Authors: Shcherbakov Vladimir , Akulshin Alexander , Chizhik Konstantin , Tolstoy Mikhail
Published: December 2018

Constructions for water withdrawal are the constitutive building industry component. The cost of these constructions is rather high. That is why while designing it is necessary to choose optimal design model and operating conditions during design life. Operation experience showed that the wells are desirably placed along one line to provide the most optimal conditions for water withdrawal. While designing the wells interaction is considered as a group operation if the distance between them is less than two radiuses of influence. Such wells disposition allows reducing the area and cutting down the investments for water withdrawal construction and also creating the better conditions for equipment and mains operation. Design of interacting wells consists of finding the tube well number, the distance between them, the discharge and levels (static and dynamic). At operating condition determination, it is necessary to consider the combined action of pure water reservoirs and tube well.

Authors: Primin Oleg , Varyushina Galina , Ten Andrey
Published: December 2018

Surface run-off from developed urban territories, be it orderly disposed surface run-off or diffused surface run-off, is among the main sources of man-made pollution and degradation of urban water bodies lo-cated within the boundaries of Moscow. In the present-day context, the improvement of their ecological condition is possible only in case of im-plementation of measures aimed at the reduction of human-induced impact on water bodies, elimination of accumulated environmental damage, re-covery of their self-purification ability and groundwater protection against pollution. The authors give the results of the seasonal monitoring of sur-face run-off composition and the composition of sludge produced by the treatment facilities located on urban territories of different functional pur-pose. The studies proved the idea that the application of polymeric floccu-lants intensifies the process of dewatering the sludge produced by treat-ment facilities in different seasons. The criteria characterizing the main ef-ficiency indices for the selection of technological approaches and equip-ment, were developed based on generalized and summarized experience in seasonal observations and evaluation of process and hydraulic parameters of the operation of surface run-off treatment facilities.

Published: December 2018

The availability of highly economical indicators of convective type heating appliances, as well as the wide use of window sills, solid glazing of walls in the construction equipment, and the expansion of the use of convective (ribbed) type heating appliances, taking into account the possible improvement of their sanitary and hygienic and heat engineering properties. Constructions of convective type (convector) type heating devices with rather low heat engineering indicators. To improve the thermo-technical qualities of convectors, special attention is paid to the determination of the optimum dimensions of the fin, the channel for the passage of the coolant, the fin length, the optimum shape of the rib, and so on. The task of this work is to find new ways that require the heat transfer process of ribbed heating devices. The problem of the optimal distribution of the heat source (channel for the passage of the coolant) relative to the horizontal axis of symmetry of the rib is considered. Analytical dependences are obtained, which allow to determine the local values of heat transfer changes for nonisothermal plates, the temperature change at which is a step-change function. The process of convection in a laminar boundary layer is shown as a process of nonstationary thermal conductivity of a semi-boundary body. When solving the problem of radiant heat exchange between the ribs and surrounding surfaces, and between the edge and the environment. The directions of the experimental study are presented with the purpose of determining: the thickness of the boundary layer near the surface of the rib; the nature of the distribution of temperature along the edge with different locations of the source of heat; thermal engineering studies on convectors, various measurements of the channel for the passage of the coolant, various finning steps, and various fin sizes.

Published: December 2018

The article presents recommendations for assessing the heat and energy efficiency of a design solution for a building envelope based on the calculation of energy costs during typical periods of time. The recommendations are based on the analysis of defects in thermal protection of building envelopes during design and construction, by studying design documentation, thermal imaging, calculation and verification of building envelope components. Results of calculation of temperature in hazardous structural sites for the design winter conditions with the help of software that implements the finite element method are presented. In the present paper, the design solutions of the nodes of the walls of residential buildings are considered, where, during thermal imaging, thermal bridge are visible through the external walls. It is shown that the using of multilayer brick walls in the apartment houses in a sharply continental climate is irrational due to the rapid deterioration of the properties of the insulation layer. Also, the thermal protection of buildings is influenced by the design solution defects and violation of construction technology.

