The tendency of anemia of inflammation in periodontal diseases
Authors: Han Ye , Luo Zhiqiang , Yue Zhao Guo , Miao Li Li , Xv Min , Chang Shu , Zhan Yalin , Hou Jianxia
Published: January 2023

Anemia of inflammation (AI) is associated with inflammatory diseases, and inflammation-induced iron metabolism disorder is the major pathogenic factor. Earlier studies have reported a tendency of AI in periodontitis patients, but the explicit relationship and possible pathological mechanisms remain unclear. Here, the analyses of both periodontitis patients and a mouse model of ligature-induced experimental periodontitis showed that periodontitis was associated with lower levels of hemoglobin and hematocrit with evidence of systemic inflammation (increased white blood cell levels) and evidence of iron restriction (low serum iron along with a high serum hepcidin and ferritin levels), in accordance with the current diagnosis criteria for AI. Moreover, periodontal therapy improved the anemia status and iron metabolism disorders. Furthermore, the increased level of hepcidin and significant correlation between hepcidin and key indicators of iron metabolism emphasized the pivotal role of hepcidin in the pathogenesis of periodontitis-related AI. Administration of the signal transducer and activator of transcription 3 (STAT3) inhibitors Stattic suggested that the IL-6–STAT3–hepcidin signaling pathway participated in this regulatory process. Together, these findings demonstrated that periodontitis should be considered an inflammatory disease that contributes to the development of AI; furthermore, IL-6–STAT3–hepcidin signaling pathway plays a key regulatory role in the pathogenesis of periodontitis-related AI. Our study will provide new insights into the systemic effects of periodontitis, while meaningfully expanding the spectrum of inflammatory diseases that contribute to AI.
Verification of Estimated Output Signal-to-Noise Ratios From a Phase Inversion Technique Using a Simulated Hearing Aid
Authors: Yun Donghyeon , Shen Yi , Lentz Jennifer J.
Published: January 2023

Purpose:

The signal-to-noise ratio (SNR) for speech presented in background noise may vary after being processed by digital hearing aids with nonlinear signal processing algorithms, such as wide dynamic range compression (WDRC). A phase inversion technique has been previously developed to assess the output SNR of hearing aids. However, systematic validations of this technique have not been conducted. This study aims to validate the phase inversion technique.

Method:

A simulated hearing aid with multichannel WDRC was implemented, from which the output SNRs, computed via shadow filtering, for connected speech in background noise were directly computed. The agreement between the shadow filter output SNRs and those estimated using the phase inversion technique for the same stimuli was utilized to validate the phase inversion technique. The background noise was 2- or 20-talker babble noise, and the speech stimuli were presented at SNRs of −10 to +10 dB at the input of the simulated hearing aid. The simulated hearing aid was configured to provide amplification for four representative audiograms, and the WDRC was set to be fast or slow acting. To investigate the effects of additive noise, independent of the presented noise stimulus, on the phase inversion estimated output SNR, the same simulated hearing aid was implemented with an additive Gaussian noise at its input (45 and 60 dB SPL).

Results:

Results showed that the phase inversion technique could either overestimate or underestimate output SNR, depending on the test condition; the estimation errors tended to coincide with temporal landmarks, such as natural pauses between consecutive sentences or fricatives; and increasing the simulated noise led to poorer estimates of output SNR.

Conclusions:

Results imply that the accuracy of the phase inversion technique is dependent on the test conditions. Thus, the phase inversion technique should be used with caution, and its validity should be evaluated further.
Extrapolation over temporal knowledge graph via hyperbolic embedding
Authors: Jia Yan , Lin Mengqi , Wang Ye , Li Jianming , Chen Kai , Siebert Joanna , Zhang Geordie Z. , Liao Qing
Published: January 2023

