Direct production of a genetically-encoded immobilized biodiesel catalyst
Authors: Heater Bradley S. , Lee Marianne M. , Chan Michael K.
Published: August 2018

The use of immobilized enzymes as biocatalysts has great potential to improve the efficiency and environmental sustainability of many industrial processes. Here, we report a novel approach that allows for the direct production of a highly active immobilized lipase within the bacterium Bacillus thuringiensis. Cry3Aa-lipA crystals were generated by genetically fusing Bacillus subtilis lipase A to Cry3Aa, a protein that naturally forms crystals in the bacteria. The crystal framework significantly stabilized the lipase against denaturation in organic solvents and high temperatures, resulting in a highly efficient fusion crystal that could catalyze the conversion of triacylglycerols to fatty acid methyl ester biodiesel to near-completion over 10 cycles. The simplicity and robustness of the Cry-fusion crystal (CFC) immobilization system could make it an appealing platform for generating industrial biocatalysts for multiple bioprocesses.
The energy and mass balance of a continental glacier: Dongkemadi Glacier in central Tibetan Plateau
Authors: Liang Liqiao , Cuo Lan , Liu Qiang
Published: August 2018

Understanding glacier mass balance (MB) change under global warming is important to assess the impact of glacier change on water resources. This study evaluated the applicability of a modified distributed surface energy balance model (DSEBM) with 3–h temporal and 100-m spatial resolution to the alpine Dongkemadi Glacier (DKMD) in the central Tibetan Plateau region, analyzed the causes of glacier MB variations with respect to energy balance, and evaluated MB changes under various climate scenarios. Results showed that: (i) the modified model can describe surface energy and MB of XDKMD well; (ii) net shortwave and longwave radiation, accounting for more than 80% of total heat flux, dominated the glacier energy balance during both summer and winter months; (iii) summer MB spatial patterns dominated annual MB, consistent with the fact that DKMD is a summer accumulation type glacier; and (iv) effect of increase in air temperature on glacier MB is higher than that of decrease in air temperature. The sensitivity of MB revealed by the modified DSEBM can help to understand MB changes influenced by the climate changes and to regulate water management strategies to adapt to climate changes at the catchment scale.

Published: August 2018

It was hypothesized that supplementation of omega-3 fatty acids could increase physical activity (PA) levels, where traditional interventions often fail. The aim of this double-blind, randomized, placebo-controlled trail was to evaluate the effects of 15-week administration of omega-3 fatty acids on objectively measured PA and relative body weight in 8–9 year-old children. The children were randomly assigned to supplementation of omega-3 fatty acids or placebo. Primary outcome was change in PA counts per minute (cpm), and secondly change in body mass index standard deviation score (BMI SDS). Covariance models were applied adjusting for age, gender, weight status, PA and intervention season. Compliance was controlled for by analyzing fatty acid composition in plasma. The intention to treat population consisted of 362 children (omega-3 n = 177, placebo n = 185). No significant effects of omega-3 fatty acids on PA or relative body weight were observed. In covariance models no effects were observed by gender, weight status or change in PA (all p > 0.05), but inactive children increased their PA more than children classified as active at baseline (p < 0.05).

Context. Multiplanet systems are excellent laboratories to test planet formation models as all planets are formed under the same initial conditions. In this context, systems transiting bright stars can play a key role, since planetary masses, radii, and bulk densities can be measured.

Aims. GJ 9827 (K2-135) has recently been found to host a tightly packed system consisting of three transiting small planets whose orbital periods of 1.2, 3.6, and 6.2 days are near the 1:3:5 ratio. GJ 9827 hosts the nearest planetary system (~30 pc) detected by NASA’s Kepler or K2 space mission. Its brightness (V = 10.35 mag) makes the star an ideal target for detailed studies of the properties of its planets.

Methods. Combining the K2 photometry with high-precision radial-velocity measurements gathered with the FIES, HARPS, and HARPS-N spectrographs we revised the system parameters and derive the masses of the three planets.

Results. We find that GJ 9827 b has a mass of Mb = 3.69−0.46+0.48 M⊕ and a radius of Rb = 1.58−0.13+0.14 R⊕, yielding a mean density of ρb = 5.11−1.27+1.74 g cm−3. GJ 9827 c has a mass of Mc = 1.45−0.57+0.58 M⊕, radius of Rc = 1.24−0.11+0.11 R⊕, and a mean density of ρc = 4.13−1.77+2.31 g cm−3. For GJ 9827 d, we derive Md = 1.45−0.57+0.58 M⊕, Rd = 1.24−0.11+0.11 R⊕, and ρd = 1.51−0.53+0.71 g cm−3.

