7.1.1. Colletotrichum

The pathogen forms a large number of acervuli on the infected parts. The conidiophores are slightly curved, short, and club-shaped. The conidia are hyaline and falcate, borne singly on the conidiophores. Numerous black colored and thick-walled setae are also produced in acervulus. In culture, most isolates produce cottony, fluffy, or suppressed colonies (Fig. 7.1).

ABSTRACT

The purpose of this paper is to utilize thermal infra red remote sensing data to find the location of heat processing units which contribute to high temperatures. These industries occur as anomalous pixels in urban area on the temperature map derived from the thermal remote sensing data. The night scenes of ASTER thermal infra red data were used for this study. It is concluded that analysis of temporal thermal remote sensing data can be used as a tool in environmental impact assessment and management. The temperature maps can be helpful in decision making process of siting / relocation of heat producing industries in and around cities.

1. INTRODUCTION

For sustainable industrial development, management and regular monitoring of the industries is needed. Knowledge of industrial impacts on the environment is an essential for environmental impact assessment and management. Thermal remotes sensing techniques can be applied for this.

1. Introduction

In the last few decades there has been worldwide revival on the use of herbal drugs/phytochemical for diverse purposes including medicinal, nutritional and as cosmetic. The revival of interest in natural drugs and the herbal products was due to the widespread belief that ‘green’ medicine is healthier than synthetic products. This has led to the rapid spurt of demand for health products like herbal tea, ginseng and such products of traditional medicine during the 1980s. The health promotion and disease prevention strategy in treatment is widely prevalent in oriental systems, especially the Indian (‘Ayurveda’, ‘Siddha’, ‘Unani and ‘Amchi’) and the Chinese systems of medicine, which are finding increasing popularity and acceptance in the world over. Because of this sweeping ‘greenwave’ a large number of herbal drugs and the plant derived herbal products are sold in the health food shops all over the developed countries. Export– Import Bank reports revealed that the global trade of plant-derived and plant originated products is around US $60 billion (with growth of 7% per annum) where India holds stake of US $1 billion which is expected to reach 3 trillion US$ by the end of 2015 (Pandey et al. 2008). These targets can be achieved by providing scientifically validated, safe and standardized herbal products in domestic and international markets.

Standardization is an important step for the establishment of a consistent biological activity, a consistent chemical profile, or simply a quality assurance programme for production and manufacturing of herbal drugs. It is now well known that the pharmacological activity of a medicinal plants is due to the presence of certain bioactive phytochemicals, which are either primary or secondary metabolites. Amount of these compounds are controlled and conditioned by a variety of factors such as its genetic predisposition, habitat of the plant agro climatic conditions, season and also the stage of growth and development of the plant etc. Therefore, it is desirable to study the effect of these on secondary metabolites to get the right/optimum amount of secondary metabolites in the plant part/raw drug. The formation of herbal drug based on the traditional knowledge using modern tools is the requirement of the present day. WHO’s specific guidelines for the assessment of the safety, efficacy and quality of herbal medicines as a prerequisite for global harmonization are of utmost importance. Considering the importance of the herbal drugs/products, quality assurance of raw drug/formulation and developing botanical and chemical parameters for assuring their quality, have become major riders on the pharma or drug research and industry.

Blood Sample collection

Blood samples (5 ml per goat) will be collected aseptically from the jugular vein in a vacutainer tube (B.D. Bioscience, Germany) containing EDTA as anticoagulant and transferred to the laboratory in an ice box.

Isolation of Genomic DNA

The Genomic DNA will be isolated from the blood samples by ‘Phenol: chloroform isolation’ method as described by Sambrook and Russel (2001). The steps for isolation of genomic DNA are as follows:

INTRODUCTION

Fishing is one of the oldest professions of humans. As the day went by, the fish farmers carry out their own indigenous technology as a common practice through natural resource management. In this line, different traditional fishing communities of West Bengal gained a vast experience in every sphere of aquaculture. Their innovation is based on their own knowledge derived from their day to day effort of solving problems. Actually this indigenous knowledge is the accumulated information, skill and technology of the local farmers derived from the close interaction with the nature. The intimate interaction of the farmers with aquatic ecosystems through their age old practices has developed huge expertise which is essential to be documented and disseminated. It will be helpful for aqua resource management as they can be shared in a, cost effective, eco-friendly as well as socio economically viable proposition.

