Multilingualism in Lithuanian Children’s Folklore
Authors: Anglickienė Laimutė , Macijauskaitė-Bonda Jurgita
Published: December 2024

Multilingualism and multiculturalism have always been phenomena present in folklore. Since the last decades of the 20th century, due to changes in lifestyle influenced by factors such as globalization, intense migration, development of social media, and information technologies, manifestations of multilingualism and multiculturalism have become even more noticeable and, in consequence, are becoming an important feature of contemporary folkloric creation. Focusing on a few genres, namely, counting-out rhymes, games, horror stories and horror verses, this article presents and discusses manifestations of multilingualism in Lithuanian children’s folklore. The following are the main research questions that the present study aims to investigate: How does multilingualism manifest in children’s folklore and what functions does it perform? How do children adopt and transmit folklore, i.e. how do they adopt and creatively reinterpret texts and plots, namely, forms and contents from other languages? Which foreign languages have major impact on Lithuanian children’s folklore? The methodology of the research consists of analytical descriptive and comparative analyses. The research has shown that Lithuanian children’s folklore is dynamic and open to other languages and cultures. Children are attracted by linguistic play and feel comfortable with texts containing foreign or unknown words. In Lithuanian folklore, two major influences can be traced: Russian influence, particularly from World War II until the beginning of the 21st century, and influence from English-speaking countries, beginning in the 1990s and continuing to the present. Children translate folklore, sometimes word for word, adapt foreign texts, plots, traditions, take over certain genres, or integrate separate words or phrases from other languages into Lithuanian folklore.
Just Dance? The Economic Effects of the Ultra Europe Music Festival in Split
Authors: Žilić Ivan
Published: December 2024

This paper identifies the economic impacts of the Ultra Europe Music Festival, a popular electronic music festival taking place in the city of Split. Using publicly available daily tax data on fiscalised amounts and the number of receipts, we examine the festival’s effects on taxable consumption of accommodation, food and drink services, retail, and taxi services. To isolate the causal effects, we employ two-way difference-in-difference and two-way event study on a daily frequency and county level, with other Dalmatian Adriatic counties as controls. Results reveal temporary positive effects on the consumption of food and drink services, taxi services, and, to a lesser extent, retail. However, no significant impact on accommodation is recorded, arguably due to the prevalence of non-fiscalised accommodation in private households. The positive effects on taxable dimensions of consumption are concentrated on festival days, with spillover effects present on the day following the event.
Structural Decomposition of the Economic Growth in the Croatian Economy
Authors: Mikulić Davor
Published: December 2024

Croatia has been falling behind more successful new member states and belongs to the group of the least developed EU economies. After joining the EU, the availability of European structural funds, the removal of all trade barriers, and the strong growth of the tourism sector resulted in accelerating growth rates. This paper aims to decompose the total economic growth in the Croatian economy in the 2010-2018 period into the effect of increasing demand and technology improvements. The study is based on the structural decomposition analysis, which is the extension of the input-output model and has been widely used in previous studies in many economies to identify the driving forces of economic growth over a certain period. Based on empirical results, it can be concluded that the total final demand effects related to the increase in the total expenditures on the total economy level have been three times more intensive than the effects of technological change. It is estimated that the increase in final demand positively affected economic activity in each sector, while the distribution of technological change effects significantly varies. The highest positive impacts of technological change are found in the manufacturing, agri-food, and hospitality sectors. On the other hand, adverse effects of technological change are found in energy products, trade and transport, and various personal and business services. Significant variations are found in the growth dynamics of manufacturing sectors. The highest cumulative growth in 2010-2018 has been recorded in the production of computers and electronics, furniture, machinery and equipment, and wood products. In the case of computers, machinery, and furniture, the main effects are related to the product mix effects. At the same time, the economic growth of the wood industry is primarily the result of technological effects and increased participation in the supply chain of other industries.

