Stress Drop Variations of Induced Earthquakes near the Dallas–Fort Worth Airport, Texas
Authors: Jeong Seong Ju , Stump Brian W. , DeShon Heather R. 
Published: April 2022

Abstract
We estimate stress drops for injection-induced earthquakes near the Dallas–Fort Worth Airport in the Fort Worth basin (FWB), Texas, to investigate source properties in response to fluid injection. The stress drops for the Airport sequence show three unique characteristics compared to those estimated for other earthquake sequences in the FWB: (1) stress drops have lower mean and median values; (2) stress drops increase with moment magnitude; and (3) stress drops increase in size over the first 1.5 km in radial distance from the injection point. The low stress drop Airport events occurred shortly after the initiation of injection near a fault within hundreds of meters of the well. Pore pressure perturbations in the Airport area are 1 order of magnitude lower than those from the other sequences, suggesting that absolute pore pressure changes may not be the main factors of stress drop variations. We suggest that the low stress drop events may be related to transition from aseismic slip to seismic rupture previously observed in laboratory and field experiments.

Authors: Huang Ziwei , Lou Shaohong 
Published: April 2022

At present, there are two outstanding problems in the teaching of garment CAD in colleges and universities: one
is missing of parametric structure design function for garment CAD teaching software, the other is disconnection between
garment CAD and core professional courses. From the perspective of talent development and industry demand, teaching reform is
proposed: first of all, the curriculum of garment engineering drawing is established to introduce the general AutoCAD software for
engineering majors. Secondly, under the framework of “identical fusion” relationship, the curriculum group is constructed, which
contains two-dimentinal and three-dimentinal garment CAD, garment structure design, together with garment technology. The
reform mode has shown good teaching effect in practice.

Promising Russian developments in the production of flour products with flax seeds and products of their processing
Authors: Efremov D. P. 
Published: April 2022

The article is devoted to the systematization of scientific developments of domestic scientists in the sphere of oilseeds flax processing and their use in technologies of flour products. Oilseed flax is the only oilseed crop in which almost all anatomical parts are important for industrial processing. The use of oil flax in the food industry is due not only to the presence of biologically valuable nutrients, but also to the functional and technological properties inherent in the products of their processing. It is shown that along with whole and ground flax seeds, not only flax seeds processing products (full-fat, semi-fattened, skimmed and oil), but also bran and cryopowder from seeds are widely used in the above food technologies. Flax seed hydrocolloids or dry polysaccharide extract deserve special attention, which are of interest not only from the technological point of view (analog of xanthan gum, guar gum), but also from the medical and biological position, since they perform prebiotic function in the human body. Analysis of numerous domestic sources of scientific, technical and patent information allows us to conclude that flax seeds are, on the one hand, a well-known and widely used raw material. On the other hand, it should be noted that there are still a number of insufficiently elaborated directions, in particular, additional research is needed, which will allow to realize on an industrial scale economically competitive technologies of production of flour products, maximizing the potential (technological and medical and biological) of non-starch polysaccharides, lignans and other biologically active compounds of flax seeds

Published: April 2022

The paper considers the possibility of using highly dispersed modified aluminosilicates in the process of extracting hydrogen sulfide from wastewater. The problem of the presence of hydrogen sulfide in natural waters is due to the impossibility of using such waters in human household activities. Water with a high content of hydrogen sulphide has low organoleptic properties, is not suitable for consumption and is highly corrosive. Produced water generated in the process of oil production must also be treated. In the presence of hydrogen sulphide in the produced water, further water injection into the reservoir is highly discouraged, as this can lead to "plugging" of oil-bearing channels. In this regard, the work proposes a method for extracting hydrogen sulfide from natural and waste waters. The work synthesized a new adsorption-coagulation material based on modified aluminosilicates (bentonite clays) using salts of multivalent metals. The possibility of creating a reagent with a different ratio of aluminosilicate matrix: modifier is considered. It was found that the efficiency of the reagent increases with an increase in the pH of the medium. The activity of the reagent in relation to hydrogen sulfide, clarification and removal of oil products was studied. The capacity of the reagents obtained as a result of the modification can reach 32 mg/g in terms of hydrogen sulfide. In the reagent, it is possible to vary the ratio of aluminosilicates and modifiers, which can facilitate the use of the most effective reagent, depending on the conditions. The reagent is capable of extracting not only hydrogen sulfide, but also oil products from the processed aqueous solutions. The reagent binds hydrogen sulfide into insoluble forms, after which the precipitate can be separated from the solution and disposed of.
Research of ostrich fat properties when melting in electrochemically activated medium

Published: April 2022

In recent decades, there has been a growing scientific interest in various kinds of technologies using electro-activated solutions with high reactivity and representing a powerful toolkit for intensification of production processes. However, theoretical knowledge about the regularities of change in fat properties during melting in an electrolyte is rather fragmentary, scarce and often contradictory. The work is devoted to the study of the main factors influencing the change in physical and chemical properties and yield of fat in the process of melting using catholyte, to substantiate the feasibility of its use and develop an industrial line for obtaining fat. The object of studies was ostrich fat obtained by traditional method – by melting in water and by experimental technology – in catholyte as well as technological regimes of fat extraction. According to the data obtained, the fat melted at pH of catholyte 11, temperature 100 and 75 °С was characterized by low values of acid number – 0,45 mg KOH/g and 0,40 mg KOH/g, respectively. The opposite trend was observed with a successive decrease in the alkalinity of the ECA medium and an increase in the melting temperature of the fat, which led to an increase in the content of secondary oxidation products in the experimental samples. It was found that due to the high reactivity of the EСA medium, the temperature and pH of the catholyte increased, the intermolecular interaction within the fat phase decreased, which increased the mobility of lipid molecules relative to each other. The lowest values of fat viscosity (0,42 and 0,4 kPa?s) were recorded when treating fatty raw materials in catholyte with pH 10.5 and 11 and temperature 100 °С. It is shown that increasing the pH of the catholyte contributes to minimizing the values of peroxide number of ostrich fat, in contrast to the heating temperature. It is established that processing of raw materials in catholyte at 75 °C resulted in the yield of fat 88,4–90,1%, which is almost 1,4 times higher than when melted in water. In the wet method of mellowing in water, denaturation of protein structures and a higher degree of fat extraction can be achieved at a mellowing temperature above 75 °C, in contrast to the proposed method of processing raw materials.

