Authors: Kvashuk Sergey , Smyshlyaev Boris , Trunev Vasiliy
Published: January 2019

Kuznetsovskiy tunnel is built in the pass section of Sikhote-Alin Ridge on the Pivan-Sovetskaya Gavan leg of the Far Eastern Railway route, Russia. The tunnel axis is crossed by a system of faults of various capacities. The fault zones are associated with increased fracturing, reduced stability, abundant water inflows in some places, the threat of dumping, intense silicification and sulfide mineralization. The monitoring data obtained by natural pulsed electromagnetic field of the Earth (NPEFE) and dipole electromagnetic proliferation (DEMP) methods made it possible to come to a conclusion about the real picture of the development and to make forecast of the rock pressure, as well as the dynamics of groundwater entering to the workings for the further tunnel's safe construction and operation.

Authors: Awwad Talal , Ulitsky Vladimir , Shashkin Alexey
Published: January 2019

The entire civilized world follows the state of unique monuments of the east, including Syria, where military operations are not yet over. Separate monuments of antiquity have been destroyed, which require immediate examination and, at a minimum, preventing structural elements from collapse. Naturally, publications of the time of the Second World War (Russia, Japan, Poland…) most fully represented the world restoration practice of destruction from mass bombardments and shelling. For these works, it is possible to systematize the degree of danger of the state of the objects at the time of their possible restoration and to estimate the damage caused by the enlarged parameters. Unfortunately, today, the revision of this practice, taking into account modern technologies of engineering restoration of damaged and reconstructing lost monuments, becomes urgent. Without this, it is impossible to defeat the vandals of the 21st century.

Published: January 2019

During construction of the monolithic reinforced-concrete foundation, it is not easy to monitor both a continuous haulage and technology of concrete placement. For that matter, some breach of the foundation structural integrity may occur. Currently, there is no unanimous integrated practice of monitoring concrete placement for building oversize solid reinforced-concrete foundations. The surveying results of the solid concrete foundation dimensioned 16m by 16m and from 2 to 3.5m thick are set forth in the article. Such geophysical technique as seismoacoustic sounding has proved effective for concrete placement quality control of monolithic reinforced-concrete foundations by means of a non-destructive method.

Numerical studies of steel pipe sheet pile
Authors: Alpatov Vadim , Bezuglov Alexandre
Published: January 2019

The sheet pile wall (SPW) is carried out from pipes of big diameter which plunge into soil very deeply. Depth of pipes is the settlement size depending on a set of parameters. Depth of pipes provides rigidity and reliability of a construction. SPW has a high rate of a consumption of steel on his production. Authors of the present article suggest to reduce a material capacity of SPW at the expense of reduction of depth of blockage of every second pipe. Decrease in depth of blockage of separate pipes is carried out at preservation of the maximum depth of blockage of other pipes. The design similar to a «comb» because of alternation of long and short pipes turns out. Such decision allows to reduce the total depth of blockage of pipes and as a result leads to decrease in a material capacity and cost of a construction in general. The problem of search of possible reduction of length of a part of pipes is the purpose of the real research. As solutions of the put problem we suggest to execute numerical experimenting in iterative statement with use of modern software. Results of numerical researches of SPW are presented in the present article. The presented results allow to draw a conclusion on efficiency of the solution on decrease in a material capacity of SPW proposed by authors. For obtaining the generalized decision and obtaining undoubtedly the best result of a design of SPW authors consider necessary to execute problem definition in the form of parametrical optimization.

Published: January 2019

When designing a parking lot of limited size with a large elevation difference, a decision to construct an earth embankment with a retaining wall was made. Based on the analysis of the results of engineering geological surveys and construction conditions, four options of constructing a retaining wall were considered. The stress-strain states of the protective structures and embankments were studied in details with the help of finite element modeling in order to select the optimal technical solutions for retaining walls. Based on the analysis of the distribution of stresses and strains in the structures, the advantages and disadvantages of each option are determined. The optimal combined version of constructing a thin retaining wall with unloading screens and hardening of the embankment by means of anchor-injectors is substantiated.

Authors: Svatovskaya Larisa , Sychov Maxim , Drobychev Ivan
Published: January 2019

The paper deals with modern geosystem problems and suggests ways of solving them. The main aim of the study is to develop new methods of geosystem preservation on the base of geoecochemistry through geoecochemical reactions. Both theoretical, namely thermodynamic, method and experimental one are used in the research. Three new geoecochemical techniques such as energy economy, soil restoration and alternative technologies are introduced for natural resource preservation. Every technique is estimated with relation to negative changes of Gibb’s free energy. These changes take place as a result of geoecochemical reactions and determine a level of geosystem preservation. Using the first technique it is possible to save energy, a few hundreds of kilojoules per mol, due to formation silicates, phosphates, etc. Other techniques of geosystem restoration are heavy metal ion detoxication and alternative technologies, e.g. lithosynthesis, for natural resource preservation. Geoecochemical techniques of lithosphere preservation can be useful for any geoconstruction technology like soil strengthening, highway and railway construction and other earthwork operations.

