Determination of True Protein

Apparatus

Wide mouth stoppered bottle, water bath plus those used for total nitrogen (crude protein) determination.

Reagents

1. Saturated solution of potash alum.
2. Stutzer reagent-Dissolve 40g of CuSO₄ in 2 litres of water in a wide mouth stoppered bottle. Add 10ml of glycerine and sufficient quantity of 30 % NaOH to make the solution alkaline (Litmus paper). Shake the contents and allow to settle. Discard the supernatant liquid. Collect the precipitate on a filter paper and transfer it to glass mortar with the help of spatula. Add 3ml of glycerine and a little water in the mortar and triturate the precipitate with a glass pastle. Transfer the triturated material to a wide mouth stoppered bottle, add 600ml of water, shake well and filter. Repeat the process till the precipitate (filtrate) is free from alkali and sulphate. Collect the precipitate and add 30ml glycerine. Dilute the emulsion to 320ml with water and preserve in a container.

After doing all hard work during fruit production the last operation is harvesting on field. Though it is last operation, it should be done very carefully to get the quality harvest. Harvesting of fruits mainly depends upon the nature of fruit. Here nature refers to the classes of fruits divided on the basis of their respiratory pattern and ethylene production. On the basis of the respiratory pattern the fruits can be divided in to two categories, first one is climacteric and the second one is non climacteric.

1. Climacteric fruits: The meaning of word „climacteric is a critical period or event. Here, climacteric refers to the event of respiratory rise before the ripening phase. Those fruits which show such patterns are known as climacteric fruits (Taiz and Zeiger, 2002) Examples: Mango, guava, apple, banana, sapota, papaya, peach, pear, plum, fig, Annona.
2. Non climacteric fruits: Non climacteric fruits do not exhibit the respiration and ethylene production rise (Taiz and Zeiger, 2002). Examples: Citrus, grapes, pineapple, pomegranate, litchi, ber, jamun, cashew, cherry, strawberry.

Theory

Paddy parboiling is a hydrothermal process where the paddy is partially boiled to gelatinize the starch. During the gelatinization process the void of the rice kernel are filled and become hard on drying resulting minimum breakage and maximum head rice recovery. The nutrients are also absorbed into the inner mass and loss of nutrient is avoided. In general, the steps are involved in parboiling process are (i) Soaking (ii) Steaming (iii) Drying.

Like all the carbons, this remedy is an antipsoric of great power, but especially active in patients who are rather stout, of fair complexion, with tendency to skin affections and constipations, fat, chilly, and costive, with delayed menstrual history, take cold easily.

Children impudent, teasing, laugh at reprimands. Anaemia with redness of face. Tendency to obesity.

By and large, Graphites is a skin remedy. Eruptions oozing out at thick honey - like fluid require Graphites. Such eruptions may be on any part of the body. These would be especially found on or beyond the ears, on the head, the face and the genitals or on the eyelids.

Graphites is indicated in eczema of the legs where there is a thick oozing of sticky fluid. Eczema of the eyelids, where the eruptions are moist and the margins of the eyelids are fissured, also requires Graphites.

18.1 Introduction

Among nut crops, ‘Walnut’ or ‘Akhrot’ is the most important crop. It has immense commercial importance even in the areas situated in remotes without having good market and transport infrastructure. Because of long storability, growers have opportunity to hold the produce at room temperature for two to three months easily and sell out at intended time. Walnut is rich in protein, fats and vitamins, especially vitamin B6 . The walnut kernel contains about 90% PUFA of which 26% is the Omega-3 fatty acid, alpha-linolenic acid. But the problem with this type of kernel is that higher the percentage of PUFA in it, the more is the chances of getting the oil oxidized and thereby reducing the shelf life of the walnut kernel.

Deterioration of Crop varieties in their genetic endowments/qualities has been explained by Kadam (1942). Publication on maintenance and management of breeder seed production (Laverack 1991), and maintennce of self pollinated crop varieies (De Hanns 1953; Parlevliet 2007) explain in detail various aspects in maintenance of the seed quality.

Feed processing includes all operations necessary to achieve the maximum potential of nutritional value of a feed stuff. The process involves changing ingredients in such a manner as to maximize their natural value and the net returns from their use. Feed processing may be accompanied by Physical, Chemical, Thermal, Bacterial or other changes of a feed ingredient before it is fed. The primary reasons for processing feeds are to make changes in the moisture content, density of feed, particle size, palatability; or to make more profit, to improve nutrient availability, keeping quality (shelf – life); or to reduce storage – transportation space, cost, moulds, Salmonella and other harmful substances. Feed mill equipment: The milling industry has been concerned with “Grinding” – a process of particle size reduction. During
earlier times, the same equipment was used Food for humans to produce Food for livestock because, the process was basically ‘grinding’ of whole grains. As milling developed into the “Modern Flour Industry”, the milling process was extended to include:

Wettable powder (WP): An insecticide formulation consisting of finely ground solid particles of active ingredient plus inert carrier; forms a suspension when added to water.

