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.

While conventional agromet advisories have played a crucial role in informing agricultural practices, their inherent broad-scale nature often falls short of addressing the nuanced realities of modern farming. For instance, rainfall predictions at a district level can mask significant variations at the farm or even field level due to local topography, soil types, and microclimatic conditions. Similarly, generic recommendations for irrigation scheduling or fertilizer application may not align with the specific needs of different crop varieties, growth stages, or soil moisture retention capacities within a farm. This lack of granularity can lead to inefficient resource utilization, sub-optimal application of inputs, and increased vulnerability to localized weather events, ultimately impacting productivity and profitability.
9.1. Key Drivers for the Emergence of PAAS
Several converging factors are propelling the shift towards precision in agrometeorology:
• Escalating Climate Variability: The increasing frequency and intensity of extreme weather events, coupled with long-term shifts in climate patterns, demand more adaptive and localized strategies. Farmers need precise and timely information to make informed decisions in the face of unpredictable weather.
• The Imperative for Sustainability: Sustainable agricultural practices necessitate the efficient use of resources like water, fertilizers, and pesticides. PAAS can contribute significantly by providing targeted recommendations that minimize waste and environmental impact.
• Technological Advancements: The rapid development and increasing affordability of various technologies are making PAAS a reality. These include:
• Remote Sensing: Satellite and drone-based imagery provide highresolution spatial data on crop health, soil moisture, and other critical parameters.
• Internet of Things (IoT) Sensors: Networks of sensors deployed in fields can continuously monitor local weather conditions, soil properties, and plant physiological parameters.

Introduction

Leafhoppers belong to the family Cicadellidae and constitute one of the largest families in the exopterygotan Hexapoda. Recent estimates of species for the world range between 35,000-45,000 species though little over 22,600 species are now described (Dietrich, 2004a). The leafhoppers belong to the order Hemiptera and suborder Auchenorrhyncha.
 
Leafhoppers can readily be recognized from other members of the Auchenorrhyncha by the presence of two or more rows of spines on hind tibiae and by the pronotum not extending back over abdomen. Their close relative, the Membracidae, have pronotum extending back over the abdomen. From planthoppers (Delphacidae) with which they are often confused, they can be recognized by the position and structure of antennae. The leafhopper antennae are placed between eyes compared to beneath the eyes in planthoppers; the second segment of the antenna (pedicel) is small without externally visible sensillae in leafhoppers compared to enlarged pedicel with prominent sensillae in the planthoppers. The movable large spur at the apex of hind tibia in plant hoppers is absent in the leafhoppers.

7.1 INTRODUCTION

Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant. In the budding process, a bud is taken from one plant and grown on another. The practice of grafting can be traced back 4,000 years to ancient China and Mesopotamia. As early as 2,000 years ago, people recognized the incompatibility problems that may occur when grafting olives and other fruiting trees.

7.2 ROOT STOCK

The part of the graft that provides root system to the grafted plant is known as rootstock. It is, normally, raised by seeds in the seedbed and then, transplanted in the nursery bed for budding and grafting. Rootstocks are also raised in pots and polythene bags.

Introduction
The haematological system, essential for sustaining life and comprising blood and its components, is fundamental to human and animal physiology. Blood is a unique connective tissue that performs several critical functions, including transporting oxygen, nutrients, and hormones to cells and removing metabolic wastes. It also plays a pivotal role in immune response, haemostasis, and the regulation of body temperature and pH. This
section provides an in-depth overview of the clinical physiology of the haematological system, covering the composition of blood, haematopoiesis, haemostasis, and common haematological disorders. Blood is composed of two main elements: plasma and blood cells. Plasma, the liquid component, constitutes approximately 55% of blood volume and consists predominantly of water, electrolytes, proteins, waste products, and dissolved gases. Plasma is the medium for transporting nutrients, gases, hormones, and waste products throughout the body. It contains important proteins such as albumin, which maintains osmotic pressure; globulins, which are involved in immune responses; and fibrinogen, which is crucial for blood clotting. The blood cells include erythrocytes (red blood cells), leukocytes (white blood cells), and platelets. Erythrocytes are the most abundant cells in the blood, with the primary function of transporting oxygen from the lungs to tissues and carbon dioxide from tissues back to the lungs. This is facilitated by haemoglobin, an iron-containing protein within erythrocytes that binds to oxygen. The lifespan of an erythrocyte is approximately 120 days, after which it is phagocytosed by macrophages, which are a type of myeloid phagocytic cells in the spleen and liver. Leukocytes are integral to the immune system, protecting the body against infections and foreign pathogens. They are categorized into granulocytes (neutrophils, eosinophils, and basophils) and agranulocytes (lymphocytes and monocytes).

