1.1 Introduction
The concept of invention is the fundamental requirement for design thinking. Since the birth of mankind, people started inventing many concepts, which are mainly observations of facts and innovation of ideas for producing products that are useful to the society. The design thinking requires unconventional thinking to design processes for maximal operational efficiency of manufacturing the products, which give maximum satisfaction to customers with more value for money. Hence, the team that is involved in the design thinking projects may gain the required skills by knowing several inventions of the past. Hence, a review of inventions is presented in this chapter.
1.2 Tracing Inventions
The content at https://www.explainthatstuff.com/timeline.html gives a complete account of inventions starting from 4–5 billion years ago up to 2022. The article on solar cell energy gives an account of the sun started producing energy. About 1.2 million years ago, humans invented fire, which has been further innovated for biofuels, candles, IC engines, aviation engines, etc. In the 7th century B.C., ants were killed by burning in the heat produced by concentrated sun rays using magnifying lens. Greeks and Romans utilised burning mirrors to light candles during religious ceremonies in the third century B.C. About 3.5 million years ago, stone, wood, antlers, and bones were used by humans to make first kind of tools. These were further improved to make tools for machines. About 4000 BCE back, iron was used to make decorative ornaments. About 3500 BCE, people invented the concept of wheel, which brought quantum revolution in transportation.

Microorganisms (or microbes) are organisms too small to be seen with the naked eye. The science of microbiology is the study of microorganisms, their properties, classification, growth requirements, method of reproduction and distribution in nature. These organisms range in size from tiny viruses to larger bacteria, protozoa, algae, fungi and some of the microscopic worms (helminthes). They are present everywhere in our environment, in our homes, on our bodies, on the things we touch and on the food we eat. They are important for human survival on Earth, playing an essential role in many processes that maintain life. In nature, microorganisms carry out a number of important functions.

1.They are responsible for the decomposition of organic matter.

2.Recycling of nutrients that help to maintain the balance of chemicals in the soil.

3.Special nitrogen-fixing bacteria live symbiotically with certain plants, absorbing nitrogen from the air and converting it into compounds which can be used by the plant for growth.

4.Some algae are capable of photosynthesis, using energy from the sun to convert carbon dioxide in air into carbohydrate.

5.Marine microorganisms form the basis of the food chain in lakes, rivers and oceans.

6.Certain microorganisms are used in the manufacture of food.

7.Pharmaceuticals and drugs.

8.Industrial processes.

9.A valuable tool for scientific research.

10.Use in laboratory experiments to understanding metabolic pathways and in the discovery of the genetic code.

Obviously human have had to deal with microbes even before the recorded history. The first record of human using microorganisms comes from ancient tablets from mid east.

Babylonians were using yeast to make beer over 8000 years ago and acetic acid bacteria to make vinegar over 6000 years ago. About 5000 years ago, Persia (Now Iran) region recorded the wine making.

The Romans had God for specific microorganisms. The roman God of mold and mildew were “Robigus” and “Robigo” which mean crop rust. (Rust is one of the plant disease caused by fungus). God Robigus was very much feared because of crop lost. About 2000 years ago, Romans proposed that diseases were caused by tiny animals. But, fundamentalist religions had a strong hold over the progress. The real microbiology history starts from 1600s, when people began to make crude lenses and microscopes.

WORLD HISTORY

Work on ornamental crops was first initiated in Krelage Nursery founded by Ernst Heinrich Krelage for bulbs, lilium and dahlias in 1811. During 1895, Taiwan Agricultural Research Institute was established for ornamental crops. The first yellow corn Golden Bnatam was listed in Burpee’s Catalogue in 1902. In 1909 Primadonna F1 hybrid variety of begonia was released by the Benary Seed Company in Germany and in the same year Atlee established seed farms at Floradale in California, Erfurt in Germany Anglia in UK and Kashmir valley in India for annual garden flowers. Luther Burbank did excellent breeding works on ornamental trees, flowers and fruits in 1926.

Luther Burbank did excellent breeding works on ornamental trees, flowers and fruits in 1926.

David developed the first successful hybrid in Nasturtium (1934) and Red and Gold hybrids of marigold (1937). In 1940, Burpee was successful in chromosome doubling and transformation of wild flowers and developed “Bright Scarlet” and “Super Tetra Series” in antirrhinum and “Jumbo Scarlet” in zinnia. He produced new strains of marigold, zinnia, nasturtium and snapdragon. William Houston in 1940 initiated the Ageratum breeding. Morden Research station was set up in Western Canada in 1945 for ornamental crop breeding. In 1968, Dr. Gustav A.L., Mehlquist was recognized as an international authority on breeding of ornamental plants. George J. Ball breeder of peas, asters and calendulas was a pioneer for the supply of dwarf impatiens and orange impatiens ‘Super Elfin’ in 1968. Israeli breeders during 1990 gave more attention towards the development of carnation, lily and anemone varieties. Longwood Gardens in 2008 got success in breeding of stock. The first record of chrysanthemum hybridization, germination and selection of superior seedlings occurred in 1827 by M. Bernet.

