Authors: Yang Changhui , Du Yu
Published: November 2020

Distributed generation can not only improve the utilization level of energy, but also bring huge economic and environmental benefits, which is conducive to the sustainable development of economy and society [1]. With the expansion of distributed generation scale and the implementation of market-oriented trading pilot, it is necessary to accurately evaluate and analyze the economic and environmental benefits of distributed generation, so it is necessary to establish an accurate evaluation model to guide grid companies and government departments to better develop and utilize distributed generation technology. As a whole, the connection between distributed generation and large power grid is helpful to save investment, reduce energy loss and give full play to their respective advantages. From the perspective of distributed generation project, it is helpful for investors to construct cost, invest reasonably and quote accurately. The benefits of distributed generation access to power grid mainly include reducing line loss, reducing power construction cost, reducing electricity price, delaying the construction of distribution and transmission cost, and improving environment and climate.

Published: November 2020

Aiming at the wind abandonment problem of CCHP “determining electricity by heat”, this paper proposes an optimal scheduling method that takes into account the coordination of source and charge of the integrated energy system of wind power. Introduce a ground source heat pump on the source side, use wind power for heating, and decouple the CCHP’s “constant heat” operation constraints; use the price demand response on the charge side to assist wind power grid integration; finally, consider the coordination of source and charge to establish an integrated energy system. The upper layer adopts the electricity price demand response to guide users to respond to changes in wind power output. The lower layer considers the role of ground source heat pumps and determines the optimal output of each unit with the minimum total system cost in the dispatch cycle. The full text is solved using Matlab software. The calculation example shows that this method effectively improves the wind power consumption capacity of the system, reduces the system operating cost, and has good social and economic benefits.

Authors: Kong Lingxiao , Miao Dejun , Guo Zhengxing , Jiang Jiachen , Cheng Yingmo
Published: November 2020

In order to reduce the deposition of dust on the surface of the fin of the air cooler, the influencing factors of dust deposition were studied. Firstly, the airflow along the working face is observed, which provides variable reference and data support for the wing dust deposition experiment. Then, the dust collecting test platform was built to simulate the dust collecting on the air cooler fins. Finally, the key factors that affect the dust deposition on the fins are studied by controlling the variables. The results show that the condensate water plays an important role in the dust deposition of the air cooler fins in high temperature and high humidity environment. When the amount of condensed water is less, the condensed water is adhered to the surface of the fin, which has the effect of adhesion to the particles, thus speeding up the deposition of dust on the surface of the fin. When the amount of condensed water is large, the condensed water moves downward under the action of gravity and carries away the dust attached to the fin surface, thus slowing down or even reducing the deposition of dust on the fin surface.

Published: November 2020

Based on big data analysis, for the actual operating data, the method of dividing non-uniform working conditions was studied to obtain typical data of different working conditions. The traditional sliding pressure curve is only a shortcoming of the single value function of the load. Convolution neural network is applied to build a nonlinear model of load, main steam temperature, reheated steam temperature, ambient temperature and main steam pressure. And then, the real-time optimized value of the main steam pressure is obtained. After verification, the model is proved to be satisfactory in both precision and regularity. Finally, the main steam pressure optimization model is applied to the actual 300MW thermal power unit, and closed-loop control is performed. The results prove that the application of real-time main steam pressure optimization can effectively reduce the energy consumption of the unit, and have higher energy saving potential at different ambient temperatures.

Effects of Plants and Plant Fermentation Broth on the Removal and Characteristics of Dissolved Organic Matter in Self-Supplying Carbon Source Constructed Wetlands Treating Secondary Effluent
Authors: Yu Tingting , Guo Wenrui , Zhang Mingxiao , Wen Yue
Published: November 2020

In this study, four constructed wetlands (CWs) were developed. The effects of plants and plant fermentation broth on the removal and characteristics of dissolved organic matter (DOM) were evaluated. As the ratio of added COD to influent nitrate (CODAdd/NO3-N ratio) increased from 0 to 4, the DOC removal rate increased from 0.48 to 5.41 g m−3 d−1 in the unplanted microcosms, and from 0.75 to 5.73 g m−3 d−1 in the planted ones. The presence of plants could increase the DOC removal rate from 0.48–5.41 g m−3 d−1 to 0.75–5.73 g m−3 d−1. This indicated that both the addition of plant fermentation broth and planting could greatly improve the DOC removal during the CW treatment. Moreover, adding plant fermentation broth introduced highly aromatic compounds into the microcosms, and thus increased the UV254 and SUVA values of the effluent. The plants could lower the effluent UV254 value through improving the removal of aromatic compounds, but it increased the SUVA value by increasing the proportion of aromatic compounds in total DOMs.

