“Yizkor”: A Case of Holocaust Memory Activism In a Czech Village

The article explores the construction and preservation of Holocaust memory in the small Czech village of Kosova Hora. The study, based on focus group interviews, reveals how local Holocaust memory is shaped by a unique combination of activism, local history, and communal practices. The article highlights the role of a Jewish couple who, by rescuing and restoring the village synagogue during the Communist era, created a central site for Holocaust remembrance. This act of preservation catalyzed broader local engagement, resulting in a collective effort to remember the Jewish community that once thrived there. The synagogue now serves not only as a cultural and educational center but also as a place for religious commemoration, despite the absence of a local Jewish population. The research concludes that such localized efforts are crucial for sustaining Holocaust memory, showing how minority activism can embed itself within majority memory, even in small and seemingly ordinary communities.The article explores the construction and preservation of Holocaust memory in the small Czech village of Kosova Hora.

Rocks, ridges, and recreation: The geotourism renaissance in Dhaubadi area of Gandaki province, western Nepal

This study aims to assess new and known sites along the Kawasoti–Dhaubadi–Dedgaun–Kaligandaki route for geotourism potential based on regional geology, geomorphology, and socio-cultural factors. This study includes the methods to identify geosites, geoheritage, and geomorphosites of the area by field visits including data collection and mapping. It explores the diverse tectonic zones including Dun Valley, Siwalik and the Lesser Himalaya bound by significant tectonic features like the Central Churia Thrust, the Main Boundary Thrust, and the Devachuli Thrust. The presence of plant fossils in Siwalik and Gondwana rocks, the renowned Dhaubadi iron deposit, and coal seem to enhance the geotourism potential. The Ramche landslide can be emphasized as a site for landslide research. The region   features from the lowland of Narayani River with the Chitwan National Park to the Ghoral Conservation Area at high hill morphology. The captivating experiences of the Dhaubadi area’s changing climate, panoramic mountain views, and the Kali Gandaki River enhance its charm parallelly with cultural and historical sites like Maharajathan, Devachuli temples, and Rudrapurgadi. The unique culture of the Tharu and Magar community and trekking sites like Dhaubadi and Devachuli hills boost the potential of the area. Overall, the study highlights the Dhaubadi area’s geotourism scenarios and proposed for in-situ geoconservation and geoparks development

Transgenerational Holocaust Memory In Slovakia: From Forgetting to Ambivalence About the Roots of Hatred

This article explores Holocaust memory in Slovakia, shedding light on how Slovak citizens perceive this past and its transgenerational transmission. The data presented were gathered in 2023 through ethnographic fieldwork and focus group interviews with informants belonging to three generations (between ages of 18 and 95), in three different locations across the country: Krupina, Prešov, and Bratislava. The initial findings show that Slovakia has been moving from indifference towards the Holocaust to the limited capability of realizing the actual causes and effects of atrocities, while at the same time officially accepting the commemorative centrality of the Holocaust.This article explores Holocaust memory in Slovakia, shedding light on how Slovak citizens perceive this past and its transgenerational transmission.

The St. Petersburg paradox with state dependent linear utility functions for monetary returns. A note

In the experiment underlying the St. Petersburg paradox, we use state-dependent linear utility functions for money with a countably infinite set of states of nature to show that a potential participant will be willing to pay no more than a finite sum of money to participate in the experiment

Information - Modern Theories

This review deviates from the usual approach to the topic of information by not focusing on Shannon’s Theory of Communication (TOC) and the related or derived concepts. In addition, we do not talk at length about information in relation to knowledge, data, communication, information processing, or similar concepts. Instead, we endeavor to reappraise our understanding of information without favoring any specific perspective. We know a lot about information, and the various conceptualizations of information presented in this paper are proof of this. Nevertheless, we also show that some lingering unresolved questions remain about the nature of information. To somewhat stem the appearance of further new concepts of information, we consider two perspectives, namely ontological and epistemic, and posit that we can potentially reduce all information variants to just these concepts. We then look at two general theories of information: the General Definition of Information (GDI) and the General Theory of Information (GTI), arguing that the GTI appears to be the better of these two options because it is more fundamental and comprehensive with deep metaphysical roots. Finally, we review some recent studies about information’s physical nature, such as for information and mass, meaningful physical information, and the persistence of information. This review, like all reviews, is selective and synthetic, but the extensive reference list provides the necessary resources to explore the discussed ideas in greater detail, as well as study the recent works on the nature of information

