Water system is considered an Arti?cial usage of the water on the dirt utilizing various strategies like siphons, cylinders and showers. Typically, the requirement for water system shows up where the precipitation is unpredictable, in dry times, or where lack of hydration is customary. An excessive number of water system frameworks are accessible with various sorts as indicated by the Climate of the dirt. The water utilized in water system has numerous assets, like underground water, through wells or springs; the surface water, from lakes, streams; or other a few sources, for instance, the treated wastewater or desalinated seawater. In this way, farmers need to save and safeguard their Agriculture water sources by limiting the capability of diseases. Since with any groundwater extraction, clients of water system water should be mindful so as not to deplete groundwater out with a rate more prominent than it is being recovered. There are two strategies of current water system systems, the conventional water system procedures and the Smart water system philosophies. Water system is like surface water system, trickle water system and sprinkler water system. Later on, a few extreme and confounded issues will be met by inundated agriculture. An illustration of a signi?cant issue is the low efficiency of the water assets for water system. An important safe guess is that over 40% of the diverted water system water is spent before at the level of the ranch, either through profound permeation or at the surface spillover. Nonetheless, frequently these misfortunes address botched open doors for water, as they keep water from showing up at the downstream redirections. One of the most noticeable coming issues is the expansion of various water prerequisites assets, for example, manufactural and metropolitan requirements. These are utilized to give water assets a higher worth, so as a result, researchers favor concentrating entirely on rehearses with a high inefficient rate. s worldwide populace is expanding quickly, rural efficiency in drylands needs improvement to fulfill food security needs. Subsequently, taking on Precision water system approaches is a suitable choice to more readily use the accessible water assets and further develop water efficiency in drylands. Water shortage has become one of the basic issues and undermines the supportable improvement

Plant breeding is a revered custom that proceeds with the most common way of creating further developed plant cultivars, which traces all the way back to the beginning of agriculture . People started to observe levels of greatness among the plants in their fields not long after the underlying regulations of cereal grains, from which they put away the seeds of the best to develop new harvests. Early plant-reproducing advancements were the trailblazers to such simple choice methodologies. Individuals from the whole way across the world investigated and developed almost 7000 assortments of food plants during Breeding 1.0, which started quite a while back. Breeding stage 2.0 began in the late nineteenth and mid 20th hundreds of years when an inbreeding discouragement was found. During this time, many advances in plant breeding were made in the study of reproducing itself, like duplicated field preliminaries, controlled intersections, factual examinations, formal exploratory plans, crossover breeding, family-based appraisals of reproducing values, and exact yield estimation at scale (e.g., with Muldrow joins). Breeding 3.0 came to around a long time back, when sub-atomic markers and genomic information started to enhance phenotypic information. Breeding 4.0 is quickly drawing nearer, with immense omics information and the fast advancement of informatics innovations. Starting from the start of the plant breeding cycle, beginning from crop training, new methodologies interceded by various mechanical upheavals are being advanced in the science consistently to build the speed, exactness, and Precision in plant reproducing. In the previous 10 years, this science has proactively brought the green upheaval by creating semi-predominate, supplement responsive, and crossover cultivars. In any case, taking into account the populace development, diminishing arable land, and Climate changes, these have requested more exact, high throughput moves toward that can intervene to foster harvest cultivars at a more prominent speed, with higher exactness, and accuracy. In such manner, the field of Artificial brainpower has as of late arisen, which has been recommended to have unprecedented potential to help with breeding Climate versatile Precisionyields. Climate strong harvests keep up with or increment crop yields

The societal implications of nanotechnology are the potential benefits and challenges that the introduction of novelnanotechnological devices and materials may hold for society and human interaction. The term is sometimes expanded to also include nanotechnology’s health and environmental implications, but this article will only consider the social and political implications of nanotechnology.

As nanotechnology is an emerging field andmostof its applications are still speculative, there is much debate about what positive and negative effects that nanotechnology might have.