Predicting potential facts in the future, Temporal Knowledge Graph (TKG) extrapolation remains challenging because of the deep dependence between the temporal association and semantic patterns of facts. Intuitively, facts (events) that happened at different timestamps have different influences on future events, which can be attributed to a hierarchy among not only facts but also relevant entities. Therefore, it is crucial to pay more attention to important entities and events when forecasting the future. However, most existing methods focus on reasoning over temporally evolving facts or mining evolutional patterns from known facts, which may be affected by the diversity and variability of the evolution, and they might fail to attach importance to facts that matter. Hyperbolic geometry was proved to be effective in capturing hierarchical patterns among data, which is considered to be a solution for modelling hierarchical relations among facts. To this end, we propose ReTIN, a novel model integrating real‐time influence of historical facts for TKG reasoning based on hyperbolic geometry, which provides low‐dimensional embeddings to capture latent hierarchical structures and other rich semantic patterns of the existing TKG. Considering both real‐time and global features of TKG boosts the adaptation of ReTIN to the ever‐changing dynamics and inherent constraints. Extensive experiments on benchmarks demonstrate the superiority of ReTIN over various baselines. The ablation study further supports the value of exploiting temporal information.
Reconfigurable intelligent surface enhanced MISO‐OFDM anti‐jamming communications: Joint active and passive precoding design
Authors: Ren Zhangbo , Huang Kaizhi , Jiang Wenyu , Ma Keming , Yang Jie
Published: January 2023

The reconfigurable intelligent surface (RIS) fundamentally changes the existing anti‐jamming paradigm by reconstructing the wireless propagation environment. However, the existing RIS‐based anti‐jamming work mainly considers narrow‐band frequency‐flat fading channels. As an extension of existing work, the use of RIS to enhance the anti‐jamming capability of broadband orthogonal frequency division multiplexing (OFDM) system in frequency‐selective fading channels is first studied. In the multipath frequency‐selective fading channels, the anti‐jamming design needs to satisfy the channel gains of all signal paths with different delays. To this end, the authors propose a joint design scheme of active precoding at the transmitter and passive precoding at the RIS to attenuate the jamming signal and enhance the legitimate signal, and formulate the joint design objective to maximize the average rate of all subcarriers. An alternating optimization algorithm is developed to address this non‐convex problem due to the complex coupling of active and passive precoding. In detail, the active and passive precoding are solved by the Cauchy–Schwarz inequality and power water‐filling method and the alternating direction method of multipliers method assisted by multidimensional complex quadratic transform, respectively. Simulation results demonstrate that the proposed method can significantly improve the anti‐jamming communication performance of the OFDM system compared with the scheme without RIS. In addition, the impact of the number of RIS elements and deployment location on system performance is revealed.

3D layout estimation of general rooms based on ordinal semantic segmentation
Authors: Yao Hui , Miao Jun , Zhang Guoxiang , Chu Jun
Published: January 2023

Room layout estimation aims to predict the location and range of layout planes of interior spaces. Previous works treat each layout plane as an independent individual without considering the ordinal relation between walls, resulting the loss of the wall planes and the lack of integrity. This paper proposes a novel two‐branch neural networks model to estimate 3D layouts of cuboid and non‐cuboid room types. The model embeds the ordinal relation between layout planes into the layout segmentation branch through an proposed ordinal classification loss function, and outputs both pixel‐level layout segmentation maps and layout plane parameter maps. Then, the instance‐level plane parameters of each layout plane are determined by using an instance‐aware pooling layer. Finally, the sharpness of layout edges of the 2D layout semantic segmentation map is optimized by using an improved depth map intersection algorithm. Furthermore, we annotate a large‐scale 3D room layout estimation dataset, InteriorNet‐Layout, to obtain a steady model. Experiments on synthesized real‐world datasets show that the proposed method achieves faster calculation while maintaining high accuracy.

