Evaluation of Antimicrobial Properties of Linen Fabrics Dyed with Medicinal Herbal Extracts
No full textThe demand for sustainable and multifunctional textiles has driven research into natural dyeingusing medicinal herbs with antimicrobial properties. This study evaluates the antimicrobialefficacy of linen fabrics dyed with aqueous extracts, of neem (Azadirachta indica), tulsi(Ocimum sanctum), and turmeric (Curcuma longa). A total of 120 linen samples were dyedunder controlled conditions and tested against Staphylococcus aureus and Escherichia coli usingthe AATCC 100 quantitative method. Statistical analyses including one-way ANOVA andTukey's HSD test confirmed significant bacterial reduction confirmed significant bacterialreduction (>95%) for neem and tulsi, and moderate reduction (~89%) for turmeric. Expertevaluation via a detailed 25-item questionnaire (n=30) assessed aesthetic, functional, andmedical suitability. Results demonstrate the potential of herbal dyes as eco-friendly antimicrobialfinishes for linen textiles, with durability and safety suitable for medical and hygienicapplications
Statistical Analysis on Herbal Dye Extraction and Mordanting for Functional Cotton Textiles
No full textHerbal dyes offer a sustainable alternative to synthetic colorants, combining eco-friendliness with functional benefits such as antimicrobial, ultraviolet (UV) protective,and antioxidant properties. This study optimizes aqueous extraction and mordantingconditions for Dalbergia sissoo (Shisham) leaves and Solanum nigrum (Makoy) berries toenhance the performance of cotton fabrics. Extraction parameters temperature, pH,duration, and plant-to-water ratio were systematically varied to maximize yield, whilealum mordanting (pre- and post-dyeing, at multiple concentrations) was evaluated for itsinfluence on color strength (K/S), fastness, and bioactivity. S. nigrum achieved a higheryield (72%) than D. sissoo (65%) and demonstrated superior functional performance,including an Ultraviolet Protection Factor (UPF) of 135.8 (excellent protection) and 70%radical scavenging activity. Antibacterial assays revealed significant inhibition ofStaphylococcus aureus and Escherichia coli, with good retention after five launderingcycles. Both dyes enhanced UV protection, antioxidant capacity, and exhibitedacceptable wash and rub fastness. These results confirm the potential of S. nigrum and D.sissoo as viable natural dye sources for producing multifunctional, eco-friendly textiles,with particular applicability in medical, protective, and health-sensitive apparel sectors
Beyond the World as Picture:Worlding and Becoming the Whole World
No full textIn his well-known essay, Die Zeit des Weltbildes, Heidegger describes modernity as the age in which the world has been reduced to a picture. The conceptualization of the world as picture is the fundamental basis of globalization and the geopolitical relations of power, inequality and exploitation that characterize the world-system created by late capitalism. The world as picture is also the basis of various conceptual approaches for understanding worldliness informing various disciplines in the humanities and the narrative social sciences: world history, globality (global exchange and intercourse) and environmental kinship. But what is implied by the world as picture is the excess that is excluded or obscured by the picture frame because the idea of a frame intimates at something that lies beyond the picture that is its ontological condition of possibility. This talk examines two philosophical accounts of what is beyond the world as picture: Heidegger’s idea of worlding and Deleuze and Guattari’s idea of becoming the whole world as it is connected to their account of minor literature. It highlights the fundamental differences between these philosophies of world and the above approaches. Time permitting, I will then explore how postcolonial world literature, when read as part of the temporal process of worlding and world-creation, disrupts and shatters the world picture by participating in struggles within specific fields of forces in contemporary globalization. Such literature unsettles their readers’ sense of territorial boundaries and makes them aware of how they are constitutively implicated in the hierarchies of the contemporary world even as it resists being arrested in a geographically bounded and determinable subject-object such as a nation, a continent or a region. Pheng Cheah is Professor in the Department of Rhetoric at UC Berkeley. His research interests include late 18th-20th century continental philosophy and contemporary critical theory, postcolonial theory and anglophone postcolonial literatures, theories of nationalism, cosmopolitanism and globalization, philosophy and literature, legal philosophy, social and political thought, and feminist theory.

Perceptions of Undergraduate Medical Students towards Online Learning in a Medical College in the National Capital Region (NCR), India
No full textBackground: Since the COVID-19 pandemic hit the globe, it has not been possible to conduct traditional classroom teaching in view of the closure of schools and colleges in our country since March 2020. Hence, it is important to study the highlights, demerits, and bottlenecks in the implementation of online education from a student’s perspective. Methods: The present study was carried out to assess perceptions regarding virtual classroom among undergraduate students of a tertiary medical college in U.P. A pre-designed, semi-structured questionnaire was used. Study was conducted through an online survey. Data was analyzed with the help of SPSS version 21. Results: A total of 377 participants were included in the study. More than half of the participants (54.9%) preferred a mixed mode of learning which includes both online and offline learning. Lack of interaction with teachers (66.3%) and fellow students (57.6%) and lack of quiet space at home to listen to online classes (44%) were a few of the perceived demerits of online classes. Internet speed was found to be one of the most challenging issues faced in online learning (78.5%). Conclusion: Students’ perception of the blended learning mode was positive. They were, however, less enthusiastic about online learning than they were about conventional classroom learning
Long-term-survival phase cells of Salmonella enteritidis ATCC 13076 exhibit significantly greater tolerance to atmospheric cold plasma treatment of shell eggs
No full textThe main objective of this study was to evaluate the tolerance of stationary phase (STAT) and long-term survival phase (LTS) Salmonella Enteritidis ATCC 13076 to atmospheric cold plasma (ACP) in phosphate buffered saline (PBS, pH 7.0) and on shell eggs. Salmonella Enteritidis was cultured in tryptic soy broth supplemented with 0.6% (w/v) yeast extract (35°C) for 20 h (STAT) and 21 days (LTS). Cell morphology was determined by light microscopy. The PBS and shell eggs were inoculated with STAT or LTS cells to obtain ∼7.0 log10 CFU/mL or egg. The ACP was applied at 45 kV (PBS) and 60 kV (shell eggs) for 1–4 min and 1–5 min, respectively. Pathogen survivors were enumerated on thin agar layer (TAL) medium and on xylose lysine tergitol-4 (XLT-4) agar after 48 h of incubation (35°C). For survivors on shell eggs, R2 and mean square error values were obtained using Log-linear with Tail and Weibull models. The STAT cells were predominantly rod-shaped whereas LTS cells were coccoid. In PBS, reductions (log10 CFU/mL) of STAT cells were 1.0, 0.95, 1.45, and 1.44 after exposure to ACP for 1, 2, 3, and 4 min, respectively. In contrast, reductions in LTS cells were significantly lower (p 0.05). Additionally, there were no observed differences in shell strength and yolk color between ACP-treated and control eggs. Based on these results, LTS cells of S. Enteritidis are more tolerant to ACP than STAT cells and should be considered when developing process validation protocols involving application of ACP to inactivate Salmonella on shell eggs.This article is published as Barry K, Mendonça A, Phillips GJ, Boylston T, Fortes-Da-Silva P, Brehm-Stecher B, Juneja V and Wan Z (2024) Long-term-survival phase cells of Salmonella enteritidis ATCC 13076 exhibit significantly greater tolerance to atmospheric cold plasma treatment of shell eggs.
