The increasing capabilities of Large Language Models have created strong demand for real-time AI services, but their computational complexity makes low-latency deployment difficult on conventional systems. Transformer models require substantial memory, high computational throughput and efficient data movement, creating challenges for mobile devices, embedded systems, edge platforms and latency-sensitive applications. This chapter introduces hardware–software co-design as an integrated strategy for addressing these challenges. Rather than optimizing hardware and software independently, co-design aligns model algorithms with the characteristics of processors, memory hierarchies, accelerators and communication systems. The chapter examines hardware platforms including GPUs, TPUs, FPGAs and ASICs, together with software techniques such as quantization, pruning, knowledge distillation, operator fusion and memory scheduling. Hybrid architectures are discussed for reducing latency, improving throughput, lowering energy consumption and increasing scalability. Applications in healthcare, finance, autonomous driving, robotics, industrial IoT and real-time translation illustrate the importance of efficient inference. The chapter demonstrates that coordinated optimization across the full computing stack can bridge the gap between LLM capability and practical real-time deployment while maintaining acceptable accuracy and reliability.

Abstract

Indigenous Peoples of northwestern North America have utilized several hundred local plant species, as well as some algae, lichens and fungi, in their traditional diets. Many of these are also used in traditional healing, and some have potentially harmful or poisonous properties that must be taken into account in harvesting and preparation. Other species, known primarily for their medicinal use, also have noted toxicity if used improperly or without constraints. In this study, a total of 375 traditional food and medicine plants, fungi, lichen and algal species, as well as those species reported to be toxic by indigenous knowledge holders, were surveyed across 12 First Nations groups, each with distinct languages, for overlaps across the categories of food, medicine and toxic species. A complex of species use and avoidance emerged, modulated by processing, dosage, and other factors, with significant numbers of food species with reported healing properties, food species also used as medicine, and both food and medicinal species known to be harmful or toxic under some circumstances. Even most of those species considered extremely poisonous have been taken internally as medicines in some way by some groups.

Vegetable research in India is of very recent origin. Research on vegetable crops was started by ICAR with the sanctioning of a nucleus ‘Plant Introduction Scheme’ at IARI, New Delhi in 1947-48. Simultaneously, the ICAR also started such ad-hoc schemes in different states like Punjab, Uttar Pradesh, West Bengal, Maharashtra, Himachal Pradesh, Jammu & Kashmir and Tamil Nadu.

Prior to World War II, entire seeds of temperate vegetables were imported from European countries. When, during World War II, supply of vegetable seeds from Europe suffered a serious setback, the government of India felt the need for production of these seeds within the country. As a result of this, the government of India established a Vegetable Breeding Station at Katrain in Kullu Valley, Himachal Pradesh in 1949. This station was transferred to Indian Agriculture Research Institute in 1955 to undertake research on improvement of temperate vegetable crops, standardization of their seed production technology and to produce seeds of identified improved varieties of temperate vegetables. This research station is carrying out intensive research on all aspects of temperate vegetables including improvement, production technology and their seed production.

Further, a division of Horticulture was created at the Indian Agriculture Research Institute, New Delhi in 1956-57. However, vegetable research was organized on sound footing with the establishment of the Indian Institute of Horticulture Research (IIHR) at Bangalore with a full fledged Division of Vegetable Crops in 1968. The vegetable research in India received a further boost when a separate division of Vegetables Crops and Floriculture was started at IARI, New Delhi in 1970. The floriculture work was separated from the division of Vegetable Crop and Floriculture, IARI, New Delhi in 1982 and the division was then named as Division of Vegetable Crops, which was assigned the research work exclusively on different vegetable crops. In the Sixth Five-year Plan, IIHR, Bangalore started two Central Horticulture Experiment Stations, one each at Ranchi, (Bihar) and Godhra (Gujarat) to intensify research on horticultural crops in important tribal areas of the country where research on vegetable crops was also started to meet the specific requirements of these regions. Establishment of Agricultural Universities and All India Coordinated Vegetables Improvement Project gave further fillip to vegetable research in India.

1. Introduction Plants naturally contain compounds called phytochemicals. Due to their numerous therapeutic applications, these phytochemicals are becoming more and more well-known these days. Phytochemicals are essential in the fight against a variety of illnesses, including cancer, arthritis, and asthma. These phytochemicals have no side effects like pharmaceutical compounds do. Because the phytochemicals treat illnesses without harming people, they can also be referred to as “man-friendly medicines.” The primary topics of this study are phytochemical collection, extraction, and qualitative and quantitative analysis. In order to protect themselves against herbivores, many plants secrete chemical substances. Examples of therapeutic plants that include the main groups of pharmacologically active phytochemicals are provided below. Weeds that contain phytochemicals, like chickweed, dandelion, and nettle, are frequently found surrounding human settlements. Many phytochemicals, including curcumin, epigallocatechin gallate, genistein, and resveratrol are pan-assay interference compounds and are not useful in drug discovery.