Temperature‐dependent adaptive conductivity coating for surface charge release and electric field control under electro‐thermal coupling field
Authors: Xue Jianyi , Zhang Zhu , Li Binbin , Zhao Yushun , Ding Lijian
Published: January 2023

Surface charge accumulation is the potential criminal for surface insulation failure on spacers under direct current (DC) voltages. The existence of thermal gradient posing the difficulty of surface charge regulation. This study proposes a temperature‐dependent adaptive conductivity coating technique for surppressing surface charge accumulation under electro‐thermal coupling field. A two‐dimensional axis‐symmetrical simulation model regrading surface charge computation is established. The effects of thermal gradients and coating conductivity on surface charge and electric field distribution are investigated. The results show that the thermal gradient increases the bulk conductive current, therefore aggravating surface charge accumulation. The effects of the coating condcutivity on surface charge and electric field contains three stages. The lower coating conductivity leads to aggravated homo‐polarity charge accumulation. By increasing the coating conductivity, the surface charge and electric field are significantly suppressed at the obtained optimal conductivity, where the bulk and surface conductive current reach a balance stage. Continuously increasing the coating conductivity results in aggravated hetero‐polarity charges. Besides, the increase of thermal gradient to an appropriate extent contributes to the further suppression of surface charge on coated spacers. It is hoped that this study could provide some references for designing highly reliable DC GIL under electro‐thermal coupling field.

Published: January 2023

A compact, ultra‐thin electromagnetic bandgap (EBG) backed antenna is presented for the 24 GHz ISM band for WBAN applications. The proposed antenna has Koch fractal geometry‐based bow‐tie slots, designed with an overall dimension of 0.91 × 0.84 × 0.01 and backed by a 5 × 5 element 0.01 thick EBG structure; it is fabricated on a flexible Rogers 5880 substrate (thickness = 0.127 mm and dielectric constant  = 2.2, tanδ = 0.0009). In comparison to the previously published K band prototype antennas, our presented fractal antenna has a more compact and ultra‐thin form factor. The low profile, via‐less EBG unit cell structure with dimensions of 0.254 × 0.254, possesses both Artificial Magnetic Conductor (AMC) and EBG characteristics. It is straightforward to fabricate at a millimeter‐scale. The performance parameters of the design are investigated in terms of on‐body reflection coefficient and free‐space radiation patterns with and without structural bending. The EBG structure enhances the antenna's front‐lobe gain by 2.3 dB, decreases back‐lobe radiation by 12.6 dB and decreases the specific absorption rate (SAR [1 g]) from >50.9 W/kg to <6.14 W/kg, significantly reducing the potential harm to the human body. Experimental investigations revealed high insensitivity of the proposed antenna to body proximity, and the performance is preserved with structural deformation.
Analytical evaluation of single‐input dual‐output based integrated luo‐buck converter for BLDC motor
Authors: Chandran Praveenkumar , Mylsamy Kaliamoorthy , Umapathy Prabha S
Published: January 2023

A single‐input dual‐output (SIDO) converter is proposed in the research article for usage in electric vehicle (EV) applications. The main objectives of the proposed integrated Luo‐Buck converter (ILBC) based BLDC drive system are to develop a multi‐purpose converter with low complexity and high efficiency, as well as to reach the rated speed of BLDC‐based vehicles. The multi‐output converter is generally employed in EV applications because of the primary load and extra auxiliary loads like sensors, power steering, headlights, and so on. The proposed system achieves both of the aforementioned objectives. As there are just two switches, fewer gate driver circuits are required, which indirectly lowers the complexity of the circuit. Since they do not require large duty cycles, ILBC switches experience less voltage and current stress. The switches can only be used at duty cycles of 60% and 30%. For design purposes, output filter capacitor sizes are likewise maintained to a minimum. The 1.2 kW BLDC is powered by the ILBC, which has a maximum efficiency of 96.16%, in order to validate the suggested system using the hardware prototype model. The rated speed can be attained with the least amount of timing. Additionally, the suggested approach lessens voltage and torque ripple.
Generation of a synthetic aperture radar deception jamming signal based on a deep echo inversion network
Authors: Xiao Yihan , Dai Liang , Yu Xiangzhen , Zhou Yinghui , Zhao Zhongkai
Published: January 2023

