Published: October 2024

В современных условиях развития инвестиционно-строительной сферы, характеризующихся необходимостью реализации политики технологического суверенитета, импортозамещения и создания собственных конкурентоспособных производств предприятиями, возникает необходимость совершенствования концептуальных и методологических основ активизации инновационного развития строительных предприятий. В статье выявлены особенности инновационной деятельности предприятий инвестиционно-строительной сферы, систематизированы научные подходы к построению методологии стратегического планирования инновационного развития, предложена методика анализа динамики характеристик и выявления трендов инновационного развития в строительстве. На основе проведенного анализа определены основные проблемы и тренды развития пространства инновационной деятельности в отрасли, предложены методы решения проблем и соответствующий инструментарий и направления их научного обоснования. При определении стратегических ориентиров развития строительных организаций, равно как и при определении стратегий развития мезоуровня, соответственно, должен учитываться прежде всего ценностно-ориентированный подход в проекции инновации ценности как устойчивого конкурентного преимущества предприятий, отраслей и регионов, а также стейкхолдерский подход в проекции формирования инновационной сети. Предложен новый подход к планированию и реализации стратегии инновационного развития строительного предприятия, включающий изменение инновационной парадигмы на основе инновации ценности и форсайт-прогноза строительной отрасли. Применение авторского подхода позволит повысить уровень инновационной активности в строительстве и обеспечить устойчивый рост инновационных конкурентных преимуществ предприятия в соответствии с целевыми ориентирами научно-технического и отраслевого развития. Показана целесо­образность совершенствования методологии формирования стратегии инновационного развития предприятий инвестиционно-строительной сферы на основании новой парадигмы инновации ценности, разработана логическая схема совершенствования методологии, позволяющая обеспечить опережающее развитие отечественных строительных предприятий на инновационной основе.
Управление предпроектной стадией инвестиционно-строительного проекта: аспекты внедрения нормативного и методического обеспечения деятельности организаций
Authors: Абдалов Роман Евгеньевич
Published: October 2024

В научной работе освещается вопрос нынешнего уровня развития технического регулирования в строительстве, в частности регулирования предпроектной стадии инвестиционно-строительного проекта (ICP). За последние годы в инвестиционно-строительной деятельности прочно укоренилась концепция управления жизненным циклом объекта недвижимости, подразумевающая сфокусированность на менеджменте каждого состояния системы — от идеи до ликвидации объекта. Тем не менее на практике участники строительных проектов осуществляют управление предпроектной стадией ICP без должного внимания и ответственности. Автором подчеркивается, что пренебрежительное отношение к работам предпроектной группы вызвано рядом причин, одна из которых — отсутствие понимания структуры и содержания предпроектной фазы и осознания возможной пользы ее результатов. Предполагается, что выступить в качестве теоретической базы и оказать содействие субъектам ICP в реальных условиях могло бы нормативное обеспечение. Для оценки предположения был проведен анализ системы отечественной нормативной базы и выделены элементы содержимого, которые будут полезны в применении при реализации предпроектной стадии ICP. По результатам проведенного анализа выяснилось, что нормативное обеспечение предпроектной фазы ICP несовершенно в объективе актуальной ступени эволюции строительной отрасли. Сегодня разработка универсального механизма для регламентирования предпроектной стадии ICP трудноосуществима, так как нас окружает колоссальное множество разнообразных и абсолютно не похожих друг на друга зданий и сооружений. Автором предлагается внедрение на организационном уровне нормативного и методического обеспечения (NMS), основанного на уже закрепленных нормах и правилах, имеющихся методиках и практических рекомендациях и выработанных корпоративных механизмах. Для формирования организациями строительной отрасли собственной модели ведения предпроектной стадии ICP автором разработана пирамида свойств NMS, доступно отражающая основные принципы, которыми должны обладать документы и информация, применяемая участниками ICP в практической деятельности. Учитывая векторы развития строительного сектора и национальной экономики России, предложенная авторская инициатива способна оказать всесторонний положительный эффект.

