Introduction

The procedure of making or building casting in the sand mould cavity or any other material is known as a foundry. This is the cheapest method of shaping the metal. Foundry exercise offers the technique of creating casting in moulds shaped in both sand or different material. A foundry is a manufacturing plant where castings are created by softening metal, emptying fluid metal into a shape, then, at that point, permitting it to harden. Regardless of whether we have not at any time been to a foundry or even know what one resembles, we are encircled by the metal castings. There is a decent possibility that we are perusing this under 10 feet from one.

Generative Artificial Intelligence (GenAI) is rapidly transforming education by changing how knowledge is created, delivered, assessed, and experienced. Unlike conventional digital technologies that primarily retrieve or process existing information, generative AI can produce new text, images, audio, code, explanations, questions, and other learning resources in response to user prompts. This chapter introduces the foundations of GenAI and traces its evolution within educational environments, from conventional digital learning systems to intelligent, adaptive, and personalized platforms. It examines the role of Large Language Models, Retrieval-Augmented Generation, Learning Management System integration, multimodal learning, adaptive assessment, and AI-supported instructional design. The chapter also considers evidence from educational implementations involving school, higher education, and other learner groups. Particular attention is given to student engagement, self-regulated learning, teacher productivity, accessibility, fairness, privacy, and governance. By establishing the technological and pedagogical foundations of GenAI, the chapter provides a framework for understanding its opportunities, limitations, and responsible integration into contemporary education

Introduction
Sustainability in the digital age represents a transformative approach to addressing the critical challenges of economic growth, environmental stewardship, and social equity. For India’s vision of “Viksit Bharat” (Developed India) by 2047, integrating sustainable practices within the digital transformation framework is pivotal. This foundation has three primary pillars: technological innovation, inclusive development, and environmental responsibility.
Role of Technological Innovation: Digital technologies have emerged as essential drivers of change, reshaping traditional methods of governance, education, healthcare, and industrial processes. Initiatives such as Digital India have laid the groundwork for building a robust digital infrastructure, empowering millions of Indians, especially in rural areas, with access to essential services. Artificial intelligence (AI), the Internet of Things (IoT), and blockchain technology are transforming industries by enabling smarter decision-making, improving resource efficiency, and promoting transparency. For instance, AI-powered systems are being used to optimize energy grids, reduce waste in supply chains, and monitor environmental conditions. These advancements directly contribute to sustainability by minimizing resource consumption and mitigating environmental degradation. IoT-enabled smart cities enhance urban planning, improve waste management systems, and facilitate efficient energy use. India’s Smart Cities Mission exemplifies the integration of such technologies, targeting sustainable urbanization to accommodate the growing population without overburdening the environment.

Foundation architectures provide the technological basis for modern artificial intelligence systems and enable models to generalize across diverse tasks and modalities. This chapter examines the evolution of neural architectures that ultimately led to the dominance of the Transformer in contemporary language and multimodal AI. It begins with early neural networks, convolutional neural networks and recurrent neural networks before introducing attention mechanisms and the Transformer architecture. Particular attention is given to the major components of Transformers, including self-attention, multi-head attention, positional encoding and feedforward layers. Encoder, decoder and encoder–decoder configurations are examined through influential models such as BERT and GPT. The chapter further considers Vision Transformers and CLIP, demonstrating the extension of Transformer principles beyond natural language processing. At the same time, limitations such as computational complexity, memory requirements and long-context processing are discussed. Alternative approaches, including state-space models such as Mamba, efficient attention mechanisms, hierarchical architectures and Mixture-of-Experts models, are also explored as promising directions for scalable, efficient and adaptive AI.

Community mobilization stands as one of the most powerful tools for social transformation and sustainable development. It represents the collective action of communities working together to address their challenges, harness their strengths, and create positive change from within. At its essence, community mobilization embodies the principle that lasting development must emerge from communities themselves rather than being imposed by external forces. This chapter explores the fundamental concepts, historical evolution, and practical aspects of community mobilization, providing a comprehensive foundation for understanding this critical approach to community development that has shaped societies across cultures and continents for millennia.

