Introduction 
Sorghum bicolor L. Moench, commonly known as sorghum, has emerged as a significant and promising candidate for both sugar and lignocellulosic biofuel production. Cultivated sorghum varieties exhibit a wide range of phenotypic and morphological characteristics, and based on their intended use, they have been categorized into four distinct groups: grain, forage, energy, and sweet sorghum. Grain sorghum varieties typically stand between three to six feet in height, featuring large ear heads. Their primary role is to serve as a source of food for humans or livestock feed. These varieties play a crucial role in providing sustenance and nutrition to both people and animals. Sweet sorghum, also known as sweet stalk sorghum, represents a unique group of genotypes that accumulate soluble sugars within their stalks. These varieties can grow impressively tall, reaching up to twenty feet, and produce significantly higher biomass yields compared to grain sorghum (Murray et al., 2009). Sweet sorghum’s stems are characterized by their thickness and fleshiness, although they do tend to have relatively lower seed yields. Despite this, sweet sorghum offers substantial advantages in terms of bioethanol production due to the high sucrose content present in its stalks (Srinivasa Rao et al. 2009). It has garnered recognition as an ideal candidate for bioenergy crop cultivation in tropical and temperate regions around the world, particularly in the southern United States. When compared to other bioenergy crops such as corn, wheat, sugarcane, sugar beet, cassava, and sweet potatoes, sweet sorghum presents several noteworthy benefits (Disasa et al., 2016). It is notably drought-tolerant and requires significantly less water than many other crops, such as one-third of the water needed for sugarcane and half of that required for corn. Furthermore, it exhibits tolerance to salinity, enabling its cultivation in marginal regions that are not traditionally suitable for crop production. Additionally, sweet sorghum boasts lower greenhouse gas emissions on a life-cycle basis, contributing to a more sustainable and environmentally friendly biofuel production process. The applications of sweet sorghum are diverse, with its stalks being used for various purposes. In Brazil and India, the stalk is chewed fresh or processed for the production of food-grade syrup and alcohol. Its high sucrose content makes it an excellent candidate for bioethanol production, with the potential to yield up to 8,000 liters per hectare, surpassing the ethanol yield of corn by approximately twofold and outperforming

Aim: To determine the Efficiency Vs Load characteristics (External characteristics) of D.C. shunt motor Swinburne’s method.

This method is an indirect method of testing a DC machine. It is named after Sir James Swinburne. Swinburne’s test is the most commonly used and simplest method of testing of shunt and compound wound DC machines which have constant flux. In this test the efficiency of the machine at any load is pre-determined. We can run the machine as a motor or as a generator. The iron and friction losses are determined by measuring the input to the DC machine at no-load. The machine is to be run as a motor at normal voltage and speed. The Swinburne’s method includes all the losses in the field circuit and winding which do not occur actually in the machine but the error introduced due to this is quite insignificant and still shows the accurate results. In this method of testing no-load losses are measured separately and eventually we can determine the efficiency.

Surface: border strip, furrow, basin and check basin
Sub-surface
Micro-irrigation: drip, sprinkler; Pichter and bottle
Definition of Irrigation Method
Application of irrigation water to cropped field by different types of layouts is called as irrigation methods. The methods of irrigation initially might have been started to check the over flow of water from one field to another. But today, it has become necessary to save the water by proper methods to arrest run-off loss, percolation loss, evaporation loss etc., and to optimize the crop water need. Hence, irrigation method can be defined as the way in which the water is applied to the cropped field without much application and other losses, with an objective of applying water effectively to facilitate better environment for crop growth.
Factors Influencing Irrigation Methods
Soil type: The soil physical properties such as texture, structure, porosity, infiltration rate, etc. influence the selection of irrigation methods. Heavy texture soil restricts water movement than light texture soil wherein water move freely to deeper sections due to high porosity. Single grain structure soil allows water freely to move downward compared to other structures
Soil depth: If soil is shallow which holds less water, leveling and forming bunds etc. to hold? Maximum water is to increase the irrigation interval. Similarly if the soil is deep, it holds more water and needs longer irrigation interval. Accordingly, the irrigation methods can be selected.
Topography of land: In undulating topography, it is very difficult to adopt normal methods of irrigation. The slope of the land also decides the methods to be adopted. If the land is more sloppy, basin method cannot be used. In this condition strip method can be used. For undulating topography instead of strip or basin method, sprinkler or drip methods can be used.