Published: November 2020

Based on the calculation of density functional theory, the adsorption and dissociation of NO on Pd (111) surface were systematically studied. The results show that the most stable adsorption mode of NO was at fcc site with N-terminal downward, followed by hcp site and top site; Bader charge and charge density difference analysis show that there was obvious charge transfer between NO and Pd(111) surface; the analysis of density of states further indicates that there was obvious chemical interaction between them; the dissociation barrier of NO on Pd(111) surface is 2.45eV, which indicates that NO is easy to poison Pd metal surface. Finally, the two dissociation pathways of NO adsorbed on fcc site indicate that NO is very difficult to dissociate on Pd (111) surface.
Slope instability judgment criteria in FEM based on strength reduction method
Authors: Peng Xiaogang , Li Jia , Li Youzhi , Jiang Jian
Published: November 2020

The correct judgment of the instability state affects the reduction coefficient obtained by the strength reduction finite element method, and then affects the calculation result of the safety factor. Taking the Griffiths slope as an example, the Abaqus software was used to calculate the instability criteria using three types of criteria: non convergence of numerical iteration, sudden change in displacement of characteristic parts, generalized plastic strain or equivalent plastic strain penetration. The results show that there is a corresponding relationship between whether the numerical calculation is converged and whether the slope is unstable. When the calculation is terminated due to non-convergence, the strength reduction coefficient does not change much, and the setting of the finite element convergence condition has little effect on the result. Therefore, it is recommended to use finite element calculation for convergence as a basis for determining slope instability.

Authors: Chen Nuo
Published: November 2020

Fluoroquinolone antibiotics (FQs) have a good bactericidal effect on a variety of bacteria, and are widely used in the treatment of various diseases. Due to the low residue and high stability in foods and water environment, it is difficult to detect FQs. Magnetic molecular imprinted technology (MIT) is specifically used for detection and identification, and magnetic molecular imprinted polymers (MIPs) are obtained by combining modified magnetic materials with polymers with specific molecular recognition cavities, which not only improves the ability to select and recognize specific template analogs, but also enables rapid separation. This review summarizes the research progress of MIPs with natural magnetic materials, magnetic nanomaterials and magnetic molecular sieve materials as carriers according to the cost, points out the advantages and current problems of each magnetic material, and describes the current status and development prospects of magnetic MIPs.

Published: November 2020

Taking automotive glass regulator (glass regulator for short) as investigative object, fatigue life of glass regulator in top dead center locked-rotor condition is analyzed by adopting the combined simulation of ABAQUS and FE-SAFE. Firstly, calculation criterion of fatigue life of glass regulator and the combined simulation steps of analyzing fatigue life of glass regulator are investigated. Afterwards, HYPERMESH is used to generate mesh of glass regulator and ABAQUS is used to finite element analyze glass regulator. Then, stress condition is obtained. Finally, stress condition, material fatigue property, loading spectrum are imported into FE-SAFE for analyzing fatigue life, and fatigue life nephograms are gained. Fatigue life nephograms suggest that fatigue life of plate curved part on slider, flanging on guide rail, the part near the mounting hole of guide pulley are short, on which risk of fatigue failure exists. This method provides theoretical basis for design of fatigue life of glass regulator.

Authors: Zhou Yangyuan , Wang Li , Guo Pengfei , Yao Guodong
Published: November 2020

Gamma(γ)-valerolactone (GVL) which can be produced from carbohydrate biomass has been regarded as one of the most promising platform chemicals because it can be converted to liquid alkenes adapted for transportation fuels. In the producing process, GVL was synthesized via hydrogenation of levulinic acid, which was obtained from acidic hydrolysis of carbohydrate biomass. Generally, gaseous hydrogen was employed as hydrogen source in the hydrogenation reaction. However, highly pure and high-pressure gaseous hydrogen faces high risk of hydrogen storage, transportation and operation. Moreover, due to the need for activating the gaseous hydrogen, noble metal catalysts were commonly used, limited the large-scale application. Some liquids, such as formic acid, alcohol and water, can act as hydrogen donor under cerain conditions. Liquid hydrogen source possesses safe and high efficiency advantages in the hydrogenation process. This paper highlights the recent progress in the production of GVL with liquid hydrogen source.