Authors: Gryaznova Elena
Published: December 2018

Underground development project activities for structures located below existing level of groundwater can cause changes in hydro-geological conditions on the construction site and adjacent territories and lead to development of unfavourable engineering-geological processes. Article presents results of hydrogeological forecast at the construction site with foundation pit enclosed in diaphragm wall. To recreate existing hydrogeological conditions and to create accurate model, inverse problem was solved with a multivariate selection of the filtration parameters of the modeled system in such way that there was a satisfactory alignment of modeled groundwater levels and groundwater levels marked during well-drilling, and analytical data, acquired during analysis and compilation of existing hydrogeological data. Upon solution of inverse problem to replicate existing hydrogeological conditions on the model, a series of forecasting tasks was undertaken to assess the impact of planned construction on hydrogeological situation of the construction site and adjacent territories. Construction was modelled in a multi-variant setting for a completely impermeable diaphragm wall and a permeable diaphragm wall with coefficient of filtration of 0.005 m/day. It is advisable to provide a comprehensive hydrogeological and geotechnical forecast at the design stage as it helps to predict how changes in hydrogeological regime affect deformation behaviour of surrounding buildings.

Authors: Osipov Yuri , Safina Galina , Galaguz Yuri
Published: December 2018

The filtration problem of a suspension in a porous medium is relevant for the construction industry. In the design of hydraulic structures, construction of waterproof walls in the ground, grouting the loose soil, it is necessary to calculate the transfer and deposition of solid particles by the fluid flow. A one-dimensional filtration problem of a monodisperse suspension in a porous medium with a size-exclusion capture mechanism is considered. It is assumed that as the deposit grows, the porosity and admissible flow of particles through the porous medium change. The solution of the initial filtration model and the equivalent equations are calculated. For the numerical calculation of the problem, both standard first-order finite difference formulas and more accurate second-order schemes were used. The obtained solutions are compared with the results given by the TVD-scheme.

Pressure distribution and cavitation in counter-vortex flow energy dissipators of hydraulic spillways
Authors: Orekhov Genrikh
Published: December 2018

The article is devoted to the study of cavitation phenomena of counter-vortex flow energy dissipators that can be used in hydraulic spillways. The spillways providing the surface flow transitionn at hydraulic structures are equipped with energy dissipators of the discharged flow. An increase in the effective pressure on the hydropower project leads to an increase in the flow velocities and, hence , to an increase in the loads acting on the structures. One of such a manifestation is cavitation and cavitation erosion associated with it, which can lead to destruction of structures. The objective of the study consists in determining the cavitation characteristics of counter-vortex flow energy dissipators. The study was carried out by modeling using high-head physical models. The counter-vortex method of excess flow energy dissipation based on the work of viscous friction forces allows the flow energy to be dissipated in a very short part of the flow conductor system of the spillway. This feature of the counter-vortex flow energy dissipator imposes special requirements to the study of cavitation phenomena. The carried out studies resulted in obtaining the distribution of pressures lengthwise the flow conductor system of the energy dissipator with spiral swirls. The values of the cavitation coefficient and relative pressure at different points of the device are given. In the conclusions it is noted that the most dangerous part from the viewpoint of cavitation orrurence is the initial section of the flow energy dissipation chamber; cavitation due to flow separation and bubble cavitation occur within the flow and does not affect the structural elements; on a large-scale model working for 500 hours at pressures of up to 70 m cavitation erosion of the walls has not been detectd.