Waggle dance: A communication dance of honey bees. A form of recruitment in the honey bee in which direction and distance to a food source are indicated.

Waiting period: See time interval.

Waiting period: The prescribed period between last application of a pesticide to crop and harvest.

Warble: The swelling on the host body caused by the larva of a warble fly.

Warm-blooded (Homoiothermous): Animals in which body temperature normally does not change with changes in atmospheric temperature e.g.birds and mammals.

Warning: Signal word used to designate a moderately toxic pesticide; oral LD₅₀ = 50 to 500 mg/kg body formulated.

Feedback

Feedback’s influence on learning is indisputable and undeniable and feedback’s varying roles in instruction are heavily researched concepts (Mory, 1992). Understanding how feedback facilitates, and, in some cases, hinders transfer of knowledge is essential to creating effective instruction.

Researchers have focused on the many aspects and roles of feedback in hopes of developing some synthesis that will increase learner performance and improve instruction. Researchers such as Bangert - Drowns, Kulik, Kulik and Morgan (1991), Brinko (1993), Clariana, R.B. and Lee, D. (2001), Clariana, R.B., Wagner, D. and Rohrer-Murphy, L.C. (2000), Kulhavy (1976), Kulhavy and Stock (1989), Kulik and Kulik (1988) and Mory (1992) to name only a very few, have sought to discern the complex role feedback plays in learning. While many studies have been convincingly conducted trying to ascertain how feedback best works in certain circumstances, a consensus has yet to be reached in most, if not all, areas and as Clariana (2000) writes, “There are a number of unanswered questions and perhaps even more unquestioned answers”.

Rubber-roll Sheller consists of two rubber rolls rotating in opposite direction at different speeds. One of the roll is fixed while the other is adjustable to obtain desired clearance between them. The rolls are driven by mechanically. The adjustable roll normally runs about 25% slower than the fixed one. A feeder feeds paddy uniformly to the machine (Fig.27.1). Paddy is fed in thin layer through the clearance between two rubber rolls, rotating in opposite directions at different speed. Difference in speeds of the rolls develops a shearing force on grain surface results in the splitting, breaking and separating the husk from the grains. One part of the husk is subjected to shearing forces whereas the other part in contact with the slower roll is under compression and is thus subjected to breaking forces. Husking is done by the action of these forces. The clearance between them should be smaller than the mean thickness of paddy and may be adjusted subsequently by judging the shelling efficiency. If the gap between rolls is properly adjusted, it can shell up to 95% of paddy fed to it. At decreased gap excess pressure results more breakage of grain and can also cause coloring of shelled rice. During shelling the faster roll should have a peripheral speed of 10 -13 m/ s, while the slower roll 8-10 m/s.

Suits especially scrofulous and lymphatic constitutions that are inclined to have eruptions and glandular swellings. Unhealthy skin. Blondes with sluggish character and weak muscles. Great sensitiveness to all impressions. Sweating patient pulling blanket around him. Chilliness, hypersensitiveness, splinter-like pains, craving for sour and strong things are very characteristic. The tendency to suppuration is more marked, and ahs been a strong guiding symptom in practice. The side of the body on which he lies at night becomes gradually insufferably painful; he must turn.

Hepar Sulph is the medicine for abscess, for the tendency to suppuration. Every little injury suppurates. Accompanying this suppuration is shooting pain. Suppuration or pus formation can be on any part of the body. If throbbing and shooting pain accompany it, it requires a does of Hepar Sulph in a high potency of 200 and above. Hepar Sulph can abort pus formation if given at the earliest stage of suppuration. Later it will hasten the pointing and discharge and help in healing the ulcer.

Duck (Anas platyrhynchos) is one type of indigenous poultry species, reared traditionally by the poor farmers for their livelihood. Maximum numbers of duck flocks concentrate in the paddy (Oryza sativa) growing and watershed areas of the state like Assam, Bihar, Manipur, Kerala, Andhra Pradesh, Tamil Nadu, Orissa, and Tripura. Ducks rise on the free-range system with readily available fallen grains in paddy fields, insects, snails, earthworms, small fishes, and other aquatic materials. 

