Summary

Genes are discrete elements that govern the appearance of specific traits. Morgan Sturtevant and their coworkers demonstrated that genes have specific address. They reside at particular locations on particular chromosomes and these addresses remain constant from one individual of the species to the next. Transcription is the first step leading to gene expression. It is the process of creating a complementary RNA copy of a sequence of DNA. Both RNA and DNA are nucleic acids, which use base pairs of nucleotides as a complementary language that can be converted back and forth from DNA to RNA by the action of the correct enzymes. During transcription, a DNA sequence is read by RNA polymerase, which produces a complementary, antiparallel RNA strand. translation is the second stage of protein biosynthesis (part of the overall process of gene expression). In translation, messenger RNA (mRNA) produced by transcription is decoded by the ribosome to produce a specific amino acid chain, or polypeptide, that will later fold into an active protein.

Root-type vegetables are a diverse group of underground plant structures that are edible and serve as a vital source of nutrition for humans. These vegetables can be further categorized into two main types: true roots, such as carrots, beets, turnips, and radishes, which are modified taproots that store food; and tuberous roots, such as Potatoes, sweet potatoes and yams, which are modified
stems that store food. A root is a compact, often enlarged storage organ with hairy stems that develops from root tissue. So a tuber is a root crop, but a plant can be a root and not a tuber. Carrots and cassava are root vegetable crops. Potatoes, sweet potatoes and yams, on the other hand, are edible tuber crops (Fig. 5.1).
The primary difference in propagation lies in the plant part used: tubers, like potatoes, are propagated from modified stems or roots with “eyes” (nodes) that sprout, while root crops, like carrots, are propagated from seeds or root cuttings, as their roots don’t have these propagation points. Another major difference is that tubers will have long shelf life compared to roots.
• Tubers
• Origin: Tubers are modified stems or roots that store nutrients.
• Propagation: They can be propagated vegetatively by using pieces of the tuber that contain “eyes” (nodes) which sprout and grow into new plants.
• Examples: Potatoes, sweet potatoes, and cassava.

5.1. Introduction

Rice-fallows are a rainfed rice mono-crop production system, where only a single crop (rice) is grown and these lands remain without any crop for the rest of the period of the year (fallow). An estimate shows that rice-fallow areas extended over 22.3 M ha in South Asia, maximum in India ( 88.3%) followed by Bangladesh (8.7%), Nepal (1.4%), Sri Lanka (1.1%), Pakistan (0.5%), and Bhutan (0.02%) (Gumma et al., 2016). The eastern part of India accounts for ~ 84% (9.7 million ha) of the country’s total rice-fallow area (i.e. 11.7 million ha) (Ali et al., 2014; Singh et al., 2017), despite high rainfall during rainy / monsoon season. The reasons are that after the rainy season, irrigation facilities are lacking, very fast depletion of the soil residual moisture due to temperature rise, the poor economic condition of the farmers, and a lack of awareness or knowledge of available technologies. Additionally, delayed harvesting of long-duration rice (150-160 days) results in late sowing of winter crops, which, in turn, exacerbates the temperature and moisture stresses in winter crops (Kumar et al., 2018a; 2018b). Overall, the challenges of growing another crop in rice-fallow areas are the lack of irrigation facilities including declining groundwater levels, the dominance of the long-duration rice varieties cultivation, higher evaporative loss of the residual soil moisture, degradation of soil quality, and poor financial conditions of the farming community with diminishing profit. Recently, climate change with erratic rainfall and delayed monsoon arrival added more challenges for these areas in several places. Deficit soil moisture imposes stress on the crops and negatively affects the winter crops productivity in the rice-fallow system, and several times it results in complete crop failure (Singh et al., 2012; Ghosh et al., 2016).

