The value addition results in more acceptable quality products for the domestic and export market and hence ensure high premium to the producers. Moreover, value addition technology can help avoiding wastage during the glut period and farmers involved in the flower cultivation can earn better remuneration. Preparation of value added products helps in employment generation at producer level, wholesaler level or industrial level. It is a good source of income generation. There are various types of value added products which can be prepared either by practice or by obtaining training of making these products. The value added products can be classified into three categories namely:

1. This is fragrant rose variety

   a) Blue Moon

   b) First Red

   c) Gladiator

   d) None

2. Rose belong to family

   a) Amaryllidaceae

   b) Compositae

   c) Rosaceae

   d) None

1. GENERAL FLORICULTURE

Development of Floriculture’ was recommended by Dr. P.P. Trivedi committee.

India ranks 2^nd in flower cultivation next to China.

The production of loose flowers almost tripled between the 8^th Plan and the 11^th Plan.

The annual domestic demand is valued at around 60 billion USD.

About 2,33,000 hectares across the country was used for floriculture, producing 17,29,000 metric tonnes (MT) of loose flowers and 76,732 lakh cut flowers.

India has exported 22,947.23 MT of floriculture products to the world for worth of Rs. 460.75 crores in 2014-15.

The share of exports of dried flowers and plant parts are 45%, flowering plants (22%), fresh foliage (13%), fresh cut flowers (10%), live plants (7%) and bulbs and tubers (3%).

India’s share in global floriculture trade- 0.6%.

USA ranks 17th in per capita cut flowers consumption.

India ranks 2nd in flower cultivation next to China.

India stands 14th in the world in exporting floricultural products, while the Netherlands and Columbia rank 1st and 2nd, respectively

Those plants which are completed their life cycle in a season or a year, is called annuals. Thre are many types of annuals.

1. On the basis of seasons:
   1. Rainy annuals: Balsam, Cock’s comb, Amaranths, Gaillardia, Torenia, Gompherena etc.
   2. Summer annuals: Zinnia, Kochia, Tithonia, Sunflower, Cosmos, Coreopsis.
   3. Winter annuals: Remaining annuals.

The scientific horticulture consists of the following divisions. Among them, which division has impact on environment aesthetically and functionally

A. Fruits         B. Flowers

C. Spices       D. Plantations

World Trade Organization (WTO) is an international body which deals with the “Rules of Trade” between nations on the basis of the agreements negotiated and signed by most of the world’s trading nations. These agreements are essentially contracts that bind governments to keep their trade policies within predefined limits. The goal is to help producers of goods and services, exporters and importers.

The purpose of WTO agreement is to help free flow of trade, serve as a forum for trade negotiations and to serve as a dispute settlement body. There are 5 broad principles of the trading system followed under WTO:

Trade without discrimination

Freer trade, gradually through negotiations

Predictability, through binding

Promotion of fair competition

Encouragement to development and economic reforms.

Introduction

Floriculture or flower farming is the study of growing and marketing flowers and foliage plants. Floriculture includes cultivation of flowering and ornamental plants for direct sale or for use as raw materials in cosmetic and perfume industry and in the pharmaceutical sector. It also includes production of planting materials through seeds, cuttings, budding and grafting. In simpler terms floriculture can be defined as the art and knowledge of growing flowers to perfection. The persons associated with this field are called floriculturists.

Worldwide more than 140 countries are involved in commercial Floriculture. The leading flower producing country in the world is Netherlands and Germany is the biggest importer of flowers. Countries involved in the import of flowers are Netherlands, Germany, France, Italy and Japan while those involved in export are Colombia, Israel, Spain and Kenya. USA and Japan continue to be the highest consumers.