It will be unjust not to describe history of Parasitology (31) and a little bit about Parasitology (chapter 8) so that our students may know the earlier works done in this field and how research has advanced by diligent observations of the eminent scientists when they were not having such sophisticated facilities.

As helminth is visible with naked eyes, it was this parasite which man encountered first in its journey of life sciences or natural sciences,as was known in ancient times. Some of these were known even before the era of biblical Palestine and ancient Egyptian civilization. Hippocrates (460-357BC), ‘Father of Medicine’ knew about pinworms (Oxyuris equi) of horses. In his “History of Animalium”, Aristotle (384-322 BC)(32) has mentioned three kinds of helminthes-flatworms, cylindrical worms (Ascaris lumbricoides) and thinworms (Enterobius vermicularis). The treatises of India had the information on large roundworms of intestine (Ascaris), pinworms, leeches, bed bugs and mosquitoes.

The history of plant breeding is divided into 4 periods- knowledge of plant breeding before 1900, application of genetic principles (1900-1940), plant breeding research after 1940 and the recent developments in plant breeding. Emphasis is given on the land marks in genetic improvement of vegetable crops.

The major land marks  in genetics and breeding of crop plants are listed below.

In light of the high population of nematodes, N.A. Cobb (1915) who is considered to be the father of American Nematology, provided a dramatic description of the abundance of nematodes. He stated, “if all the matter in the universe except the nematodes were swept away, our world still would be dimly recognisable. We would find its mountain tops, valleys, rivers, lakes and oceans represented by a film of nematodes.” The Papyrus Ebers suggested a knowledge of the human intestinal parasite, Ascaris lumbricoides and the tissue parasite, Dracunculus medinensis. In early Egyptian writings also these two human parasites have been described. In 1956, Borellus recorded his observations “Vinegar eels” the microbivorous or free living nematode occurring in most vinegar at that time. The statement “sowed cockle, reaped no corn” in Shakespeare’s “Love’s Labour’s Lost”, act 4, scene 3, as suggested by Thorne (1961) possibly the first record of plant parasitic nematodes in 1549. The nematode that Thorne suspected to be in that reference actually was described by Needham in 1743. Subsequently, discovery of microscope and developments in various disciplines of science led to the discovery of plant parasitic nematodes and the disease caused by them. Some of the important milestones on the history of plant nematology are listed below in chronological order.

Plant diseases are mentioned in some of the oldest books available (Homer, C – 1000 B.C. mentioned about the therapeutic properties of sulphur and in Old testament – 750 B.C.) and were feared as much as human diseases and war.

Comprehensive History of Plant Pathology
Mycology
1. Ancient Contributions (1500–500 BC): Ancient Indian texts like the Rigveda and Atharva Veda mention plant diseases, indicating early awareness of pathogens affecting crops. Although these texts are religious and medicinal in nature, they reflect early observations of how environmental factors like fungi and pests could impact plant health, laying the foundation for later agricultural practices.
2. Theophrastus (286 BC): The Greek philosopher and botanist, Theophrastus, often called the “Father of Botany,” made some of the earliest written references to plant diseases in his work Enquiry into
Plants. His observations of plant diseases such as rusts, mildews, and galls were foundational, even though he did not recognize them as caused by fungi. His work represented an important step towards formalizing plant pathology.
3. Kautilya (321–186 BC): The ancient Indian scholar Kautilya, also known as Chanakya, in his treatise Arthashastra, discussed plant diseases and methods of pest control, reflecting the integration of plant health into agricultural management and governance. His work highlighted the recognition of crop loss as an economic concern during ancient times.

3.1. History and Development of Plant Classification
The botanical term “Angiosperm”, from the Ancient Greek ‘angeíon’ (receptacle, vessel) and seed, was coined in the form Angiospermae by Paul Hermann in 1690, as the name of that one of his primary divisions of the plant
kingdom.
This included flowering plants possessing seeds enclosed in capsules, distinguished from his Gymnospermae, or flowering plants with achenial or schizocarpic fruits, the whole fruit or each of its pieces being here regarded as a seed and naked.
Its use with any approach to its modern scope only became possible after 1827, when Robert Brown established the existence of truly naked ovules in the Cycadeae and Coniferae, and applied to them the name gymnosperms. From that time onwards, so long as these Gymnosperms were, as was usual, reckoned as dicotyledonous flowering plants, the term Angiosperm was used antithetically by botanical writers, with varying scope, as a group-name for other dicotyledonous plants.
In 1851, Hofmeister discovered the changes occurring in the embryo-sac of flowering plants, and determined the correct relationships of these to the Cryptogamia

The word chicken originated from old English word ‘icen’, Germanic word ‘kivkenam’ and cock (‘keuk’). According to Charles Darwin, the original chicken (Gallus domesticus) from which all modern domestic breeds of chicken have descended is referred to as Red Jungle Fowl (Gallus gallus). Archaeological discoveries in the Indus Valley suggest that chickens were probably domesticated from the Red Jungle fowl (Gallus gallus) as early as 5400 B.C. (West and Zhou, 1988). But there are some others who believe that modern chickens have been contributed by four wild species found in South East Asia. These were Gallus gallus (Red jungle fowl) found in eastern part of India, Burma, Java and Sumatra, Gallus sonneratii (Grey jungle fowl) prevalent in western and southern parts of India, Gallus lafayetti (Ceylone
jungle fowl) the native of Sri Lanka and Gallus varius (Javan jungle fowl) found in lower adjacent islands of Java.
2.1. Origin of Modern Poultry
• 8000 BC
Archaeological evidence suggests that chicken existed in China
• 5400 BC
China - Cishan culture; but contribution of these birds to modern birds are doubtful.
• 3000 BC
In India account of cock fighting indicate that chicken have been part of the culture for a long time.

