terms of space presented in the paper are goods flow features depending on their origin and the destination of movement in relation to the defined serviced area and the load of traffic network with goods flows.

Mining of split rock or ultramafic igneous rock, located in the Awangbangkal area, Karangintan District, Banjar Regency, South Kalimantan Province, causes steep slopes. The formation of the Meratus Mountains is an oceanic bedrock that is exposed to the earth's surface and is mined by local residents using simple tools or semi-mechanical equipment carried out by the company. Positive impacts arise but negative impacts will also build up over time. Day by day more dangerous slopes were formed. The local government became worried because it was dangerous. This writing is compiled based on the results of direct measurements in the field using the Theodolith unit. The measurement results are processed using Autocad Landesktop 2009 software. The analysis is by classifying the slope of the formed slopes according to the data that is already in digitized form. The result is a dangerous area on the east side, because it has a slope of 25% -45% (steep). Although from a geological point of view this area is stable because it is formed by igneous rocks, from the local government side this is a concern for the people who do work in the area.

The unwanted flow of matter is governed by chemical equations like Fick’s Law (diffusion of mass), the Arrhenius Law (rate of reaction), and most importantly the Nernst Equation (yielding the electrochemical potential of species). In addition to these chemical equations, the other unifying sutra (or “suture”) of eclectic dangerous goods problems, and the one that will be employed in this paper, is the construction of Gaussian surfaces through which energy may flow. This energy could be electromagnetic radiation, heat, ionizing radiation, non-ionizing radiation (light), acoustic energy, or even just fields. Once an equation is developed for the flow through a unit area of a Gaussian surface, a comparison can be made between an exposure and some Exposure Limit. And, there are many different types of limits depending on the conditions of the exposure. But, in general, if an exposure is below the Exposure Limit, then safety is implied. Above the limit, steps must be taken to provide shielding. In this paper, attention will be focused on the hazards produced by flows of ionizing radiation energy emitted from a source. Ionizing radiation can penetrate deeply into matter and is capable of removing electrons from neutral atoms all along its path. Such widespread damage can disrupt DNA and, ultimately, result in carcinogenic tumors.

Abstract Illegal fishing net use is one of the most serious threats to the health of the world’s fisheries and for the secure employment of fishers. Illegal modes of fishing adversely affect the fishing industry according to the Fisheries and Aquatic Resource Ministry of Sri Lanka which is the regulatory body of the fisheries industry. In Sri Lanka, usage of illegal fishing methods has increased in recent years. There is an urgent need to identify prohibited or illegal fishing activities and the use of dangerous or harmful substances in fishing. The present study was carried out in the Mannar coastal area from June 2013 until the latter part of June 2014, to identify illegal, prohibited and dangerous fishing activities, and to understand the major threats and impacts on the fishing community and the socio, economic, biological and ecological impacts through field surveys and library methods. The study aims to outline appropriate planning and solutions to minimize illegal fishing and to save the coastal biodiversity and fishing community.
