La figura del juglar en la mediación para la lectura del Cantar de mio Cid: el caso de Jaque al Rey (2012), de Francisco Rincón Ríos
Authors: Crespo Vila Raquel
Published: December 2024

Partiendo de una revisión previa que corrobora la presencia de la figura del juglar en el conjunto de recreaciones cidianas contemporáneas y de un somero repaso para la caracterización de dicho perfil medieval, el presente trabajo tiene por objeto la novela Jaque al rey, firmada por Francisco Rincón Ríos y publicada en el año 2012. Dirigida a un público adolescente, tal novela pretende aproximar a tales lectores el conocimiento de un clásico de las letras medievales castellanas como es el Cantar de mio Cid. Desde este planteamiento, el artículo se centra en el carácter protagónico del juglar llamado don Armillo, con el propósito de desentrañar, en primera instancia, el basamento histórico y filológico de tal personaje; pero, sobre todo, su papel en la mediación literaria que se pretende en la novela y que, a tenor de esa naturaleza juglaresca, incide en tres aspectos esenciales para comprender el cantar épico medieval en toda su complejidad: el componente geográfico de aquella composición, el potencial escénico de sus versos y, en fin, su valor simbólico
Liquidation of the Dostoevskys’ Book Business
Authors: Stepchenkova Valentina
Published: December 2024

A. G. Dostoevskaya planned to publish her husband’s works until the end of her life and hoped to transfer the book business to her children. This is evidenced by the entries in her testamentary notebook of 19020–1911, which contains detailed instructions on publishing issues for the heirs. In 19040–1906, on the 25th anniversary of her husband’s death, Anna Grigoryevna printed the sixth (jubilee) and seventh (cheaper) editions of the Complete works of Dostoevsky. However, the release of these books, the pinnacle in her publishing practice, coincided with tragic events in Russian history — the Russo-Japanese War and the First Russian Revolution, as a result of which A. G. Dostoevskaya had to end her 38-year publishing career. Based on unpublished archival materials of the publisher (notebooks, notebooks and correspondence), the article analyzes a set of reasons that contributed to this decision. At the beginning of the 20th century, A. G. Dostoevskaya and the writer’s children found themselves deeply in debt for a number of reasons: due to their lack of working capital after a deal with the publisher of the Niva magazine A. F. Marx in 18940–1896, the rise in price of paper and printing works, a change in reader interest from collections of works to political pamphlet publications and a decline in sales in the book market. The situation was aggravated by the discussion in the government regarding a reduction in the period of ownership of literary property by the heirs of famous authors, the deteriorating health of the publisher and the categorical demands of her daughter to sell literary rights and stop book-related activities. The rights to publish Dostoevsky’s works were sold in 1910 to the Enlightenment Association. Another stage of the traditional history of the great writer’s legacy has begun, but without the participation of his family

Introduction. Impact of the jamming leads to the high losses since it decreases effectiveness of radiolocation systems, anti-aircraft missile systems and communication systems. Strategies of forming and setting of the jamming are improving and the power of the jamming increases. In this regard, it is important to improve jamming cancellation systems.
The task of the improvement for based on matrix calculations methods of the jamming cancellation is actual considering the breakthrough development of the computational methods which allows realization by digital circuit engineering. These include the most modern machine learning algorithms aimed at solving signal processing tasks.
The requirement of the stable operation is important for the jamming cancellation systems under conditions of uncertainty. Other demand is an operation in the real time and a simple hardware implementation.
The purpose of the paper is to increase the efficiency of the jamming cancellation in the antenna system (under conditions of uncertainty) based on the new randomized computation methods and their realization by the matrix-processor architecture.
Results. The approach based on singular value decomposition and random projection is proposed. It provides effective jamming cancellation in the antenna systems under conditions of uncertainty that is, the sample has small length, there is an own noise of the measuring system, the input-output transformation matrix have undefined numerical rank and there is no prior information about useful signal.
Communication. The increase of the efficiency of the jamming cancellation includes the increase of the stability and jamming cancellation coefficient, and the reduction of the computational complexity.
The increase of the jamming cancellation coefficient is provided by use of stable discrete ill-posed inverse problems solution methods of the signal recovery based on random projection and singular value decomposition. The decrease of the computational complexity is achieved by the realization of random projection and singular value decomposition as the processor array which makes parallel computations.
Keywords: information technology, jamming, machine learning, algorithms, singular value decomposition, random projection, conditions of uncertainty, signal recovery.

