Abstract
Science-based management of forage ecosystems of arid and semi-arid territories and the fight against their degradation, carried out on the basis of systematic monitoring, assessment and accounting of their state and dynamics, are becoming actual state problems in Russia and Kazakhstan. As a result of studying, evaluating and agro-landscape-ecological zoning of territories of Siberia and Kazakhstan, creating databases of land resources and natural forage lands, using literary and stock data, the authors developed indicators of the state of forage ecosystems of arid and semi-arid territories. One of the most important ways to improve the effectiveness of assessments of the state and dynamics of degradation of forage ecosystems, as well as the most accurate diagnosis of negative processes is to solve the problem of creating and using a system of geobotanical and soil indicators of degradation of forage ecosystems. The full assessment of the state and development of the process of degradation of forage ecosystems can only be provided by using the entire system of indicators compiled on the basis of a combination of a number of main indicators of forage ecosystems. Geobotanical indicators of forage ecosystems include the following main indicators: change of plant communities, degradation of pastures, projective cover of indigenous and ruderal vegetation, productivity of natural pastures, etc. Soil indicators include: the area of allotments disturbed by erosion, the degree of destruction of surface soil horizons by erosion, the intensity of erosion, etc.

Mercury in the modern world is a global pollutant entering the environment as a result of human activities. Currently, there are a large number of territories in the world whose soils and reservoirs contain mercury in quantities that pose a danger to human health and the environment. However, the methods that are traditionally proposed for remediation may pose a risk of secondary mercury contamination and/or negative health effects for those involved in cleaning. Phytoextraction of heavy metals from the soil environment is currently considered as one of the most promising non-invasive methods of reclamation. However, this approach has limited effectiveness for cleaning soils and reservoirs. Chemically reduced phytoextraction can increase the efficiency of this process both by converting less bioavailable mercury compounds into bioavailable fractions in the soil, and by increasing the rate of metal transfer in plants. The paper presents the results of a screening study of various chemical additives to enhance the phytoextraction of mercury with white creeping clover (Trifolium repens L.). The results obtained showed a good potential for reducing phytoextraction for the first time studied S-containing complexion, in which the monoethanolamine salt of dithiobiacetic acid was used as a sulfur-containing chelant (MEDBA).
The reported study was funded by MUCTR according to the research project No. 3-2020-039.

Abstract
In order to study the possibility of suppressing mycoses with fumigation pyrotechnic compositions, biologically active compositions were developed based on compounds synthesized according to original methods in the organic synthesis laboratory of the Federal State Scientific Institution "All-Russian Research Institute of Phytopathology", synthetic fungicides from the azole group, as well as natural antimycotics from the polyene group obtained by microbial fermentation of Streptomyces bacteria, followed by extraction of supernatants and preparative column chromatography of extracts. Pyrotechnic compositions of fumigation action were developed, including active substances of biologically active compositions (23 … 46%), oxidizer (22…56%), combustible substances (15…56%), flame arresters (14…34%), phlegmatizers (6…20%) and baking powder (4…8%). The stability of complexes of synthesized compounds with putative cellular targets: ergosterol; ergosterol-dependent membrane Na+/K+-ATPases; 14α-demethylases controlling the conversion of lanosterol to ergosterol; and squalene-monooxygenases catalyzing the synthesis of squalene–epoxidase, a lanosterol precursor, was studied using computer modeling methods in the B3LYP/DZP approximation using the ChemCraft and FireFly software package. It was found that the synthesized compounds with nitro groups in the molecule selectively coordinate with the Na+/K+-ATPase membrane enzyme site responsible for phosphorylation and binding to ATP. It is revealed that the nitrogen atom of synthesized benzoxazines selectively coordinates with the iron of Gemma 14α-demethylase, and the binding energy of the complex is significantly lower than the coordination energy of iron with the cysteine residue of the protein matrix of the enzyme. It was fixed that the synthesized compounds at a concentration of 16-500 mcg/ml have fungicidal activity against test cultures Fusauium graminearum, Alternarium alternata, Bipolaris soraciniana, comparable to the activity of comparison drugs phytolavin and previcur. It was fixed that the samples of pyrotechnic charges of fumigation action developed in the laboratory of organic synthesis of the Federal State Scientific Institution VNIIF have fungicidal activity against the phytopathogenic fungi F. graminearum, A. alternata, B. soraciniana with an effective action of 23 … 69% of the test cultures. For wheat affected by the tested crops, the effectiveness of pyrotechnic charges was in the range of 12 … 31% of the death of test crops. It is revealed that the fumigation method of plant mycosis suppression implemented in this work, integrated with modern methods of medical chemistry, organic synthesis and classical methods of chemical treatment, is an effective innovative solution and can be used in the development of food security strategies.

