Authors: Vasilieva A G , Kuznetsova M V , Zinovyeva E G , Ivashina N S , Kuznetsova N V
Published: April 2022

The article discusses the current state of the hemp growing sub-sector and innovative directions for the use of hemp products in Russia. At present, there is a steady trend of increasing industrial crops of industrial hemp with the parallel creation of capacities for its primary and deep processing. The analysis of the state of modern hemp growing shows that after the decline in hemp production during the Soviet era, interest in this crop has increased in the last decade, in connection with which there is an increase in the sown area of industrial hemp (11 times from 0.87 thousand hectares in 2010 to 10.2 thousand ha in 2019), an increase in gross harvest (by 3.16 times from 1.038 thousand tons in 2011 to 3.289 thousand tons in 2020). The largest cannabis region in Russia is the Ivanovo region. Today in Russia there are about 10 companies that are engaged in the processing of hemp. The current problem of hemp growing is the lack of modern domestic hemp harvesting equipment, which has not been produced in Russia for many years, and the widespread use of imported equipment is constrained by its high cost. In this regard, the development and implementation of specialized equipment of domestic production is an urgent task in the development of hemp growing. Opportunities for the further development of hemp growing are government support measures. Currently, there are a number of financial instruments, the effective use of which will stimulate the development of hemp growing and increase the investment attractiveness of the sub-sector.

Authors: Sarapulova G I
Published: April 2022

As a result of field and laboratory studies, ecological diagnostics of coastal soils was carried out in 11 points of the city of Irkutsk along the coastline of the Angara River in the recreation zone for 5 km. Revealed alkaline soil with pH up to 9.0. An increased sulfate content was found in the aqueous extract of soil substrates. This leads to soil toxicity, especially as a result of the subsequent transformations of sulfates into more toxic compounds -hydrogen sulfide, sulfuric acid and insoluble metal sulfates. Indicators of the biological activity of soils revealed a decrease in the activity of soil enzymes. More than 70% of soil samples were found to be toxic. The parameters of the biogeochemical state of soils indicate the inhibition of the enzymatic process. The inverse dependence of the biological activity of the soil on its pH has been established. The distribution of total forms of heavy metals Pb, Cu, Zn, Ni, Cd, Hg and As at observation points is obtained. The excess of the normative contents of elements was revealed. The studies carried out have shown an increased environmental hazard of the recreation area in the city center and the need for environmental protection measures.

Authors: Semerenko S A , Bushneva N A
Published: April 2022

The article presents the research results on the effect of lime mud (lime fertilizer from sugar beet waste during processing) in doses of 3.9 and 5.9 t/ha on the yield and infestation of sunflower sowings with the beetle larvae of the Elateridae family. We carried out the research in 2016-2018 at V.S. Pustovoit All-Russian Research Institute of Oil Crops (Krasnodar, Russia). We established that lime mud applied 30 days before crop planting resulted in a significant decrease of wireworm population from 15-21 to 6-10 specimens/m2. Recording of plant density at the stage of full sprouts showed considerable thinning of sowings due to pest damage; in the control variant, it reached up to 80 % whereas plant death under fertilizer application at the doses of 3.9 and 5.9 t/ha was 42 and 32 %, respectively. The application of lime mud at a dose of 3.9 t/ha resulted in the highest increase in yield - 0.58 t/ha. The oil content of sunflower seeds in the experiment was 48.9-52.1 % but we noted the decrease of this indicator in the variant with the lime mud at a dose of 3.9 t/ha. Oil acid value was at the same level in both variants (3.9 and 5.9 t/ha) of lime application and reached 1.5 mg KOH.