Authors: Sakharova Antonina , Kozlov Ivan , Baydarashvili Marina , Petriaev Andrei
Published: January 2019

Consumption and pollution of natural resources must be constantly compensated by their conservation, saving and restoration to create a balance in the ecosystem between man and nature. To solve this problem any construction process must be accompanied by geoecoprotective measures. The authors of the article suggest to use silica sol in the soils stabilization and reinforcement technology. Silica sol is a pure mineral product that has binding properties and neutralizing properties against some pollutants. This makes it suitable for soils reinforcement and also soils neutralization from pollutants such as heavy metals ions. The stabilization technology using technogenic soils and silica sol will conserve natural resources, improves the soil strength properties and neutralize them from pollutants.

Authors: Royant-Parola S. , Legris S.
Published: January 2019

During adolescence, sleep changes physiologically and biologically. It is during this period of life that development and learning takes place. However, new teenager sleep behaviors appear. A decrease in weekly sleep time and a jet lag during weekends contribute to the deterioration of teenager’s sleep. The use of new social media plays a detrimental role, with a strong negative correlation between time spent on those and sleep time. Teenagers suffering from sleep deprivation develop well-identified consequences such as diurnal fatigue, lack of attention, more anxiety, poor self-esteem, and also an increased risk of obesity and depression. Teenage sleep is a real public health issue.

Randomness vs. fuzziness in managerial decision-making
Authors: Hašková Simona
Published: January 2019

Managers often deal with uncertainty of a different nature in their decision processes. They can encounter uncertainty in terms of randomness or fuzziness (i.e., mist, obscurity, inaccuracy or vagueness). In the first case (randomness), it can be described, for example, by probability distribution, in the second case (fuzziness) it cannot be characterized in such a way. The methodological part of the paper presents basic tools for dealing with the uncertainty of both of these types, which are techniques of probability theory and fuzzy approach technique. The original contribution of the theoretical part is the interpretation of these different techniques based on the existence of fundamental analogies between them. These techniques are then applied to the problem of the project valuation with its “internal” value. In the first case, the solution is the point value of the statistical E[PV], in the second case the triangular fuzzy number of the subjective E[PV]. The comparison of the results of both techniques shows that the fuzzy approach extends the standard outcome of a series useful information. This informative “superstructure” of the fuzzy approach compared to the standard solution is another original benefit of the paper.
The fuzzy approach for estimating the creditworthiness and credit risk of issuers of corporate bonds
Authors: Hašková Simona
Published: January 2019

The uncertainty in the financial market is often perceived as a risk of deviation from expected results. However, uncertainty is associated with vagueness in the sense of ambiguity or obscurity, which, unlike the risk, is not describable in the form of deterministic or stochastic models. Given the vagueness of the data entering the credit risk assessment models, the fuzzy decision-making process is introduced in the theoretical part and implemented in the application part as an effective alternative to standard models. The fuzzy approach is used to address the problem of the creditworthiness of the corporate bonds issuers and the credit risk. Data sources are of a qualitative and quantitative nature based on the ratings of Standard and Poor's and Moody's and financial indicators relevant for the creditor. The resulting creditworthiness and credit risk values rectify the credit ratings of rating agencies and are the original contribution to the topic solved. In conclusion, the impact of company ownership on the creditor´s subjective perception of creditworthiness, or respectively credit risk is outlined.

Authors: Maslak Olga , Sokurenko Petro , Grishko Natalya , Maslak Mariya
Published: January 2019

The work covers the theoretical and methodological foundations of marketing for an export-oriented enterprise. At the present stage of development of the economy, the use of marketing tools in activities is a powerful means of increasing the enterprises` competitiveness, strengthening adaptive characteristics when external conditions and market conditions change. Consumption volumes are the driving force of the production activity of the enterprise, affecting the nomenclature, range and scale of production. The introduction of the marketing concept, which focuses on the production of products that are in the market demand, stimulates the production of products needed by the consumer. Theoretical and methodological issues of marketing aimed at restricting the demand for irrational demand products (opposing marketing) attract the attention of scientists and practitioners. At the same time, the choice of the topic was due to insufficient research of this scientific problem as a whole and its relevance for the economy of Ukraine, especially in the context of the development of cooperation with the European Union. A detailed study of the tools of opposing marketing allows export-oriented enterprises to ensure the profitability of commercial and marketing activities, while the harmful effects of the consumption of goods of irrational demand determine the feasibility of research and analysis of the conditions and their consumption motivation. The demand for these products is undesirable; therefore, countermeasure marketing at the state level is controlled by the relevant organizations.