Abstract
Based on the investigation and analysis of the brick-concrete and single-story houses in a rural area of southern Guangxi, the author established four different overall models of single-story house according to a certain proportion by ABAQUS-a software of finite element analysis, so as to analyze the seismic response of brick-concrete and single-storey buildings in this area under the action of 6-magnitude frequent earthquake. The results show that, under the action of 6-magnitude frequent earthquake, if the single-storey and brick-concrete house is built without reinforced concrete, its wood beam support or column support cannot reduce the stress concentration of the structure obviously;the displacement deviation between the top and the middle of the outer wall can be reduced when the wood beam is used as the support between the inner wall and the outer wall.

Abstract
In order to study the influence of the thickness of the rubber damping layer on the damping performance of the rock mass arch structure under explosive load, a finite element model was established based on the ANSYS/LS-DYNA dynamic finite element analysis software, and four rubber damping layers with different thicknesses of 0 m, 0.2 m, 0.4 m and 0.6 m are set between the rock mass and the lining. The fluid-solid coupling algorithm is used to compare and analyze the maximum effective stress, peak pressure and peak displacement of the outer lining dome, spandrel and arch foot elements. Numerical simulation results show that the maximum effective stress of the arch, spandrel and arch foot decreases after setting the vibration damping layer, and the arch foot reduces by more than 80%; with the increase of the thickness of the vibration damping layer, the peak pressure of the vault, spandrel and arch foot decreases, and the peak displacement increases. When the thickness exceeds 0.4 m, the damping and anti-blasting effect is not obvious, and the peak displacement tends to be stable; the vault is a strong response part, and reinforcement measures should be taken; comprehensive consideration of economic factors, it is recommended to set a 0.4 m thick damping layer.

Published: February 2021

Abstract
A reciprocating force loading test was performed of a single-layer shear-yield eccentric brace frame specimen, and the finite element model of stiffeners of several energy-dissipating beam segments with different spacing is established. On the basis of verifying the validity of the finite element analysis, a non-linear numerical analysis of its hysteretic performance is performed, and the bearing capacity, initial stiffness, stiffness degradation and energy dissipation capacity of different model structures are analyzed. Studies have shown that appropriately reducing the spacing of the stiffeners in the energy dissipating beam segments can increase the load-bearing capacity, initial stiffness and energy dissipation capacity of the component, but the residual stiffness of the structure can be reduced.
Analysis on dynamic eccentricity effect and torsional performance of steel reinforced concrete frame with special-shaped column
Authors: Hu Zongbo 
Published: February 2021