Published: October 2024

Устойчивое развитие городов и сельских поселений — одна из главных задач градостроительного планирования и проектирования, которая актуальна не только в России. В статье поднимаются вопросы обеспечения устойчивого развития городских территорий, а также основные проблемы, стоящие на пути достижения его целей, что является одной из наиболее актуальных тем современного техногенного общества. Определены критерии, необходимые для комплексной объективной оценки устойчивости развития городских территорий. На основе анализа многочисленных исследований теории устойчивого городского развития выделены пять основных закономерностей. Проведенный анализ показал, что применительно к урбанистическим представлениям, учет закономерностей городского развития территорий города снижает конкурентоспособность и инвестиционную привлекательность городской среды. В этой связи закономерности развития городских пространств имеют дуальную и экономическую природу, с одной стороны, учитываются особенности и разнообразие, экономической деятельности систем городского хозяйства, с другой, тенденции выравнивания и конвергенции устойчивого развития городских территорий. В исследовании дано пояснение сущности закономерностей социально-экономической и технологической системы города. Выделены основные закономерности городского развития как основы формирования нового управленческого функционала устойчивого развития городских территорий. Исследуя условия и принципы обеспечения устойчивого развития городов, автор пришел к выводу, что системное решение возникающих и множащихся проблем городского развития не может быть обеспечена без приоритета города как саморазвивающейся системы над его составляющими, и синтеза основных направлений урбанистики: технологического, социального и эстетического. Логическим следствием обеспечения системного единства станет расширение предметной области урбанистики и развитие градостроительных концепций, в основе которых цели реструктуризации недвижимости городских пространств.

Authors: Звонов Илья Александрович
Published: October 2024

В настоящий момент перед российской экономикой стоят большие вызовы в области технологического развития. Наука и технологии обретают новую роль как основополагающие элементы решения многих национальных и глобальных проблем. Ожидается, что в ближайшие 10–15 лет приоритетами научно-технологического развития России станут те направления, которые позволят получить новые научные и научно-технические результаты, создать технологии, являющиеся основой инновационного развития внутреннего рынка продуктов и услуг, устойчивого положения страны на внешнем рынке, и обеспечат, в том числе, переход к передовым цифровым, интеллектуальным производственным технологиям и высоким технологиям. Соответственно, становятся необходимы системные изменения подходов к научно-технологическому развитию регионов для достижения технологического суверенитета в области критических и сквозных технологий. А это требует консолидации усилий федеральных органов государственной власти, органов государственной власти субъектов РФ, научно-образовательного и предпринимательского сообщества, институтов гражданского общества по созданию благоприятных условий для развития и применения достижений науки и технологии в интересах социально-экономического развития России. И если драйверами технологического развития нашей страны определяются ключевые вузы и научные организации, то с учетом запроса на новую институциональную среду драйвером технологического развития точнее будет назвать концепцию современных кампусов.

Impacto de la prótesis craneal polimérica con ventana acústica y la imagen de ultrasonido funcional en la atención del trauma craneoencefálico
Authors: Hernandez-Paez David A.
Published: October 2024

Con el tiempo, se han desarrollado varios métodos de neuroimagen para abordar el diagnóstico, monitoreo, tratamiento e investigación del cerebro; sin embargo, existe una brecha en términos de sensibilidad, área de cobertura, invasividad y movilidad del participante durante la neuroimagen. La resonancia magnética funcional (fMRI, según sus siglas en inglés), por ejemplo, proporciona un análisis en alta resolución de toda la función cerebral, pero requiere que el sujeto permanezca inmóvil. Esta limitación restringe el estudio de la funcionalidad cerebral durante actividades cotidianas. Además, la fMRI no es un método barato ni portátil. Por otra parte, la electroencefalografía (EEG) en cuero cabelludo permite el movimiento del paciente durante la evaluación, pero no capta la actividad cerebral profunda, mientras que la EEG intracraneal sí aborda esta limitación, pero es invasiva y se reserva para casos especiales donde los beneficios superan los riesgos.