Authors: Zuo Hao , Teng Yun , Chen Zhe
Published: December 2024

Renewable energy coupling hydrogen production technology can overcome the weakness of randomness and intermittence for renewable energy to a certain extent. However, due to the long-distance and reverse distribution of renewable energy generating units and the main network, there will be a risk of oscillation instability when a high proportion of power electronic hydrogen production system is interconnected with the power grid. Firstly, the impedance model of the electric hydrogen production system is established. The oscillation characteristics of hydrogen production system interconnected with power grid are analyzed. Secondly, the influence of electrolytic hydrogen system on the stability of multi-energy system is analyzed. The instability problems caused by input power fluctuation and hydrogen production rate change are studied. Then, an oscillation suppression strategy for renewable energy hydrogen production system based on power allocation is proposed. It is used to enhance the stability of the multi-energy system of the electrolytic water hydrogen production system. Finally, through the establishment of renewable energy electrolysis hydrogen experimental simulation system. The system frequency stability under different renewable energy output fluctuations and different impedance conditions of the system is verified. The simulation results show that the proposed multi-energy hydrogen production control method based on power allocation can ensure the stability of the system under the fluctuation of renewable energy output.

Drought stress is an unavoidable factor that exists in a variety of habitats which hinders the production, quality, and energy of plant biomass. Drought conditions result in oxidative stress in plants due to excessive reactive oxygen species (ROS) produced as a result of low CO2 which interferes with plant photosynthetic capacity. Consequently, during periods of drought stress, the transport of nutrients and the mass flow of water-soluble nutrients like nitrate, sulfate, calcium, and silicon is reduced. The application of traditional approaches in developing drought-tolerant crops is a time-consuming process, and the use of advanced biotechnology for agricultural development is still viewed with caution. The use of plant growth-promoting rhizobacteria (PGPR) as a cost-effective and environment friendly strategy can be adopted to enhance crop development in drought stress conditions. The synthesis of 1-aminocyclopropane-1-carboxylate (ACC) deaminase promotes plant nutrient uptake by metabolizing plant ACC, consequently preventing the accumulation of ethylene. The PGPR enhances the plant's defense mechanisms, leading to higher relative water content, decreased oxidation products and increased levels of antioxidants and osmo protectants within the plants. The synthesis of exopolysaccharides (EPS) also improves the soil's capacity to retain water. Osmolyte synthesis is increased by PGPR and effectively mitigates ROS's harmful effects to assist the plant growth. For the manufacture of bio-fertilizers to minimize the negative impacts of drought stress on crops grown in dry environments, multifaceted PGPR are promising options. This review outlines potential future directions for sustainable agricultural production and suggests techniques to improve their effectiveness as bio-inoculants in field settings.
The Role of Historical Sources for Identification of Early Photography
Authors: Avetyan Natalia Yu.
Published: December 2024

The last three decades have been marked by a surge of interest in 19th century photography, which has made it a full-fledged participant of the art market and, more importantly, the subject of research activities of a wide range of specialists: cultural historians, philosophers, art historians, restorers, chemists and physicists. By setting different goals and using the scientific tools of their field of knowledge, they contribute to the understanding and preservation of photography as one of the key components of the historical memory of mankind. To date, Russian scholars have introduced a significant number of new works of early photography into the scientific turnover. The close interest to daguerreotypes from collectors, which led to the increase in prices on the antique market, was largely due to a number of scientific studies, which found expression in publications and the organisation of exhibitions.

The present article is devoted to current issues of research practice involving the study, attribution and conservation of photography as a material object. These processes are among the primary tasks of specialists working with arrays of photographic materials of different historical and cultural significance in museums, archives and libraries. The importance of the development and testing of new methods of studying monuments within the framework of the formation of the domestic experience of studying photography is noted.