Beyond the toxicity risks to human health and the environment which are associated with first-generation nanomaterials, nanotechnology has broader societal implications and poses broader social challenges. Social scientistshave suggestedthatnanotechnology’s social issues should be understood and assessed not simply as “downstream” risks or impacts. Rather, the challenges should be factored into “upstream” research and decision making in order to ensure technology development that meets social objectives.

1. Introduction
Good Laboratory Practice (GLP) is a systematic quality system essential for
ensuring the reliability, consistency, and integrity of laboratory data, particularly when the findings are used for regulatory decision-making. GLP ensures that laboratory studies are conducted in a scientific manner, maintaining high standards of ethical practice, precision, and reproducibility, with a primary focus on ensuring public and environmental safety. Introduced by the U.S. Food and Drug Administration (FDA) in 1978, GLP gained global recognition through the Organisation for Economic Cooperation and Development (OECD), which established guidelines for its implementation. GLP principles are now widely adopted in regulatory testing for pharmaceuticals, chemicals, food safety, and environmental testing. The OECD’s guidance on GLP has been instrumental in developing standards across the globe, ensuring that test results are scientifically valid and can be accepted internationally. In Asia, particularly in India and other developing countries, GLP compliance has gained increasing importance as pharmaceutical, environmental, and chemical industries expand. Regulatory bodies in these regions have gradually aligned their standards with international norms to ensure their competitiveness in global markets. This chapter discusses the key SOPs necessary for GLP compliance and provides a regional perspective, focusing on India and other Asian nations, where GLP frameworks are evolving to meet international standards.
2. Objective of GLP
The overarching objective of GLP is to ensure that laboratory data is accurate, reliable, and reproducible across different studies. The scientific and regulatory communities rely on GLP to ensure that findings from preclinical studies and safety evaluations can be trusted and utilized for regulatory approval.
The key objectives of GLP include
• Accuracy and Integrity of Data: GLP ensures that every aspect of data collection, analysis, and reporting is conducted with integrity and accuracy, preventing errors or falsification that could affect regulatory decisions.

Aim

To study the levelling instruments

To practice the simple leveling

Leveling

Leveling is a method of surveying used for determination of the difference of elevations or levels of various points on the surface of the earth. The elevation of a point is its vertical distance above or below a reference level, called datum. Most commonly used datum is the mean sea level (M.S.L). Leveling is required to determine the undulations of the earth’s surface for topographic mapping. Leveling is needed for the design of highways, railways, canals, sewers, etc. Leveling is essential for the layout of construction projects, locating the excavation levels and for the control of various elevations in buildings, bridges, dams etc. The results of the leveling can be used to determine the catchment area, volume of the reservoir and the area submerged by a reservoir.

Aim

To identify different parts of prismatic compass and to know their functions.

To practice of taking the angular measurement.

Compass survey principle

Compass surveying is a branch of surveying in which directions of survey lines are determined with a compass and the lengths of the lines are measured with a chain or tape. In practice, the compass is generally used to run a traverse. In compass surveying, a traverse consists of a series of straight lines connected together to form an open or closed polygon as shown in Fig.44.1. The points A, B, C, D and E defining the ends of the traverse lines are called traverse station or traverse points. The lengths of the traverse lines are measured with a chain or tape. At each traverse station, where the traverse lines meet, the angle is measured with a compass.

Aim

To study the different materials used for chain survey

Theory

Chain surveying is the method of land surveying in which only linear measurements are made. This method of surveying quit simple and it requires only a chain, a tape, few ranging rods and few arrows. It is used for securing data for exact description, marking the boundaries of land and preparing the maps of the area to show various details. The term details mean a natural or man-made feature at the ground surface.

Aim

To draw the drying characteristic curve for given grain by thin layer drying.

To determine the drying constant, heat utilization factor and coefficient of performance.

Theory

Fluidized bed drying is a method of drying by keeping the material in fluidized/ floating condition inside a chamber by hot air. In this drying process higher rate of moisture migration takes place.