Authors: Anderson Carolina , Lee Sang-A , Mendonca Flavio , Misra Shlok , Byrnes Ken
Published: October 2024

As flight training organizations expand and adapt to meet the growing demands of the industry, organizational leadership and safety departments are continuing to intensively focus on aviation safety and quality assurance through the core values of safety promotion, culture, and education. A flight school’s safety culture, shaped by students’ risk perceptions, can predict safety behaviors. Understanding students’ trust and confidence in this safety culture could potentially aid in early risk mitigation strategies. The purpose of this study was to investigate flight students’ perceived safety culture at a Title 14 Code of Federal Regulations (CFR) Part 141 flight training school in the Southeast region of the United States. The survey was adapted from the Safety Culture Indicator Scale Measurement System. Quantitative and qualitative data were obtained from 398 students. Confirmatory factor analysis and structural equation modeling were used to test structural relationships among organizational commitment, operations interactions, formal safety indicators, and safety behaviors. Results indicated a good model fit to analyze the nine hypotheses. Two of the nine hypotheses were supported. Safety Values and Safety Personnel significantly influence perceived personal risk. The textual data analysis revealed strong student’s opinions towards a medical grounding and no-show procedure initiated by the Flight Department. Additionally, themes identified students’ desire to receive more communication of safety information and the language barriers present in a multi-cultural operation.
Re-Imagining STEM-Based Aviation Education Through Alternative Knowledge Creation
Authors: Morrison Shannon McLoughlin
Published: October 2024

Boeing's workforce study suggests that the aviation industry is going to need over two million more people in the role of pilots, technicians, and cabin crew. Yet, according to the Federal Aviation Administration Civil Airmen Statistics, the number of women who hold the certificate required to fly for a major airline is still just above 4%. These two challenges, a potential shortage in individuals pursuing aviation careers and an industry that struggles to attract and retain underrepresented individuals, have the potential to be addressed if we re-imagine collegiate aviation education. This peer-reviewed practice article leverages a case study performed by Morrison and McNair (2023) to suggest new pedagogical strategies that would support the recruitment and retention of minoritized students to the industry. This analysis of the case study is supported by existing research into why the aviation industry continues to struggle to become more socially just and equitable and how collegiate aviation education is positioned to respond to that struggle.

Published: October 2024

W pracy przedstawiono na podstawie danych GUS zmiany w produkcji buraka cukrowego w województwie kujawsko-pomorskim w latach 2002–2011. W tym okresie powierzchnia uprawy buraka cukrowego zmniejszyła się o 30,3%, plony zwiększyły się o 7,5%, a zbiory zmalały o16,2%. Od 2002 roku do 2010 roku areał buraka cukrowego najbardziej został ograniczony w powiatach: świeckim (o 57,4%) i żnińskim (o 44,9%). W 2002 roku w 25 gminach o największej powierzchni uprawy buraka cukrowego roślina ta zajmowała 26,4 tys. ha (48,8% areału w województwie). Do 2010 roku powierzchnia uprawy w analizowanych gminach zmniejszyła się o 25,2% (do 19,7 tys. ha ) w stosunku do 2002 roku (51,3% areału buraka cukrowego w całym województwie). Głównym powodem ograniczenia produkcji buraka cukrowego była reforma rynku cukru w Unii Europejskiej w latach 2006–2009.