Abstract

Scholars have long been interested in the effects of markets on the diet of native populations because of diet’s direct impacts on health. Exposure and assimilation into a market economy result in shifts in modes of subsistence and decision-making about food consumption. But the clear direction of influence is often elusive. Increased market integration predicts expanded access to goods and services that may improve household and individual diet. At the same time, greater involvement in market trade can shift economic priorities away from secure subsistence production toward the lure of material gain and novel items. Here, we analyze the effects of integration into the market economy on household diet using data from a panel study of two villages of Tsimane’, an indigenous group of lowland Bolivia. Because the Tsimane’ have been undergoing varying degrees of integration into the market economy, they provide an ideal population among which to examine the relation between markets and dietary change.

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. At its core, a theory systematically explains a phenomenon or set of phenomena. It involves a coherent set of interrelated concepts, assumptions, and propositions that define causal relationships and offer predictive insights (Kerlinger, 2000). According to Prasad et al. (2017), theory represents a systematic grouping of interdependent concepts that offer a framework to organize existing knowledge, explain observable events, and predict yet-unobserved outcomes. Hollander (1967) adds that theories contain one or more functional statements or propositions that articulate relationships between variables to account for empirical realities. Central to any theory are concepts, the building blocks that articulate the causal linkages and assumptions within a conceptual system. When structured together, these elements form a deductive framework for reasoning and explanation. In sum, theory allows us to understand what is happening in digital governance and why, how, and with what implications. Digital governance, distinct from narrower terms like e-government or e-governance, is a multi-layered process involving the reconfiguration of power, the redesign of institutions, the engagement of diverse stakeholders, and the transformation of public value creation in a digitally mediated environment. It encompasses dimensions of public administration, information systems,

Abstract

Starch is an important plant-based product and an abundant biomaterial, used worldwide for different purposes in many industrial sectors including food, health, chemical and engineering sector. Starch versatility in industrial applications is largely defined by its physicochemical properties and functionality. Starch in its native form has limited functionality and application but advancements in technological processing have led to the wide-range modification of starch for different purposes. It can be easily degraded by microorganisms hence is a natural source of bioenergy in the form of bioethanol and biohydrogen as well as in the development of biodegradable packaging materials. Various technological interventions can significantly improve the characteristics of native starch and be tailor-made to the specific needs of the packaging and food industry. Native starch can be treated by various methods to modify its characteristics. Modification improves starch paste clarity, viscosity, syneresis and freeze-thaw stability leading to a wide range of food applications. Esterification lowers gelatinization temperature and retrogradation lowers the tendency to form gel and higher paste clarity which shows applications in refrigerated and frozen foods, as emulsion stabilizers and for encapsulation. Cross-linking increases the stability of granules towards swelling, high temperature, high shear, and acidic conditions. Starch-based nano-composite polymers have their application in coating and packaging of food as well as non food commodities. Techniques involving extrusion, casting, spinning, and nanotechnology can be used in the production of films, foams, and nanocomposite materials. Due to the unique characteristics of resistant starch, it is being used as a valuable supplement in the formulation of drugs, pharmaceuticals, various functional foods and in the microencapsulation of probiotics and bioactive compounds.

Price mechanism is an economic term that refers to the buyers and sellers who negotiate prices of goods or services depending on demand and supply. A price mechanism or market-based mechanism refers to a wide variety of ways to match up buyers and sellers through price rationing.An example of a price mechanism uses announced bid and ask prices. Generally speaking, when two parties wish to engage in a trade, the purchaser will announce a price he is willing to pay (the bid price) and seller will announce a price he is willing to accept (the ask price).

