Subject: Optimisation and implementation of an ANN-based model for adsorption of ferrous ion from groundwater using banana stem-derived activated carbon
Keywords: Activated carbon, adsorption, artificial neural network, banana stem, kinetics
Abstract: The present study examines the potential of banana
stem-derived activated carbon (ACBS) for removing
ferrous ions from groundwater, supported by artificial neural network modelling. Batch experiments
were conducted to evaluate adsorption performance.
Kinetic studies indicated that adsorption followed
Lagergren’s pseudo-order and intra-particle diffusion mechanisms, while equilibrium data fitted best
with the Langmuir isotherm, suggesting monolayer
adsorption. Thermodynamic analysis demonstrated
the process to be spontaneous and endothermic,
with positive entropy change indicating enhanced
disorder at the solid–solution interface. The artificial neural network (ANN) model effectively predicted
adsorption behaviour, achieving a mean squared error of 0.00173 for ACBS, confirming its reliability.

Subject: Optimising the resilience of wheat to a changing climate in North Kashmir, India
Keywords: Climate change, India, North Kashmir, phenology, sowing window, wheat.
Abstract: Three field experiments were conducted to assess the
performance of various spring wheat genotypes, viz.,
SKAU-101 (V1), SKAU-102 (V2) and Shalimar Wheat2 (V3). These genotypes were sown on different dates:
15 October (S1), 1 November (S2) and 15 November (S3)
during the 2020–2021 winter (rabi) season. Randomised
complete block design (RCBD) was employed for the
experimental setup in North Kashmir, India. This design facilitated a thorough examination of each genotype’s response to the different planting dates within
the specified agroecological context. The crops sown
on 15 October showed superior growth, phenology and
yield (4.01 t ha-1 for grain). The SKAU-102 variety required less time to reach various phenological stages,
matured 5–12 days earlier than the other two genotypes, and produced a higher yield; the highest yield
(4.4 t ha-1) was observed with the SKAU-102 genotype
when sown early (V2S1). Furthermore, climate change
trends in the region from 1980 to 2021 revealed statistically significant increases in maximum and minimum
temperatures at a rate of 0.02°C per year, accompanied by a decreasing trend in precipitation at a rate
of -4.53 mm per year, which, if they continue, can adversely affect wheat growth, development and yield.
Considering the ongoing climate changes and the findings from field experiments, it is advisable to sow the
wheat genotype SKAU-102 by 15 October to achieve the
earliest maturity and the highest yield, in contrast to
the typical sowing date of mid-November in the region.

Subject: Strengthening institutional resilience for radiation emergency management in India
Keywords: None
Abstract: India’s growing nuclear programme requires stronger preparedness for radiation emergencies. Current emergency
governance rests on two pillars: nuclear institutions under the Department of Atomic Energy, and the national disaster
management system led by the National Disaster Management Authority (NDMA). While both are established, gaps persist in statutory authority, technical–administrative coordination, plan integration, state-level readiness, inter-ministerial
mandates, and medical capacity. This commentary benchmarks India’s framework against U.S. and Japanese models, and
proposes reforms: strengthening nuclear legislature, establishing a permanent technical body, updating NDMA guidelines, harmonising institutions under unified command, and investing in health and technology. These measures would
embed interoperability and resilience, and align India with global best practices in radiation emergency management.

Abstract: The miniaturisation of electronic
devices involves primary technical
challenges due to the proximity of
conventional charge-based transistors to physical limits. The problems
of heat management and the limitations of information transfer speed are
driving researchers to explore alternative technologies. A potential solution to this problem is spintronics,
which leverages the combined charge
and spin characteristics of electrons,
offering non-volatility, higher data
processing rates, increased integration densities, and significantly lower
power consumption rates1
. This
revolutionary approach could transform the way we store and process
information in the new technology.

