Encountering Folk, Knowledge, and Place
Authors: Nadarajah Yaso , Grydehøj Adam
Published: December 2024

Studies of culture, history, literature, and art can provide insight into our multiple senses of place. The manner in which we speak, write, illustrate, and produce our landscapes; the politics of land use; and life on land or sea (or away from it) reflect human efforts to live locally. Similarly, studies of ecologies, landforms, weather, and other natural phenomena can teach us about how people spatialise and make homes in the world. Culture, lifeworlds, and place can be mutually constitutive, and knowledge is situated. In this paper, the co-editors-in-chief of ‘Folk, Knowledge, Place’ journal introduce ourselves and show how our collective work has demonstrated the need for this journal. We then discuss theoretical frameworks; introduce our approach to researching in-between between disciplines, places, and theories; and present how the journal is published.

Millennials’ intentions to buy plant-based meat alternatives: insights for quick-service restaurants.
Authors: Incardona Giuseppe , Gebbels Maria , Nguyen Thi Hong Hai
Published: December 2024

Rapid population growth, shifting consumption patterns, and environmental stresses are challenging food security, raising concerns about the global food system's ability to sustainably feed the projected 9.3 billion people by 2050. Additionally, the increasing demand for Quick-Service Restaurants (QSRs) (also known as ‘fast-food chains’) intensifies environmental concerns. Their large-scale food production and factory farming practices contribute significantly to environmental degradation and animal welfare issues. In response to growing consumer awareness of environmental issues, QSRs have begun incorporating plant-based meat alternatives into their menus to align with sustainability objectives and appeal to eco-conscious consumers, particularly millennials. However, these alternatives face acceptance challenges due to perceptions of being highly processed and potentially containing genetically modified organisms. It is therefore essential to have a better understanding of the market’s purchasing intention to effectively market plant-based meat alternatives and advance QSRs’ sustainable practices.

obligaciones erga omnes como piezas de la construcción de relaciones justas y de comunidad
Authors: Carrillo-Santarelli Nicolás
Published: December 2024

El reconocimiento de las obligaciones erga omnes en la jurisprudencia y la doctrina son consideradas como revolucionarias, debido a cuán diferentes resultan ser sus dinámicas en comparación con aquellas de otros deberes basados en la lógica de la reciprocidad. No obstante, la legitimación y autorización que otorgan a terceras partes a exigir el cumplimiento de las mismas son tan sólo una de sus importantes implicaciones, que son tanto jurídicas como no jurídicas. Ambas se fundamentan en cómo aquellos deberes apuntan a la existencia de valores comunitarios internacionales. La dimensión comunitaria jurídica internacional no se limita a autorizar sino que, en ocasiones, va más allá y exige a los sujetos del derecho internacional a esforzarse con diligencia para garantizar el respeto de los bienes jurídicos que ella protege, revirtiendo ilícitos continuados. Así como se ha considerado que desde un punto de vista ético deberían desobedecerse órdenes jurídicas viciosas, las características de los deberes erga omnes y una consideración moral de la “dependencia única”, pueden llevar al reconocimiento de cargas jurídicas y no jurídicas de terceros actores de recurrir a las opciones que ellos ofrecen, con tal de proteger a quienes estén en situación de vulnerabilidad.
Explorando la utopía de la justicia restaurativa en la Corte Penal Internacional
Authors: Gil Gandía Carlos
Published: December 2024

Desde la Segunda Guerra Mundial, la justicia penal internacional ha priorizado sancionar a los responsables de crímenes, relegando a las víctimas a un papel secundario, como testigos. El Estatuto de Roma introduce un cambio al reconocer sus derechos a participar activamente en los procesos y recibir reparación, marcando un avance hacia un modelo más inclusivo. Sin embargo, este enfoque aún presenta limitaciones ya que el sistema sigue enfocado en la retribución y no tanto en la reparación y cuanto menos en la reconciliación. La justicia restaurativa emerge como una alternativa que busca no solo castigar, sino también reparar el daño y restaurar el tejido social. Este enfoque, propuesto en casos como Lubanga, enfatiza la participación directa de las víctimas en la reparación y el diálogo con los infractores, fomentando la reconciliación. A pesar de avances como la participación en procesos y la creación del Fondo Fiduciario, la Corte Penal Internacional enfrenta desafíos en implementar un modelo restaurativo integral. Para avanzar, se proponen reformas que fortalezcan el papel activo de las víctimas en todas las etapas del proceso, incluyendo mecanismos procesales de justicia restaurativa. Estos pasos serían clave para transformar la justicia penal internacional en un sistema efectivo en la simetría entre víctima y victimario, orientado hacia la paz y la no repetición de los crímenes.
De “Lubanga” a “Ongwen”: reparaciones con perspectiva de género en la Corte Penal Internacional
Authors: Montero Ferrer Carmen
Published: December 2024