Introduction 
A system approach to understand the soil-plant-water continuum fundamentally shifts our perspective from viewing these elements in isolation to recognizing them as an intricately woven, dynamic whole. It’s about appreciating that every change in one part of this natural tapestry—be it the soil, the plant, or the water itself—reverberates through the others, creating a cascade of interconnected effects. This holistic lens allows us to dissect the continuous exchange of water and energy, unraveling the complex feedback loops and emergent behaviors that characterize this vital agricultural system. Instead of merely tracking individual inputs and outputs, a systems view compels us to comprehend how these components influence each other over time, leading to a far more nuanced understanding of their collective behavior. At the heart of this continuum lie three primary, yet inseparable, components: the soil, the plant, and the water itself, all profoundly influenced by the atmosphere. The soil acts as both a foundational anchor and a dynamic reservoir. Its very composition—the proportion of sand, silt, and clay, its structure, and its organic matter content—dictates how readily water infiltrates, how much it can hold against the pull of gravity, and how quickly it can release water to plant roots. Processes like infiltration, percolation, and capillary rise describe water’s journey within the soil matrix, while evaporation from the soil surface represents a significant loss pathway. Crucially, the soil also serves as the medium for nutrient availability, with water acting as the solvent that transports these vital elements to the roots. The plant, in turn, is the primary biological conduit for water’s journey from the soil back to the atmosphere. It actively absorbs water through its roots, moving it upward through the xylem to the leaves, where it is transpired through tiny pores called stomata. This transpiration process is not merely a loss; it’s the driving force behind the plant’s physiological engine, facilitating

Introduction

Training is the crucial and expensive component of HRD, intended to improve the efficiency and effectiveness of performance of the members of organization through planned learning efforts, transfer of such learning at work place and in turn improvement of the organizational performance. Given such objectives, most of the training programmes fail to inculcate the transfer component in trainees (Subedi 2004). Hence, there is an increasing concern over training transfer at work place and the resultant improved organizational performance in terms of productivity, efficiency, effectiveness and turn over etc (Howard 1995, Huselid 1995, Martocchio and Baldwin 1997 and Salas et al.. 2000, Thayer1997).

Background and Technology Intervention

Tanks are one of the oldest structures in India that has been serving as an important water harvesting device since time immemorial. The total number of irrigation tanks in India is estimated to be around 2, 08,000 of which, three states in South India viz., Andhra Pradesh, Tamil Nadu and Karnataka accounts for nearly 1, 27,000 tanks irrigating 1.8 million hectares of land (Gandhiraj, 2009, Siva Subramanian, 2006, Sakthivadivel et al. 2004, Vaidhyanathan, 2001). In Tamil Nadu for instance, there are more than 39,000 tanks at present many of which were constructed during 18th and 19th centuries by kings, zamindars and Britishers (Jagadeesan, M 2011; Palanisami and Easter 2000: 9). Similarly in Telangana region of Andhra Pradesh, tank irrigation developed extensively since ancient times. The district of Warangal and Karim Nagar have several old irrigation tank structures.

The drones are configured to traverse the field and acquire photos and sensor data in alignment with the predetermined flight plan. High-resolution cameras get visual data, whereas multispectral sensors gather information on light wavelengths beyond the visible spectrum, thereby offering insights into plant health and stress levels.
During drone flights, essential techniques for data acquisition encompass photogrammetry utilizing overlapping high-resolution images, GPS tracking for accurate location data, IMU (Inertial Measurement Unit) sensors for monitoring attitude and movement, ground control points (GCPs) for precise georeferencing, multispectral or hyperspectral imaging for comprehensive spectral analysis, LiDAR scanning for the generation of 3D point clouds, and data logging systems to document sensor readings throughout the flight, all while meticulously planning flight paths and accounting for variables such as lighting and weather conditions.
Drones have emerged as a vital competitive advantage in the inspection of various asset types, optimizing time, reducing costs, and mitigating risk. Historically, an inspection necessitated an inspector to ascend the structure, capturing images and doing measurements manually from considerable heights.
This procedure is intricate; it necessitates extended hours and the presence of numerous experts on site for safety. The data generated by inspectors through manual pictures and measurements is limited: manual inspections may necessitate many trips to collect adequate information for necessary maintenance.
Manually operating a drone to obtain the data necessitates training, expertise, and extensive experience. A pilot collecting data for a tower inspection must comprehend the requirements of the inspectors. The pilot must comprehend how to maneuver an aircraft accurately around an asset to obtain precise aerial photos, regardless of barriers, wind conditions, or the necessity to replace batteries during the trip. The data must be examined and converted into a digital format that is

