The article summarizes existing information about the current surface manifestations of the covered carbonate karst in Moscow city territory. The analysis of engineering-geological conditions of sinkholes area in the north-west of the city is performed. The confinement of the sinkholes to places of overlapping of different ages entrenched streams and sites of ancient karst disturbances is noted. The technogenic reasons for the activation of sinks in the middle of the 20th century are considered and it is shown that the main factor is the change in the hydrodynamic regime. The most significant emergency situations in the north-west of Moscow were investigated and measures for liquidating the consequences, whose cost along with the value of destroyed objects determines the magnitude of direct economic damage, are characterized. On the example of a concrete sinkhole, the dynamics of emergency situation development are traced. The estimation of design decisions used for preservation of buildings and constructions stability in the places of possible sinkholes formation is given. It is concluded that one of the most important tasks of studying the development territories of a covered carbonate karst is to identify areas where ancient and buried old sinkholes are present and to classify these areas as hazardous. Now in Moscow there is only one such district in the north-west with an area of about 11 km2, despite the fact that sinks arise regularly throughout the city area. A rather complete information has been collected on the collapses and subsidence for the period from the beginning of the 20th century to the present day and an attempt has been made to reveal the superficial manifestations of karst in other parts of the city similar in geological conditions to the north-western region. A retrospective analysis of the engineering-geological conditions of the sites of modern sinks development is made and the karst-suffusion genesis of several collapses in the central part of Moscow has been determined, which gives grounds to single out another hazardous region here.

Flooding is a dangerous phenomenon, causing emergency situations and causing material damage, capable of damaging health, and even death of people. To reduce the risk and economic damage from flooding, it is necessary to forecast flooding areas. An effective method of forecasting emergency situations due to flooding is the method of remote sensing of the Earth with integration into geoinformation systems. With the help of satellite imagery, a model of flooding was determined based on the example of Tavda, the Sverdlovsk Region. Space images are loaded into the geoinformation system and on their basis a series of thematic layers is created, which contains information about the zones of possible flooding at given water level marks. The determination of the area of flooding is based on the calculation of the availability of maximum water levels at hydrological stations. According to the calculated security data, for each hydrological post, flood zones are constructed by interpolation between pre-calculated flood zones of standard security. The results of the work can be used by the Main Directorate of the Ministry for Emergency Situations of Russia for the Sverdlovsk Region.

Abstract. The so-called El Trébol is a critical road interchange in Quito connecting the north and south regions of the city. In addition, it connects Quito with the highly populated Los Chillos Valley, one of the most traveled zones in the Ecuadorian capital. El Trébol was constructed in the late 1960s in order to resolve the traffic jams of the capital city and for that purpose the Machángara River was rerouted through an underground concrete box tunnel. In March 2008, the tunnel contained a high amount of discarded furniture that had been impacting the top portion of the tunnel, compromising the structural integrity. On 31 March 2008 after a heavy rainfall a sinkhole of great proportions formed in the Trébol traffic hub. In the first few minutes, the sinkhole reached an initial diameter of 30 m. The collapse continued to grow in the following days until the final dimensions of 120 m in diameter and some 40 m of depth, revealing the Machángara River at the base of the sinkhole.A state of emergency was declared. The cause of the sinkhole was a result of the lack of monitoring of the older subterranean infrastructure where trash had accumulated and damaged the concrete tunnel that channelized the Machángara River until it was worn away for a length of some 20 m, leaving behind the sinkhole and the fear of recurrence in populated areas.With the intent to understand the causes and consequences of this sinkhole event, rainfall data are shown together with hydrogeological characteristics and a view back to the recent history of sinkhole lineation or arrangement of the city of Quito. The economic impact is also emphasized, where the direct costs of the damage and the reconstruction are presented and compared to indirect costs associated with this socio-natural disaster. These analyses suggest that the costs of indirect financial damage, like time loss or delay, and subsequent higher expenses for different types of vehicles, are equivalent to many times the costs of the reconstruction of El Trébol.

Little is necessary in terms of an introduction, since Amarna is one of the best-known settlements of ancient Egypt. The city was founded by pharaoh Amenhotep IV, known from his fifth regal year as Akhenaten, on his move away from Thebes and Memphis to found a new religious and administrative capital city. Akhenaten reigned approximately between 1348 and 1331 BC, and his principal wife was Nefertiti. Akhenaten’s direct successor appears to have been a figure named Smenkhare (or Ankhkheperure) who was married to Akhenaten’s daughter Meritaten. Like Nefertiti, Smenkhare/Ankhkheperure held the throne name Nefernefruaten. For this reason it is uncertain whether this individual was Nefertiti, who may have reigned for some years after the death of Akhenaten, possibly even with a brief co-regency, or whether this was a son or younger brother of the latter. The rule of Smenkhare/Ankhkheperure was short, and he or she was eventually succeeded by Tutankhamun. The core city of Amarna was erected on a relatively flat desert plain surrounded by cliffs on the east bank of the Nile, in Middle Egypt, approximately 60km south of the modern city of Minia, surrounded by the villages et- Till to the north and el-Hagg Qandil to the south. The site was defined by at least sixteen boundary stelae, three of which actually stand on the western bank, past the edge of the modern cultivation. In total, the city measures 12.5km north–south on the east bank between stelae X and J, and c.8.2km west–east between the projected line between stelae X and J and stela S to the far east, which also indicates approximately the longitude of the royal tomb. The distance between stelae J and F, to the far south-west, measures c.20km, and between stelae X and A, to the far north-west 19.2km. The core city, which is the part of the settlement examined in this section, was erected along the Nile, on the east bank, and it is defined by the ‘Royal Road’, a major thoroughfare running through the entire core city north–south.

