Shock is a life threatening condition which is usually manifested by serious pathophysiological abnormalities. In most cases it is due to poor tissue perfusion with impaired cellular metabolism.

       It is a clinical state resulting from an inadequate supply of oxygen to the tissues or an ability of the tissues to properly use oxygen.

       Shock can also be defined as imbalance between oxygen supply and oxygen consumption. In other words, the delivary of oxygen does not meet the needs of the tissues.

       Shock is a state in which the vital functions of the body are depressed because of acute reduction in cardiac output and effective circulating blood volume.

ABSTRACT

Microbial contamination is perceived as the most serious threat faced by plant tissue culture research laboratories and commercial production units. A culture is often viewed as contaminated when obvious microbial growth incited by fungi, yeast or bacteria is noticed on the culture medium. On the other hand, there can be situations when microbes may be present in a covert or latent form with serious side effects on the cultures. The present investigations were taken up with the objectives of elucidating the cause of poor growth, lack of regeneration response or modification of rooting observed with visibly clean cultures of different horticultural crops. Apparently clean cultures of grape, banana, watermelon, eggplant, gerbera and chrysanthemum of recent origin or after long-term in vitro culturing were used in this study. Indexing the medium of such cultures using fungal/ yeast and bacteriological media brought out the covert association of one or more bacterial types with varying proportions of incidence in such cultures. Indexing of tissue revealed bacterial presence in different parts of in vitro plantlets. In some instances, bacteria showed endophytic colonization while being not detectable in the tissue culture medium subsequent to a disinfection or antibiotic treatment. Such bacterial association appeared to be the cause of in vitro decline observed with long-term micropropagated cultures, lack of reproducibility of tissue culture protocols, failure of in vitro rooting etc. besides being a threat to in vitro gene banks and germplasm exchange.

Frequently referred to as "vegetable confetti," microgreens are produced from a variety of commercially grown food crops, including cereals, vegetables and herbs. They contain completely formed cotyledons that may or may not have partially extended genuine leaves (Treadwell et al., 2020). Seven to twenty-one days after germination, the exact piece of the delicate plant's growing stem is removed, along with the cotyledon leaves and maybe the real leaves (Galieni et al., 2020). Despite their small size, these useful micro veggies offer exceptional sensory qualities, including flavour, texture, scent, look and unusual colours. They normally have a height of 2-8 centimetres.

Evaluating the Evaluation

In this chapter, the essentials of basic statistics are explored, with a focus on obtaining all key measures of basic statistics with just a single click. Additionally, the process of creating informative data distribution graphs is also explained.

Basic Statistics

Basic statistics offer fundamental tools that help us to make sense of data. Below, you’ll find concise descriptions of key basic statistical measures.

i. Arithematic mean (average)

The average represents the central value of a dataset, calculated by summing all values and dividing by the number of data points.

ii. Median (middle value)

It is the middle value in a dataset when all values are arranged in ascending order. It’s less sensitive to outliers.

iii. Mode (most common value)

The mode is the value that appears most frequently in a dataset.

iv. Variance

Variance measures how much individual data points deviate from the mean. A higher variance indicates a greater spread.

v. Standard deviation

The standard deviation is the square root of the variance. It provides a measure of how spread out the data is.

vi. Range

It is the difference between the maximum and minimum values in a dataset.

INTRODUCTION
The lubrication system in an engine plays a critical role in maintaining the smooth operation of its components. It serves to create a barrier between two surfaces that are in contact and moving against each other, reducing the friction that would otherwise lead to wear and tear. To understand the importance of lubrication, consider the effect of friction when two surfaces rub together; much like when rubbing your hands, friction generates heat, which over time can cause damage, such as burns to the skin. In the context of an internal combustion (IC) engine, friction between its moving parts can result in similar consequences, including excessive wear, heat buildup, and power loss, which ultimately impair engine efficiency and longevity.
The internal combustion engine consists of various moving components that are subject to constant friction as they operate. The pistons, crankshaft, camshaft, and valve mechanisms all move at high speeds within confined spaces, leading to the gradual wearing away of metal surfaces. Without proper lubrication, this friction would not only damage the engine’s components but also result in overheating and a significant reduction in the engine’s performance. The heat generated by this friction can increase the risk of engine failure, as it can lead to parts seizing or warping under high temperatures.
To combat these issues, the lubrication system is designed to reduce friction, dissipate heat, and protect the moving parts from wear. It ensures that a thin film of lubricant is constantly supplied to critical areas of the engine, forming a protective layer between metal surfaces. This helps to minimize direct contact between the moving components, thereby reducing friction and preventing unnecessary wear.
Moreover, lubrication contributes to cooling the engine by carrying heat away from the friction zones and dispersing it throughout the engine system.

Pollu beetle: Longitarsus nigripennis:Chrysomelidae

This pest is monophagous to pepper and no alternate host has been reported so far.

Nature of Damage

Adult is a shining blue flea beetle with yellow head and thorax and has thick enlarged femur and tibia. The adult beetle is only the size of a pin head.  The infested berries dry up and turn dark in colour. Berries become hollow and crumble when pressed and such hollow berries are called “Pollu” meaning empty. The eggs are laid on the berries @ 1-2 eggs in each hole. Eggs hatch in 5-8 days. The grub period extends for 30-32 days. The emerging grubs feed on the berries of pepper and consume the internal contents.