Greenhouse selection

Selection of greenhouse to be constructed is important as each type has its own merits and demerits. There are two common types of commercial greenhouses namely; (i) Freestanding (single span) and (ii) Ridge and furrow (gutter connected or multi-span). Multi-span structure permits economy in construction, heating and cooling but the single span gives flexibility as far as microclimate inside the greenhouse in concerned. The freestanding Quonset type is usually accommodates many growing situations but there height restrictions near the side walls. Another freestanding type is single gable greenhouse and its many variations. The ridge and furrow or gutter connected greenhouse are joined at the eave by a common gutter.

Rubber-roll Sheller consists of two rubber rolls rotating in opposite direction at different speeds. One of the roll is fixed while the other is adjustable to obtain desired clearance between them. The rolls are driven by mechanically. The adjustable roll normally runs about 25% slower than the fixed one. A feeder feeds paddy uniformly to the machine (Fig.27.1). Paddy is fed in thin layer through the clearance between two rubber rolls, rotating in opposite directions at different speed. Difference in speeds of the rolls develops a shearing force on grain surface results in the splitting, breaking and separating the husk from the grains. One part of the husk is subjected to shearing forces whereas the other part in contact with the slower roll is under compression and is thus subjected to breaking forces. Husking is done by the action of these forces. The clearance between them should be smaller than the mean thickness of paddy and may be adjusted subsequently by judging the shelling efficiency. If the gap between rolls is properly adjusted, it can shell up to 95% of paddy fed to it. At decreased gap excess pressure results more breakage of grain and can also cause coloring of shelled rice. During shelling the faster roll should have a peripheral speed of 10 -13 m/ s, while the slower roll 8-10 m/s.

3.1 Introduction

The concept of nanoscience was first described in 1959 by physicist Richard P. Feynman in a lecture to the American Physical Society and it was Japanese researcher Norio Taniguchi who coined the term nanotechnology in 1974 to describe precision engineering with tolerances of a micron or less. Eric Drexler in 1986 in his book Engines of Creation, brought nanotechnology into the public domain.

Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, high pressure carbon monoxide (HiPCO),andchemicalvapor deposition (CVD).Mostof these processes take place in vacuum or with process gases. CVD growth of CNTs can occur in vacuum or at atmospheric pressure. Large quantities of nanotubes can be synthesized by these methods; advances incatalysis and continuous growthprocessesare making CNTs more commercially viable.

Introduction

Application of edible coatings is promising to improve the quality and extend shelf life of fruits and vegetables (Lin et al., 2011). Chitosan, a versatile biopolymer derived from deacetylation of chitin had been widely applied in the fresh-keep field owing to its good biocompatibility, biodegradability, antibacterial activity and capacities to form film (Lin et al., 2011).

The most commonly used technique has been discussed and we have tried to generalize the type of particle that can be synthesized by each of these methods. Though it is not a rule that is applicable to all cases but it can be applied to most cases.

Polymerization Radical Polymerization

The polymerization could be a free radical polymerization or an atom transfer radical polymerization. The process of atom transfer radical polymerization (ATRP) is better than the free radical polymerization as control of molecular weight and size of the particle can be achieved. The coating of polymer on silica nanoparticles is generally done by ATRP. The surface of the silica particle is modified with a suitable initiator.

16.1 Introduction

The stabilization of ultra fine as nano-particles in suspension is very important for both controlling the particle size and for developing process based application of these suspensions to achieve a desired result. Generally, two approaches, namely, Top Down and Bottom-Up approaches are followed for the preparation of ultra fine or nano particles. In the Top-Down method, production starts from the micro-scale and the particles size is reduced to nano-size through repeated impact and collision in high-energy ball mills. However, controlling of size, morphology, surface properties and electrostatic charge is often difficult. In the Bottom-up approach, production of nano-particles starts with the individual atoms and building up to a nano-structure by chemical processes.

