The use of sampling in making decisions about an aggregate (or population) is possibly as old as civilization itself. Sampling is first broadly classified into two categories known as subjective and objective. Any type of sampling which depends upon the personal judgement or discretion of the sampler himself, is called subjective sampling. But the sampling method which is governed by a sampling rule or is independent of the sampler’s own judgement is known as objective sampling. The main difficulty with subjective sampling is that the sampler is ignorant of the degree of representativeness of his sample or the accuracy of the final estimates of the population values obtained.

Objective sampling is further subdivided as non-probabilistic, probabilistic and mixed. In non-probabilistic objective sampling, there is a fixed sampling rule but there is no selection probability attached to the sampling unit e.g. selection of every 10th individual from a list, starting with the first, or selecting every 10th line in a paddy field. If however, the selection of the first individual is made in such a manner that each of the first 10 gets an equal chance of being selected, it becomes a case of mixed sampling, partly probabilistic and partly non-probabilistic). On the other hand, if for each individual unit there is a definite pre-assigned probability of being selected, the sampling is said to be probabilistic sampling.

Abstract

Powdery mildew infected leaves of apple hyperparasitized by Ampelomyces quisqualis were collected from field and examined for the presence of the dark brown pycnidia of  hyperparasite. The hyperparasite was isolated on potato dextrose agar medium by standard isolation technique. The morphological characters of the hyperparasite such as size and shape of pycnidia and pycnidiospores were studied. Six systemic fungicides were evaluated for their compatibility with A. quisqualis under in vitro conditions. Dinocap was least inhibitory giving 65.56 per cent growth inhibition of A. quisqualis followed by mancozeb (66.67%). Effect of these fungicides was also seen on conidial germination and germ tube length of A. quisqualis. Maximum conidial germination and germ tube length was observed in mancozeb followed by benomyl and dinocap.

Abstract

A promising strain/seedling have been identified that produces only male flowers (small and pink tinged) on the ventral side of the current season’s shoot all along its length. As many as 24 flowers per shoot were observed. The seedling continued to flower for about one month which attracts large number of honey bees. The pollen is also produced in abundance that dehisces early in the morning. Preliminary observations on the flowering behaviour and pollen studies have revealed that it can be used as a suitable polliniser for persimmon cultivars in general and Hachiya cultivar in particular.

1. Introduction

Phytochemicals are compounds present in fruits that are not required for normal functioning of the body, but have a beneficial effect on health or play an active role in amelioration of diseases. Phytonutrients have various health benefits like antimicrobial, anti-inflammatory, cancer preventive, antidiabetic and antihypertensive. The pigments of the fruits have many therapeutic benefits including vasoprotective and anti-inflammatory properties, antiproliferative, chemo protective and anti-neoplastic properties, reversing age related deficits (Joseph et al.,1999) and useful in controlling oxidative stress during pregnancies complicated by intrauterine growth retardation (Pawlowicz et al.,2000). Cocculus hirsutus Linn. is a climber and widely distributed in tropical and subtropical climates. This plant is commonly called as kattu kodi in Tamil. It belongs to the family Menispermaceae. The fruit is a drupe which is size of small pea with red purple endocarp (Fig.1a and Fig.1b). The plant is used in treatment of gonorrhea, spermatonorrhea, Urinary troubles, diarrhea and hyperglycemia (Kirtikar and Basu, 2002). The leaves of the plant have been evaluated for anti hyperglycemic (Badole et al., 2006); antibacterial (Panda et al., 2007); diuretic and laxative (Ganapaty et al., 2002). Several isoquinoline alkaloids are present in leaves and roots; the important ones cohirsine, cohirsinine, cohirsitinine, hirsutine and jamtine (Viqaruddin et al., 1987; 1991; 1992; 1993). Since no detail scientific approach has been made to study phytochemicals of cocculus hirsutus fruit. So in the present investigation preliminary

