The Uragan-2M is a type of multiple rocket launcher developed by Ukraine. It is a modernized version of the earlier Uragan (Hurricane) system, which was originally designed and produced during the Soviet era. The Uragan-2M system is capable of launching a variety of rockets and is designed for long-range artillery support.
The 6N14P is a type of vacuum tube (or thermionic valve) commonly used in audio equipment and various electronic applications. It is a Russian designation for a specific type of dual triode tube, where "6N" indicates that it requires a 6-volt heater voltage, and "14P" refers to its particular design and characteristics.
Abduhamid Juraev is likely a reference to a specific individual, but without additional context, it is difficult to provide concrete information. If you are referring to a person in a specific field, such as politics, sports, academia, etc.
The mole is a fundamental unit in chemistry used to quantify the amount of substance. It is one of the seven base units in the International System of Units (SI). One mole is defined as exactly \(6.02214076 \times 10^{23}\) entities, which could be atoms, molecules, ions, or other particles. This number is known as Avogadro's number.
Abhyankar's inequality is a result in algebraic geometry and algebra that provides a bound on the number of branches of a curve at a certain point in relation to its singularities. More precisely, it deals with the relationship between the degree of a polynomial and the number of points at which the curve may be singular except for a specified set.
Abraham Fraenkel was a notable mathematician, best known for his contributions to set theory. He was one of the developers of the Zermelo-Fraenkel axioms (ZF), which are foundational axioms for set theory and form the basis for much of modern mathematics.
Abstention generally refers to the act of refraining from participating in a particular activity or decision. The term can have different meanings depending on the context in which it is used: 1. **Political Voting**: In the context of voting, abstention describes the choice of an individual or group to not cast a vote. This can happen for various reasons, including disapproval of the options presented, a lack of interest, or a desire not to influence the outcome.
The abundance of elements in the Earth's crust varies significantly, with certain elements being much more prevalent than others. Here is a list of some of the most abundant elements found in the Earth's crust, typically expressed in weight percent (%): 1. **Oxygen (O)** - ~46.6% 2. **Silicon (Si)** - ~27.7% 3. **Aluminum (Al)** - ~8.1% 4. **Iron (Fe)** - ~5.
Actor-Network Theory (ANT) is a theoretical and methodological approach in social science and sociology that emphasizes the relationships and interactions between different actors (both human and non-human) in the construction of social phenomena. Developed primarily by scholars like Bruno Latour, Michel Callon, and John Law in the 1980s, ANT challenges traditional distinctions between the social and the technical, as well as between humans and non-humans.
A cubic mile of oil is a volumetric measurement used to quantify large amounts of oil. One cubic mile is equal to approximately 4.168 trillion gallons or about 15.85 trillion liters. When referring to oil, this measurement is often used to discuss reserves or production capacity on a large scale, such as when assessing the extent of oil deposits in a geographic area or the amount of oil that can be produced over time.
Adjacent Channel Power Ratio (ACPR) is a measure used in telecommunications to assess the level of interference between adjacent frequency channels in a communication system. It quantifies the level of power that is present in adjacent channels compared to the power in the desired channel. ACPR is typically expressed in decibels (dB) and is important for ensuring the quality of communication and compliance with regulatory standards.
As of my last knowledge update in October 2023, "Advance And Secure" doesn't refer to a widely recognized concept, brand, or terminology within public knowledge. It could be a phrase used in various contexts such as security measures, technology advancements, or even a specific organizational program.
Affection Exchange Theory (AET) is a communication theory that suggests affection is a fundamental human need and plays a crucial role in the development and maintenance of interpersonal relationships. Developed primarily by Dr. Kory Floyd, the theory posits that the expression and receipt of affection can lead to various positive outcomes, such as improved mental and physical health, increased relational satisfaction, and enhanced emotional well-being.
Aglaonice, also spelled Aglaonike or Aglaonice, is a figure from ancient Greek mythology, often associated with the field of astronomy and the knowledge of lunar phases. She is sometimes described as a witch or a sorceress and is credited with the ability to eclipse the moon or predict lunar events.
The Ahlswede–Daykin inequality is a result in information theory that relates to the concept of entropy and the joint distribution of random variables. It provides a connection between the joint entropy of a set of variables and the individual entropies of those variables, specifically in the context of entropy in multiple dimensions. To give a brief overview, let \( X \) and \( Y \) be two discrete random variables with joint distribution.
The Gabriel–Rosenberg reconstruction theorem is a result in the field of category theory and algebraic geometry, particularly concerning the reconstruction of schemes or algebraic varieties from their categories of coherent sheaves. The theorem, often associated with the work of Gabriel and Rosenberg, deals with the relationship between a certain type of category, called a quasi-coherent sheaf category, and the underlying geometric objects (in this case, schemes).
Alexander Balankin is a prominent figure known for his contributions to various scientific fields, particularly in the areas of materials science, mechanics, and non-linear dynamics. He is often associated with research involving fractals, complex systems, and the development of advanced materials with unique properties. Balankin has published numerous papers and has been involved in academia, contributing to a better understanding of the physical principles underlying material behavior and structural integrity.
Alice Archenhold does not appear to be a widely recognized figure or term in publicly available information up to October 2023. It's possible that she could be a private individual, a lesser-known personality, or a fictional character.
Alinaghi Khamoushi is an Iranian political figure known for his involvement in the political landscape of Iran, particularly during the post-revolutionary period. He has been associated with various reformist movements and has held positions in the Iranian government and political institutions.

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.