Conclusions. GJ 9827 is one of the few known transiting planetary systems for which the masses of all planets have been determined with a precision better than 30%. This system is particularly interesting because all three planets are close to the limit between super-Earths and sub-Neptunes. The planetary bulk compositions are compatible with a scenario where all three planets formed with similar core and atmosphere compositions, and we speculate that while GJ 9827 b and GJ 9827 c lost their atmospheric envelopes, GJ 9827 d maintained its primordial atmosphere, owing to the much lower stellarirradiation. This makes GJ 9827 one of the very few systems where the dynamical evolution and the atmosphericescape can be studied in detail for all planets, helping us to understand how compact systems form and evolve.
Exploring the bulk of the BL Lacertae object population
Authors: D’Ammando F. , Giroletti M. , Rainó S.
Published: August 2018

Aims. We are studying an unbiased sample of 42 nearby (z < 0.2) BL Lacertae objects with a multi-wavelength approach. The results of Very Long Baseline Interferometry observations were presented in the first paper of this series. In this paper, we study the γ-ray properties of the sample.

Methods. We analyse data collected by the Fermi-Large Area Telescope (LAT) during its first 8.5 yr of operation in the energy range 0.1−300 GeV.

Results. We reveal 23 sources with a test statistic greater than 25 (corresponding to ~4.6-σ) out of 42, with 3 sources not detected in the third LAT active galactic nucleus (AGN) catalogue, and fluxes between 3.5 × 10−10 and 7.4 × 10−8 ph cm−2 s−1. The majority of the sources have hard spectra (Γ ≤ 2), with only four having values in the range 2.1–2.4. The three newly detected sources have fluxes in the range between 0.54 × 10−9 and 1.35 × 10−9 ph cm−2 s−1 and photon index 1.7–1.9. Among the 23 LAT-detected sources, 19 are included in the third catalogue of hard Fermi-LAT sources, with a spectrum that connects relatively smoothly from 0.1 GeV to 2 TeV. LAT-detected BL Lacs are more luminous on parsec scales with respect to non-LAT-detected sources and have larger core dominance according to the unified models.

Conclusions. The LAT-detected BL Lacs seem to be composed of a bulk of “classical” sources dominated by Doppler boosting and characterised by compact and bright radio emission as well as hard γ-ray spectra. Moreover, we have identified a possible population of low-luminosity BL Lacs not detected by LAT, lacking a VLBI core, and with a small Doppler factor. Furthermore, three LAT-detected sources show non-classical properties for γ-ray emitting BL Lacs (no evidence of relativistic jet, low Doppler factor in radio images, relatively low core dominance) and three other sources, while showing radio emission on parsec scales, are not detected in γ rays so far.

Context. Ionized outflows, revealed by broad asymmetric wings of the [O III] λ5007 line, are commonly observed in active galactic nuclei (AGN) but the low intrinsic spatial resolution of the observations has generally prevented a detailed characterization of their properties. The MAGNUM survey aims at overcoming these limitations by focusing on the nearest AGN, including NGC 1365, a nearby Seyfert galaxy (D ∼ 17 Mpc), hosting a low-luminosity active nucleus (Lbol ∼ 2 × 1043 erg s−1).

Aims. We want to obtain a detailed picture of the ionized gas in the central ∼5 kpc of NGC 1365 in terms of physical properties, kinematics, and ionization mechanisms. We also aim to characterize the warm ionized outflow as a function of distance from the nucleus and its relation with the nuclear X-ray wind.

Methods. We employed optical integral-field spectroscopic observations from VLT/MUSE to investigate the warm ionized gas and Chandra ACIS-S X-ray data for the hot highly-ionized phase. We obtained flux, kinematic, and diagnostic maps of the optical emission lines, which we used to disentangle outflows from gravitational motions in the disk and measure the gas properties down to a spatial resolution of ∼70 pc. We then performed imaging spectroscopy on Chandra ACIS-S data guided by the matching with MUSE maps.

