Introduction

Food and nutraceuticals are obtained from various agricultural resources available in this planet. Many types of bio-active compounds are available in small quantities in the plants and animals which are evidenced to improve performance of various organs, increase in immunity and cure for some diseases. Last decade evidences several advancements in developing phytochemical formulations which can be used as a cure for many diseases as well as helps in boosting immunity in human being. Such materials exist in different form, structure and chemical compositions. Examples of such chemicals are phenolic and organosulphur compound (Pascall 2011). The vegetables, fruits and seeds are used without further processing. Some plants are subjected to cooking before its consumption. Many industries are carried out extraction of bioactive compounds and developed products in the form of tablets, powders and liquids which are available in the market. In order to make commercial process more economic and feasible, long term storage of plant residues (Raw materials) as well as the prevention of the extracts emerges as essential requirement for the industries. Moreover, the products requires suitable packaging solution to increase its self-life, preventing it from the influences of environment, and to make viable solution for easy access which makes it more user-friendly. Suitable packaging solution is required for mainly the three reasons: (i) prevention. (ii) protection and (iii) presentation. Prevention is required in-order to avoid deterioration of the packaged items due to microbial growth, loss in moisture and enzymatic action. Protection is required for the purpose of protecting the packaging materials from the contamination as well as from the environment impact and rough handling. Presentation is equally important to provide it an aesthetic look to make it more approachable to the consumers. Moreover, packaging also offers “labelling for easy identification, warnings, instructions, and nutritional information, ease of transportation” (Pascall 2013).

Food packaging is an essential technique for preserving food quality and minimizing food wastage. It is a scientific technique of containing food against physical, chemical and microbiological contaminants. In addition package also display the product in most appropriate manner and provide product information to the consumers while at the same time allowing convenient handling and efficient distribution. The packaging of meat and meat products are particularly important because meat is highly nutritious food and provides good medium for the growth of micro-organisms. Meat and meat products are also susceptible to bacterial growth due to their high water activity. Exposure of meat and meat products on atmospheric temperature and sunlight leads to various types of deteriorative changes. For example when cut meat surfaces exposed to ambient air provide excellent breeding grounds for most bacteria. Minced meat is even more at risk due to the large exposed surface area. Packaging provides protection of food against external and internal factors but once food gets deteriorated it can not be controlled by packaging. For this reason rigorous hygiene in all processing and pre-packaging steps is vital for packaging of perishable food items like meat and meat products.

The packing methods practiced by nurserymen for transport of nursery plants to distant places in India are neither uniform nor efficient. In different parts of the country, various practices are followed which are claimed to have been evolved by long experience of the local nurserymen. They vary according to nature of the plant, the season and the cheapest packing material available at the time of packing.

In many parts of the country, citrus nurserymen uproot plants, tie them in large bundles (with or without soil), keeping the plant tops exposed to air and roots tightly packed or tied in the gunny cloth. The pomegranate and guava plants prepared by air layering are packed as such if they are not already potted in small pots.

Many nurserymen pack the rooted or newly lifted plants in a ball of sticky clay. The ball of earth is then covered with grass and tied as firmly as possible, thus securing the roots against drying. A number of plants, thus prepared, are filled closely in light locally knit bamboo baskets. The baskets are covered thinly with coconut leaves as protection against injury during railway shipment. Mango grafts in pots are packed in light baskets with some cushion of grass to reduce the impact while loading and unloading the parcels on their long journey by rail and road.

Some nursery men use large baskets, woven out of coconut leaves with limp walls or sides. Plants such as coconut, chikoo, guava, mango are packed tightly in these baskets and shipped by truck or rail. This packing is done irrespective of plant containers such as pot or a ball of earth, with or without grass covering. The plants packed in all such fashions are usually damaged and some of them do not survive, unless care is taken during or after transplanting them in the permanent places. For better success, it should be seen that the roots of grown up plants do not get irreparable injury while removing from the bed or the pot. During transport, loss of water by transpiration should be kept at minimum, while the plants are awaiting dispatch or delivery at the railway platform, precaution should be taken against pilferage or damage by animals.

From the earliest time, man had to conserve and preserve his food, so that surplus at harvest following a successful crop can be stored for use throughout the year. Prime agricultural products in general and more so with fruits and vegetables which are being processed world wide or preserved to a more stable form so that they can withstand transport, handling and storage over a long period. As civilization developed, man learnt to preserve fruit and vegetable products with salt, spices and by drying , smoking or cooling which could extend their shelf life. Later by experience, he learnt that by protecting it from environmental factors such as air, moisture and light, the shelf life of these processed products could be further increased. He tried to keep them dry and covered to protect from insects and rodents. As with solid foods, primitive man experimented with beverages also. It is likely that the first beverage known to him after water was fruit juice. This undoubtedly led to the discovery of wines made from the fermented fruit juices. Later on, preservation methods and development of packaging materials underwent drastic changes.

The semen storage technology and glass ampoules were earlier developed in USA and French, Danish and West Germany introduced straw technique and in the mean time Japanese scientists developed pellet freezing method. 

1. Ampoule method 

The diluted semen is filled in ampoules after labeling, sealed, frozen and preserved in liquid nitrogen. For insemination, the ampoule is thawed in warm water of 37^ºC until liquidation then ampoule is cut and semen is drawn into glass catheter with the help of a sterile syringe and used for insemination. In this method, semen may not be contaminated and identification of semen is easy. However, the semen is frozen in a larger volume so the freezability and fertility are less and it requires more storage space in cryocan. About 8-10% of semen is lost while thawing, loading and insemination.  Use of glass catheter for insemination is risky because chances of breaking and chances of injury to cow or inseminator and passing of catheter in the cervix.