Floriculture  is  increasingly  regarded  as  a  viable  diversification  from traditional field crops due to increased per unit returns and increasing habit of “saying it with flowers” during all the occasions. All over the world, the floricultural sector is experiencing rapid changes. Opening up to the world, market  in  the  WTO  regime  paving  way  to  free  movement  of  floricultural products worldwide, globalization and its effect on income generation have all  contributed  to  increase  in  per  capita  consumption  of  flowers  in  most countries. Noticeable  feature  of  global  floriculture  is  the  development  and expansion of floriculture in non-traditional areas. Netherlands, Italy, Germany and  Japan  had  strong  tradition  for  growing  and  consumption  of  flowers. The  concept  of  commercial  floriculture  was perpetuated  across  the  world from those regions. New production centres are developing in Latin America, Africa and also in Asia to meet the demand of consuming countries and also to  expand  domestic  market,  commensuration  with  improved  economic conditions  these countries  provide  highly  qualitative  floricultural  products with low cost price which is finding a favourable place in markets of Western Europe, America and Japan. Emergence of new production centres has made floriculture  more  competitive  and  this  in  turn  is benefiting the  ultimate consumers.

Introduction

Floriculture, the branch of horticulture dedicated to the cultivation of flowers and ornamental plants, has gained significant attention and importance due to its multifaceted prospects and scope. It is a captivating blend of art and science, encompassing the nurturing of plants for aesthetic, commercial and even therapeutic reasons. From the meticulous care of delicate blooms to the strategic planning of vast floral displays, floriculture spans a wide spectrum of activities, each contributing to the beauty and functionality of our surroundings. From the meticulous care of delicate blooms to the strategic planning of vast floral displays, floriculture spans a wide spectrum of activities, each contributing to the beauty and functionality of our surroundings. This can range from the production of cut flowers for floral arrangements and bouquets to the cultivation of potted plants for indoor decoration. Whether it’s the striking colors of roses, the delicate petals of orchids, or the lush foliage of ferns, floriculture celebrates the diversity and splendor of the plant kingdom.

Floriculture is the aesthetic branch of horticulture which deals not only with the cultivation of ornamentals, annuals, biennials and perennial plants but also with their marketing. Flowers symbolize beauty, purity, peace and love. In India, it is a dynamic and expanding industry showing an impressive annual growth rate.

Classification of Flower Crops

The flowering plants can be classified broadly on the basis of their species, genus, family, plant part used or type of flower plants. They are further classified as cutflowers, cut foliage, turfgrasses, groundcovers, hedges, accents, specimen plants, avenue trees, screens, topiaries, fillers and others.

Important Points to Remember

ROSE

• Botanical name: Rosa spp.
• Family: Rosaceae
• 2n = 14
• Origin: North Hemisphere (Himalyas)
• Flower colour: Red (commonly)

12.1 Meaning and Definition

A flow chart is a graphical or symbolic representation of a process. Each step in the process is represented by a different symbol and contains a short description of the process step. The flow chart symbols are linked together with arrows showing the process flow direction. This diagrammatic representation can give a step-by-step solution to a given problem. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields.

7.1 Determination of Hydraulic Conductivity of Saturated Soil Laboratory Methods

Hydraulic conductivity of a saturated soil indicates the ease with which water is transmitted through the soil pores. If a constant water head (h) is maintained on a saturated soil column of length (L) and the volume of water (V) percolating per unit time (t) through per unit cross sectional area (A) to the other end, then according to Darcy’s Law, the rate of flow of liquid or flux (q) is proportional to the hydraulic gradient (ÄH/L) across the length of soil column.

Flower arrangement is the art of using plant materials and flowers to create an eyecatching and balanced composition or display. Among all art forms, flower arrangements today take as prominent a place. The art engages ones personal involvement in welcoming guests and bringing cheer to the surroundings. It is rightly said, “Flowers are the music of the ground. From earth’s lips spoken without sound. “Professionally designed floral designs, arrangements or artwork incorporate the elements of floral design: line, form, space, texture, and color, and the principles of floral design: balance, proportion, rhythm, contrast, harmony, and unity.

Composition of Arrangements

There are a few compositions of flower arranging that should be considered. Once we understand these we can create so many different styles and our floral designs will have that professional look.