Recreational potential and educational opportunities of summer camps for children
Authors: Bondar Taras
Published: December 2024

Background and Study Aim. The decline in the health of school-aged children is a cause for concern and necessitates effective solutions. Summer camps can potentially address this negative trend. This study aims to examine the recreational potential and educational opportunities of summer camps and their impact on children's development.
Materials and Methods. The study involved 183 student interns undergoing pedagogical practice in summer camps. A survey was conducted using a specially designed questionnaire. Additionally, documentation from the Kharkiv Regional Department of Physical Education and Sports (Ukraine) was used for data collection. The obtained data were processed using descriptive statistical methods.
Results. The results indicate that summer camps significantly enhance children's awareness of their own health, improve physical activity levels, and boost psycho-emotional well-being. The density of health activities in out-of-town camps is notably higher than in educational institutions. During the summer, 325 health events and sports competitions were held in children's health and recreation centers, averaging 8.56 per session. In general educational institutions, the average is 7 such events per academic year, while in school-based camps, this figure is 1.71. The analysis of materials also showed that recreational activities, such as tourist and local history hikes and excursions, are more actively utilized in children's health and recreation centers. In out-of-town health and recreation centers, an average of 1.61 excursions and hikes are held per session (1.82 per group). In school-based camps, an average of 2.57 excursions and hikes (1.57 per group) are conducted. In general educational institutions, similar school-wide events are not held at all, as classes go on hikes only once a year.
Conclusions. Summer camps have a significant positive impact on the physical, psycho-emotional, and social development of children. Camps contribute to the formation of a conscious attitude towards personal health and increase the level of physical activity.

Published: December 2024

This study explored the phenomenon of maxim flouting in the utterances of John Terry and Ashley Cole during the Dubai Eye 103.8 Sports Podcast. It tried to describe flouting maxims by John Terry in the podcast and the similarities and differences between the flouting maxim in the utterances of John Terry and Ashley Cole. A descriptive qualitative approach was employed to analyze and interpret the data, utilizing Grice's (1975) theory of conversational maxims as the theoretical framework to explain instances of maxim flouting in the cooperative principle observed in the speakers' utterances. Data collection was conducted through document analysis. The findings revealed that John Terry's utterances contained several instances of maxim flouting: 25 occurrences of flouting the maxim of quantity (64.8%), 1 instance of flouting the maxim of quality (3.7%), 8 instances of flouting the maxim of relation (20.7%), and 4 instances of flouting the maxim of manner (10.8%). In contrast, Ashley Cole's utterances included 21 occurrences of flouting the maxim of quantity (80.7%), 2 instances each of flouting the maxims of quality and relation (7.7% each), and 1 instance of flouting the maxim of manner (3.9%). The study also identified a key similarity: both speakers predominantly flouted the maxim of quantity in their utterances. However, a notable difference was observed in the frequency and distribution of the flouted maxims between the two speakers.

Authors: Radionov Y. D. , Kashtan V. Yu. , Hnatushenko V. V. , Kazymyrenko O.V.
Published: December 2024