Abstract

Ten GPS stations have been set up in campaign mode in North Bengal in the Himalayan foothills and frontal zone, of which 7 have been reoccupied. Data from these 7 GPS stations over the period December, 2005 – January, 2007 have been processed using GAMIT/GLOBK suite of software and the velocities of these stations have been estimated. Since the data obtained so far cover a span of one year only, the conclusions derived from them are to be considered as preliminary. The stations are found to be moving at the rate of ~ 40-55 mm/yr in ITRF05 reference frame towards NNE. The baseline between LHAS (Lhasa) and IISC (Bangalore) is estimated to be shortened by ~10.2 mm over the period of our measurement. The southernmost station in our study, NBUV, at Siliguri is more or less collinear with LHAS-IISC baseline. The shortening of NBUV-IISC line is estimated to be ~ 3.8 mm over this period and that of NBUV-LHAS line is ~ 6.4 mm for the same period. These GPS stations were set up across the parallel set of previously marked fault scarps named Matiali (MT), Chalsa (CL) and Baradighi (BD) faults in North Bengal between longitudes 88⁰ E and 89⁰ E. The results from the GPS measurements show that stations to the south of the BD fault are moving at a faster rate than those to the north of MT fault. The baseline between stations AMBK (Ambiok) and NBUV has shortened by ~3 mm over the period of our observation. These two are the northernmost and southernmost stations respectively with respect to the three E-W running parallel faults and thus the shortening of baseline AMBK-NBUV is due to movements on the set of three faults taken together. A N-S to NNE-SSW running line of discontinuity between 88.5⁰ E and 89⁰ E longitudes separates the velocity vectors of the set of stations SAMS, JITI, PMSM, BRDH to the east of the line and the set of stations NBUV, BGKT, AMBK to the west. The line of demarcation of the two blocks containing the two sets of stations appears to coincide with the Gish transverse zone (GTZ).

Plant Growth Regulator (PGR) are diverse group of organic compound other than nutrients, produced artificially or by plants which in low concentrations promote, inhibit or modify the physiological process in plant. Among the PGRs produced by plants are auxins (indole-3-acetic acid and its derivatives), gibberellins, cytokinins, abscisic acid and ethylene.

Application of certain plant growth regulators promotes the process of seed germination, and development of roots in cuttings and layers. Various growth regulators have been used with striking success. Of these auxins such as indole3-acetic acid (IAA), indolebutyric acid (IBA) and naphthalene acetic acid (NAA) have the greatest effect on root formation in cuttings and layers. These chemicals speed up the healing of the wound, induce more roots and their development. They are now used universally in the propagation of many fruit plants. The growth regulators are effective in minute concentration and are usually applied in dilute solutions and dust formulations or rarely in grease bases such as lanolin. Plant growth regulators are generally calculated in the form of parts per million (ppm) or microgram per gram (mg/g).

Introduction

The nurseryman needs some records if he is going to plan for remunerative returns and establish himself as a reputable business. Ideally, a nursery planner should be able to estimate how long it takes to lift saplings or how much seed is required, or how many cuttings he can accommodate in a glasshouse, as well as how much scion wood is required for grafting a particular plot. In nurseries, specific registers must be maintained to keep track of day-to-day activities, such as pedigrees and operations. In case of large nurseries, these records are required by law to satisfy inspection authorities, calculate taxes, detect theft, or discourage it.

Regardless of the subject or content, having a lesson plan prepares teachers for class by providing detailed guidelines for the session. A lesson plan need not be lengthy or complex; it should simply outline what is being taught, the method of presentation, and the objectives and goals for student achievement.

Why Lesson Plans Are Important

• Preparation and Effectiveness: Preparing lessons in advance is crucial for implementing effective teaching strategies. Without a lesson plan, classes can become unproductive or confusing for both students and teachers. Proper preparation ensures that lessons are structured and focused.

• Classroom Management: Lesson planning is vital for classroom management. Developing a lesson plan based on learning objectives allows for flexibility in teaching methods and classroom management techniques. Different delivery approaches are needed for hybrid or online classes compared to traditional classes, and a well-prepared plan helps maintain focus and effectiveness regardless of the learning environment.

• Student Success: Well-structured lessons significantly benefit students, who are more likely to engage and show interest in the material. Lesson plans, guided by curriculum objectives, help teachers create valuable educational experiences, thereby increasing the likelihood of student success.

Cordial is a sparkling, clear, sweetened fruit juice beverage from which pulp/ fibrous material has been removed completely. It contains at least 25% fruit juice, 30% total soluble solids (TSS), 1.5% acid and 350 ppm sulphur dioxide. Lemon and lime are the most suitable fruits for making cordial.
Recipe: The recipe for the preparation of cordial as a general guideline is as under:
Extract the juice from lime or lemon as in squash and store in glass bottles after adding potassium metabisulphite @ 1.0 g/kg of the juice. Allow the juice to settle for a month. Decant the clear juice without disturbing sediments and strain it through a fine muslin cloth. Prepare syrup by mixing sugar with water, boil, strain and allow to cool. On cooling, mix juice in syrup and strain the cordial through muslin cloth if necessary. Add KMS and fill into bottles. Stor in a cool and dry place.

Jam: Jam is a product made by boiling fruit pulp with sufficient sugar to a reasonably thick consistency. Jam is mainly prepared by apple, pear, sapota, apricot, peach, papaya, karonda etc. It can be prepared from one kind of fruits or from two or more kind of fruits. In general jam contains 0.5-0.6% acid and invert sugar should not be more than 40%.

