Rapeseed stalks (Brassica napus), an abundant agricultural residue, represent a promising non-woody raw material for the pulp and paper industry. This study focuses on the chemical and structural characterization of alkali lignins isolated from black liquors generated by two common delignification methods: Kraft and Soda-Anthraquinone Pulping of rapeseed stalks. The objective is to understand how the chemical environment of each process influences the final structure, fragmentation degree, and reactivity of the isolated lignin. In practice, lignin samples are recovered from black liquors produced under varying conditions (alkali charge, time, and temperature) to achieve defined levels of delignification. Detailed characterization was performed using advanced analytical techniques, including Gel Permeation Chromatography, Solid-State Cross-Polarization/Magic-Angle-Spinning Nuclear Magnetic Resonance, and FT-IR and UV-Vis Spectroscopy. The findings provide essential data on the structural differences, confirming the suitability of the resulting materials for potential high-value applications. Furthermore, the structural similarities and performance indicators suggest that the Soda-AQ process enables successful delignification of rapeseed stalks without the sulfur emission issues associated with the Kraft method, thus validating the former as an environmentally cleaner alternative for non-wood biomass utilization supporting the complete valorization of rapeseed agricultural waste.

Blackberry (Rubus L.) cultivation in Kazakhstan is constrained by the limited availability of certified planting material and the absence of standardized micropropagation protocols adapted to local conditions. This study aimed to optimize the key stages of in vitro culture for the cultivars ‘Natchez’, ‘Black Magic’, ‘Osage’, and ‘Heaven Can Wait’, including explant sterilization, culture initiation, shoot multiplication, and acclimatization. A sequential sterilization scheme using 70% ethanol followed by 1% sodium hypochlorite ensured high explant survival. Shoot initiation was most efficient on MS medium supplemented with 0.1 mg/L BAP, whereas multiplication was enhanced by 0.5 mg/L BAP and 0.1 mg/L GA₃. In the subsequent rooting stage, microcuttings formed stable root systems under ex vitro conditions in agroboxes, confirming that the optimized protocol ensured not only high survival during initiation but also a successful transition to the rooting phase, which is essential for further acclimatization. During ex vitro acclimatization, the application of humic acid, nanosilicon, or succinic acid improved survival under agrobox microventilation. The developed approach provides a reliable framework for producing healthy, adapted plants of the evaluated cultivars and contributes to establishing domestic propagation systems for reducing reliance on imported planting material.

In the period between 2021 and 2022 immediately following the COVID-19 lockdowns, there were 37 professional or academic productions of The Tempest in the United States. The play was by far the most produced of Shakespeare’s works in this timespan, and those 37 productions represent a 280% increase compared to 2019, in which there were 13 such productions. Considering The Tempest’s hyper-popularity within the context of the Black Lives Matter Movement and the birth of We See You White American Theatre’s calls for reform in 2020, this paper seeks to understand anew the way in which Shakespeare constructs blackness in the play. Indeed for all of its beauty and magic, The Tempest stages a violent anti-blackness in its treatment of Caliban. In particular, I argue an unexplored connection between The Tempest and Ben Jonson’s 1605 court masque, The Masque of Blackness, itself an exploration of the construction of race for a particular early modern audience. My exploration here began as a partial answer to a question posed by Robin Alfriend Kello: “how do you balance [an] attraction to the richness of Shakespearian verse against these layered histories of racial violence and exclusion?” A deeper understanding of Shakespeare’s version of blackness may grant insights into areas of intervention for those theaters reaching for The Tempest amidst national calls for anti-racist theatrical work.

Curiosity lies at the heart of the sixteenth-century miscellany books, which served as precursors to the essay genre. Among them, a truly exceptional piece stands out: La silva curiosa by Julián de Medrano, published in 1583. This work pushes the boundaries of curiosity to such an extent that it challenges its classification within the genre of miscellany owing to its unconventional and strange nature. Julián de Medrano, the author of this outlandish work, transforms himself into a character and protagonist, defining himself as an “extremely curious” individual. During his extensive travels, he curates a collection of “curious” epitaphs associated with often comical and peculiar deaths, spanning Latin, Spanish, Portuguese, French, Galician, and Italian. In addition to this, La silva curiosa includes an autobiographical narrative, a precursor to the Gothic genre, in which Medrano recounts unsettling encounters with black magic. This work offers a multifaceted exploration of curiosity, taking it to the extreme by narrating the author’s life experiences driven by a relentless pursuit of the curious, which is synonymous with the bizarre, extraordinary, marvelous, and unexpected. La silva curiosa emerges from a time marked by an almost nihilistic void, as the full force of the Baroque era has not yet arrived, and the ideals of humanism are fading away. It stands as a unique document that unveils an unexpected facet of the concept of curiosity within Spanish Renaissance culture. Full article

