Published: May 2024

In the evolving landscape of crisis leadership and emergency management, artificial intelligence (AI) emerges as a potentially transformative force with far-reaching implications. Utilizing the POP-DOC Loop, a comprehensive framework for crisis leadership analysis and decision-making, this paper delves into the diverse roles that AI is poised to play in shaping the future of crisis planning and response. The POP-DOC Loop serves as a structured methodology, encompassing key elements such as information gathering, contextual analysis informed by social determinants, enhanced predictive modeling, guided decision-making, strategic action implementation, and appropriate communication. Rather than offer definitive predictions, this review aims to catalyze exploration and discussion, equipping researchers and practitioners to anticipate future contingencies. The paper concludes by examining the limitations and challenges posed by AI within this specialized context.

Authors: Pettitt-Schieber Brian , Lesko Robert P. , Wang Fei , Shah Jinesh , Ricci Joseph A.
Published: May 2024

Objective: Distal radius fractures (DRFs) are one of the most common orthopedic injuries, with most managed in the nonoperative ambulatory setting. The objectives of this study are to examine National Health Center Statistics (NHCS) data for DRF treated in the nonoperative ambulatory setting to identify opioid and nonopioid analgesic prescribing patterns and to determine demographic risk factors for prescription of these medications.
Design, setting, patients, and measures: This study is a retrospective analysis of data collected by the NHCS from 2007 to 2016. Utilizing International Classification of Diseases codes, all visits to emergency departments and doctors’ offices for DRFs were identified. Variables of interest included demographic data, expected payment source, and prescription of opioid or nonopioid analgesics.
Results: During the study timeframe, 15,572,531 total visits for DRFs were recorded. DRF visits requiring opioid and nonopioid analgesic prescriptions increased over time. Patients aged 45-64 years were significantly more likely to receive an opioid prescription than any other age group (p < 0.05). Opioid prescription was positively correlated with the use of workers’ compensation and negatively correlated with patients receiving services under charity care (p < 0.05).
Conclusions: Prescriptions of both opioid and nonopioid analgesic medications for DRF have been steadily increasing over time in the nonoperative ambulatory setting, with middle-aged adults most likely to receive an opioid prescription. Opioid prescription rates differ significantly between patients utilizing workers’ compensation and patients receiving services under charity care, suggesting that socioeconomic factors play a role in prescribing patterns.

Authors: Castro Estela Carielli de
Published: May 2024

Este artigo visa analisar como a cor é utilizada para a construção dos sentidos na HQ O despertar de Cthulhu. Para embasar a discussão, partimos da multimodalidade (KRESS; VAN LEEUWEN, 2006; KRESS, 2010). O corpus se constitui de três histórias da HQ. Para a análise, foram escolhidas as categorias de modalidade, da metafunção interativa, e saliência, da metafunção composicional. Com base nessas categorias, observarmos que a cor verde, nas três histórias, constrói uma representação do sobrenatural/maligno, o que constrói um senso de unidade, além das cores assumirem a função de interagir com o leitor e conduzirem a narrativa.

In 2017-2023 on the territory of Moscow region studied three types of plantings of Pennsylvania ash that survived the invasion of Agrilus planipennis in 2005-2012. All the trees damaged by the larvae A. planipennis. Most of the trees died (75%), the surviving trees remain the chronic ground of pests for twenty years. The surviving trees (25%) cropped, the assessment of their condition in 2017-2018 met the criterion of "weakened", in 2018-2023 – "severely weakened". The improvement in the condition of the trees in 2014-2018 replaced by a deterioration in 2021. Among the three types of plantings, the satisfactory condition of trees found in squares and multi–row plantings along streets, poor - in single-row plantings along streets. In the next decade most of the plantings along the streets degrade, other types of plantings remain. At the squares and parks of the center of the Moscow megalopolis, the trees partially restores the crown and partially overgrowing of old larval galleries on trunks. Damage by A. planipennis on multi-row plantings along highways provoked an outbreak of Leperesinus varius in 2006-2008. The synergy of A. planipennis and L. varius caused the rapid death of the Pennsylvania ash tree in the Moscow region. Trees trimmed to 1/3 of the crown and the "weakened" category live for at least 8 years, the "severely weakened" category – for at least 5 years. Removing from 1/3 to 2/3 of the crown is advisable only for trees of the "weakened" category. Removing more than 2/3 of the crown and topping with the removal of the top and skeletal branches leads to death of the tree. Keywords: GREEN ASH, EMERALD ASH BORER, HEALTH OF URBAN PLANTINGS

