Abstract

Mythology is a unique subject of religious or cultural traditions. Plants play a vital role in the practice of these traditions. The use of plants may be an approach towards their conservation by demonstrating their magico-religious importance or their efficiency in keeping away some infectious microbes. Reason may be any, but all such herbs needs scientific interventions with respect to their usage. In this manuscript 69 such plant species are enumerated which are used for magico-religious purposes. Maximum species were recorded from dicots and seeds have shown maximum percentage among the plant parts to be used for the purpose. The knowledge about the magico-religious usage among the inhabitants is communicated through oral, literature or practice. The quantitative indices like Cultural Significance Index and Factor Informant Consensus have been calculated for the collected data from 92 informants in the region. The calculated ethnobotanical quantitative indices indicate Capsicum annuum and Santalum album are the culturally more significant plants and there is a strong homogeneity in the practices among the people of different districts.

Introduction The botanical name of carrot is Raphanus sativus which belongs to the family Brassicaceae having haploid chromosome number of x = 9 and is believed to be originated from Europe and Asia. Radish is one of the most ancient and popular leaf cum root vegetables in both tropical and temperate regions. Radish probably originated in Europe and Asia. Radishes were extensively cultivated in Egypt and ancient records show that radishes were eaten before the pyramids were built. It had spread to China during 500 BC and to Japan during AD 700. The recent study has indicated that east of Mediterranean region, most probably China is the centre of origin of radish. Wild state of radish is not known. Previously it was believed to haveevolved from a common weed Raphanus raphanistrum Linn in Europe but now it is believed to have been evolved from more a variety of sources. As it is a short duration annual or biennial crop, it can be widely used in sequence cropping, companion cropping and intercropping in widely spaced crops. Roots are pink in colour due to presence of anthocyanin pigment.

Lipids are non polar substances of biological origin that are sparingly soluble in water, but soluble in organic solvents like chloroform, hexane, benzene etc. The word lipid comes from the Greek word lipos meaning lard or fat. The lipids present in biological systems are either hydrophobic (non polar) or amphipathic (both polar and non polar). Lipids like fats, oils or glycerophospholipids can be hydrolyzed to get fatty acids and other products. Hydrophobic nature is useful in making lipids as membranes which act as effective barriers to more polar molecules. Steroids are also considered lipids, but cannot be hydrolysed and are components of non-saponifiables in fats. Waxes, which are esters of fatty acids with long chain alcohols are also considered as lipids.

This chapter begins with an introductory overview, providing a basic understanding of correlation and its types. It guides readers through in-depth analysis using R, demonstrating how to apply these concepts practically.

Correlation

Correlation analysis is a statistical method used to evaluate the strength and direction of the relationship between two variables. This analysis is vital in identifying and understanding how variables are interconnected within a dataset, providing insights into their mutual influences.

Key aspects of correlation include

• Range of the correlation coefficientThe value of the correlation coefficient (“r”) falls within the range of −1 to +1.

• Independence from origin and scaleThe correlation coefficient (“r”) remains consistent regardless of any changes in the origin or scale of the variables.

• Unit independenceThe correlation coefficient is independent of the units of measurement

of the variables.

• Relationship with independenceWhile uncorrelated variables are generally independent, the reverse is not necessarily true; independent variables will always be uncorrelated.

Current status of researches on VA mycorrhiza and their benefits to the plants carried out by the mycorrhizasts of the country has been described in detail in chapters II to X.

Prior to the establishment of any specific forum, the pace of research on VA mycorrhiza in the country was not of desired level. However, the activities related to research on VA mycorrhiza gained unexpected momemtum when Mycorrhiza network came into exixtence in the year 1989. The network provided not only assistance and guidance of various types to the scientists working on VA mycorrhiza in the country but also offered them periodical platforms to exchange their informations and thoughts on status of researches on VA mycorrhiza and to propose future strategies of research. During the National conferences held in different parts of the country the panel of experts made certain observations regarding future prospects and strategies for research on VA mycorrhiza. They have been mentioned in the present chapter.