New techniques and approaches to groundwater studies are always in deep concern with the hydrogeomorphologists. The designing of new techniques or adapting existing techniques with better enhancement to solve practical problems in the study of groundwater are of central concern. One of the recent technical developments include the mathematical model of groundwater flow that has become the most widely used computer-based model in the groundwater industry. Techniques to identify and date recently recharged water that is useful in characterizing the susceptibility of hydrogeologic environments to contamination are utilized by various research groups all over the world.

Geophysical methods for determining the hydraulic properties of fractured rocks gained the importance in the hydrogeomorphic studies. Predicting the movement of water and contaminants through fractured rocks has been one of the most challenging problems in hydrogeomorphology. Besides conventional and above mentioned techniques the techniques discussed in this chapter are Remote Sensing, Geographical Informational system (GIS), Global Positioning System (GPS), Digital Elevation Model (DEM), Groundwater Information System (GWIS), Digital Surface Terrain Modelling (DSTM), Multicriteria evaluation (MCE) and Thermal Infra Red (TIR) Mapping and Microwave Data.

17.1 Introduction

It is well known fact that planners as well as end users have to consider any resources as technology from economic point of view. Therefore, it is important to have techno – economic analysis of each energy source option. In the feasibility study of particular energy option, three tier judgment approaches is required, which include technical feasibility, economical viability and social acceptability. Hence in the rural energy planning programme one has to considered techno socio economic analysis of an individual energy option. Since in integrated rural energy planning, locally available energy resources are used, presuming that it is socially recognized. Hence in the IREP project, the need and scope of techno economic analysis in terms of economic analysis of different technical feasible options, before between “economic” and “finical” analysis should be kept in mind. An economic analysis is needed to verify that a particular energy source will provide “net benefit” to society as a whole, before its final integration in the energy context, while a financial analysis integrated in the energy practices. In simple words, a financial analysis is concerned with goods and services, money inflow and outflows and the transfer of payments. An economic analysis also considers the social benefits and costs of goods and services which are not traded in a market.

1. Introduction 
The Techno-Economic Analysis (TEA) of nanotechnology-based microalgal biodiesel explores the intersection of nanotechnology and renewable energy production, aiming to assess the economic feasibility and sustainability of integrating nanomaterials into the microalgal biodiesel production process (BlancoCanqui, 2010). As the global demand for sustainable energy sources continues to rise, microalgae have emerged as a promising feedstock for biodiesel production due to their high lipid content and rapid growth rates. Nanotechnology offers innovative solutions to enhance various stages of the microalgal biodiesel production chain, from cultivation and harvesting to lipid extraction and conversion (Moustakas et al., 2020).This introduction provides an overview of the key objectives, methodologies, and implications of conducting a TEA on nanotechnology-based microalgal biodiesel. It outlines the significance of integrating nanomaterials into biodiesel production processes, highlights the potential benefits and challenges associated with nanotechnology adoption, and sets the stage for the subsequent analysis of economic factors and technical considerations (Borowitzka and Moheimani, 2013).The introduction also discusses the broader context of sustainable energy transition and the role of microalgal biodiesel as a renewable alternative to conventional fossil fuels (Gaurav et al., 2017). It emphasizes the importance of evaluating not only the technical feasibility but also the economic viability and environmental sustainability of nanotechnology-enabled biodiesel production methods. By conducting a comprehensive TEA, this study aims to provide valuable insights into the cost-effectiveness, scalability, and market potential of nanotechnology-based microalgal biodiesel, informing strategic decision-making and investment priorities in the renewable energy sector (Gouveia and Oliveira, 2009; McCollum et al., 2018). Through interdisciplinary collaboration and rigorous analysis, the TEA seeks to advance our understanding of the economic and technological factors shaping the future of sustainable biofuel production.