Ikebana

Flowers are generally known as the symbol of beauty around the world. Many people stick flowers in vases to wreath their rooms, houses and other places. Japanese FlowerArrangement is essentially different from the Western style of flower arrangement. The western style involves symmetrical arrangement of flowering plants in a vase whereas, the Ikebana, which means “flowers kept alive”, is much more intricate, complex and asymmetric. This style of flower arrangement is one of the famous cultural traditions of Japan known around the world. Generally, all Japanese flower arrangement styles are lumped together as ikebana but we cannot say they are all the same. Ikebana is a disciplined art form in which nature and humanity are brought together. Though it is a creative expression, it has certain rules governing its form. The main rule is that all the elements used in construction must be organic, be they branches, leaves, grasses, or flowers. The artist’s intention behind each arrangement is shown through a piece’s colour combinations, natural shapes, graceful lines and the usually implied meaning of the arrangement. They arrange flowers to recreate nature in miniature to see individual flowers which have been left behind. Ikebana is like one of the ways to communicate with nature. Another aspect present in ikebana is its employment of minimalism. That is, an arrangement may consist of only a minimal number of blooms interspersed among stalks and leaves. The structure of a Japanese flower arrangement is based on a scalene triangle delineated by three main points, usually twigs, considered in some schools to symbolize heaven, earth and man and in others sun, moon, love & earth. The container is also a key element of the composition and various styles of pottery may be used in their construction. Over time, the ways and styles have changed but there is still the basic idea of ikebana remain same.

Definition: Flower arrangement may be defined as the art of organizing and grouping together flowers and plant materials to achieve harmony of form, colour and texture.

Types of flower arrangements

A. Japanese or oriental/eastern type: Japanese flower arrangements also called ‘Ikebana’ (Ikebana, also called Kado). Emphasis is given on spiritual and religious background and only few flowers are used. “Ikenabo” was the first school of Ikebana, meaning “the arrangement of flowers of the hermitage along a pond” which was started by Buddhist monk Semmu around A.D. 621. Ikebana was practiced by Buddhist monks as a concentration exercise (Dhyana). There are three basic lines that were followed in Ikebana namely, Shin meaning heaven is generally a central vertical line of the main branch in the arrangement. Whereas, Soe meaning man is the secondary branch symbolizes human kind. Ikebana artists position Soe to grow forward from the Shin line at a right angle. Third is, Hikae, symbolizes earth is arranged at the bottom, opposite the first two elements. In India, Ikebana was introduced during sixties and gradually becomes popular.

Flowers of the garden are brought indoors to enjoy the beauty. Fresh flowers are arranged in various styles according to one’s choice. There are two major and distinct styles of arranging fresh flowers, namely the European and the Japanese. Both the styles are greatly influenced by the place where they have been originated. Flowers are also dried and used for different arrangements. Fresh flowers are used as ornaments and also for making floral patterns on the floor called Rangoli.

1. INTRODUCTION AND IMPORTANCE

Flower arrangement is a very old art. In India, the flowers have been earlier arranged in temples and during festivities. The first rules of ikebana were laid down in Japan more than a thousand years ago. Flowers have been widely used for interior decoration, but they were cut from the garden and simply massed into water-filled containers to brighten the home. The beauty of the display relied upon the blooms themselves rather than the aesthetic appeal of the design. Even at homes and venues of festivals/functions/on auspicious occasions, flowers are used in a big way in the form of garlands, wall hangings, and floor decorations. Flower arrangements grace table tops, window sills, corners, fire places, and so on to suit the occasion.

Flower arrangement may be defined as the art of organizing and grouping together plant materials (flowers, foliage, fruits, twigs etc) to achieve harmony of form, colour and texture, thereby adding cheer, life and beauty to the surroundings.

Various types of arrangements are chosen, as appropriate to the area and occasion. Medium sized ‘round’ arrangements are often provided at the guest relations executives’ desk in the lobby and on coffee tables in the lounges. In most five-star hotels, one can see huge, spectacular arrangements in the loggies. Table arrangements for conferences must be low so that guests may see over them. At informal banquets, large arrangements may be seen. At wedding banquets, wall arrangements using gerberas are very popular, now a days. On special occasions and festivals, a large amount of flowers is required for making up various types of arrangements. The extent to which flowers are used in hotel interiors depends on the degree of luxury provided, the number of special functions held.

The housekeeper is responsible for all flower arrangements and their placement. Simple arrangements such as a bud in a vase can be done. Alternatively, flower arrangements may be provided on contract, in which case the arrangements are brought in and taken away at agreed times and little or no floral work is carried out on the premises. Arrangements like running water, containers, buckets, vases, scissors and flower pots are important.