Enhancing Quality of Service and Energy Efficiency in Wireless Sensor Networks through TDMA-Based Topology and Cross-Layer Approaches
Authors: Iqbal Muhammad Junaid , Afzal Shan , Raza Usman Ahmed
Published: May 2024

It is necessary to continuously monitor the environment with the sensors in delay-sensitive wireless sensor network applications. The continuous monitoring operation results in higher energy consumption by the sensor nodes; wireless sensor networks are also subject to numerous difficulties, including latency, packet loss, and throughput. These are the most important constraints in wireless sensor networks (WSNs) and need to improve for better quality communication. In this research, quality of service is related to numerous systems that have very sensitive parameters such as end-to-end delay, packet loss, throughput, energy consumption, latency, and average delay. Therefore, it is necessary for the sensors to transmit reliable data within a reasonable timeframe. To find out better communication results, we have used the TDMA (Time Division Multiple Access) approaches in our paper to improve packet delivery ratio (PDR), latency, and throughput. The NS2 simulator is used to test communication between nodes. Latency, the packet delivery ratio (PDR) of transferring data packets, and throughput are measured. The TDMA approach is used in our proposed topology, and we can see a specific area where nodes are connected to communicate with one another. Each node is communicating with the other node using two different paths. Each node's bandwidth, latency, and PDR will be different. Hence, in one path, a TDMA approach is implemented, which results in improved node performance in terms of latency, packet delivery ratio, and bandwidth.
“Foi tudo difícil viu, difícil e perigoso”: memória, trauma e esquecimento de um preso político da Operação Mesopotâmia (1971), em Porto Franco-MA
Authors: Barros Silva Wellisson Rafael , Veras Rogério
Published: May 2024

A Operação Mesopotâmia foi uma ação do Exército brasileiro realizada nas fronteiras entre os estados do Pará, Maranhão e Tocantins, na primeira quinzena do mês de agosto de 1971. A Operação tinha como objetivo levantar informações e reprimir movimentos sociais e partidos políticos oposicionistas da Ditadura civil-militar que se organizaram na região. Objetivamos compreender como ocorreram os processos de esquecimento e silenciamento por quem foi vitimado por essa ação. Servindo-nos dos recursos da História Oral, trazemos para análise uma entrevista com o camponês Messias Chaves, um dos presos políticos da Operação, dialogando teoricamente com os estudos sobre memórias traumáticas e do testemunho. Compreendemos, a partir deste caso, que o silenciamento sobre a Operação, bem como o seu rompimento, estão relacionados aos distintos contextos políticos após a redemocratização.

Technological methods have been developed to acquire an active component with a high SiO2 content, which serves as a matrix foundation for synthetic adsorbents made from chrysotile asbestos production waste composite materials. Comparative analyses were conducted between the obtained adsorbent and a zeolite adsorbent of the NaX model. The physico-chemical analyses unveiled that the synthetic adsorbent obtained is not inferior in any aspect, and in certain instances, even outperforms in the demetallization process of heavy petroleum raw materials. The demetallization process exhibits an optimal temperature range of 380-410 °C, with a contact time of 60 minutes and a pressure range of 8-10 atm. Concurrently, the concentration of vanadium in heavy crude oil decreases significantly from 540 to 28 micrograms per kilogram, while nickel content diminishes from 50 to 26 micrograms per kilogram. Moreover, iron content experiences a reduction from 50 to 12 micrograms per kilogram, and sulfur content decreases from 3.50 % to 2.39 %.
Calibration of Low-Cost Particulate Matter Sensors PurpleAir: Model Development for Air Quality under High Relative Humidity Conditions
Authors: Mathieu-Campbell Martine E. , Guo Chuqi , Grieshop Andrew P. , Richmond-Bryant Jennifer
Published: May 2024

