 Abstract

Phosphorus availability in soil is often limited due to its presence in insoluble forms, leading to reduced plant growth and productivity. Microbial phosphate solubilization presents a sustainable strategy to enhance phosphorus availability in soil. In this study, phosphate- solubilizing fungi were isolated from soil samples and evaluated using qualitative and quantitative assays. Fourteen fungal isolates were obtained and tentatively identified based on morphological characteristics, primarily belonging to the genera Aspergillus, Penicillium, and Fusarium. Screening on Pikovskaya's agar medium revealed phosphate solubilizing activity in only two isolates, which are identified as Aspergillus flavus and Aspergillus niger. Quantitative estimation in liquid medium supplemented with 0.5% tricalcium phosphate showed a time-dependent increase in soluble phosphate concentration, after seven days. Phosphate solubilization was associated with acidic pH conditions, suggesting organic acid-mediated dissolution. These findings highlight the strain-specific nature of phosphate solubilization and support the potential application of selected Aspergillus isolates in sustainable agriculture.

 Abstract

India, world's third-largest consumer of energy, is moving towards I a greener, sustainable energy landscape. Global climate obligations, lower dependency on fossil fuels, and the need to enhance energy security are the primary reasons for this shift. Green energy transition depends on critical minerals - key raw materials essential for the development of renewable energy technologies. Solar panels, wind turbines, electric vehicles (EVs) and energy storage systems use critical minerals. Over the past few decades, China has been the dominant country, exporting 60-70% of critical minerals to the world. This has made the world heavily dependent on China for critical minerals. To reduce dependency and aid the global supply chain, India has begun exploring these critical minerals to meet domestic and global demand as the world transitions to green energy.

 Abstract

The rapid growth of smart home Internet of Things (IoT) devices has increased the demand for intelligent, real-time data processing while operating under strict battery constraints. Edge Artificial Intelligence (Edge AI) enables local data processing on IoT devices, reducing latency and dependency on cloud infrastructures. However, continuous AI inference can significantly drain battery resources, limiting device lifetime and reliability. This paper proposes a Battery-Aware Edge AI framework for Energy-efficient smart home IoT devices. The framework dynamically adapts AI workloads based on a battery state, device usage patterns, and environmental context. By integrating battery-aware scheduling, lightweight machine learning models, and adaptive inference mechanisms, the proposed approach significantly reduces energy consumption while maintaining acceptable performance. Experimental evaluation using simulated smart home scenarios demonstrates improvements in battery lifetime, reduced power consumption, and efficient AI-driven decision-making. The proposed framework offers a practical solution for a sustainable and long-lasting smart home IoT systems.

 Abstract

Continuous Integration and Continuous Deployment (CI/CD) have transformed software development by enabling teams to deliver updates more quickly and frequently. However, as release cycles accelerate and application complexity increases, maintaining consistent software quality becomes more challenging. This paper presents an automated testing framework specifically designed for CI/CD environments, utilising the Robot Framework. The framework ensures dependable test execution and features structured failure analysis through a straightforward rule-based system that identifies and categories common issues, such as missing elements, timeouts, or assertion failures. It also provides actionable recommendations to minimise manual debugging. The framework was evaluated using real-world web applications, including a student management system and a grocery ordering platform. The project integrate seamlessly with tools like GitHub Actions and Jenkins, enhancing test maintainability. Experimental results demonstrated a 65% reduction in the time required to investigate failures compared to conventional setups.

 Abstract

Co?NiBaO? nanoparticles were successfully synthesized via a co-precipitation method under optimized conditions. Their structural and morphological features were comprehensively characterized using XRD, XPS, FTIR, FE-SEM, and EDS analyses, with particular attention to the influence of calcination temperature on crystallinity and morphology. UV-Vis absorption spectra displayed a characteristic peak at 495-496 nm and optical bandgap of approximately 3.29 eV, which was further supported by photoluminescence (PL) studies. The photocatalytic activity of the synthesized nanoparticles was evaluated for the degradation of Toluidine Blue (TB), Reactive Red 35 (RR), and Eosin Yellow (EY) under visible light irradiation. Systematic kinetic studies revealed optimal degradation efficiencies of 80-89% within 40-70 minutes. Scavenger experiments identified hydroxyl radicals and photogenerated holes (h?) as the predominant reactive species responsible for pollutant degradation into smaller, non-toxic intermediates. Moreover, the catalyst exhibited excellent reusability, retaining stable photocatalytic performance over four successive cycles. Based on these results, a plausible photocatalytic degradation mechanism has been proposed and discussed.