Introduction
The identification of crop varieties is crucial in improving agricultural productivity, ensuring quality control, and supporting breeding programs. The correct identification helps improve food security, conserve biodiversity, and manage pests and diseases. Traditionally, farmers were relying on visual traits and phenotypic characteristics, but these methods had their own limitations. Modern molecular techniques, such as DNA fingerprinting and genotyping, have revolutionized variety identification, rendering it both more accurate and efficient. This has allowed for early identification of varieties, assisting in the selection of desired traits and enhancement of crop resilience, thus contributing to more sustainable and productive agricultural practices (Azizi et al., 2021; Khan et al., 2024).
Importance of Crop Variety Identification in Agriculture
Crop variety identification remains one of the most important components in agriculture since it can improve crop production, enhance food security, and improve adaptability of the crops to diverse environmental conditions (Hasan et al., 2021). The major aspects related to correct identification of crop varieties include:
• Quality control and standardization: It is often to measure the quality of crops that could meet market demand, for optimum consumption, and for export.
• Biodiversity conservation: This helps to conserve native crop varieties and regards the preservation of genetic diversity that is key for breeding and in future agricultural resilience.
• Breeding program: It allows the identification of a variety for selecting traits such as disease resistance, drought tolerance, and yield potential for improving agricultural productivity through its effectiveness.
• Pest and disease management: It contributes to pest and disease management too since different crop varieties may express varying levels of resistance which also reflects in pest control strategy.
• Market preferences and economic value: This helps the farmers to supply some specific markets depending on the market demand of certain varieties so as to gain a profit (Hussain & Nisar, 2020; Sharma & Singh, 2021; Tazeb et al., 2018; Dheer et al., 2020; Jamali et al., 2019).

Introduction
Public Relations (PR) plays a crucial role in shaping an organization’s reputation and fostering mutual understanding between organizations and their publics. From managing reputations to establishing goodwill, PR functions as a bridge between entities and their publics, influencing perceptions, maintaining dialogue, and building trust. This chapter delves into the core concepts of public relations, examines related terms, and explores the historical evolution of PR, which helps us understand its role in contemporary society. This overview will help readers appreciate the strategic importance of PR in contemporary society and its relevance to various stakeholders.

A. Beejamruit
Beejamrit is an organic solution primarily used in seed treatment to promote better germination, protect against soil-borne diseases, and enhance plant growth. It is part of traditional agricultural practices in India and is commonly used in organic farming. he preparation of Beejamrit involves simple, locally available ingredients like cow dung, cow urine, lime, water, and a handful of
soil (often sourced from under a banyan tree). The process is straightforward: cow dung is soaked in water overnight, and the mixture is later combined with lime, cow urine, and soil to create the final solution. This solution is then used to coat seeds before planting, providing them with a protective layer that boosts germination and shields them from pathogens. Beejamrit is valued for its low cost and quick preparation compared to chemical treatments. It is rich in beneficial microorganisms that help improve soil health and support plant growth.
The preparation of Beejamrit, a traditional organic solution used for seed treatment, is simple and involves locally available ingredients. Here’s the  process:

Bhutan has developed the concept of Gross National Happiness (GNH) as a substitute for Gross Domestic Product (GDP). In this theory, GNH comprises spiritual and cultural values, including love of sport, music, dance and spiritual activities. This is a good departure from measuring happiness purely from the view point of money. I would like to elaborate on four pillars that are necessary to uphold sustainable human happiness.

Ecology

There is an increasing awareness of the need for adopting sustainable lifestyles which will not make a heavy demand on our life-support systems of land, water, biodiversity, forests, oceans and climate. In his book titled World on the Edge.1 Lester Brown has described how we still have time to prevent environmental and economic collapse. Recent calculations on the ecological footprint each one of us is leaving behind shows that our per capita consumption of natural resources is exceeding the biocapacity of our earth. Soon we will need two planets to meet the growing demand for land, water, forests and biodiversity. In this context, we should keep in view what Mahatma Gandhi said long ago:

Fourth-generation biofuels, also known as advanced liquid biofuels, represent a progression of biofuel production leveraging advanced technologies (Chiaramonti & Maniatis, 2020). They incorporate the concept of “carbon capture and storage (CCS)” at both the feedstock and processing levels. Utilizing non-competitive feedstocks like algal biomass, cellulosic materials, and genetically engineered microorganisms, 4G biofuels ensure renewable and sustainable production without relying on arable land or food crops. The feedstock is designed not only to enhance processing efficiency but also to capture more carbon dioxide as the crop grows. Thermochemical processing methods are coupled with CCS technologies, which direct the generated carbon dioxide into geological formations or storage areas such as depleted oil fields or mineral storage as carbonates (International Renewable Energy Agency [IRENA], 2021). Fourth-generation biofuels have the potential to significantly reduce greenhouse gas (GHG) emissions and can even achieve carbon neutrality or negativity compared to previous generations of biofuels. This concept aligns with the idea of “Bioenergy with Carbon Storage (BECS)” (Demirbas, 2010). These advanced biofuels are currently in the development and experimental stages, encompassing various applications related to technology, processing, and feedstock. The primary feedstock for fourth-generation biofuels production consists of genetically engineered high-yielding biomass with low lignin and cellulose contents, addressing the challenges encountered in second-generation biofuels production. Alternatively, metabolically engineered crop plants with lower lignin, high oil contents facilitate enhanced carbon capture capabilities, and improved cultivation, harvesting, and fermentation processes and can significantly enhance biofuels production (Dutta et al., 2014).

Disease is worldwide in distribution

Etiology

Pasteurella multocida, a gram negative non spore forming, non motile rods which stain bipolar.