Sludge pits of biological treatment plants and their reclamation
Authors: Yu Teplykh S , Gridneva M A , Dremina E V
Published: April 2022

The paper describes different methods of sludge pits reclamation and biological methods of their purification. It shows that sludge pits purification becomes possible due to sludge dewatering and its membrane composting. Membrane composting at the moment helps solve different problems. The main danger lies in the fact that sludge pits pose a potential threat to water bodies pollution and are also a source of pathogenic microbiological pollution, as well as a source of unpleasant smells and harmful gases (methane, hydrogen sulfide, mercaptan, carbon dioxide, etc.). Excessive pressure, semi-permeable membrane shells and optimization of oxygen content are able to minimize this harmful effect. As a result of these procedures, silt and sludge turn into technical soil with a humidity of 40-50%, which can be used as a backfill. It is often used to restore recreational areas and to set out various plants as well. Due to its high content of phosphorus and nitrogen sludge is a very good fertilizer.
Modern climate warming, dynamics and development of new plots of bird areas as population adaptation to anthropogenic landscapes of Eastern Siberia
Authors: Mel’nikov Yu I
Published: April 2022

The article discusses the features of the formation of new plots of the areas for birds in the anthropogenic landscapes of Eastern Siberia under the conditions of modern climate warming. It is emphasized that at the initial stages of this process, the warming was not intense and hardly noticeable (the beginning of the 19th - the first half of the 20th centuries). However, already at that time there was a clear trend towards the expansion of bird areas to the north and east. This process has progressed as the trend towards climate warming intensifies. In the second half of the 20th century, some typically western bird species reached Eastern Siberia. At the same time, extensive and prolonged droughts in the east of Central Asia caused a strong counter flow of dispersing birds to the west and north. In a number of bird species, mixing of the streams of dispersing birds was observed, and often these were closely related species. This indicates the formation of gaps in their once common areas that arose during periods of sharp cooling in previous climatic epoch. In the middle of the 20th century, the anthropogenic development of Eastern Siberia was very high. This facilitated the movement of birds of open landscapes far north. This fact is also emphasized by the oncoming flows of birds settling to the east and west as a result of severe and prolonged droughts in Central Asia. The birds of these streams crossed the Baikal rift zone (the northeastern zoogeographic boundary) and went far to the north - to the Central Yakut lowland and the tundra zone. The data obtained show that the development of new territories by birds and the expansion of their areas is associated with intense climate warming. The development of the territory by man only contributed to the movement of birds to new regions, due to the formation of more suitable habitats for birds (open and mosaic landscapes). Consequently, the intensification of climate warming, coinciding with the expansion of bird areas to the north, indicates that it was warming, and not intensive development of the territory by humans, that played the leading role in this process. The entire process currently observed is the adaptation of birds to the dynamic conditions of the new climatic period.

Formation of a system of intelligent analysis of geological data based on ontological engineering
Authors: Dadykin V S , Strizhakova E N , Strizhakov D V , Shevchuk A V , Yazvenko N A
Published: April 2022

This article discusses the relevance and options for using the tools of ontological modeling, in relation to the objects of the mineral resource complex. Currently available geological information resources are consistently converted into electronic form, which creates a significant array of electronic scanned copies of documents that must first be translated into electronic text (recognition operation), and then analyze the electronic text for the presence of geological, economic, geological and technical parameters relevant for making managerial decisions in the field of subsoil use. The solution of the text recognition problem is relevant for quite “old” geological information resources, while the task of text analysis is relevant for each of them. One of the options for forming the semantics of interaction is ontology. It has a significant potential for application in various fields of knowledge, including in the field of geology and subsoil use. Ontologies allow integrating disparate data in order to form their thesaurus, which is especially necessary in geology, where the ambiguity of terminology interpretations creates significant barriers in the formation of ontologies of geological information resources. This problem is aggravated by a decrease in the number of specialized specialists in geological exploration organizations. The developed ontology is designed to form a knowledge base in the structure of geological information resources as the basis of a management decision support system in this industry.
Hypothesis of the formation of bacterial blights on secondary moistened cotyledons of soybean and other leguminous crops
Authors: Zelentsov S , Moshnenko E , Saenko G
Published: April 2022