1. AN OVERVIEW OF RWANDA’S SOCIO-ECONOMIC SETTING

Rwanda is a small landlocked country located in East Africa covering a total surface area of 26,338 km². It lies about 120 km south of the Equator and is bordered by Uganda in the North, Tanzania in the east, Burundi in the south and the Democratic Republic of Congo in the West. According to the national official statistics, the total population is approximately 8,200,000 people, with women accounting for 55 per cent of the people. The country’s population density is 505 people per km², making it one of the most densely populated countries in Africa (National Institute of Statistics, 2002). Since the turn of the millennium, the annual growth rate of the population has been 2.9 per cent and it is believed that by the year 2020, the country will have an estimated population of 20 million, thus exerting pressure on the limited land resources. It is also important to note that most people (64 per cent), those living in abject poverty, reside in rural areas of the country (Government of Rwanda, 2008).

ABSTRACT

Traditional herbal drug preparations are known for centuries to protect several human diseases such as peptic ulcer, diarrhea, piles and dysentery. Current days knowledge about the underlying biochemical mechanism for most of the gastric ulcers and majority of the duodenal ulcers deserve appropriate consideration and due weightage while consolidating regarding the efficacy of a plant extract. The present investgation relates to a pharmaceutical composition comprising an effective amount of lyophilized extract or at least one bioactive fraction obtained from flowers of Woodfordia fruticosa (L.) Kurz, along with one or more pharmaceutically acceptable additives or carriers. The present results provides a composition for treating ulcers such as stress induced ulcer, peptic ulcer, cold restraint induced ulcer, drug induced ulcer and acid induced ulcer, and also the composition used as specific inhibitor of gastric H+, K+-ATPase. Herbal formulation in the form of capsules were conducted on marker-based stability studies as per ICH Q1 guidelines at accelerated and real time stability studies (40±2°C, 75% ± 5% RH and 30±2°C, 65%±5% RH, respectively), and also stability testing investigation was done as per stability specifications at intervals of 0, 3, 6 months for accelerated stability studies and 0, 3, 6, 9, 12, 18, 24, 36 months for real time stability. The present data reveals that this species is one of the potent Indian medicinal Plant which helps in curing ulcer and associated diseases.

ABSTRACT

Donor-recipient protoplast fusion vis-à-vis cybridization is an effective technique to transfer plasmon-coded traits in cultivated tetraploid (2n=4x=48) potato (Solanum tuberosum L.) from its diploid (2n=2x=24) cross-incompatible wild relatives. However, the method, although attractive, is difficult in terms of not only inactivation of nuclear and plasmonic genomes of the participating donor and recipient protoplasts, but also post- fusion culture and regeneration of putative cybrids. Here, we report an improved method for donor-recipient protoplast fusion and subsequent post-fusion culture and regeneration of electrofused protoplasts in potato. In the present experiment, Solanum verrucosum Schlechtd. (2n=2x=24) accessions CPC 1339 (CGN No. 17774) and HAW 2246 (CGN No. 17766) containing sensitive [Tr^s] plasmon for tetrad-type cytoplasmic male sterility were used as donors and S. tuberosum subsp. tuberosum cvs Kufri Ashoka, Kufri Chipsona-1 and Professor Broekema as recipients. For nuclear inactivation, the in vitro-cultured donor plants were exposed to 1000 Gy of unfiltered γ-rays before protoplast preparation using a revised protoplast isolation medium (PIM) containing 2.0 % Cellulase ‘Onozuka’ RS and 0.25 % Macerozyme R-10. The recipient protoplasts were treated with antimetabolite iodoacetate (1.0 mM ) for 45 min at 10 °C for chondriome inactivation. The protoplasts were aligned in an amplitude of 300 Vcm^-1 for 0.5-1.0 s before being electrofused by one DC pulse of 600-800 Vcm^-1 for 40 μs using a Cell Electrofusion Processor FPH 01001 (Bioelectronics Corporation, Troy, Michigan). The fused protoplasts were immobilized in alginate-plates, and cultured on modified VKM medium containing 0.3 M glucose at about 400 mOsmol (pH 5.6). After 8-10 weeks, the developing protocalluses were dissociated from alginate-plates and cultured for regeneration on MS medium supplemented with varying concentrations of zeatin/ zeatin riboside and gibberellic acid. The protocalluses derived from electrofusion between donor S. verrucosum accession CPC 1339 and recipient S. tuberosum cv. Kufri Chipsona-1 could be successfully regenerated into plantlets. Morphological as well as molecular-genetic characterization of regenerated microplants, both for nuclear and chondriome genomes, confirmed the putative cybridity as well as established the extent and pattern of mitochondrial recombination following donor-recipient protoplast fusion. The results have been discussed in relation to donor-recipient protoplast fusion approach and its potential application in potato genetic improvement.

