Unix System Laboratories (USL) was a company that played a significant role in the development and commercialization of the Unix operating system. Originally established by AT&T in 1988, USL was intended to manage and promote Unix as both a commercial product and a standard for operating systems. Here are some key points about Unix System Laboratories: 1. **Origin**: The company was formed as a spin-off from AT&T's Bell Laboratories, where Unix was originally developed.
A vacuum furnace is a type of furnace that operates under a vacuum or controlled atmospheric conditions, which helps to prevent oxidation and contamination of the materials being processed. These furnaces are commonly used in various industrial applications, including metal processing, sintering, brazing, and heat treatment. ### Key Features of Vacuum Furnaces: 1. **Vacuum Environment**: The primary characteristic is its ability to create a vacuum or a controlled atmosphere (such as inert gases) around the workpiece.
Transit-oriented developments (TOD) are urban planning and design strategies that focus on creating compact, walkable communities centered around high-quality public transportation systems. The primary goal of TOD is to maximize access to public transit, reduce reliance on cars, and promote sustainable development patterns.
As of my last knowledge update in October 2023, there isn't a widely known figure by the name of Bobomurat Ahmedov. It's possible that he may be a local figure, a professional in a specific field, or someone who has gained prominence in recent events after my last update.
Thermos LLC is a company best known for its vacuum-insulated containers, including bottles, flasks, and food storage solutions. Founded in 1904, Thermos pioneered the use of vacuum insulation technology, which helps maintain the temperature of hot and cold liquids for extended periods. The brand is synonymous with durable and portable drinkware and food containers designed for both everyday use and outdoor activities.
A hot-filament ionization gauge (HFIG) is a type of vacuum gauge used to measure low pressures, typically in the range of 10^-3 to 10^-9 torr (or mbar). It operates based on the principle of ionization created by a hot filament, which serves as the electron source.
A "bell jar" is a closed glass jar that is often used in scientific experiments and demonstrations. It can create a vacuum when placed over an object and the air is removed, enabling various experiments related to air pressure, gas behavior, or demonstrating principles of physics. In a broader context, the term "bell jar" is also associated with Sylvia Plath's semi-autobiographical novel "The Bell Jar," published in 1963.
A cold trap is a device used in various scientific and industrial applications to capture and condense volatile substances, usually gases or vapors, by cooling them to a point where they transition into a liquid or solid state. Cold traps are commonly used in vacuum systems, refrigeration, and cryogenics to prevent unwanted vapors from entering pumps or other equipment.
The term "25L6" could refer to a few different things depending on the context, but it most commonly refers to a type of vacuum tube. The 25L6 is a beam power tube that was widely used in audio amplification and radio applications, particularly in the mid-20th century. It is known for its application in consumer electronics, such as radios and amplifiers.
The 6L6 is a type of vacuum tube (electron tube or thermionic valve) that is used primarily in audio amplification and signal processing applications, especially in guitar amplifiers and hi-fi audio equipment. It was developed in the 1930s by RCA and has become one of the most popular power tubes in the music industry.
A Field Emitter Array (FEA) is a type of electron emitter technology that utilizes a densely packed array of nanoscale field emitters to produce electrons for various applications, primarily in vacuum devices and electronic components. The key principle behind FEAs is the phenomenon of field emission, whereby electrons are emitted from a sharp tip (or an array of tips) when subjected to a strong electric field.
Aquadag is a colloidal graphite suspension used primarily as a conductive coating for various applications, particularly in the field of electronics and materials science. It is often employed to create a conductive layer on non-conductive surfaces or to enhance the conductivity of certain materials. Key features of Aquadag include: - **Composition**: It typically consists of finely divided graphite particles suspended in water, which gives it both conductive and protective properties.
Audion is a software application that was originally developed for macOS as an audio player and streaming client, created by the company Known as Panic. It gained popularity in the late 1990s and early 2000s for its ability to handle various audio formats and for its user-friendly interface. Audion was known for its support of internet radio streaming, allowing users to listen to live broadcasts.
The EL84 is a vacuum tube (also known as a valve) that is commonly used in audio amplification, particularly in guitar amplifiers and hi-fi audio equipment. It is a glass pentode tube that was first introduced by Philips in the late 1950s and has since become popular due to its warm sound and efficiency.
The KT66 is a type of vacuum tube (or valve) that was first developed in the 1940s by the British company, GEC (General Electric Company). It is a beam tetrode, which is a type of electron tube that is commonly used in audio amplification applications, particularly in guitar amplifiers and hi-fi audio equipment.
Concurrent validity is a type of validity used to assess the effectiveness of a test or measurement tool by comparing its results with those of a well-established criterion or benchmark that is measured at the same time. In other words, it evaluates how well one measure correlates with another measure that is considered to be a valid indicator of the same construct. To establish concurrent validity, researchers typically: 1. **Select a new test or instrument**: This is the measure whose validity is being evaluated.
La Compagnie des Lampes is a French company known for specializing in lighting products, especially decorative lamps and fixtures. Typically, they offer a wide range of styles, from traditional to modern designs, catering to various interior aesthetics. The brand focuses on craftsmanship and quality, often using materials like glass, metal, and wood to create unique lighting solutions. In addition to decorative lamps, they may provide custom lighting solutions and a selection of complementary home decor items.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
