Abstract
There are many methods of water treatment and wastewater treatment, this includes sorption filters with different loads, the use of reagents, but mechanical cleaning filters carry a heavy load. The correct selection of equipment assumes effective water purification and high-quality irrigation of crops. The article presents the results of modernization of structural elements of a hydrocyclone to improve the efficiency of irrigation water treatment. The modernization consists in the fact that an impeller with a bearing was additionally installed on the outlet of the clarified product, which increases the centrifugal force of the swirling liquid flow, thereby increasing the efficiency of cleaning irrigation water. After the cleaning process, a chemical analysis of the irrigation water was carried out, which showed that the proposed design of a hydrocyclone with an impeller effectively reduces the concentration of impurities in the irrigation water. The amount of impurities in the purified water decreased due to, increasing the centrifugal force of the swirling fluid flow, suspended solids decreased by 3 times, turbidity by 2.5 times, color by more than 29%.

Abstract
The features of the skin histology and the determination of the quality indicators of wool of young female Tsigai breed sheep are presented in the article. A positive correlation was found between the fineness of the wool and the live weight (p ≤ 0.05); between the shearing of natural wool and the fineness of the wool (p ≤ 0.05); between the shearing of natural wool and the live weight (p ≤ 0.05); between the washed wool and the fineness of the wool (p ≤ 0.05) and the shearing of natural wool (p ≤ 0.05). There is no reliable relationship between the fineness and the percentage of the washed wool shearing. However, the percentage of the shearing of washed wool is negatively related to the live weight (p ≤ 0.05), the shearing of natural wool. The greatest thickness of the skin was on the back and leg are 968.07 and 968.24 microns respectively. It is assumed that the skin regeneration occurs due to the cells of the basal layer. This is due to the fact that the thickness of the basal layer decreases in the following order: side-back-leg-neck, which correlates with the degree of exposure to damaging factors on these areas.

Published: January 2022

Abstract
The article considers the development of a control algorithm for the actuating links of a manipulator with a parallel-serial structure. The authors suggest a two-stage procedure for resolving the problem of controlling the robot operating body motion into a set neighborhood of the final state for a set time. The first stage covers the process of solving the problem of defining the manipulator generalized coordinates at the set coordinates of the operating body. Then the problem of determining the laws of the formation of reference influences for the actuators is solved, which ensures the movement of the working body in the vicinity of a given point. The technique for the synthesis of dynamic algorithms for stabilizing the effector relative to a given position and implementing the program paths is based on generating the control signals of actuators by solving the inverse dynamic problem using a control signal generation algorithm provided that deviations from the current program path values are the solutions of a second-order differential equation. The laws of change in control voltages are obtained. The results of numerical modeling are presented, confirming the efficiency of the proposed algorithm on the example of a specific manipulator.

Published: January 2022

Abstract
Structures made of thin-walled shells are widely distributed elements in the environmental protection systems. In this connection, it is necessary to develop their effective and refined calculation. The point of the shell of the environmental protection structures is considered with a plane load in the initial position, deformed after j loading steps (displacement vector) and adjacent after (j + 1) loading step. The displacement increments and their derivatives are taken as nodal unknowns. The displacement vectors of the inner point of a finite element are represented in the initial basis, and their components are approximated through nodal unknowns using Hermite polynomials of the 3rd degree. To determine the deformed state of the shell, the algorithm of the method of discrete continuation with respect to the parameter in the vicinity of a singular point is used, in which the increment of loading at the step is the desired parameter. Based on the obtained dependencies, a step-by-step calculation procedure is organized, which allows you to get correct results if there is a special point.

Abstract
The article describes the conditions in the agricultural crops cultivation, which greatly affect their productivity. One of the main problems is sparse seedlings. In this regard, it is necessary to use innovative technologies for the cultivation of melons and gourds, which reduce risks and increase their productivity. To solve this problem, the authors developed a technology for multi-depth row crops seedbed planting, which field tests were carried out in the fields of the Volgograd state agrarian university. In the course of the study, the distribution of seeds in the seedbed and the distance between the bunches were studied when sowing them into the soil under various operating modes of the seeding machine. At the same time, the dependence of the distance between seeds in the bunch and between the bunches on the speed of the seeding machine was established. The use of the bunch planting technology at different depths makes it possible to ensure a favorable temperature and humidity regime for seeds in compliance with all agrotechnical requirements.

Abstract
The research objective is design of the information technology for automated control system model synthesis for reducing the labour intensity of the digital machine model design by improving the control system information conversion tools. The structural-functional digital machine models are proposed for project development of robotic manipulator control devices. Application of the structural-functional digital machine models allows reducing labour intensity and project timing of robotic center control system design due to the cycle scheme conversion to intermediate representation, which is convenient for digital machine synthesis using the modern development tools. When applying the proposed structural-functional model a process engineer can rely on keeping all important technological process details and a programmer can avoid a large amount of errors when developing the device algorithms. The developed algorithm can be represented as state diagrams, which can be adapted for integrated scheme crystal as a digital machine using the specific tools of computer-aid design.

Authors: Kochetkova O V , Shiryaeva E V 
Published: January 2022

Abstract
The subject of dairy farming digitalization is relevant due to global factors such as population growth, climate change and food traceability needs. Negative impact of these factors on dairy farming efficiency and safety can be neutralized or significantly reduced by means of modern digital technologies introduction which are aimed at improving of enterprise environmental and economic sustainability, the effectiveness of planning, monitoring and control of animal habitat and health. Main reason for the low rate of dairy farming digitalization is that enterprise top executives are lacking clear understanding of how their organization should be transformed using modern information technologies. Problem could be solved by creation of the perspective enterprise architecture model “To Be” which relies heavily on modern digital technologies usage. System analysis and system engineering techniques, TOGAF architecture management methodology and ArchiMate architectural language are used to develop dairy enterprise architecture. Presented models allow to see digital enterprise of dairy production entirely, to demonstrate interaction of its individual architectural elements from strategy to infrastructure of the enterprise. New business opportunities, namely digital management of dairy farm and various electronic services provide real time monitoring of dairy livestock conditions, traceability, sustainability and efficiency of production processes.