Nano-technology refers to technology on a nano- meter scale, specifically less than 100 nano-meters. The novel nano-particles are tiny spheres (fullerenes) or tubes (nanotubes) made from carbon atoms. It facilitates the development of future inventions transversely a vast array of fields. New nano-particles are being made of silicon, ceramic, polymers or even natural ingredients that break down in the body. The characteristics that make these particles functional in the food industry include optical properties, reactivity to temperature, and biodegradability. They can be used as probes or filled with flavorings or nutrients for delivery. Highlights on the categorisation of agriculture with nano- food technology and nutrition are given in Fig 1.

There are three key elements in nano-technology. They are: (1) substances at nano-scale exhibit novel physical and chemical phenomena with novel functions (2) allowing to measure, control and operate material at the nano-scale that transform them to functions. (3) allowing the union of nano scales of materials for exceptional properties.

5.1 Technology readiness levels- Introduction
Technology readiness levels (TRLs) is measurement of the maturity level of a particular technology. These are based on a scale from 1 to 9, with 9 being the most mature technology. It is a map that shows whether a given technology is in a conceptual state or can be used in real-world applications and ensures innovations are thoroughly tested before being applied on a large scale. The TRL scale uses a set of questions designed to measure progress of a technology toward maturity. They help in reducing risks and improving efficiency. TRLs were initially designed in the 1970s for use by NASA to assess how prepared a technology was for space missions. Technology for space travel is always extremely sophisticated and with a high degree of risk. NASA required a system to assess systematically whether or not a new technology was ready to implement. By breaking down development into different levels, NASA was able to provide informed decisions on which innovations were ready to incorporate (figure 12). In due course, TRL proved to be so effective that other industries began to use it. Other entities like the European Space Agency (ESA), U.S. Department of Defense (DoD), BIRAC, DRDO and many other agencies have taken , to using TRL to guide R&D strategies. TRL helps in simplifying development, decreasing risks, and maximizing resource utilization.

Technology Assessment and Refinement
What is Technology Assessment?
Technology assessment serves as a method or tool for forecasting future technological needs. It helps in envisioning or predicting potential technological developments required by users and in identifying areas where existing technologies can be improved. In agriculture, evaluating a technology means understanding its worth or effectiveness. This evaluation can be done by researchers, farmers, or other relevant stakeholders. The knowledge obtained from such evaluations is essential for creating new technologies, improving existing ones, and ensuring their successful adoption by end users.
The approach to technology assessment varies depending on who is conducting the evaluation, the purpose behind it, and the specific characteristics of the technology being assessed. It is commonly defined as the organized and intentional use of knowledge, skills, and experience to carry out a task or deliver a service that contributes to the well-being of society.
Technology Assessment: Definition and Objectives
According to Strasser (1972), technology assessment is a structured approach to planning and forecasting that identifies various options and associated costs. It considers not only economic factors but also environmental and social impacts, both internal and external to the technology being evaluated. The assessment places emphasis on analyzing both the positive and negative consequences of technologies. As such, institutions involved in the development, refinement, and dissemination of agricultural technologies have a significant stake in conducting technology assessments.