Transcurridas dos décadas desde que la Corte Penal Internacional (CPI) iniciase su andadura, hoy podemos afirmar que la práctica procesal de este órgano ha supuesto un verdadero giro en la forma de entender el papel ejercido por las víctimas en el sistema de justicia penal internacional. Por primera vez, se les reconoce su derecho a participar en el procedimiento y a ser reparadas. Para adquirir la condición de víctima es necesario que las personas naturales o jurídicas acrediten haber sufrido un daño como consecuencia de la comisión de algún crimen competencia de la CPI. Es decir, las víctimas, siguiendo el criterio de “proximate cause”, han de probar que el crimen está suficientemente conectado al perjuicio como para ser la causa de este. Con todo, en sus últimas decisiones, la CPI está realizando una interpretación extensiva de este criterio, ampliando los tipos de daños considerados y, en consecuencia, los grupos de víctimas que podrán participar en los procedimientos o ser reparadas. Esta comunicación se refiere a algunas de estas decisiones, prestando particular atención al reconocimiento al daño transgeneracional sufrido por los niños nacidos de mujeres víctimas de violencia sexual y de género. La cuestión que nos planteamos es, si al hacerlo, la CPI está cumplimiento o no con el mandato de género recogido en el artículo 54.1. b del Estatuto de Roma.

Published: December 2024

The content of heavy metals both in plants and in soils for growing agricultural crops steadily changes the state of ecological safety of the corresponding biocenosis. An increased amount of trace elements and compounds of heavy metals causes metabolic disorders in plant tissues. As a result, there is an accumulation of toxic elements in the crops, which disrupts the biocenosis in the system for both farm animals and humans. Therefore, the contamination of plant raw materials, in particular chicory, for the food industry with ions of heavy and toxic metals is a significant environmental problem. The results of studies of the content of trace elements and their interaction with carbohydrates of vegetable inulin-containing raw materials are presented. X-ray fluorescence analysis was used to determine the content of 20 macro- and microelements in chicory roots. The regularity of changes in the content of microelements depending on heat treatment, in particular in harsh conditions, has been proven. The method of non-destructive analysis of the content of mineral components of plant raw materials using carbohydrates as a matrix for measurements has been developed. At the same time, it practically does not affect the course of the study of the appropriate type of carbohydrates to determine this or that mineral component. According to the results of the experiments, a group of samples was recommended for the determination of such elements as Cd, Zn, Pb and Hg, and the corresponding calibration curves were constructed.

Authors: Santiago Carvalho Marília , Godinho de Abreu Carlos , de Figueiredo Vilela Leonardo , Cardoso e Bufalo Tatiana , Souza Dias Eustáquio
Published: December 2024

Mushroom cultivation generates enormous amounts of post-cultivation substrate at the end of each production cycle, which is known as spent mushroom substrate (SMS). Once known as a waste product of mushroom production, SMS is actually a valuable co-product of mushroom production. There are countless possibilities for using this material and, considering the large volumes produced, it is interesting to continue looking for new alternatives for its use in different human activities. In this work, we evaluated the potential for biosurfactant production in SMS from different species of oyster mushrooms, in addition to evaluating the potential for oil degradation in the presence of SMS from Pleurotus ostreatus and Lentinula edodes. Even with the use of dry SMS, a decrease in several hydrocarbons was observed after 3 months of oil treatment. Furthermore, Pleurotus species showed high emulsification rates. Future studies will be necessary to characterize the molecules responsible for the bioemulsification activity, since both biosurfactants and bioemulsifiers can act in a similar way.
Challenges and obstacles to the implementation of sustainable development goal 6 in Ukraine (case of the Ros’ River)
Authors: Berezovyi Vlas , Kharchenko Viacheslav
Published: December 2024

Goal 6 of the sustainable development is “Clean water and sanitation” (“Ensure availability and sustainable management of water and sanitation for all”). Protection, sustainable use and restoration of water resources are urgent tasks for Ukraine, especially in the conditions of a full-scale war. The paper considers challenges and obstacles on the way to achieving sustainable use of water resources of the Ros’ River. Achieving goal 6 should mean improving the work of water-using enterprises (sewage treatment facilities, hydroelectric power plants, etc.) in such a way as to minimize their negative impact on the ecological state of the Ros’, which in turn should ensure the proper quality of water for water supply, land reclamation, and tourism and recreation. The focus is on the form of ownership (state or private) of enterprises that use water from the Ros’ River, how this or that form of ownership encourages enterprises to use water resources carefully, as well as the presence and effectiveness of mechanisms of influence on violators of environmental protection legislation of Ukraine in this field. In 2022 the special petition to the President of Ukraine was created and signed (E-petition…). It was called “About the development and implementation of a project to save the Ros’ River with its further use to restore the water supply of all rivers of Ukraine and their tributaries – small rivers.” Taking into account the status of Ukraine as a candidate for accession to the European Union, it makes Ros’ River being a good object for the investigations.