Existing methods for generating synthetic aperture radar (SAR) deception jamming signals have slow speed, low imaging quality, and insufficient intelligence in complex electromagnetic environments. This paper proposes a deep learning‐based SAR deception jamming signal generation method based on deep echo inversion Unet (DEIUnet). This method has high speed and provides high‐image quality of the interference signal. A Swin Next (SN) block is proposed to combine local and non‐local information in the image and echo data. The Unet structure consists of SN blocks, and a residual connection is used as the jump connection to fuse the multi‐scale feature information from the echo and image data. PixelShuffle is utilised for up‐sampling to generate high‐quality echo data. The experimental results on MSTAR and Sentinel‐1 data sets verify the effectiveness and superiority of DEIUnet for echo inversion. The imaging results of the SAR deception jamming signal generated by DEIUnet on an MSTAR scene confirm the effectiveness of the proposed method.
Forecast of area‐scale behaviours of behind‐the‐metre solar power and load based on smart‐metering net demand data
Authors: Miyasawa Ayumu , Akira Shogo , Fujimoto Yu , Hayashi Yasuhiro
Published: January 2023

Local energy self‐sufficiency, in which the supply and demand of electricity are controlled such that the generated power from distributed energy resources (DERs) is consumed locally based on a power supply‐and‐demand forecast, mitigates the burden on the power system and contributes to the efficient use of DERs in smart cities. However, widely available smart metres cannot measure behind‐the‐metre pure demand and generation from prosumers. Pure demand and generation forecasts without additional metering contribute to advanced supply‐and‐demand control in smart cities, including demand response. This study proposes a method of forecasting spatio‐temporal behaviours of behind‐the‐metre pure demand and generation by focussing on the information of net demand distribution observable from the smart metres; the proposed method initially predicts the spatio‐temporal net demand distribution with a combined forecaster based on the persistence and non‐parametric regression models, and then separately estimates the behind‐the‐metre pure demand and generation by using demand forecast result of neighbouring pure‐consumers extracted by considering the area‐scale behaviours of the smart metering data. The simulation results demonstrate that the proposed method provides accuracy comparable to forecasts conducted by directly measuring pure demand and generation, without requiring the installation of additional metres.
An only metal, compact, and circular polarizer designed with helical array rods
Authors: Hosseini Seyed Jalil
Published: January 2023

This paper presents a simple method to realize a circular polarizer by inserting rods arranged helically in a cylindrical waveguide. In the proposed polarizer, the rods are installed to excite the electric fields perpendicular to the input field. In addition, the rod locations create a 90° phase difference between two perpendicular axes to convert the polarization from linear to circular. In the proposed structure, the axial ratio is smaller than 0.4 dB, and the phase difference is approximately 90° at a frequency of 10 GHz. In addition, the reflection coefficients are better than −14 dB for both the and polarizations at the same frequency. Additionally, this structure is very compact compared to similar systems. Furthermore, this is made only of metal. Therefore, there is no dielectric loss. The validation results are in good agreement with the simulation.

Published: January 2023

Aims. The formation process of multiple populations in globular clusters is still up for debate. These populations are characterized by different light-element abundances. Kinematic differences between the populations are particularly interesting in this respect because they allow us to distinguish between single-epoch formation scenarios and multi-epoch formation scenarios. We derive rotation and dispersion profiles for 25 globular clusters and aimed to find kinematic differences between multiple populations to constrain their formation process.

Methods. We split red-giant-branch (RGB) stars in each cluster into three populations (P1, P2, and P3) for the type-II clusters and two populations (P1 and P2) otherwise using Hubble photometry. We derived the global rotation and dispersion profiles for each cluster by using all stars with radial velocity measurements obtained from MUSE spectroscopy. We also derived these profiles for the individual populations of each cluster. Based on the rotation and dispersion profiles, we calculated the rotation strength in terms of ordered-over-random motion, (v/σ)HL, evaluated at the half-light radius of the cluster. We then consistently analyzed all clusters for differences in the rotation strength of their populations.