Published: October 2024

This study investigates the optimization of Earth-Air Tunnel Heat Exchanger
(EATHE) systems for maximizing air temperature reduction in Algeria's
Timimoun region. Employing a Response Surface Methodology approach and Ansys
Fluent 16.2 software, we meticulously analyze the influence of critical
parameters on air temperature reduction: pipe depth, length, air velocity,
and thermal conductivity of PVC and high-density polyethylene (HDPE) pipes.
twenty-six simulations were conducted to optimize these parameters. The
results reveal a significant influence of all investigated factors on air
temperature reduction. Pipe depth emerged as the most influential factor,
accounting for (56.22 %) of the temperature variance. This was followed by
pipe length (28.26 %), air velocity (4.88 %), and pipe thermal conductivity
(4.21 %). Based on these findings, we recommend prioritizing deeper
placements (4 m), longer pipes (18 to 20 m), and air velocities below 3
m/s. For moderate-temperature applications, HDPE pipes offer a favorable
choice.

Structural engineers, in particular, face the ongoing challenge of ensuring
the durability and safety of critical infrastructure components, such as
composite beams in bridges and buildings. With aging infrastructure and
increasing demands for sustainability and longevity, innovative solutions
are essential. The safety and longevity of structures, such as composite
beams in buildings and bridges, are paramount concerns. As our
infrastructure ages and environmental sustainability becomes increasingly
important, innovation in materials and methods is crucial. In this context,
we explore a transformative solution the development of advanced
crack-filling materials. These materials hold the promise of revolutionizing
civil engineering by addressing structural challenges and extending the
lifespan of critical infrastructure components. This exploration will delve
into the significance of infrastructure, the challenges faced by structural
engineers, and the potential impact of advanced crack-filling materials on
the field. In this paper we are highlighting the development of a crack
filling material for the composite section using Multi Walled Carbon
Nanotubes (MWCNTs) and Car-bon fibers (CFs). The use of these two nano
materials will subsequently be able to reduce the cracks and heal the
composite section wherever necessary. The flexural strength of the beams is
significantly increased 15% by the addition of MWCNTs and 67% by the
addition of MWCNTs and CFs. The cracked MWCNTs beam coated with MWCNTs,
epoxy, CFs gained strength and failed at 1100 N. This is because the coating
helped to distribute the load across the crack and prevented the crack from
propagating further. The cracked carbon fibers beams coated with MWCNTs,
Epoxy and CFs gained strength and failed at 1760 N. This is because the
MWCNTs + CFs helped to bridge the crack and transfer the load across the
crack. Cement mortar with MWCNTs + CFs after coating increased by 400% This
suggests that the coating is effective at restoring the strength of the
cracked beams.

Published: October 2024

Pesticides have an important role in agriculture since they can prevent large
crop losses which is crucial in order to keep pace with population growth
that is estimated to be 9.7 billion people by the year 2050. The use of
pesticides is not always in accordance with good agricultural practice so
the human and environmental exposure to pesticides are a continuing concern.
Some triazine derivatives are well-known commercially available pesticides
with proven activity. The researchers have task to design and develop new
pesticides with diminished negative influence on environment and humans
together with a good crop protection ability. In order to achieve this, many
computational and artificial intelligence tools have been used along with
extensive experimental work. A group of twenty-one 6-chloro-1,3,5-triazine
derivatives was investigated in the domain of bioconcentration factor, as an
indicator of the bioaccumulation potential of a substance, and multiple
linear regression (MLR)- quantitative structure-property relationship (QSPR)
modeling was conducted. The proposed MLR-QSPR model was extensively
statistically validated in order to provide reliable model for further
re-search work. All conducted procedures, internal and external validation
as well as normality test of residuals indicated good fitness, absence of
systematic error in model development and high predictive ability of the
proposed model.
Purification of amorphous boron powder by using the soluble transformation of acid-insoluble boron magnesium compounds
Authors: Lv S.-X. , Cao Z. , Wu J.-J.
Published: October 2024