Experimental research of a pumping engine in a micro-ORC system with a low-boiling medium
Authors: Kaczmarczyka Tomasz Z.
Published: December 2024

The paper presents the results of experimental research on a pumping engine with the low-boiling medium HFE-7100. The research was conducted in a micro-ORC system with an output of about 2.5 kWe. Among other factors, the impact of working medium temperature and pump rotational speed on the operating parameters of the gear pump and pumping engine is analyzed. The research shows that increasing the rotational speed and HFE-7100 temperature resulted in an increase in the power consumed by the pump drive and an increase in the effective power of the pump. The increase in the effective power of the pump was greater than the electrical power consumption of the pump drive, resulting in an increase in the volumetric efficiency of the pump. It has been established that, at a constant pump rotational speed of 2000 rpm, increasing the average temperature of HFE-7100 by 27 K from approximately 304 K resulted in a 4% increase in the pump's volu-metric efficiency to 80%. It has been established that, for any value of pump rotational speed and working fluid tempera-ture, there exists an optimal effective power value for the pump at which the pumping engine achieves the maximum efficiency.

This study compares solar air heaters equipped with W-contoured, taper-contoured, and reverse taper-contoured turbulators. It examines heat transfer coefficients, pressure drops, velocity contours, turbulent kinetic energy contours, and thermal perfor-mance factors for these systems under varying operating conditions. The air Reynolds number ranges from 4000 to 18 000, while design parameters such as relative roughness height and relative pitch ratio remain constant for accurate comparison. The simulations were conducted with a uniform heat flux of 1200 W/m2. The W-shaped contour roughness achieved the greatest heat transfer coefficient, surpassing both the tapered and reverse tapered configurations. In terms of friction factor, the tapered contour on the absorber plate led, followed by the reverse tapered and W-shaped contours. Overall, the W-shaped contour delivered the best performance. At lower Reynolds numbers, the reverse tapered contour outperformed the tapered contour, whereas at higher Reynolds numbers, the tapered contour showed superior performance compared to the reverse tapered contour.

Enhancements in gas turbine blade cooling techniques, such as film cooling, have significantly advanced the aerothermal effi-ciency of turbines, especially in transportation sectors like aeronautics and automotive industries. This study aims to enhance turbine blade cooling by incorporating an obstruction at the jet exit. The vortex generator angle has been modified to 25°, 45°, 60°, 90° and 110°. These five designs were assessed in comparison to the conventional cylindrical hole configurations. Two injection ratios (M = 0.25, and M = 0.5) were studied within the ANSYS CFX 16 software, utilizing the finite volume method to solve the average Reynolds equations and the energy equation. The findings show qualitative alignment with experimental data for the base scenario, indicating that the vortex generator angle notably amplifies film cooling effectiveness. Typically, the vortex generator configured at 90° exhibits a stronger mixing capability compared to the other cases and cylindrical design.
First record of the freshwater sponges (Spongilla) in the inland rivers of Bulgaria

Records from freshwater sponges on Bulgarian territory are scarce. Only two exist in the scientific literature, one from the Zhrebchevo Dam and one from the Bulgarian part of the Danube River near the border with Serbia. Inland lotic ecosystems such as channels, streams, and rivers, as well as lentic ecosystems, were not studied for this potential biological indicator. Due to the existing knowledge gap, studies of entire rivers and other aquatic ecosystems focused on the monitoring of biological or physicochemical quality elements should be vigilant for Spongillidaе family representatives since even their random discovery and identification could be of great importance. Such records can be considered interesting for gaining knowledge of their distribution, species richness, habitat preference and particular environmental variables dependencies. We investigated macroinvertebrates and macrophytes from 16 sampling sites in a river with a length of about 200 km and a watershed of 1600 km2 to register two Spongilla lacustris individuals at two sites without any significant hydro-morphological pressure from big dams. Our results could serve for monitoring program optimization that aims to investigate rare protected species dependent on freshwater sponges and on seeking more localities with established Spongilla populations. This can be achieved by directing sampling efforts on sampling sites that have similar habitats and have a hydraulic connection with the found specimens.