Results. The [O III] emission mostly traces a kpc-scale biconical outflow ionized by the AGN having velocities up to ∼200 km s−1. Hα emission traces instead star formation in a circumnuclear ring and along the bar, where we detect non-circular streaming gas motions. Soft X-rays are predominantly due to thermal emission from the star-forming regions, but we manage to isolate the AGN photoionized component which nicely matches the [O III] emission. The mass outflow rate of the extended ionized outflow is similar to that of the nuclear X-ray wind and then decreases with radius, implying that the outflow either slows down or that the AGN activity has recently increased. However, the hard X-ray emission from the circumnuclear ring suggests that star formation might in principle contribute to the outflow. The integrated mass outflow rate, kinetic energy rate, and outflow velocity are broadly consistent with the typical relations observed in more luminous AGN.

Authors: Narezhnaya Tamara , Zvonov Ilya
Published: August 2018

The authors consider a relevant problem of preservation and improvement of the ecological situation in large and medium industrial cities. Recently the cities suffer because of the increasing pollution. While motor transport is being transferred to the electric power, expand application of renewable types of energy, the industrial enterprises present a great danger. Even though the enterprises throw out many substances to the environment, it would be wrong to estimate them only as a negative phenomenon. They work for people and for the economy of the state. Three integrated options, describing the most typical situations, in which there are production objects during functioning and development, are considered in the article. The most often found schemes of planning of the production territories, relating to industries, which are historically placed in the cities, are analysed. The mechanism of distribution of pollution in these territories is considered. The generalized measures for each option of reconstruction transformations are offered.

A description of five mathematical models of the water-retention capacity of soil is given, taking into account the hysteresis phenomena. A computational experiment was carried out with these models using data on sandy soil. The experiment consisted of: (i) tuning of the models (parameter identification) by the method of dot-approximation of experimental data on the main drying and wetting branches of the hysteresis loop using an optimizing algorithm; (ii) the predictive calculation of the scanning branches of the hysteresis loop; (iii) a comparison of the errors in tuning results and the predictive calculation using the Williams-Kloot criteria. The commensurate and sufficiently low errors in the adjustment of the models have been achieved. The differences in the calculation of the scanning hysteresis branches are revealed. The practical significance of the mathematical models presented is to ensure the calculation of precision irrigation rates. The application of such rates in irrigation farming will help to prevent excess moisture from flowing beyond the root layer of the soil under the influence of gravity and, thus, to minimize the losses (unproductive consumption) of irrigation water, fertilizers, meliorants and plant protection products, and also reduce the risk of groundwater contamination with agrochemicals and eutrophication of water bodies.

Published: August 2018

The system of space monitoring (SM) is of great importance, as a means of ensuring environmental safety. This system is based on remote sensing. The structure of SM is a distributed system. This system comprises independent data storage, system control, system of dynamic ratings, capacity and forecasting, control system, information system (IS) processing of monitoring data. As IS it is necessary to choose a geographic information system (GIS). IS monitoring refers to the problem-oriented system. These information systems include specialized databases models. All monitoring systems use sets of models, which allow building complex enterprise models. The peculiarity of the SM is the need to coordinate support of this monitoring and rate of the GIS capacity. Production Manager's decision is the impact on the object of monitoring. Results management and environmental data are received at the monitoring subsystem. Integration of SM and GIS monitoring has led to the creation of geoinformation space monitor (GISM). The operation of the system GISM is designed to provide a guaranteed result taking into account the capacity. Basis – the decision of the decision makers (DM). Therefore, an independent scientific and practical interest is the adequate mathematical model of DM.

Authors: Trukhina Natalya , Okolelova Ella
Published: August 2018

The article considers problems and prospects of development of energy saving technologies in construction. The possible directions of improving the construction of residential facilities with the aim of increasing their efficiency are considered, taking into account different technologies. The main emphasis is on the use of solar panels as one of the most effective ways of saving resources. The maximum level of heliotropia for the Central black earth region is determined. To increase the efficiency of the solar battery it is proposed to develop a rotary device that allows you to change the angle of the battery in the vertical and horizontal planes. The dynamics of rotation in the horizontal plane should depend on the time of day, in the horizontal – season. The article presents the problem of determining the speed of rotation of the solar battery in the direction of the solar azimuth and relative to the horizon during the day, allowing you to use a slewing device with maximum efficiency. Increase efficiency when using the rotary mechanism will reduce the number of solar batteries with the same capacity of electricity consumption. Also the problem of determining the optimal number of solar panels.

