Family    :    Euphorbiaceae

Habit & Distribution
The plant is a shrub, usually planted in gardens.

General Characters
It is a small erect and branched shrub (Fig. 57 a). The leaves are entire, elliptic-oval, may be fiddle shaped with 7 inches long. The flowers are red and pink and about 2.5 cm across and borne in many flowered clusters at branch end. Fruit is rounded-trigonous. The plant bears flowers and fruits in most parts of the year.

Etiology

Superficial pyoderma usually occurs in the epidermis and upper infundibulum of the hair follicle. It usually heals without scar formation and commonly caused by Gram positive cocci Staphylococcus spp., particularly exfoliative toxin of this species.

This order includes cockroaches and grasshoppers. They bear the following characters:

1. The body is oval and flattened in cockroach and elongated in grasshopper.

2. Two pairs of wings are present. Mesothoracic pair of wings is thickened (Tegmina) and act as cover for membranous metathoracic pair of wings.

3. Antennae are long and multi-jointed.

4. The legs are modified for fast running (cockroach) or jumping (grasshopper).

5. Metamorphosis is incomplete.

Common name    :    Odia- Laoo
        English-Calbash     
        Hindi- Lauki

Family    :    Cucurbitaceae

Habit & Distribution
The plant is a climber (Fig. 58 a), commonly cultivated and distributed throughout India.

General Characters
It is an annual vigorous herb, running or climbing vine with large leaves and with lush appearance. Leaves are simple, 17-20 cm diameter, short and softly hairy with kidney or heart shaped outlines. Flowers are white, up to 4 inches in diameter with spreading petals. Fruits are of various shapes, in different varieties, like bottole or dumbbell shaped, rounded or elongated. The plant flowers during July-January and bears fruits during cold season.

Lace wing bug: Monantha globulifera : Tingidae

Eggs are inserted slantingly into leaves and other tender foliage.  Black spiny nymphs and lace winged adults suck the sap from leaves. Attacked leaves develop yellow patches become brown, shrivel and dry up in severe cases.

Leaf feeder : Helicoverpa armigera : Noctuidae

The female moth lays eggs on tender foliage. Young larva feeds on tender foliage and starts infesting the older ones in later instars. A single caterpillar can destroy many leaves

Poor quality roughages includes the wheat straw, commonly fed to ruminants but unable to provide any DCP. Urea ammoniation method, not only improves the nutritive value of straw in terms of DCP and TDN, but it also improves the dry matter intake of animal by improving its palatability. In this method of urea ammoniation, one quintal of wheat straw is treated with 4 kg fertilizer grade urea (4%) by dissolving in 40 litre of water (moisture 40%). The dissolved urea is sprayed over several layers of wheat straw and mixed properly and then kept under airtight condition by covering it with polythene sheet for a period of 4 weeks. With the presence of enzyme urease the urea get broken down in to ammonia and carbon di oxide. This ammonia on one hand improves the nitrogen content of the straw and on another hand alkalinity (by ammonia and by ammonium hydroxide) reacts on the lingo-cellulosic bonds to loosen their strength. So by increasing the nitrogen content of the straw it increase the nutritive value of the straw in terms of increasing the DCP value of the straw and on another hand by reducing the bonds of lingo-cellulose it increase the digestibility of crude fiber and hence it also increase the energy (TDN) content of the straw.

Etiology

It is caused by Staphylococci spp- characterized by superficial pyoderma in dogs. It is mainly due to exfoliative toxins of S? aureus.

Gross pathology

The lesion reveals cutaneous exfoliation, vesicles, pustules (Figure 6) and crust.

Pesticide poisoning occurs when a pesticide penetrates the body and disrupts its essential systems. Symptoms can appear anywhere from a half hour to 24 hours following exposure. The common symptoms and indicators of pesticide poisoning are:

Initial symptoms may include

First Aid

First aid is the preliminary care of a person who has been exposed to pesticides before getting proper medical attention. The initial step is to remove the person from the source of the exposure by removing pesticide from their skin, removing contaminated clothing, or transporting them to fresh air. Be careful not to contaminate oneself throughout this process.

Pesticide on the Skin

• Remove any contaminated clothes.

 • Drench clothing and skin with plenty of water.

• Clean hair and skin with soap and water.

• Dry the victim and wrap them in clean clothes.

• Prevent the victim from being chilly or overheated.

According to Thornthwaite’s method of climatic classification, six major types of climates exist in India (Fig. 14.1) as stated below:

14.1 Perhumid Regions of India (A)

These regions receive rainfall of more than 2500 mm and consist of Konkan region along Western Ghats, Kerala and most parts of northeast India covering Assam, Meghalaya, Arunachal Pradesh and Tripura etc.

14.2 Humid Regions of India (B)

These regions receive annual rainfall ranging from 2000-2500 mm and are found in areas adjoining perhumid climate.

Common name    :    English- Wild sage 
        Hindi- Raimuniya 
        Odia- Naguari

Family    :    Verbenaceae
 
Habit & Distribution 
It is a shrub (Fig. 59 a), commonly found in roadsides, wasteland, damp site etc. It is distributed throughout India.