Fruit nectar is a type of fruit beverage that contains not less than 20% fruit juice or pulp, not less than 15o B total soluble solids and acidity ranging between
0.3-0.5 % but not exceeding 1.5%/. For orange and pineapple nectar, the fruit juice shall not be less than 40%. The product is preserved by heat processing/ thermal processing, as such no chemical preservative is permitted in nectars. Unlike squashes, fruit nectar is served chilled as such without any dilution.
Mango, guava, pineapple, papaya, jamun etc., are the most suitable fruits for making nectar.
Recipe: As a general guideline, the following recipe is used for the preparation of fruit nectar:
Procedure
i. Select fully mature and ripe fruit and extract pulp as discussed under fruit pulp making but do not add any chemical preservative.

Fruit pulps are semi-finished products that are used for manufacturing finished value-added products like jam, ready-to-serve beverages, squash, appetizers etc. According to Food Laws, pulp refers to an unfermented but fermentable product, pulpy, turbid or clear, obtained by a mechanical process from sound ripe fruits/vegetables. These are preserved either by heat processing or by using chemical preservatives. The maximum preservative permitted under Indian Food Laws is 1000 ppm sulphur dioxide added in the form of potassium metabisulphite.
Mango, guava, apple, pineapple, papaya, bael, guava, peach, plum, apricot etc., are the most suitable fruits for making pulp for use in finished product preparation.
Procedure
i. Select fully mature and ripe fruit like mango, guava, apple, peach, apricot, kiwi, etc., and wash thoroughly.

Jam is prepared by boiling the fruit pulp with a sufficient quantity of sugar to a thick consistency, firm enough to hold fruit tissues in position. For the preparation of jam, not less than 45 parts of fruits are used for every 55 parts of sugar. The jam prepared by using two or more fruit pulps is called mixed fruit jam. Apple jam, apricot jam, mango jam, guava jam, pineapple jam, and mixed fruit jam prepared by using the pulp of two or more fruits are quite common. According to Food Safety & Standards Regulations,2011 the minimum TSS in the Jam shall not be less than 65%(w/w). Earlier the minimum limit was 68% (w/w)
Raw material, ingredients and utensils required
1. Fruits like mangoes, guava, apples, apricots, plum, peaches and kiwi etc singly or in combination
2. Stainless steel knives, de-corers, ladle, utensils for cooking and mixing, glass bottles (Jars), LPG or Diesel Bhatti, bucket/tub for washing, Stainless steel sieve, Steam Jacketted Kettle, Boiler (for the commercial unit) etc. 

Ready -to -Serve (RTS) drink is a type of fruit beverage that contains at least 10% fruit juice/pulp and 10o Brix total soluble solids with acidity ranging between 0.3-0.5%. The product is not diluted before serving like squash; hence it is called a ready-to-serve beverage. The product can be preserved by using 70 ppm SO2  or 120 ppm benzoic acid. Mango, orange, guava, lemon, lime, litchi, kiwi fruit, apricot, pineapple, etc., fruits are used for making RTS beverages. For lime & lemon drinks minimum level of juice content is 5% as per Indian Food Laws.
Recipe: As a general guideline, the following recipe is used for the preparation of ready-to-serve drinks:
Procedure
i. Select fully mature and ripe fruit like mango, guava, apricot, kiwi, etc., and wash thoroughly.
ii. Some fruits like mango, kiwi, pineapple, and litchi are peeled before heating. Apricots, guava, plums etc are not peeled. Place fruit after peeling in a pan/pressure cooker and boil till softening

Squash is a type of fruit beverage containing at least 25% fruit juice/pulp, not less than 40% total soluble solids (TSS), about 1-1.5% acid and not exceeding 350ppm sulphur dioxide or 600ppm sodium benzoate. Squash is diluted by adding cold/chilled water before serving (1:3).
Mango, orange, lemon, lime, litchi, guava, pineapple, jamun, plum, apricot, rhododendron petals etc., are used for making squash. Potassium metabisulphite (KMS) is generally used as a preservative, whereas sodium benzoate is used as a preservative in squash made from coloured fruits like plum, jamun, phalsa and rhododendron petals.
Recipe: A generalized recipe for the preparation of squashes from different
fruits as a general guideline is as under:

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

The procedure used in the preparation of samples depends on the purpose of analysis and the nature of the constituents that are to be determined.

a. Plant material (Herbage)

    1.    Separate the plant material by using sharp knife.
    2.    Remove the contaminations like soil or other material by gentle brushing. Never wash the plant material with water.
    3.    Mix corresponding plant parts from more than one plant to obtain representative sample of sufficient size for analysis.
    4.    Cut the sample immediately into small pieces and mix thoroughly. 
    5.    Weigh a portion of this sample for those analyses which are to be performed on green material. 
    6.    Dry the sample in a hot air oven at 100 ± 2ºC for storage.

