Chromosome No. : 2n = unknown

Origin
Feijoa is native of subtropical South America, widely distributed in western Paraguay, parts of Argentina southern Brazil and Uruguay.

Uses
All parts of the plants are edible, the fruit has great resemblance to guava in respect of its appearance and size and other important pomological traits. Usually consumed as dessert or cooked, petals being thick are used in salad, on accounts of its high fruit flavour is also made into jams, jellies etc., besides these fruit juice is used to add aroma to non-alcoholic beverages.

Introduction

Casein has been widely used as a substrate for measuring the trypsin inhibitor activity of natural trypsin inhibitors such as those which occur in Soybeans and other legume. The most common method employing casein is the one originally described by Kunitz (1947) which involves the spectrophotometric determination of the breakdown products produced by a given concentration of trypsin in the presence and absence of the inhibitor. On the other hand, the tryptic hydrolysis of a synthetic substrate such as benzoyl-DL-arginine-p-nitroanilide (BAPA), first introduced by Erlanger et al. (1961), does follow a zero order reaction, and one obtains, within broad limits, a linear relationship between the quantity of p-nitroaniline released and the concentration of the active enzyme. Although BAPA has been used for assaying the antitryptic activity of soybean fractions (Sambeth et al., 1967).

ORIGIN OF INSECT

Entomology is a branch of zoology which deals with insects. In this branch we study the insect origin and evolution of insect and their diversity and classification and other parts of insect body. Insects belong to the class insecta in the phylum arthropoda, the largest group in the animal kingdom. All arthropods are characterised by having segmented body, claws, chitinous exoskeleton, ventral nervous system and dorsal heart. The class insecta is generally considered to have evolved from myriapod of some sort during the Devonian period. Based on different mandibles and mandibular movement concluded that insects are not direct insect group myriapods the mouth is located between the prostomium and the first body segment and the anus open in the periproct.
The first great step was the development of a pair of ventral appendage. Insect legs on each body segments and locomotion, parallel to this an improvement in the sense organs of the head occured eyes and Antenna were the ultimate result this level of organisation is met in onychophora. A series of diagramms is helpful in a very simplified way in visualising the hypothtical origin of insects.

ABSTRACT

Medicinal plants are the most important source of life saving drugs for the majority of the world’s population. Therefore the biotechnological tools are important to select, multiply and conserve the critical genotypes of medicinal plants. With the increase in the demand for the crude drugs, the plants are being overexploited, threatening the survival of many rare species. Also, many medicinal plant species are disappearing at an alarming rate due to rapid agricultural and urban development, uncontrolled deforestation, and indiscriminate collection. Advanced biotechnological methods of culturing plant cells and tissues should provide new means for conserving and rapidly propagating valuable, rare, and endangered medicinal plants. Maintenance of germplasm in the green house or in the field has many difficulties and so there is a need for the in vitro conservation of these plant germplasm. In the present paper we report the in vitro conservation of two medicinal plants and each of it has its own medicinal value. The tuberous roots of Holostemma are medicinally important and are utilized as a major ingredient of the drug ‘jivanthi’. Tylophora is used as a herbal medicine and the plant has been traditionally used as a folk remedy for the treatment of bronchial asthma, bronchitis and dermatitis. Shoot buds of these plants were cultured in Murashige and Skoog’s (1962) medium with different strengths and with different concentrations of sucrose and mannitol. The different treatments induced varied response with respect to the slowing of growth of cultures. Sucrose was found essential in combination with mannitol to induce maximum reduction in the growth of the plant tissues. The cultures could be maintained without sub culturing for over one year and resumed normal growth on transfer to mannitol free medium. This method of conservation has many advantages.

Amaranthus is one of the main genera of large and taxonomically diverse group of leafy vegetables. Amaranthus is the cheapest dark green leafy vegetable because of low production costs and high yield. It is often described as poor man’s vegetable.

Origin and Distribution: The main vegetable type Amaranthus tricolor L. originated in South or South East Asia, particularly in India. Budhist monks and Muslim invaders took the crop to neighboring countries. Another vegetable type A. dubius shows diversity in Central America, Indonesia, India and in Africa. A lividus is a popular leafy vegetable in Southern and Central Europe. Amaranthus included 50 to 60 species.

Genetic purity (trueness to type) of a variety can deteriorate due to several factors during production cycles. The best means to insure genetic purity therefore, would be to overcome to the greatest possible extent the various factors responsible for genetic deterioration. The important factors of apparent and real deterioration of varieties as listed by Kadam (1942) are as follows:

Developmental variations

Mechanical mixtures

Mutations

Natural crossing

Minor genetic variations

Selective influence of diseases

The technique of the plant breeder

Ergonomics, also known as human factors engineering, is a multidisciplinary f ield that focuses on designing and arranging environments, products, and systems to fit the people who use them. The primary goal of ergonomics is to enhance efficiency, safety, and well-being by optimizing the interaction between humans and their work environment.

