 Abstract

This study presents the design and evaluation of Bacteria Induced Calcium Carbonate Precipitation (BICP) for self-healing concrete in high-rise buildings. Cracks in concrete compromise structural durability, safety, and increase maintenance costs, especially in inaccessible high-rise structures. BICP utilizes Bacillus subtilis bacteria capable of precipitating calcium carbonate (CaCO?) within cracks, restoring mechanical integrity and reducing permeability. Optimal bacterial concentrations were determined by varying cell counts (100 to 10? cells/ml) across M20, M25, and M30 concrete grades. Concrete mixes containing 10? cells/ml demonstrated significant improvements in compressive strength (25% for M20, 21% for M25, and 22% for M30), split tensile strength, flexural strength (up to 27.07%), ultrasonic pulse velocity, and reduced Cantabro loss by 15-25%. XRF analysis confirmed the formation of CaCO? precipitates within healed cracks, validating the self-healing mechanism. BICP offers a sustainable, long-term crack repair strategy, enhancing durability and reducing environmental impact in modern construction.

 Abstract

This paper will provide an integrative analysis of the role of the shortcomings in scope management in causing failure in Indian startup projects. The research is based on the large body of prior empirical, case-based, and theoretical research both on software project management and startup pivots and synthesizes that prior research and supplements it with a focused empirical research into the modern practice of startups in India. The study is a combination of systematic review of the literature on the topic and primary qualitative data collected on the basis of practitioners to create a contextualised model of scope-related failure modes. Primary results demonstrate that there are common faults in scope definition, stakeholder alignment, change control, and validation systems, and show ecosystem-specific stressors, such as resource constraints and investor pressures, that increase the impact of bad scope management. This paper ends by providing practical recommendations to founders, project managers, and investors, as well as defining the areas where it is still necessary to conduct more research.

 Abstract

Gastrointestinal disorders impose a substantial global health burden, characterized by disruptions in gut function and imbalances in the gut microbiome. Probiotics have emerged as promising bioagents for managing these disorders through modulating the gut microbiota. This comprehensive review thoroughly explores the role of probiotics in mitigating gastrointestinal disorders, emphasizing efficacy, safety, and future potentials. Amidst treatment challenges posed by chronic inflammatory conditions like ulcerative colitis and Crohn's disease, probiotics offer prospective solutions by influencing immune responses, preserving intestinal barrier integrity, and impeding tumor development. Clinical investigations validate probiotics' effectiveness in treating infectious and antibiotic-associated diarrhea in adults, alongside allergic disorders in children. Furthermore, bacteriocins derived from probiotics showcase efficacy in gastrointestinal ailment management. Nevertheless, uncertainties linger in probiotics' application for managing inflammatory bowel diseases (IBD), attributed to incongruous outcomes in experimental and clinical realms. This review critically assesses the current probiotics landscape, underscoring safety considerations and advocating for optimized formulations for enhanced outcomes. A profound comprehension of probiotic mechanisms stands pivotal for steering future research and therapeutic breakthroughs. Despite challenges, probiotics hold promise in alleviating the global burden of gastrointestinal maladies, necessitating persistent research to surmount obstacles and ensure their judicious, secure, and efficacious application.

 Abstract

Abstract The research evaluates how disinvestment affects workplace conditions in selected Indian Public Sector Undertakings (PSUs) through employee feedback and group dynamics analysis. A questionnaire consisting of 10 closed-ended questions was used to collect data from 96 employees of four important PSUs BHEL NTPC IOCL and Coal India Limited through quantitative research. The data collection process included both offline and online methods to increase participation from respondents. The research aims to explore both the connection between work environment health and employee teamwork and the effects of disinvestment on employee workplace perception in Indian public sector organizations. The data analysis utilized the independent t test method. The study shows that disinvestment creates noticeable effects on the way employees see their work environment which affects teamwork and organizational culture. The research shows that organizations must implement proactive HRM strategies to protect staff morale while building teamwork during economic reform disinvestment processes.

 Abstract

Chemistry very much contributed in the field of agriculture, medicines, industrial technologies, health sectors, pharmaceutical industries etc. Recently inorganic chemistry has gathered an enormous interest from the researchers worldwide. In recent years nitrogen containing five membered heterocyclic compounds are gained much more attention in the field of chemistry because efficiency in the catalytic activities, biological activities anti-microbial activities, anti-inflammatory activities, anti-viral activities, anti-cancer activities, anti-fungal activities, pyrazole, pyrazolones and pyrazolones derivatives are five membered heterocyclic compounds have attracted the attention of researchers due to their potent biological activities synthesis of various compounds based on the pyrazole and pyrazolone rings. Synthesized compounds were characterized using, FTIR, 'H-NHR, 13C-NMR, chemical analysis and mass spectra. These compounds shows activity against bacteria, fungi, virus etc. The anti-microbial activity of pyrazolone and pyrazolones derivatives shows much more attention of researchers in recent years for the welfare of human being.

 Abstract

This study examines the implementation and impact of the Reformed Teacher Observation Protocol (RTOP) at Shantiniketan School's primary section (grades 1-5) over two years (2023-2024). The research tracks the transformation of teaching practices from traditional methodologies toward more facilitative approaches using Understanding by Design (UbD) frameworks. Quantitative analysis of RTOP scores across 31 teachers reveals a significant overall improvement (mean score increase from 61.0 to 70.3), with the greatest gains in Classroom Culture domains. Despite progress, challenges persist in Procedural Knowledge and student-directed learning. The study identifies exemplary practitioners, teachers requiring intervention, and domain-specific trends. These findings contribute to the understanding of teacher development in constructivist educational settings and offer insights into effective professional development strategies for primary education transformation. The paper concludes with recommendations for sustaining and accelerating progress in pedagogical transformation.