At present, amorphous boron powder is considered to be the best fuel for solid fuel-rich propellants due to its extremely high volume calorific value and mass calorific value. Amorphous boron powder produced by magnesium thermal reduction contains many impurities that are insoluble in acids as well as defects such as low purity, excessive particle size, and poor chemical activity, which seriously hinder its large-scale application in the military and aerospace fields. In this paper, the soluble transformation mechanism of insoluble boron magnesium compounds into amorphous boron powder during calcination and a method for purification boron powder were studied. In order to remove insoluble boron magnesium compounds in amorphous boron powder, the insoluble impurities Mg5B2O5 and MgB4 were converted into soluble MgB4O7 and MgO during calcination. The samples were then subjected to either water leaching or acid leaching to convert the crude amorphous boron powder products into high-purity amorphous boron powder products. SEM-EDS, XRD, XPS, and other techniques were used to determine the occurrence states of the impurity phases. The transformation of impurity phases after calcining water leaching and acid leaching was monitored. The results showed that the magnesium content in the amorphous boron powder was reduced to 0.96%, and the purity of the boron powder was increased to 97.34% by subjecting the amorphous boron powder to a combined calcination technique and either water leaching or acid leaching treatment.
A green approach to recovering lithium and cobalt from spent lithium-ion batteries using dilute HCl solution mixed with H. sabdariffa flower extract as a leaching agent

Published: October 2024

Studies on the recovery of lithium and cobalt from spent lithium-ion batteries have attracted a lot of attention in recent years. For a sustainable battery industry, processes for the recycling of valuable metals from spent batteries have been continuously improved and developed via a ?green? approach. In this work, an effective process for the recycling of lithium and cobalt from spent cell phone lithium batteries was investigated using HCl solution at low concentrations in combination with H. sabdariffa flower extract. The influence of parameters such as the concentration of the extract and HCl, pulp density, reaction temperature, and time on the percentage of leached metals was investigated. In these leaching systems, the extract, which contains organic compounds, acts as a complexing and reductive agent for dissolved metals. The optimum conditions for the leaching of these metals were 90% (v/v) of extract, 0.5 mol/L HCl, 10 g/L pulp density, 90oC, and 2.0 hours. 100% Li(I) and 91.3% Co(II) were leached under the optimum leaching conditions. Li(I) and Co(II) from the leachate were completely separated by the use of AG?50W-X4 resins and the presence of the extract in the leach solution had little effect on the recovery capacity for these metals. The metal loading capacity of the resin was determined to be 37.4 mg/g Co(II) and 1.2 mg/g Li(I). Thus, the use of plant extracts such as the flower of H. sabdariffa can be considered as a promising agent for the recovery of valuable metals from spent batteries.
Enhanced microstructural and mechanical properties of Alumix 13 matrix hybrid composites reinforced with B4C and SiC
Authors: Taşcı Ufuk
Published: October 2024

This study produced B4C and SiC reinforced hybrid/composite samples using
powder metallurgy with pre-alloyed Alumix 13 matrix (Al-4.5% Cu-0.5%
Mg-0.05% Si). B4C and SiC were added at 5% by weight and mixed in a
two-dimensional ball mill for 60 minutes to ensure homogeneous distribution.
The mixed powders were compressed at 700 MPa and sintered at 575?C for 60
min. Hardness values were compared with the highest in samples containing 5%
hybrid composite materials. Microstructural characterization of B4C and SiC
particles in the Alumix 13 matrix was performed. Alumix 13 matrix was chosen
for its favorable mechanical properties and compatibility with reinforcement
particles. Ball milling ensured adequate mixing for uniform dispersion while
pressing at 700 MPa created dense samples necessary for successful
sintering. Hardness analysis showed a significant improvement with 5%
hybrid, and microstructural investigation provided information on particle
distribution and bonding quality. This work demonstrates the potential of
B4C and SiC-reinforced Alumix 13-based hybrid/composites for applications
requiring enhanced hardness. It provides valuable data for future research
in powder metallurgy and hybrid composite manufacturing.