Context. Aircraft detection is an essential task in the military, as fast and accurate aircraft identification allows for timely response to potential threats, effective airspace control, and national security. The use of deep neural networks improves the accuracy of aircraft recognition, which is essential for modern defense and airspace monitoring needs.
Objective. The work aims to improve the accuracy of aircraft recognition in high-resolution optical satellite imagery by using deep neural networks and a method of sequential boundary traversal to detect object contours.
Method. A method for improving the accuracy of aircraft detection on high-resolution satellite images is proposed. The first stage involves collecting data from the HRPlanesv2 dataset containing high-precision satellite images with aircraft annotations. The second stage consists of preprocessing the images using a sequential boundary detection method to detect object contours. In the third stage, training data is created by integrating the obtained contours with the original HRPlanesv2 images. In the fourth stage, the YOLOv8m object detection model is trained separately on the original HRPlanesv2 dataset and the dataset with the applied preprocessing, which allows the evaluation of the impact of additional processed features on the model performance.
Results. Software that implements the proposed method was developed. Testing was conducted on the primary data before preprocessing and the data after its application. The results confirmed the superiority of the proposed method over classical approaches, providing higher aircraft recognition accuracy. The mAP50 index reached 0.994, and the mAP50-95 index reached 0.864, 1% and 4.8% higher than the standard approach.
Conclusions. The experiments confirm the effectiveness of the proposed method of aircraft detection using deep neural networks and the process of sequential boundary traversal to detect object contours. The results indicate this approach’s high accuracy and efficiency, which allows us to recommend it for use in research related to aircraft recognition in high-resolution images. Further research could focus on improving image preprocessing methods and developing object recognition technologies in machine learning.
POST PROCESSING OF PREDICTIONS TO IMPROVE THE QUALITY OF RECOGNITION OF WATER SURFACE OBJECTS
Authors: Smolij V. M. , Smolij N. V. , Mokriiev M. V.
Published: December 2024

Context. The significance of this work stems from the growing need for UAV technologies integrated with artificial intelligence, aimed at detecting and identifying objects on the surface of water bodies. Modern needs in water body monitoring, especially in the context of environmental monitoring, protection and resource management, require accurate and reliable solutions. This work demonstrates methods for improving the performance of neural networks and offers approaches for processing NN predictions, even if they are trained on irrelevant data, which increases the versatility and efficiency of the technology.
Objective. The goal of the work is to solve the problem of false recognition of objects on the surface of water bodies, which is due to a decrease in the accuracy threshold for the neural network. This provides more accurate and reliable detection, reducing the number of false positive predictions and increasing the efficiency of the system in general.
Method. It is proposed to add a stage of post-processing of NN predictions, which inherits concepts of min-max suppression used by YOLO models. This algorithm suppresses the re-detection of the object by the network and relies on the cross-sectional area of the detected rectangles. It uses a threshold value of 0.8 for the two points of the rectangle, which can effectively reduce the number of re-predictions and improve the accuracy.
Results. As a result of the implementation of the proposed algorithm and the script created on its basis, a result was achieved in which groups from several predictions are combined and filtered. The received data is stored in the database as found and detected objects. The proposed post-processing algorithm effectively removes redundant predictions while maintaining forecast accuracy. This ensures the reliability of the system and increases its performance in real conditions.
Conclusions. Detected images of objects on the surface of water bodies are stored in the database in the form of records with unique file name identifiers. After tests with pre-taken images algorithm proved it`s persistence against data duplication scenarios. This increases the efficiency and reliability of the monitoring system, ensuring accurate and timely detection of objects on the surface of water bodies.

Published: December 2024

Context. Significant challenges facing hardware developers of artificial intelligence systems force them to look for new nonstandard architectural solutions. One of the promising solutions is the transition from von Neumann’s classic architecture to neuromorphic architecture, which at the hardware level tries to imitate the work of the neural network of the human brain. A neuromorphic processor built as hardware implementation of a spiking neural network consists of a large number of elementary electronic circuits that structurally and functionally correspond to neurons. Thus, the design of hardware implementation of a spiking neuron as the basic building element of a neuromorphic processor is of great scientific interest.
Objective. The goal of the work is to design an analog spiking neuron hardware implementation with digital control of input signals by binary synaptic weighting coefficients.
Method. Designing is performed at the logical/schematic and topological levels of the design flow using modern tools of electronic design automation. All proposed schematic and layout solutions are verified and simulated using computer aided design tools to prove their functionality.
Results. The schematic and layout solutions have been developed and investigated for the hardware implementation of the spiking analog neuron with digital control of input signals by binary synaptic weighting coefficients to be the basic building element of a spiking neural network of the neuromorphic processor.
Conclusions. The proposed hybrid design of the spiking neuron hardware implementation benefits by combining the simplicity of analog signal processing methods in the neuron with digital control of the state of the neuron using binary weighting coefficients. The simulation results confirm the functionality of the obtained schematic/layout solutions and demonstrate the possibility of implementing logical functions inherent in the perceptron. The prospects for further research may include the design of hardware implementation for a spiking neural network core based on the developed schematic and layout solutions for the spiking neuron.