Buffers

Bronsted and Lowry defined acids as substances which are able to donate protons, and bases as substances which accept protons.

In the above example, BH is an acid because it donates proton and B– is an anion liberated by the deprotonation of the acid. B– behaves like a base, so it is called conjugate base.

Acids can be classified into strong acids and weak acids.

1. Strong acids get dissociated almost completely, e.g., hydrochloric acid, sulphuric acid. This is because the conjugate bases of these acids are very weak (have less affinity for the proton).

2. Weak acids get dissociated partially, e.g., acetic acid, carbonic acid. This happens because the conjugate bases of these acids are strong (have greater affinity for proton). Since the dissociation of the weak acids is partial, the equilibrium constant for the dissociation reaction of the weak acid (BH) can be written as follows:

A. Circular letter
• Circular letter is a quick and cheap method of communication.
• It is a letter reproduced and sent to many people by the extension worker, to publicize an extension activity (like meeting, exhibits etc.) or to give information on farm and home problems.
• Circular letter could be used as a mail before organizing any campaign or extension work.
• It is sent from extension wing weekly or fortnightly to maintain regular contact with the farmers depending upon

Principle of construction of flash cards
• Flash cards are non-projected visual aid in which series of illustrated cards are flashed as presented in a proper sequence to explain complete story.
• The story must be familiar, with specific heading and suggestions at the last.
• Simple words and local expressions should be used in flash cards.
• Total number of flash cards must be 10 -12 which are easy to remember to farmers

Principle of construction of poster making
A poster is to be bold in design, simple to understand and attractive in colour. Poster is displayed in a public place with the purpose of creating awareness amongst the people. A poster is generally seen from a distance and the person glancing at to get first idea about it. Construction of poster making should be based on following components.
1. Pictures 2. Words 3. Space 4. Colors 5. Layout

a) Picture or illustration
1. Picture should be drawn in such a way that produce message clearly.

1. INTRODUCTION

Harvesting is the process of gathering the crops from the fields at maturity. The harvesting of a commodity means the end of the growing season for a particular crop. Harvesting is the most labour-intensive activity of the growing season. Harvesting in general includes an immediate post-harvest handling, the actions taken immediately after removing the crop are pre-cooling, sorting, cleaning, packaging and up to the point of on-farm processing or shipping to the wholesaler or consumer.

Harvest timing is a critical decision that balances the likely weather conditions with the degree of crop maturity. Weather conditions such as frost, rain and unseasonably warm or cold periods can affect yield and quality. These conditions can be avoided by harvesting the commodities earlier than the harvest date, but this may result in poor yield and quality. On the other hand, delayed harvesting also results in a better yield, but increases the risk of weather problems. Thus, proper harvesting timings of horticultural commodities often play an important role.

Assessment of harvesting time is a critical time for growers of fruit and vegetables to decide the accurate period of crop harvesting. Fresh produce is normally ready for harvest when it has developed to the ideal condition for consumption and the condition is usually referred to as harvest maturity. Harvest maturity thus refers to the time when the “fruit” is ready to harvest and the time required to reach market. The harvesting should be done earlier than its ideal maturity for proper marketing.

Most growers decide harvesting time for different commodities by looking and sampling. Judgments are based on colour, size and shape (Sight); texture, hardness or softness (Touch); odour/aroma (Smell); sweetness, sourness, bitterness (Taste) etc. Experience is the best guide for this kind of assessment. Harvest maturity can readily be observed in some fruit crops but it can be more difficult in case of some fruits like avocados remain unripe off the tree after maturity.

DNA fragment to be used as a probe should be purified by gel electrophoresis. The band can be located after staining with ethidium bromide and electroeluted.

The in vitro radioactive labeling of DNA fragment is accomplished by the incorporation of a radioactive nucleotide during strand synthesis with Klenow enzyme (large subunit of DNA polymerase-I).

Enterobacteria phage ? is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E.coli). It was discovered by Esther Lederberg in 1950. The wild type of this virus has a temperate life cycle that allows it to either reside within the genome of its host through lysogeny or enter into a lytic phase, during which it kills and lyses the cell to produce offspring. Lambda strains, mutated at specific sites, are unable to lysogenize cells; instead, they grow and enter the lytic cycle after superinfecting an already lysogenized cell.

Materials Required

Fruit juice/ pulp, cane sugar, potable water, essence, citric acid, colours, preservatives, weighing balance, bottling and sealing facilities, hand refractometer, homogenizer etc.  

Procedure

    1.    Extract the juice as discussed in previous exercise.
    2.    Filter the fresh or preserved juice through muslin cloth.
    3.    Calculate the quantities of juice, sugar, water, acid (if required), preservatives, colour, essence etc. required for preparation of a known quantity of                      squash as per FPO specifications.
    4.    Prepare the beverage as directed by instructor
    5.    Pack the beverage in bottles 
    6.    Seal the bottles and label them
    7.    Take out one of the bottles and measure its TSS and titratable acidity.