The packaging requirements for food products are as varied as the foods themselves, with each category necessitating unique materials and design considerations to ensure product quality, safety, and consumer satisfaction. Packaging serves as the first line of defense against environmental factors like moisture, light, oxygen, and microbial contamination, which can significantly impact food stability and shelf life. The role of packaging extends beyond mere protection; it also contributes to preserving texture, flavor, and nutritional value, making it a crucial factor in the overall success of a food product. Chapter 10 delves into the specialized needs of different food types—such as bread and bakery items, snacks, dairy products, coffee, and carbonated beverages—analyzing the packaging materials, structural designs, and technologies required to maintain product integrity. The food industry faces the complex challenge of balancing protective packaging with considerations for sustainability, consumer convenience, and regulatory compliance. This has led to the evolution of advanced

The packaging requirements for food products go beyond mere containment. Effective packaging must serve multiple functions, such as protecting food from physical and environmental hazards, providing convenience to consumers, and acting as a medium for communication and branding. Each requirement is essential to ensure food quality, safety, and longevity, as well as to meet consumer expectations and regulatory standards. As food products vary in their characteristics and shelf-life requirements, packaging must be tailored to suit these specific needs while also considering factors like transportation, storage, and market positioning. This chapter delves into the fundamental requirements of food packaging, examining the functional roles that packaging plays across various product categories. By understanding these requirements and functions, we can appreciate the complexity of designing effective food packaging that fulfills multiple roles in the modern food supply chain

Product Characteristics and Packaging Requirements:

The key raw materials for sugar confectionery are sugar (60 - 65%), glucose, citric acid and flavoured essences. Confectionery is hygroscopic in nature and requires protection against the ingress of moisture, and exposure to high temperature (as far as possible).

A candy or confectionery product may be adversely affected by many things. Hard candy, brittles and crunch products are most sensitive to moisture and absorb water vapour fairly rapidly from the atmosphere. Various gums are less sensitive while some creams tend to lose moisture considerably.

12.1 Active Packaging: Types, Mechanisms, and Applications • Antimicrobial Packaging: This type contains substances such as organic acids, enzymes, or metals like silver nanoparticles to prevent microbial growth, thus prolonging shelf life ( Ma, Q et al .2021) • Oxygen Scavengers: These absorb oxygen to minimize oxidation and spoilage, often used in snacks, baked goods, and meats. • Moisture Control: Packaging features absorbent materials or humidity regulating films to keep moisture levels optimal, particularly in fresh produce. • Ethylene Scavengers: These helps slow down the ripening process in fruits and vegetables by reducing ethylene gas levels. • CO? Emitters: These generate carbon dioxide to inhibit microbial growth, particularly useful in certain food products (Yildirim et al., 2018) 12.2 Mechanis

Introduction

“The World Packaging Organisation’s (WPO) slogan, “Better Quality of Life Through Better Packaging”, sumps up the important place that packaging occupies in a modern economy.

As the economics of many countries are increasing, the consumers have started using more processed food. As a matter of fact global food processing and packaging business has reached to multi trillion dollars. In today’s world of global markets and stiff competition in every product along with increasing consumer demand, it becomes imperative for companies to explore ways to improve their productivity in terms of maintaining safety, using sustainable packaging materials, implementing flexible and standardized technology, and adopting proven management. Towards this end, companies have been striving to improve the efficiencies of their operations through improvements in the processes. Reducing wastes and shortening lead times becomes all the more imperative in the food industry due to the perishable nature of the product. Moreover, recent advances in technology such as Radio Frequency Identification (RFID) and nano-materials afford companies greater opportunities to streamline the processing, packaging, and manufacturing schemes.

26.1 Introduction
Developed nations’ packaging sector has achieved great advancement. The advent of innovative marketing strategies such hyper markets and selfservice outlets has pushed the packaging technologies in these nations to unprecedented heights. The evolution of appliances and packaging tools as well as the introduction of fresh and better packaging materials has happened holistically. In nations like India still in development, packaging is still in its infancy. Packaging any product is the arrangement of the most appropriate containers and components to safeguard, move, label, and identify any good.
26.2 Packaging
Packaging is putting an item into a protective wrapping or container for use or storage. The package serves three purposes: it stores, shields, and merchandising tool. For the safe delivery of the product through the several phases of manufacturing, storage, transportation, distribution, and marketing, it is a necessary link between the manufacturer and ultimate customer. Fresh, sound and easy form of milk delivery depends on protective packaging to minimise losses and withstand the challenges of climate change, transit, handling etc.
1. To contain the product: The package should be big enough and built with suitable elements to stop spoiling and leaks. It should be sturdy enough to withstand handling, shipping, and storage difficulties as well as closely matched with the product.
2. To protect the product: Packaging seeks to protect the product from microbiological activity, heat, light, moisture, oxygen, evaporation, etc., therefore preventing contamination, loss, damage, or degradation.
3. To help in selling the product: Easy dispensing, reclosure, disposal, and possible reuse should be made possible by the packaging form, therefore helping the marketability of the product.

Packaging is an important consideration in vegetable and fruit market. The use of properly designed containers for transporting and marketing of vegetables is significantly reduce losses and maintain their freshness succulence and quality for longer period. Packaging also provides protection from mechanical damage and undesirable physiological changes and pathological deterioration during storage, transportation and marketing.