Сушіння є основним технологічним етапом підготовки посівного матеріалу до тривалого зберігання. Під час сушіння відбувається видалення надлишкової вологи з насіння до рівня, при якому припиняється мікробне псування та мінімізується ферментативна активність. Для збереження схожості та сили проростання посівне насіння зазвичай зневоднюють в конвективних сушарках при таких параметрах сушильного агента, при яких не відбувається перевищення гранично допустимої температури нагріву матеріалу. В статті викладені результати всебічних досліджень насіння дині сорту «Ананас» як об’єкта сушіння з метою розроблення енергоефективних режимів зневоднення. З застосуванням диференціального мікрокалориметра ДМКИ-01 проведені експериментальні та розрахункові дослідження теплоємності насіння дині та витрат теплоти на випаровування з нього вологи. Надана формула для розрахунку питомої теплоємності насіння дині в діапазоні змінювання відносної вологості від 10,4 до 37,5 % та температури від 32,5 до 92,5 °С. За результатами досліджень тепломасообмінних процесів під час конвективного сушіння насіння дині при температурах теплоносія 40, 50 та 60 °С та експериментально визначеними теплофізичними властивостями проведені розрахунки критерію Ребіндера і густини теплових потоків на поверхні матеріалу. На підставі сумісного аналізу одержаних експериментальних та розрахункових даних зроблено висновок про те, що задля раціонального використанні енергії та збереження якості та схожості  насіння дині, його доцільно конвективно сушити при температурі теплоносія 40 °С до вологості  15 % відн.. Після досягнення насінням вологості 25% відн. необхідно знижувати енергопідведення, бо теплові потоки на поверхні матеріалу з цього моменту процесу сушіння стабілізуються на дуже низькому рівні.

Фруктово-овочева продукція представляє собою цінну харчову сировину з високою біологічною цінністю. Суттєвим недоліком є сезонність і висока схильність плодово-овочевої сировини до псування, що вимагає використання спеціальних технологій і обладнання для її переробки. Одним із доведених методів інтенсифікації гідромеханічних процесів в дисперсних системах при зниженні непродуктивних витрат енергії є застосування обладнання в якому реалізований принцип дискретно-імпульсного введення енергії (ДІВЕ). Для збільшення дисперсності твердої фази дослідної системи при одержанні пюре з гарбуза використовували гомогенізацію зразків в проточному роторно-пульсаційному апараті (РПА) циліндричного типу з поступовим нарощуванням гідромеханічного впливу за рахунок збільшення циклів обробки. Встановлена залежність динамічної в'язкості гарбузового пюре від тривалості гідромеханічного впливу. Дослідження довели, що зі зменшенням дисперсності в результаті проведення тривалої гідромеханічної обробки при диспергуванні гарбузового пюре значення динамічної в’язкості зменшуються. Водночас збільшується однорідність і рівномірність розподілення дисперсної фази по усьому об‘єму суспензії. З підвищенням температури в'язкість всіх дослідних дисперсних систем зменшується, що можна пояснити зниженням енергії міжмолекулярних взаємодій, яка перешкоджає переміщенню молекул. У стані спокою, при витримуванні системи впродовж 24 год. і більше, надлишок вільної поверхневої енергії високодисперсних частинок призводить до стабілізації системи із укрупненням частинок дисперсної фази і незначного підвищення динамічної в’язкості. Проведені дослідження реологічних властивостей довели, що метод обробки за допомогою використання механізмів ДІВЕ є ефективним для одержання однорідного і стабільного в процесі зберігання пюре з гарбуза.

