Published: September 2023

Abstract
The purpose of the study is to substantiate the parameters of the deep-loader of the mole-drainage gun. A diagram of a mole-drainage gun is given. The main working parts of the mole drainage tool are a deep loader, a knife, a rope and a drainer. Analytical dependences are obtained for determining the main parameters and traction resistance of the deep-loader of the mole-drainage gun. Theoretical studies have established that for high-quality loosening of the soil with minimal traction resistance, the height of the deep digger should be 90 cm, the width of its chisel is 7 cm, the angle of the chisel to the horizon is within 26-320, the length of the chisel is 11.5 cm, and the sharpening angle is 250. Installing a knife on a deep-loader increases the density of the dredge wall by 1.45-1.48 times, the depth of the dredge laying by 1.15 times, while the traction resistance of the mole-drainage gun decreases by 12.9%.

Abstract
Tillage is an important element of crop cultivation technology in the Krasnoyarsk Territory. The main processing solves such technological problems as deepening the arable layer due to the underlying layers or horizons, crumbling and loosening the soil, which ensures a change in the relative position of soil units with an increase in the number of pores, mixing and leveling the soil. Particular attention during the main processing should be paid to the quality of its implementation and the compliance of the soil after processing with agrotechnical requirements for the depth of processing, the uniformity of the depth of processing, the lumpiness of the surface, the rowness of arable land, and the looseness of the soil.

Published: September 2023

Abstract
The article presents the results of a multi-factorial experiment to justify the parameters of a rotating sprayer. Optimization of the parameters of the pneumatic disk atomizer shows that with the correct choice of the specific liquid flow rate (qi), disk radius (r) and the number of radial channels (η
r) at a constant air flow rate, it leads to obtaining the required median-mass droplet diameter. Therefore, when justifying the diameter of sprayed drops, it is necessary to consider a combination of the specific flow rate of the liquid and the radius of the disk. To obtain a monodisperse spray of drops with a median-mass diameter d= 80…120 µm, the disc radius should be in the aisles r=75.8…83.4 mm, the specific liquid flow rate qi= 0.61…0.96 l/min and the number of radial channels for pairs of disks in the aisles η
p = 4.59… 5.75 things.

Published: September 2023

Abstract
The effectiveness of the use of spray UAVs in precision agriculture largely depends both on the UAVs chosen for this purpose and their characteristics, and on the organization of the control of the UAV swarm, which requires an analysis of the UAV microprocessor performance in various modes of their use. It is possible to organize a general control of a swarm of UAVs, as well as individual control in offline mode. The article presents a methodology for analyzing the performance of spray UAVs in precision agriculture. A model example of the analysis of the microprocessor performance of a UAV swarm based on the specified system parameters is given. It is shown that the use of models of microprocessor performance of a swarm of UAVs in precision farming makes it possible to obtain the information necessary to make a decision on the development or purchase of UAVs of one type or another, the choice of fertilizer and pesticide spraying systems, the scaling and redundancy of UAVs and elements of the spraying system.

Abstract
An analysis of the drive characteristics of technological machines and mechanisms of agricultural production showed that their working bodies in 56.3% of cases have rotational motion, and in 43.7% they have translational motion. Special electromechanical and electromagnetic converters - an electric drive with a linear asynchronous motor - are very promising for driving the working bodies of technological equipment that perform translational and oscillatory motion, as well as rotational motion with a rotation speed of up to 500 min−1. A linear asynchronous electric drive makes it possible to implement technologically specified drive characteristics, integrate the power parts of an electric motor with a working body with the exception of mechanical converters, while reducing material and energy consumption, increasing operational reliability of process equipment as a whole. The choice of the optimal winding scheme and the design of the magnetic circuit of the inductor, the material of the secondary element increases the energy and traction performance of the linear induction motor. The study and modeling of electromagnetic processes and the optimization of geometric dimensions, winding data of the inductor and electrical parameters can be effectively carried out on a mathematical model of a linear induction motor by a numerical method, represented by a system of three matrix equations describing the states of the magnetic and electrical circuits of the machine, detailed to the level of tooth division and winding section.