Many vegetables are transported in gunny bags and bamboo baskets. Packaging material such as polythene films, paper boars, and boxes lived with polythene and other materials can effectively prolong the shelf life of vegetables. By using plastic films vegetables can be protected from dry air. Polythene packaging provides modified atmosphere and consequently reduces decay, softening, and loss of solids. The thickness and permeability to CO₂, O₂ and water vapour of films needs to be standardized for each vegetable.

1. Introduction

Packaging is the integral part and cornerstone of food processing industry. The development of food processing industry goes hand in hand with advancement of packaging technology. Packaging Institute International has defined packaging as “enclosure of products, items or packages in a wrapped pouch, bag, box, cup, tray, can, tube, bottle or other container form to perform one or more of the following functions: containment, protection, preservation, communication, utility and performance”. Lockhart has defined packaging as “a socio-scientific discipline that operates in society to ensure the delivery of goods to the ultimate consumer of those goods in the best condition intended for their use”. Food packaging technology has came a long way from use of anything in hand for wrapping up a product to becoming a key element in product development and design.

23.1 Dry Flower Packing

Careful packing is one of the most important aspects of any product. Dry flower packing is the simplest way to capture the essence of summer flowers till long. Dry flowers should be packed nicely to avoid any damage. They should be packed alone in appropriate sized carton loosely cushioned with paper.They should be packed in a manner to keep them away from direct sunlight leaving some room for air. Packing material should be stable and firm to hold the dry flowers well without any damage during storage or transportation. Dry flowers can be packed in a variety of ways: in poly bags, window box, cardboard box, or in a sachet.

The packing and transportation of fish and shellfish seed demand meticulous care to preserve the health and survival of juveniles. This process involves the use of suitable containers, maintaining sufficient oxygen levels, and regulating water temperature and quality to minimize stress and reduce mortality rates. In aquaculture, it is common to transport hatchlings, fry, and fingerlings of cultivable species. Occasionally, mature broodstock must also be moved to facilitate seed production. In certain regions, transporting live market-sized fish from capture sites to markets is a highly organized industry, though the focus here is primarily on the transport of brood fish and seed for aquaculture purposes. Historically, fish seed has been transported in earthen pots, often carried manually or suspended using slings from collection points to nurseries or markets. These traditional methods, while long-standing, typically result in significant mortality. However, advancements in live fish transport have emerged due to a better understanding of fish physiology at different life stages—hatchling, fry, fingerling, juvenile, and adult—and the identification of key causes of mortality during transit. Although traditional practices may not yield high survival rates, they still offer value, particularly in rural aquaculture settings where advanced technology may be impractical. Modern transportation methods are based on two interrelated approaches: understanding the internal physiological needs of fish and managing the external environment in which they are transported. Effective integration of these approaches—such as controlling oxygen levels, pH, and ammonia in transport media, and preparing fish through conditioning or pre-transport fasting—can significantly boost survival.

Introduction

Packing and transportation forms an important component in fish trade whether live fish, fish seed, fresh fish, iced fish or dried fish. There are few reasons necessitating packing and transportation.

    ·    The movement of fry/juvenile for stocking into farms or restocking into natural environment.
    ·    The movements of fish to markets for sale selling/consumption.
    ·    The movements of ornamental aquarium live fish for trade.
    ·    The movement of aquatic animals for research purpose.

Most of the horticultural produce is of perishable nature and must be protected from postharvest losses, which start from the field itself. Therefore, adoption of proper packing house operation plays a very crucial role in minimizing postharvest losses

Although, we have reached new heights in the production of fruits comparable to China, Brazil and USA and in vegetables to China, yet we are far behind in postharvest management of these perishables, primarily due to lack of appropriate infrastructure. Test studies conducted in Australia have indicated that the distribution cost of perishable horticultural produce is assumed 5 to 9 times, the production cost. Further, packaging accounted for 25-50% of the wholesale price of fruits and vegetables. In India, huge losses of horticultural produce (25-30%) after harvest are encountered mainly due to non-existence of packing house concept.

Packing house operations essentially begins with the use of proper field containers, field transport, temperature protection of harvest produce, sorting, sizing, grading, packing, which are essential preparatory steps to storage, shipment and subsequent marketing. Depending on the kind of produce, additional activities viz. degreening, curing, washing, ripening, waxing, precooling etc. are done. The sequence of activities varies with the crops. A considerable quantity of postharvest losses of horticultural produce could be minimized by adoption of various packing house operations described below:

Early research in field of semen storage and delivery systems was conducted in USA. The straw technique for the storage of frozen semen was evolved by work of French, Danish and German workers whereas the pellet system of storage of semen was devised by Japanese scientists. The different packing systems of frozen semen are:

    9.1    Ampoule method
    9.2    Pellet method
    9.3    Straw method

9.1 Ampoule Method
In this method the semen is placed in a glass ampoule and is subsequently sealed and frozen in liquid nitrogen. The ampoule is thawed just before insemination and is then cut open. The semen is withdrawn into glass catheter and used for AI. Since the ampoule is sealed there is no risk of contamination during storage. The relevant details can be marked on the ampoule.

Various systems were developed to take produce from field to consumer and selection of a particular method depends on several factors, including perishability and value of crop.  One method is to harvest the crop and take it to a packhouse for various unit operations like grading, cleaning, post-grading treatments, and packing for transport and marketing. When deciding upon where to locate a packinghouse, access to field and market point, adequate space for vehicles to enter and leave  packinghouse and ease of access to labor will all be considered.
 
In the simplest packinghouse, produce is delivered in picking containers, immediately after harvest, directly to packers.  Packers then sort, grade, size and pack the produce directly into appropriate transport containers. In this case, each worker must be aware of produce defects, grade and size requirements, and packing methods.