Abstract

The knowledge of programming language(s) is necessary to solve biocomputational problems and also understand the data pattern. Computer programming is used to develop software to extract information from data which is very crucial while practicing bioinformatics. Programming language is a man-made, computer-understandable, artificial language, that is designed to instruct a machine, particularly a computer to get the desired output. This chapter briefly narrates the concept of algorithms, programming languages, and the historical perspective of the same.

Rabbits belong to the mammalian order Lagomorpha, which includes rabbits, hares, and Pikas. Fossil records indicate that Lagomorpha originated in Asia over 40 million years ago during the Eocene period. The continental drift during this period likely contributed to the diverse distribution of rabbit and hare species worldwide, excluding Australia. There are over 60 recognized breeds of domestic rabbits in Europe and America, all descended from the European rabbit (Oryctolagus cuniculus), the only widely domesticated rabbit species. This species is distinct from native rabbits like North American jackrabbits and cottontail rabbits, as well as all hare species.

Nowhere in the plant kingdom do ecology, evolution, and human affairs come together as intricately as phenomena involving secondary metabolites. The importance of these compounds is apparent in some of the earliest annals of human history. For example, Papaver somniferum, the original source of morphine and codeine, was known to the Sumerians in 4000 B.C. as hul gil (joy-plant). These two alkaloids, so important in human affairs for many years, probably evolved within the genus Papaver originally as protective compounds against herbivores. As a testament to the importance of secondary metabolites,

P. somniferum was one the first plants to be cultivated for a reason other than its caloric or nutritive value. Sadly, its importance has only increased over the time. Organic chemists of the nineteenth century were among the first to recognize and study the diversity of plant secondary metabolites and to analyze them both in terms of structure and function. The German organic chemists developed techniques to acetylate morphine and produce what they claimed at the time to be a non addictive version of the drug. However, acetylation product of morphine trade name Heroin, was vastly more addictive. The economies of several developing nations in Asia still depend on the acetylation of this plant secondary metabolite, and tens of thousands of lives each year are destroyed by its commercial importance. In another striking example of profitable secondary metabolites, acetylation techniques to salicylic acid, derived originally from the bark of willows, Salix, to create aspirin. The modern appreciation of these secondary metabolites from ecological and evolutionary perspectives had its spread outside of the plant-insect ecology community. The overwhelming array of chemicals found in plants was more than simply by-products of primary metabolism that served as waste products for these organisms that lacked excretory systems.

Ecologists and evolutionary biologists soon took up the cudgels, and the past 60 years have seen the development, testing, refinement, and, in some cases, rejection of models that describe the ecology and evolution of these “secondary” substances. With the functional roles of these compounds broadly acknowledged, several challenges presented themselves to scientists interested in their ecological and evolutionary dynamics. Most obviously, the details of the processes underlying the interactions between each of these compounds and their target pest or pathogen became one of the most vibrant topics in ecological and physiological research.

History and development of seed Industry in India can be discussed under two heads

1. Pre-independence development.
2. Post-independence development.

The paper deals with the historical perspective of the tsunamis, much widely discussed Kumari Kandam and Lemuria continent and the palaeo-time series changes on the past continents and oceans, disastrous tsunamis since 16^th century and archeological evidences indicating shore line changes along Tamil Nadu coast.

Keywords: Ancient tsunamis in history, Kumari Kandam and Lemuria, Past shore line changes.

INTRODUCTION

A tsunami is a natural phenomenon consisting of a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale. Earthquakes, landslides, volcanic eruptions and large meteorite impacts all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable phenomenon to large scale devastation.

The term “tsunami” is derived from the Japanese language meaning harbour (“tsu”) and wave (“nami”). The term was coined by fishermen who returned to port to find the area surrounding the harbour devastated, although they had not been aware of any wave on the high seas. A tsunami is not a sub-surface event in the deep ocean; it simply has a much smaller amplitude (wave heights) offshore, and a very long wavelength (often hundreds of kilometers long), which is why they generally pass unnoticed at sea, forming only a passing “hump” in the ocean.

Tsunamis were historically referred to as tidal waves because when they approach land they take on the characteristics of a violent onrushing tide rather than the sort of cresting waves that are formed by wind action upon the ocean (with which people are more familiar). However, since they are not actually related to tides the term is considered misleading and its usage is discouraged by oceanographers.