For the first time, the question of the reliability of the approach, due to which written testimonies act as the main sources in the attribution of a monument is raised: often used as a starting point of expertise, they may later (in a comprehensive study) contradict the data of other scientific methods. As a result of the study, contradictions between written historical evidence (textual information) and the data of a complex scientific analysis of early Russian photography have been revealed; a comprehensive methodology for its attribution by museum specialists has been proposed.
Commemorative Narratives in the Interpretation of Folk Culture
Authors: Nikiforova Sargylana V.
Published: December 2024

S.A. Zverev (1900—1973), a storyteller, a connoisseur of traditions and a promoter of Yakut culture, is used as an example of his work to examine the forms of preserving authentic forms of folk art and reconstructing ethnic performing specifics. On the border of Nyurba and Suntar there are places connected with the history of his family, here he was brought up, his talent was recognised for the first time and his creative activity began. The influence of the above on his creative work is undeniable, but has not been investigated. The experience of interpreting the interviews of three respondents from the Nyurba district to determine the ethnography of space and places of memory in the authentic forms of folk culture, the keeper, initiator and translator of which was Zverev, is presented. Some provisions of the theory of social production of space, as well as the theory of memory place, considered as a symbolic tool connected with the reality of the past and as a source of meanings, are used. The research methods can be applied as a conceptual basis in solving private and fundamental problems of regional culturology, art history, in the reconstruction of folk music, dance art, etc. The substantiation of the impact of cultural memory on the formation of ethnic identity in the mode of anniversary commemorative practices is proposed. An example of relations: author – text (establishing the reality of the work) at the stage of cultural transition from non-written to written forms is considered. The article describes and analyses the process of folk dance reconstruction taking into account local ethnic specifics. The prerequisites for the reconstruction of authentic forms of folk art are defined and S.A. Zverev’s personal contribution to the preservation of traditional values is partially described. It is determined that memorial practices in the process of identification construct and permanently edit the ethnos’ representation of itself.

Drought, a persistent natural disaster, poses significant challenges to ecosystems, agriculture, water resources and socio-economic stability worldwide. The evolution of drought forecasting models reflects a continuous pursuit of greater accuracy and lead time, particularly highlighted by events like the 2012 US Midwest drought. Traditional models relying on empirical relationships have faced limitations in capturing the complexities of meteorological droughts, leading to the exploration of AI-driven approaches. This comprehensive review explores the landscape of drought forecasting, focusing on the integration of AI and hybrid models. The advantages of AI, such as its ability to handle nonlinear relationships and vast datasets, have revolutionized drought assessment and prediction.

Various AI techniques including Neural Networks, Support Vector Machines, Fuzzy Logic and Deep Learning, offer unprecedented accuracy and real-time monitoring capabilities. Hybrid models, combining AI with traditional statistical or dynamical approaches, show promise in enhancing predictive capabilities. The integration of Wavelet Transform with Neural Networks and other hybrid strategies has demonstrated success in capturing non-linear relationships and improving prediction accuracy. The future of AI-driven drought forecasting lies in collaborative efforts, innovative research and ethical practices. By navigating these challenges and seizing opportunities, AI models can contribute significantly to building resilience and sustainable management of water resources globally.

В условиях многолетнего стационарного опыта на базе Нижегородского НИИСХ-филиал ФГБНУ ФАНЦ Северо-Востока на светло-серой лесной легкосуглинистой почве изучали эффективность систематического внесения возрастающих доз минеральных удобрений на фоне последействия известкования, проведенного в 1978 г. Результаты наблюдения за динамикой кислотности почвы показали, что длительное применение минеральных удобрений способствует увеличению рН и снижению насыщенности ее основаниями. К 2014 г. гидролитическая кислотность возросла, а сумма поглощенных оснований снизилась. При этом наблюдаемые изменения находятся практически в прямой зависимости от дозы внесения NPK, а последействие известкования исчерпало свои возможности даже по высоким дозам внесения доломитовой муки.