6.1 Introduction
One of the various fusion welding techniques used to combine metals is arc welding. It melts and joins metals by producing a high temperature using an electric arc. An electric arc is created between a base metal and a consumable or non-consumable electrodede by a power source. The types of arc welding methods are listed below.
i. Gas shield tungsten arc welding
ii. Metal arc welding
iii. Submerged arc welding
iv. Gas shield metal arc welding
v. Flux Cored Arc Welding (FCAW)
vi. Electrode-Slag Welding (ESW)
vii. Electrode-Gas Welding (EGW)
viii. Arc Stud Welding (SW)
ix. Carbon Arc Welding (CAW)
x. Atomic Hydrogen Welding (AHW)
6.2 Gas Shield Tungstan arc Welding
An electric arc formed between a tungsten electrodede and the metal that needs to be joined starts the welding process. The arc melts the metal while protecting the weld from airborne impurities with a cloud of argon, helium gas, or carbon dioxide. A separate filler rod can be used to add additional filler metal. An inert gas, such as argon or helium, surrounds a non-consumable tungsten electrodede during the arc welding method known as tungsten inert gas welding (TIG). If more weld metal is needed, an additional filler rod can supply it. To prevent overheating and excessive erosion of the tungsten electrodede, a direct current is employed with the electrodede negatively charged.

Feeding of green and succulent fodder is of utmost importance to farm animals. Grazing fresh forage year round at the optimal stage of maturity would supply the highest quality and most palatable form of feed in any livestock operation. In most part of the world, green fodder is limited to a particular season only. Because of fluctuations in seasonal growth and plant maturity, excessive biomass in the spring, it is necessary to harvest and store forages to maximize both quality and productivity. One of the important form of conservation practiced on a wide scale is hay making. Hay making is an art in which the fodder is kept for future use in lean period. Since it contains large quantity of moisture it is to be dried properly to increase its keeping quality without reducing its nutritive value. The objective of hay making is to achieve a rapid moisture loss after cutting so that the forage can be romoved from the field with minimum losses from weathering and microbial degradation (Bareebam, 1992).

Introduction

Community-based fisheries management (CBFM), in which a community takes responsibility for managing its adjacent livelihood habitats with government or third-party assistance, can take both aquatic and terrestrial forms. CBFM plays an important role in managing aquatic ecosystems, fisheries, and communities using either traditional or scientific methods. If something bad happens, the locals take immediate action and deal with it in a systematic manner.

Guava, Psidium guajava Linn. was originated in tropical America and is presently cultivated in the tropical and subtropical world (Al-Fwaeer, 2013). It is considered one of the healthiest fruit because it has many medicinal properties. Right from strengthening our immune system to regulating a healthy and ideal blood pressure, Guava provides multiple health benefits. It is one of the richest sources of Vitamin C, minerals, dietary fiber and fulfills about 20% of our daily folate (Vitamin-B9) requirement which is not produced in our body and is essential for DNA repair and synthesis (Kevat, 2013). But its steady production is hampered due to a number of biotic and abiotic stresses. Amongst the biotic stresses, insect pests contribute to the maximum strength for declining its production.

Potted Plants

In urban areas, scarcity of space compels the dwellers to take up gardening on rooftop, terrace, balcony or small space adjacent to the house. Usually, plants are grown in pots or containers for rooftop gardening. Big size pots with diameter of 30 cm or more are required for growing rose plant. It is necessary to prefer tall pots to obtain appropriate growth of the plant having deeper root system. Now-a-days, pots of different materials such as clay, cement and plastic are used for growing potted plants. Usually, clay pots are better than plastic pots as clay is slow in transfer of heat thereby maintaining the root zone cooler. Of course, plastic pots are lighter and suitable for use on the rooftop as those put less load on the building structure. Light coloured plastic is preferred to dark colour as those generate less heat. Although heavier, cemented pots are more durable than earthen or plastic pots. The pots should have adequate drainage facility with holes in the bottom. Besides, a layer of gravel or medium-size stone of one-inch thickness are to be placed at the bottom of the container to facilitate drainage.