The article examines cotyledonous bacterial blight – a possible causes of the decrease in seed sowing quality of leguminous crops. The article presents the hypothesis that there is another cause for the development of cotyledonous necroses, regardless of species, variety, and crop’s cultivation area. The secondary (rain) moistening of mature seeds leads to the development of cotyledonous necroses and a decrease in seed germination of soybean, white bean, chickpea, white lupin, and blue lupin due to the subsequent necrotization of over-moistened areas of cotyledon tissues. The secondary moistening of mature seeds can lead to the development of cotyledon necrosis and a decrease in germination of soybean seeds, white beans, chickpeas, white lupin and blue lupin due to subsequent necrotization of waterlogged areas of cotyledon tissues. The symptoms of cotyledon necrosis development during secondary moistening of mature seeds and cotyledonous bacterial blights are almost identical in all leguminous crops. Bacterial pathogens of various species and families are isolated on the dead areas of cotyledons. This fact can be explained by the repeated saprophytic infection of cotyledon sites.

Local food is a strategic product for fulfilling the needs of substitute staple for rice and also for food mainstay and a business commodity. One of the local food sources of alternative carbohydrates is breadfruit. Breadfruit production in Indonesia reaches to approximately 190,551.00 tons. Besides being used as food, breadfruit is also used as a raw material for the industry. It has a relatively high nutritional composition. In 100 grams of wet weight, breadfruit contains of 27.12 grams of carbohydrates, 17 mg of calcium, 29 mg of vitamin C, 490 mg of potassium and an energy value of 103 calories. The edible portion (flesh) of the young fruit is 70%, while the ripe fruit is 78%. Currently, the consumption of breadfruit is limited into form of boiled or fried one. Various technologies have been developed in order to increase the variant of breadfruit processed product as an alternative staple food besides rice, wheat and corn. Along with the times, breadfruit has been processed into various form of foods, in order to increase its value in society and be consumed as staple food. Several types of processed breadfruit that has been used as staple foods are breadfruit flour, noodles/vermicelli; bread, sponge; donuts; cakes; breadfruit chips; etc. The effort of processing breadfruit into various kinds of processed foods can support the development program of food diversification. Food diversification is an effort to increase the availability of various food and based on the potential of local resources to meet the diversity of food consumption patterns, which also nutritionally balanced and safe; develop food business; and/or improve the welfare of the community. This paper is the result of a summary and synthesis of several research and assessment results.

Published: April 2022

The quality of the water is very important in determining the aquaponics system, including the pH parameter such as the ideal acidity level in aquaponics. The water quality temperature parameter also plays a very important role in determining water quality, especially in the case of temperature changes that are influenced by air temperature, wind speed and solar radiation. A safe maximum level of ammonia (NH3) is required in a good aquaponics system. When making adjustments, the water quality is set manually without the use of a controller that is fed back to the actuator, that is, the manual change of the desired temperature, pH value and ammonia. Temperature changes are made by exposure to sunlight or heating, while ammonia is achieved by adding fish feed or adding new water. Whereas the pH treatment is done with vinegar (for a pH value that is too humid), bicarbonate is used for a pH value that is too acidic for the research object. Based on the aquaponic system literature parameter data for ammonia from less than 0.5 ppm to an ideal of 0 ppm, the pH value is in the ideal range of 6.5 - 8, while at the ideal temperature it is (21-28 ) ° C. In this study, the author develops a solution to monitor the state of water with pH, ammonia and temperature sensors based on the Internet of Things, the Arduino Uno uses as monitoring parameters, pH sensors are They use to detect the acid content of water, temperature sensors for temperature measurements, use the MQ135 gas sensor for ammonia. and ESP8266 as a WLAN interface to send data to Android without using actuators.

Published: April 2022

The growing demand for pineapple-based snacks offers very promising business prospects for fruit growers in Indonesia. This opportunity has been taken advantage of by many local farmers who grow this uniquely shaped fruit. To simplify the process of analyzing the quality of pineapples worth selling, machine learning assistance is needed. The factors that will be used for the calculations and analyzes that were previously performed manually by humans, should be performed with machine learning more quickly, efficiently, effectively and accurately. The author proposes the Naïve Bayes Classifier model as a classification method to demonstrate that the model has good accuracy, good precision, good recall and is good at classifying data. In this proposed model, the Naïve Bayes Classifier is a prediction technique based on simple probabilistic criteria and on the application of Bayes’ theorem with the assumption of strong independence. Therefore, this model is capable of producing high classification accuracy with low complexity with classification accuracy up to 75%, so this model can be efficient as an analytical tool.