NaN3, as a kind of rich-nitrogen energetic material, engaged in the synthesis of hierarchical transition metal (Co/Ni) organic framework materials (MOFs) through a facile hydrothermal reaction, during which aqueous N3
− function groups being as an unique ligand in preparation of novel coordination polymer with the existence of Co2+ (or Ni2+) salts and dicyandiamide. The obtained compounds (Co-eMOF, Ni-eMOF, NiCo-eMOF) were characterized by structure and composition analysis, specific surface area, thermogravimetric analysis (TGA) and crystal X-ray diffraction. The prepared products regardless of the metal cautions (Co, Ni, or coexist Co and Ni), perform a well three-dimensions (3D) nanostructures with spherical shaped monoliths, known as organic framework materials. The as-prepared products with developed porosity demonstrate a high surface area in range of 80∼130 m2/g. XRD patterns for these three examples show similar lattice crystalline, which to an extent matches well with the simulated MOF-74 materials, suggesting profound formation of oriented crystal growth. XPS reveals the compounds all equipped with high nitrogen content (54∼60 at%), which is largely hinging on the contribution from N3
− function groups, suggesting the superiority of NaN3 serving as the rich nitrogen precursor. Accounting for extensive application, we will apply this as-prepared (Co/Ni) MOF materials as one kind of nitrogen-rich precursor and conduct them for further calcination treatment for preparation of graphite-based transition metal carbides (TMC), and it is highly anticipated to achieve efficient activity towards electrocatalysis in our follow-up actions.

Published: November 2020

Standardised test manoeuvres are used to identify the manoeuvrability of a vessel. Currently, most of these tests are unsatisfactory to properly judge the manoeuvring capabilities of an inland vessel which sails in different environments than the seagoing ships for which these tests were initially designed. Moreover, inland vessels tend to have non-conventional propulsion systems and configurations which further decreases the adequacy of these standardised tests. Therefore, this study investigates the inland-applicability of these existing standardised test manoeuvres. In addition, this study suggests three new manoeuvres: (i) the Counter Thrust Test, (ii) the Sine Angle Test, and (iii) the Simultaneous Zigzag Test. In order to validate the suitability of these tests, an autonomous inland cargo vessel performed two of these suggested manoeuvres, (i) and (ii), and one existing manoeuvre, named the Crabbing test. The data of these experiments show fruitful insights in the wide range of manoeuvring capabilities of the examined inland vessel, which the standardised tests would not have uncovered.

Application of wavelet analysis for processing tomograms of narrow cracks
Authors: Likhachev A , Zerkal S , Likhachev N
Published: November 2020

The previously proposed method of increasing the visibility of cracks on tomograms obtained from X-ray sensing of sections of metal elements of building structures has been developed. A multiscale decomposition of tomogram lines is performed using the Haar wavelet basis. The detailed decomposition coefficients corresponding to the level of the assumed crack width are multiplied by a constant, the value of which is determined based on the noise level and the difference between the amplitude of the crack image and the surrounding background. In contrast to the previous work, where these parameters were assumed to be set, here we suggest the methods for its evaluating from the measurements. In particular, a simple formula is obtained that relates the variance of uncorrelated noise in the projection data to that of noise in the tomogram. The method is implemented as a computational algorithm based on which a computer program is developed. Numerical modeling was performed. The errors of the first and second kind were used toevaluate the effectiveness of the method determining whether a pixel belongs to a crack image. Binary classification was used for their calculation. Dependences of errors on the number of projections and the noise level on them were obtained. The results of the simulations showed that the use of the proposed method can reduce errors by 1.7-2.5 times.