History and History Taking History in medical/ veterinary terminology is a record of information about the health, illness (past and present), diet, feeding, management,preventive health schedules (vaccination,deworming, dipping, sprays) and hygiene etc. History taking and physical examination is the important step in making a correct diagnosis as it provides valuable information to determine the cause of clinical manifestations. The main purpose of taking history is to get detailed information about the animal, its activities, behavior, diet, health care practices, nutritional status, housing, development of abnormal signs and treatment given, if any. The animal may be cared by owner himself or by an attendant. In the event of animal care given by an attendant, information obtained from the attendant may not be complete and fully reliable as sometimes attendant may not provide correct events and complete picture to hide his mistakes. For obtaining right information a good rapport is to be made with the owner or the attendant. A complete history not only suggest diagnostic possibilities but can also suggest diagnostic probabilities. For example a calf or heifer is unlikely to have Johne’s disease or an adult cow is more likely to suffer from parturient paresis than a first calf heifer. History can also provide a lead for further examination or which system is to be paid special attention.

Making a correct and an early diagnosis is very much important for undertaking rational and effective treatment for fast recovery, avoiding unnecessary medication, reducing the load of so many drugs on body metabolism, reducing environmental pollution and the cost of treatment. There are four important pillars for making a correct diagnosis viz. the history, the systematic clinical examination, the correct clinical diagnostic techniques and the laboratory support. History Taking Clinician’s first step in making a diagnosis is through asking the owner’s complaint. Accurate and complete history may be obtained from focusing on the details of the patient (name, number, species, breed, age, sex and weight), vaccination status, deworming schedule, nutritional history, past and present medical history and environmental history.

History and thorough physical examination is crucial procedures in making diagnosis in horses. Mental attitude of a horse may help in understanding whether it has a localized problem or is systemically ill. Horse is better approached by its left side, keeping himself/herself next to the shoulder. Examination of the horse should be started in a non-threatening, easy, and quiet way. Generally physical examination starts at the head to prevent possible injury to unfamiliar examiner. Abnormalities in demeanor and mentation can be assessed by watching the horse’s initial response to the environment. The locomotor and neurologic systems are examined by observing the horse’s movements and gait at walk and trot, both on straight line and in turns, and backing. Horse weight should be taken. General inspection of the horse should be conducted by standing back keeping a safe distance and looking at the horse for it condition, abdominal shape, muscle symmetry,

Small ruminants are grazing mammals and this group consists of sheep (Ovis aries) and goats (Capra hircus).Advantage of these animals is their low cost, small size and marginal land use, which convert into high quality animal products. Sheep is a grazing animal and goat is a browsing animal. They are generally kept in flock. Therefore flock management is more important than the individual animal. Though, procedure of history taking and physical examination is almost similar to other animals, some peculiarities warrant a separate discussion. Sheep The general methods of history taking and physical examination of sheep are similar to cattle and goat starting from owner’s complaint (history), signalment of the patient, history of the ailing

Aromatic plants synthesise and preserve a variety of biochemical products, many of which are extractable and useful as chemical feed stocks or as raw materials for various scientific investigations. Many secondary metabolites of plants are commercially important and find use in a number of perfumery, flavouring and pharmaceutical compounds. The characteristic property of the plant is due to a variety of complex chemical compounds and hence aromatic plants are generally referred to as ‘natural bio-chemical factories’ or ‘chemical goldmines’.  Not all these natural chemicals can be synthesised in laboratory. Aromatic plants possess odorous volatile substances, which occur as essential oil, green exudate, balsam and oleoresin in one or more parts, namely, root, wood, stem, foliage, flower and fruit.  The term essential oil is concomitant to fragrance or perfumes because these fragrances are oily in nature and they represent the essence or active constituents of plants. They are called volatile or ethereal oils as they evaporate when exposed to air at ordinary temperatures.

Good Angora breed yield wool of 2-2 ½ “ an average. On record, 8” of wool is also obtained.

Among angiosperms, there are about 18 families which have more than 30 genera which produce tubers. Most genera have many species which are tuberizing, most of which are unknown to man even now. The history, origin and distribution of only a few species which are economically important root and tuber crops and which are commonly used by men for edible as well as medicinal purpose are elucidated in this chapter.

1. Sweet Potato

Exact centre of origin of sweet potato (Ipomoea batatas), and the routes and times for its dispersal to some of its present locations, are still in dispute and are likely to remain so until further archaeological or ethnobotanical evidence is available (O’Brien, 1972).

Bakery Industry

Baked goods have been around for thousands of years. The art of baking was developed early during the Roman Empire. It was a highly famous art as Roman citizens loved baked goods and demanded for them frequently for important occasions such as feasts and weddings etc. Due to the fame and desire that the art of baking received, around 300 BC, baking was introduced as an occupation and respectable profession for Romans. The bakers began to prepare bread at home in an oven, using mills to grind grain into the flour for their breads. The oncoming demand for baked goods vigorously continued and the first bakers’ guild was established in 168 BC in Rome. This drastic appeal for baked goods promoted baking all throughout Europe and expanded into the eastern parts of Asia. Bakers started baking breads and goods at home and selling them out on the streets.