In the realm of cell culture, the quality and composition of the growth media and reagents play a pivotal role in growth and sustaining cells in vitro. The preparation of these essential components requires precision, attention to detail, and adherence to the strict protocols to ensure optimal cellular growth, viability, and experimental reproducibility. This introduction serves as a foundational overview of the critical aspects involved in the preparation of media and reagents for cell culture experiments. Furthermore, the preparation of media and reagents for cell culture necessitates adherence to stringent quality control measures to ensure consistency and reproducibility across experiments. Validation of media batches, sterility testing, and periodic quality assessments are essential practic

When we are having two or more than two feed ingredients and by using them we have to prepare a mixture of desired nutrient composition then we will require to use Pearson’s square method. Use of pearson’s square is a simple procedure that allows us to mix two feed stuffs with different nutrients concentrations and come up with a mixture of the desired total concentration. For the pearson’s square to work, the desired diet’ nutrient concentration must be between the nutrient concentrations of the two feed stuffs. Suppose we have a protein source such as ground nut cake (GNC) with 40.9% crude protein (CP) and maize with 8.8% CP, and we need a mixture of the two that will have 18% CP. AS shown in the illustration, we compare the CP percentage of each feed on the left with the desired percentage in the middle of the square. The lesser value is subtracted from the greater value and the answer, in parts of a mixture rather then in percentage, is recorded diagonally, but read horizontally.

Aim

To prepare a contour map by direct method using dumpy level.

Materials required

Dumpy level

Leveling staff

Measuring tape

Wooden pegs/chain pins

Field book

Theory

For locating a point on the ground on a contour, its position and elevation in a horizontal plane should be known. In direct method, the contours to be plotted are located on the ground with a level by making various points on each contour, and these points are surveyed and plotted on plan. This method is more accurate but slow and tedious, and is suitable for contouring small areas where great accuracy is required. For locating the points of the same elevation, the instrument is set in such a commanding position from where maximum number of points can be covered. The bench mark is established near the site of survey. The height of the instrument (H.I) is determined after taking a back sight (B.S) on the established bench mark.

A Detailed Project Report (DPR) is a vital document that outlines every aspect of a proposed project, serving as a strategic guide for all stakeholders involved. It typically covers project goals, timelines, budget estimates, resource planning, and risk evaluation. The preparation of a DPR usually begins after completing the initial planning and design stages and often follows a feasibility study to assess the project’s viability.
DETAILED PROJECT REPORT (DPR): MEANING AND IMPORTANCE
Essentially, the DPR serves as a final and elaborate blueprint of the project, laying out the specific resources, tasks, and methodologies required for successful execution. It clearly defines roles, responsibilities, and safety protocols to be followed during implementation.
Key factors determining project success include:
• Timely completion of the project
• Meeting client expectations through high-quality outcomes
• Staying within the approved budget despite cost escalations
The objective of a DPR is to translate a business investment idea into a practical, revenue-generating project. It presents a realistic and actionable plan for implementation, addressing potential risks and suggesting mitigation strategies. A well-crafted DPR ensures smooth execution and operational efficiency, making it a crucial document for project approval and success.
CONTENTS OF A DETAILED PROJECT REPORT
A Detailed Project Report (DPR) serves as a critical foundation for turning a project concept into a functional and successful venture. It should include the following key elements:

Introduction

For agricultural applications as well as for research work, often we need to prepare solutions of different agrochemicals of varying strength, as per the requirements. Agrochemicals are used to help crop plants grow, produce, and protect them from biotic/abiotic stresses. Many of the agrochemicals (insecticides, herbicides, fungicides, rodenticides, molluscicides, nematicides, etc.) are used to protect the crop from insect pests and diseases. However, some of them (fertilizers and soil conditioners) are used to augment crop yield. While in the previous chapter (Chapter 8) we discussed about preparation of laboratory solutions, in this chapter we will briefly discuss about the preparation of different agrochemicals.

Agrochemical/agrichemical is a generalized term used for the chemicals applied in agriculture. In general, it also includes the feed-supplements used in f isheries and animal husbandry.

Agrochemicals

Fertilizers

Fertilizers are used to augment growth of crop plants and to mitigate nutrient deficiency in the soil. Fertilisers can be organic (containing natural substances, prepared through natural processes) and inorganic fertilisers (synthetic fertilizers, manufactured artificially using chemical processes using natural deposits, by chemical alterations).

Soil Conditioners

Soil conditioners include manure, livestock and leaf compost, peat that help making the soil in good condition. They are laid on the top soil and then mixed properly. They not only increase nutrient contents in the soil but also improve aeration and water holding capacity.