Published: August 2018

There are the great problems of the concrete for high voltage the transmission lines obtaining. One of them is the creation of reinforced concrete centrifugally spun transmission towers with enhanced reliability and durability for high-voltage transmission lines having voltage of 110-750 kV. The second problem is the creation of high-quality reinforced concrete foundations to fix overhead electric line lattice towers in the ground because more than 50% of operated reinforced concrete towers and foundations are in need of repair or were put into repair. A complex high-performance organic mineral admixture for tower bodies of high-voltage transmission lines is developed. The main components of the admixture are polycarboxylate polymere and silica sol. It insures increased compressive strength and tensile strength in bending, freeze resistance, waterproofing and corrosive resistance. The obtained positive results allow to reduce a compression zone width and a crack growth width. The paper can be useful for not only the transport construction but and for concrete obtaining with special properties at any fields.

Published: August 2018

The paper presents research results concerning charge composition development to produce environmentally safe acid-resistant ceramics on the basis of low-plastic clay of the Vladimir region possessing self-glazing effect. 5 wt. % boric acid, 5 wt. % lanthanum oxide and up to 5 wt. % electroplating sludge have been introduced into the charge composition as functional additives. Boric acid serves as a flux and a source acid-resistant and heat-resistant vitreous phase based on borosilicates, but compositions contained in the electroplating sludge are decomposed in the process of ceramics firing causing the formation of calcium oxide and heavy metal oxides, which additionally increase material acid-resistance and heat-resistance like lanthanum oxide. To receive the developed material, semidry pressing technology has been applied under the charge forming moisture of 8 wt. %, specific pressure of 15 МPа and one-stage firing at max temperature of 1050 °C. The research presents the testing results of ceramics principal operating properties and environmental safety. The developed material can be used in clinker and acid-resistant bricks and tiles production for masonry and tiling in aggressive environment like buildings foundations and bases, premises with high moisture, as well as in sewerage systems, chimneys and ventilation ducts.
A research of stress/strain condition of reinforced timber structures with natural weakenings
Authors: Shchelokova Tatiana
Published: August 2018

In recent decades building structures are faced with more serious demands in a broad sense of this term, but in this case the lumber quality is gradually lowered due to large volumes of consummation along with sufficient time, needed to reproduce a stock lumber. As a result, there is a need for a more detailed and in-depth study of the influence of low-grade wood defects on the work of wooden structures. One of the methods to improve characteristics of structures, made with low-grade lumber is a reinforcement of these. The objective of the research below is to determine a degree of influence of a cross-sectional natural weakenings (such as knots) to a stress/strain condition of reinforced timber beams. The main research methods are as follows: mathematical calculations, computer modeling in the software “Cosmos/M” and an experiment. The methodic of an experiment planning is based on the “Latin Squares” principle [1]. The square is designed for three primary factors, each of which consists of three variants. The results of the research work are shown in form of graphs and tables. The main conclusions made after the research: the deformation of the reinforced beams is from 15 to 20% lower, as compared with non-reinforced; crushing of reinforced beams with weakened cross-section takes place without a sharp state of a former because of a supporting influence of reinforcement in tensioned zone and reliable connection of reinforcement with wood, which is ensured by a glued joint until the crushing of the timber. The safety factor of reinforced timber structures varies from 3 to 5.07.
Sustainable and social quality of refugee housing architecture
Authors: Eichner Michael , Ivanova Zinaida
Published: August 2018

The article analyses the relationship between sustainable architecture, social integration of refugees and innovative urban development, unfolding the synergetic potential between these questions. The authors consider that a successful integration of migrants with different cultural background, education and income level can be best achieved through buildings and urban districts, designed according to international sustainable principles. Not less innovation, but more is the key to address global challenges for spatial development of cities of any scale. Today it is not the limitation of financial resources for refugee housing programs that poses a threat to social, balanced and economically successful development of housing environments in cities, but the lack of knowledge of sustainable planning principles and sustainable construction techniques. The authors conclude: Whereas in central Europe socio-cultural and environment-friendly strategies for cities are widely in place, eastern Europe, Russia and north Africa or the Middle East region has not yet implemented such strategies as short-and long-term planning instruments. The article presents the urban case study project for a sustainable urban extension of the city of Luxor (Egypt) by the architect M. Eichner, Professor at the German University in Cairo – GUC.