Subject: Automated ECG signal analysis for cardiac aahythmia detection-A Review
Keywords: ECG analysis,cardiovascular diseases, signal processing, machine learning
Abstract: Cardiovascular diseases are the primary reason for mortality worlwide. As per the World Heart Report 2023 by the World Heart Federation, it highlights the global burden of cardiovascular diseases ,nothing that CVDs accounted for 20.5 million deaths in 2021, nearly a third of all deaths worldwide. The rate of death can be delayed and may be prevented by efficiently analyzing the ECG (Electrocardiogram) signals at the early stage of the disease. Many traditional diagnostic methods rely on manual interpretation of ECG signals and also accurate detection of different parameters (like P,Q,R,S,T waveforms, QRS complex duration, R-peak, PR interval, and RR-interval) from the ECG signals (1).This study explores a detailed discussion and comparison of various ECG analysis techniques. The analysis summarizes the ECG extraction method, databases available for disease detection and classification , and performance measures analyzed by the researchers (2).Based on the reviewed literature, existing methods indicate that real-time ECG analysis holds strong potential for identifying heart-related conditions and improving early detection rates, which in turn supports timely medical intervention (3).The findings highlights the potential of automated ECG analysis in reducing diagnostic errors, optimizing healthcare efficinecy, and supporting real-time monitoring for patients. The reviewed works are not yet sufficient in terms of accuracy and reliability, and our aim is to overcome these gaps by employing efficient signal processing, robust feature extraction, and advanced machine learning techniques.

Subject: Artificial Intelligence in Agriculture : A comprehensive review of crop yield prediction, crop rotation optimization, and leaf disease detection
Keywords: Artificial inteligence,Machine learning,smart farming,sustainableagriculture
Abstract: Agriculture has always been the heart of India's economy, providing food and sustaining millions of families. But today, farmers face new challenges. Climate change has made rainfall unpredictable, soils are losing fertility, and traditional methods that once ensured steady harvests are no longer enough. Erratic monsoons, the heavy use of fertilizers, and falling productivity have made farming riskier than ever. To tackle these problems, farmers now need to combine their traditional knowledge with modern solutions. Tools powered by Artificial Intelligence (AI)and Machine Learning(ML)can check soil quality, forecast the weather, and even detect crop diseases at an early stage.with this information,farmers can decide which crops to grow,when to sow them,how much water to use through automated irrigation,and even estimate yields more accurately to reduce financial risks. This is not about replacing traditional farming wisdom-it's about enhancing it with innovation, by embracing AI and ML, Indian agriculture can become more efficient, resilient, and sustainable. As the nation moves forward, technology can strengths farming, protect farmer's livelihoods, and secure food for generations to come.

Abstract: In an era marked by rapid growth, technological progress, increasing environmental stress and conflict, sustainability has become more than an ideal-it is necessity. This keynote address explores the meaning, challenges, and opportunities of sustainability in the Indian and international context, emphasizing its role in education, research, innovation, and everyday life. This challenge poses many questions for us in exploring possibilities for balancing three vital pillars-People, Planet and Prosperity-and how India, as one of the fastest-growing yet most climate-vulnerable nations, must pursue development without depletion. Individual and community attitudes and colleges are change agents in creating community engaged transformative research, knowledge exchange policies and practices for eco-creating sustainable living and prosperity. Special focus is given to the role of universities and young people in this transformation. Campuses can serve as living laboratories for sustainable practices-through clean energy adoption, waste management, water conservation, and curriculum integgration. Along with this, attitudes, behavior and sell being of people are crucial for enabling and empowering a sustainable future. This presentation will explore how students and educators can act locally while thinking globally, aligning with the United Nations Sustainable Development Goals (UNSDGs).