Biological control is a strategy which employs utilization of natural enemies to reduce the damage caused by noxious organisms to tolerable levels (De Bach and Rosen, 1991). This is the most benign method for reducing pest population in vegetable ecosystem. It opens an amicable platform for production of organic vegetables with good export value. Since the late 1950s, much of the insect control in vegetables has been based on the use of synthetic chemical insecticides. Insecticides are relatively easy to use and have generally provided effective pest control. It is likely that they will always be a component of pest management programs. But, insecticides have some undesirable attributes. They usually present some degree of hazard to the applicator and other people who may come in contact with them, they can leave residues that some find unacceptable; they can contaminate soil and water and affect wildlife, aquatic life and other non-target organisms, they can interfere with beneficial organisms, such as pollinating insects and the natural enemies of pests. The insects also can develop resistance to insecticide. For these reasons, there is growing interest among farmers, entomologists and gardeners to explore and adopt methods that reduce pesticide use. 

INTRODUCTION
Transmission is a mechanism designed to reduce speed, consisting of multiple gears. It functions as a series of gears and shafts that transmit engine power to the tractor wheels. This system includes various components that enable both forward and reverse movement of the tractor, adapting to different field conditions. The entire route through which power flows from the engine to the wheels is referred to as the power train.
FUNCTIONS OF THE POWER TRANSMISSION SYSTEM
1. To transfer power from the engine to the tractor’s rear wheels.
2. To provide reduced speeds to the rear wheels as required.
3. To adjust the ratio between wheel speed and engine speed to match varying field conditions.
4. To facilitate power transmission through a right-angle drive, as the crankshaft and rear axle are typically positioned at right angles to each other.
The power transmission system is composed of several components: clutch, transmission gears, differential, final drive, rear axle, and rear wheels. Together, these components ensure the effective transmission of power.

Drumstick or Moringa is one of the world’s most useful crops and  is a tropical tree with multiple uses and its main feature is that it  is hardy with tremendous capacity to withstand drought. It is indigenous to the sub-Himalayan track extending from river Chenab to Sharda. It is grown  in  arid to humid areas of the tropical region  as a  human food crop mainly as a vegetable, animal forage crop, medicine, dye and oil yielding crop and for water purification. Among the 13 species known in the family Moringaceae, Moringa oleifera Lam is particularly easy to reproduce and its growth is very fast. The species is characterized by its long, drum stick shaped pods which contain  seeds. Within this species, utilizing its fast growing nature  and bearing fruits or pods selections are made to release varieties which can be grown as annual crop.During the very first year of growth, moringa  grows up to 4 meters and  bears fruit within the same first year (Folkard and Sutherland, 1996). The plant sheds its leaves with  onset of winter, stops producing flowers and virtually fruit set will not be there.

The numerous economic uses of Moringa oleifera together with its easy propagation have raised growing international interest for this tree which originated from India and  found in most tropical countries (Africa, Asia and America). Presently its cultivation on large scale  is seen in  India, Israel, Thailand, South Asian Countries, Africa and Pacific Islands. Presently in India, it occupies an  area of about 40,000 ha with  major growing areas in  Andhra Pradesh, Karnataka and Tamil Nadu which account for  more than 80 % of the area and production in India.