Published: January 2022

Abstract
Tissue-engineered living machines is an emerging discipline that employs complex interactions between living cells and engineered scaffolds to self-assemble biohybrid systems for diverse scientific research and technological applications. Here, we report an adaptive, autonomous biohybrid pumping machine with flow loop feedback powered by engineered living muscles. The tissue is made from skeletal muscle cells (C2C12) and collagen I/Matrigel matrix, which self-assembles into a ring that compresses a soft hydrogel tube connected at both ends to a rigid fluidic platform. The muscle ring contracts in a repetitive fashion autonomously squeezing the tube, resulting in an impedance pump. The resulting flow is circulated back to the muscle ring forming a feedback loop, which allows the pump to respond to the cues received from the flow it generates and adaptively manage its pumping performances based on the feedback. The developed biohybrid pumping system may have broad utility and impact in health, medicine and bioengineering.

Authors: Kaykha M M , Dashtbayazi M R 
Published: January 2022

Abstract
In this study, mechanical behavior and microstructural evolution of copper sheets, produced by modified-constrained studded pressing (modified-CSP) as a severe plastic deformation (SPD) method, were investigated by experimental and numerical methods. A finite element model (FEM) was established to analyze distribution of equivalent total strain, distribution of equivalent plastic strain and residual stress for the complete first pass of the process. Local stress concentration was predicted by FEM. Also, copper sheets were deformed by the modified-CSP from the first to the tenth passes. The distribution of residual stress on the surface of the copper sheets was measured at each step of the process. Crack initiation and propagation were investigated by the non-destructive penetration test (PT). The residual stresses were predicted by X-ray diffraction (XRD) via sin2
Ψ method. The residual stresses were determined for the annealed and the first pass samples, +128.2 and +80.4 MPa, respectively. The maximum compression residual stress was −62.5 MPa for the tenth pass sample. The microstructural evolution including grain size and dislocation density of samples during the process were investigated by XRD pattern analysis. The average grain size had a significant decrease from ∼35

μ
m

to ∼76 nm for annealed sample and tenth pass of modified-CSP, respectively.

AbstractBackgroundEosinophilic granulomatosis with polyangiitis (EGPA) is a multisystem disorder commonly affecting the lung and skin, with cardiovascular involvement found in up to 60% of patients. We present a case of myocardial infarction with non-obstructive coronary arteries (MINOCA) as the initial presentation of EGPA.Case summaryA 52-year-old female with past medical history of asthma, recurrent sinusitis, and peripheral neuropathy presented to our hospital with chest pain, rash, acute vision loss, elevated troponin, and peripheral eosinophilia. Electrocardiogram showed no ischaemic changes and coronary angiography displayed normal coronary anatomy. On a subsequent visit, cardiac magnetic resonance (CMR) showed predominant focal anteroseptal and inferoseptal akinesis with focal sub-endocardial delayed enhancement, indicative of a myocardial infarction involving the septal branches of the left anterior descending artery. Due to the focal findings on CMR, peripheral eosinophilia, and rash, the patient was evaluated for EGPA. Rheumatologic workup and skin biopsy were suggestive of small vessel vasculitis. The patient was diagnosed with multi-organ EGPA, involving the coronaries, which was ultimately thought to be the aetiology of her MINOCA. Following steroid and monoclonal antibody therapy, the patient experienced notable improvement in her cardiac function at follow-up appointments.DiscussionThis is a unique case MINOCA as the initial presentation of EGPA. Considering the heterogeneous disease presentation of those diagnosed with MINOCA, utilization of CMR is essential to guide diagnosis and management of such patients.

AbstractReceptor-like proteins (RLPs) on plant cells have been implicated in immune responses and developmental processes. Although hundreds of RLP genes have been identified in plants, only a few RLPs have been functionally characterized in a limited number of plant species. Here, we identified RLPs in the pepper (Capsicum annuum) genome and performed comparative transcriptomics coupled with the analysis of conserved gene co-expression networks (GCNs) to reveal the role of core RLP regulators in pepper–pathogen interactions. A total of 102 RNA-seq datasets of pepper plants infected with four pathogens were used to construct CaRLP-targeted GCNs (CaRLP-GCNs). Resistance-responsive CaRLP-GCNs were merged to construct a universal GCN. Fourteen hub CaRLPs, tightly connected with defense-related gene clusters, were identified in eight modules. Based on the CaRLP-GCNs, we evaluated whether hub CaRLPs in the universal GCN are involved in the biotic stress response. Of the nine hub CaRLPs tested by virus-induced gene silencing, three genes (CaRLP264, CaRLP277, and CaRLP351) showed defense suppression with less hypersensitive response-like cell death in race-specific and non-host resistance response to viruses and bacteria, respectively, and consistently enhanced susceptibility to Ralstonia solanacearum and/or Phytophthora capsici. These data suggest that key CaRLPs are involved in the defense response to multiple biotic stresses and can be used to engineer a plant with broad-spectrum resistance. Together, our data show that generating a universal GCN using comprehensive transcriptome datasets can provide important clues to uncover genes involved in various biological processes.