Published: November 2020

In recent years, the approaches to address the issue of whether an object is real estate have been developed, but this problem has not received a legislative solution, which, both is associated with a two-level system of real estate, land plots and objects; and the modern needs of civil real estate turnover and the interests of its participants. All these make it necessary to fix at the legislative level more and more new real estate objects, including complex infrastructure objects. The article deals with the issues of information support for infrastructure real estate objects that arise, conducting accounting and registration actions. It is shown that the most optimal model for accounting and registration actions in relation to a complex infrastructure object is the unified real estate complex (UREC) model, based on complex cadastral works. The purpose of the study is to consider the issues of information support for infrastructure real estate objects, for the analysis of accounting and registration actions and for identifying new opportunities and optimal solutions in the Unified State Register of Real Estate in order to provide consumers with fast and high-quality public services.

Published: November 2020

The physical essence of the “nagel effect” for main reinforcement in a spatial crack of reinforced concrete structures under the action of bending and torsion for the model of reinforced concrete structures deformation involves the formation of the first block and the second block of a spatial crack. The second block is located on the upper surface of the longitudinal reinforcement to the surface of normal stresses and the resultant force from crushing concrete and a special adhesion force to the surface of the reinforcement (and the additional effect of breaking the continuity) in the eccentricity to its center of the axis of the reinforcement for distributed variable bending moment (through the calculation of statically indefinable systems for the force method). It is important to allocate a special area of the left side for the longitudinal reinforcement in the first block of separation and the formation of a new longitudinal crack, which removes surface normal and tangential of stress adhesion. Consider the scheme-a beam with two fixed ends: to calculate it, take the main system obtained as a result of making a cut in the middle of the beam for given unit diagrams of bending moments: under the action of a vertical load; with linear displacements of the fixed ends (normal to the beam axis); with rotations of the fixed ends in construction mechanics.

Published: November 2020

Digital transformation influenced not only economic branches and markets, but also people’s quality of life in different regions of the country. The purpose of the research is to evaluate people’s digital quality of life and to define its interconnection with investment capabilities of Russian regions. The authors measure digital component of people’s quality of life with a regional index including six subindices (digital skills of people, availability of digital goods for people, digital quality of working life, social sphere and services, state electronic services and safety of people informational activities). These subindices based on data from the regions of the Russian Federation were used to define the level of people’s life digitalization and to estimate the digital inequality with the application of R/P ratios and variation ratios during 2015 – 2018. This period corresponds to available data on information society and digital economy in Russian statistics. For all years of the considered period the first position is taken by safety of people informational activities and the last place belongs to digital quality of working life, social sphere and services. Digital inequality, based on four subindices, increased during 2015 – 2018. Results of research obtained with the use of econometric methods show complete or partial confirmation of connection: it is positive for investment potential indicators and the Russian regional index of digital component of people’s quality of life and its subindices. Government expenditures on the digital economy program in Russia have the worst result among other national projects. During the process of digitalization it is desirable to unite government investments, household expenditures and firm investments in order to improve regional programs performance and cope with possible disproportions.

The desire to be “modern” in the formation of sacred space, which follows from the artistic decisions of the first consumers of steel and concrete in sacred buildings, is analyzed. The constructive advantages and disadvantages of new materials are revealed. Metal constructions and decorative elements that form a sacred space are presented. A comparative analysis of public spaces, both sacred and secular in terms of the use of metal structures. Possibilities of new materials which demanded aesthetic comprehension are presented. It was found that during the XIX century such comprehension in the architecture of sacred spaces took place in line with two approaches: traditional-aesthetic, when constructive elements made of new material were designed in traditional historical forms in line with the eclectic understanding of styles; and structural and technological, by inventing new design principles for new construction. It was found that in both cases the use of metal and reinforced concrete was a significant factor that influenced the formation of modern sacred space.

Published: November 2020

The technology of mineral disclosure, based on the electrohydraulic effect, allows splitting the host rock along inhomogeneities, i.e. along the boundaries of inclusions of particles of useful minerals, leaving the degree of grinding within the limits of economic feasibility. The aim of the study was the experimental development of electro-hydraulic technology for energy-saving selective disintegration of finely disseminated ores of complex mineral raw materials. Research was conducted using a specially designed laboratory setup. As objects of research, previously crushed samples of various ores were used. The subject of the study was the process of the discovery of minerals from the action of factors of the electrohydraulic effect. Approaches to the calculated determination of electrical parameters that provide a high degree of mineral disclosure are described. As a result of a series of experiments on the discovery of minerals, the high efficiency of the proposed technology was confirmed.

