The use of pyrogenic charcoal (biochar) as a soil amendment in agriculture has ancient origins: it aims to improve soil fertility by changing soil’s chemical and physical properties. Today biochar is further of interest for its long-term carbon fixation effect. Given the high potential of biochar for water and nutrient retention, its use in viticulture may potentially compromise grape and wine quality, since moderate water deficit and limited nitrogen availability are necessary pre-conditions for high quality grape production. The aim of this study was to identify the effects of biochar as a soil amendment on grape and wine quality. The study showed that the addition of biochar pure and biochar enriched with compost in soils did not negatively affect organoleptic properties of the wine. Furthermore, there were no significant differences between volatile organic compounds (VOCs) of wines made from biochar-treated grapes from those of the untreated control. Biochar pure or also moderately enriched with compost as soil amendments did not permanently change nitrogen availability in the soil, nor did they alter the vegetative growth or productivity of the vines. Therefore, the use of biochar in viticulture can be recommended to correct the pH of the soil, increase its water absorption and retention, and for a long-term carbon sequestration, without deleterious effects on growth or productivity, and thus maintaining the quality of the resulting wine.
Design-Driven Translational Tools to Manage Cardiac Regeneration as Applicable to Clinical Practice
Authors: Suchkov Sergey
Published: February 2024

Cardiovascular disease is the leading cause of death, with 80% of cases occurring in developing countries. Innovative therapies are required to reduce mortality and limit or abolish the necessity for cardiac transplantation. Over the last decade, stem cells have been a promise for the cure of several diseases not only due to their plasticity but also to their capacity to act in a paracrine manner and influence the affected tissue. Human SC-based therapy derivatives are extremely attractive for therapeutic development because they have direct pharmacologic utility in clinical applications, unlike any other adult cells. Moreover, stem cell-derived paracrine factors have been shown to suppress inflammation and apoptosis, stimulate angiogenesis, and amplify the proliferation and differentiation of resident cardiac stem cells (CSCs). And SC therapies are thus viable alternatives to conventional treatments with substantial therapeutic potential; market opportunities are huge, as multiple product candidates are expected to be approved over the coming decade.

Authors: Chen Lifeng , Yu Wenwen , Qian Limin
Published: February 2024

Environmental, social and governance (ESG) goes beyond its function as a business to maximize profits for the shareholders to work for societal purposes. Meanwhile, the green credit policy in China is still in its infancy, and the impact of green loans on the efficiency of commercial banks is significantly different. In this context, this paper details the company’s performance in crucial aspects such as low-carbon operations, eco-friendly financial innovation, a sustainable economic system, data security and the development of organizational capabilities to provide a sustainable development paradigm for supply chain finance technology peers. Based on ESG portfolio, we found that adding ESG holdings to a company affects its compliance with delivery or environmental rules, and anode and cathode of ESG combined Dual Carbon (DC) are presented in terms of emission levels. Our further research indicates the implementation of Green Credit Guideline has a positive impact on ESG performance of both green and polluting firms in comparison with others. The result was fully supported by different methods and models including PSM-DID (Propensity Score Matching-Differences-in-Differences), QDID (Quantiles Differences-in-Differences), and Kernel approaches, which can provide more implications and references for policy makers. Investors, politicians, and other essential stakeholders perceive ESG as a strategy to protect enterprises from future risks.
Bending of a five-layered composite beam with consideration of two analytical models
Authors: Magnucki Krzysztof
Published: February 2024

The subject of the work is a five-layered composite beam with clamped ends subjected to a uniformly distributed load along its length. Two analytical models of this beam are developed with consideration of the shear effect. The first model is formulated on the basis of the classical zig-zag theory. Whereas, the second model is developed using an individual nonlinear shear deformation theory with consideration of the classical shear stress formula (called Zhuravsky shear stress). The system of two differential equations of equilibrium for each beam model is obtained based on the principle of stationary total potential energy. These systems of equations are exactly analytically solved. The shear effect function and the maximum deflection are determined for each of these two beam models. Detailed calculations are carried out for exemplary beams of selected dimensionless sizes and material constants. The main goal of the research is to develop two analytical models of this beam, determine the shear effect function, the shear coefficient, and the maximum deflection in the elastic range for each model, as well as to perform a comparative analysis.
Ormiańskie pochodzenie kronikarza lwowskiego Jana Tomasza Józefowicza: mit i rzeczywistość
Authors: Kapral Myron
Published: February 2024