Abstract. The primary source of measurement error from the widely-used particulate matter (PM) PurpleAir sensors is ambient relative humidity (RH). Recently, the U.S. EPA developed a national correction model for PM2.5 concentrations measured by PurpleAir sensors (Barkjohn model). However, their study included few sites in the Southeastern U.S., the most humid region of the country. To provide high-quality spatial and temporal data and inform community exposure risks in this area, our study developed and evaluated PurpleAir correction models for use in the warm-humid climate zones of the U.S. We used hourly PurpleAir data and hourly reference grade PM2.5 data from the EPA Air Quality System database from January 2021 to August 2023. Compared with the Barkjohn model, we found improved performance metrics with error metrics decreasing by 16–23 % when applying a multi linear regression (MLR) model with RH and temperature as predictive variables. We also tested a novel semi-supervised clustering (SSC) method and found that a nonlinear effect between PM2.5 and RH emerges around a RH of 50 % with slightly greater accuracy. Therefore, our results suggested that a clustering approach might be more accurate in high humidity conditions to capture the non-linearity associated with PM particle hygroscopic growth.
GraphFlood 1.0: an efficient algorithm to approximate 2D hydrodynamics for Landscape Evolution Models
Authors: Gailleton Boris , Steer Philippe , Davy Philippe , Schwanghart Wolfgang , Bernard Thomas Guillaume Adrien
Published: May 2024

Abstract. Computing hydrological fluxes at the Earth's surface is crucial for landscape evolution models, topographic analysis, and geographic information systems. However, existing formalisms, like single or multiple flow algorithms, often rely on ad-hoc rules based on local topographic slope and drainage area, neglecting the physics of water flow. While more physics-oriented solutions offer accuracy (e.g. shallow water equations), their computational costs limit their use in term of spatial and temporal scales. In this conrtibution, we introduce GraphFlood, a novel and efficient iterative method for computing river depth and water discharge in 2D on a digital elevation model (DEM). Leveraging the Directed Acyclic Graph (DAG) structure of surface water flow, GraphFlood iteratively solves the 2D shallow water equations. This algorithm aims to find the correct hydraulic surface by balancing discharge input and output over the topography. At each iteration, we employ fast DAG algorithms to calculate flow accumulation on the hydraulic surface, approximating discharge input. Discharge output is then computed using the Manning flow resistance equation, similar to the River.lab model. Iteratively, the divergence of discharges increments flow depth until reaching a stationary state. This algorithm can also solve for flood wave propagation by approximating the input discharge function of the immediate upstream neighbours. We validate water depths obtained with the stationary solution against analytical solutions for rectangular channels and the River.lab and Caesar Lisflood models for natural DEMs. GraphFlood demonstrates significant computational advantages over previous hydrodynamic models, with approximately a 10-fold speed-up compared to the River.lab model. Additionally, its computational time scales slightly more than linearly with the number of cells, making it suitable for large DEMs exceeding 106–108 cells. We demonstrate the versatility of GraphFlood in integrating realistic hydrology into various topographic and morphometric analyses, including channel width measurement, inundation pattern delineation, floodplain delineation, and the classification of hillslope, colluvial, and fluvial domains. Furthermore, we discuss its integration potential in landscape evolution models, highlighting its simplicity of implementation and computational efficiency.
Technical note: Evolution of convective boundary layer height estimated by Ka-band continuous millimeter wave radar at Wuhan in central China

Published: May 2024

Abstract. Using the vertical velocity (VV) observed by a Ka-band millimeter wave cloud radar (MMCR) at Wuhan, we investigate the evolution of convective boundary layer height (CBLH) based on a specified threshold of VV variance. Compared with the CBLH retrieved from the lidar range corrected signal (RCS), the MMCR-derived CBLH exhibits lower values for a few hours post-sunrise and pre-sunset, but outside these two periods, they are generally in good agreement. Relative to the lidar RCS that is susceptible to the historical aerosol mixing processes, the CBLH estimated from the MMCR VV variance shows a rapid response to thick clouds and a less contamination by aerosol residual layer and long-distance transport of sand and dust, thus the MMCR VV observation can capture the CBLH evolution very well. The MMCR observation in 2020 depicts the seasonal and monthly variations in the CBLH. The seasonal mean CBLH reaches the peak heights of 1.29 km in summer, 1.14 km in spring, and 0.6 km in autumn and winter, with occurrence time between 13:30 and 15:00 LT. The maximum (mean) value of mean (daily maximum) CBLH rises steadily from 0.66 (0.87) km in January to 1.47 (1.76) km July, followed by a gradual decline to 0.42 (0.5) km in December. Statistical standard deviations are monthly-dependent, indicating the significant influence of weather conditions on the CBLH. This study improves our understanding of the Ka-band MMCR’s capability to monitor the CBLH, emphasizing its utility in tracking the dynamical processes in the boundary layer.