Introduction: Relation between transportation and meat quality
One of the fundamental aims of animal production system is to ensure better quality meat. Apart from various animal husbandry practices that affect the meat quality, the transportation of meat animals from farm to slaughterhouse and their handling at lairage, affect the meat quality greatly. For better meat quality, the pH of the meat should fall from normal pH 7.0 - 7.2 in live animal to pH 5.5 (ultimate pH) after slaughter at the onset of rigor-mortis. The low muscle pH is required to inhibit the microbial growth and meat tenderization (cathepsins system is activated at low pH). The ultimate muscle pH is achieved through the accumulation of lactic acid which is produced as a result of anaerobic glycolysis of glycogen. After slaughter, as the oxygen supply to muscle ceases, ATP is generated through anaerobic glycolysis of glycogen and in this process lactic acid is produced. ATP is required to keep the muscle in relaxed stage. This anaerobic glycolysis carries on till the glycogen reserve is exhausted. So, higher the glycogen reserve at the time of slaughter, longer the length of time duration of anaerobic glycolysis and higher the quantity of lactic acid production and greater the reduction of muscle pH. Hence, livestock should be transported and handled before slaughter carefully because stress during transit and in lairage could severely deplete the glycogen reserve of livestock.
The following facts should be especially taken care by the farmers raising livestocks for meat
1. Housing arrangement and design
• Any flaws/deficiencies in design, layout, cubicle size and its design, drainage, water bowls, slats, air circulation, etc. should be rectified

Blackrot of Cabbage

Economic Importance

Blackrot is an important bacterial disease of cabbage and other crucifer crops worldwide. The disease was first described in New York on turnips in 1893, and has been a common problem for growers for over 100 years (Smart and Lang, 2013). Blackrot has been given many names such as bacterial blight,black stem, black vein, stem rot or stump rot (Pfeufer and Davis, 2019). These pathogen is particularly damaging to cabbage and cauliflower, but turnip, rutabaga, collard, kohlrabi and Chinese cabbage are also susceptible. Broccoli and radish aregenerally resistant to Blackrot (Flynn,1999).

Artificial intelligence offers practical solutions to agricultural problems associated with population growth, food demand, climate change and limited natural resources. This chapter introduces machine learning, deep learning, computer vision and natural language processing, together with enabling technologies such as IoT, remote sensing and cloud computing. It explains their applications in crop monitoring, disease recognition, yield forecasting, irrigation, soil assessment and livestock management. AI can improve decision-making, resource efficiency, automation and precision farming while reducing reliance on manual labour. The chapter also examines adoption barriers, including high costs, limited digital literacy, data-security concerns and weak rural infrastructure, and considers future developments in autonomous and climate-resilient farming.

Injectable Anesthesia

Injectable anesthetics are the agents which are administered to the patient parentrally. They include drugs which are given intravenously to rapidly induce anesthesia in a patient. Single or combinations of drugs usually administered intramuscularly to patients which are difficult to handle. Injectable agents generally require less equipment and are easier to administer than inhalation anesthetics, but it must be remembered that once they are given to a patient they cannot be removed.

8.1 Introduction

After deciding the optimum size of farm pond and its dimensions, the next step begins the construction of farm pond. Further the site selection and location of the pond in the selected site to be finished before the construction of pond starts. The selection of site and location of farm pond areas have been discussed in Chapter 3. In this chapter, discussion on methodologies for construction of farm pond including spillways, inlet and outlet structures, design of grassed waterways and embankment have been presented. As a guiding principle, the construction of farm pond involves the following steps:

8.2 Site Clearing

The area where the pond is to be constructed has to be inspected first. The site where pond has to be dug out should be cleared to an extent of about 10 m from all sides of top dimensions of the pond. All bushes, shrubs, stumps and other unwanted materials should be dug out and removed. If there are roots of plants, they should be uprooted. The land may be ploughed and harrowed, if necessary, to get a more or less even topography.

To fully harness the potential of human creativity in industrial applications, it’s essential to safeguard and organize it effectively. One of the best ways to achieve this is by obtaining a patent. The term “patent” is derived from the Latin word “patere,” meaning “to lay open” or make available for public inspection. A patent is an exclusive right granted by the government to an inventor/creator for a limited time in exchange for disclosing their invention for public use. With this right, the patent holder can prevent others from making, using, selling, or exploiting the invention for a certain period, thereby providing commercial benefits to the inventor.

Patents are among the oldest forms of intellectual property rights and are territorial in nature, offering protection only within the country where they are granted. However, through conventions and the Patent Cooperation Treaty (PCT), applicants can seek protection in multiple countries. Obtaining a patent grants the inventor a monopoly right to control the product’s production, sale, and marketing. Although the rights granted through a patent are limited to a specific country, extending protection to all contracting countries is possible through a PCT application.

