Diamagnetism is a form of magnetism that occurs in materials that are not attracted to magnetic fields. It is characterized by the phenomenon where certain materials weakly repel magnetic fields. This property arises due to the motion of electrons within atoms. When an external magnetic field is applied to a diamagnetic material, the magnetic field induces a temporary change in the orbital motion of the electrons, leading to the generation of a weak magnetic field in the opposite direction.

The Zener effect is a phenomenon observed in certain types of diodes, specifically Zener diodes, which are designed to allow current to flow in the reverse direction when a specific, predetermined voltage (the Zener voltage) is reached. When the reverse voltage applied across the Zener diode exceeds this Zener voltage, a mechanism known as the Zener breakdown occurs, which allows current to flow in the reverse direction without damaging the diode.

Contact resistance refers to the resistance to current flow that occurs at the interface between two conductive materials, such as metal contacts or between a conductor and a semiconductor. This resistance is typically very small compared to the bulk resistance of the materials involved, but it can significantly affect the overall performance of electronic devices, electrical connections, and circuits.

CppUnit is a C++ unit testing framework, inspired by the JUnit framework for Java. It is designed to facilitate unit testing in C++ applications by providing a set of classes and macros to create and manage test cases, test suites, and assertions. Key features of CppUnit include: 1. **Test Case Organization**: CppUnit allows you to define test cases as classes that inherit from `CppUnit::TestFixture`. This makes it easy to organize and manage tests.

Gustav Jacob Born, often referred to as G.J. Born, is a notable figure in the field of biomedical sciences, particularly known for his contributions to pharmacology and the study of blood cells. He is recognized for his research on the mechanisms of action of various drugs and the physiological processes related to blood and immune responses.

The Stargate is a fictional device featured in the "Stargate" franchise, which includes movies and television series. In the storyline, the Stargate is a large, ring-shaped portal that allows for instant travel between distant planets. It achieves this by creating a stable wormhole when it is activated with a specific sequence of symbols (known as the "Dial Home Device," or DHD).

Akkihebbal Ravishankara is a notable Indian scholar, educator, and social activist primarily associated with the field of Kannada literature and culture.