The article discusses the question of the Armenian origin of the Lviv chronicler Jan Tomasz Józefowicz (1662‑1728). The origin of the myth as to the Armenian ancestry of the Lviv chronicler Jan Tomasz Józefowicz dates back to the mid‑19th century. This was concocted by Aleksander Batowski and especially by Sadok Barącz. The latter presented a false Armenian genealogy not only for Józefowicz but also for the Lviv historian Bartłomej Zimorowicz, the poet Szymon Szymonowicz, and other historical figures who had no connection to Armenian families whatsoever. The myth about Józefowicz’s Armenian roots was to persist particularly strongly and even survived until the beginning of the 21st century, appearing in numerous publications. However, these imaginary Armenian origins did not align with his own oral accounts, and the information about Armenian history found in his chronicles. Recent publications and the appearance of municipal legal registers along with the testaments of Lviv citizens into scholarly circulation allow us to confidently state that Józefowicz had Polish origins with elements of German and Italian heritage.
Mefistofeles à rebours. Komentarz do Koszmaru Iwana Karamazowa
Authors: Augustyn Leszek
Published: February 2024

The article is an attempt to formulate a philosophical interpretation of the figure of Ivan Karamazov’s “devil” or to explicate the theoretical and conceptual connotations associated with the demonic motif in Fyodor Dostoyevsky’s novel The Brothers Karamazov. The reasoning follows the line: the author of the novel – the hero of the novel – the figure of the devil. The questions explored in the article are related to the duality of Ivan, a character depicted in the novel (this issue is discussed within a broader anthropological context), to the conceptual and – most importantly – ideological background for “Ivan Karamazov’s nightmare”, to the intellectual and ethical conflicts unfolding in him, and finally to the ambiguous relationship between Christianity and socialism (theological and political contexts).

The article presents two poetic prayers by Valery Bryusov, which constitute a model example of varieties within this literary genre (a pleading prayer, thanksgiving prayer and supplication, the conventional type). Shown is how the Russian poet’s works activate associative meanings (first of all, the connections with the Bible and other cultural texts at the turn of the 20th century), this being the subject of indepth analysis. Emphasised equally was the relational dimension of the poetic prayer.
Інтерпретативні стратегії сучасної української й польської прози в контексті літературознавчої антропології
Authors: Kropyvko Iryna
Published: February 2024

Interpretative strategies are explored as a type of textual strategies alongside narrative and receptive ones. We illustrate modern, prose‑bound interpretative strategies targeting various types of perception and aesthetic delight. The interpretative strategies of modern Ukrainian and Polish prose are affected by the author’s choice of the convention lines implemented in the story, and the types of perception the story is targeting. These parameters help implement the story’s semantic structure, which determines the way it is interpreted by the reader. The reader’s own life, emotional, and receptive experience builds a criterion for the story’s maturity. The reader’s interpretative effort is seen in the text as a game which is divided into separate milestones and requires a shift in the interpretative vector at each of them or implies the reader’s ability to perceive the virtual worlds of the rhizomatic plot that maps a modern person’s mental processes. The ability to notice in one text various interpretative strategies constitutes one of the ways for the reader to take aesthetic delight as well as building within them man‑world interaction skills, the ability to accept the world’s uncertainty, someone else’s different attitude.
Белетризація щоденникового простору у книзі Олега Сенцова Хроніка одного голодування
Authors: Shteinbuk Feliks
Published: February 2024

The main paradox of the book by Oleg Sentsov, the famous Ukrainian filmmaker, is that despite its distinctly documentary basis the text is endowed with obvious qualities of fictionalization. In this regard, the purpose of the article is to identify the fictional firsts in Oleg Sentsov’s book “The chronicle of one hunger strike”, based on cultural, historical, biographical, and hermeneutical methods, and also to analyze these firsts in terms of how they shape the idea and artistic content of this work. As a result, the conclusions were formulated according to which the book under consideration uses various forms of fictionalization of comments, reflections, dreams, memories, and even physiological processes of the human body to fictionalize the diary space through which a real person acquires an artistic dimension, which paradoxically does not undermine their authenticity, but, on the contrary, gives the real person fictional conviction and powerful emotional power and depth.

