As of my last update in October 2023, "StegoShare" may not refer to a widely recognized or specific concept, product, or service that I am aware of. However, it seems to suggest a combination of "steganography" (the practice of hiding information within other non-secret text or data) and "sharing," which could imply a platform or tool aimed at securely sharing information using steganographic techniques.
Steganographia is the practice of concealing messages within other non-secret text or data to avoid detection. The term is often associated with the specific art and craft of hidden communications, where information is embedded in a way that makes it difficult for an observer to realize that a message is present. Historically, the term "Steganographia" was popularized by Johannes Trithemius, a 15th-century monk, who wrote a book of the same name.
The Steklov Institute of Mathematics, part of the Russian Academy of Sciences, consists of a diverse group of academic staff, including mathematicians and researchers specializing in various fields of mathematics. The institute is known for its contributions to pure and applied mathematics, and its faculty often includes leading experts in areas like algebra, topology, mathematical physics, and more.

The Minoru 3D Webcam can be used with various software applications that support 3D video and can work with common operating systems.
Bredt's rule is a guideline in organic chemistry that relates to the structure of certain bicyclic compounds, particularly those containing a double bond in a bridgehead position. The rule states that: **In bicyclic compounds, a double bond cannot be formed at the bridgehead atoms (the atoms at the ends of the bridges connecting two cycles) unless the bridgehead is part of a ring containing more than four atoms.
Endo-exo isomerism is a type of stereoisomerism that occurs in certain bicyclic compounds, particularly those containing bridgehead atoms. The terms "endo" and "exo" refer to the spatial arrangement of substituents relative to the plane of the bicyclic structure. In this context: - **Endo isomer**: In the endo configuration, substituents (e.g.
Torquoselectivity refers to the preference of a chemical reaction to generate a specific stereochemical outcome based on the torque or twisting forces that drive the interaction of reactants. This concept is particularly relevant in the context of asymmetric synthesis and organocatalysis, where the spatial arrangement of atoms in a molecule plays a critical role in determining the product formed.
Chiral resolution, also known as enantiomeric resolution, is the process of separating a racemic mixture (a mixture that contains equal amounts of enantiomers) into its individual enantiomers. Enantiomers are molecules that are non-superimposable mirror images of each other, much like left and right hands.
Chiral thin-layer chromatography (chiral TLC) is an analytical technique used to separate enantiomers or chiral compounds based on their optical activity. This method is particularly important in fields such as pharmaceuticals, where the enantiomeric forms of a compound can exhibit different biological activities or pharmacological effects. ### Key Features of Chiral TLC: 1. **Chirality**: Chiral compounds are molecules that exist in two non-superimposable mirror-image forms, known as enantiomers.
A Fischer projection is a two-dimensional representation of a three-dimensional organic molecule, specifically used for depicting the stereochemistry of carbohydrates and amino acids. It was developed by Emil Fischer in the early 20th century. In a Fischer projection, the molecule is represented as a vertical and horizontal arrangement of bonds. The vertical lines represent bonds that project away from the viewer (into the plane of the paper), while the horizontal lines represent bonds that project towards the viewer (out of the plane of the paper).
A Haworth projection is a method for representing the cyclic structures of sugars (carbohydrates) in a two-dimensional form while keeping their three-dimensional stereochemistry in mind.
Hexol is a brand name for a type of solvent that is primarily composed of a mixture of hydrocarbons. It is used in various industrial applications, including cleaning, degreasing, and as a paint thinner. Hexol is capable of dissolving greases, oils, and other substances, making it useful in maintenance and manufacturing processes. In particular, it may refer to specific formulations that are designed for particular uses, such as in automotive or industrial settings.
The cryosphere refers to the frozen water part of the Earth’s system, encompassing all forms of ice and snow. This includes glaciers, ice caps, ice sheets, sea ice, permafrost, and seasonal snow cover. The cryosphere plays a crucial role in the Earth's climate system and influences global sea levels, weather patterns, and ecosystems.
Specific rotation is a physical property of optically active substances that measures the degree to which a compound can rotate the plane of polarized light. It is particularly important in the study of chiral molecules, such as many organic compounds and certain biomolecules.
The Natta projection is a stereochemical representation used to depict the three-dimensional arrangement of atoms in a polymer's repeating unit, particularly in the context of polymer chemistry where stereochemistry plays a significant role. Specifically, it is often associated with the structure of isotactic polypropylene, which is a type of polypropylene where all the methyl groups (–CH3) are arranged on the same side of the polymer chain.
A Newman projection is a way of visualizing the three-dimensional (3D) structure of organic molecules, particularly alkanes, in a two-dimensional (2D) format. It allows chemists to analyze the spatial arrangement of atoms and bonds around a specific bond between two carbon atoms. In a Newman projection, one looks straight down the axis of a particular bond (usually a carbon-carbon bond).
Noyori asymmetric hydrogenation is a chemical reaction developed by Japanese chemist Ryoji Noyori, which allows for the selective hydrogenation of prochiral ketones and other similar compounds to produce enantiomerically enriched alcohols. This reaction is particularly significant in the field of asymmetric synthesis, where the goal is to produce one specific enantiomer of a chiral product over the other.
P-Chiral phosphines are a class of chiral ligands that are characterized by the presence of a phosphorus atom that is stereogenic (chiral). This means that the phosphorus center can exist in two non-superimposable mirror image forms, leading to different spatial arrangements of substituents attached to the phosphorus atom. In the context of coordination chemistry and catalysis, P-chiral phosphines are particularly valuable because they can impart stereochemical information to reactions, thereby enabling asymmetric synthesis.
Protein primary structure refers to the unique sequence of amino acids that make up a protein. This sequence is determined by the genetic code and is crucial because it ultimately dictates how the protein will fold and function. Amino acids are linked together by peptide bonds to form a polypeptide chain, and the order of these amino acids is specified by the mRNA sequence during translation.
Pyramidal inversion is a phenomenon that occurs in certain molecules where the configuration of a chiral center can interconvert between two different arrangements. Specifically, this term is often used in the context of molecules that adopt a pyramidal geometry at a nitrogen or phosphorus atom. In a pyramidal structure, the central atom is bonded to three other atoms or groups in a manner that gives it a trigonal pyramidal shape, resembling a pyramid.

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.