In this study, attention is paid to the analytical and regulatory aspects of determining the current state and trends of marketing support for the tobacco industry enterprises activities. The features of a complex of marketing support formation of their activities in the conditions of risk and uncertainty are determined.

This paper calculates the influence and induction coefficient based on the input-output theory, in order to evaluate the current situation of Beijing’s service industry and its effects on regional development. With online comparison, the author concludes that the service sector is getting more and more important on economic development, while the second industry is still the pillar of growth. The author also finds that the impact of service sector’s influence coefficient on the growth rate of regional economy and the scope of industry is weaker than the induction coefficient. At last, this paper shows that the fundamental compelling power for Beijing’s service development is from the demand side of market, and this gives the benchmark point for policy making in service sector.

The market of Russian bonds denominated in foreign currencies was considered as the primary target for the initial package of the USA and EU economic sanctions in 2014. The analyses showed that, by the end of 2017, there was a significant reduction in the number of outstanding bond issues denominated in foreign currencies and a sharp increase in the bonds nominal volume evaluated in Russian rubles. The sanctions did not lead to a significant change in the structure of the market either from the standpoint of the number of bond issues denominated in foreign currencies or in terms of their nominal value. However, the number of foreign currencies in which bond issues were denominated was reduced from 11 to 6.

Background and study aims Cold snare polypectomy (CSP) is considered to be effective in reducing risk of delayed bleeding but randomized trials fail to support this owing to the small sample size. The current study aimed to compare risk of delayed bleeding before and after implementation of CSP in a screening colonoscopy setting.

Patients and methods This study retrospectively analyzed a prospectively maintained screening colonoscopy database in a university hospital in Taiwan. We compared the rate of delayed bleeding before and after implementation within similar periods (18 months and 15 months) and the respective number of polypectomies (1,304 and 1,255) performed to remove small and diminutive polyps. The main outcome measurement was delayed bleeding within the two periods. Multivariate analysis was performed to adjust for major confounders.

Results A total of 1,304 and 1,225 subjects received hot snare polypectomy (HSP) and CSP in two separate periods, respectively. Compared with the HSP, the CSP had a lower rate of delayed bleeding (0.1 % vs. 1.1 %, P < 0.001), severe bleeding (0 % vs. 0.7 %, P < 0.01), need for second-look colonoscopy (0 % vs. 0.8 %, P < 0.01), and emergency service visits (0.1 % vs. 1.0 %, P < 0.01). Total procedure time (12.60 ± 11.45 vs. 16.48 ± 14.27 min/person, P < 0.01) and duration of hospital stay (1.18 ± 0.50 vs. 1.53 ± 5.78 hour/person, P < 0.03) were also shorter after CSP implementation. Multivariate analysis showed that HSP was an independent risk factor for delayed bleeding after adjusting for age, gender, and number of polyps (adjusted odds ratio 14.4;95 % confidence interval = 1.88 – 110.6).

Conclusion Implementation of CSP significantly reduces risk of delayed bleeding associated with removing small and diminutive polyps in screening colonoscopy.

Hereditary hemorrhagic telangiectasia (HHT) is an underreported autosomal dominant vascular dysplasia. Neonatal presentations of HHT are rare, as this disorder typically presents in adolescence or beyond with epistaxis. We report a female neonate with hematochezia on the 1st day of life secondary to multiple gastrointestinal arteriovenous malformations (AVMs) along with intracranial hemorrhage. We describe her clinical course and management, as well as her novel family mutation in ENG. This is the first reported HHT case with significant gastrointestinal bleeding in the newborn. We review neonatal HHT and raise the consideration for more directed prenatal imaging and delivery options for fetuses at high risk of HHT.

The aim of this study was to investigate the relationship of two single nucleotide polymorphisms (SNPs) in the interleukin-18 (IL18) gene (rs187238, g.-137G > C; rs1946518, g.-607C > A) and one SNP of the IL12B gene (rs3212227 g.*159A > C, 3′UTR) with the age of onset for type 1 diabetes mellitus (DM1). A total of 1,101 patients with DM1 enrolled in 13 centers from different regions of Brazil were genotyped with TaqMan assay and classified according to the ancestry. Our results show that an SNP in IL18 gene could be associated with DM1 age onset, taking into account that this studied variation affects gene expression.

Extracranial carotid artery aneurysm is a rare vascular disease in the neck with variable presentation. Aneurysms are associated with significant mortality and morbidity and are associated with fatal complication secondary to spontaneous rupture or tracheal compression or laryngeal edema and distal embolization. A 43-year-old male patient presented with large aneurysm arising from proximal common carotid artery (CCA) causing tracheal obstruction leading to life-threatening respiratory symptoms. The endovascular interventional management is an emerging alternative for surgical option and providing promising results with almost similar safety and efficacy. Endovascular management of an extracranial carotid artery aneurysm using stent graft is minimally invasive and effective.