Abstract
Based on the seismic simulation shaking table test of steel reinforced concrete frame model with special-shaped column, the lateral-torsional vibration response, dynamic eccentricity effect and nonlinear torsion response law of the model structure are studied. The results show that, under the action of three-way earthquake, the Y-direction and X-direction horizontal torsion coupling phenomena occur in the high-order vibration mode of the model structure, and the accidental eccentric torsion has a light influence on the seismic performance of the special-shaped column structure which does not exceed the height limit. The nonlinear torsion analysis shows that the inter-storey displacement angle of the model structure is affected by floor position, eccentricity and ground motion intensity. As the eccentricity and seismic intensity increases, the inter-storey torsion Angle of the model structure increases constantly. In case the relative eccentricity is less than or equal to 0.5 and the peak acceleration is less than or equal to 0.62g, then the amplitude of the inter-storey torsion Angle of the model increases slightly; In case the relative eccentricity is more than 0.5, then the lateral-torsional coupled effect of earthquake response of the structure is obvious, and the influence of eccentricity on torsion effect of the model structure is more obvious. The results show that steel reinforced concrete frame with special-shaped column has good ductility and torsion resistance.
Study on performance-based seismic design theory
Authors: Wang Yujie 
Published: February 2021

Abstract
There are many other names for performance-based design, such as “performance based”, “performance evaluation”, “performance explicit standards” and “performance-based standards”. The so-called “performance-based” refers to the performance specified in the specification or the performance proposed in the specification. When designing the design method, the specification only specifies the target performance, and leaves the checking method to the designer. In other words, performance-based design is a technology to set reliable performance goals and achieve them through reasonable structural analysis methods.

Abstract
Recycled concrete is a product of the recycling of building materials. It has the characteristics of low cost and large demand, and its application in engineering is gradually expanding. However, there are still many unclear problems in the performance of recycled concrete in cold regions. In order to solve this problem, this paper puts forward the performance research of recycled concrete under low temperature condition, and designs the recycled concrete low temperature structure model through the ratio of recycled concrete materials and experimental construction. According to its indexes, the changes of its cryogenic antifreeze performance, compressive strength, stiffness stability and other aspects are compared and analyzed. The comparative experimental results show that when the air content of recycled concrete is gradually reduced, the insulation effect is reduced, the strength of recycled concrete is reduced, the frost resistance is also reduced, the durability and stability is poor, and the frost resistance is poor. With the continuous increase of displacement and load seismic force, the crack of recycled concrete gradually changes, the stiffness decreases faster, the stiffness degrades to a greater extent, and the low temperature seismic performance is poor.

Authors: Zheng Airong 
Published: February 2021

Abstract
Using mathematical statistics, we analyzed the influence of temperature and relative humidity during test on the results. The test data of geomembrane were obtained by changing the temperature and relative humidity ranging from 18°C to 25°C and from 50% to 70% respectively. The results show that under different temperature and humidity, the coefficient of variation of the maximum tensile test value is 8.0%∼17.4%, and the coefficient of variation of average value is 6.7%, which is poor in stability; the coefficient of variation of the test value of elongation at break is 4.7% ∼ 11.7%, and the coefficient of variation of average value is 4.6%, and the value increases with increasing temperature; the coefficient of variation of right angle tear strength is 6.0% ∼ 20.7%, and the coefficient of variation of average value is 6.4%; the coefficient of variation of puncture strength test value is 4.2% ∼ 7.3%, and the coefficient of variation of average value is 6.1%, and the value decreases with the increase of temperature. These results will shed light on analyzing the influence of temperature and humidity on the mechanical test results of geomembrane and determining a reasonable temperature and humidity control range for geomembrane testing.

Abstract
Tier III of Annex VI from MARPOL 73/78 about NOx emission control soon may be implemented at a global level. There are three potential methods to fulfill the Tier III. First is derating power, second is using gas as fuel, and the third one is installing SCR. This research deals with using CNG as diesel engine fuel. This initial study was occupied a single-cylinder diesel engine. Gas cannot burn inside conventional diesel cycles. Dual fuel technology also tends to reduce fuel efficiency compared with the conventional one. Therefore, the single-cylinder engine was modified its piston crown part to overcome both problems. The modification of piston crown geometry affects the engine compression ratio. Modify the conventional diesel engine to become the dual-fuel type is concluded as a potential technique to be developed. The study results show NOx reduction up to 33.68% and the fuel efficiency increase up to 1.512% without any disruption to the engine operating conditions.