The α, β-unsaturated aldehydes selective hydrogenation, especially the C=O bond, is an extremely challenging topic in the field of catalysis. In this paper, a series of pure TiO2 photocatalysts obtained at various calcination temperature were tested for the hydrogenation of citral. It has been determined that inexpensive TiO2 nanoparticles, calcined at 450 °C–500 °C for two hours, show hydrogenation selectivity of 100% from citral toward unsaturated alcohols (UA) with the highest conversion up to 99% under ultraviolet light. The present work reports a simple yet pragmatic approach for the efficient and selective hydrogenation of the C=O bond of citral.

Published: April 2022

Corrosion of steel rebars and susceptibility of reinforcement steel to chloride ion attacks are the two major problems for the construction industries and thereby a huge amount of money is spent to repair it. Epoxy coating on the steel rebars can be one cost-effective solution to alleviate the detrimental effects of corrosion in concrete structures. In the present research, plain and epoxy coated rebar (ECR) samples were chosen to study the correlation between microstructure, hardness and corrosion performance. The microstructures of the investigated thermomechanically treated (TMT) rebars primarily reveal tempered martensitic rings at the outer surface followed by a narrow bainitic transition zone in between along with a ferrite-pearlite microstructure at the inner core. The corrosion resistance of plain and epoxy-coated rebars in naturally aerated 3.5% NaCl and 1% HCl solutions were studied using gravimetric test, open circuit potential (OCP) test, and linear polarization monitoring techniques. It has been witnessed that the corrosion current (icorr) has been shifted towards lower values and polarization resistance (Rp) values are higher for ECR samples which is a clear indication of higher corrosion resistance of the ECRs than the plain rebars. Energy dispersive spectroscopy (EDS) analysis reveals the presence of iron hydroxides and iron oxides. However, x-Ray diffraction (XRD) analysis indicates the existence of various types of oxides, hydroxides, and oxy-hydroxides like iron chloride hydroxide [Fe2(OH)3Cl], goethite (α-FeO(OH)), lepidocrocite (γ-FeO(OH)), magnetite (Fe3O4) and bernalite [Fe(OH)3(H2O)0.25] in the epoxy coated rebar samples whereas, plain rebars indicate the presence of goethite (α-FeO(OH)), maghemite (γ-Fe2O3), magnetite (Fe3O4), hydrogoethite (Fe2O3.H2O), lepidocrocite (γ-FeO(OH)) and iron oxide (Fe21.34O32). All the experimental results confirm that ECR samples are more corrosion resistant under both acidic and saline environments.

In intervention surgery, DSA images provide a new way to observe the vessels and catheters inside the patient. Extracting coronary artery from the dynamic complex background fast improves the effectiveness directly in clinical interventional surgery. This article proposes an incremental robust principal component analysis (IRPCA) method to extract contrast-filled vessels from x-ray coronary angiograms. RPCA is a matrix decomposition method that decomposes a video matrix into foreground and background, commonly used to model complex backgrounds and extract target objects. IRPCA pre-optimizes an x-ray image sequence. When a new x-ray sequence is received, IRPCA optimizes it based on the pre-optimized matrix according to the strategy of minimizing the energy function to obtain the foreground matrix of the new sequence. Besides, based on the idea that the new x-ray sequence introduces new information to the pre-optimized matrix, we propose UIRPCA to improve the performence of IRPCA. Compared with the traditional RPCA method, IRPCA and UIRPCA save much time while ensuring that other indicators remain basically unchanged. The experiment results based on real data show the superiority of the proposed method over other RPCA algorithms.