Abstract

Toxic plants are a grave threat to existence and bodily functions of humans and animals resulting in death or sickness through accident, unawareness or bad intention resulting in huge economic loss. They have always been part of our daily life and some of them are so prevalent that we do not even doubt their poisonous nature. The study aimed at systematically documenting the precious traditional knowledge regarding the ethnotoxic plants of district Udhampur. Ethnotoxic data was collected by interviewing 125 infomants between the age group 24-95 years. A total of 89 plant species belonging to 69 genera and 43 families were observed to be toxic to either humans or animals or both. Majority of the taxa were growing in wild. Leaves were observed to be the most toxic plant parts. Frequently encountered toxic plant families include Fabaceae, Solanaceae, Asteraceae, Euphorbiaceae, Apocynaceae and Ranunculaceae. The route /mode of entry of toxic chemicals was mainly observed to be ingestion. A total of 62 ailments/ conditions/diseases were reported to be caused in humans or animals or both by the ingestion, contact or inhalation of toxic plants in the present study. These include nausea, vomiting, headache, diarrhoea, hematochezia, abdominal spasms, anorexia, dysuria, deep yellow or no urine, bloat, etc. The present study may serve as a base line data for further research and will go a long way in safeguarding people from being poisoned by stuff that may have healed them.

1. Introduction

There is a global evidence of deterioration of nutrition and food security condition following the Pandemic and subsequent economiclockdown (Summerton, 2020; Laborde et al., 2020). In India, the status of nutrition and food security has been a matter of concern for decades. India scored an alarming rankof 102 out of 116 countries in Global Hunger Index (IFPRI, 2019). The problem has also been a gendered one, with an abysmally higher proportion of malnourishment and hunger in women and children in India. As per NFHS 4 (2015-16), every second woman in reproductive age in India was suffering from anaemia, two in five children were suffering from stunting and every tenth child in India was suffering from acute malnourishment (IIPS, 2017). It is not difficult to imagine that this existing malnutrition-crisis has only worsened in the post-lockdown period. There is a consensus among academicians, policy makers and planners that the nutrition crisis needs to be linked to gender-based exclusions & vulnerabilities (Quisumbing et al., 2020). This chapter attempts to discuss some of these complicacies of food-nutrition-gender linkages to put forth gender advocacy for food & nutrition policies.

Evidence of linkages between gender and nutrition are there althoughit is difficult to establish precise empirical connect. Also, the pathways through which gender influences nutrition and food security are multiple and complex. Food/nutrition-policy, therefore, has a long way to go till it is gender-informed. To begin with, the understanding of the concept of gender is limited at the policy-level. Moreover, most of the nutrition-food related policies in India have not mainstreamed gender or are working ina gender-specific manner rather than redistributive manner¹.

It is in this pretext the chapter reviewed the available evidence on gender-nutrition linkages to put forth an argument not only in favour of gender-aware nutrition policies, but also to guide as to how Gender should be integrated. The chapter is structured in five sections with sections that discusses the concept, i.e., importance of context in policy-level for conceptualising gender-needs. This is followed by a review of existing work from a Gender Needs framework and selected empirical evidence from recent primary study of the author are also presented as another separate section. The relevance of reviewing gender-nutrition linkage after COVID19 Pandemic also find place in the chapter. Finally the summary concludes the discussion on gender advocacy in nutrition.

Virus can be defined as a genetic element containing either DNA or RNA that replicates in host cells as intracellular parasites but is characterized by having an extracellular state.

Virus can use the metabolic machinery of the host cell and can modify the genetics of the host cell. Virus has both extracellular and intracellular state.

Extracellular State

Outside the host cell, the virus is a minute particle containing nucleic acid surrounded by protein, which is referred as virions or virus particles. Virions are inert and have no biosynthetic and metabolic functions. Extracellular state or virus particle is the perfect stage of virus to study the morphology and chemistry.

Intracellular State

The active state in which the virus replicate in the host cell. When the virus nucleic acid is introduced to host cell and replication starts, the process is referred as infection. The cell in which infection of virus and replication takes place is referred as host cell.