Key Aspects of Ergonomics

Physical Ergonomics

Posture : Examining how people sit, stand, and move to prevent musculoskeletal disorders and discomfort.

Repetitive Motion: Addressing issues related to tasks that involve repetitive movements, which can lead to strain injuries.

Pets provide companionship, emotional support, and numerous health benefits to their owners. However, they can also be carriers of zoonotic diseases— diseases that can be transmitted from animals to humans. Understanding these risks and implementing measures to reduce them is crucial for maintaining the health and safety of both pets and humans. This article explores common pet-associated zoonotic infections and offers strategies to minimize the risk of transmission.

Common Pet-Associated Zoonotic Infections

1. Rabies

• Cause: Rabies is caused by the rabies virus and is transmitted through the bite of an infected animal.

• Symptoms in Humans: Initial symptoms include fever and headache, progressing to neurological symptoms such as confusion, hallucinations, and paralysis. Rabies is almost always fatal once symptoms appear.

• Prevention: Vaccination of pets, avoiding contact with wild animals, and immediate medical attention after potential exposure.

The English term pecan comes from the Algonquian Indian word paccan or pakan, meaning a nut so hard that it had to be cracked with a stone or a nut requiring a stone to crack. Pecan nut is native to North America and United States produces about eighty per cent of the world’s pecans. The Spaniards called it a “type of walnut”. Subsequently, the French turned it into “La Pacaniere”. Eventually, the name pecan nut was created. The nuts of the pecan are edible, with a rich buttery flavour. They can be eaten fresh or used in cooking, particularly in sweet desserts.

Fumigation is a method of pest control that completely fills an area with gaseous pesticides to suffocate or poison the pests within. It is utilized for control of pests in buildings, soil, seed, and grain produce. It is also used during processing of goods to be imported or exported in order to prevent transfer of exotic organisms. Fumigants are chemical compounds in gaseous form that enter the body of insect through the spiracles spread all over via trachea and tracheoles. The important fumigants are Methyl bromide, Ethylene dibromide, Aluminium phosphide, Ethyl formate, Hydrogen cyanide, Chloropicrin etc.

Genus : Syzygium 
Species : aromaticum
Family : Myrtaceae
Chromosome No. : 2n = unknown

Origin and Distribution

The wild species are found growing wild in New Guinea and its cultivation was found on some islands of Moluccas. By the 17th century its cultivation has spread to number of other islands and from Moluccas crop reached Asia. The Britishers further introduced it to in India, Sumatra, Sri Lanka and other countries of south east Asia. Through French, the crop reached Mauritius which further spread to Madagascar, Zanzibar (Africa) and finally reached tropical America (Brazil).

Uses
Chinese valued clove as a spice. In India, regarded as an important spice, dried clove buds or after grinding are used to flavour food, valued for medical purposes (flower and fruit) in south east Asia.

ABSTRACT

Cashew (Anacardium occidentale L.) is a woody perennial tree of tropical origin, belonging to the family Anacardiaceae. Cashew is being cultivated in India, Brazil and Africa countries. It is well known for its food, noon food and medicinal uses. In vitro clonal propagation of cashew, which is an effective method for large-scale multiplication of trees was tried. Cashew plantlets were regenerated from shoot explants of 2 - 3 year old grafted plants, which were regularly sprayed with Bavistin 0.1 per cent at weekly intervals. Among the different surface sterilization treatments used, a combination of antioxidants, antibiotics and fungicides was found to be better with around 40 per cent contamination free cultures being obtained. MS medium containing full strength macro elements supplemented with Kinetin (5 mg l ^-1), NAA (1mg l ^-1) and Brassinolide (0.1 mg l ^-1) was found to be best for shoot proliferation and shoot elongation. Micro shoots were rooted in vitro at a frequency of 70-80 per cent, when cultured for 4-8 days in quarter MS liquid medium supplemented with IBA (1mg l ^-1) after the pulse treatment with IBA (100 mg l ^-1) for two minutes. The average number of roots ranged from 3 - 5 with an average length of 1.63 cm. About 50 - 60 per cent of the rooted microshoots survived wearing and produced healthy and vigorously growing plants, which were transferred successfully to the field.

The demographic transition theory is one of the most important population theories which is the best documented by the data and statistics of recent demographic history. In its original form, the demographic transition theory was put forward by W. S. Thompson (1929) and Frank W. Notestein (1945). These scholars based their statements and arguments on the trends in fertility and mortality, being experienced in Europe, North America and Australia.

The theory postulates a particular pattern of demographic change from a high fertility and high mortality to a low fertility and low mortality when a society progresses from a largely rural agrarian and illiterate society to a dominantly urban, industrial, literate and modern society. The three very clearly stated hypotheses involved in the process are:

1. The decline in mortality comes before the decline in fertility.
2. The fertility eventually declines to match mortality and
3. Socio - economic transformation of society takes place simultaneously with its demographic transformation.