Authors: Quero Gervilla Enrique Federico , Marynenko Pavlo
Published: February 2024

The translation of onomatopoeic verbs is one of the most difficult and insufficiently examined questions in translation studies. Many authors have tried to establish different translation strategies for onomatopoeias (units closely related to language and culture). While translating this kind of linguistic phenomena, we must study the linguistic mechanisms of the source language too. Actants of onomatopoeic verbs play an important role in the correct choice of an equivalent in the target language. This article analyzes the onomatopoeic verb “плескать” in the Russian language. The purpose of the article is: 1) to describe the meanings of the verb “плескать” in the Russian language and its actants; 2) translation of actions denoted by the verb “плескать” into Spanish. In order to realize this analysis, the examples of contexts employing the verb “плескать” from Russian literature were translated. This analysis permitted us to systematize the parameters necessary to translate the verb “плескать”. Besides it confirmed that the meaning of the verb and its actants are important elements in choosing correctly the translation equivalent.

Published: February 2024

In this paper, we utilize deep learning methods to perform automatic feature learning from multi-source heterogeneous data, mapping different data into the same hidden space, and obtaining the deep features of the data associated with students and sports. A small amount of information is filtered from a large amount of input information by assigning weights in the attention mechanism and higher weights are assigned to it, and a collaborative filtering recommendation algorithm based on deep learning and algorithm evaluation index is proposed. The deep learning algorithm is integrated into the classroom of “basketball one-handed in situ over-the-shoulder shooting” in college B for empirical analysis, and the teaching effect is compared with that of the traditional teaching mode. The results show that the average scores of 50 meters, sit-ups, pull-ups, 800 meters, 1,000 meters, seated forward bending, and cross-direction running of the students in the physical education classroom based on deep learning are higher than those of the students in the traditional physical education classroom by 5.94, 6.83, 7.69, 6.56, 5.87, 5.1, and 3.68 in the physical fitness comparison analysis. Study shows that physical education teaching based on deep learning can improve students’ various physical qualities, which is of great significance and value in accelerating the high-quality development of physical education and promoting students’ comprehensive development.

Authors: Li Qian
Published: February 2024

Today, when quality education is increasingly emphasized, it is necessary to strengthen the strength of dance aesthetics education for students in colleges and universities. This paper establishes a PBL teaching mode for dance aesthetic education based on the PBL teaching method and designs a teaching experiment for this teaching mode. In the PBL teaching process, the optical motion capture system is used to obtain the three-dimensional data of dance movements. After processing the three-dimensional data through data conversion and normalization, the time and channel refinement fusion hypergraph convolutional network is introduced to identify the dance movements, which helps teachers to carry out the teaching of dance movements. The data were quantitatively analyzed for the effects of dance movement recognition, students’ dance skill level, state of mind, and aesthetic awareness on the effectiveness of dance movement recognition and dance aesthetic PBL teaching model. The results showed that the accuracy of the dance movement recognition model in ballet movement recognition reached 89.63%, the dance skill level of students in the experimental class increased by 7.51±0.05 points compared with that of the control class, and their aesthetic sense, aesthetic appreciation, and aesthetic creativity all showed very significant differences at the 1% level. Applying the PBL teaching method to dance teaching and aesthetic education can fully cultivate students’ aesthetic sense and promote the innovative integration of dance aesthetic education in colleges and universities.