Abstract

Herbal healthcare forms the most favored system for curing various ailments of the people residing in remote areas of Himalayan region. Gujjar and Bakerwal tribes inhabit the hilly areas of Pir Panjal region of J&K along with their livestock and rely on the surrounding bio-wealth for their healthcare needs. But, proper documentation of traditional knowledge about the medicinal plants has been poorly attempted in this part of J&K. In order to develop a data base of plants being used by Gujjar and Bakerwal tribes of district Poonch, present attempt has been made. The present compilation recorded one hundred forty five plant species belonging to 133 genera and 76 families which are used by the tribal people to cure various ailments like rheumatism, diarrhea, dysentery, skin and gastric problems, wound healing etc. These medicinal plants comprise of 25 trees, 27 shrubs, 82 herbs and 11 climbers. Of the total, 44 species are native to Himalayan region and 101 are non native.

Advantages of Quantitative Research

Bovine milk contains an average of 3.5% protein. The concentration of protein changes significantly during lactation. The first few days of lactation exhibit the main change in protein concentration. The main changes occur in whey protein fraction.

Distribution of Protein in Milk

80% casein and 20% whey protein (β lactoglobulin- 10%, α- lactalbumin- 5%, serum albumin, and immunoglobulin- 5%).

Fractionation of Milk Proteins Fractionation of milk protein is mainly done by acidification at pH 4.6 around 30 °C.

Almost 80% of the bovine milk protein precipitates at pH4.6, and this fraction yielded by precipitation is called casein.

The remaining soluble part of the protein is referred to as whey protein/serum protein/ non- casein protein. Wide variation is observed in the casein- whey protein ratio in different types of milk(protein synthesis is independent of animal diet)

Significant Difference Between Casein and Whey Protein

1. Casein precipitates at pH 4.6 but does not precipitate whey protein at that pH. This property of milk protein is commercially exploited for the preparation of industrial casein and certain varieties of cheese.

2. Chymosin or other proteolytic enzymes produce specific changes in casein resulting in coagulation in the presence of calcium. Whey protein does not undergo this type of coagulation.

3. Casein is very stable to high temperatures. They can withstand heating up to 140 °C for 20 minutes but whey protein is relatively heat labile. They are completely denatured by heating at 90 °C for 10 min.

4. Casein is a phosphoprotein containing an average of 0.85% phosphorous while whey protein does not contain any phosphorous. The phosphate of casein is an important contributor to remarkably high heat stability and calcium- induced coagulation of rennet- altered casein.

5. Casein contains very low sulfur (0.8%) whereas whey protein is relatively rich in sulfur (1%). The principle casein contains only methionine but whey protein contains a significant amount of cystine, cysteine, and methionine. These sulfur- containing amino acids are responsible for many changes in milk on heating.

6. Casein is synthesized only in the mammary gland and no other sources in nature. Some of the whey proteins β lactoglobulin, and α- lactalbumin are synthesized in the mammary gland but bovine serum albumin and immunoglobulin are not synthesized in the mammary gland but derived from blood.

7. The whey protein is dispersed in solution and has a simple quaternary structure. Casein has a complex quaternary structure and exists in milk as large colloidal aggregates.

5.1 Introduction
A common method for combining metals in a wide range of applications is welding. Welding takes place in a variety of places, including factories and workshops, as well as outside on rural farms and construction sites. Basic welding techniques can be easily learnt, and the processes involved are quite straightforward to understand. The molecular joining of metals is called welding. When two or more pieces of metal are joined together uniformly such that the joint’s strength is greater than the combined strength of the individual components is known as a weld.
5.1.1 Key Terminologies of Welding
Four materials and other two elements are needed for welding, which are as listed below.
i. Metals
ii. Heat source/ flame
iii. Filler/ flux material
iv. Electrode
v. Air shield
vi. Coatings
To create a single piece of metal, the metals are heated to their melting point while being kept out of the air. A filler metal is then added to the heated area. It can be done under pressure or without pressure. In some cases, filler material need not be used. Air is used as a shield to cover the welding zone from oxidation.
5.1.1.1 Metals
Metals are the workpieces, which are to be joined. These metals may be similar or dissimilar. There are many situations wherein two or more workpieces are to be joined. Consider internal combustion engine in which valve timing gears are fixed over cam shaft. The fixing of the cam over the cam shaft is carried out by welding. Here, the workpieces are the cam and the cam shaft