 Abstract

The trade and economic foundations laid by Shri Guru Ram Das Ji have evolved over centuries even their relevance continues in the present scenario and he offered profound teachings on trade and life through a spiritual lens in the Guru Granth Sahib. Shri Guru Ram Das Ji, the fourth Sikh Guru, played a fundamental role in the development of trade and business especially through the founding of the city of Amritsar and also creating an environment conducive to economic growth. His deliberate initiative not only laid the foundation for Amritsar's future prosperity but also ensured that it became a remarkable center of trade, commerce, and spirituality. The principles of commerce and community development established by Guru Ram Das Ji remain vital to the region's economy and beyond. His references to trade often use it as a metaphor for the spiritual journey, emphasizing ethical living, the importance of devotion, and the pursuit of true "profit"--which, in his view, is the union with God. He laid the foundation for the city of Amritsar, which later became a hub of economic, spiritual, and cultural activity. Therefore, I try to describe some key elements of the importance of trade legacy of Guru Ram Das Ji in today's context.

 Abstract

ABSTRACT: The concept of home is frequently defined as a place of residence, typically a house or stable location. Scholars across disciplines such as sociology, anthropology, history, human geography, and philosophy have examined this concept extensively. In the modern Anglo-European context, home is often associated with the family house, symbolising a formative "place of origin" and "return" (Mallet, 63). Postcolonial perspectives expand this understanding to encompass instability and memories shaped by nostalgia, sentiment, and trauma. Feminist writers of the 1970s and 1980s have identified the home as a site of oppression and patriarchal control. For many diaspora writers, home represents both longing and an irretrievable place. This paper investigates the concept of 'home' as it pertains to internal diaspora communities (IDPs) in the North-East, specifically evaluating whether home is best understood as a static place, a personal location, or an imagined space in Arupa Patangia Kalita's novel Felanee.

 Abstract

Transmission line protection plays a vital role in maintaining the stability, reliability, and safety of modern electrical power systems. This paper presents a detailed study and implementation of a Transmission Line Protection Demo Control Panel, designed to demonstrate the fundamental concepts and operational principles of power system protection. The proposed system enables the simulation of various transmission line faults and provides insight into protective relay operation, fault detection, and isolation mechanisms. The demo control panel incorporates key protection schemes including overcurrent protection, earth fault protection, and distance protection, supported by appropriate sensing, control, and tripping circuits. The paper systematically analyzes the theoretical and mathematical foundations of relay coordination and protection logic. Hardware architecture, control strategies, and functional performance of the system are discussed to reflect real-world transmission line behavior. Practical applications in engineering education, laboratory training, and skill development are highlighted. The paper also identifies existing challenges, safety considerations, and future scope for enhancement through the integration of digital relays, communication protocols, and intelligent monitoring systems. This work aims to serve as a practical reference for understanding and demonstrating transmission line protection in power system engineering.

 Abstract

Rising test anxiety levels among Indian JEE & NEET (Joint Entrance Exam & National Eligibility cum Entrance Exam) aspirants has become an alarming academic and mental health concern. This study aims to evaluate the effect of Preksha meditation (PM) on the test anxiety levels of 50 Senior Secondary students, with an average age of 17, preparing for JEE/NEET exam in an integrated school in Bangalore. The Westside Test Anxiety scale (WATS) was employed to identify students with anxiety impairment. Items of the scale, rated on 5 points Likert scale, cover self- assess anxiety impairment and cognition which can impair performance. With a pre-post experiment design, participants were asked to complete the test anxiety scale before and after the intervention of 1 month (6 days/week) of Preksha meditation-based module. The results demonstrated highly significant reduction in Test Anxiety scores. Paired 't' test showed statistically significant value t (49) = 4.21, p < 0.001 with a medium sized effect (Cohen's d= 0.60). Gender-wise analysis revealed large effect among girls (Cohen's d= 0.83) and a small-moderate effect among boys (Cohen's d= 0.43), suggesting that the intervention was beneficial across both groups. The significant improvement observed in the study indicates the value of incorporating PM techniques into students' daily routines, especially during crucial life stages when academic performance in competitive examinations shapes future career trajectories.C