This trend became common and soon, baked products were getting sold in streets of Rome, Germany, London and many more. This resulted in a system of delivering the goods to households, as the demand for baked breads and goods significantly increased. This provoked the bakers to establish a place where people could purchase baked goods for themselves. Therefore, in Paris, the first open-air bakery of baked goods was developed and since then, bakeries became a common place to purchase delicious goods and get together around the world. By the colonial era, bakeries were commonly viewed as places to gather and socialize.^[2] World War II directly affected bread industries in the UK. Baking schools closed during this time so when the war did eventually end there was an absence of skilled bakers. This resulted in new methods being developed to satisfy the world’s desire for bread. Methods like: adding chemicals to dough, premixes and specialized machinery. Unfortunately these old methods of baking were almost completely eradicated when these new methods were introduced and became industrialized. The old methods were seen as unnecessary and financially unsound, during this period there were not many traditional bakeries left.

Bakery is a traditional activity and occupies an important place in food processing industry. The bakery manufacturers in India can be differentiated into the three broad segments of bread, biscuits and cake. About 1.3 million tonnes of the bakery products industry in India is in the organized sector out of 3 millions tonnes, while the balance comprises of unorganized, small-scale local manufacturers. Though, there are sufficient automatic and semi-automatic bread as well as biscuit manufacturing units in India but there are still number of people prefer fresh bread and other products from the local bakery. After entry of Pizza and Burgers’ MNCs in the country, people are changing their tastes also. Today, they are not restricted to bread, cake and biscuits but to other bakery products also. The consumers are increasingly going for newer options with respect to bakery products. With the ventures of few Companies like Britannia, Biskfarm, and Morish etc. competition has increased. Also, the Indian market is witnessing the proliferation of bakery cafe chains in the form of Baristacafe, coffee day, Café Coffee & Monginis etc.

Armed with better technology, know-how and novel ideas, these foreign companies have made rapid inroads into the lucrative market within a very short span of time. Though the demand for bakery products in India has always been on the rise, there is clearly a lack of awareness and the will to break new ground, which has helped global players to gain brownie points while exploring the market in India. The unorganized sector accounts for about half of the total biscuit production estimated at 1.5 million tonnes. It also accounts for 85 per cent of the total bread production and around 90 per cent of the other bakery products estimated at 0.6 million tonnes. The last includes pastries, cakes, buns, rusks and others.

History

Pineapple was discovered a little later in time than expected. It had been a staple of the American diet for years before Christopher Columbus, an Italian explorer, discovered it on November 4, 1493. (www.library.ucf.edu; www. levins.com). That’s when the Guadeloupe Island natives served him and his colleagues this delectable fruit, pineapple. The varieties cultivated at the time were all seedless, and many typical wild cultivars were missing (Collins, 1948), demonstrating the area’s early vegetation. He brought the fruit to Europe. The European travellers were so fascinated by this fruit that they frequently mentioned it in their accounts (Morrison, 1963; Collins, 1960).

It was known as ‘nanas’ or ‘ananas’ by the people of South America (‘ananas’ meant ‘excellent fruit’ in Guarani). People in the area literally cultivated it according to a strict protocol, and they were especially keen to select superior varieties in order to increase fruit yield and quality. They gained a thorough understanding of crop agronomy and production. They also put into practise some of the processing standards that are still in use today around the world (holidayandtraveleurope.blogspot.in). Pineapple wine was made, fibre was extracted, and pharmacological needs such as emmenagogue, abortifacient, antiamoebic, vermifuge, stomach disorders, and poisoning arrow heads were met (Leal and Coppens d’Eeckenbrugge, 1996). In 1980, Antoni and Leal proposed that the pineapple originated in an area further north, between 10° N and S latitudes and 55–75° W longitude, which included parts of north western and eastern Brazil, Columbia, Guyana, and Venezuela. During colonisation, Spanish and Portuguese navigators were instrumental in the distribution and spread of pineapple to all corners of the globe (www.daf.qld.gov.au 2015).

Cashew has a long history as a useful tree but only in the current century, it became an important tropical horticultural crop. Small-scale local exploitation of cashew for its nuts and cashew apples is the pattern for more than 300 years in Asia and Africa. It was not until early years of 20^th century that international trade in cashew kernels began with first exports from India. Although with slow beginning, cashew became an important commercial crop in the last couple of years. In India, use of cashew apples and nuts was started by local people, and accounts from Africa are similar; making cashew wine/liquor possessing a common practice in both Asia and Africa (Johnson, 1973).

Cashew, an evergreen tree, produces both nuts and apples, has become a crop of importance owing to the highly valued kernel and wide adaptability to varying agro-climatic conditions. India is one of the largest producer, exporter and consumer of cashew in the world. Today, cashew has become a crop of high economy and has moved from a crop of waste lands to commercial crop, even in organized sector (Singh, 1998).