INTRODUCTION
Depending on the product being made, different methods are used to prepare fruit-based products, including smoothies, jams, sauces, dried fruits, fruit preserves, and fruit juices. Specialized equipment is usually needed for each process in order to attain the required consistency and quality. Here is a summary of how various fruit-based products are made and an introduction to the standard tools used in their production.
SQUASH
This kind of fruit beverage has 40–50% commercially available total soluble solids and at least 25% fruit juice or pulp. Approximately 1.0 per cent acid and 350 ppm sulfur dioxide or 600 ppm sodium benzoate are also present. To serve, it is diluted. Commercial squash is made with mango, orange, and pineapple. Another way to make it is to use potassium metabisulphite (KMS) as a preservative for lemon, bael, papaya, etc., or sodium benzoate as a preservative for jamun, passion fruit, peach, plum, raspberry, strawberry, grapefruit, etc.
In India, people want cold beverages almost all year round. Acid squashes hold a significant position among these fruit juices. Due to their abundance of vital vitamins, minerals, and other nutrients, these are highly well-liked. Squash is a fruit beverage that has at least 25% fruit juice or pulp and at least 40% total soluble solids (sugar). Additionally, it includes 1-2 percent edible acid. Since squash has a relatively low sugar content, it should be preserved by adding an approved chemical preservative, such as sodium or potassium metabisulphite or sodium benzoate, along with flavour and colour. Fruits like mango, orange, pineapple, litchi, lemon, and so on can be used to make squash.

INTRODUCTION
The process of preparing vegetable-based products involves several essential steps, such as cleaning, chopping, cooking, and adding seasoning. Initially, vegetables are thoroughly washed to eliminate dirt and chemicals. Depending on the specific product, vegetables are then either peeled or chopped. Some vegetables undergo blanching to maintain their color and texture before they are frozen or subjected to additional processing. For products like vegetable soups, stews, or purees, the vegetables are simmered in water or broth to enhance their flavors.
The preparation process is supported by a range of equipment, including blenders for pureeing, steamers for gentle cooking, and slicers to ensure uniform cuts. Pressure cookers are used to speed up cooking times for items like stews, while dehydrators are employed to produce vegetable chips or dried snacks. Grinders and mills are used to create pastes or powders from vegetables. It is crucial that all equipment is handled carefully to ensure it operates effectively and safely, which is necessary for achieving the highest product quality. Regular maintenance of the equipment is vital for achieving consistent and reliable results.
VALUE ADDITION CONCEPT
Value addition is a strategic approach in post-harvest management aimed at enhancing the quality, market value, and economic potential of agricultural products such as fruits and vegetables. This process focuses on transforming raw produce into value-added products that are more desirable and useful for consumers and markets. It plays a critical role in modern agriculture, food processing, and marketing. Let’s take a closer look at the concept of value addition in post-harvest management:
• Product Diversification: Value addition involves creating a variety of products from raw fruits and vegetables. For example, fresh fruits can be turned into juices

1. Introduction

The increasing size and activities of humans have mounted severe pressure on the survival of other life forms on the earth. This is a matter of great concern for the humanity. Therefore, a critical study to inventory all plant species has become very essential and urgent before they are lost or become extinct. In the face of extinction of many of these species, we need to learn as much about them as quickly as possible. In the recent years there has been a great concern for biological diversity and conservation of biological resources. Although much emphasis has been given to the ways and means for inventories (Flora) of biological diversity, there is also need for more in depth studies that deal with basic relationship of species. Monographic, revisionary and systematic studies that provide basic descriptive information about organisms and their relationship are required to document the information and knowledge about the plant wealth of a country. This chapter is to highlights the usefulness of the Flora and revisionary studies, and provides the relevant information to the beginners and the budding plant taxonomists about the preparation of an ‘Ideal Flora’ and ‘Creative Revision’ to meet the requirement of the present time.

Background
During a fine needle aspiration biopsy (FNAB), a small amount of mammary tissue fluid is removed using a fine needle by applying suction, and cells present therein are identified in a thin smear. FNAB has been the most sensitive, quick, and precise tool for the differential diagnosis of malignancy. However, further research is required into the possibility of malignancy in dogs based on cytological evidence and candidate gene expression analysis. This is a noninvasive cancer detection technique and is often used in clinics.
Materials and Reagents Required
1. Fixative- cold acetone, ethanol, or aldehyde-based fixative (10% neutral buffered formalin/ NBF or paraformaldehyde).
2. Ethanol – 70%, 90% and 100%
3. Washing buffer (phosphate buffer saline)- PBS
4. Clean glass slides – preferably positively charged
5. 22-gauge needle fitted with 2 ml syringe
Procedures
Prepare for a dog having a mammary tumor
• Clean the site of the mammary tumor with alcohol and allow it to dry.
• Keep slides ready, clean, and dry.