Abstract: The western Ghats, a range of ancient hills, extend between 73°E and 77°E longitude (from the tip of peninsular India at Kanyakumari to Gujarat). The Western Ghats (WG) run parallel to the west coast of India, covering approximately 160,000 sq.km, which constitutes less than 5% of India's geographical extent. Numerous streams originate in the western ghats, which drain millions of hectares, ensuring water and food security for 245 million people and hence ae aptly known as the water tower of peninsular India (Ramachandra and Bharath,2019; Bharath et al, 2021). The region is endowed with diverse ecological regions depending on altitude, latitude, rainfall, and soil characteristics. The western Ghats are among the eight hottest hotspots of biodiversity and 36 global biodiversity hotspots with exceptional endemic flora and fauna. Natural forests of Western Ghats have been providing various goods and services and are endowed with species of 4,600 +flowering plants (38% endemics), 330 butterflies (11% endemics), 289 fishes (41% endemics) and 135 amphibians (75% endemics).The Western Ghats, gifted with enormous natural resources potential, and the mandate of sustainable development based on foundation of prudent management of ecosystems, is yet a reality. Various unplanned developmental programs, which are proclaimed to be functioning on sustainability principles, have only been disrupting the complex web o life, impacting ecosystems, and causing a decline in overall productivity ,including four major sector: forestry, fisheries, agriculture, and water(Ramachandra and Bharath,2019).The prevalence o barren hilltops, conversion of perennial streams to intermittent or seasonal streams, frequent floods and droughts, changes in water quality, soil erosion and sedimentation, the decline of endemic flora, and fauna ,etc. highlights the consequences of unplanned developmental activities with a huge loss to the original economy during the last century. The development goals need to be ecologically, economically, and socially sustainable, which can be achieved through the conservation and prudent management of ecosystems. Sustainability implies the equilibrium between society, ecosystem integrity, and the sustenance of natural resources. Water sustenance in streams and rivers depends on the integrity of the catchment (watershed), as vegetation helps in retarding the velocity of water by allowing impoundment and recharging of gorundwater through infiltration (Ramachandra et al..2020).As water moves in the terrestrial ecosystem, part of it is percolated (recharging groundwater resources and contributing to subsurface flow during post-monsoon seasons), while another fraction gets back to the atmosphere through evaporation and transpiration. Forests with native vegetation act as sponge by retaining and regulating water transfer between land and the atmosphere. The mechanism by which vegetation controls flow regime is dependent on various bio-physiographic characteristics, namely, type of vegetation, species composition, maturity, density, root density and depth, hydro-climatic condition, etc. Roots of vegetation help (i) in binding soil, (ii)improve soil structure by enhancing the stability of aggregates, which provide habitat for diverse microfauna and flora, leading to the higher porosity of the soil, thereby creating the conduit for infiltration through the soil. An undisturbed native forest has a consistent hydrologic regime with sustained flows during lean seasons.

Abstract: Grasses are one of the most widespread and ecologically significant groups of plants, playing a vital role in maintaining environmental balance and supporting human livelihoods (Li et al.,2022., Dimri et al)2024).Grasses also contribute to soil conservation, water cycling, and climate regulation, making them a crucial component of ecosystem services (Sinha et al., 2023).In addition to their ecological importance, grasses have significant economic and cultural values. Many grass species are staple food crops, providing sustenance for millions of people worldwide (Satapathy et al,2019a;Satapahy et al 2019b).Others are used for medicinal purposes ,handicrafts, and industrial applications (Mishra etal2022).In India, grasses such as rice, wheat, and millets are essential crops (Jain et al,2024), while others like lemongrass and cittronella grass are valued for their medicinal and aromatic properties (Shah et al.,2011; Sharma et al,2019).The importance of grasses extends beyond their economic and ecological significance, as they also hold cultural and spiritual values.

Keywords: None
Abstract: Bihar is entirely land-locked state, located in the eastern part of the country, and lying between 24°20`10"-27°31`15" and 83°1950"-88°17`40" E. It is bounded by Nepal in the north and by Jharkhand in the South. The state covers a total geographical area of 94.163 km2.The first exploration of plants in the state was done by Buchanan-Hamilton from 1809-1813.After 50 years of interval Anderson (1863) had collected plants in this region and published a checklist. However, significant taxonomic study was performed by Haines (1921-1925), in form of "The Botany of Bihar and Orissa" in six volumes.

Subject: Acrylamide copolymerized low formaldehyde thermosetting resin for particle board
Keywords: Acrylamide, UF resin,FTIR, Formaldehyde emission, bending strength etc.
Abstract: The decrease of formaldehyde emission in wood panel products is crucial, and it can be partially managed by modifying the resin. The perforator method (IS 13745:1993) was used to test the effeteness of adding acrylamide (1.5 to 3.5%) to reduce formaldehyde emission from wood particle board. The functional groups of the produced control UF resin, mechanically modified acrylamide urea formaldehyde resin(AUF) and during rection modified acrylamide urea formaldehyde resin (UFA) were identified by Fourier Transform Infra-red (FTIR).Indian standard 3087:2005has been used for determination of physical and mechanical characteristics.The results show that the static bending modulus of rupture (MOR) of the manufacture boards ranged from 20.89 to 29.32 N/mm2 of, and the modulus of elasticity (MOE) from 2986 to 3678 N/mm2, while internal board strength (IB)ranged from 0.43 to 0.52 N/mm2. As per the requirements of IS 3087 (2005), 1.5 %mechanically modified urea formaldehyde and 2.5%internally modified urea formaldehyde based agro composites yielded the best results for grade if particle boards with respect to static bending strength. From the studies, it was found that acrylamide addition (1.5% mechanically and 2.5% internally) reduce the formaldehyde emission content in the panel without affecting the mechanical qualities.