The research conducted in conditions of long-term stationary field trial on basis of the Nizhny Novgorod Research Institute – branch of FSBSO FARC the North-East on light-grey forest light loamy soil. We studied the effectiveness of systematic application of increasing the doses mineral fertilizers on the background of after-effect of liming, performed in 1978. The results of monitoring of soil acidity showed that long-term application of mineral fertilizers increases pH and decreases saturation of soil with bases. To 2014 year, the hydrolytic acidity had increased and the amount of absorbed bases had decreased. At the same time the demonstrated changes are in direct ratio to the doses of NPK. After-effect of liming had exhausted its possibilities even for high doses application of dolomite.

Анализ результатов исследований профильного послойного распределения содержания, запасов общего углерода и азота, соотношения C:N  в многолетних опытах, проводимых на серых лесных и черноземных почвах, показал, что как органические, так и минеральные системы удобрения оказывают существенное положительное воздействие на органическое вещество исследуемых почв. Органические системы удобрения влияют на содержание органического вещества почв больше, поскольку действуют как непосредственно, так и косвенно за счет повышения величины биомассы корнивно-пожнивных остатков и корневых выделений возделываемых культур. Минеральные же системы удобрения влияют на содержание органического вещества только косвенно. Изменялось также распределение органического вещества по слоям профиля. При этом во всех исследуемых почвах сохранялись характерные генетические признаки их типичного органопрофиля.

Analysis of the results of studies of the profile layer-by-layer distribution of the content, stocks of total carbon and nitrogen, the C:N ratio in long-term experiments conducted on gray forest and chernozem soils showed that both organic and mineral fertilizer systems have a significant positive effect on the organic matter of the studied soils. Organic fertilizer systems affect the organic matter content of the soil more, because they act both directly and indirectly by increasing the biomass of the root-crop residues and root excretions of cultivated crops. Mineral fertilizer systems affect the content of organic matter only indirectly. The distribution of organic matter in the layers of the profile also changed. But at the same time, all the studied soils preserved the characteristic genetic characteristics of their typical organoprofile.

Изучено влияние минеральных удобрений на содержание обменного калия в почве, калийный статус и продуктивность колонновидной яблони. Опыты проводились в экспериментальном саду, расположенном в лесостепной зоне Среднерусской возвышенности (Орловская обл.). Почва сада - агросерая среднесуглинистая, имеющая среднекислую реакцию и высокое содержание органического вещества. Плодовые насаждения представлены деревьями колонновидной яблони сортов Поэзия и Приокское на подвое 62-396. В качестве удобрений использовали мочевину (NH)CO и сульфат калия (KSO) в дозах NK, NK, NK , которые вносили ежегодно весной. Содержание обменного калия в почве определяли послойно (0-20 и 20-40 см). Калийные удобрения способствовали увеличению концентрации обменного калия в почве в слоях 0-20 см (62-89%) и 20-40 см (37-44%). Количество калия в листьях и плодах также возрастало. Однако концентрация калия в листьях (0,77-0,96% сух. в-ва) оставалась значительно ниже оптимальной (1,5% сух. в-ва). Существенных различий по урожайности между вариантами опыта не выявлено. Применение удобрений в дозах NK и NK привело к увеличению средней массы плода сорта Поэзия на 16,3%.

The influence of mineral fertilizers on the content of exchangeable potassium in the soil, potash status and productivity of columnar apple trees has been studied. The experiments were conducted in the experimental orchard located in the forest-steppe zone of the Central Russian Upland (Orel region). The soil of the orchard was agro-gray medium loamy having a medium acid reaction and a high content of organic matter. Fruit plantations were represented by columnar apple trees of the Poesia and Priokskoye cultivars on the rootstock 62-396. Urea ((NH)2CO) and potassium sulfate (KSO) were used as fertilizers in doses NK; NK; NKthatwere applied annually in spring. The content of exchangeable potassium in the soil was determined in layers (0-20cm and 20-40cm). Potash fertilizers contributed to an increase in the concentration of exchangeable potassium in the soil both in the 0-20 cm layer (62-89%) and in the 20-40 cm layer (37-44%). The amount of potassium in the leaves and fruits also increased. However, the potassium concentration in the leaves (0.77...0.96% of dry matter) remained significantly below the optimal concentration (1.5% of dry matter). There were no significant differences in yield between the variants of the experiment. The use of fertilizers in doses of NKand NK led to an increase in the average fruit weight of Poesia.

