Thrips : Taeniothrips simplex : Thripidae

Yellow coloured nymphs and black adults damage leaves and spikes by rasping tissues and sucking the sap.  Affected leaves and spikes develop silver streaks, turn brown, get deformed and dry when attack is severe.  Corms in storage are also attacked. Infested corms are sticky, get shriveled and produce weak plants.

Object: To demonstrate that water is lost from a living plant during transpiration. 

Material Required: A potted healthy plant, a bell jar, a rubber sheet or oil cloth, a glass sheet and grease.

Theory: Transpiration: Loss of water in the form of water vapour from the internal tissues of living plants through aerial parts of the plant is known as transpiration.

15.1 Introduction
Milk is a multifaceted physiological fluid that aids infants in their transition to life outside the womb by supporting digestion and development, as well as providing essential nutrients and bioactive components. It promotes the development of beneficial microflora and enhances the growth of lymphoid tissue. Recent research indicates that the quantity and importance of bioactive compounds in milk may be greater than previously believed. Through research, the distribution and presence of essential components in various animal milks have been analyzed. The consumption of dairy products has been linked to health benefits that mitigate the adverse effects of obesity and overweight. These benefits include a decreased likelihood of being underweight, reduced blood pressure, and a reduced risk of stroke, colon cancer, and osteoporosis. Dairy products provide a valuable combination of nutrients, such as proteins, fatty acids, vitamins, and minerals, that are essential for the maintenance of blood health, the support of the nervous and immune systems, the improvement of vision, the support of muscle and nerve function, the maintenance of skin health, the maintenance of energy levels, and the overall growth and repair of the body. Furthermore, dairy products can function as carriers for bioactive compounds and may provide a variety of health benefits, such as improved immune function, reduced risk of cardiovascular disease, reduced bone mass loss, and protection against free radical damage, when consumed in an appropriate quantity. Incorporating fruits and vegetables in a variety of forms—including fresh, desiccated, powdered, juiced, pureed, pulped, or extracted—into dairy products such as yogurt, ice cream, and cheese also presents an opportunity to improve their health benefits.

Family    :    Annonaceae
 
Habit & Distribution 
The plant (Fig. 75 a) is usually planted in gardens, roadside avenues and also cultivated throughout India.

General characters
The plant is a tall evergreen tree having slender and glabrous branches, growing up to a height of 25 feet. The leaves are narrowly lanceolate, glossy green, long with attractive wavy edges. Flowers are yellowish-green, star like structures that give the tree a peculiar hazy appearance. Seeds are smooth and shining. The plant flowers in March-April and bears fruits during July-August.

Bud-worm : Hendecasis duplifascialis : Pyraustidae

This pest is serious on J.sambac. The larvae are dark green with black head which bores into immature buds.  They make a hole on the buds, and feed inside, leaving behind faecal pellets entangled in few silk strands. Webbing is seen in severe infestation and pupation takes place in soil.

Object: To measure rate of transpiration of potted plant by gravimetric (Lysimeter) method. 

Material required: Potted plants, Polythene sheet, Platform and electric balance etc.

Method: Select same size and same type well watered potted intact plants. Seal the pots and the root system with a sheet of polythene so that the water loss to the atmosphere occurs only from the shoot system not from the soil (To check evaporation losses). Immediately record the weight of the potted plant and keep them in different environment such as (1) warm environment (2) cool environment (3) Calm environment.

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.

Jelly:-Jelly is a semi solid product prepared by boiling a solution of pectin containing fruit extract free from pulp after the addition of sugar and acid. A perfect jelly should be transparent, well set, should have original flavour of the fruits, attractive colour and it should be free from dullness. Jelly is mainly prepared by guava, sour apple, wood apple, loquat and papaya. Apricot, pineapple, strawberry etc of low pectin containing fruits can also utilize after addition of pectin powder because these fruits have low pectin contain.

ABSTRACT

The coconut eriophyid mite, Aceria guerreronis Keifer is a serious pest of coconut in Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, Orissa, West Bengal, Maharashtra and Gujarat. The mites reside underneath the perianth of nuts and feed on the soft meristematic tissues of the young nuts. Their feeding damage is evident as scars on the surface of the older nuts. The damage results in reduction in size of nut and increases labour for dehusking the nuts.

Particle density determination is based on the measurements of weight of solids and their volume. The weight of solids is obtained by weighing a sample of oven dried soil. The volume of solids is determined is determined by immersion. The method outlined here is “Pycnometer method”.

Principle

A given amount of dry soil when immerses in a definitive volume of water, expels air and results in the displacement of equal volume of water. The volume of soil particles is determined by measuring the volume of water displaced in the pycnometer bottle.

Soil bulk density (BD) or apparent density is determined in -situ by core method. Stainless steel or metallic cores of cylindrical shape with known height and diameter are inserted into the soil till the rim of the core. The soil core is then excavated and the soil sample is oven dried to get the dry weight. The ratio of the oven dry weight to the total volume of the core gives the bulk density of the soil.

Etiology

It is a relatively rare skin disease or dermatologic condition. Hypersensitivity reaction is one of the suggestive cause for this condition characterized by nodules or plaques which are seen in the skin, oral mucosa and external ear canal.

The Dumas combustion method, named after the renowned French chemist Jean-Baptiste Dumas, is a widely recognized analytical technique employed in the determination of the elemental composition of organic compounds. This method involves the complete combustion of a sample in an oxygen rich environment, followed by the separation and subsequent analysis of the resulting combustion products.

Principle

The Dumas combustion method involves the complete combustion of a sample in the presence of excess oxygen. The nitrogen present in the organic compound is converted into nitrogen gas (N2 ), which is then measured quantitatively. The process can be summarized as follows:

i. Combustion: The sample is combusted at high temperatures (typically around 900-1000°C) in the presence of oxygen. This results in the conversion of all organic material into carbon dioxide (CO2 ), water (H2 O), and nitrogen gas (N2 ).

ii. Removal of Interfering Gases: The combustion products are passed through various reagents to remove interfering gases such as CO2 and H2 O.

iii. Detection of Nitrogen: The nitrogen gas is then measured, often using a thermal conductivity detector (TCD) or another suitable detection method.
