Still a Revolutionary …
No full textThe conversation below is a follow-up to Christopher Bigsby's interview with Amiri Baraka, published in Theatre Quarterly three decades ago, in 1978. It was recorded in the artist's backstage room in Katowice, Poland, immediately after a moving performance of the Amiri Baraka Speech Quartet in the Hipnoza Jazz Club in Katowice, during the ‘Ars Cameralis Silesiae Superioris’ Festival in 2009. The interlocutors were accompanied by a leading jazz pianist, Dave Burrell, and an excellent double bass player, William Parker. The interview, originally carried out for the Er(r)go: Journal of Theory, Culture and Literary Studies, was possible thanks to the help and encouragement of one of the most inspiring Polish contemporary poets, Bartek Majzel, an unswerving propagator of culture in Silesia and throughout Poland. Paweł Jędrzejko is an Assistant Professor at the University of Silesia in Katowice. He is the author of Liquidity and Existence: the Experience of the Land and the Sea in Herman Melville's Thought (Sosnowiec-Katowice-Zabrze: BananaArt.Pl/ExMachina/MStudio, 2008). He is also a co-founder and co-editor of the Review of International American Studies and regularly works with Er(r)go Quarterly.</jats:p
Glimpse of Tangkhul Tribes
No full textTangkhul is a Naga tribe living in the Indo-Myanmar border area occupying the Ukhrul district in Manipur, India and the Somra Tangkhul hills in Myanmar. Despite this international border, the Tangkhul have continued to regard them as one nation. the history of the Tangkhul Nagas were not written in the early days. Still then, history can be read and understood through oral conversation, songs and cultures of the people. The book explores various cultural and sociological aspects of the Tangkhul Naga tribe.

LeRoi Jones to Amiri Baraka: A Philosophical Journey of a Black Author
No full textThis text examines three early writings by LeRoi Jones/Amiri Baraka, a radical Black intellectual whose stance toward the role of African Americans within American society underwent a significant change in the early 1960s. He belongs to a generation of Black authors who began to publicly advocate the use of violence in the struggle for an overall improvement of the socioeconomic status of African Americans. Heavily influenced early on by the Beat Generation and liberalism of Greenwich Village, Baraka emerged in the sixties as perhaps the most powerful literary voice of Black intellectual circles in the United States. In particular three of his early texts – Blues People: Negro Music in White America, Dutchman and The System of Dante’s Hell – reflect his views of the African American situation in the context of the 1960s and are analyzed in this paper in terms of the intellectual transformation of Baraka from a mere advocate of Black culture to a militant Black Nationalist advocating a revolution against white supremacy
Antimicorbial Potency of Major Functional Foods’ Essential Oils in Liquid and Vapor Phases: A Short Review
No full textDue to the increasing risk of chemical contaminations in the application of synthetic fungicides, the use of plant essential oils and extracts has recently been increased. In the present review, the antimicrobial potential of the most active plant-food essential oils in liquid and vapor phases has been reviewed. The volatile isothiocyanates, aldehydes, and phenols, including allyl isothiocyanate, carvacrol, thymol, and eugenol, are considered to be the predominant components of essential oils, possessing significant antimicrobial activities. These components alone or in mixture can be effective. Overall, the antimicrobial activity of aroma compounds depends on the plant species, concentration, and method of application. This review provides useful information about the inhibitory application of the most common plant-foods’ essential oils in liquid and vapor phases against the growth of pathogenic microorganisms. Essential oils (EOs) are promising natural antimicrobial alternatives in food processing facilities. Although the food industry primarily uses spices and herbs to impart flavor, aroma, and pungency to foods, potent EOs represent interesting sources of natural products for food preservation

Identifying Effective Genes as Targets for RNA Interference in Sustainable Pest Control Strategies
No full textRNA interference (RNAi) is a powerful genetic tool that has revolutionized pest management by enabling targeted silencing of specific insect genes. By introducing double-stranded RNA (dsRNA) to target genes, RNAi can lead to phenotypic changes, reduced fitness, or even mortality in pest species, providing an alternative to chemical insecticides chemical insecticides. However, the efficacy of RNAi is highly variable across different insect orders and target genes. RNAi could target specific genes involved in an insect’s critical biological processes, such as growth, immunity, digestion, reproduction, and metabolism. This study reviews the potential of RNAi-based pest management strategies by focusing on key genes from various insect orders based on the significance of these orders in pest management, including Hemiptera, Neuroptera, Coleoptera, Diptera, Lepidoptera, and Hymenoptera. We address the variability in RNAi efficacy across different insect species, influenced by factors such as RNA degradation, delivery challenges, and organ-specific responses to gene silencing. Specifically, genes involved in cuticle formation, molting, chitin metabolism, immune response, and nervous system function are identified as prime candidates for RNAi-mediated pest control. For example, genes like chitin synthase, chitinase, acetylcholinesterase, and sex-determining genes show significant potential in reducing pest fitness, inducing mortality, and disrupting reproduction. Overall, this research provides valuable insights into the potential of RNAi as a species-specific and environmentally sustainable approach to pest control, laying the groundwork for developing innovative pest management tools that could reduce reliance on chemical insecticides