The result demonstrates that 1) Technology has significant role in assisting learners to follow the subject and they have varied positive perspectives toward its use in e-learning activity, 2) even though students perceived many OAs were challenging, but through WAG application, it was effective in improving their writing skill.
CLASS CONFLICT AND CHANCE IN THOMAS HARDY’S TESS OF THE D’URBERVILLES: A MARXIST INTERPRETATION
Authors: Shihab Md. Nuruddin Pier
Published: October 2024

This study sets a Marxist lens to explore class conflict and the interplay of fate in Thomas Hardy’s Tess of the d’Urbervilles. The paper examines Tess’s representation as a victim of the Victorian class system and sexual oppression, investigating whether her tragic downfall results from chance or her subordinate social position. The evolving social statuses of central characters like Tess, Angel, and Alec add various dimensions to the narrative tension of the book. By utilizing the qualitative-descriptive method and Marxist concepts of class conflict and capitalism, the analysis accentuates how economic stability, or the lack thereof, intricately influences personal lives and relationships in Victorian society. Tess exemplifies the oppressed working class, while oppressors like Alec and Angel exercise their predatory dominance over her. Moreover, the research article aims to highlight the pivotal role of fate and chance in shaping Tess’s destiny, with coincidences and unexpected events intensifying her misfortunes. Ultimately, the research paper posits that economic fragility not only subjugates the working class but can also precipitate the downfall of the oppressors themselves.
Integrating sustainability in the economics curriculum: Challenges and impact on future decision-makers
Authors: Noguera-Méndez Pedro , Molera Lourdes , Semitiel-García María
Published: October 2024

Research background: Scientific evidence has shown the impact of environmental degradation on human well-being, demanding that political and economic decision-makers address the challenge of reversing this process. In this context, the economic education provided to future policymakers and business managers is crucial, because it can accelerate or impede the transition towards sustainability. What is taught in university economic courses, particularly introductory ones, shapes the ideas and the worldview of economic agents, influencing the decisions they will take in their professional activities.
Purpose of the article: The main objective of this paper is to determine how sustainability is addressed in introductory economics courses, where the foundations of the discipline are laid. Specifically, the goal is to uncover what ideas are conveyed about sustainability in these courses, how they are taught, and whether there have been any changes in the last decades.
Methods: Text Mining and Reflexive Thematic Analysis are applied to examine data from university syllabi and the most commonly used economic textbooks through the lens of a deconstruction of the complex concept of sustainability.
Findings & value added: The main contribution of this paper is a proposal for a deconstruction of the complex concept of sustainability that guides the empirical analysis. The results reveal that sustainability is practically absent from introductory economics courses; notably, no progress has been made on ethical issues or in addressing the impact of nature and environmental degradation on human well-being. Moreover, certain conceptions and models that work against the understanding of sustainability are conveyed in the most used textbooks. Although the role of economics discipline in understanding sustainability and in designing and implementing policies for an equitable sustainable transition is key, the teaching of economics offers resistance to change, remaining part of the problem of unsustainability. The integration of sustainability into the university economic courses still represents a major challenge with implications for future decision-makers.

Published: October 2024

Research background: Over the last ten years, a substantial amount of scholarly research has delved into energy communities (ECs) from diverse viewpoints. These ECs are extremely important in setting the pathway to a clean energy transition.
Purpose of the article: Our objective is to glean valuable insights from publications indexed in the Web of Science (WoS) database to deepen our comprehension of ECs and their academic discourse.
Methods: Data analytics, factorial analysis, and more complex natural language processing (NLP) techniques such as latent Dirichlet allocation (LDA) are implemented to extract valuable insights from over 1000 WoS publications relevant in the EC field. The primary contribution of this study lies in furnishing details regarding the key contributors to the EC scholarly landscape, including authors, their affiliations, universities, and countries of origin. Additionally, we aim to elucidate the prevalent keywords and thematic approaches employed in their research endeavors.
Findings & value added: Considering the extracted dataset, an annual growth rate of 21.15% has been recorded, highlighting the research community’s interest in the field of ECs. Furthermore, three topics are optimally obtained. Overall, a coherence score of 0.44 suggests that the LDA model performs adequately in terms of topic interpretation. Topic 1 relates to community-based energy initiatives. Topic 2, featuring terms like “grid,” “study” and “EU” alongside “energy” and “community,” suggests a focus on energy systems. Topic 3 includes terms such as “generation,” “analysis” and “consumption,” indicating a topic that is centered around the technical or analytical aspects of energy production and usage. This study underscores how the alignment between state laws and EU directives in supporting ECs can serve as a model for other regions. The findings suggest that similar policy frameworks could be effectively adapted to different national contexts, providing valuable insights for countries looking to enhance their renewable energy strategies.