Published: May 2024

Abstract. In the present study, a new configuration for a micro-feed tool rest driven by piezoelectric ceramics with a rigid–flexible phase is designed. The flexible driving part of the micro-feed tool rest is optimized using the topology optimization method, which not only improves the driving stiffness, resolution and structural stability but also increases the maximum displacement. The structural stiffness achieved in finite element simulation analysis is 16.28 N µm−1, and the first natural frequency reaches 2521 Hz. A prototype of a piezoelectrically driven micro-feed tool holder and a testing platform are constructed, and the structural stiffness of the prototype is determined to be 15.53 N µm−1 via analysis and testing, resulting in an error of 4.8 % compared with the finite element simulation results. The first-order natural frequency is 2636 Hz given a resolution of 12 nm and a maximum output displacement of 12.983 µm. Compared with the double-parallel flexible hinge, the maximum stroke of the micro-feed tool holder increases by about 5.4 µm and the resolution is improved by about 50 %. The new micro-feed tool holder developed in this paper features a cross-plate-type flexible mobile guiding mechanism. Combining stiffness, maximum travel and displacement resolution, it is applicable to precision and ultra-precision machining.
Solving a North-type energy balance model using boundary integral methods
Authors: Samuelsberg Aksel , Jakobsen Per Kristen
Published: May 2024

Abstract. Simplified climate models such as energy balance models (EBMs) are useful conceptual tools, in part because their reduced complexity often allows for studies using analytical methods. In this paper, we solve a North-type EBM using a boundary integral method (BIM). The North-type EBM is a diffusive one-dimensional EBM with a non-linear albedo feedback mechanism. We discuss this approach in light of existing analytical techniques for this type of equation. Subsequently, we test the proposed method by solving multiple North-type EBMs with a zonally symmetric continent featuring an altered ice-albedo feedback dynamic. We demonstrate that the introduction of a continent results in new equilibrium states characterized by multiple ice edges and ice belts. Furthermore, we show that the BIM serves as an efficient framework for handling unconventional ice distributions and model configurations for North-type EBMs.
The multiple understandings of wind turbine noise: Reviewing scientific attempts at handling uncertainty
Authors: Kirkegaard Julia K. , Cronin Tom H. , Nyborg Sophie , Frantzen Daniel N.
Published: May 2024

Abstract. The noise from wind turbines has been an issue in the planning and development of wind power for many years, giving rise to both controversies during the deployment of onshore wind farms as well as a significant amount of research by various communities of scientists, or what we treat here as epistemic communities. Despite iterative attempts at fixing the noise issue through investments into technological developments and regulatory determination of allowable decibel noise levels, noise remains a contested and difficult object to find solutions to. In the Co-Green project, we instigated a social science-based study founded in Science & Technology Studies (STS) to look at why and how it is that noise continues to be so controversial. We do this through a narrative literature review of three different epistemic communities – the technical, health-based, and social acceptance literatures – tracing the emergence of the knowledge object of wind turbine noise. We illustrate how noise remains an ‘unruly knowledge object’ that defies stabilisation within and between the three epistemic communities: Instead, noise is understood as fundamentally different things across the three communities, fuelling the controversies over the solutions proposed, where the “fixes” might sometimes not address what was intended. We end by pointing to the potential benefits of more interdisciplinary engagement between epistemic communities and as well as to – in the context of science for policy – probe the potential value of finding ways to translate qualitative research findings into noise (and other) regulations.