Identification of key communicators
For effective introduction of innovations and transfer of technology among farmers, effective communication is the prime need. An extension worker passes his information more effectively if he communicates with farmers/livestock owners through local leaders and key communicators.
Leader:  Is a person who effectively influences a group to cooperate in setting and achieving the goal.
Leadership: Leadership is a process by which an individual influence, guide and direct the thought, feelings and impressions in desired way.
Key communicators: Key communicator is a person who has maximum information about his society and vicinity area on different aspects.

Objective
After performing this experiment you will be able to learn:
Identification of paper and paperboard.

Introduction

Paper can be broadly classified into two categories: coarse papers, which are normally made of unbleached Kraft softwood pulp and used for packing, and f ine papers, which are usually composed of bleached pulp and used for writing paper, bond, ledger, book, and cover sheets.

The main types of packaging papers are:

Kraft paper

Usually produced on a Fourdrinier machine, kraft paper is gritty and incredibly strong. It is then either machine-glazed on a Yankee dryer or machine-finished on a calendar. Sometimes it isn't calendared so that the rough surface will keep the bags from slipping over one another when they're stacked on pallets.

Mange or parasitic dermatitis is caused by the infestation of mange mites e.g. Sarcoptes, Psoroptes, Demodex spp. and a range of other mites. The condition is characterized by itching, rubbing of the infested parts of the body against hard objects. Lesions include hair loss, dry, rough, thickened and wrinkled skin accompanied by the presence of scab and foul odour in some cases. Some mites burrow into the host epidermis (Sarcoptes) while others spend their entire life cycle on the skin surface (Psoroptes). Most mites are microscopic or less than 1mm in length; therefore skin scrapings are taken from the affected area of animals suspected to be suffering from mange or parasitic dermatitis.

ABSTRACT

The study was aimed to identify and delineate the groundwater potable zone in and around Madurai region. The study area is composed of Charnockites and Khondalites of Archaean age. The information of lithology, geomorphology and land use/land cover was generated using the Resourcesat (IRS P6 LISS IV data) and Survey of India (SoI) toposheets of scale 1:50,000 and integrated them with GIS to identify the groundwater potable zones of the study area. On the basis of hydrogeomorphology, groundwater potential zones was identified and delineated. From the overlay analyses landuse and EC, it is inferred that, poor category groundwater is found in the scrub forest, current fallow, canal and scrub with land areas.

Abstract

High Altitude zone is comprised of 40 mandals distributed in parts of Srikakulam, Vishakhapatnam, East Godavari and Khammam districts of Andhra Pradesh covering a geographical area of 1.8 m. ha. The area of this zone lies between 50 to 1680 MSL and is characterized by high slopes, mountains, hills and hillocks as part of Eastern Ghats. Red soils are the most predominant type (94.8%). A small area is covered under alluvial soils and coastal sands. The mean annual rainfall ranges from 1245 to 1288 mm of which about 70 per cent is contributed by southwest monsoon. Large geographical area (58.9%) in the zone is under forests and the net cropped area is only 19.2% with very little irrigation sources. The tribal people of this area practice shifting cultivation locally known as “podu” cultivation for their subsistence. Rice is the most important crop in the zone occupying 36.2 per cent of the gross cropped area of 0.42 m. ha. The other principal crops grown are millets, mesta, niger and tuber crops. Tea, coffee and other plantation crops are also grown in addition to aromatic and medicinal plants. Cropping intensity is 120 per cent. Forest produce such as honey, gum, soap nuts, tamarind fetch income to the tribal people (www.angrau.net).

This assignment focuses on various methods in identifying the rural or local leaders in the social system and helps the students in case of identifying the specialized roles of extension workers at grassroot level.

PURPOSE

To identify rural leaders for collecting information about the village.

To assess the role of rural leaders in transferring new technology to the villagers through rural leader.

Objective: To identify salt tolerant genotypes by Glycine Betaine (GB) method in laboratory.