На сьогоднішний день в Україні має місце суттєве недопостачання енергетичних ресурсів (зокрема електроенергії) на фоні різкого загострення екологічних проблем. Ця тенденція є актуальною і в глобальному масштабі, оскільки використання  викопного палива, як основного джерела енергії, є причиною природніх катаклізмів. Такий стан справ  зумовлює необхідність широкого застосування так званих відновлювальних  джерел енергії. Це стосується енергії  сонця, вітру, геотермальної і таке інше. Розвиток відновлюваної енергетики нерозривно пов’язаний з розвитком біотехнологій, зокрема біоелектрики. Розробка  цього напрямку в біотехнології  передбачає вирішення актуальних завдань сьогодення, зокрема розроблення екологічно безпечних технологій генерації електричної енергії. Розвиток подій за таким сценарієм передбачає  зменшення викидів парникових газів та інших забруднювачів у навколишнє середовище, гарантію енергетичної безпеки, а також розроблення підгрунття для створення мережі стаціонарних джерел біоелектрики, як частини інфраструктури для автомобілів на паливно-коміркових елементах.
Електрична енергії відіграє важливу роль і у нашому повсякденному побутовому житті, a її споживання постійно зростає. Оскільки традиційне її виробництво на основі викопного палива має величезні економічні та екологічні проблеми, то подолання їх можливе за рахунок впроваджуються біотехнологій. Потреба в біоенергії стає невідворотною для заміни викопного палива. Власне природний фотосинтез пропонує засоби і методи для цього і передусім через застосування рослин. Наземні рослини подекуди вже використовувалися як джерело біоенергії, і це використання буде тільки зростати в майбутньому, незважаючи на можливі супутні проблеми.
Дане дослідження стосується нової технології виробництва електроенергії, а саме, біотехнології, тобто використанням водних екстрактів різних рослинних ресурсів. Деякі рослини в природі мають властивості накопичувати в клітинах біологічно активні сполуки здатні до створення електролітичного середовища, власне вони придатні для виробництва електроенергії, які можна посилювати.
HYDRO-MECHANICAL PROCESSING OF RAW BEEF BY MASSAGING: THEORETICAL BASICS AND PRACTICAL
Authors: Вербицький Сергій Борисович
Published: December 2024

Upgrading of the equipment for hydro-mechanical processing of raw meats is important both in terms of ensuring the proper profitability of production and in terms of providing consumers with valuable protein meat products of excellent taste. Salting of raw meats, which is related to hydro-mechanical processing, is a complex process embracing mass exchange, transformations of protein and other substances, changes in the water-holding capacity of meat, changes in its microstructure, etc. There are different approaches to the machine and apparatus design and technological modes of hydro-mechanical processing of raw meats. Meat massagers / tumblers used in industry are equipped with devices for cooling and vacuuming the working space. Active research is being conducted to determine the rational duration of work / standstill during processing of raw materials in a drum. For beef, it is recommended to use the mode of alternating 30 min of work with 30 min of standstill for 8-12 h or other modes. The purpose of the article is to present and logically substantiate the results of studies of massaging the processing of meat raw materials in the drum of the massager under different modes of technological processing. Massaging of raw meats was carried out using a laboratory unit for wet salting of meat raw materials (drum massager) Ya5-FMS of our own design. Rheological characteristics were determined using an electromechanical universal testing machine SANS CMT2503. The duration of salting of raw meats depends on their type and quality characteristics, morphological composition, pH, degree of autolysis, mass and shape of meat cuts, quantity, quality and temperature of brine, as well as on the efficiency of the equipment used. Even more effective penetration of curing ingredients is achieved by using a pulsating vacuum, in which the processed meat raw materials are exposed to alternating loads: atmospheric pressure – vacuum. An increase in the intensity of hydro-mechanical processing of raw meats causes corresponding changes in the structure of muscle fibers – their swelling, the occurrence or increase of transverse-slit integrity violations, disruption of membrane structures, loosening and swelling of myofibril proteins. All of the above indicates that the use of pulsating vacuum and drum cooling not only improves, but also significantly accelerates the process of wet salting of raw meats raw materials in the production of ham products. The use of vacuuming in general and pulsating vacuuming in particular contributes to the intensification of the process of wet salting of raw meats. Therefore, the use of massagers with cooling and a pulsating vacuum system is an optimal design solution in terms of product quality and acceptable production profitability for meat processing enterprises.