The results of experimental feeding of juvenile rainbow trout in a cage farm using mixed feeds with full and partial replacement of fish oil, incorporating an alternative protein source – barohydrothermally treated (BHTO) white lupine seeds are presented. Based on the results of the experiment, it was found that the use of the tra-ditional source of lipids – fish oil in the compound feed for trout led to a significant increase in the final weight (582 g) of fish, as well as a decrease in the feed conversion ratio (1.21). The second experimental formulation also had a positive effect on the growth rate of rainbow trout, increasing the absolute growth rate by 20%. Clinical examination and control dissection showed that all experimental individuals exhibited no pathological disorders and had high marketable qualities. In both experimental groups, a significant increase in the indicators of protein metabolism in blood serum was revealed (total protein up to 54.7 g/L). In the first experimental group, a reliable decrease in the relative number of monocytes and basophils was recorded. Calculation of economic efficiency showed that the experimental formulation with the inclusion of protein and fatty acid sources in the form of white lupine and flaxseed oil is more cost-effective (at a cost of 161.32 rubles/kg) compared to feeds with fish oil only, as well as feeds using rapeseed oil and fish oil. The presented data indicate that the investigated feed formulations can be used in the industrial cultivation of rainbow trout without loss of nutrient characteristics of feed, fish-biological parameters, and meat quality.

In Russia, in order to transition to highly productive and environmentally friendly agro- and aquatic farming, to create safe and high-quality, including functional, food products, it is necessary to focus on the introduction of new facilities available to consumers into aquaculture. The relevance of the chosen direction lies in the intro-duction of the Don fish into aquaculture in the Southern Federal District and the southern regions of the Russian Federation. Global aquaculture is actively developing. The volume of industrial fishing products in 2023 amounted to 89.6 million tons. At the same time, in recent years, fish catches ranged from 110 to 590 tons, and the average annual production in the Azov-Don region reached 270 tons. Catches are decreasing annually, which leads to the need to increase the production of aquaculture facilities. The main objectives of the research are to develop the design of a plant for growing Don fish (Vimba vimba) and conduct research on the content of producers. Experiments have been carried out on the cultivation of young Don fish on granular feed in an upgraded installation. The experiments were carried out in two versions: on water from an open source of water supply prepared using a water treatment unit, and on tap water. Conducting weekly hydrochemical analyses of water and biological material in experimental installations for the maintenance of producers and the rearing of juveniles made it possible to determine the optimal indicators for the maintenance of producers, spawning, holding and rearing of larvae.
Transportation of fish oil through a pipeline by a single-screw pump

Published: October 2024

Fish oil is processed from pelagic fatty fish species, in humans they are sources of fatty acids, especially omega-3. Fish oil differs in the composition of fatty acids. New sources of fish or fish oil are being studied. Increasing the efficiency of technological lines is associated with improving the interoperative transportation of fish oil. Manufacturers of processing lines use single-screw pumps for transporting fish oil. Single-screw pumps are advantageous for pumping highly viscous media and have a relatively low cost. The purpose of the article is to adapt to fish oil a method for calculating a continuous fish oil supply system, taking into account the characteristics of a process pipeline, a single-screw pump and rheological parameters of fish oil. The results of the analysis of the performance characteristics of single-screw pumps and the results of experimental work are used. The Buckingham-Rayner equation was used in calculating friction losses in the pipeline, as well as the modified Reynolds number. The flow rate, power, and the effect on them of the viscosity of the liquid for the Atlas W63-1B pump at different rotor speeds are estimated. As the frequency increases, the pressure at constant flow or the flow at constant pressure increases. Examples of determining the hydraulic and energy parameters of pumping systems when pumping fish oil are given. As the viscosity increases, the productivity decreases significantly, and the power consumed increases. As the diameter decreases, the hydraulic resistance of the pipeline increases. The presented algorithm for calculating the movement of fish oil in pipeline systems makes it possible to rationalize pumping systems, create energy-efficient technologies for working with fish oil, and ensure a scientifically sound pump choice.
Pre-medical assistance in the health care system and its relationship with related categories