Background information:

Salt or salinity is a biggest danger that causes reduction in crop productivity worldwide. Salinity reduces the germination percentage, plant vigour and ultimately loss in final crop yield. There are different physiological parameters that are affected by high level of salinity viz., oxidative stress, physical alteration of bio-membrane, nutritional imbalance, loss of cell division & cell expansion, water stress, genotoxicity and ion toxicity. Together, these effects reduce plant growth, development and survival. During the onset and development of salt stress within a plant, all the major processes such as photosynthesis, protein synthesis and energy and lipid metabolism are affected. During initial exposure to salinity, plants experience water stress, which in turn reduces leaf expansion (Petronia, et al. 2011).

The water-soluble compounds which, are low in molecular weight, accumulate at certain concentration known as “compatible solutes” or “osmolytes” is the common strategy adopted by many organisms to combat the abiotic stresses. Some common compatible solutes are betaines, sugars (mannitol, sorbitol and trehalose), polyols, polyamines and amino acid (proline). Their accumulation is favored under water-deficit or salt stress as they provide stress tolerance to cell without interfering cellular machinery. The tolerant or sensitive species show difference in the stress tolerance level based on levels of accumulation of these compounds during abiotic stress condition. Accumulation of osmolytes like glycinebetaine (GB) in cells is known to protect organisms against abiotic stresses via osmoregulation or osmoprotection. Other roles of GB like cellular macromolecule protection and ROS detoxification have been suggested as mechanisms responsible for abiotic stress tolerance. In addition, GB also influences expression of several endogenous genes in plants.

In sericulture it is the larval life that is of direct importance to the rearer since he has to take care of the worms very carefully. The larval life may last from 20-24 days in the case of the multivoltine species in tropical areas or 24-28 days in the case of uni- and bi-voltine races in temperate areas, being shorter under warmer summer and autumn conditions, and somewhat longer under cooler spring conditions. During the larval life the worm moults or casts off its skin four times to be able so as to grow. There are also varieties of worms which moult three and five times but they are not of importance economically. In view of the four intervening moults, the larval life is divided into five distinct stages or instars (Fig.14.2) which are referred to popularly as five different ages. The first three instars are referred to as young ages and the fourth and fifth instars as late ages.
14.2 Moulting
Each larval instar can be broadly divided into two phases i.e., the feeding phase and the moulting phase. After feeding voraciously and having attained full growth for the particular instar the worm loses its appetite and the larvaprepares to moult and cast off its old skin. Prior to each moulting, the larva  stops feeding and rests with its head held up. The lustrous body skin gradually becomes translucent, loose and wrinkled and the worm becomes dull in appearance and wanders about in search of a resting place. It emits a silky substance with which it fixes itself to dry leaves. The moulting periods last for 20 hours being shortest in the second moult, followed by the first, third and fourth. This resting for moulting is often referred to as going to sleep and the coming out of the worm from moult as waking up. During the moulting period the worms should not be disturbed so that the process of moulting is not interfered with and uniform moulting is ensured.

Abstract

Geochemical processes occurring within the groundwater and reactions with aquifer minerals have a profound effect on water quality. Hydrogeochemical composition of groundwater can also be indicative of its origin and history of passage through underground materials which water has been in contact. Assessing groundwater quality and developing strategies to protect aquifers from contamination are necessary aspects for proper planning and designing water resources. Anthropogenic activities like explosion of population, industrial growth, inputs of fertilizer, pesticides, and irrigation has been a crucial factor for determining the quality of groundwater. In this scenario, 43 groundwater samples were collected from the Dindigul district of Tamilnadu, a Hard rock terrain. The samples wereanalyzed for major cations and anions along with heavy metals to derive the different quality parameters and to obtain the pollution indices of different samples. This study focuses to find out the spatial relationship between the analyzed fluoride concentration in groundwater and pollution indices derived from the heavy metal concentration in the groundwater of the study area and their variation with respect to season.

Objectives

1. To know the botanical and other names of spices and condiments.
2. To identify the family, plant habit and plant part used of spices and condiments.

SOURCES OF LOSSES
In most of the cases of excessive fat or product loss, a combination of several factors rather than any single factor are responsible.
 
Inaccuracy in weighing: Receiving room scales should be checked regularly with a set of weights. The check should be made immediately before weighing operations begin. Improper drainage of the weighbowl will permit a carry over into the next batch dumped, resulting in incorrect weighing. Errors in weight in bulk handling methods may be caused also by improper leveling of the tank, incorrect calibration of the measuring rod, or carelessness on the part of the person taking the measurement.
 