Introduction

Flowers are the most fascinating objects in the world and many poems are written glorifying them. They are associated with mankind from the dawn of civilization. Flowers are an integral part of our day to day life and they find a place in worshiping, religious and social functions, wedding, interior decoration and self adornment. Flowers are used to convey the human feelings. To say it with flowers is very common in western culture. Emergence of a strong middle class and changing life style has created a great demand for cut flowers in India.

Introduction

Pomegranate (Punica granatum L.) is an important fruit crop of hot arid region of the India. It is grown commercially in the states of Maharashtra, Gujarat, Karnataka, Andhra Pradesh, Tamil Nadu, Madhya Pradesh and Rajasthan. India is one of the largest producers of pomegranate in the world. The pomegranate area in arid region is increasing at faster rate due to its incessant demand, drought hardy nature, low cost management and wider adaptability to arid soils. In Rajasthan it is mainly grown in Jaipur, Ajmer, Alwar, Tonk, Sriganganagar, Tonk, Pali, Kota, Jalore, Banswara, Sawai Madhopur, Bhilwara, Jhunjhunu and Sirohi districts in 12,000 ha area (Rathi, 2017). The pomegranate plants flower and provide fruits throughout the year. In Rajasthan pomegranate is harvested in all three seasons during March-April, Aug.-Sep. and Nov.-Dec. However, it needs to be forced into rest period for prolific harvest at a given time. The basic objectives of flower regulation in pomegranate is to manipulate the natural flowering and fruiting in such a way that it produce high yield of quality fruits in desired season with sustainable use of farm resources. Transition of flower from vegetative phase to reproductive phase is critical phase in pomegranate flowering, which determine production efficiency. The differentiations of vegetative tissue to reproductive tissue decide flowering intensity and production efficiency. Withholding of irrigation (moisture stress), plant growth substances, nutrient content along with canopy management are major horticultural interventions for flower regulation which influence flowering. It is based on principles that pomegranate bears three kinds of flowers namely hermaphrodite, intermediate and male flowers (Fig.1) on both new and old growth in three flushes i.e. ambe bahar (Feb.-March), mrig bahar (June-July) and hasta bahar (Sep.-Oct.).

INTRODUCTION

Seed is one of the most vital and important inputs for increasing agricultural production. Commercial flower seed production is an international business involving highly specialized growers. Compared with the production of seeds of cereals, pulses oilseed even vegetable seeds, it is done on a relatively small scale. However, a large number of species are being produced under very different cultural conditions. It seems to have great scope for expansion in developing countries like India, especially under northern India climatic zones having favourable growing conditions, skilled and cheap labour.

Seed is one of the most vital and important inputs for increasing agricultural production. Commercial flower seed production is an international business involving highly specialized growers. Compared with the production of seeds of cereals, pulses oilseed even vegetable seeds, it is done on a relatively small scale. However, a large number of species are being produced under very different cultural conditions. It seems to have great scope for expansion in developing countries like India, especially under northern India climatic zones having favourable growing conditions, skilled and cheap labour.

Annual flowers like petunia, coreopsis, helichrysum, phlox, nasturtium, marigold, gaillardia, salvia, ice plant, verbena, nemesia, pansy, poppy, larkspur, chrysanthemum, etc. have been widely used for seed production. After release of a variety its seed have to be multiplied in sufficient quantity which takes 3-4 generations before it reaches to the farmers for commercial use. The Indian seed programme largely adheres to the limited generations system for seed multiplication in a phased manner. The system recognizes three generations namely breeder, foundation and certified seeds and during multiplication cycle care has to be taken so that variety does not degenerate but maintains its original characteristics.

Seed production of flower has undergone unrestricted revolutionary growth in term of number of crops and their varieties as well as production. This phenomenal development is the result of technological advancement in the production of flower seed and development in the area of production, packaging, handling, transportation and marketing of flower and ornamental plants all over the world. The world germplasm contains more than 1500 different varieties of flowers and ornamental crops. Each species of flower grown for seed has its own specific time, culture, problem of pollination and harvesting and storage requirements. Mild climate with moderate rainfall favour the growth and development of most flower and ornamental crops.

