Ballistic gelatin is a synthetic gelatinous material used primarily in the testing and evaluation of bullets and projectiles. It mimics the density and consistency of human tissue, allowing researchers, forensic scientists, and ammunition manufacturers to study how different projectiles behave upon impact with soft tissues. This is crucial for understanding penetration, expansion, and wound channel creation in ballistic impact scenarios. Ballistic gelatin is typically made from a mixture of gelatin powder and water, set into molds to create blocks or other shapes.
A bulletproof vest, also known as a ballistic vest, is a type of body armor designed to absorb and mitigate the impact of projectiles, such as bullets, and shrapnel from explosives. It is commonly used by law enforcement officers, military personnel, and security professionals to provide protection in combat or dangerous situations. Bulletproof vests are typically made from layers of high-strength fibers, such as Kevlar or Twaron, which are woven together to create a flexible, lightweight material.
Contraves Cora is a programmable medical device designed for the continuous glucose monitoring (CGM) of diabetes patients. It helps users better manage their blood glucose levels by providing real-time data, alerts, and insights into their glucose levels, allowing for more informed decision-making regarding insulin and diet. The device is often part of a broader diabetes management system that includes insulin delivery devices, such as insulin pumps.
External ballistics is the branch of ballistics that deals with the behavior of a projectile in flight after it has exited the barrel of a firearm until it reaches its target. It focuses on the forces and factors that influence the projectile's trajectory, such as gravity, air resistance (drag), wind, and Coriolis effect.
Reactive empirical bond order (REBO) is a theoretical framework used in computational chemistry and molecular modeling to describe the nature of chemical bonds in a molecular system. REBO is particularly important in simulations that require an accurate representation of how atoms interact, especially in the context of covalent bonding and the formation or breaking of chemical bonds.
DNA-binding proteins are a type of protein that have the ability to bind to DNA molecules, typically influencing DNA structure, function, and regulation. These proteins play crucial roles in various biological processes, such as: 1. **Gene Regulation**: Many DNA-binding proteins, including transcription factors, can enhance or inhibit the transcription of specific genes by binding to promoter or enhancer regions.
Lipid bilayer fusion is a biological process in which two lipid bilayers merge to form a single, continuous bilayer. This phenomenon is crucial for many cellular processes, including membrane transport, signal transduction, and the fusion of vesicles with target membranes—such as during neurotransmitter release at synapses, hormone secretion, and viral entry into host cells. The process involves several steps: 1. **Approach**: Two lipid bilayers come into proximity.
Physical oncology is an interdisciplinary field that combines principles from physics, oncology (the study and treatment of cancer), biomedical engineering, and other related sciences to better understand cancer and improve its treatment. The aim of physical oncology is to apply physical concepts and techniques to the challenges associated with cancer diagnosis, treatment, and research.
Tethered particle motion (TPM) is a biophysical technique used to study molecular interactions, conformational changes, and dynamics at the single-molecule level. In TPM experiments, a biomolecule (such as DNA, RNA, or a protein) is typically attached (or "tethered") to a surface via one end while the other end is labeled with a fluorescent particle, usually a microsphere or quantum dot.
The Random Coil Index (RCI) is a quantitative measure used to describe the intrinsic conformational properties of polypeptides or proteins in solution, particularly the propensity of certain amino acid sequences to adopt random coil (or disordered) conformations. It provides insights into the structural characteristics of proteins that do not have a well-defined three-dimensional structure, often referred to as intrinsically disordered proteins (IDPs) or regions within proteins.
Ground Level Enhancement (GLE) refers to an increase in the intensity of cosmic rays at Earth's surface due to solar phenomena. Cosmic rays are high-energy particles, primarily protons, that originate from outside the Solar System. These particles can be influenced by solar activities, such as solar flares and coronal mass ejections (CMEs), which can lead to an increase in the flux of cosmic rays reaching the Earth's surface.
Partial impact theory is not a widely recognized term in academic literature as of my last update in October 2023. However, the concept may relate to theories in various fields, such as economics, environmental studies, or social sciences, where the idea of "partial impact" could involve analyzing the effects of an action or event that doesn't fully affect the entire system or population.
Axial precession, also known simply as precession, refers to the gradual shift or change in the orientation of an astronomical body's rotational axis. For Earth, this means the slow movement of its rotational axis in a circular or elliptical path, which affects the position of the celestial poles over time. The main causes of axial precession are gravitational forces exerted by the Sun and the Moon on Earth's equatorial bulge.
Tidal shock refers to the phenomenon that occurs when the gravitational pull of the moon (and to a lesser extent, the sun) causes significant changes in water levels, resulting in rapid fluctuations in tides. This can lead to dramatic shifts in aquatic environments, affecting habitats and the organisms that live there. In a broader context, "tidal shock" can also refer to the stress placed on marine organisms due to rapid changes in environmental conditions, which can be caused by tidal forces.
Emil Rupp could refer to a few different subjects, but there isn't widely recognized information on a prominent figure by that name in mainstream historical, scientific, or cultural contexts as of my last knowledge update in October 2023.
The Lamb-Dicke regime is a concept in quantum mechanics and quantum optics that describes a particular situation in which the interaction between light (such as photons) and a mechanical oscillator (like an atom, ion, or a mechanical resonator) is characterized by a small coupling strength. This regime is often encountered in scenarios involving trapped ions, optical traps, or other systems where quantum systems are coupled to harmonic oscillators.

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.