The Russian World in Tajik Academic Discourse: Research Directions, Problems, Prospects
Authors: Iskandarova Diloro
Published: December 2024

The interest of the Tajik academic community in the Russian language, literature, and culture has remained consistently high for a considerable period. Following Tajikistan’s independence, this interest has not diminished, but rather, it has been reinforced. In accordance with the Constitution of the Republic of Tajikistan, Russian is the language of interethnic communication. Tajiks, who were historically bilingual in ethno-contact zones, received Russian as a second or third language during the Soviet era. Nevertheless, despite the extensive scholarly literature, the issues of a comprehensive interdisciplinary study of the Russian language, culture, and literature in a comparative manner remain largely unaddressed. This article examines the issue of studying Russian linguoculture in descriptive and comparative terms, as well as in a bilingual context. In examining this topic, the research of the academic school “Applied Linguistics in the Republic of Tajikistan,” led by D. M. Iskandarova, and the Research Laboratory “Interdisciplinary Applied Research” of the Russian-Tajik (Slavic) University serve as a foundation for this discussion. The objective is to examine the status of interdisciplinary research on the Russian language, literature, and culture within the Tajik scholarly discourse, as well as the functioning of the Russian language in bilingual communicative environments. This study examines the perception and reflection of the concept of “Russian” in the linguistic consciousness of the youth of Tajikistan. The analysis of this perception provides insight into how the Russian linguocultural space is reflected in the linguistic picture of the world of a bilingual individual. Additionally, examples of interdisciplinary studies are provided, which present a comparative analysis of the empirical material of Tajik scholars. The interest in Russian literature, the Tajik-Russian literary and cultural ties, the translations of Russian poets and writers into Tajik, as well as the appeal of Russian poets and writers to the literary heritage of Tajik-Persian poets and thinkers, has remained consistently high. This article presents an analysis of the works of Tajik literary scholars on this issue. A review of the presence of the Russian language, literature, and culture in the scholarly discourse of Tajikistan enables the identification of existing problems and the delineation of prospects for the development of research in these areas, as well as the formulation of recommendations for the advancement of scholarly collaboration between Russia and Tajikistan.
Coats of Arms, Fabrics, and Dyes in Russia in the Early Modern Period: Was there a Hierarchy of Colour?
Authors: Mustafin Arthur
Published: December 2024

The colours red and green played a significant role in the cultural and artistic traditions of the Russian Middle Ages. This conclusion is supported by several studies that employed quantitative analysis methods. Nevertheless, the issue of colour in studies on early modern Russia remains a relatively marginal concern. In modern historiography, the history of the attitude to colour in European society in the Middle Ages and the modern period has been studied in detail, largely due to the work of Michel Pastoureau. His conclusions and methodological developments are relevant in the study of the hierarchy of colour in Russia in the eighteenth century, which is the subject of this article. The work pays close attention to noble coats of arms, coloured fabrics and dyes, and delves deeply into the wills of noblemen and merchants, monastery revenue and expenditure books, customs books, and legislative sources. The results of the quantitative research demonstrate that the colour blue is the most prevalent in both family coats of arms and the attire of nobles. The colour red is somewhat less prevalent, while green is frequently insignificant. It has been demonstrated that in Russia during the eighteenth century, the blue colour group represented the most expensive one. The described hierarchy of colour in Russian society was, in many respects, typical of that observed among the inhabitants of Western Europe in the early modern period. It can therefore be argued that one of the principal reasons for the shift in attitudes towards colour in Russia during the period under study was Western influence, which is explored in greater detail in this article.
Bosphorus Strait and Its Environs in Russian Written Sources of the 1830s
Authors: Olcay Türkan
Published: December 2024

