Shiva Uranium Limited is a company that was involved in the uranium mining and exploration sector. It primarily focused on uranium projects in countries with existing mining infrastructure, often exploring for new deposits and potentially developing uranium mining operations. The company was listed on stock exchanges and aimed to contribute to the energy sector, particularly in relation to nuclear energy, which utilizes uranium as fuel. However, it is important to note that companies' statuses, projects, and market relevance can change over time.

A neutron reflector is a material used in nuclear reactors and certain experimental setups to reflect neutrons back into a nuclear reaction zone, thereby increasing the effective neutron economy of the system. By reflecting neutrons that would otherwise escape or be absorbed by surrounding materials, neutron reflectors can enhance the efficiency of nuclear fission processes or contribute to sustaining a chain reaction.

Phytosanitary irradiation is a pest control method that involves exposing agricultural products, particularly fruits and vegetables, to ionizing radiation to eliminate pests and pathogens. This technique is used primarily for the purpose of ensuring the safety and quality of food items during international trade, helping to prevent the spread of invasive species and plant diseases between regions.

A plasma lamp is a type of gas discharge lamp that produces light and visual effects by creating an electric arc through a low-pressure gas, typically noble gases such as neon or argon, inside a glass or clear plastic globe. The most well-known design is the plasma globe, which features a central electrode surrounded by a glass sphere filled with gas, and produces colorful, tendril-like patterns of light when a high-frequency voltage is applied.

Reversed Field Pinch (RFP) is a type of magnetic confinement system used in plasma physics and fusion research to confine hot plasma in a toroidal (doughnut-shaped) configuration. It is a variant of the pinch concept, which relies on the principles of magnetic fields and currents to confine and stabilize plasmas.

Kapitza instability refers to a phenomenon in physics observed in certain systems, particularly in the context of fluid dynamics and systems exhibiting oscillatory behavior, where a stable state can become unstable due to rapid changes in conditions or external forces. The term is named after the Russian physicist Pyotr Kapitza, who studied this kind of instability in the mid-20th century.

A bandwidth-limited pulse is a signal or waveform that has been restricted in its frequency content or bandwidth. In the context of signal processing and telecommunications, a pulse is typically a transient signal that varies with time and can be characterized by its shape, duration, and the frequency components it contains. The key characteristics of bandwidth-limited pulses include: 1. **Frequency Limitation**: The pulse is designed such that its frequency spectrum does not exceed a certain maximum frequency.

A beam expander is an optical device that increases the diameter of a beam of light, typically a laser beam. It is used to improve the characteristics of the beam, such as its divergence, intensity distribution, and focusability. Beam expanders are commonly employed in various applications, including telecommunications, material processing, optical imaging, and laser manufacturing.

Gain-switching is a technique commonly used in laser technology to generate short and intense pulses of light. It is primarily employed in solid-state lasers and semiconductor lasers. The process involves rapidly varying the gain of the laser medium, which in turn affects the output intensity and timing of the emitted light.

Photoionization mode refers to a process where an atom or molecule is ionized through the absorption of photons, typically in the ultraviolet (UV) or X-ray range. In this process, the energy of the incoming photons is sufficient to remove one or more electrons from the atom or molecule, resulting in the formation of positive ions.

Pyrromethene refers to a class of organic compounds that are characterized by a structure consisting of a pyrrole moiety bonded to a methylene group. These compounds are often used as dyes or fluorescent labels due to their unique photophysical properties. Pyrromethenes can exhibit strong fluorescence and are of interest in various applications including in the development of laser dyes, sensors, and in the field of fluorescence microscopy.

Laser gain media, also known simply as gain media, refers to the material within a laser that amplifies light through stimulated emission. When energy is supplied to this medium (typically through electrical or optical pumping), it gets excited to higher energy states. When these excited atoms or molecules return to their lower energy states, they emit photons, which can then stimulate further emissions in a process known as stimulated emission.

GRENOUILLE can refer to a few different things, depending on the context. In general, the term "grenouille" is French for "frog." However, in literature, it is often associated with the character Jean-Baptiste Grenouille from the novel "Perfume: The Story of a Murderer" by Patrick Süskind.

"The Invisible Woman" is a 1940 American science fiction comedy film produced by Universal Pictures. It was directed by Edward Sutherland and is part of Universal's series of films featuring classic monsters, though it takes a lighter, comedic approach compared to other entries in the genre. The film tells the story of a beautiful woman named Kitty Carroll, played by Virginia Bruce, who is selected to become invisible in an experiment conducted by a scientist, Professor Gibbs, portrayed by John Barrymore.

"The Fabric of the Cosmos" is a popular science book written by physicist Brian Greene, published in 2004. The book explores fundamental concepts in physics, particularly in the realms of space, time, and the nature of the universe. Greene discusses complex topics such as the theory of relativity, quantum mechanics, and string theory, presenting them in a way that is accessible to a general audience.

Fiction involving wormholes often explores themes of time travel, parallel universes, and the nature of space itself. Here are some notable examples across various mediums: 1. **Literature**: - **"The Forever War" by Joe Haldeman**: This military science fiction novel uses time dilation caused by relativistic space travel, which can be conceptually linked to wormholes, to explore the effects of time on soldiers returning from distant battles.

The term "inertialess drive" refers to a hypothetical propulsion system that would allow a spacecraft or vehicle to move without the constraints of inertia. Inertia is the property of matter that causes it to resist changes in its state of motion; in classical physics, this means that a significant amount of force (energy) is required to change an object's velocity.

"The Dosadi Experiment" is a science fiction novel by Frank Herbert, published in 1965. The story is set on the planet Dosadi, which is isolated from the outside universe by a force field. The inhabitants of Dosadi include both human settlers and a native alien species known as the Kowulu. The planet presents a harsh environment, which has led to a unique adaptation of its inhabitants and the development of a society with its own complexities.

In Dungeons & Dragons (D&D), magic is a central element of the game's fantasy setting, encompassing a wide range of supernatural abilities, spells, and effects that characters can wield or encounter. Here are some key aspects of magic in D&D: 1. **Spells**: Characters, particularly spellcasters such as wizards, sorcerers, clerics, druids, and warlocks, can cast spells, which are magical effects with specific rules and outcomes.

The term "Simple Magnetic Overunity Toy" typically refers to a concept or device that allegedly demonstrates overunity, which is a term used in the context of energy systems that supposedly produce more energy output than input. These devices often claim to use magnets in a way that seemingly allows them to operate indefinitely without a net energy loss, defying established laws of physics, particularly the First and Second Laws of Thermodynamics.