Published: April 2022

The spreading effect of atmospheric pressure microplasma jets (APμPJ) on the surface of materials will increase the etching area, and controlling the diameter of the jet can improve the precision of surface treatment. In this work, a two-dimensional axisymmetric simulation model is established to analyze the effect of nitrogen (N2) shielding gas on helium (He) from gas dynamics. In addition, by etching the polyethylene terephthalate film, the relationship between the etching effect and aerodynamic analysis is verified. The simulation results are similar to the experimental results, indicating that N2 shielding gas has a focusing effect which is related to the N2 flow rate, distance difference between the inner and outer tubes, and outer tube nozzle diameter. It is hoped that the results of this work can provide a certain reference for the use of shielding gas to control the jet flow of APμPJ.

The resurgence of self-supervised learning, whereby a deep learning model generates its own supervisory signal from the data, promises a scalable way to tackle the dramatically increasing size of real-world data sets without human annotation. However, the staggering computational complexity of these methods is such that for state-of-the-art performance, classical hardware requirements represent a significant bottleneck to further progress. Here we take the first steps to understanding whether quantum neural networks (QNNs) could meet the demand for more powerful architectures and test its effectiveness in proof-of-principle hybrid experiments. Interestingly, we observe a numerical advantage for the learning of visual representations using small-scale QNN over equivalently structured classical networks, even when the quantum circuits are sampled with only 100 shots. Furthermore, we apply our best quantum model to classify unseen images on theibmq_parisquantum computer and find that current noisy devices can already achieve equal accuracy to the equivalent classical model on downstream tasks.

Published: April 2022

Origami patterns have previously been investigated for novel mechanical properties and applications to soft and deployable robotics. This work models and characterizes the mechanical and electrical properties of origami-patterned capacitive strain sensors. Miura-patterned capacitors with different fold angles are fabricated with a silicone body and foil electrodes. The planar strain sensitivity ratio is tunable from 0.2 to 0.5 with fold angles, while all-soft patterns demonstrate low mechanical tunability through fold angle. We conclude by offering recommendations for designing and modeling future origami-patterned soft material sensors.
Remaking Charles Dickens for 21st-Century Russia
Authors: Finer Emily
Published: April 2022

Charles Dickens’s writing entered the Russian cultural sphere only a year after he published The Pickwick Papers in England. In 1838, extracts from The Pickwick Papers appeared concurrently in different translations in several Russian journals. Canonical 19th-century writers and thinkers (including Nikolai Gogol, Vissarion Belinsky, Fyodor Dostoevsky, and Lev Tolstoy) read the novels in Russian, French, German, or English, either serialized in journals or as books. The popularity of Dickens in Russian translation was such that by the centenary of his birth in 1912 the third complete works—with new translations of all the novels—had been published. His stories of childhood were by then commonly excerpted and rewritten in magazines for Russian children. During Soviet times, Dickens increased in importance and was embedded in both official and private cultural spheres. His realism, his interest in poverty, and his own childhood experience of deprivation in London all rendered him suitable for retranslation for the new mass reader and for Soviet children, all of whom were to be furnished with negative portrayals of life under capitalism. Despite these propagandistic intentions, children and adults often identified with the suffering of Dickens’s child characters and found comfort in his reliable happy endings. In the Soviet Union, novels by Dickens typically held positive associations of warmth, safety, and moral consistency. They also offered inspiration for imaginative travel to a foreign country they could not dream of visiting in person. This convergence of official and personal appreciations of Dickens resulted in the publication of the most complete of complete works: thirty volumes of completely new translations supported by detailed scholarly apparatus. This so-called dark green edition was published in time for the 150th anniversary of Dickens’s birth in 1962, and a five-kopek postage stamp with a portrait of Dickens was issued in the same year. By the 2000s, a reading public who read Dickens as children in the Soviet Union could now read Dickens in English, on and offline, and even visit London for themselves. Two hundred years after Dickens’s birth, in 2012, the glossy Russian magazine Snob dedicated a special issue to Dickens with new commissions from notable writers including Eduard Limonov, Evgenii Popov, and Marina Stepnova. For the special issue’s editors, Dickens was less a representative of English culture than a conduit of nostalgia for their childhoods in the Soviet Union. At the same time, they noted that Dickens’s reception in Russia had come full circle: from the hypercapitalist publishing environment of Victorian London to the wild capitalism of Putin’s Russia.