Inaccuracy in sampling: Failure to collect representative samples may sometime cause sizeable losses. Milk should be properly agitated before taking samples. The composite sample should be preserved and refrigerated and should be protected from mould growth.

Abstract

A study on the Subsurface groundwater discharge (SGD) in the coastal Cuddalore region of south east India has been carried out. Measurement of surface water Radon, Water level, Electrical Conductivity (EC) and pH for a total of twenty four hours, by hourly interval the measurement has been calculated and promote correlated with tidal values calculated by WX Tide 32 software. The SGD measurements were made by using a modified seepage meter. The study reveals a match with water level variation and tide with minor variation due to influx of surface water. Saline discharges, fresh groundwater discharges and surface water mixing processes were identified along the coast. Lower SGD (37.24 – 79.16 cm/day) were observed during fresh groundwater discharge.

Objective

To study the salient features of important varieties of spices and condiments.

Objective: To identify agriculturally important insect orders and understand their key morphological characteristics relevant to their impact on agriculture.

Objective: To differentiate between locusts and grasshoppers based on their morphometric measurements and behavioral traits.

Concept of Ideotype breeding
In the breeding programme, elite crop varieties are developed through combination of relatively low-frequency alleles which are of known agronomic / horticultural importance (Lyu et al., 2013). During breeding programme, these elite varieties are developed targeting different main objectives, such as yield, product quality, resistance to abiotic and biotic stresses and agronomic suitability.
A crop ideotype is defined as an idealised structural model, combining both morphological and physiological traits, with the potential to maximise yield and quality within a defined environment (Donald, 1968). Ideotype generally include factors that increase the survivability of the plant such as drought resistance, resource use efficiency, root architecture and disease resistance (Arraiano et al., 2006; Rezzouk et al., 2022). Definition of “Ideotype” may be broadened through combination of morphological and physiological traits (or their genetic bases) conferring to satisfying adaptation of a crop to a particular biophysical environment, crop management and end use.

An ideotype is a crop plant having desirable morphological and physiological characteristics or both for cultivation in a specific agroclimate situation. An ideotype is constructed by the breeder on the basis of indepth study of morphological and physiological characters including their interrelationships, and intuition of the breeder based on his experience.

1.0. Objectives

• To illustrate the importance of using idioms in colloquial language
• To point out how idioms amplify the meaning of pieces of mind
• To make out how one can skip from a direct projection of ideas with the help of idioms
• To provide the knowledge of some significant idioms

2.0 Idiom

An idiom is an expression or articulation that generally presents an allegorical, different from its literal meaning appended to the phrases; however, a few phrases become metaphorical sayings while holding the strict importance of the literal expression. Sorted as predictable language, an idiom’s meaning is not quite the same as the imparting meaning. An idiom is an essential part of any language which shows the originality of language and its expression.

• Pathogen attacks the crop at all stages of crop growth.
• Symptoms appear on leaves, nodes, rachis, and glumes. On the leaves, the lesions appear as small bluish green flecks, which enlarge under moist weather to       form the characteristic spindle shaped spots with grey centre and dark brown margin (Leaf blast).

Introduction

In 2030, 289 MT of food grain production will be needed in India, whereas 349 MT would be needed in 2050. India's agriculture is now facing several problems, including the well-being of farmers, deteriorating soil health, stagnant productivity, a declining water table, soil salinity, a decline in factor productivity, and the need to limit further expansion of irrigated land. The livelihoods of millions of small farmers are in peril because of ecologically destructive and unsustainable agricultural practices. Growing countries must increase their agricultural production systems to boost their economies, food supplies, and food and nutritional security (Gill et al., 2005). Previous research initiatives in Indian agriculture that focused on a single company were inadequate to ensure sustained increases in production. Among the f inest choices for low-income farmers is the integrated agriculture system (IFS). With IFS, several farm operations may be streamlined to increase productivity and income. Agricultural waste and trash are also recycled on the property. It is essential that farmers have a reliable source of income if they want to raise their living standards beyond the poverty level. To deal with the challenges of the current economic, political, and technological environments, it is vital to progress production or consistently raise output.