Abstract
The article deals with the issues of improving the quality of the work of the cotton separation zone of the vertical spindle of the cotton spinning machine from the spindle, as well as the theoretical justification of the main parameters. The authors analyze the problems of technological processes in the separation zone of cotton production. For graphic construction and calculations, the COMPASS-GRAPH program was used. An analytical expression is found for a curved line in which the spindle is located in the center of the separator. Recommendations are given for the placement of the separator, based on the number of parts under the influence of the brushes of the cotton separator, the angle of rotation of the spindle around its axis in the process of interaction, and the operating time of the separator.

Abstract
The article discusses measures to prevent the shortage of vegetable and vegetable crops, increase their yield. In order to meet the demand of the population for these products if necessary to have export potential it is necessary to apply the achievements of modern science to the products grown. The use of new modern technologies will make a significant contribution to the development of the agricultural sector. When growing products in agriculture, traditional methods that require a lot of work should be abandoned. In this article there are seeds of muhima ahamita when growing crops. Germination and good crop development indicate the need to use modern technologies in seed processing. At the same time, it is necessary to take into account the cultivation of seeds and several factors affecting it. When treating seeds with ultraviolet radiation, it is necessary to study the effect of the exposure dose of light.
Features of calculating structures for frequent weak earthquakes
Authors: Belashov M , Benin A V , Hong Lin , Nazarova Sh Sh , Sabirova O B , Uzdin A M 
Published: September 2023

Abstract
The features of calculating structures for the action of weak earthquakes are analyzed. Earthquakes with a recurrence of 30 years and 50 years are considered. In the first case the structure is to operate normally without damage after the earthquake. In the second case damages are allowed that do not affect the possibility of the structure operation. Three issues are emphasized: setting elastic and damping characteristics of reinforced concrete, formalization of limit states and combinations of loads. The dependence of damping on the reinforcement coefficient is estimated. When evaluating limit states, in addition to calculations for crack resistance and strength, a human factor, i.e. the possibility of panic among people was considered. To avoid it, it is proposed to limit a storey-by-storey speed level in certain octave ranges. Proposals have been developed for estimating the coefficients of combination of various loads with the seismic one. As an example, coefficients of combinations of seismic and ice loads are estimated. It is shown, that for strong actions the combination coefficients for different regions turn out to be close, while for weak actions they may differ.

Published: September 2023

Abstract
Information technologies have entered all spheres of human life. Now they are an integral part of the modern world. These changes also affected the anti-crisis management system. The development of end-to-end technologies and the use of artificial intelligence allows for a better assessment and forecasting of risks. The methods used for forecasting the inflow to the site of a hydroelectric power station were analyzed in this paper. The data necessary to obtain a forecast were reviewed. An approach related to forecasting the inflow to the site of a hydroelectric power station using neural network forecasting methods is demonstrated. Using the python programming language, a neural network model was developed to predict the inflow to the hydroelectric station site. A recurrent network with a long short-term memory LSTM using 64 neurons was chosen as the network architecture. The data array for forecasting was obtained from the data of operational monitoring of the flood situation and archival data on flooding of the territory over the past 13 years, taken from the database of the Yenisei Basin Water Administration of the Federal Agency for Water Resources and the Central Siberian UGMS. The input parameters were selected empirically. When comparing real data on flow with the predicted ones, the error was 17%.

Published: September 2023

Abstract

Motivation
Imaging-based spatial transcriptomics (ST) technologies have achieved subcellular resolution, enabling detection of individual molecules in their native tissue context. Data associated with these technologies promise unprecedented opportunity toward understanding cellular and subcellular biology. However, in R/Bioconductor, there is a scarcity of existing computational infrastructure to represent such data, and particularly to summarize and transform it for existing widely adopted computational tools in single-cell transcriptomics analysis, including SingleCellExperiment and SpatialExperiment (SPE) classes. With the emergence of several commercial offerings of imaging-based ST, there is a pressing need to develop consistent data structure standards for these technologies at the individual molecule-level.