The early history of laparoscopy is unknown to many surgeons, but Hippocrates (460-375 BC) in Greece was first to describe endoscopy). He made reference to a rectal speculum. Hippocrates also advised injecting a large quantity of air into the intestines through the anus in the case of intestinal obstruction. He also advocated the insertion of suppository that was 10 digits long. These descriptions suggest that Hippocrates was well aware of ileus with intestinal obstruction and thought of several possible etiologies, including faecal impaction, intussusception, and sigmoid volvulus. Moreover, Hippocrates treated these life-threatening conditions with minimally invasive approaches.

The history of the guava fruit can be traced back thousands of years, and it has a rich cultural and botanical significance. The guava fruit (Psidium guajava) is believed to have originated in the tropical regions of Central America, particularly in present-day Mexico and neighboring countries. Archaeological evidence suggests that guavas were cultivated and consumed by the indigenous people of these regions as early as 2000 BCE. From there, the fruit spread to other parts of South and Central America, the Caribbean, and eventually to other tropical and subtropical regions around the world. Guava holds significant cultural importance in various ancient civilizations. In the Mayan culture, guavas were considered sacred and symbolized fertility (Arévalo- Marín et al., 2021). The fruit was also believed to have healing properties, leading to its use in traditional medicine. The Spanish and Portuguese explorers played a pivotal role in spreading guavas to other parts of the world during the Age of Exploration. They brought the fruit back to Europe, Africa, and Asia, where it quickly adapted to the tropical and subtropical climates. Guava cultivation in Asia can be traced back to the 16th century. It is believed that the Portuguese introduced guavas to India and Southeast Asia (Hussain et al., 2021). The fruit’s popularity grew rapidly in these regions due to its adaptability to various soil and climate conditions. Guavas were introduced to Hawaii in the early 19th century. The fruit quickly naturalized and became a prominent part of the Hawaiian diet. Today, Hawaii is known for its delicious pink-fleshed guavas, and guava-based products such as jams and juices are popular exports (Shigeura & Bullock, 1983). Guava has been recognized for its nutritional and medicinal properties since ancient times. It is a rich source of vitamin C, dietary fiber, and various essential nutrients. Traditional medicine in many cultures used guava leaves, fruit, and roots for treating ailments such as diarrhea, dysentery, and respiratory issues. Guava fruit and trees have also found their way into ancient literature and folklore. In some Indian epics and poems, the guava tree is celebrated for its lush greenery and sweet fruits, symbolizing prosperity and abundance (Reguengo et al., 2022).

Hog-plum also known as wild mango (Spondias pinnata), is native to tropical Asia. A small, aromatic deciduous tree, up to 27m height and 2.5m in girth, with a clear bole of 16m, is found wild or cultivated almost throughout India, ascending up to an altitude of 1500m in the Himalayas; also found in the Andamans. Bark thick, aromatic, smooth, grey; leaves imparipinnate, 20-60cm long, leaflets 5-11, 22-28cm long, ovate-oblong, elliptic or elliptic-oblong, more or less oblique with mango-like smell; flowers whitish or greenish white, polygamous, in large, terminal panicles; fruits in terminal clusters of 10-15, drupes yellow-green or rich olive-green, mottled with yellow and black, smooth, ovoid, 4-7cm long; seeds 1-3, one being perfect, oblong-elliptic. Fruit is extremely sour, even when completely ripe.

6.1 Kinetics of Rumen Digestion

The rate and extent of digestion of dry matter or organic matter in the rumen is regarded as the important parameter to predict voluntary feed intake (Khazaal et al., 1993; Blummel,1994). Voluntary feed intake is responsible for more than 50 per cent of the variations in animal response to the diet (Van Soest, 1994) and with low quality unsupplemented roughages, this can be as much as 93% (Blumme1,1994). Therefore, any parameter of feed evaluation that would indicate the voluntary feed intake would be a useful parameter to judge the quality of feedstuff. The rate of digestion of any feed component can be measured by determining extent of digestion at intervals of time. Therefore, the techniques for determining extent of digestion, such as the rumen in vitro techniques (Tilley and Terry, 1963; Goering and Van Soest, 1970) or the in situ Dacron bag technique have been adopted to derive rate of degradation of dry matter of any particular component of the feedstuff. However, unlike in determining the extent of digestion, wherein the incubation is turned off at one particular time (normally 48 hours), measurement of rate of digestion, requires termination of incubation at several points between the start of incubation and until at least 90% of the potentially digestible dry matter is digested (72 or 96 hours). This generates a large number of samples for analysis.

In gas production technique, since gas produced from digestion of substrate is accumulated in the incubations, measurement of gas at different times of incubation would reflect the extent of digestion at different times of incubation. Therefore, unlike with other in vitro / in situ techniques wherein, digestion is determined from the gravimetric disappearance of feed at different times of incubation, gas production technique offers the possibility of using cumulative gas production at different times of incubation to measure the rate of digestion. Thus, a single incubation of feedstuffs is adequate to measure the rate of gas production.