General Characters
The plant is an evergreen shrub grows up to 6 ft height and may spread 8 ft in width. The leaves are ovate-oblong, about 2-5 inches long with rounded tooth edges and a textured surface. Stem and leaves surfaces are covered with rough hairs and emit an unpleasant aroma when crushed. Flowers usually white-pink or orange-yellow in colour and are held in clusters that are typically 1-2 inches across. Fruits are small, globose, fleshy, purplish black berries after ripe. The plant bears flowers and fruits in all round the year.

Ultra freezing: Cryopreservation of seeds immersed in liquid nitrogen (LN₂) at a very low temperature, -196^ºC, can be used for many seeds provided the moisture content is relatively low, about 8 to 15 percent and the seeds are in sealed containers.

Unclassed forest: Forest land owned by Government but not constituted in to a reserved, village or protected forest.
 
Under bark: Measurement of the diameter or circumference of a trunk or branch made with the bark removed. See also Over bark.

Semilooper: Thysanoplusia(Plusia) orichalcea : Noctuidae

Bluish green or grey coloured eggs are laid singly on lower surface of leaves.The larvae are semi loopers and feed voraciously on leaves and cause defoliation of the plants.

Aim: To know the method of securing thomas splint, in the forelimb.

Description

After immobilising the fracture site covering the distal as well as proximal end properly the thomas splint is fitted over the forelimb.

The foot is immobilised to the distal end of Thomas splint.

The immobilised forelimb kept closed and straight with the posterior extension of bamboo of the thomas splint. The limb is fixed with posterior bamboo splint with bandage roll at several place to avoid anterior, posterior movement of the limb.

At the time of fixing the limb with posterior extension bamboo of the Thomas splint, bandage are rapped along with the netting of thomas splint, to avoid medullary lateral movement of the immobilised limb.

Finally the immobilised forelimb is rapped along with the bandage roll including both the anterior and posterior extension of bamboo splint.

To avoid outside movement of the immobilised limb, the method of immobilisation of fracture of forelimb has been shown in fig-1.

ABSTRACT

Bats: A colony of 500 insectivorous bats of Hipposideros speoris inhabited a natural cave in Madurai (9^O58’ N. lat; 78^O10’ E long). At a depth of 40 m, the cave experiences a constant temperature of 27 + 0.1^OC, 95 % relative humidity and absolute and perpetual darkness. Therefore there were no day/night cues. Yet all the members of the bat colony flew out 10 to 15 min. after sunset as though they knew the time of sunset. Recorded flight and rest experiments in flight activity cages and a hand-wound Thermohygrograph drum 40 m from the cave mouth over periods of 50 days revealed that the free-flying conspecific bats were socially synchronizing the activity patterns of the three captive bats. Bats were telling other bats time.

Mice : In the field mouse, Mus booduga the mother conveys information of day and night to her pups by means of her presence and absence (PA) cycles. Her presence meant day and absence denoted night. We named this phenomenon maternal entrainment. Such entrainment of the time sense of the pups was possible if in every cycle the mother was presented for a minimum of 8 hr but not exceeding 16 hr. Therefore 8 hr and 16 hr describe the limits of maternal entrainment.

Common name    :    English- Angled luffa
        Hindi- Karvitori
        Odia- Pita taradi

Family    :    Cucurbitaceae

Habit & Distribution 
The plant is a climber (Fig. 60 a), widely cultivated and also found in wild. It is cultivated throughout India.

General Characters
It is an annual climber with smooth and angled stem. The leaves are 5-7 lobed or angled, 7.5-15 cm across and covered with short hairs. Flowers are yellow in colour with male and female in the same axil. The fruits are ribbed and cylindricaly shaped and 1-2 feet in length. The plant bears flowers and fruits during August-November.

Thrips : Thrips flavus : Thripidae

Infestation of thrips is generally during hot months with high night humidity.  The attack by thrips leads to discolouration, bronzing and drying of affected leaves.

Semilooper : Thysanoplusia orichalcea  : Noctuidae

Bluish green or grey coloured eggs are laid singly on lower surface of leaves.  Larvae feed voraciously on leaves and defoliate plants.

LAB constitutes a group of gram positive bacteria. They are nonsporulating, nonrespiring but aerotolerant cocci or rods, which produce lactic acid as one of the main fermentation products of carbohydrates, they do not have cytochromes. They belong to the phylum Firmicuttes, class Bacilli and order Lactobacillaceae. The group includes several genera such as Lactobacillus, Lactococcus, Bifidobacterium, Pediococcus, Enterobacter, Corynebacterium, Streptococcus, Leuconostoc etc.

Abstract

Self Help Group (SHG) has emerged as a new paradigm for combating poverty and self help promotion has become one of the major developmental strategy in the country today. The self help groups are motivated to take up suitable micro entrepreneurship for income generation either individually or in groups, which is dependent on the resource availability and their skills. The empowered SHG women have started different small enterprises such as papad making, malt preparation, different value added products, and other agro based industries which has increased their income. In recent years agro processing and value addition to the farm produce have attained great socio economic significance. A massive thrust to food processing and other agro based industries will add value to the product there by increasing the income of farmers, create employment opportunities, diversify rural economy and foster rural industrialization.