Key Points

• Allergies are widespread among animals.

• Common allergens include food and drugs.

• Allergic reactions can occur through inhalation, skin contact, or eating.

• Housed cattle develop hypersensitivity pneumonitis, a persistent respiratory illness.

• Chronic exposure to spores in moldy, dusty hay is linked to the disease.

• There are two types of hypersensitivity: acute (also known as anaphylaxis or shock) and delayed.

Key Points

• Drug poisonings can be acute or chronic and result in the development of clinical signs and symptoms that may lead to animal disability or death, as well as extreme physiological and/or psychological changes.

• Drugs are substances that are used to prevent, treat, diagnose, and relive disease conditions by changing the physiology and/or psychology of the individual.

• Certain veterinary drugs have a specific antidote to counteract poisoning cases, while other veterinary drugs do not, and supportive therapy is required to counter these poisonings.

• Over-the-counter (OTC) medications, which are defined as human drugs or nutritional supplements that are available without a prescription, have potential risks for use in animals due to their increased toxicity.

Introduction

Many veterinary medications, which are used to treat both animals and birds, have the potential to poison the species to whom they are provided. These medications' toxic effects are mostly caused by giving them to the wrong species, at the wrong doses, or in the wrong combinations of medications. Certain medication poisonings can be identified due to patient individuality and eccentricities. As a result, there are many cases of these poisonings. This chapter discusses the poisoning caused by frequently and carelessly used veterinary medications, such as the toxicity of antibiotics and antibacterials, the toxicity of antiparasitic drugs, the toxicology of analgesics, the toxicity of cough treatments, the toxicity of the digestive system, the toxicity of vitamins, and the toxicity of topical preparations.

9.1 Plastering Storage area with Lime and Sand: The storage areas, known as Hagevu, are plastered with a mixture of lime and sand. These areas can store 20-30 bags of grain (Heggere and Chitradurga, Karnataka). Nagarathna (2000).

9.2 Indoor Bamboo or Reed Structure for Grain Storage: Indoor storage structures are typically made of bamboo. In regions where bamboo is scarce, farmers use locally available reeds. These structures are cost-effective since they utilize local materials and knowledge, but they do not protect grains from rodents and insects, have a short lifespan, are susceptible to fire, and require frequent maintenance (Andhra Pradesh and Orissa). Navanitha Raju (1999).

9.3 Storage of Onion Bulbs on Bamboo Platform: Onion bulbs can be stored for up to a year on a platform made of loosely woven bamboo strips, raised 2-3 feet above the ground to allow air circulation. The bulbs are piled 2-3 feet high and protected from sun and rain with a cover (Junagadh, Gujarat). Babulbhai (1993).

9.4 Method of Storage of Food Grains in Khanti: A 'Khanti' is constructed in areas with low underground water levels, where a 15-foot deep Khanti can be made. It has a sloping shape with a base 10-15 meters wide and a top one foot wide. A one-foot thick layer of husk mixed with neem is spread at the bottom and sides for pest protection. Different grains can be stored by separating them with layers of husk and large leaves. A Khanti can store 10-15 tonnes of grains from May to November (Maharashtra). Singh (1999).

9.5 Storage of Potato Tubers: Farmers in Hoskote village, Karnataka, store potato tubers in the field on an elevated, hardened soil area of 25 × 4 square feet, supported by 12 stone pillars. A thatched roof provides shade, and a bed of local grass and sugarcane leaves is spread on the floor. Harvested tubers are layered on this bed, with additional layers of leaves on top. The storage is checked for pests every 2-3 weeks. Calotropis gigantea leaves and branches are used around the heap to prevent rodent attacks. This method keeps potatoes cool even in hot conditions (Bangalore, Karnataka). Hannganahalli (1999).

10.1 Multiple transplanting for increasing papaya yield: Papaya seedlings are uprooted and transplanted at a different spot, then uprooted again and planted back at the same spot after fifteen days. This decreases the plant's height and enhances its productive phase (Banaskantha, Gujarat). Kodarbhai (1999).