Published: May 2024

У статті розглянуто такі властивості закону про кримінальну відповідальність, як стабільність та динаміка. При проведенні дослідження встановлено взаємозалежність між вказаними правовими категоріями. Констатовано, що в умовах воєнного стану пріоритет має динаміка закону про кримінальну відповідальність. Як перспективу при формуванні нового кримінального законодавства закладено пріоритет стабільності закону про кримінальну відповідальність. У дослідженні констатовано відсутність Закону України, який би визначав порядок направлення проєктів законів до Національної академії наук України для проведення юридичної (правової) експертизи. Запропоновано такий механізм перевірки законопроєктів передбачити в Регламенті Верховної Ради України. У статті підтримано положення проєкту КК України щодо закріплення принципу стабільності кримінального законодавства. Установлено, що в національному законодавстві нормативно закріплено принцип стабільності закону лише в п. 4.1.9. ст. 4 Податкового кодексу України від 2 грудня 2010 р. Аналіз відповідних положень проєкту КК дав змогу зробити певні рекомендації щодо їх удосконалення: по-перше, потребує самостійної регламентації презумпція знання кримінального закону та стабільність Кримінального кодексу; по-друге, закріплення конкретних часових меж внесення змін до КК України негативно вплине на реалізацію динаміки закону про кримінальну відповідальність; по-третє, нормативне врегулювання механізму внесення змін до КК України не гарантує дотримання таких норм і потребує встановлення відповідальності за їх невиконання.
СТРАТЕГІЯ ТА ТАКТИКА ДЕРЖАВНОЇ ПОЛІТИКИ У СФЕРІ ЗАБЕЗПЕЧЕННЯ ПРОДОВОЛЬЧОЇ БЕЗПЕКИ УКРАЇНИ
Authors: Кузьмічов Олексій Дмитрович
Published: May 2024

Статтю присвячено визначенню кроків для покращення стратегії та тактики державної політики у сфері забезпечення продовольчої безпеки України. Методологічною основою дослідження є компаративний, системно-структурний та формально-логічний методи. Їх використання дало змогу з’ясувати загальний механізм реалізації державної політики, а також дослідити досвід стратегічного планування реалізації державної політики у сфері забезпечення продовольчої безпеки в провідних країнах-членах Європейського Союзу. При проведенні дослідження використано вітчизняну та закордонну юридичну літературу, яка присвячена інструментам публічного адміністрування й особливостям реалізації державної політики у сфері забезпечення продовольчої безпеки в окремих країнах-членах ЄС, а також в Україні. У результаті проведеного дослідження автором констатовано, що в Україні не сформовано механізму безперервності планування стратегії та тактики державної політики у сфері забезпечення продовольчої безпеки України. Як наслідок, наразі державна політика у цій сфері публічного адміністрування здійснюється без чітко визначеної системи стратегічних цілей та завдань. Обґрунтовано наукову позицію про те, що механізм формування та реалізації державної політики у сфері забезпечення продовольчої безпеки має бути визначений на рівні окремого закону про продовольчу безпеку України. Він має містити детальну процедуру розробки, затвердження та виконання національної стратегії й тактики державної політики у сфері забезпечення продовольчої безпеки України. Загалом, позитивно оцінюючи проєкт розпорядження Кабінету Міністрів України «Про схвалення стратегії продовольчої безпеки на період до 2030 року», ми пропонуємо доповнити його змістовну частину такими елементами: механізмом реалізації в Україні загальновизнаних на рівні ЄС принципів забезпечення продовольчої безпеки країни; механізмом залучення України до забезпечення глобальної продовольчої безпеки; а також механізмом реалізації регіональної продовольчої безпеки в контексті співпраці органів місцевого самоврядування та органів державної влади в цій сфері. Окрему увагу варто приділити залученню ІТ до забезпечення продовольчої безпеки України, а також формування механізму реальної співпраці держави з інституціями громадянського суспільства у сфері забезпечення продовольчої безпеки України.

Стаття висвітлює проблеми доказування в цивільному процесі у справах про розірвання шлюбу. Внаслідок повномасштабної війни попит на розлучення збільшується. У сприйнятті закінчення стосунків, розірвання шлюбу відіграє важливу базову роль, адже фактично ставить перед eже експодружжям важливі питання утримання дітей, режиму побачень та процесу виховання, розподілу спільно нажитого майна та інших питань. Фактично, розірвання шлюбу є юридичним та психологічним рубежем для подружжя, проходження якого є важливим елементом як для громадян, так і для суспільства загалом, адже забезпечує можливістю створення нових, можливо, більш міцних сімей. В Україні доступні два способи розірвання шлюбу: – через РАЦС – якщо немає неповнолітніх дітей та при бажанні обох з подружжя припинити шлюб; – через суд – у разі наявності неповнолітніх дітей або при небажанні одного з подружжя розірвати шлюб. Згідно зі статистикою Міністерства юстиції України, кількість розірваних шлюбів за 2022 рік становить: 17 893, зокрема 1 093 розлучення через суд. Водночас указана статистика потребує доповнення від судових органів, адже через брак фінансування, порушення строків підготовки рішень, не всі судові рішення про розірвання шлюбів могли потрапити для відображення в статистиці за відповідний рік. На підтвердження вказаного правники у сфері сімейного права, неодноразово в ЗМІ повідомляли про збільшення запитів на розірвання шлюбу щонайменше вдвічі порівняно з попереднім роком [2, с. 175]. У статті йтиметься саме про судовий варіант припинення шлюбу та процес доказування у цьому виді цивільних спорів. «Кожна сторона повинна довести ті обставини, на які вона посилається як на підставу своїх вимог або заперечень» [3, ч. 1 ст. 81]. Цивільний процесуальний кодекс України, зокрема ст. 175, не містить переліку обов’язкових доказів, якими позивач повинен довести обставини, на які посилається, та, відповідно, додати до заяви про розірвання шлюбу. Водночас перелік таких доказів установлено судовим рішенням.