Results. We detect rotation in all but four clusters. For NGC 104, NGC 1851, NGC 2808, NGC 5286, NGC 5904, NGC 6093, NGC 6388, NGC 6541, NGC 7078, and NGC 7089, we also detect rotation for P1 and/or P2 stars. For NGC 2808, NGC 6093, and NGC 7078 we find differences in (v/σ)HL between P1 and P2 that are larger than 1σ. Whereas we find that P2 rotates faster than P1 for NGC 6093 and NGC 7078, the opposite is true for NGC 2808. However, even for these three clusters the differences are still of low significance. We find that the rotation strength of a cluster generally scales with its median relaxation time. For P1 and P2 the corresponding relation is very weak at best. We observe no correlation between the difference in rotation strength between P1 and P2 and the cluster relaxation time. The stellar radial velocities derived from MUSE data that this analysis is based on are made publicly available.
Complexity parameters of solar-wind magnetic fluctuations at 1 AU during SC23 and SC24
Authors: Acosta-Tripailao B. , Pastén Denisse , Moya Pablo S.
Published: January 2023

Context. The solar wind develops a highly turbulent character during its expansion, where plasma and electromagnetic fluctuations coexist. Considering the presence of turbulence in the plasma as a complex system, the turbulence in the solar wind in general has been measured and studied using different techniques from a systems science point of view. These techniques provide the opportunity to obtain preliminary information even before much of the physics can be assimilated and integrated.

Aims. We describe this plasma as a complex system in order to understand solar wind dynamics from a new perspective. Several missions provide a wide range of data concerning critical astrophysical phenomena. This poses a challenge to implement new effective methods to complement the characterization of the constantly new, and sometimes highly reduced information, especially when dealing with observational data with intermittent gaps.

Methods. We work with magnetic fluctuation time series data obtained from the Wind mission at 1 AU in order to characterize the fast and slow solar wind behavior during solar cycles 23 (SC23) and 24 (SC24). We applied the horizontal visibility graph (HVG) method to obtain the evolution of measurements of Kullback-Leibler divergence (KLD), D, and the characteristic exponent, γ, over time. Both are complexity parameters extracted from the degree distributions of the networks.

Results. By contrasting our complexity parameters, γ and D, with solar activity characterized by the number of sunspots and solar wind speed, we obtain significant intercorrelations among them during both cycles and ascending, descending, minimum, and maximum phases. According to γ values, the magnetic fluctuations of the solar wind are a correlated stochastic time series at 1 AU. Also, the divergence D recognizes SC23 as the most dissipative and identifies the slow wind as more variable than the fast wind, with a better anti-correlation in the minima phases. This study reveals that in terms of solar phases γmin > γdes > γasc > γmax, and Dmin < Ddes < Dasc < Dmax. We show that the HVG technique leads to results that are consistent with the complex nature of solar wind turbulence.

Prospects for the renovation and modernization of urban development in the regions
Authors: Kolobova Svetlana
Published: January 2023

The article examines the prerequisites for the organization and implementation of renovation and modernization of the urban built environment in the regions of Russia. Since the largest number of multi- apartment panel residential buildings were built in the Moscow, pilot projects for the reconstruction and renovation of residential buildings were launched here. The programs were initially aimed at the reconstruction of five-storey dilapidated panel and block residential buildings. However, over time, 9-12-16–storey panel houses appear on the queue, which expire the period of physical and moral wear and tear. The technical condition of multi- apartment panel houses in various cities of the country is characterized by a decrease in the bearing capacity and operational characteristics of building structures and in the coming decades may lead not only to a decrease in consumer characteristics of housing, but also to the emergency condition of houses. In all regions of the country, major renovation programs of apartment buildings are currently being implemented. However, carrying out only planned work on the overhaul of residential buildings cannot solve the problem of restoring load-bearing structures and internal communications completely and, moreover, eliminate the moral deterioration of buildings that has occurred. Therefore, there is a need and expediency of an integrated approach to the renewal of the built-up urban environment, renovation and further modernization of the territory, the creation of a modern architectural appearance of the city with developed infrastructure and convenient transport interchanges. Due to the transition to digital technologies in the construction industry, there is a need to modernize the built environment. In the process of carrying out measures to modernize urban development with the introduction of digital technologies, the investment attractiveness of the territory increases. And this factor is most important for the long-term development of the territory.