Epizootiology

Most species of birds are infected. Turkeys are more susceptible than chickens, and older chickens are more vulnerable than young chickens. Geese and ducks of all ages are highly susceptible to fowl cholera. Survivors of fowl cholera outbreaks become carriers and are the reservoir of infection. P. multocida isolates of pigs are pathogenic to fowls. Spread of P. multocida in a flock is by feed and water contaminated with excretions. Crates, feed bags and utensils serve as a mechanical carrier of the organism.

Fowl pox is a slow spreading viral disease of chickens, turkeys and other birds characterized by cutaneous lesions on the un-feathered skin of the head, neck, legs and feet and/or by diphtheritic lesions in the upper digestive and respiratory tract. The disease is worldwide in distribution.

Occurrence

Among poultry chicken and turkey are more susceptible. Other birds include pigeons, canaries, psittacines and wild birds. Fowl pox has been reported from more than 200 species of birds. The incidence is severe in multiple age groups and intensive poultry farming areas.

Foxtail millet (Setaria italica) is one of the oldest cultivated millet with several varieties throughout the world with grains varying in colour from pale yellow, to gray, white and red. Archaeologists say that foxtail millet is so old that no wild plant of the species is known to exist today. Foxtail millet is known with several names in different parts of world and India (Table 1). Foxtail millet is thought to be native to China and is commonly cultivated in several regions of Africa, India, Russia, USA and Europe. It is an annual grass with erect and robust culms.

1. Introduction Millets, including foxtail millet (Setaria italica), are gaining popularity as “smart foods” due to their numerous benefits for the planet, consumers, and farmers (Anitha et al., 2021). Foxtail millet, classified as a major millet, belongs to the genus Setaria in the Poaceae family. It has a rich history, with archaeological remains dating back 7400-7935 years in northern China and cultivation in Europe around 4000 years ago (Lu et al., 2009). Foxtail millet is currently cultivated in 26 countries and stands as the secondhighest cultivated millet globally. It is a relatively short plant, growing up to 2-5 feet tall, and demonstrates high resistance to various stresses, both biotic and abiotic(Sharma and Niranjan, 2018). The crop’s short generation cycle of 5-8 weeks from planting to flowering, followed by 8-15 weeks to attain seed maturity, allows for harvesting within 75-90 days after plantation. Foxtail millet produces hundreds of seeds per inflorescence (Li et al., 2020).

1.1 Introduction Millets are the most ancient grains that have been cultivated since time immemorial and consumed as food, feed and pastures. Millets are considered nutraceuticals’ since they possess significantly higher nutritional qualities compared to other cereals. Millets are grown across the world for grains and human food due to their nutritional advantages and ability to withstand adversities. Millets are preferred over other grains due to their short life cycle, low input requirement and ensured production with in-built genetic tolerance for abiotic stresses. Major millets include Pearl millet (Pennisetum glaucum L.) and sorghum (Sorghum bicolor L.), while there are numerous minor millets classified as small millets. With an extent of over 0.87 lakh ha and a production of 0.66 kg ha-1, India is the world leader in small millet production (Maitra and Shankar, 2019). Small millets are primarily grown on rainfed uplands in arid and semi-arid climates with sub-optimal management. Following the green revolution due to extreme demands for food, the main focus in India was on the production of fine cereals mainly rice and wheat to overcome hunger and poverty, while millets became ignored grains. Furthermore, urbanization, increased affluence and dietary changes relegated millets to the status of poor man’s food. However, due to a re-evaluation of nutritious characteristics, millets have recently regained their lost prestige (Maitra, 2020).

Chromatography is one of the most effective technique for accurate, fast and convenient separation and identification of the components of a mixture. The method was developed by Russian botanist Mikhail Tswett (1906), described by Karl Runge (1855). Martin and Synage (1944) received Noble Prize for developing methodology of partition Chromatography.

Partition chromatography

Partition chromatogaphy is a system comprising of two physically distinguished components - a mobile component or phase and a stationary component or phase. A mixture of substances which are to be separated is placed on the system and separation takes place on the basis of difference in distribution of molecular species in two phases. Relative movement is a result of driving force and retarding effects.

Stationary phase is the sorbent, which may be liquid or paper or gel. If it is liquid then it is held stationary by adsorbing on a solid support or matrix. The mobile phase may be solvent or developer or a gas. Since the two phases are immiscible, the partitioning is defined as the distribution of solute in two immisicible phases which are in contact with one another. When a column is filled with the sorbent and solvent the two phases form a large number of theoretical plates. Each plate contains both the phases. Solutes in solution (mixture of substances to be separated) is layered on the top of the column and when it enters to the column it distributes in the two phases. The ratio of the concentration of a solute in two phases is called its partition coefficient. The resolution of solutes improves as the length of stationary phase increases.