Results
To this end, we have developed MoleculeExperiment, an R/Bioconductor package, which (i) stores molecule and cell segmentation boundary information at the molecule-level, (ii) standardizes this molecule-level information across different imaging-based ST technologies, including 10× Genomics’ Xenium, and (iii) streamlines transition from a MoleculeExperiment object to a SpatialExperiment object. Overall, MoleculeExperiment is generally applicable as a data infrastructure class for consistent analysis of molecule-resolved spatial omics data.

Abstract
Perinatal nutrition modulates the hypothalamic neurocircuitries controlling GnRH release, thus programming pubertal maturation in female mammals. Objectives of experiments reported here were to test the hypotheses that prenatal nutrition during mid- to late gestation interacts with postnatal nutrition during the juvenile period in heifer offspring to alter expression of leptin receptor (LepR) variants (ObRa, ObRb, ObRc, ObRt), and lipoprotein transporter molecules (LRP1 and 2) in the choroid plexus, leptin transport across the blood–brain barrier, and hypothalamic–hypophyseal responsiveness to exogenous ovine leptin (oleptin) during fasting. Nutritional programming of heifers employed a 3 × 2 factorial design of maternal (high, H; low, L; and moderate, M) × postnatal (H and L) dietary treatments. Results (Expt. 1) demonstrated that prepubertal heifers born to L dams, regardless of postnatal diet, had reduced expression of the short isoform of ObRc compared to H and M dams, with sporadic effects of undernutrition (L or LL) on ObRb, ObRt, and LRP1. Intravenous administration of oleptin to a selected postpubertal group (HH, MH, LL) of ovariectomized, estradiol-implanted heifers fasted for 56 h (Expt. 2) did not create detectable increases in third ventricle cerebrospinal fluid but increased gonadotropin secretion in all nutritional groups tested. Previous work has shown that leptin enhances gonadotropin secretion during fasting via effects at both hypothalamic and anterior pituitary levels in cattle. Given the apparent lack of robust transfer of leptin across the blood–brain barrier in the current study, effects of leptin at the adenohypophyseal level may predominate in this experimental model.
Sustained induction of IP-10 by MRP8/14 via the IFNβ–IRF7 axis in macrophages exaggerates lung injury in endotoxemic mice

Abstract

Background
As a damage-associated molecular pattern, the myeloid-related protein 8/14 (MRP8/14) heterodimer mediates various inflammatory diseases, such as sepsis. However, how MRP8/14 promotes lung injury by regulating the inflammatory response during endotoxemia remains largely unknown. This study aims at illuminating the pathological functions of MRP8/14 in endotoxemia.

Methods
An endotoxemic model was prepared with wild-type and myeloid cell-specific Mrp8 deletion (Mrp8ΔMC) mice for evaluating plasma cytokine levels. Lung injury was evaluated by hematoxylin and eosin (H&E) staining, injury scoring and wet-to-dry weight (W/D) ratio. The dynamic profile of interferon γ (IFNγ)-inducible protein 10 (IP-10) mRNA expression induced by macrophage MRP8/14 was determined by quantitative real-time polymerase chain reaction (qPCR). Immunoblotting was used to evaluate the increase in IP-10 level induced by activation of the JAK–STAT signaling pathway. Luciferase reporter assay was performed to detect the involvement of IRF7 in Ip-10 gene transcription. In vivo air pouch experiments were performed to determine the biological function of IP-10 induced by MRP8/14.