Ornamental fish trade is a part of the culture of fisheries in India and is an important sector for livelihood and income generation, especially for women. Recent trends in production and demand share assume that during the next five years, domestic trade will double from the present. The growth of any business depends on technology, management, market, and infrastructure. The ornamental fish industry includes breeding of exotic live-bearer and egg layer fish, captive breeding of indigenous ornamental fish, the development of small-scale enterprises, backyard fish breeding and culture activities in rural areas, and ancillary units with high potential for large- scale exports as part of the multibillion-dollar global trade of the ornamental fish sector. Women are sensible and caring enough to take care of and nurture the small, tiny, colourful fish in their backyard units of ornamental fish. One of the important sectors of the ornamental fish industry is aquarium making and decoration, which is not only women friendly but also ensures earnings.

Water vapour transmission rate of packaging material

Introduction

Moisture Vapor Transmission Rate (MVTR), also known as Water Vapor Transmission Rate (WVTR), measures the rate at which water vapor passes through a material. MVTR is crucial in various industries where moisture control is vital. For example, moisture-sensitive foods and pharmaceuticals are packaged using materials with controlled MVTR to ensure quality, safety, and shelf life. In the textile industry, MVTR serves as a measure of breathability, enhancing comfort for outdoor clothing. In the building materials industry, managing moisture barrier properties in architectural components helps maintain appropriate moisture levels in the internal spaces of buildings. Various techniques are used to measure MVTR, ranging from gravimetric methods that assess moisture gain or loss by mass to advanced instrumental techniques capable of measuring extremely low transmission rates. It's important to note that special care must be taken when measuring porous substances like fabrics, as some techniques may not be suitable.

Anti–nutritional factors: Detoxification of undesirable components is very important, because some feeds may contain toxic substances, the excess consumption of which may cause decreased nutritive value of the feeds or may injure some vital organs or even cause death. 
Points to ponder
• Anti – nutrients present in the diet, either by themselves or their metabolic products arising in the system.
• Plants evolved these compounds as defensive mechanism against insects, parasites, bacteria and fungi.
• Feeds high in anti – nutrients: Lectins = legumes, cereal, grains, seeds, nuts, fruits, vegetables. Oxalates = spinach, swiss chard, sorrel, beat greens, beet root, rhubarb, nuts, legumes, cereal grains, sweet potatoes, potatoes. Phytate [IP6] = legumes, cereal grains, pseudo – cereals (amaranth, quinoa, millet), nuts, seeds.
• Anti – nutrient in wheat: Phytate being the most important among all, reduces the bio – availability of Iron and Zinc. There could be protease inhibitor, tannin, lectin, alkaloid, oxalate too.
• Main anti – nutrients in edible forage and fodders are: tannin, saponins, phytic acid, gossypol, lectin, amylase inhibitor, goitrogen, protease inhibitor.
• Removal of anti – nutrients: heating, boiling, soaking, spouting, fermentation. By combining different methods, many anti – nutrients can be degraded completely.

Specifications

These structures are generally used for the storing grain in the bags. The length of the structure is about twice the width or greater than that. Special care should be taken to make the side walls, floor and roof in constructing the structure. The walls are made of bricks or stones laid either in lime mortar (1:2) or cement mortar (1:6). The thickness is restricted to a minimum of 37.5 cm or maximum of 45 cm. The height of the walls on which the trusses are placed is kept about 5.5 m. Each of the structures is provided with two large size doors of 2.4 × 2.4 m and top ventilators.

The name Ipecacuanha is from the Portuguese meaning, 'Road-side-sick-making plant⁷, and mention of it as a remedy for the bloody flux or dysentery goes back as far as the late sixteenth century.

The principle feature of Ipecacuahna is its persistent nausea and vomiting, which form the chief guiding symptom. Indicated after indigestible food, raisins, cakes, etc. especially indicated in fat children and adults, who are feeble and catch cold in relaxing atmosphere, warm moist weather.

One cannot think of treating persistent nausea without Ipecac. This is a nausea in which there is no relief by vomiting. The patient is as sick after as before. The second major problem for which Ipecac is a great cure is a chest complaint, bronchitis in infants, bronchitis with coarse rattling. Ipecac is also a remedy for infections of the upper respiratory tract wherein a peculiar wheezing sound is produced on breathing out. Old incurable cases of asthma are relieved by Ipecac. Ipecac is useful in uterine haemorrhages.

Potassium availability in most of the coastal salt affected soils of India is rich except when the soils are low in clay content (Bandyopadhyay et al., 1985). Plants grown under high salinity may show K deficiency due to the antagonistic effect of Na on K absorption and / or disturbed Na / K ratio. Under such conditions application of K is also known to reduce the adverse effect of salinity and sodicity on crop growth (Qadar, 1995). Singh et al. (1980) reported that the addition of FYM increased the K concentration in the soil. Swarup (1987) reported that the incorporation of green manure increased the available N, P and K status of the soil. Available P and K remarkably increased to a tune of 30 and 44 per cent respectively by the application of coir waste (Santhi et al., 1991).