Introduction

Pain management in poultry is an important aspect of animal welfare and overall production efficiency in the poultry industry. Poultry birds, such as chickens and turkeys, can experience pain due to various reasons including routine management procedures, injuries, and diseases. Managing pain in poultry is crucial not only for ethical reasons but also because pain can lead to decreased productivity and increased susceptibility to diseases. For the better management First step is identification of pain in birds which can only be possible with the thorough knowledge of their behaviour. Second step is the selection of appropriate analgesics and their dosing’s as there are various species of birds. Commonly used analgesics for birds includes, NSAID’s, opioids etc.

1. Routine Management Procedures: Many routine procedures in the poultry industry, such as beak trimming, toe clipping, and wing clipping, can cause pain and distress to birds if not done properly. Beak trimming, for example, is often performed to reduce feather pecking and cannibalism in crowded conditions but can cause acute pain if not done correctly. Proper techniques and pain management strategies must be employed during such procedures to minimize pain and distress in birds.

Palaeontology is the science that deals with the life past geological periods. It is just the opposite of neontology which deals with the systematics of recent organisms. Fossils are the remains or parts of animal or plants that lived thousands of years ago which have turned into rock. They are preserved traces of living organisms in the earth crust.

Fossil History of Insects

Occurrence of insects in fossilised state provides a clear idea of the main order of insects. The oldest known insects’ fossil appears to be of Apterygota and blattids seem to be the oldest living insects, which have almost lived without undergoing large scale evolutionary changes from the Carboniferous to the present day.

Some of the earliest apterygotes might have developed from the Permian or lower Carboniferous. The richest collection of fossil insects is from the vegetable deposits like coal, lignite peats and in amber entangled in the raisin. Most of the insects are known only through their wings, resulting in the study of venation. However, the amber fossil of Miocene presents a clearer picture. The best known epoch is undoubtedly the Permian while Triassic provides richest discoveries of the insect fossils.

The remains of animals and plants of past ages preserved in the rocks are known as fossils, the study of which forms the subject of Palaeontology. The conditions for an animal or plant to become a fossil are firstly it must possess skeleton of some kind or some hard parts, since the soft parts are decomposed rapidly, secondly the organism must be covered up by sedimentary layer, otherwise it will soon crumble to pieces.

5.1 Modes of Preservation of Fossils

The conditions in which fossils occur depends, on their original composition and on the material in which they are embedded. The chief types are as follow:

5.1.1 The entire organism preserved

Occasionally the soft parts of the organism are preserved as well as the skeleton, the whole having suffered very little change. Instances of this are the woolly rhinoceros and mammoth found frozen in the mud and ice in Northern Siberia. Insects encased in fossil resin, known as amber, are found in the Oligocene beds in the Baltic shores of Persia, but the soft part of organisms are rarely preserved.

5.1.2 The skeleton preserved almost unchanged

Sometimes where the skeleton alone is preserved, it remains almost in its original condition, except that it has lost its organic matter. Thus the shells in the Pliocene beds of England differ from living ones only in being lighter, more porous and generally colourless. In some instances a certain amount of mineral matter, such as carbonate of lime, has been added to the skeleton, making it heavier and more compact.

Characters

Palaeoptera world derive from New latin word pale means old and ptera means wings

Two order i.e Ephimeroptera and Odonata comes under this grops because wings can not fold over abdomen at time of rest.

Palak or spinach beet or beet leaf, Beta vulgaris var bengalensis under the family Amaranthaceae (previously under Chenopodiaceae) (Chromosome No. 2n = 2x = 18) is one of the most common leafy vegetables of the tropical and subtropical regions of the world. Its tender, soft and succulent leaves are used as a leafy vegetable. It is a rich and cheap source of β carotene, iron, essential amino acids, ascorbic acid, thiamine, riboflavin, pyridoxine, minerals like, calcium, iron, phosphorus, magnesium, potassium and zinc and fibre. It is very common vegetable in India, particularly in eastern and northern plains of Uttar Pradesh, Bihar, West Bengal, Rajasthan, Punjab and Haryana. It is also grown in Maharashtra, Gujarat and Madhya Pradesh however, it is not common in southern states.
Origin, domestication and adaptation in India
Palak originated from Indo-Chinese region. The Romans used this crop as food for humans and animals. The crop was introduced to USA in 1800 AD (Campbell, 1976). However, it is not known when it was introduced into India. Mentioning of palak in the medical treatise, Charak Samhita, c. 600 BC is the testimony of its long history of cultivation in India. Perhaps it was first cultivated in Bengal. In India, earlier improvement through natural selection by the farmers might have been in the direction of larger succulent leaves, late bolters and ability for regeneration after repeated cuttings. However, despite such a long history of cultivation genetic variability recorded in this species is not wide enough, commensurate with outcrossing breeding behaviour.

1. Introduction

Our Indian traditional medicine depends on herbals which always played an important role in the health problems of many countries. In India, the tribal people are using variety of herbals for effective curing of various ailments. These plants are often used by the local people of that area for treatment of various diseases. Ethnomedicinal studies have offered immense value and opportunities for the development of new drugs. Living close to nature, traditional societies have acquired unique knowledge about the use of wild flora and fauna, most of which are unknown to the people who live away from such natural ecosystem as forests and hills. The hills have been the sources of medicinal plants since the time man realized the preventive and curative properties of plants and started using them for human health care.