42.1. Aim

To conduct practical on preparation of chutney from different fruits.

42.2. Theory

Fruit chutney is made in the same way as jam except that the spices, salt and vinegar or acetic acid is also added. In comparison to jam, chutney contains less total soluble solids. The product shall be of good quality with palatable and appetizing taste. As per FSSAI specifications, the chutney shall contain minimum of 40% fruit (w/w) in the final product with total soluble solids not less than 50%. The acidity in the final product shall not be more than 2 percent with ash content not exceeding 5 percent. Mixed fruit chutney is commercially made by using different fruits in appropriate combinations.

42.3. Raw material, ingredients, equipments and utensils required

1. Stainless steel peeling/cutting knives, pulper for extraction of pulp.

2. Utensils for cooking and mixing, ladle, glass jars, sterilization tank, diesel or LPG stove/bhatti etc

Fruit chutney is a product made in the same way as jam except that spices, salt, and acid (vinegar) in addition are added. The total soluble solids in chutney are] also less than that of jam. The product shall be of good quality with a palatable and appetizing taste. As per Food Safety and Standards Regulations, chutney\ shall contain a minimum of 40% fruit (w/w) in the final product with total soluble solids not less than 50%. The acidity in the final product shall not be more than 2% with ash content not exceeding 5%. However, for vegetablebased chutney as well as hot & sour (spicy) chutney, the TSS shall not be less than 25%.
Recipe: The generalized recipe for the preparation of chutney from different fruits is as under:

Jelly is prepared by boiling the fruit with or without the addition of water, straining the extract, and mixing the clear extract with sugar followed by cooking the mixture to a stage at which it will set to a clear gel. The jelly should be transparent, well set, but not too stiff, and have an original flavour of the fruit. It should be attractive in colour and should keep its shape when removed from the mould. As per FSSAI specification, the quantity of fruit and soluble solids in the final product (jelly and marmalade) shall not be less than 45 and 65 per cent (w/w) respectively. Jelly is made from fruit extract while jam is made from fruit pulp, therefore, jelly in contrast to jam is considered to be transparent and clear in appearance. Guava jelly is the most common commercial product.
Jellies: In the preparation of jellies, pectin is the most essential constituent which help in making the gel. Since, pectin is present in the cell walls of fruits as such fruit peel, whole or fruit slices along with a small quantity of water are gently boiled to extract the maximum proportion of pectin solution in the water extract. This water extract is used for the preparation of jelly.

Materials Required

Fruits juice, enzymes (pectinase, cellulase, pectinase CCM etc.), filter press, buchner filter apparatus, water bath, filter paper pulp, buchhi type rotary vacuum evaporator, freeze concentrator, membrane concentrator (whichever available), vacuum grease.

Procedure

    1.    Extract the juice as discussed in earlier exercises. Take a known quantity of juice in a conical flask.
    2.    Add enzymes i.e. pectinase @ 0.2% to the juice and keep in a water bath at temperature of 40-50ºC for 2 hrs.
    3.    Shake the flasks occasionally for uniform mixing of enzyme all throughout the flask during the enzymatic treatment.
    4.    Leave the flasks undisturbed for 10-12 hrs for allowing the insoluble solids to settle at the bottom of the flask.
    5.    Siphon the clear juice from the top of the flask.
    6.    Pass this siphoned juice through filter press or through a 0.4-0.5 cm thick bed of filter paper pulp in a Buchner filter apparatus or filter press.
    7.    Record the volume of the clarified juice obtained. Calculate the wastage.
    8.    Concentrate the juice in rotary vacuum evaporator at 50+2ºC temperature and at 28-30” Hg vacuum to a TSS of about 50 to 70º Brix. Record the exact TSS.
    9.    Record the volume of condensate obtained in the round bottom flask of the buchhi apparatus.
    10.    Calculate the folds of concentration

38.1. Aim

To prepare nectar from different fruit pulp/juice.

38.2. Theory

Fruit nectar is also a RTS drink but it contains not less than 150Brix TSS and not less than 20% fruit juice or pulp. It is preserved only by heat processing as such no preservative is allowed in fruit nectars. Mango nectar, guava nectar etc. are the commercial products in this category.

38.3. Raw material, ingredients and utensils required

1. Mango, guava, and pineapple nectars are commercially available in the market. However the nectar can also be prepared from a number of other fruits like jamun, aonla, apricot, papaya, plum and bael etc.