Diagnosis of leukemia remains one of the key problems in carrying out recreational activities in farms that are disadvantaged by this disease. In the Russian Federation, various methods are used to identify the causative agent of leukemia, including serological methods, one of which is enzyme immunoassay (ELISA). The principle of the indirect variant of ELISA is to identify a complex formed by an antigen immobilized on the surface of the wells of a polystyrene tablet and specific antibodies contained in blood serum samples or cattle milk. The present work is devoted to the study of the possibility of using a synthetic peptide, which is an amino acid sequence of epitopes of the gp51 protein of the leukemia virus, as an antigen for ELISA in the indication of the bovine leukemia virus. To develop the ELISA method, we designed and synthesized the antigen – synthetic peptide BLVPEP (NCKYSNQCGDQGSFYVNHQILFLHLK QCHGIFTLTWEIWNC). In order to best sensitize this peptide, the main parameters of the ELISA formulation were worked out. In particular, the optimal concentration of the peptide for sensitization of the tablet was determined - 1.0 micrograms/ml, blocking solution – 3% solution of skimmed milk powder, anti–species peroxidase conjugate - 1:40000, the reaction buffer of the interaction "antigen-antibody" - FSB-T (pH 7.3) was selected, the minimum titer of antibodies to the pathogen, detectable in the blood sera of cows with leukemia – 1:1600. The ELISA method presented in this paper can be used as a basis for creating a test system for detecting the causative agent of bovine leukemia and find wide application in veterinary practice for serological diagnostics.

In the poultry industry, feed additives with positive effects on the condition of the poultry are constantly used. Antimicrobials are used for this purpose. However, the indiscriminate use of antibiotics accelerates the spread of antibiotic resistance among bacteria. Hence, researchers have increased interest in finding alternative feed additives. Plant extracts are of considerable interest in this matter as they have a wide range of biological properties including antibacterial activity. Phytobiotics, have been found to increase productivity, feed conversion ratio, safety and meat quality. Among the potential phytobiotics, oak bark extract (Quercus cortex) should be emphasized, the activity of which is associated with the content of more active substances. With this in mind, the purpose of this work was formulated to study the effect of Quercus cortex extract and the feed antibiotic Biovit 200 based on 20% chlorotetracycline on feed digestibility, its slaughter properties and the content of chemicals in the body of broilers.The results obtained during the study suggest that the use of Quercus cortex extract (at a dose of 0,2 ml/kg) both alone and in combination with Biovit 200 (at a dose of 0,63 g/kg w.m./day contributed to an increase in the EIP index, digestibility coefficients. An excess in slaughter yield in I, II and III groups over the control group was recorded.