Use of modern construction machinery in the construction
Authors: Prochorov Sergey
Published: August 2018

In the presented article there will be discussed measures which allow to lower expenses for the maintenance of the machinery and which contribute to the increase of energy saving in general. To achieve these goals, it is proposed to apply modern methods of organizing and operation works, to use high-tech construction equipment, and also to form an optimal mechanization complex of building and construction works. The optimization criterion is the cost of work. When determining costs for the operation of construction machinery at the site, we take into account their energy efficiency, compare the options and manage the most efficient fleet of construction equipment. In the course of meeting the task, there were drawn conclusions which demonstrate that an integrated approach to the formation of machinery parks on the construction site allows to use the available resources more rationally, in order to improve the environmental component and improve the quality of construction work.

Published: August 2018

In the modern world, great attention is paid to the problems of preserving a comfortable and safe environment for future generations. The notion of "sustainable development" in the world and national economy, which implies such a consistent development, in which the condition of satisfying the needs of present generations is met without sacrificing the opportunities of future generations, has become particularly relevant. This United Nations concept involves a balanced approach to the environment. Undoubtedly, the most important place in this concept is occupied by resources, including energy resources. Taking into account the world trend and orienting national interests, the Government of the Russian Federation fixes the priority directions for the development of science, technology and technology. Among these directions there are following: "Rational nature management", and also "Energy efficiency, energy saving, nuclear energy". The analysis of tools promoting the implementation of the state policy on energy saving, energy efficiency and environmentally sustainable development (regulatory framework, international and Russian standards) has been analyzed. Key problems of energy saving and energy efficiency of the real estate are formulated. Recommendations for increase in energy efficiency of the residential real estate are developed.

The article gives a model description of the management processes of the investment activity of a construction company that develops and implements innovative construction projects in the conditions of an acute shortage of external investment resources. Optimization of the series of managerial decisions for the construction of algorithms for managing the innovation and investment activity of a construction enterprise was carried out taking into account the functioning of the investment flow management system: soft management, risk management, crash management. The schemes of restructuring the production, investment and innovative structures of the construction enterprise are proposed. An investment model for the implementation of a specific innovative construction project has been developed and a number of management solutions that meet this model have been identified and designed to neutralize the effects of external adverse perturbations. The application of management solutions of internal, medium and external contours to the management system of investment flows of a construction enterprise as a part of specialized series is substantiated.

Experience of the leading port industrial complexes indicated high socio-economic performance indicators. However, not every port becomes a basis for formation of a port industrial complex. In different countries, formation happens differently. According to the functional problems, Russian port industrial territories have a lack of development of managerial approaches to its formation and development. Overview of the development of Russian port industrial complexes shows that shortage of research on strategical management, including investment and institutional aspects, leads to an absence of methodological basis for engineering industrial port zones, as well as its strategical development. This requires detection of typical problems of the development of Russian and foreign port industrial complexes, definition of influencing factors, and systematization of managerial experience. During research process, methodology for system economic theory, which is best suited for a complicated territorial facility, was used. Such methodology considers interrelations among environmental, process, project, and object aspects. Namely, the problems of formation and development of port industrial complexes, as well as factors contributing to its growing potential, were identified and systematized in comparative order.

Authors: Kabanov Vadim
Published: August 2018

In the work of the object of study, organizational and technological reliability (OTR) is presented as the ability of the construction process to maintain a specified (design) value of the intensity of construction and installation works (CIW). The subject of the study is the scope of OTR. The use of the indicator "probability of achievement of the set values of intensity of CIW" for planning of growth of productivity of work is capable to significantly increase reliability of the planned development, including taking into account the last achievements of science and technology. The aim of this work is to consider options for modifying the intensity of CIW based on the specific OTR. To achieve the goal, we tackled the problem of assessing the influence of methods of curve plotting cumulative probabilities for the rate of change of intensity of construction, and also showed alternative plans for the growth of labor productivity taking into account OTR. As a result of the study, the author comes to the conclusion about the identity of the probability of achieving a given level of intensity of production of CIW and the duration of construction of buildings and structures. Examples of alternative planning of productivity growth taking into account OTR are considered. The influence of the construction method of the curve of accumulated probability on the growth rate of intensity of production of CIW is proved.
