ABSTRACT Although poultry meat production supports the livelihood and provides food security for billions of people worldwide, it is facing substantial challenges. The emergence of broiler breast myopathies (white striping, woody breast, spaghetti meat) at large scale is one of the most significant economic and welfare challenges that menace poultry production sustainability and for which there is currently no effective prevention, due to its unknown aetiologies. Here, by inviting and gathering several experts with diverse, but complementary disciplines, the objective of the present review is to highlight the current progress and knowledge on these myopathies. Five sections are presented, describing in detail the history and geographic occurrence of these breast myopathies, their macroscopic morphologies and microscopic characteristics, their putative aetiologies and causes as well as their underlying molecular mechanisms, and potential strategies and solutions. The is review summarizes both descriptive and functional mechanistic studies, highlights the complexity of these myopathies and the kinship between broiler genome, nutrition, and management, and outlines some of the promising molecular signatures. It aims to offer new fundamental frameworks for future investigations.

Background. Antenna arrays based on dual-polarization elements are used as radiating devices for modern and perspective radio communication systems. The main factor reducing the effectiveness of this approach is the presence of spatial correlation and cross-polarization between elements in the array. These effects can lead to a significant reduction in communication system capacity. Aim. Derive relationships based on the Kronecker model that allow to take into account the polarization properties of antenna elements when calculating the ergodic capacity of a multi-channel communication system. Investigate the influence of the cross-polarization parameter of the antenna element on the capacity. Assess the polarization characteristics of synthesized real antenna elements of various types and their impact on the capacity value. Methods. When deriving the basic relationships, methods of statistical radiophysics and electromagnetic analysis of the propagation channel were used. When synthesizing dual-polarization antenna elements, electrodynamic analysis methods based on Maxwell’s equations were used. Results. Based on the analysis using the derived relationships, it was established that the influence of the cross-polarization properties of the array antenna elements on the capacity of a multi-channel communication system becomes significant when the value of the cross-polarization parameters decreases below 10 dB. It is shown that synthesized real antenna elements of various types have high polarization isolation, which will lead to a slight decrease in the system capacity. Conclusion. The derived relationships and the developed methodology make it possible to estimate the change in the capacity of the communication system when taking into account the cross-polarization properties of the dual-polarization elements of the antenna array. This will allow to optimally select radiating elements for a given system. At the same time, the developed antenna elements of various types satisfy the imposed cross-polarization restrictions.

In this paper, we consider the issue of evaluating the vibration activity of complex multichannel aggregated hydraulic devices (AD) that combine in their design several simultaneously involved working elements (throttles, spool valves), flow channels of complex geometry, and control elements of various modes. In such conditions, it is extremely important to determine the contribution of the main elements to the resulting vibration characteristic of the device. To perform these works, it is necessary to develop an order and methodology for their implementation. The paper presents the main provisions of the developed methodology and the results of their implementation, including the following sequence of actions: Before installing the AD on the bench, the natural frequencies of free vibrations of the structure and its elements were determined by its free suspension. The results obtained were taken into account in the subsequent analysis. A program for measuring the vibration characteristics of the AD in various hydraulic modes of operation was developed. A map of vibration control points was compiled, determining the characteristics of specific structural elements of the AD design. A form of presentation and analysis of vibration characteristics at measurement points with a temperature distribution of the results over 1/3 octave frequency bands was developed. The planned tests were carried out, the results were analyzed, and the directions of work to improve the design of the AD and its test conditions were determined. The results of applying the above methodology in testing the vibration activity of the experimental AD sample made it possible both to determine the direction of improvement of its design and to optimize the operating modes of the main working bodies.

The purpose of this study is to evaluate the effectiveness of the inhibited Neftyanaya Emulsiya Hlorno-Kalievogo Termostabilizirovannogo - inhibited drilling solution - (NEHKT) drilling solution when drilling unstable rocks in red-colour sediments in a certain range of occurrence at a particular well. The study includes preparation of the solution, laboratory tests to determine the optimal components and their proportions, and conducting controlled experiments during which the solution was used in practice. During these tests, the inhibited NEHKT drilling fluid was used in real drilling conditions to evaluate its effectiveness. Conducting controlled experiments allowed evaluating of its ability to prevent complications during the drilling process and the success of the descent and cementing of the production column. The effectiveness of the inhibited NEHKT drilling solution was confirmed under conditions of drilling unstable rocks in red-coloured sediments in the range of 2000-2600 m at well No. 810 of the Nebitdag area. Drilling was also successfully conducted without complications when using the solution, which confirms its ability to ensure the stability of the drilling process and prevent possible problems associated with unstable rocks. The ability of the inhibited NEHKT solution to maintain its structural and mechanical properties in conditions of high mineralisation, penetrate the interplane space of clays, preventing their hydration and swelling, and bind all the water in the solution into persistent hydrates, which contributes to the stability and safety of the drilling process, is identified. Thus, the results of this study indicate the prospects and effectiveness of the inhibited NEHKT drilling solution in the context of ensuring a safe and stable drilling process for unstable rocks in red-coloured sediments.