Production of seeds of annual flower is having immense impetus as regards the diversification in floribusiness. The flower seed industry is truly international, operating in many countries in the world. Large quantities of annual flower seeds are required both by developed and developing countries adding to the beauty of private and large gardens and also for cut flower production. Annual flower are indispensable in respect of beautification of gardens. In the world, many nurseries are engaged in the production of seed of seasonal flowers and are having a blooming business. The great diversity of flower seed crops is fascinating facet of the world seed industry and they are of high value and low volume in contrast to the high volume and low value seeds. The varied agroclimatic condition existing in India provides a vast scope for the production of a wide range of flower seeds of both tropical and temperate origin. With the availability of relatively inexpensive human labour, technical expertise, and other material, it is possible to organize a strong flower seed production programmed exclusively for export purpose.

Seed is defined as “Fertilized and ripened ovule, consisting of the plant embryo, varying amounts of stored food material and a protective outer seed coat”. It is one of the most vital and important inputs for increasing production of crops. Commercial flower seed production is an international business involving highly specialized growers. Demand of flower seed production increased due to recent advances in commercial production of bedding plants, plug production technology, increased area of gardening, flower growing in home gardens and cut flowers with highly viable seeds and very high percentage of uniform seedlings. It seems to have great scope for expansion in developing countries like India, especially under north Indian climate having favourable growing conditions, skilled and cheap labour.

The world germplasm contains more than 1500 different varieties of flowers and ornamental crops. Each species of flower grown for seed has its own specific time, culture, problem of pollination and harvesting and storage requirements. Growing flower from seed is an important component of commercial flower production and their uses in landscape gardening.

1. CUT FLOWERS

1.1. Common name, scientific name and family

Definition: It is an event at which flowers are displayed and judged for awards.

Flower shows help to spread the world about the joys of gardening and serve as forums for learning and discussing the latest horticultural and design trends. Such flower show offers a wide variety of helpful resources for those interested in learning more about growing flowers for exhibition, designing floral arrangements or exhibiting plants. In addition, many national level flower shows offers training opportunities for members who are interested in becoming certified flower show judges. A Preliminary spadework has to be done to make a show successful. Success depends upon the co-operation between the exhibitor and the members of the flower show committee.

H erbs include non-woody or succulent-stemmed plants that are relatively shorter in stature when compared to shrubs. Based on their ornamental nature they can be broadly grouped as Flowering Herbs and Foliage Herbs. Flowering Herbs can be further classified based on their duration into Annual Flowering Herbs and Perennial Flowering Herbs. Foliage herbs of a perennial nature are further differentiated into monocotyledonous and dicotyledonous foliage herbs.

ANNUAL FLOWERING HERBS

Annual herbs are grown in gardens for their spectacular beauty when they are in flower. They are seasonal in habit and have duration of up to four months. Most of them have a short vegetative phase, which is followed by continuous flowering for several weeks. They are used in gardens for obtaining various colour effects. Varieties of annuals having analogous or similar flower colours can be grouped in flowerbeds and flower borders for monochromatic effects. For contrasting colour effects, varieties having complementary or contrasting colours like violet and yellow or blue and orange as well as green and red can be used. For colour blending effects, flowers having different shades of the same colour can be grown.

1. FLOWERING

The flowering goes through a phase of vegetative growth producing more stems and leaves and a flowering phase where they produce the organs for sexual reproduction.

1.1. Synchronisation in flowering

Synchronous flowering refers to the phenomenon of coincident, simultaneous flowering of all population of a given species in a large region.

Floriculture is the most important aspect of urban agriculture, which fulfils the need for beautification, recreation, entertainment and income earning. In broader sense, it includes growing flowering and ornamental plants in gardens, rooftops and terraces. Floriculture comprises of house plants, flowering plants, pot plants, cut flowers and decorative foliage. It also deals with cultivation of cacti, orchids, succulents, bonsai, ferns and plants grown in landscape gardening.