Medical care is one of the basic categories of medical law. The legislation interprets it as the activity of professionally trained medical workers, aimed at prevention, diagnosis and treatment in connection with diseases, injuries, poisoning and pathological conditions, as well as in connection with pregnancy and childbirth. It is aimed at ensuring the implementation of the constitutional human right to health care. However, health care in critical situations can be provided by providing other types of care: pre-medical and emergency. Interest in the latter especially increased during the war, when urgent human conditions began to occur much more often, and the number of people capable of providing medical assistance decreased. In practice, there are ambiguous interpretations of the category «pre-medical care» and concepts related to it, and therefore the legal regulation of the provision of pre-medical care needs improvement. The term «emergency care» is not used by legislation, but its content is analyzed in the article to characterize a set of actions aimed at overcoming emergency conditions, which are provided by people who do not have the education necessary to provide medical and paramedical care. Three criteria are proposed for comparing medical, pre-medical and emergency care: 1) the grounds (conditions for providing care), 2) the amount of care provided, and 3) entities authorized to provide medical, pre-medical and emergency care. Thanks to these criteria, common features in these types of pre-medical care, as well as differences between them, have been established. A complex of shortcomings in the legal regulation of providing pre-medical care was identified, the main of which are related to the problem of establishing the circle of persons who have the right and obligation to provide pre-medical care. The issue of the legality of carrying out medical manipulations on victims who are in an emergency condition by persons who have the right to provide only emergency aid is raised.
Legislative regulation of the organization and conduct of gambling: current issues and solutions
Authors: Bodrov Y.
Published: October 2024

The article is dedicated to highlighting current issues in the legislative regulation of the organization and conduct of gambling in Ukraine, as well as finding optimal solutions to these problems. Based on the conducted analysis, it is stated that the legislative regulation of public relations in the field of gambling is characterized by a wide range of issues, including deficiencies in the conceptual and categorical apparatus, insufficiently clear general requirements for gambling organizers, and the absence of requirements aimed at ensuring the stable operation of gambling establishments under conditions of unstable power supply.
Directions for improving the conceptual and categorical apparatus of Ukrainian gambling legislation are outlined. The author formulates a definition of the term «gambling.» The types of gambling are systematized, the shortcomings of their legislative description are identified, and the necessity of legally defining lotteries as a type of gambling is substantiated.
It is concluded that the general requirements for the subjects organizing and conducting gambling are insufficiently coordinated, particularly the requirements regarding their impeccable business reputation. It is proposed to establish a licensing requirement for the impeccable business reputation of legal entities intending to conduct business activities in the field of gambling.
The article pays special attention to the problem of ensuring the uninterrupted functioning of gambling establishments under conditions of constant stabilization and emergency power outages. It is emphasized that during such outages, the operation of electronic and technical equipment in casinos and gaming halls is significantly disrupted, making it impossible to record the current state and results of games, fairly calculate winnings, and monitor draws online. In this regard, it is proposed to establish a legislative requirement for the mandatory equipping of casino and gaming hall establishments with backup power sources.
To improve the administrative and legal foundations of the organization and conduct of gambling, the article proposes a comprehensive review of sectoral legislation to ensure its consistency, completeness of regulation, adequacy to modern realities, and compliance with the main trends of gambling development.