Published: December 2018

CT156, Geotechnics and civil engineering, has been developing efforts to create standards with the generic designation EN ISO 17892, Geotechnical investigation and testing - Laboratory testing of soil. The recent publication of EN ISO 17892-part 6, Fall Cone Test which describes in detail the use of this test method to estimate the undrained shear strength of cohesive soils leads to the necessity for the laboratories to get familiar with this test method and to acquire the required sensibility to analyse the results obtained. Originally designed to determine the liquid limit of fine soils, for which purpose it is considered as an accurate substitute of the Casagrande method, the method may constitute an alternative to the direct shear test, which takes certainly longer time to be carried out and is more complex. The present work aims to compare the values for liquid limit obtained with the Casagrande's method and the cone method and as well as the use of this test to estimate undrained shear strength, correlating with results from other laboratory tests such as the Direct Shear Test and the Laboratory Vane Test on remoulded samples. The results obtained show that there is a good correlation between the applied test methods for determination of the liquid limit and that, for some water contents, the results obtained by the three test methods are comparable.

Moscow program of renovation of housing in the context of inter-party competition
Authors: Andreev Igor
Published: December 2018

The most prominent social-economic project started by the Moscow administration in 2017-2018 is the Housing Stock Renovation Program. The main political parties represented in the capital offered the citizens their interpretations of the initial variant of the program and the suggestions on its improvement. The author compares the potential of the political parties in the capital's and the federal authorities, shows the main aspects of the cross-party cooperation and competition regarding the legal documentation of the best, to their mind, variant of the program. The author also investigates the interconnection between the political parties and the civil society and, particularly, the specifics of the mass street protests, where the Muscovites expressed their ambiguous attitude to the renovation program. The author concludes that so called «systemic» parties showed a high level of the cooperation, in the process of which they were able to develop mutually acceptable amendments to the initial variant of the renovation project and to document them in the relevant legislative acts. It is also important that the parties were able to widely inform the citizens on the essence of the project, to get acquainted with the public opinion regarding this issue through various «feedback» channels, and to weaken the state of anxiety experienced by a part of the society to some extent. The author supposes that during the implementation of such programs nationwide, it is reasonable to consider not only the mass experience of their normative-legal documentation but also the mechanisms of achieving the cross-party consensus demonstrated in Moscow as well as the interaction with the civil society on the solution of the relevant problems of social-economic development.

In consideration of the actual needs, 1300 °C was selected for the heating temperature of flue gas. When the billet was taken out from furnace, the billet core temperature were about 1200 °C, and the temperature difference between the billet surface and core fluctuated between 10 to 50 °C. At the same time, in order to ensure the quality of billet and save energy and cost, the heating temperature and oxygen concentration in furnace should not be too high. Increasing the oxygen concentration led to higher heating rate due to lower level of the inert gas (N2) in the combustion air. When the oxygen concentration was increased from 21% to 36%, the heating rate of flue gas was increased by 68.3% in the heating test, and the heating rate of billet core was increased by 39.5%. Higher oxygen concentration yielded higher flame temperature. Hence, the NOxconcentration increased with increasing oxygen concentration. Moreover, the generation of NOxconcentration was faster and more under the excess oxygen at higher oxygen concentration levels. The NOxconcentration is very low and the highest NOxconcentration is only 27.2 ppm even at the highest oxygen concentration under flue gas cycle combustion conditions. Under the graded oxygen combustion and concentrated oxygen combustion conditions, the higher the oxygen concentration, the greater the difference in NOxemission concentration. The concentration of NOxin the graded oxygen supply is relatively low. Additionally, Numerical Simulations indicated that the temperature distributions became progressively nonuniform with increasing oxygen concentration because the absorption coefficient and convective heat transfer coefficient were altered.

This work deals with the influence on Zircaloy-4 of annealing in the β domain and subsequent quenching in view of extrusion. The effect of the size of the prior β grains on the microstructure is investigated. The results indicate that for prior β grain sizes up to 1.6 mm, the β quenched Widmanstätten microstructure is distributed between “parallel platelets” and “basket-weave”. However, sizes larger than 2 mm promote the formation of “basket-weave”. Double annealing in the β domain leads to the formation of large prior β grains with no need to anneal for a long time. Indeed, protracted annealing may lead to exaggerated growth. Efficient double annealing requires some conditions: rate of cooling after the first β annealing a few °C.s−1 (air cooling), heating rates of 1 or 2 °C.s−1 during the second rise in temperature. The second cooling should be somewhat quicker (possibly 12 °C.s−1 and above) to obtain the thin, intricate lamellae favored for extrusion.