Published: November 2020

In recent years, two-dimensional MXenes have been emerged as potential electrode materials for rechargeable batteries due to their unique properties such as exceptional safety, significant interlayer spacing, environmental flexibility, large surface area, high electrical conductivity, and excellent thermal stability. This review examined all of the recent advances in the field of MXenes and their composites (hybrid structures), which are found to be useful for the electrochemical applications of advanced rechargeable batteries. The main focus of this review is on metal-ion batteries and lithium–sulfur (Li–S) batteries. It is intended to show that the combination of recent improvements in the synthesis and characterization, greater control of the interlayer distance, and new MXene composites, together serve as an emerging and potential way for energy storage applications.

Published: November 2020

Droplet-Based energy harvesting is one of the most recent techniques used to convert environmental mechanical energies into electrical energy. Despite unique properties like compatibility with MEMS fabrication and efficient performance in reduced spaces, their operation is limited by the negative effects of electrowetting. In presence of an external electric filed, the wetting state of a droplet can be a function of three factors: the properties of applied dielectric, the wettability features of the droplet, and the amount of applied electric filed. An appropriate circuit can manage the effect of external electric filed on the droplets which here is considered as a tool to mitigate the negative effects of electrowetting. This paper presents designing, modeling, and fabrication steps of a droplet-based power generator considering electrowetting during fabrication and evaluation processes. The generator operation was analyzed in a voltage-constrained circuit and the experimental data were in accordance with the proposed semi-empirical model in this regard. Generator evaluation was done using a range of capacities made by 12 to 84 droplets under frequencies of 0.8, 10.8, and 16.6 Hz and a bias voltage of 7.5 V. The maximum output voltage and power was obtained by applying 16.6 Hz frequency to 84 droplets, reaching 1.25 V and 1.56 μW, respectively.
Modelling non-linear consensus dynamics on hypergraphs

Published: November 2020

The basic interaction unit of many dynamical systems involves more than two nodes. In such situations where networks are not an appropriate modelling framework, it has recently become increasingly popular to turn to higher-order models, including hypergraphs. In this paper, we explore the non-linear dynamics of consensus on hypergraphs, allowing for interactions within hyperedges of any cardinality. After discussing the different ways in which nonlinearities can be incorporated in the dynamical model, building on different sociological theories, we explore its mathematical properties and perform simulations to investigate them numerically. After focussing on synthetic hypergraphs, namely on block hypergraphs, we investigate the dynamics on real-world structures, and explore in detail the role of involvement and stubbornness on polarisation.
Solid-state dewetting of silver-thin films: self-assembled nano-geometries
Authors: Sultan M T , Manolescu A , Svavarsson H G , Valfells A
Published: November 2020

The study presents the dynamics of solid-state dewetting of silver (Ag)-film annealed in N2 ambient, analyzed by atomic force microscopy and scanning electron microscopy. Varying the annealing parameters (i.e. temperature and time) and Ag-film thicknesses were taken into account, to determine their effect over the solid-state dewetting of Ag-films. Several morphological evolutions from nanohole to the presence of metastable nanorings were observed. It was determined that structures annealed at high temperature (≥900 °C) and/or time (≥2 h) results in formation of metastable nanorings and whose geometrical aspects and population grew with increasing film thickness. Possible applications of the structures for fabrication of silicon nanowire arrays and photo-emitters are briefly described.
Religion: A Very Short Introduction
Authors: Tweed Thomas A.
Published: November 2020

Religion: A Very Short Introduction offers a concise and fair account of the vast topic of religion, incorporating insights from different scholarly fields while also respectfully representing diverse religions and varying viewpoints. Everyone who aspires to be an informed global citizen needs to understand religion, since it affects how billions around the world conduct their lives. But most overviews are too wordy or too partisan. This one focuses on the key questions: What is religion? What does it do? How is religion expressed and how has it changed? That story of change begins with the first signs of religion among ancient humans using stone tools, and it ends with modern adherents using computer technology. Religion continues to evolve, and it continues to play an important role in how people deal with recent trends and contemporary problems, from climate change to armed conflict. Religion, the author shows, is both intensifying and alleviating those problems. Religion is pulling us apart and bringing us together.