Role of flowers in our life

• It is a unique gift of nature to relax human mind
• The fragrance and beauty of flowers bring joy and happiness
• Flowers are used as a symbol of grace and sophistication
• Flowers are used in religious rituals for offering during worship

Flowsheet

Based on various experimentations concerning live fish transportation, a flow sheet may be prepared as:

Evaluation of the health status of the fishes purchased from the market to be packed for transportation. Serrated operculum and spiny fins, if any (as in Anabas testudineus) is serrated as it damages the packing materials. The trimmed fishes are treated with antibiotics and left for a week for wound healing.

In the case of abroad transportation of fish, clearance to the fitness of fishes is made available from a veterinary doctor/inspector. A no-objection certificate is also obtained from the office of the Marine Products Export Organization.

Proper sanitization of all the equipment and accessories for the determination of oxygen uptake of fishes as well as all the other steps of fish transportation in this pandemic of COVID-19.

Determination of oxygen requirement of the fish in terms of per hour and per unit body weight is essential. In the case of air-breathing fishes to be packed (Like Channa punctatus, Anabas testudineus, Clarias batrachus and Heteropneustes fossilis), determination of aerial and aquatic oxygen requirement of the fishes is essential. The oxygen requirement of oxygen was estimated from the calculated values of intercept (=a) and slope (=b). For this calculation, a relationship of aW^b is applied.

A large proportion of the body of mammals including domestic animals, is made up of water. This water is an essential attribute for the life of the animals. Animals deprived of food but provided water will survive much longer than the animals provided with food but deprived of water. Water is the basis of the liquid environment of the cells, which Claude Bernard called the milieu interieur, and Cannon the fluid matrix.

1. Introduction

Movement of fluids from one location to another is an important unit operation in food processing. Various types of systems are used to convey fluids based on their flow behaviour. Understanding fluid flow behaviour is therefore important for designing of fluid flow systems. The fundamental mechanism involved in fluid flow is the momentum transfer occurring in moving fluids during various unit operations (fluid flow, aeration, drying, fluidization, filtration, centrifugation, sedimentation, mixing, etc.). This chapter deals with the basic concepts of fluid flow, viscosity, pressure measurement, conservation of mass and energy, boundary layer, momentum and velocity profile of fluid flowing in a pipe, flow metering devices, and pumps.

Q. 1 Density of water is:-
(A) 1000 kg/m3    (B) 500 kg/m3
(C) 1500 kg/m3    (D) 2000 kg/m3

Technical Term           Definition

Fluid Mechanics         Fluid Mechanics is a study of physical behavior of fluids and fluid systems, and laws governing their behavior. It incorporates action of forces

                                   on fluids and the resulting flow pattern

There is a delicate balance among electrolyte concentrations, body water and acid base status to maintain body homeostasis. Disturbances in homeostasis results in life threatening abnormalities. The aim of fluid therapy is to replace losses and maintain fluid and electrolyte balance in the body.

Fluid therapy is a critical intervention in Veterinary Medicine, requiring careful assessment and monitoring to ensure effectiveness and to minimize risks. Tailor made individualized approach is essential for optimal outcome. Fluid Therapy in Small Animals Indications •     Most common indication for fluid therapy is correction of dehydration and resuscitation from shock, hypokalemia, and metabolic acidosis. •     Less common indication for fluid therapy is in cases of acid-base disturbances (metabolic alkalosis or mixed acid-base disturbance), specific correction of other electrolyte disturbances such as sodium, potassium, calcium, magnesium. •     Other indication for fluid therapy is for the treatment of anemia and coagulopathies. Body fluid compartmentalization •     Total body water (TBW) in adults is approximately 60% of body weight. While young animals (neonates 80% and pediatrics 75%) contain more water. Water is located in separate yet

Introduction

Drying is one of the oldest methods of preserving food. Drying and dehydration both can be defined as the process of removing moisture from the foods. It is a simultaneous heat and mass transfer process, wherein heating medium or internal heat generation helps in evaporation of free water molecules from the product. Drying means removal of moisture of food upto a predetermined level where as in dehydration, complete removal of moisture upto bone dry weight of food material. Dehydrated foods have less than 2.5 % moisture content (dry basis) where as dried foods have dry basis moisture content more than 2.5 %. Drying operation consumes energy from 0.38 to 0.63 GJ/ton of food grain. Removal of water from foods using thermal energy thus makes it an energy intensive process. Modes of heat Transfer in various Driers are given in Table 1.Developments in dryer and methods, dryer selection based on form of raw material and typical residence time for various dryer are are given in Table 2,3 and 4, respectively.