Breast cancer, the most common in women, is a cancer of good prognosis. During this last decade, the improvement of cancer screening and treatment has significantly increased disease-free and overall survival. However, the chemotherapy, especially based on anthracyclines, and targeted therapies like trastuzumab have a toxicity to the cardiovascular system. If physical exercise is recognized as beneficial in tertiary prevention, especially by reducing fatigue, improving the physiological capacities of exercise, muscle strength and ultimately quality of life, conversely, few data are available on the effects of exercise on treatment-induced cardiotoxicity. This review, based on the PubMed database, presents the results of preclinical and clinical studies showing that physical exercise, by its cardioprotective role, increases the antioxidant capacity, reduces oxidative stress, maintains the left ventricular ejection fraction at a normal value and improves diastolic functions during and after treatment. Regular physical exercise should be an integral part of supportive care in oncology but it is necessary, in future studies, to determine its modalities for a better prevention of the cardiotoxicity of the treatments.

Indikation Im Not- oder Brandfall sind Patienten in Krankenhäusern durch ihre eingeschränkte Mobilität extrem gefährdet. Bei einigen Großbränden in mehrstöckigen Krankenhäusern kam es in der Vergangenheit zu Todesfällen.

Methode Wir haben daher eine Evakuierungsmatratze entwickelt, welche die Funktionen eines Evakuierungstuches bereits beinhaltet, jedoch mit dem Liegekomfort einer normalen Matratze. Die Halte- und Fixiergurte sind geschützt vom abwaschbaren Matratzenbezug verborgen und lassen sich im Ernstfall durch Reißverschlüsse erreichen. Mit einer Person kann ein Patient aus dem Bett, über den Flur und durch das Treppenhaus gezogen werden, ohne sich zu verletzen. Die kompletten Matratzen sind ca. 80 – 90 € teurer als die normalen Matratzen. Inzwischen sind alle Betten in den 6 Krankenhäusern unseres Verbundes mit den Matratzen ausgestattet.

Schlussfolgerung Eine schnelle Rettung lässt sich somit mit einem Komplettsystem ermöglichen.
Leben im Gleichgewicht

„Das Leben ist kurz, aber die Kunst ist lang, die rechte Zeit ist nur ein Augenblick, Erfahrung trügt, Entscheidung ist schwer. Man muss nicht nur selbst das Rechte tun, sondern auch der Kranke und die dabei sind, und das, was von außen kommt“. – so lautet der erste und wohl berühmteste dem großen Arzt Hippokrates zugeschriebene Aphorismus. So ist es nicht von ungefähr, das uns schon die alte hippokratische Textsammlung dazu anhält, Luft, Wasser und Ortslage und darüber hinaus vieles andere mehr in Zusammenhang mit der Gesundheit zu bedenken. Über Jahrhunderte war in Ergänzung dazu die Humoralpathologie die bestimmende medizinische Lehre – eine auf innere und äußere Gleichgewichte bedachte Herangehensweise. Zu Recht haben wir uns von gelber und schwarzer Galle, Blut und Schleim als Determinanten von Gesundheit und Lebensqualität verabschiedet. Dennoch bleibt der Grundgedanke vielfältiger innerer und äußerer Gleichgewichte als Grundlage körperlicher, seelischer und sozialer Gesundheit, oft unter anderen Namen, weiter wirksam: als Homöostase und Normalwerte in Physiologie und Biochemie, als balancierter Flow Kanal in der Stressforschung, als Balance von Risikofaktoren und Schutzfaktoren in der Resilienzforschung und auch im zukunftsorientierten Gedanken einer Koproduktion von Gesundheit in einem gelingenden interaktiven Miteinander von Therapeut, Patient und psychosozialer Umwelt: „Man muss nicht nur selbst das Rechte tun, sondern auch der Kranke und die dabei sind, und das, was von außen kommt“…
