Realism is a theory that holds that power is the central element of the international system, based on the ability to influence others.

Module Design
What is good vs. bad design?
Good design is characterized by high cohesion and low coupling, meaning each module has a clear, focused responsibility and minimal dependency on other modules. This leads to systems that are easier to understand, test, reuse, and maintain. Good design also emphasizes clarity, simplicity, and well-defined interfaces.
Bad design has low cohesion and high coupling, where modules perform unrelated tasks and depend heavily on each other. This results in systems

Driving Business Growth: Innovation, Sales, and Operations
1. Why Innovation and Sales Go Hand in Hand
Innovation and sales are intrinsically linked: innovation creates new value, while sales deliver that value to customers. A company may develop exceptional products, but without effective sales, those ideas fail to generate revenue. Conversely, sales teams provide critical customer feedback that fuels further innovation. Ultimately, innovation refines the offering, while sales ensure market penetration.

Steps for Recombinant DNA Preparation
1. Isolation of Genetic Material or DNA
Genetic material is present inside the cells. It has to be obtained in pure form without even the attached histones and other proteins. To get the desired DNA, cells are treated with lysozyme (for bacteria), cellulase and pectinase (for plant cells), and chitinase (for fungal cells).
- The treated cells are homogenized and centrifuged to rupture the cells as well as nuclear envelopes.
Understanding Put-Call Parity and Derivatives Markets
Put–Call Parity
This model states that for a given call price, the corresponding put price for the same exercise price and tenure can be determined. This is known as the Put–Call Parity rule.
Consider two portfolios:
- First Portfolio: Stock + Put
- Second Portfolio: Call + Present Value of Strike Price
At expiry, the value of both portfolios will be equal under all conditions.
Analysis at Expiry
Case 1: Stock Price < Exercise Price (e.g., 80 < 100)
- Portfolio A (Stock + Put): Stock price at end +
