A fluorescent lamp is a type of electric light that works by passing an electric current through a gas, which emits ultraviolet light. This ultraviolet light then excites a phosphor coating on the inside of the glass tube, causing it to emit visible light. Fluorescent lamps are commonly used in various applications due to their energy efficiency and longer lifespan compared to traditional incandescent bulbs.
Fluorescent lamps are a type of electric lamp that produces light by the excitation of gas. They work by passing an electric current through a gas (typically argon or neon) which produces ultraviolet (UV) light. This UV light then interacts with a phosphor coating on the inside of the lamp, causing it to emit visible light. Fluorescent lamps are widely used for their energy efficiency and longer lifespans compared to incandescent lamps.
A germicidal lamp is a type of ultraviolet (UV) lamp that emits UV-C light, which has wavelengths typically between 200 and 280 nanometers. This UV-C light is effective at disinfecting surfaces, air, and water by killing or inactivating microorganisms such as bacteria, viruses, and fungi. Germicidal lamps are commonly used in various applications including: 1. **Healthcare Settings**: To sterilize operating rooms, patient rooms, and medical equipment.
A Teltron tube is a type of specialized glass vacuum tube used in educational and experimental physics to demonstrate various principles, particularly in the field of electricity and magnetism. These tubes typically contain low-pressure gases, which become ionized when a high voltage is applied across electrodes within the tube. As a result, visible cathode rays (or electron streams) are produced, allowing students and researchers to observe phenomena such as the behavior of electrons in electric and magnetic fields.
A list of sulfur lamp installations would typically refer to locations or instances where sulfur lamps, which are high-intensity light sources, are used. These lamps emit light by passing an electric current through sulfur vapor, creating a bright source of illumination that is often used in various applications such as outdoor lighting, streetlights, and specialized industrial uses. However, detailed lists of specific installations could vary widely and might not be readily available in public domains.
Low-pressure discharge refers to a type of gas discharge where the pressure within the discharge system is relatively low. This phenomenon occurs in various contexts, such as in the functioning of certain types of gas discharge lamps, plasma sources, and other electrical discharge devices. In low-pressure discharge systems, the gas atoms or molecules are spaced farther apart than in higher-pressure environments, allowing them to be ionized more easily when an electric field is applied.
Luminous discharge tubes are devices that produce light through electrical discharge in a gas-filled tube. These tubes typically contain low-pressure gas, such as neon, argon, or other noble gases, which emit light when an electrical current is passed through them. The light is produced as electrons collide with the gas atoms, exciting them and causing them to release photons when they return to their ground state.
The factorial moment generating function (FMGF) is a generating function that is particularly useful in probability and statistics for dealing with discrete random variables, especially those that take non-negative integer values. The FMGF is closely related to the moments of a random variable but is structured in a way that makes it suitable for analyzing distributions where counts or frequencies are relevant, like the Poisson distribution or the negative binomial distribution.
U-HID (Universal Human Interface Device) is a term that typically refers to a type of device or technology designed for various human-computer interaction purposes. It usually encompasses devices that facilitate input from users, making it easier for them to interact with computers or other digital interfaces. The U-HID could refer to various forms of input devices such as keyboards, mice, touchscreens, or specialized hardware used in gaming, assistive technology, or even custom user interfaces for specific applications.
An Ultra-high-performance lamp, often referred to as UHP lamp, is a type of high-intensity discharge (HID) lamp that is primarily used in advanced projectors, especially in home cinema, commercial projection, and some specialized lighting applications. UHP lamps are known for their high brightness, excellent color rendering, and relatively long life compared to other types of bulbs.
The Yablochkov candle, named after Russian electrical engineer Pavel Yablochkov, was an early form of electric arc lamp used for street lighting and other applications in the late 19th century. Developed around 1878, the Yablochkov candle consists of two carbon electrodes placed parallel to each other, separated by a thin insulating material, and encased in a cylindrical glass envelope. When an electric current passes through the electrodes, an arc forms between them, producing light.
Edible gels are a type of food product made from gelling agents that create a gel-like texture. They are commonly used in the food industry for various applications, including as thickening agents, stabilizers, or for creating desserts and confections. Some common gelling agents used to produce edible gels include: 1. **Gelatin**: A protein derived from animal collagen, used in a variety of sweets like gummy candies, marshmallows, and jellies.
Aluminum chloride hexahydrate, with the chemical formula AlCl₃·6H₂O, is a hydrated form of aluminum chloride. It consists of one aluminum ion (Al³⁺) and three chloride ions (Cl⁻), combined with six water molecules. This compound is typically a white or colorless crystalline solid. ### Properties: - **Molecular Weight:** Approximately 241.
Gelatin is a translucent, flavorless food ingredient derived from collagen, which is a protein found in animal connective tissues, such as skin, bones, and cartilage. It is commonly used in cooking and food production due to its gelling properties.
The triangle inequalities are fundamental properties of triangles related to the lengths of their sides. They state that, for any triangle with sides of lengths \(a\), \(b\), and \(c\), the following inequalities must hold: 1. \(a + b > c\) 2. \(a + c > b\) 3.
Gelclair is a topical medication typically used to relieve oral mucositis, which is an inflammation and ulceration of the mucous membranes in the mouth. This condition can occur as a side effect of chemotherapy, radiation therapy, or other treatments. Gelclair is formulated as a gel that provides a protective coating over the oral mucosa, helping to soothe pain and discomfort, promote healing, and reduce inflammation.
Hantz reactions, also known as Hantzsch reactions, refer to a series of chemical reactions that involve the synthesis of dihydropyridines. These reactions are named after the German chemist Heinrich Hantzsch, who developed the method. In its most common form, the Hantzsch reaction involves the condensation of aldehydes (or ketones), β-ketoesters (or certain other carbonyl compounds), and ammonia or primary amines in the presence of a reducing agent.
Low molecular-mass organic gelators (LMOGs) are small organic molecules that can form gel-like structures when dispersed in a solvent at relatively low concentrations. Unlike traditional polymeric gelators, LMOGs typically have a molecular weight of less than 1,000 Da and can self-assemble into fibrillar or network structures that trap solvent molecules, leading to the formation of a gel.
Organogels are a type of gel-like material composed primarily of a liquid organic solvent and a gelator, which is typically a small organic molecule or polymer that can form a three-dimensional network throughout the solvent. This network holds the solvent in place, giving the material its gel-like properties.
Sergey Krasnikov may refer to multiple individuals, but one prominent figure by this name is a Russian scientist known for his work in the field of theoretical physics, particularly in areas such as quantum mechanics and related disciplines.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