ABSTRACT

Pesticide degradation is the breaking down of toxic pesticides into a non-toxic compounds and, in some cases, down to the original elements from which they were derived. The most common type of degradation is carried out in the soil by microorganisms, especially the fungi and bacteria. Microbial degradation depends not only on the presence of microbes with the appropriate degradative enzymes, but also on a wide range of environmental parameters. Pesticides which are rapidly degraded are called non-persistent while those which resist degradation are termed as recalcitrant (persistent). Microorganisms are able to degrade a large variety of compounds, including pesticides under laboratory conditions. However, methods have yet to be developed to decontaminate the environment from pesticide residues. Continuous efforts are required in this direction, and at present several PGPR capable of degrading pesticides have been isolated from the natural environment. Catabolic genes responsible for the degradation of several xenobiotics, including pesticides, have been identified, isolated, and cloned into various other organisms such as Streptomyces, algae, fungi, etc. In addition, recombinant DNA studies have made it possible to develop DNA probes that are being used to identify microbes from diverse environmental communities with a unique ability to degrade pesticides. Bioremediation treatment still requires more intense research through specific microbial degradation of broad range of organic pollutants. This review describes recent advances in biodegradation of pesticides by addressing the microbes involved in pesticide degradation.

The physio-chemical properties of ice cream strongly influence its processing behaviour, texture, stability, and consumer acceptance. This chapter examines ice cream as a complex multiphase system and discusses important properties including overrun, density, viscosity, freezing behaviour, hardness, scoopability, meltdown, and fat destabilization. It explains how formulation and processing conditions influence these properties and how they relate to sensory quality. The chapter also considers quality-control tests used in industrial ice cream plants and identifies defects associated with physio-chemical imbalance. Understanding these relationships enables manufacturers to establish suitable product targets, diagnose quality problems, optimize formulations, and maintain consistency across different ice cream products.

Sugar originated from the Arabic word “sharkara” and is derived from the sanskrit world “sharkara”. Sugar is an important part of the daily diet and  forming a class of edible substances which includes  sucrose, lactose, and fructose. It provides the human body with requisite carbohydrates and is basically extracted from sugar cane and sugar beet.  Found in fruits, honey, sorghum, sugar maple and in several other sources, it is the main ingredient of candy which is loved by children the world over. Yet, it has been  blamed for causing tooth decay and excess consumption of sugar has been associated with a host of ailments like diabetes, obesity, weight gain, depression, joint pain, fatigue and insulin resistance and even cancer.

The functional diversity of chemicals within plants is best demonstrated by terpenoids. More than 30,000 terpenoids have been identified, each one composed of 5-carbon (prenyl diphosphate) building blocks added together to make 10-carbon, 15-carbon, and even 2000–500,000-carbon chains, as is the case for rubber. Terpenes are functionally diverse, and many are integral to primary metabolism, e.g., hormones such as gibberellins and abscisic acid, electron carriers such as plastoquinone and ubiquinone, terpene-derived compounds that form structural parts of membranes such as phytosterols, and photosynthetic pigments such as carotenoids.

Plant terpenes are also available as essential oil or ethereal oil. Essential oil is defined as the volatile oil obtained by the steam distillation of plants. There is a distinction between fixed or fatty oils and volatile oils. Their volatility (boiling point) and plant origin are characteristic properties of these oils.

Preparation and processing of the ice cream mix determine the functionality, safety, and consistency of the final product. This chapter describes the complete mix-processing sequence, beginning with ingredient measurement and blending and continuing through pasteurization, homogenization, cooling, and aging. It explains the purpose of each operation and its effect on proteins, fat globules, stabilizers, viscosity, microbial safety, and structure. Aging is particularly important because it supports fat crystallization and hydration of proteins and stabilizers, improving whipping and texture. The chapter also discusses common processing defects, corrective actions, and practical standard operating procedures, providing an industry-oriented framework for producing consistent and high-quality ice cream mixes.

Introduction

Bacterial diseases of solanaceous crops like tomato, brinjal, chilli, capsicum and potato are the most serious and destructive diseases affecting both under field and greenhouse conditions. Under moist field conditions they can cause epidemics to affect total crop loss, quality of the produce and reduce market value. These diseases can be distinguished from each other on the basis of their symptoms appearanceofthe various parts of the plant as well as by using advanced techniques of diagnosis. Diagnosis of the disease is important step to detect pathogen at early stage of disease and subsequently manage it effectively in efficient manner. Therefore, the early detection of the bacterium from asymptomatic plants, soil, and water and plant residues could facilitate elimination and certainly reduce the risk of crop loss. Powerful tools for the identification and detection of the bacterium in diverse substrates (plant, seed, water and soil) are available for diagnosis of the bacterial diseases. DNA amplification of pathogen offers many advantages over classical techniques; neither purification nor cultivation of the pathogen is required and the specificity, sensitivity and response time of tests are improved. Nevertheless, the PCR method has not yet become a routine diagnostic tool for many laboratories, mainly because of the inhibition of the amplification reaction by compounds contained in crude bacterial extracts, which give false negative results or low detection sensitivity.