Published: April 2022

The article is devoted to the development of a mathematical regression model of the beet pulp pressing process carried out on on a deep press extruder. The following parameters of beet pulp pressing were taken as initial ones: initial moisture content (before the extruder) and final moisture content (after the extruder); sugar content in the pulp before and after pressing; sugar content in the pulp; beet chips length before and after pressing; total biological contamination of sugar beet pulp; pulp acidity before and after pressing; acidity of the granulated pulp. The Fuzzy Logic Toolbox module included in the MatLab package is used to implement the proposed technique. The Surfase Viewer module is used to present the simulation results in a graphical form. Such studies were previously carried out with the CurveExpert 1.3 application package. The resulting equations adequately describe the change in the sugar content in the pulp and its nutritional value depending on the pulp acidity and moisture content, as well as the length of the sugar beet chips. The significance of the influence of each of the main technological parameters (acidity and moisture content of the beet pulp, the length of the beet chips) on the amount of sugar in the pulp and its nutritional value was determined in the work. The resulting quadratic dependences having sufficiently high coefficients R2, adequately describe the process of beet pulp pressing in a deep press extruder with an assessment of the influence of variable parameters on the content of residual sugar and feed units in beet pulp. The data obtained make it possible to objectively evaluate the work of a deep-pressing exstruder and justify the kinematic mode of the screws rotation, which allows minimizing the cost of finished products.

Published: April 2022

On the basis of official statistical data on the structure and existing risks of the formation of Russia's foreign trade turnover in comparison with other developed countries, the objective need for import substitution has been substantiated, the acceleration of which and an increase in the role in ensuring the country's economic growth depends not only on the effectiveness of measures taken by the state and the business community, but and from a clear quantitative assessment of its performance. A comprehensive assessment of the effectiveness of import substitution was carried out on the basis of a wide range of statistically reliable single indicators reflecting the impact of import substitution on the state and dynamics of development of the most important sectors of the national economy – its domestic production, exports, imports, and the socio-economic sphere. In order to model and calculate a complex indicator of the effectiveness of import substitution on the basis of the formed system of single indicators, the method of principal components was used, implemented in the Statistica application software package and which made it possible to compress the generated array of multidimensional information to a limited number of more informative features (the main component for each block of indicators) up to the final a comprehensive indicator of the effectiveness of import substitution. The indicators that have the greatest impact on the effectiveness of import substitution in each block of indicators have been identified. Based on the regression analysis, a high positive correlation was found between the integrated indicator of the effectiveness of import substitution and economic growth. Using the method of multicriteria optimization, the parameters of import substitution have been determined, which, in real economic conditions, at the prevailing rates and scales of GDP, enhance the positive impact of import substitution on economic growth.

<span id="docs-internal-guid-1b269b4f-7fff-5a10-7710-69c82c89d0ab"><span>ASEAN Plus Three Emergency Rice Reserve or APTERR is a rice bank cooperation between ASEAN member states as well as China, South Korea, and Japan (as +3 or Plus Three). This collective commitment is made in order to ensure food security, particularly in the form of rice, in their member countries. Initiated due to the crisis that occurred from 2007 to 2011, APTERR is now facing the global COVID-19 pandemic that has been going on for more than one year. This, of course, presents a threat to the availability of rice due to limited mobility in the production or distribution sector, while the needs of rice in the community remains the same. In this paper, we will discuss further efforts and actions that have been taken by APTERR in assisting ASEAN members who are in an emergency status in their availability of rice. The research method which this paper used is a literacy review method, which will provide facts related to the background of APTERR, problems that threaten the threat of rice in the ASEAN region, and the latest presentation data to answer whether or not the APTERR plan will succeed in overcoming this pandemic crisis.</span></span>

Gas Slippage in Microscale Fractures of Partially Saturated Shale of Different Matric Potentials
Authors: Cheng Pengju , Yu Qingchun 
Published: April 2022

Summary
The gas slippage phenomenon in microscale fractures is extremely important to better understand subsurface gas flow in many engineering activities in shales, but the effects of water on gas slippage and the gas ﬂow process have rarely been investigated. In this study, two shale samples, each with a single fracture, were obtained to investigate gas slippage in partially water-saturated microscale fractures. A new experimental approach for monitoring gas slippage in partially saturated fractures of different matric potentials is presented. The fractures were moistened to different matric potentials in an environment under a certain confining pressure and in the presence of both water and gas, and the gas permeability at different gas pressures was measured with the steady-state flow method under five different matric potentials. The experimental results suggest that water in microscale fractures greatly reduces the gas permeability by one to three orders of magnitude and that capillary condensation is the primary mechanism underlying the observed dramatic decrease. The gas permeability decreases with increasing matric potential, and this relationship is quantitatively described. The pressure dependence of the gas permeability indicates that gas flow in the partially saturated fracture manifests strong slippage. Without considering the effect of gas slippage, the gas permeability obtained by continuum hydrodynamics prediction is overestimated by up to 15–20 times. Gas slippage is enhanced with increasing matric potential, and the corresponding relationship can be expressed with an exponential function.