Afrofuturism (an artistic perspective in which Black voices tell alternative narratives of culture, technology, and the future) and the Dark Fantastic (interrupting negative depictions of Black people through emancipatory interpretations of art) are two interrelated concepts used by Black artists in the Atlantic World to counter negative images and emphasize a story from a Black perspective. Likewise, these concepts have been used to recreate and re-narrate history with an eye towards subverting white supremacist historical narratives. By using Afrofuturism and the Dark Fantastic as lenses through which texts by authors from the African Diaspora in the Atlantic World are examined, an alternative narrative of Black histories and futures concerned with revolution, liberation, and justice can be seen. The two texts that are the subject of this research include José Antonio Aponte’s descriptions of his book of paintings under interrogation in 1812–1813, and Martin Delany’s novel Blake; or the Huts of America (1859–1862), providing images of enslavement that run counter to a white supremacist telling of history. They both imagine alternative pasts and futures for Africa and the Afro-Diaspora involving revolution and magic. These works, though produced at different times and locations in the nineteenth century, offer new ways in which to discuss liberation and freedom in the context of the artistic production of the Atlantic World.

Bantu African divination is firmly established in South Africa in the context of modernity and is protected, endorsed and regulated by law. It is received in the therapeutic field. Important explorations were performed in the early 20th century by psychiatrists and psychoanalysts of Jungian orientation. Their cultural, philosophical, spiritual, and academic backgrounds are relevant to this reception. Jungian thought, Spiritual Spiritism, and traditions of European philosophy of divination resonated with the experience, observation, and understanding of Bantu divination. (‘Bantu’ designates the cultural and linguistic realm from Cameroon and Kenya southwards). Religious-philosophical traditions, as well as the conceptualisations of ‘divination’ by Plutarch and Iamblichus, are preserved. The reception and appreciation of Bantu divination in South Africa emerged from it, and resonated with these European traditions of religious-philosophical thought. Out of this development a distinct ‘South African modernity’ emerges. A parallel reception process developed in Brazil, in the belief systems of Umbanda and Kardecism. These developments are illustrated at present in the literatures of South Africa and Brazil, specifically in Afrikaans literature, black South African poetry and its poetics, and Magic Realism in Brazilian literature. Lastly, a perspective is offered of modernity’s reception by black scholars and diviners, continually interacting with Jungian psychoanalysis. Full article

Morinda citrifolia L., commonly known as noni or ‘Ahu’ in Sri Lanka, has traditionally been used for medicinal and black magic practices. However, noni also has therapeutic benefits and is used in various products like fresh juice, nutraceuticals, wine, powder, and puree. This study aimed to compare the bioactive compounds and antioxidant, anti-inflammatory, and antidiabetic potential of dried noni fruit and seeds using spectroscopic methods. Noni seeds exhibit significant antioxidant properties like dried noni fruit. They also possess antidiabetic and anti-inflammatory potential, making them valuable for food production, suggesting their utilization alongside noni-fruit-based products in Sri Lanka. Full article

I. The arena of quantum mechanics and quantum field theory is the abstract, unobserved and unobservable, M-dimensional formal Hilbert space ≠ spacetime. II. The arena of observations—and, more generally, of all events (i.e., everything) in the real physical world—is the classical four-dimensional physical spacetime. III. The “Born rule” is the random process “magically” transforming I into II. Wavefunctions are superposed and entangled only in the abstract space I, never in spacetime II. Attempted formulations of quantum theory directly in real physical spacetime actually constitute examples of “locally real” theories, as defined by Clauser and Horne, and are therefore already empirically refuted by the numerous tests of Bell’s theorem in real, controlled experiments in laboratories here on Earth. Observed quantum entities (i.e., events) are never superposed or entangled as they: (1) exclusively “live” (manifest) in real physical spacetime and (2) are not described by entangled wavefunctions after “measurement” effectuated by III. When separated and treated correctly in this way, a number of fundamental problems and “paradoxes” of quantum theory vs. relativity (i.e., spacetime) simply vanish, such as the black hole information paradox, the infinite zero-point energy of quantum field theory and the quantization of general relativity.

George Floyd’s murder by a Minnesota police officer sparked outrage, protests, and a re-evaluation of racial inequities in America. Within criminology, we argue, that re-evaluation should include the Latino Paradox, the idea that Latino communities are an exception—a paradox—in that, while they face economic deprivation, they also possess a magical something that makes them resistant to social problems like crime. Unfortunately, this compels the more delicate question; what is the deficiency in Black communities that makes them so vulnerable to crime? However, as we argue here, the Latino Paradox forces a false comparison. Its assumptions with respect to crime are factually incorrect, it demeans Blacks by neglecting their historical context, it romanticizes the Latino experience, and it misdirects policy making. It also leads to lazy theorizing by suggesting that the Latino Paradox forces a re-evaluation of a major criminology theory, Social Disorganization. Indeed, Social Disorganization Theory can adequately explain past and present links between immigration and crime. In light of these problems, it is time to drop the Latino Paradox as an explanation for the race/ethnic differences in crime. Full article