10.2 Reducing mango flower drop by applying buttermilk and salt: To prevent mango flowers from dropping due to wind and disease, farmers dig a circular trench around the tree trunk during flowering, mix 60-80 liters of buttermilk with 2 kg of salt, and pour it into the trench. After absorption, fresh water is added, and the practice is repeated (Banaskantha, Gujarat). Dudhaji (1997).

10.3 Enhancing fruit set in papaya by inserting a nail in the stem: To induce fruiting in trees that flower but do not bear fruit, farmers insert nails (iron or wooden, 1-2 cm in diameter) into the stem about a foot high (Amreli, Gujarat). Sheldiya (1992).

10.4 Increasing yield of vegetables and fruits by using hair: Waste hair is collected and applied to vegetable, fruit, and ornamental crops. Hair is buried around plants in pits (1/2 kg for ornamental plants, 1 kg for fruit trees) one month after planting and 45 days before fruiting. For vegetables like tomato and brinjal, hair is dispersed during the last ploughing (Tamil Nadu). Subbiah (1998).

10.5 Lemon juice for higher lemon productivity: Farmers increase lemon productivity by spraying a solution of 100 ml lemon juice dissolved in 2 liters of water on lemon trees, ensuring all leaves are wet (Rajkot, Gujarat). Pethan (1997a).

IKS stands for Indigenous Knowledge Systems. When applied to pest and disease management in agriculture, IKS refers to the traditional and local knowledge systems developed by communities over generations to deal with agricultural challenges, including pests and diseases.

5.1 Key Aspects of IKS for Pest and Disease Management

1. Traditional Practices: Indigenous communities often have developed practices based on observation and experience to control pests and diseases. These may include specific plant combinations, crop rotations, or timing of planting to minimize pest damage.

2. Natural Remedies: IKS often includes knowledge of natural substances and plants that have pesticidal or medicinal properties. Examples include the use of neem, garlic, chilli, or certain plant extracts to deter pests or control diseases.

3. Cultural Practices: Traditional farming practices may include rituals or timing of activities that are believed to influence pest and disease outbreaks. For instance, planting during specific lunar phases or following certain cultural calendars.

4. Biological Control: Indigenous knowledge may also involve the use of natural enemies of pests, such as predators or parasites, to manage pest populations. This aligns with modern biological control principles.

5. Crop Diversity: Traditional farming systems often promote crop diversity, which can help naturally manage pest and disease pressures by reducing monoculture effects and providing habitats for beneficial organisms.

Seed treatment refers to the application of chemical or biological substances to seeds before planting. This process is designed to protect seeds from diseases, pests, and other adverse conditions that may affect germination and early growth and can improve overall crop yield and quality. Seed treatment can involve the use of fungicides, insecticides, bactericides, and other agents that help improve seed health and vigor. Seed treatment is a crucial step in ensuring healthy crop production. By investing in seed treatment, farmers can achieve better crop establishment and reduce the need for subsequent interventions, leading to more sustainable and cost-effective agricultural practices.

4.1 Importance of Seed Treatment

1. Disease Control: Seed treatment helps to protect seeds and seedlings from soil-borne and seed-borne pathogens, reducing the risk of diseases that can impair seed germination and seedling growth.

2. Pest Protection: Treated seeds are less likely to be damaged by insects and other pests that may be present in the soil. This protection can lead to higher seed survival rates and better crop establishment.

3. Improved Germination: By reducing the incidence of diseases and pests, seed treatment can enhance the germination rate and uniformity of seedlings, leading to more robust and consistent crop stands.

4. Nutrient Provision: Some seed treatments include nutrients or growth promoters that help improve seedling vigor and early development, ensuring that young plants have a better start.

5. Resistance to Environmental Stress: Seed treatments can help seeds withstand adverse environmental conditions such as drought, salinity, and temperature fluctuations, improving the overall resilience of the crop.

A decoration, interpretation, or visual explanation of a text, concept, or process that is intended to be included in published media including posters, flyers, magazines, books, teaching materials, animations, video games, and films is called an illustration.

Using Illustrations

We can comprehend information better when it is shown. Illustrations were one of our first forms of communication, long before any kind of contemporary writing. In reality, new discoveries of cave drawings from more than 35,000 years ago show that humanity have been using images to communicate for a very long time. This did not occur by accident; according to study, over 90% of the information we process is visual, and a significant portion of our brain is dedicated to visual processing.