In this article, Russian written sources of the 1830s are analyzed in terms of perception of the Bosphorus and its environs by the Russians. The author refers to Letters from the Anatolian Side of the Bosphorus by a Russian soldier published in the newspaper Severnaya Pchela in 1833; the notes by General N. N. Muravyov, Russians on the Bosphorus in 1833; Essays on Constantinople and Bosphorus and New Essays on Constantinople by an orientalist, diplomat and writer K. M. Bazili, who visited the Bosphorus in the first half of the 1830s. Their authors are people of different ages, education, and duties which makes it possible to present the Bosphorus through the eyes of the Russians, and at the same time from different, but complementary to each other, points of view. The letters of a Russian soldier contain information about the geographical features of the Bosphorus and its environs, as well as about the daily life of the people of that area. In the notes of General N. N. Muravyov, on the other hand, Bosphorus is described both as a strategic location for a military camp and as a study object of the history of this area. Finally, the description of the Bosphorus in the travel notes of K. M. Bazili is something more than a traveler’s observations since they contain historical information about this area and express nostalgic feelings for Istanbul, where Bazili was born. The proposed analysis makes it possible to introduce new information about the socio-cultural history of the Bosphorus and its environs in the 1830s, and present the image of Istanbul, and the Bosphorus in particular, through the eyes of foreigners.

Published: December 2024

Medicinal plants are a great source of active compounds that are used as raw materials to make medicines. They are also utilized extensively in phytotherapy and in food to help people maintain a healthy lifestyle. Beyond these factors, medicinal plants are a natural resource that is extremely important to the phytocenoses to which they belong. They help to maintain ecological balance and plant biodiversity. Plant species are either extinct or placed on red lists, which are categorized by the International Union for Conservation of Nature based on their sozological category, as a result of overexploitation, habitat fragmentation, climate change, and the introduction of invasive species. In order to preserve the equilibrium of the ecosystem, our study, which is an analysis of the specialized literature, outlines the primary threats to medicinal plants, the significance of protecting plant resources with therapeutic qualities, and some future perspectives that take into account the shared interests of all people in order to preserve the biodiversity of medicinal plants.
The Suitability of New Spring Barley Varieties (Ioana and Dumbrăvița) in the Beer Industry
Authors: CRISAN Ioana , RUSSU Florin , BOANTA Emilia-Ancuța , ONA Andreea D. , MUNTEAN Leon
Published: December 2024

The Ioana and Dumbrăvița spring barley varieties are intensive varieties, adapted to soils with high fertility and neutral to slightly alkaline pH. They are analysed in the context of agriculture and the beer industry. The hilly and pre-hilly regions of Transylvania, Moldova, and southern Banat are ideal for growing these varieties, which stand out for their vegetative vigor, good tillering capacity, and large grains, contributing to high agricultural yields. The connection of these varieties to the beer industry is significant due to the chemical composition of the barley grains. The proteins and starch in barley are essential in the malting process, influencing the amount of fermentable sugars and, consequently, the alcohol content of the beer. Beta-glucans, a type of fiber present in barley, affect the foam stability and clarity of the beer, while the minerals and vitamins in barley contribute to yeast health and fermentation efficiency. Thus, the quality of barley grains directly influences the taste, texture and clarity of beer, making these barley varieties essential for the production of high-quality beer.

Influence of constituents on strength and flowability in ultra high-performance concrete
Authors: Paul Anju , John Elson
Published: December 2024

Ultra-high-performance concrete (UHPC) boasts superior characterizations like excellent flowability, mechanical properties and durability. These features are achieved by adopting low water-to-binder ratio (w/b), good particle packing density and high dosage of steel fibers. This study mainly focused on the development of the optimized UHPC mixes by considering locally available materials. The impact of different composition of ordinary Portland cement (OPC) with different CaO/SiO2 ratio (4.31, 4.37, 4.49, 4.53, 4.60 and 4.82) on the compressive strength and flowability were investigated to ensure versatility across applications. The compressive strength of UHPC mixes by using various types of fine aggregates namely, manufactured sand, standard sand, river sand and quartz sand were also investigated. Also, the compressive strength as well as flowability of UHPC were studied by varying the fiber content of 0%, 1%, 1.5%, 2%, 2.5% and 3%. The results reveal that the compatibility of OPCs with varying CaO/SiO2 ratios has minimal impact, whereas different sand types significantly influence both flowability and compressive strength of UHPC mixes. Considering cost, availability and performance, M Sand and quartz sand can be used for the development of UHPC. Also, it was observed that increase in fiber content enhances the compressive strength while negatively influencing the flowability.