Fluorescein diacetate (3’ 6’-diacetyl-fluorescein) is a fluorescein conjugated to two acetate radicals. This colourless compound is hydrolysed by both free (exoenzymes) and membrane bound enzymes, releasing a coloured end product, fluorescein. This end product absorbs strongly in the visible wavelength (490 nm) and can be measured by spectrophotometry. The enzymes responsible for FDA hydrolysis are plentiful in the soil environment. Non-specific esterases, proteases and lipases, have been shown to hydrolyse FDA. The hydrolysis of FDA by soil enzymes can be estimated by methods of Adam and Duncan (2001).

What is FISH ?

Fluorescent in situ hybridization is a technique in which single-stranded nucleic acids (usually DNA, but RNA may also be used) are permitted to interact so that complexes, or hybrids, are formed by molecules with sufficiently similar, complementary sequences. Through nucleic acid hybridization, the degree of sequence identity can be determined, and specific sequences can be detected and located on a given chromosome. Fluorescent in situ hybridization (FISH) is a powerful technique for detecting RNA or DNA sequences in cells, tissues, and tumors. FISH provides a unique link among the studies of cell biology, cytogenetics, and molecular genetics.

Principle of FISH

FISH involves the preparation of short sequences of single-stranded DNA, called probes, which are complementary to the DNA sequences the researchers wish to paint and examine. These probes hybridize, or bind, to the complementary DNA and, because they are labeled with fluorescent tags, allow researchers to see the location of those sequences of DNA. Unlike most other techniques used to study chromosomes, which require that the cells be actively dividing, FISH can also be performed on non dividing cells, making it a highly versatile procedure.

Management of Compound Fracture

An open fracture is an injury that occurs when a broken bone is exposed through the skin. This may mean that the bone is actually sticking out of the skin, or it may mean that the skin and soft-tissue is disrupted and exposes a path to the site of the fracture. Often called a compound fracture, an open fracture necessitates different treatment from the usual closed fracture.

Surgically Cleaning the Bone

Surgically cleaning the bone is one of the first steps for treating an open fracture. Most patients who sustain an open fracture undergo a surgery called “irrigation and debridement.” Irrigation means washing the bone and the site of the injury. Debridement is described in the next step.

Determining the extent of injury can be difficult just by looking at an open fracture. This is especially true in high-energy injuries including automobile collisions and gunshot wounds. With these types of injuries, even small penetrations in the skin can cover very large areas of soft-tissue damage around an open fracture. Therefore, when surgically cleaning the bone, it is important to do this in the operating room (OR) under anesthesia — trying to sufficiently assess and clean the bone in the emergency room, without adequate anesthesia, may be insufficient.

Aim: Regular flushing of compound and fracture using topical antibiotic or antiseptic required to bring the open wound and fracture either to a aseptic stage or to reduce the degree of infection and pus formation.

Procedure

After through cleaning the exposed bone as well as the wound of the compound fracture the wound is placed inside its part.

A thick walled rubber tube / plastic tube threaded with two end of a suture with a straight needle is carried to a higher site from the fracture within the wound.

The suture and needle is brought out, the sutures separated and again threaded and the flushing catheter is fixed with suture. Fig.1.(a) and Fig. 2. (a), (b).

The wound is protected with a thick absorbant sterile cotton padding, keeping the flushing catheter out through a small hole within the bandage. Fig. 1 (b) and Fig.2.(c)

The limb is immobilized as per the recommended procedure depending the level of fracture, outer end of the flushing catheter is kept outside, of the immobilization for carrying out regular flushing of the wound.

Abstract

The anomalies observed in the reverine systems have been demonstrated to be the potential tool in deciphering the tectonically active zones. Such various drainage anomalies viz: radial drainages, anomalous compressed meanders, eyed drainage and the youthful floodplains observed in Annamali – Palani - Varushanad hill ranges of the Western Ghats of Tamil Nadu show that the N-S and NE-SW trending faults are tectonically active in the recent years.