People have traditionally relied on fish to supply their major food and healthcare needs all across the world. However, there has been little focus on the traditional dietary, cultural identity, and integrity of traditional food systems in many rural Himalayan populations. The current study looks into the use of fish in traditional food and foraging practices, as well as its role in local traditional medicine and cultural practices. Semi-structured interviews and group discussions were used to collect data in the years 2020–2021. The data were analyzed using various statistical indices such as the fidelity level (FL), rank order priority (ROP), and relative popularity level (RPL). The data were then classified through a heat map, and ordination techniques were used to refine them even further. The current study identified 20 fish species of five families, with Cyprinidae (70%) as the dominant family. Three unique traditional fish preservation techniques were documented, namely: (1) smoking, (2) sun drying, and (3) pickling. The smoked fish are locally called fari, sun-dried fish are known as hugaad, and pickled fish are gaad anchaar. As a result of rapid modernization, fish has become a symbol of social class in the valley. In total, 17 diseases were identified, with joint pain being treated by the greatest number of species (N = 10). Flesh (43%) was the most commonly used part to treat various diseases. The mode of application of various fishbody parts for treating a variety of diseases was most commonly peroral (65%), followed by topical (35%). Schizopyge niger demonstrated the highest level of fidelity (82%) for joint pain. Schizopygeniger, Schizothorax curvifrons, Catla catla, Schizothorax esocinus, Schizothorax labiatus, and Schizothorax plagiostomus were the most popular (relative popularity level = 1.0). The rank order priority of six species was above 55 (Schizothorax plagiostomus (59.18), Labeo dyocheilus (61.99) Schizothorax labiatus (64.28), Schizothorax esocinus (68.36), Schizothorax curvifrons (73.19), and Schizopyge niger (82)). Two principal groups of six ethno-zoological categories (medicine, food, black magic, poultry, agricultural, and recreational) were identified using cluster analysis. Fish are also important as a source of livelihood and are closely associated with a local ethnic group known as Hanji/Haanz, who have extensive knowledge of ecology of the local fish species. Our research will contribute to filling a knowledge gap in the Kashmir Himalayan region, with policy implications for the protection and preservation of high-quality traditional knowledge for future generations. The findings of this documentation study can be used as an ethnopharmacological foundation for selecting fish in future pharmaceutical research. Full article

The future is not what it used to be. A new strain of futurism has taken over the stage of global science-fiction: one whose understanding of the future cannot be distinguished from its understanding of the present. Gone are the days when extraterrestrials in shiny, extravagant outfits mastered fascinating technologies that flirted with magic. Characters in Charlie Brooker’s Black Mirror (2015–2020) dress like us, and the dystopian technology they put up with is, for the most part, a technology that has existed for years. Armando Iannucci’s imagining of a space cruise for rich people in Avenue 5 (2020) overlaps with Elon Musk’s actual plans of sending wealthy tourists to the moon, while Albert Robida’s visionary téléphonoscope (1879) amounts to a sad reminder of our everyday Zoom call. Is not the current COVID-19 crisis the blueprint to the ultimate post-apocalyptic script? Spanish filmmaker Juan Antonio Bayona noted in a recent interview that Steve Soderbergh’s Contagion (2011), originally labeled as a sci-fi movie by IMDB, is now a drama according to the same internet portal. Science is not fiction anymore, which means at least two different things: that science has lost the power to convey the kind of awe that may be later turned into fiction, and that fiction seems to be unable to inspire a narrative of scientific or—broadly speaking—human progress. How can we retrieve the emancipatory value of progress in good old futuristic sci-fi when the future coincides with the present? What should cultural production look like to help us imagine an alternative to financial capitalism in the face of the impossibility of utopia? The answer, I will claim, resides in Franco Berardi’s concept of “futurability”. This paper explores the limits of this concept by reading side by side Javier Olivares’ and Pablo Olivares’ The Ministry of Time (2015) and Oriol Paulo’s Mirage (2018). Full article

Electrolytes based on ionic liquids (IL) are promising candidates to replace traditional liquid electrolytes in electrochemical systems, particularly in combination with carbon-based porous electrodes. Insight into the dynamics of such systems is imperative for tailoring electrochemical performance. In this work, 1-Methyl-1-propylpyrrolidinium bis(trifluoromethylsulfonyl)imide and 1-Hexyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide were studied in a carbon black (CB) host using spectrally resolved Carr-Purcell-Meiboom-Gill (CPMG) and 13-interval Pulsed Field Gradient Stimulated Echo (PFGSTE) Magic Angle Spinning Nuclear Magnetic Resonance (MAS-NMR). Data were processed using a sensitivity weighted Laplace inversion algorithm without non-negativity constraint. Previously found relations between the alkyl length and the aggregation behavior of pyrrolidinium-based cations were confirmed and characterized in more detail. For the IL in CB, a different aggregation behavior was found compared to the neat IL, adding the surface of a porous electrode as an additional parameter for the optimization of IL-based electrolytes. Finally, the suitability of MAS was assessed and critically discussed for investigations of this class of samples. Full article