The safety of technological processes and order of elimination of the emergency situations arising on fire and explosion hazardous objects with availability of flammable liquids and vapours, the reasons and the mechanism of appearance of an emergency situation is considered. The analysis of process of emergence of an emergency situation on potentially hazardous production facility in Russia and St. Petersburg is made. Mechanisms of development of an emergency on the object containing fire and explosion hazardous and easily flammable liquids at various scenarios of passing of an emergency situation are constructed: floods, ignitions and manifestations of secondary dangerous factors. Priority tasks for carrying out effective and safe mitigation of consequences of the arisen emergency situation are designated. The technology and models elimination of an emergency situation on the object containing fire and explosion hazardous and easily flammable liquids on the example of explosion with the subsequent burning of the gas mixture formed in a consequence of evaporation of oil products in reservoir park of Ruchi oil depot in the city of St. Petersburg is developed. Recommendations for the officials controlling actions for elimination of an emergency situation on this object are developed.

In this paper, the impacts of some meteorological parameters on the SO2 concentrations in the City of Obrenovac are presented. The City of Obrenovac is located in the north-west part of Serbia on the banks of the River Sava. The observed source emission, the power plants TENT A and TENT B are situated on the bank of the Sava River in the vicinity of Obrenovac. During the period from January to November 2006, the concentrations of sulfur dioxide in the air at 4 monitoring sites in Obrenovac were measured. It was noticed that the maximal measured daily concentrations of sulfur dioxide ranged from 1 ?g/m3 (16th November, 2006) to 98 ?g/m3 (29th January 2006) and lie under the maximal allowed concentration value according to the Serbian Law on Environmental Protection. The measured sulfur dioxide concentrations mostly showed characteristics usual for a daily acidification sulfur dioxide cycle, excluding the specificities influenced by the measuring site itself. Sulfur dioxide transport was recorded at increased wind speeds, primarily from the southeast direction. Based on the impact of meteorological parameters on the sulfur dioxide concentration, a validation of the monitoring sites was also performed from the aspect of their representivity.

AbstractCities develop around industry, markets and transport links. Dublin in the nineteenth century was similar, but additionally the north-west of the city developed around the expansion of a complex of institutional buildings for the reception, confinement and welfare of the poor and sick. This article argues that these institutions were implicit in the development of the modern city in the same way as industry and commerce. The physical development of the buildings altered and defined both the streetscape and, over time, the social identities and historical communities in the locale, in the same way that industrial development defined urban areas.

Abstract Mastitis in cows in the farms of the Russian Federation cause great economic damage. Economic losses include the cost of treating cows and the cost of recycled milk. In the farms of the North-West region of the Russian Federation mastitis occurs in 20–30% of lactating cows. An important task is to find effective ways to prevent mastitis. The task of our research included the study of the effectiveness of external use of staphylococcal toxoid. For the experiment, 2 experimental groups of dry cows of 10 animals each were formed. For the first group of cows, 5 days before the expected date of calving, an ointment containing staphylococcal toxoid and dimethyl sulfoxide was applied to the area of the milk mirror. Udder treatment was performed once a day for five days. Cows of the second group were immunized with Starvac® vaccine in accordance with the instructions, twice during the dry period. The third group of cows (n = 20) was the control. After calving, the concentration of immunoglobulins in colostrum was examined in all cows. In cows of the first group, the concentration of immunoglobulins G, M and A in colostrum was 8.59 ± 0.9; 1.1 ± 0.13 and 5.42 ± 0.9 g / l, respectively. The concentration of immunoglobulins in cows of the first group was higher, on average, by 1.3–2.0 times in comparison with cows that were given the Starvac vaccine. In comparison with the control group, the growth of all classes of immunoglobulins was determined by 2.2 - 5.2 times (P < 0.01). The results obtained showed high efficacy of external use of staphylococcal toxoid together with dimethisulfoxide.

Introduction. At present, the understanding that the solution of economic problems facing Russia cannot be based on standard economic approaches and models. It is gradually becoming obvious that attention to the spatial and historical features of the development of the Russian economy has not only academic interest, but also quite obvious practical significance. This can be proved on historical, or more precisely, historical and economic material. In fact, the theory of logic, taken broadly, is based on this. The development of transport and versatile tool to reduce the adverse impacts of space on the eco-economy, physical space turns into economic. The lack of transport connectivity of territories devalues the space of the economy (economic space) to a physical or geographical space. The purpose of the article is to show the role of the city of Saint Petersburg in the economic space of the North-West (understood as Saint Petersburg, Saint Petersburg, Novgorod, Pskov provinces) and Russia as a whole, through the development of railway transport in a concrete historical way. Materials and Methods. The historical method is used as the main method. In Russia, the spatial analysis method is almost mandatory, and it is also applied in this article. This method has been widely used in economic history, particularly in the study of transport. At the same time, we recognize the existence of research methods and techniques that are not suitable for this work, for example, the practice of economic and demographic analysis, especially in the neo-Malthusian version. The authors involve in the analysis the works of Russian and foreign scientists on the topic of the article. Results. The article shows the role of the city of Saint Petersburg as an economic and transport center taken in historical dynamics. The role of an important but single transport center in the economic development of Russia is revealed. The thesis is proved that the optimal choice of reference points for economic development has a positive impact on the development of the economic space of the entire country. Discussion and Conclusion. The article proves that the spatial scale of Russia contributes to the fact that the financial results of economic activity can be localized at a significant distance from the place of economic activity.