Authors: Jin Wei , Du Bo
Published: February 2024

The in-depth integration of big data technology and red cultural resources promotes the integration of red cultural resources into the integrated construction of the Civic and Political Science curriculum. In this paper, we use information gained to extract the text features of red cultural resources, combine TF*IDF to calculate the weights of feature items, represent the text to the vector space model, put forward the automatic classification algorithm of decision tree red cultural resources text, and build the framework system of red cultural resources text classification. Teaching stage and political appearance are used as independent variables, respectively, to explore the differences in the teaching effect of Civics courses at different stages of universities, secondary schools, and elementary schools as well as among CPC members, members of the League, and the people, and focuses on analyzing the utilization rate of the red cultural resources of Civics course teaching as well as the students’ participation degree. The results show that only 0.0537 students think that the school functionaries are not working correctly, and there exist 0.4308 students who believe that the classroom teaching is not innovative enough. Combining red cultural resources and the integrated teaching of Civic and Political Science courses requires more excavation of red cultural resources and connotations and the formation of characteristic teaching.

Published: February 2024

The effect of caponization on the level of testosterone, biochemical bone markers as well as on the geometrical, densitometric, structural, mechanical and microstructural characteristics of the tibia of capons was the subject of this study. The study was conducted on 80 hybrids obtained from the crossing of Rhode Island Red (R-11) hens and meat roosters (Ross 308). Cockerels were surgically castrated at 8 week of age and then fattened until the 24th week of life. The results indicated that the serum testosterone (P<0.01), osteocalcin (P<0.05), and osteoprotegerin (OPG) (P<0.05) concentration were significantly lower, while the serum receptor activator of nuclear factor kappa-B ligand (RANKL) (P<0.01), RANKL/OPG ratio (P<0.05) and alkaline phosphatase concentrations (P<0.05) were significantly higher in capons. The tibia weight, the relative tibia weight, and the cross-sectional area of tibia were significantly higher (P<0.05) in cockerels, while capons had higher (P<0.05) body weight and transversal external diameter of tibia. Moreover, the bone ash, calcium and phosphorus content, bone mineral density and bone mineral content, and also yield load, ultimate load, work to fracture, as well as Young’s modulus, bending moment, yield stress and ultimate stress were significantly lower (P<0.05) in capons. Caponization also caused a significant reduction in the percentage volume of bone (P<0.05) in the proximal epiphyses of the tibia, as well as changes in its microarchitecture (P<0.05) (fewer trabeculae and connections between trabeculae, thicker trabeculae and larger spaces between trabeculae). Concluding, caponization disrupts the homeostasis and microstructure of the tibia, and this results in a decrease in the mechanical strength of the tibia, making it more susceptible to deformation.
Deciphering The Transcriptional Activities of Genes Coding For Adipokines and Their Receptors in Porcine Ex Situ-Protected Mesenchymal Stem Cells Undergoing Adipogenic Differentiation

Published: February 2024

The aim of this study was to investigate the impact of the source of mesenchymal stem cells (MSCs) and their adipogenic derivatives on the relative abundances (RAs) noticed for mRNA transcripts of the selected adipokines (adiponectin and leptin) and their receptors. MSCs were isolated from bone marrow (BM) and subcutaneous adipose tissue (AT ) samples collected post mortem from a total of four gilts (each at the age of 6 months). The stemness of the MSCs was proven via recognizing their abilities to differentiate into adipocytes, osteoblasts, and chondrocytes. By using real-time PCR (RT -qPCR), the quantitative levels of transcriptional activity pinpointed for the adiponectin (ADIPOQ), adiponectin receptor 1 (ADIPOR1), adiponectin receptor 2 (ADIPOR2), leptin (LEP), and leptin receptor (LEPR) genes were comparatively analyzed between non-differentiated AT -MSCs and BM-MSCs and their cell counterparts undergoing differentiation into adipocytes. A significantly higher RA for ADIPOR1 transcripts was identified in the AT-MSCs compared to the BM-MSCs and their adipogenic derivatives (P≤0.05). Moreover, the quantitative levels of LEPR transcripts were shown to increase significantly among adipocytes originating from differentiated BM-MSCs compared to undifferentiated BM-MSCs, AT -MSCs, and AT -MSC-derived adipocytes (P≤0.05). Nonetheless, there was no significant inter-group variability in the RAs of the ADIPOQ, ADIPOR2, or LEP mRNA transcripts (P>0.05). Cumulatively, the in vitro models focused on the identification and detailed exploration of transcriptomic signatures of undifferentiated pig BM- and AT -MSCs, and the molecular mechanisms underlying the adipogenic differentiation pathways of the above-indicated two distinct sources of stem cells were developed and optimized in the current investigation for the very first time. These ex vivo porcine models might confirm the expedited functional mobilization of ex situ-protected MSCs and their enhanced capacity to be transcriptionally reprogrammed into adipocytes due to physiopathological alterations in the expression profiles of adipokines and their receptors, which are prompted and progressed in obese and superobese women patients at the peri-pubertal period of ontogenesis. Finally, the models providing comprehensive molecular insights into ex situ-protected porcine BM- and AT -derived MSCs and their differentiated derivatives can be largely suitable for the biotechnologically assisted rescue and restitution of endangered representatives of rare native breeds of domestic pig.

