Proline isomerization refers to the process by which the peptide bond involving the amino acid proline can exist in either a cis or trans configuration. This is particularly relevant in the context of protein structure and function, as the isomerization can influence protein folding, stability, and interactions. In epigenetics, proline isomerization can play a role in the regulation of chromatin structure and gene expression.
Enantiomeric excess (ee) is a measure of the purity of a chiral compound in terms of the proportion of one enantiomer relative to the other. Enantiomers are pairs of molecules that are non-superimposable mirror images of each other, and they often differ in their biological activity and properties.
The Fürst-Plattner Rule is a guideline used in mineral processing, particularly in the context of determining the viability of extracting metals from ore. It specifically relates to the extraction of silver from silver-bearing ores, although its principles can sometimes be applied to other metals as well. The rule suggests that the value of the metal that can be extracted must exceed the cost of recovering it, including expenses related to mining, milling, and refining the ore.
The ligand cone angle is a concept used in coordination chemistry to describe the spatial orientation of ligands around a central metal ion in a coordination complex. It refers to the geometric representation of how ligands are arranged and the degree to which they can approach and interact with the central metal atom.
Pseudorotation is a term used in chemistry and molecular physics to describe a specific type of conformational change in certain cyclic compounds, particularly in the context of five-membered rings or certain larger rings. It involves the movement of atoms within the molecule that allows the structure to rotate around a particular axis, leading to a change in the arrangement of atoms or groups attached to the ring without breaking any bonds.
The biosphere is the global sum of all ecosystems, representing the zone of life on Earth. It includes all living organisms, including plants, animals, and microorganisms, as well as the environments in which they interact. The biosphere is characterized by the interactions between these organisms and their physical surroundings, including the atmosphere (air), hydrosphere (water), and lithosphere (land).
The stereoelectronic effect refers to the influence of molecular geometry on electronic interactions and reactivity, particularly in the context of chemical bonding and reaction mechanisms. It describes how the spatial arrangement of atoms and the orientation of orbitals can affect the electronic properties of a molecule and, consequently, its reactivity. In essence, the stereoelectronic effect highlights the relationship between the arrangement of bonds in three-dimensional space and the electron distribution in molecular orbitals.
Syn and anti addition refer to the specific orientations of the addition of reactants across a double bond in organic molecules. These terms are especially important in the context of stereochemistry, the study of the three-dimensional arrangements of atoms within molecules. 1. **Syn Addition**: - In syn addition, the two substituents are added to the same side (or face) of the double bond.
The Paley-Wiener integral is a mathematical concept used primarily in the field of signal processing and Fourier analysis. It is associated with the analysis of functions that are band-limited, meaning that they contain no frequencies higher than a certain maximum frequency. The Paley-Wiener integral is particularly important in the study of the properties of these functions in relation to the Fourier transform.
The Reflection Principle is a fundamental concept in the study of stochastic processes, particularly in the context of the Wiener process (also known as Brownian motion). The principle provides a method for analyzing the behavior of Brownian paths, especially concerning their maximum or minimum values.
"De Constantia" is a philosophical work written by the Dutch philosopher and statesman Hugo Grotius, who is often considered one of the founding figures of international law. The work, titled "De Constantia," translates to "On Constancy" in English, and it was written in 1620, at a time when Grotius was in exile.
Epoché is a philosophical term that originates from ancient Greek, meaning "suspension" or "bracketing." It is primarily associated with the discipline of phenomenology, particularly in the works of the German philosopher Edmund Husserl. In phenomenology, Epoché refers to the practice of suspending judgment about the natural world and our preconceived notions to focus on our immediate experiences and perceptions.
Oikeiôsis is a philosophical concept from ancient Stoicism that refers to the process of recognizing what is natural and appropriate to oneself and one's role in the world. The term is often translated as "appropriation" or "familiarization," and it encompasses the idea of developing an understanding and attachment to one's own nature, as well as to one’s family, community, and humanity at large. In Stoic thought, oikeiôsis is an essential part of ethical development.
In Stoic philosophy, "passions" (or "passiones" in Latin and "pathē" in Greek) refer to intense emotions or feelings that can disrupt rational thought and lead to irrational behavior. Stoics differentiate between "passions" and "virtue" or "rational emotional responses." Stoic philosophers, like Seneca, Epictetus, and Marcus Aurelius, believed that passions often arise from incorrect judgments about what is good or bad.
Stoic physics is an integral part of Stoic philosophy, which originated in ancient Greece and Rome. The Stoics, including key figures such as Zeno of Citium, Cleanthes, and later thinkers like Seneca and Marcus Aurelius, developed a comprehensive system of thought that encompassed ethics, logic, and physics. In Stoic thought, physics refers not just to the study of the natural world, but also to the underlying principles that govern the universe.
In physics, particularly in the fields of particle physics, quantum field theory, and statistical mechanics, a coupling constant is a parameter that determines the strength of an interaction or force between particles or fields. It essentially quantifies how strongly a particle interacts with others or with a field.
"Russian string theorists" generally refers to a group of physicists from Russia who specialize in string theory, a theoretical framework in physics that attempts to reconcile general relativity and quantum mechanics. String theory posits that the fundamental building blocks of the universe are not point particles but rather one-dimensional objects called "strings." These strings vibrate at different frequencies and can manifest as different particles, such as quarks and electrons.
Erica Ollmann Saphire is a prominent American scientist and researcher known for her work in the field of virology, particularly in studying viral infections and the immune system's responses. She has focused on viruses such as Ebola and other pathogens, exploring how they interact with the immune system and developing potential therapeutic strategies. Saphire is affiliated with institutions such as the Scripps Research Institute, where she conducts research aimed at understanding viral mechanisms and advancing vaccine development.
As of my last knowledge update in October 2023, there is no widely recognized organization or entity known as the "British Institutions Reflection Profiling Syndicate." It's possible that it could be a niche group, a fictional concept, an acronym, or a newly established organization that has emerged since my last update.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