Results
Experiments with Mrp8ΔMC mice showed that MRP8/14 promoted the production of cytokines, including IP-10, in the bronchoalveolar lavage fluid (BALF) and lung injury in endotoxic mice. The result of qPCR showed sustained expression of Ip-10 mRNA in macrophages after treatment with MRP8/14 for 12 h. Neutralization experiments showed that the MRP8/14-induced Ip-10 expression in RAW264.7 cells was mediated by extracellular IFNβ. Western blotting with phosphorylation-specific antibodies showed that the JAK1/TYK2-STAT1 signaling pathway was activated in MRP8/14-treated RAW264.7 cells, leading to the upregulation of Ip-10 gene expression. IRF7 was further identified as a downstream regulator of the JAK–STAT pathway that mediated Ip-10 gene expression in macrophages treated with MRP8/14. In vivo air pouch experiments confirmed that the IFNβ-JAK1/TYK2-STAT1-IRF7 pathway was required for chemokine (C-X-C motif) receptor 3 (CXCR3)+ T lymphocyte migration, which promoted lung injury in the context of endotoxemia.

Conclusions
In summary, our study demonstrates that MRP8/14 induces sustained production of IP-10 via the IFNβ-JAK1/TYK2-STAT1-IRF7 pathway to attract CXCR3+ T lymphocytes into lung tissues and ultimately results in lung injury by an excessive inflammatory response in the context of endotoxemia.

Abstract

Background
Coronavirus disease 2019 (COVID-19)–associated pulmonary aspergillosis (CAPA) is a frequent superinfection in critically ill patients with COVID-19 and is associated with increased mortality rates. The increasing proportion of severely immunocompromised patients with COVID-19 who require mechanical ventilation warrants research into the incidence and impact of CAPA during the vaccination era.

Methods
We performed a retrospective, monocentric, observational study. We collected data from adult patients with severe COVID-19 requiring mechanical ventilation who were admitted to the intensive care unit (ICU) of University Hospitals Leuven, a tertiary referral center, between 1 March 2020 and 14 November 2022. Probable or proven CAPA was diagnosed according to the 2020 European Confederation for Medical Mycology/International Society for Human and Animal Mycology (ECMM/ISHAM) criteria.

Results
We included 335 patients. Bronchoalveolar lavage sampling was performed in 300 (90%), and CAPA was diagnosed in 112 (33%). The incidence of CAPA was 62% (50 of 81 patients) in European Organisation for Research and Treatment of Cancer (EORTC)/Mycosis Study Group Education and Research Consortium (MSGERC) host factor–positive patients, compared with 24% (62 of 254) in host factor–negative patients. The incidence of CAPA was significantly higher in the vaccination era, increasing from 24% (57 of 241) in patients admitted to the ICU before October 2021 to 59% (55 of 94) in those admitted since then. Both EORTC/MSGERC host factors and ICU admission in the vaccination era were independently associated with CAPA development. CAPA remained an independent risk factor associated with mortality risk during the vaccination era.

Conclusions
The presence of EORTC/MSGERC host factors for invasive mold disease is associated with increased CAPA incidence and worse outcome parameters, and it is the main driver for the significantly higher incidence of CAPA in the vaccination era. Our findings warrant investigation of antifungal prophylaxis in critically ill patients with COVID-19.
Joan Robinson through the lenses of sixty years of book reviews
Authors: Marcuzzo Maria Cristina , Zacchia Giulia 
Published: September 2023

Abstract
In this paper, we discuss Joan Robinson’s views through the lenses of her 127 book reviews, an activity which she engaged in throughout her life. A complete list of them—so we hope—is presented with full reference to the original place of publication, in the form of tables arranged by decade. We follow her work in chronological order, taking each decade as the framework to analyse what she was working on at the time and show how her reviews were—at times loosely, at times closely—connected with her scientific and political concerns. In some cases, the reviews amounted to review essays, which she reprinted in her Collected Economic Papers, but even in the short reviews she managed to give full expression to her views on the topic or author, and thus they offer us additional insights into her mode of thought, examples of her crisp prose and forceful style of argument. Her reviews ranged over a great variety of topics, reflecting over 60 years of the development of economics, or at least those aspects and topics which she deemed relevant at the time, and so they come to form part of her intellectual legacy, as much as her published work.