The universe played a trick on me this year, as I thought my term as the Dermatology Nurses' Association's (DNA) President was coming to an end. However, the incoming president-elect informed me that she was unable to fulfill her responsibilities. While my first instinct was to react with anger, as this was a completely unexpected continuation of my duties, I decided to move forward with the theme she had chosen for the 2025 convention, which is “One for All.” Luckily for me, my Board of Directors of the DNA as well as the Program Planning Committee (PPC) rallied around me and gave a true meaning to the convention theme. This swift coming together showed what the theme meant to us, which is that each individual should act for the benefit of the group and the group should act for the benefit of each individual. It means there are no biases, everyone will be treated equally, and no one will be left behind. That being noted, the PPC has secured forward-thinking keynote speaker, Marilyn Dollinger, the Immediate Past President for American Nurses Association-New York, whose work in advocacy, for both nurses and patients, has spanned many years and embraces the notion that we should all speak as one voice to improve the care for our patients as well as advocate for our own physical and mental well-being. The PPC has been working hard and diligently on engaging speakers who meet the educational needs of our members as well as promoting interest in dermatology-related fields. We think the speaker lineup is exciting, as are the workshops on aesthetics and lasers. We believe that these areas are becoming extremely relevant based on the direction our practices are heading. During the conference, we will once again address the current condition of the DNA and the steps the Board of Directors of the DNA has taken to move forward and remain relevant. We would like to ensure that we continually emphasize solidarity and support all of our members. The DNA will consistently work toward supporting its members just as the members should work toward supporting the group. The 2025 conference in Orlando, FL, is gearing up to be our best one yet, with no shortage of activities in the Orlando area. We are looking forward to welcoming you and possibly your families to the Doubletree by Hilton at Sea World during the DNA convention on March 5–8, 2025 (Figure 1). We invite you all to experience the activities the DNA has planned. Our First Timers Reception, to be held on the first night of the conference, is always well attended and entertaining. You may also look forward to networking with established members and getting a new perspective on what you can contribute to the organization, as well as giving the established members new and innovative feedback. There will also be opportunities to visit the Exhibit Hall where the most current therapies will be on display as well as the posters developed by other nurse members. To keep the DNA vibrant, we really do need everyone to be as involved as possible and for it to be an all-hands-on-deck effort. I look forward to seeing you all in Orlando next year!FIGURE 1.: DNA 2025 Convention logo.Nancy J. Smail, RN

The article presents the analysis of Russian journals whose topics are related to the areas of activity of the Scientific Council on Control Theory and Processes at the Department of Energy, Mechanical Engineering, Mechanics and Control Processes of the Russian Academy of Sciences. Results of a survey of the leading Russian scientists in this field of science, including members of the council, helped to form a preliminary list of journals. The characteristics of these journals and their existing ratings are presented.It is noted that the well-known scientometric indicators do not allow one to evaluate the journals’ development pathways directly. A proposed indicator characterizes the average rate of change in a journal’s impact factor over a given time interval. The values of development indicators have been calculated and analyzed according to the Russian Index of Science Citation (RISC) and Scopus databases for the abovementioned journals included in these databases. The development pathways of some individual journals are considered.The article gives conclusions and recommendations that may be useful to the editorial staff – with a view to promoting their publications and to authors – in choosing a journal for publication.

The study of the properties of clay minerals and the creation of innovative drilling fluids based on them are extremely important aspects for improving the processes of extraction of natural resources, reducing operating costs, and increasing the energy efficiency of industrial operations. The purpose of this study was to explore the possibilities of developing a composition of drilling fluids based on the investigation of the properties of clay minerals for drilling and maintenance of wells in the conditions of the Gubadag deposit located in Turkmenistan. Statistical methods, experiments, and analysis were used in the course of the work. The results of the study showed that clay from the Gubadag deposit is characterised by low hydrophilicity and weakened structural stability, which is manifested in limited hydration energy and high filtration permeability. This leads to low viscosity, rheological, and structural-mechanical parameters of natural solutions. It follows from this that Gubadag clay is classified as a low-quality material. The prepared solutions from the above samples on different types of water have volumes in the range of 2-3 m³. However, after treating sea water with caustic soda, sample No. 2 generates more than 4 m³ of solution, significantly different from other samples. This highlights the need for additional research to optimise drilling fluid formulae, since it is important to determine the effect of clay materials on the properties of solutions and develop more adapted formulae that consider the specifics of the material and the conditions of its use in drilling wells. The practical significance of the results obtained lies in a significant improvement in the efficiency of drilling and maintenance of wells in regions with difficult geological conditions, offering new methods for preparing drilling fluids.