Benefits of using Illustrations

The sensors present over remote sensing satellites are designed to collect energy or radiance from the varied surface features having wide range of radiance i.e. from features like water bodies having very low radiance to features like sand or snow having very high radiance. But, most of the time, the study area may not have all these features; therefore, radiance values may remain confined to a narrow range. This reduces the contrast of the image, thereby decreases its visual quality. In this context, image contrast enhancement techniques are used for effective visualization and display of remote sensing image on computer screens or hard copy so that maximum amount of information can be derived through its visual interpretation.

Contrast enhancement of a digital image is a technique to modify the original grey levels of input image to the entire available range of the grey levels. This increases the contrast between various features in the image which improves the visual quality of original image. Contrast enhancement can be done by both linear and non-linear methods. Some of the commonly used contrast enhancement techniques with their implementation in R software are discussed in this chapter.

We need following packages for performing this exercise in R. raster package is required for importing of raster image and for performing contrast enhancement. RStoolbox package is also required for contrast enhancement as well as for visualization of raster data with ggplot2 package. rasterVis package is mainly used in this exercise for plotting histogram of the raster data.

The information of image is perfectly accepted by eyes when the image will be in convenient form. Always pictures accurately detail about information related to their position, sizes and inter-related with each other is objects. Actually images portray positional information which can be recognized as objects. Human eyes are exact example for differentiating that information from images to innate visual and mental ability.

Abstract

Before 1960’s, UAE was a poor developing country and almost there were no real signs of civilization. During the 1970’s two important things happened: H. H. Sheikh Zayed Bin Sultan Al Nahyan, the president of UAE, and the other Emirates rulers united together and established the United Arab Emirates and considerable oil findings were discovered. The UAE Leadership has proved to have deep future vision; in three decades the country jumped from a relatively backward scattered emirates to a well developed and civilized country.

Development is very obvious : from tents and sandy tracks to tower buildings and highways, from desert to green belts of palm trees and vegetables in all parts of the country, and most important, education, healthcare and all other services became the best in the region. Urban development was so sharp; someone who left the place 10 years ago can hardly know his location and services in all sectors became the best at the international level. The oil money was properly invested in development.

UAE Air Force Space Reconnaissance, used satellite and aerial images for the past 20 years and successfully utilized images from various sources including aerial photographs, Russian satellites images, SPOT and Landsat

19.1 Introduction

Nano technology or Nano Science is a new branch of research though nano materials or Nano Structures are not new. In nature nano particles or nano materials are abundant .The idea of manipulation, production, controlling size and physico - chemical properties and application as well as making devices out of these nano materials is the subject of Nano Science & Nano Technology. As the name suggests, the domain of Nano starts from 10-9 m but especially the effect of nano structures exists mostly in the 1-100 nm regime where quantum - mechanical behiviour is prevalent. Molecules with more than 10 atoms fall into the nanometer range  and scientists were not able to visualize individual molecules and nano scale objects until the invention of some very powerful microscopes. Working in Nano domain requires two basic facilities -

Almost all imaging techniques employed in human medicine are being followed in canine medicine but radiography and ultrasonography ( abdominal and cardiac) are the most commonly used clinical diagnostic techniques. Computed tomography, magnetic resonance imaging, and nuclear techniques are also being used in the teaching establishments.

Radiography

Use of radiography (Figure 42) as a diagnostic technique is wide spread in canine and feline medicine across the world. It is considered the first step in evaluating the skeleton, thorax and abdomen. For evaluating the abdomen, radiography is considered as complimentary to sonography. Canine practice is more like pediatrics requiring assistant to control the patients (dog sand cats). No anesthesia or sedation is generally required for radiography. But if the patient has painful lesion such as fracture or luxation, suitable anesthesia / sedation should be used for making the animal cooperative during radiography for better visualization of the lesions.

IMF : Short for International Monetary Fund, referee and, when the need arises, rescuer of the world’s financial system. The IMF was set up in 1944 at bretton woods, along with the world bank, to supervise the newly established fixed exchange rate system. After this fell apart in 1971–73, the IMF became more involved with its member countries’ economic policies, doling out advice on fiscal policy and monetary policy as well as microeconomic changes such as privatisation, of which it became a forceful advocate. In the 1980s, it played a leading part in sorting out the problems of developing countries’ mounting debt. More recently, it has several times co-ordinated and helped to finance assistance to countries with a currency crisis.