Authors: Dochev Veselin
Published: December 2024

On soil type calcic chernozem, in the period 2018-2022. an experiment with common winter wheat (Triticum aestivum L.) variety "Venka 1" was carried out. The experiment was set up in 4 replications in a randomized block design. The size of the experimental plot is 10 m-2. In October, the sowing was carried out after the predecessor sugar beet (Beta vulgaris L.), with 500 germinating seeds/m-2. Treatments in 4 variants are applied in the appropriate periods according to Maria Thun's calendar. The first variant is an untreated Control; the second was treated only with biodynamic preparations: VD (biodynamic preparation) 500 + VD 501 + Fladen preparation; The third option is treated only with biological preparations: Free N + Heliosulfur, and the treatment in the fourth option is a combination of the above two options: VD (biodynamic preparation) 500 + VD 501 + Flaten preparation + Free N + Heliosulfur. Growth phases indicated are according to the Zadoks scale. Data were processed using SPSS using the method of variance statistics. Student's criterion was used for assessment. It was found that wheat treated variants performed better in terms of some biochemical parameters.
Culture and the much-more-than-human: the case of colloids
Authors: Szerszynski Bronislaw
Published: December 2024

In this paper I try to identify a minimal definition of culture that might be applicable in the much-more-than-human realm that extends beyond organic matter and human involvement. I speculate that culture conceived in this broad way might be a metapattern or ‘machinic solution’ available to matter of diverse kinds, organic and inorganic. I explore how this idea might apply this to colloids – hybrid forms of matter such as sols, foams and gels that are mixtures of matter in different phase states, some continuous and some discontinuous, and which can behave in complex ways that mix features of solid and fluid behaviour. I conclude by suggesting that attending to both the similarities and differences between ‘culture’ in the organic and in the inorganic realms might force us to rethink our understanding of both.
Applying machine learning method in stock trading by indicator

The stock market is always considered a highly potential investment channel for the public. However, unpredictable fluctuations often require investors to continuously monitor and analyze the market with a huge amount of data. This research was conducted to implement machine learning methods in automated stock trading based on indicators, aiding investors in evaluating the effectiveness of trading strategies based on these indicators and suggesting the most appropriate investment portfolios, thus minimizing the time and effort spent on data processing. Specifically, the application process we developed and implemented involves four steps: (i) data collection, (ii) automated trading based on indicators (SMA, Bollinger Bands, RSI, MACD), (iii) building an optimal investment portfolio based on automated trading results using the Sharpe ratio method, and (iv) testing and evaluating the trading results with new data. Using data collected from VN30 stocks, the study results demonstrate that trading based on indicators and proposing an optimal investment portfolio yields high-profit rates and minimizes investor risks.
Sustainable tourism indicators for cities from tourists’ perspectives: the case of Da Lat, Vietnam
Authors: Truong Thi Lan Huong , Nguyen Thi Thanh Ngan
Published: December 2024

Urban destinations, housing over half the world’s population, are overlooked in sustainable tourism research. Effective management requires selecting sustainable indicators, which are crucial for assessing economic, social, environmental, and governance aspects. However, systematic sustainability appraisal in tourism is still nascent, with previous studies lacking tourist perspectives. This study explores how tourists perceive sustainable tourism indicators in the context of a city destination. The study uses a quantitative approach with an online questionnaire featuring 53 sustainable tourism indicators, surveyed among 305 tourists in Da Lat, a well-known tourism city in the Central Highlands, Vietnam. Descriptive statistics based on mean analyses show that institutional sustainability indicators received the highest score, while environmental indicators were reported with the lowest score in the tourists’ view. The exploratory factor analysis of the importance given to sustainability indicators identified seven factors: 1) Institutional sustainability, 2) Socio-cultural sustainability, 3) Environmental sustainability, 4) Negative environmental impacts, 5) Urban Identity, 6) Sustainable labor in tourism, and 7) Negative socio-cultural impacts. The sustainable tourism development in Da Lat needs to consider the city’s internal issues concerning the planning and management of urban identity. The results demonstrate tourist awareness of sustainability issues and that, in the long run, this awareness might lead to changes in tourist preferences. Tourists see themselves as contributors, helping to enrich the city instead of contributing to overusing available resources. This research shows a more multidimensional sustainable tourism than the classic concept definition from tourists’ perspectives. The findings also highlight sustainability dimensions enhancing tourist experiences.