Introduction 
In a time when the world is in dire need of sustainable energy solutions, investigating biofuels becomes an essential path to supplying the always expanding supply[1]. This book chapter explores the dynamic world of solid and liquid biofuels, providing a thorough analysis of their properties, methods of production, uses, and wider ramifications in relation to renewable energy sources. Setting the scene, the introduction clarifies the role of biofuels in the larger context of renewable energy. Exploring solid and liquid biofuels becomes critical as the globe struggles with issues like climate change, depleting fossil fuel reserves, and the need to switch to cleaner energy sources[2]. These biofuels, which are defined as energy carriers made from biomass, offer a viable substitute and have the capacity to both reduce environmental impact and promote energy security. As the chapter progresses, biofuels are divided into two main categories: liquid and solid. Biofuels that are solid, such as wood, agricultural leftovers, pellets, and briquettes, serve as a starting point for investigating alternative energy sources. This section walks readers through the complexities involved in producing solid biofuel, including harvesting, pre-treatment, and creative pelletization methods. By doing this, it highlights the renewable nature of solid biofuels and their ability to lower greenhouse gas emissions, highlighting their benefits for the environment. Simultaneously, difficulties associated with its application, ranging from administrative worries to land use issues, are examined closely. Turning its attention to liquid biofuels, the chapter tells the story of ethanol, biodiesel, and advanced biofuels. By examining the choice of feedstock, manufacturing procedures, and real-world uses, it highlights the adaptability of liquid biofuels in the energy system. Although they are not without difficulties related to land use, food production, and water use, their ability to function with current infrastructure and their critical role in improving energy security stand out as distinguishing characteristics[3].

Biology is the study of life and living organisms that encompasses a vast range of topics from the microscopic scale of cellular processes to the complex interactions within ecosystems. It explores living organisms’ structure, function, growth, evolution, and distribution, integrating diverse fields such as genetics, ecology, and physiology. Chemistry is often referred to as the central science, delves into the composition, structure, properties, and changes of matter. It explores how substances interact with each other and transform through chemical reactions. This field underpins a multitude of scientific disciplines, linking concepts in physics with applications in biology, medicine, and engineering. The chemistry of living organisms is known as Biochemistry. The concept behind Biochemistry deals with the biology and the conventional chemistry. As we all know living organisms can grow, reproduce, and respond but do you know that all these activities could easily be interpreted by chemistry? The complex organic molecules are present

7.1. INTRODUCTION

The word ‘significance’ in statistics does not describe the strength of association. Statistical significance is simply related to the probability of the result being commonly or rarely encountered (If the probability of chance occurrence is low the result is likely to be determined by the set of circumstances under study and not by chance). If conclusions are to be drawn that a difference exists between two groups of subjects, then we have to ensure that they are equal in all respects except the one under test.

‘P’ values are used to assess the degree of dissimilarity between two (or more) sets of measurements. The ‘P’ value is the probability of obtaining a result as extreme as or more extreme than the one observed. The ‘P’ value is actually a measure of surprise and the smaller the value, the more surprising is the result. When ‘P’ value is between 0.05 and 0.01, the result is usually called statistically significant; when it is less than 0.01, it is usually called highly significant and if, values are lower than 0.005, then it is called very highly significant. Traditionally, the approach had been to indicate the level of significance by rounded off ‘P’ values e.g., P < 0.01. Now it has become a fashion to calculate the exact probabilities and thus arrive at a particular decision.

Introduction to Metabolism Metabolism is the sum of all biochemical reactions (physical and chemical processes) occurring within the body to sustain life. In total, it encompasses all the processes converting the energy from nutrients into usable forms, thereby facilitating the synthesis of biomolecules necessary for sustaining life. This process occurring in all living organisms ensures that a continuous supply of energy and precursors is maintained to perform cellular functions, such as growth, reproduction, maintenance and response to environmental stimuli. Therefore, studying the body’s metabolism provides insights into the physiology, mechanism of disease occurrence and potential therapeutic interventions. Specifically, metabolism is a highly regulated process involving a set of biochemical reactions that can be broadly grouped into: a) Catabolism involves the breakdown of complex molecules into simpler components, releasing energy in the form of adenosine triphosphate (ATP). Catabolic reactions assist in the extraction

8.1 Economic Geology and Ore Mineralogy

8.1.1 Economic geology

Economic Geology deals with the comprehensive study of mineral deposits including their processes of formation and uses. By applying the principles of geology, a mining engineer is able to exploit such deposits profitably for the use of Man.