The arid region in India is spread over in 38.7 million hectare land. Out of the total 31.7 m hectare lies in hot arid region and remaining 7 m hectare comes under cold arid region. The hot arid region occupies major part of northwestern India (28.7 m ha) and a small pocket (3.13 mha) in southern India. The north western arid region occurs between 22°30’ and 32°05’ N latitude and 68°05’ to 75°45’ E, covering western part of Rajasthan, north western Gujarat and south western parts of Haryana and Punjab. About 62% area of arid region falls in western Rajasthan and 20% in Gujarat. Haryana and Punjab together constitute 7% area of arid region. The state wise distribution of arid region is shown in Table 3.1. Further our discussion is based on the majority area of arid region, belonging to Rajasthan, Gujarat, Punjab and Haryana.

Liver is the largest exocrine gland located in right side of the abdominal cavity
obliquely from lumbocostal angle downward and forward to intercostal space,
about 3-4” (10 cm) above the abdominal floor.

In several cucurbits as well as other crops, BER is a physiological condition found (for example, tomato, brinjal and pepper). It typically occurs as a general rot at the flowering end of rising fruit. Usually, the blossom end rot is the result of inadequate or uneven irrigation, high humidity, or other variables that slow the flow of water through the plant. Slow water movement may also result in temporary calcium deficiencies leading to blossom end rot as calcium is added into the plant with the transpiration stream.

Through a detailed examination of traditional and innovative soil management strategies, such as crop rotation, cover cropping, conservation tillage, and soil amendments, the article provides comprehensive insights into maintaining and improving soil health. By understanding and implementing these practices, farmers and stakeholders can ensure long-term agricultural productivity and environmental stewardship.

(Chroma - Colour; Some - Body)
A chromosome is a thread-like self-replicating genetic structure containing organized DNA molecule package found in the nucleus of the cell. Clear and detaile decriptions of mitotic chromosomes in plants and animals were published by Strasburger in 1875 and by the German scientist Walter Flemming in 1879- 1882.Heinrich Wilhelm Gottfried Waldeyer coined the term chromosome in 1888.
Normally Chromosomes are of two types
Autosomes - Control characters other than sex characters or carry genes for somatic characters.
Sex chromosomes (S    
Humans and most other mammals have two sex chromosomes X & Y, also called heterosome, odd chromosome, or idiosome. Females have two X chromosomes in diploid cells; males have an X and a Y chromosome. In birds the female (ZW) is hetero-gametic and male (ZZ) is homo-gametic.
Haploid: Haploid cells (N) have only one copy of each chromosome.
Diploid: Diploid cells (2N where N- chromosome number) have two homologous copies of each chromosome. The body cells of animals are diploid.In animals, gametes (sperm and eggs) are haploid.
Homologous Chromosomes
Diploid organisms have two copies of each chromosome (except the sex chromosomes). Both the copies are ordinarily identical in morphology, gene content and gene order and hence known as homologous chromosomes.Each pair of chromosomes made up of two homologs.
Homologous chromosome is inherited from separate parents; one homolog comes from the mother and the other comes from the father.

The atmospheric pressure is weight of the air which lies vertically above an unit area centered at a point. Normal pressure of air is 1.034/cm².

Pressure is defined as the force per unit area.
At the surface of the earth the atmosphere air exerts a pressure of about 10⁵ Newtons/m² or 10⁵ Pascals, which is called one bar or one atmosphere. Evangelista Torricelli (1608-1647) devised a method for measuring the atmospheric pressure by mercury (Hg) barameter in 1643.

The understanding of VAM symbiont and VAM symbiosis is of prime importance in manipulating VAM associations for the welfare of plants. Many contributions have been made worldover in the areas of taxonomy, morphology, anatomy, histology, cytology and genetics of VAM fungi and/or their associations with the plants. However, the share of Indian mycorrhizasts in such contributions is negligible. The following description gives an account of work done by the mycorrhizasts of the country in these areas.

Soil sampling is an integral and essential component of soil fertility evaluation and nutrient management research. The effectiveness of soil sampling is a prerequisite for soil testing to achieve its goals for efficient nutrient management and plant nutrition for improved yield and quality. The underlying basis for soil sampling is that a soil sample taken represents the “population” which may be a plot, field or a watershed. It further implies that nutrient status of the representative soil sample(s) determined in a laboratory would reflect nutrient status of a plot, field or watershed and is of interest for correcting nutrient disorders in the field or watershed.

The most important factor that influences the effectiveness of soil sampling is soil heterogeneity. However, in a relatively homogenous group of fields or plots, a small number of samples may be sufficient to represent the population to a more heterogenous group of fields that would require more number of samples to represent the soil population. Whenever, soil samples to be taken in field following points needs to be kept in mind.

Knowledge of fertilizer dose, selection of fertilizer sources, time and method of application is essential for achieving efficient use of fertilizers and profitable yield.

A. Fertilizer Dose

Fertilizer dose for crops is determined based on the field experimentation. It varies with the crops and varieties, initial fertility of the soil, soil properties, cropping system, climate, season, rainfed or irrigated crop, expected yield etc. Fertilizer dose for rainfedcrops (Kg/ha)

It investigates the current Internet-mediated communication practice in the twin city (Bhubaneswar and Cuttack) of Odisha and explores the social and cultural implications of the new communication mode.

This is one of the most serious difficulties in mango farming since it makes mango agriculture less rewarding for farmers. In one year (a year) and very little or no harvest next year, mango trees appear to bear huge crops (off year). This bieniality is therefore also present in normal ranges (Singh, 1990).