The aim of the present study was to assess the effects of dietary supplementation with Lactobacillus salivarius (LS) ATCC 11741 and lutein (LU) on immunological, antioxidant, and growth responses, and resistance against Yersinia ruckeri infection in rainbow trout (Oncorhynchus mykiss). There were seven experimental diets containing un-supplemented diet (CTL), L. salivarius at 1 × 106 (LS6) and 1 × 108 (LS8) CFU/g, lutein at 50 (LU50) and 150 (LU150) mg/kg, L. salivarius at 1 × 106 CFU/g plus lutein at 50 g/kg (LS6+LU50), and L. salivarius at 1 × 108 CFU/g plus lutein at 150 g/kg (LS8+LU150). These diets were provided to the fish (N= 735; 14.0±0.38 g). After 60 days of feeding, all experimental treatments exhibited significantly higher growth performance, compared to the CTL treatment. The intestinal protease activity and the intestinal lactic acid bacteria population in the probiotic-treated fish were significantly higher than in the CTL fish. The intestinal lipase activity was only higher in the LS6+LU50 treatment, compared to the CTL treatment. Compared to the CTL treatment, the intestinal total bacterial count, and serum superoxide dismutase significantly increased in the LS6+LU50 and LS8+LU150 treatments. The serum catalase significantly increased in LU150, LS6+LU50, and LS8+LU150 treatments, and serum glutathione peroxidase significantly increased in the lutein-treated fish. All experimental treatments, particularly LS6+LU50 and LS8+LU150, had significantly lower serum malondialdehyde levels, compared to the CTL treatment. The levels of serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase in LU50, LS6+LU50, and LS8+LU150 treatments were significantly lower than the CTL. All experimental treatments showed significantly higher serum lysozyme (LYZ), complement, blood respiratory burst activity (RB), and skin mucus alkaline phosphatase (ALP), compared to the CTL treatment. The highest serum LYZ, C4, total immunoglobulin (Ig), blood RB activity, and skin mucus peroxidase, ALP, and Ig were observed in the LS6+LU50 and LS8+LU150 treatments. All the experimental treatments, especially LS6+LU50, exhibited significantly lower mortality after the bacterial challenge compared to the CTL. In conclusion, dietary supplementation with 1 × 106 CFU/g L. salivarius and 50 mg/kg lutein can maximally improve growth performance, digestive enzymes, antioxidant parameters, immune responses, intestinal lactic acid bacteria, and resistance against yersiniosis in rainbow trout.