4.1 Introduction 
The growing recognition of biofuels as a competitive renewable energy source is increasingly evident, particularly when compared to the fossil fuel energy's limited supply, unstable geopolitical environment, and environmental repercussions associated with fossil fuel energy. In the broader context of renewable energy sources (RES), which are characterized as sustainable resources long-time availability at an affordable price and devoid of adverse effects, biofuels emerge as a promising category.(Charters, 2001) Biofuels include any type of energy-dense material that is either directly acquired from biological activities or is obtained through the chemical conversion of biomass from previous species.(Rodionova et al., 2017) Because biomass can be effectively converted into energy, biofuels play a crucial role in supplying energy needs and consumptions. The importance of biofuels in the global energy landscape is underscored by several factors, making them relevant technologies for both developing and industrialized countries.(Demirbas, 2007) Fuel, a concept central to energy discourse, encompasses substances that store and release energy when subjected to a chemical reaction. It serves as the lifeblood of energy systems, powering various sectors from transportation to electricity generation. The variety of fuels available is staggering; they include traditional petroleum-based fuels such as coal, oil, and natural gas, in addition to renewable energy resources like solar and wind and, most crucially, biofuels and alternative energy sources like nuclear power.(M et al., 2023) Within the realm of biofuels, there exists a multifaceted spectrum, where each type offers unique advantages and applications. Bioethanol, derived primarily from crops such as corn and sugarcane, stands out as a prominent example. Biodiesel, synthesized from vegetable oils or animal fats, represents another significant category. Additionally, advanced biofuels, produced through cutting-edge technologies like cellulosic ethanol and algae-based biofuels, showcase the ongoing innovation within the biofuel industry.(Vickram et al., 2023) There are a number of reasons why people choose biofuels over conventional fuels, but their favorable effects on the environment are the main one. Unlike fossil fuels, biofuels present a renewable and sustainable option, as they are derived from organic materials that could be replenished. This contrasts starkly with the finite nature of fossil fuel resources, which are not only depleting but also contribute to ecological degradation. Moreover, the instability in the geopolitical landscape surrounding fossil fuels, with its attendant economic and security implications, further accentuates the appeal of biofuels as a more secure and resilient energy source.(Lee, Clark and Devereaux, 2008) When

Basics of Technology Incubation
Technology incubation is a fascinating process that fosters the growth of innovative startups and businesses with high-potential technology. It provides a supportive environment and resources for early-stage companies to develop their ideas, validate their business models, and navigate the challenges of commercialization.
Here’s a breakdown of the key aspects of technology incubation: What happens in a technology incubation?
Pre-incubation: Startups with promising ideas can receive initial guidance and support to refine their concepts and develop a business plan.
Incubation: Selected startups gain access to shared office space, mentorship from experienced professionals, networking opportunities, and access to funding sources.
Post-incubation: Graduated startups continue to receive support in areas like marketing, legal advice, and investor relations as they scale their businesses.
Benefits of Technology Incubation
Reduced risks: Startups can test their ideas and validate their market potential before investing significant resources.
Access to resources: Incubators provide vital resources like office space, equipment, and software, reducing the financial burden on startups.

Technology Promotion
The activity of promoting the transfer of technology by creating opportunities, advertising and organizing technology events.
Promotion is a marketing tool, used as a strategy to communicate between the sellers and buyers. Through this, the seller tries to influence and convince the buyers to buy their products or services. It assists in spreading the word about the product or services or company to the people. The company uses this process to improve its public image. This technique of marketing creates an interest in the mindset of the customers and can also retain them as a loyal customer.
Promotion is a fundamental component of the marketing mix, which has 4 Ps:
1. Product (Warranty, features, variety, quality, design, packaging, brand name)
2. Price (List price, discounts, payment terms, credit)
3. Place (channels, coverage, Types of promotion locations, transportation, inventory)
4. Promotion (advertising, self-marketing/personal, sales promotion, public relations, direct marketing, trade shows, events).

The way technology is evolving, and the way it is changing our ways of living, why should we not be optimistic about technology. But then optimism comes tagged with pessimism. We aim for unfathomable optimum optimism. Technology is like water. It finds its open spaces. If it fills the available spaces more than it should, there is flood.

Future engineers and technologists are expected to appreciate, more than before, the human dimensions of technology. They are expected to have a grasp of the global issues. There is a need to understand the nuances of working in a culturally diverse space. According to some experts, good engineering designs should not be deprived of the benefits of a broad spectrum of life experiences, as adequate familiarisation with societal demands is essential for practical technological literacy.

Future engineers need to be better equipped to deal with people of diverse backgrounds, such as from social sciences, management, and communication. Some of the grand challenges that are enlisted, from an engineer’s point of view, are environment protection, hunger, energy and controlling the spread of the diseases. We need developers of responsible technologies and products.

We need managers to manage things, and at the same time we need adequate number of things to manage. There is a need to build faith in the public that engineers and technologists are sensitive to their concerns. One of the biggest responsibilities of the engineers and technologists is to keep themselves updated about professional developments and practices.

Countries, not only want exceptional scientists and engineers, but also people who are temperamentally innovators, and think they fit into their country’s core values. Many would say, prepare young minds and nurture future innovators.