Investigations that were carried out over the last two decades with novel and more sensitive instrumentation have dramatically improved our knowledge of the more violent physical processes taking place in galactic and extra-galactic Black-Holes, Neutron Stars, Supernova Remnants/Pulsar Wind Nebulae, and other regions of the Universe where relativistic acceleration processes are in place. In particular, simultaneous and/or combined observations with $\gamma$-ray satellites and ground based high-energy telescopes, have clarified the scenario of the mechanisms responsible for high energy photon emission by leptonic and hadronic accelerated particles in the presence of magnetic fields. Specifically, the European Space Agency INTEGRAL soft $\gamma$-ray observatory has detected more than 1000 sources in the soft $\gamma$-ray band, providing accurate positions, light curves and time resolved spectral data for them. Space observations with Fermi-LAT and observations that were carried out from the ground with H.E.S.S., MAGIC, VERITAS, and other telescopes sensitive in the GeV-TeV domain have, at the same time, provided evidence that a substantial fraction of the cosmic sources detected are emitting in the keV to TeV band via Synchrotron-Inverse Compton processes, in particular from stellar galactic BH systems as well as from distant black holes. In this work, employing a spatial cross correlation technique, we compare the INTEGRAL/IBIS and TeV all-sky data in search of secure or likely associations. Although this analysis is based on a subset of the INTEGRAL all-sky observations (1000 orbits), we find that there is a significant correlation: 39 objects (∼20% of the VHE $\gamma$-ray catalogue) show emission in both soft $\gamma$-ray and TeV wavebands. The full INTEGRAL database, now comprising almost 19 years of public data available, will represent an important legacy that will be useful for the Cherenkov Telescope Array (CTA) and other ground based large projects.

In this article, I consider the representation of African-Caribbean religions in the early horror adventure film from a postcolonial perspective. I do so by zooming in on Ouanga (1935), Obeah (1935), and Devil’s Daughter (1939), three low-budget horror productions filmed on location in Jamaica during the 1930s (and the only films shot on the island throughout that decade). First, I discuss the emergence of depictions of African-Caribbean religious practices of voodoo and obeah in popular Euro-American literature, and show how the zombie figure entered Euro-American empire cinema in the 1930s as a colonial expression of tropical savagery and jungle terror. Then, combining historical newspaper research with content analyses of these films, I present my exploration into the three low-budget horror films in two parts. The first part contains a discussion of Ouanga, the first sound film ever made in Jamaica and allegedly the first zombie film ever shot on location in the Caribbean. In this early horror adventure, which was made in the final year of the U.S. occupation of Haiti, zombies were portrayed as products of evil supernatural powers to be oppressed by colonial rule. In the second part, I review Obeah and The Devil’s Daughter, two horror adventure movies that merely portrayed African-Caribbean religion as primitive superstition. While Obeah was disturbingly set on a tropical island in the South Seas infested by voodoo practices and native cannibals, The Devil’s Daughter was authorized by the British Board of Censors to show black populations in Jamaica and elsewhere in the colonial world that African-Caribbean religions were both fraudulent and dangerous. Taking into account both the production and content of these movies, I show that these 1930s horror adventure films shot on location in Jamaica were rooted in a long colonial tradition of demonizing and terrorizing African-Caribbean religions—a tradition that lasts until today.

The effects of black ginseng, which has many kinds of biological activities, on dogs was investigated. Serum samples of beagle dogs, which were fed with black ginseng for 8 weeks, were measured using high-resolution magic angle spinning (HR-MAS) nuclear magnetic resonance (NMR) spectrometry. Acquired NMR data from the serum of dogs fed for 0, 4, and 8 weeks were analyzed by metabolic profiling and multivariate statistical analysis. In statistical analysis and biomarker analysis results of metabolite profiles, formate, glutamine, histidine, isoleucine, leucine, proline, and valine had variable importance in projection (VIP) scores above 1.0 and excellent area under the curve (AUC) values of receiver operating characteristic (ROC) curves above 0.9. In the result of multivariate statistical analysis, the score plot showed the discrimination between before and after feeding of black ginseng. These differences in metabolic profiles are considered to be due to the involvement of metabolic processes following black ginseng administration, such as enhancing immunity and energy metabolism. Through metabolomics analysis, we confirmed the biological efficacy of black ginseng in dogs and also confirmed that metabolomics can be applied to the pet health industry. Full article