Tribal people throughout the world, including India, have developed their own cultures, customs, religious rites, taboos, legends and myths, folk tales, medicine, food, etc., They are the repository of accumulated experience and knowledge of the indigenous vegetation; this can be utilized in tribal development. These days greater emphasis is being laid on this traditional knowledge and on using it in the “bioprospecting” of natural products as a new source of food and medicine.

MATERIALS AND METHODS

The fish hosts were collected from the study area and brought to the laboratory for parasitic examination. The external body surface as well as the internal body organs were thoroughly examined for the parasites. The collected acanthocephalan parasites were washed and relaxed in normal saline. Then the specimen was fixed and preserved in AFA (alcohol-formalin-acetic acid) solution. To facilitate identification of the worms the parasites were cleared in lactophenol and mounted in glycerine jelly. Diagrams were made with the help of camera lucida and measurements were taken with ocular micrometer. All the measurements are in millimetres. The collected parasites were identified following Yamaguti (1963) and Bhattacharya (2007).

A family of 183 genera and over 2,600 species distributed widely in tropical and sub-tropical regions of the world and a few also in warm, temperate regions. About 28 genera and over 95 species have been reported from India. Chief genera along with the number of their total reported species and the common names of them are Calamus (300, cane palm), Chamaedorea (130), Areca (54, betel nut plam), Coccothrinax (50, Biscayne palm), Copernicia (30, wax palm), Raphia (30, wine palm), Sabal (25, cabbage palm), Phoenix (17, date palm), Roystonea (17, Royal palm), Metroxylon (15, sago palm), Phytelephas (15, ivory-nut palm), Caryota (12, fish-tail palm), Elaeis (2, oil
palm) and Cocos (1, coconut palm). Selected Indian Genera Araca, Borassus, Calamus, Cocos, Nypa, Phoenix.
Economic Importance
Palm family, supposed to be second in importance to Poaceae, is used for food, oils, shelter, coconuts, copra, dates, clothing, etc. As many as 801 uses of only Borassus flabellifer have been mentioned in one ancient Tamil song. Cocos nucifera (coconut Fig. 45.2) is another such plant of this family whose almost every part of entire plant body is utilized in some ways or other, i.e.

Introduction
Palmarosa/Roshagrass (Cymbopogon martinii var. motia): It is a tall perennial tuffed hedge grown naturally as well as commercially in the old world tropics and sub-tropics of India. It occurs in open scrub forests in parts of MP, Maharashtra and AP, where it is commercially collected and distilled for its oil. It is also sporadically found in Karnataka, TN and part of UP. The herb along with flowering tops and foliage, on distillation yield a colourless to pale yellow essential oil with sweet scented\ rose-like aroma, containing high geraniol; and used in cosmetics, toiletry and perfumery industry. Concerted efforts during last two decades to develop better cultural practices and development of improved varieties, the area has expanded all over the central, western and southern states of India. This crop is commercially grown in Indonesia, East African countries, Cuba and Brazil. At present, the total oil production is estimated to be around 300 tonnes annually, and two-third (200t) of it comes from cultivation.
Ginger grass (Cymbopogon martinii Stapf. var. sofia): This is another form of roshagrass. Its distribution is overlapping in forests with the ture palmarosa grass, although it has preference for more moist-substratum. Both the forms are morphologically identical in field except their odour when leaves are crushed. Ginger grass has dense tuft and more luxuriant growth, but produces shorter inflorescence and more tolerant to the stagnating water. It crosses freely with palmarosa in nature, producing many intermediary forms.

I. General information

The nature of roots

The roots of palms are usually tough and thick, although slender and wiry types are existing. Some roots creep over the soil’s surface, while a few palms even develop aerial roots that may eventually make them appear to be growing on stilts.

A few palms develop aerial roots at or near the base of the trunk or stems. These include Crysophila warscewiczii (Rootspine palm) and Clinostigma exorrhizum. Other palms with aerial roots include Pinanga aristata, Verschaffeltia splendida (Seychelles stilt palm) and Socratea exorrhiza. Some of these develop into stilt or prop roots, which often form a cone and give the palm extra support, they usually occurs on plams native to wet soils and humid conditions, whereas the base of the palms is at risk from decay. Indeed, in a few instances, the lower part of the trunk withers and the palm is entirely supported by these roots.

An unbranched evergreen tree of tropical and warm regions with a crown of very long feathered or fan-shaped leaves and typically having old leaf scars forming a regular pattern on the trunk. Palms have great ornamental value and are planted in the garden for special effects.

Palms are native of tropics and belong to Palmae or Arecaceae family. They are varied in forms, size and habit of growth. Palms do not increase in thickness and also do not show any distinction in bark wood and pith. Flowers are produced on spikes that hanged gracefully in many species. Inflorescences are highly diverse from large panicles with many orders of branching to simply spikes. Flowers may be bisexual or unisexual borne either on the same plant or on separate plant. Whereas, some palms are polygamous.

Palmyra (Borassus flabellifer L.) is a tropical dioecious palm adapted to arid zone tracts. Though it is a versatile plant which yields many edible and non-edible products it is a less exploited species. It is used for sap, fruit, seed, leaf and fiber and timber products. From nutritional point of view, fruit pulp and seed shoot flour are the most important.Successful promotion of these as foods for general consumption depends on subjecting the fruit pulp to a debittering process, and the seed shoot flour, to initial detoxification processes (Thabrew and Jansz, 2004). Palmyra palms are the most numerous palms in the world after coconut palm (Fox, 1977). Despite this, they are the least studied of all the palms.

