RNA CoSSMos (RNA Comparative Sequence Structure Models) is a computational method used in bioinformatics to predict the secondary structure of RNA sequences. It typically utilizes comparative genomics techniques, where the sequences of related RNA molecules from different species are analyzed to infer structural features. By aligning these sequences, RNA CoSSMos can identify conserved regions and structural motifs that are likely to play important roles in the RNA's function.
The "ring flip" is a conformational change that occurs in cyclic compounds, particularly in cyclohexane and its derivatives. This phenomenon is important in organic chemistry as it affects the physical properties and reactivity of the molecule. In the case of cyclohexane, the ring flip involves the conversion of one chair conformation to another. Cyclohexane can exist in two primary stable conformations known as "chair" conformations.
Tetrahedral molecular geometry is a three-dimensional arrangement of atoms in which a central atom is bonded to four other atoms positioned at the corners of a tetrahedron. This geometry is characterized by bond angles of approximately 109.5 degrees. The tetrahedral shape results from the repulsion between electron pairs around the central atom, which is often carbon or a similar atom with four bonding sites.
Trigonal planar molecular geometry is a type of molecular shape that occurs when a central atom is surrounded by three other atoms, all positioned at the corners of an equilateral triangle. This arrangement results in a bond angle of approximately 120 degrees between the atoms. The trigonal planar shape is typically found in molecules where the central atom has three bonding pairs of electrons and no lone pairs. An example of a molecule with trigonal planar geometry is boron trifluoride (BF₃).
"Russian nuclear physicists" refers to scientists and researchers in Russia who specialize in the field of nuclear physics. This branch of physics deals with the properties and behavior of atomic nuclei, including the forces that hold them together, the reactions that occur during nuclear interactions, and the applications of nuclear energy, among other topics. Russian nuclear physicists have been influential in the development of various nuclear technologies, including nuclear power generation, nuclear medicine, and even nuclear weapons research.
“Russian plasma physicists” refers to scientists and researchers in Russia who specialize in the study of plasma physics. Plasma physics is a branch of physics that deals with the behavior of ionized gases, or plasmas, which are often referred to as the fourth state of matter (after solid, liquid, and gas). In a plasma, a significant number of atoms are ionized, leading to unique electromagnetic properties and behavior.
Alexey Alexandrov could refer to multiple individuals, as it is a relatively common name. Without more context, it's difficult to pinpoint exactly which Alexey Alexandrov you are referring to. For instance, it could be a reference to: 1. **A scientist or academic**: There may be notable individuals with that name in fields such as physics, mathematics, or other areas of research.
Constantin Perskyi was a pioneering figure in the field of telecommunications and is notably recognized for his contributions to the development of television technology. He is often credited with coining the term "television" in the early 20th century. Perskyi was an engineer and inventor, and he played a significant role in the theoretical and practical aspects of electronic communication. His work helped lay the foundation for later advancements in broadcasting and visual media.
The term "Alpha effect" can refer to different concepts depending on the context. Here are a few predominant uses of the term: 1. **Finance and Investments**: In finance, the Alpha effect relates to the performance of an investment relative to a benchmark index, usually in the context of active portfolio management. Alpha is a measure of the excess return of an investment compared to a market index.
Gennadi Sardanashvily is a prominent Russian mathematician known for his contributions to differential geometry, mathematical physics, and the foundations of geometry. He has worked on topics such as the geometry of manifolds, the theory of connections, and the geometric aspects of gauge theories. Sardanashvily has published numerous research papers and is recognized in academic circles for his influence and expertise in these areas.
Die swell is a phenomenon that occurs during the processing of polymers, especially during extrusion. When a molten polymer is forced through a die to take a specific shape (such as in the production of pipes, sheets, or films), it often expands or swells as it exits the die. This swelling is primarily due to the relaxation of the polymer chains as they leave the constraints of the die.
Sergey Timashev is a notable figure in the technology industry, particularly known for his role as the CEO and co-founder of Acronis, a global data protection and disaster recovery company. Under his leadership, Acronis has grown significantly and has become a key player in the field of data management and cybersecurity solutions.
Svyatoslav Gabuda does not appear to be a widely recognized name in publicly available information up to October 2023. It's possible that he could be a private individual, a lesser-known figure, or a fictional character. If you have any additional context or specifics about who he is or the domain in which he is relevant (such as literature, politics, sports, etc.
Yuri Krutkov could refer to a few individuals, but there isn't a widely recognized figure with that name as of my last knowledge update in October 2023. It’s possible he could be a lesser-known individual in fields such as academia, business, or the arts, or a fictional character. To provide more accurate information, please provide additional context or specify the domain in which Yuri Krutkov is relevant.
Christine Davies could refer to various individuals or concepts, depending on the context. Without additional specifics, it's difficult to determine exactly who or what you are asking about. There are likely many people named Christine Davies in various fields such as academia, arts, business, or science.
It seems there may be a misunderstanding regarding the name "George Carse." It's possible that you're referring to George Carlin, a famous American stand-up comedian, social critic, actor, and author known for his dark humor and commentary on various societal issues. If "George Carse" refers to something else, could you please provide more context or clarify?
John Allan Broun is not widely recognized in popular culture, academia, or history based on information available up to October 2021. It is possible that he may be a lesser-known individual or might have gained prominence after that date.
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.