760 samples of biological material from various regions of the Russian Federation were studied, 320 isolates of yeast fungi were isolated, which amounted to 42.10% of the total number of samples. Of the 760 samples, 29.0% belonged to cattle, 11.8% to small cattle, 13.0% to horses, 1.6% to camels, 7.2% to cats and 17.5% to dogs, 1.8% to raw milk and 0.8% to environmental objects (OVS). Most of the isolated isolates (240) of yeast fungi belonged to fungi of the genus Candida, which amounted to 75%. The species diversity of fungi of the genus Candida is represented by 15 species. The largest number of isolates belong to the species Candida albicans, Candida catenulata, Candida kefyr Candida krusei, Candida membranifaciens, Candida pararugosa and Candida tropicals. These species of fungi of the genus Candida are known as pathogens of fungal infections in humans and animals. The species diversity of species not belonging to the genus Candida is limited to 7 species in 5 genera – Geotrichum, Malassezia, Rhodotorula, Saccharomyces and Trichosporon. The fact of the development of resistance of some yeast species to the most commonly used antifungal drugs (fluconazole and voriconazole) has been established. It was revealed that 30% of the studied isolates of the genus Candida are resistant to fluconazole, 32% are dose–dependent, 38% are sensitive, 28% are resistant to voriconazole, 30% are dose–dependent, 42% are sensitive. Isolates not belonging to the genus Candida showed resistance to fluconazole 19%, 38% - dose–dependent, 43% - sensitive, voriconazole – 23% – resistant, 18% – dose–dependent and 59% - sensitive. The proportion of isolates of yeast fungi resistant to fluconazole and voriconazole isolated from animals is quite large, in some cases it is up to 50% (C. tropicalis). A high level of resistance was found in isolates of Candida albicans, Candida catenulata, Candida rugosa and Candida pararugosa, which can significantly complicate the treatment of infections caused by them and contribute to the worldwide problem of antibiotic resistance.

The article presents the anatomical features of the gluteal group of extensors and supinators of the hip joint in a Maine Coon cat, which are absent in the available literature. The Maine Coon is the largest of the numerous breeds of domestic cats. To date, the anatomy of cats, and even more so the age, sex, breed, and species characteristics remain poorly understood, while the study of the specific anatomical features of the pelvic limb muscles in animals is one of the urgent tasks in the field of comparative anatomy and practical veterinary medicine. We have established that the muscles of the gluteal extensor group belong to different types of muscles: the middle gluteal is dynamic, the additional and deep gluteal, the pear–shaped is dynamostatic, with appropriate functional abilities. The research was carried out at the Department of Anatomy and Histology of Animals named after Professor A.F. Klimov, Moscow State Academy of Veterinary Medicine and Biotechnology – MBA named after K.I. Scriabin."The sectional material – pelvic limbs (n=8), selected from a domestic cat, without external signs of musculoskeletal pathologies, served as a material for research. Methods of fine macro- and microanatomic dissection were used, followed by functional analysis of the studied structures and skeletotopic projection of points of attachment of muscle parts. On the basis of the conducted research, we have established the skeleto-topical features of the anatomical formations on the pelvic and femur bones. It has been convincingly shown that the main extensor of the hip joint in the Maine Coon is the gluteus medius muscle. It is the most powerful among the gluteal muscles and belongs to the dynamic type in its internal structure. At the same time, the additional gluteus muscle, being a muscle of the dynamo-static type, performs a more static function of the joint, that is, when it is extended, it holds the joint in this position for a longer time. The piriformis and deep gluteus muscles, anchored by the bases at different levels, are synergists in hip abduction.

The skin, through its structural features, while performing its functions, participates in the formation and establishment of adaptive processes in the bird’s body in response to the influence of factors of both exogenous and endogenous origin. The purpose of this work was to study the regional and agerelated features of the histostructure of the skin of Hybrid Converter NOVO cross tur keys raised in the conditions of a poultry farm in the Tyumen region. Macroscopic and microscopic studies of the skin of turkey poults were carried out in the laboratory of the Department of Anatomy and Physiology. It has been established that turkey skin has 3 layers: epidermis, dermis and subcutaneous layer. The epidermis consists of the horny and germinal layers, the dermis of the superficial and deep layers, where feather follicles lie. The stratum corneum of the epidermis is represented by corneocytes, and the germinal layer is represented by keratinocytes. The thickness of the skin of the back is less than that of the abdomen. At the same time, the thickness of the stratum corneum on the back is less than that of the germinal layer up to 105 days of age. On the abdomen, the thickness of the horny and germinal layers is almost the same at all ages. There is a thickening of the stratum corneum on the abdomen compared to the skin of the back. The skin is thickest on the abdomen and gradually thins towards the back. The epidermis is thin. The dermis is characterized by a dense interweaving of collagen fibers. Smooth muscle fibers in the skin and hair follicles develop by 42 days, and increase in volume by 105 days of age. The thinning of the feather cover in the sternum and belly area, caused by mechanical stress when poultry are kept on the floor, contributes to an increase in the absolute thickness of the epidermis in this area (about 3.5 times greater than in the back area), which is associated with its participation in protecting the skin from mechanical impacts damage.