Introduction
The term “drug delivery systems” (DDSs) describes sophisticated dose forms that are utilized in the management of illness. The idea behind the design is to deliver the right quantity of medication to the diseased locations at the right time in order to maximize therapeutic efficacy while minimizing negative effects. The “3R” delivery principle—right dose, right place, and right time—is a concise way to describe it. Drug delivery technology can increase a candidate’s draggability while also enhancing the potency and safety of the medication. For example, liposomal drug delivery methods can be used to address issues with poor solubility and significant side toxicity in a variety of medications. The hazardous side effects of conventional chemotherapy medications can be greatly decreased by employing liposomal technology, which increases patient compliance (Andresen et al., 2004). Liposomes are the most widely used and researched nanocarrier for targeted medication delivery. They have improved therapies for a range of biomedical applications by stabilizing medicinal molecules, eliminating obstacles to cellular and tissue absorption, and boosting the biodistribution of compounds to specific locations in vivo. One or more concentric lipid bilayers enclosing discrete aqueous zones are described as the features of phospholipid vesicles, also known as liposomes. Due to the unique ability of liposomal systems to ensnape both lipophilic and hydrophilic molecules, a broad range of pharmaceuticals can be stored within these vesicles. Hydrophilic molecules may become trapped in the aqueous center of the bilayer membrane when hydrophobic molecules are introduced into it (Antohe et al., 2004).
There are many potentials uses for liposomes, and some recent reviews have offered useful details. In order to address the ongoing demand for the R&D of novel liposomal medications, significant efforts must be done. There are still some unanswered questions in this field. This article will summarize technological advancements, address issues, and explore the future of pharmaceutical liposomal delivery by focusing on three key areas: effective application, overcoming obstacles, and the move from idea to clinical application (Allen et al., 2013). Additionally, because of the large aqueous center and biocompatible lipid exterior, a variety of macromolecules, including as DNA, proteins, and imaging agents, can be administered.
Liposomes are a drug delivery technique that have several advantages, including biocompatibility, the capability to self-assemble, a large drug payload, and a range of physicochemical and biophysical properties that may be modified to control their biological features (Allen, 1994).
Among the features that characterize liposomal formulations and ascertain their durability in vitro and in vivo are particle size, charge, lamellar number, lipid content, and surface modification with polymers and ligands. Encapsulated compounds are protected from dilution, degradation, and early inactivation in the circulation by liposomes. Liposomes are generally believed to be low toxicity and pharmacologically inactive because they are frequently composed of phospholipids that occur naturally. But more and more studies are showing that liposomes are not as immunologically inactive as was once thought. Although liposomal formulations have demonstrated efficacy in vivo, their clinical translation has been gradual. The advancements, biological difficulties, biomedical uses, and translational barriers of liposomal technology will all be covered in this review (Dams et al., 2000).

Anthurium (Anthurium andraeanum Linden) belongs to the complex family Araceae, is a slow growing perennial that requires shady, humid conditions as found in tropical forests. The name anthurium is derived from Greek word “anthos” meaning flower and “oura” tail referring to the spadix. Thus, anthurium is also known as “tail flower” (Tajuddin and Prakash 1996). Anthuriums are gaining popularity due to higher returns per unit area and their beautiful and attractive long lasting flowers. Anthurium ranks ninth in the global flower trade and commands a respectable price both for its cut flower and whole plant. Commercial production has focused on two major species viz. A. andraeanum and A. scherzerianum. A. andraeanum is grown mostly for cut flower production, the main production areas being Hawaii, The Netherlands, and some other tropical and subtropical countries. A. scherzerianum is sold as a flowering potted plant, with main production areas located in Europe. In India, the anthurium cut flower industry is still in its infancy. At present anthuriums are mostly grown in some small gardens and nurseries. The important states cultivating anthuriums are Assam, Kerala, Tamilnadu (Salem), Karnataka (Coorg) and Mizoram where the favourable climate exists (Agasimani et al., 2011).

Tree-borne vegetables spring out from woody perennial plants. There are too many trees in nature across the globe which offer edible fruits, a few of them are exploited for vegetable purpose. Of course, in popular parlance, vegetable gives the connotation of the product of herbaceous crop, but there are vegetables which are the product of woody perennials. In the present agri-horti-scenario, where diversity in product range is the most sought after aspect, attempts are underway to popularize culture of such vegetables which have not yet found commercial momentum at the grower’s field. Tree-borne vegetables are one such group which needs proper popularization to really help to percolate their farming. These vegetables being vested with woody nature, tap root system, bark covering and stress tolerance mechanism are worth exploitation under diverse farming systems prevalent across the country. Further many tree-borne vegetables are rich in nutrients also and as such add to their plus identity.
