IMMUNOBLOTTING
•Viral antigens are detected with a polyclonal or a MAb onto nitrocellulose paper.
▪︎After incubation, the protein bands (immune complexes) are visualized with peroxides-conjugated protein and a color reagent.
• A color develops in the bands where antibody binds to the antigen.•Immunoblotting assay mixture of this two technique.
WESTERN BLOTTING Western blotting is based on the principles of immunochromatography where proteins were separated into poly acryl amide gel according
Biological control represents a sustainable approach to managing pests and diseases by utilizing natural enemies, microbes, and botanical extracts. This strategy is a cornerstone of natural farming, emphasizing ecological balance over chemical intervention.
## 1. History and Concept of Biological Control
Biological control is the intentional use of living organisms—predators, parasites, or pathogens—to suppress pest populations (Gontijo, 2025).
* **Early Records:** The practice dates back to
Natural Farming represents a paradigm shift from chemical-intensive agriculture to a method that works in harmony with nature. It is a holistic approach aimed at restoring soil health, increasing biodiversity, and reducing the cost of cultivation for farmers.
## 1. Introduction to Natural Farming
Natural Farming (often associated with **Masanobu Fukuoka** and, in India, **Subhash Palekar**) is a chemical-free alias of traditional Indian agriculture. It relies on the premise that all the nutrients
Protons — positive charge, found in nucleus
Neutrons — no charge, found in nucleus
Electrons — negative charge, orbit nucleus in energy levels
Atomic Number (Z): number of protons
Mass Number (A): protons + neutrons
Isotopes: atoms of the same element with different numbers of neutrons
Ions: atoms that gain or lose electrons
Gain electrons → negative ion (anion)
Lose electrons → positive ion (cation)
Mass Number:

Six phases/security concerns
Recruitment: The organization checks the applicant’s qualifications, references, and background before hiring. The security concern is reducing insider threats and hiring trustworthy employees.
Onboarding: The employee is officially added to company systems such as payroll and benefits. The security concern is making sure organizational policies and agreements are properly completed.
User provisioning: The employee receives accounts, devices, badges, and system access
A pro forma invoice is a sales document that is issued by the seller, or exporter, before the goods are delivered. It has no fiscal value and the buyer isn't required to pay the amount listed. It is only used as a quotation which the buyer needs for a customs declaration in international shipping or to obtain an import licence - a governmental document that allows the importer to bring the goods into their country. A commercial invoice is a legal document issued by the seller after the goods have
Modern political theory is a systematic study of the state, government, and the fundamental values that govern collective human existence. Unlike classical theory, which was often rooted in idealism and religious morality, modern theory emerged alongside the Enlightenment, prioritizing human reason, secularism, and empirical observation.
To understand its nature for a 15-mark analysis, we can break it down into the following key dimensions:
1. Shift from Idealism to Realism
The nature of modern...