Solid state materials can exists in various forms namely:

1. Single crystals (preferred for authentic characterization of structure and physical properties)
2. Polycrystalline powders that are agglomerates of large number of crystallites and are used for characterization when single crystal cannot be easily obtained
3. Nanocrystalline or nanostructured materials that posses large surface area
4. Thin films that can be grown in the best crystalline form for many applications
5. Amorphous systems that have no long-range translational order

Introduction

Test of pollen viability (extent of pollen viability) is important in pollination experiments to ensure fertility/seed setting. It is also important in monitoring state of pollens during storage in ecological/ taxonomic studies as well as during research on pollen biochemistry, genetics, stigma interactions, and incompatibility studies. Pollen viability refers to the ability of pollen to accomplish post-pollination events to achieve fertilization. Pollen viability test has gained importance particularly in plant breeding and hybrid seed production experiments/ practices. In this chapter, you will be acquainted with the basics of pollen viability test. However, for more professional knowledge on the topic readers are suggested to refer specialized books.

Pollen Viability Test

It is important to know the extent of viability of pollens used in pollination experiment, in finding fertility of a plant of interest, to monitor state of pollen on storage, in ecological/taxonomic studies, as well as in research on biochemistry, genetics, stigma interaction, incompatibility assay, etc. of pollen. Several pollen viability tests have been developed time-to-time. It is recommended to initially use different tests for a given pollen type to find out the most appropriate method that provides reliable result on pollen viability. It is important to note that every procedure requires standardization of protocol according to the sample used. Following different tests are used for assessing pollen viability.

1. In-vitro Pollen Germination Test

It is a simple, speedy, and quantitative test for assessing pollen viability. In this method, a collection/sample of pollen is germinated in vitro and observed under microscope. The percentage of germinating pollens (producing pollen tube) after appropriate treatment and a given period of time is determined. The percentage provides an index of viability of the pollen sample.

Introduction

Seed is a living entity (mature ovule) consisting of a tiny plant in embryonic stage along with the stored food protected by an outer layer known as seed coat. Seed is an important biological input in agriculture, which is economically important for successful crop husbandry. Cotyledons serve as the source of nutrients (proteins, carbohydrates, and oils) that not only nurture the plant at the early developmental (seedling) stages of plant but also the vegetarian (heterotroph) organisms. Being one of the important inputs in agriculture, viability of seed needs to be assessed to know the germination percentage of seeds used to raise a crop. Since viability of seeds may deteriorate on storage depending on the storage conditions. Therefore, often it becomes important to test viability/germinability and vigour of seeds before being used for raising a crop or conducting an experiment. In this chapter, we briefly discuss about the different methods which can be used for testing the viability of seeds.

Seed Viability

Seed viability can be defined as the capability of the seed to germinate and produce a normal seedling within a specified period. In other words, seed viability indicates how many seeds in a lot are alive and could develop into plants under appropriate field conditions. It is very important that most of the stored seeds are capable of germinating when sown in a field. They must possess higher viability at the beginning of storage and maintain it over the storage. A seed with high initial viability survives longer in storage; however, the viability deteriorates slowly at first and then rapidly as the storage prolongs. It is important to know the duration of storage after which a considerable decline in viability occurs under given storage conditions so that to take necessary action to revive the seeds. Excessive deterioration in vianility of seeds may lead to loss of the seed/material/ germplasm.

UPOV aims to encourage the development of new varieties of plants for the benefit of society by codifying intellectual property for plant breeders.

Introduction 
The evolution of digital governance in the 21st century has significantly redefined how public institutions function, deliver services, and interact with citizens. This transformation, enabled and accelerated by Information and Communication Technologies (ICTs), is not merely technical, but deeply institutional, cultural, and political. As states move toward more digitized, networked, and citizen-responsive systems, drawing upon theoretical frameworks that help explain, interpret, and evaluate these complex dynamics becomes essential. Theories provide the conceptual scaffolding necessary for analyzing the design, implementation, outcomes, and unintended consequences of digital governance practices.