Spatial variation on hydrogeochemical parameter in the Hetauda Valley, central Nepal

Water is a requisite source for human survival, facing increasing issues and challenges in terms of both quantity and quality due to exacerbated global populations and urbanization trends. This increased demand has caused a decline in the overall availability and quality of water resources. Hetauda, serving as the administrative center of Bagmati Province, has emerged as a key destination for employment services along with a good potential zone for geotourism closely connected to its diverse geological features and water resources. However, excessive utilization, depletion, and extensive pollution of surface water sources in the region have underscored the importance of exploring groundwater for agricultural, and domestic needs along with decreasing the possibilities for geotourism. As the study area lies in the Hetauda Valley, to address this concern, water samples from 34 different sources such as dug wells, boreholes, and springs were collected. A thorough analysis of physicochemical parameters was conducted to evaluate water quality, revealing notable variations across locations, including the presence of iron and arsenic traces in specific samples. The Weighted Arithmetic Index Method was used to calculatethe Water Quality Index (WQI) showing that certain water sources had very good quality while few weren’t appropriate for human consumption. The Piper diagram indicates the dominancy of calcium ions in cations and chloride in anions. The stiff diagram shows that the ions Na + K > Ca > Mg dominate the composition of the cations, whilst HCO₃⁻ > Cl⁻ > SO₄²⁻ dominates the anions. Besides, the multivariate statistical analysis through Principal Component Analysis was executed to support these hydrochemical findings. In conclusion, this research underscores the critical necessity for sustainable water management strategies in the study area, advocating for the prudent exploration of groundwater while addressing the challenges posed by contaminants, thus ensuring the availability of safe and sufficient water resources in the region

IMPROVING PET SCANNER TIME-OF-FLIGHTRESOLUTION USING ADDITIONAL PROMPT PHOTON

Positronium Imaging requires two classes of events: double-coincidences originated from pair ofback-to-back annihilation photons and triple-coincidences comprised with two annihilation photonsand one additional prompt photon. The standard reconstruction of the emission position along theline-of-response of triple-coincidence event is the same as in the case of double-coincidence event;an information introduced by the high-energetic prompt photon is ignored. In this study, we proposeto extend the reconstruction of position of triple-coincidence event by taking into account the timeand position of prompt photon. We incorporate the knowledge about the positronium lifetime distributionand discuss the limitations of the method based on the simulation data. We highlight that theuncertainty of the estimate provided by prompt photon alone is much higher than the standard deviationestimated based on two annihilation photons. We finally demonstrate the extent of resolutionimprovement that can be obtained when estimated using three photons

Occurrence of Chunky graphite in ductile cast iron solution strengthened by silicon

Solution strengthened ferritic cast iron is characterised in EN 1563:2018 (and also in ISO 1083:2018) as grades EN-GJS-450-18, EN-GJS-500-14 and EN-GJS-600-10. Machine and plant builders have been using this material in new designs since 2011. The strength and ductile properties, competitive in comparison with the previous classical ductile cast iron grades, make it possible to reduce the weight of castings. Particularly preferred is grade EN-GJS-600-10 with UTS min. 600 MPa and A min. 10%. Strengthening of the ferritic matrix is possible due to the content of approximately 4.2% of silicon in the cast iron. In casting practice, this material is difficult to produce in a stable manner due to the frequent occurrence of degenerate Chunky graphite in the casting structure, resulting in a loss of ductile properties of the cast iron. In this article,  an analysis has been made, based on literature, of the occurrence of strong negative segregation of silicon in classical ductile cast iron. Own research has confirmed the occurrence of chunky graphite in the cast. Dendritic crystallisation of austenite and strong segregation of silicon favours the formation of Chunky graphite. A much stronger proportion of silicon was found in the Chunky graphite zone, compared to the adjacent ball graphite zone.  The introduction of micro-additives into the liquid melt eliminated the presence of Chunky graphite in the casting. The applied modifiers of graphite and metal matrix (hybrid modification) seem to be an effective method to stabilise the technological process of this innovative casting material
