        Odia- Arakha

Family    :    Asclepiadaceae
 
Habit & Distribution
It is a shrub (Fig. 27 a), common weed, mostly found in disturbed sites, roadsides, and wastelands and roadsides. It is widely distributed in hot and dry areas of India.

General Characters
The plant is a shrub that grows up to 4 m in height. Leaves of the plant are opposite, gray green, broadky elliptic, large upto 15 cm long and 10 cm broad with a pointed tip. Flowers are waxy white, 5 petals, purple tipped inside and with a central purplish crown. Fruits are gray-green, inflated 8-12 cm long and contain numerous seeds. Flowering and fruiting occur during December and July. 

India has a total geographical area of about 329 million hectares which represents about 2.4% of the world’s total landmass but it harbours a total of 47,513 plant species. Out of about 0.4 million species known in the world, it represent as much as 11.4% of world flora. About 28% of plants that occur in India are endemic to the country. The ecological or ecosystem diversity of the country is enormous, ranging from sea level to the highest mountainous ranges in the world, hot and arid conditions in the northwest to cold arid conditions in the trans-Himalayan region, tropical wet evergreen forests in Northeast India and the Western Ghats and mangroves of Sundarbans.

The disease appears as tumour like swelling or galls on leaf veins, leaf stalks, peduncles, stems and on fruits. The galls on the vein give a swollen and hanging appearance to the leaves. These are elongated, looks glossy in beginning but later rupture to become rough and corky. When stems remain succulent, numerous tumours may form on them. In severe case, the plant may kill prematurely.

Future scope of the Research

The present study has been conducted by driving the insights deeper into the nature, intensity and character of the problems creating barrier against the farmers happiness and there mental health. The present study thus leaves behind the following domains to be researched out in future:

The study can be extrapolated to other domains of mental health and happiness:

Artificial insemination (AI) is a technique in which sperm cells loaded in straws and stored in liquid nitrogen are thawed and manually deposited into the reproductive tract of a female animal at estrus. The recto-vaginal technique is the most commonly used method for artificial insemination in cattle. In order to increase the probability of pregnancy, the animal in estrus should be inseminated at proper time not too early or late.

Determination of porosity of tin plate.

Introduction

Porosity in tinplate refers to the presence of tiny holes or pores in the tin coating on steel sheets used for making tin cans. These pores can expose the underlying steel to the contents of the can, potentially leading to corrosion and contamination of the food product. Ensuring minimal porosity is crucial for maintaining the integrity and safety of food packaging. Tinplate is produced by coating a thin layer of tin onto a steel sheet. This can be done through hot dipping or electroplating. The goal is to create a uniform and continuous tin layer that acts as a protective barrier against corrosion. During the coating process, imperfections such as pores or pinholes can form in the tin layer. These imperfections can occur due to variations in the coating thickness, impurities in the tin, or mechanical damage during handling and processing.When a tinplate can with porosity is filled with food, the contents can come into direct contact with the exposed steel through the pores.The acidic or basic nature of certain food products can accelerate the corrosion of the exposed steel, leading to the formation of rust.This corrosion can compromise the structural integrity of the can and potentially contaminate the food with rust particles or harmful by-products of the corrosion process. The primary function of the tin coating is to act as a physical barrier that prevents the food from contacting the steel. A continuous and defect-free tin layer ensures effective protection.Tin also provides cathodic protection to the steel. In the presence of an electrolyte (e.g., acidic food), tin acts as the sacrificial anode, corroding preferentially to the steel. However, this mechanism is only effective if the tin layer is relatively thick and the porosity is minimal.

Particle density of soil is the ratio of mass and volume of soil solids. Particle density of soil is an important physical characteristic because the interrelationships of porosity, bulk density and air space, and rates of sedimentation of particles in fluids depend on particle density.

Principle

The determination of particle density (ρ_p) requires the measurement of mass of the solid and its volume. The mass is obtained by weighing the oven- dry soil sample and volume by calculating from the mass and density of water displaced by the sample in a pycnometer. The pycnometer is a glass flask with a ground glass stopper having a capillary opening. The particle density can be calculated using the following equation:

Audio-visual aids serve to complement extension and development workers rather than replace them. Not all aids are suitable for every occasion, but there are specific aids that should be carefully chosen and utilized for each particular situation. There is no universal rule for selecting and employing audio-visual aids to ensure effectiveness in all circumstances. To achieve the most effective outcomes, extension workers should:

• Choose the appropriate aids,

• Employ a suitable combination of selected aids,

• Utilize them in the correct sequence.

Audio-visual aids are employed individually or in combination, taking into account the following factors:

1. Size of Audience: Video presentations or whiteboards may not be effective when the audience exceeds 30 participants. Leaflets, bulletins, or handouts are suitable for one reader at a time, while public address systems or internet messages are suitable for large audiences.

2. Nature of Audience: Printed media are suitable for literate individuals, while exhibits, pictures, and symbols are more appropriate for those with lower literacy levels.

3. Teaching Objective / Expected Nature of Change: Audio-visual aids should be selected based on the objective of extension teaching, whether it aims to change:

• Thinking or knowledge,

• Attitude or feeling,

• Actions or skills.

How to do edible packaging of food sample.

Introduction

Edible Packaging – An edible film or coating is simply defined as a thin continuous layer of edible material formed on, placed on, or between the foods or food components. The package is an integral part of the food, which can be eaten as a part of the whole food product.

Edible packaging can be done in two types:

Edible coating: Edible coating are applied and formed directly on food (e.g. by spraying, immersion, and fluidization) via a coating solution. This will be a part of the food and must not provoke unwanted change (organoleptic, physical, and chemical).

Abstract

Nutrition is basic to sustainable development being concerned with ensuring food at all times in terms of quality and quantity. As a bridge between food and health it interlinks several variables such as environment and protection from illness and disease, which helps to lead to an optimal quality life. Despite the substantial progress made in India’s food production, serious nutritional challenges continue to threaten her development in human resource development more so rural women are particularly vulnerable to malnutrition. Poor nutritional status of women during adolescence and their resultant vulnerability to anaemia during pregnancy contributes to a higher level of low birth weight children and if it happens to be girl child then the vicious cycle continues. Although food is available through markets at the district and village level, food security at the house hold level becomes a challenge because of lack of purchasing power. Women contribute significantly to agriculture production; on an average their contribution will be around 55-65 per cent. Hence, conscious effort is needed to develop an intervention strategy. One such strategy would be empowerment of women through transfer of technology, which will help in income generation especially during lean agriculture seasons. Priority areas in the field of nutrition for technology transfer would be processing, preservation and value addition of agro based crops. However, training is required for skill upgrading and capacity building of women.
