Actancy is a concept in linguistics and semiotics that refers to the role and function of entities within a narrative or communicative framework. It is primarily concerned with how agents (who perform actions) and patients (who receive or are affected by actions) are structured within a text or discourse. The term is often associated with the work of scholars like Greimas, who explored how various participants in a narrative interact and how their relationships shape the meaning of a story.
A polar low is a type of small, intense, cyclonic storm that occurs in polar and subpolar regions, typically over the ocean. These weather systems are characterized by low pressure, strong winds, and often significant precipitation, usually in the form of snow or rain. Polar lows can develop quickly and are most commonly found in areas such as the Arctic, Antarctic, and the surrounding seas during the winter months when the temperature contrasts between the cold land or sea ice and relatively warmer ocean waters are greatest.
Tribotronics is a field that combines tribology (the study of friction, wear, and lubrication) with electronics. This interdisciplinary area focuses on the development of electronic devices that can monitor and interact with tribological processes. By integrating sensors and electronic components with traditional tribological systems, tribotronics can enhance the performance and efficiency of mechanical systems.
As of my last knowledge update in October 2021, Tasneem M. Shah may not be a widely recognized public figure or entity. If you're referring to a specific person, organization, or topic that has gained prominence after that date, I would not have that information.
Christian Thomasius (1655–1728) was a German philosopher, lawyer, and publicist, known for his contributions to the development of modern legal and philosophical thought. He is often recognized as one of the key figures in the early Enlightenment period, particularly in Germany. Thomasius is best known for advocating the separation of law and morality, which was a significant departure from the views of earlier scholars who often conflated the two.
VCDIFF (Variable Length Codestreams for Data Interchange Format) is a format and protocol used for data compression and transfer, primarily designed for efficiently transmitting binary data over networks. It is particularly useful for scenarios where only small changes or updates to existing data need to be sent, rather than retransmitting entire datasets.
Walter H. Barkas (1912-1991) was an American photographer known for his work documenting the American jazz scene and various cultural events. His photography often captured the essence of musical performances and the vibrant atmosphere of the jazz community, particularly in the mid-20th century. Barkas's work has been featured in various publications, exhibitions, and is recognized for its historical importance in preserving moments from an influential era in music history.
The Born-Haber cycle is a thermodynamic cycle used to understand the formation of ionic compounds from their elements by breaking down the lattice energy into individual steps. It provides a systematic approach to calculating lattice energy, which is the energy released when gaseous ions combine to form an ionic solid. The cycle relates various types of energy changes involved in the formation of an ionic compound.
As of my last knowledge update in October 2021, there is no widely recognized public figure by the name of Vladimir Neuvazhaev. If he has gained significance or notoriety after that date, or if he is a figure known in specific niche circles, I wouldn't have information on him.
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.
"Philipp Carl" could refer to different subjects depending on the context. It might be a name of a person, possibly a historical figure, artist, or a contemporary individual. It could also refer to a place, product, or brand. Without additional context, it's challenging to provide a specific answer.
FORMAC, which stands for Formal Mathematical Computation, is a programming language and system designed for symbolic computation and formal reasoning in mathematics. It provides tools for manipulating mathematical expressions, performing algebraic operations, and solving equations symbolically. The primary goal of FORMAC is to facilitate the development of algorithms and software systems that can handle complex mathematical manipulations easily.
"Philosophiæ Naturalis Principia Mathematica," commonly referred to as the "Principia," is a seminal work in the field of physics and mathematics written by Sir Isaac Newton. First published in 1687, the Principia lays the groundwork for classical mechanics and describes Newton's laws of motion and universal gravitation. In the book, Newton presents a comprehensive framework for understanding the motion of celestial bodies and the forces that act upon them, using mathematical formulations.
The Transformation Priority Premise (TPP) is a principle from deontic logic, which is a branch of logic that deals with duty, permission, and related concepts. Specifically, the TPP addresses the relationship between obligations and the potential for transforming those obligations into actions or outcomes. The essence of the Transformation Priority Premise is that if a certain action is obligated, then it is prioritized over other actions or obligations that may conflict with it.
Francis Eugene Nipher (1851–1926) was an American physicist and inventor, known for his contributions to the field of physics, particularly in the study of electromagnetism and optics. He is also recognized for his work in educational reform and for being an advocate for the importance of scientific research. Nipher made several important contributions during his career, and he held academic positions, including being a professor at Washington University in St. Louis.
A phytotron is a controlled environment facility designed for studying plant growth under various environmental conditions. It typically allows researchers to manipulate variables such as temperature, humidity, light intensity, and carbon dioxide levels, providing a consistent and replicable setting to investigate the effects of these factors on plant development, physiology, and responses to stress factors.
Pierre Macq appears to refer to a specific individual rather than a widely recognized concept or entity. Without more context, it could pertain to anyone named Pierre Macq, such as a professional in a certain field, an artist, or perhaps a historical figure.

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.