Botanical Name: Borassus fabellifier
    ·    Borassus flabellifer - Asian Palmyra palm/Lontar palm/Doub palm/Sea Coconut (Southern Asia and Southeast Asia)
    ·    Borassus aethiopum - African Palmyra Palm (Tropical Africa)
    ·    Borassus akeassii - Ake Assi’s Palmyra Palm (West Africa)
    ·    Borassus heineanus - New Guinea Palmyra Palm (New Guinea)
    ·    Borassus madagascariensis - Madagascar Palmyra Palm (Madagascar)
    ·    Borassus sambiranensis - Sambirano Palmyra Palm (Madagascar)

The palmyrah palm exists both in the wild as well as in cultivation, ranging from sea level about 800 amsl. It is usually grown in seasonal tropical or subtropical climates on sandy soils. It is a very adaptable palm, however, growing well in dry areas and is quite drought resistant. It also grows in per-humid areas and survives water logging quite well. The worldwide distribution of natural and cultivated populations of the palmyrah shows that it occupies a band on either side of the equator and extends laterally over a considerable girth. The country wise distribution of the palms are Mauritania, Senegal, Mali, Gambia, Guinea-Bissau, Guinea, Ivory Coast, Upper Volta, Nigeria, Gaban, Congo, Sudan, Tanzania, Madagascar, Saudi Arabia, Iraq, Iran, Pakistan, Bangladesh, Sri Lanka, Myanmar (Lubeigt, 1977), Thailand, Cambodia, Malaysia and Indonesia (Kovoor, 1983). In India, the palms are wide spread in Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, Maharashtra, Odisha, Madhya Pradesh, Bihar and West Bengal.  Isolated patches are also seen in Assam, Gujarat and Uttar Pradesh (Anonymous, 1948). The palmyrah is considered as a slow grower and the growth rate decreases in regions of higher altitude (Tjitrosoepomo and Pudjoarinto, 1982).

10.1. Origin and distribution

• Native to the tropical Africa and grows in the Nepal, India, Bangladesh, Sri Lanka, Cambodia, Laos, Myanmar, Thailand, Vietnam, Malaysia, Indonesia and the Philippines.

• Palm is widespread in Tamil Nadu, Kerala, Andhra Pradesh, Telangana, Odisha, West Bengal, Bihar, Jharkhand, Karnataka and Maharashtra.

• In Tamil Nadu, it is present in Tuticorin, Tirunelveli, Thenkasi, Virudhunagar, Ramanathapuram Madurai, Theni, Salem, Namakkal, Kancheepuram, Chengalpattu, Tiruvallur, Villupuram, Kallakurichi and Cuddalore districts.

• Palm is dioecious in nature.

• Palmyrah was declared as “State Tree of Tamil Nadu” by the Government of Tamil Nadu.

The bio-degradation process dates back to time immemorial when some wild ruminant animals were spotted feeding on the tree –woods in South Chile. The natives of this place called this feed as “Palo Podrido (Huempe)”, meaning – ‘animal feed’, as opined by F. Zadrazilof Germany. Later on, it was found that thiswood was actuallydegradedbycertaintypes offungi undernatural conditions and decomposed to Spent-wood, which turned out to be the animal feed. The scientists started working on these fungi as well as this type of process. Lately, the fungi were found to be belonging to higher basidiomycetes class, called: White-rot-fungi. They mainly degraded lignin of the wood, however cellulose and hemicelluloses to a limited extent only.

But, surprisingly it was found that the digestibility and crude protein content increased to a considerable extent. Later on, the scientists started working on spent-straws too. The cereal straws (lignocellulosics) constituted a staple-feed (basal) in the developingcountries for theseruminantanimals. But, thepresence of lignin (a biological plastic) limits the utilization of these cereal straws in the rumen eco-system. Thus, the concept of SolidState Fermentation (SSF) sparked into this type of investigation. Some examples of such white-rot-fungi were: Pleurotus ostreatus, Coprinus cineus, Sporotrichum thermophile, Phanerochaete chrysosporium, Polyporous berkeleyi, Neurospora crssa, Alternaria tenius to name a few. Some examples of substrates upon which such types of fungi grew for SSF were: wheat straw, paddy straw, paddy husks, ground nut shells, sugarcane bagasse, barleystraw, sunflower stalk, aspen wood, birch wood, saw dust etc. The resurgence of interest in the use of straw from cereal and grain crops as animal feed had been witnessed in early nineties to maintain the performance of animals. Following were some of the variations undertaken by different scientific groups:

1. Introduction

Among the various well associated morphological units in plants, the reproductive units demand maximum protection which is achieved in pollen grains (also in spores) by encasing the germplasm with a well organized wall with a unique structure and ornamentation. Apart from its functional significance, the wall bears important characteristics which are of immense diagnostic and phylogenetic values. The morphological diversities in pollen and spore organization are greatly exemplified in the vascular plants. The term ‘Palynology’ was coined by Hyde and Williams in 1944 for the science of pollen studies, which include the study of pollen as well as spores. Although some investigators tend to limit the scope of palynology to morphological investigations but others include pollen analyses of peats, coals, honey, and rocks as well as the resulting conclusions drawn from this information, and in a wider sense it is also connected with the pollen chemistry.

The wall of pollen and spores is a very peculiar substance which is resistant to the destructive action of corrosive acids and alkalis and is readily preserved in nature under suitable conditions. The shape, size, and ornamentation or sculpturing of pollen has been the subject of study since the invention of the microscope. Pollen morphology is therefore greatly utilized in interpretation of ancient floras, for determining authentic species phylogeny, distribution and climatic conditions under which they grew, based upon the pollen content of the matrices. Pollen which lodges in moss tufts and lichen mats, or falls in water and gradually sink, or those that fall on sphagnum and clays particularly under anaerobic conditions, are well preserved. This pollen is not destroyed in the transformation of peats to lignite or clay in shale and thus has been preserved for hundreds of thousands of years.