In his classic book ‘The Ascent of Man’, Bronowski has written, “When I was a young man, we all thought that mastery came from man’s domination of his physical environment. Now we have learned that real mastery comes from understanding and moulding the living environment.” Our Biosphere, the living environment that supports us all, has problems and we humans are mainly responsible. We do not live ‘gently’ on the earth. The seven billion of us require air, water, food, energy, housing and amenities and we have developed the earth to provide them and have also created problems. That problems exist are serious is the bad news. That we are recognizing them and that man has shown ability to organize and grow in ascending order from time to time is the good news.
TECHNOLOGICAL OPTIMISTS OR TECHNOLOGICAL CRITICS
A barrier often divides environmentalists and industry. This is the result of a kind of polarization in the 1970s that forced people to define themselves as other technological optimists or technological critics. The environmental debates have usually advocated environmentally benign, small-scale, relatively “low’ technologies. The “soft path” based on conservation and simple renewable energy technologies was pitted against the “hard-path” based on largely on nuclear, fossil fuels etc. In farming Eco agriculture and Organic farming challenged the intensive use of energy, fertilizers, pesticides etc.
WHAT REALLY IS ADVANCED TECHNOLOGY
For the optimistic proponents of advanced technology, the main danger was that retrealist, anti-technology “prophets of doom” would be causing a collective loss of nerve. To them, it would mean missing an opportunity to get an affluent, supercritical society that would overshoot the limits to growth.

Abstract: Hollyhocks are seed propagated garden annuals with numerous hybrid phenotypes, series (single and bicoloured Halo series), Spotlight, Carter’s Double, Double Triumph, Giant Double Powder Puff, Halo Bush (tricoloured), Halo Mixed (eight colours) and cultivars are available in the world market. Unusual plant height, delayed flowering compared to other winter annuals handicap its popularity. While little genetic information and trait heritability has been established for this crop, breeding continues to produce new variants for commercial production. Gene pool of hollyhock exhibits great diversity. Breeding objectives with high priority include dwarf stature (2 feet height), compact growth, double and large flowered inflorescence, precocious flowering and resistance to leaf rust disease.

Abstract

Overall geological histories of the Quaternary deltas of all over the world have been studied considerably, to understand the evolution, eustatic – isostatic changes, land – ocean interactive phenomenon, resources, environment etc. But tectonic signatures of these deltas have been less studied, though these have significance in understanding the natural resources, environment and evaluation of natural disasters. In this context, as the state of Tamil Nadu is a low easterly gradient plain, all the easterly flowing rivers have developed well evolved geomorphic features related to youthful, mature and old stages. Such old stages of the rivers are marked by the spectacular development of deltas. These deltas of Tamil Nadu have been studied in detail for understanding the tectonics with the help of visibly seen tectonic and geomorphic features in satellite based remote sensing and ground based data sets. The study has revealed that the upper age limit / ages of these deltas are probably of Middle to Late Holocene and the various tectonic and geomorphic anomalies observed in these deltas obviously indicate the tectonic processes/ phenomena that prevailed during Middle Holocene - till date. The Proto Cauvery delta of Chennai region is witnessing ongoing NE–SW sinistral, NW–SE dextral and E–W vertical tectonic activities. The streams in Ponnaiyar delta are showing persistent southerly migration due to the probable ongoing land subsidence along NE–SW faults in the southern part of the delta. The Cauvery river which has originally developed a broad bird-foot shaped – arcuate delta, has undergone a phase of anticlockwise rotational migration and stabilized in the northern rim of the delta as Coleroon river during 2300–750 Y.B.P. due to the ongoing tectonic emergence in the south of the delta almost since the last 6000 years or so. The Vellar river, in deltaic regime, shows northerly migration due to E–W grabening in the northern part of the delta. Vaigai and Manimuttar rivers are again migrating northerly in their deltaic regions due to the probable land arching to the south of their present day flow. Thus, the paper discusses the post deltaic / Middle -Late Holocene geological processes of Tamil Nadu deltas which are predominated by tectonic activities.

9.1 Introduction

Holocephalians are a group of highly specialised cartilaginous fishes that live in the sea. It is structurally similar to Elasmobranchii and Teleostomi. It exists in both extinct and living forms. Previously considered a class of Pisces, Nelson (1984) classified Holocephali as a sub-class.

9.2 Systematic Position

Phylum: Chordata

Scientific name: Ocimum sanctum L.
Family: Lamiaceae
The ‘Sacred basil’ or ‘Holy basil’, Ocimum sanctum Linn. a biennial shrub belonging to the family Lamiaceae, is commonly cultivated in gardens. The Hindus of India worship the species and is traditionally grown in courtyards and temples. The aromatic plants belonging to genus Ocimum is popularly known by the name Basil. Basil was derived from Greek word “Basilica” which means royal plant. Among the Ocimum genus Ocimum basilicum is variously known as Sweet basil, French basil or Common basil. Ocimum sanctum is known as sacred basil or Holy basil which is a very sacred plant according to Hindu belief.
Origin and distribution
Ocimum Sanctum has broad distributions, covering the entire Indian subcontinent, ascending up to 1,800 m in the Himalayas and as far as the Andaman and Nicobar Islands. This plant occupies a wide range of habitats.
Botany
Botanically, Ocimum sanctum is an erect, herbaceous, and softly hairy plant that exhibits extensive branching. It typically grows to a height of 30-75 cm. The leaves are entire, serrate, and pubescent on both sides, while the flowers are characterized by their purplish or crimson hue, arranged in racemes. The fruits of Ocimum sanctum are sub-globose or broadly ellipsoid in shape, slightly compressed, nearly smooth, and exhibit a pale brown or reddish coloration with small black markings. It is a biennial or triennial shrub.