Изучено влияние технологии прямого посева на основные показатели плодородия почвы на чернозёмах южных Центрального Предкавказья. Проведены обобщение и статистическая обработка данных мониторинга плодородия земель сельскохозяйственного назначения при возделывании по традиционной системе обработки почвы в период с 1998 по 2007 г. и после перехода на прямой посев с 2008 по 2018 г. Установлено, что переход на прямой посев положительно сказался на содержании органического вещества и подвижного фосфора. Сравнительный анализ периодов показал, что содержание органического вещества увеличилось с 2,7 до 3,5%. Содержание подвижного фосфора увеличилось с 12 до 16 мг/кг, площадь пашни со средним содержанием данного элемента питания выросла с 15 до 32%, а 4% пашни перешли в группу с повышенным содержанием. Увеличение подвижного фосфора связано с его накоплением в слое почвы 0-10 см при прямом посеве. Достоверного и прослеживаемого влияния способа обработки почвы на pH за период наблюдений не установлено. Содержание обменного калия продемонстрировало сначала рост с 358 до 395 мг/кг, а затем снижение до 336 мг/кг.

The influence of direct seeding technology on the main indicators of soil fertility in the chernozems of the southern Central Caucasus has been studied. Generalization and statistical processing of data on monitoring the fertility of agricultural lands under cultivation according to the traditional tillage system in the period from 1998 to 2007 and after the transition to direct sowing from 2008 to 2018 were carried out. It was found that the transition to direct sowing had a positive effect on the content of organic matter and mobile phosphorus. A comparative analysis of the periods showed that the content of organic matter increased from 2.7 to 3.5%. The content of mobile phosphorus increased from 12 to 16 mg/kg, the area of arable land with an average content of this food element increased from 15 to 32%, and 4% of arable land moved to the group with an increased content. The increase in mobile phosphorus is associated with its accumulation in the soil layer of 0-10 cm during direct sowing. No reliable and traceable effect of the tillage method on the pH during the observation period has been established. The content of exchangeable potassium first showed an increase from 358 to 395 mg/kg, and then a decrease to 336 mg/kg.

Динамику обменных и водорастворимых соединений калия в агросерой почве вишневого сада изучали в течение 6 лет (2017-2022 г.). Основными факторами, повлиявшими на калийный режим, были: обеспеченность почвы калием, метеорологические условия (особенно осадки) и внесение удобрений (сульфат калия в дозах К40-К160). Уровень доступного растениям калия в почве неудобренных участков был стабильным в течение исследуемого периода (160±12 мг/кг), тогда как внесение удобрений привело к накоплению обменного калия в верхнем слое почвы до 260±20 мг/кг. Увеличение запасов обменного калия не повлияло на продуктивность деревьев. Следовательно, удобрение вишневого сада калием в первую декаду после посадки не требуется, если начальный уровень калия в почве составляет 160 мг/кг или выше.

The interannual dynamics of exchangeable and water-soluble potassium compounds in Haplic Luvisolof of sour cherry orchard were studied during 5 years (2017-2022). The main factors affected potassium regime: the supply of soil potassium, meteorological conditions (especially – precipitations) and fertilization by potassium sulfate (doses K40-K160). The level of plant-available potassium in soil of unfertilized plots was stable during the studied period (160±12 mg/kg), but the fertilization led to the gradual accumulation of exchangeable potassium in upper soil layer to the level of 260±20 mg/kg. The increasing of exchange potassium reserves did not affect the productivity of trees. Consequently, the fertilization of sour cherry orchard with potassium in the first decade after planting is unnecessary, when the initial level of soil potassium is 160 mg/kg ore above.