During the present century pollen morphological studies are substantiated and elaborated magnanimously with the aid of Electron microscopy. The surface configuration and finer details are being accurately analyzed for their proper application in plant taxonomy as well as in microfossil diagnosis.

In flowering plants, each anther has four numbers of pollen sacs. Two anther lobes contain 4 pollen sacs in which pollen grains are produced. Pollen grains develop from the diploid microspore mother cells in pollen sacs of anthers. Thus, palynology alynology is the science of pollen and spore morphology and its applications. It is derived from the Greek word ‘palynein’ meaning ‘to scatter’. Morphological and comparative studies in palynology may solve intricate taxonomic problems. Pollen characters are useful in solving several complicated problems of interrelationships between various taxa and assessment of their status in the classification (Zhigila et al., 2018). Pollen grains are in the binucleate stage at the time of pollination.
Wodehouse (1935) and Erdtman (1943, 1952, 1954, 1963 & 1969) made the most remarkable contribution in the field of pollen morphology. The significance of pollen attributes in taxonomy has been realized during the last three decade Erdtman (1952); Wagenitz (1976); Stix (1960), and Nair (1974). Dr. Parmeshwaran Krishnan Kutty Nair, fondly referred to as P. K. K. Nair (Fig. 8.1) and considered as the father of Indian palynology. Palynological renaissance, which started in 1952 with the contributions of Erdtman (1952) and Faegri and Iversen (1950), grew with the scientific activities of Nair and took a concrete shape in 1964 when he conveyed a symposium at NBRI, Lucknow.

This process involves building up a coating of sugar and sometimes of other things, layer by layer. Panning is one of those processes that the confectionery and pharmaceutical industries have in common.

The coating of confectionery with sugar using a pan is very ancient. Originally, these products were made in an open pan suspended over a fire by chains. Apparently the operator swung the pan by hand, coating the product with sugar syrup which was then allowed to crystallise. The normal modern small-scale method is to use a rotating dragee pan (Fig.No.19.1).

These are elliptical vessels made traditionally of copper, but now more commonly of stainless steel. The pan is equipped to be rotated and usually there is a system for supplying and extracting air and possibly with a system for spraying in the sugar syrup. Typical pan sizes are between 1.5 and 0.9 m in diameter although smaller sizes are used for small-scale work.

INTRODUCTION

The term ‘ginseng’ is applied to a range of plants from family Araliaceae involving genus Panax. Out of the many species available in nature, Himalayas are also home to a commercially lesser known variety called as Panax psuedoginseng Wall (Nayar and Shastry 1990). In the interior temperate areas of the eastern Himalayas, the species is distributed across Sikkim, Bhutan, Nepal, and extends into China. Keeping in view its high commercial international demand, CSIR-Institute of Himalayan Bioresource Technology (CSIR-IHBT) Palampur has recently taken an initiative to introduce and cultivate Chinese ginseng (Panax ginseng) in the Lahaul valley of Himachal Pradesh, in India. This chapter addresses the different biological, chemical, medicinal and cultivation aspects of both the indigenous Himalayan variety (P. psuedoginseng) and the introduced Chinese species (P. ginseng) in particular.

Introduction
Panch Parivartan, which translates to “Five Transformations,” is an innovative framework that uses information technology (IT) to catalyze a profound and holistic transformation across multiple sectors of society, governance, and the economy. This framework aims to create a sustainable and inclusive model for development by leveraging IT to drive change in key areas, including governance, economic growth, social equity, education, and environmental sustainability. In India’s development, particularly in the drive towards a Viksit Bharat (Developed
India) by 2047, the Panch Parivartan framework outlines a roadmap where IT is the backbone for achieving transformative change. Through the strategic deployment of IT solutions, the framework seeks to address complex challenges, unlock new opportunities, and pave the way for a more equitable, efficient, and sustainable society.

Panchayati Raj is the oldest system of local government in the Indian subcontinent. Panchayati Raj Institutions have been in existence in India for a long time. In the old Sanskrit scriptures, word 'Panchayatan' has been mentioned which means a group of five persons, including a spiritual man. In the Rigveda, there is a mention of Sabha, Samiti and Vidatha as local selfunits. These were the democratic bodies at the local level. The king used to get the approval of these bodies regarding certain functions and decisions.

After independence, as a development initiative, India had implemented the Community Development Programmes (CDP) on the eve of Gandhi Jayanti, the 2nd October, 1952.The National Extension Service followed the Community Development Programme as the vehicle through which idea of Community Development would be worked and to build up an administrative system which can tackle the welfare problems of growth at the local level. The Balvantray Mehta Study Team was appointed in January 1957 to study and to make report on the Community Development Projects and National Extension Service .The Team brought to focus the areas mentioned below:

India has experienced marked changes, both at international and national levels. Technological progress, ICT penetration in rural and urban areas, and changes in current government policies have resulted in changes in the country’s social structure and power relations. The government initiated various programmes like Rashtriya Mahila Kosh (RMK), Development of Women and Children in Rural Areas (DWCRA), Mahila e-Haat, and Support to Training & Employment Programme (STEP) etc. are there to improve the state of rural women. 