8.1.2 Ore mineral

An ore is a term applied usually to that part of a metalliferous mineral deposit that can be utilized profitably as a source of one-or-more metals, this term now is widely used for the usable part of many non-metallic (non-metalliferous mineral) deposits, like barite, fluorite, sulphur, etc.

8.1.3 Gangue mineral

An ore is usually a mixture of one or more usable minerals (ore minerals) and one or more unusable minerals (gangue minerals). The usual gangue minerals are quartz and other forms of silica, calcite, dolomite, siderite, barite, feldspars, garnet, chlorite, kaolin, fluorite, apatite, pyrite, pyrrhotite, arsenopyrite, and sometimes the gangue material is the country rock or host rock itself in which the ore minerals occur. Sometimes, the gangue minerals may also be utilized as by-products of the ore deposit. The nature and proportion of the gangue influence the economic value of an ore to a great extent.

INTRODUCTION

Grape (Vitis vinifera L.) is one of the important fruit crop in world grown commercially in temperate, tropical and sub-tropical regions. At present, it is one of the major horticultural industries over an area of 7.5 million hectares. Grape berries are attractive for their unique flavour and are utilized in many different ways, so its cultivation is becoming more popular. Approximately 71% of world grape production is used in wine industry, 27% as fresh fruits and only 2% as dried fruit. China is the largest producer of grapes followed by Italy, USA, France and Spain. In world, India hold 9th position in grapes production with an annual production of 2822.78 thousand MT.Peninsular India comprise of accounts for 90 % area under grapes. India has the distinction of having highest productivity (21.4 MT/ha) of grapes in the world

The science that includes classification, nomenclature and identification of plants is called plant taxonomy. Taxa (Sing. Taxon):A general term for taxonomic classification, irrespective of rank.
18.1 Plant Types (habit and habitat)
1. Annual: A plant that completes its entire life cycle, from seed to reproduction to death, in one single year.
2. Biennial: A plant that completes its entire life cycle in two years.
3. Perennial: A plant that grows and reproduces for many years.
4. Monocarpic: plants that flower and set seeds once during its lifetime. They flower only after attaining maturity. They flower gregariously in a single season e.g. Bamboo and Kurinjis.
5. Polycarpic: Plants that flower and set seeds many times during its lifetime.
6. Aquatic: Organisms growing in water.
7. Shrub: A much branched, small, woody perennial plant with several branches from ground level upwards.
8. Tree: A tall, woody, perennial plant with a single trunk which usually bears branches.

Systematic scientific efforts to improve genetic potential of crops in India were initiated in 1905 at the Imperial/Indian Agricultural Research Institute. In 1929, with the establishment of the Indian Council of Agricultural Research (ICAR), several associated developments took place in the first half of the 20th century leading to establishment of several crop-based institutes (sugarcane, cotton, jute, rice, oilseeds, tobacco, potato) and multidisciplinary institutes such as the Indian Agricultural Research Institute (IARI), Central Arid Zone Research Institute (CAZRI), and Central Plantation Crops Research Institute (CPCRI). Additionally, a Project on Intensification of Regional Research in Cotton, Oilseeds and Millets (PIRRCOM) was implemented during 1950s with establishment of several research stations in different regions.