The current study was carried out to explore the effects of lactofeed (LA) as a multi-strain probiotic and succinic acid (SA) on growth variables, gut lactic acid bacteria count, digestive enzymes, innate immune responses, antioxidant capacity, and resistance against yersinia ruckeri in rainbow trout juveniles (Oncorhynchus mykiss). Three hundred sixty healthy rainbow trout juveniles (13.21±0.41 g) were randomly divided into twelve tanks (300 L) as four experimental groups. They were fed with basal diet (Control; BD), FT1: BD + 1 g/kg LA, FT2: BD + 5 g/kg SA, and FT3: BD + 1 g/kg LA + 5 g/kg SA for eight weeks. According to the results, final weight (FW), weight gain (WG), protein efficiency rate (PER), and feed conversion rate (FCR) revealed a remarkable discrepancy compared to the control group. In addition, dietary inclusion of LA (FT1 and FT3) significantly increased the specific growth rate (SGR). Dietary supplementation of LA+SA (FT3) remarkably improved total bacteria count (TBC) and amylase activity compared to the unsupplemented group. Gut lactic acid bacteria (LAB) count and digestive protease activity in all supplemented fish were remarkably higher than in unsupplemented group. Blood immunological factors including white blood cell (WBC) count, total immunoglobulin content (Ig), and the activity of lysozyme (LYZ), alternative complement pathway (ACH50), and acid phosphatase (ACP) were significantly enhanced in the supplemented groups. Neutrophil (NEU) count, skin mucus Ig and hepatic glutathione peroxidase (GPX) increased in SA (FT2 and FT3) treatments. In addition, monocyte (MON) count and skin mucus LYZ activity were significantly elevated following feeding with the FT3 diet. Other immunological parameters of skin mucus including protease activity, alkaline phosphatase (ALP) activity, and ACH50 activity, as well as hepatic superoxide dismutase (SOD) and catalase (CAT) activities increased in fish fed with diets containing LA and/or SA. Malondialdehyde (MDA) value was remarkably decreased in all supplemented rainbow trout compared to the fish fed with BD. Disease resistance against Y. ruckeri in fish fed with supplemented diets significantly improved with respect to the results obtained in the control specimens. Overall, dietary LA+SA supplementation was beneficial to improve growth performance, gut LAB count, digestive enzyme activities, innate immune responses, antioxidant capacity, and disease resistance in rainbow trout. According to these findings, 1 g/kg LA + 5 g/kg SA is suggested for adding to rainbow trout diet.

Condition monitoring of oil-immersed in-service transformers to facilitate preventive maintenance is still a challenge. Monitoring of 2-Furfuryldehyde (2-FAL), released in the transformer oil as a result of paper insulation degradation, and moisture ingress can provide insight into the health of the insulation of transformers. Since 2-FAL and moisture are high dielectric constant contamination, capacitive sensor-based detection is a potential solution. A novel Inter digital Capacitive (IDC) sensor is reported in this paper to measure the concentration of 2-FAL and moisture uses Zinc Oxide (ZnO) as a sensing film. The sensor shows good sensitivity, approximately linear characteristics, and low characteristic drift.
What if There’s Greater Intimacy in the Collective?

In this research note, I track the reflective process of creating and facilitating a workshop series in Amman, Jordan, as a way in which to explore the (re)creation, (re)construction, and (re)negotiation of understandings of Palestinian cultural heritage and identity. The workshop centers around the idea of materiality from the Palestinian homes in Amman being framed as a “material witness” of exile. These material witnesses become an access point into the individual versus the larger transnational exilic experience. I introduce the idea of playing within a participatory heritage framework and how, by starting with the material witnesses from houses in Amman today, it enables a discussion on the modalities of exile, local identity formation, and the performativity of memory as part of an ongoing creative process of meaning-making. I also draw out discussions of playing with my own methodology practice and what it means for future research.

Objective: Informal employment in Latin America, especially in Peru, poses challenges to job stability, as workers' skills are not aligned with market needs, leading to increased unemployment and underemployment. It is crucial for universities that offer management programs in Peru to understand the labor market, identify the necessary competencies for their graduates, and update their curricula accordingly. This study analyzes the competencies required for management professionals in southern Peru, identifying gaps and proposing solutions to improve education-employment alignment.
 
Method: A survey with 33 multiple-choice questions was conducted among 41 private companies and 20 public institutions. Exploratory factor analysis was used to categorize competencies and the Wilcoxon test was used to determine the gap between the supply and demand of skills.
 
Result and Conclusion: The results reveal three categories of competencies: specific, interpersonal and technological, highlighting skills such as teamwork, adaptability to change, ethical behavior, commitment to quality, and decision making. A gap is observed where demand exceeds supply, indicating an unmet need for competencies, except in social responsibility and civic engagement.
 
Research implications: These findings are valuable for universities offering management programs in Peru, as they allow curriculum improvement and, consequently, optimize the teaching-learning process, as well as rationalize efforts and resources to meet labor market demands.
 
Originality/value: It addresses a real and relevant issue that affects both graduates and companies in the specific context of southern Peru, providing a more detailed and contextualized understanding of the challenges and opportunities in this region.