Evolution of Panchayati Raj System in India

In January 1957, the Government of India appointed a committee under the chairmanship of Balwantray Mehta to examine the working of the Community Development Programme (1952) and the National Extension Service (1953), and to suggest measures for their better implementation. The committee expressed concern about the lack of participation of people in these programmes and made a string plea for devolution of power. The committee submitted its report in November 1957 and recommended the establishment of the scheme of ‘democratic decentralization’ through a three-tier system of local government from village to district Level-Gram Panchayat at village level, Panchayat Samiti at block level and Zilla Parisad at district level -which ultimately came to be known as Panchayati Raj in India. The recommendations of the committee were accepted by the National Development Council (NDC) in January 1958. The NDC did not insist on a single rigid pattern of panchayat raj system throughout the country but left it to the states to evolve their own patterns suitable to local conditions. But the basic principles and broad fundamentals of democratic decentralization remained identical throughout the country. Thus, the Panchayati Raj system came into existence in 1959 with two basic objectives. These were (1) democratic decentralization and (2) local participation in planned programmes. The new system of Panchayat Raj Institutions was first adopted in Rajasthan and Andhra Pradesh in 1959, followed by Assam, Tamil Nadu and Karnataka in 1960, Maharashtra in 1962, and Gujarat and West Bengal in 1963 and 1964 respectively. By the mid-sixties, the hype to strengthen the Panchayati Raj Institutions (PRIs) gave way to a growing tendency of centralization and the PRIs descended to ground zero. To revive the working of PRIs, the Janata Government in 1977 appointed a committee headed by Ashok Mehta to study the functioning of PRIs and to suggest measures for improvement. The committee suggested a minor change in the Balwantray Mehta Scheme. Mehta (1978), in the Report of the Committee of Panchayati Raj Institutions (PRIs) identified three phases of Panchayati Raj in India

11.1 Introduction

Pandas is an open-source Python Library providing high-performance data manipulation and analysis tool using its powerful data structures. The name Pandas is derived from the word Panel Data - an Econometrics from Multidimensional data.

In 2008, developer Wes McKinney started developing pandas when in need of high performance, flexible tool for analysis of data.

Prior to Pandas, Python was majorly used for data munging and preparation. It had very little contribution towards data analysis. Pandas solved this problem. Using Pandas, we can accomplish five typical steps in the processing and analysis of data, regardless of the origin of data - load, prepare, manipulate, model, and analyze.

Python with Pandas is used in a wide range of fields including academic and commercial domains including finance, economics, Statistics, analytics, etc.

Pandemic : An epidemic occurring over a very wide area (several countries or continents) and usually affecting a large proportion of the population.

Partial Evaluation : Partial evaluations constitute a number of economic study types which consider costs and/or consequences, but which either do not involve a comparison between alternative interventions or do not relate costs to benefits.

Participation bias : People who participate in a study, especially volunteers, may be systematically different from those who do not, in a way that can affect the response to a treatment. For example, if volunteers are chosen to test the effects of a vaccine, one might find a lower incidence of disease in this population simply because they are more health conscious than those who would not volunteer for such a study.

Path dependence : History matters. Where you have been in the past determines where you are now and where you can go in future. Indeed, even small, apparently trivial, differences in the path you have taken can have huge consequences for where you are and can go. In economics, path dependence refers to the way in which apparently insignificant events and choices can have huge consequences for the development of a market or an economy.

Pansy belongs to the family Violaceae, genus Viola and species tricolor. Pansy also known as butterfly flower, cat face. Pansies are annuals or short-lived perennials, grow 15-30 cm tall and have heart-shaped leaves at the base and oblong leaves growing from the stems. The pansy is quite durable and a “flower for all seasons”. The fragrant and edible blooms are desirable in gardens. Pansy popularity increases possible due to its ease of growing. Whether grown from seed or bedding plants, pansies are relatively disease and pest free blooming prolifically for the gardener’s enjoyment.

Whether grown from seed or bedding plants, pansies are relatively disease and pest free blooming prolifically for the gardener’s enjoyment. The pansy is a group of hybrid plants cultivated as garden flowers. Pansies are derived from Viola species Viola tricolor hybridized with other Viola species, these hybrids are referred to as Viola × wittrockiana or less commonly Viola tricolor hortensis. The pansy is used in phytotherapy. The pansy is the symbol of Free thought. For Viola species, there is strong resistance to cold, flowering early and long flowering period. Also be used to cover a large area on the ground flower beds, its colour range, forming a unique landscape in early spring, but also in the flower bed with the string of red, petunia colour, or for potted plants and planted tank, decorative balconies, bay windows and stairs.

ORIGIN AND DISTRIBUTION

The modern pansy, Viola x wittrockiana, is thought to have derived from Viola tricolor, a native of central Europe. The center of origin for Viola was continental Europe. Viola is widely distributed in temperate areas in the northern hemisphere and in S. America, with centres of diversity in S.E. Europe, E. Asia and S. America; isolated endemics occur in Africa (equatorial high mountains and the Cape), E. Australia, Tasmania, New Zealand and Hawaii. V. sororia as defined by McKinney (1992), is widely found across the United States and Canada. Each subspecies has a smaller distribution. V. sororia var. sororia is found in the mid to eastern United States and southern Canada, V. sororia var. affinis, is found in western and extreme northeastern sections of the United States and Canada, V. sororia var. missouriensis is found in the eastern United States, and V. sororia var. novae-angliae is found in Minnesota, Wisconsin, Maine, Quebec and New Brunswick. Of the four varieties only V. sororia var. sororia and V. sororia var. missouriensis are native to New Jersey (McKinney, 1992). V. sororia var. sororia is found in drier areas than the other four subspecies and often in waste grounds (McKinney, 1992) or on the forest floors of open woods in semi-shaded conditions (McKinney, 1992).