In the fourth part conclusions are drawn and summed up. The main results of the work are the algorithmic implementation of noise removal from halftone images grayscale images using a software tool developed as part of these studies.
Globalism, controlled chaos and values

Published: January 2023

Consideration of the program of globalism and the concept of controlled chaoswas carried out on the basis of a study of the works of A. Toffler and S. Mann. This article analyzes the terminological basis of the proposed concepts. It is proved that the development of information communications testifies to the evolutionarity of processes on the world stage, which cannot be considered a feature of a revolutionary change in the type of civilization. The criticism of the Western attitude about the positioning of the newest society as purely informational, practically unrelated to industrial achievements, is given. It is shown that in reality the information boom is fully provided by the material production of the "second wave", within the framework of the development of which the possibility of solving various pressing problems, including the problem of energy resources, is visible. Special attention in the article is devoted to the criticism of the concept of «controlled chaos» from the perspective of synergetic methodology, the real threats associated with misunderstanding of the behaviour of nonlinear dynamical systems in the bifurcation mode are outlined. The implementation of the globalism program uses many techniques aimed at standardizing values. In this regard, the Kantian narrative of absolute value.

Published: January 2023

Blood groups, due to their irremovability and independence from gender, age, feeding conditions and maintenance, are widely used in animal breeding. The purpose of this study was to identify genetic markers of economically valuable traits of cattle of Kalmyk breed. Analysis of polymorphism of blood groups of Kalmyk cattle during the study period showed that there are antigens in the allelofond with a high concentration and frequency of occurrence: А1, A2, D', W, V, and Z, while G2I', C2 remain with low one. Analysis of the genetic status of different breeds revealed that there are obvious differences in frequencies. Antigens A1,A2,E’3,Z can serve as genetic markers of Kalmyk cattle purebred. The highest index of genetic distance was 0.1931 between the Kalmyk breed of the Republic of Kazakhstan and the Kazakh white-headed breed. The smallest genetic distance was found between the Simmental breed and the Kalmyk AO and is equal to 0.1166. The identification of the most effective method of selection, taking into account the index of genetic similarity, revealed the smallest number of parent pairs in the low (0.0-0.30) and high (0.61-0.90) indices of antigenic similarity and amounted to: “Agrofirma Aduchi” LLC – 24 pairs (16%) and 48 pairs (32%), “Sarpa” AO – 17 pairs (11%) and 21 pair (14%), A. A. Chapchayev AO PZ – 15 pairs (10%) and 9 pairs (6%), “Agribusiness” LLC – 8 pairs (5%) and 7 pairs (5%), respectively. When selecting parent pairs with an antigenic similarity index of 0.31-0.60, it allows to get bullheads with the highest live weight. Antigens marking the index value of 0,31-0,60, А1, А2, G2, E’3, C2, Z are considered genetic markers of the reproductive ability of Kalmyk breed cattle.