Immunity, active : Resistance developed in response to stimulus by an antigen (infecting agent or vaccine) and usually characterized by the presence of antibody produced by the host.

Immunity, herd : The resistance of a group to invasion and spread of an infectious agent, based on the resistance to infection of a high proportion of individual members of the group. The resistance is a product of the number susceptible and the probability that those who are susceptible will come into contact with an infected person.

Immunity, passive : Immunity conferred by an antibody produced in another host and acquired naturally by an infant from its mother or artificially by administration of an antibody-containing preparation (antiserum or immune globulin).

Defination

Dislocation of carpometarcarpus and tarso metatauses along with upper fracture of MC and MT bone (Fig. 1 and Fig.2). It is considered as difficult fracture and may not be healed appropriately by the usual procedure of lower level fracture repair method. Due to constant movement of fracture ends its treatment should be similar to middle level fracture repair method.

Materials Required

Thick padded cloth

Adhesive gum (fevicol)

Netted bamboo splint

Thomas splint

Purpose

As the immobilisation of upper third part of radius ulna is very difficult ,the purpose of the immobilisation tech. Is to fix the upper third of radius-ulna with the posterior half of ring of Thomas splint with bandages are very important for achieving no movement of fracture fragment during healing.

Indication

Correction of upper third fracture of radius-ulna by Thomas splint application indicated in higher level fracture.

Objectives

Immobilization of fracture of mandible.

Requirements

‘U’ Plate 4 Pins Electric drill Orthopaedic hammer Pin cutter

Procedure

Under local infiltration of an anesthetic & parenteral sedatives the 4 pins are drilled 2 on either side of the fracture site from one side mandible to other side mandible. During drilling the pin, the holes, importance should be given for the passage of the pin through prefix of the drill hole in metal frame

The fracture end should come accurate apposition during pinning procedure & the symmetry of the fractured mandible should be as norma! as possible.

Sterilised antiseptic gauge bandages are covered, the pin between frame and the body. The pins are retained in position either with nut-bolt or by passing a plastic tube after which the hole of the plastic tube is filled with resin.

To know the method of immobilization of the limb after repair of the transected gastrocnemius tendon (tendo achiles).

Procedure

The immobilization procedure of limb after gastrocnemius tendon repair is done in 2 stages.

1^ST Stage

Immobilization of limb for avoiding movement at tendon suture site.

It is done by placing the sutured area within a pre- fabricated metal frame so as to keep the limb undisturbed at the suture site.

The frame is given in Figure 1.

The purpose of addition of the metal frame is to immobilize the limb keeping the fetlock and foot away from in a flexed manner to avoid weight bearing during healing period.

The limb is immobilized with netted bamboo splint (Fig. 2).

The immobilized limb is placed within the metal frame keeping the fetlock and foot in a flexed manner

Aim: To know the method of immobilization of the limb after repair of the flexor tendon.

Procedure

The immobilization procedure of limb after flexor tendon repair is done in 2 stages.

Definition: Mandible forms the skeleton of lower jaw and comprises of a body and two rami. The two halves of this bone fuse incompletely at the mandibular symphysis, situated at the midline within the body.

Indication: Immobilization of fractured mandible, minimally or non displaced fractures with an intact opposite hemimandible, vertical ramus fracture.

Anasthesia: Local anaesthesia for large animals. A20 gauze 2.5 cm needle is used to deposit 5-1 Omi of lidocaine at the exit site and into the canal.

Infection refers to the invasion of harmful microorganisms into the body and causing disease. The most important function of the immune system is to protect the body of the host against various viruses, bacteria, fungi and parasites. The grounds of immune surveillance stand on the basis of innate and specific immunity that build up against the evasive mechanisms of the disease causing organisms. Infectious disease is result of a complex interaction between  the host and the microbes. Evasions of protective immunity by the parasites critically determine the survival and pathogenicity of the microbes. The invasion of the body by harmful microorganisms is called infection. Infections are dangerous in any part of the body. Microorganisms spread vary easily into the blood stream and cause blood poisoning which is called septicemia.