In the present – day world, as would true of any point in time, different countries of the world are at different stages of the demographic transition. In the opinion of Trewartha, this is largely due to the dual nature of man. According to him, biologically, man is same everywhere and is engaged in the process of reproduction but culturally man differs from one part of the world to another. It is the cultural diversity of man that gives rise to varying fertility patterns in different areas resulting in different stages of demographic transition.

The demographic transition theory is characterized by conspicuous transition stages. The transition from high birth and death rates to low rates can be divided into stages. In the words of E.G. Dolan, “Demographic transition refers to a population cycle that begins with a fall in the death rate continues with a phase of rapid population growth and concludes with a decline in birth rate”.

The selection of individual animals from a group is very important in a livestock farming business. While creating a herd, every farmer should buy animals from a trustworthy disease-free herd and learn as much as they can about the animals. Once the herd is established, the selection of gilts and boars for replacement in the breeding herd should be based on type and performance. The following are important criteria to consider while creating a healthy sow herd:

• Size of litters
• Strength and vigour of litters
• Milking ability
• Temperament

Farm electricity refers to the electrical systems and infrastructure used in agricultural operations to power various equipment, machinery, and facilities. The electrification of farms has become essential for modern agriculture, enhancing efficiency, productivity, and the overall management of farming operations. Description about the farm electricity:

Components of Farm Electricity

Power Supply: Farms are typically connected to the electrical grid, providing a reliable power supply. In some remote areas, farms may rely on off-grid solutions, such as diesel generators, solar panels, or wind turbines.

Power Distribution: Electricity is distributed across the farm through a network of power lines, transformers, and distribution panels. The distribution system ensures that power is delivered to various farm structures and equipment.

Natural disasters like cyclone, earthquakes, flood etc. can happen suddenly and put everyone, including our pets, in danger. Taking care of your dog during such situation means being prepared, staying calm and knowing what to do. This article provides simple steps to help you care for your dog during a disaster.

Before a Disaster make an emergency plan

i. Find Safe Spots: Identify safe places in your home and community where you can go with your dog.

ii. Know evacuation routes: Plan different ways to leave your home in case one way is blocked and find pet-friendly shelters in your area.

iii. Emergency Contacts: Keep a list of important contacts, such as your vet, local animal control, and pet-friendly hotels.

Introduction
Public speaking is both an art and a science. It’s about effectively delivering a message to an audience in a way that is clear, engaging, and impactful. Successful public speaking requires not only a well-structured message but also a mastery of delivery methods. How a speaker delivers their message can significantly influence how it is received, understood, and remembered by the audience. This chapter will explore the various modes of delivery in public speaking and provide a checklist to guide speakers in enhancing their effectiveness.
Modes of Delivery in Public Speaking
Public speaking is commonly categorized into four primary modes of delivery, each suited to different contexts, audiences, and types of messages. Choosing the right mode is essential for maximizing engagement and ensuring clarity.
Manuscript Speaking
Manuscript speaking involves reading a written script word-for-word. This mode is typically used in formal situations where precision is critical, such as legal proceedings, political addresses, or scientific presentations.
Advantages
• Ensures accuracy and consistency in wording.
• Reduces the likelihood of errors in complex or sensitive topics.
Disadvantages
• Can lead to a lack of engagement if the speaker reads in a monotonous tone.
• Limits eye contact and interaction with the audience.
Best Used For
• Formal events where exact wording is essential (e.g., policy announcements).
• Speeches on technical or sensitive topics requiring precision.

Japanese persimmons were introduced into the United States from Japan by Admiral Perry who discovered the fruit growing on the coast of Southern Japan in 1851. It is regarded as the national fruit of Japan and several improved cultivars have been developed there. It is the one of the easiest tree fruits to grow in the home landscape and also the most beautiful especially in fall when the foliage turns to brilliant colours and huge orange fruits hang from the tree like ornaments.

Abstract

On the basis of symptoms, samples from seven localities within Solan district (H.P.) at varying altitudes ranging from 600-1650mts comprising Nalagarh (600-750m), Badghal (850m), Dilchab (950-1000m), Shaya (1200m), Solan (1300-1450m), Bajhyana (1520m) and Tikari Pajahali (1650m), were collected and used for serological detection by DAS ELISA. It was found that all the isolates except Nalagarh, reacted positively with the antisera to ToLCV, thus substantiating the results on the identity of the present isolates. Out of the seven isolates under study, Dilchab and Shaya isolates did not show any PCR amplification for Rep gene indicating the variability in the regions flanking the Rep gene. Likewise, no amplification result in case of Nalagarh sample proposes the attack of some other pathogen producing similar symptoms.