Research on the study of parasitocenoses in endometritis and mastitis in cows, as well as gastrointestinal and respiratory diseases of newborn calves, were carried out in 12 farms in the Moscow region with a total number of 4,445 cows and 12,254 cattle. It was found that parasitocenosis in cattle in the farms of Moscow region are vulnerable to factor of infections composed of S. agalactiae, S. dysgalactiae, S. uberis, S. pyogenes, S. pneumoniae, S. faecalis, S. aureus, S. albus, S. saprophyticus, S. epidermidis, S. intermedius, S. enterica (S. enteritidis, S. typhimurium, S. dublin), E. coli (O1, O2, O4, O8, O9, O18, O22, O26, O33, O78, O101, O111, O126, O137), P. aeruginosa, P. multocida, K. pneumoniae, K. oxytoca, P. vulgaris, P. mirabilis, B. subtilis, B. cereus, C. freundii, L. plantarum, L. rhamnosus, L. acidophilus, L. xylosus, L. lactis and C. albicans. This research found that mastitis and endometritis in cows, as well as gastrointestinal and respiratory diseases in newborn calves, are caused by almost similar associations of microorganisms (parasitocenoses) that circulate in the farm (intra-farm infection). The results of the experiment indicate that the association of conditionally pathogenic microorganisms that circulate among cattle of farms in the Moscow region are parasitocenoses, and are independently regulated under the influence of macroorganism and environmental factors; it is a complex, multicomponent, strictly balanced ecosystem, each of which is an important link in the etiological factor of cattle infections.

Until recently, it was believed that the effects of probiotics are limited to a certain range of specific effects, but more and more studies indicate that their action on the host organism is more complex and systemic. Such effects interference of probiotics in the regulation of various pathways in the host organism. Systemic effect does not mean the sum of many minor impacts but precisely targeted impact on the most sensitive points or metabolic pathways. That allows to achieve a more significant effect in small doses through a cascade of reactions. In this case, probiotics can act both through the effect on other symbiont bacteria and directly on the host. One of the agents of such interactions can be oligopeptides of nonribosomal origin.

Aquaculture is a fast-growing sector in Russia. To grow fish to a greater extent than for other agricultural objects, it is necessary to preserve and maintain natural habitat conditions. Minor changes in the aquatic environment, such as changes in pH, temperature fluctuations, and the presence of organic pollutants can lead to a decrease in the number of fish. Use of antibiotic drugs for the prevention and treatment of diseases in fish farming can lead to a change in the microbiocenosis of fish and the hydroecosystem, the appearance of antibiotic-resistant strains of pathogenic microorganisms and a change in the immunophysiological status of the fish organism. To date, a promising and effective therapeutic and prophylactic agent in fish farming is the use of probiotics, which have pronounced antimicrobial activity against pathogenic and conditionally pathogenic microorganisms, immunocorrecting and anti-inflammatory effect. As a result of our research, we have established the effectiveness of the use of preparations Subalin containing Bacillus subtilis and Zoonorm containing live bacteria Bifidobacterium bifidum in the cultivation of carp. A positive effect on the increase in body weight of fish was revealed, the level of contamination of parenchymal organs of fish with bacterial flora decreased, specific and nonspecific resistance increased.

This work is devoted to the use of probiotics in growing broiler chickens and the problem of obtaining poultry products of high biological properties, produced with the minimum use of antibiotic and chemical substances that can harm both the consumer and the environment. World practice shows the gradual rejection of feed antibiotics. The ban on the use of feed antibiotics does not lose its relevance in Russia. This is due to both the growth in demand for livestock products obtained without the use of antibiotics, and the tightening of veterinary and sanitary rules. Obtaining such products includes a set of measures, which includes the use of natural feed additives that optimize the functioning of the digestive tract and allow reducing or avoiding the use of antimicrobial agents. The role of intestinal microflora for maintaining the normal functioning of the intestine, performing a number of important physiological functions is presented, it is shown what parameters when growing broiler chickens affect the composition of the microflora of the digestive system, and what contributes to the spread of intestinal infections in poultry farms. The characteristics of the probiotic are given and the mechanism of action and biological properties of the additive are considered. Issues related to the feasibility of prophylactic and therapeutic use of probiotics in poultry farming, intended to restore and maintain beneficial microflora of the gastrointestinal tract, as well as to control pathogenic microflora, are considered.