Rice is the principal crop of the region and cultivated in 3.9 million hectares area with an average productivity of about 1.3 t ha-1, which is very low. Irrigation resources are limited and confined to only 26 per cent and utilized for rice crop only. The region has rice based cropping system, in which lathyrus (grasspea),  is grown as utera (relay crop) in 0.46 million hectares. However, its productivity is not more than 2 to 3 q ha-1. Pulse crops are cultivated in an area of 0.44 m ha in kharif and 0.81 m ha in rabi season. The main pulse crops of the region are lathyrus, black gram, pigeonpea, chickpea, horsegram (kulthi), lentil and field pea. Area-wise, urd in kharif and lathyrus in rabi occupy the top position but as far as productivity is concerned, pigeonpea and chickpea are important. Pigeonpea and chickpea together can contribute a lot in increasing the pulses production in region. The average productivity of pigeonpea is 5.19 q ha-1 . It is also grown on rice bunds, which may give an additional production of 0.06 mt. Mung and urd are grown throughout the year in the region, however, powdery mildew and yellow mosaic virus diseases pose severe threat to these crops.

3.1 Introduction
Since the dawn of humanity, the expansion of invention and technological innovation has made it possible to make a variety of goods to meet its needs. To get a competitive edge in the market, the manufacture of a product has three main goals, viz. efficient product planning, efficient manufacturing, and effective cost control.
These can be achieved through a random thinking, if the designer is fortunate to have the best design of a product of interest, which satisfies the needs of its customers. But it will rarely happen. Design thinking maximizes the possibility of happening of the best design in the journey of design a product in shorter possible time.
Design thinking, an emerging field in this direction, tries to create a product by utilizing the following steps.
i. Empathize
ii. Define
iii. Ideate
iv. Prototype
v. Test
3.2 Definition of Design Thinking
A design methodology called “Design Thinking” offers a problem-based approach to problem solving. By understanding the human needs which changes quickly, re-framing the issue in human-centric ways, generating a lot of ideas during brainstorming sessions, and taking a hands-on approach during prototyping and testing, design thinking is incredibly helpful in handling complicated challenges that are ill-defined or unknown. Anyone can use the Design Thinking approach to tackle complex problems that arise in our society, such as those in our businesses, governments, and other spheres of influence, if they have an understanding of these five steps of the process.

Introduction Organ-On-a-Chip (OOC) is a developing trans-disciplinary technique that shares similarities with tissue engineering and lab-on-a-chip technologies. It has benefited from recent advancements in microtechnology (particularly microfluidics), cell biology, physiology, and tissue engineering and is motivated by the need for reliable, low-cost in vitro drug screening models. It can be characterized as a microfluidic-based perfusion device that facilitates an invitro cell (co-)culture and tries to reproduce certain structure(s), function(s), and important elements of human or animal metabolism of a particular tissue or organ in healthy and pathological physiology. Important features of live organs are such as extracellular microenvironments, spatiotemporal cell-cell interactions, and physiologically important tissue microarchitecture.

Supply Chain and Inventory Control
A supply chain refers to the interconnected network of individuals, organizations, resources, activities, and technologies involved in the creation and delivery of a product or service from its origin to the end consumer. It encompasses all stages of production, including sourcing raw materials, manufacturing, transportation, warehousing, distribution, and the final delivery to customers.
Key components of a supply chain include:
1. Suppliers: Entities that provide raw materials or components necessary for production.
2. Manufacturers: Organizations that convert raw materials into finished products through various processes.
3. Distributors: Companies that handle the logistics of transporting goods from manufacturers to retailers or directly to consumers.
4. Retailers: Businesses that sell products to end consumers, either through physical stores or online platforms.
5. Customers: The final recipients of the product or service.
Preparation of Drug Lists
The preparation of drug lists is an essential component of medication management in healthcare settings. These lists help ensure that healthcare providers have access to the necessary medications while promoting safe and effective use. Below is a detailed overview of various categories of drug lists, including high-risk drugs, emergency drugs, Schedule H1 drugs, NDPS (Narcotic Drugs and Psychotropic Substances) drugs, and reserved antibiotics.