Fruit syrup is a beverage that contains at least 25% fruit juice/pulp, 65% total  soluble solids and acidity ranging between 1.2 -1.5%. It is preserved by using
350 ppm SO2 or 600 ppm benzoic acid. Fruit syrup is diluted before serving. Syrup can be made from the juice/pulp of jamun, ginger, lemon, phalsa, rose extract, bael, pomegranate, and brahmi (Bacopa monnieri) leaves/root extract, etc. Besides, a syrup/sharbat containing a minimum of 10 per cent of dry fruits is also regarded as fruit syrup.
Recipe: The generalized recipe for the preparation of syrups from different fruits is as under:

Materials Required

Apple (or any local fruit), fruit mill, hydraulic press, weighing balance, Refractometer/sugar pectinol, diammonium hydrogen phosphate, Saccharomyces cerevisiae culture, Potassium metabisulphite (KMS) etc.

Procedure

    1.    Take a known quantity of apple (or any other fruit) say 20 Kg
    2.    Extract the juice as discussed in earlier exercises.
    3.    Add about 200 ppm of kms.
    4.    Add sugar syrup to increase the TSS to about 20 – 24ºBrix.
    5.    To about 10 Kg of juice diammonium hydrogen phosphate (10 g) and pectinol (20-25 g are added).
    6.    Take about 500 ml of this mixture in a conical flask and add pure Saccharomyces cerevisiae culture @ 1 % and plug the neck with cotton. Keep at 22-24ºC to complete the fermentation within one day and yeast culture is ready.
    7.    Add this culture to about 10 Kg of must for further fermentation (i.e. culture is added @ 5% therefore 500 g is added to 10 Kg must).
    8.    Record the TSS of the must before fermentation.
    9.    Keep must for fermentation in big jars (narrow mouth) filled to about 75 % of their volume. Close the mouth of jars or bottles with cotton plug.
    10.    Allow fermentation to take place at 22-24ºC for about 10–15 days.
    11.    When no more bubbles are coming out of the jars, fermentation is complete. At this stage the TSS reaches about 7º Brix.
    12.    Siphon the wine. Add filter aids if wine is not clear.
    13.    Blend the wine with sweetening agents if required.
    14.    Fill in beer bottles by keeping a head space of about 2.5 cm followed by crown corking them.
    15.    Pasteurize the bottles by keeping at 62.5ºC for 20 min.

INTRODUCTION
The production of products from grains, pulses, and oilseeds entails a series of processes aimed at converting raw agricultural materials into products that are ready for use or consumption. These processes typically take place in dedicated facilities like grain mills, pulse processing units, and oilseed crushing plants, where various types of equipment are employed at different stages of production. Below is an introduction to the main processes and an overview of the equipment commonly used for these operations.
The preparation of grain, pulse, and oilseed-based products plays a vital role in transforming raw agricultural produce into consumable goods, contributing significantly to food security and nutrition. These products are integral to the daily diets of people around the world, and the processes involved in their production are designed to enhance quality, shelf life, and marketability. The procedures that go into preparing these products vary depending on the type of raw material, but all involve a series of specialized steps that are typically carried out in dedicated processing facilities.Grain mills, pulse processing units, and oilseed crushing plants are the primary settings where these transformations take place. Each of these facilities is equipped with specific machinery to perform tasks such as cleaning, milling, sorting, and packaging, with the aim of creating high-quality end products that are ready for distribution. The operation of these different pieces of equipment is crucial for ensuring consistency in quality, efficiency in production, and minimal wastage.
The processing of grains, pulses, and oilseeds involves several stages, such as cleaning to remove impurities, grinding or crushing to break down the raw materials, and packaging for storage or shipment. Each stage requires different equipment, such as mills for grains, crushers for oilseeds, and sorting machines for pulses. Understanding the operation of these machines is essential for anyone

Pharmaceutical and chemical industries depend largely on toxicological evaluations to provide information regarding safety of their commercial products. Toxicologists so far have been relying on animal studies to investigate potentially beneficial or harmful effects of drugs and chemicals prior to testing them in humans. Traditionally, the safety assessment process during drug development has been based on screening indiscriminately a plethora of new chemical entities (NCEs) using a large number of animals as testing models in order to identify new therapeutic agents with the expectation that one or a few of these NCEs have some competitive advantages over the existing therapeutic agents. That is why they are more efficacious, bioavailable, selective, and safer. This approach is costly, time-consuming, and requires large quantities of test material. Currently, it takes about 10-12 years and a huge expenditure for a drug to move from research laboratory to patent. Thus alternative cell culture models in the early phases of the drug discovery process can save time and money both by eliminating least beneficial NCEs.

Preparation of Reagents

Culture media

For the culture of hepatocytes medium M199 (GibcoBRL, USA) is used. One pouch of the dry media is dissolved in 1 liter of filtered distil water. The pH of the media is adjusted by adding 0.4% sodium bicarbonate to be around 7.4. The media is than sterilized by filtration through seitz filter (0.22 mm) and stored in 50 ml sterilized conical flasks.