1.1 Introduction

Horticulture is defined as “The science and art of growing vegetables, fruits, flowers, ornamental plants and landscaping of gardens and surroundings in small and commer cial gardens”. The word ‘horticulture’ has been derived from Latin language and con sists of two parts, viz., ‘hortus’ means garden and ‘cultura’ means cultivation. Thus, the word ‘horticulture’ means garden cultivation. Horticulture basically deals with Pomology, Olericulture, and Floriculture and Landscaping. Horticulture is gaining im portance as it gives more returns per unit area and also gives nutritious food to human beings thereby improves quality of life and enhances the aesthetic beauty of nature. Vegetable growing is one of the major branches of horticulture with respect to value of the products.

Abstract

The Saanich (Coast Salish) are an Indigenous people of southern Vancouver Island on the southwest coast of Canada who for many centuries have relied heavily on anadromous Pacific salmon (Oncorhynchus spp.) as a major food source. Over time, Saanich fishers have become experts on many aspects of these salmon, including knowledge of the different species, their life cycles, feeding ecology, migration routes, and population dynamics. Much of this knowledge is centered at Saanich Inlet and Goldstream River, a major salmon spawning stream flowing into this inlet. Some Saanich and other Coast Salish people still fish for salmon at Goldstream using traditional gaff hooks and spears, but they have also adopted more modern gear in recent times. Pacific coho (O. kisutch) and chum (O. keta) salmon stocks in particular have fluctuated over the decades, evidently due to impacts of commercial fishing, pollution from oil leakage and domestic sewage in Saanich Inlet.

Application of manures and adoption of proper cultivation practices have profound influence in yield and quality of tubers. There crops also need macro nutrients (N,P,K which are primary nutrients and Ca, Mg and S which are secondary nutrients) and micro nutrients (Fe, Mn, Zn, Cu, Mo, B) for their maximum yield potenial.

the package of practices vary with crop and again with soil, climate, edaphic and topographic factors, especially with reference to tropical tuber and root crops. The yield can be maximized through good agronomical practice and by adoption of proven recommended production technologies. Soils, climate, topographic and edaphic factors suitable for each crop alongwith salient cultivation practices and production technologies are enunciated for important tuber and root crops in various parts of India.

Constraints in adopting and carrying out research in agroforestry along with future strategies to extend agroforestry in Uttaranchal are also given in the paper.

INTRODUCTION

Uttaranchal, formed on November 9, 2000, is the 27^th state in India. The state is spread over 53,483 km² of land, which extends between 77° 34’ and 81° 02’ E longitude and between 28° 43’ to 31° 27’ N latitude. It covers 1.67 per cent of the country’s total area and is home to 84.7 lakhs of people as per the provisional census report 2001. The entire state forms part of the Central Himalayas. The state is strategically located and forms part of the Northern boundary of the country sharing its borders with Nepal and China. The entire region, except the southern most foothills belt, is mountainous with a series of ridges and valleys. Starting with an altitude of about 240 m in the tarai on the southern fringes, the terrains rise to 7817 m in the north with in a short width span of about 160 km. It touches Tibet in the north, Himachal in the west and northwest, gangetic plains of Uttar Pradesh in the South and Nepal in the east. Uttaranchal has two administrative divisons, the western half known as Garhwal and the the eastern region known by the name of Kumaon.

1. SEED PATHOLOGY

The area of science that studies the relationship between pathogens and seeds is seed pathology.

2. TYPES OF PATHOGEN

Diseases of plants are caused primarily by three types of pathogens: bacteria, fungi, and viruses. Despite that fungi comprise the largest group of pathogens, the bulk of seed-specific diseases are caused by bacteria or viruses. This is due to the fact that bacteria and viruses are more adopt at entering and then travelling through the veins of the plant, a phenomenon known as ‘systemic infection,’ and from the vascular system may make their way into the developing embryos of seeds.

Fungi, in contrast, tend to be restricted to the outer layers of the plant, where they initiate infection by means of air-borne spores and then proceed to spread by attacking nearby cells of the outer layers. Fungi are much less likely to enter the vascular system of the plant, and thus infect seed mostly when they either ‘crawl’ all the way to seed on the outside of the plant, or else send out spores that land on the seed. In either case, the fungal spores are on the outside of the seed, in the layers of the seed coat, spores on the seed coat are more prone to either dry up and die, or else to get sloughed off with the seed coat during seed germination, thereby failing to cause disease on the next generation of plants.