I. General information

A kitchen garden/ nutrition garden is a vegetable garden where the vegetable crops are grown in the backyard of a house or any available space in compound or rooftop of the house, to meet the daily requirement of the family. All the members of the family are collectively involved in a kitchen garden.

For a balanced diet, 300 g of vegetables are to be included in our daily food. But on an average, Indians take only 160 g per day. Hence to fill up the gap, vegetable cultivation not only in farmers’ holdings but also in the home gardens is encouraged.

INTRODUCTION
Agroforestry is a land use option that increase livelihood security and reduce vulnerability to climate and environmental change. Agro-forestry has many potential, such as to enhance the overall (biomass) productivity, soil fertility improvement, soil conservation, nutrient cycling, micro-climate improvement, carbon sequestration, bio drainage, bio- energy and biofuel etc. There are many agroforestry systems practiced in India from time immemorial, but the potential of home gardens and their socio-economic significance is very well documented.   Home gardens represent land use systems involving deliberate management of multipurpose trees and shrubs in intimate association with annual and perennial agricultural crops  and livestock within the compounds of individual houses (Fernandes and Nair 1986). Home gardens can also be called as Multitier system or Multitier cropping. Home gardens are highly productive, sustainable and very practicable. Food production is primary function of most home gardens on sustenance basis.

Introduction

Food and nutrition security is the basic requirement of human development. Among the ten global burden of diseases, six are connected with diet related factors. Food and nutrition security is also closely related to other factors like socio economic status, geography and demography. Asia, Latin America and Africa hosts world’s most of the undernourished population. Among these regions South Asia is considered as one of the hotspots of malnutrition, in which India is the major contributor. Fifty seven percent of population cannot afford healthy diet in South Asia.

Over the centuries of remarkable economic growth in India concomitant reduction in under nutrition has not been witnessed and this dilemma is called Indian enigma (Gillespie et al 2012; Sengupta 2019). In India among the different socio economic categories, undernutrition has highly been manifested among SC and STs (Gillespie et al 2012; NNMB 2009).The reasons of food and nutrition insecurity are directly linked to remoteness, dire poverty and dysfunctional food security programmes (Khera 2011; UNICEF 2014). Poor and landless among them are mostly falling prey to chronic food insecurity. Coupled with reduction in locally available dietary inputs, rising food expenditure also compel poor to cut back the quantity and resort to low priced calorie dense food (Smyth & Sweetman; 2010). Therefore, poor people’s diet assume to fraught with starch, which leads to nutritional imbalances and resulting in to various lifestyle diseases like diabetics among them. This situation necessitates the need of local, sustainable household food production through home nutrition gardens. Many studies testify the impact of household level food crop cultivation in addressing malnutrition. Kuhnlein & Raceveur 1996; Pimbert 2009; Vira et al 2015 argues inadequate diets are associated with the “delocalization of food supply” and disruption in existed food systems. Therefore, in general literatures on agriculture and nutrition elicits the positive correlation between cultivating food crops and nutrition security (Gillespie et al 2012; Hossain et al 2016; Viswanathan et al 2015). In this context, home nutrition garden programmeassumes greater significance in countering malnutrition among Paniyan community in Western Ghats region of Wayanad district of Kerala.

ABSTRACT

Homegardens are traditional agroforestry systems present throughout the northeast India especially in foothill region. The high diversity and the intensive care that is given to the homegarden in and around Arunachal Pradesh results in a unique combination of high levels of productivity, stability and sustainability of the system. The homegardens studied here were vertically distributed in four different layers viz, floor, middle, sub-canopy and canopy. Such stratification has given rise to the distribution of a variety of species based on light requirement in the system. Density and diversity index of tree species in the homegardens were highest in Harmutty in the foothills (468.5 plants ha^-1 and 1.17 respectively), whereas lower values were recorded in Ziro in the upper elevation (16 plants ha^-1, 0.651 respectively). Soil nutrients were greater in Harmutty, followed by Doimukh, Nirjuli and then Ziro. Maximum plant detrital (litter and fine roots) biomass and their subsequent decomposition in the homegardens of Harmutty (10185.67 kg ha^-1) might be the probable reason for the efficient nutrient cycling and generation of more available nutrients.

Many human illnesses are contacted from animals and plants; and are also due to imbalance in the environment. Mental, emotional and relational symptoms seen in humans are absent in animals. Nevertheless, careful observations on the behavior of the animal and its relation with others may play key role in homeopathic prescribing in animals. No doubt the use of homeopathy in animals is challenging. Homeopathic treatment of pet animals has many similarities with homeopathic treatment of babies and children such as non verbal communication, the socialization and the relationship with third parties (owners in case of pets and parents in case of children).There are many prescribing strategies in veterinary homeopathy.
